目的:观察血清同型半胱氨酸(Hcy)水平在阻塞性睡眠呼吸暂停低通气综合征(OSHAS)及冠心病(CHD)患者中的变化和作用。方法:收集临床确诊CHD、OSAHS、CHD+OSAHS患者各30例,分别为CHD组、OSAHS组和CHD+OSAHS组。平行检测各组血清Hcy水平及睡眠呼吸监测指标:呼吸暂停低通气指数(AHI)、夜间最低血氧饱和度(SaO2)及平均SaO2,比较各组Hcy水平的差异以及Hcy水平与睡眠呼吸监测指标的相关性。并与30例体检健康者(健康对照组)对比分析。结果:(1)血清Hcy水平:三病例组明显高于健康对照组(P0.01),CHD+OSAHS组明显高于CHD组和OSAHS组(P0.01),CHD组与OSAHS组比较,差异无统计学意义(P0.05)。(2)病例组血清Hcy水平与AHI呈正相关(r=0.64,P0.01),与夜间平均SaO2和夜间最低SaO2均呈负相关(r分别为-0.64、-0.65,P0.01)。结论:血清Hcy水平升高与OSAHS患者SaO2减低有关,可能有利于CHD的发生与发展。 相似文献

目的探讨新生儿黄疽治疗前后血清转铁蛋白(TRF)、C反应蛋白(CRP)及胆红素水平的变化及意义。方法选择2015年1月至2017年3月于医院生产的140例新生儿黄疽患儿作为研究对象,根据黄疽类型分为病理性黄疸组(n=86)与生理性黄疽组(n=54),并选取同期于医院生产的50例正常健康新生儿作为对照组,均采血检测血清TRF、CRP、总胆红素(TBiL)及直接胆红素(DBiL)水平,病理性黄疸组于治疗前后均检测上述指标的变化,分析TRF、CRP与胆红素水平变化的关系。结果生理性黄疸组、病理性黄疸组血清TBiL、DBiL均高于对照组,TRF低于对照组,病理性黄疸组血清CRP、TBiL、DBiL又高于生理性黄疽组,TRF低于生理性黄疽组(P<0.05);治疗后,病理性黄疽新生儿TRF上升,CRP、TBiL、DBiL水平降低,与治疗前比较差异有统计学意义(P<0.05);CRP与新生儿病理性黄疽TBiL、DBiL呈正相关(P<0.05),TRF与TBiL及DBiL均呈负相关(P <0. 05)。结论新生儿黄疽患儿TRF水平较低,CRP水平较高,且病理性黄疽组TRF低于生理性黄疽组,CRP高于生理性黄疽组,两者均与新生儿病理性黄疸组TBiL、DBiL水平存在相关性,可作为病理性黄疽病情评估及疗效预测的依据。 相似文献

目的 探讨不同性别的OSAHS患者的睡眠质量对血压的影响。方法 选择2014年5月~2017年12月我院通过整夜多导睡眠图监测确诊为OSAHS的患者158例,将以上患者依据分为高血压组53例和正常血压组105例,高血压组进一步分为高收缩压组33例,高舒张压组43例。比较各组男性患者与女性患者的AHI指数,睡眠质量参数与血压的关系。结果 相较于女性,男性患者的AHI指数能预测高血压组和高舒张压组(P<0.05);睡眠质量和高AHI之间的相关性,男性远高于女性(P<0.05),而没有AHI的影响,睡眠质量与男女的血压之间无显著关联(P>0.05)。结论 男性患者比女性患者的舒张压更高,睡眠质量更差,这可能是引起男性OSAHS患者的舒张压升高的原因。 相似文献

Study Objectives:
To determine whether fixed-pressure or variable-pressure CPAP was preferred by patients and gave better outcomes in patients with the obstructive sleep apnea/hypopnea syndrome (OSAHS).Design:
Randomized blinded cross-over trial with 6 weeks of fixed and 6 weeks of variable-pressure CPAPSetting:
Sleep centerPatients:
200 consecutive consenting CPAP naive patients with daytime sleepiness and >15 apneas + hypopneas/h after an attended auto-CPAP titration night.Interventions:
CPAP therapy using the same device (Autoset Spirit) set for 6 weeks in fixed pressure mode and for 6 weeks in variable pressure mode, the order of therapies being randomized.Measurements and Results:
All measurements were recorded at the end of each limb by a researcher blind to treatment. These included symptoms, Epworth Score, CPAP usage, objective sleepiness by modified Osler test, vigilance and health related quality of life. A total of 181 of 200 patients completed the study. At the end of the study, patients expressed no significant difference in the primary outcome, patient preference, 72 patients preferring fixed and 69 preferring variable-pressure CPAP. Epworth score was lower on variable (9.5, SEM 0.4) than fixed-pressure CPAP (10.0, SEM 0.3; P = 0.031). Mean CPAP use was higher on variable (4.2, SEM 0.2 h/night) than fixed-pressure CPAP (4.0, SEM 0.2 h/night; P = 0.047). There were no other significant differences between treatments.Conclusions
This study shows no difference in patient preference and only a marginal benefit of variable over fixed-pressure CPAP in OSAHS in terms of subjective sleepiness and CPAP use. The clinical value of this difference remains to be determined.Clinical Trial Information:

Objective Investigate the clinical features and the blood pressure (BP) pattern of the phenotype of excessive daytime sleepiness (EDS) in OSAHS.Methods A total of 508 Chinese adults with suspected OSAHS were referred to our sleep laboratory from October 2009 to May 2012. On the same night of polysomnography (PSG), the levels of blood pressure were measured before sleeping (bedtime BP) and immediately after waking up in the next morning (morning BP). EDS was recognized as Epworth Sleepiness Scale (ESS)≥9. Subjects were classified into four groups based on the apnea-hypopnea index (AHI) from PSG as follows: control (simple snoring) group (control, n=104) with AHI<5; mild group (mild, n=89) with AHI≥5 and <15; moderate group (moderate, n=70) with AHI≥15 and<30; and severe group (severe, n=245) with AHI ≥30. The differences and correlations between BP and PSG parameters in EDS and non-EDS group of OSAHS patients were analyzed.Results In all subjects, ESS was positively correlated with morning diastolic blood pressure (DBP), Mean arterial pressure (MAP) and bedtime DBP (r=0.144, 0.102 and 0.114, respectively, each P value<0.05). In OSAHS patients, ESS was only positively correlated with morning DBP (r=0.137, P<0.05). OSAHS patients with EDS phenotype were younger and were more likely to have the symptom of waking up feeling tired (36.1% vs. 23.2%, p=0.023), who had lower MSaO2, longer SIT90 (the ratio of time of SpO2 below 90% in total sleep time) and higher DBP (bedtime as well as morning). In patients with AHI≥15, ESS was correlated positively with both bedtime and morning DBP after controlling the confounding effects of age, sex, BMI, AHI and nadir nocturnal oxygen saturation( r=0.126,0.143, respectively, both P values<0.05). And in OSAHS patients of EDS phenotype, the bedtime DBP, bedtime MAP, morning DBP, and morning MAP were 3~5 mm Hg higher than that in patients of non-EDS phenotype(P<0.05). In the moderate and severe OSAHS group, patients with EDS phenotype were younger and had a lower mean blood oxygen saturation (MSaO2), longer time of SpO2 below 90% and higher SIT90 than patients with non-EDS phenotype (P<0.05). In hypertensive OSAHS patients, patients with EDS were also younger and had higher micro-arousal index (MiI), as well as higher morning DBP, morning MAP and bedtime DBP than that in non-EDS group (P<0.05).Conclusions EDS in OSAHS patients is a special phenotype, which was characterized by younger age, higher DBP and more severe hypoxic load. This feature is mainly manifested in moderate and severe OSAHS patients. It is very important to identify the phenotype of EDS in patients with OSAHS, who may meet more benefits from effective treatment of OSAHS by correcting the intermittent nocturnal hypoxia and sleep fragmentation. 相似文献
