110 g/m2 in females.④Logistic regression analysis was conducted taking sex, age, body mass index, body surface area, blood pressure, blood fat level, plasma aldosterone concentration and aldosterone synthase as independent variables while LVEDD, LVM or LVH as dependent variables respectively. RESULTS: All 68 patients were involved in the result analysis.①Among 68 cases of essential hypertension, there were 36 cases for TT genotype, 28 cases for CT genotype and 4 cases for CC genotype. And they were divided into TT genotype group and CT+CC genotypes group.②Compared with those subjects with TT genotypes, hypertensive subjects with CT+CC genotypes had a higher LVEDD, LVM and LVM index [(50.2?3.2) mm, (48.1?3.2) mm; (220.8?34.4) g, (197.4?35.5) g; (123.4?21.5) g/m2, (107.2?15.9) g/m2; t =2.73, 2.74, 3.54, P

Objective: To evaluate the predictive value of plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) on short term prognosis in patients with acute coronary syndrome (ACS). Methods: Plasma NT-proBNP levels were measured in ACS patients within 24 h after admission with ELISA method. The 600 ACS patients were divided into two groups: event group （n=108）and no-event group （n=492）according to occurrence of cardiovascular events（including cardiac death, cardiac shock and heart failure）, The NT-proBNP levels were compared between two groups. Single factor and multiple factor Logistic regression analyses were used to evaluate if NT-proBNP was an independent predictor for short term prognosis. Results: The plasma NT-proBNP levels of event group were significantly higher than those of no-event group [1361.2 (965.3, 2088.6) pmol/L vs.605.7 (274.5, 1177.8) pmol/L, p<0.01]. Multiple factor Logistic regression analyses demonstrated that plasma NT-proBNP was an independent predictor for short term prognosis (OR=1.000, p<0.01) in ACS patients. Conclusion: Plasma NT-proBNP was an independent predictor for short term prognosis in ACS patients.

AIM: To evaluate the role of human angiotensin Ⅱ(AngⅡ) type Ⅰ receptor (AT1R) antisense cDNA (ahAT1) on migration of cultured artery smooth muscle cells (VSMCs). METHODS: Two recombinant adenoviral vectors, Ad/CMV. ahAT1 containing full length antisense cDNA targeting to human AT1R mRNA, and Ad/CMV.LacZ containing LacZ called report gene, were constructed by orientation clone technology and homologous recombination, and then were used to transfect VSMCs in vitro. AT1R expression detected by RT-PCR and immunohistochemistry, and migration of VSMCs measured by Boyden's Chamer methods, were compared between transfected and non- transfected VSMCs. RESULTS: Forty-eight hours after Ad/CMV. ahAT1 transfection, the level of AT1R mRNA decreased markedly (50% of control group), and AT1R protein expression was significantly less (P
