METHODS： Participants aged 55 to 75 with osteoporosis and Kidney deficiency in Traditional Chi-nese Medicine （TCM） will be included and randomly allocated into two groups： treatment group and control group. Participants in the treatment group were treated with Zuogui pill or Yougui pill TCM formula granule, while the control group received pla- cebo. 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 （HRQoL）, bone turn- over 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 signifi- cant differences between the two groups were ob- served for the lumbar BMD （L1-4）, pain VAS scores and HRQoL 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）. More- over, significant difference was observed at differ- ent time before and after treatment in terms of lum- bar 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 be- fore and after treatment. In additional, in the treat- ment 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
