The symptoms of aortic stenosis may resemble other medical conditions or heart problems.

主动脉狭窄的症状可能类似于其他的疾病或心脏问题。

Congenital aortic stenosis occurs in 3 to 6 percent of all children with congenital heart disease.

先天性主动脉狭窄的发病率占所有先天性心脏病患儿的3－6％。

Methods Three recombinant retroviral expressive vecto rs, aMl, aM2 and aM3, which respectively loading reverse fragment of exon 1,2 and 3, were transferred in to rat arterious SMC and assayed 1 month after their stable expression.

分别载有c-myc 第1、2 和3外显子反义片段的3种重组逆转录病毒表达载体 aM1、aM2 和 aM3 被导入体外培养的大鼠主动脉平滑肌细胞，并于持续筛选后1个月进行稳定表达检测。

RESULTS ①After HE staining, obvious atheromatous plaque has been formed in the experimental group, but there is no histopathology changes in the control group.

结果 ①经苏木精-伊红染色，显微镜下观察可见模型组大鼠的主动脉有明显的粥样斑块形成，对照组未见明显变化。

These data suggest that arotic arch and arch of azygos vein are the key structures to identify the superior aortic recess and lymph nodes. They are essential for understanding the related pathologic changes depicted on CT and MR images.

主动脉弓和奇静脉弓是识别主动脉上隐窝、淋巴结等结构的重要标志，它们在CT和MRI影像学上具有重要的意义。

104 Cases of calcific aortic disease were found by the ultrasonic images in 2490 elderly cadres.

本文分析了在2490名中老年干部中经超声心动图诊断的104例钙化性主动脉瓣病的超声心动图表现。

Prof. Shelton: Well it's a very important topic and we are seeing calcific aortic stenosis of the elderly more frequently these days I believe than we used to because people are living longer to have the disease.

Shelton教授：这个话题非常重要，我们现在看到比从前更多的老年患者出现主动脉钙化狭窄，我想这是因为人的寿命比以前更长了。

Atherosclerotic/calcific aortic stenosis, on the other hand, develops at later in life and is a manifestation of diffuse atherosclerosis that commonly affects elderly individuals.

另一方面，动脉粥样硬化/钙化性主动脉瓣狭窄出现的时期更晚，表现为广泛的动脉粥样硬化，常好发于老年人。

Objective:To observe the feasibility and efficiency of intra-aortic balloon pump implantation,guided by Echocardiographly in patients with cardiogenic shock.

目的：探讨床旁超声引导下主动脉内气囊反搏植入术的可行性及对心源性休克的疗效。

Results: B-type ultra-sonic graph showed abnormal blood vessels in hepatic hila. CT or DSA demonstrated intra- and extra-hepatic abnormal ectatic arteries, intrahepatic telangiectasia, cirrhosis and hepatic enlargement.

强化CT及血管成像显示3例患者腹主动脉周围、肝门区及肝内迂曲扩张的动脉血管、肝内弥漫扩张的毛细血管网和肝硬化，2例年轻患者肝脏体积增大。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
