Comparison of adiposity indices in relation to prehypertension by age and gender: A community-based survey in Henan, China.

Background: To compare the efficiency of bioelectrical indices (visceral fat index [VFI], percentage body fat [PBF]) and anthropometric indices (body mass index, waist circumference, waist-to-height ratio, a body shape index ) in the relation to prehypertension (120-139/80-89 mm Hg) among the Chinese population.

Methods: Using stratified multistage random sampling method, a general population-based sample of 11 175 adults in Henan province were selected from 2013 to 2015. The individuals were divided into three categories by blood pressure levels: normotension (<120 and 80 mm Hg), stage 1 prehypertension (120-129/80-84 mm Hg) and stage 2 prehypertension (130-139/85-89 mm Hg).

Association between resting heart rate and hypertension in Chinese with different waist-to-height ratio: a population-based cross-sectional study.

Elevated resting heart rate (RHR) and obesity are important risk factors for hypertension. However, studies are rare on the combined impact of RHR and obesity on prehypertension and hypertension. This study aimed to investigate the association between RHR and hypertension with different waist-to-height ratio (WHtR) in Chinese.

Stroke and (or) myocardial infarction attributable to modifiable risk factors in Henan, China.

Estimating population attributable risks of potential modifiable risk factors for stroke and (or) myocardial infarction may be useful for planning cardiovascular disease (CVD) preventive strategies. A population of 17,292 adults aged 18 years and older from a cross-sectional survey was included in the study. The binary logistic regression was used to evaluate the association between risk factors with disease events, then population attributable fraction according to prevalence and odds ratios were calculated to identify and compare the effects at different subpopulations.

miR-106b promotes cell invasion and metastasis via PTEN mediated EMT in ESCC.

MicroRNA (miR)-106b serves an essential function in a variety of human cancer types, particularly in the process of invasion and metastasis. However, the function and mechanism of miR-106b in the invasion and metastasis of esophageal squamous cell carcinoma (ESCC) has remained elusive. In the present study, it was demonstrated that miR-106b was upregulated in ESCC tissues and cell lines.
