AIM： Pancreatic pseudocysts （PPC） as a complication of pancreatitis are approached only in the case of abdominal pain, infection, bleeding, and compression onto the gastrointestinal tract or biliary tree. METHODS： From 02/01/2002 to 05/31/2004, all con- secutive patients with symptomatic PPC who underwent an interventional endoscopic approach were evaluated in this pilot case-series study： Group （Gr.） Ⅰ-Primary percutaneous （external）, ultrasound-guided drainage. Gr. Ⅱ- Primary EUS-guided cystogastrostomy. Gr. Ⅲ-EUS-guided cystogastrostomy including intracystic necrosectomy. RESULTS：（=＂follow up＂： n = 27）： Gr. Ⅰ （n = 9; 33.3%）： no complaints （n = 3）; change of an external into an internal drainage （n = 4）; complications：（a） bleeding （n = 1） followed by 3 d at ICU, discharge after 40 d; （b） septic shock （n = 1） followed by ICU and several laparotomies for programmed lavage and necrosectomy, death after 74 d. Gr. Ⅱ （n = 13; 48.1%）： no complaints （n = 11）; external drainage （n = 2）; complications/problems out of the 13 cases： 2nd separate pseudocyst （n = 1） with external drainage （since no communication with primary internal drainage）; infection of the residual cyst （n = 1）＋ following external drainage; spontaneous PPC perforation （n = 1）＋ following closure of the opening of the cystogastrostomy using clips and subsequently ICU for 2 d. Gr. Ⅲ （n = 5; 18.5%）： no complaints in all patients, in average two endoscopic procedures required （range, 2-6）. COnCLUSIOn： Interventional endoscopic management of pancreatic pseudocysts is a reasonable alternative treatment option with low invasiveness compared to surgery and an acceptable outcome with regard to the complication rate （11.1%） and mortality （3.7%）, as shown by these initial study results.

We report on pyramiding different disease resistance genes against fungal pathogens in Canadian winter wheat germplasm based on available DnA markers and gene *** resistance represents a safe, economical and ecological method for protecting plants, growers and the health of consumers. Major diseases of wheat on the Canadian Prairies are common bunt, rusts(leaf, stem and stripe) and Fusarium head blight. Over the years markers for resistance genes against these diseases have been identified and used by the international wheat community. We describe markers that we have used to pyramid different resistance genes and indicate their presence in Canadian winter wheat cultivars issued from the winter wheat breeding program at the Agriculture and Agri-Food Canada,Lethbridge Research and Development Centre, the only winter wheat breeding program in Western Canada actively delivering new varieties for all regions of the Canadian *** sources of resistance and identities of PCR primers and amplification conditions are indicated to enable the transfer and pyramiding of different resistance(R) genes to breeding lines. We conclude by reviewing new tools for identifying R genes in wheat and indicate how mutagenesis and gene editing can help future efforts to extend the protection offered by known R genes.

临床体格检查诊断直肠套叠的精确度

世界核心医学期刊文摘（胃肠病学分册） 2005年第2期1卷 19-20页

作者： Karlbom U. graf W. nilsson S. Phlman L. 赵天智 Department of Surgery University Hospital SE-751 85 Uppsala SwedenDr.

PURPOSE: This study was designed to compare routine clinical examination and d efecography in the diagnosis of rectal intussusception in constipated patients a nd study relationships between rectal intussusception and symptoms. METHODS: A t otal of 127 consecutive patients with functional constipation were examined in t he left-lateral position with rectal palpation and rectoscopy according to a pr otocol. An overall clinical judgment was made if the patient had intussusception , unclear finding, or no intussusception. Defecography was performed without kno wledge of the results of the clinical evaluation. Symptomduration varied between 0.5 to 60 (median, 10) years. All patients fulfilled a bowel questionnaire and all had a full physiologic workup. RESULTS: A diagnosis by digital examination ( P = 0.002) and by rectoscopy (P = 0.002) as well as the overall judgment (P = 0. 0002) was clearly related to a longer intussusception as measured by defecograph y. Five of six intraanal intussusceptions were correctly assessed by clinical examinat ion,whereas the correlation to defecographywas poor in the group with short intu ssusceptions. neither clinical nor defecographic diagnosis of rectal intussuscep tion were related to the main symptoms of constipation but both were associated with a tendency toward lower anal resting pressures (P = 0.04 and P = 0.06) and an obtuse anorectal angle (during evacuation, P = 0.01 and P = 0.01). COnCLUSIOn S: There is no clear relationship between rectal intussusception and constipatio n. However, intussusception is related to sphincter function and may be of clini cal relevance. A normal clinical examination will exclude most long intussuscept ions, whereas a positive finding needs further evaluation with defecography.

不锈钢材料具有良好的抗腐蚀性能,近年来被越来越多地应用于建筑行业,如通风幕墙结构中的不锈钢挂件。但即使是不锈钢挂件,也可能出现严重的腐蚀问题,进而导致整个幕墙结构的破坏。不锈钢挂件材质的选用,必须考虑环境的腐蚀等级及幕墙结构的安装和使用情况。在德国,不锈钢挂件大量地应用于通风幕墙结构中,已经形成了完整的规范体系。中国起步相对较晚,规范体系尚不够完善。本文重点阐述通风幕墙不锈钢挂件可能出现的腐蚀问题,详细介绍德国及欧盟的相关规范内容,最后,结合中国现状,对不锈钢挂件在幕墙结构中的应用提出一些建议。
