Strut-graft with an appropriate distraction after corpectomy plays an important role not only in regain and maintain the cervical spine lordotic curvatures but also in acquire the global immediate stability of the cervical spine. After single vertebra corpectomy, the proper range of distraction between the superior and inferior vertebra maybe among 4-6 millimeters.

中下颈椎单椎体次全切除减压后，适当高度的撑开植骨对恢复和维持颈椎曲度以及手术节段的即刻稳定性有重要作用，中下颈椎单椎体次全切除减压后支撑植骨的高度应该是在手术椎体的上位和下位椎体间高度的基础上再撑开4～6mm左右。

In the literature, the incidence of a retroperitoneal lymphocele following surgery is 0.6 to 18% in renal transplantation,3,4,12 20 to 30% in radical surgery with lymphadenectomy for gynecological cancers,2,6,17 and 0.8 to 11% in urological procedures.9,15 There have been several reports on the formation of chylothorax or chyloascites following thoracic or upper lumbar spinal surgery because of injuries to the thoracic duct or cisterna chyli.1,8,16,1821 However, cases of retroperitoneal lymphoceles are extremely rare in lower lumbar spinal surgery.

在文献报导的引起腹膜后淋巴管瘤的手术中，肾移植中其发生率为0.6 到18%，妇科肿瘤淋巴结清扫根治性手术中为20 to 30%，泌尿系中为 0.8 to 11%。也曾经有几篇报导显示胸椎或上腰椎手术造成胸导管或乳糜池损伤引起乳糜胸或乳糜腹水。但是，下腰椎手术造成腹膜后淋巴管瘤则很少见。

Method］from january 2003 to may 2006,32 patients were corrected with qin si-he's orthotics devices on the ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.among these patients,2 were caused by peroneal nerve injury,l by tumor in the vertebral canal,5 by meningocele,11 were caused by poliomyelitis,13 by congenital talipes equino-varus.in accordance with deformities,external fixator and limitied operative methods were dertermined.the limited release of soft tissue were performed in 7 patients,limited osteotomy in 25 patients.the dynamic muscle balance operation were performed in 9 patients with imbalance of muscle strength.according to the ilizarov technique,the fixative rods were installed.the telescopic rods on the apparatus were rotated one week after the operation,the divices had corrective function in three-dimensional directions.the deformity of talipes equinovarus,internal rotation and drooping of the forefoot were gradually corrected,and the patients could bear weight and walked on the deformed foot.the mean duration of traction were 42 days,then removed the external fixator maintained with plaster for a site time.

方法］2003年1月～2006年5月，根据ilizarov张力应力法则，应用秦泗河改良的外固定矫形器，遵循ilizarov穿针固定的基本原则，共手术治疗马蹄内翻足32例，男15例，女17例；年龄10～25岁，平均17岁。病因：腓总神经损伤2例，腰椎管内肿瘤1例，硬脊膜膨出5例，小儿麻痹后遗症11例，先天性马蹄内翻足13例。术前用足掌的前外缘负重行走者11例，用足的外缘或足背外侧负重者21例。根据马蹄内翻足畸形程度、性质和患者年龄，确定实施有限矫形手术的方法和外固定矫形器治疗。本组7例同期实施有限的软组织松解术，25例同期实施了有限的截骨术和跗骨间关节融合术，9例合并踝关节内外翻肌力明显失衡者，同期行足部肌腱转移的肌力平衡术。然后安装外固定矫形器。术后按作者制定的管理程序，7 d开始旋转相应的螺纹牵拉杆，对器械进行三维空间的缓慢调整，先矫正前足内收和后足内翻，后矫正足下垂畸形，直至达到矫形要求的标准。在矫形的过程中定期进行x线检测，以防止发生踝关节前后移位，治疗期间允许患足负重行走。术后平均牵伸42 d，拆外固定器后患足再上石膏固定适当时间。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。

The growth and survival of Mytilus galloprovincialis post-larvae metamorphosed using different chemical compounds were investigated in this study to identify potential inducers in aquaculture and antifouling and biofouling researches.

中文摘要：在以往实验的基础上，跟踪调查了筛选出的化学诱导物质对紫贻贝幼虫变态后的生长和成活率的影响，并比较了其与相同条件下自然诱导物、微生物膜诱导后的稚贝的生长和成活率。

Methods: From February 2002 to June 2006, 27 patients with upper urinary obstruction due to retroperitoneal fibrosis post-treatment of tumor, under went procedures including retrograde ureteral catheterization, intraluminal ureterotomy and/or balloon dilation, and percutaneous nephrostomy. The efficacy and major complications were summarized.

收集本院2002年l月至2006年6月的27例恶性肿瘤经治疗后发现腹膜后纤维化导致上尿路梗阻的患者，分别接受了经尿道逆行输尿管插管、输尿管狭窄内切开和／或扩张及经皮肾造瘘治疗，总结其疗效和主要并发症。

The ureteroscopic holmium: YAG laser lithotripsy can he the first choice for the post-renal acute renal failure associated with upper urinary tract stones, due to its safety and efficiency. At the same time, retrograde intubation under cystoscope and percutaneous nephrostomy will be helpful.

上尿路梗阻是肾后性急性肾功能衰竭的主要原因，如能明确是结石引起的肾后性肾功能衰竭，应首选输尿管镜下钬激光碎石并置管引流；如不能明确，膀胱镜下逆行插管和经皮肾穿刺造瘘引流也是可行的急诊有效方法。

The perpendicular line from neurocanal most lateral to the sa line and sb line were defined as h1 and h2 respectively,the length of Ph1 and Ph2 were measured,the diameter of screw smaller than 2 times of Ph2 lengths was regarded as safe.The line from the first posterior foramen lower end to the second posterior foramen upper end was obtained.

Methods A total of 105 later periods cancer sufferer who had intractable upper abdominal pain were included, in which 67 accompanied with extensive retroperitoneal lymph nodes and celiac plexus involvement fusing masses. Ethanol was injected through neurolytic celiac plexus block with the needle tip positioned into masses fused by lymph nodes.

Results The neuronic apoptosis in cortex and hippocampus appeared at 6 hoursafter HIBD, peaked at 24 hours, and then decreased gradually, There was a remarkable lower quantity in melatonin treated groups compared with HIBD group at 6h,12h,24h,48h and 72h (p0.05), but there were significant differences between theirs and after HIBD2 hours groupp

结果：TUNEL法显示皮质和海马神经元的凋亡于缺氧缺血后6小时开始出现，24小时达高峰，然后逐渐下降，MT治疗组组间存在差异，但各组在6小时、12小时、24小时、48小时、72小时均显著低于HIBD组(p0.05)，但它们与HIBD后2小时组在各项指标的变化上均有显著性差异p
