Expression and clinical significance of VEGF, ENS and MVD in atherosclerosis plaque of femoral artery in patients with atherosclerosis obliterans / 中国综合临床

ABSTRACT

Objective To investigate the relationship between the expressions of VEGF,ENS, MVD and arteriosclerosis (AS) plaque in atherosclerosis obliterans (ASO) patients. Methods Immunohistochemical staining was used to determine the expression of VEGF, ENS and MVD value in the atherosclerosis plaque of ASO patients hospitalized from October 2007 to August 2010 in our hospital (n =30),and the femoral arterials of control were collected from 22 amputation after traumatic injury. Results The expressions of VEGF (2. 24 ±0.31 vs. 1.87 ±0.27,t =3.58),ENS (1.84 ±0.41 vs. 1. 56 ±0. 38, t =2.09) and MVD value (8.79 ±2.46 slip/HP vs. 6. 05 ±1.68 slip/HP, t =3.64) were significantly higher in the AS plaque of ASO patient than control (P <0.01 or P < 0. 05). We found positive correlations between the expression of VEGF, VEGF/ENS with MVD (r = 0. 391, P < 0. 01; r =0. 583, P < 0. 05) , while negative correlation between the expression of ENS with MVD (r=-0. 328,P <0. 05). Conclusion VEGF promotes the angiogenesis in atherosclerosis plaque,while ENS shows opposite effect The comprehensive performance of them is promoting angiogenesis.
