高热惊厥脑干听觉诱发电位的分析

本文报道了30例高热惊厥患儿的脑干听觉诱发电位检测结果。结果提示,高热惊厥患儿脑干听觉诱发电位异常率较高,以Ⅰ—Ⅴ波峰间期延长为主,同时Ⅰ、Ⅲ、Ⅴ波耳间差值增大。文中讨论了这一结果与高热惊厥发病年龄特征的关系。

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。     

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.     

复方SZ滴眼液对实验性半乳糖白内障的防治作用

目的:探讨复方SZ滴眼液对实验性半乳糖白内障的防治作用。方法:以民间验方为基础、以水蛭(SZ)为主要成分,配制成SZ滴眼液;并在SZ滴眼液的基础上配制成富含锌和维生素C的复方SZ滴眼液。用SD大鼠复制D-半乳糖白内障模型。将实验分成3组:①生理盐水对照组;②SZ组;③复方SZ组。用FS-3V裂隙灯显微镜动态观察各组动物晶体混浊情况,并于实验第15d测定各组晶体的超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、谷胱甘肽(GSH)和可溶性蛋白(SP)的含量。观察并比较两种滴眼液对半乳糖白内障的防治作用。结果:复方SZ组和SZ组大鼠晶体混浊的速度均较对照组慢、程度也较轻;复方SZ组大鼠晶体混浊的速度较SZ组慢、程度也较SZ组轻。晶体抗氧化指标测定显示,复方SZ组和SZ组晶体的SOD、GSH-Px和GSH含量均明显高于对照组,而复方SZ组晶体的SOD和GSH-Px又较SZ组高。各组晶体SP含量无显著差异。结论:SZ滴眼液和复方SZ滴眼液均具有较好的延缓和减轻半乳糖白内障的作用,复方SZ滴眼液较SZ滴眼液的作用更明显。其机理可能与复方SZ滴眼液较SZ滴眼液更富含微量元素锌和维生素并具有更强的抗氧化能力有关。     

DICOM医学图像的存储与管理

随着数字化医学成像设备在医院的广泛使用,对医学图像及相关数据的存档管理以及在不同科室之间的数据共享的要求越来越迫切,这就需要建立PACS(图像存档和通讯系统),这方面国外已经发展了很多年,我国目前处于起步阶段.本文参照PACS系统的一个已经被国际认可的医学图像标准即医学成像和通讯标准DICOM(digital imaging and communication in medicine),研究了标准的各个部分,特别是兼容性、信息对象定义(IOD)、服务对象对类(SOP)、数据编码等部分,就具体实现PACS系统的一个重要方面即医学图像的存档和管理做了深入的探讨,在此基础上建立了医学图像数据库系统,为实现医学图像信息的网络共享打下了基础.
