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。

Flow activities inside the half stented aneurysm model were significantly diminished, specifically the pressures and wall shear stresses in the blob were decreased. It can be concluded that half bridged endovascular stents can promote intra-aneurysmal thrombus development and attenuate aneurysm rupture risk, and it is a feasible approach to treat aortic arch aneurysm.

仿真结果表明：半桥支架模型瘤腔内的流动受到明显抑制，特别是局部突起处的压力和壁面切应力大大地减小了，因此，半桥支架可以促进瘤腔内血栓的形成，并能减小动脉瘤破裂的危险，是一种可行的支架治疗动脉瘤的方法。

The objectives of the study were to construct a nonstented and a half stented aortic arch aneurysm models with blebs, demonstrate the detailed flow patterns, pressure and wall shear stress distributions around the aneurysm, and examine whether half stented aneurysms have preferable intra-aneurysmal hemodynamics for thrombus and occlusion.

为展示动脉瘤附近的详细流动情形和压力、壁面切应力分布，检验半桥支架是否具有可以促进瘤腔内血栓、闭锁形成的血流动力学特征，构建了无支架和半桥支架治疗带局部突起的主动脉弓动脉瘤模型。

Heart malformation, such as PTA, DORV, VSD and aortic arch malformation, were detected when neural crest were taken out before they migrated into 3, 4, 6 pharyngeal gland. Interestingly, the types of malformation were related with the length of neural crest destroyed; PTA was detected if the length exceeds two somites, while DORV would be detected if the length less than two somites. These results indicate that CNCCs are very important to the conotruncal development.

研究发现，如果在迁移之前切除散发到第3、4、6咽弓的神经嵴细胞，就会出现永存动脉干、主动脉骑跨、右室双出口、主动脉弓畸型和室间隔缺损等心血管畸形，且切除的长度与畸形的种类相关，如切除长度大于两个体节可产生永存动脉干，切除长度小于两个体节则产生右室双流出道，由此可见，心脏神经嵴细胞对于心脏圆锥部的发育意义重大。

Methods Marrow-derived mesenchymal stem cells were isolated and purified from mouse femoral bone and shinbones using differential adherent methods. Cells at the third passage were induced by 20% FBS in conditioned medium, conditioned medium alone, 20% FBS or 10% FBS alone respectively. Mouse aortic smooth muscle cells were cultured as the positive control. Levels of mRNA and protein expression of myoeardin and several smooth muscle cells marker genes were determined by immumofluorescenee, RT-PCR and Western blot before and 3, 7, 10, 14d after the induction. The presence of smooth muscle myofilaments was detected by using transmission electron microscope.

采用伞骨髓贴壁法分离骨髓问充质干细胞，CM联合20%FBS诱导骨髓间充质干细胞，同时设立持续10%FBS、单20%FBS及单CM诱导下的骨髓间充质十细胞对照组和SMC阳性对照组，分别于诱导前及诱导3、7、10和14 d时观察细胞形态的变化，并在相应的时间点用免疫荧光法、逆转录聚合酶链反应法、Western blot半定量分析法榆测myocardin以及SMC表面各种标志基因的表达变化，用透射电镜检测诱导后细胞内肌丝存在以此来证实诱导分化成功。

Methods Six patients underwent aortic reconstructions or partial aneurysm resections and one did hepatic cavernous hemangioma resection in general anesthesia. Cell saver was used for perioperative blood salvage and the washed blood was reinfused to all patients respectively during operation.

6例动脉瘤和1例肝血管瘤手术患者，在全身麻醉下行人造血管置换或动脉瘤部分切除术，在手术开始或体外循环结束时，启用全自动血液回收系统，回收术野的出血或渗血，进行浓缩、洗涤后，再回输入体内，并按回收-浓缩-洗涤-回输程序重复进行。
