老年人支气管异物延误诊治原因

目的探讨老年人支气管异物延误诊治的原因。方法对28例误诊的老年人支气管异物临床表现及误诊情况进行分析。结果老年人支气管异物病史诉说不清,临床缺乏特异性,医生重视不够,容易误诊为呼吸系统疾病。结论老年患者疑为支气管异物者,应详细询问病史,抗感染治疗无效时,应及时行纤维支气管镜检查。     

hs-CRP、TAS联合血脂检测在早老性痴呆症诊断中的应用研究

[目的]研究超敏C反应蛋白（hs-CRP）、总抗氧化状态（TAS）联合血脂检测在早老性痴呆症诊断中的应用价值：[方法]选择浦东新区精神卫生中心早老性痴呆专科门诊患者54例，作超敏C反应蛋白、总抗氧化状态与血脂检测。[结果]与对照组比较，实验组hs-CRP、TAS差异非常显著，t1=4．55，t2=2．79，P1〈0．001，P2〈0．01；血脂中甘油三酯、低密度脂蛋白胆固醇、载脂蛋白B、Lp（a）差异显著；t1=3.01，P1〈0．01，t2=2．21，P2〈0．05，t3=2．64，P3〈0．01，t4=1．91，P4〈0．05。[结论]超敏C反应蛋白、总抗氧化状态联合血脂（甘油三酯、低密度脂蛋白胆固醇、载脂蛋白B、Lp（a））检测对实验室诊断早老性痴呆症具有较好敏感性和特异性，临床应用前景乐观。     

Structural shielding design for a gamma ray stereotactic body radiotherapy system.

An OUR-QGD gamma ray stereotactic body radiotherapy system (body knife), made in China, is described. According to its structure and the principle of gamma radiation revolved on a focus, the energy distribution of scattered radiation in its treatment room is calculated. The structural shielding of the wall, roof, and door for a certain treatment room is calculated according to the local radiation protection law.     

Differential changes of retina dopamine binding sites and adenylyl cyclase responses following 6-hydroxydopamine treatment.

Both dopamine D1 and D2 receptors are present in rat retina. D1 receptors are positively coupled to adenylyl cyclase, while D2 receptors are negatively coupled. After intraocular administration of the neurotoxin 6-hydroxydopamine (6-OHDA) there is depletion of retinal dopamine by about 90%, as well as a decrease of the number of D1 and D2 receptor binding sites. Following the 6-OHDA lesion, there is an enhancement of the D1 receptor-stimulated accumulation of cyclic-AMP and a loss of D2 receptor-inhibited accumulation of cyclic-AMP. Our results suggest that some of the retinal D2 receptors are coupled to adenylyl cyclase and some are not.     

慢性疼痛与情绪障碍及其干预治疗效应

目的:分析慢性疼痛与情绪障碍之间的关系,探讨心理及药物治疗对慢性疼痛的干预作用。资料来源:应用计算机检索Medline1989-01/2004-05和Embase1989-01/2004-05有关慢性疼痛与情绪障碍关系的文献,检索词“Chronicache,emotionaldisorder,treament”,并限定文章语言种类为English。观察对象为疼痛持续时间超过6个月以上的患者。资料选择:选取有关慢性疼痛与情绪障碍关系及其治疗干预的文献,进行初审,删除陈旧及重复的文献,然后查找余下的文献全文。质量评价主要考察资料的真实性,调查设计是否严密,实施过程是否严格,统计学处理是否合理。资料提炼:共检索到20篇关于慢性疼痛与情绪障碍关系及其治疗干预的文献,11篇文献符合纳入标准。排除的9篇试验中,7篇系重复的同一研究,2篇是Meta分析。资料综合:11篇文献均包括观察组和对照组,其中观察组应用镇痛药合并心理治疗及抗抑郁药,对照组应用镇痛药但未合并心理治疗及抗抑郁药,对两组患者的疗效进行比较分析。结论:慢性疼痛与情绪障碍同时存在,应用镇痛药合并心理治疗及抗抑郁药可以显著缓解患者的疼痛,干预效果优于单纯应用镇痛药者。     

心血管疾病并发焦虑抑郁症状2050例心理干预治疗分析

目的:了解心血管疾病并发焦虑抑郁症状的情况并探讨心理干预等对焦虑抑郁症状的影响。方法:对住院的2050例心血管疾病并发焦虑抑郁症状的患者进行回顾性分析。结果:心血管疾病患者中并发有焦虑抑郁症状者占56%;其常表现为类似心绞痛、左心衰竭症状,可并发有心律失常;高血压病并发有焦虑抑郁患者对血压升高的耐受性差,动态血压检查以非勺型改变者居多;单纯使用心血管药物治疗效果欠佳,心理干预,焦虑抑郁症状严重者结合抗焦虑抑郁药物疗效显著。结论:心血管疾病患者常并发焦虑抑郁症状,心理干预治疗等可有效改善患者的症状。     

Treatment of myofascial trigger points in common shoulder disorders by physical therapy: A randomized controlled trial [ISRCTN75722066]

Background  

Shoulder disorders are a common health problem in western societies. Several treatment protocols have been developed for the clinical management of persons with shoulder pain. However available evidence does not support any protocol as being superior over others. Systematic reviews provide some evidence that certain physical therapy interventions (i.e. supervised exercises and mobilisation) are effective in particular shoulder disorders (i.e. rotator cuff disorders, mixed shoulder disorders and adhesive capsulitis), but there is an ongoing need for high quality trials of physical therapy interventions. Usually, physical therapy consists of active exercises intended to strengthen the shoulder muscles as stabilizers of the glenohumeral joint or perform mobilisations to improve restricted mobility of the glenohumeral or adjacent joints (shoulder girdle). It is generally accepted that a-traumatic shoulder problems are the result of impingement of the subacromial structures, such as the bursa or rotator cuff tendons. Myofascial trigger points (MTrPs) in shoulder muscles may also lead to a complex of symptoms that are often seen in patients diagnosed with subacromial impingement or rotator cuff tendinopathy. Little is known about the treatment of MTrPs in patients with shoulder disorders.
