Abstract:
Objective:This study explores the key core targets of Guishenwan in the treatment of thin endometrium and related signaling pathways through the method of network pharmacology，and further uses animal experiments to verify the obtained targets and verify that Guishenwan are effective for thin endometrium. Method:Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform（TCMSP） was used to retrieve the effective chemical components，active component targets and target abbreviations of the eight Chinese medicines in Guishenwan，the GeneCards database and Online Mendelian Inheritance in Man（OMIM）database were used to retrieve thin endometrial related targets gene.Use Wayne software to take the intersection of the drug target of Guishenwan and the disease target of the thin endometrium，and import the intersection target into the STRING database and Cytoscape 3.7.2 software for visual analysis to obtain the "drug-disease" protein protein interaction（PPI） network， then input the intersection target into Enrichr database and DAVID database for gene ontology（GO） enrichment analysis and Kyoto encyclopedia of genes and genomes（KEGG） enrichment analysis. Using the obtained possible core and key targets as the theoretical basis，a thin endometrial model in rats was established. After Guishenwan and estrogen intervention for 21 days，the endometrial thickness of rats was observed by hematoxylin-eosin staining（HE） staining. Western blot and quantitative real time polymerase chain reaction（Real-time PCR） detect the protein and mRNA expression levels of the four core key targets of epidermal growth factor receptor（EGFR），matrix metalloproteinase 9（MMP9），interleukin-1beita（IL-1β） and mitogen activated protein kinase 14（MAPK14）. Result:The Venn software obtained 130 intersection targets in total， imported 130 intersection targets into the STRING database and Cytoscape database，and obtained a protein interaction network diagram including 33 nodes and 107 edges. DAVID 6.8 database for GO analysis. The function annotation analysis involving 167 biological processes（BP），22 cell components（CC），39 molecular functions（MF）. DAVID 6.8 database for KEGG enrichment analysis， and thin endometrium related A total of 34 pathways. Western blot and Real-time PCR were used to analyze the expression results of EGFR，MMP9，IL-1β，MAPK14 protein and genes in the endometrial tissues of the 6 groups of rats. Guishenwan can enhance the expression of EGFR，MMP9，IL-1β，MAPK14 protein and mRNA on the thin endometrium. Conclusion:According to the theoretical analysis of network pharmacology and the results of animal experiments，it is found that Guishenwan can effectively improve the related indicators of thin endometrium，and promote the expression of EGFR，MMP9，IL-1β，MAPK14 protein and genes. The intimal tissue proliferates and improves the symptoms of thin intima.
