Especially, the number of type Ⅰ complex terminals which come from unmyelinated afferent fibers recovered to the level of unoperated side. It indicates that morphine may promote the collateral sprouting and synaptic reinnervation of primary afferent fiber, unmyelinated afferent in particular. 4. Although the collateral sprouting and synaptic reinnervation were shown also in spinal cord of operated side in 34 days spared root rats, they were slower than that of morphine spared root group.

表明吗啡促进了备用根初级传入纤维，特别是无髓纤维更快地向L〓脊髓段侧支出芽，稍后在L〓平面脊髓内侧支出芽以及突触重建。4、34天备用根大鼠术侧脊髓内也有侧支出芽和突触重建，不过侧支出芽的速度要比吗啡组慢。5、电镜定量结果也显示，吗啡备用根大鼠和备用根大鼠术侧备用根的无髓纤维数比备用根大鼠非手术侧的分别增多60％和42％。

BACKGROUND: Implantation of artificial joint of bone cement can result in long-term blocking of recipient site medullary canal and blood vessel lesion, and lead to changes in intraosseous pressure and bone blood flow of distal femoral shaft.

背景：骨水泥固定型人工关节假体骨腔内的植入必然涉及受区骨髓腔的长期闭塞和髓内血管的破坏，由此而产生的髓内压和血流的变化是材料本身的影响所致，很有研究价值。

When surgery is indicated after central cord injury in the stable spondylotic spine, it is the overall cervical spinal alignment and the number of levels affected that determine the surgical approach.30 When the spine is lordotic, and particularly when there are multiple levels of compression; a posterior approach, either a laminectomy and fusion or a cervical laminoplasty are recommended approaches.28 If the spine is neutral or slightly kyphotic, then occasionally, after a posterior laminectomy, lordosis may be achieved with intraoperative positioning and maintained with posterior lateral mass fixation and fusion.

当不伴有颈椎不稳的颈椎病并颈髓中心管损伤患者需要手术治疗时，整个颈椎的序列和受累的节段决定了手术入路的选择。颈椎处于前凸状态，尤其是多节段颈髓均有受压时，建议采用后方入路进行全椎板切除融合或颈椎椎板成形术。假如颈椎处于中立位或稍微后凸时，有时通过后方的全椎板切除，术中复位和侧块螺钉固定融合，可以恢复颈椎的前凸。

Human neurotropic JC virus is able to infect human brain glial cells. The causative agent of the fatal human demyelinating disease progressive multifocal leukoencephalopathy, that cytolyses and destroys oligodendrocytes, the myelin-producing cells of the central nervous system. Also results from several experiments have indicated the JCV is able to induce neoplasms.

人类嗜神经性JC病毒可感染人类脑细胞是引起进行性多病灶脑白质病的因素，为一种致命性的脱髓鞘疾病，其导致神经系统产髓质细胞的溶解破坏，但JCV也在许多动物实验上显示其有促成肿瘤的潜在性。

Results:Three important MRI feat ures of brain stem gliomas were found:①enlargement of brain stem contour.Using different sequences and planes the precise tumor location could be obtained.Sagittal scan could well display the early stage of brain stem glioma,the tectal glioma and cervicomedullary junction glioma.

结果：MRI表现有以下3个特征：①肿瘤使脑干的外形增大，通过不同序列和断面显示肿瘤的精确部位，矢状面对于显示胶质瘤的早期改变、顶盖部位及延髓颈髓联合部位的胶质瘤具有独特作用。

Part n We counterchecked the patients in one week,, and compared the activity of the pulp with preoperational conditions.

二、采用观察法复查患者。l周后患者来院复查，了解患者1周内是否有不适感，牙髓活力仪检测患者的牙髓活力的变化，并与术前进行比较。
