The spraying control system aiming at weed based on machine vision was designed and developed. The index of 2G-R-B is used for segmentation and the method of improved pixel lateral histogram is used for extracting the center of crop row,the method of threthold is also used for identificating between-row weed and BP ANN based on fratal and texture is used for identificating in-row weed. PLC correspondence and performing procedure is desi -gned and developed.

设计和开发了基于机器视觉的麦田除草剂对准喷药控制系统，该系统的视觉子系统首先用过绿的2G-R-B进行植物与土壤背景的分割，其次用改进像素直方图法识别作物中心行，用阈值法识别行间杂草区域，用BP神经网络基于分形和纹理的共同特征识别行内杂草区域，设计并开发了计算机与PLC的通信程序，设计了PLC的运行程序。

"Apraclonidine, a selective alpha-2-agonist, was developed to lower intraocular pressure and minimize the systemic side effects associated with the use of its parent drug, clonidine," write Patrick Watts, MBBS, MS, from the University Hospital of Wales in Cardiff, United Kingdom, and colleagues."An investigation of the site of action of apraclonidine incidentally uncovered a reversal of anisocoria in patients with absent sympathetic innervation of one pupil due to its alpha-1-effect on a pupil with denervation supersensitivity.... The easy availability of apraclonidine, its mild alpha-1-agonist activity, and its hitherto benign safety profile has encouraged its use as a first-line drug in the diagnosis of oculosympathetic paralysis."

英国加地夫市威尔斯大学附设医院的外科学硕士Patrick Watts及研究同仁指出，Apraclonidine是一种选择性的α-2-拮抗剂，是用来降低眼内压，并减少其母系药物降保适使用上的相关全身性副作用；在一项针对apraclonidine作用位置的研究中，因其单侧瞳孔神经切除之α-1-效应，而附带提出单侧瞳孔无交感神经支配患者之瞳孔大小不等为可逆转，apraclonidine之高可利用率，其轻微的α-1-拮抗活性，以及迄今良好的用药安全档案，更强化其作为视交感神经瘫痪诊断第一线药物的使用率。

Parkinson's disease is a kind of a progressive neurodegenerative disorder, which is caused primarily by selective degeneration of dopaminergic neurons in the substantia nigra pars compacta. The symptoms of PD include tremor, hypokinesia, and rigidity, caused by the depletion of dopamine in the striatum.

帕金森氏症是目前临床常见的神经退化疾病之一，目前对於帕金森氏症的药物治疗，主要是额外提供多巴胺或增加脑内多巴胺的停留时间，以减缓患者的症状，然而这些治疗方法皆无法减缓多巴胺神经细胞的持续性退化。

The rat hindlimb representation of S1 area is likely to have at least 2 patterns of neural circuits on brain slices: one is the intracortical circuit formed by interlaminar connections from layers II-III, and the other is the thalamocortical circuit mediated by afferent connections from layer IV.

相反，在II-III层，同样的强直刺激并未能明显诱导LTP的发生。结论大鼠S1区的后肢代表区似乎存在两种不同类型的神经回路，一种是由层间联系介导的皮层内回路，另一种则是由丘脑皮层传入介导的丘脑皮层连接回路。

Results: ApoD was observed positively expressed in type2 astrocytes and oligodendrocytes from O2A lineage, while it was not expressed in type1 astrocytes from T1A lineage. Accordingly, we can verify the phenomenon found in the study of T1A and T2A gene different expression profile that ApoD mRNA was highly expressed in T2A and lowly expressed in T1A. Conclusion: It can be concluded that lipid metabolism related genes such as ApoD play important roles in the generation and differentiation of O2A lineage, which closely correlate with internal mechanism of lipid metabolism in the brain and myelogenesis.［Key words］astrocyte(T1A, T2A); oligodendrocyte; O2A lineage; apolipoproteinApoD

我们已采用基因芯片技术在mRNA水平研究两型星形胶质细胞的基因表达谱差异，发现ApoD在2型星形胶质细胞中差异高表达，故本文拟用激光共聚焦双重免疫荧光标记技术进一步在蛋白质水平观察ApoD在体外分化成熟的两型星形胶质细胞以及少突胶质细胞中的表达情况，以期为我们深入研究ApoD等脂代谢相关基因在脑内脂质代谢和神经髓鞘发育机制中所起的作用提供有用的实验依据，依此探讨胶质细胞发生和分化的信号机制。

Precentral gyri thickness more big postcentral gyri in 93 cases.The mean ratio of percentral/postcentral gyri was 1.736 for left hemisphere and 1.652 for right hemisphere.The superior frontal sulci with precentral sulci intersect in 80 cases.At 31 with brain lesion's patients,MR findings with clinical symptom had same location in the brain gyri.

结果 明确判定中央沟位置98例，中央前回的厚度大于中央后回的93例，中央前回与中央后回厚度之比左侧半球：1.736，右侧半球：1.652；额上沟与中央前沟相交的80例，31例患有脑内疾病的磁共振影像病变的位置与临床神经定位是相一致的。

The transmission is conducted in the form of action potentials along the axon of DRG neuron to the presynaptic membrane in spinal dorsal horn. Action potential depolarizes the presynaptic membrane and activates the voltage-dependent Ca〓 channel. The influx of Ca〓 then triggers the release of neurotransmitter.

外界感觉信息以动作电位的形式沿DRG细胞轴突由外周传向DRG细胞在脊髓背角的突触前膜，导致细胞膜去极化，引起电压依赖性〓通道的开放，〓内流介导突触前膜神经递质的释放，从而完成感觉信息由外周向脊髓的传递。

There are many complex factors, such as age, environmental, social, psychological, personal factor and human diseases, etc., affecting the development of insomnia symptoms. Insomnia is one kind of neurology/psychiatry diseases, due to brain overstrains and stresses in the nerve center system, in Western Medicine, while there are approximately two factors that can cause the insomnia symptoms, including the anti-pathogenic- qi deficiency and the pathogenic-factors invasion in Traditional Chinese Medicine.

失眠的原因有年龄、环境、社会心理、身体疾病等繁多复杂因素所造成，西医学认为失眠是由大脑压力所造成脑与神经所支配命令的自律神经系统降低或失去其调整身体功能作用之中枢神经系统失调的疾病症状，然而，中医学的失眠病因病机可概括为正虚、邪扰两种，其中正气虚涉及心、脾、肝、胆、肾、胃等脏腑，邪气扰则以痰、热、火、饮、食为多，失眠的病因主要有脏腑虚损、精血不足、神魂失养、七情所伤、内邪滞扰、外邪所感、思虑劳倦太过或暴受惊恐，亦可因禀赋不足、房劳久病或年迈体虚等所致；失眠的主要病机在於阴阳及气血失和，脏腑功能失调，进而神明被扰、神不安舍所致。

In this five-step, the evolution of the first step in the series of groups of animals very strange: 14 more haikou insect specimens comparative anatomy studies show that, they not only, and the lack of chordomas in skin, muscle, breathing, circulation, neural organs such as the system with the fundamental difference between the existing chordates, One of the most distinctive is the gills of six foreign composed of respiratory system, and this is the mouth of higher animals in the gills.

在这分&五步走&的演化系列中，&第一步&的动物类群十分奇特：对1400多枚海口虫标本进行比较解剖学研究表明，它们不仅缺少脊索构造，而且在皮肤、肌肉、呼吸、循环、神经等器官系统上与脊索动物存在着根本区别；其中最为独特的是其由6对外鳃组成的呼吸系统，这与较为高等的后口动物的内鳃迥然有别。
