The present results suggest that (1) NA is not mainly concerned with spontaneous discharges of chemoreceptor sensitive to hypoxia, but does elicit an increase in spontaneous discharges, and (2) the increase of chemosensory unit discharges produced by hypoxia can be inhibited by yohimbine.

结果提示：(1)NA不是维持颈动脉体对缺氧敏感的化学感受纤维自发放电活动的主要因素，但给予NA能增加此类纤维自发放电的频率；(2)在低氧过程中，给予#alpha#_(2)受体拮抗剂育亨宾，可减弱这类纤维对缺氧反应的程度。

Stent should be soft, with good lateral bending property, and diameter of the stent should be 1.0-2.0 mm longer than the actual stenosis. Implantation technique should be improved. These can reduce extrusion and cutting action of the atheromatous plaque due to balloon dilatation and stent expansion, and prevent plaque defluxion during implantation. Filter protection device is used to filter tissue debris and to prevent microemboli entering cerebral circulation, which can elevate safety of carotid stent implantation.

选择相对柔软的，侧弯性能较好，且直径应比狭窄处实测直径大1.0~ 2.0 mm的支架，提高置入操作技术，可以减轻支架置入过程中球囊扩张及支架膨胀时对粥样斑块的挤压与切割作用，防止斑块脱落，同时使用滤器脑保护装置以过滤较大组织碎片，阻止较大微栓子进入脑循环，提高颈动脉支架置入的安全性。

These relative risks did not change significantly after adjustment for age; sex; total cholesterol, low-density lipoprotein cholesterol, or triglyceride levels; carotid-wall thickness; smoking status; the presence or absence of diabetes and systolic and diastolic hypertension; body mass index; and other risk factors. In women, Lp lipoprotein levels were not related to cardiovascular risk, even after adjustment for estrogen use or nonuse.

这些相对危险性经过年龄、性别、总胆固醇、低密度脂蛋白胆固醇、或三酸甘油酯浓度、颈动脉管壁厚度、吸烟状态、糖尿病和心脏收缩及舒张高血压的有无、身体质量指数、和其他的危险因子的调整后并没有显著改变，而在女性方面，Lp脂蛋白浓度与心血管风险无关，即使经过雌激素有无使用的调整后也是如此。

To make matters worse, the companies said in November that they planned to rejigger the analysis to focus on an ultrasound measurement at only one point of the carotid artery, as opposed to three points, as originally stated in the study's plan.

两家公司在今年11月的一项决定将事情弄的更糟，它们准备对原先的分析方法进行修改即只对颈动脉一点进行超声测量而不是原先的对三点进行超声测量。

She said he was undergoing tests but gave no further details about his condition. Mr. Kennedy, who is 76, had preventive surgery in Boston in October to unclog a partially blocked carotid neck artery.

她表示肯尼迪目前正接受检查，但对他的情况并没有进一步详细说明。76岁的肯尼迪去年十月在波士顿接受清除颈动脉阻塞的预防性手术。

METHODS: As a pilot study, we prospectively evaluated 30 consecutive patients who underwent anterior cervical diskectomy and fusion to assess the interobserver accuracy of palpating the mandibular angle, hyoid, carotid tubercle, and thyroid and cricoid cartilages.

作为先导研究，我们前瞩性的评估连续30例行椎间盘切除并融合术的病人，评价触摸下颌角、舌骨、颈动脉结节、甲状软骨和环状软骨时目标观察物的准确度。

Major sources of heterogeneity were age distribution, carotid segment definition, and IMT measurement protocol.

来源资料的不均一性主要是年龄分布、颈动脉段的确定和IMT的测量标准。

In the rat carotid injury model, SM16 dosed once daily orally at 15 or 30 mg/kg SM16 for 14 days caused significant inhibition of neointimal thickening and lumenal narrowing. SM16 also prevented induction of adventitial smooth muscle alpha-actin-positive myofibroblasts and the production of intimal collagen, but did not decrease the percentage of proliferative cells.

在大鼠颈动脉损伤模型中，每日口服15或30mg/kgSM16持续14天能够显著抑制新生内膜增厚及管腔狭窄，预防对外膜α-SMA阳性肌成纤维细胞的诱导和内膜胶原的合成，但并不降低增殖细胞的比例。

The rest was recovery. Conclusion:Early diagnosis, effective haemostasis and reconstruction of carotid artery are the keys to reduce the mortality and decrease the morbidity of neurological deficit.

早期诊断，及时有效的止血，修复血管，尽快恢复颈动脉血流和必要的脑保护措施是降低病死率，减少神经系统并发症的关键。

随着保护技术的应用和防止再狭窄技术的成熟，介入治疗将在颈动脉狭窄治疗中发挥更大的作用。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
