    摘要:

    目的运用网络药理学预测银翘散治疗上呼吸道感染(upper respiratory tract infection,URTI)的潜在靶点及作用机制。方法 通过中药系统药理学数据库与分析平台(TCMSP)筛选银翘散中的有效活性成分及相关靶点,采用OMIM数据库和GeneCards数据库检索URTI疾病相关靶点,继而获取银翘散和URTI的交集靶点,结合STRING数据库构建蛋白质相互作用(PPI)网络,应用Cytoscape软件实现“成分-疾病-靶点”网络的可视化,并通过DAVID数据库进行基因本体论(GO)富集分析与京都基因与基因组百科全书(KEGG)通路富集分析,预测其可能的作用机制。结果 银翘散共有150个活性成分和117个“药物-疾病”共同靶点,主要活性成分包括了连翘脂、木犀草素、槲皮素、山柰酚、连翘醇、豆甾醇等,关键靶点主要涉及IL-6、TP53、MAPK1、APP、VEGFA、TNF等基因。靶点富集分析结果表明,GO功能相关条目479个,主要涉及炎症、应激反应、免疫应答、信号传导等方面;KEGG相关通路121条,主要涉及Toll样受体信号通路、TNF信号通路、HIF-1信号通路和PI3K/Akt信号通路等。结论 银翘散主要作用于IL-6、TP53、MAPK1、TNF等核心靶点,通过抗炎、抗病毒和调节免疫等相关通路来发挥治疗上呼吸道感染的作用。

    Abstract:

    Objective To predict the potential target and mechanism of Yinqiao Powder in the treatment of upper respiratory tract infection(URTI) by network pharmacology. Methods The active components and related targets of Yinqiao were screened by traditional Chinese medicine system pharmacology database and analysis platform(TCMSP), the disease-related targets of URTI were searched by OMIM database and GeneCards database. Then get the intersection targets of Yinqiao Powder and URTI. The protein-protein interaction(PPI) network was constructed with STRING database, and the visualization of “component-disease-target” network was realized by Cytoscape software. Gene ontology(GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out by DAVID database to predict its potential mechanism. Results 150 active components and 117 “drug-disease” common targets were obtained from Yinqiao Powder. The main active ingredients include(-) -phillygenin, luteolin, quercetin, kaempferol, forsythinol, stigmasterol, etc. The key targets involved IL-6, TP53, MAPK1, APP, VEGFA, TNF, etc. The results of enrichment analysis showed that there were 479 items related to GO function, including inflammation and stress reaction, immune response, signal transduction and so on. There were 121 KEGG related pathways, including Toll-like receptor signaling pathway, TNF signaling pathway, HIF-1 signaling pathway and PI3K/Akt signaling pathway. Conclusion Yinqiao Powder mainly had effects on IL-6, TP53, MAPK1, TNF and other core targets, and played a role in the treatment of upper respiratory tract infections through anti-inflammatory, antiviral and immunoregulation pathways.
