Results In 84 cases of nerve root type,stenosis was found in 438 intervertebral foramen,of which C6～7 and C5～6 intervertebral foramen stenosis accounted for 79.6%.The causes of intervertebral foramen stenosis were uncinate process articulation hyperosteogeny,intervenebral disc protrusion,vertebral body hypertrophy,zygapophysis hyperosteogeny and dislocation etc.40 cases of vertbral artery type manifested that vertbral artery became slim and deviousness as a result of the compression of vertbral artery （20.7%） by osteophyte.22 cases of myeloid type manifested with cervical spinal canal stenosis,hyperosteogeny of posterior vertebral body edge,posterior longitudinal ligament calcification and cervical intervertebral disc protrusion etc.

结果 84例神经根型中，发现椎间孔狭窄438处，其中C5～6和C6～7椎间孔狭窄占79.6%，椎间孔狭窄的成因有钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生、错位等；40例椎动脉型表现为骨赘压迫椎动脉（52.5%），导致椎动脉变细、粗细不均和椎动脉迂曲。22例脊髓型表现为颈椎椎管狭窄、椎体后缘骨质增生、后纵韧带钙化、椎间隙狭窄和颈椎间盘突出等。

A 3 cm long segment was removed from the middle part of the rabbit radius to make a bone defect model. The periosteum was reserved and restored to set up a vascularized tubulate periosteum graft.

将兔双侧桡骨干中段切除 3cm制成骨长段缺损模型，保留切骨段骨膜，重新复原缝合后作带血运骨膜管移植模型。

Results:①The center of the homogeneous density soft tissue masses (mean CT value was 50HU) were located in the middle and lower tympanum,and the external auditory canal or the pharyngotympanic tube was involved in the earlier period;②the destructed b...

结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。

The indirect decompression mechanism of the pedicle screw open the fracture vertebral and intervertebral discs ,strain posterior longitudinal ligament and intervertebral discs annulus tibrosus ,and push the bone pieces in the vertebral canal ahead to reduct, this process is Ligamentotaxis ,It is function depends on the completement of posterior longitudinal ligament and intervertebral discs annulus tibrosus.

椎弓根螺钉间接减压机制是通过椎弓根螺钉撑开损伤部椎体与椎间盘，紧张后纵韧带与椎间盘纤维环，将凸入椎管的骨块推向前方而复位，称为韧带整复。

Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.

对经曲面断层片筛选出的18例19枚埋伏牙进行牙科三维CT检查，扫描层厚1.0mm，重建后进行图像三维断面显示（包括水平位，矢状位，冠状位），对牙位图像进行分析及测量（包括埋伏牙牙长轴的角度，牙根弯曲度，牙冠的最大径，与骨皮质的距离，与邻牙根、神经孔／管的距离；骨质的厚度、高度等）。

Results: The animal experimental model indicates the facial nerve' s bone canal fracture can make the facial nerve hyperaemia, strut, and putrescence, denaturalization and with the Schwann cell and the cell become more and more, taking on the restore evidence.

结果 动物实验表明：面神经骨管骨折后，面神经发生充血肿胀，并出现脱髓鞘、变性及坏死的变化，伴随神经损伤的同时出现巨噬细胞和施万细胞增生肥大及纤维母细胞的增生，呈现修复迹象。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.
