目的:利用网络药理学方法筛选茵陈二陈汤干预非酒精性脂肪性肝炎(non-alcoholic steatohepatitis, NASH)的活性成分、作用靶点，并探讨其干预NASH的作用机制。方法:检索TCMSP筛选得到茵陈二陈汤的有效活性成分及作用靶点。利用GeneCards数据库收集NASH相关基因，采用Cytoscape软件构建药物-靶点和疾病-靶点的可视化网络。构建蛋白相互作用网络，以关键靶点蛋白为基础，实现GO及KEGG通路富集分析。结果:共获得茵陈二陈汤45个有效活性成分，114个药物靶点蛋白，463个NASH相关靶点，药物和疾病共有靶点33个。茵陈二陈汤干预NASH的关键靶点主要为IL6、CASP3、MYC等。GO和KEGG富集分析分别得到34个生物过程和79条相关信号通路，涉及炎症、细胞凋亡、糖尿病、非酒精性脂肪性肝病、肿瘤等。结论:茵陈二陈汤干预NASH具有多途径、多靶点作用的特点，本研究揭示了其作用的关键靶点及涉及的生物学过程和信号通路，为后续相关研究提供参考和依据。“,”Objective:By adopting network pharmacology to study the mechanism of n Yinchen-Erchen Decoction in treating non-alcoholic steatohepatitis (NASH).n Methods:TCMSP was used to collect the chemical constituents of n Yinchen-Erchen Decoction, and the effective active ingredients were obtained. Then the target of action was speculated. GeneCards database was used to collect the related genes of NASH. The visualized network of drug-target and disease-target was established by the Cytoscape software. After the analysis of key target genes, PPI network map was established to enrich GO and KEGG pathways based on key target proteins.n Results:A total of 45 active ingredients and 114 drug target proteins, 463 NASH related genes and 33 drug and disease targets were obtained from the main chemical constituents of n Yinchen-Erchen Decoction. The protein interaction network found that IL6, CASP3, MYC may be the key targets of n Yinchen-Erchen Decoction in the treatment of NASH. GO and KEGG enrichment analysis identified 34 and 79 signal pathways related to inflammation, cell apoptosis, diabetes, NAFLD, cancer and so on.n Conclusions:Yinchen-Erchen Decoction has multi-pathway and multi-target characteristics in treating NASH. It reveals the key targets, biological processes and signal pathways involved, and provide reference and basis for the following study.n
