既往研究提示颠倒的昼夜血压节律可能与体位性低血压和（或）进展性糖尿病肾病相关，然而有关非胰岛素依赖型糖尿病（ＮＩＤＤＭ）病人与昼夜血压节律关系的长期随访研究很少见。本研究通过对正常和颠倒的昼夜血压节律ＮＩＤＤＭ病人的长期随访，来了解其预后并确定颠倒的昼夜 Previous studies have suggested that reversed circadian rhythm may be associated with orthostatic hypotension and / or progressive diabetic nephropathy, whereas long-term follow-up studies of the relationship between circadian rhythm and nocturnal non-insulin-dependent diabetes mellitus (NIDDM) are rare. In this study, long-term follow-up of normal and up-circulated circadian rhythm NIDDM patients was used to understand their prognosis and to determine reversed day and night
