β-FIBRINOGEN PROMOTER-455 G/A (HaeⅢ) POLYMORPHISM PREDICTION OF PLASMA FIBRINOGEN BUT NOT OF ISCHEMIC CEREBROVASCULAR DISEASE 总被引:1,自引:0,他引:1
Objective The-455 G/A (HaeⅢ) polymorphism of β-fibrinogen gene influences levels of plasma fibrinogen. We further investigated whether it influences the risk of isehemie cerebrovaseular disease. Methods We accumulated 134 acute isehemic eerebrovaseular disease (ICVD) eases and compared their -455 G/A status with a control group (n=166). The β-fibrinogen gene -455 G/A polymorphism was analyzed for all subjects by PCR-RFLP with the restrictive enzyme HaeⅢ. Results Plasma fibrinogen was higher in AA homozygous participants (341mg/dL) than in participants carrying the G allele: GA (290mg/dL), GG (298mg/dL) in the control group. Plasma fibrinogen was also higher in AA homozygous patients (353mg/dL) than in eases carrying the G allele: GA (287mg/dL), GG (302mg/dL) in the ICVD group. However, there was no significant association between β-fibrinogen gene -455 G/A polymorphism and ICVD group. Conclusions Although a small effect cannot be excluded, β-fibrinogen gene -455 G/A polymorphism is an independent predictor of plasma fibrinogen, but not of isehemie cerebrovaacular disease. 相似文献

A Meta-analysis of β-fibrinogen Gene-455G/A Polymorphism and Plasma Fibrinogen Level in Chinese Cerebral Infarction Patients 总被引:1,自引:0,他引:1
Objective To evaluate the correlation between the β-fibrinogen gene-455G/A polymorphism and cerebral infarction in Chinese population by means of meta-analysis. Methods Genetic association studies on evaluating the β-fibrinogen gene -455G/A polymorphism and cerebral infarction involving Chinese population published before December 2005 were collected from database of PubMed, EMBASE, and CNKI. All the data in literature were abstracted based on the defined selection criteria by two independent investigators. Publication bias was tested by funnel plot and the odd ratios of all studies were combined dependent on the result of heterogeneity test among the individual studies. The software Review Manager (Version 4.2) was used for meta-analysis. Results Eleven studies including 1405 patients and 1600 controls met the selection criteria. There was no publication bias in 11 reviewed studies. Heterogeneity test of reviewed studies showed statistically significant differences (χ2=24.58, P=0.006) among the ORs of individual studies. The combined OR of 11 studies of susceptibility to cerebral infarction in –455A allele carriers compared with the -455G/G wild homozygotes was 1.33 (95%CI 1.04-1.71, P=0.02). In the patients with cerebral infarction in 6 studies, the summarized average plasma fibrinogen level of allele A carrier was 0.29 g/L (95%CI 0.14-0.44, P=0.0002) higher than that of -455G/G homozygous ones. Conclusions β-fibrinogen gene -455G/A polymorphism might contribute to susceptibility of cerebral infarction in Chinese population; allele A increases the individual susceptibility to the disease. 相似文献

BACKGROUND: During the last 15 years, several risk markers for atherosclerosis, such as fibrinogen and D-dimer, have been identified. The role of elevated fibrinogen levels as an independent risk factor for coronary, cerebral, and peripheral vascular disease is well established on the basis of clinical and epidemiological studies. Increased D-dimer levels are associated with increased risk of future myocardial infarction, stroke, and peripheral vascular disease. The aim of this study was to evaluate the alterations in fibrinogen and D-dimer, which indicates overall thrombotic activity, in subjects with subclinical hyperthyroidism. MATERIAL/METHODS: Thirty-six subclinical hyperthyroidic subjects and 36 euthyroidic control subjects matched for age, gender, and body mass index were selected. The levels of plasma fibrinogen and D-dimer in all subjects were measured. RESULTS: The level of fibrinogen was significantly higher in the subclinical hyperthyroidic group than in the euthyroidic group (296.9+/-74.3 mg/dl vs. 255.0+/-41.7 mg/dl, p<0.001). The level of D-dimer was significantly higher in the subclinical hyperthyroidic group than in the euthyroidic group (261.9+/-47.8 mg/dl vs. 216.4+/-32.1 mg/dl, p<0.000). CONCLUSIONS: The results suggest that subjects with subclinical hyperthyroidism present a relatively hypercoagulable state. This state could contribute to increased thromboembolic risk in subclinical hyperthyroidism. 相似文献

A meta-analysis of relationship between β-fibrinogen gene -148C/T polymorphism and susceptibility to cerebral infarction in Han Chinese 总被引:5,自引:0,他引:5
Objective The results of studies on association between -148C/T polymorphism in promoter region of β-fibrinogen gene and susceptibility to cerebral infarction in Chinese population are controversial. In this study, we summarize the results of published works in this field by a meta-analysis. Data sources Genetic association studies evaluating the β-fibrinogen gene -148C/T polymorphisms and cerebral infarction involving Chinese population published before December 2005 were collected from PubMed, EMBASE and CNKI. Study selection Case control studies involving unrelated, Han subjects aged from 18 to 80 years, and the internationally recognized diagnostic standard of cerebral infarction and genotype frequencies in control group consistent with Hardy-Weinberg equilibrium were used. Publication bias was tested by funnel plot and the odds ratios of all studies were combined dependent on the result of heterogeneity test among the individual studies. The software Review Manager (Version 4.2) was used for meta-analysis. Results Eleven studies including 1223 patients and 1433 controls met the selection criteria. There was no heterogeneity among the odds ratios (ORs) of individual studies (χ(2)=17.82, P=0.06). The combined OR of susceptibility to cerebral infarction in -148T allele carriers compared to the wild homozygote was 1.32 (95%CI 1.12 to 1.55, P=0.0008). In the patients with cerebral infarction, the average plasma fibrinogen level of allele T carrier was 0.42 g/L (95%CI 0.29 to 0.54, P<0.001), higher than that of -148C/C homozygous ones. Conclusions β-fibrinogen gene -148C/T polymorphism might contribute to susceptibility to cerebral infarction in Han Chinese. To reach a definitive conclusion, further gene to gene and gene to environment interactions studies on β-fibrinogen polymorphisms and cerebral infarction with large sample size are required. 相似文献

CONTEXT: Elevated high-density lipoprotein cholesterol (HDL-C) levels have been shown to be protective against cardiovascular disease. However, the association of specific lipoprotein classes and ischemic stroke has not been well defined, particularly in higher-risk minority populations. OBJECTIVE: To evaluate the association between HDL-C and ischemic stroke in an elderly, racially or ethnically diverse population. DESIGN: Population-based, incident case-control study conducted July 1993 through June 1997. SETTING: A multiethnic community in northern Manhattan, New York, NY. PARTICIPANTS: Cases (n = 539) of first ischemic stroke (67% aged >/=65 years; 55% women; 53% Hispanic, 28% black, and 19% white) were enrolled and matched by age, sex, and race or ethnicity to stroke-free community residents (controls; n = 905). MAIN OUTCOME MEASURE: Independent association of fasting HDL-C levels, determined at enrollment, with ischemic stroke, including atherosclerotic and nonatherosclerotic ischemic stroke subtypes. RESULTS: After risk factor adjustment, a protective effect was observed for HDL-C levels of at least 35 mg/dL (0.91 mmol/L) (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.39-0.72). A dose-response relationship was observed (OR, 0.65; 95% CI, 0.47-0.90 and OR, 0.31; 95% CI, 0.21-0.46) for HDL-C levels of 35 to 49 mg/dL (0.91-1.28 mmol/L) and at least 50 mg/dL (1.29 mmol/L), respectively. The protective effect of a higher HDL-C level was significant among participants aged 75 years or older (OR, 0.51; 95% CI, 0.27-0.94), was more potent for the atherosclerotic stroke subtype (OR, 0.20; 95% CI, 0.08-0.50), and was present in all 3 racial or ethnic groups studied. CONCLUSIONS: Increased HDL-C levels are associated with reduced risk of ischemic stroke in the elderly and among different racial or ethnic groups. These data add to the evidence relating lipids to stroke and support HDL-C as an important modifiable stroke risk factor. 相似文献

A total of 110 elderly people with hyperlipidemia were randomly assigned to one of two groups. The experimental group consumed an ordinary diet plus foods containing refined Konjac meal, and the control group consumed only the ordinary diet. The experiment was carried out for 45 days. The results indicate that for the experimental group blood levels of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) were significantly lowered (P less than 0.01) at the end of the trial, whereas high-density lipoprotein cholesterol (HDL-C) and apoprotein (AI) levels were significantly elevated (P less than 0.01). In contrast, for the control group, the changes in the above parameters were insignificant. The differences in TC, TG, LDL-C, and HDL-C levels between the two groups were statistically significant. The effects of refined Konjac meal on lipid levels in the blood were somewhat different between patients with hyperlipidemia and subjects with risk critical values only. For the former, TG and TC were decreased by 83.8 +/- 133.5 mg/dl, and 42.4 +/- 23.4 mg/dl, respectively; but for the latter, they are decreased only by -1.1 +/- 23.1 mg/dl and 8.3 +/- 18.2 mg/dl, respectively; the difference mentioned above is statistically significant (P less than 0.01). 相似文献
