| 1 | Obstructive jaundice due to hepatobiliary cystadenoma or cystadenocarcinoma显示文摘Hepatobiliary cystadenomas (HBC) and cystadenocarci- nomas are rare cystic lesions. Most patients with these lesions are asymptomatic, but presentation with ob- structive jaundice may occur. The first patient presented with intermittent colicky pain and recurrent obstructive jaundice. Imaging studies revealed a polypoid lesion in the left hepatic duct. The second patient had recurrent jaundice and cholangitis. Endoscopic retrograde cholan- giopancreatography (ERCP) showed a cystic lesion at the confluence of the hepatic duct. In the third patient with intermittent jaundice and cholangitis, cholangioscopy re- vealed a papillomatous structure protruding into the left bile duct system. In the fourth patient with obstructive jaundice, CT-scan showed slight dilatation of the intrahe- patic bile ducts and dilatation of the common bile duct of 3 cm. ERCP showed filling of a cystic lesion. All patients underwent partial liver resection, revealing HBC in the specimen. In the fifth patient presenting with obstructive jaundice, ultrasound examination showed a hyperecho- genic cystic lesion centrally in the liver. The resection specimen revealed a hepatobiliary cystadenocarcinoma. HBC and cystadenocarcinoma may give rise to obstruc- tive jaundice. Evaluation with cross-sectional imaging techniques is useful. ERCP is a useful tool to differentiate extraductal from intraductal obstruction. | Deha Erdogan Olivier RC Busch Erik AJ Rauws Otto M van Delden Dirk J Gouma Thomas M van Gulik | 2006 | World Journal of Gastroenterology2006，12，35： | 26 |
| 2 | Results of percutaneous sclerotherapy and surgical treatment in patients with symptomatic simple liver cysts and polycystic liver disease显示文摘AIM: To evaluate the results of the treatment of simple liver cysts (solitary and multiple) and polycystic liver disease (PLD) using percutaneous sclerotherapy and/or surgical procedures in a single tertiary referral centre. METHODS: Retrospective analysis of 54 patients referred for evaluation and possible treatment of simple liver cysts (solitary and multiple) and PLD, from January 1997 to July 2006. RESULTS: Simple liver cysts were treated in 41 pts (76/) with a mean size of 12.6 cm. The most common reason for referral was abdominal pain or discomfort (85/). Percutaneous sclerotherapy was performed as initial treatment in 30 pts, showing cyst recurrence in 6 pts (20/). Surgical treatment was initially performed in 11 pts with cyst recurrence in 3 pts (27/). PLD was treated in 13 pts (24/) with a mean size of the dominant cyst of 13 cm. Percutaneous sclerotherapy for PLD was performed in 9 pts with recurrence in 7 pts (77.8/). Surgical treatment for PLD was undertaken in 4 pts (30.8/) with recurrence in all. Eventually, 2 pts with PLD in the presence of polycystic kidney disease underwent liver-and kidney transplantation because of deterioration of liver and kidney function. CONCLUSION: The majority of patients with simple liver cysts and PLD are referred for progressive abdominal pain. As initial treatment, percutaneous sclerotherapy is appropriate. Surgical deroofing is indicated in caseof cyst recurrence after percutaneous sclerotherapy. However, the results of percutaneous sclerotherapy and surgical treatment for PLD are disappointing. Partial liver resection is indicated when there is suspicion of a pre-malignant lesion. | Deha Erdogan Otto M van Delden Erik AJ Rauws Olivier RC Busch Johan S Lameris Dirk J Gouma Thomas M van Gulik | 2007 | World Journal of Gastroenterology2007，13，22： | 15 |
| 3 | Helicobacter pylori vac A genotype is a predominant determinant of immune response to Helicobacter pylori CagA显示文摘AIM To evaluate the frequency of Helicobacter pylori(H. pylori) Cag A antibodies in H. pylori infected subjects and to identify potential histopathological and bacterial factors related to H. pylori Cag A-immune response.METHODS Systematic data to H. pylori isolates, blood samples, gastric biopsies for histological and molecular analyses were available from 99 prospectively recruited subjects. Serological profile(anti-H. pylori, anti-Cag A) was correlated with H. pylori isolates(cag A, EPIYA, vac A s/m genotype), histology(Sydney classification) and mucosal interleukin-8(IL-8) m RNA and protein expression. Selected H. pylori strains were assessed for H. pylori Cag A protein expression and IL-8 induction in co-cultivation model with AGS cells.RESULTS Thirty point three percent of microbiologically confirmed H. pylori infected patients were seropositive for Cag A. Majority of H. pylori isolates were cag A gene positive(93.9%) with following vac A polymorphisms: 42.4% vac A s1m1, 23.2% s1m2 and 34.3% s2m2. Anti-Cag AIg G seropositivity was strongly associated with atrophic gastritis, increased mucosal inflammation according to the Sydney score, IL-8 and cag A m RNA expression. V a c A s a n d m p o l y m o r p h i s m s w e r e t h e m a j o r determinants for positive(vac A s1m1) or negative(vac A s2m2) anti-Cag A serological immune response, which also correlated with the in vitro inflammatory potential in AGS cells. In vitro co-cultivation of representative H. pylori strains with AGS cells confirmed functional Cag A translocation, which showed only partial correlation with Cag A seropositivity in patients, supporting vac A as major co-determinant of the immune response.CONCLUSION Serological immune response to H. pylori cag A + strain in H. pylori infected patients is strongly associated with vac A polymorphism, suggesting the crucial role of bacterial factors in immune and clinical phenotype of the infection. | Alexander Link Cosima Langner Wiebke Schirrmeister Wiebke Habendorf Jochen Weigt Marino Venerito Ina Tammer Dirk Schlüter Philipp Schlaermann Thomas F Meyer Thomas Wex Peter Malfertheiner | 2017 | World Journal of Gastroenterology2017，23，26： | 12 |
| 4 | Different antibiotic susceptibility between antrum and corpus of the stomach,a possible reason for treatment failure of Helicobacter pylori infection显示文摘AIM:To assess whether antibiotic resistance varies between the antrum and corpus of the stomach of patients that are either Helicobacter pylori(H.pylori)therapy-naive or pre-treated.METHODS:H.pylori strains were isolated from antrum and corpus biopsies from 66 patients that received a diagnostic gastroduodenoscopy for variant clinical indications.Antimicrobial susceptibility to amoxicillin,clarithromycin,tetracycline,metronidazole,levofloxacin and rifabutin was tested with the E-test method on IsoSensitest agar with 10 vol%defibrinated horse blood.In patients with a different antibiotic susceptibility pattern between the isolates from the antrum and corpus,DNA fingerprinting via random amplified polymorphic DNA analysis was performed to detect differences among DNA patterns of H.pylori isolates.RESULTS:Primary,secondary and tertiary resistance to clarithromycin was 6.9%,53.8%and 83.3%,retrospectively.Metronidazole and levofloxacin resistance also increased according to the number of previous treatments(17.2%,69.2%,83.3%;13.8%,23.1%,33.3%).Tertiary resistance to rifabutin was detected in12.5%of patients.In none of the 66 patients a resistance against amoxicillin or tetracycline was detectable.Discordant antibiotic susceptibility between antrum and corpus isolates for different antibiotics was seen in 15.2%(10/66)of the patients.Two out of those ten patients were naive to any H.pylori antibiotic treatment.The remaining eight patients previously received at least one eradication therapy.DNA fingerprinting analysis revealed no substantial differences among DNA patterns between antrum and corpus isolates in the majority of patients suggesting an infection with a single H.pylori strain.CONCLUSION:Different antibiotic susceptibility between antrum and corpus biopsies is a common phenomenon and a possible explanation for treatment failure.Resistant H.pylori strains may be missed if just one biopsy from one anatomic site of the stomach is taken for H.pylori susceptibility testing. | Michael Selgrad Ina Tammer Cosima Langner Jan Bornschein Julia Mei?le Arne Kandulski Mariya Varbanova Thomas Wex Dirk Schlüter Peter Malfertheiner | 2014 | World Journal of Gastroenterology2014，20，43： | 10 |

| 7 | CYLD deletion triggers nuclear factor-κB-signaling and increases cell death resistance in murine hepatocytes显示文摘AIM:To analyze the role of CYLD for receptor-mediated cell death of murine hepatocytes in acute liver injury models.METHODS:Hepatocyte cell death in CYLD knockout mice(CYLD-/-)was analyzed by application of liver injury models for CD95-(Jo2)and tumor necrosis factor(TNF)-α-[D-Gal N/lipopolysaccharide(LPS)]induced apoptosis.Liver injury was assessed by measurement of serum transaminases and histological analysis.Apoptosis induction was quantified by cleaved PARP staining and Western blotting of activated caspases.Nuclear factor(NF)-κB,ERK,Akt and jun amino-terminal kinases signaling were assessed.Primary Hepatocytes were isolated by two step-collagenase perfusion and treated with recombinant TNF-αand with the CD95-ligand Jo2.Cell viability was analyzed by MTT-assay.RESULTS:Livers of CYLD-/-mice showed increased anti-apoptotic NF-κB signaling.In both applied liver injury models CYLD-/-mice showed a significantly reduced apoptosis sensitivity.After D-Gal N/LPS treatment CYLD-/-mice exhibited significantly lower levels of alanine aminotransferase(ALT)(295 U/L vs 859 U/L,P<0.05)and aspartate aminotransferase(AST)(560 U/L vs 1025 U/L,P<0.01).After Jo injection CYLD-/-mice showed 2-fold lower ALT(50 U/L vs 110 U/L,P<0.01)and lower AST(250 U/L vs 435 U/L,P<0.01)serumlevels compared to WT mice.In addition,isolated CYLD-/-primary murine hepatocytes(PMH)were less sensitive towards death receptor-mediated apoptosis and showed increased levels of Bcl-2,XIAP,c IAP1/2,survivin and c-FLIP expression upon TNF-and CD95-receptor triggering,respectively.Inhibition of NF-κB activation by the inhibitor of NF-κB phosphorylation inhibitor BAY 11-7085 inhibited the expression of antiapoptotic proteins and re-sensitized CYLD-/-PMH towards TNF-and CD95-receptor mediated cell death.CONCLUSION:CYLD is a central regulator of apoptotic cell death in murine hepatocytes by controlling NF-κB dependent anti-apoptotic signaling. | Toni Urbanik Bruno Christian Koehler Laura Wolpert Christin Elbner Anna-Lena Scherr Thomas Longerich Nicole Kautz Stefan Welte Nadine Hovelmeyer Dirk Jager Ari Waisman Henning Schulze-Bergkamen | 2014 | World Journal of Gastroenterology2014，20，45： | 3 |

| 12 | Big Earth data:disruptive changes in Earth observation data management and analysis?显示文摘Turning Earth observation(EO)data consistently and systematically into valuable global information layers is an ongoing challenge for the EO community.Recently,the term‘big Earth data’emerged to describe massive EO datasets that confronts analysts and their traditional workflows with a range of challenges.We argue that the altered circumstances must be actively intercepted by an evolution of EO to revolutionise their application in various domains.The disruptive element is that analysts and end-users increasingly rely on Web-based workflows.In this contribution we study selected systems and portals,put them in the context of challenges and opportunities and highlight selected shortcomings and possible future developments that we consider relevant for the imminent uptake of big Earth data. | Martin Sudmanns Dirk Tiede Stefan Lang Helena Bergstedt Georg Trosta Hannah Augustin Andrea Baraldi Thomas Blaschke | 2020 | International Journal of Digital Earth2020，13，7： | 3 |

| 15 | Prospective observational multicenter study to define a diagnostic algorithm for biliary candidiasis显示文摘AIM:To develop an algorithm to improve the diagnosis and treatment of patients with biliary candidiasis.METHODS:We performed a prospective study of 127patients who underwent endoscopic retrograde cholangiopancreatography,for various biliary disorders,at 3 tertiary referral centers in Germany from July 2011through July 2012(ClinicalTrials.gov:NCT01109550).Bile,buccal,and stool samples were collected.When indicated,endoscopic transpapillary bile duct biopsies were performed to clarify the etiology of bile duct strictures and to prove invasive fungal infections.RESULTS:Candida species were detected in 38 of the 127 bile samples(29.9%).By multivariate analysis patients’age and previous endoscopic sphincterotomy were independent risk factors for biliary candidiasis(P<0.05).Patients with immunosuppression(P=0.058)and recent long-term antibiotic therapy(>7 d)(P=0.089)tend to be at risk for biliary candidiasis.One patient was negative in mycological culture of bile fluid but invasive biliary candidiasis was diagnosed histologically.Of Candida subspecies detected,36.7%were azole-resistant,such as C glabrata.Eight patients received anti-mycotic therapy,based on our algorithm.Of these,3 had cancer with biliary tract involvement,2had secondary sclerosing cholangitis,1 had retroperitoneal fibrosis,and 5 had septicemia.In all patients contamination was ruled out by smears of the endoscope channel.CONCLUSION:Gastroenterologists should be aware of frequent candida colonization in patients with cholangitis and biliary disorders.Our suggested algorithm facilitates the further clinical management. | Philipp Lenz Franziska Eckelskemper Thomas Erichsen Tim Lankisch Alexander Dechêne Gabriele Lubritz Frank Lenze Torsten Beyna Hansjorg Ullerich Andre Schmedt Dirk Domagk | 2014 | World Journal of Gastroenterology2014，20，34： | 2 |
