无髓鞘的

In DM group, decreasing of density of axoplasm, deposition of fat droplets, swelling and vacuolization of mitochondria and separation or disintegration in lamellar of myelin sheath of the sciatic nerve fiber could be observed, which could be partially improved by EA and KBK.

电镜形态学分析见造模两个月的糖尿病大鼠坐骨神经髓鞘板层有分离现象，线粒体嵴紊乱，有的线粒体嵴完全消失形成空泡线粒体，轴浆内有大量脂肪颗粒沉积；经电针和渴痹康治疗后能减轻这些病理改变。4。无论是电针治疗还是渴痹康治疗均无明显降血糖作用。

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

给药局部肉眼观察未见明显的纤维组织增生；HE染色可见B、C、D三组给药后四周及八周时硬膜内外均有炎细胞浸润，纤维细胞轻度增生，硬膜外神经根内有炎细胞浸润及炎性渗出；特殊染色B、C、D三组同A组相比未见有脊髓及神经根的改变；免疫组化染色，给药后四周及八周时，硬膜内外均有Ⅱ型胶原纤维增生；固兰染色B、C、D三组未见有明显脱髓鞘改变，与A组相比无明显异常改变；电镜观察B、C、D三组在给药后的四周及八周时，表现为硬膜外神经根内髓鞘厚薄不一，形状不规则，可见成纤维细胞，神经内膜中可见有巨噬细胞；粗大的有髓神经纤维变化明显，无髓神经纤维受累较轻；八周时电镜下D组改变较B、C两组为轻。

We identified a novel NMO lesion in the spinal cord and medullary tegmentum extending into the area postrema, characterized by AQP4 loss in foci that were inflammatory and oedematous, but neither demyelinated nor necrotic.

我们在对脊髓和延髓背盖延伸入最后区的一个异常NMO病灶研究中证实，该病变仅表现为以AQP4缺失为特征的炎性水肿，既无脱髓鞘也无坏死。

RESULTS: Chitin tubes containing NGF successfully induced the nerve regeneration, regularly arranged myelinated and unmyelinated axons could be observed across the 8 mm gaps, and the myelin sheath was thick with clear lamellar structure at 8 weeks after operation, The regenerated nerve fibers increased and were more mature at 16 weeks after operation.

结果 实验侧术后8周，再生神经中有髓和无髓神经纤维排列整齐，有髓神经的髓鞘厚，板层结构清晰；术后16周，再生神经中有髓和无髓神经纤维数量增加，形态接近正常神经。

These clinical presentation were different from that of chronic inflammatory demyelinating polyneuropathy.

RGBS应属多次发作的典型的急性GBS，每次发作之间无明显相关，与慢性炎症性脱髓鞘性多神经病不同，诊断时需认真鉴别。

Result: Schwann-like cells disperse in the hole of nerve graft at oneweek under Scanning Electronic Microscope, the processes of thesatellite-like cells adhere to the wall of graft.There was no statisticaldifference of activity of cells in both group(P＞0.05) using MTT. At 12weeks,the result of appearance, histology and TEM were similar, therewere no statistical difference in SFI%, NEP and quantitative analysis ofrecovery rate of myelinated fiber populations, diameter of myelinatedfiber and thickness of myelin sheat.

结果：1w后扫描电镜下可见接种的类Schwann细胞分散在材料表面的孔隙内，细胞形态为星状，细胞突起与支架管壁粘附；MTT法测定细胞活性示神经支架组在各时间点与对照组无显著性差异P＞0.05；12w时两组动物坐骨神经外观、组织学光镜观察、透射电镜观察结果相似、两组坐骨神经功能指数恢复率、神经电生理、再生有髓神经纤维计数恢复率、神经纤维直径恢复率、髓鞘厚度恢复率等指标相比无显著性差异(P＞0.05)。

The effect of treatment is negatively correlated with the course of disease, generally, the effect is much worse with the course of disease is much longer; The effect is positively correlated with the course of treatment, it is better if the course of treatment is longer.The group of more than one year is much excellent than the group of less one year. The ex-electroencephalogram before treatment is normal, on edge and a little abnormal, the effect is better. As regards CT or MR result, there is difference between the effective group and the ineffective group. The result of CT and MR is negative, the effect is better, and the effect to demyelination and leukoencephalopathy is most worst.However,for the tipe of much abnormality, the effect is the most worst.The effect is related to course of disease.The effect is better if the course is shorter.There is no difference in the tipe of disease the symptoms before episode, the frequency of episode, the inducing reasons, the age, sex and so on.

病程的长短与疗效存在负相关关系，病程越长疗效越差；疗程与疗效存在正相关关系，疗程越长疗效越好；疗前脑电图的异常程度与疗效存在负相关关系，正常、边缘及轻度异常者，疗效较好，重度异常者疗效最差；无效组与有效组在CT及MR检查结果上有差异，有阴性者疗效好，阳性者疗效差，脱髓鞘及脑白质病疗效最差的趋势；疗效与性别无相关性；无效组与有效组在发作类型、既往病史、辨证分型、发作先兆、疗前发作频率、诱因、发病年龄、就诊前所用药物方面无差异。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
