Objective:The aim of this study is to develop a nomogram for prediction of pathologic complete remission(p CR)after preoperative chemoradiotherapy(CRT)for rectal ***:m RNA expression levels of seven molecular markers[p53,p21,Ki-67,vascular endothelial growth factor(VEGF),CD133,CD24,CD44]were measured by reverse transcriptase polymerase chain reaction(RTPCR)in 120 rectal *** findings of clinical complete remission(c CR)and biologic variables were used to construct nomogram in the training group(n=80),which was validated in the validation group(n=40).Results:m RNA expression levels of four markers(p53,p21,Ki67,CD133)correlated with p CR(24/80,30.0%)in the training *** expression of p53 and/or high expression of p21,Ki67 and CD133 showed greater p CR rate.p CR was shown in 18(69.2%)of 26 cases showing endoscopic c CR in the training *** p CR rate was demonstrated in lower tumor location than middle tumor(19/49,38.8%vs.5/31,16.1%).A nomogram for prediction of p CR was developed from the multivariate prediction model using these six variables,which showed good discrimination ability in the training group[area under the curve(AUC)=0.945]and validation group(AUC=0.922).The calibration plot showed good agreement between actual and predicted p CR in both patient ***:Nomogram for assessment of p CR can be useful for making treatment decisions after CRT according to predicted responses.

Eosinophilic gastroenteritis presenting as small bowel obstruction: A case report and review of the literature

World Journal of Gastroenterology 2007年第11期13卷 1758-1760页

作者： Min Young Yun Young Up Cho In Suh Park Sun Keun Choi Sei joong kim Seok Hwan Shin Kyung Rae kim Department of Surgery College of Medicine Inha University Incheon Korea Department of Pathology College of Medicine Inha University Incheon Korea

Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract. Recently, the authors experienced a case of eosinophilic gastroenteritis presenting as small bowel obstruction. A 51-year old woman was admitted to our hospital complaining of abdominal pain and vomiting. Physical examination revealed a distended abdomen with diffuse tenderness. Complete blood count showed mild leukocytosis without eosinophilia. Computed tomography confirmed a dilatation of the small intestine with ascites. An emergency laparotomy was performed for a diagnosis of peritonitis due to intestinal obstruction. Segmental resection of the ileum and end to end anastomosis were performed. Histologically, there was a dense infiltration of eosinophils throughout the entire thickness of ileal wall and eosinophilic enteritis was diagnosed. The patient recovered well, and was free from gastrointestinal symptoms at the time when we reported her disease.

Vaporization reduction characteristics of aqueous ammonia solutions by the addition of ethylene glycol, glycerol and glycine to the CO_2 absorption process

Aqueous ammonia （NH3） solution can be used as an alternative absorption for the control of CO2 emitted from flue gases due to its high absorption capacity, fast absorption rate and low corrosion problem. The emission of CO2 from iron and steel plants requires much attention, as they are higher than those emitted from power plants at a single point source. In the present work, low concentration ammonia liquor, 9 wt.%, was used with various additives to obtain the kinetic properties using the blast furnace gas model. Although a solution with a high ammonia concentration enables high CO2 absorption efficiency, ammonium ions are lost as ammonia vapor, resulting in reduced CO2 absorption due to the lower concentration of the ammonia absorbent. To decrease the vaporization of ammonia, ethylene glycol, glycerol and glycine, which contain more than one hydroxyl radical, were chosen. The experiments were conducted at 313 K similar to the CO2 absorption conditions for the blast furnace gas model.

作者： Cheol-joong kim Dong-Bok WON 等 R&Dcenter SKcorporationTaejon305-370Korea DeptartmentofChemicalEngineering ChungnamNationalUniversityTaejon305-765Korea

The phase behaviors of toluene/polycyclic aromatic hydrocarbon mixture systems were investigated with a continuous-flow type apparatus at 573.2, 598.2, 623.2 and 648.2 K, while the pressure changed from 1 to 5MPa. The pseudo-binary phase behaviors were predicted with the Peng-Robinson equation of state with interaction parameters between toluene and pseudo-components considered. The phase diagrams of the system have been classified following the category of phase boundary diagram models. The extraction selectivity and efficiency of tolu-ene as a solvent was discussed by comparing with that of hexane. The prediction model for selectivity was also suggested.
