The lesion, the changes of activity of cholinesterase and acid phosphatase of motor neurons in lateral nucleus of spinal cord anterior horn, the function of axoplasm transportation and nerve conduction, the regeneration of axons and myelin sheath, and the recovery of sciatic nerve function were examined at 7, 14, 30 and 90 days intervals after operation, using Nissl and enzyme histochemistry staining, electrophysiological technique, hydrogen-peroxide oxidoreductase retrograde trace method, axon image analysis, and measurement of sciatic function index. The spinal cord anterior horn of injury side was compared to the correspondence region of spinal cord.

分别于术后7、14、30和90d应用酶组织化学方法、电生理方法、HRP （hydrogen-peroxide oxidoreductase）逆行示踪方法、轴突图象分析方法以及坐骨神经功能指数（sciatic nerve function index，SFI）测量等方法检测坐骨神经损伤后对应脊髓神经元的存活率、神经元胞体酶系变化、损伤神经在轴浆运输、电传导以及轴突、髓鞘再生等方面的恢复情况，探索外周神经损伤后OECs及几丁质对神经元的保护作用以及对新生神经功能恢复的作用，为外周神经损伤的治疗提供新的理论基础。

Extraembryonic /ex·tra·em·bry·on·ic/胚外的 adj.Definition : Located outside of the embryonic body. External to the embryo proper, as the extraembryonic coelom or extraembryonic membranes.

部分神经细胞在轴突外围会被一些我们称为髓鞘细胞的细胞包围住，髓鞘细胞可使得神经细胞的冲动传递速度加快，因而形成跳跃式传递。

And wide gaps appeared between axon and myelin sheath, and between layers of myelin shea.

可见轴突与髓鞘间及髓鞘板层间形成宽大的裂隙。

And large gaps were seen between axon and myelin sheath and intermyelin sheath layers.

可见轴突与髓鞘间及髓鞘板层间形成宽大的裂隙。

To explore the mechanism of neuron development retardation and myelination abnormality caused by alcohol,the membrane lipid fluidity of astrocytes and oligodendrocytes which is related to neuron and myelin development were measured by using DPH fluorescence probe.

为探讨酒精所致的神经元分化成熟迟滞和髓鞘形成受阻机制，本文以DPH荧光探针研究了酒精对与神经元和髓鞘发育相关的星形胶质细胞、少突胶质细胞膜脂质流动性的影响。

Methods: Internodal length, the densities of myelinated fiber and unmyelinated fiber, g ratio(axon diameter:fiber diameter) of sural nerves from 7 peroneal muscular atrophy patients were measured and compared between HMSNⅠand Ⅱ.

测定7例腓骨肌萎缩症（遗传性运动感觉神经病，HMSNⅠ和Ⅱ型）患者腓肠神经的节间长度、有髓纤维和无髓纤维的密度以及轴突直径与纤维直径之比，并比较HMSNⅠ和Ⅱ型间上述参数的差异。

BACKGROUND: Lumbar degenerative disease has been commonly treated with nucleus pulposus extirpation or nucleus pulposus extirpation combined with internal fixation; however, with the development of non-rigidity fixation, interspinous dynamic stabilization and intervertebral disk displacement attract more and more attention.

摘要背景：在早期，腰椎间盘退变性疾病的治疗临床常用髓核摘除或髓核摘除加刚性内固定融合技术，但是随着非刚性固定技术的发展，棘突间稳定系统固定和全椎间盘置换在脊柱非融合治疗中逐渐受到人们的重视，其优点日益突出。

Twenty patients were treated with nucleus pulposus extirpation alone, considering as control group; while, other 20 patients were treated with nucleus pulposus extirpation combined with Wallis interspinous dynamic stabilization, considering as experimental group.

选择2007-12/2008-12华中科技大学附属同济医院骨科收治的腰椎退变性疾病患者40例，随机选取20例行单纯髓核摘除，20例行突出髓核摘除加棘突间稳定系统Wallis固定。

At midgestation, cortical axonal tracts in the emerging white matter were PSA-NCAM+, but they were not yet myelinated, based on the lack of myelin basic protein immunoreaction.

妊娠中期发生的皮质轴突束是PSA-NCAM+的，但是还没有髓鞘，因为缺乏髓磷脂碱性蛋白的免疫反应。

They were divided into three groups:nonfusion, posterolateral fusion and intervertebral fusion. After a long term follow-up (≥2y),their clinical data were reviewed to compared their improvement rate of lower back pain,JOA score , subside rate of disc height and chang rate of superior intervertebral space angle.

从2001年5月～2005年8月手术治疗74例单纯髓核摘除术后腰突症复发的患者，将患者分成3组：全椎板切除髓核摘除组，后外侧融合组和后路椎间融合组，经过长期随访(≥2年)，复习其临床资料，比较各组间的下腰痛JOA评分改善率，椎间高度下降率以及上一椎间隙角的改变率，从而比较不同术式的长期疗效。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
