A network pharmacology approach to investigate the mechanisms of Si-Jun-Zi decoction in the treatment of gastric precancerous lesions

探讨四君子汤治疗胃癌前病变潜在的作用机制。方法:运用网络药理学分析四君子汤治疗胃癌前病变的活性成分、药物作用靶点及作用通路。通过TCMSP数据筛选四君子汤的活性成分及潜在靶点;通过GeneCards数据库筛选胃癌前病变的疾病靶点。进而对这些靶点进行GO富集和KEGG通路富集分析,从而揭示四君子汤治疗胃癌前病变的作用机制。结果:四君子汤含有111个活性成分,对应胃癌前病变90个靶点。涉及654条GO生物过程与21条信号通路。进而构建出成分-靶点网络、靶点-通路网络及胃癌前病变整合通路,分析结果显示四君子汤主要通过干预胃黏膜炎症、细胞凋亡和增殖过程发挥治疗作用。结论:网络药理学为阐明四君子汤治疗胃癌前病变作用机制提供了新的方法,有助于中医药现代化研究的开展。

Objective:To find out the potential mechanisms of Si-Jun-Zi(SJZ)decoction in the treatment of gastric precancerous lesions(GPL).Methods:A network pharmacology approach was used to analyze the active compounds,drug targets and interacting pathways of SJZ decoction in treating GPL.The compounds and predicted targets of SJZ decoction were screened from TCMSP,and the disease targets were obtained from GeneCards.The therapeutic mechanisms of action of the SJZ decoction were analyzed by gene ontology(GO)enrichment,Kyoto encyclopedia of genes and genomes pathway enrichment analyses.Results:The results show that 111 compounds and 90 targets were obtained in this work.These targets were further mapped to 654 GO biological process terms and 21 remarkably pathways.Active compounds,targets,and pathways were used to construct a compound-target network,a target-pathways network,and an integrated GPL pathway.These results indicated that SJZ decoction may treat the dysfunctions of GPL mainly from intervening in the mucosal inflammation,cell apoptosis process,and cell proliferation.Conclusions:This work provided a novel approach to understand the pathogenesis of GPL and revealed the therapeutic mechanisms of SJZ decoction,which facilitate the modernization of herbal medicine for complex diseases in the future.
