新型冠状病毒肺炎流行期间基于列线图预测隔离留观患者的焦虑抑郁情绪

<正>新型冠状病毒肺炎(COVID-19)因其传播速度快、传染性强及人群易感等特点,已被我国列入乙类传染病并按甲类传染病管理[1]。发热门诊隔离留观的患者具有发热等类新冠症状且面对环境的改变对心理可能带来负面影响。故本研究探讨COVID-19流行期间发热门诊隔离留观患者焦虑抑郁情绪及相关因素,以期尽早识别高危患者并进行心理干预治疗。     

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。     

脂联素与慢性阻塞性肺疾病相关性研究进展

脂联素是脂肪组织分泌的一种新的细胞因子,临床研究已证实其参与了能量代谢过程,与炎症标志物具有相关性,慢性阻塞性肺疾病为一慢性炎症过程,随着病情的进展,出现营养不良,因此考虑脂联素参与了慢性阻塞性肺疾病的病理生理过程.现将脂联素与慢性阻塞性肺疾病关系的研究进展综述如下.     

肿瘤坏死因子-α、白介素-8在阻塞性睡眠呼吸暂停低通气综合征患者及其合并冠心病发病中的作用

阻塞性睡眠呼吸暂停低通气综合征(OSAHS)是不稳定型心绞痛、心肌梗死等动脉粥样硬化性疾病独立危险因素.但其机制尚不清楚.本文观察OSAHS患者及其合并冠心病(CHD)患者血清肿瘤坏死因子(TNF)-α、白介素(IL)-8水平的变化,探讨细胞因子在OSAHS及其合并CHD发生发展中作用.     

阻塞性睡眠呼吸暂停低通气综合征及其相关高血压患者血清过氧化氢酶、谷胱甘肽过氧化物酶和丙二醛水平的变化

目的 探讨阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syndrome,OSAHS)及阻塞性睡眠呼吸暂停低通气综合征相关高血压(obstructive sleep apnea-hypopnea associated hypertension,OSAHAHT)患者血清过氧化氢酶(catalase,CAT)、谷胱甘肽过氧化物酶(glutathione peroxidase,GSH-PX)和丙二醛(malonaldehyde,MDA)水平的变化.方法 选择OSAHS患者24例,OSAHAHT患者21例;正常对照组23名,测定血清CAT、GSH-PX、MDA水平.并与睡眠呼吸监测指标进行相关分析.结果 与正常对照组比较,OSAHS组及OSAHAHT组血清CAT、GSH-PX活性均降低(P<0.01),MDA浓度均升高(P<0.01).OSAHS及OSAHAHT患者血清CAT、GSH-PX、MDA水平与反映睡眠呼吸暂停严重程度的指标有相关性(P<0.01).结论 OSAHS患者存在CAT、GSH-PX、MDA水平的变化,且与OSAHS的病情严重程度相关;氧化应激及氧化损伤在OSAHAHT患者中更明显.

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.
