肱骨髁间骨折的手术治疗

肱骨髁间骨折一直是创伤骨科中较难治疗的关节内骨折之一.处理方法有非手术治疗、手术复位和广泛内固定.60年代以前非手术治疗是此类骨折处理的主导,现在倡导的治疗原则早期手术.关节面解剖复位,坚强内固定,早期功能练习.由于内固定材料和暴露方法的改进,手术复位加强内固定的方法已被广泛接受.自2003年6月～2007年2月,作者所在医院采用切开复位内固定手术治疗肱骨髁间骨折25例,取得了较好的临床效果.现报告如下……     

外源性腺苷对缺氧缺血性脑损伤新生大鼠一氧化氮的影响

腺苷(Adenosine，ADO)是一种作用较强的神经调节因子，在缺氧缺血性脑损伤的病理生理中起着重要的作用。为了探讨其作用机制，我们制备了新生大鼠缺氧缺血性脑损伤的动物模型，并给予不同浓度的外源性腺苷，观察其对一氧化氮(NO)、丙二醛(MDA)的影响，探讨其作用机制。     

无缝线角膜切口的二期人工晶体双襻固定术

目的 探讨无需缝线的小切口折叠式人工晶体进行人工晶体睫状沟固定术治疗效果。方法 对12例(12只眼)患者进行无需缝线的角膜小切口折叠式人工晶体进行人工晶体睫状沟固定术。结果 术后效果良好，术中并发症少，未见术后并发症。结论 使用折叠式人工晶体行二期无需缝线的小切口人工晶体植入术，使得手术切口减小，手术安全，术中易于操作。同时术口封锁不需缝线，手术时间明显缩短，并发症少。     

体外超声吸脂术治疗体表多发性脂肪瘤

脂肪瘤是临床上比较常见的良性肿瘤，通常好发于皮下，常见于颈、肩、背及四肢等处，可以呈单发或多发。通常单发者可以手术切除，而多发或巨块形者则治疗比较困难。我们对体表多发性脂肪瘤的患者应用体外超声吸脂减肥技术进行治疗。两年来共治疗了6例患者，收到了明显的效果。

显微外科技术针头支架法输精管吻合术42例分析

目的探讨输精管吻合术的新方法及复育效果。方法通过显微外科技术针头I临时支架固定法，行输精管吻合术42例。结果42例输精管吻合术，术后随访，检查精液有精子36例，术后再通率85．7％；配偶受孕25例，复孕率59．5％。结论应用显微外科技术针头临时支架法行输精管吻合术，可有助于提高输精管再通率复育率。     

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.
