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...
