1Intestinal alkaline phosphatase in the colonic mucosa of children with inflammatory bowel disease显示文摘AIM:To investigate intestinal alkaline phosphatase(iAP) in the intestinal mucosa of children with inflammatory bowel disease(IBD).METHODS:Colonic biopsy samples were taken from 15 newly diagnosed IBD patients and from 10 healthy controls.In IBD patients,specimens were obtainedboth from inflamed and non-inflamed areas.The iAP mRNA and protein expression was determined by reverse transcription-polymerase chain reaction and Western blotting analysis,respectively.Tissue localization of iAP and Toll-like receptor(TLR) 4 was investigated by immunofluorescent staining.RESULTS:The iAP protein level in the inflamed mucosa of children with Crohn's disease(CD) and ulcerative colitis(UC) was significantly decreased when compared with controls(both P < 0.05).Similarly,we found a significantly decreased level of iAP protein in the inflamed mucosa in CD compared with non-inflamed mucosa in CD(P < 0.05).In addition,the iAP protein level in inflamed colonic mucosa in patients with UC was decreased compared with non-inflamed mucosa in patients with CD(P < 0.05).iAP protein levels in the non-inflamed mucosa of patients with CD were similar to controls.iAP mRNA expression in inflamed colonic mucosa of children with CD and UC was not significantly different from that in non-inflamed colonic mucosa with CD.Expression of iAP mRNA in patients with noninflamed mucosa and in controls were similar.Co-localization of iAP with TLR4 showed intense staining with a dotted-like pattern.iAP was present in the inflamed and non-inflamed mucosa of patients with CD,UC,and in control biopsy specimens,irrespective of whether it was present in the terminal ileum or in the colon.However,the fluorescent signal of TLR4 was more pronounced in the colon compared with the terminal ileum in all groups studied.CONCLUSION:Lower than normal iAP protein levels in inflamed mucosa of IBD patients may indicate a role for iAP in inflammatory lesions in IBD.Based on our results,administration of exogenous iAP enzyme to patients with the active form of IBD may be a therapeutic option.Kriszta Molnár dám Vannay Beáta Szebeni Nóra Fanni Bánki Erna Sziksz ron Cseh Hajnalka Gyrffy Péter László Lakatos Mária Papp András Arató Gábor Veres 2012World Journal of Gastroenterology2012,18,25:5
2经桡动脉行颈动脉狭窄支架成形术的疗效分析显示文摘目的探讨经桡动脉入路行颈动脉狭窄支架成形术的适应证和优势.方法经桡动脉入路在颈内动脉岩部放置阻塞球囊,对38例颈动脉粥样硬化性狭窄患者行支架置入术.其中有症状者29例,无症状者9例.术前均行颈动脉数字减影血管造影(DSA)、脑实质血管DSA、颈动脉多普勒超声及头部MRI等检查.结果术后患者均复查颈动脉DSA和脑实质血管DSA,显示脑部供血均有明显改善,其患侧颈内动脉、皮质下血管显影时间较术前提前0.3~0.8 s,颅内血管血流经过时间缩短0.4~0.7 s.短暂性脑缺血发作(TIA)症状消失.全组无手术死亡病例,无并发症.随访3~15个月,无再狭窄患者.结论当经股动脉入路为相对禁忌时,经桡动脉入路是颈动脉狭窄支架成形术值得选择的一种入路.张佳栋 J G Théron 2005中国脑血管病杂志2005,2,12:4
3Understanding the importance of autophagy in human diseases using Drosophila显示文摘Autophagy is a lysosome-dependent intracellular degradation pathway that has been implicated in the pathogenesis of various human diseases, either positively or negatively impacting disease outcomes depending on the specific context. The majority of medical conditions including cancer, neurodegenerative diseases, infections and immune system disorders and inflammatory bowel disease could probably benefit from therapeutic modulation of the autophagy machinery. Drosophila represents an excellent model animal to study disease mechanisms thanks to its sophisticated genetic toolkit, and the conservation of human disease genes and autophagic processes. Here, we provide an overview of the various autophagy pathways observed both in flies and human cells(macroautophagy, microautophagy and chaperone-mediated autophagy), and discuss Drosophila models of the above-mentioned diseases where fly research has already helped to understand how defects in autophagy genes and pathways contribute to the relevant pathomechanisms.Arindam Bhattacharjee áron Szabó Tamás Csizmadia Hajnalka Laczkó-Dobos Gábor Juhász 2019Journal of Genetics and Genomics2019,46,4:4
4Characteristics of allergic colitis in breast-fed infants in the absence of cow's milk allergy显示文摘AIM: To investigate the characteristics of mucosal le-sions and their relation to laboratory data and long-term follow up in breast-fed infants with allergic colitis. METHODS: In this study 31 breast-fed infants were prospectively evaluated (mean age, 17.4 wk) whose rectal bleeding had not ceased after a maternal elimi-nation diet for cow's milk. Thirty-four age-matched and breast-fed infants (mean age, 16.9 wk) with no rectal bleeding were enrolled for laboratory testing as con-trols. Laboratory findings, colonoscopic and histological characteristics were prospectively evaluated in infants with rectal bleeding. Long-term follow-up with differ-ent nutritional regimes (L-amino-acid based formula or breastfeeding) was also included. RESULTS: Iron deficiency, peripheral eosinophilia andthrombocytosis were significantly higher in patients with allergic colitis in comparison to controls (8.4±3.2 μmol/L vs 13.7±4.7 μmol/L, P<0.001; 0.67±0.49 G/L vs 0.33±0.17 G/L, P<0.001; 474±123 G/L vs 376±89 G/L, P<0.001, respectively). At colonosco-py, lymphonodular hyperplasia or aphthous ulceration were present in 83% of patients. Twenty-two patients were given L-amino acid-based formula and 8 contin-ued the previous feeding. Time to cessation of rectal bleeding was shorter in the special formula feeding group (mean, 1.4 wk; range, 0.5-3 wk) when com-pared with the breast-feeding group (mean, 5.3 wk; range, 2-9 wk). Nevertheless, none of the patients ex-hibited rectal bleeding at the 3-mo visit irrespective of the type of feeding. Peripheral eosinophilia and cessa-tion of rectal bleeding after administration of elemental formula correlated with a higher density of mucosal eosinophils. CONCLUSION: Infant hematochezia, after cow's milk allergy exclusion, is generally a benign and probably self-limiting disorder despite marked mucosal abnor-mality. Formula feeding results in shorter time to cessa-tion of rectal bleeding; however, breast-feeding should not be discouraged in long-lasting hematochezia.Kriszta Molnár Petra Pintér Hajnalka Gyrffy ron Cseh Katalin Eszter Müller András Arató Gábor Veres 2013World Journal of Gastroenterology2013,19,24:3

6Esophageal obstruction due to enteral feed bezoar:A case report and literature review显示文摘This paper describes a rare complication of enteral feeding,esophageal obstruction due to feeding formula bezoar,and reviews the published cases. An attempt to re-insert the nasogastric tube in a chronically ventilated 80-year-old female fed via a nasogastric tube with Jevity failed. An esophagogastroduodenoscopy revealed an 18 cm-long concretion of the feeding formula,fi-lling most of the esophageal lumen,which was removed endo scopically. Forty-two cases of feeding formula esophageal bezoars have been reported in the literature. The formation of feeding formula bezoars is triggered by acidic gastroesophageal reflux. The acidic pH in the esophagus causes clotting of the casein in the formula. Predisposing factors for bezoar formation are:mechanical ventilation,supine position,neurological diseases,diabetes mellitus,hypothyroidism,obesity and history of partial gastrectomy. Diagnosis and removal of the bezoar is done endoscopically. Feeding in a semi-recumbent position,administration of prokinetic agents and proton pump inhibitors may prevent this complication.Esther-Lee Marcus Ron Arnon Arkadiy Sheynkman Yehezkel G Caine Joseph Lysy 2010World Journal of Gastrointestinal Endoscopy2010,2,10:3
