Surgical strategy of one stage surgery of anterior release combined with posterior correction in treatment of severe scoliosis

Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon. Methods :Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thorac icplasty. Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80. 6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average. Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.     

螺旋CT及重建技术对肺隔离症的诊断价值

肺隔离症是一种少见的先天性肺发育异常，其主要特点是病变组织由体动脉供血且与正常肺组织相分离。诊断本病最重要的是显示肺内病灶有来自体循环的异常供血动脉，以及病变与肺实质之间的互相关系。近年来随着螺旋CT及重建技术的发展，尤其是螺旋CT三维重建血管成像（3DSCTA）能准确、多方位地提供血管走行情况，对肺隔离症的诊断正确率很高。     

3种钾通道在哮喘豚鼠气道高反应中的作用

目的：探讨钙激活钾通道（KCa）、延迟整流型钾通道（Kdr）和ATP敏感型钾通道（KATP）在哮喘豚鼠气道高反应中的作用。 方法： 采用离体气管环张力实验，观察加入特异性钾通道阻断剂后，与不加阻断剂相比气管环对组胺反应的量效曲线的差异。 结果： （１）加入KCa阻断剂TEA后，对照组气管环对组胺的反应变化不显著，而哮喘组气管环对10-4mol/L、10-3mol/L组胺的收缩反应均显著低于不加TEA的气管环(P<0.01)，量效曲线明显下移；（2）加入Kdr阻断剂4-AP后，对照组气管环对10-3mol/L组胺的最大收缩反应明显下降(P<0.05)，组胺的量效曲线下移，哮喘组气管环对10-4mol/L、10-3mol/L组胺的收缩反应均低于不加4-AP的气管环(P<0.01)，且下降程度较对照组大（P<0.05），量效曲线明显下移；（3）加入KATP阻断剂glibenclamide后，对照组和哮喘组气管环对组胺的量效曲线与不加glibenclamide的气管环相比变化均无明显差异。 结论： 在豚鼠哮喘模型中，KCa和Kdr活性的降低在气道高反应的发生中起介导作用，KATP作用不明显。     

老年痴呆住院患者常见护理问题干预

老年痴呆在我国的发病率逐年增长，已经成为一个导致老年人死亡的重要的老年病，一个不容忽视的社会问题。老年痴呆目前尚无根治的药物和途径。笔者通过一年多的针对老年痴呆患者的护理实践，对老年痴呆患者可能遇到的各种问题及应当采取的护理干预措施进行了总结，认为科学、合理和充满人性化的护理干预可以在维持患者的日常生活自理能力、改善患者的生活质量等方面起到积极有效的作用。     

中药对停联苯双酯后ALT复升的疗效

多年来人们普遍运用联苯双酯控制ALT的升高，但停药后，约半数以上的患者ALT复升。1990年以来应用中药治疗联苯双酯降低ALT停药后的复升，取得了较为满意的疗效。现报道如下。1临床资料76例均为门诊病例，随机分为两组。中西药组49例，其中男42例．女7例，平均年龄34．5岁；已婚11例，未婚38例；ALT最高480if，最低88ti，平均219．45U；＊＊T平均异常时间18个月。其中乙肝4］例，丙肝4例，两型混合感染4例。中医辨证脾虚湿重型18例，肝肾阴虚型31例。西药组27例，其中男24例，女3例，平均年龄32．6岁；已婚10例，未婚17例；ALT最高46…
