Angiotensin I converting enzyme (ACE) gene is one of the most-studied candidate genes related to essential hypertension (EH). Pulse pressure (PP) may reflect vascular stiffness, especially in patients with EH, and has been used to predict EH. Previous evidence has indicated that obesity is a traditional risk factor of hypertension. The aim of the present study was to investigate the interaction between the obesity status and ACE gene polymorphisms on the development of high level of PP. A total of 1980 adults (1024 hypertensive and 956 normotensive) were included in this study and genotyped for ACE gene polymorphisms...

Endothelial inflammation caused by tobacco smoking is widely considered as a pathogenic factor in many vascular diseases. Drugs such as atorvastatin were found to be an effective treatment in smoking-dependent vascular diseases, but the underlying mechanism is still unclear. Here, we investigated the mechanism of atorvastatin resisting endothelial inflammation caused by tobacco smoking. Firstly, isolated human umbilical vein endothelial cells (HUVECs) were divided into normal control group, cigarette smoking extract (CSE) group, and atorvastatin (AS)+CSE group...

Central systolic blood pressure (cSBP) decreases after a meal or glucose challenge, but this response is impaired in obesity-related disorders. We investigated whether aerobic exercise training improves cSBP regulation during an oral glucose tolerance test (OGTT) in overweight/obese men. Thirteen overweight/obese men and six normal-weight men (as an alternative comparison instead of a no-exercise group) completed a 12-week aerobic exercise training program. Before and after the program, cSBP (i.e., radial second systolic pressure) was measured using an applanation tonometry at fasting and both 60 min and 120 min after 75 g glucose loading...
