截瘫患者血红蛋白水平的10年回顾性分析

通过对97例截瘫住院患者连续10年的Hb测定结果进行回顾性分组研究,结果表明,无并发症组10年中Hb分布较一致,其均值与正常人比较无显著性差异(P>0.05),但12.3％的病例Hb水平低于正常人下限;当截瘫并发泌尿系感染、尿毒症或难治性褥疮等病症时,则导致Hb水平的降低。提出Hb测定结果,可做为在整体水平上观察截瘫患者的治疗及康复效果的指标。     

老年性腰椎间盘突出症的手术治疗

老年性腰椎间盘突出症是指60岁以上发病者．其发病率相对较低，在病理、临床表现、手术方式、围手术期处理等方面都有别于中、青年患者。我院1995年1月～2000年8月共手术治疗腰椎间盘突出症417例．其中老年性腰椎间盘突出症46例，占11．03％。现将资料完整并获得随访的41例报告如下。     

经氯硝柳胺浸泡后湖北钉螺脑神经节的超微结构变化

用透射电镜进一步观察了湖北钉离神经节的纤维鞘，神经节胞体区和神经纤维网的超微结构，并且在神经纤维网部位首先发现了两个典型突触，经氯硝柳胺浸泡后，钉螺脑神经节的超微结构发生改变，神经纤维，神经胶质细胞和神经细胞内的线粒体由变性至坏死，神经细胞内的的糖原有含量显著减少，神经纤维网也发生变化坏死，这为阐明氯硝柳胺的灭螺机制提供了有用的资料。     

老年全身麻醉患者血清ADP、S-100β蛋白及HIF-1α水平与术后认知功能障碍的相关性分析

目的探讨老年全身麻醉患者血清脂联素(ADP)、S-100β蛋白及缺氧诱导因子-1α(HIF-1α)水平与术后认知功能障碍(POCD)的相关性。方法选取南阳市中心医院2017年1月至2019年1月收治的159例接受手术治疗的老年患者,根据术后简易精神状态检查表(MMSE)评分分为POCD组(MMSE<27分,n=53)和非POCD组(MMSE≥27分,n=106),比较两组患者手术前后ADP、S-100β蛋白、HIF-1α水平变化,Pearson相关性分析MMSE评分与血清ADP、S-100β蛋白、HIF-1α水平的相关性,受试者操作特征(ROC)曲线分析血清ADP、S-100β蛋白、HIF-1α水平对老年全身麻醉POCD的预测价值。结果术后两组血清ADP水平和MMSE评分均明显降低,S-100β蛋白、HIF-1α水平明显提升,POCD组较非POCD组改变更明显(P<0.05);Pearson相关性分析显示,POCD组术后MMSE评分与血清ADP水平呈正相关,与S-100β蛋白、HIF-1α水平呈负相关(P<0.05);ROC曲线显示,ADP+S-100β蛋白+HIF-1α预测老年全身麻醉患者POCD的曲线下面积(AUC)、敏感度、特异度高于各指标单独预测。结论老年全身麻醉POCD患者血清ADP水平明显降低,S-100β蛋白和HIF-1α水平明显提升,与POCD发生密切相关,联合检测能提升POCD预测价值。     

武汉市20-26月龄幼儿睡眠状况与认知发育水平的相关性研究

目的:了解20-26月龄幼儿睡眠与认知发育状况,探讨幼儿睡眠状况与认知发育水平的相关性。方法:从武汉市健康宝贝出生队列中,筛选出1447例20-26月龄幼儿为研究对象,采用队列自编问卷和简易婴幼儿睡眠问卷收集幼儿的睡眠资料及其父母的一般人口学资料,采用Bayley婴幼儿发育量表对幼儿认知发育进行评估,采用线性回归模型分析各睡眠参数对幼儿认知发育的影响。结果:调查对象的平均智力发育指数和运动发育指数分别为(107.00±18.82)、(104.16±18.33)。夜晚睡眠时长12h以上(P<0.001)和夜间睡眠比(P=0.036)是幼儿智力发育的保护因素;入睡潜伏期是幼儿认知发育的危险因素(P<0.01);夜醒时长是幼儿运动发育的危险因素(P<0.001)。结论:幼儿睡眠状况与认知发育水平之间存在相关性,应保证幼儿足够的夜晚睡眠时长,重视入睡和夜醒时间较长的幼儿,以促进其认知发育。     

IMMUNOLOGICAL STUDIES ON THROMBOANGIITIS OBLITERANS

Using humoral immunity (gamma-globulin 18 cases, IgG, IgA, IgM each 30 cases, CH50, C3, C4 each 29 cases and CIC 31 cases), cellular immunity (E-RFC 68 cases, As 30 cases, SmIg, SmIgG each 18 cases, IMIT 30 cases) and immunopathological manifestations (light microscope, fluorescence microscope, transmitted electron microscope each 7 cases) as indices, we studied the immunological changes of "progressing", "remittent" and "stabilized" groups of patients with thromboangiitis obliterans (TAO) in different stages. Humoral immunity indicated that gamma-globulin, immune complex and IgG were all increased; cellular immunity indicated that the rate of T cells and suppressor cells was declined, while that of B cells was elevated. Immunopathologically, under light microscope all the layers of involved vessels were infiltrated with neutrophils, lymphocytes and monocytes; under fluorescence and electron microscope, immune complexes were found in the involved vessel walls. Our preliminary results suggest that TAO is an autoimmune disease relevant to antigen-antibody complex.     

TREATMENT OF HYALINEMEMBRANE DISEASE BYHUMAN AMNIOTIC FLUIDSURFACTANT

A case of hyaline membrane disease was treated successfully with pulmonary surfactant (PS) isolated from human amniotic fluid. Dosage was 150 mg phospholipid/kg. The exogenous surfactant was instilled into the airway via a tracheal cannula. Clinical symptoms, PO2 and FiO2 improved evidently 24 hours after administration. L/S ratio and phosphatidylglycerol recovered gradually in aspirates. Lung X-ray film manifested "white lung" before instillation of surfactant and showed a striking improvement 3 days after treatment. The duration of mechanical ventilation was 6 days. During the period of recovery complications of patent ductus arteriosus and bacterial pneumonia developed. However, the patient recovered completely and was discharged 32 days after admission.     

前药在单克隆抗体—抗癌药交联物导向治疗中的应用
