Participants in the treatment group were treated with Zuogui pill or Yougui pill TCM formula granule, while the control group received placebo. Primary outcomes are the lumbar spine on bone mineral density(BMD)(L1-4) and femoral BMD. Secondary outcomes include pain intensity,health-related quality of life(HRQo L), bone turnover markers and safety.RESULTS: Totally 200 patients were enrolled from December 2014 to April 2016 from four hospitals.There were no statistically significant differences between the two groups at baseline(P > 0.05) and it was good to comparability. Statistically significant differences between the two groups were observed for the lumbar BMD(L1-4), pain VAS scores and HRQo L at six months and twelve months and femoral BMD at twelve months(P < 0.05), but no significant differences for femoral BMD and bone turnover markers at six months(P > 0.05). Moreover, significant difference was observed at different time before and after treatment in terms of lumbar spine(L1-4) BMD, femoral BMD, pain VAS scores and health-related quality of life, and there was an crossover effect between the time and groups before and after treatment. In additional, in the treatment group, 8 patients lost to follow-up and 3 patients had adverse events(AEs) and in the control group, 10 patients lost to follow-up and 2 patients had AEs. No remarkable differences were observed between the two groups with regard to AEs, lost rate and safety(P > 0.05).CONCLUSION: Zuogui pill or Yougui pill could improve BMD, ease pain, relieve Kidney deficiencysyndrome, improve the quality of life osteoporosis patients, inhibit bone conversion and regulate the coupling balance of bone formation and bone resorption, but long-term efficacy should be confirmed by a longer term follow-up and larger of samples clinical randomized controlled trials.展开更多
