Comparison of efficacy and safety of complementary and alternative therapies for scapulohumeral periarthritis: A protocol for Bayesian network meta-analysis.

BACKGROUND: Scapulohumeral periarthritis is a disease with high incidence and great pain. The current western treatments with many side effects, poor efficacy cannot fundamentally solve the problem. Complementary and alternative therapies have played an excellent role in the treatment of scapulohumeral periarthritis. However, it is not clear which complementary and alternative therapy is more effective. Therefore, we propose a protocol to compare the efficacy and safety of various complementary and alternative therapies through network meta-analysis (NMA) to provide choice guidance for the therapy. METHODS: A comprehensive search will be conducted for randomized controlled trials of complementary and alternative therapy for scapulohumeral periarthritis as well as ongoing trials. The time limit is from the establishment of the database until January 2021. Literature and data extraction were completed independently by two researchers. Through pairwise comparison and meta-analysis of Bayesian NMA, all the evidences are evaluated comprehensively. STATA16.0 and WinBUGS1.4.3 software will be used for data processing and analysis, and recommendation evaluation will be used to develop and assess grades to classify the quality of NMA evidence. RESULTS: Through the analysis, we will obtain the ranking of the efficacy and safety of different complementary and alternative therapies in the treatment of scapulohumeral periarthritis, in order to provide reference for clinical selection of treatment methods. CONCLUSION: Complementary and alternative therapies of scapulohumeral periarthritis plays a positive role in improving the symptoms of scapulohumeral periarthritis. This study can provide evidence support for clinicians and patients.International Platform of Registered Systematic Review and Meta-Analysis Protocols registration number: INPLASY202140044.

[Analgesic and anti-inflammatory effects of balance acupuncture on experimental scapulohumeral periarthritis in rabbits].

OBJECTIVE: To investigate therapeutic effects of balance acupuncture on scapulohumeral periarthritis (SP)and the mechanisms. METHODS: Thirty male New Zealand rabbits were randomly divided into a blank group (group B), a model group (group M) and a balance acupuncture group (group BA) with 10 rabbits in each group. SP model was established by using persistent mechanical strain and ice compress. Balance acupuncture at "Jiantong" point was applied in the animals in group BA, but not in the rabbits of the other two groups. Joint movement and pathological changes in tissues around the affected shoulder joint were observed, and interleukin-1beta (IL-1beta), 5-hydroxytryptamine (5-HT) in plasma and the affected surrounding tissues, and DNA contents in tendon of supraspinatus muscle were measured. RESULTS: The content of plasma 5-HT in group BA [(18.16 +/- 4.44) ng/mL] was significantly lower than that in group M [(23.28 +/- 5.89) ng/mL] (P < 0.05), but without obvious difference in IL-1beta content between the two groups (P > 0.05). Compared with group M, the contents of IL-1beta, 5-HT in affected surrounding tissues, and DNA expression in tendon of supraspinatus muscle were significantly lowered to va rious extent in group BA (P < 0.01, P < 0.05). CONCLUSION: Balance acupuncture can effectively improve local and systemic pathological situation induced by SP by way of reducing pain-producing factors, inflammatory factors and DNA expression to alleviate local organization and adhesions in rabbits with experimental SP.
