摘　　要：目的:基于系统网络药理学与分子对接技术探讨保肾灵丸治疗糖尿病肾病(DN)的作用机制。方法:查询中药药理学数据库获取保肾灵丸活性成分及作用靶点,与疾病靶点取交集。对交集靶点进行蛋白质互作(protein-protein interaction,PPI)网络构建,并进行GO和KEGG富集分析,得到关键靶点和小分子进行分子对接验证。结果:共预测到活性成分60个及治疗DN靶点112个。关键成分为香芹甾醇、3,9-二-O-甲基尼索林、香芹酚、棕榈苷A和16α-羟基脱氢曲霉醇酸,尤其是香芹甾醇、棕榈苷A和16α-羟基脱氢曲霉醇酸。关键靶点为PIK3CA、MAPK1、AKT1、PIK3R1、BCL2等,与多种癌症相关通路及糖尿病并发症中的AGE-RAGE信号通路、内分泌抵抗、脂质与动脉粥样硬化等通路密切相关。结论:保肾灵丸治疗DN的作用机制具有多成分、多靶点、多通路的特点,各中药之间有协同作用,为保肾灵丸药理作用研究提供依据。Objective:To explore the mechanism of kidney-protecting spirit pill for the treatment of diabetic nephropathy(DN)based on the network pharmacology and molecular docking technology.Methods:The database of TCMSP and Swiss Target Prediction was searched to obtain the active ingredients and targets of kidney-protecting spirit pill,and the intersection with the disease targets was obtained.The protein-protein interaction(PPI)network of intersection targets was constructed,GO and KEGG enrichment were analyzed.The key targets and small molecules were obtained and their interactions were verified by molecular docking.Results:A total of 60 active ingredients and 112 therapeutic DN targets were predicted.The key components were Cerevisterol,3,9-di-O-methylnissolin,Jaranol,Palmidin A and 16α-Hydroxydehydrotrametenolic acid.The key targets were PIK3CA,MAPK1,AKT1,PIK3R1 and BCL2,which were closely related to cancer-related pathways,AGE-RAGE signaling pathway,endocrine resistance,lipids and atherosclerosis pathways in diabetic complications.Conclusion:The mechanism of kidney-protecting spirit pill in the treatment of DN is characterized by multi-components,multi-targets and multi-pathways,with synergistic effects between the herbs,which provides a basis for the study of the pharmacological effects of kidney-protecting spirit pill.
