Objectives: To explore and summarize the beneficial effects of a traditional Chinese medicine preparation, Tripterygium glycosides tablets (TGT), in rheumatoid arthritis (RA) animal models of neovascularization, and to provide a reference for future clinical applications and research on its pharmacologic mechanism. Methods: We searched the databases PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure, VIP, Wan Fang and SinoMed (China Biomedical Document Service System) to identify studies of TGT with outcome indicators of angiogenesis-related factors that were published before April 2020. Subgroup analysis and meta-regression were performed for dosage and duration of TGT. Statistical tests and subgroup analysis were conducted using RevMan 5.3, and meta-regression and sensitivity analysis were conducted using STATA/SE 15.0. Results: Fourteen studies of TGT in RA rats were included in this analysis. Treatment with TGT significantly reduces synovial microvessel density and the expression of vascular endothelial growth factor (VEGF), VEGF receptor 2, hypoxia inducible factor α, c-Fos, c-Jun, angiopoietin-1 and angiopoietin-2 compared with control groups (P |
