职业性锰暴露工人健康状况调查分析

对１８２名职业性暴露于锰的电焊工人和１５４名无锰及其它重金属暴露史的对照工人进行健康状况调查，发现暴露组神经系统改变发生率为２６．９６，比数比为２．６２，并且锰暴露年数与神经系统改变呈剂量－反应关系。     

健康教育在左洛复治疗抑郁症中的效果观察

抑郁症是精神科的常见病，其发病病因尚不完全清楚，目前抑郁症的治疗以药物治疗为主，在临床应用较多的是选择性5-羟色胺摄取抑制剂(SS-RI)。本研究通过观察健康教育在左洛复治疗抑郁症中的效果，旨在探讨健康教育在抑郁症治疗康复中的可行性和有效性。

共同性斜视术后的回退问题

共同性斜视矫正术后,近期为双眼正位,但时间长后又能出现以下几种变化:①眼位回退到原斜视方向,②眼位向原斜视方向的相反方向移行;③保持双眼正位。如果我们能将引起眼位变化的因素加以分析,以指导我们手术,会提高斜视矫正手术成功率。现我们将我院的48例共同性斜视(共同性外斜30例,共同性内斜18例)矫正术3年后的情况报告如下:对象和方法一、一般资料;本组病例系1987年12月     

乌鲁木齐地区STD门诊患者支原体的检测与药敏分析

目的　了解近年本地区STD门诊患者支原体感染及耐药情况 ,为临床选择治疗提供参考依据。方法　对 173 7例STD门诊患者进行了支原体培养 ,并对阳性标本进行 9种抗生素药敏试验。采用支原体培养、鉴定、药敏一体化试剂盒进行检测。结果　 173 7例中支原体阳性 660例 ,感染率为 3 8.0 0 %。解脲脲原体 (UU )、人型支原体 (MH )及UU +MH混合感染的阳性率分别为 80 .0 0 % (5 2 8例 )、2 .2 7% (15例 )、17.73 % (117例 )。UU对 9种抗生素敏感性最高的是交沙霉毒 (97.4% ) ,其次是强力霉素、美满霉素 (均为 86.4% ) ;耐药性最高的为克林霉素 (74.2 % ) ,其次是氧氟沙星(3 3 .6% )、司巴沙星 (3 3 .0 % )。MH对 9种抗生素敏感性最高的是交沙霉毒、强力霉素、美满霉素 (均为 10 0 % ) ;耐药性最高的为阿奇霉素、左氧氟沙星 (均为 10 0 % )。结论　交沙霉素、强力霉素、美满霉素应作为本地区目前治疗泌尿生殖道支原体感染的首选抗生素。     

Rosiglitazone down-regulates lipopolysaccharide-induced expression of CD40 and intercellular adhesion molecule 1 in rat peritoneal mesothelial cells through a NF-κB dependent mechanism

Objective To investigate the effect and mechanism by which PPARγ ligand, rosiglitasone, regulates the expression of CD40 and intercellular adhesion molecule 1 (ICAM-1) in the rat peritoneal mesothelial cells (RPMCs) induced by lipopolysaccharide (LPS). Methods RPMCs were harvested from Sprague-Dawley rat peritoneal cavity and maintained under defined in vitro conditions. The cells were randomly divided into groups as follows: medium, LPS (5 mg/L), LPS (5 mg/L)+BAY11-7085(5 μmol/L, NF-κB inhibitor), rosiglitazone (10 μmol/L or 20 μmol/L, peroxisome proliferator-activated receptor γ activator), LPS (5 mg/L)+rosiglitazone (10 μmol/L)+GW9662 (3 μmol/L, peroxisome proliferator-aetivatcd receptor γ antagonist), and LPS (5 mg/L)+vehicle (DMSO 0.2 ml/L). The expressions of CD40 and ICAM-1 RNA in RPMCs were examined by RT-PCR after 3 hour treatment, and the protein expressions of CD40, ICAM-1, p-NF-κB p65 and p-IκBα were examined by Western blot or immunofluorescence after 24 hour treatment. Results Following treatment with LPS, both the expressions of CD40 and ICAM-1 protein in RPMCs were up-regulated significantly (P<0.05), and the phosphoralation of p65 was increased greatly (1.10±0.17 vs 0.55±0.06, P<0.05). BAY11-7085 (5 μmol/L) significantly decreased the protein expression of p-p65 (0.22±0.11 vs 1.10±0.17, P<0.01), CD40 (0.34±0.02 vs 0.50±0.06, P<0.05) and ICAM-1 (0.35±0.16 vs 0.74±0.03, P<0.05). Pretreated with rosiglitazone for 3 h then added with LPS for 1 h, the levels of p-p65, CD40 and ICAM-1 in RPMCs were significantly decreased compared with those of LPS group (0.77±0.08 vs 0.90±0.10, P相似文献   

左旋布比卡因复合芬太尼用于剖宫产术后硬膜外腔镇痛的观察

布比卡因（BUP）属长效酰胺类局麻药，已广用于临床，偶尔有引起心脏毒致循环衰竭甚至死亡的报道，与BUP的心脏毒较强，一旦心肌受抑制后难以逆转有关。左旋布比卡因（LBUP）是BUP的左旋镜像体纯提取物，资料表明其中枢神经毒及心脏毒比BUP低。本文将低浓度（0.25%）LBUP复合小剂量芬太尼（2μg/ml）由于手术后硬膜外腔镜痛（PECA），观察其镇痛效应，并与BUP比较，今报道如下。
