摘要 目的探讨血小板衍生内皮细胞生长因子(PD-ECGF)在颈动脉粥样硬化剥脱术(carotid endarterectomy,CEA)术后再狭窄血管中的表达及其与管腔狭窄程度的相关性。方法 20只新西兰清洁级白兔,随机分为对照组(5只)和实验组(15只),建立兔颈动脉再狭窄模型,取材后行免疫组织化学染色,与对照组相比,观察实验组PD-ECGF的表达,并观察其阳性表达强度与管腔狭窄程度的关系。结果实验组PD-ECGF阳性表达(>2分)13例,阴性(≤2分)2例,对照组阳性表达3例,阴性12例,对比差异有统计学意义(P<0.01);PD-ECGF阳性表达强,其管腔狭窄程度较轻,表达较弱时则相反。结论 PDECGF可能是血管再狭窄形成诸多因素中的一种起保护作用的因子,可促进内皮细胞的迁移,从而抑制血管平滑肌的增殖。
