下肢手术患者罗哌卡因硬膜外麻醉运动阻滞的半数有效浓度

硬膜外麻醉产生镇痛以及运动阻滞的效果,取决于局麻药的容量,浓度以及剂量,手术要求阻滞区域镇痛完善,肌肉松弛,而术后镇痛则要求在完善的镇痛基础上尽量保留阻滞区域的运动功能,即通常所说的感觉-运动分离阻滞。由于罗哌卡因在较低浓度范围内就能产生良好的感觉-运动分

Effect comparison between sacral blocking and massage combined with traction on protrusion of lumbar intervertebral disc

Background:Epidural injection is an important method in treatment of protrusion of lumbar intervertebral disc.Especially in the recent decade sacral injection is adopted more and more often.Objective:To compare the clinical effects of sacral blocking and massage combined with traction.Unit:Yinhe Hospital of Beijing.Subjects:290 outpatients with grade Ⅱ of ASAI were selected from May,1994 to July,2000.Patients were randomly divided into observation group(n=145)and control group(n=145).Sacral blocking was adopted in observation group and 80 males and 65 females aged 20-78(mean:46.4)years old were included with disease course 3 days to 30 years.Massage combined with treaction was adopted in control group and 74 males and 71 females aged 22-74(mean:44.9)years oled were inmcluded with disease course 2 days to 10 years.Interention:Sacral blocking:Operation was according to sacral blocking and druge(dexamethasone injection,2 mg;0.75% bupivavaine hydrochloride,5 ml;saline,50ml) were injected slowly after success of puncture.Patient rested for 0.5h after injection and left treatment room if no adverse effects occurred.Massage combined with traction:Massage was adopted after traction to every patients.(1)Massage:Patient was seated at square stool and lower limbs separated naturally with same width of shoulders.Doctors sit behind patient.First,thubs of both hands were pressed on projecting part near spinous process(pressing points were selected according to different projecting part).Flexing and extending forward and backward were taken at the same time and extent was ddecided addording to patients‘ maximal endurable degree,5-10 timmes.Upper part of body was turned 45 degrees to left and right.Massage was still taken to affected part,3-t times.(2)Traction:Pelvis was extracted with general physical therapy and massage table.Supine position,chest and treaction bandage were fixed,tractiron wheel was turned slowly until patient felt comfortable with maximal endurance as limit(traction force,20-40kg),After extracting for 5 minutes,massagee switch was turned on to take rolling massage to bck and both lower libmbs.Traction force was increased every5 minutes and limit was still according to patient‘s maximal endurance,30 minutes for every time,once a day and ten times as a therapeutic course.Cohclusion:Effect of sacral blocking on protrusion of lumbar intervertebral disc was positive and fewer therapeutic time were needed.Massage combined with traction was also effective,safe and no adverse effects wer observed,but more therapeutic times were neeeded and inconveinient.     

糖尿病的运动疗法及饮食护理

糖尿病是因体内胰岛素绝对或相对缺乏而引起的全身代谢性疾病，运动疗法及饮食疗法在对糖尿病的治疗中占据重要的位置，正确掌握它们是广大糖尿病患者的迫切要求，通过我们近年来对糖尿病患者的观察中，所得的经验体会如下。

新生儿脐肠瘘一例

患儿男，于2003年4月4日自然分娩。其母以往健康，孕期顺利无任何不适，未用任何药物，出生时Apgar评分1min 10分，出生体重3400g。外观无畸形，心肺正常，腹软，肝肋下1．5cm，脾肋下1cm。四肢运动自如，各种反射均正常。生后半小时内开奶，母乳喂养，按需哺乳，吃奶好，大小便通畅。出生第4天发现脐部有胎便样物溢出，拟诊为卵黄管发育异常；第5天脐蒂自然脱落，每天均有约3ml胎便样物从脐部溢出；第10天转小儿外科手术。术后诊断：脐肠瘘。术后第9天治愈出院。随访半年，婴儿发育营养均正常。     

运动与血管假血友病因子

血管内皮细胞分泌的血管性假血友病因子(von Willebrand factor，vWF)部分沉积于内皮下层，与GPIb结合位点结合介导血小板黏附；部分进入血浆，血浆vWF含量的测定常作为血管内皮损伤的一项指标。文章探讨了急性运动和运动锻炼与vWF之间的关系，并就血管内皮细胞内分泌功能的影响。     

不同负荷运动训练对大鼠红细胞膜特性的影响

本文采用实验研究方法,通过对大鼠运动后红细胞数量,Hb浓度及体重等一般情况的检测,拟对其施加不同负荷的训练,观察训练后大鼠红细胞膜流动性及红细胞膜脂质成分的变化,进一步讨论运动后红细胞功能及机体机能所发生的变化。实验结果表明,小负荷的运动训练通过改善RBCM脂质组成,增加p/c比值、增强其抗氧化能力等增加RBCM流动性,使红细胞的变形能力增加,有利于其运氧功能的发挥。大负荷训练后RBCM流动性下降,提示不同负荷的运动训练会引起机体产生不同的变化,进而导致机体运动水平上的差异,整体携氧能力下降。     

肌肉骨骼生物力学的现状与展望

目前,肌肉骨骼生物力学不仅要适应所有应用力学先进的理论和技术,还要不断丰富和挑战力学已存在的分支和新领域.这一专业在运动和娱乐器材的设计、运动员的训练、环境和工作条件的改善（生物工程学领域）、工作和交通的安全性等方面发挥了较大的作用.此外,它还主要服务于医学领域的以下几个方面：骨科、康复医学、运动医学、整形和颌面外科、牙科等.毫无疑问,现在是吸收和补充那些受过良好培训的应用力学专家和工程师到这一领域来的大好时机,让他们在生物力学领域拓展研究范围,建立一个有挑战性的、有回报的事业.我们需要更加努力地工作,更富于创造性,更善于自我批评,在生物工程领域尽我们的责任,重树我们的形象.
