In thisstudy, we sought to determine the number of injections neededto provide a reasonably complete anesthesia of the upper limbwith this approach. Seventy-five patients were randomly assignedto receive a coracoid block guided by nerve stimulator with42 mL of 1.5% mepivacaine with a single-injection (Group 1),dual-injection (Group 2), or triple-injection (Group 3) technique.

在本研究中，我们拟探讨为提供完善的上肢麻醉效果所需要的锁骨下臂丛神经阻滞的注射次数。75例病人用神经刺激器指导喙突旁臂丛神经阻滞，随机用1.5%的甲哌卡因42ml 行单次注射（组1）、分两次注射（组2）或分三次注射（组3）。

10 healthy subjects received linear acceleration, continuous Coriolis acceleration and discontinuous Coriolis acceleration stimuli on different dates.

对10名健康被试者，在不同日期分别进行了线性加速度刺激、连续的科氏加速度累积刺激和间断的科氏累积加速度刺激，刺激的终止指标以被试者感觉有轻度植物神经症状为准。

In recent years, rTMS has also been used as a therapeutic tool in a variety of neuropsychiatry disorders such as Parkinson disease and depression that were conceptualized in term of a dysfuction of neuronal circuits and neurons at a cellular and molecular level.

近年来rTMS更是在治疗一系列的神经精神疾患如帕金森病、抑郁等上取得了较好的效果，但其治疗机制尚不明了，而且这些神经精神疾病又被认为是神经环路和神经元在细胞及分子水平上的功能失调，因此探讨rTMS所致的磁刺激对中枢神经系统中神经元基因活性、神经介质或/和调质、结构变化等的调控作用有着重要的意义。

Methods The clinical application of 25 normal subjects were stimulated at 1Hz at stimulus intensities corresponding to threshold, recording from the abductor pollicis brevis muscle belly.

25例健康个体，于正中神经腕点处刺激，在拇短展肌肌腹内接收，刺激频率为1 Hz，刺激强度为阈强度上下。

With the interval of magnetic stimulation at tuberosity of occipital bone and electric stimulation of ulnar at wrist joint, amplitude of F-wave was lengthened and course was delayed.

枕骨粗隆处磁刺激明显改变了脊髓前角细胞兴奋性，表现为当枕骨粗隆处施行的磁刺激和腕关节处尺神经电刺激间隔一定的时间时，F波波幅增高，时程延长。

Median nerve or deep peroneal nerve stimulation could inhibit completely or partially the deflection of ischemic ECG ST segment due to stimulation of dorsomedial hypothalamic nucleus.

电刺激正中神经和腓深神经均能抑制或部分抑制下丘脑背内侧核诱发的缺血性心电ST段偏移，以刺激MN更为明显。

BACKGROUND: In this study we evaluated the minimum stimulatingcurrent associated with intraneural needle placement and sonographicappearance of intraneural injection.

背景：本实验作者评估了神经内刺激针最小刺激电流神经内注射的超声像图。

The distance between the skin which the needle stab into and the ligamentum, is (72.2±0.2)mm and between the skin which the needle stab into and the pudenda nerve is (80.2±0.1 ) mm. Conclusion: We should have a specific depth and angle when acupounct into the acupoint of Zhenyang, to make it sure to get the specific feeling of acupunting. The main reason of getting the specific feeling of acupunting is the needle may touch the pudendal nerve.

针刺&振阳穴&产生特殊针感可能是由于直接刺激到了阴部神经，或由于针刺时引起局部肌肉组织收缩牵拉刺激阴部神经所产生的，治疗阳痿的作用机制可能是通过调节大脑皮质和脊髓节段反射来影响阴茎勃起功能的。

Artificial neural network is a fast developing intercrossed subject. The theory of ANN make the transmitting of large information and complex calculation possible. ANN is not only a highly non-linear dynamics system but also a self-organization and self-improvement system. In the early 1980's, the appearance of ANN dramatically promote the primary research on understanding and intelligence of human-being as well as the computer industry.

人工神经网络是一门发展十分迅速的交叉学科，神经网络理论是巨量信息并行处理和大规模平行计算的基础，神经网络既是高度非线性动力学系统，又是自适应组织系统。80年代初，神经网络的掘起，已对认知和智力本质的基础研究乃至计算机产业都产生了空前的刺激和极大的推动作用。

Methods Three adult rat models were set up, including the model of total left brachial plexus root avulsion injury, the nerve transfer model of contralateral seventh cervical nerve root to median nerve, as well as the callosotomy model.

结果： 1、成年大鼠全臂丛根性撕脱伤后：（1）在双侧SmI记录SEP：不同时间段电刺激患爪正中神经支配区，在双侧SmI 均未诱发出SEP；电刺激健侧前爪正中神经支配区，在健爪同侧SmI未记录到SEP，只在其对侧SmI记录到SEP，且不同时间段的SEP位点数目均明显多于正常对照。

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。
