Methods The extracranial carotid arteries and proper palmar digital arteries of 80 patients with type 2 diabetic combine cerebral infarction, 30 patients with type 2 diabetic and 41 healthy collators were detected by colour-Doppler ultrasound ,the relationships between carotid IMT and risk factors of cerebrovascular disease were evaluated .

利用彩色多普勒超声对 80 例 2 型糖尿病性脑梗死患者、30 例单纯糖尿病患者及 41 例性别、年龄匹配的健康对照人群的颈动脉和指动脉进行检测，并分析颈动脉内中膜厚度与脑血管病危险因素间的关系。

The result reveals that the carotid gland is a crimson sphericity at the base of external carotid artery.

结果表明，颈动脉腺位于外颈动脉基部，圆球形，深红色至棕褐色。

Methods To observe the common carotid artery and its bifurcation, the internal carotid artery, external carotid artery intima-media thickness, plaque echo and hemodynamic changes.

方法观察颈总动脉及其分叉处、颈内动脉、颈外动脉内中膜厚度、斑块回声及血流动力学改变。

Methods: external jugular vein common carotid artery bypass graft model was established.

建立兔颈外静脉颈总动脉旁路移植模型，18只兔随机等分为3组，a：对照组，b：空载腺病毒液感染组，c： enos基因转染组。

Blank group was not given any treatment; in the sham-operation group, only rght common carotid artery was isolated and right external carotid artery was dissected without occlusion.

空白对照组不作任何处理；假手术组仅分离右侧颈总动脉并离断右颈外动脉，不予栓塞。

Methods A total of 125 cases including 40 hypertension patients without LVH, 45 hypertension patients with LVH and 40 control subjects underwent color Doppler ultrasonography. Intima-media thickness, plaque and hemodynamic indices were respectively measured in the common carotid artery and its bifurcation, internal carotid artery and external carotid artery.

对134例受检者进行颈动脉超声研究，其中高血压病非LVH 32例，高血压并LVH 62例，正常对照组40例，分别测量各组颈部动脉总干内中膜厚度、分叉内中膜厚度、斑块以及两侧颈总动脉、颈内动脉、椎动脉的血流动力学指标。

When conventional radiotherapy of nasopharyngeal carcinoma is practiced with the facio-neck field and inferior-neck-supraclavicular field by the half-beam technique, it is confirmed that the dose-overlap region at the match-plane is smaller than the whole-beam technique.

背景 近年来放射治疗剂量学研究表明，鼻咽癌应用面颈联合野与下颈切线野放射治疗时，与全束照射技术相比，半束照射技术的照射野衔接处剂量重叠区较小，理论上可能降低放射性神经损伤的发生率。

From the valve cover structure, according to different application requirements, can use regular valve cover, also can use the long-necked type valve cover, or with heat or heat-absorbing film of the long-necked type valve cover, in addition to Bellows seal valve cover.

从上阀盖结构看，根据不同应用要求，可采用普通阀盖，也可采用长颈型阀盖或带散热或吸热片的长颈型阀盖，另外还有波纹管密封型阀盖。

In addition to extending through the valve cover, so that the temperature packing medium temperature of the long neck away from the valve cap, the can increase heat or heat-absorbing film, made with heat, or heat-absorbing film of long-necked type valve cover to medium temperature is reduced or increased.

除了通过把阀盖延伸，使填料处温度远离介质工作温度的长颈型阀盖外，也可增加散热或吸热片，制成带散热或吸热片的长颈型阀盖，使介质温度得到降低或提高。

To the femoral neck fracture with neck-shaft angle of less than 135 degree, the fixation with the entry angle of less than 135° can make the neck-shaft angle rising, meanwhile, lag screw's location is easier to trend to the inferior of femoral head, displacement and angle between fracture surfaces satisfy the demand of functional reduction or extroversion reduction, and a satisfied stability is performed in biomechanical test.

对于颈干角小于135°的股骨颈骨折，以低于135 °的进钉角度固定时，能增大颈干角，同时拉力螺钉的位置更容易偏向股骨头颈的中、下部，骨折端的位移、成角也能够符合功能复位的要求，在力学测试中表现出较好的稳定性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
