Methods Fifteen dogs were randomly divided into 3 groups. Group A acted as the control group without CPB; group B and group C were subjected to cardiopulmonary bypass and crossclamping the aorta for 90 min. MP or saline was injected intravenously before surgery. Plasma levels of IL-1β、TNF-α、IL-6、IL-8 and IL-10 were measured at the following time points: before MP or saline were administered, aortic declamping, 30 min and 90 min, after aortic declamping. Immediately after the animals was killed, pulmonary arterial rings were obtained and mounted in organ chamber for assessment of endothelial function with endothelium-dependent or non-endothelium-dependent studies.
健康家犬15只，随机分为3组，A组：不进行CPB，作为非体外对照组；B组：麻醉后注射生理盐水10mL，常规全麻和CPB，主动脉阻断90min；C组：麻醉后静脉给予甲泼尼龙5mg/kg，其余处理同B组。B、C组分别在手术前及主动脉开放前、开放后30min和90min 4个时间点采动脉血，放免法测定血浆白介素－1β(IL-1β)、肿瘤坏死因子－α、白介素－6(IL-6)、白介素－8(IL-8)和白介素－10(IL-10)水平；手术结束时，A、B、C 3组均取右肺动脉段，固定于张力传感器，测定血管环内皮依赖性和非内皮依赖性扩张能力的变化。

In the current study it is difficult to be certain that the decreased aortic distensibility in aortic dissection were due to structural changes of the aortic wall, or simply reflected dilated aortic dimension and aortic valve regurgitation. Further study is necessary to elucidate the underlying mechanisms for this abnormalities.
本研究用无创的超声技术证明主动脉夹层之升主动脉扩张性明显降低，这对主动脉夹层病因学的进一步深入研究无疑具有重要意义；但其降低是由于血管本身结构异常所致还是继发于血管内径的扩张尚有待进一步深入研究。

Considering the underlying wall deficiency and the homodynamic stress, the Robiesek operation should be an optimal choice to those patients with a mild to moderate dilated ascending aorta caused by aortic valve lesion.
由于主动脉壁本身存在病理改变和血液动力学冲击，为防止远期升主动脉进一步瘤变或夹层形成，对以主动脉瓣病变为主的轻、中度主动脉根部扩张采用Robicsek术更为合理。

For example, doctors use accurate measurements of the aorta to help determine the rate at which the aorta is dilating.
举例来说，医生使用精确测量的主动脉，以帮助确定利率，即是主动脉扩张。

To study the changes in diameter of dilated ascending aorta following aortic valve replacement.

Methods: From December 2002 to June 2006, 30 patients with a moderately dilated ascending aorta [mean diameter,(46.7±3.1)mm] underwent concomitant aortic valve replacement or repairing and reinforced aortoplasty with a well-tailored Dacron vascular graft. Follow-up was obtained on all patients with ultrasonic cardiography or computed tomography scan and was (18.0±10.5) months.
对2002年10月至2006年6月间采用主动脉置换或成形、升主动脉缩小成形、升主和根部背心式人工血管包裹术治疗的30例主动脉瓣病变和升主动脉扩张的临床病例进行回顾性分析和随访，平均随访时间(18±10.5)个月。

And rheumatic valves also accounted for 70 cases (88.5%) of aortic stenosis plus insufficiency. The rheumatic valves was decreased dramatically as the cause of the aortic valve disease, aortic root dilation and degenerative valves increased significantly, while others had no significant changes.
随着社会进步和人口老龄化，风湿性病因所占比例大幅下降，主动脉根部扩张导致的主动脉关闭不全有较大幅度的上升，退行性主动脉瓣有所上升，二叶式主动脉瓣、感染性心内膜炎所致瓣膜损害变化不明显。
-
The causes of acrtic valve diseases in the three groups were analyzed. Results: Rheumatism was the most common reason, accounting for 59.7%(43 cases) of simple aortic stenosis, while bicuspid valves accounted for 23.6%(17 cases). The most common cause for aortic insufficiency was root dilation (38 patients, 43.2%).
结果：风湿性、二叶式主动脉瓣、主动脉根部扩张以及退行性主动脉瓣病变是主要的病因类型，其中单纯主动脉瓣狭窄以风湿性（43例，占59.7%）及二叶瓣17例(23.6%)病因为主，单纯主动脉瓣关闭不全以根部扩张（38例，占43.2%）为主，主动脉瓣狭窄合并关闭不全则以风湿性（70例，占88.5%）为主。

Aortic dissection：主动脉夹层分离
主动脉夹层分离(aortic dissection)指主动脉腔内的血液通过内膜的破口进入主动脉壁中层而形成的血肿,并非主动脉壁的扩张,有别于主动脉瘤,过去此种情况被称为主动脉夹层动脉瘤(aortic dissecting aneurysm),现多改称为主动脉夹层血肿(aortic dissectin ghematoma),
-
aortic insufficiency：主动脉瓣关闭不全
主动脉瓣关闭不全(aortic insufficiency)主要由主动脉瓣疾病引起,可以是风湿性主动脉瓣炎,也可以是感染性心内膜炎及主动脉粥样硬化和梅毒性主动脉炎累及主动脉瓣,病变致使瓣膜增厚、变硬、缩短、弹性减弱或消失,引起瓣膜环扩张,致使主动脉瓣关闭不全.
