Objective To provide evidence of the effects of total flavonoids from Rhizoma Drynariae(TFRD)on postmenopausal osteoporosis (PMOP).Methods CNKI, China biomedical database , Chinese Science and Technique Journals Database, Wanfang database, the Cochrane Library, PubMed, and EMBASE had been retrieved by computer to collect data of randomized controlled clinical trials on the effects of Qianggu Capsule(the main component is TFRD) in treatment of PMOP.The retrieval time was from database establishment to November 2017.System evaluation and meta-analysis were performed by RevMan 5.3. Results Six references were included, including a total of 8 researches.In terms of clinical efficiency and improving bone mineral density of femur, Qianggu Capsule combined with conventional treatment was better than conventional treatment, the Meta results were RR=1.50,95% CI(1.04,2.17),P=0.03 and . Compared with the conventional treatment group, the difference was not statistically significant in improving bone mineral density of lumbar spine or hip and calcium, phosphorus, alkaline phosphatase, osteocalcin, and other biochemical indicators in blood. Its side effects included constipation, dry mouth, nausea and gastrointestinal reactions. But after treatment with symptomatic treatment, drug withdrawal was needless. Conclusion There is a lack of strong evidence to support that TFRD can play a fundamental role in PMOP.Although compare with conventional treatment, there is no obvious advantage in improving bone mineral density and calcium, phosphorus, alkaline phosphatase, osteocalcin, and other biochemical indicators in blood, but clinical research evidence shows that it has a certain effect in improving the patient's symptoms, and has good safety. |
