2Submucosal tunneling and endoscopic resection of submucosal tumors at the esophagogastric junction显示文摘AIM: To evaluate the safety and efficacy of submucosal tunneling and endoscopic resection(STER) for treating submucosal tumors(SMTs).METHODS: Between August 2012 and October 2013, 21 patients with SMTs originating from the muscularis propria(MP) layer at the esophagogastric junction were treated by STER of their tumors. Key steps of the procedure include:(1) mucosal incision: a 2-cm longitudinal mucosal incision was made 5 cm proximal to the tumor;(2) submucosal tunneling: a submucosal tunnel was created 5 cm proximal to and 1 to 2 cm distal to the tumor;(3) tumor resection: the SMT was resected under direct endoscopic viewing;(4) hemostasis: while finishing the tumor resection, careful hemostasis of the MP defect and the tunnel was performed; and(5) mucosal closure: the mucosal incision site was closed by using hemostatic clips. During the operation, equipment used included a cap-fitted endoscope, an insulatedtip knife, a hook knife, hemostatic forceps, an injection needle, a snare, an endoclip, and a high-frequency generator. Carbon dioxide(CO2) insufflation was achieved by using a CO2 insufflator.RESULTS: The median age of the patients was 46.2 years(range, 35-59 years), and the majority were male(18 male vs 3 female). Complete resection rate was 100%(21/21). Eighteen lesions were resected en bloc. Mean tumor size was 23 mm(range, 10-40 mm), and mean procedure time was 62.9 min(range, 45-90 min). Pathological diagnosis of these tumors included leiomyoma(15 out of 21) and gastrointestinal stromal tumor(6 out of 21). Full-thickness MP resection was performed in 9 of 21 patients(42.9%), with mediastinal and subcutaneous emphysema occurring in all nine. At the completion of the procedure, all patients received closure of the incision with hemoclips. One patient required percutaneous drainage. The remaining 20patients required no further endoscopic or surgical intervention. There were no incidents of massive or delayed bleeding. The median follow-up period after the procedure was 6 mo(range, 2-14 mo). During followup, no patients were found to have residual or recurrent tumor or esophageal stricture.CONCLUSION: STER is safe, effective and feasible, which provides accurate histopathologic evaluation and curative treatment for SMTs originating from the MP layer at the esophagogastric junction.De-Jun Zhou Zhen-Bo Dai Malcolm M Wells Dan-Lei Yu Jing Zhang Lei Zhang 2015World Journal of Gastroenterology2015,21,2:20
3Community analysis of ammonia-oxidizing bacteria in activated sludge of eight wastewater treatment systems显示文摘We investigated the communities of ammonia-oxidizing bacteria(AOB) in activated sludge collected from eight wastewater treatment systems using polymerase chain reaction(PCR) followed by terminal restriction fragment length polymorphism(T-RFLP),cloning,and sequencing of the α-subunit of the ammonia monooxygenase gene(amoA).The T-RFLP fingerprint analyses showed that different wastewater treatment systems harbored distinct AOB communities.However,there was no remarkable difference among the AOB TRFLP profiles from different parts of the same system.The T-RFLP fingerprints showed that a full-scale wastewater treatment plant(WWTP) contained a larger number of dominant AOB species than a pilot-scale reactor.The source of influent affected the AOB community,and the WWTPs treating domestic wastewater contained a higher AOB diversity than those receiving mixed domestic and industrial wastewater.However,the AOB community structure was little affected by the treatment process in this study.Phylogenetic analysis of the cloned amoA genes clearly indicated that all the dominant AOB in the systems was closely related to Nitrosomonas spp.not to Nitrosospira spp.Members of the Nitrosomonas oligotropha and Nitrosomonas communis clusters were found in all samples,while members of Nitrosomonas europaea cluster occurred in some systems.Xiaohui Wang Xianghua Wen Craig Criddle George Wells Jie Zhang Yin Zhao 2010Journal of Environmental Sciences2010,22,4:17

8浅议非英语专业英语口语教学改革显示文摘非英语专业学生口语能力有待提高。如何提高学生的口语水平始终是英语教学中的难点和重点。传统教学模式下的大学英语教学束缚了学生学习潜能的发挥。大学英语教学模式的改革可以考虑采用“任务型教学法”。任务型教学模式是20年来交际教学思想的一种发展形态,它把语言运用的基本理念转化为具有实践意义的课堂教学模式。本研究将任务型教学理念应用于非英语专业英语口语教学之中,通过对任务型教学理论的定义、特征和理论基础等方面的阐析,提出任务型口语教学的总体设计思路和具体教学改革措施。吴雪松 Hany Messiha Bryan Wells Ann Vlietinck 2006江苏技术师范学院学报2006,12,3:10
9Alcoholic pancreatitis:New insights into the pathogenesisand treatment显示文摘Acute pancreatitis is a necro-inflammatory disease of the exocrine pancreas that is characterized by inappropriate activation of zymogens, infiltration of the pancreas by inflammatory cells, and destruction of the pancreatic exocrine cells. Acute pancreatitis can progress to a severe life-threatening disease. Currently there is no pharmacotherapy to prevent or treat acute pancreatitis. One of the more common factors associated with acute pancreatitis is alcohol abuse. Although commonly associated with pancreatitis alcohol alone is unable to cause pancreatitis. Instead, it appears that alcohol and its metabolic by-products predispose the pancreas to damage from agents that normally do not cause pancreatitis, or to more severe disease from agents that normally cause mild pancreatic damage. Over the last 10 to 20 years, a tremendous amount of work has defined a number of alcohol-mediated biochemical changes in pancreatic cells. Among these changes are: Sustained levels of intracellular calcium, activation of the mitochondrial permeability transition pore, endoplasmic reticulum stress, impairment in autophagy, alteration in the activity of transcriptional activators, and colocalization of lysosomal and pancreatic digestive enzymes. Elucidation of these changes has led to a deeper understanding of the mechanisms by which ethanol predisposes acinar cells to damage. This greater understanding has revealed a number of promising targets for therapeutic intervention. It is hoped that further investigation of these targets will lead to the development of pharmacotherapy that is effective in treating and preventing the progression of acute pancreatitis.Dahn L Clemens Katrina J Schneider Christopher K Arkfeld Jaclyn R Grode Mark A Wells Shailender Singh 2016World Journal of Gastrointestinal Pathophysiology2016,7,1:10

13Economic valuation of gas regulation as a service by rice-duck-fish complex ecosystem显示文摘Valuating the function of ecosystem services is crucial for accounting green GDP, making a conserva-tion policy of ecological environment and the decision of regional development as well as sustainable development strategy. Rice-duck-f ish symbiosis has been promoted in several developing countries as a way of increasing incomes for rice farmers, but investigations of its value have mainly focused on direct economic benefi ts, such as food and raw material production. Few studies have been conducted on the estimation of indirect services provided by rice-duck-fi sh complex ecosystem. The gas regulation service and its economic values provided by rice-duck-f ish complex ecosystem were studied in Wuhan, China. The major components of gas regulation are O2 emission and greenhouse gases (GHGs, CO2) regulation. The results show that O2 emission from different treatments (including rice-duck (RD), rice-f ish (RF), rice-duck-f ish (RDF) and rice (CK)) ranged from 26,370 kg/ha to 33,910 kg/ha per year, with an eco-nomic value of 10,050-12,920 yuan/ha per year (Chinese currency: 1 euro =10.2475 yuan, August 28, 2007). The net GHGs exchange varied from 1,200 to 3,320 kg/ha per year, and its economic value ranged from 1,040 yuan/ha to 2,900 yuan/ha per year. Consequently, the total economic value of gas regulation provided by symbiosis complex ecosystems ranged from 11,090 yuan/ha to 15,820 yuan/ha per year, and the maximum overall economic value of gas regulation was provided by RDF complex ecosystem. The work will be useful for further understanding of the func-tions of rice-duck-fi sh complex ecosystem services and supplying the theoretical references to agricultural policy.Yuan Welling Cao Cougui Wang Jinping 2008Ecological Economy2008,4,3:10

16Surface texture and friction characteristics of diamond-ground concrete and asphalt pavements显示文摘Recently,diamond grinding has gained increasing attention as pavement preservation treatment to restore desired surface characteristics,particularly friction.Compared to other pavement preservation treatments such as surface overlays and high friction surface treatments,diamond grinding may cost less,save construction time,or require minimum maintenance.Diamond grinding produces longitudinal,continuous,and line-type texture that contains corrugations with evenly spaced ridges.The improved surface texture will immediately enhance pavement surface friction and reduce the possibility of hydroplaning in rainy weather.However,little information has been documented on the texture characteristics and long-term friction performance of diamond-ground pavements.A field evaluation was conducted to examine the surface texture and friction characteristics in diamondground concrete and asphalt pavements by the authors.Five pavement test sections,including two diamond-ground concrete pavements,one diamond-ground concrete bridge deck,one diamond-ground asphalt pavement,and one transversely tined concrete pavement,were selected for evaluation.Laser scanner testing was performed to capture both macro and microtexture profiles.Locked wheel testing was performed to measure the friction numbers.The test results were examined and compared so as to evaluate two performances,after construction and long-term friction performance of diamond-ground pavements.It was found that longitudinal diamond grinding can provide durable,satisfactory surface friction performance for both concrete and asphalt pavements.Shuo Li Dwayne Harris Tim Wells 2016Journal of Traffic and Transportation Engineering(English Edition)2016,3,5:5
