    ABSTRACT: To study the association of fibrinogen(Fg) B beta -854G/A, -455G/A, -249C/T, -148C/T, 448G/A and Bcl-1G/A gene polymorphisms with factors affecting obesity, and the fibrinogen function such as plasma fibrinogen concentration and molecular reactivity. One thousand and three hundred ninety-one subjects from Kailuan corporation were enrolled by medical examination and questionnaire survey, and were divided into normal weight, overweight and obese groups based on body mass index (BMI). Blood biochemistry, fibrinogen concentration, fibrin monomer polymerized velocity (FMPV), and FMPV/A(max) were measured. The gene polymorphisms of the six loci were detected by polymerase chain reaction-restriction fragment length polymorphism. The frequencies of Bcl-1A and its mutated genotype in the overweight group were significantly higher than that in the normal weight group (P< 0.01). In all the three groups, Fg concentration, FMPV, FMPV/A(max) in individuals with B beta -854 mutated genotype were significantly higher than those with wild type genotype (P< 0.01), and in the overweight group, FMPV/A(max) in those with B beta -455 mutated genotype, FMPV in those with B beta -249 mutated genotype, were higher than those with wild type genotype (P< 0.05). Individuals with Bcl-1A and its mutated genotype are susceptible to overweight. The B beta -455 and -249 mutated genotypes are accumulative genes for overweight by regulating the Fg function.

    ABSTRACT: To study the distribution characteristics of Beta-fibrinogen (Fg)B gene-854G/A, -455G/A, -249C/T, -148C/T, 448G/A and Bcl-1 G/A polymorphism in North China Han population, and the influence on plasma Fg concentration and molecular reactivity. Further more, to explore the role of Fg gene polymorphisms combining with multi-physiological and environmental factors in the development of cerebral infarction. Cluster sampling, health examination and questionnaires surveys of 1652 subjects from Tangshan Kailuan Group Corporation were conducted. Blood biochemistry, Fg concentration, fibrin monomer polymerized velocity (FMPV), absorbance maximum (Amax) and FMPV/Amax were measured. The six polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism. In the population, the proportion of the FgB beta-249 T variation allele was 65.49%, while the proportion of the rest loci was predominantly wild type. The significant differences in Fg concentration and FMPV/Amax were found in -854 genotype groups. The Fg concentration in -854GA group was higher than those in GG and AA group. Only the distribution frequencies of FgB beta Bcl-1 A variation allele, GA and AA genotype in the cerebral infarction group were higher than those in non-infarction group, and the prevalence of cerebral infarction in AA genotype group was higher than other groups (the probability value of above-mentioned results were all P<0.01). FgB beta Bcl-1A allele and variation genotype were susceptible to cerebral infarction. FgB beta-455GA/448G linkage genotype may contribute to the increased plasma Fg concentration. FgB beta-854 was one of the main controlling gene loci for plasma Fg concentration and molecular reactivity.

    ABSTRACT: Since males are at higher risk of cardiovascular diseases than females, the aim of the study was to examine whether there is an association between BP and a polymorphic Hind III biallelic marker in nonrecombining region of Y chromosome in essential hypertension in Tangshan district in China. In the study, 225 patients with essential hypertension and 187 healthy people were enrolled into this study as control group. DNA was extracted from white blood cell. Segments of polymorphic Hind III restriction site of the Y chromosome were amplified from DNA by polymerase chain reaction (PCR). PCR products were restricted with 10 U of Hind III for a night at 37 degrees C. The digested products were subjected to electrophoresis in 3% agarose gels, and stained with ethidium bromide. We amplified 178 controls (95.2%) and 216 essential hypertensive patients (96.0%) successfully. Hind III(-) genotype was found in 45.8% of the men in essential hypertension and in 32.0% of the men in the controlled group. The Hind III(-) genotype was significantly higher than that in the controls (chi2 = 7.782, P = 0.007). However, the Hind III(+) genotype was lower in SBP (133.16 mm Hg +/- 21.60 mm Hg vs. 143.58 mm Hg +/- 24.16 mm Hg, P < 0.001), DBP (82.82 mm Hg +/- 11.72 mm Hg vs. 86.82 mm Hg +/- 12.65 mm Hg, P = 0.001), pulse pressure (50.34 mm Hg +/- 14.31 mm Hg vs. 56.76 mm Hg +/- 14.20 mm Hg, P < 0.001) and mean arterial pressure (99.59 mm Hg +/- 14.19 mm Hg vs. 105.74 mm Hg +/- 15.31 mm Hg, P < 0.001) than the Hind III(-) genotype. Polymorphic Hind III restriction site of the Y chromosome seemed to be associated with essential hypertension in Tangshan district in China.

    ABSTRACT: To study the association of beta-fibrinogen(Fg) gene -148 C/T and 448 G/A polymorphisms, plasma Fg concentration, molecular reactivity and the type of cerebral infarction. Gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The plasma Fg concentration and the molecular reactivity were also determined. The Fg concentration in MCI patients with T -148 allele was higher than that in PCI patients and controls. The MCI patients with A448 allele had higher Fg concentration, FMPV and FMPV/Amax when compared with controls, and had higher FMPV/Amax when compared with PCI patients. FgB beta -148 and 448 mutational genotypes have impact on Fg concentrationì and therefore increase the risk of MCI.

    ABSTRACT: To explore the association between G614T single nuclear polymorphism (SNP) of the alpha-adducin gene and the antihypertensive effect of hydrochlorothiazide (HCTZ) in essential hypertensive (EH) patients. Eight hundred twenty nine EH patients were given 12.5 mg HCTZ/d for six weeks. Alpha-adducin gene G614T SNP in the tenth exon was determined by PCR-RFLP in 754 patients with complete records. All the patients were grouped according to TT, GT and GG genotypes. After 6 weeks of HCTZ treatment, the decreases in DBP and MAP of patients carrying 614T allele of alpha-adducin were significantly greater than that of those carrying GG homozygotes (P < 0.05). The decreases in SBP and MAP were significantly greater in patients with the TT genotype as compared with GT or GG genotype (P < 0.05). The effective rate of BP fall by HCTZ was higher in patients with TT genotype than those with GT or GG genotype (P < 0.05). Multivariate stepwise regression analysis showed that the TT genotype and the baseline SBP were the two major predictors affecting the decrease in SBP. The present study suggests that the alpha-adducin G614T polymorphism is associated with the antihypertensive effect of HCTZ, which is more effective in patients with TT genotype.

    ABSTRACT: To explore the relation of angiotensin-converting enzyme (ACE) gene polymorphism, angiotensin II type I receptor (ATIR) gene polymorphism and other factors on cerebral infarction. One thousand three hundred fifty-one subjects from Tangshan coalmine were enrolled with study method of cluster sampling. Face to face interviews were conducted to fill in questionnaires by trained interviewers. ACE gene, ATIR gene and inflammation factors including tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), IL-8, IL-10, C reactive protein (CRP), fibrinogen (Fg), fibrin monome polymerized velocity (FMPV), absorbance maximum (A(max)), FMPV/A(max), were measured. No different prevalence rates of ACE genotype were found on cerebral infarction. The distributions of AA genotype of ATIR gene in the cerebral infarction was higher than that of the controls. The prevalence of AA genotype was higher than other groups, but the prevalence of combined genotype did not show much difference. Under the existence of factors that related to cerebral infarction, AA genotype frequencies were higher than those of non-smoking and with hypertension. IL-6, ATIR gene polymorphism, sex, FMPV/A(max) were strongly related to cerebral infarction. The level of IL-6 was higher than the normal ones. The prevalence of cerebral infarction obviously increased in the hypertensive groups having AA genotype of ATIR gene. In the cerebral infarction groups, the level of IL-6 was higher than that in the normal population, indicating that these can be resulted from local inflammation and immunity reactivity. Environmental and genetic factors in the pathogenesis of cerebral infarction might have coordinating functions.

    ABSTRACT: To observe the distribution character of angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in Chinese population and its relationship with essential hypertension. Polymerase chain reaction (PCR) technique was used to detect the angiotensin converting enzyme gene I/D polymorphism in 2966 subjects of Kailuan Coal Mine, and further restriction analysis was performed. The frequencies of ACE II, ID, DD genotypes in total study population were 41.5%, 38.4%, 20.1%, respectively. The DD genotypes in hypertensive group and that in control group were 18.9% and 21.0%, respectively. There was no significant difference between hypertensive group and control group (P>0.05). The same result was seen after stratification by age and gender in each group, respectively(P>0.05). The DD genotype and D allele showed a tendency to decrease with the increase of age (P<0.001). The above results suggested that essential hypertension was not associated with ACE I/D polymorphism. The distributions of ACE genotype and allele varied with age, and the subjects with the character of DD genotype were at higher risk of early death.
