Correlation between PPARγ C161T polymorphisms and atherothrombotic infarction in a Chinese Han population / 国际脑血管病杂志

ABSTRACT

Objective To investigate the relationship between the C161T polymorphisms in peroxisome proliferators-activated receptor γ (PPARγ) gene and atherothrombotic infarction (ATI) in a Chinese Han population.Methods The patients with atherothrombotic infarction and controls,who without histories of stroke,transient ischemic attack and myocardial infarction were enrolled.Genotypes of the PPARγ C161T polymorphisms were determined using the polymerase chain reaction-restriction fragment length polymorphism.The frequencies of genotype and allele in patients with ATI and controls were compared.Results A total of 112 ATI patients and 112 controls were enrolled.There were no significant differences in the age (67.9± 11.73 years vs.66.5 ± 10.35 years; t =0.386,P =0.701) and the proportion of male (61.61％ vs.58.04％ ;x2 =0.297,P =0.586) in the ATI group and the control group.The proportions of hypertension (59.82％ vs.44.62％ ;x2 =5.171,P =0.023),type 2 diabetes mellitus (26.79％ vs.9.82％;x2 =10.778,P =0.001) in the ATI group were significantly higher than those in the control group.Body mass index (25.13±1.86 kg/m2 vs.24.11 ± 1.81 kg/m2; t =3.543,P=0.001),systolic pressure (158.84 ± 20.15 mm Hg vs.135.82 ± 19.58 mm Hg; t =7.350,P =0.000),diastolic pressure (76.90 ± 13.64 mm Hg vs.68.90 ± 8.52 mm Hg; t =4.374,P =0.000) and the level of fasting blood glucose (6.523 ± 2.831 mmol/L vs.5.706 ± 2.177 mmol/L; t =2.026,P =0.044) in the ATI group were significantly higher than those in the control group.The genotype frequencies of CC,CT and TT in the ATI group were 77.7％,17.0％ and 5.4％,respectively,and in the control group were 69.6％,22.3％ and 8.0％,respectively.There were no significant difference between the two groups (x2 =1.909,P =0.385).The allele frequencies of C and T in the ATI group were 86.2％ and 13.8％,respectively,and in the control group were 80.8％ and 19.2％,respectively.There were no significant difference between the two groups (x2 =2.331,P =0.127).Conclusions PPARγ C161T polymorphisms may be not associated with the onset of ATI in a Chinese Han population.
