The changes of plasma 8-iso-prostaglandin F2αand serum C-reactive protein levels in patients with obstructive sleep apnea-hypopnea syndrome

Objective To investigate the plasma 8-iso-prostaglandin F2α(8-iso-PGF2α and the serum C-re-active protein(CRP) levels in patients with obstructive sleep apnea-hypopnea syndrome(OSAHS) with and without hypertension(OSAHS + HT),and to explore the changes of pathophysiology in patients with OSAHS and the patho-genesis of OSAHS + HT. Methods All observed subjects were divided into 3 groups: control group (n=20),OS-AHS group(n=19),OSAHS + HT group (n=21). Plasma 8-iso-PGF2αand serum CRP concentrations levels were measured by ELISA and were compared. Results The plasma 8-iso-PGF2αand serum CRP levels,were higher in OSAHS patients than those in control subjects [(11.08±3.26)μg/L vs (7.49±2.10)μg/L,P<0.01;(1.75±0.82) mg/L vs (0.52±0.26 ) mg/L,P<0.01],and were higher in OSAHS + HT group than those in control group [14.84±3.43)μG/L vs(11.08±3.26)μg/L,P<0.01 ;(3.13±1.06)mg/L vs(1.75±0.82)mg/L,P<0.01]. Conclusions Oxidative stress and inflammation in OSAHS patients are increased,which are involved in the devel-opment of OSAHS associated hypertension.

脂质过氧化反应与阻塞性睡眠呼吸暂停低通气综合征及其合并高血压

阻塞性睡眠呼吸暂停低通气综合征（obstructive sleep apneahypopnea syndrome,OSAHS）是指由于各种原因所致上气道部分或完全阻塞,使睡眠过程中呼吸时上气道阻力增加,呼吸表浅或停止,反复发生低氧、高碳酸血症,导致白天嗜睡,心、脑、肺、血管并发症乃至多脏器损害的临床综合征,OSAHS严重影响患者的生活质量和寿命。OSAHS与高血压病的发病密切相关。脂质过氧化反应是指自由基与细胞膜上的不饱和脂肪酸（RH）发生氧化反应,生成对细胞具有毒性作用的过氧化物（ROOH）。自由基及其介导的脂质过氧化反应对机体可产生多种损伤,导致多种疾病,它的发生发展过程及损伤机制与OSAHS及其合并高血压病的发生密切相关。本文将近年来有关脂质过氧化反应与OSAHS及其合并高血压的研究进展做一综述。
