化毒为药：砒霜治疗白血病（英汉对照）

化毒为药：三氧化二砷对急性早幼粒白血病治疗作用的发现（英汉对照） 饶毅，黎润红，张大庆
摘要 在三氧化二砷（ arsenic trioxide ， ATO ）被视为 “ 对急性早幼粒白血病（ APL ）病人最为有效的单体 ” （ Sanz et al. , 2009; Tallman and Altman, 2009 ）的情况下，令人惊讶的是：最重要的发现者鲜为人知、其原始论文迄今未被一篇英文研究论文所引用。该发现产生于文化大革命时期，当时大多数中国科学家和医生处于困难时期。始于乡村中医针对性含糊的复方，张亭栋与同事于 1970 年代提出复方中单一的化学分子起作用、其最敏感对象为 APL （张亭栋等， 1973 ；张亭栋和荣福祥， 1979 ）。张亭栋和同事二十多年的工作扫除了 “ 能否 ” 和 “ 如何 ” 有效使用 ATO 的困惑。此后中国和西方的其他研究者跟随张亭栋等的先驱工作。张亭栋小组回顾性分析自己的资料证明 APL 确实为 ATO 最敏感的对象（张亭栋和李元善， 1984 ；孙鸿德等， 1991 ）。张亭栋所在医院另一研究组将原本微量的氯化亚汞从配方中完全去除证明 ATO 单独可以治疗 APL （张鹏等， 1996 ）。 1998 年西方研究者发表重复和证明中国发现的论文导致 ATO 疗法被广泛接受（ Soignet et al. , 1998 ）。不过， ATO 相关英文论文的西方或中国作者皆未引用张亭栋等 1970 年代的文章。本文集中介绍张亭栋等早期文献，但也提示进一步研究和验证中国报道 ATO 对其他肿瘤的作用，认为中国刊物发表的一些发现可能对病人有相当价值、其他国家的医生可能得益于有最大病人群落的中国医生之临床经验。 急性早幼粒白血病（ APL ）曾为急性白血病中发病最凶险和后果最致命之一，而现在是最能被治疗的白血病之一。虽然对 APL 的治疗还有可改进的余地，过去几十年来其治疗有很显著的改善，因为四类药物的应用：阿糖胞苷（ cytarabine ， arabinosyl cytosine, Ara-C) (Ellison et al. , 1968) ；蒽环类抗生素（ anthracyclines ） (Boiron et al. , 1969; Bernard et al. , 1973; Bernard, Weil and Jacquillant, 1974) ；三氧化二砷（ arsenic trioxide ， As ₂ O _{3 ，} ATO) (Zhang et al. , 1973; Departments, 1974; Rong and Zhang ， 1979; Zhang and Rong, 1979) ；和全反型维甲酸（ all-trans retinoic acid ， ATRA ） (Huang et al. , 1987, 1988) 。
四类药物中，阿糖胞苷、蒽环类抗生素（如 柔红霉素， daunorubin ）和维甲酸的发现广为人知，而 ATO 疗法的发现史鲜为人知： 多数 APL 研究者引用 1990 年代的论文，晚于原创论文近二十年；有些作者不清楚 ATO 的最初发现者。这些错误令人遗憾，特别是考虑到欧洲白血病国际专家委员会已认为 ATO 是 “APL 疗法中最具生物学活性的单体 ” （ Sanz et al. , 2009 ）、也被认为是 “APL 病人最有活性的单体 ” （ Tallman and Altman, 2009) ，而 ATO 与 ATRA 合并用药可能 “ 在不久的将来，在多数、如果不是全部病人中，替代传统疗法 ” （ Tallman and Altman, 2009 ）。过去十余年来见证了 ATO 的普遍接受（ Sanz and Lo-Coco, 2011 ）、愈来愈多的证明 ATO 在初发和复发 APL 病人中的作用（ Powell et al. , 2010; Estey, 2011 ）。
不知道和混淆早期工作的部分原因是早期文献发表于中国人也少读的中文期刊，但还有其他更复杂的因素。本文总结早期文献，从发现 ATO 治疗白血病到普遍接受 ATO 治疗 APL 。我们也提供早期中文文献的英文翻译，以便西方作者引用。
本文作者并非白血病的研究者，而是以科学史研究者的身份写此文。我们希望白血病的研究者和医生更为仔细地阅读原始文献。 1 ATO 发现的文化环境和非典型历史 1960 年代中期至 1970 年代中期，中国处于文革的动荡期，直接和间接影响了多于一代的中国人。有观点认为今天中国发生的部分乃文革的后果或对文革的反应，多数人认为文革是负面的，如果不是灾害性的。
文革很多极左政策，多数是有害的，但有些有混合、甚至正面的作用，这些正面作用有些源于政策制定者的意图、有些并非原意。一个政策是改善农村医疗条件，从城市医院派遣 “ 流动医疗队 ” 到乡村服务，医疗队走访多个村庄、医疗队成员轮换；另一政策是强调中国传统医药。这两项政策的交汇导致当时很多 “ 发现 ” 中医药有很强疗效的声称，其中多数在几年内被遗弃。但是，少数经受了时间的考验。 ATO 的发现是这种例子。
砷曾长期为中外使用。多种传统中药配方含砷，但通常含多种化学分子、针对的疾病不非常清晰。西方使用砷也不确定（ Sears, 1988 ）。例如， 1786 年英国的 Thomas Fowler 发明含砷化钾（ KAsO ₂ ）的溶液，用于疟疾、间歇热、周期性头痛等（ Sears, 1988 ）。 1845 年发现白血病后， Fowler 氏液于 1865 年曾被用于治疗白血病，并于 1931 年再度用于白血病（ Jolliffe, 1993 ），其后砷和放射作为治疗慢性髓细胞白血病（ chronic myelocytic leukemia ， CML ）的主要疗法， 直至 1953 年被马利兰（ busulfan ）化疗所替代（ Sears, 1988; Jolliffe, 1993 ），不再是西方治疗白血病的常规药物 。
1958 年，中国哈尔滨医科大学的关继仁试用 Fowler 液治疗白血病，结论是砷剂无效（ Guan, 1958 ）。
1950 和 1960 年代，北京的周霭祥和上海的顾德謦使用含硫化砷的中药复方治疗白血病（ Gu, 1964 ）。 1972 年，一个标明 “ 内部资料 ” 的刊物 “ 辽宁抗癌战讯 ” 发表朝阳人民医院儿科的文章，报道用砷剂和化疗合并治疗 16 例儿童急性粒细胞白血病。这一治疗未分开砷剂和其他化疗，不清楚砷剂是否有超出其他化疗已有的效果，也不知道有多大效果：未报道 16 例病人的成功率、仅分析了一例的血象。
1974 年中医研究院血液组总结了全国当时已经试过的、基于中医药的白血病治疗途径和药物，它列了硫化砷（ As ₂ S ₃ ）和蟾酥（以及其他，包括完全西方发明的药物）（ Hematology Group, 1974 ）。它将关继仁（ 1964 ）和朝阳人民医院（ 1972 ）作为支持 As ₂ S ₃ 疗效的两篇文献。需要指出，顾德謦和周霭祥并未将他们的复方化解为单方，即使到今天（如， Zhou ， 1998 ； Hu et al. , 2011 ）。因为含 As ₂ S ₃ 的中药制备过程并无使 As ₂ S ₃ 氧化为 ATO 的高温，在这些砷剂中 As ₂ S ₃ 与 ATO 的关系不明。 1974 年的综述没有结论建议用哪种中药治疗白血病，该文所讨论治疗白血病的蟾酥和多种其他中药其后并未成为任何亚型白血病的标准疗法。
总之， 至 1974 年，并无定论用什么中药治疗白血病、已试过的中药的有效性也未确切公认 。
1970 年代初，哈尔滨医科大学附属第一医院药剂科的韩太云参加巡回医疗队，得知乡村中医用含砷、汞和蟾毒等的复方治疗淋巴结核和多种癌症。 1973 年 3 月，韩太云将这三者做成注射液，他按年月命名为 “713” 溶液、亦称 “ 癌灵 ” 。肌肉注射 “713” 对有些癌症病人有效，一时风靡当地，但又因其毒性很快消停。 “713” 针对的疾病并不清晰，其有效成分也未确定。
张亭栋与韩太云同在一个医院。张亭栋出生于 1932 年，于 1950 年代早期学习西医后毕业于哈尔滨医科大学， 1960 年代曾进修中医，长期工作于哈尔滨医科大学附属第一医院中医科。他曾被黑龙江省卫生局派去检查乡村中医所言是否属实，以后张亭栋与韩太云合作。 2 ATO 治疗 APL 的原始发现 : 1973 至 1979 1972 年后，张亭栋与同事将研究集中于白血病。他们也思考了 “713” 的成分，提出砷是唯一的治疗性化学分子，而汞与蟾酥汞无治疗白血病的作用，汞导致肾毒性、蟾酥导致高血压等副作用。从此，他们用的 “ 癌灵 1 号 ” 主要含 ATO 、仅微量汞（ ATO 与氯化亚汞的重量比为 100 ： 1 ），而全无蟾酥。
1973 年，张亭栋与韩太云的第一篇文章发表于当地的中文刊物。张亭栋、张鹏飞、王守仁、韩太云报道 “ 癌灵 ” 治疗 6 例慢性粒细胞白血病（ Zhang et al. , 1973 ）。他们明确陈述所用溶液含 ATO 和微量氯化亚汞 ，所有 6 位病人都在治疗后有改善，他们提到还在治疗急性白血病，但该文中未发表其结果。
1974 年，哈尔滨医科大学第一附属医院中医科和检验科为集体作者在该校的校报发表文章（ Departments, 1974 ），总结 1973 年 1 月至 1974 年 4 月治疗的 17 例白血病人。在观察不同类型白血病后，他们报道癌灵 1 号可以治疗多种白血病，有些可以达到完全缓解（ complete remission ， CR ）。 1976 年，他们以集体作者还发表了 5 例急性白血病的治疗，皆 CR 。
1979 年，荣福祥和张亭栋报道两例急性粒细胞白血病，一例 CR 已 4 年、一例 3 年（ Rong and Zhang, 1979 ）。
1979 年，张亭栋和荣福祥发表当年的第二篇文章，总结他们治疗 55 例急性白血病（ Zhang and Rong, 1979 ）。其中， 23 例从 1973 年至 1974 年仅用癌灵 1 号， 20 例从 1975 年至 1976 年用癌灵 1 号加西医化疗及其他中药， 12 例从 1977 年至 1978 年用癌灵 1 号加中药和化疗。对每个病人，他们显示了白血病的亚型和临床观察。所有 55 例都有一定程度的改善，总缓解率为 70% ，而 12 例为 CR 。他们用的剂量副作用较小。他们以相当于成人剂量十倍的剂量注射到家兔，病理解剖后没有见心、肝、脾、肾的毒性。
1973 年文章报道了他们先驱的发现， 1979 年的第二篇文章代表他们对疗效的理解（ Zhang and Rong, 1979 ）。张等早期工作有三个重要问题： 1 ）他们是否证明治疗作用来源于癌灵一号，而不是其他中药或化疗西药？ 2) 他们是否意识到癌灵 1 号的作用来源于 ATO 而不是溶液中的汞？ 3 ）他们是否知道 ATO 对 APL 的作用？
以上三个问题的答案都可在 Zhang and Rong (1979) 一文看到： 1 ）三例患者（一例成人、两例儿童）只用了癌灵 1 号，未用其他任何西药和中药，疗效显著。论文发表时，儿童存活 4 年多、成人逾 9 给月。当使用其他中药时，他们指出不是治疗白血病，而是支持患者健康状态以便接受治疗； 2 ）他们文章第 11 页提出癌灵 1 号的有效成分是 ATO ； 3 ）他们在文章的第 10 和 11 页反复指出 ATO 最敏感的白血病是法国 - 美国 - 英国 FAB 分型的 M3 型（另一名称为 APL ） 。
我们可以看到，至 1979 年，张亭栋和同事的理解与现在相同： ATO 可以治疗白血病，特别是 M3 型（亦称 APL ）的白血病。 3 张亭栋研究组 1980 至 1990 年代的进一步工作 1981 年，以集体作者（但标明张亭栋为指导，含 8 位其他作者）的文章报道，癌灵 1 号使 73 位急性粒细胞白血病人中 24% 的 CR 、总缓解率 86% （ Department, 1981 ）。 1982 年，张亭栋和李元善在全国会议上报道癌灵 1 号治疗后 CR 的 22 例、以及治疗 98 例非淋巴细胞白血病，张在 1982 和 1983 年总结其工作（ Zhang, 1982, 1983) 。
1984 年，张亭栋和李元善总结他们自 1971 年以来治疗的 81 例患者（ Zhang and Li ， 1984 ）。在 CR 的 22 例中，他们指出 7 例为 M2 型、 15 例为 M3 型。他们再次认为 “ 以 M3 型效果尤为显著 ” 。张亭栋另发文章有关癌灵 1 号对非淋巴细胞型白血病的作用（ Zhang ， 1985 ）。
1991 年， 孙鸿德、马玲、胡晓晨、张亭栋、荣福祥、王钦华、李金梅、冯秀芹 (Sun et al. , 1991) 继续 1984 年张亭栋和李元善的工作。他们报道癌灵 1 号从 1974 年至 1985 年已用于治疗 32 例 APL ，其中 19 例 CR 、 16 例缓解超过 5 年，通过分析更多病例验证了 ATO 治疗 APL 的高效。
1992 年， 孙鸿德、马玲、胡晓晨、张亭栋 （ Sun et al. , 1992 ）以短篇 “ 经验交流 ” 综述了与他们 1991 年文章完全相同的实质内容。奇怪的是，多数英文文章都引用 1992 年这篇文章作为发现 ATO 治疗 APL ，虽然这两篇文章皆中文。
因为张亭栋从 1973 至 1992 年的文章所报道的治疗都含微量氯化亚汞，虽然远低于 ATO （重量比 1:100 ），严格地说，他们未证明氯化亚汞毫无益处，虽然他们在 1973 年的文章中就说过癌灵 1 号的有效成分是 ATO 。
1995 和 1996 年，张亭栋同一医院的张鹏 、王树叶、胡龙虎、施福东、邱凤琴、洪珞珈、韩雪英、杨惠芬、宋颖昭、刘艳平、周晋、金镇敬等发表两篇论文，证明没有汞的情况下，仅有 ATO 也完全有疗效 （ Zhang et al. , 1995, 1996 ）。 1995 文章为摘要，没有明确所用的 “713” 注射液不含汞，不过后来张鹏说明他们只用了 ATO （ Zhang ， 2013 ）。 1996 年文章明确只有 ATO 、无氯化亚汞。他们从 1992 年至 1995 年治疗了 130 位患者，其中 72 例一次或多次治疗。他们治疗初发病人的 CR 可达 73% ，在复发再治病人的 CR 可达 52% （ Zhang et al. , 1996 ）。
在发掘 ATO 研究的过程中，我们没有看到迹象证明传统中医理论对疾病的分型对发现 ATO 的靶疾病有用。在此，我们将传统中国医药分成中医理论（ CMT ）和中药。 CMT 对发现 ATO 治疗白血病重要吗？张亭栋等讨论了依据 CMT 对白血病分五类，但 ATO 对这些类型作用无差别（ Rong and Zhang, 1979; Zhang and Rong, 1979; Departments, 1984 ）。而西医对白血病的分型有助于发现 ATO 的靶疾病。当他们完全放弃 CMT 对白血病的分型时， ATO 对靶疾病的作用更为显著。有趣的是，他们 1973 年第一篇文章并未用 CMT ，而后来的文章提到。缺乏支持 CMT 用处的证据并不能证明 CMT 无用，但迄今不明确 CMT 是否对于传统中药的研究是否重要。 4 中国对 APL 治疗的贡献 阿糖胞苷和蒽类抗生素（包括柔红霉素）等因为西方的研究成为 APL 的一线 药物（ Ellison et al. , 1968; Boiron et al. , 1969; Bernard et al. , 1973 ）。此后，中国因为 ATO 和 ATRA 的发现而有显著改善 APL 的治疗。本文将中国的发现放在当时的历史框架中。
1973 年，中国的张亭栋和同事报道 ATO 对白血病的治疗（ Zhang et al. , 1973 ）。 1979 年张亭栋和荣福祥提出 APL 对 ATO 特别敏感（ Zhang and Rong ， 1979 ） 。
1977 年，美国癌症研究所的 Collins 等成功地从 APL 病人来源的细胞建立了细胞系（ HL-60 ）（ Collins, Gallo and Gallagher ， 1977 。 1978 年， Collins 等用此细胞系筛选药物，找可诱导 HL-60 细胞分化成熟为正常细胞的化合物。 1980 年， Brietman, Selonick and Collins 发现全反型维甲酸（ ATRA ）和 13 顺型维甲酸可以诱导 HL-60 分化为成熟的细胞，相关的化合物如维生素 A 作用低一千倍。他们提出 “ 这一化合物可以提供治疗急性髓细胞白血病的新治疗工具 ” 。
1981 年， Breitman 、 Collins 和 Keene 从白血病患者血中获得白细胞，检测它们对药物的敏感性，发现 ATRA 能够诱导分化的细胞皆来自两位 APL 患者。 1982 年， Olsson 和 Brietman 发现维甲酸也能诱导 U-937 淋巴瘤细胞分化。 1983 年，日本的 Honma 等报道多种化合物可以诱导不同白血病人的细胞分化，发现 ATRA 可以诱导 APL 患者白细胞的分化。美国的 Koeffler (1983) 总结了体外结果，包括用维甲酸和其他化合物诱导细胞分化，认为 ATRA 和 13 顺维甲酸对 APL 白细胞有同等的分化诱导作用。
美国和欧洲的四个研究组分别报道了 13 顺维甲酸成功地治疗 APL 个例：美国明尼苏达的 Flynn 等 (1983) ；瑞典 Lund 的 Nilsson (1984) ；荷兰的 Daenen 等 (1986) ；以及美国西佛吉尼亚的 Fontana, Roger and Durham (1986) 。
1985 年，上海第二医学院的王振义在当地能获得 ATRA ，但不能获得 13 顺维甲酸，他用 ATRA 成功地治疗了一例 5 岁 APL 女孩。 1987 年，他的研究组在《中华医学杂志》发表英文论文，报道单用 ATRA 、或 ATRA 合并其他化疗治 6 例 APL 患者（ Huang et al. , 1987 ）。 1988 年，王振义研究组在国际的《血液》杂志发表他们用 ATRA 治疗 24 例 APL （ Huang et al., 1988 ）。 该文引用了 1980 年 Breitman 、 Selonick, 、 Collins 的文章， 1981 年 Brietman, 、 Collins 、 Keene 的文章，以及 1983 年 Koeffler 报道 ATRA 和 13 顺维甲酸诱导白细胞分化的文章，也引用了 1983 年 Flynn et al. 、 1984 年 Nilsson 、 1986 年 Daenen et al. 及 Fontana et al. 等报道 13 顺维甲酸治疗 APL 的多篇文章 。
Huang et al. 在 1988 和 1987 年的两篇都是英文论文，但 1988 年的文章在美国发表、 1987 年的文章在中国发表，前者获国际关注。与法国医生的直接交流也有助于国际关注。王振义研究组 ATRA 的发现很快被重复。 1989 年，法国的 Chomienne 等将 ATRA 和 13 顺维甲酸分别给两例 APL 患者，比较两个药物的疗效，感觉 ATRA 更有效。 1990 年，同一法国研究组在体外研究了来自于 22 例 APL 患者的白细胞，认为 ATRA 的作用是 13 顺维甲酸的十倍（ Castaigne et al. , 1990 ）。 ATRA 的作用也被中国其他医生验证（如， Chen ZX et al. , 1991 ）。 1991 年，美国的 Warrell 等验证了中国王振义组和法国 Degos 组的疗效，成功地治疗了 11 例 APL 中的 9 例。自此， ATRA 治疗 APL 广为人知。 1997 年， Tallman 等报道用 346 例 APL 比较 ATRA 和此前标准化疗的柔红霉素和阿糖胞苷，发现如果 ATRA 在诱导和维持期都用时疗效高于化疗。
1992 年，段秀绵、辛晓敏、王凤芹、冯秀芹、徐敬肃、宋晓时、张月桂 报道 ATO 体外对白细胞的作用。 1995 年，大连的黄世林、 郭爱霞、向阳 、 王晓波、林慧娴、富丽报道复方青黛片 在 65 位 APL 患者中获 98% 的 CR ，他们用药成分中含硫化砷。
1995 年和 1996 年 2 月，哈尔滨的张鹏、王树叶、胡龙虎、施福东、邱凤芹、洪珞珈、韩雪英、杨惠芬、宋颖昭、刘艳平、周晋、金镇敬报道从 1992 年至 1995 年在 130 位 APL 中单用 ATO 获得 73% 的 CR 。 ATO 与 ATRA 之间无交叉耐受（ Zhang et al. , 1995, 1996 ）。
1996 年 8 月，上海第二医学院血液研究所的陈国强等 19 位作者（包括中间作者张亭栋、最后作者陈赛娟、王振义、陈竺）报道用体外培养的白血病细胞在分子水平研究 ATO 的治疗机理（ Chen et al. , 1996 ）。
1997 年 , 徐敬肃、段秀绵、徐莹、辛晓敏、宋晓红、张亭栋报道一例三度发病的 APL 患者，每次用癌灵 1 号治疗后存活了二十多年（ Xu et al. , 1997 ）。
1997 年，上海血液所的陈国强等报道 ATO 体外作用于白血病细胞的良效关系。 1997 年，上海上海血液所的的沈等 报道 15 例 APL 患者的治疗，其中 10 例单用 ATO ， CR 达 90% 。
1998 年，美国 Sloan-Kettering 癌症研究中心和康奈尔医学院的 Soignet 等在《新英格兰医学杂志》报道他们用 ATO 治疗 12 例复发的 APL 患者， 11 例 CR （ Soignet et al. ， 1998 ） 。
Soignet 等的 1998 年论文很有利于国际接受 ATO 作为 APL 的治疗方式，这是中国医生此前二十多年在国内发表的很多文章未能做到的。 5 缺乏认可 现在，国际和国内都很接受和使用 ATO ，救活了中外患者。但是，发现者基本在学术和医疗社群默默无闻，尽管 2001 年曾有《纽约时报》的报道（ Rosenthal, 2001 ）。更为鲜明对照的是，虽然 ATRA 治疗 APL 导致王振义获得多个国内外荣誉，张亭栋或他的哈尔滨同事没有因为 ATO 治疗 APL 而获一个全国性或国际性奖励。而我们知道， ATO 的发现早 ATRA 十余年，且为欧洲白血病专家委员会认为是 “APL 最具生物学活性的化合物 ” （ Sanz et al. , 2009 ）。
缺乏认可并非因为争议。张亭栋研究组的孙鸿德曾提出专利争议，但提出时间较晚，而且法院判案支持张亭栋。张鹏坚持他第一证明 ATO 无需汞可以单独治疗 APL 。确实， 1979 年张亭栋和荣福祥曾提出 ATO 单独有作用，但他们没有显示单独用 ATO 的资料。孙鸿德和张鹏有重要贡献，但很清楚张亭栋的作用毫无疑问最为关键，他从 1970 年代初到 1990 年代初坚持不懈的工作，改观了人们对砷之用处和效果的想法：以前砷无确切的用法、疗效不定，他的工作后砷的使用实际可行、且疗效显著。
1998 年，陈国强、陈赛娟、王振义、陈竺在中文杂志表示：自 1970 年代初，哈尔滨医科大学通过临床实践发现三氧化二砷可以有效地治疗 APL ，近两年来，我们与哈医大合作，用三氧化二砷溶液治疗对全反维甲酸和化疗耐药的 APL 患者（ Chen et al. , 1998 ）。这类陈述肯定了哈尔滨工作的优先，不过这篇综述文章中没有出现张亭栋的名字、也未引用其 1970 年代的文献 。
几乎没有英文论文意识到张亭栋在 1973 至 1979 年已发表过论文。英文论文，即使是中国学者的英文论文，也仅引 1992 年孙鸿德等（ Sun et al. ， 1992) 、有时引用 1996 年张鹏等的论文（ Zhang et al. ， 1996 ） ，视它们为 ATO 治疗白血病的最早论文。例如， 1998 年 Soignet 等文章重复张亭栋 1970 年代论文、并对国际接受 ATO 起了很大作用，但它称 “ 中国最近报道 ”ATO 治疗 APL 导致 CR ，引用的是 1992 年孙鸿德（ Sun et al. ， 1992) 、 1996 年张鹏等（ Zhang et al. ， 1996) 、 1997 年上海血液所的沈等（ Shen et al. ， 1997) 。从 1998 年 Soignet 等论文不可能知道张亭栋在 1970 年代就有原创的发现，因为文章的基调和引用让读者认为中国的发现是在 1990 年代。
美国的《科学》杂志在 1996 年一篇新闻报道曾提到张亭栋（ Mervis, 1996 ），但却称张亭栋于 1992 年发表论文。
张亭栋本人很少发表英文论文。 2001 年，他与陈国强作为共同第一作者、王振义和陈赛娟作为中间作者、陈竺作为通讯作者在国际杂志《癌基因》发表综述（ Zhang et al. , 2001 ）。在引言部分，他们说 “ 最近 ” 研究 ATO 治疗 APL ，引用的是 1996 年上海血液所等陈国强等（ Chen et al. ， 1996) 。 第二页，他们说 ATO 的研究始于 1971 年，但未引用任何文献；也说他们治疗了包括慢性粒细胞白血病、淋巴瘤、食管癌以及特别是 APL 等多种癌症、上千患者，但还是没引文献。 如此，张亭栋看起来作为第一作者的英文论文也没引用他自己早年的文献，有效地埋葬了 1970 年代的先驱工作 。
2002 年，朱军、陈竺、 Lallemand-Breitenbach 和 de The 在《自然综述癌症》发表综述文章。在描绘 APL 治疗里程碑的图中有张亭栋在 1970 年的工作，但文字部分引用还是 1992 年孙鸿德等（ Sun et al. ， 1992) ，在参考文献中称 1992 年孙鸿德等的文章为 “ 第一篇三氧化二砷治疗 APL 的报道 ” 。
1992 年孙鸿德等和 1996 年张鹏等皆为中文论文，却都未引用 1970 年代的文献。所以，如果有国际学者希望通过有人帮助他们翻译 1992 和 1996 的文章，他们也不可能由此知道 1970 年代的原始文章。
2008 年，王振义和陈竺在《血液》发表 APL 治疗进展的综述，其对 ATO 引用的第一篇是 2002 年朱军等（ Zhu et al. ， 2002) ，后面还引了 1992 年孙鸿德等、 1996 年张鹏等，以及上海血液所三篇文章（ 1996 年陈国强等、 1997 年沈等、 1999 年牛等 ) 。
2011 年，陈赛娟和陈竺等五位作者发表 ATO 治疗 APL 的综述（ Chen et al. ， 2011 ），称 “1970 年代早期，中国东北哈尔滨医科大学一个小组检测了含 1%ATO 和微量氯化亚汞的癌灵 1 号在静脉注射后对多种癌症的作用 ” ，但未说明研究者、也未引用 1970 年代的文献。它 1992 年孙鸿德等作为 “ 癌灵 1 号在 32 位患者中 21 位 CR ，并有 30% 的令人印象深刻的十年存活率 ” ，然后说 “ 单独用 ATO 治疗复发的 APL 是上海血液研究所自 1996 年至 1999 年报道的 ” ，引用上海的文章是 1997 年沈等和 1999 年牛等 , 忽略哈尔滨张鹏等 1995 和 1996 年的两篇文章，其中 1996 年张鹏等说明了只用 ATO 、无氯化亚汞。按照张鹏于 2013 年的博客文章，张鹏等的结果于 1995 年在全国会议上宣读，陈竺等出席会议者应该知道（ Zhang, 2013 ）。但按 2011 年陈赛娟和陈竺等在国际刊物的综述，首先报道单独用 ATO 治疗 APL 不是 1996 年的张鹏等、而是上海血液所在 1997 和 1999 的文章。
2011 年香港一篇文章，跟踪 ATO 治疗 APL 十年的疗效，但它只引用美国作者 2001 年的文章（ Au et al. ， 2011 ），连内地作者 1990 年代的文章也不引 。
这样，本来应该可以读中文的作者无一在发表英文论文时引用了 1970 年代的文章。在当今英文作者连法文和德文也不读的情况下，毫不奇怪他们不知道中文的原始文献。张亭栋的贡献、他发现的准确时间因此而不为国际学术和医疗界所知。 6 注意中文发表的工作之意义 过去，一般倾向于忽视中国的临床研究，语言只是部分理由。有大量病人的中国，其医生常常有多于西方医生的临床经验。有些中国医生，即使是少部分中国医生，可能对治疗有洞见，但只发表在中国刊物。
以 ATO 为例，包括张亭栋在内的中国医生报道了 ATO 治疗多种癌症，从肝癌、胃癌、结肠癌到淋巴瘤（ Li et al. , 1988; Liu et al. , 2005; Guo et al. , 2006 ）。这些似乎值得验证。
间接推断中药成分的严格科学研究还可能有更多发现。例如，一些医院自己试用的药物、和一些中药企业在缺严格测试就猛力推进市场的药物。而可能在严格检验和研究后，会更为有效和有针对性，而更获得国际接受，最终帮助更多病人，挽救更多生命。 致谢 作者之一（ YR ）感谢中医研究院李连达告知两篇文章（ Guan 1958, and Chaoyang People’s Hospital, 1972 ），以及周霭祥和顾德馨的工作。

A drug from poison: how the therapeutic effect of arsenic trioxide (ATO) on acute promyelocytic leukemia (APL) was discovered Yi Rao ^{1, *} , Runhong Li ² and Daqing Zhang ^{2 1} Peking-Tsinghua Center for Life Sciences at Peking University School of Life Sciences and ² Peking University Health Sciences Center Beijing 100871, China ^* To whom correspondence should be addressed. Abstract: It is surprising that, while arsenic trioxide (ATO) is now considered as “the single most active agent in patients with (APL)” (acute promyelocytic leukemia) (Sanz et al. , 2009; Tallman and Altman, 2009), the most important discoverer remains obscure and his original papers have not been cited by a single English paper. The discovery was made during the Cultural Revolution when most Chinese scientists and doctors struggled to survive. Beginning with recipes from a countryside practitioner that were vague in applicable diseases, Tingdong Zhang and colleagues proposed in the 1970s that a single chemical in the recipe is most effective and that its target is APL. More than 20 years of work by Zhang and colleagues eliminated the confusions about whether and how ATO can be used effectively. Other researchers, first in China and then in the West, followed his lead. Retrospective analysis of data from his own group (Zhang and Li, 1984; Sun et al., 1991) proved that APL was indeed the most sensitive target. Removal of a trace amount of mercury chloride from the recipe by another group in his hospital (Zhang et al., 1996) proved that only ATO was required. Publication of Western replication in 1998 made the therapy widely accepted (Soignet et al. , 1998), though neither Western, nor Chinese, authors of English papers on ATO cited Zhang’s papers in the 1970s. This article focuses on the early papers of Zhang, but also suggests it worth further work to validate Chinese reports of ATO treatment of other cancers, and infers that some findings published in Chinese journals are of considerable value to patients and that doctors from other countries can benefit from the clinical experience of Chinese doctors with the largest population of patients. Acute promyelocytic leukemia (APL) had been one of the most aggressive and fatal forms of acute leukemia, but is now one of the most treatable form of leukemia. While there are still room for improvement in treating APL, significant progress have been made in the last few decades by the applications of cytarabine (arabinosyl cytosine,Ara-C) (Ellison et al. , 1968), anthracyclines (Boiron et al. , 1969; Bernard et al. , 1973; Bernard, Weil and Jacquillant, 1974), arsenic trioxide( As ₂ O _3, ATO) (Zhang et al. , 1973; Departments, 1974; Rong and Zhang, 1979; Zhang and Rong, 1979) and all-trans retinoic acid (ATRA)(Huang et al. , 1987, 1988). The discoveries of cytarabine, anthracyclines and ATRA are well known, whereas the history of the discovery of ATO therapy remains unknown. Most APL researchers cited papers published in the 1990s, which were 20 years later than the original papers. Some authors also seem to be confused about the original discoverer of ATO. These mistakes are regrettable when ATO is now considered to be “the most biologically active single drug in APL” by a panel of International Leukemia Experts for the European LeukemiaNet (Sanz et al. , 2009) or “the single most active agent in patients with APL” (Tallman and Altman, 2009) and that the combination of ATO and ATRA holds the promise to “replace conventional approaches for most, if not all, patients in the very near future” (Tallman and Altman, 2009). The past decade has witnessed the general acceptance of ATO (Sanz and Lo-Coco, 2011) and accumulating proof of more ATO applications from relapsed APL to newly diagnosed APL (Powell et al. , 2010; Estey, 2011). Ignorance of, and confusions about, the early work result in part from the fact that the original papers were published in the Chinese language and in journals that are obscure even to most Chinese readers, although there are other factors of a more complex nature. This article summarizes the early papers from the discovery of ATO treatment of leukemia to the general acceptance of the use of ATO in treating APL. We also provide a list of the early papers in English for Western authors to use in citations. We note that the authors of the present article have not worked on leukemia and write this article in our roles as researchers in the history of science. We hope that those working on leukemia can go into more details of the original work 1 Cultural Milieu and Historical Peculiarities of the Discovery In the 1960s and early 1970s, China was in a political turmoil known as the Great Proletarian Cultural Revolution. Although its origins lie in the political intentions of Mao Zedong, the supreme leader of China at the time, the Cultural Revolution has affected more than one generation of Chinese people directly and indirectly. Some would view what is happening in China now in part as a consequence of, or a reaction to, the Cultural Revolution, with most viewing the Cultural Revolution as negative, if not disastrous. Of the many leftist policies during the Cultural Revolution, most were harmful, but some had mixed or even positive effects intended or unintended by the policy maker(s). One policy directly related to Mao was to improve the medical conditions of rural China by sending doctors from urban hospitals to the countryside in “Circulating Medical Teams”. Doctors in such teams will go to multiple villages and members of the team will rotate. Another policy was to emphasize the importance of Chinese medicine and drugs. The interception of these two led to many claims of findings of great effects of some Chinese medicines or treatment, most of which were abandoned within a few years. However, a few have withstood the test of time. The discovery of ATO was one such example. Arsenic has been used for a long time, both in China and in the West. Several traditional Chinese medical recipes contain arsenic, but they were combinations of multiple chemicals with unclear targets. Western uses of arsenic were also ill-defined (Sears, 1988). For example, Thomas Fowler of Britain invented a solution containing potassium arsenite (KAsO ₂ ) in 1786, and used it for agues, remittent fevers and periodic headaches (Sears, 1988). After leukemia was discovered in 1845, Fowler’s solution was used in treating leukemia in 1865, and again in 1931 (Jolliffe, 1993). Arsenic and irradiation were the main forms of treatment for chronic myelocytic leukemia (CML) until 1953, when they were replaced by chemotherary with busulfan (Sears, 1988; Jolliffe, 1993). Arsenic treatment of leukemia was no longer a standard drug for leukemia in the West from then on. In China, Jiren Guang, a doctor in Harbin Medical University, tried to use Fowler’s solution to treat leukemia  in 1958 and came to the conclusion that it was not effective (Guan, 1958). In the 1950s and 1960s, Aixiang Zhou in Beijing and Deqing Gu in Shanghai used combinations that included arsenic sulfate to treat leukemia (Gu, 1964). In 1972, a report appeared in Anti-Cancer Battle News of Liaoning Province, a publication explicitly labeled as “internally circulated materials” under the authorship of Chaoyang People’s Hospital Department of Pediatrics. It reported the treatment of 16 cases of acute granulocytic leukemia children by a combination of arsenic and chemotherapy. Because this treatment did not separate arsenic from the chemotherapy available then, it was unclear whether arsenic was helpful as an addition to chemotherapy, nor was it known how effective the combination was: success rate among the 16 patient was not reported and blood analysis was shown for only one patient. A 1974 review by the Chinese Academy of Traditional Medicine summarized different approaches and medicines for leukemia treatment by traditional Chinese medicine listed As ₂ S ₃ and toad venom (and others, including pure chemicals of Western invention) (Hematology Group, 1974). It cited Guan (1964) and Chaoyang (1972) as supporting the use of As ₂ S ₃ . It should be noted that neither Gu nor Zhou has reduced their recipes to a single component, even today (e.g., Zhou, 1998; Hu et al. , 2011). Because the preparation and processing of the Chinese medicine containing As ₂ S ₃ did not involve the high temperature required for the conversion of arsenic sulfate into ATO, the relation of arsenic sulfate with ATO in such recipes is unclear. The 1974 review did not provide a conclusive recommendation on the type of Chinese medicine for the treatment of leukemia. Toad venom and quite a number of other medicines discussed in that review have not become a standard therapy for any type of leukemia. In summary, by 1974, it was unclear which of the traditional Chinese drugs can be used to treat leukemia and the effectiveness of those tested by then were uncertain. In the early 1970s, Taiyun Han, a pharmacist of the First Affiliated Hospital of Harbin Medical University, was a member of a circulating medical team. He learned that a countryside practitioner of traditional Chinese medicine used a combination of arsenic, mercury and toad venom to treat lymphatic tuberculosis and cancers. In March 1971, Han made a solution that contained these three components, which he called “713” (after the year and month of his preparation) or “Ailin (literally meaning cancer effective)”. Intramuscular injection showed effects in some cancer patients. The “713” solution was hotly sought after locally for a while but faded soon from the public because of its toxicity. The target diseases of 713 were undefined, nor were the active chemical in 713. Tingdong Zhang was a doctor in the same hospital as Han. Zhang was born in 1932 and graduated in the 1950s from Harbin Medical University, after studying the regular (Western) medicine. He took classes of traditional Chinese medicine in the 1960s. He worked in the Department of Traditional Chinese Medicine of the First Affiliated Hospital of Harbin Medical University. He was initially asked by the Health Bureau of Heilongjiang province to examine the validity of the claims of the countryside practitioner and later collaborated with Han. 2 Original Discovery of the Effective Treatment of APL by ATO: 1973 to 1979 After 1972, Zhang and colleagues focused their research on leukemia. They also analyzed the components of “713” and suggested that arsenic was solely responsible for the therapeutic effect, whereas mercury caused kidney toxicity and toad venom caused hypertension. Neither of the latter two was therapeutically useful for leukemia. From then on, their recipe of Ailin I was mainly ATO with a trace amount of mercury (at a ratio of 100 to 1 by weight), without toad venom. The first paper by Zhang and Han was published in 1973 in a local Chinese journal. Tingdong Zhang, Pengfei Zhang, Shouren Wang and Taiyun Han reported that they had used “Ailin solution” (also known as “Ailin I”) to treat six cases of chronic granulocytic leukemia (Zhang et al. , 1973). They explicitly stated that the components of the solution were ATO and a trace amount of mercury chloride. All six patients improved after the treatment. They also mentioned that acute leukemia patients were being treated, but with no results in that paper. In 1974, under the collective institutional authorship of the Department of Traditional Chinese Medicine and the Department of Laboratory Medicine of Harbin Medical University, they published a report in the university journal (Departments, 1974), summarizing the treatment of 17 cases of leukemia patients from January 1973 to April 1974. After going through different types of leukemia, they reported that Ailin I was effective in treating multiple types of leukemia, leading to complete remission (CR) in acute leukemia patients. In 1976, they used an institutional authorship to publish a report on five cases of acute leukemia in which they had achieved CR. In 1979, Fuxiang Rong and Zhang published two cases of acute granulocytic leukemia, one with CR for 4 and half years and the other for 3 years (Rong and Zhang, 1979). A second paper by Zhang and Rong in 1979 summarized their treatment results from 55 cases of acute leukemia (Zhang and Rong, 1979). 23 leukemia patients were treated with Ailin I alone (from 1973 to 1974), 20 were treated with Ailin I in combination with Western chemotherapy and other Chinese medicines from 1975 to 1976, and 12 treated with Ailin I plus other Chinese medicines and chemotherapy from 1977 to 1978. For each patient, they presented leukemia subtypes and clinical observations. All 55 cases improved to some extent, with a remission rate of 70% and with CR in 12 cases. Side effects were small with the doses they used. They then applied 10 times the equivalent of what they used for adult human patients to 12 rabbits. No toxicity was observed in the heart, the liver, the spleen or the kidney of the rabbits. While the 1973 paper reported their pioneering findings, the second 1979 paper represented their understanding of the therapeutic effect (Zhang and Rong, 1979). There are three important questions about early work of Zhang and colleagues: 1) had they shown that the therapeutic effect came from Ailin I, but not from other Western chemicals or Chinese medicines? 2) had they realized that the effect of Ailin I came from ATO but not from mercury in the solution? 3 ） had they known the effect of ATO on APL? Answers for all three questions can be found in Zhang and Rong (1979) which explicitly stated ： 1 ） that significant improvement was observed in three patients (one adult and two children) used only Ailin I, but no other Western or Chinese drugs. At the time of publication, the children had survived for more than 4 years and the adult more than 9 months. When using other Chinese medicines, Zhang and Rong pointed out that those were not used for treatment of leukemia, but for supporting the general health of the patients so that they could tolerate more treatments; 2 ） that the effective component of Ailin I was ATO (on page 11 of their paper); 3 ） that acute granulocytic leukemia (M3 type of the French-American British FAB classification, also known as APL) was the most sensitive to the treatment, which was a conclusion reiterated on pages 10 and 11 of their paper. We can see that, by 1979, Zhang and his collaborators had clearly reached our current understanding: that ATO could treat leukemia, especially that of the M3 subtype or APL. 3 Further Studies by the Zhang Group from the 1980s to the 1990s In 1981, a paperunder an institutional authorship with a footnote indicating Zhang as the supervisor (with 8 other authors) reported 73 cases of acute granulocytic leukemia patients, with a CR of 24% and remission rate of 86% after Ailin I treatment (Department, 1981). In 1982, Zhang and Li presented a report to a national meeting on 22 cases of CR by Ailin I and on 98 cases of non-lymphatic leukemia. In 1982 and 1983, Zhang published reviews of his work (Zhang, 1982, 1983). Zhang and Li (1984) published a summary of 81 cases which they had treated since 1971. Among the 22 cases of CR, they pointed out that 7 were of the M2 type and 15 were of the M3 type. They again stated that the effect on M3 type were particularly obvious. Zhang (1985) published another paper on the effect of Ailin I on non-lymphatic acute leukemia. In 1991, Hongde Sun, Lin Ma, Xiaocheng Hu, Tingdong Zhang, Fuxiang Rong, Qinghua Wang, Jinmei Li and Xiuqing Hong (Sun et al. , 1991) continued the work of Zhang and Li(1984). They reported that Ailin I had been used to treat 32 APL cases from 1974 to 1985, with CR in 19 cases and that 16 cases had survived for more than 5 years. This confirms the high success rate for ATO treatment of APL. In 1992, Hongde Sun, Ling Ma, Xiaocheng Hu and Tingdong Zhang published a short “Sharing Experience” paper (Sun et al. , 1992), reviewing materials identical to the 1991 paper. Oddly, most English papers cite this 1992 paper for the discovery of ATO treatment of APL, although both papers were in Chinese. Because TD Zhang’s papers from the 1970s to the early 1990s included a trace amount of mercury chloride, in addition to ATO (at a ratio of 1:100 by weight), strictly speaking, they had not proven that mercury chloride did not have a positive effect, despite the fact that their 1973 paper had indicated that only ATO was the effective ingredient in Ailin I. In 1995 and 1996, Peng Zhang and colleagues from the same hospital as Tingdong Zhang published two papers which showed the effectiveness of ATO alone without mercury (Zhang et al. , 1995, 1996). The 1995 paper was an abstract, which did not explicitly state that mercury chloride was not included in the 713 solution, although Zhang later said that they used only ATO. The 1996 paper did show that ATO, but not mercury chloride, was used. They treated 130 APL patients from 1992 to 1995, among which 72 went through one or more courses of treatment. A CR of 73% was observed in patients undergoing initial treatments and 52% in recurrent patients (Zhang et al. , 1996). In the process of uncovering the history of ATO research, we found no evidence that leukemia classification by traditional Chinese medical theories was useful for discovering the target of ATO. Here we separate t raditional Chinese medicine into drugs and theories. Had the traditional Chinese medical theories (CMTs) been helpful for developing ATO as a treatment for leukemia? Zhang and colleagues discussed five types of leukemia based on CMT classification, there was no difference of ATO on different CMT types (Rong and Zhang, 1979; Zhang and Rong, 1979; Departments, 1984). In this regard, the Western classification of leukemia was helpful. When they completely gave up the CMT classification, the effect was more obvious. Interestingly, their first paper in 1973 did not mention CMTs, but their latter papers did. Lack of evidence for the utility of CMTs does not disprove the CMTs, but it is so far unclear whether the CMTs are important or essential for scientific studies of traditional Chinese drugs. 4 Chinese Contributions to APL Treatment Anthracyclines (including daunorubin) and cytarabine became frontline treatment for APL because of research in the West ( Ellison et al. , 1968; Boiron et al. , 1969; Bernard et al. , 1973 ). Chinese contributions in the discoveries of ATO and ATRA came after those, but have significantly improved APL treatment. Here we place the Chinese discoveries in the historical context. In 1973, Zhang and colleagues of China reported the therapeutic effect of ATO on leukemia (Zhang et al. , 1973), and Zhang and Rong (1979) suggested that APL was particularly sensitive to ATO. Collins, Gallo and Gallagher (1977) at the NCI successfully established a cell line (HL-60) from an APL patient. Collins et al. (1978) used it to screen for chemicals which could induce the differentiation of HL-60 cells to mature into normal cells. In 1980, Brietman, Selonick and Collins discovered that all-trans retinoic acid and 13-cis retinoic acid induced HL-60 differentiation into mature cells. Related chemicals such as Vitamin A was 1000 fold less effective. They suggested that “this compound could provide a new therapeutic tool in the treatment of acute myeloid leukemia”. Breitman, Collins and Keene (1981) tested drug sensitivity of leukocytes from the peripheral blood of leukemia patients and found that cells induced to differentiate by ATRA all came from two patients with APL. Olsson and Brietman (1982) showed that retinoic acid could also induce U-937 lymphoma cells to differentiate. In 1983, Honma et al. from Japan reported the effects of multiple chemicals on inducing differentiation of cells from different leukemia patients, and found that ATRA was among those capable of inducing the differentiation of leukocytes from APL patients. Koeffler (1983) summarized in vitro studies including cellular differentiation by retinoic acid and other chemicals, viewing ATRA and 13-cis retinoic acid as equivalent in differentiating APL leukocytes. Single cases of APL treatment by 13-cis retinoic acid were reported by four groups: Flynn et al. (1983) from Minnesota, USA; Nilsson (1984) from Lund, Sweden; Daenen et al. (1986) from the Netherland; and Fontana, Roger and Durham (1986) from West Virginia, USA. In 1985, Zhen-Yi Wang of Shanghai Second Medical College could obtain ATRA (but not 13-cis retinoic acid) from a local source. He used it to successfully treat a five year old girl. In 1987, his group published a paper in the English edition of the Chinese Medical Journal , reporting the use of ATRA (alone or in combination) for the treatment of six APL patients(Huang et al. , 1987). In 1988, Wang’s group published their use of ATRA in the treatment of 24 APL patients in Blood (Huang et al., 1988). It cited Breitman, Selonick, Collins (1980), Brietman, Collins, Keene (1981) and Koeffler (1983) ， which reported the effects of ATRA and 13-cis retinoic acid on inducing the differentiation of leukemia leukocytes, as well as Flynn et al. (1983), Nilsson (1984), Daenen et al. (1986), and Fontana et al. (1986) which reported treatment of APL patients by 13-cis retinoic acid. Huang et al. (1988), but not Huang et al. (1987) (both in English, but the the 1988 paper published in the US and the 1987 paper in China), drew international attention. Direct communication with French doctors also helped. The finding of the Wang group with ATRA were soon replicated. Chomienne et al. (1989) from France compared the effects of ATRA and 13-cis retinoic acid with two APL patients for each chemical and felt that ATRA were more effective. In 1990, the same French group, after working with leukocytes from 22 APL patients in vitro, concluded that ATRA was 10 times more effective than 13-cis retinoic acid (Castaigne et al. , 1990). The effect of ATRA was also confirmed by Chinese doctors (e.g., Chen ZX et al. , 1991). Warrell et al. (1991) in the US replicated the findings of the Wang group in China and the Degos group in France with 9 out of 11 APL patients successfully treated by ATRA. Since then, ATRA was well recognized for APL treatment. Tallman et al. (1997) reported their studies of 346 APL patients, in which they compared the therapeutic effects of ATRA and the previously standard chemotherapy with daunorubin and cytarabine, and found it to be more effective if ATRA was used for both induction and maintenance. Duan et al. (1992) published in vitro studies of the effect of ATO on leukemic cells. Huang and coworkers from Dalian, China reported that a tablet with multiple components derived from traditional Chinese medicines (herbs and minerals) led to 98% CR in 60 APL patients (Huang et al. , 1995). One of the components contained arsenic disulfide. In 1995 and February 1996, Peng Zhang and colleagues from Harbin reported their success in using ATOalone in achieving 73% of CR in 130 APL cases from 1992 to 1995. No cross-resistance was observed between ATOand ATRA (Zhang et al. , 1995, 1996). In August, 1996, Guoqiang Chen and 18 other authors (including Tingdong Zhang in the middle and Saijuan Chen, Zhen-Yi Wang and Zhu Chen as the last authors) reported work from Shanghai Hematology Institute that used in vitro culture leukemic cells for mechanistic studies of the therapeutic effect of ATOon leukemia at the molecular level (Chen et al. , 1996). In 1997, Jingshu Xu, Jingmian Duan, Ying Xu, Xiaomin Xin, Xiaohong Song and Tingdong Zhang reported a case of who had recurrent APL three times (Xu et al. , 1997). The patient was treated with Ailin I every time and had survived for 20 years. Chen et al. (1997) from Shanghai published dose-dependent effect of ATO on leukemic cells in vitro. Shen et al. (1997) from Shanghai reported that they used pure ATO to treat 15 APL patients, among which 10 cases with only ATO . CR was achieved in 90%. Soignet et al. (1998) from the Memorial Sloan-Kettering Cancer Hospital and Cornell Medical College reported in the New England Journal of Medicine ( NEJM ) that they had treated 12 recurrent APL cases with ATO and observed CR in 11 cases. The mechanisms were thought to be partial cellular differentiation and apoptosis. The NEJM paper helped general international acceptance of ATOas a treatment of APL, which could not be achieved by many papers published in China by Chinese doctors over the previous two decades. 5 Lack of Recognition ATO has now been well accepted (and generally used) nationally and internationally, saving lives in China and other countries. However, the discoverer remains largely unknown in academic and medical communities, although there was a 2001 story about him in the New York Times (Rosenthal, 2001). It is more striking that, while the discovery of the effect of ATRA on APL has led to both national and international awards to Zhen-Yi Wang, not a single national or international award has been given to Tingdong Zhang or any of his Harbin colleagues for the discovery of the therapeutic effect of ATO on APL, although ATO was discovered more than a decade before ATRA and is recognized as “the most biologically active single drug in APL” by International Leukemia Experts for the European LeukemiaNet (Sanz et al. , 2009). The reason for lack of recognition is not due to controversies. There was a patent contention by Hongde Sun, a member of Zhang’s group. It was quite late and the judge ruled in Zhang’s favor. Peng Zhang insisted that he was the first to show the effect of ATO alone, without mercury. Tingdong Zhang and Rong (1979) had suggested that ATO alone was effective, but they had not shown data with ATO alone. Both Sun and Peng Zhang have made important contributions, but it is clear that Tingdong Zhang has played an undisputed key role in his persistent work from the 1970s to the early 1990s which turned the often fuzzy arsenic treatment with variable results into practically useful treatment with beneficial effects. Guoqiang Chen, Saijuan Chen, Zhen-Yi Wang and Zhu Chen (1998) published in a Chinese journal that “from the early 1970s, Harbin Medical University discovered through clinical practices that arsenic trioxide could effectively treat APL. In the past two years, we have collaborated with HMU and used arsenic trioxide solution to treat APL patients resistant to ATRA and conventional chemotherapy”, affirming the work and priority of Harbin, though Zhang’s name and papers in the 1970s did not appear in the review (Chen et al. , 1998). Almost no English paper realized that Zhang had published his findings from 1973 to 1979. English papers, including those by Chinese scholars, only cited Sun et al. (1992) and sometimes Peng Zhang et al. (1996) as the first paper(s) for ATO treatment of leukemia. For example, Soignet et al. (1998), which replicated the findings of Zhang in the 1970s and played a major role in the international acceptance of ATO treatment for APL, mentioned “recent Chinese reports” of CR in APL by ATO, and cited only Sun et al. (1992), Peng Zhang et al. (1996), and Shen et al. (1997). It is impossible to know from the NEJM paper that the original findings were made in the 1970s by Tingdong Zhang because both the tone and the citations made it seem that Chinese discoveries were made in the 1990s. A news report in Science did mention Zhang (Mervis, 1996), but stated that Zhang published his paper in 1992. Zhang has published few English papers. In 2001, he and Guoqiang Chen were co-first authors (with Zhen-Yi Wang, Saijuan Chen in the middle and Zhu Chen as the corresponding author) of a review about ATO in an international journal Oncogene (Zhang et al. , 2001). In the introduction, they stated “recent” studies of ATO treatment of APL, citing Chen et al. (1996). On the second page, they stated that the research on ATO began in 1971, without citing any publications, and that they had treated more than a thousand patients of different types of cancers including “chronic granulocytic leukemia, lymphoma, esophageal cancer, and particularly APL” , but again without citing any literature. Thus, Zhang, presumably as the first author of an English paper, neglected to cite his own early papers, effectively burying the pioneering findings in 1970s. In 2002, Jun Zhu, Zhu Chen, Lallemand-Breitenbach and de The published a review in Nature Reviews Cancer . In the figure illustrating milestones in APL treatments, Tingdong Zhang in the 1970s were placed, but the citation in the text was Sun et al. (1992) and the explanation in the reference list credited Sun et al. (1992) as “first report of As ₂ O ₃ therapy in APL”. Both Sun et al. (1992) and Zhang et al. (1996) were published in Chinese, and neither of them cited papers from the 1970s. Thus, even if any international scholars attempted to obtain English translations of the 1992 and 1996 papers, they would  not know the original 1970 papers. In 2008, Zhen-Yi Wang and Zhu Chen reviewed progresses in APL treatment in Blood , with its first citation of ATO as the Zhu et al. (2002) review, andfurther citations for ATO treatment of APL being Sun et al. (1992), Zhang et al. (1996), Chen et al. (1996), Shen et al. (1997) and Niu et al. (1999). Chen et al. (2011) published a review of the therapeutic effect of ATO on leukemia, which stated “in the early 1970s, a group from Harbin Medical University in northeastern China tested Ailing-1 containing 1% ATO and a trace amount of mercury chloride in a variety of cancers by intravenous administration”, without mentioning the researchers or citing papers of the 1970s. The review then cited Sun et al. (1992) for showing “that Ailing-1 induced CR in 21 of 32 patients with APL with an impressive 10-year survival rate of 30%” before stating that “the efficacy of pure ATO in treating relapsed APL was then reported by Shanghai Institute of Hematology (SIH) in 1996-1999”, citing their own papers including Shen et al. (1997) and Niu et al. (1999), ignoring the papers of Peng Zhang et al. from Harbin Medical University who had published a paper in 1995 and one in 1996, which stated that they had used ATO alone (without a trace amount of mercury chloride). According to a 2013 blog by Peng Zhang, his results were known to Chen and others who attended a national meeting in 1995 (Zhang, 2013). However, by ignoring Zhang Peng and colleagues, the Shanghai authors (Chen et al. , 2011) gives the impression that pure ATO was first used by Chen and colleagues in Shanghai Institute of Hematology. A 2011 paper on a ten-year follow-up study of ATO treatment of APL published by Au et al. from Hong Kong cited a paper published by US authors in 2001. Thus, no authors who can read Chinese have cited any of the 1970s papers in their English publications. In the current climate that English authors do not go to original papers in even French or German, it is no wonder that they do not know the titles and authors of the original papers published in Chinese. The contributions of Tingdong Zhang and the precise timing of his discovery are therefore virtually unknown in the international academic and medical communities. 6 Implications of Paying Attention to Work Published in Chinese In the past, there is a general negligence of clinical studies carried out in China. Language is only part of the reason. With the large number of patients in China, many doctors in China have more clinical experience than most doctors in Western countries. Some, even though a small fraction of, Chinese doctors may have insights into treatments that they have only published in Chinese journals. These seem worth further tests and validations. In the case of ATO, for example, Chinese doctors including Zhang and others have reported ATOtreatment of multiple cancers, from liver, stomach and colon cancers to lymphomas (Li et al. , 1988; Liu et al. , 2005; Guo et al. , 2006). An indirect inference is that rigorous studies of components of Chinese medicines may lead to more discoveries. For example, drugs used tentatively by Chinese hospitals or marketed aggressively by Chinese companies (without prior stringent tests), may prove to be more powerful and specific after rigorous studies, and become more internationally acceptable and eventually help more patients and save more lives.

张亭栋等研究三氧化二砷治疗急性早幼粒细胞白血病的部分论文 Treatment of acute promyelocytic leukemia (APL) has been significantly improved through the introduction of cytarabine by Ellison et al. in 1968, daunorubicin by Boiron et al. in 1969, arsenic trioxide by Zhang et al. in 1973 and all-trans retinoic acid by Huang et al. in 1987. Least known among these is the pioneering research of Dr. Tingdong Zhang and colleagues: not a single English paper has cited their important original papers on arsenic trioxide in the 1970s. To help alleviate this problem, I have listed here some of the publications of Dr. Zhang and his colleagues ， with links to PDF files. I recommend that future publications on APL or arsenic trioxide cite Zhang et al. (1973) and Zhang and Rong (1979).

It should be clear from the documented literature that Tingdong Zhang played a pivotal role throughout these studies, with different collaborators contributing to some aspects, but not all, of this line of research. Only Zhang contributed to every key step of this work as well as the entire project.

There have been efforts in China to use traditional Chinese medical recipes that contain arsenic sulfate, but to date, the recipes have not been reduced to single chemicals and the exact relationship of those recipes to arsenic trioxide remains unclear. Thus, work by Zhang and colleagues on arsenic trioxide stands out from these other efforts in its singular success of transforming multiple starting materials into a defined molecule.

What follows are the information for citation, PDF files, brief summaries and background of some of the major papers.

早幼粒细胞白血病 APL 的治疗有显著改善，归功于 Ellison 等（ 1968 ）引入 cytarabine ， Boiron 等（ 1969 ）引入 daunorubicin ，张亭栋等（ 1973 ）引入三氧化二砷，王振义课题组以黄等（ 1987 ）发表的论文引入全反型维甲酸。 这些工作中最不为人所知的是张亭栋医生和同事的先驱工作：没有一篇英文论文引用他们在 1970 年代发表的、有关三氧化二砷的重要原始论文。 为减轻这一问题，我在此列出张亭栋医生和同事的部分文章，并提供 PDF 链接。我建议未来的有关文章引用张亭栋等（ 1973 ），张亭栋和荣福祥（ 1979 ）两篇论文。 有据可查的文献很清晰地显示，张亭栋在这一工作中起了关键作用，不同的合作者对一些不同方面有贡献，但只有张亭栋对该研究的整体、和每个关键步骤都有贡献。 中国另有使用含雄黄的复方的工作，迄今未化解为单体化合物，并不清楚起作用的化学成分，迄今它们与三氧化二砷的关系仍然不明。因此，张亭栋与同事的工作也突出于这些工作，因为只有张亭栋等的工作从多种材料中定义了单个分子。 以下为部分关键论文的引用信息， PDF 文档，和内容、背景简介。

Summary and Background

In this paper, Zhang TD, Zhang PF, Wang and Han reported that they had used “Ailin solution” (also known as “Ailin I”) to treat six cases of chronic granulocytic leukemia. It explicitly stated that the components of the solution were arsenic trioxide and a trace amount of mercury chloride. All six improved after the treatment. It also mentioned that the authors were testing acute leukemia patients

Before this paper, Taiyun Han, a pharmacist at the First Affiliated Hospital of Harbin Medical University, had learned that a country doctor practicing traditional Chinese medicine had used a combination of arsenic,mercury and toad venom to treat lymphatic tuberculosis and cancers. In March 1971, Han dissolved the three components in a solution, which he called“713” (after the year and month of his preparation) or “Ailin (literally meaning cancer effective)”. This was injected intramuscularly into patients, showing effects in some cancer patients. It was hotly sought after by local population, but soon abandoned because of its toxicity. Han neither defined the exact disease(s) that Ailin was against nor revealed the effective chemical component in Ailin.

Tingdong Zhang was a medical doctor in the same hospital as Han. Zhang was initially asked by the Health Bureau of Heilongjiang province to examine the validity of the claims of the countryside practitioner and later collaborated with Han.

This paper was thus a collaboration of Zhang, Han and others. On the one hand, rather than working with a variety of diseases ranging from tuberculosis to multiple types of cancers, Zhang et al.(1973) targeted leukemia. On the other hand, Zhang et al.(1973) used blood analysis, elevating the standard for measuring treatment success, which was not used by country practitioners of traditional Chinese medicine.

张亭栋、张鹏飞、王守仁、韩太云在本文中报道他们用 “ 癌灵注射液 ” （以后也称 “ 癌灵 1 号 ” ）治疗 6 例慢性粒细胞白血病病人。他们明确知道主要用了砒霜的化学成分 “ 亚砷酸（三氧化二砷） ” 和微量 “ 轻粉（氯化低汞） ” 。经过治疗， 6 例病人症状都有改善，其中一例为慢性白血病发生急性变的患者也有效。该文还提到作者们还在研究对急性白血病的治疗效果。 此前，哈尔滨医科大学第一附属医院的药师韩太云得知民间中医用砒霜、轻粉（氯化亚汞）和蟾酥等治疗淋巴结核和癌症。 1971 年 3 月，韩太云将它们改制水针剂，称 "713" 或 " 癌灵 " 注射液，通过肌肉注射，对某些肿瘤病例见效，曾在当地风行一时，但因毒性太大而放弃。韩当时没有确定癌灵适用的特异疾病、亦未确定癌灵几种成分中何为有效成分。 张亭栋是同一医院的医生，黑龙江省卫生厅曾请他检查农村中医声称的医疗效果。 1972 年，张亭栋与韩太云合作。张亭栋等一方面主要集中做白细胞，而非无选择地将药物用于从结核到多种癌症等很多疾病，另一方面，张亭栋等用血象分析等可靠的客观标准检测治疗效果 , 而乡村中医无此标准。

Summary:

This paper summarized 55 cases of acute leukemia. 23 patients were treated with Ailin I alone (from 1973 to 1974), 20 patients treated with Ailin I in combination with Western chemotherapy and other Chinese medicines from 1975 to 1976, and 12 cases treated with Ailin I plus other Chinese medicines and chemotherapy from 1977 to 1978. For each patient, the authors presented leukemia subtypes and clinical observations. All 55 cases improved to some extent, with a remission rate of 70% and with complete remission in 12 cases. The side effect was small with the doses they used. The authors then applied 10 times the equivalent of what they used for adult human patients into 12 rabbits. No toxicity was observed in the heart, the liver,the spleen or the kidney of the rabbits.

Zhang and Rong (1979) explicitly stated that ： 1 ） significant improvement was observed in three patients （ one adult and two children ） treated with only Ailin I, but no other Western or Chinese drugs. At the time of publication, the children had survived for more than 4 years and the adult more than 9 months. When using other Chinese medicines, Zhang and Rong pointed out that those were not used for treating leukemia, but for supporting the general health of the patients so that they could tolerate more treatment; 2 ） the effective component of Ailin I was arsenic trioxide (on page 11 of their paper); 3 ） acute granulocytic leukemia (M3 type of the French-American British FAB classification, also known as APL) was the most sensitive to the treatment, which they reiterated on pages 10 and 11.

Therefore, it can be concluded that, by 1979, Zhang and his collaborators had clearly reached our current understanding: that arsenic trioxide can treat leukemia, especially the M3 subtype or APL.

Zhang et al. (1973) was the pioneering paper, beginning to study the effect of arsenic trioxide on leukemia (but tested only chronic leukemia), while Zhang and Rong (1979) was the most representative paper. Zhang and Rong (1973) made it clear that 1) only arsenic trioxide was required for the treatment; 2) the most sensitive leukemia was the M3 subtype of leukemia (also known as APL).

While different collaborators were involved in 1973, 1974 and 1979, only Tingdong Zhang was always involved and was always a major author, thus establishing his key role in this series of research.

1979 年张亭栋和荣福祥总结他们从 1973 年至 1978 年治疗急性粒细胞型白血病共 55 例。其中 1973 年至 1974 年单用 “ 癌灵一号 ” 治疗 23 例， 1975 年至 1976 年用 “ 癌灵一号 ” 加其他中药和少量化疗药物治疗 20 例， 1977 年至 1978 年用 “ 癌灵一号 ” 加其他中药和加少量化疗治 12 例。对每一个病例，他们都根据血象分型，有明确的疗效观察。全部 55 例都有不同程度的好转，缓解率 70% ， 12 例完全缓解，对病人的毒副作用小。他们还用十倍于成人的剂量，给 12 只家兔注射 “ 癌灵一号 ” ，未见心、肝、脾、肾毒性作用。 张亭栋和荣福祥（ 1979 ）明确指出： 1 ）有三例病人（一位成人、两位儿童），单纯使用 “ 癌灵一号 ” ，不用其他中药、不用化疗西药，也显示疗效，其中当时儿童存活已经 4 年，成人已存活 9 个月。在使用其他中药时，他们也指出其他中药并非治疗白血病、而用来支撑病人身体状况； 2 ）在第 11 页，他们指出 “ 癌灵一号 ” 之有效成分为三氧化二砷； 3 ）在第 10 页和第 11 页，他们两次明确指出对早幼粒型白血病效果最好。也就是说， 1973 年到 1979 年，张亭栋与不同的同事合作发表的论文，清晰地得到了我们今天的认识：三氧化二砷可以治疗白血病，特别是急性早幼粒白血病（法国 - 美国 - 英国 FAB 分型的 M3 型白血病，也即 acute promyelocytic leukemia ， APL ）。 1973 年的论文是他们发现 “ 癌灵一号 ” 的开创性论文，开始将砒霜用于白血病（但当时只报道了慢性白血病），而张亭栋与荣福祥（ 1979 ）是他们这一系列工作的代表性论文。张亭栋与荣福祥（ 1979 ） 论文已经明确： 1 ）癌灵一号只需要三氧化二砷起治疗作用； 2 ）最敏感的白血病是 M3 型的急性粒细胞白血病（后来也称为 APL ）。 有不同的合作者参与 1973 、 1974 、 1979 年发表的工作，而张亭栋自始至终参与，并作为主要作者，所以发表的文献清晰地表明张亭栋的关键作用。 5 Department of Traditional Chinese Medicine of the First Affiliated Hospital of Harbin Medical University (supervisor Zhang TD, writers Li YS, Hu XC, participants Li MX, Zhang PF, Rong FX, Sun HD, Li HR, Wu YX) (1981) A clinical summary of 73 cases treated by Ailin No.1 combined with the dialectic theory.

Summary:

Sun, Ma, Hu and Zhang published this short paper as “Sharing Experience”,reviewing materials identical to those in the 1991 paper. Strangely, most English papers cite this 1992 paper for the discovery of arsenic trioxide treatment of APL. Both the 1991 and the 1992 papers were in Chinese. The key findings were published in Zhang et al. (1973) and the effect on APL was clear in Zhang and Rong (1979). The often cited 1992 paper of Sun et al. (1992) was not substantially different from that of 1979, in either the chemicals applied or the subtype of leukemia treated. There is no scientific reason why Sun et al. (1992) was cited instead of the other papers prior to 1992. 孙鸿德、马玲、胡晓晨、张亭栋这篇作为 “ 经验交流 ” 发表的短文，实质相同于 1991 年论文。比较奇怪的是，英文文献引用这篇文章。该文与 1991 年论文一样都是中文，内容不过是 1991 年论文的简介，而实际发现最早发表于张亭栋等（ 1973 ），到张亭栋和荣福祥（ 1979 ）已明确了对 APL 的作用最好。而 1992 的论文在本质上与 1979 年的文章无差别，既没有改变所用的药物成分、也没有改变适应症。没有科学理由引用孙鸿德等（ 1992 ）而不引用张亭栋等（ 1973 ）、或张亭栋与荣福祥（ 1979 ）。

张亭栋与王振义的同类工作 药用化学分子 对于新药的研究，可以比较我国发现过多少新药，多少个化学单体是因为中国的工作而被全世界应用，我国发明的药物对治疗某个疾病带来多大的推动，我国发明的药物治疗了多少病人，等。
陈克恢于 1920 年代在协和研究麻黄素代表了中国现代药物研究初期的高度。从单分子化学药物角度来说，青蒿素、三氧化二砷和全反型维甲酸无疑是一个世纪以来我国最为突出的工作，它们都是因为中国的关键工作，得以治疗全世界相关的病人，而且迄今仍为我国新药研究和医学疗法希望达到和超越的标杆。
如果比较最突出的青蒿素、三氧化二砷和全反型维甲酸三个药物，青蒿素的工作包括从植物提取新的活性分子，发现新的化学结构。三个药物都有前人工作，青蒿素和三氧化二砷起源于中药的提示，全反型维甲酸起源于西方国家研究的提示。其中，青蒿素与原有知识的距离最远，因为青蒿、黄蒿治疗疟疾在中药并非常用，具体制剂不清楚，《本草纲目》记录的多个制作方法中有些必定灭活青蒿素而无用，民间方剂也鱼龙混杂、无清晰结论。因此，发现青蒿素的工作是同一领域中推动最大的一步。所以，在中国近代化学药物发现中，青蒿素的工作最优。目前我国尚不能做很多这样工作，与国际先进水平还有很大差距，我们自然希望中国将有更多的像青蒿素一样的工作。
评价三氧化二砷与全反型维甲酸的工作，必需清楚现状：我国用的化学药物绝大多数都是抄来的，我国发明和发现了新的药用分子，我国审批机构更是发了很多新药证书，但真正能获得（无论是国内还是国外）医生和市场认同的新药则极少。今天所谓我国的创新药物中多数也以仿造为主，由于我国的关键贡献而导致世界用某种化学药物的例子极少。所以，三氧化二砷与全反型维甲酸确实是我国在化学药物方面突出的两项工作。上海交通大学医学院（原上海第二医学院）的王振义教授因为发现全反型维甲酸治疗 APL 亚型白血病而获得国内外认可（包括 1994 年当选中国工程院院士、 1994 年美国通用汽车癌症奖、 2011 年中国最高科学奖），是完全应该的，因为他的工作在我国发现药物治疗作用方面非常突出，且造福世界。
APL 亚型白血病的治疗 对于新药的研究，纵向是比较同一疾病、或同一药物，我国的工作起了多大的作用。因为三氧化二砷和全反型维甲酸治疗的是同一疾病，所以，较为方便进行纵向（和小范围的横向）比较。
白血病可分为多种亚型，其中一种为 “ 急性早幼粒白血病 ” （ APL ，亦称 FAB 分型的 M3 型）。 1968 年， Ellison 等报道用 阿糖胞苷 治疗 APL 成功 。 1969 年， Boiron 等报道用柔红霉素（ daunorubin ）治疗 APL ， 1973 年 Bernard 等总结了他们 1967 年以来用柔红霉素的成功率。包括柔红霉素的 蒽环类抗生素 (anthracyclines) 和阿糖胞苷为 APL 化疗的标准药物。
在中国的工作推广到世界后，现在国际上 APL 的常用疗法中三氧化二砷和全反型维甲酸赫然占重要地位，超过原有化疗药物（ Sanz ， 2009 ； Tallman and Altman ， 2009 ； Estey ， 2011 ； Powell 等， 2010 ； Sanz 和 Lo-Coco ， 2011) 。三氧化二砷被欧洲白血病国际联盟认为是“治疗 APL 最有生物活性的单个药物” （“the most biologically active single drug in APL” ， Sanz et al. ， 2009) ，被美国同行认为是治疗 APL 患者最有效的单个药物（ “the single most active agent in patients with APL” ， Tallman and Altman, 2009) 。三氧化二砷和全反型维甲酸合并用药可能 “ 在不久的将来在多数，如果不是全部 APL 患者中，替代常规疗法 ” （ holds the promise to “replace conventional approaches for most, if not all, patients in the very near future” ， Tallman and Altman, 2009) 。近年的研究更见证了世界上广泛接受三氧化二砷治疗 APL(Sanz and Lo-Coco 2011) ，并继续有更多证据表明三氧化二砷对新诊断的和复发的 APL 都有治疗作用 (Powell et al., 2011; Estey, 2011) 。
三氧化二砷治疗 APL 我们已在其他文章多次介绍过三氧化二砷的一些细节，此处仅列关键步骤。
从古代到 1960 年代，砒霜和三氧化二砷在中国和外国都有过应用，但其适应症不很明确，有时很泛，而砒霜毒性很大，所以没成为医生普遍接受的治疗某种疾病的标准药物，即使在有人试过的白血病，也未明确哪种白血病适用三氧化二砷。而有些用中药的疗法是合用砒霜和其他药物，不清楚其中有效成分。所以，在国外和国内，砒霜皆非一般医生用来治疗白血病的常规，更不知道 APL 对三氧化二砷最为敏感。
1973 年，张亭栋、张鹏飞、王守仁、韩太云报道用癌灵一号治疗慢性粒细胞白细胞。 1979 年，荣福祥和张亭栋报道癌灵一号治疗两例急性粒细胞白细胞。 1979 年，张亭栋和荣福祥报道总结他们从 1973 年到 1978 年用癌灵一号治疗 55 例白血病患者。在这篇文章中，他们明确指出：只需三氧化二砷起治疗作用，无需其他中药、也无需其他化学成分；三氧化二砷治疗最有效的是急性早幼粒白血病（ APL ）。
1980 、 1990 、 2000 年代，张亭栋和同事继续以此药治疗 APL ，不断证明其有效性。所以，在张亭栋等工作以前，含砒霜的复合药对疾病针对性模糊，而在张亭栋等 1973 和 1979 年的工作以后，才知道三氧化二砷是对 APL 有高度针对性的单一化学药物。
此后，张亭栋和同事的结论不断为其他医生验证和推广，例如 1996 年，哈尔滨医科大学第一附属医院的张鹏等总结他们 1992 年到 1996 年专门治疗 130 例 APL 患者。
1996 年开始，上海第二医学院血液研究所也开始发表论文，介绍他们使用三氧化二砷的疗效和研究。陈竺曾在国际会议上介绍张亭栋，陈竺、陈赛娟、王振义等加入三氧化二砷的研究，国际上不断出现英文论文发表中国的研究结果。
1998 年，国际权威医学刊物《新英格兰医学杂志》发表美国 Soignet 等验证三氧化二砷治疗 APL 的论文，这篇英文论文对三氧化二砷推广到全世界起的作用，是 1970 年代到 1990 年代张亭栋等中文文章无法做到，不过 Soignet 等并非突破而是验证中国的工作。
Soignet 等美国医生不知道张亭栋的工作是 1970 年代做的，误认为中国的工作始于 1990 年代，他们称 “ 中国的研究者最近报道 ” 。他们未引用张亭栋等 1970 年代的工作，而引用： 1 ）孙鸿德 , 马玲 , 胡晓晨 , 张亭栋 （ 1992 ）； 2 ）张鹏 , 王树叶 , 胡龙虎 , 施福东 , 邱凤琴 , 洪珞珈 , 韩雪英 , 杨惠芬 , 宋颖昭 , 刘艳平 , 周晋 , 金镇敬（ 1996 ）； 3 ）沈志祥等（ Shen ZX, Chen GQ, Ni JH, Li XS, Xiong SM, Qiu QY, Zhu J, Tang W, Sun GL, Yang KQ, Chen Y, Zhou L, Fang ZW, Wang YT, Ma J, Zhang P, Zhang TD 张亭栋 , Chen SJ 陈赛娟 , Chen Z 陈竺 , and Wang ZY 王振义 ）（ 1997 ）； 4 ）陈国强等（ Chen GQ ， Zhu J, Shi XG, Ni JH, Zhong HJ, Si GY, Jin XL, Tang W, Li XS, Xong SM, Shen ZX, Sun GL, Ma J, Zhang P, Zhang TD 张亭栋 , Gazin, Naoe T, Chen SJ 陈赛娟 , Wang ZY 王振义 , Chen Z 陈竺 （ 1996 ）。
另外，上海血液研究所的 Chen GQ 等（ 1996 ）在《血液》发表的有关三氧化二砷的文章也未引用 1970 年代的张亭栋文章，引用了孙鸿德 , 马玲 , 胡晓晨 , 张亭栋 （ 1992 ），称 “recently” 。上海血液研究所的 Shen ZX 等（ 1997 ）在其论文引言中说明 1970 年代中国东北发现，但引用的最早文献也是 孙鸿德等（ 1992 ）。 Chen GQ 等（ 1997 ）的《血液》论文也引用孙鸿德等（ 1992 ）。
Chen GQ 等（ 1996 ）、 Shen ZX 等（ 1997 ）、 Chen GQ 等（ 1997 ）和 Soignet 等（ 1998 ）四篇论文是 1990 年代中期对于国际上知晓三氧化二砷很重要的英文文献，但它们都无助于国际上得知张亭栋 1970 年代的文章。
实际上，直到三氧化二砷已经成为国际常用治疗 APL 药物的今天，中外作者的英文文章仍不引用张亭栋等 1973 和 1979 年的文章，包括近年综述也不引用，例如： Wang 王振义 and Chen 陈竺（ 2008 ）， Sanz 等（ 2009 ）， Tallman 与 Altman （ 2009 ）， Powell 等（ 2010 ）， Sanz 与 Lo-Coco （ 2011 ）， Chen 陈赛娟 , Zhou, Zhang, Mao, de Thé 与 Chen 陈竺（ 2011 ）， Estey （ 2011 ） 。
全反型维甲酸治疗 APL 1977 年，美国国立健康研究院国家癌症研究所肿瘤细胞生物学实验室的 Steven Collins 、 Robert Gallo 、 Robert Gallagher 报道他们从一位 APL 女性患者外周血获得细胞，进行培养后获得 HL-60 细胞系，第一次建立 APL 的体外细胞模型。 1978 年， Collins 等鉴于前人对其他白血病细胞的研究，用多种化合物分别处理 HL-60 细胞，发现其中一些可以使 HL-60 癌细胞分化成为正常细胞。
1980 年， Breitman 、 Selonick 、 Collins 等发现，全反型维甲酸和 13 顺型维甲酸可以将 HL-60 分化成为正常的成熟白细胞，其他几种相近的化合物（包括维生素 A 等）作用低于维甲酸一千倍。他们在此文中提出，维甲酸可以提供一种治疗 APL 的新工具（ “this compound could provide a new therapeutic tool in the treatment of acute myeloid leukemia” ）。
1981 年， Brietman 、 Collins 、 Keene 等从 21 例白血病患者获得其外周血中的白细胞，在体外进行药敏检验，能够被全反型维甲酸诱导分化的白血病细胞都是来源于两例 APL 患者。 1982 年， Olsson 和 Brietman 报道维甲酸也可以分化淋巴瘤细胞系 U-937 细胞。 1983 年，日本的 Honma 等报道多种化合物对不同白血病人来源的细胞在体外有诱导分化的作用，其中可以分化 APL 患者白细胞的化合物包括全反型维甲酸。 1983 年，美国洛杉矶加州大学的 Koeffler 综述体外培养白血病细胞的研究，包括维甲酸在内的多种化合物有诱导分化作用，认为全反型维甲酸和 13 顺型维甲酸对 APL 细胞有同等作用。
1983 年，美国明尼苏达大学 Flynn 、 Miller 、 Weisdorf 、 Arthur 、 Brunning 、 Branda 报道用 13- 顺维甲酸治疗一例 APL 患者，而且观察了其细胞在体外的分化。
1984 年，瑞典 Lund 大学医院内科的 Nilsson 用 13- 顺维甲酸治疗一例其他化疗后复发的 APL 患者。
1986 年荷兰的 Daenen 、 Vellenga 、 van Dobbenburgh 和 Halie 报道用 13- 顺维甲酸治疗一例 APL 。
1986 年美国西弗吉尼亚大学的 Fontana 、 Roger, Durham 报道用 13- 顺维甲酸治疗一例 APL 。
1987 年，中国上海第二医学院王振义课题组以黄萌茸为第一作者在《中国医学杂志》发表文章，报道使用全反型维甲酸（合并阿糖胞苷或单独用药）对 APL 的治疗作用。据上海交通大学王振义网页显示，这项工作早在 1985 年王振义课题组用全反型维甲酸成功地治疗了一例 APL 患者（所以当时应该不知道国外 1986 年两篇 13 顺维甲酸的文章）。据王振义和陈竺（ 2008 ）报道， 1980 年代中期用全反型维甲酸是因为当时上海有的维甲酸是全反型，而且当时上海市允许用全反型维甲酸治疗皮肤病。 1988 年，王振义课题组以黄萌茸等在国际血液方面权威学术刊物《血液》报道他们用全反型维甲酸成功治疗 24 例 APL 患者。该文引用了 Breitman, Selonick, Collins （ 1980 ）、 Brietman, Collins, Keene （ 1981 ）以及 Koeffler （ 1983 ），这些文章研究（和综述）全反型和 13 顺维甲酸在体外对白血病细胞诱导分化作用。黄萌茸等（ 1988 ）也引用了 Flynn 等 （ 1983 ） 、 Nilsson （ 1984 ）、 Daenen 等（ 1986 ）、 Fontana 等（ 1986 ）文章，这些文章是国外将 13 顺维甲酸用于治疗 APL 患者。也就是说，王振义课题组在国外这两个系列的工作基础上，开展了自己的工作，成功地证明全反型维甲酸可以用于治疗 APL 患者。
1989 年，在王振义工作的基础上，法国的 Chomienne 、 Ballerini 、 Balitrand 、 Amar 、 Bernard 、 Boivin 、 Daniel 、 Berger 、 Castaigne 和 Degos 用 13 顺维甲酸治疗 2 例 APL 患者、用全反型维甲酸治疗 2 例患者，初步对照感到全反型维甲酸的疗效大于 13 顺维甲酸，他们在体外对培养细胞进行比较也发现全反型维甲酸作用大于 13 顺维甲酸。 1990 年，法国的 Castaigne 、 Chomienne 、 Daniel 、 Ballerini 、 Berger 、 Fenaux 、 Degos 等用全反型维甲酸治疗了 22 例 APL 。 1990 年，法国的 Chomienne 、 Ballerini 、 Balitrand 、 Daniel 、 Fenaux 、 Castaigne 和 Degos 等用 APL 病人的白细胞在体外做的实验表明，全反型维甲酸诱导白细胞分化所需剂量是 13 顺维甲酸的十分之一。因此，法国医生认为应该全反型维甲酸，而非 13 顺维甲酸。
国内对全反型维甲酸的疗效也多次验证。如， 1991 年，苏州医学院的 Chen Zi-Xing 等验证全反型维甲酸对 APL 的治疗作用。
1991 年，美国纽约 Sloan-Kettering 癌症研究中心的 Warrell 等在中国王振义课题组 1988 年文章和法国 Castaigne 等（ 1990 ）年文章的基础上，用全反型维甲酸、但制剂稍改成美国常用胶囊，治疗了 11 例 APL ， 9 例完全缓解。 Warrell 等的工作发表于《新英格兰医学杂志》，有助于全反型维甲酸在美国推广。其后国际上很多验证全反型维甲酸作用的工作。
至此，国内和国际皆公认可以用全反型维甲酸治疗 APL 。
1994 年，王振义当选中国工程院院士。同年，王振义与法国的 Degos 共享美国通用汽车癌症基金会 Charles Kettering 奖。 1997 年王振义获瑞士， 1998 王振义获法国奖项。也就是说，国际国内对王振义的认可皆基于其证明全反型维甲酸的治疗作用，而非以后以陈竺、陈赛娟为主，而王振义也以非通讯作者的身份加入过的机理研究。所以，张亭栋的工作最可比的是王振义的工作。
1997 年，美国西北大学的 Tallman 与合作者在 346 位 APL 病人中比较全反型维甲酸和原有化疗（柔红霉素加阿糖胞苷），发现诱导和维持都用全反型维甲酸的疗效高于原有化疗、也高于维甲酸诱导后用原有化疗，得出清晰的结论：全反型维甲酸应该成为 APL 的治疗方法。 Tallman 等（ 1997 ）的文章发表于《新英格兰医学杂志》，使全世界医生认识到全反型维甲酸优于当时通用的 APL 化疗药物。
1990 年代中期以后工作显示，全反型维甲酸和三氧化二砷可以分别应用、也可以联合治疗，进一步提高 APL 治疗成功率。这些工作中上海血液研究所陈赛娟、陈竺和王振义带领的梯队有很多贡献。
对于 APL 的分子机理， 1977 年，芝加哥大学著名细胞遗传学家 Janet Rowley 等发现 APL 患者细胞中发生了 15 号染色体和 17 号染色体移位（ translocation ）。 1984 年，与 Rowley 一道工作的 Richard Larson 等发现， 27 位 APL 的患者都有同样的 15 号染色体和 17 号染色体交换融合，融合位点全部在 15q22 和 17q21.1 。 1990 年，美国的 Borrow 等）和法国的 de The 等分别发现这一融合的分子结局： RAR a （维甲酸 a 受体）的基因与另外一个基因 PML 融合，可以产生融合蛋白 RAR a -PML 和 PML-RAR a 。 1991 年，意大利的 Alcalay 等得到同样结论。 RAR a 已知为受维甲酸调节的转录因子，而 PML 是含锌指区域的转录因子，这些突破奠定了 APL 分子机理的研究。后续研究表明， RAR a -PML 融合蛋白和 PML-RAR a 融合蛋白调节基因转录，不同于正常 RAR a 蛋白和 PML 蛋白。虽然 15 号与 17 号染色体互换融合产生 PML-RAR a 融合蛋白是 APL 的主要发病原因，还有 1-2% 的 APL 致病是因为 11 号与 17 号染色体移位，这一移位的细胞遗传学发现为 Najfeld 等（ 1989 ）报道，其分子机理为 1993 年陈竺和陈赛娟两篇文章所报道。陈竺、 Brand 、 Chen 、 陈赛娟、 Tong 、王振义、 Waxman 、 Zelent 在《欧洲分子生物学组织杂志》报道一例中国患者的 11 号与 17 号染色体移位导致 RAR a 与另外一个锌指蛋白的基因 PLZF 融合。陈赛娟、 Zelent 、 Tong 、 Yu 、王振义、 Derre 、 Berger 、 Waxman 、陈竺在《临床研究杂志》发表论文发现一例中国患者 APL 患者 11 号与 17 号染色体移位导致 RAR a 与 PLZF 基因融合。 1994 年，陈竺等报道 PLZF-RAR a 融合蛋白可以抑制正常 RAR a 的功能。也就是说，在王振义获得国内、国外认可的关键 1994 年以前， APL 的机理研究以国外为主，而全反型维甲酸治疗 APL 的机理研究还很少。 1994 年后陈赛娟、陈竺还有很多对维甲酸治疗机理的研究， 1990 年代中期以后，陈竺、陈赛娟及王振义课题组起初与哈尔滨医科大学附属第一医院合作研究三氧化二砷的治疗作用，以后陈竺、陈赛娟及王振义对维甲酸和三氧化二砷治疗 APL 的机理还有很多研究，但都在 1994 年以后。从 90 年代至今，药物作用的分子机理方面的工作基本无王振义为主要作者（第一、或者通讯作者）的论文，而以陈竺和陈赛娟课题组为主。
本文讨论的张亭栋工作，最合适的比较是王振义的工作。因为两者都是发现或证明单体化合物的治疗作用，而且是对同一个疾病，所以最可比。王振义在 1994 年获得国内和国际认可原因是他证明全反型维甲酸对 APL 患者的治疗作用，与张亭栋的工作性质相似。不过张亭栋在 1970 年代的论文迄今未被英文文献所引用，所以国际上忽视了那些文章；而由于没有良好的风气，评价体系注重利益而缺乏自尊等多种原因，国内埋没了张亭栋的工作。
直到今天，张亭栋的三氧化二砷与王振义的全反型维甲酸两项工作，仍然是中国医药界突出的工作。 Alcalay M, Zangrilli D, Pandolfi PP, Longo L, Mencarelli A, Giacomucci A, Rocchi M, Biondi A, Rambaldi A, Lo Coco F (1991).
