摘要 目的:探讨急性脑梗死(ACI)患者血清血管内皮生长因子(VEGF)的变化及其在ACI病理生理过程中的作用。方法:采用双抗体夹心ABC-ELISA法,于发病72 h内、第7 d及第14 d测定病例组(91例ACI患者)的血清VEGF水平,并与对照组(50例健康体检者)比较,同时比较不同卒中亚型的VEGF表达。结果:病例组在发病72 h内、第7 d及第14 d的血清VEGF水平明显高于对照组(P<0.01);大面积梗死组各时点血清VEGF水平高于小面积组(P<0.01);心源性栓塞组血清VEGF水平在第7 d、第14 d高于小动脉闭塞组(P<0.05),但在入院72 h内无显著差异,大动脉粥样硬化组与其它两个亚组无显著差异。VEGF与CRP(r=0.372,P<0.05)、WBC(r=0.647,P<0.01)、NIHSS评分(r=0.448,P<0.05)之间呈正相关,与2周时的神经功能改善程度没有相关性(r=0.193,P>0.05)。结论:ACI患者血清VEGF水平明显增高,可能参与了脑梗死早期的炎症反应、再灌注损伤以及修复病理变化过程,在一定程度上反映了脑梗死缺血缺氧严重程度及预后。
