[Network Meta-analysis of Chinese medicine injections in treatment of rheumatoid arthritis].

This study aims to systematically evaluate the efficacy and safety of Chinese medicine injections in the treatment of rheumatoid arthritis. Specifically, randomized controlled trial(RCT) in the treatment of rheumatoid arthritis with Chinese medicine injections was retrieved from PubMed, EMbase, Cochrane Library, Web of Science, Wanfang, CNKI, VIP, and SinoMed(from inception to February 16, 2022). RevMan 5.3 and Stata 15.0 were employed for data analysis. Finally, 53 RCTs, involving 4 280 patients were included. The experimental groups involved the following injections: including Danshen Chuanxiongqin Injection, Tanshinone Ⅱ_A Sodium Sulfonate Injection, Danhong Injection, Dengzhan Xixin Injection, Gugua Extract Injection, Honghua Injection, Lugua Polypeptide Injection, Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection, Shuxuetong Injection, Zhengqing Fengtongning Injection, Compound Danshen Injection, and Xuebijing Injection. The network Meta-analysis showcased the following trends.(1) As for improving total clinical effective rate, the surface under the cumulative ranking curve(SUCRA) followed the order of conventional treatment of western medicine combined with Xuebijing Injection > combined with Gugua Extract Injection > combined with Compound Danshen Injection > combined with Danshen Chuanxiongqin Injection > combined with Honghua Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection > combined with Lugua Polypeptide Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Dengzhan Xixin Injection.(2) As for improving erythrocyte sedimentation rate(ESR), SUCRA followed the order of conventional treatment of western medicine combined with Xuebijing Injection > combined with Shuxuetong Injection > combined with Honghua Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Gugua Extract Injection > combined with Danhong Injection > combined with Lugua Polypeptide Injection > combined with Dengzhan Xixin Injection > combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Danshen Chuanxiongqin Injection > combined with Zhengqing Fengtongning Injection.(3) As for improving rheumatoid factor(RF), SUCRA followed the order of conventional treatment of western medicine combined with Lugua Polypeptide Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Gugua Extract Injection > combined with Danshen Chuanxiongqin Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection > combined with Dengzhan Xixin Injection.(4) As for improving C-reactive protein(CRP), SUCRA followed the order of conventional treatment of western medicine combined with Xuebijing Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Honghua Injection > combined with Danshen Chuanxiongqin Injection > combined with Dengzhan Xixin Injection > combined with Gugua Extract Injection > combined with Lugua Polypeptide Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection.(5) As for alleviating morning stiffness, SUCRA followed the order of conventional treatment of western medicine combined with Shuxuetong Injection > combined with Lugua Polypeptide Injection > combined with Dengzhan Xixin Injection > combined with Xuebijing Injection > combined with Gugua Extract Injection > combined with Zhengqing Fengtongning Injection > combined with Danhong Injection > combined with Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Honghua Injection.(6) As for improving disease activity score(DAS28), SUCRA followed the order of conventional treatment of western medicine combined with Lugua Polypeptide Injection + Tanshinone Ⅱ_A Sodium Sulfonate Injection > combined with Lugua Polypeptide Injection > combined with Zhengqing Fengtongning Injection > combined with Honghua Injection > combined with Gugua Extract Injection > combined with Dengzhan Xixin Injection. The experimental groups had lower incidence of adverse reactions than the control group. The results of network Meta-analysis suggest that on the combination of conventional treatment of western medicine with Chinese medicine injections can improve the efficacy on rheumatoid arthritis. However, in view of the great differences in the quality and number of studies included for different therapies, the SUCRA of Chinese medicine injections need to be further verified with high-quality multi-center, large-sample, randomized double-blind trials.
