超声诊断室间隔膜部瘤的初步价值

目的：观察室间膈膜部瘤的形成对室间膈自然闭合的价值。方法：采用HP－77020AC型彩色多普勒超声诊断显像仪对患有室间膈缺损（VSD）的8例室间膈膜部瘤（VAS）患进行定期跟踪随访，2－7年后，除2例室间膈膜部瘤尚有小开口外，其余6例均自然闭合。结果：彩色多普勒超声对室间膈膜部瘤的诊断简便可靠。结论：室间膈膜部瘤的形成大大提高了VSD的自然闭合可能性。     

深入开展临床血液学的实验室检查

临床血液病的诊断须以临床资料(病史、症状、体征)为基础，再借助于辅助检查(检验、影像、病理)的结果，通过医师的积极思维，最终得出可靠的诊断。因此，实验室检查是血液病诊断中不可缺少的手段。这种检查一般可分为常用实验和现代实验两部分，根据临床需求将两部分实验紧密结合应用，才能对血液病的诊断、鉴别诊断、疗效观察和预后判断做出正确的结论。     

当归多糖对放射损伤小鼠红细胞免疫功能和造血功能的保护作用

目的 进一步了解当归移糖的药用价值。方法 将小鼠发为正常对照组，照射对照组，当归多糖治疗组，检测三组的红细胞C3b受体花环率和外周血象。结果 照射对照组红细胞C3b受体花环率和外周血白细胞、血小板明显低于正常组，而当时多糖治疗组的红细胞C3b受体花环率和外周血白细胞、血小板显著高于照射对照组，有统计学意义（P＜0．01）。结论 当归多糖对放射小鼠红细胞免疫功能和造血功能具有保护作用。     

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.     

骨质疏松大鼠胰岛素样生长因子—1血清水平和转化生长因子β1骨表达的实验研究

目的：观察骨质疏松大鼠不同时期骨密度（BMD）、血清胰岛素样生长因子－1（IGF－1）的浓度以及骨组织中转化生长因子β（TGF-β1）的表达，进一步探讨绝缘后骨质疏松与细胞因子的相关性。方法：将60只10－12月龄的SD大鼠随机分成实验组和对照组，用摘除双侧卵巢的方法制备实验大鼠骨质疏松模型，实验组行摘除双侧卵巢术，对照组行假手术，仅切除卵巢周围的脂肪组织，应用HOLOGIC第4代双能X线4500W骨密度仪测量去卵巢不同时期（术后8，12，16周）大鼠全身骨密度和腰椎感兴趣区域（L1－L4）骨密度，并采用ELISA法和免疫组伦的方法，检测去卵巢大鼠不同时期血清IGF－1水平和骨组织中TGF－β1表达。结果：全身骨密度、去卵巢组大鼠在术后第8周和第12周，全身骨密度与对照组（假手术组）无明显差异（P＞0．05），在术后第16周，开始出现全身骨密度降低,与对照组相比，有显著差异（P＜0．01）。腰椎（L1－L4）骨密度；从术后第8周－第16周，去卵巢组血清IGF－1浓度值均低于对照组（P＜0．05）。骨组织TGF－1浓度：从术后第8周－第16周，去卵巢组血清IGF－1浓度值均低于对照组（P＜0．05）。骨组织TGF－β1表达：去卵巢组在术后第8周骨组织中软骨细胞、成骨细胞、骨基质TGF-β的表达程度与对照级有明显不同（见图1，2）。结论：绝经后骨质疏松的发病与IGF－1、TGF－β1的关系密切。     

输尿管结石继发炎性息肉66例分析

目的：探讨输尿管结石继发息肉发病机制，预防漏诊漏治。方法：1991年1月至2001年12月，采用开放手术和输尿管镜手术治疗输尿管结石继发息肉66例。结果：66例经病理证实为炎性息肉，64例痊愈，开放手术组有2例出院后反复出现尿路感染，其中1例致输尿管狭窄再手术，40例获随访，结石无复发，肾功能改善或恢复。结论：输尿管结石继发息肉术前确诊十分困难，如果漏治，必将导致结石复发；在诊治输尿管结石继发息肉中，输尿管镜手术较开放式有其优势，但技术要求较高。
