Intussusception is rare in adults. We describe a 62-year-old man with jejunal ectopic pancreas that led to jejunojejunal intussusception and ileus. The patient was admitted to our hospital because of intermittent abdominal pain. Plain abdominal radiography showed some intestinal gas and fluid levels. Abdominal CT scan demonstrated a target sign suggesting bowel intussusception. Jejunography using a naso-jejunal tube showed an oval-shaped mass about 15 mm in diameter with a smooth surface in the jejunum, which suggested a submucosal tumor (SMT), and edematous mucosa around the mass. Partial jejunal resection was carried out and the resected oval-shaped tumor, 14 mm×11 mm in size, was found to be covered with normal jejunal mucosa. The tumor was histologically diagnosed as type ectopic pancreas according to the classification proposed by *** pain resolved *** case reminds us that jejunal ectopic pancreas should be included in the differential diagnosis of intussusception caused by an SMT in the intestine.

Possibility of the measurement of radiated waves derived from the thermally emitted electron Bernstein wave （EBW） is numerically investigated based on the assumption of the super dense core （SDC） plasma generated in LHD. EBW that is thermally emitted in the electron cyclotron resonance （ECR） layer may couple with the electromagnetic wave and be emitted to the vacuum via the EBW-extraordinary-ordinary （B-X-O） mode conversion process. We consider the use of one of the transmission lines for electron cyclotron heating （ECH） in LHD as a receiving system of the emission. It is derived that the waves in the fundamental cyclotron frequency range are emitted as the EBW near their upper hybrid resonance （UHR） layer outside the last close flux surface （LCFS）. On the other hand, waves in the second harmonics cyclotron frequency range are emitted in the core region. It means that successful measurement of waves of the second harmonic frequency range emitted from extremely high dense core plasma with setting an aim angle for receiving indicates a possibility of the second harmonic ECH by EBW in the core region with setting the same aim angle and the same polarization for launching.

这篇论文涉及半的一个班在奇怪的空间尺寸的线性夸张系统。我们的主要目的是证明 isasymptotic 的一个小振幅答案的存在，并且证明到免费答案，作为在精力标准的 t → - ∞，它有免费侧面著名计算机生产厂商→ + ∞。我们的途径基于工作[11 ] 。也就是，我们使用一个加权的 L~ ∞标准得到合适的先验的估计。这能被把我们的注意限制为放射状地对称的答案做。相应起始的价值问题也在一个类似的框架被考虑。而且，我们给扩大结果[14 ] 为三个空格在节 5 的维的大小写，它独立于纸的另外的部分被准备。

作为比亚迪丰田电动车科技有限公司第1款纯电动轿车,bZ3的能耗要求极高,也给空气动力学性能开发带来了很大的挑战。为实现这一目标,通过采用计算流体力学(Computational Fluid Dynamics,CFD)仿真和风洞试验相结合的方法,对车身造型、车底、前舱进气管理、车轮、密封等部位进行了持续的优化验证。最终bZ3在风洞中进行实车试验验收,空气阻力系数达到0.218,在同级别车型中处于领先水平。通过两种不同仿真方法对比研究发现格子玻尔兹曼(Lattice Boltzmann Method,LBM)方法整体精度较高,但对于底部气流的模拟精度还有待提升。

BACKGROUND Few studies compared the oncological and biological characteristics between ampullary carcinoma(AC) and cancer of the second portion of the duodenum(DC-Ⅱ), although both tumors arise from anatomically close *** To elucidate differences in clinicopathological characteristics, especially the patterns of lymph node metastasis(LNM), between AC and DC-Ⅱ.METHODS This was a retrospective cohort study of 80 patients with AC and 27 patients with DC-Ⅱ who underwent pancreaticoduodenectomy between January 1998 and December 2018 in two institutions. Clinicopathological factors, LNM patterns, and prognosis were compared between the two *** The patients with AC and DC-Ⅱ did not exhibit significant differences in 5-year overall survival(66.0% and 67.1%, respectively) and 5-year relapse-free survival(63.5% and 62.2%, respectively). Compared to the patients with DC-Ⅱ, the rate of preoperative biliary drainage was higher(P = 0.042) and the rates of digestive symptoms(P = 0.0158), ulcerative-type cancer(P < 0.0001), large tumor diameter(P < 0.0001), and advanced tumor stage(P = 0.0019) were lower in the patients with AC. The LNM rates were 27.5% and 40.7% in patients with AC and DC-Ⅱ,respectively, without significant difference(P = 0.23). The rates of LNM to hepatic nodes(N-He)and pyloric nodes(N-Py) were significantly higher in patients with DC-Ⅱ than in those with AC(metastasis to N-HE: 18.5% and 5% in patients with DC-Ⅱ and AC, respectively;P = 0.0432;metastasis to N-Py: 11.1% and 0% in patients with DC-Ⅱ and AC, respectively;P = 0.0186)CONCLUSION Although there were no significant differences in the prognosis and recurrence rates between the two groups, metastases to N-He and N-Py were more frequent in patients with DC-Ⅱ than in those with AC.
