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.
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.

Change of VAS pain score of low back
Draw a straight line with a length of 10 cm on the white paper and mark "painless" and "severe pain" on both ends respectively to form VAS. The patient makes a mark on the straight line according to the degree of pain he feels. The distance from the starting point to the mark is the quantified degree of pain. Painless is represented by 0; 1-3 points represent mild pain; 4-6 points represent moderate pain, which is strong but tolerable; 7-10 points represent severe pain, gradually reaching intolerable level, which is severe pain.
Time frame: Change from baseline VAS score at 2 weeks.

Change of Traditional Chinese medicine (TCM) syndrome score
According to the《expert consensus on the prevention and treatment of primary osteoporosis with reference to traditional Chinese medicine (2020)》, the quantitative evaluation table of TCM syndrome differentiation for osteoporosis with Kidney Yang Deficiency syndrome was formulated to evaluate the symptoms. Symptoms include primary and secondary symptoms, the primary symptoms were low back pain and soreness and weakness, the secondary symptoms include restricted movement of the lumbar spine，fear of cold and like to be warm，degree of frequency of urination. The primary symptom score was 0 (absent), 2 (mild), 4 (moderate), or 6 (marked)，the secondary symptom score was 0 (absent), 1 (mild), 2 (moderate), or 3 (marked).The obtained scores were summed to calculate the total score.

Change of 12-Item Short Form Survey (SF-12) score
The 12-Item Short Form Survey have 12 items and 8 dimensions, which are overall health, Physical Functioning, Role-Physical, Bodily Pain, Vitality, Social Functioning, Role-Emotional and Mental Health. The first four dimensions belong to the level of Physical Component Summary, and the last four dimensions belong to the level of Mental Component Summary. Each item was scored according to the corresponding options to evaluate the impact of health on an individual's everyday life. The highest score of item 2 and 3 is 3, and the lowest score is 1. The highest score of the other ten items is 5, and the lowest score is 1. The obtained scores were summed to calculate the total score to evaluate the changes of patients' quality of life.The higher the score, the better the quality of life.
Time frame: Change from baseline SF-12 score at 1 month.

Changes of serum bone metabolic indexes
Serum level of Beta-CrossLaps (β-CTX) in ng/mL, N-terminal propeptide of type I procollagen (P1NP) in ng/mL，which are determined by Electrochemiluminescence Method.The normal reference ranges of serum P1NP and β-CTX are 16.3\~78.2 ng/mL and 0.114\~0.628ng/mL, respectively.In case of abnormal conditions,the higher the β-CTX, the more serious the bone resorption.The lower the P1NP, the less bone formation and the worse the bone condition.
Time frame: Change from baseline bone metabolism index at 3 months.
Changes of serum ALP
Serum level of Alkaline phosphatase (ALP) in U/L, which is determined by automatic biochemical analysis.The normal value is 40-150 U/L.When it is lower than the normal value, it indicates that bone formation is reduced.
Time frame: Change from baseline ALP at 3 months.
Changes of serum BGP
Serum level of bone glaprotein (BGP) in μg/L, which is determined by automatic biochemical analysis.The normal value is 4.8\~10.2 μg/L.When it is lower than the normal value, it indicates that bone formation is reduced.
Time frame: Change from baseline BGP at 3 months.
Changes of serum 25OHD
Serum level of 25-hydroxy vitamin D (25OHD) in nmol/ml，which is determined by Electrochemiluminescence Method. Its value ≥ 30 nmol/L is normal，it may appear osteoporosis if below this value.
Time frame: Change from baseline 25OHD at 3 months.
Therapeutic mechanism
Serum level of EphrinB2, EphB4, Runx2 and VEGF in μg/mL，which is determined by enzyme linked immunosorbent assay（ELISA）.The higher the value, the better the bone condition. So as to verify the mechanism of Bugu Shengsui decoction.
Time frame: Change from baseline at 3 months.
