Abstract:
OBJECTIVE:To study the effects of new Xianling gubao capsule on fracture healing in rats,and to provide reference for seeking new formula of"to reduce stockpiles and increase efficiency(to reduce stockpiles and constant efficiency)".METHODS:Rats were randomly divided into sham operation group(distilled water),model group(distilled water),Xianling gubao capsule group (350 mg/kg),new Xianling gubao capsule low-dose,medium-dose and high-dose groups (53,105,210 mg/kg),with 14 rats in each group. Except for sham operation group,right middle femur fracture model was established under the anesthetic state. Rats were given relevant medicine 10 mL/kg intragastrically after woken,once a day,for consecutive 4 weeks.After last administration,body weights of rats were determined;the formation of callus and histopathological changes in fracture were observed;biomechanics of fracture side(fracture stress and bone crushing force)was measured. The levels of inflammatory factors (TNF-α ,IL-1 β) in serum were detected by ELISA. RESULTS:Compared with sham operation group,body weight,fracture stress and bone crushing force of fracture side were decreased significantly(P<0.05 or P<0.01),while the serum levels of TNF-α and IL-1 β were increased significantly(P<0.01). In model group,the scab was visible around the fracture,and the trabecular bone was not mature and arranged in confusion. Compared with model group,body weights of rats were increased significantly in new Xianling gubao capsule high-dose group and Xianling gubao capsule group (P<0.05);fracture stress of fracture side were increased significantly in new Xianling gubao capsule medium-dose and high-dose groups and Xianling gubao capsule group(P<0.05 or P<0.01). The serum levels of TNF-α and IL-1β were decreased significantly(P<0.01). There was no statistical significance in above indexes among new Xianling gubao capsule groups and Xianling gubao capsule group(P>0.05).The area of the callus in each group was smaller;the fracture line became blurred;the fracture trace disappeared and the number of bone trabeculae increased. The cortical layer was thickened,and a large number of capillary implants were found in the bone marrow cavity. CONCLUSIONS:New Xianling gubao capsule has a significant role in promoting fracture healing,and can effectively improve the strength of bone biomechanics and inhibit the inflammatory reaction.
