| 1 | Endoscopic transluminal pancreatic necrosectomy using a self-expanding metal stent and high-flow water-jet system显示文摘Walled-off pancreatic necrosis and a pancreatic abscess are the most severe complications of acute pancreatitis. Surgery in such critically ill patients is often associated with significant morbidity and mortality within the first few weeks after the onset of symptoms. Minimal invasive approaches with high success and low mortality rates are therefore of considerable interest. Endoscopic therapy has the potential to offer safe and effective alternative treatment. We report here on 3 consecutive patients with infected walled-off pancreatic necrosis and 1 patient with a pancreatic abscess who underwent direct endoscopic necrosectomy 19-21 d after the onset of acute pancreatitis. The infected pancreatic necrosis or abscess was punctured transluminally with a cystostome and, after balloon dilatation, a non-covered self-expanding biliary metal stent was placed into the necrotic cavity. Following stent deployment, a nasobiliary pigtail catheter was placed into the cavity to ensure continuous irrigation. After 5-7 d, the metal stent was removed endoscopically and the necrotic cavity was entered with a therapeutic gastroscope. Endoscopic debridement was performed via the simultaneous application of a high-flow water-jet system; using a flush knife, a Dormia basket, and hot biopsy forceps. The transluminal endotherapy was repeated 2-5 times daily during the next 10 d. Supportive care included parenteral antibiotics and jejunal feeding. All patients improved dramatically and with resolution of their septic conditions; 3 patients were completely cured without any further complications or the need for surgery. One patient died from a complication of prolonged ventilation severe bilateral pneumonia, not related to the endoscopic procedure. No procedure related complications were observed. Transluminal endoscopic necrosectomy with temporary application of a self-expanding metal stent and a high-flow water-jet system shows promise for enhancing the potential of this endoscopic approach in patients with walled-off pancreatic necrosis and/or a pancreatic abscess. | István Hritz Roland Fejes András Székely Iván Székely László Horváth gnes Sárkány ron Altorjay László Madácsy | 2013 | World Journal of Gastroenterology2013，19，23： | 10 |
| 2 | Incidence of brain metastasis in patients with esophageal carcinoma显示文摘AIM:To determine the incidence of brain metastasis in a contemporary group of patients with carcinoma of the esophagus.METHODS:Retrospective analysis of 53 patients with esophageal carcinoma who received radiotherapy as a component of treatment between 1998 and 2007,including patient and tumor characteristics,and subsequent diagnosis of brain metastasis.The association between the histological type of esophageal cancer and the incidence of brain metastasis was assessed using Fisher's exact test.RESULTS:Forty-four of the fifty-three patients in this study had adenocarcinoma and nine had squamous cell carcinoma,ranging from stage ⅡA-ⅣB.Primary treatment was surgery with neoadjuvant chemoradiotherapy (trimodality therapy) in 19% of patients;chemoradiotherapy in 42%;and surgery and adjuvant radiotherapy in 7%.Twenty-five percent of patients inthis study received palliative radiotherapy.The overall incidence of brain metastasis in this cohort was 13%.Adenocarcinoma was the primary tumor histology in all of the patients who developed brain metastasis,representing an incidence of 16% in this subgroup.No patients with squamous cell carcinoma received trimodality therapy.The association between histology and brain metastasis was not statistically significant.CONCLUSION:The incidence of brain metastasis in this contemporary cohort of patients with esophageal carcinoma is higher than previously reported and was confined to those with adenocarcinoma. | Ron S Smith Robert C Miller | 2011 | World Journal of Gastroenterology2011，17，19： | 6 |
| 3 | Intestinal 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 Gyrffy Péter László Lakatos Mária Papp András Arató Gábor Veres | 2012 | World Journal of Gastroenterology2012，18，25： | 5 |
| 4 | Understanding 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 | 2019 | Journal of Genetics and Genomics2019，46，4： | 4 |

| 6 | Characteristics 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 Gyrffy ron Cseh Katalin Eszter Müller András Arató Gábor Veres | 2013 | World Journal of Gastroenterology2013，19，24： | 3 |
| 7 | Synchronous electrogastrographic and manometric study of the stomach as an esophageal substitute显示文摘AIM: To investigate the electric and contractile mechanisms involved in the deranged function of the transposed stomach in relation to the course of the symptoms and the changes in contractile and electrical parameters over time.METHODS: Twenty-one patients after subtotal esophagectomy and 18 healthy volunteers were studied.Complaints were compiled by using a questionnaire, and a symptom score was formed. Synchronous electrogastrography and gastric manometry were performed in the fasting state and postprandially.RESULTS: Eight of the operated patients were symptomfree and 13 had symptoms. The durations of the postoperative periods for the symptomatic (9.1±6.5 mo)and the asymptomatic (28.3±8.8 mo) patients were significantly different. The symptom score correlated negatively with the time that had elapsed since the operation. The percentages of the dominant frequency in the normogastric, bradygastric and tachygastric ranges differed significantly between the controls and the patients.A significant difference was detected between the power ratio of the controls and that of the patients. The occurrence of tachygastria in the symptomatic and the symptom-free patients correlated negatively both with the time that had elapsed and with the symptom score. There was a significant increase in motility index after feeding in the controls, but not in the patients. The contractile activity of the stomach increased both in the controls and in the symptom-free patients. In contrast, in the group of symptomatic patients, the contractile activity decreased postprandially as compared with the fasting state.CONCLUSION: The patients' post-operative complaints and symptoms change during the post-operative period and correlate with the parameters of the myoelectric and contractile activities of the stomach. Tachygastria seems to be the major pathogenetic factor involved in the contractile dysfunction. | Ferenc Izbéki Tibor Wittmann Sándor (O|')dor Balázs Botos (A|')ron Altorjay | 2005 | World Journal of Gastroenterology2005，11，8： | 2 |
| 8 | COVID-19-associated diarrhea显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)recently emerged as a highly virulent respiratory pathogen that is known as the causative agent of coronavirus disease 2019(COVID-19).Diarrhea is a common early symptom in a significant proportion of patients with SARS-CoV-2 infection.SARS-CoV-2 can infect and replicate in esophageal cells and enterocytes,leading to direct damage to the intestinal epithelium.The infection decreases the level of angiotensinconverting enzyme 2 receptors,thereby altering the composition of the gut microbiota.SARS-CoV-2 elicits a cytokine storm,which contributes to gastrointestinal inflammation.The direct cytopathic effects of SARS-CoV-2,gut dysbiosis,and aberrant immune response result in increased intestinal permeability,which may exacerbate existing symptoms and worsen the prognosis.By exploring the elements of pathogenesis,several therapeutic options have emerged for the treatment of COVID-19 patients,such as biologics and biotherapeutic agents.However,the presence of SARS-CoV-2 in the feces may facilitate the spread of COVID-19 through fecal-oral transmission and contaminate the environment.Thus gastrointestinal SARS-CoV-2 infection has important epidemiological significance.The development of new therapeutic and preventive options is necessary to treat and restrict the spread of this severe and widespread infection more effectively.Therefore,we summarize the key elements involved in the pathogenesis and the epidemiology of COVID-19-associated diarrhea. | Klara Megyeri Áron Dernovics Zaid I I Al-Luhaibi András Rosztóczy | 2021 | World Journal of Gastroenterology2021，27，23： | 2 |
