| 2 | Numerical investigation on the flow and power of small-sized multi-bladed straight Darrieus wind turbine显示文摘Straight Darrieus wind turbine has attractive characteristics such as the ability to accept wind from random direction and easy installation and maintenance. But its aerodynamic performance is very complicated,especially for the existence of dynamic stall. How to get better aerodynamic performance arouses lots of interests in the design procedure of a straight Darrieus wind turbine. In this paper,mainly the effects of number of blades and tip speed ratio are discussed. Based on the numerical investigation,an assumed asymmetric straight Darrieus wind turbine is proposed to improve the averaged power coefficient. As to the numerical method,the flow around the turbine is simulated by solving the 2D unsteady Navier-Stokes equation combined with continuous equation. The time marching method on a body-fitted coordinate system based on MAC (Marker-and-Cell) method is used. O-type grid is generated for the whole calculation domain. The characteristics of tangential and normal force are discussed related with dynamic stall of the blade. Averaged power coefficient per period of rotating is calculated to evaluate the eligibility of the turbine. | JIANG Zhi-chao DOI Yasuaki ZHANG Shu-you | 2007 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2007，8，9： | 10 |

| 6 | Biochemically curative surgery for gastrinoma in multiple endocrine neoplasia type 1 patients显示文摘AIM: To search for the optimal surgery for gastrinoma and duodenopancreatic neuroendocrine tumors in patients with multiple endocrine neoplasia type 1. METHODS: Sixteen patients with genetically confirmed multiple endocrine neoplasia type 1 (MEN 1) and Zollinger-Ellison syndrome (ZES) underwent resection of both gastrinomas and duodenopancreatic neuroendocrine tumors (NETs) between 1991 and 2009. For localization of gastrinoma, selective arterial secretagogue injection test (SASI test) with secretin or calcium solution was performed as well as somatostatin receptor scintigraphy (SRS) and other imaging methods such as computed tomography (CT) or magnetic resonance imaging (MRI). The modus of surgery for gastrinoma has been changed over time, searching for the optimal surgery: pancreaticoduodenectomy (PD) was first performed guided by localization with the SAST test, then local resection of duodenal gastrinomas with dissection of regional lymph nodes (LR), and recently pancreas-preserving total duodenectomy (PPTD) has been performed for multiple duodenal gastrinomas. RESULTS: Among various types of preoperative localizing methods for gastrinoma, the SASI test was the most useful method. Imaging methods such as SRS or CT made it essentially impossible to differentiate functioning gastrinoma among various kinds of NETs. However, recent imaging methods including SRS or CT were useful for detecting both distant metastases and ectopic NETs; therefore they are indispensable for staging of NETs. Biochemical cure of gastrinoma was achieved in 14 of 16 patients (87.5%); that is, 100% in 3 patients who underwent PD, 100% in 6 patients who underwent LR (although in 2 patients (33.3%) second LR was performed for recurrence of duodenal gastrinoma), and 71.4% in 7 patients who underwent PPTD. Pancreatic NETs more than 1 cm in diameter were resected either by distal pancreatectomy or enucleations, and no hepatic metastases have developed postoperatively. Pathological study of the resected specimens revealed co-existence of pancreatic gastrinoma with duodenal gastrinoma in 2 of 16 patients (13%), and G cell hyperplasia and/or microgastrinoma in the duodenal Brunner's gland was revealed in all of 7 duodenal specimens after PPTD. CONCLUSION: Aggressive resection surgery based on accurate localization with the SASI test was useful for biochemical cure of gastrinoma in patients with MEN 1. | Masayuki Imamura Izumi Komoto Shuichi Ota Takuya Hiratsuka Shinji Kosugi Ryuichiro Doi Masaaki Awane Naoya Inoue | 2011 | World Journal of Gastroenterology2011，17，10： | 5 |

| 12 | Evaluation of prognostic factors and scoring system in colonic perforation显示文摘AIM: To study the significance of scoring systems assessing severity and prognostic factors in patients with colonic perforation. METHODS: A total of 26 patients (9 men, 17 women; mean age 72.7 ± 11.6 years) underwent emergency operation for colorectal perforation in our institution between 1993 and 2005. Several clinical factors were measured preoperatively and 24 h postoperatively. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), Mannheim peritonitis index (MPI) and peritonitis index of Altona (PIA Ⅱ) scores were calculated preoperatively. RESULTS: Overall postoperative mortality rate was 23.1% (6 patients). Compared with survivors, non- survivors displayed low blood pressure, low serum protein and high serum creatinine preoperatively, and low blood pressure, low white blood cell count, low pH, low PaO2/FiO2, and high serum creatinine postoperatively. APACHE Ⅱ score was significantly lower in survivors than in non-survivors (10.4 ± 3.84 vs 19.3 ± 2.87, P = 0.00003). Non-survivors tended to display high MPI score and low PIA Ⅱ score, but no signif icant difference was identif ied. CONCLUSION: Pre- and postoperative blood pressure and serum creatinine level appear related to prognosis of colonic perforation. APACHE Ⅱ score is most associated with prognosis and scores ≥ 20 are associated with signif icantly increased mortality rate. | Atsushi Horiuchi Yuji Watanabe Takashi Doi Kouichi Sato Syungo Yukumi Motohira Yoshida Yuji Yamamoto Hiroki Sugishita Kanji Kawachi | 2007 | World Journal of Gastroenterology2007，13，23： | 4 |
| 13 | Distinctive Precursory Air–Sea Signals between Regular and Super El Ni os显示文摘Statistically different precursory air–sea signals between a super and a regular El Ni no group are investigated, using observed SST and rainfall data, and oceanic and atmospheric reanalysis data. The El Ni no events during 1958–2008 are first separated into two groups: a super El Ni no group(S-group) and a regular El Ni no group(R-group). Composite analysis shows that a significantly larger SST anomaly(SSTA) tendency appears in S-group than in R-group during the onset phase[April–May(0)], when the positive SSTA is very small. A mixed-layer heat budget analysis indicates that the tendency difference arises primarily from the difference in zonal advective feedback and the associated zonal current anomaly(u).This is attributed to the difference in the thermocline depth anomaly(D) over the off-equatorial western Pacific prior to the onset phase, as revealed by three ocean assimilation products. Such a difference in D is caused by the difference in the wind stress curl anomaly in situ, which is mainly regulated by the anomalous SST and precipitation over the Maritime Continent and equatorial Pacific. | Lin CHEN Tim LI Swadhin K.BEHERA Takeshi DOI | 2016 | Advances in Atmospheric Sciences2016，33，8： | 3 |
| 14 | Oligomeric Procyanidins Induce Generation of Reactive Oxygen Species and Collapse of Mitochchondrial Membrane Potential in Glioblastoma Cell Lines显示文摘Objective The aim of the present study was to clarify the mechanism underlying glioma cell death upon oligomeric procyanidins (F2) exposure. Methods The cytotoxicity of F2 on U87 (human malignant glioblastoma cell line) and C6 (rat glioma cell line) cancer cells was evaluated, and changes of mitochondrial membrane potential (MMP) and production of reactive oxygen species (ROS) in drug-treated cells were monitored. Moreover, morphological changes associated with F2-induced cells death were examined. Results F2 induced a concentration-dependent increase in ROS production and decrease in MMP. Furthermore, pre-incubation with N-acetylcysteine (NAC) and rotenone (Rt), resulted in partial inhibition of F2-induced ROS generation and marked attenuation of cell death and the cytoplasmic vacuolization induced by F2. In addition, pretreatment with Rt markedly attenuated the MMP loss in F2-treated cells. However, pretreatment with NAC only markedly attenuated the MMP loss in F2-treated C6 cells. Conclusion The increase in ROS level is at least one of mechanisms associated with F2-induced glioma cell death as well as the cytoplasmic vacuolization formation that contribute to the cytotoxicity of F2 in glioma cells. | ZHANG Feng-jiao1, YANG Jing-yu1, MOU Yan-hua1, SUN Bao-shan2, WANG Ji-ming3, WANG Fang1, WU Chun-fu1 1.
