摘　　要：目的:基于网络药理学、分子对接与动物实验探究柴胡龙骨牡蛎合甘麦大枣汤治疗脑卒中后抑郁(PSD)的作用机制。方法:利用TCMSP等数据库预测柴胡龙骨牡蛎合甘麦大枣汤的活性成分及靶点;在PharmGKB等数据库检索PSD疾病靶点,利用Cytoscape(v 3.9.1)建立交集靶点网络,String(v11.5)数据库构建PPI网络,利用DAVID 6.8数据库进行GO富集及KEGG通路分析;运用AutoDock vina(v 1.1.2)软件进行分子对接,并使用Pymol(v 2.5)等软件进行可视化分析;动物实验设置空白组、模型组、盐酸氟西汀组、中药组、中药+盐酸氟西汀组,给药21 d后检测各组大鼠神经行为学评分、脑组织内神经递质以及炎症因子表达,RT-qPCR和Western blot检测关键基因PPARG、MAPK3、AKT1、PIK3CA mRNA及蛋白表达。结果:得到柴胡龙骨牡蛎合甘麦大枣汤活性成分225种,作用于PSD的靶点119个,关键靶点包括MAPK3、AKT1、PIK3CA、PPARG,关键通路包括MAPK信号通路、PI3K-Akt信号通路等。与模型组比较,中药组与中药+盐酸氟西汀组MAPK3 mRNA及蛋白表达降低,AKT1、PIK3CA、PPARG mRNA及蛋白表达升高(P<0.05)。结论:柴胡龙骨牡蛎合甘麦大枣汤治疗PSD的作用机制可能与抑制MAPK3表达、促进AKT1、PIK3CA、PPARG表达,减缓脑组织炎症反应和氧化应激有关。Objective:To explore mechanism of Chaihu Longgu Muli Decoction and Ganmai Dazao Decoction in treatment of post-stroke depression(PSD)based on network pharmacology,molecular docking and animal experiment.Methods:TCMSP and other databases were used to predict active components and targets of Chaihu Longgu Muli Decoction and Ganmai Dazao Decoction.Targets of PSD were retrieved from PharmGKB and other databases,and"component-intersection target-disease"network was constructed by Cytoscape(v3.9.1)software.PPI network was constructed by String(v11.5)database,and GO enrichment and KEGG pathway analysis of intersection targets were performed by DAVID6.8 database.AutoDock vina(v1.1.2)software was used for molecular docking.Pymol(v 2.5)and other softwares were used to visualize optimal docking results.Animal experiments were setup in control group,model group,fluoxetine group,TCM group and TCM+fluoxetine group,neurobehavioral scores and expressions of neurotransmitters and inflammatory factors in brain tissues were detected.mRNA and protein expressions of key genes PPARG,MAPK3,AKT1,PIK3CA were detected by RT-qPCR and Western blot.Results:A total of 225 kinds of active ingredients of Chaihu Longgu Muli Decoction and Ganmai Dazao Decoction were obtained,which acted on 119 targets of PSD,among which key targets included MAPK3,AKT1,PIK3CA and PPARG,key pathways including MAPK signaling pathway,PI3K-Akt signaling pathway and etc.Compared with model group,MAPK3 mRNA and protein expressions were decreased,AKT1,PIK3CA,PPARG mRNA and protein expressions were increased in TCM group and TCM+fluoxetine group(P<0.05).Conclusion:Mechanism of Chaihu Longgu Muli Decoction and Ganmai Dazao Decoction in treatment of PSD may be related to inhibition of MAPK3 expression,promotion of AKT1,PIK3CA,PPARG expressions,alleviation of inflammatory response and oxidative stress in brain tissues.
