根据近来研究,糖尿病(DM)中高血压的可能发病机理有: 一、与高血糖有关的因素:(1)高血糖促进糖在近曲小管重吸收,引起钠的重吸收,同时高胰岛素血症(HI)也促进钠在肾小管重吸收,从而增加总体钠成分(通常增加10％)使细胞外液扩张;(2)高血糖使血浆渗透压增高,循环血容量增加;(3)高浓度葡萄糖可促进 According to recent studies, the pathogenesis of hypertension in diabetes mellitus (DM) are as follows: First, the factors associated with hyperglycemia: (1) hyperglycemia promote sugar reabsorption in the proximal tubule, causing sodium reabsorption, while hyperinsulinemia (HI) also promotes reabsorption of sodium in the renal tubules, thereby increasing the overall sodium component (usually by 10%) to disrupt extracellular fluid; (2) hyperglycemia increases plasma osmolality and increases circulating blood volume; (3) Glucose can promote
