慢性心衰患者电话干预的随机试验：DIAL试验

目的:明确集中的电话干预能否降低慢性心衰门诊患者死亡或因心衰加重而住院的发生率。设计:多中心、随机对照试验。地点:阿根廷的51个中心(包括公立、私立的医院及流动设施)。参与者:1518例患有稳定的慢性心衰且已接受最佳药物治疗方案治疗的门诊患者,由心脏科主治医师分层后随机分为电话干预组和常规治疗组。干预:在常规治疗的基础上,由一个中心通过护士频繁的电话随访对患者进行教育、辅导和监督。主要观察指标:全因死亡或由于心衰加重而住院。结果:99.5%的患者完成了全部随访。常规治疗组758例患者中由于心衰加重而住院或死亡的比例(235…     

职业性萘暴露工人的健康监护结果评价

目的：讨论萘对人体的慢性毒效应和亚临床客观检测指标。方法：对河南省萘暴露工人（环境接触萘浓度平均为８．２５～２６．４３ｍｇ／ｍ３）进行了健康监护和医学动态观察。结果：发现长期萘暴露工人的白细胞、血小板减少及眼晶体混浊检出率显著高于对照组（Ｐ＜０．００１）；血清ＳＯＤ同功酶、ＧＳＨ－ＰＸ活性显著低于对照组，而ＬＰＯ水平、神经元特异性烯醇化酶（ＮＳＥ）活性水平以及外周血染色体畸变和微核阳性检出率均显著高于对照组（Ｐ＜０．００１）。神经行为功能检查结果，主要为消极情绪增加，记忆力下降等。事件相关电位Ｐ３００峰潜伏期比对照组显著延长，与对照组差异显著（Ｐ＜０．０５）。结论：慢性低浓度萘暴露对工人主要损害部位（靶器官）有皮肤，眼、血液和神经组织等。ＮＣＴＢ、ＮＳＥ、Ｐ３００三项可作为早期神经受损的客观指标。     

An analysis of astrocytic cell lines with different abilities to promote axon growth

The adult mammalian central nervous system (CNS) lacks the capacity to support axonal regeneration. There is increasing evidence to suggest that astrocytes, the major glial population in the CNS, may possess both axon-growth promoting and axon-growth inhibitory properties and the latter may contribute to the poor regenerative capacity of the CNS. In order to examine the molecular differences between axon-growth permissive and axon-growth inhibitory astrocytes, a panel of astrocyte cell lines exhibiting a range of axon-growth promoting properties was generated and analysed. No clear correlation was found between the axon-growth promoting properties of these astrocyte cell lines with: (i) the expression of known neurite-outgrowth promoting molecules such as laminin, fibronectin andN-cadherin; (ii) the expression of known inhibitory molecules such tenascin and chondroitin sulphate proteoglycan; (iii) plasminogen activator and plasminogen activator inhibitor activity; and (iv) growth cone collapsing activity. EM studies on aggregates formed from astrocyte cell lines, however, revealed the presence of an abundance of extracellular matrix material associated with the more inhibitory astrocyte cell lines. When matrix deposited by astrocyte cell lines was assessed for axon-growth promoting activity, matrix from permissive lines was found to be a good substrate, whereas matrix from the inhibitory astrocyte lines was a poor substrate for neuritic growth. Our findings, taken together, suggest that the functional differences between the permissive and the inhibitory astrocyte cell lines reside largely with the ECM.

同种原位肝移植围手术期的处理

目的 总结我院自1999年8月以来,开展的3例同种异体原位肝移植（Orthotopic livertransplantation,OLT）围手术期的处理过程及经验体会。方法　2例原位肝移植、1例肝-肾联合移植术。均在术前12h口服环孢霉素A（CsA）和骁悉（MAP）,术中用甲基强的松龙（MP）1000 mg静脉冲击防止排斥,术后MP+CsA+MAP三联用药。结果 ①文中3例病人手术均获成功,其中2例原位肝移植病人存活至今,生活质量良好。肝肾联合移植病人于术后第76d死于严重混合感染。②移植肝的功能维护是肝移植术后处理的重点,其中包括急性排斥反应的诊断和处理,以及其它可能引起肝移植肝功能损害、衰竭等问题的处理。③全身非移植器官的功能恢复:包括呼吸系统、感染、出血、胸水、腹水等并发症的处理过程。结论 肝移植围手术期的处理是肝移植成功与否的关键,其中包括肝移植的排斥反应及各系统的功能支持与维护。

Electrophysiologic evaluation of Emery-Dreifuss muscular dystrophy. A single fiber and quantitative EMG study

A 16-year-old boy, the only affected member of the family, noticed early onset contracture of the elbows, and developed slowly progressive humeroperoneal weakness and atrophy, and bilateral equinus. The severe restriction of the forward flexion of the neck and thoracolumbar spine, resembled a rigid spine syndrome. An electrocardiogram showed atrioventricular conduction abnormalities. Muscle biopsy was consistent with mild myopathy. The overall conventional findings of a detailed electromyographic study in the limbs and erector trunci muscles, as well as the results of conduction velocity, automatic analysis of the voluntary pattern and single fiber electromyography studies were consistent with myopathy, although some atypical findings were found. The controversy about neurogenic and myopathic features in Emery-Dreifuss disease is discussed. The unspecific value of the flexion limitation of the spine, and the uncertain nosological position of the rigid spine syndrome are also commented.
