1成都平原蔬菜生产中灌溉水对农药渗漏的影响研究显示文摘针对成都平原蔬菜生产中大量施用农药、大量灌水的特点,首次在国内应用欧洲官方成熟的农药评估模型——PEARL模型,研究评估了成都平原当前蔬菜生产中的灌溉方式对两种不同特性农药的渗漏的影响。杀毒矾(土壤吸附力(KOM)为0 L/kg,半衰期(DT50)为80 d)在没有灌溉条件下,其渗出土体时的最大质量浓度是190μg.L-1,而有灌溉条件下其渗出质量浓度则可达523μg.L-1,是没有灌溉条件下的2.75倍。三唑磷(KOM为200 L.kg-1,DT50为60 d)在没有灌溉条件下,其渗出土体时的最大质量浓度是0.025μg.L-1,而有灌溉条件下其渗出质量浓度为0.13μg.L-1,比没有灌溉时提高了4.2倍。不管有没有灌溉三唑磷在该地区对地下水的污染风险都很小,而杀毒矾的风险则很高。因此,农药的化学特性是影响农药渗漏的最重要的因子。在蔬菜生产中应尽量选用被土壤吸附力强、半衰期短的农药,例如:三唑磷;农药在土壤中的移动载体是土壤水,不合理的灌溉会大大地加大农药淋溶,应当多使用微喷、滴灌等节水灌溉措施,减少使用漫灌等耗水多的原始灌溉方式。林超文 陈一兵 黄晶晶 Rik van den Bosch Mechteld M.S.ter Horst 2005生态环境2005,14,5:12
2Glutamate reduces experimental intestinal hyperpermeability and facilitates glutamine support of gut integrity显示文摘AIM:To assess whether glutamate plays a similar role to glutamine in preserving gut wall integrity.METHODS:The effects of glutamine and glutamate on induced hyperpermeability in intestinal cell lines were studied.Paracellular hyperpermeability was induced in Caco2.BBE and HT-29CL.19A cell lines by adding phorbol-12,13-dibutyrate(PDB) apically,after which the effects of glutamine and glutamate on horseradish peroxidase(HRP) diffusion were studied.An inhibitor of glutamate transport(L-trans-pyrrolidine-2,4-dicarboxylic acid:trans-PDC) and an irreversible blocker(acivicin) of the extracellular glutamine to glutamate converting enzyme,γ-glutamyltransferase,were used.RESULTS:Apical to basolateral HRP flux increased significantly compared to controls not exposed to PDB (n=30,P<0.001).Glutamine application reduced hyperpermeability by 19%and 39%in the respective cell lines.Glutamate application reduced hyperpermeability by 30%and 20%,respectively.Incubation of HT29CL.19A cells with acivicin and subsequent PDB and glutamine addition increased permeability levels.Incubation of Caco2.BBE cells with trans-PDC followed by PDB and glutamate addition also resulted in high permeability levels.CONCLUSION:Apical glutamate-similar to glutaminecan decrease induced paracellular hyperpermeability.Extracellular conversion of glutamine to glutamate and subsequent uptake of glutamate could be a pivotal step in the mechanism underlying the protective effect of glutamine.Mechteld AR Vermeulen Jeffrey de Jong Mathijs J Vaessen Paul AM van Leeuwen Alexander PJ Houdijk 2011World Journal of Gastroenterology2011,17,12:9

11Surgical treatment of a rare complication after endoscopic stent placement for anastomotic leakage after esophageal resection显示文摘The best approach to achieve cure in esophageal cancer is a combination of chemo-radiation and surgery. However, complications occur in half of patients. The current report, reports a rare but severe complication: Complete obstruction of the esophagus, induced by preoperative chemo-radiation therapy. Normally, strictures are treated by repeated dilatations, however, in case of complete obstruction, the perforation rate of standard blind anterograde wire access and dilation is severely increased. In order to minimize the risk of perforations, the rendezvous technique was introduced. This technique involves an anterograde approach in combination with a retrograde approach in order to open and dilatate the esophagus. While technical success rates between 83% and 100% have been reported in literature, data on clinical outcomes are scarcer. The limited amount of studies available claim that success was achieved in almost half of patients. The patient in our case currently has an oral diet without restrictions and rates his quality of life with a VAS-score ten out of ten.Marjan Klinkert Mechteld C de Jong Meindert N Sosef Annick B van Nunen Henricus J Belgers 2017World Journal of Surgical Procedures2017,7,1:1
