Correlation between serum angiotensin converting enzyme and angiotensinogen levels and pregnancy-induced hypertension and analysis of risk factors / 解剖学报

Objective To investigate the relationship between serum angiotensin converting enzyme (ACE) and angiotensinogen (AGT) and gestational hypertension syndrome (HDCP) and the risk factors of HDCP. Methods A total of 135 pregnant hypertensive patients (HDCP group) and 100 normal pregnant women as control check (CK) group were selected. Serum ACE and AGT levels were measured by ELISA, and correlation analysis was performed. The age and gestational age of the two groups, pre-pregnancy body mass index (BMI), parity, number of births, family history of hypertension, family history, education, and other general information, single factor analysis of risk factors for maternal HDCP, single factor regression analysis Statistically significant factors were all used for multivariate logistic regression analysis. Results The serum ACE level in the HDCP group (90.49±47.65) μg/L was significantly higher than that in the CK group (58.72±27.58) μg/L, P0.05, the difference was not statistically significant; single factor analysis showed; age, BMI, hypertension, family history of diabetes, ACE level was maternal (P0.05). Multivariate analysis showed: age, BMI, history of hypertension and ACE. It was a risk factor for pregnancy-induced hypertension. Conclusion ACE levels are associated with HDCP. AGT levels are not associated with HDCP. Patients with a high age, high BMI, and hypertension history have an increased risk of gestational hypertension syndrome.

Association between angiotensin converting enzyme and angiotensinogen gene polymorphisms and pregnancy-induced hypertension in Qinghai / 解剖学报

Objective To investigate the relationship between angiotensin converting enzyme (ACE) and angiotensinogen (AGT) gene expression, gene polymorphism and pregnancy-induced hypertension in Qinghai. Methods A total of 210 pregnant hypertensive patients (HDCP group) and 220 normal pregnant women (CK group) were enrolled. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect AGT M235T and ACE I/ D gene polymorphism. Results The proportions of ACE gene DD, ID, and Ⅱ in CK group were 28. 15%, 47. 73%, and 24. 09%, respectively. The HDCP group was 33. 81%, 51. 90%, and 14. 29%, respectively (P < 0. 05). The frequency distribution of ACE I/ D polymorphic alleles I and D was different between HDCP group and CK group(P<0. 05). D allele frequency was higher in HDCP group than in CK group (

Chemical constituents of stems and leaves of Salvia yunnanensis and their anti-angiogeneic activities / 中国中药杂志

Present study was focused on the chemical constituents of the stems and leaves of Salvia yunnanensis C . H. Wright and their anti-angiogeneic activities. The compounds were isolated by column chromatography over silica gel and Sephadex LH-20, and other isolation techniques. Their structures were elucidated on the basis of spectral analysis and chemical evidences. Their anti-angiogeneic activities were evaluated by the chicken chorioallantoic membrane (CAM) neovascularisation model. Seven compounds were separated and identified as ( + ) -spathulenol( 1), 5,7,4'-trihydroxyflavanone(2) , beta-amyrin(3), 3 beta-hydroxy-12-ursene(4), 2alpha,3 beta-dihydroxyursa-12-en-28-oic acid(5), ursolic acid (6) and 3-oxo-12-ursen-28-oic acid (7). Compounds 1, 2, 5 and 6 were obtained from this plant for the first time. Compounds 5 (an oleanane compound) and 6 (an ursane compound) could inhibit angiogenesis significantly in a dose-dependent manner.
