Methods: The research identified the main active components and targets of Li’s Jiegu San through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), literature reports, and Swiss Target Prediction. Fracture-related targets were collected from the GeneCards database. Using the String database and Cytoscape 3.7.2 software, we constructed a protein-protein interaction (PPI) network and identified core targets. The study then established a “Li’s Jiegu San-Active Components-Fracture-Targets” network, performing Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis on the potential core targets. Animal experiments further assessed the therapeutic effects of Li’s Jiegu San on fractures with validation of specific targets. Results: The study identified 20 active components of Li’s Jiegu San and 514 corresponding targets. Additionally, 5264 fracture-related targets were collected, with 306 overlapping targets. The core targets for Li’s Jiegu San in treating fractures include tumor protein p53 (TP53), serine/threonine protein kinase AKT (AKT1), activator protein 1 (JUN), interleukin 6 (IL6), epidermal growth factor receptor (EGFR), and tumor necrosis factor (TNF). Pathway enrichment analysis highlighted pathways in cancer, lipid and atherosclerosis, chemical carcinogenesis-receptor activation, AGE-RAGE signaling pathway in diabetic complications, MAPK signaling pathway, and small cell lung cancer as closely related to the therapeutic effects of Li’s Jiegu San on fractures. Conclusion: This study provides a preliminary basis for understanding the mechanism of Li’s Jiegu San in treating fractures through network pharmacology analysis offering valuable insights for its clinical application.展开更多
