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.     

椎间盘镜与开放手术治疗老年性腰椎间盘突出症疗效比较

目的 比较椎间盘镜手术(MED)与开放手术治疗老年性腰椎间盘突出症的疗效。方法 采用回顾性分析方法，对31例老年性腰椎间盘突出症患者行MED手术和37例行开放手术患者进行比较研究。结果 MED组优良率为90．0％，开放手术组优良率为89．2％，统计学上差异无显著性。而手术时间和术中出血量，统计学差异有显著性。结论 两种方法疗效相近，但MED组手术时间和术中出血量高于开放手术组，MED不应作为老年性腰椎间盘突出症的首选方法。     

老年人结石性胆囊炎急性发作时腹腔镜手术61例体会

目的探讨老年结石性胆囊炎急性发作时腹腔镜胆囊切除术(LC)的时机和方法。方法总结分析了61例老年结石性胆囊炎急性发作时行LC病例的临床资料。比较发病72h以内(早期)和72h以外(延期)两组的治疗效果。结果全组病例无严重并发症发生，但延期组的平均手术时间、平均术后住院日和平均术后下床活动时间均较长，早期组LC全部成功，延期组中转手术2例(8．7％)。结论老年人结石性胆囊炎急性发作时早期行LC是安全的，延期施行LC要极为谨慎。     

一种基于时间戳协议的电子病历认证方案

时间戳协议是一种基于Hash函数的报文加密协议.本文分析了线性链表和二叉树时间戳协议算法,提出了一种基于时间戳协议的电子病历的认证系统方案.该方案通过对电子病历的数字摘要进行数字签名的方法进行加密,可以在加密的同时降低了对通讯带宽的依赖性.通过分析的抗攻击能力可知,基于时间戳链的上下文相关性,本方案能够有效地防止对电子病历内容及认证时间的修改.
