神经发生

Untethering surgery may help decompress and spare functional neural tissue and prevent retethering of the spinal cord.

解除拴系的手术能够起到减压，保护神经功能和防止发生再次拴系的可能。

It is accepted that once the diagnosis of a tethered spinal cord is made untethering is recommended prior to the development of the inevitable deterioration that is seen in the unoperaed patient.

因此我们形成一个治疗规范，一旦诊断为脊髓拴系，建议在没有发生不可逆神经损害前接受手术治疗，这是从不接受手术的患者那里得到的教训。

Preoperative careful evaluation of the vertebral artery seems to be most important to prevent iatrogenic VAI and to avoid postoperative neurologic sequelae.

要想预防医源性VAI及避免术后发生神经后遗症，在术前仔细评估椎动脉是最为重要的。

Fake smiles can be performed at will, because the brain signals that create them come from the conscious part of the brain and prompt the zygomaticus major muscles in the cheeks to contract.

假笑可以随意发生，因为大脑发出假笑的信号，由大脑中的意识部位产生，并促使脸颊中颧肌主要神经参与活动。

However, fully consideration of special structure and physiological function of CRP is critical to investigate whether CRP provide protect effect or pathogenic effect in the progression of atherosclerosis. CRP is a member of pentrxins family, which consists of five identical, noncovalently associated 23-kDa protomers arranged symmetrically around a central pore with a 102 A external diameter. Each protomer has a recognition face with a phosphocholine binding site consisting of two coordinated calcium ions adjacent to a hydrophobic pocket. The opposite face of the pentamer is the effector face, where complement Clq binds and Fc receptors are presumed to bind. A cleft extends from the center of the protomer to the central pore of the pentamer. Both faces ofpentamer form a special bi-phase structure: one face is the ligand recognition phase, which can recognize apoptosis cells and enzyme modified low density lipoprotein in which PCh is exposed.

CRP是一种五聚体蛋白，外径为102 A，由5个相同的单体以非共价键结合，形成双面的环形结构，每个单体的配体识别位点或受体结合位点分别位于五聚体两个平面上，分别组成配体识别相和效应器相，从而构成特殊的二相性结构：一面为配体识别相，含有磷酸胆碱(phosphorycholine，PCh)结合位点，能够使CRP识别在病理条件下暴露出PCh的凋亡细胞、酶修饰低密度脂蛋白(enzyme modified low density lipoprotein，E-LDL)等。E-LDL是天然低密度脂蛋白(native Low density lipoprotein，N-LDL)在多种蛋白酶，如胰蛋白酶、神经氨酸酶、胆固醇酯酶等作用下的代谢产物，其主要特点是结构发生改变(N-LDL大小均匀，平均直径250±30 A，E-LDL大小差异极大，直径为100-2000 A)，暴露磷酸胆碱位点，能够被CRP识别；另一面为效应器相，能够与巨噬细胞、单核细胞表面受体FcγRⅡa结合，介导巨噬细胞、单核细胞识别及吞噬凋亡、坏死细胞作用。

RESULTS: NEC mainly occurred in stomach, pancreas, rectum, esophagus, small intestine, Vater ampullae of duodenum, liver and so on, and it had a wide spectrum of clinical presentations such as abdominal pain, epigastric distention, symptoms of wasting.

目的：探讨消化系统神经内分泌癌发生部位、临床表现、内镜及影像学特点、病理特征、诊断和鉴别诊断、治疗及预后。

All the electrodes were inserted successfully and confirmed intact by electrode impedence testing. csf gusher took place in three of them during the implantation and were stopped by bunging with soft issue and encephalon glue.

A slipped disc occurs when the jelly-like disc of cartilage that acts as a cushion between two vertebrae in the spine, slips or prolapses so it is pressing on the nerves causing the muscles of the back to go into spasm.

椎间盘脱出是由于脊柱两块椎骨中的起缓冲冲击作用的胶状椎间盘软骨发生滑动或脱垂时，压迫椎管内神经引起后背痉挛。在严重的情况下椎间盘软骨不得不通过手术的方法移走，在一些情况下脊柱的骨头被熔合了避免进一步的移动。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
