Abstract:
ABSTRACT Objective:To explore the mechanism of action of Jiegu Xujin Wan(接骨续筋丸,JGXJW)in promoting fracture healing in rats.Methods:Seventy-two 3-month-old male SD rats were randomly divided into sham-operated group,model group,Jiegu Qili Jiaonang(接骨七厘胶囊,JGQLJN)group and JGXJW group,18 cases in each group.The middle femoral shafts of rats in model group,JGQLJN group and JGXJW group were cut off to build open femoral fracture models,while the surgeries were performed on the rats in sham-operated group to expose their femoral shafts only.Since the 2nd day after the modeling operation,the rats in JGXJW group,JGQLJN group,model group and sham-operated group were intragastric administrated with JGXJW suspension(3 g/kg),JGQLJN suspension(0.52 g/kg)and distilled water respectively,once a day for 21 consecutive days.At 7,14 and 21 days after the beginning of drug intervention,6 rats were randomly selected from each group,and their blood were fetched out from aorta abdominalis.The upper serum was sucked from the blood samples after standing and centrifuging for further inspection.Then the rats were sacrificed and their left femoral shafts were fetched out for making femoral paraffin specimens.The serum contents of calcium(Ca),phosphorus(P)and alkaline phosphatase(ALP)were determined by using Ca,P and ALP assay kit.The morphological changes of bone tissues were observed after hematoxylin-eosin(HE)staining,and the expression of bone morphogenetic protein 2(BMP-2)and vascular endothelial growth factor(VEGF)in bone tissues of broken ends of fractured bone were detected by immunohistochemical method respectively.Results:There was no statistical difference in serum content of Ca between the 4 groups at 7,14 and 21 days after the beginning of drug intervention(1.80+/-1.03,1.88+/-0.80,1.91+/-0.68,1.83+/-0.62 mmol/l,F=0.023,P=0.995; 1.77+/-0.89,1.77+/-0.73,1.88+/-1.18,1.74+/-0.89 mmol/l,F=0.025,P=0.095;

in JGQLJN group compared to JGXJW group(P=0.029).Conclusion:JGXJW can increase the serum contents of P and ALP and promote the expression of BMP-2 and VEGF in bone tissues to promote the osteoblast proliferation,which may be the mechanisms of action for promoting fracture healing in rats.However,its specific mechanism of action needs to be further studied.
