Advances in research on the central mechanism of hypertension / 西安交通大学学报(医学版)

ABSTRACT

ABSTRACT:Hypertension,the first risk factor for stroke and coronary heart disease in the Chinese population, seriously endangers people’s health.At present,China has more than 270 million people with hypertension and an annual increase rate of 1 0 million people.Then how to improve prevention and treatment of hypertension has become an urgent need to solve major medical and social problems.In the past,research on hypertension mainly focused on the peripheral area,while recent research has shown that the central regulation plays an important role in the development of hypertension. Hypothalamic paraventricular nucleus (PVN ), which plays a key role in maintaining cardiovascular activity, can directly control the sympathetic preganglionic neurons and regulate peripheral sympathetic nerve activity,thus being closely related to the development of hypertension.Research in recent years shows that the comprehensive effects of proinflammatory cytokines (PIC ),reactive oxygen species (ROS),renin-angiotensin system (RAS),neurotransmitter (NT)and nuclear factorκB (NF-κB)are involved in the pathogenesis of hypertension.However,it is unclear how these neurohormones in PVN are activated,how they interact with each other and what role they play in the regulatory mechanism of hypertension.Therefore,the key focus of this research is to explore the impact of activated neurohormones in PVN on hypertension.This study will provide new content for the study on hypertension.
