RESUMO
Objective To investigate the possible association between the thrombospandin-1(TSP-1) gene GI678A (Ala523Thr)polymorphism and acute coronary syndrome (ACS) in a Chinese Han population.Method he ease cohort studied was compsed of 412 hospitalized patients with ACS recruited from four participating hospitals between November 2003 and May 2006.The diagnosis of ACS was based on the criteria of AHA/ACC set in 2002.The eontrul group was consisted of 319 age- and sex-matched subjects from partiei pating hospitals,and they were free from coronary artery disease judged by history,clinical examination,electrocardiography,exercise test and angiography.The TSP-1 GI678A polymorphism was determined by polymerase ehain reaction and restriction fragment length polymurphism analysis(PCR-RFLP).Results The prevalence OfAA genotype of the G1678A polymorphismin patients with ACS was significantly higher than that in the control subjects (49.5%% vs.40.4%,P=0.015).The frequencies of GA and GG genotypes were not significantly different between patients with ACS and controls (CA:39.3% vs.46.1%,P=0.070;CA;11.2% vs.13.5%,P=0.340).The frequencies of A allele in the ACS group and control group were 69.2% and 63.5%,respectively (P=0.022).Furthermore,multiple logistic regression analysis showed that the AA genotype was a significant risk factor for ACS (OR=1.52;95% CI:1.11～2.08;P=0.010).Conclusions The present findings suggest that the AA genotype in TSP-1 gene GI678A polymorphism may be associated with a risk factor for ACS in the Hart nationality of China.The AA genotype may be a genetic marker of the liability to the inheritance of AC,S.
RESUMO
Thirty seven patients with congestive heart failure (CHF) were divided into cilazapril group (n=19) and general treatment group (n=18). Serum levels of interleukin-6 (IL-6) ,interleukin-8 (IL-8) , interleukin-10(IL-10) and tumor necrosis factor-α(TNF-α) , left ventricular ejection fraction (LVEF) ,left ventricular end-diastolic diameter (LVEDD), cardiac output (CO) and fractional shortening (FS) were measured before and after treatment. Serum levels of cytokines were also measured in 40 healthy individuals (control group). Results: The serum levels of IL-6, IL-8, IL-10 and TNF-α in CHF patients were significantly higher than those in the control group ( all P<0.01 ) ; After treatment, the serum IL-6, IL-8 and TNF-α were significantly decreased (P<0.01 ,P<0.05 ) in the cilazapril group. The LVEF, FS, CO were significantly increased in the Cilazapril group ( P<0.01 ) ; And the serum levels of IL-6 were significantly decreased in the cilazapril group as compared with the general treatment group ( P<0.05 ), however, after treatment, the EF, LVEF, FS and CO had no statistical differences in the cilazapril group as compared with the general treatment group. In the control group only LVEF and FS improved(P<0.01) ; Cytokine levels showed no changes. It suggests that cilazapril can reduce the serum levels of pro-inflammatory cytokines, increased the serum levels of anti-inflammatory cytokine, protect and improved cardiac function in the patients with congestive heart failure.
