基于网络药理学探讨活血化瘀药治疗子宫内膜异位症的作用机制

目的 利用网络药理学探究活血化瘀药治疗子宫内膜异位症（endometriosis，EM）的可能作用机制。方法 以桃仁、红花、泽兰、丹参、益母草、川牛膝、王不留行等七味临床常用活血化瘀中药为研究主体。利用中药化学成分数据库TCMSP平台，检索获取七味活血化瘀药有效活性成分，通过Targets information软件获得有效成分对应靶点。使用GeneCards数据库收集EM相关靶基因，利用韦恩图工具得到活血化瘀药有效成分治疗EM的靶基因。应用Cytoscape 3.6.0软件构建活性成分－作用靶点－疾病网络。应用KEGG数据库分析获得靶点基因富集的信号通路。结果 七味活血化瘀药共筛选出94种活性成分，119个作用靶标。其中槲皮素、木犀草素、山柰酚等为关键活性成分，PTGS2、PTGS1、NCOA2、NCOA1等为关键靶点。七味中药共有20条EM相关KGEE通路，涉及性激素、炎症、细胞调亡以及血管生成等各个方面，其中PI3K-Akt、IL-17、TNF-α等炎症相关通路为主要通路。结论 活血化瘀药治疗EM具有多成分、多靶点、多通路的特点，针对EM的疼痛、炎症以及月经紊乱状态均有治疗作用。

A network pharmacology approach to explore mechanisms of activating blood circulation and removing blood stasis herbs in the treatment of endometriosis

Objective To explore the possible mechanism of activating blood circulation and removing blood stasis herbs in the treatment of endometriosis (EM) with network pharmacology approach.Methods Seven kinds of commonly used activating blood circulation and removing blood stasis herbs, such as: peach kernel, safflower, zeilan, salvia miltiorrhiza, leonuri, radix cyathulae, and wang buliuxing were selected as the research subjects. TCMSP platform, a database of traditional Chinese medicine chemical ingredients, was used to retrieve the effective ingredients of 7 herbs. The targets of the effective ingredients were obtained through the Targets information software. GeneCards database was used to collect EM related target genes. Venn diagram tool was used to obtain the target genes of active ingredients of activating blood circulation and removing blood stasis herbs. Cytoscape 3.6.0 software was used to construct the active ingredient-target-disease network. KEGG database was used to analyze the signal pathways of target gene enrichment.Results A total of 94 active ingredients and 119 targets of 7 herbs were screened. Quercetin, luteolin and kaempferol were the key active components. PTGS2, PTGS1, NCOA2 and NCOA1 were the key targets. The 7 herbs have 20 related KGEE pathways, involving sex hormones, inflammation, apoptosis and angiogenesis. PI3K-Akt signaling pathway, IL-17 signaling pathway, TNF signaling pathway were the main pathways.Conclusion The treatment of EM with activating blood circulation and removing blood stasis herbs has the characteristics of multiple components, multiple targets and multiple pathways, which can relieve the pain, inflammation and menstrual disorders symptoms of EM.
