Abstract:
Objective:To explore the relationship between Jiegu pastes and blood biochemical indices and the expression of cal-catonin gene related peptide( CGRP) in the process of fracture healing. Methods: The tibial fracture model of rats was established, and the rats were randomly divided into five groups:the blank control group, model control group, positive control group, Jiegu paste at low dose group ( L, 1 g·ml-1 , calculated by raw materials) and at high dose group ( H, 2 g·ml-1 , calculated by raw materials) with 60 ones in each. The blank control group and the model control group were given 2 ml saline, the positive control group was given 2 ml concentrated dipsacus bone mixture, and Jiegu paste L group and H group was given 2 ml concentrated solution at low concentra-tion and high concentration, respectively, and all the groups were with the following regimen: ig,qd, for 28 days. The blood samples and callus specimens were obtained on the 7th, 14th, 21st and 28th day after fracture. Blood biochemical indices were detected, and HE staining and immunohistochemical staining were performed. Results: Compared with those in the model control group, the serum calcium and phosphorus ion concentration in Jiegu paste H group significantly increased on the 14th and 21st day, and the serum AKP significantly increased on the 14th and 28th day (P<0. 05). The expression of CGRP in Jiegu paste H group was significantly higher than that in the control group (P<0. 05). There were no significant differences between H group and the positive control group (P>0. 05). Conclusion:Jiegu paste can achieve the purpose of promoting fracture healing by improving the activity of serum AKP, in-creasing the concentration of calcium and phosphorus and regulating the activity of neuropeptide CGRP.
