Abstract:
Objective To investigate the relationship between the Apolipoprotein(Apo)A5-1131T>C polymorphism and strokes.Methods Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)and polyacrylamide gel eletrophoresis(PAGE)wefe used to analyze the genotypic polymorphism in 327 patients with stroke(including 194 cerebral infarction patients and 133 cerebral hemorrhage patients)and 311 healthy controls.The levels of serum lipids profiles were also measuredby enzymatic methods. Results The frequency of the-1131C allele in cerebral infarction patients was significantly higher than that of the control group(44.1% vs 32.3%,P<0.05),but there was not statisticai difference between cerebral hemorrhage patients and controls on the-1131C allele frequeney(35.4%vs 32.3%,P>0.05).Compared with the noncamers,the C carriers also had a higher triglyceride(TG)levels in stroke group[(1.45±0.77)vs(1.69±1.06)mmol/L,P<0.05],but the total cholesterol(TC),high density lipoprotein cholesterol(HDL-C)and low density lipoprotein cholesterol (LDL-C)levels did not show statistical differences in various genotypes(P>0.05).Unadjusted Logistic regression analysis indicated that TC+CC genotype of A5-1131T>C was significantly associated with the presence of cerebral infarction,but not with hemorrhage stroke.Logistic regression analysis adjustedfor BMI,presence of hypertension or diabetes and HDL-C levels revealed that TC+CC genotype was an independent risk factor for cerebralinfarction(OR=1.932,95%CI:1.057-3.532,P=0.032). Conclusion The ApoA5-1131C allele frequency of the patients with cerebral infarction is significantly higher than controls.ApoA5-1131T>C polymorphism has a significant influence on serum TG levels.The ApoA5-1131T>C variant is associated with an increased susceptibility for ischemic stroke.
