摘要
目的探讨血小板白细胞聚集体在缺血性脑梗死中的变化以及与P-选择素基因S290N和P-选择素糖蛋白配体-1基因M62I多态性的关系。方法选取58例缺血性脑梗死患者作为病例组,20例正常人群作为对照组。病例组分为大动脉粥样硬化性脑梗死(LAA)19例,小动脉闭塞性脑梗死(SAO)39例。运用流式细胞技术检测所有受试者的血小板白细胞聚集体(PLA)、血小板单核细胞聚集体(PMA)、血小板淋巴细胞聚集体(PLy A)和血小板中性粒细胞聚集体(PNA)水平。并运用基因测序方法检测P-选择素基因S290N和P-选择素糖蛋白配体-1基因M62I多态性。结果 PMA%在病例组与对照组、LAA与对照组、SAO与对照组间差异有统计学意义(P=0.000,P=0.018,P=0.000)。PNA%在病例组与对照组、LAA与对照组间差异有统计学意义(P=0.045,P=0.002)。PNA%在LAA组SELP基因S290N位点SS和SN基因型间差异有统计学意义(P=0.008)。PLA%在LAA组PSGL-1基因M62I位点MM、MI和Ⅱ基因型间差异有统计学意义(P=0.046)。结论 PMA和PNA与缺血性脑梗死发病有关,SELP基因S290N位点SN基因型以及PSGL-1基因M62I位点MM基因型会增加LAA发生风险。
