Efficacy and mechanism of nourishing yin and purging fire therapy for central precocious puberty based on meta-analysis and network pharmacology
Abstract
BACKGROUND: Central precocious puberty (CPP) is due to the early activation of the hypothalamus-pituitary-gonadal axis, and its incidence is on the rise. A number of studies have shown that nourishing yin and purging fire (NYPF) therapy can be beneficial for CPP. Therefore, we conducted this review to investigate the efficacy, safety, and mechanism of NYPF therapy for CPP.
METHODS: Electronic databases including PubMed, the Cochrane Library, Web of Science, EMBASE, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wan-fang Database, and China Scientific Technical Journals Database and 2 platforms including Clinical Trials and Chinese Clinical Trial Registry were searched for randomized controlled trials of NYPF therapy for CPP. A meta-analysis was conducted using RevMan 5.3 and Stata 17.0 software. The core herb pair of NYPF was identified by data mining using IBM SPSS Modeler 18.0 software. The active ingredients and targets of the core herb pair were obtained through the TCMSP database. The main targets of CPP were acquired form the GeneCards, Disgenet and TTD databases. A protein-protein interaction network was carried out to select the core genes by using STRING platform and Cytoscape 3.7.2 software. Metascape platform was used to conduct gene ontology (GO) and KEGG enrichment analysis. The results were verified utilizing molecular docking.
RESULTS: A total of 23 studies were included. Meta-analysis shows the NYPF therapy could…
