目的:何首乌致肝损伤与HLA-B*35∶01等位基因密切相关,本研究借助机器学习和分子对接技术初步探索何首乌中潜在的HLA-B*35∶01易感成分。方法:通过检索文献和相关数据库,收集不良反应(ADR)与人类的主要组织相容性复合体(HLA)等位基因具有相关性的药物作为阳性数据集,未发现相关性的作为阴性数据集,利用PaDEL-Descriptor软件计算分子描述符,采用朴素贝叶斯(Na6ve Bayes)构建二分类模型。利用模型预测何首乌中与HLA相关的ADR风险成分,并结合分子对接技术进一步分析其与HLA-B*35∶01蛋白晶体的结合能力以及结合模式。结果:使用Na6ve Bayes算法构建的二分类模型平均准确率(ACC)为0.750,利用模型从何首乌41种成分中识别出了28种可能引起与HLA相关的ADR成分。分子对接结果显示何首乌中10种成分与HLA-B*35∶01均具有较好的结合能力。多肽对接结果分析,反式二苯乙烯苷、大黄素-1-O-β-D-葡萄糖苷、大黄素甲醚-8-O-β-D-葡萄糖苷3种成分能够使非HLA-B*35∶01呈递肽P1(LPEPLPQGQLTAY)和P2(EECDSELEIKRY)的亲和性提高,并且与P1和P2间具有优势相互作用。结论:研究基于化学描述符构建分类预测模型,并结合分子对接技术预测何首乌中潜在的3种HLA-B*35∶01易感成分,辅助何首乌特异质肝损伤(IDILI)成分研究。

肝内胆管癌(intrahepatic cholangiocarcinoma, ICC)发病率持续攀升,目前尚无有效治疗药物。免疫微环境在ICC发展中扮演重要角色,是当前研究热点。淫羊藿素(icaritin, ICA)是治疗晚期肝细胞癌的创新中药,被认为有潜在的免疫调控抗肿瘤作用,与中医“扶正”治疗肿瘤的认识潜在相合。然而, ICA是否可用于ICC治疗尚未见研究报道。为此,本研究选取免疫系统完整的原位ICC小鼠模型sgp19/kRas,首次在体内评估了ICA治疗ICC的药效,并通过流式细胞术分析ICA对ICC小鼠肿瘤免疫微环境的影响[本实验所有动物实验均获得首都医科大学动物伦理委员会(中国北京)批准,批准号:AEEI-2023-138]。本研究应用100 mg·kg^(-1)ICA灌胃治疗sgp19/kRas ICC原位小鼠模型,结果显示, ICA治疗3周后能够显著抑制sgp19/kRas ICC小鼠模型的肿瘤生长及肿瘤细胞增殖。通过流式细胞术分析ICA对ICC小鼠肿瘤免疫微环境的影响,结果表明, ICA治疗后能够显著降低M2型巨噬细胞占比,并且显著增加CD3^(+)CD4^(+)T细胞的数量。体外实验阐明ICA能促进巨噬细胞向M1型巨噬细胞极化,抑制其向M2型巨噬细胞极化。此外,转录组学分析结果提示, ICA能够增强Toll样受体9 (TLR9)的表达,影响巨噬细胞一氧化氮代谢合成途径及膜受体相关活性,发挥其巨噬细胞极化调节功能。综上,本研究发现ICA治疗能显著延缓sgp19/kRas ICC小鼠肿瘤进展。机制上, ICA可能通过上调TLR9受体表达水平,促进巨噬细胞向M1细胞的极化,改变肿瘤免疫微环境,进而达到抗ICC的作用。

Guidelines for the Diagnosis and Management of Herb-Induced Liver Injury

Chinese Journal of Integrative Medicine 2018年第9期24卷 696-706页

作者： wang jia-bo ZHU Yun BAI Zhao-fang wang Fu-sheng LI Xiu-hui XIAO Xiao-he Integrative Medical Center 302 Military Hospital of China Research Center for Biological Therapy 302 Military Hospital of China Integrative Medical Center Beijing You An HospitalCapital Medical University

Herb-induced liver injury （HILl） is a type of adverse drug reactions related to using Chinese medicine （CM） or herbal medicine （HM）, and is now a growing segment of drug-induced liver injury （DILl） worldwide. Owing to the complicated compositions and miscellaneous risk factors associated with the clinical usage of CM or HM, it is more challenging to diagnose and manage HILl than DILl. In the present guideline issued by the China Association of Chinese Medicine （CACM）, the authors present an evidence chain-based workflow with 9 structured judgment criteria for diagnosing HILl. The 3 diagnostic ending points--suspected diagnosis, clinical diagnosis, and confirmed diagnosis--could be reached according to the length of the evidence chain acquired in the structured diagnostic workflow. Either identifying the species of CM or HM or excluding adulterations and toxin contaminants was strongly recommended to improve the level of evidence for a clinical diagnosis of HILl. In addition, the authors report that the improper use of CM, which violates the general law of CM theory, is one of the most important factors that contributes to HILl and should be avoided. By contrast, based on syndrome differentiation, some CM can also be used to treat HILl if used in accordance with the general law of CM theory. Therefore, 9 recommendations are put forward in this guideline.
