高血压是一种多因素导致的疾病,盐的摄入与高血压的发生密切相关,高盐摄入已成为高血压的一个独立危险因素。高盐负荷可作用于中枢神经系统引起交感神经活性增加,参与高血压的形成[1-2],因此中枢交感神经系统过度激活参与盐敏感性高血压发病机理已经引起了广泛的重视。笔者就盐 Hypertension is a multifactorial disease, salt intake is closely related to the occurrence of hypertension, high salt intake has become an independent risk factor for hypertension. High salt stress can cause the increase of sympathetic activity in the central nervous system, which is involved in the formation of hypertension [1-2]. Therefore, the central nervous system over-activation involved in the pathogenesis of salt-sensitive hypertension has attracted wide attention. I salt
