The clinical analysis of three methods in the treatment of intracranial bacterial infection

Objective To analyze the effect of three therapeutic methods to find an optimal approach to the treatment of intracranial bacterial infection by retrospectively reviewing 33 intracranial bacterial infection patients who were admitted from 1995 to 2008 in oar hospital. Methods The treatments by intermittent lumbar puncture,continuous lumbar subarachnoid space drainage, and embedment of Ommaya cyst for continuous drainage from the ventricles were performed in 15 cases, 12 cases, and 6 cases respectively along with intravenous application of full dose of antibiotics. Results Nineteen cases were cured and the best prognosis was from the group of Ommaya cyst embedment and continuous drainage from the ventricles. Conclusion Management goals are prompt recognition of the central nervous system (CNS) infection, rapid identification of causative organisms and initiation of treatment with the optimal management methods for complications. Embedment of Ommaya cyst for continuous drainage from the ventricle is a safe and effective treatment for intracranial bacterial infection.     

外固定支架治疗股骨转子骨折82例报告

我院1993～1996年用单侧多功能外固定支架治疗82例股骨转子骨折，骨折愈合及去除支架的时间为2～5个月，平均3．5个月，其中8例（占10％）有轻度馊内翻畸形。此法治疗可早期负重，给骨折部位以生理应力刺激，进克长期卧床的共发症，且闭会复位，方法简便，易于接受，值得推广。     

应用单侧多功能外固定支架治疗四肢骨折

我院自１９９３年以来应用单侧多功能外固定支架治疗各种类型的四肢骨折共８６例，随访６～１８个月，均获得满意疗效。该支架体积小，结构简便，调整度大，可提供良好固定而无需手术，对粉碎型及合并感染者尤为适应。后期可改为弹性固定。允许早期活动，无需二次手术取内固定物。     

X线引导下的骨骼活检

作者用20~#～23~#穿刺针改制的针芯,尖端呈三棱形、针管为“Z”型切口的骨穿刺针,在X线引导下对200例各种骨疾病进行了穿刺活检。本组未出现并发症,该穿刺针适用于除努椎病变外的各种骨疾病检查。X线引导下的骨骼活检是一种安全、有效的诊断和鉴别诊断方法。     

促渗剂对盐酸小檗碱体外经皮渗透的影响

目的　研究几种促渗剂对盐酸小檗碱体外经皮渗透的影响。方法　在离体透皮实验装置上 ,以 30 % (体积分数 )乙醇作为接收液 ,观察盐酸小檗碱经大鼠腹部皮肤的渗透性 ,按规定时间取样 ,用高效液相色谱法 (HPLC)测定盐酸小檗碱的经皮渗透量。结果　几种促渗剂对盐酸小檗碱均有促渗透作用 ,不同透皮促渗剂促渗作用的大小顺序为 :氮酮 <丙二醇 <油酸 <冰片 <冰片 +丙二醇 <氮酮 +丙二醇 <油酸 +丙二醇。结论　氮酮、丙二醇、油酸、冰片、冰片 +丙二醇、油酸 +丙二醇、氮酮 +丙二醇均可作为促渗剂用于盐酸小檗碱的经皮吸收制剂。     

应对行车“爆胎”危象的防范措施

防范和预防行车“爆胎”而引发的交通灾害，要把工作做在前面，未雨绸缪。推广应用“爆胎应急安全技术”，是一项有重大价值的交通安全民心工程，政府应在政策上、组织上和经济上给予支持，特别是应高度关注营运客车、危险品运输车辆的运输安全问题，因为它们极易引发群死群伤恶性事故。     

Teleoperated Puncture Robot System:Preliminary Design and Workspace Analysis

Radiofrequency ablation (RFA) guided by X-ray images aims to relieve herniated disc pain with mini-mal invasiveness and fast recovery.It requires an accurate and fast positioning of the puncture needle.We propose a teleoperated robotic system for percutaneous puncture to support RFA.We report the kinematics modelling and workspace analysis of the proposed system,which comprises preliminary and accurate positioning mechanisms.Preliminary positioning mechanism automatically drives the needle to the puncture area,and accurate positioning is then achieved by teleoperation under the guidance of X-ray images.We calculate the teleoperation workspace of the robot system using a spatial search algorithm and quantitatively analyze the optimal structural parameters aiming to maximize the workspace.The workspace of the proposed robot system complies with clinical require-ments to support RFA.     

腰椎穿刺术治疗原发性脑干出血患者破入脑室18例临床分析

探讨腰椎穿刺术对脑干出血破入脑室患者的治疗作用。方法　对 1 8例脑干出血破入脑室患者 ,除给予常见内科治疗外 ,并配合腰椎穿刺治疗。结果　经腰椎穿刺术治疗 ,痊愈 5例 ,好转 7例 ,死亡 6例 ,死亡率 33.3% ;神经功能缺损评分明显降低。结论　用腰椎穿刺术治疗脑干出血破入脑室 ,可以明显降低死亡率 ,缓解临床症状 ,具有较好的疗效     

鞘内给氧与高压氧对颅脑损伤患者神经功能恢复的对比研究

目的　通过鞘内给氧与高压氧对颅脑损伤患者神经功能恢复的情况对比研究 ,探讨鞘内给氧对颅脑损伤患者神经功能障碍的治疗作用及其机制。方法　选择 15 0例颅脑损伤患者 ,随机分为鞘内给氧组、高压氧治疗组和鞘内注入过滤空气组 ,分别施行鞘内注入氧气、高压氧治疗及鞘内注入过滤空气 ,观察患者神经功能的改变 ,并检测脑脊液中超氧化物歧化酶 (SOD)、丙二醛 (MDA)和一氧化氮 (NO)水平的变化。结果　鞘内给氧组患者神经功能得到明显改善 ,且脑脊液中SOD、NO水平增高和MDA水平降低均较高压氧组明显。结论　鞘内给氧可以促进颅脑损伤患者神经功能障碍的改善 ,优于高压氧 ,且简便易行
