硫酸盐测定的固体铬酸钡与其悬浮液两种试剂的比较

铬酸钡比色法测定水中的可溶性硫酸盐，适用于测定硫酸盐含量在5200mg／L之间的清洁水样。由于本法中的一种试剂为铬酸钡悬浮液，使用前须摇匀，因此，每次用吸管加入的量误差很大，且铬酸钡悬浮液在放置中随着时间的延长，其稳定性也相应改变，空白值增高，本法将铬酸钡悬浮液用固体铬酸钡来代替取得良好的效果，完全可以满足日常监测工作的需要。     

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     

运动试验阳性轻微ST-T改变的ECG特点

对于心电图(ECG)有明显ST—T改变者，易引起医生和患者的注意而行进一步检查(如平板运动试验，超声心动图，心肌灌注扫描和冠状动脉造影等)。而轻微ST—T改变，常易被忽视而漏诊。2001年1月～2004年1月收集69例平板运动试验阳性而平静ECG轻微ST—T改变者进行回顾性分析，探讨其ECG变化特点，现报告如下。     

关于基层卫生人员培训工作的几点思考

目前，卫生行业一股基层卫生人员培训热潮正在兴起，这无疑是一件好事。但要想真正做好此项工作，充分发挥其在卫生事业发展中的基础性作用，尚需要准确把握基层卫生人员培训工作的性质及其在农村和社区卫生总体工作中的地位，科学规划和部署，构建起保障机制。     

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.

浅谈"两性"相关话题

孔子曰:"食、色,性也"。然而,自古对"性事"只做不说,羞于启齿,大多"无师自通",因此误处多多,实是难免。尤其现在各媒体上都占有相当篇幅,网络上更多,但良莠不齐,误人之处太多,实在是害人不浅。今我以资深的临床工作者、修炼中华昆仑瑜伽的探索者的身份对某些相关问题谈一点不同的看法。     

美国卫生管理教育
