The rabbits were sacreficed in groups 20, 40, 60, 90, 120, or 180 days after operation, and the silicon and aluminium contents in iliac bone and gluteus medius muscle on both sides were determined by inductively coupled plasma atomic emission spectrometry.

本实验在家兔骼骨处植入氧化铝材料后，分别观察骼骨和臀中肌内的铝、硅元素变化及其释放情况，报道如下。

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。

Methods:Radiography,CT and MRI of 27 patients with osteosarcoma was analyzed related with observation of operation and pathology,and the imaging features of metaphysis and joint involved was summarized statistically with Fisher′s test.

对照术中大体观察和术后组织病一学检查结果，对2 7例骨肉瘤患者的X线、CT和MRI所显示的骨骺和关节受侵情况进行分析，总结有关影像学特征。

Wingless proteins and bone morphogenic proteins appear to play a central role in the ''plus'' variant of inflammatory bone remodeling.

Wingless蛋白和骨形成蛋白在&plus&型炎性骨重塑中似乎起着核心作用。

Cortical onlay grafts, first described for the treatment of femoral periprosthetic fractures by Chandler and Tigges,2 are an attractive option because they combine fixation with the potential to restore the bone stock and increase cortical strength, as shown in several studies.

皮质骨加盖移植，Chandler and Tigges[2]最先描述其用于治疗股骨假体周围骨折，这是一个很被人看好的选择，因为这一方法将固定和修复骨干增加皮质骨强度的可能性结合了起来，这在几项研究中得到了证实。

Cortical onlay grafts, first described for the treatment of femoral periprosthetic fractures by Chandler and Tigges,2 are an attractie option because they combine fixation with the potential to restore the bone stock and increase cortical strength, as shown in seeral studies.

皮质骨加盖移植，Chandler and Tigges[2]最先描述其用于治疗股骨假体周围骨折，这是一个很被人看好的选择，因为这一方法将固定和修复骨干增加皮质骨强度的可能性结合了起来，这在几项研究中得到了证实。

Objective To evaluate CT scanning in the diagnosis of the traumatic abnormalities of ossicular chain.

目的 分析 33例外伤性听小骨异常的CT表现以探讨CT在外伤后听小骨异常诊断中的重要意义。

Methods Immunohistochemical method was used to detect the expression of survivin,Cox- 2 in 38 osteosarcoma tissues and 20 osteochondroma tissues.

应用免疫组化SP法检测38例骨肉瘤组织、20例骨软骨瘤组织中survivin，Cox-2的表达。

应用免疫组化SP法检测38例骨肉瘤组织、20例骨软骨瘤组织中COX-2和Fas的表达。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
