AIMTo investigate the current management of gastric antral webs (GAWs) among adults and identify optimal endoscopic and/or surgical management for these patients. METHODSWe reviewed our endoscopy database seeking to identify patients in whom a GAW was visualized among 24640 esophagogastroduodenoscopies (EGD) over a seven-year period (2006-2013) at a single tertiary care center. The diagnosis of GAW was suspected during EGD if aperture size of the antrum did not vary with peristalsis or if a “double bulb” sign was present on upper gastrointestinal series. Confirmation of the diagnosis was made by demonstrating a normal pylorus distal to the GAW. RESULTSWe identified 34 patients who met our inclusion criteria (incidence 0.14%). Of these, five patients presented with gastric outlet obstruction (GOO), four of whom underwent repeated sequential balloon dilations and/or needle-knife incisions with steroid injection for alleviation of GOO. The other 29 patients were incidentally found to have a non-obstructing GAW. Age at diagnosis ranged from 30-87 years. Non-obstructing GAWs are mostly incidental findings. The most frequently observed symptom prompting endoscopic work-up was refractory gastroesophageal reflux (n = 24, 70.6%) followed by abdominal pain (n = 11, 33.4%), nausea and vomiting (n = 9, 26.5%), dysphagia (n = 6, 17.6%), unexplained weight loss, (n = 4, 11.8%), early satiety (n = 4, 11.8%), and melena of unclear etiology (n = 3, 8.82%). Four of five GOO patients were treated with balloon dilation (n = 4), four-quadrant needle-knife incision (n = 3), and triamcinolone injection (n = 2). Three of these patients required repeat intervention. One patient had a significant complication of perforation after needle-knife incision. CONCLUSIONEndoscopic intervention for GAW using balloon dilation or needle-knife incision is generally safe and effective in relieving symptoms, however repeat treatment may be needed and a risk of perforation exists with thermal t

消除液压装置噪声的新技术

机械 1980年第2期 39-45+60页

作者： stanley j.skaistis 尹世荣国营空气压缩机厂机动科

过去,液压泵产生的噪声掩饰了液体和支承结构传递的噪声。但是,随着液压泵设计的改善,已使得泵的噪声大为降低,这样其他两种噪声源就变得引人注目了。最新的研究结果业已指明了这些一度被人忽视的噪声发生器所产生噪声的消除方法。

AIM： To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm （AAA） repair surgery, METHODS： Nine patients （aged 35-78 years; body mass index （BMI） range： 23-36 kg/m2） post-surgery for AAA repair, and seven healthy control subjects （20-50 years; BMI range： 21-29 kg/m^2） were studied, Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding （Nutrison）. Recordings were analyzed for the frequency, odgin, length of migration, and direction of small intestinal burst activity. Lipid absorption was assessed on the first day and the third day post surgery in a subset of patients using the ^13C-triolein-breath test, and compared with healthy controls. Subjects received a 20-min intraduodenal infusion of 50 mL liquid feed mixed with 200μL ^13C-triolein. End-expiratory breath samples were collected for 6 h and analyzed for ^13CO2 concentration. RESULTS： The frequency of burst activity in the proximal and distal small intestine was higher in patients than in healthy subjects, under both fasting and fed conditions （P〈 0.005）. In patients there was a higher proportion of abnormally propagated bursts （71% abnormal）, which began to normalize by d 3 （25% abnormal） *** absorption data was available for seven patients on d 1 and four patients on d 3 post surgery. In patients, absorption on d 1 post-surgery was half that of healthy control subjects （AUC ^13CO2 1323±244 vs 2646±365; P〈0.05, respectively）, and was reduced to the one-fitch that of healthy controls by d 3 （AUC ^13CO2 470±832 vs 2646±365; P〈 0.05, respectively）. CONCLUSION： Both proximal and distal small intestinal motor activity are transiently disrupted in critically ill patients immediately after major surgery, with abnormal motility patterns extending as far as the ileum. These motor disturbances may contribute to impaired absorption of enteral nutrition, especially when intralumi

A variable chlorine decay rate modeling of the Matsapha town water network was developed based on initial chlorine dosages. The model was adequately described by a second order rate function of the chlorine decay rate with respect to the initial chlorine dose applied. Simulations of chlorine residuals within the Matsapha water distribution network were run using the EPANET 2.0 program at different initial chlorine dosages and using the variable decay rate as described by the second order model. The measurement results indicated that the use of constant decay rate tended to underestimate chlorine residuals leading to potentially excess dosages with the associated chemical cost and side effects. The error between the two rate models varied between 0% and 15%. It is suggested that the use of water quality simulation programs such as EPANET be enhanced through the extension programs that accommodate variable rate modeling of chlorine residuals within distribution systems.
