| 1 | 马兜铃酸肝脏致癌性争议及药物安全性思考显示文摘马兜铃酸是一类硝基菲类羧酸,广泛分布于马兜铃科植物中,主要化合物包括马兜铃酸Ⅰ、Ⅱ、Ⅲ、Ⅳ4种。长期服用含马兜铃酸药物可导致马兜铃酸肾病,诱发泌尿系统肿瘤。马兜铃酸的活性代谢产物可与DNA形成加合物,诱导基因发生A-T颠换突变,该突变常被作为马兜铃酸特征性标签。2017年Sci Transl Med报道指出,马兜铃酸及其衍生物与包括中国台湾在内的亚洲地区肝癌发生相关,认为应将避免使用马兜铃酸列为肝癌的一级预防策略。该报道引发了国内外研究者对于马兜铃酸是否具有肝脏致癌性的一系列探讨,本文即针对这一热点问题进行分析,主要讨论已有报道中马兜铃酸肝脏致癌性的争议点,科学客观地评价马兜铃酸与中国人群肝癌发生的关系,同时探讨含马兜铃酸药物安全使用仍需解决的问题,提出药物安全使用的一些思考。 | 陈淑桢 董亚萍 文文 王红阳 | 2021 | 第二军医大学学报2021，42，1： | 8 |
| 2 | Aristolochic Acid-Induced Genotoxicity and Toxicogenomic Changes in Rodents显示文摘Aristolochic acid(AA)is a group of structurally related nitrophenanthrene carboxylic acids found in many plants that are widely used by many cultures as traditional herbal medicines.AA is a causative agent for Chinese herbs nephropathy,a term replaced later by AA nephropathy.Evidence indicates that AA is nephrotoxic,genotoxic,and carcinogenic in humans;and it also induces tumors in the forestomach,kidney,renal pelvis,urinary bladder,and lung of rats and mice.Therefore,plants containing AA have been classified as carcinogenic to humans(Group 1)bytheInternational AgencyforResearchonCancer.In our laboratories,we have conducted a series of genotoxicity and toxicogenomic studies in the rats exposed to AA of 0.1–10 mg/kg for 12 weeks.Our results demonstrated that AA treatments induced DNA adducts and mutations in the kidney,liver,and spleen of rats,as well as significant alteration of gene expression in both its target and nontarget tissues.AA treatments altered mutagenesis-or carcinogenesis-related microRNA expression in rat kidney and resulted in significant changes in protein expression profiling.We also applied benchmark dose(BMD)modeling to the 3-month AA-induced genotoxicity data.The obtained BMDL10(the lower 95%confidence interval of the BMD10 that is a 10%increase over the background level)for AA-induced mutations in the kidney of rats was about 7μg/kg body weight per day.This review constitutes an overview of our investigations on AA-induced genotoxicity and toxicogenomic changes including gene expression,microRNA expression,and proteomics;and presents updated information focused on AA-induced genotoxicity in rodents. | Xi-Lin Li Xiao-Qing Guo Hai-Rong Wang Tao Chen Nan Mei | 2020 | World Journal of Traditional Chinese Medicine2020，6，1： | 5 |
| 3 | 马兜铃酸及马兜铃科中药临床使用风险差异研究显示文摘目的 梳理马兜铃酸毒性与马兜铃科中药的差异,为有毒中药临床合理使用提供借鉴和参考,避免公众混淆。方法 通过文献调研,回顾含马兜铃酸制品引发的安全用药问题,梳理含马兜铃酸中药的使用风险,同时总结既往马兜铃酸减毒研究。结果 马兜铃酸问题与马兜铃科中药两者本质不同,遵循中医药理论指导,临床合理使用含马兜铃科中药,不会引起严重不良反应。结论 建议提高我国有毒中药的科学监管能力和水平,避免盲目的中医药毒性或安全性质疑,为中药行业发展注入积极力量。 | 朱文静 张立丹 周玥 雷海民 | 2022 | 中国药物警戒2022，19，11： | 3 |
