| 1 | Laparoscopic distal pancreatectomy for adenocarcinoma of the pancreas显示文摘Since the first report on laparoscopic distal pancreatec tomy(LDP) appeared in the 1990 s, the procedure ha been performed increasingly frequently to treat both benign and malignant lesions of the pancreas. Man earlier publications have shown LDP to be a good alter native to open distal pancreatectomy for benign lesions although this has never been studied in a prospective randomized manner. The evidence for the use of LDP to treat adenocarcinoma of the pancreas is not as we established. The purpose of this review is to evaluat the current evidence for LDP in cases of pancreati adenocarcinoma. We conducted a review of English language publications reporting LDP results between1990 and 2013. All studies reporting results in patient with histologically proven pancreatic adenocarcinom were included. Thirty-nine publications were found and included in the results for a total of 309 cases of pan creatic adenocarcinoma(potential double publication were not eliminated). Most LDP procedures are per formed in selected cases and generally involve smalle tumors than open distal pancreatectomy(ODP) proce dures. Some of the papers report unselected cases andinclude procedures on larger tumors. The number of lymph nodes harvested using LDP is comparable to the number obtained with ODP, as is the frequency of R0 resections. Current data suggest that similar short term oncological results can be obtained using LDP as those obtained using ODP. | Bergthor Bjrnsson Per Sandstrm | 2014 | World Journal of Gastroenterology2014，20，37： | 1 |
| 2 | Nitrite,a novel method to decrease ischemia/reperfusion injury in the rat liver显示文摘AIM:To investigate whether nitrite administered prior to ischemia/reperfusion(I/R)reduces liver injury.METHODS:Thirty-six male Sprague-Dawley rats were randomized to 3 groups,including sham operated(n=8),45-min segmental ischemia of the left liver lobe(IR,n=14)and ischemia/reperfusion(I/R)preceded by the administration of 480 nmol of nitrite(n=14).Serum transaminases were measured after 4 h of reperfusion.Liver microdialysate(MD)was sampled in 30-min intervals and analyzed for glucose,lactate,pyruvate and glycerol as well as the total nitrite and nitrate(NOx).The NOx was measured in serum.RESULTS:Aspartate aminotransferase(AST)at the end of reperfusion was higher in the IR group than in the nitrite group(40±6.8μkat/L vs 22±2.6μkat/L,P=0.022).Similarly,alanine aminotransferase(ALT)was also higher in the I/R group than in the nitrite group(34±6μkat vs 14±1.5μkat,P=0.0045).The NOx in MD was significantly higher in the nitrite group than in the I/R group(10.1±2.9μmol/L vs 3.2±0.9μmol/L,P=0.031)after the administration of nitrite.During ischemia,the levels decreased in both groups and then increased again during reperfusion.At the end of reperfusion,there was a tendency towards a higher NOx in the I/R group than in the nitrite group(11.6±0.7μmol/L vs 9.2±1.1μmol/L,P=0.067).Lactate in MD was significantly higher in the IR group than in the nitrite group(3.37±0.18 mmol/L vs 2.8±0.12 mmol/L,P=0.01)during ischemia and the first 30 min of reperfusion.During the same period,glycerol was also higher in the IRI group than in the nitrite group(464±38μmol/L vs 367±31μmol/L,P=0.049).With respect to histology,there were more signs of tissue damage in the I/R group than in the nitrite group,and29%of the animals in the I/R group exhibited necrosis compared with none in the nitrite group.Inducible nitric oxide synthase transcription increased between early ischemia(t=15)and the end of reperfusion in both groups.CONCLUSION:Nitrite administered before liver ischemia in the rat liver reduces anaerobic metabolism and cell necrosis,which could be important in the clinical setting. | Bergthor Bjrnsson Linda Bojmar Hans Olsson Tommy Sundqvist Per Sandstrm | 2015 | World Journal of Gastroenterology2015，21，6： | 8 |
| 3 | 参与式管理解决冲突:遥感和GIS用作瑞典北部驯鹿业土地利用需求信息交流的工具显示文摘在解决复杂的土地管理问题时,对短缺或者有争执的资源进行地理评估有助于不同利益相关者之间沟通认识和增进理解。本文中,我们说明如何使用遥感和GIS收集和汇总瑞典北部驯鹿放牧者和其他土地使用者(林业、采矿业、旅游业等等)的土地使用活动及使用模式的信息。该项目主要基于最终的土地使用者,即驯鹿放牧者们所做的工作,体现了面向土地使用者的新的努力。发展驯鹿业的土地利用规划的基础有以下几个方面:收集并数字化传统的驯鹿栖息地生态学和景观信息;将这些信息与来自野外调查及基于人造卫星观测的植被分类结果整合;绘制其他土地使用者的活动情况图。最终的土地利用规划提供的信息有利于驯鹿放牧者与其他利益相关者之间的磋商,并有助于驯鹿管理实施。该项目可作为一种大众参与和计划编制的模式,从而使本土信息和先进的遥感技术融入一个交互式的过程中。 | Per Sandstrm Tina Granqvist Pahlén Lars Edenius Hans Tφmmervik Olle Hagner Leif Hemberg Hkan Olsson Karin Baer Thomas Stenlund Lars Gran Brandt Mikael Egberth 周立志 程利群 | 2003 | AMBIO-人类环境杂志2003，32，8： | 4 |
