The epilepsy model induced by kainic acid is a dynamical model condition. 5-7 days after acute seizure episodes induced by a single systemic injection of a convulsant dose (10mg/kg) of KA the rats developed a long-lasting increase in seizure susceptibility and the characteristic histopathological features in the hippocampus similar to human TLE. So the KA model has been a well-known model to study TLE or intractable epilepsy.

颞叶癫癎红藻氨酸（kainic acid，KA）模型具有明确的动态变化过程，一次全身性给予惊厥剂量（10mg/kg）KA诱发SD大鼠急性癫癎发作后5-7天，动物开始出现癫癎发作敏感性长期增强，脑内亦发生与人类颞叶癫癎相似的神经病理、神经生化及神经分子生物学方面的改变，因此被认为是研究颞叶癫癎和难治性癫癎的理想模型之一。

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）。

The useful and important tests of sensibility are: testing the vibratory sensation with tuning fork, vibrometer testing for vibratory thresholds, von Frey testing (determined by Semmes－ Weinstein nylon monofilaments or Pressure－ Specifying Discriminator) for cutaneous pressure thresholds, measurement of static and moving two－ point discrimination with the Disk－ Criminator, Moberg's ninhydrin test, O'Rain skin wrinkling test, Picking－ up test, Tinel's sign and electrodiagnostic test.

此文对临床上重要且实用的皮肤感觉功能测定方法如音叉皮肤振动觉定性检查、振动觉阈的振动器定量测定、Semmes－Weinstein尼龙单丝或Pressure－SpecifyingDiscri minator行皮肤压觉阈的测定、用Disk－Criminator进行静止和运动的两点辨别觉测定、茚三酮试验、O'Rain指腹皮肤皱缩试验、捡物试验、Tinel's征电生理检查以及这些检查方法在神经断裂、神经卡压及神经损伤或修复后的恢复等情况中的应用和评价作一讨论。

For the limitations of the traditional algorithms that can not be reasonably used to predict the traffic, this paper adopted the BP neural network and curvilinear regression coupling algorithms to add the inadequate.

摘 要：针对传统交通量预测方法中的局限性，采用BP神经网络与曲线回归耦合算法，用BP神经网络对历史数据训练，利用曲线回归对各因素待测年份之值进行预测，将各因素的预测值带入已训练好的BP神经网络中，即可得到未来交通量的预测值。

For the limitations of traditional algorithms that can not be reasonably accurately predict the traffic, we have adopted BP neural network and curvilinear regression algorithms. First, we use BP neural network to train on historical data and then use the curve of regression to predict various factors, and then forecast data into the trained BP neural network which has been trained well, you can get future traffic forecasts.

针对以上传统算法的局限性，采用BP神经网络与曲线回归耦合算法，用BP神经网络对历史数据训练，利用曲线回归对各因素待测年份之值预测，将各因素的预测值带入已训练好的BP神经网络中，即可得到未来交通量的预测值。

Objective: Adult rat sciatic nerve was transected and bridged by artificial serve darner graft after one-month defect, and that the dependency changes of the regenerative nerves and the target muscles were investigated.

目的：用人工组织神经移植物桥接缺损l个月的大鼠坐骨神经，观察神经再生以及靶肌肉神经再支配的相关情况。

The mathematical model of the dynamic recurrent neural networks with two hidden layers is introduced. Using the experimental data, the neural identifier and the neural controller are designed off-line.

介绍了双隐层动态递归神经网络的数学模型，利用实验数据离线设计了神经网络辨识器与神经网络控制器。

By using an AD-like neurodegeneration mouse model, we show here that neurogenesis in the dentate gyrus was neurodegenerative stage-dependent.

通过研究类似AD神经退行性变小鼠模型，发现齿状回的神经发生与神经退行性变的阶段是呈依赖性的。

However, the same nerve stimulation caused a reverse in renal nerve discharge when the central sympathetic activity was inhibited by hyperventilation or unilateral depressor nerve stimulation.

相反，用过度通气或刺激一侧降压神经的方法使交感中枢活动水平降低时，同样的参数刺激排深神经，则使肾神经发放增加。

The CPT values in the affected leg in patient group were significant higher than those in control group at all frequencies. The CPT values in contralateral leg in patient group were significant higher than those in control group at 5Hz whereas there were no significant differences at 250Hz and 2000Hz. The CPT values in affected leg in patient group were significant higher than those in contralateral leg at 250Hz and 2000Hz whereas there were no significant differences at 5Hz. All the CPT values showed the same linear decrease from the dermatome of the compressed root to the dermatomes of the contralateral neighbor dematom.

在用CPT监测8例腰骶单神经根病组患侧和健侧及与正常对照组的不同直径感觉神经纤维功能的研究中发现压迫皮节和其临近皮节的所有频率CPT值无任何显著性差别；患者压迫侧的2000Hz及250HzCPT值及压迫侧和对侧的5HzCPT值与正常对照组都有显著性差别；患者组5HzCPT值患侧和对侧无差别，其他两组均有显著性差别；不管有无显著性差别，神经根病患者组各皮节三频率CPT值均按照压迫皮节，临近皮节，压迫对侧皮节，压迫对侧临近皮节的顺序减小，说明在腰骶单神经根病中Aβ纤维及Aδ纤维及无髓C纤维均受累。

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。
