Abstract:
Objective To investigate the association between thromboxane A2 receptor(TXA2R)gene C795T, T924C,G1686A,rs2271875,rs768963 polymorphisms and aspirin resistance(AR)in Chinese Han population. Methods 168 in-patients with cerebral infarction who had been given aspirin from Zhejiang Provincial Taizhou Central Hospital from October 2009 to May 2013 were enrolled. The platelet aggregation rate was conducted by optical method. The inspections of triglyceride(TG),total cholesterol(TC),high density lipoprotein cholesterol(HDL-C) and low density lipoprotein cholesterol(LDL-C)were conducted by enzymatic colorimetry,whereas blood glucose was tested by hexokinase method. The genotypes of three exons loci C795T,T924C,G1686A and two promoters loci rs2271875,rs768963 polymorphisms in TXA2R gene were detected by the polymerase chain reaction-ligase detection reaction(PCR-LDR)technique. The patients were divided into aspirin sensitive group(AS group,139 cases) and AR group(39 cases)according to the aspirin sensitive degree. The differences between two groups in age, smoking,serum TG,TC,HDL-C,LDL-C,concentration of blood glucose and blood pressure(systolic pressure, diastolic pressure)were compared,and in the mean time,the differences between two groups of TXA2R C795T, T924C,G1686A,rs2271875,rs768963 genotype distribution were also compared. Results AR group had higher incidences of cigarette smoking〔89.7%(35/39)vs. 69.8%(90/129)〕and high blood sugar(mmol/L:8.086±2.785 vs 5.631±1.662,P<0.05 and P<0.01)than those in the AS group. There were no statistical significant differences between the two groups in age,serum TG,TC,HDL-C,LDL-C and blood pressure,gender,cases with carotid artery plaque(all P>0.05). It was shown that there was no correlation between TXA2R gene polymorphism and AR. Conclusion The patients with smoking,high concentration of blood glucose have a higher incidence of AR,no correlation between TXA2R gene polymorphism and AR is found.
