阻塞性睡眠呼吸暂停低通气综合征与男性不育症

目的 探讨阻塞性睡眠呼吸暂停低通气综合征（OSAHS）与男性不育的关系。方法 对重度OSAHS患者16例使用持续气道正压（CRAP）呼吸机治疗前后进行检查，其内容包括精液及性激素水平，并随访其生育情况。结果 随访的16例患者使用CR岬机治疗后有11例生育正常小儿，且精液检查及激素水平测定均较治疗前有明显好转，表现为精子浓度、精子活力较治疗前明显增加，去氢睾酮及黄体生成素水平均较治疗前明显增高，治疗前后相比差异有显著性（P〈0．05）。结论 OSAHS可能是男性不育的原因之一。     

阻塞性睡眠呼吸暂停低通气综合征患者血浆抵抗素和脂联素水平与胰岛素抵抗的相关研究

Objective To explore relationship between resistin'adipenectin and insulin resistance(IR) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Based on polysomnography (PSG) and disease history ,68 patients were divided into three groups: mild ( L, n = 24 ), moderate ( M, n = 13 ), severe ( S, n = 31 ) OSAHS, and normal control ( n = 20 ). Fasting serum glucose, insulin, lipoids, resistin and adipanectin were measured. HOMA-IR was calculated, the correlation between HOMA-IR and resistin, adiponectin, lipoids, body mass index, waist-to-hip ratio, apnea-hypopnea index ( AHI), the lowest saturation of blood oxygen ( LSaO2) and the per-centage of total sleep time spent with an oxygen saturation less than 90% (T90) were analysed. Results The levels of serum resistins in each OSAHS group were (8.04 ±2. 14), ( 10.85±4.89 ), ( 13.34±3.52 )mg/L, and were sig-nificantly higher than those in control group ( 9.49 ± 2.40) mg/L ( P < 0.05 ), S were significantly higher than L (P<0.05) ;The levels of serum adiponectin of OSAHS groups were(6. 21 ± 1.74), (4. 19±1.80), (2.26± 1.17 ) mg/L, and were significantly lower than those in control group(9.49±2.40) mg/L (P < 0.05 ), and the inter-group differences were statistically significant (P <0. 05). HOMA-IR of M and S were(4.07±0.97), (5.61± 2.26) significantly higher than those of L and control group( 1.57 ±0. 58 ), (2.47 ±1.52 ) ( P < 0.05 ), and inter-group differences between M and S were statistical significant( P < 0.05 ). Spearman correlation analysis showed that HOMA-IR was significantly positive correlated with resistin, total cholesterol, triglyceride, body mass index,waist-hip rafio,AHI,T90( r =0. 794,0.438,0. 430,0. 351,0. 456,0.775,0.624 ,P <0.01 ) ,negative with adiponectin, LSaO2 (r=-0.563, -0.623 ,P <0.01 ). Partial correlation analysis showed that after the effect of adiponeetin and resis-tin were controlled,HOMA-IR was significant positive correlation with T90 and AHI(r =0.231,0.358 ,P <0.05 ). Multiple stepwise regression analysis showed that, to HOMA-IR, resistin and AHI were the most significant impact factors (R2 =0.613,F=69.810,P<0.01). Conclusions HOMA-IR is significantly positively correlated with the severity of OSAHS,independent of the blood lipids, body mass index, waist-hip ratio, resistin, adiponectin and other factors;the effects of blood lipids,body mass index,waist-hip ratio and other factors on HOMA-IR probably depend on resistin and adiponectin;AHI and plasma resistin level may determine the level of insulin resistance in patients with OSAHS.     

阻塞性睡眠呼吸暂停低通气综合征患者血浆抵抗素和脂联素水平与胰岛素抵抗的相关研究

目的 探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者血浆抵抗素和脂联素水平与胰岛素抵抗程度的相关性.方法 根据整夜多导睡眠监测(PSG)和既往病史将68例OSAHS患者分为轻度(24例)、中度(13例)、重度(31例)OSAHS组,并设正常对照组(20例).检测各组空腹血糖、胰岛素、血脂、抵抗素、脂联素水平,计算稳态模型胰岛素抵抗指数(HOMA-IR),并分析HOMA-IR与抵抗素、脂联素、血脂、体重指数、腰臀比、睡眠呼吸暂停低通气指数(AHI)、最低血氧饱和度(LSaO2)、夜间血氧饱和度低于90%的时间占总睡眠时间的百分比(T90)等指标的相关性.结果 轻、中、重度OSAHS组的抵抗素水平[分别为(8.04±2.14)、(10.85±4.89)、(13.34±3.52)mg/L]均明显高于正常对照组[(5.14±1.94)mg/L]差异均有统计学意义(P均<0.05),且OSAHS重度组明显高于轻度组(P<0.05).脂联素在OSAHS轻度[(6.21±1.74)mg/L]、中度[(4.19±1.80)mg/L]、重度[(2.26±1.17)mg/L]组的水平均明显低于正常对照组[(9.49±2.40)mg/L],且OSAHS各组间差异均有统计学意义(P均<0.05).OSAHS中、重度组的HO-MA-IR(4.07±0.97、5.61±2.26)明显高于OSAHS轻度组(1.57±0.58)和正常对照组(2.47±1.52),且OS-AHS中、重度组间差异也有统计学意义(P均<0.05).Spearman相关分析显示HOMA-IR与抵抗素、总胆固醇、甘油三酯、体重指数、腰臀比、AHI、190有显著正相关(r值分别为0.794、0.438、0.430、0.351、0.456、0.775、0.624,P均<0.01),与脂联素、LSaO2有显著负相关(r值为-0.563、-0.623,P均<0.01).偏相关分析显示控制脂联素和抵抗素影响后,HOMA-IR与190、AHI有显著正相关(r值分别为0.231、0.358,P均<0.05).多元逐步回归分析显示AHI和抵抗素为影响HOMA-IR的最显著因素(R2=0.613,F=69.810,P<0.01).结论 OSAHS患者的HOMA-IR与OSAHS严重程度具有显著正相关,且独立于血脂、体重指数、腰臀比、抵抗素和脂联素等因素的影响;血脂、体重指数、腰臀比等因素可能通过对抵抗素和脂联素的作用影响HOMA-IR;AHI和血浆抵抗素水平可能成为判断OSAHS患者胰岛素抵抗水平的重要生物学标志.

阻塞性睡眠呼吸暂停低通气综合征与高血压的关系

目的:探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)与高血压的关系。方法:对本中心多导睡眠监测(PSG)的353例患者进行血压测量,并分析患者呼吸紊乱指数(AHI)、夜间最低血氧饱和度(SaO2 min)、体重指数与高血压患病率及血压升高程度的关系。结果:以AHI分组,各组间高血压患病率比较,P<0.001。重度SaO2 min与其他各组间高血压患病率比较P<0.001。AHI与血压的高低呈正相关(P<0.001),SaO2 min与血压的高低呈负相关(P<0.001)。结论:OSAHS作为高血压发病的危险因素,其AHI指数、夜间低氧程度均与高血压患病率相关。
