TBS had obvious image features on CDE:① The parasternal long axis view of two-dimensional echocardiography （2DE） image showed discontinuous echo of ventricular septal,and the anterior aorta developed from right ventricle while the posterior pulmonary artery straddled on the ventricular septal, which was named 2DE ＂straddle sign＂.

TBS的CDE图像特征：①二维超声心动图（2DE）胸骨旁左室长轴观显示室间隔回声中断，主动脉在前方发自右心室，肺动脉在后方骑跨在室间隔之上，称2DE&骑跨征&。

Distant metastases to the lungs (n=4), pleura (n=2), brain (n=3), and peritoneum (n=1), and paraaortic, paratracheal, and mediastinal LNs (n=2) were observed. Six of 9 patients (66%) died from tumor dissemination, all with a median overall survival of 4.3 years (range: 1 to 9 y).

此外，远处转移情况如下：肺（4例），胸膜（2例），脑（3例），腹膜（1例），主动脉旁、气管旁和纵膈淋巴结（2例）。6例（66%）死于肿瘤播散，其总体中位生存时间为4.3年（范围：1至9年）。

Surgical procedures included eight proximal pancreatectomies, three total pancreatectomies, nine distal pancreatectomies, and three tumor enucleations from the pancreatic head. Three patients had superior mesenteric vein reconstruction, six had liver resection, one had an extended periaortic node dissection, 11 had splenectomy, and one had left nephrectomy.

手术的过程包括8个近端的胰脏切除，三个全胰脏切除，九个末梢的胰脏切除，和三个进行肿瘤切除，三个患者有较佳的中肠静脉重建术，六名进行肝脏再切除，一名患者有广泛的进大主动脉节切除，1人进行脾脏切除，一名患者进行左肾切除术。

The expression of FOXC2 could be seen in cordis great vessels, endocardium, chondrocyte and periost of axial skeleton during pregnant 70 days, and only in primary ossification center of axial skeleton and coronary artery during pregnant 80 day.

孕50天后表达于背主动脉、弓形动脉和原始心脏内膜、锥体雏形细胞；孕70天时，在心脏大血管、心内膜和中轴骨骼的软骨细胞和骨膜细胞表达；孕80天时仅表达于中轴骨骼的骨化中心和冠状动脉。

The first abdominal branches of the aorta are the paired inferior phrenic arteries html.

We previously reported that unclamping of an abdominal aorticcross-clamp causes initial dilation of pial arteries followedby sustained constriction.

以前我们曾报导了腹主动脉阻断钳松夹可引起软脑膜内动脉先扩张随后持续收缩。

Results The values of some serum biochemical parameters obtained from samples taken from different sites differed significantly. The values of TP and ALB of blood taken from abdomial aorta or external jugular vein were significantly higher than those of blood taken from postcaval vein in the rats. The values of several parameters of the blood taken from orbital vein differed significantly from those from femoral vein blood samples.

结果腹主动脉及颈外静脉均与后腔静脉血液生化值在总蛋白、白蛋白上存在明显差异，表现为前者血清中总蛋白、白蛋白明显高于后者；大鼠眶静脉与股静脉血液生化值在多项指标上亦存在明显区别。

Uterine obstruction of venous return can produce prearrest hypotension or shock and in the critically ill patient may precipitate arrest.1,2In cardiac arrest the compromise in venous return and cardiac output by the gravid uterus limits the effectiveness of chest compressions.

在怀孕20周以后，妊娠子宫挤压下腔静脉和主动脉，使静脉回流和心输出量受阻。子宫静脉回流受阻会导致停跳前高血压或休克，对病情危重的患者促进心跳停止[1，2]，同时，妊娠子宫还限制肺的舒张。
