To evaluate the efficacy and safety of Guizhi Fuling Capsules (Pills) combined with levonorgestrel intrauterine system (LIS) in the treatment of patients with adenomyosis.Methods:Randomized controlled trials (RCTs) and clinical trials (CCTs) on the treatment of adenomyosis with Guizhi Fuling Capsules (Pills) and LIS were retrieved from China National Knowledge Infrastructure (CNKI),VIP,China Biology Medicine disc (CBMdisc),PubMed,The Cochrane Library,The Web of Science,Springer,and other databases (from inception to May of 2020).Revman5.3 was employed for Meta-analysis of the extracted data.Results:A total of 10 RCTs and 2 CCTs were screened out,involving 1 206 patients.The Meta-analysis showed that Guizhi Fuling Capsules (Pills) combined with LIS demonstrated higher total effective rate in the treatment of adenomyosis (OR=3.31,95%CI=2.12 to 5.18,P<0.000 01).Moreover,the combination alleviated the dysmenorrhea with decrease in chronic pain grade questionnaire score (MD=-0.46,95%CI=-0.62 to -0.29,P<0.000 01) and Visual Analogue Scale (VAS) score (MD=-1.75,95%CI=-2.01 to -1.49,P<0.000 01) and reduced menstrual blood volume (MD=-15.47,95%CI=-20.20 to -10.73,P<0.000 01),endometrial thickness (MD=-15.47,95%CI=-2.14 to -2.38,P<0.000 01),uterine volume (MD=-16.23,95%CI=-19.45 to -13.02,P<0.000 01),serum follicle-stimulating hormone (FSH) (MD=-1.30,95%CI=-1.86 to -0.74,P<0.000 01),serum luteinizing hormone (LH) (MD=-1.18,95%CI=-1.37 to -1.00,P<0.000 01),serum CA125 (MD=-9.68,95%CI=-12.83 to -6.54,P<0.000 01),and the incidence of adverse reactions (OR=0.53,95%CI=0.29 to 0.94,P=0.03).Conclusion:The combination Guizhi Fuling Capsules (Pills) and LIS is superior to LIS alone in the treatment of adenomyosis,and the incidence of adverse reactions is lower than that of LIS alone.In the future,large-scale samples and high-quality articles should be included to further evaluate the combination. |
