首发时间:2012-11-22
摘要:目的 探讨血管内皮生长因子( VEGF) 936C/T (rs3025039)基因多态性与低分子肝素试验病因分型( TOAST) 中,大动脉粥样硬化性( LAA) 和小动脉闭塞性( SAO) 缺血性卒中 (Ischemic Stroke, IS) 的相关性。方法 应用病例对照分析和聚合酶链反应-限制性片段长度多态性( PCR-RFLP)方法对急性IS患者(发病≤3 d) :LAA 卒中321例,SAO 卒中99 例和456例健康对照组的VEGF 936C/T 等位基因频率和基因型频率与IS之间的关系进行分析。结果IS 组和LAA 组患者中,VEGF基因rs3025039 多态位点TT+CT基因型频率为59.0%,T 等位基因频率为31.8%,分别高于对照组的41.4% 和22.6%,差异有统计学意义(P<0.001)。多因素Logistic 回归分析发现,TT+CT 基因型(OR= 2.39,95% CI : 1. 58~3.66) 是LAA型卒中的独立危险因子。结论与对照组比较,VEGF 936C/T基因多态性位点与IS有关联,T等位基因与LAA型卒中关系更为密切,T等位基因可能是IS的风险等位基因。

Association between 936C/T polymorphisms in vascular endothelial growth factor gene with cerebral infarction subtypes in the Han Chinese Population
Abstract:To investigate the association between vascular endothelial growth factor (VEGF) level and its rs3025039 (936C/T) polymorphism and the Trial of Org 10172 in Acute Stroke Treatment (TOAST) subtypes of ischemic stroke (IS). Methods A total of 420 patients with acute IS (symptom onset ≤3 days) were enrolled. They were divided into either a large-artery atherosclerosis (LAA) stroke group (n=321) or a small artery occlusion (SAO) stroke group (n=99) according to the TOAST classification. The case-control analysis and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFP) methods were used to analyzed the relationship between the VEGF 936C allele and genotype frequencies with IS. Results Among the patients in the LAA and IS groups, the rs3025039 gene polymorphism loci TT+CT genotype frequency was 59.0%, the T allele frequency was 31.8%,which were higher than control group (genotype: 41.4% and T allele 22.6%) (P<0.001). Logistic regression analysis showed that the TT+CT genotype is an independent risk factor for LAA stroke (OR=2.39, 95% CI: 1.58~3.66). Conclusion Compared with control group, the VEGF 936C/T gene polymorphism was associated with IS. T allele had more close correlation with IS of LAA type and T allele might be the risk allele of the IS.
