典型的胸部X光异常可以帮助我们在鉴别诊断上需要将主动脉炎和食道破裂纳入考虑，紧急的胸部电脑断层是区分这些病灶的最好工具并且进一步快速诊断罕见合并沙门氏杆菌感染的主动脉炎和脓胸。

Methods and results Using high-resolution ultrasound system, we measured the diameter of the brachial arteries at rest, during reactve hypermia and after sublingual glyceryl trinitrate (GTN, 400μg) in 58 subjects, consisted of 18 controls with normal blood presure, and 40 patients with EH.

He recalls a mother in her late 20s who came to him because she had an inoperable defect in her aorta that would rupture at some undeterminable time in the future, killing her instantly.

他提起这样一位母亲：将近30岁的她来求助，因为在她的一条主动脉上存在着某种缺陷（inoperable defect 。译者很迷茫），所以主动脉会在将来的某个不确定的时间爆裂，这会使得她当场死亡。

Posteriorly, the middle sacral artery arises from the terminal aorta just above its bifurcation into the common iliac arteries and extends caudally on the anterior surface of the fifth lumbar vertebra and sacrum.

主动脉最后的分支是从它末端分出来的骶正中动脉，分支点就在主动脉杈分支为髂总动脉的上面，骶正中动脉从第五腰椎和骶骨的前面向尾部延伸。

Single proton emission computer tomography and X-Ray film were taken to observe the allocation of the drugs.Results (1) Pelvic and periaortic nodal 5-FU concentrations of RP were 60～106 and 76～119 times of that of IP respectively.(2) The nodal 5-FU concentrations on repeated injection side were 16～20 times of that on control sides of RP.(3) There was no complications or adverse effect observed.(4) 5-FU was allocated to the space including the external iliac, internal iliac, obturator, deep inguinal and common iliac lymph nodes and also up to the periaortic lymph nodes.

结果 (1)腹主动脉旁淋巴结5-FU浓度，腹膜后化疗是腹腔化疗的76～119倍；盆腔淋巴结5-FU的浓度，腹膜后化疗是腹腔化疗的66～106倍；(2)腹膜后化疗重复注药，注药侧5-FU浓度为未注药侧的16～20倍；(3)腹膜后化疗与腹腔化疗均无明显的毒副作用；(4)经盆腔腹膜外间隙给药，药物能从盆腔上行至腹主动脉旁淋巴结及其周围。

The aorta lies just to the left of the midline atop the lumbar vertebrae, ending at approximately the lower portion of the fourth lumbar vertebral body, where it bifurcates into the two common iliac arteries.

在腰椎体的上面主动脉就位于中线的左侧，主动脉约在第四腰椎体的下部终止，分支为两条髂总动脉。

Methods:All the 40 Winstar rats were divided into four groups:group A:the rats were fed with normal diet,group B:the rats were fed with only high|cholesterol diet(no vitamin D3),group C:the rats were treated with one intramuscularly injection of vitamin D3(300 000 U/kg) and were denudated of endothelium,followed by high|cholesterol diet,group D:the rats were treated with 5% chitosan added into the diet besides treatment as group C.Ninety days later,the formation of atherosclerosis plaques and the activities of nitric oxide synthase in aortas in the four group rats were investigated.

40只Wistar大鼠均分为：A组；B组：饲以高脂饲料（不含维生素D3）；C组：一次性给予大鼠维生素D3（30万U/kg体重）肌肉注射，以球囊损伤主动脉内皮和饲以含维生素D3（1.25×106U/kg）的高脂饲料；D组在C组的基础上饲料中加入5%壳聚糖。90 d后检测主动脉动脉粥样硬化斑块形成及NOS的活性。

These include: the pre-VAD insertion examination of the heart and largevessels to exclude significant aortic regurgitation, tricuspidregurgitation, mitral stenosis, patent foramen ovale, or othercardiac abnormality that could lead to right-to-left shunt afterleft VAD placement, intracardiac thrombi, ventricular scars,pulmonic regurgitation, pulmonary hypertension, pulmonary embolism,and atherosclerotic disease in the ascending aorta; and to assessright ventricular function; and the post-VAD insertion examinationof the device and reassessment of the heart and large vessels.

这些包括：（1） VAD 植入前心脏和大血管的检查以排除明显的主动脉反流、三尖瓣反流、二尖瓣狭窄、卵圆孔未闭或者可能引起左 VAD 植入后右向左分流的其他心脏异常，心内血栓、心室疤痕、肺动脉反流、肺动脉高压、肺栓塞和升主动脉粥样硬化疾病；并且评估右室功能；（2） VAD 植入后检查设备及再评估心脏和大血管。

Which are this: my mother, who is not quite 85, has aortic stenosis, a narrowing of the heart's aortic valve, and her cardiologist has just told her that it's time now to think about open-heart surgery to replace the valve.

正是这一点：我的母亲，还不到85 岁，患有主动脉瓣狭窄，缩小心脏的主动脉瓣，她的心脏病就意味着，是时候做心内直视手术了以取代阀门。

Over the years, I have taken dozens and dozens of elderly patients with aortic stenosis through aortic valve surgery usually with very good outcomes.

多年来，在我这就诊的有很多主动脉瓣狭窄的老年患者，他们行主动脉瓣置换术后的结果也很好。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
