Oncotarget:睡眠呼吸暂停综合征与端粒缩短相关

2016-10-30 MedSci MedSci原创

老年化与阻塞性睡眠呼吸暂停综合征(OSAS)的患病率增加和端粒的缩短相关。众所周知,OSAS相关因素的刺激,可导致细胞的衰老的加速。因此,本研究的目的是比较OSAS患者和对照组白细胞端粒长度(LTL),以及验证LTL和睡眠参数的相关性。研究者从EPISONO中928患者提取DNA,通过实时定量聚合酶链反应检测LTL。对所有患者进行一个全夜多导睡眠图。OSAS患者比对照组LTL明显减小。结果表明,L

老年化与阻塞性睡眠呼吸暂停综合征(OSAS)的患病率增加和端粒的缩短相关。众所周知,OSAS相关因素的刺激,可导致细胞的衰老的加速。因此,本研究的目的是比较OSAS患者和对照组白细胞端粒长度(LTL),以及验证LTL和睡眠参数的相关性。

研究者从EPISONO中928患者提取DNA,通过实时定量聚合酶链反应检测LTL。对所有患者进行一个全夜多导睡眠图。OSAS患者比对照组LTL明显减小。结果表明,LTL与和下列变量呈负相关:睡眠呼吸暂停低通气指数、呼吸紊乱指数、入睡后减饱和指数和醒来。LTL与睡眠效率、总睡眠时间、基础、最高和最低血氧饱和度呈正相关。最后发现,即使校正了性别、年龄,受教育年限、体重指数、糖尿病卒中和心脏病发作OSAS严重程度与较短的LTL相关。

总之,研究表明,OSAS和LTL存在一定的相关性,端粒缩短与OSAS严重程度之间存在显著的相关性。

Circulation: 经皮冠状动脉介入术后,睡眠呼吸暂停综合征可致不良心脑血管事件

背景:缺乏数据的大型队列研究冠状动脉疾病的患者,阻塞性睡眠呼吸暂停(OSA)的预后意义。研究者假设,经皮冠状动脉介入治疗的患者,OSA预测随后的主要不良心脑血管事件(MACCEs)。方法和结果:睡眠和支架的研究是涉及5个国家的一项前瞻性,多中心登记的研究,患者为经皮冠状动脉介入成功治疗。在2011年12月至2014年4月间,共招募1748名符合条件的患者进行前瞻性研究。1311名患者在经皮冠状动脉
