Yangxin Decoction combined acupuncture on blood lipid metabolism in Qi Deficiency and Blood Stasis type of Chest Bi-Syndrome: A protocol of systematic review

BACKGROUND: In recent years, clinical studies about Yangxin Decoction combined acupuncture (YXDA) for the treatment of Qi Deficiency and Blood Stasis type of Chest Bi-Syndrome (CBS-QDBS) has been increased, but the results are different. The aim of this study is to investigate the effect of YXDA on blood lipid metabolism (BLMB) in patients with CBS-QDBS. METHODS: We will collect any randomized controlled trials that assess the effect of YXDA on BLMB in CBS-QDBS from PUBMED, EMBASE, Cochrane Library, PsycINFO, CINAHL, Allied and Complementary Medicine Database, and China National Knowledge Infrastructure. All of these databases will be searched from their initial time to the present. All language limitation will be imposed. Literature selection, information collection, and risk of bias assessment will be performed independently by two authors, respectively. All data analysis will be undertaken using RevMan 5.3 Software. RESULTS: This study will summarize the systematic nature of the literature search and its methods for assessing study quality and analyzing all relevant outcome data. Considering the inconsistent results, this study will improve the existing evidence on the effect of YXDA on BLMB in CBS-QDBS. CONCLUSION: The findings of this study will present the latest evidence of YXDA on BLMB in patients with CBS-QDBS. Study registration: INPLASY202070047.
