神经元的

Background: The neuron death resulting from traumatic brain injury can be classified into 3 types:(1)neuron death due to primary injury;(2)neuron necrosis due to secondary injury such as hemorrhage, compression, anoxemia and ischemia;(3)neuron apoptosis due to inflammatory factor, cytokine,, excitatory transmitter, Ca~(2+) overload and oxygen radical et al.

引言创伤性脑损伤所致的神经元死亡主要有三种：①原发性损伤所致的神经元直接死亡；②外伤后出血、压迫、缺血缺氧等继发性损伤因素所引起的神经元坏死；③炎性介质、细胞因子、兴奋性递质、Ca~(2+)超载、氧自由基等因素所诱发的神经元凋亡。

Results showed:(1) The number of ChAc-IR neurons (62. 25±1. 45) in the group of visceral pain increased obviously. The positive neurons (46. 38±1. 27) in the group of electroacupuncture and visceral pain were lower than those of VP (p.05). These indicate that there were changes in cholinergic neurons' activity, increasing of ChAc function and turbulence of intestinal motility in rat's ileum following the acute colonitis.

结果发现：（1）内脏痛组ChAc-IR神经元（62.25±1.45）明显增高，电针+内脏痛组阳性神经元（46.38±1.27）明显低于内脏痛组，二组之间存在显著差异（p.05），提示急性结肠炎可致继发性回肠内在胆碱能神经元活动的改变，ChAc活性增高，肠动力紊乱，而电针可抑制这一改变。

Some structure occur lately, and the neurons emerge earlier, such as the hypoglossal nucleus, nucleus ambiguous and reticular formation.

延髓灰质结构形成和神经元发育分化的规律：有些结构发生早，而神经元分化较晚，如下橄榄核、三叉神经脊束核和孤束核；有些结构发生略晚，但其中的神经元胞体分化和发育则较早，如舌下神经核、疑核及延髓的网状结构；有些结构发生早，神经元发育也早，如迷走神经背核。

The increase of ganglion volume mainly lied in growth of neurons and increasing of nerve fibers and neuroglia cells, but not lied in marked increase of neurons in number.

山羊胎儿脊神经节于胚胎第6周就已形成，但此时节内神经元形态不清晰，至第8周，节内神经元形态逐渐清晰，节内神经纤维数量少；随着胚胎发育，节内神经元数量并不显著增加，而是节细胞之间神经纤维及胶质细胞的增多和神经元个体的增长，从而使神经节的体积逐渐增大。

Pass nerve of pair of layer of different hidden from view yuan numerary considers to discover, when concealed layer nerve yuan amount is achieved 100 when, emulation result and degree of experimental data likeness achieved 90% above, and nerve of the layer that follow concealed yuan number increase, training error drops speed is accelerated, but training rate slows, training time is lengthened.

通过对不同隐层神经元数目的探究发现，当隐层神经元数目达到100时，仿真结果和实验数据相似程度达到了90%以上，且随隐层神经元数目增多，练习误差下降速度加快，但练习速度变慢，练习时间延长。

In this paper, the theory of artificial neural network is summarized; the analyse on BP neural network model is put stress on. For the predominance of artificial neural network"s dealing with non-linear complicated relation, the technology of artificial neural network is introduced into the evaluation of the highway bridge"s carrying capacity; and the preferences , the collection and disposal of stylebook, the structuring of BP neural network model are analyzed.

文中对人工神经元网络理论进行了综述，重点对神经元网络的BP算法进行了分析，利用人工神经元网络处理非线性复杂关系的优势，将人工神经元网络技术引入到公路桥梁承载力评估中；并对其中的参数选择、样本收集与处理、构造BP网络模型等进行了分析。

All major neuropil regions are labeled by 5-HT antiserum except the optic lobes, antennal lobes and calyces of mushroom bodies, which are almost devoid of 5-HT immunoreactivity.

除常规的免疫阳性神经元(仅细胞质被标记的神经元和整个胞体都被标记的神经元)外，我们在前脑中部及触角叶内侧还发现了一些只有细胞核对 5-HT 抗血清发生反应的特殊神经元。

GABA-ergic neuron may involve in the modulation of acetylcholine releasing in spinal cord and in the thermoregulation in preoptic area and anterior hypothalamus,which may lead to the TPM related hypohidrosis.

4GABA能神经元可能参与节前胆碱能神经元调节、GABA能神经元参与丘脑下部对高温的反应。这种参与活动可能与TPM泌汗障碍相关。

The neonatal Wistar rats, clean degree, were used. The hippocampal neuron cells out of 9 rats were cultured and divided into the control groups of before and after hypoxia-oxygenation,and xionggui diwan 1 × 10-6 mol/L and 10 × 10-6 mol/L groups. Xionggui diwan was provided by the 88 Hospital of Chinese PLA and its active ingredient was the volatile ingredient of chuanxiong and danggui.

选择新生清洁级Wistar大鼠1只，取其海马，将其分离培养成海马神经元细胞，然后选取9例海马神经元细胞，将其放入3个培养皿中培养，每个培养皿中3例神经元细胞，将其分为缺氧-复氧前后、芎归滴丸(由解放军第八十八医院制剂室提供，主要成分为川芎和当归的挥发油)1×10-6mol/L组和芎归滴丸10×10-6 mol/L组。

Results: 1 The analysis revealed that GAP-43 immunopositive neurons in rats were localized in all the layers of lateral geniculate nucleus and the layers II -VI of visual cortex area 17,and GAP-43 is stained by a ring and dot figure and brown-yellow colour in cytomembrane ; 2, In the critical period, gene expression concentration and number of GAP-43 immunopositive neurons, in both the lateral geniculate nucleus and the visual cortex area 17, received from the deprived eyes, are reduced.

结果：1、GAP-43在正常大鼠视觉系统表达主要见于外侧膝状体全层和视皮质17区Ⅱ—Ⅵ层神经元胞膜中，呈环状或点状棕黄色免疫阳性反应；2、在敏感期内剥夺眼对侧外侧膝状体和视皮质17区GAP-43表达的免疫阳性神经元染色变淡(P＜0.05)，且免疫阳性神经元数目减少(P＜0.05)。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
