目的 基于网络药理学的方法研究头花蓼对幽门螺杆菌胃炎以及胃癌的药理学机制，其中槲皮素、没食子酸和槲皮苷是头花蓼的主要活性成分。方法 通过PubChem、STITCH、SEA等8个数据库获取相关数据，并使用Cytoscape软件绘制蛋白-蛋白相互作用及头花蓼-化合物-预测靶点网络图。利用DAVID数据库对相关靶点进行GO和KEGG的富集分析，并应用AutoDock软件进行分子对接，以分析hub基因与其对应小分子的结合能。结果 网络药理学分析结果表明头花蓼对幽门螺杆菌胃炎以及胃癌的作用靶点共有27个，其中degree值前6的核心靶点和其相对应的化合物分子对接的结合能均小于0，且80%的最低结合能结果≤-5.0 kJ/mol。GO和KEGG的富集结果表明头花蓼可以调控炎症反应、细胞凋亡信号通路、TNF信号通路等生物学过程，能通过影响受体复合物、蛋白质异二聚体活性发挥作用。结论 头花蓼多靶点、多途径地作用于幽门螺杆菌胃炎以及胃癌，为头花蓼老药新用提供了新的依据。     

Mechanism of Polygonum capitatum in treatment of Helicobacter Pylori associated gastritis by network pharmacology,microarray data analysis and molecular docking北大核心CSCD

Aim To explore the mechanism of Polygonum capitatum(PC)in the treatment of Helicobacter Pylori associated gastritis(HAG). Methods The databases were used to identify the target of PC active compounds and HAG-related genes,and the intersection was taken to obtain the potential targets of PC treatment of HAG. The interaction network diagram of “drug-active compound-target-disease” and the protein-protein interaction(PPI)network of potential target protein interaction in HAG treated by PC were constructed by software Cytoscape 3.6.0. The important nodes in the network were screened by several topological indexes,and the GO and KEGG enrichment were analyzed by STRING database to obtain the potential signaling pathway of PC in the treatment of HAG. The binding ability of PC active components with key target proteins was observed by molecular docking method. On this basis,the related targets of PC in the treatment of HAG were verified in vivo and in vitro experiments. Results The PC active compounds and targets were identified through the database,and the “drug-active compound-target-disease” network diagram and the PPI network of potential target proteins were constructed. Combined with several topological indexes,the PPI network of potential target-protein interaction was analyzed,and 52 hub genes were screened. Further bioinformatics analysis and high-throughput sequencing revealed that PC exerted an effect on HAG through the Akt/NF-κB/NLRP3 pathway. Based on this,it was found that PC could reduce IL-18 and IL-1β in HAG GES-1 cells and HAG SD rats,up-regulate Akt and its phosphorylation level and reduce NF-κB expression,inhibit the activation of NLRP3 inflammatory body,so as to improve HAG inflammatory response. Conclusions PC could exert a therapeutic effect on HAG by activating Akt and its phosphorylation level,and inhibiting the expression of NF-κB and NLRP3 inflammasome related factors. This study provides a theoretical basis for explaining the mechanism of PC in the treatment of HAG. © 2023 Publication Centre of Anhui Medical University. All rights reserved.
