Acupuncture treatment of 32 cases of lumbar intervertebral disc protrusion

Yaoyangguan (GV 3), Shiqizhui (Ex-B 8) and Yanglingquan (GB 34) were selected as main points and a three-part needle insertion technique was used to treat 32 cases of lumbar intervertebral disc protrusion. The curative rate was 96.9%. Deep puncture is the key to the treatment. Author: Chen Feng(1962-), male, junior consultant doctor Translator: Wang Si-you     

睡安口服液对小鼠镇静作用研究

目的:研究睡安口服液对小鼠的镇静作用。方法:通过抖笼换能器法,设置睡安口服液组与对照组,以活动曲线研究睡安口服液对Wistar种系小鼠的镇静作用。结果:对照组在给药前后有大波、中波出现,睡安口服液组可使小鼠活动明显减少,灌胃后20min大波完全消失,中波大部分消失,小波也减少。结论:说明该制剂镇静作用显著。     

兔感染性模型组织液中左氧氟沙星浓度HPLC测定

目的建立兔组织感染性模型组织液中左氧氟沙星药物浓度的高效液相色谱分析方法。方法以加替沙星为内标,室温下兔组织液样品15%高氯酸沉淀蛋白后,离心后取上清液进样测定。色谱柱为ZORBAXSB-C18(150mm×4.6mm,5μm)。流动相为0.05mol/L磷酸二氢钾∶乙腈∶三乙胺(82∶18∶0.3,V/V/V),pH4.5,流速1ml/min,荧光检测激发波长298nm,发射波长458nm。结果线性范围0.025～3.0μg/ml(r=0.9999)。低、中、高浓度的绝对回收率均大于76%,相对回收率在97%～104%,日内、日间RSD分别小于2%和4%。最低检测浓度为0.025μg/ml,最低检测限为2ng/ml,S/N>3。本方法准确可靠,操作简便,适用于体内生物样品测定。     

后路cage椎体间植骨融合术在下腰椎融合的应用

目的 探讨后路cage椎间植骨融合术治疗下腰椎疾病的应用价值。方法 运用后路cage椎间植骨融合术治疗腰椎间盘突出症10例，单纯腰椎滑脱症11例，腰椎管狭窄症3例，腰椎狭部不连2例。结果 术后经6。12个月随访，临床疗效优良率92．3％(优80．8％，良11．5％)，植骨融合率96％，短时神经功能障碍1例。结论 后路cage椎间植骨融合术是治疗下腰椎不稳或滑脱的有效方法，临床疗效满意。     

椎弓根内固定加椎体间植骨融合治疗腰椎间盘突出症伴腰椎不稳

目的 评价椎弓根内固定、椎体间植骨融合术在治疗腰椎间盘突出症伴腰椎不稳中的应用及其临床效果。方法 对75例腰椎间盘突出症伴腰椎不稳的患者行髓核摘除、椎弓根内固定加椎体间植骨融合术，病变节段分别为L3～4、L4～5和L5S1。结果 75例患者随访8～50个月，平均14．5个月。本组4例患者术后出现暂时性神经根牵拉症状，2例术后感染，椎体间植骨融合72例，不融合3例。所有病情均获不同程度缓解，无其他远期并发症出现。结论 椎弓根内固定加后路椎体间植骨融合治疗腰椎间盘突出症伴腰椎不稳，除解除椎间盘源性疼痛外，尚能提供椎间的牢固性，促进椎体间植骨融合，恢复椎体永久稳定性。     

术后椎间盘感染的MRI诊断价值探讨

目的探讨MRI对术后椎间盘感染的诊断价值。方法回顾分析18例经临床证实的术后椎间盘感染的MRI表现。结果18例患者中有23个椎间盘感染,其中16例发生于腰椎间盘。感染椎间盘不同程度的破坏、碎裂,呈长T1(15例)长T2(16例)信号,T2WI上髓核内正常裂隙状短T2信号消失(17例),椎间隙变窄(15例),相邻椎体终板及终板下骨质破坏(18例),椎旁软组织肿胀(9例)。3例行Gd-DTPA增强扫描,病变椎间盘及邻近椎体、椎旁软组织明显强化。结论MRI对诊断术后椎间盘感染具有较高的敏感性和特异性,应作为首选的影像学检查方法。     

腰椎间盘退变动物模型的建立及MRI观察

目的通过手术方法建立一种新的动物模型并在磁共振(MRI)下观察。方法随机选取32只SD大鼠,分为实验组和对照组,每组16只。采用手术方法以L3为中心切除棘突、关节突、棘上棘间韧带,切断双侧竖棘肌。对照组仅切开皮肤后即缝合。术后分别于1、2、3个月行MRI检查。结果对照组T2信号仅有轻度改变,而实验组T2信号明显降低。结论本动物模型成功地建立可为腰椎间盘退变的研究提供较为满意的实验平台。     

The Herniated Thoracic Disc: A Review of Literature

Abstract

This literature review discusses the epidemiology and etiology of thoracic disc lesions and describes signs and symptoms, diagnostic procedures, differential diagnosis, and treatment. Data presented in case series reports published between 1985-2001 is summarized: Thoracic disc herniations are more common than previously thought. They may cause mild, moderate, severe or confusing symptoms or be asymptomatic; 49% of cases were in men and 51% in women. Trauma was a precipitating factor in 31%; multiple herniations were reported in 9%. In symptomatic cases, 57% of patients presented with radicular pain, 48% with back pain, 63% with weakness, 60% with sensory complaints, 25% with bowel or bladder symptoms, and 59% with hyperreflexia. Typical presentations of upper, middle, and lower thoracic disc are summarized. Diagnosis is made by correlating clinical signs and symptoms with the results of diagnostic imaging. Surgery is recommended for patients with progressive neurological dysfunction. Research on the efficacy of conservative treatment is lacking in the literature.
