Objective. Using network pharmacology research methods to explore the healing mechanism of American cockroach extract to accelerate wound healing after diabetic anal fistula surgery. Method. The main chemical constituents of extracts from Periplaneta americana were collected by literature retrieval. Chemical composition and targets related to diabetic anal fistula wound could be predicted based on PubChem, Swiss Target Prediction, OMIM, and GeneCards databases, and the putative targets of Periplaneta americana extraction (PAE) for diabetic anal fistula wound were obtained by Venn diagram. These common targets were predicted using the String database for protein-protein interaction (PPI) network and then screening key genes through Cytohubba. Meanwhile, the above targets were analyzed using the DAVID database for gene ontology (GO) enrichment analyses and the Kyoto Encyclopedia of Genes and Genomes (KEGG) path enrichment analyses. Results. A total of 12 chemical components of PAE were obtained by literature retrieval, and 61 therapeutic targets that may accelerate the healing of diabetic anal fistula wounds were predicted by the database. According to PPI network analysis, PAE accelerates wound healing after diabetic anal fistula surgery which may be related to proteins such as AKT1, VEGFA, EGFR, CASP3, STAT3, MAPK1, TNF, JUN, ESR1, and MMP9. GO analysis results show that targets of PAE to promote wound healing were mainly involved in biological processes such as cell proliferation, macrophage differentiation, angiogenesis, and response to hypoxia. KEGG analysis showed that the target genes were mainly concentrated in the PI3K-Akt signaling pathway, HIF-1 signaling pathway, and estrogen signaling pathway. Conclusion. Periplaneta americana extract regulates multiple targets and multiple pathways to promote wound healing after diabetic anal fistula surgery. PI3K-Akt signaling pathway, HIF-1 signaling pathway, and sex hormone signaling pathway may be key pathways in the process of Periplaneta americana extract promoting wound healing.
