Background and purposeTriggering receptors expressed on myeloid cells 1 and 2 (TREM-1 and TREM-2) are cell surface receptors important for modulation of microglia immune response. In this study, we evaluate serum levels of TREM-1 and TREM-2 as potential biomarkers in acute ischemic stroke (AIS).Material and methodsProspective cohort study of 50 patients with AIS admitted at our hospital. Serum TREM-1 and TREM-2 was evaluated within 24 h of the acute event and on the third and fifth days after the stroke. Neurological stroke severity and global disability were determined with the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) at the same three times and at the time of hospital discharge.ResultsTREM-1 and TREM-2 levels were elevated in stroke. TREM-1, but not TREM-2, exhibited correlations with NIHSS and mRS within 24 h (NIHSS and TREM-1: rS = 0.31, p = 0.029; mRS and TREM-1: rS = 0.32, p = 0.023). The serum level of TREM-1 within 24 h correlated with the neurological outcomes at hospital discharge (NIHSS and TREM-1: p = 0.021; mRS and TREM-1: p = 0.049). The serum concentrations of TREM-1 protein within 24 h after stroke was significantly higher in patients with poor outcome (mRS > 2) at hospital discharge (p = 0.021). After Exact Logistic Regression, large segmental stroke (O.R. = 4.14; 95CI = 1.07–16.09; p = 0.040) and initial sTREM levels (O.R. = 1.02; 95CI 1.00–1.04; p = 0.045) remained independent prognostic factors for AIS poor outcome (mRS > 2).ConclusionIn our study, TREM-1 and TREM-2 were significantly increased in AIS. Early elevation of TREM-1 correlated with stroke severity and it was an independent prognostic factor for stroke outcome. 相似文献

目的研究右美托咪定对心外科术后患者睡眠质量的影响。方法利用多导睡眠图对2018年1月至2018年12月长海医院心脏术后患者进行睡眠监测,选择最终符合条件的患者63例为研究对象,按随机数字表法分为试验组32例和对照组31例。试验组患者从晚上22:00试验开始时持续静脉注射右美托咪定,次日晨6:00停止注射,连续注射3晚。镇静目标为镇静程度评估表(richmond agitation-sedation scale,RASS)评分-1~2分,右美托咪定的负荷剂量为0.5μg/kg,时间不超过20 min,然后以0.2~0.7μg/(kg·h)持续静脉注射,期间不使用其他镇静剂。对照组患者晚间不注射右美托咪定以及其他镇静药物。此段时间用多导睡眠仪监测两组患者的睡眠。观察目标为两组患者睡眠总时间、睡眠效率、觉醒次数、睡眠各阶段时间。试验期间白天的睡眠由床旁护士记录患者睡眠次数。结果试验组与对照组比,有更少的觉醒次数[(3.1~3.61)次vs.(8.87~9.77)次,P<0.01],更高的睡眠效率(68%~71.29%vs.25.1%~28.87%,P<0.01),更长的睡眠第二阶段[(249.55~266.89)min vs.(59.12~71.59)min,P<0.01],差异有统计学意义。两组患者睡眠第一阶段比较,差异无统计学意义[(63.61~7.05)min vs.(56.37~63.33)min,P>0.05]。结论夜间持续输注右美托咪定显著提高了患者睡眠效率、减少睡眠觉醒次数、增加睡眠第二阶段的时间,在一定程度上改善了心外科术后患者的睡眠质量。 相似文献

目的通过对比三种消毒剂对ICU高频接触物体表面消毒后不同时间段的抑菌效果,从而为临床选择合适的物体表面消毒剂、规范ICU高频接触物体表面擦拭频率提供依据。方法分别采用一次性无纺布+改进型酸性氧化电位水、双链季铵盐消毒湿巾以及一次性无纺布+500mg/L含氯消毒液三种方法对ICU高频接触的物体表面进行擦拭,在擦拭前、擦拭后5min、擦拭后4h及擦拭后8h进行细菌采样,比较不同消毒剂在消毒后不同时刻的抑菌率、相关物体表面细菌合格率以及消毒成本。结果三种消毒剂消毒后即刻合格率均为100%,改进型酸性氧化电位水消毒后4h合格率和消毒后8h合格率高于其他两种消毒剂(均P<0.05);含氯消毒液灭菌率对涂有多重耐药菌MRSA的物体表面消毒后灭菌率最低,为99.28%,其余两组均为100%;改进型酸性氧化电位水单次使用成本最低,为0.81元。结论改进型酸性氧化电位水作为一种物体表面新型消毒剂,有效氯浓度低、消毒效果可靠,腐蚀性小,且消毒成本较低,可在医院感染重点科室推广使用。 相似文献
