颈动脉

CTA may prove useful in detection of carotid artery stenosis and occlusion, and provide information about calcific plague, ulceration for carotid endarterectomy.

采用电子束CT和三维工作站可清晰显示颈动脉的解剖和异常，为颈动脉内膜剥脱术提供可靠的影像学依据。

The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

Carotid homodynamic can be as of reliable index to evaluate carotid arteriosclerosis in cerebral infarction patients.

颈动脉血流动力学指标可以作为评价脑梗死患者颈动脉粥样硬化程度的可靠指标之一。

Age, gender, hypertension, high lipohemia had significant relationship with carotid artery stenosis.

颈动脉狭窄造成的眼部供血下降可以导致多种眼缺血性疾病，通过对颈动脉狭窄的正确诊断和治疗可以迅速缓解眼部的病情。

Methods 100 cases were randomized into treatment group in which 50 cases were treated with Safflower injection via carotid artery infusion, added Safflower injection 20ml into 0.9% sodium chloride injection 60ml with the 4ml/min velocity, once a day; control group in which 50 cases were treated with venous drip of Safflower injection, added Safflower injection 20ml into 0.9% sodium chloride injection 500ml. After therapy, the curative effect、 myodynamia and hemorrheology were compared between the two groups.

将100例脑梗死患者随机分为红花注射液颈动脉灌注组50例和红花注射液静脉滴注组50例，治疗组：于0.9%氯化钠注射液60ml中加入红花注射液20ml，以4ml/min的滴速经颈动脉灌注；对照组：以红花注射液20ml加入0.9%氯化钠注射液500ml中静滴，20天后对两组疗效进行分析并观察治疗前后肢体肌力及血液流变学变化。

Like MRA, CTA is useful when carotid duplex is ambiguous, permitting isualization of aortic arch or high bifurcation pathology, reliable differentiation of total and subtotal occlusion, assessment of ostial and tandem

CTA能够使主动脉弓和高位颈动脉分叉显影，可靠区分全部和部分血管闭塞，评估开口和串联性狭窄，而且能够对心律不齐，瓣膜性心脏病，心肌病患者的颈动脉疾病进行评价。

While carotid endarterectomy is performed in the emergency setting of an acute ischemic stroke that occurs postcarotid endarterectomy, emergency carotid endarterectomy is not generally done because there are concerns for complications of brain edema and hemorrhagic transformation due to reopening of the vessel and reperfusion of the stroke area.

很少有 &有效性的手术治疗急性缺血性中风的信息&虽然颈动脉内膜切除术是在急性缺血性中风发生 postcarotid 剥脱的紧急情况制定的，但紧急颈动脉内膜切除术一般不这样做，因为人们担心由于血管再通和缺血区域再灌注而致脑水肿和出血的并发症。

Carotid sinus is located in the lateral mid-point of the neck, carotid artery pulsatility most obvious place.

颈动脉窦位于颈部外侧中点，颈动脉搏动最明显的地方。

The expression of AT2R gene can be regulated efficiently in vivo by local delivery of MSC with dual-stable expression of AT2R gene, thus reduces the formation of intimal hyperplasia.④AT2R gene can influence the expression of ECM and significantly promote the cellular apoptosis in the injury rat carotid artery.⑤These data demonstrate the clinical potential of AT2R regulatable expression to prevent restenosis after PCI.

研究结论：(1)与VSMC直接接触可以诱导MSC向血管成分细胞分化；(2)构建的Dox-on可调控的MSC细胞株诱导活性可靠，使外源AT2R基因的表达处于有效的主动控制下；(3)局部导入MSC不影响球囊损伤后大鼠颈动脉新生内膜增生；(4)由MSC介导的AT2R可调控表达受到Dox的良好调控，可有效抑制球囊损伤后大鼠颈动脉新生内膜增生；(5)AT2R影响血管损伤后修复时ECM成分的表达，并促进细胞凋亡的发生，可能是AT2R介导抑制新生内膜形成的机制。

Methods (1) Through microsurgical direct destruction of the arterial intima and internal elastic lamina at the bifurcation of the carotid artery in 30 rats,saccular aneurysms can be induced immediately, and the contralateral carotid arterys were ligated in half of t...

(1)通过显微手术方法直接破坏大鼠颈动脉分叉部位的内膜和内弹力层，建立大鼠实验性囊性动脉瘤模型，并在结扎及未结扎对侧颈总动脉的情况下，观察4-5个月。

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％。
