Correlations between changes in hematological indices of mothers with preeclampsia and umbilical cord blood of newborns.
Preeclampsia is a condition that might severely impact the health of mothers and their newborns. The aim of this investigation is to examine hematological parameters in mothers with preeclampsia and umbilical cord blood. Eighty preecalmptic mothers were recruited in the study. ⋯ In addition, results showed significant and positive correlations between preeclamptic mothers and their newborn in Hb (r2 = 0.075, P < 0.05), PCV (r2 = 0.084, P < 0.01), MCV (r2 = 0.077, P < 0.05), MCHC (r2 = 0.115, P < 0.01), RBC (r2 = 0.086, P < 0.01) and retics (r2 = 0.306, P < 0.01). In conclusion, changes in several hematological parameters associated with preeclampsia were correlated in affected mothers and their newborns. Such biomarkers can be used to predict pregnancy outcomes in women with preeclampsia.

Descriptive study of the relationship between the subclinical carotid disease and biomarkers, carotid femoral pulse wave velocity in patients with hypertension.
Carotid intima-media thickness (cIMT) is a significant early prediction signal for preclinical atherosclerosis. Plasma homocysteine (Hcy) level is an independent risk factor for cardiovascular diseases. Pulse wave velocity (PWV), an index of arterial stiffness (AS), has showed its value in the evaluation of AS in vascular-related diseases. The data regarding the relationships between cIMT and other indices of vascular damage are limited and partly controversial. We aim to investigate the relationships between cIMT and other indices of vascular damage such as Hcy and carotid femoral PWV (CF-PWV). ⋯ Increased carotid femoral PWV and elevated plasma Hcy levels are associated with subclinical carotid disease in hypertensive patients. CF-PWV independently predicted subclinical carotid plaque in the patients with hypertensive. While, there is insufficient evidence for Hcy in predicting plaque incidence.

Estimation of salt intake and sodium-to-potassium ratios assessed by urinary excretion among Japanese elementary school children.
Dietary salt intake is largely responsible for the increase in blood pressure with age. It is important to start effective prevention approaches during childhood. In this study, we estimated salt intake and sodium-to-potassium (Na/K) ratios assessed by urinary excretion among elementary school children in Kyoto, Japan. ⋯ The median urinary Na/K ratio (mEq/mEq) was 4.5. Multivariate linear regression model analysis revealed a significant negative correlation between fruit consumption and urinary Na/K ratio (p = 0.04). These results suggest that the high sodium intake and the high Na/K ratios occur among Japanese elementary school children, and that the urinary Na/K ratio in children may be reduced by the daily consumption of fruit.

Inhibitory effects of candesartan on KCa3.1 potassium channel expression and cell culture and proliferation in peripheral blood CD4+T lymphocytes in Kazakh patients with hypertension from the Xinjiang region.
Increasing evidence confirms that potassium channels are essential for lymphocyte activation, suggesting an involvement in the development of hypertension. Moreover, chronic inflammation is regarded as a direct or indirect manifestation of hypertension, highlighting the theoretical mechanisms. In this study, we investigated changes in KCa3.1 potassium channel expression in the blood of hypertensive and healthy Kazakh people in north-west China. ⋯ Increase in functional KCa3.1 channels expressed in CD4+ T lymphocytes of Kazakh patients with hypertension was blocked by candesartan, providing theoretical support for hypertension treatment at the cellular ion channel level. Candesartan may potentially regulate hypertensive inflammatory responses by inhibiting T-lymphocytic proliferation and KCa3.1 potassium channel expression in CD4 + T lymphocytes.

Positive association between blood pressure (BP) and uric acid is evident, but specific effect size of serum uric acid (SUA) at different levels on BP is unclear, and interaction effect of SUA with other metabolic factors on BP was rarely reported. A cross-sectional study was conducted by making use of data from an epidemic investigation. A total of 3658 subjects were enrolled in our data analysis. ⋯ This difference was not observed in DBP and females. Interaction effects between SUA and BMI, TG, FPG on BP were discovered. In conclusion, higher level of SUA has a stronger effect on BP and other metabolic factors: FPG, TG, and BMI could strengthen the effect of SUA on BP.
