RESUMO
Objective:To investigate the correlation between interleukin-27(IL-27)polymorphisms and coronary heart disease(CHD)in the Guangxi Zhuang population.Methods:A total of 1 218 subjects were enrolled in this case-control study, and 571 cases were in the CHD group and 647 were in the control group.The Sequenom MassArray system was used to genotype IL-27 single nucleotide polymorphisms(SNPs), and other biochemical parameters were tested by using the standard protocol in the laboratory of our hospital.The correlation between IL-27 SNPs and CHD was evaluated by Logistic regression analysis, and risk factors including age, smoking, drinking, history of hypertension, history of diabetes mellitus and family history of CHD were adjusted in this model.Methods:Logistic regression analysis results indicated that the risk of CHD was elevated in subjects with the CC genotype of IL-27 rs428253, compared with those with the GG genotype( OR=2.18, 95% CI: 1.09-4.37, P<0.05). After adjustment for the related risk factors, the risk of CHD also increased in subjects with the CC genotype of IL-27 rs428253, compared with those with the GG genotype( R=2.82, 95% CI: 1.31-6.07, P<0.05). IL-27 rs4740, rs17855750, rs181206 and rs40837(all P>0.05)polymorphisms had no correlation with CHD in the Zhuang population, and there were no significant differences in C-reactive protein, total cholesterol, triglyceride or low-density lipoprotein cholesterol levels between CHD patients and controls with different genotypes of IL-27 rs428253(all P>0.05). Conclusions:IL-27 rs428253 polymorphism is correlated with the risk of CHD in the Guangxi Zhuang population.
RESUMO
Objective To investigate the correlation between plasma homocysteine(Hcy) and long term occurrence of main adverse cardiac events(MACE) in the patients with acute myocardial infarction(AMI).Methods A total of 326 inpatients with AMI in the cardiology department of this hospital from Mar.2012 to Dec.2014 were continuously included.The related laboratory biochemical indicators such as Hcy were detected according to the standard flow process by the hospital clinical laboratory department.The Hcy level and MACE occurrence rate were performed the receiver operating characteristic(ROC) curve analysis.The research subjects were divided into the Hcy(L) group and Hcy(H) group according to the cut-off value 11.69μmol/L.The base line data of all subjects were collected and the follow up was conducted for recording MACE.Results The plasma N-terminal pro-brain natriuretic peptide (NT-ProBNP) level in the Hcy(L) group was significantly lower than that in the Hcy(H) group[-(501.46-±-118.35)pg/mL vs.(1 324.11 ± 523.13) pg/mL,P =0.02],while the left ventricular ejection fraction(LVEF) was significantly higher than that in the Hcy(H) group[(55.23 ± 9.48) ％ vs.(50.79 ± 10.68) ％,P =0.03].After 1-year follow up,LVEF in the Hcy(H) group was significantly decreased compared with the base line [(45.32±10.18)％ vs.(50.79±10.68)％,P＜0.05],moreover the MACE occurrence risk in the Hcy(H) group was significantly higher than that in the Hcy(L) group,the difference after correcting the related confounding factors had statistical significance (P=0.048),but LVEF and minor axis shortening rate of left ventricle(FS) in the Hcy(L) group had no obvious difference compared with the base line data[(54.43 ± 10.68)％ vs.(55.23± 9.48) ％,(28.56±6.21) ％ vs.(29.22±5.30) ％,P＞0.05].Conclusion The risk of long term MACE occurrence in the patients with AMI complicating plasma high Hcy level is obviously increased compared with that in the patients with plasma low Hcy level and the prognosis is poor,prompting that plasma high Hcy level is one of possible independent predicting factors for poor prognosis in the patients with AML But its action mechanism and whether the Hcy interventional therapy improving prognosis of AMI patients still need to further study.
RESUMO
Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.
