Abstract: BACKGROUND: Tanshinone IIA is one of the most abundant fat-soluble components isolated from Radix Salvia miltiorrhiza, which protects the heart and nerves, and exerts anti-cancer and antibacterial effects. There is no systematic study on the mechanism of tanshinone IIA in the treatment of vascular injury.
OBJECTIVE: To explore the mechanism of tanshinone IIA in treating vascular system injury by bioinformatics and molecular docking. 
METHODS: In this study, the oral bioavailability and drug-likeness of tanshinone IIA were searched by TCMSP database, and GSE85871 gene chip was downloaded from GEO database, and the differentially expressed genes were analyzed by R to obtain the potential target of tanshinone IIA. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of potential targets were carried out through DAVID6.8 database. CTD database was used to mine diseases related to tanshinone IIA, and Cytoscape was used to construct multi-target, multi-channel and multi-disease visualization network of tanshinone IIA. AutoDock Vina was used to verify the docking of proteins and small molecules. 
RESULTS AND CONCLUSION: Tanshinone IIA had an oral bioavailability value of 49.89% and a drug-likeness value of 0.4, indicating a good drug effect. A total of 132 potential targets were screened out. Among the above targets and protein-protein interaction networks, they were mainly manifested in gene co-expression and physical interaction. The biological processes and pathways of potential targets were mainly enriched in ovarian steroid production, cell cycle and steroid hormone biosynthesis, etc. Tanshinone IIA was related to the treatments for breast tumors, hypertension, atherosclerosis, glioma, vascular system damage, left ventricular hypertrophy, leukemia, and hearing loss. The molecular docking results show that tanshinone IIA had good binding activity with vascular system damage-related proteins, such as heme oxygenase 1 and secreted phosphoprotein 1. With the help of bioinformatics methods and molecular docking technology, the possible molecular mechanism and biological process of tanshinone IIA in the treatment of vascular system damage can be systematically analyzed, which lays the idea and foundation for further research.
