Abstract:
Objective To explore the role and efficacy of VEGF and HGF gene adenovirus vector in promoting angiogenesis in ischemic tissue.Methods 84 Kunming mice were randomly divided into sham group,control group,VEGF group,HGF group and VEGF+HGF group,and the left lower limb ischemia model was established.The blood supply of ischemic tissue was observed by rheometer,and the expression levels of VEGF and HGF in each group were detected by Western Blot and ELISA.Immunohistochemical staining was used to detect angiogenesis(CD31,SMA)in ischemic tissues.Safety was assessed by side effects during treatment in mice.Results After the successful modeling,the blood flow velocity of the left lower limb in each group decreased significantly.On the 7th day after operation,the blood flow of the left lower limb in each group was significantly better than that on the 0th day after operation(P<0.05),and the blood flow of the left lower limb in Ad-VEGF-HGF group was significantly better than that in other groups(P<0.05).On the 28th day after operation,the blood flow of the left lower limb in Ad-VEGF-HGF group gradually stabilized,the blood flow in Ad-VEGF-HGF group was significantly better than that in other groups,and both VEGF group and HGF group were significantly better than the control group(P<0.05).On the 7th,14th,and 28th days following surgery,HGF and VEGF protein levels in the Ad-HGF,Ad-VEGF,and Ad-VEGF-HGF groups were substantially greater than those in the control group(P<0.05).The expression level in the Ad-VEGF-HGF group peaked on the 14th day(all P<0.001)and subsequently declined to preoperative levels on the 28th day after operation.Conclusion Ad-VEGF-HGF gene injection can effectively boost VEGF and HGF protein expression and rapidly reach the relative peak level,encour-aging angiogenesis after lower limb ischemia,increasing blood flow,and improving lower limb circulation.
