摘要
目的:探讨血管内皮生长因子(vascular endothelial growth factor,VEGF)、自由基SOD和MDA在急性脑梗死发病中的作用。方法:分别采用双抗体夹心ELISA法、黄嘌呤氧化法和比色法动态测定60例急性脑梗死患者及正常对照者起病后或入组后第1天、3天、7天、14天外周血清VEGF和SOD、MDA水平,分析其关系。结果:脑梗死组各时间点血清VEGF的水平明显高于正常对照组(P<0.01),至病程第7天达高峰,以后逐渐下降,至14天仍维持较高水平,差异有统计学意义(P<0.01);脑梗死组发病第1天及第3天,SOD水平明显低于对照组,MDA水平明显高于对照组(P<0.01),在第7天及14天,两组比较无显著性差异;患者血清VEGF水平在发病第3、14天随着梗死面积增大及病情严重程度而升高,三组比较有显著性差异(P<0.01),而血清SOD和MDA水平只在发病第3天才与梗死面积及病情严重程度有变化(P<0.01)。结论:VEGF、MDA和SOD共同参与脑梗死急性期血管病理损伤过程,VEGF可作为评估急性脑梗死患者病情轻重和预后的客观指标。
