阻塞性睡眠呼吸暂停低通气综合征患者糖、脂代谢紊乱的研究

目的通过观察OSAHS患者血清内脂素、血糖、甘油三酯水平的变化,探讨糖脂代谢紊乱与0sAHS的相关性。方法选择OsAHS患者45例,轻度OSAHS患者组20例,中重度0sAHS患者组25例。选择正常对照组20例。采取酶联免疫吸附法（ELISA）测定空腹血清内脂素的浓度,常规检测血糖、甘油三酯。结果轻度及中重度OSAHS组与正常对照组比较,血清内脂素水平均升高（F=38．59,P〈0．01）;中重度OsAHS组与轻度OSAHS组比较,血清内脂素水平升高（t=2．93,P〈0．01）。轻度OSAHS组与正常对照组比较,甘油三酯水平升高（t=2．97,P〈0．01）。血糖升高不明显（t=1．58,P〉O．05）;中重度0sAHS组与正常对照组比较,甘油三酯、血糖水平均升高（t=4．26,3．01,P值均〈0．01）。中重度0sAHs组与轻度0sAHS组比较,甘油三酯、血糖水平升高（t=3．12,2．93,P值均〈O．01）。血清内脂素与反映睡眠呼吸严重程度的指标有相关性（r=0．83,0．615,0．715,0．642,0．710,P值均〈O．01）。结论0sAHS患者存在血清内脂素、血糖、甘油三酯水平的异常,且与OSAHS的病情严重程度相关,说明0SAHS与糖脂代谢紊乱具有相关性。     

重叠综合征与肺动脉高压

重叠综合征(overlap syndrome,OS)是指阻塞性睡眠呼吸暂停低通气综合征(Obstructive Sleep Apnea-Hypopnea Syndrome,OSAHS)合并慢性阻塞性肺疾病(Chronic Obstructive Pulmonary Disease,COPD),二者的发生有无内在联系研究结果尚不一致。     

应用胰岛素强化治疗伴高血糖的重症肺炎

重症肺炎激发的应激反应会导致机体神经内分泌及代谢功能的紊乱,血糖升高就是其典型的表现之一.而高血糖又会加重感染,损害组织和脏器功能,使病情恶化[1-4]."感染-代谢紊乱-血糖升高-加重病情"呈恶性循环.因此抗炎、对症、支持等治疗的同时,也应重视神经体液和内分泌代谢等改变的调节和干预.本研究对我院收治的伴高血糖的重症肺炎患者行胰岛素治疗并疗效评价.

阻塞性睡眠呼吸暂停低通气综合征患者血清瘦素水平及与胰岛素抵抗的相关性研究

目的探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者血清瘦素水平及与胰岛素抵抗的相关性.方法选择OSAHS患者和健康者(对照组)各50例,分别行多导睡眠图检查,并测定空腹血糖、瘦素和胰岛素水平.结果 (1)OSAHS患者组的血清瘦素、空腹胰岛素水平及胰岛素抵抗指数(HOMA-IR)与对照组间差别均有显著性意义(P＜0.01).(2)OSAHS患者组血清瘦素水平、空腹胰岛素水平、HOMA-IR均与呼吸暂停低通气指数(AHI)、呼吸障碍事件最长时间、微觉醒指数呈正相关,与最低血氧饱和度呈负相关.(3)OSAHS患者血清瘦素水平与空腹胰岛素水平、HOMA-IR呈正相关.结论 (1)OSAHS患者的空腹血清瘦素水平升高,且与OSAHS病情严重程度有关.(2)OSAHS独立于肥胖等混淆因素与胰岛素抵抗存在相关性.(3)OSAHS患者血清瘦素水平与胰岛素抵抗存在相关性.

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.
