The ability of melanoblasts in the Silkie embryos to migrate ventrally is correlated with a lack of peanut agglutinin binding barrier tissues, which are present in the Lightbrown Leghorn embryos.

丝羽乌骨鸡的黑色素母细胞之所以可以移动至腹部是由於其缺少了神经阻碍物分子，而此神经阻碍物分子在棕色来航鸡的胚胎发育过程中，会明显地形成一道障壁以抑制神经嵴细胞和黑色素母细胞入侵胚胎腹部。

BP neural network based on adaptive UKF is introduced in this paper for the standard BP neural network has slow converges,local minimum value and weak generalization ability.It can train weight of BP and improve the efficiency of BP without linearization by using the frame of Kalman filters and adaptive factor to adjust the variance of dynamic model.

1引言1986年，Rum elhart和M cC lelland等人在多层前向神经网络模型的基础上，提出了误差反向传播学习算法(BackPropagation简写BP)，该算法是目前在神经网络中应用最广泛的算法，它解决了多层前向神经网络的学习问题[1]。

The practicality of using rough set to reduce the date was discussed, in this paper, and the interval-valued continuous attribute discretization by applying self-organizing map neural network clustering was proposed, too. This article proposes a simplified indiscernible matrix's method, which reduces the example's condition attribute and eliminates the redundant information of the date. What's more, it provides the methods used to diagnosis compressor's faults based on the intelligence hybrid system by adopting the MATLAB neural network workbox. At last, the functional modules which make up into intelligence hybrid system for fault diagnosis was introduced, including: data acquisition module, date preprocessor module, date reduction module, neural network module, fault diagnosis module and fault expressing module. Here, the article also gives the flow of work of all the above modules.

结果表明：注射HRP于大鼠动眼神经核内直肌亚核后，在对侧展神经核区以及前庭神经核、脑桥旁正中网状结构中发现HRP单标记细胞；在前庭神经核内，可见HRP单标记、GABA阳性和HRP/GABA双标记三类神经元，其中HRP/GABA双标记细胞占HRP标记细胞总数的47.1%。

Previous studies have revealed that aganglionic or morphological and numerical abnormalities of the intestinal intramural ganglia may contribute to the pathogenesis of the intestine motility obstacle of them.

目前认为HD和HAD肠动力障碍的发病机制主要是病变肠段粘膜下神经丛和肌间神经丛的神经节细胞的缺失和减少，病变肠壁内的副交感、交感及第三类神经系统均有改变。

The pcDNA〓-apoE〓 plasmid was transfected to SK-N-SH Neuroblastoma cell by liposome. It could be screened by G〓. The immunohistochemical assay was shown that neuroblastoma cell transfected by pcDNA〓-apoE〓 expressed the recombinant apoE protein. The intracellular expressed recombinant protein could inhibit the death of neuroblastoma cell induced by beta amyloidal peptides 25-35 fragment.

用pcDNA〓—apoE〓真核表达载体与脂质体共转染神经成纤维胶质瘤细胞，用G〓选择压力筛选，细胞免疫荧光检测表明，pcDNA〓—apoE〓转染的神经成纤维胶质瘤细胞表达了apoE〓重组蛋白，这种内源性的apoE〓重组蛋白对25μM Aβ25—35多肽诱导的神经成纤维胶质瘤细胞的死亡具有拮抗作用。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

结果：轻度牵拉组牵拉侧前角个别神经元稍肿胀，神经元及神经纤维形态基本上正常，个别白质小片状脱髓鞘样改变，神经根髓鞘和轴索轻度水肿，脱髓鞘不明显；中度牵拉组白质有脱髓鞘改变，神经纤维排列紊乱，轴索崩解、断裂；灰质神经元水肿明显加重，前角运动神经原细胞尼氏体消失，核固缩、深染，神经根髓鞘和轴索水肿，局部轻度脱髓鞘改变；重度牵拉组牵拉侧白质为不规则的大片脱髓鞘区，前角运动神经元胞体固缩、变形、核深染，神经根有髓神经纤维萎缩、数目减少，重度脱髓鞘改变。

In the four placebo-controlled studies evaluating radiofrequency denervation outcomes in patients with "confirmed"l-z joint pain, the only study that screened patients with MBB demonstrated positive outcomes,157versus only one of three that used diagnostic intraarticularin jections.158–160 Ultrasound-guided medial branchand intraarticular blocks have also been demonstrated to provide comparable accuracy to fluoroscopically guided injections, although they may be less likely to detect low-volume intravascular uptake and are less accurate in obese patients.161–164 Because MBB are technically easier to perform than intraarticular injections and involve anesthetization of the nerves to be lesioned, it seems more logical to use these blocks as a prognostic tool before radiofrequency denervation.

在四个设有安慰剂对照的对于&确诊&小关节疼痛的患者行射频神经消融后的结果的研究中，唯一一个用MBB筛选研究对象的实验表现出阳性结果，而其他3个用关节内注射筛选的实验中只有1个表现出阳性。超声介导下的内侧支关节囊内阻滞被证实较透视介导更精确，虽然其血管内吸收剂量较低且在肥胖的患者中精确性较差。由于MBB较之关节内注射技术上更简单，且能对受损神经进行麻醉，利用这种阻滞作为神经射频消融前的诊断方法较为合理。

Methods Microanatomy and red-and-blue latex injection transpa rency method were applied to study ①The medial antebrachial cutaneous nerve, the lateral antebrachial cutaneous nerve and their nutrient vessels;②The relationship between the basilic vein and MACN and its nutrient vessels; and ③The relationship between the cephalic vein and LACN and its nutrient vess els.

The aponeurosis bicipitalis lay in deep of the basilic vein, which separated the basilica vein from brachial artery and the median nerve. In addition, the basilic vein could cross above or below the medial antebrachial cutaneous nerve.

贵要静脉深面是肱二头肌腱膜，此腱膜将贵要静脉与肱动脉、正中神经隔开，贵要静脉可跨过前臂内侧皮神经，前臂内侧皮神经亦可跨过贵要静脉。

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。
