MRI技术对高原人群颅脑脱髓鞘疾病回顾性研究

目的研究高原地区,脱髓鞘疾病与中老年人疾病等因素的关系。方法对我院所有接受过磁共振头部扫描的病人进行评估,确诊出40位脱髓鞘疾病患者,并对大脑7个部位的脱髓鞘疾病按严重性分4级打分,统计临床数据,最后运用统计学方法分析其相关性。结果在40例患者中,出现在大脑半球、放射冠、半卵圆中心和脑室前后角的脑白质损伤频率最多,分别占总量的50%、67.5%、77.5%和87.5%。脑白质损伤患者的平均年龄为47.1岁,这比世界其他地区都有明显的提前。男性患者将近是女性患者的3倍(29∶11)。年龄、慢性高原红细胞增多症、收缩压、脑梗塞与脑白质损伤正相关(P<0.05)。结论对于高海拔地区,有效控制高原心血管疾病的发生对于减少颅脑脱髓鞘疾病的发生具有重要意义。     

Analysis thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis in the lower extremities

Objective:To explore the effect of thrombolysis with anticoagulation treatment forearly stage of deep vein thrombosis of lower extremity.Methods:The clinical data of 10 patients at the early stage of deep vein thrombosis(DVT)in the lower extremuites treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively.Results:The thrombolytic effect was significant.After treatment,the deep veins were recanalized without regurgitation in 75.3% of the patients.The total effective rate was 100%.Only three patients had hemorrhagic complication,but none of the patients died.Conclusion:Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.     

铁代谢与肝癌预防

铁离子是人体中含量最大的金属元素，主要作为红细胞内的血红蛋白铁和肌肉中的肌红蛋白铁而从事分子氧的运输作用。它还存在于一切细胞之中，催化细胞内的氧化还原而形成多数的酶活性中心，并与细胞生长和凋亡等机制相关。铁离子如果在体内存在过剩，则其毒     

自控镇痛泵在妇产科手术病人中的应用与护理

为探讨"病人自控镇痛"方法在妇产科手术病人术后镇痛情况及其副反应的发生,应用相应护理措施,随机选择下腹部手术(全子宫切除、剖宫产)84例,年龄25岁～48岁(平均年龄35.5岁),均留置尿管,分为两组,观察其术后50 h内的病情变化,镇痛效果及其副反应.结果显示:研究组患者术后伤口疼痛轻,入睡情况明显优于对照组,不需要应用其他止痛及安眠镇痛药物,说明研究组镇痛效果满意.

An experimental study of spinal cord evoked potential.

The characteristics of spinal cord-evoked potentials were investigated by using an in vitro spinal cord preparation. The spinal cord isolated from adult rats was immersed in a bathing chamber filled with oxygenated artificial cerebrospinal fluid (aCSF). The spinal cord-evoked potentials elicited by the stimulation of the spinal cord were recorded by using bipolar platinum electrodes. The potentials recorded consisted of early and late negative components (N1, N2). The inhibitory effect of lowered temperature on the N1 potential was clearly demonstrated. The oxygen deprivation of aCSF showed the higher sensitivity of N2 potential to hypoxia than that of N1. It was also possible to analyze the effects of potassium and magnesium ion concentration and pH on the evoked potentials. These results showed that the pure effects of various physiological and chemical factors on the spinal cord-evoked potentials can be analyzed by this experimental model.
