METHODS AND RESULTS: 1763 participants (829 M and 934 F; 38 to 88 years of age) of the Framingham Heart Study Offspring cohort underwent CMR of the thoracoabdominal aorta using an ECG-gated 2D T2-weighted black-blood sequence.

方法和结果：参加弗明翰研究的1763人（829名男性和934名女性，年龄38－88岁）通过心电图门控的2维T2加权的黑血扫描序列进行胸腹主动脉CMR扫描。

Methods A total of 36 patients with advanced renal cancer were definitely diagnosed by IVP, US, CT or MRI examination. A 5F Yashiro catheter was introduced into the femoral artery with Seldinger's technique under local anesthesia, abdominal aortagraphy and renal arteriography in both sides of kidneys were performed routinely to display the blood supplying arteries of tumor, thereafter, renal embolization was performed under superselective catherization for chemotherapeutic embolizing. Then the clinical effect was observed, the amount of blood loss and the operation time were recorded. All these results were compared with that of randomly selected 17 patients before surgical operation with advanced renal cancer admitted during the recent 3 years but without embolization.

36例中晚期肾癌患者，均经临床检查、静脉肾盂造影、B超、CT或MRI检查而确诊；采用Seldinger's技术，局部麻醉下经一侧股动脉穿刺插管，引入5F Yashiro导管，常规行腹主动脉及双肾动脉造影，以显示肿瘤的供血动脉，再将导管超选择插管或尽可能接近肿瘤病灶，进行化疗栓塞，观察其临床改善情况，计算术中失血量及手术时间，并与随机抽取我院近3年所做的17例术前未行肿瘤供血动脉栓塞的肾癌患者进行对照。

Objectives The purpose of this study was to evaluate the effect and mechanism of As〓O〓-gelatin-coating stents on rabbits'aortas and smooth muscle cells.

目的 研究氧化砷-明胶涂层的超弹性NiTi支架对兔主动脉组织及平滑肌细胞的作用，旨在探讨氧化砷预防支架内再狭窄的机制。

Compared to control, wild type apo A-I gene transfer led to about a 25 percent decrease in the amount of plaque buildup in the animals' aortas and other vessels.

与对照组比较，野生型脂蛋白-我的基因转移，导致约25 ％的款额减少菌斑积聚在动物的主动脉及其它船只。

Acclimatization 1.73±1.82** 0.61±0.06 0.98** P＜0.01 vs normoxic rats.After the aorta preparations were precontracted with NE at the concentration of 0.62 μmol/L, a ccumulative vasodilative effects of ACh were tested.

与常氧对照组相比，急性低氧和间断低氧习服后，大鼠主动脉对ACh各浓度(10- 9～10-5 mol/L)引起的舒张反应显著减弱(P＜0.01)，其最大舒张分别为常氧对照组的87.3％和79.7％，其EC50值分别为1.34和1.73 μmol/L，分别为常氧对照组EC50值0.20 μmol/L的6.7和8.6倍(表2)。

Objective To investigate the changes of endogenous nitric oxide and carbon monoxide in atherosclerosis induced by high cholesterol diet in rabbits and influence of NO and CO on the atherosclerotic process.

目的 探讨主动脉内源性一氧化氮及一氧化碳在高胆固醇饮食诱导的动脉粥样硬化中的变化及对AS进程的影响。

Nonetheless, it poses a risk of rupture and mortality equal to the aneurismal form.

然而，它和以动脉瘤表现的主动脉炎有同样高的破裂和死亡的机率。

Results The cells were remeved effectively from cusps and roots of porcine aortic valves by Triton X-100 and sodium dedecyl sulfate in 96 h.

TritonX-100较好的保持了主动脉瓣胶原纤维和弹性纤维的原有排列和分布，并有较好的力学性能。

In the SMC of the normal rabbits, myofilaments and macula densa were abundant, few mitochondrla and endoplasmic reticulums were found around the nuclear, and the SMC was in the contractive stage. In the SMC of the model rabbits, few myofilaments and macula densa were found, rough surfaced endoplasmic reticulums and mitochondria were abundant, some phagocytosed much lipid and became foam cells, the SMC was in the synthetic stage.

实验12周，高脂组家兔主动脉斑块面积百分比为47.69±12.84％，内膜斑块厚度为0.68±0.08mm，内膜斑块横断面积与中膜面积比值为1.28±0.35；内膜脂质斑块弥漫且较厚，有大量的泡沫细胞堆积，可达8～10层，管腔直径变小，内膜不光滑；泡沫细胞内富含脂滴，呈椭圆形气球样，有的斑块中可见显著的平滑肌细胞增生及大量的弹力纤维形成。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
