摘要
目的探讨细胞间黏附分子1(intercellularadhesionmolecule1,ICAM1)基因多态性与广西地区壮族人群缺血性脑卒中(ischemicstroke,IS)的关系。方法采用聚合酶链反应限制性片段长度多态性和DNA序列测定法检测205例IS及210名对照者ICAM1基因第6外显子K469E多态性,同时采用酶联免疫吸附试验检测IS和对照者血清ICAM1水平。结果IS组ICAM1血清水平显著高于对照组(P<0.01),ICAM1基因K469E基因型频率和等位基因频率在IS组和对照组比较差异有统计学意义(P<0.05),等位基因频率的相对风险分析发现,E等位基因携带者患IS的风险是K等位基因的1.424倍(OR=1.424,95%CI:1.071~1.894),携带E等位基因的IS患者ICAM1血清水平显著高于不携带者[(501.24±139.56)ng/mlvs(475.17±118.35)ng/ml,P<0.01]。结论ICAM1基因K469E多态性与IS的发病具有相关性,E等位基因可能是广西地区壮族人群IS发病的遗传易感基因,携带E等位基因的个体可能通过促进ICAM1的高度表达进而增加IS的发病风险。
