About

The purpose of this study is to evaluate the efficacy and possible mechanism of traditional Chinese medicine in the treatment of primary osteoporosis (Kidney Yang Deficiency Syndrome).It is a randomized, placebo-controlled trial.

Full description

The subjects are selected according to the inclusion criteria and exclusion criteria. Using the network random system, 120 subjects who meet the research criteria are randomly divided into control group and experimental group, with 60 cases in each group. Patients in treatment group take the granule of traditional Chinese medicine prescription, while the control group take simulate granule of the prescription. Both two groups are under symptomatic treatment. Twice a day, in the morning and evening, 30 minutes after meals.The experimental drugs were provided by the pharmacy department of Wangjing hospital, Chinese Academy of traditional Chinese medicine, and the course of treatment was 3 months.The observation time points were before treatment, 2 weeks after treatment, 1 month after treatment and 3 months after treatment. Visual Analogue Score (VAS), Traditional Chinese Medicine（TCM）syndrome score, SF-12 scale and bone metabolism index were used as observation indexes.At the same time, it is planned to determine EphrinB2, EphB4, Runx2 and VEGF in serum by ELISA.

Tele-medicine and information management system is established to help achieve follow-up interviews.Random numbers are generated by SAS 9.4 software. The subjects, caregivers, investigators and outcomes assessors in this study are all blinded.

Enrollment: 120 estimated patients

Ages: 45 to 80 years old

Shedding Standard:

2. Loss of follow-up;
