RESUMEN
Objective To investigate the association between the phosphodiesterase 4D(PDE4D) gene rs153031 polymorphism and the susceptibility of unstable angina pectoris(UAP) in Chinese Han population of Changwu region .Methods The PDE4D gene rs153031 polymorphism was genotyped by Taqman probe in 172 UAP patients(UAP group) ,as well as in gender-and-age-matched 220 subjects without coronary heart disease(CHD)(control group) .Results In this crowd ,there was PDE4D gene rs153031 poly-morphism in patients with UAP and in subjects without CHD .Compared with control group ,frequencies of GG ,GA ,AA genotypes and G allele of rs153031 in UAP group showed no statistical differences (P> 0 .05) .Conclusion In Chinese Han population of Changwu region ,PDE4D gene rs153031 polymorphism shows no association with the susceptibility of UAP .
RESUMEN
Objective To investigate the relationship between serum C-reactive protein(CRP) level ,CRP gene C+1444T poly-morphism and the risk with Acute myocardial infarction (AMI) in Chinese Han population in Sunan region .Methods The CRP gene C+1444T polymorphism was genotyped by Polymerase reaction restriction-fragment length polymorphism (PCR-RFLP) and the serum CRP level was measured by enzyme linked immunosorbent assay (ELISA) between 227 patients with AMI(AMI group) and 161 control subjects .Results No differences were found in genotype distribution between AMI group and controls (CC 82 .38% ,CT 17 .62% ,TT 0% vs 86 .96% ,13 .04% ,0% )(P>0 .05) .The serum CRP level in AMI group was significantly higher than controls(P< 0 .01) .There was no differences in the serum level between any genotypes of the CRP gene C + 1444T (P<0 .05) .Conclusion The CRP gene C+1444T polymorphism is not associate with increased risk of AMI ,and it have no effect with the serum level in Chinese Han population in Sunan region .
