Association of vascular endothelial growth factor 936C/T polymorphism and the susceptibility to colorectal adenoma / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To examine the association between polymorphism of vascular endothelial growth factor(VEGF)1498 C/T,936 C/T and colorectal adenoma genetic susceptibility.</p><p><b>METHODS</b>A case-control study of 224 colorectal adenomas and 200 controls was conducted and VEGF genotypes were determined based on TaqMan-probe assay. The epidemiological factors were collected through questionnaire. Accordingly, the clinicopathological data of each sample were also investigated.</p><p><b>RESULTS</b>The carriage of 936 CT and CT+TT genotypes had significantly higher risk of colorectal adenoma (CT vs. CC, OR=2.00, 95% CI: 1.23-3.25, P=0.006; CT+TT vs. CC, OR=2.04, 95% CI:1.28-3.26, P=0.003). 936-T allele carriage had increased risk of colorectal adenoma (OR=1.91, 95% CI:1.25-2.91, P=0.003). The genotypes of 1498 C/T and the frequency of C/T allele showed no differences between healthy persons and patients (P>0.05). In patients with 936 CT+TT and 936-T allele implied a tendency of villous adenoma category (CT+TT vs. CC, OR=2.54, 95% CI:1.12-5.75, P=0.040; T allele vs. C allele, OR=3.08, 95% CI, 1.64-5.80, P=0.001).</p><p><b>CONCLUSION</b>VEGF 936 C/T polymorphism can influence susceptibility to colorectal adenoma.</p>

Perpetual impact of pregnancy-induced hypertension on blood pressure / 中华心血管病杂志

<p><b>OBJECTIVE</b>To explore the perpetual impact of pregnancy-induced hypertension on blood pressure.</p><p><b>METHODS</b>This retrospective cohort study included 782 cases of pregnant women who hospitalized at Kailuan Linxi hospital between October 1976 and August 2001. Patients were divided to with pregnancy induced hypertension (PIH, n = 77) group and non pregnancy induced hypertension (NPIH, n = 705) group. Patients were followed for 5 to 34 years (mean 18.8 +/- 5.3 years), the incidence of essential hypertension was obtained in July 2006-September 2007.</p><p><b>RESULTS</b>(1) The cumulative incidence of essential hypertension during follow up was significantly high in PIH group (29.87%) than that in NPIH group 18.87% (P = 0.022). (2) At the final follow up, waist circumference; [(86.06 +/- 10.15) cm vs. (83.07 +/- 8.19) cm, P = 0.015], BMI [(24.83 +/- 4.01) kg/m(2) vs. (23.50 +/- 3.39) kg/m(2), P = 0.006], TC [(5.11 +/- 0.88) mmol/L vs. (4.89 +/- 0.94) mmol/L, P = 0.045] and GLU [(5.57 +/- 1.78) mmol/L vs. (5.20 +/- 1.38) mmol/L, P = 0.010] were all significantly higher in PIH group than those in NPIH group. (3) After adjustment of age and BMI, PIH was still significantly correlated with long-term systolic blood pressure levels (P = 0.048), fasting glucose level was also significantly associated with long-term systolic blood pressure. Age, BMI, white blood cell count and uric acid were also predictors for perpetual systolic and diastolic blood pressure levels.</p><p><b>CONCLUSIONS</b>Incidence of essential hypertension in women with PIH was higher than that in women without PIH. After adjustment of covariates including age, BMI, and glucose, PIH was significantly associated with the level of systolic blood pressure. BMI, fasting glucose and cholesterol levels might contribute to the increase of systolic blood pressure in patients with PIH.</p>

Effects of Long-term Treatment with Hydrochlorothiazide Combined Spironolactone or Captopril on Left Ventricular Hypertrophy in Hypertensive Patients / 中华高血压杂志

0.05);2)After 12,24,36 months' treatment,BP was decreased significantly in each group (P0.05).Conclusion Both combined spirono- lactone/HCTZ and captopril/HCTZ significantly reduced BP and LVMI or LVMI and the maguitude of reduction was further enhanced after prolonged treatment.

Association of polymorphism in alpha-adducin gene with antihypertensive effect of Hydrochlorothiazide / 中华心血管病杂志

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
