Based on the theory of "Kidney-blood-bone" to explore the mechanism of GH/IGF-1 system in the prevention and treatment of osteoporosis in Qing 'e pill.

Objective: To observe the changes of growth hormone (GH)/insulin-like growth factor- 1(Igf-1) system in blood, kidney and bone tissue of rats, and to explore the preventive and therapeutic effect of Qing 'e pill on osteoporosis due to kidney deficiency and its mechanism, to provide the basis for studying the etiology and pathogenesis of osteoporosis due to kidney deficiency. Methods: The rat osteoporosis model was established by ovariectomy, they were randomly divided into normal group, model group, Western Medicine Group, Jianpi Group, high-dose group, middle-dose group and low-dose group, the levels of serum alkaline phosphatase (ALP), tartrate acid phosphatase (TRACP), growth hormone (GH) and GHR (Ghr) in kidney, bone and blood were determined by Elisa, the contents of insulin-like growth factor-1(Igf-1) and insulin-like growth factor-1 receptor (IGF-1R) were analyzed by SPSS 25.0 software. Results: 1. Compared with the normal group, the contents of TRACP and ALP in serum of the model group were significantly increased, suggesting that the rats developed high-conversion osteoporosis. 2. The levels of serum, bone and renal GHR, Igf-1 and insulin-like growth factor-1 receptor (IGF-1R) in the model group were significantly lower than those in the control group. 3. Compared with the model group, the contents of TRACP and ALP in the high, middle and low dose groups were significantly decreased. 4. Compared with the model group, the contents of GHR, Igf-1 and IGF-1R in blood, bone and kidney tissue of the high, middle and low dose groups were increased. Conclusion: 1. Qing 'e pill can improve the bone metabolism of osteoporosis. 2. Qinge pill may prevent and cure osteoporosis by increasing the contents of GHR, Igf-1 and IGF-1R in blood, bone and kidney.
