摘　　要：基于中药复方网络药理学方法探讨二黄汤(Erhuang decoction,EhD)治疗急性肺损伤(acute lung injury,ALI)的多成分-多靶点-多通路作用机制。以EhD体内入血成分为研究对象,利用SwissTargetPrediction、DisGeNET、Therapeutic Target Database(TTD)、GeneCards、Online Mendelian Inheritance in Man(OMIM)等数据库预测成分潜在作用靶点,并与ALI疾病预测靶点交集整合,获得二黄汤治疗ALI的潜在靶点。利用String数据库和Cytoscape软件进行蛋白相互作用(protein-protein interaction network,PPI)网络构建;利用DAVID平台进行基因本体论(Gene Ontology,GO)分析和京都基因和基因组百科全书(Kyoto Encyclopedia of Genes and Genomes,KEGG)通路注释;应用Cytoscape软件构建“入血成分-靶点-通路”网络;采用Swissdock在线平台对入血成分与关键靶点进行分子对接。建立小鼠ALI模型,进行肺组织切片、炎症因子检测和Western blot蛋白表达实验,验证EhD对ALI治疗效果。动物实验获得山东大学实验动物中心伦理委员会的批准(批准号:2016020)。结果发现信号传导与转录激活因子3(signal transducer and activator of transcription 3,STAT3)、血管内皮生长因子A(vascular endothelial cell growth factor A,VEGFA)、丝氨酸/苏氨酸蛋白激酶1(RAC-alpha serine/threonine-protein kinase,AKT1)、核转录因子-κB/p65(nuclear factor-kappa B/p65,RELA)等关键靶点148个,主要涉及炎症、氧化应激和细胞凋亡等生物过程,与癌症通路、VEGF信号通路、丝裂原活化蛋白激酶(mitogen-activated protein kinase,MAPK)信号通路、Toll样受体(Toll-like receptors,TLRs)信号通路等通路相关。药效实验显示,EhD能显著降低ALI小鼠炎症因子含量、降低肺损伤程度。Western blot实验显示,EhD能显著下调NF-κB/p65表达,上调核转录因子抑制剂(NF-kappa B inhibitor alpha,IκBα)的表达。本研究从网络药理学的角度初步揭示了EhD治疗ALI的多成分、多靶点和多通路的作用机制,为�Network pharmacological approaches were used to predict the components,targets and pathways of Erhuang decoction(EhD)in the treatment of acute lung injury(ALI).The SwissTargetPrediction platform,DisGeNET,Therapeutic Target Database(TTD),GeneCards and Online Mendelian Inheritance in Man(OMIM)databases were used to predict potential targets of EhD and were integrated with the predicted targets for the treatment of ALI.A protein-protein interaction network model was constructed by using String database and Cytoscape software;the DAVID platform was used for Gene Ontology(GO)analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis.A network of drug components-targets-pathways was constructed by Cytoscape software and the SwissDock platform was used to dock the molecules of EhD found in blood with the key disease targets.An ALI model was established in mice and inflammatory factor detection and Western blot protein expression experiments with lung tissue sections were carried out to verify the effect of EhD in the treatment of ALI.Animal experiment ethical requirements were approved by the Ethical Committee Experimental Animal Center of Shandong University(Grant Number:2016020).We identified 148 potential targets including signal transducer and activator of transcription 3(STAT3),vascular endothelial cell growth factor A(VEGFA),RAC-alpha serine/threonine-protein kinase(AKT1),and nuclear factor-kappa B/p65(RELA).The potential targets are largely associated with the biological processes of inflammation,oxidative stress,and apoptosis.Additional pathways relate to cancer,VEGF signaling,mitogen-activated protein kinase(MAPK)signaling,and Toll-like receptors(TLRs)signaling,along with other signaling pathways.Pharmacodynamic experiments showed that EhD could significantly reduce the content of inflammatory factors and the degree of lung injury of ALI mice.Western blot revealed that EhD could significantly decrease the expression of NF-κB/p65 and upregulate the expression of NF-kappa-B inhibitor alpha(IκBα
