摘要
目的:探讨苓桂术甘汤功效物质基础及对慢性心力衰竭的作用机制。方法:根据药物ADME特性,借助TCMSP平台遴选苓桂术甘汤中的活性成分和作用靶点,构建成分-靶点网络;基于TTD、Genecards数据库遴选慢性心力衰竭相关的靶点,结合String数据库构建成分靶点-疾病靶点蛋白互作全局网络,并通过生物信息学手段对重叠靶点进行GO注释及通路分析。结果:本研究共获得50个活性成分,对应76个靶点,包括与慢性心力衰竭相关的20个重叠靶点;共富集出38个GO注释条目,经Bonferroni校正P值均<0.01,经Kappa算法分为类固醇激素受体激活、调节心率、调控血压、负调节血压4大类别;获得13条信号通路,经Bonferroni校正P值均<0.05,经Kappa算法分为单胺类G蛋白偶联受体、一氧化氮的调节作用、核受体、叶酸代谢4大类别。结论:本研究结果初步预测了苓桂术甘汤对慢性心力衰竭的基本药理基础及功效机制,与现代临床用药规律契合,为下一步深入验证奠定了良好理论基础。
Objective:To investigate the efficacy and compatibility mechanism of Ling-Gui-Zhu-Gan decoction treatment in Chronic Heart Failure(CHF).Method:We selected active ingredients accoding to drugs' ADME parameters and found the related targets by searching in TCMSP.Meanwhile we built the component-target network and selected chronic heart failure related genes from TTD and Genecards Databases.We constructe component target-disease target protein-protein interaction network searched in String Database and used bioinformatics method to annotate the 20 overlap targets and analyze their enrichment results of GO and pathway.Result:The 50 active ingredients,76 corresponding target,including 20 CHF related targets were screened out.A total of 38GO-terms were enriched,all P value<0.01(Bonferroni-adjusted).According to kappa algorithm,a total of 4groups enriched:steroid hormone receptor activity,regulation of heart rate,regulation of blood pressure,negative regulation of blood pressure.A total of 13pathway-terms were enriched,all P value<0.05(Bonferroni-adjusted).According to kappa algorithm,a total of 4groups enriched:Monoamine GPCRs,Effects of Nitric Oxide,Nuclear Receptors,Folate Metabolism.Conclusion:The result of the study preliminarily verifies the basic pharmacological effects of Ling-Gui-Zhu-Gan decoction and its chronic heart failure related mechanisms.
