BACKGROUND: Sleep disorders have been found to be associated with hypertension in both cross-sectional and longitudinal epidemiological studies. Tetrandrine, a major component of Stephania tetrandra, is well known as an antihypertensive agent. The anti-hypertension mechanism mainly relies on its L-type calcium channel blocking property. In the previous study, tetrandrine revealed both anti-hypertension and hypnotic effects in spontaneously hypertensive rats (SHRs). PURPOSE: This study aims to elucidate whether the antihypertensive mechanism of tetrandrine in SHRs is relevant to its hypnotic effect...

PURPOSE OF REVIEW: Obstructive sleep apnea (OSA) is a highly prevalent condition that has been associated with cardiovascular morbidity and mortality, impaired glucose metabolism and daytime functional impairment. Compared with nonrapid eye movement sleep, rapid eye movement (REM) sleep is associated with higher sympathetic activity and cardiovascular instability in healthy individuals and more so in patients with OSA. RECENT FINDINGS: Recent studies have indicated that REM OSA is independently associated with prevalent and incident hypertension, nondipping of nocturnal blood pressure, increased insulin resistance and impairment of human spatial navigational memory...

BACKGROUND: Obesity has been found to be a predictor of left ventricular hypertrophy (LVH). However, studies which divide obesity into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) to study the effect of obesity on LVH have been rare. The present study aims to make clear the effects of various obese phenotypes and metabolic abnormalities on LVH. METHODS: A total of 10,804 participants were involved in this cross-sectional study. "Obesity" and "metabolically healthy" were defined as BMI ≥ 25kg/m(2) and having none of the metabolic factors respectively...
