ABSTRACT
Objective To observe the relationship between CYP2C19 gene polymorphisms and major adverse cardiovascular events in the patients of acute coronary syndrome (ACS) who accepted percutaneous coronary intervention (PCI) in Han population from Dalian. Methods A total 809 cases with ACS who had undergone PCI in the cardiology department of Dalian Municipal Central Hospital from Janurary 2012 to Janurary 2014 were selected,Among 809 cases of ACS,there were 178 cases of acute ST segment elevation myocardial infarction (STEMI),105 cases of acute non ST segment elevation myocardial infarction (NSTEMI) and 526 cases of unstable angina. The patients were divided into three groups according to their CYP2C19 genotype.CYP2C19 genotype (*1/*1) were classified as extensive metabolizers (EM group), CYP2C19 genotype (*1/*2、*1/*3) were classified as intermediate metabolizers (IM group) and CYP2C19 genotype (*2/*2、*3/*3、*2/*3) were classified as poor metabolizers (PM group). The occurrence of major adverse cardiovascular events at least 24 months was observed. Results Seven hundred and ninety patients finished the follow-up at least 24 months, 19 patients lost in follow-up, 350 cases (43.2%) were CYP2C19 (*1/*1),318 cases (39.3%) were CYP2C19(*1/*2), 42 cases(5.2%) were CYP2C19 (*1/*3),77 cases (9.5%) were CYP2C19 (*2/*2), 21 case(2.2%)were CYP2C19 (*2/*3), and 1 case (0.1%) was CYP2C19(*3/*3), 350 cases (43.2%) were classified as EM group, 360 cases (44.5%) were classified as IM group, and 99 cases(12.2%)were classified as PM group. No significant difference in age, gender, hypertention, diabetes mellitus, smoking was shown among three groups (P > 0.05). The rate of MACE were 3.3% , 8 cases had target lesion revascularization(EM group 3 cases, IM group 3 cases, PM group 2 cases), 2 cases had non-fatal myocardial infarction (IM group 1 case, PM group 1 case), 15 cases were died(EM group 6 cases, IM group 7 cases, PM group 2 cases), 1 case had subacute stent thrombosis in IM group. The rates of MACE were higher in PM group (5.1%) than those in EM group(2.65%) and IM group (3.41%) , but there was no significant difference in three groups (P>0.05). There was no significant difference in the rate of target lesion revascularization , thrombus in stent, non- fatal myocardial infarction and death among three groups(P > 0.05). Conclusions There is no significant correlation between CYP2C19 gene polymorphism and long-term prognosis in patients with ACS who accepte PCI treatment in Han population from Dalian.
ABSTRACT
Objective To investigate the role of macrophage migration inhibitory factor (MIF) gene polymorphisms in adult onset Still's disease(AOSD).Methods Plasma MIF levels were measured by enzymelinked immunosorbent assay (ELISA).Genomic DNAs were collected from patients and controls.The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay and short tandem repeat genotyping were used to detect the polymorphisms of MIF gene promoter.The -173 G/C SNP and -794 CATT repeat genotype and allele frequencies between patients and controls were capared using pearson's Chi-square test.The non-parmetric Mann-Whithey U test was conducted to compare MIF expressin between cases and controls.Results Plasma MIF levels were significantly higher in AOSD (119±113) ng/ml than those in controls (55±29) ng/ml (P＜0.01).Individuals with -173 * C allele (OR=1.776; 95％CI 1.101-2.864; P=0.017) or -794 *5-CATT allele (OR=1.81;95％CI 1.27-2.58; P=0.001) were at increased risk for AOSD.Conclusion The MIF gene polymorphisms are associated with AOSD.
ABSTRACT
0.05).Conclusion There is susceptibility correlation between the UC patients of north Chinese and the rising of C/T gene polymorphisms and T allele gene frequency in IL-1B +3962 site,but there isn't correlation between the gene polymorphisms in IL-1B +3962 site and different invasion location of UC of north Chinese.IFN-?+874 hasn't correlation with UC of north Chinese.
