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.     

腰、双下肢先天性环束带畸形致死胎1例

患者,女,32岁,农民,因腰及双下肢软组织束带状畸形入院。患者出生后腰及双下肢即有一索条状软组织狭窄,形如腰带,双小腿亦有数条软级织狭窄(附图),否认外伤及襁褓中绳索栓勒史。因无不适,故从未就医。1年前患者妊娠6个月时在当地医院检查,母子均健,至妊8个月时自然娩出一死婴,疑为腰部束带压迫所致。现再次怀孕4个月余,要求解除束带畸形     

剌玫果对烹饪油烟引起小鼠骨髓PCE微核率增高的影响

本文研究了剌玫果对烹饪油烟引起的小鼠骨髓嗜多染红细胞微核率的影响。结果表明，烹饪油烟各实验组的小鼠骨髓嗜多染红细胞微核率明显高于阴性对照组（Ｐ〈０．０１），且呈现剂量－反应关系，剌玫果明显降低烹饪油烟诱发的微核率。     

动脉灌注灭活再植治疗骨肉瘤的体会

本组１２例骨肉瘤均采用动脉区域灌注灭活再植及术后化疗方法，术后２年存活率平均为７５％，１例因经验不足致局部复发，仅占８．３％，表明在化疗保障下，采用此种方法即能保肢，又能获得与截肢治疗相同的手术效果，优于单纯行灭活再植术后中方法。     

胃癌D17S261和D17S799位点二核苷酸重复序列不稳定性的意义

目的研究二核苷酸重复序列不稳定性〔ＤＲＳＩ〕在胃癌发生中的作用及其临床意义．方法采用ＰＣＲ方法检测了Ｄ１７Ｓ２６１和Ｄ１７Ｓ７９９位点二核苷酸重复序列不稳定性．结果胃癌总ＤＲＳＩ发生率为３４％（１７／５０），其中高中分化腺癌ＤＲＳＩ阳性率（６６７％，１０／１５）显著高于低分化癌（１９４％，６／３１，Ｐ＜００１）；肠型胃癌ＤＲＳＩ阳性率（５５６％，１０／１８）显著高于胃型胃癌（２０％，６／３０，Ｐ＜００５），ＤＲＳＩ与胃癌部位、大小、浸润、分期、淋巴结转移无显著相关．结论ＤＲＳＩ在胃癌的发生中可能起重要作用．
