Meta-analysis on the treatment of diabetic retinopathy by Yiqi Yangyin Huoxue method / 国际中医中药杂志

ABSTRACT

Objective:To systematically evaluate the clinical efficacy of Yiqi Yangyin Huoxue method for the treatment of diabetic retinopathy (DR).Methods:Clinical research literature about Yiqi Yangyin Huoxue method for the treatment of DR was retrieved from China Biomedical Literature Database (CBM), VIP information Chinese Periodical Service Platform (VIP), China National Knowledge Infrastructure (CNKI), Wanfang data, Cochrane Library and PubMed database from the establishment of the databases to December 31, 2021. RevMan5.3 software was used for meta-analysis.Results:A total of 18 articles were included, with a total of 1 487 patients. The results of meta-analysis showed that Yiqi Yangyin Huoxue method for the treatment of DR had curative effect advantages in improving the total clinical effective rate [ RR=1.31, 95% CI (1.21,1.41), P<0.001], the vision [ MD=0.12, 95% CI (0.07, 0.17), P<0.001], the level of whole blood reduced viscosity low shear [ MD=-2.80, 95% CI (-3.76, -1.84), P<0.001], the level of whole blood reduced viscosity high shear [ MD=-0.69, 95% CI (-1.15, -0.24), P=0.003], and plasma viscosity [ MD=-0.31, 95% CI (-0.51, -0.12), P=0.002], decreasing serum vascular endothelial growth factor [ SMD=-1.04, 95% CI (-1.26, -0.81), P<0.001], increasing TCM symptom score [ MD=-3.79, 95% CI (-6.16,-1.42), P=0.002], reducing the level of tumor necrosis factor-α [ SMD=-2.53, 95% CI (-3.55, -1.50), P<0.001] which were better than that of pure Western medicine ( P<0.05). Conclusion:The application of Yiqi Yangyin Huoxue method for the treatment of DR can improve vision, hemorheology and TCM symptoms, improve the total clinical response rate, and reduce the levels of VEGF and TNF-α, with high clinical safety.
