Severe lumbar spinal stenosis combined with Guillain-Barré syndrome: A case report

BACKGROUNDGuillain-Barré syndrome (GBS) is a rare disorder that typically presents with ascending weakness, pain, paraesthesias, and numbness, which mimic the findings in lumbar spinal stenosis. Here, we report a case of severe lumbar spinal stenosis combined with GBS.CASE SUMMARYA 70-year-old man with a history of lumbar spinal stenosis presented to our emergency department with severe lower back pain and lower extremity numbness. Magnetic resonance imaging confirmed the diagnosis of severe lumbar spinal stenosis. However, his symptoms did not improve postoperatively and he developed dysphagia and upper extremity numbness. An electromyogram was performed. Based on his symptoms, physical examination, and electromyogram, he was diagnosed with GBS. After 5 d of intravenous immunoglobulin (0.4 g/kg/d for 5 d) therapy, he gained 4/5 of strength in his upper and lower extremities and denied paraesthesias. He had regained 5/5 of strength in his extremities when he was discharged and had no symptoms during follow-up.CONCLUSIONGBS should be considered in the differential diagnosis of spinal disorder, even though magnetic resonance imaging shows severe lumbar spinal stenosis. This case highlights the importance of a careful diagnosis when a patient has a history of a disease and comes to the hospital with the same or similar symptoms.     

放射性心脏损伤动物模型相关实验研究进展

当利用放射线对胸部恶性肿瘤进行治疗时，位于纵隔的心脏会不可幸免受到照射，从而诱发放射性心脏损伤（radiation-induced heart disease, RIHD）。随着手术以及放化疗技术的提升，肿瘤患者生存时间得到延长，使得RIHD这一放疗远期并发症被越来越多的报道。因此，学者们对于RIHD的研究逐渐升温。目前国内外学者关于该疾病尚未形成统一的认识，临床上缺乏有效阻止其发生的方法。动物模型研究可为临床该疾病治疗及预防提供可靠证据，为此本文回顾分析近年来放射性心脏损伤动物模型实验研究情况，旨在为后续实验开展及临床应用提供参考。     

渐进性活动训练预防膀胱全切、尿流改道术后患者小肠梗阻的对照研究

目的研究渐进性活动训练对膀胱全切、尿流改道术后患者肠功能恢复的影响.方法2003年1月～2005年8月,将138例行膀胱全切、尿流改道术的患者随机分为2组,训练组在常规护理方法的基础上,同时实施渐进性活动训练,对照组采取常规护理方法.结果2组患者小肠梗阻的发生比较,差异有显著意义(P＜0.01).结论渐进性活动训练可降低膀胱全切、尿流改道术后患者小肠梗阻的发生.     

环境护理研究的历史与现状及存在的问题

对环境护理研究的历史、现状和存在的问题进行综述。认为现代环境护理研究的现状和环境护理的内容缺乏系统性，环境护理理论和临床实际操作联系不紧密或相互脱节是其主要问题。提出科技工作者应进行加强现代环境护理研究，尤其是服务工作者需创建以病人为中心，满足患者需求的安全、舒适和谐的整体化护理环境，以使患者早日恢复健康。     

928株革兰阴性杆菌耐药性监测

目的：了解青岛地区临床分离的重要革兰阴性杆菌的耐药情况以指导合理用药。方法：2001年青岛3家医院临床分离的5种革兰阴性杆菌用Kirby-Bauer法进行药敏试验。结果：5种病原菌均占3家医院革兰阴性杆菌分离率的前5位，大肠埃希菌对氟喹诺酮类药物的耐药率达60％－87％，细菌对亚胺培南均呈高度敏感，但铜绿假单胞菌耐亚胺培南株占25．8％，头孢他啶的抗菌活性是三代头孢菌素中最高的；复方酶抑制剂表现出良好的抗菌活性。结论：细菌耐药问题仍是目前临床的严重问题，地域性的耐药性监测是必要的。

Agilent 2100 Bioanalyzer在基因差异表达研究中的应用

目的观察Agilent 2100 Bioanalyzer 芯片分析系统(以下简称Bioanalyzer)在基因差异表达研究中的应用。方法应用限制性显示技术分别从正常和热休克处理后的酿酒酵母细胞中分离出cDNA片段,然后再用Bioanalyzer和传统的琼脂糖凝胶电泳技术对RD-PCR产物进行检测分析。结果Bioanalyzer能更快速、敏感地分离和显示差异表达的基因片段,并且通过对差异片段进行定量比较,发现了数个表达有明显差异的基因片段。结论Bioanalyzer在基因差异表达研究中具有重要的应用价值。     

Noradrenergic activation of immediate early genes in rat cerebral cortex.

Previous studies have shown that stimulation of adrenergic receptors in the brain increases the expression of the immediate early gene (IEG), c-fos, in vivo (Mol. Brain Res., 6(1989) 39-45). The present study was undertaken to determine whether this also holds for other IEGs which have been shown to be activated in brain cell culture by adrenergic agonists. Both yohimbine injection and stressful stimulation, two treatments causing brain norepinephrine (NE) release, were found to cause a parallel, transient activation of at least 5 IEGs (c-fos, nur77, tis-7, zif-268 and tis-21) in the rat cortex. Genes that are not immediate early (beta-actin, NGF and HSP70) were found not to be affected in the interval used (6 h). The responses were mediated predominantly by beta-adrenoceptors with some contribution from alpha 1 receptors. The parallel activation of multiple genes by noradrenergic receptors may enable the coding of different biochemical responses to the activation of different receptors.     

Plasma proteins in a standardised skin mini-erosion (II): effects of extraction pressure

Background  

A standardised suction technique has been used to sample plasma proteins in dermal interstitial fluid (IF) serially for 5 to 6 days from a suction-induced skin mini-erosion. Increased protein concentrations ascribed to inflammation have been shown from day 1 onward. In this study, we assessed the effect of two different extraction pressures on IF sample composition.
