摘　　要：目的采用网络药理学和分子对接技术探索脑血疏口服液治疗缺血性卒中的药效物质基础与潜在作用机制。方法基于脑血疏口服液与缺血性卒中的共同靶点构建“单味药-活性成分-作用靶点”网络;通过String数据库构建蛋白互作(PPI)网络;Metascape数据库进行GO功能和KEGG通路注释与富集分析;分子对接分析预测关键的活性成分与靶点的结合互作。结果“单味药-活性成分-作用靶点”网络中获得脑血疏口服液治疗缺血性卒中的可能活性成分29个,作用靶点67个,其中关键活性成分包括山柰酚、β-胡萝卜苷、胡萝卜苷等;PPI网络分析获得AKT1、PTGS2、EGFR、SRC等关键靶点,其中山柰酚与以上四个关键靶点均有较高的亲和力;脑血疏口服液治疗缺血性卒中的机制可能主要涉及激酶活性、炎症反应、氧化应激应答、免疫系统过程等多种分子功能和生物过程,以及EGFR酪氨酸激酶抑制剂抗性、PI3KAkt信号通路等165个通路。结论脑血疏口服液通过多成分、多靶点、多通路和功能的复杂网络调控炎症反应、血管损伤、神经元损伤或凋亡及脑损伤等防治缺血性卒中,为其后续深入药理学研究奠定了基础。Objective To explore the pharmacodynamic material basis and potential mechanism of Naoxueshu oral liquid in the treatment of ischemic stroke by network pharmacology and molecular docking technology.Methods Based on the common target of Naoxueshu oral liquid and ischemic stroke,the network of"single drugactive ingredienttarget"was constructed.The protein interaction(PPI)network was constructed by String database.Metascape database was used for GO function and KEGG pathway annotation and enrichment analysis.Molecular docking analysis was used to predict the binding interactions between key active ingredients and targets.Results In the"single drugactive ingredienttarget"network,29 possible active ingredients and 67 targets of Naoxueshu Oral Liquid in the treatment of ischemic stroke were obtained,among which the key active ingredients included kaempferol,β-daucosterol,daucosterol.The key targets such as AKT1,PTGS2,EGFR,and SRC were obtained by PPI network analysis,among which kaempferol had high affinity with the above four key targets.The mechanism of Naoxueshu oral liquid in the treatment of ischemic stroke may mainly involve a variety of molecular functions and biological processes such as kinase activity,inflammatory response,oxidative stress response,immune system processes,as well as 165 pathways such as EG-FR tyrosine kinase inhibitor resistance and PI3KAkt signaling pathway.Conclusion Naoxueshu oral liquid regulates inflammation,vascular injury,neuronal injury or apoptosis and brain injury through a complex network of multicomponents,multitargets,multipathways and functions to prevent and treat ischemic stroke,laying a foundation for further pharmacological research.
