Background Familial hyperaldosteronism type Ⅱ(FH-Ⅱ) is characterized by autosomal dominant inheritance and hyperaldosteronism.Linkage analysis demonstrated chromosome 7q22 most likely harbor the genetic defect.Objective To identify the disease locus in a Chinese pedigree with FH-Ⅱ using genetic linkage analysis.Methods Haplotypes of the FH-Ⅱ pedigree were analyzed using four microsatellite markers(D7S531,D7S2521,D7S511,D7S481) at 7p22 to determine the critical region,and multipoint logarithm of odds(LOD) scores were calculated to assess linkage with FH-Ⅱ.Results Several members(affected members) in the family had hypertension,hypokalemia,hyperaldosteronism,low renin activity.Hypertension and hypokalemia was improved by spironolactone test.Dexamethasone suppression test was performed but without clinical or hyperaldosteronism improvement in three affected members,confirmed FH-Ⅱ family pedigree.The same haplotypes D7S531(ac,n=24)-D7S2521(ac,n=11)-D7S511(ca,n=21)-D7S481(ac,n=16) were shared by all known affected members and one suspicious member,but also by one unaffected member of the family,making it unlikely that this region contains the causative gene mutation.In this FH-Ⅱ family,the LOD scores of the four markers were

Background Hypertension and dyslipidemia are the 2 important risk factors of cardiovascular affecting the prognosis of cardiovascular disease. However paucity data of characteristics of lipid metabolism and prognosis of cardiovascular diseases in high-risk groups with hypertension are available. Objective To analyze the lipid metabolism level and the relevant risk factors of inpatients with essential hypertension (EH) from 2000 to 2007. Methods Retrospective study was performed based on the clinical characteristic and the relationship between different kinds of hyperlipidemia and target organ damages in inpatient with EH. Results For the level of triglyceride (TG) and the prevalence of hypertriglyceridemia,males(n=3056) were significantly higher than females(n=1932)(P

Chinese Journal of Hypertension 2007;0(02):-
Background Atrial fibrillation (AF) is one of the most prevalent arrthythmias. Hypertension independently accounts for more AF cases than any other risk factors. Therefore,prevention of risk factors in patients with essential hypertensives(EH) is important for early prevention and diagnosis of AF. However,only a few data are available regarding left ventricle remodeling in essential hypertensive patients with atrial fibrillation(EH+AF). Objective To study the characteristics of left heart remodeling and function and its clinical significance in EH+AF,and predict some risk factors of AF. Methods All 561 patients were recruited which included EH+AF(n=224),EH alone(n=171),AF alone(n=166) with normal subjects as control(n=157). Interventricula septal thickness at end-diastole(IVSTd),posterior left ventricular wall thickness at end-diastole(LVPWTd),left ventricular end-diastolic dimension(LVEDD),left ventricular end-systolic dimension(LVESD),left atrial dimension (LAD),left ventricular ejection fraction stroke volume(LVEF),stroke volume(SV)cardiac output(CO)were measured with echocardiography. Left ventricular mass(LVM),left ventricular mass index(LVMI)and relative wall thickness(RWT)were calculated. Results LVM,LVMI,IVSTd,LVPWTd,LVESD,LVEDD,LAD,RWT in the EH+AF group were significantly greater than those in the AF alone or EH alone patients(P

Background Resveratrol has been unanimously recognized as an cardiovascular protective substance in red wine. It has been speculated that the anti-atherosclerosis effect of resveratrol is ascribed to its powerful anti-inflammatory effect. Objective To investigate the effects of resveratrol on injured human umbilical veno-endothelial cells (HUVEC) and the reactive oxygen species(ROS) production induced by TNF-? or soluble CD40L (sCD40L). Methods Cultured HUVEC were pre-incubated with resveratrol(1-50 ?mol/L) for 2 hours and then treated with TNF-?(10 ?g/L) or sCD40L?(10 ?g/L) for another 4 hours. MTT assay was used to detect proliterative activity of HUVEC. Immunofluorescence microscopy was used for determination of ROS expression. Results Both TNF-? and sCD40L impaired HUVEC proliferation (-32.7% and -26% vs control,P

Background Left ventricular hypertrophy(LVH) is a cardiovascular risk factor independent of the blood pressure. JAK/STAT pathway has been confirmed to participate in cardiac hypertrophy and hyperplasia. Our previous reports have shown that sodium tanshinone ⅡA sulfonate(STS) reversed LVH,inhibited the myocardial cells Ca2+ influx,lowered left ventricular myocardial tumor necrosis factor-?(TNF-?)and the proto-oncogene c-fos,Bcl-2,and p53 protein expression. Objective To study the effect of sodium tanshinone ⅡA sulfonate(STS) on JAK/STAT pathway in left ventricular hypertrophy(LVH) induced by abdominal aorta stenosis in rats. Methods Twenty-four 9-weeks-old rats submitted to abdominal aorta constriction,were randomized to receive STS 10 mg/(kg?d)(n=8)or sterilized distilled water (1 mL/d)(n=8),or valsartan 10 mg/(kg?d) by gavage(n=8),with age and sex matched sham operated rats(n=8) as control. HE,VG and immunohistonchemical staining were used to evaluate the myocardial fiber dimension(MFD). Expressions of JAK1 and STAT3 were assessed by using Western blot. Results Compared with the control group,pressure loaded rats had higher SBP[(117.3?8.3) vs LVH: (186.5?13.5)mmHg,P
