1Long-term outcome and prognostic factors of patients with hilar cholangiocarcinoma显示文摘AIM: To evaluate the long-term outcome and prognostic factors of patients with hilar cholangiocarinoma. METHODS: Ninety-six consecutive patients underwent treatment for malignant hilar bile duct tumors during 1995–2005. Of the 96 patients, 20 were initially treated with surgery (n = 2 R0 / n = 18 R1). In non-operated patients, data analysis was performed retrospectively. RESULTS: Among the 96 patients, 76 were treated with endoscopic transpapillary (ERC, n = 45) and/or percutaneous transhepatic biliary drainage (PTBD, n = 31). The mean survival time of these 76 patients undergoing palliative endoscopic and/or percutaneous drainage was 359 ± 296 d. The mean survival time of patients with initial bilirubin levels > 10 mg/dL was significantly lower (P < 0.001) than patients with bilirubin levels < 10 mg/dL. The mean survival time of patients with Bismuth stage Ⅱ (n = 8), Ⅲ (n = 28) and Ⅳ (n = 40) was 496 ± 300 d, 441 ± 385 d and 274 ± 218 d, respectively. Thus, patients with advanced Bismuth stage showed a reduced mean survival time, but the difference was not significant. The type of biliary drainage had no significant beneficial effect on the mean survival time (ERC vs PTBD, P = 0.806). CONCLUSION: Initial bilirubin level is a significant prognostic factor for survival of patients. In contrast, age, tumor stage according to the Bismuth-Corlette classification, and types of intervention are not significant prognostic parameters for survival. Palliative treatment with endoscopic or percutaneous biliary drainage is still suboptimal, new diagnostic and therapeutic tools need to be evaluated.Andreas Weber Sonja Landrock Jochen Schneider Manfred Stangl Bruno Neu Peter Born Meinhard Classen Thomas Rsch Roland M Schmid Christian Prinz 2007World Journal of Gastroenterology2007,13,9:23
2Randomized trial in malignant biliary obstruction:Plastic vs partially covered metal stents显示文摘AIM:To compare efficacy and complications of par-tially covered self-expandable metal stent(pcSEMS)to plastic stent(PS)in patients treated for malignant,infrahilar biliary obstruction.METHODS:Multicenter prospective randomized clinical trial with treatment allocation to a pcWallstent(SEMS)or a 10 French PS.Palliative patients aged≥18,for infrahilar malignant biliary obstruction and a Karnofsky performance scale index>60%from 6 participating North American university centers.Primary endpoint was time to stent failure,with secondary outcomes of death,adverse events,Karnofsky performance score and short-form-36 scale administered on a three-monthly basis for up to 2 years.Survival analyses were performed for stent failure and death,with Cox proportional hazards regression models to determine significant predictive characteristics.RESULTS:Eighty-five patients were accrued over 37mo,42 were randomized to the SEMS group and 83patients were available for analyses.Time to stent failure was 385.3±52.5 d in the SEMS and 153.3±19.8 d in the PS group,P=0.006.Time to death did not differ between groups(192.3±23.4 d for SEMS vs211.5±28.0 d for PS,P=0.70).The only significant predictor was treatment allocation,relating to the time to stent failure(P=0.01).Amongst other measured outcomes,only cholangitis differed,being more common in the PS group(4.9%vs 24.5%,P=0.029).The small number of patients in follow-up limits longitudinal assessments of performance and quality of life.From an initially planned 120 patients,only 85 patients were recruited.CONCLUSION:Partially covered SEMS result in a longer duration till stent failure without increased complication rates,yet without accompanying measurable benefits in survival,performance,or quality of life.Peter L Moses Khalid M AlNaamani Alan N Barkun Stuart R Gordon Roger D Mitty M Stanley Branch Thomas E Kowalski Myriam Martel Viviane Adam 2013World Journal of Gastroenterology2013,19,46:6
3Coexpression of receptor-tyrosine-kinases in gastric adenocarcinoma-a rationale for a molecular targeting strategy?显示文摘AIM: To define the (co-)expression pattern of target receptor-tyrosine-kinases (RTK) in human gastric adenocarcinoma. METHODS: The (co-)expression pattern of VEGFR1-3,PDGFRα/b and EGFR1 was analyzed by RT-PCR in 51 human gastric adenocarcinomas. In addition,IHC staining was applied for confirmation of expression and analysis of RTK localisation. RESULTS: The majority of samples revealed a VEGFR1 (98%),VEGFR2 (80%),VEGFR3 (67%),PDGFRα (82%) and PDGFRβ(82%) expression,whereas only 62% exhibited an EGFR1 expression. 78% of cancers expressed at least four out of six RTKs. While VEGFR1-3 and PDGFRα revealed a predominantly cytoplasmatic staining in tumor cells,accompanied by an additional nuclear staining for VEGFR3 ,EGFR1 was almost exclusively detected on the membrane of tumor cells. PDGFRβ was restricted to stromal pericytes,which also depicted a PDGFRα expression.receptor-tyrosine-kinases coexpression in gastric adenocarcinoma and might therefore encourage an application of multiple-target RTK-inhibitors within a combination therapy.Daniel Drescher Markus Moehler Ines Gockel Kirsten Frerichs Annett Müller Friedrich Dünschede Thomas Borschitz Stefan Biesterfeld Martin Holtmann Thomas Wehler Andreas Teufel Kerstin Herzer Thomas Fischer Martin R Berger Theodor Junginger Peter R Galle Carl C Schimanski 2007World Journal of Gastroenterology2007,13,26:4

8The effects of Spirulina on anemia and immune function in senior citizens显示文摘Anemia and immunological dysfunction(i.e.immunosenescence)are commonly found in older subjects and nutritional approaches are sought to counteract these phenomena.Spirulina is a filamentous and multicellular bule-green alga capable of reducing inflammation and also manifesting antioxidant effects.We hypothesized that Spirulina may ameliorate anemia and immunosenescence in senior citizens with a history of anemia.We enrolled 40 volunteers of both sexes with an age of 50 years or older who had no history of major chronic diseases.Participants took a Spirulina supplementation for 12 weeks and were administered comprehensive dietary questionnaires to determine their nutritional regimen during the study.Complete cell count(CCC)and indoleamine 2,3-dioxygenase(IDO)enzyme activity,as a sign of immune function,were determined at baseline and weeks 6 and 12 of supplementation.Thirty study participants completed the entire study and the data obtained were analyzed.Over the 12-week study period,there was a steady increase in average values of mean corpuscular hemoglobin in subjects of both sexes.In addition,mean corpuscular volume and mean corpuscular hemoglobin concentration also increased in male participants.Older women appeared to benefit more rapidly from Spirulina supplements.Similarly,the majority of subjects manifested increased IDO activity and white blood cell count at 6 and 12 weeks of Spirulina supplementation.Spirulina may ameliorate anemia and immunosenescence in older subjects.We encourage large human studies to determine whether this safe supplement could prove beneficial in randomized clinical trials.Carlo Selmi Patrick SC Leung Laura Fischer Bruce German Chen-Yen Yang Thomas P Kenny Gerry R Cysewski M Eric Gershwin 2011Cellular & Molecular Immunology2011,8,3:2

12Interferon-γ inhibits ghrelin expression and secretion via a somatostatin-mediated mechanism显示文摘AIM:To investigate if and how the proinflammatory cytokine interferon γ(IFNγ) affects ghrelin expression in mice.METHODS:The plasma concentration of ghrelin,andgastric ghrelin and somatostatin expression,were examined in wild-type mice and mice infected with Helicobacter pylori(H.pylori).Furthermore,ghrelin expression was examined in two achlorhydric mouse models with varying degrees of gastritis due to bacterial overgrowth.To study the effect of IFNγ alone,mice were given a subcutaneous infusion of IFNγ for 7 d.Finally,the influence of IFNγ and somatostatin on the ghrelin promoter was characterized.RESULTS:H.pylori infection was associated with a 50% reduction in ghrelin expression and plasma concentration.Suppression of ghrelin expression was inversely correlated with gastric inflammation in achlorhdyric mouse models.Subcutaneous infusion of IFNγ suppressed fundic ghrelin mRNA expression and plasma ghrelin concentrations.Finally,we showed that the ghrelin promoter operates under the control of somatostatin but not under that of IFNγ.CONCLUSION:Gastric infection and inflammation is associated with increased IFNγ expression and reduced ghrelin expression.IFNγ does not directly control ghrelin expression but inhibits it indirectly via somatostatin.Jesper AB Strickertsson Kristina BV DΦssing Anna JM Aabakke Hans-Olof Nilsson Thomas VO Hansen Ulrich Knigge Andreas Kjr Torkel Wadstrm Lennart Friis-Hansen 2011World Journal of Gastroenterology2011,17,26:2
