ABSTRACT

Objectives:To observe the clinical and coronary artery computed tomography(CT) characteristics of patients with ankylosing spondylitis. Methods:Data from 33 consecutive patients with ankylosing spondylitis admitted due to chest discomfort in Fuwai Hospital from January 2014 to June 2017 were analyzed, 33 age and sex matched patients with no ankylosing spondylitis were selected as the control group. Coronary artery CT features was compared between the two groups. Results:Incidence of hypertension, smoking, diabetes and hyperlipidemia, BMI values were similar between the two groups. Blood lipid level (high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride and, total cholesterol), creatinine and uric acid values were also similar between the two groups. Erythrocyte sedimentation rate (ESR) ([14.15±12.81]m/s vs [7.79±6.26]m/s, P=0.013) and high C-reactive protein (hs-CRP) ([6.88±5.65]ng/L vs [3.16±3.13]ng/L, P=0.002) values were significantly higher in ankylosing spondylitis group than in the control group. Percent of coronary artery stenosis (>50%) was significantly higher in ankylosing spondylitis group than in the control group (23[69.7%] vs 14[42.4%], P=0.026). Coronary artery calcification was significantly higher in ankylosing spondylitis group than in the control group (22 [66.7%] vs 9[27.3%], P=0.001). Conclusions:Degree of coronary artery stenosis and calcification as well as inflammatory index (ESR and hs-CRP) are significantly higher in ankylosing spondylitis patients compared to control patients.

ABSTRACT

Objective To investigate the effects of the polymorphisms in the promoter of ATP binding cassette transporter (ABCG1) on the transcription activity,and the relationship of the polymorphisms with the susceptibility to coronary artery disease (CAD).Methods A case-control study was conducted,217 CADpatients and 142 controls were enrolled in this study.Thesingle nucleotide polymorphisms (SNPs) in the promoter of ABCG1 were identified by sequencing.The promoter haplotypes of ABCG1 were determined with allele specific primer sequencing or Gene cloning sequencing.The transcription activity of the promoter haplotypes were evaluated with dual luciferase reporter system.The frequency of SNPs and haplotypes were analyzed between CAD group and the control group,premature CAD and non-premature CAD group,as well as multivessel lesion and single vessel lesion group.The frequency distribution was compared between two groups with x2 test or Fisher exact test.The difference of the luciferase activity was compared between groups by t-test or one-way analysis of variance.Results Only 3 SNPs were found in ABCG1 promoter sequence of about 1 000 bp upstream of the transcription start site,which are-384 (A/G),-204 (A/C) and-134 (T/G),respectively.The 3 SNPs are in strong linkage disequilibrium,Tajima's D =2.655 (P < 0.01),which constituted 3 haplotypes.There was no significant difference in SNPs and haplotype frequency between the CAD group and the normal control group,and the severity of vascular disease and the early onset of coronary heart disease were not associated with the polymorphisms in ABCG1 promoter.There was no significant difference in the transcriptional activity of the three constitutive promoter haplotypes,but the transcriptional activity was notably elevated as the GAT haplotype was mutated into GAG (P < 0.05).Conclusions The 3 SNPs identified in ABCG1 promoter region A did not alter the promoter activity.There was no significant correlation between the frequency distribution of SNPs and promoter haplotypes and the susceptibility to CAD.

ABSTRACT

Objective To investigate correlational study on the levels of homocysteinin with the severity of coronary artery in patients with coronary atherosclerotic disease.Methods 60 patients with coronary atherosclerotic disease were enrolled in from Janu-ary 2013 to December 2014 in Beijiao hospital affiliated Southern medical university .All patients received coronary artery angiograph and the levels of circulating homocysteinin were determined.According to the levels of circulating homocysteinin, 60 patients were de-vided into coronary atherosclerotic disease group and coronary atherosclerotic disease group with hyperhomocysteinemia ( HHcy) .The levels of homocysteinin and the severity of coronary artery in patients with coronary atherosclerotic disease and correlation between the two group were analyzed.Results Compared with coronary atherosclerotic disease patients,the levels of homocysteinemia and Genisi score were increased in patients with coronary atherosclerotic disease with HHcy (p<0.05).Correlation analysis showed that the lev-els of homocystein is positively correlated with Genisi score (p<0.05).Conclusion HHcy is a important risk for coronary athero-sclerotic disease and positively related with the severity of coronary artery in patients with coronary atherosclerotic disease .
