objective to summarize 24 cases of preoperative observation and nursing of aortic dissection aneurysm.

目的 总结对24例主动脉夹层动脉瘤患者的术前观察与护理体会。

Myocardial ischemic model was made and hypotension in the dogs was induced with ligating left front descending limb coronary artery method, and secondary hypertension by narrowing nephridium artery of rats, Shenfu injection was administered with 5, 10mL·kg-1 to the above dogs and rats separately to investigate the influence of it on the hemodynamic indexes of myocardial ischemic dogs and blood pressure of rats.

结扎犬左冠状动脉前降支造成心肌缺血及低血压；缩窄大鼠腹主动脉造成血管阻力增加而形成继发性高血压；分别给予参附注射液5 ，10mL·kg-1，观察其对犬血流动力学和对动物正常血压或高血压的影响。

Methods Twenty-six NZW rabbits were randomly divided into three groups: a normal control group (fed on normal commercial rabbit diet, n =6), a hyperlipidemic group fed on high-fat ma total cholesterol (TC concentration at the beginning and the 12-week end point of the experiment determined,and all the experimental rabbits were sacrificed, and endothelial function test were performed on thoracic aortic rings prepared from the isolated aorta using the vascular endothelium-dependent relaxation parameter in response to acetylcholine The aortic atherosclerotic lesion expression of LOX-1 mRNA and protein were examined by RTPCR and Western blotting respectively.

方法新西兰大白兔随机分为正常对照组(普通饮食，6只)，高脂饮食组(高脂饮食，10只)及普罗布考组(高脂饮食+普罗布考200mg/kg·d，10只)。实验开始前及第12周分别耳缘静脉采血测定血清总胆固醇。第12周处死动物，取胸主动脉，制备离体胸主动脉环对乙酰胆碱的反应以检查内皮功能，RT-PCR与免疫印迹检测凝集素样氧化低密度脂蛋白受体-1(LOX-1)基因与蛋白质表达水平。

The following data were recorded: age, weight, preoperative pulmonary infiltrates, preoperative mechanical ventilation, evidence of increased PBF before surgery, duration of CPB, duration of aortic cross-clamp, duration of deep hypothermic circulatory arrest, use of steroids, and volume of ultrafiltrate removed.

同时记录下列数据：年龄，体重，术前肺浸润，术前机械通气及 PBF 增加的表现， CPB 时间，主动脉阻断时间，深低温停循环时间，类固醇使用和超滤液容量。

Dynamic respiratory compliance and total respiratory resistance were measured before surgical incision, after sternal closure in the operating room, and after arrival in the intensive care unit. The following data were recorded: age, weight, preoperative pulmonary infiltrates, preoperative mechanical ventilation, evidence of increased PBF before surgery, duration of CPB, duration of aortic cross-clamp, duration of deep hypothermic circulatory arrest, use of steroids, and volume of ultrafiltrate removed.

分别在麻醉诱导后、手术结束关胸后和返回ICU后3个时间点测定患儿的肺动态顺应性和全肺阻力，并记录患儿年龄，体重，术前胸片浸润性改变情况，术前机械通气情况，术前肺血流量增高情况，体外循环时间，主动脉阻闭时间，深低温停循环时间和体外循环中超滤量等参数。

These arise anterolaterally from the aorta almost immediately as it exits the aortic hiatus and extend over and supply the inferior surface of the diaphragm.

，主动脉几乎是一从主动脉裂孔出来，这两条动脉就从它的前外侧分支，向上行，为横隔膜下表面提供血液，它们还分别分支为多条身体同一侧的肾上腺上支动脉。

143 patients with sacrum tumor were divided into 6 groups according to different methods to control bleeding: non-vessel controlled in 21 cases, transcatheter arterial embolization before operation in 12 cases, hypogastric artery ligation in 71 cases ,temporary balloon occlusion of abdominal aorta in 9 cases, intermittent block of lower abdominal aorta in 5 cases, intermittent block of lower abdominal aorta and hypogastric artery ligation in 25 cases .

将143例骶骨肿瘤患者根据术中控制出血方法的不同分为6组，术前介入靶血管栓塞12例，髂内动脉结扎71例，球囊导管腹主动脉阻断9例，单纯低位腹主动脉阻断5例，低位腹主动脉阻断加髂内动脉结扎25例，未行控制出血的对照组21例。

Results Fifty-eight (93.5%) cases SVA were preoperatively discovered by echocardiography, while 2 (3.2%) misdiagnosed as tetralogy of Fallot and tricuspid regurgitation and 2 (3.2%) missed diagnosis.Accompanying teratisms included frequently ventricular septal defect (33 cases, 53.2 %) and aortic valve dysplasia(11 cases, 17.7%).The rupture site and the drainage chamber were essentially consisted with surgery,while the size of VSD measured by echocardiography was significantly smaller than that measured in operation.

结果 62例患者中，术前超声诊断Valsalva窦瘤破裂58例(符合率93.5%)，误诊为法洛四联症、三尖瓣反流各1例(3.2%)，漏诊2例(3.2%)；常见的合并畸形有干下室间隔缺损(33例，53.2%)、主动脉瓣发育不良伴重度主动脉瓣关闭不全(11例，17.7%)；超声报告窦瘤部位及破人腔室与手术结果一致，超声所测室间隔缺损大小明显低于手术所见。

Results A closure of the mitral and tricuspid valves with simultaneous opening of the aortic valve occurred exclusively during chest compression, resulting in forward blood flow in the pulmonary and systemic circulation. Peak forward aortic flow at a velocity of 58.8±11.6?cm/s was recorded during the compression phase.

结果 所有的6例病人，胸按压时，二尖瓣和三尖瓣关闭，同时主动脉瓣开放，前向血流自心室进入体循环和肺循环；发生在胸按压时的主动脉瓣峰值前向血流速度为58.8±11.6？

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。
