摘要:

目的   探讨CD36单核苷酸多态性(SNPs)与老年动脉粥样硬化性脑梗死(ACI)相关性。方法   选取75岁以上ACI患者121例作为病例组,对照组选取无脑梗死病史体检者217例。采用PCRLDR技术检测CD36 rs1761667、rs9784998两个位点基因型,ELISA法测定血栓素B2。结果    病例组rs9784998基因型、等位基因频率与对照组相比无统计学差异(P>0.05)。rs1761667 AG基因型频率分布在两组间具有统计学差异(χ2=7.03, P<0.01)。Logistic多因素分析和逐步回归分析显示,与其他两种基因型相比,AG基因型均能增加脑梗死的患病风险(P<0.05)。病例组血栓素B2水平较对照组明显升高(P<0.01),但AG基因型人群中血栓素B2水平两组间无统计学差异(P>0.05)。结论   CD36 rs9784998单核苷酸多态性与动脉粥样硬化性脑梗死无统计学相关,rs1761667单核苷酸多态性是老年动脉粥样硬化性脑梗死的遗传危险因素。CD36基因多态性与血栓素B2无统计学相关。

Abstract:

Objective   To explore the relationship between CD36 single nucleotide polymorphisms and atherosclerotic cerebral infarction in elderly patients. Methods   121 patients with atherosclerotic cerebral infarction who were older than 75 years were enrolled into the case group.217 health-examination people who had no cerebral infarction were selected as the control group. PCR-LDR was used to detect the genotype of rs1761667 and rs9784998 which are two locis of CD36. Enzyme linked immunosorbent assay (ELISA) was used for determination of plasma thromboxane B2. Results   There were no significant differences in genotype and allele frequencies of rs9784998 between case and control groups(P>0.05). AG genotype frequency distribution of rs1761667 between the two groups had significant difference (χ2=7.03, P<0.01). Logistic multifactor analysis and stepwise regression analysis showed that, compared to the other two genotypes, AG genotype could increase the risk of cerebral infarction(P<0.05). The levels of plasma thromboxane B2 in case group was significantly higher than in control group(P<0.01), but the thromboxane B2 in patients with AG genotype had no statistical difference between the two groups(P>0.05). Conclusion   rs9784998 is not statistically associated with atherosclerotic cerebral infarction. rs1761667 is a genetic risk factor of atherosclerotic cerebral infarction. CD36 SNPs have no statistical correlation with plasma thromboxane B2.

Key words: Atherosclerotic cerebral infarction; CD36; Single nucleotide polymorphism; Thromboxane B2
