| 1 | EGFR and HER2 expression in advanced biliary tract cancer显示文摘AIM:To analyze the pathogenetic role and potential clinical usefulness of the epidermal growth factor receptor(EGFR)and the human epidermal growth factor receptor 2(HER2)in patients with advanced biliary tract cancer(BTC). METHODS:EGFR and HER2 expression was studied in biopsy samples from 124 patients(51%women; median age 64.8 years),with advanced BTC diagnosed between 1997 and 2004.Five micrometers sections of paraffin embedded tissue were examined by standard, FDA approved immunohistochemistry.Tumors with scores of 2+or 3+for HER2 expression on immunochemistry were additionally tested for HER2 gene amplification by fluorescence in situ hybridisation(FISH).RESULTS:34/124 patients(27.4%)had gallbladder cancer,47(37.9%)had intrahepatic BTC and 43(34.7%)had extrahepatic or perihilar BTC.EGFR expression was examined in a subset of 56 samples. EGFR expression was absent in 22/56 tumors(39.3%). Of the remaining samples expression was scored as 1+in 12(21.5%),2+in 13(23.2%)and 3+in 9(16%), respectively.HER2 expression was as follows:score 0 73/124(58.8%),score 1+27/124(21.8%),score 2+ 21/124(17%)and score 3+4/124(3.2%).HER2 gene amplification was present in 6/124,resulting in an overall amplification rate of 5%. CONCLUSION:Our data suggest that routine testing and therapeutic targeting of HER2 does not seem to be useful in patients with BTC,while targeting EGFR may be promising. | Jan Harder Oliver Waiz Florian Otto Michael Geissler Manfred Olschewski Brigitte Weinhold Hubert E Blum Annette Schmitt-Graeff Oliver G Opitz | 2009 | World Journal of Gastroenterology2009，15，36： | 18 |
| 2 | Molecular changes in hepatic metabolism and transport incirrhosis and their functional importance显示文摘Liver cirrhosis is the common endpoint of many hepatic diseases and represents a relevant risk for liver failure and hepatocellular carcinoma.The progress of liver fibrosis and cirrhosis is accompanied by deteriorating liver function.This review summarizes the regulatory and functional changes in phase Ⅰ and phaseⅡmetabolic enzymes as well as transport proteins and provides an overview regarding lipid and glucose metabolism in cirrhotic patients.Interestingly,phase Ⅰ enzymes are generally down regulated transcriptionally,while phaseⅡenzymes are mostly preserved transcriptionally but are reduced in their function.Transport proteins are regulated in a specific way that resembles the molecular changes observed in obstructive cholestasis.Lipid and glucose metabolism are characterized by insulin resistance and catabolism,leading to the disturbance of energy expenditure and wasting.Possible non-invasive tests,especially breath tests,for components of liver metabolism are discussed.The heterogeneity and complexity of changes in hepatic metabolism complicate the assessment of liver function in individual patients.Additionally,studies in humans are rare,and species differences preclude the transferability of data from rodents to humans.In clinical practice,some established global scores or criteria form the basis for the functional evaluation of patients with liver cirrhosis,but difficult treatment decisions such as selection for transplantation or resection require further research regarding the application of existing non-invasive tests and the development of more specific tests. | Christoph G Dietrich Oliver Götze Andreas Geier | 2016 | World Journal of Gastroenterology2016，22，1： | 10 |
| 3 | Sporadic versus hereditary gastrinomas of the duodenum and pancreas: Distinct clinico-pathological and epidemiological features显示文摘Gastrinomas are defined as gastrin secreting tumors that are associated with Zollinger-Ellison syndrome (ZES). ZES is characterized by elevated fasting gastrin serum levels, positive secretin stimulation test and clinical symptoms such as recurrent peptic ulcer disease, gastroesophageal re?ux disease and occasional diarrhea. Genetically, nonhereditary (sporadic) gastrinomas are distinguished from hereditary gastrinomas, which are associated with multiple endocrine neoplasia type 1 (MEN1) syndrome. In general, duodenal gastrinomas are small and solitary if they are sporadic and multiple as well as hereditary. The sporadic gastrinomas occur in the duodenum or in the pancreas while the hereditary gastrinomas almost all occur in the duodenum. Our series of 77 sporadic duodenal neuroendocrine tumors (NETs) includes 18 patients (23.4%) with gastrinomas and ZES. Of 535 sporadic NETs in the pancreas collected from the NET archives of the departments of pathology in Zürich, Switzerland, and Kiel, Germany, 24 patients (4.5%) suffered from sporadic pancreatic gastrinomas and ZES. These NETs have to be distinguished fromtumors with immunohistochemical positivity for gastrin but without evidence of ZES. An additional 19 patients suffered from MEN1 and ZES. These patients showed exclusively duodenal gastrinomas, but not pancreatic gastrinomas. The prognosis of sporadic and MEN1- associated duodenal gastrinomas is better than that of pancreatic gastrinomas, since they progress slowly to liver metastasis. In summary, sporadic and MEN1- associated gastrinomas in the duodenum and pancreas show different clinico-pathological and genetic features. The incidence of sporadic duodenal gastrin-producing tumors is increasing, possibly due to optimized diagnostic procedures. In contrast, pancreatic MEN1- associated gastrinomas seem to be extremely rare. A considerable subset of tumors with immunohistochemical expression of gastrin but without evidence of ZES should be designated as functionally inactive NETs expressing gastrin, but not as gastrinomas. | Martin Anlauf Nele Garbrecht Tobias Henopp Anja Schmitt Regina Schlenger Andreas Raffel Markus Krausch Oliver Gimm Claus F Eisenberger Wolfram T Knoefel Henning Dralle Paul Komminoth Philipp U Heitz Aurel Perren Günter Klppel | 2006 | World Journal of Gastroenterology2006，12，34： | 7 |

| 5 | Identification of osteopontin as the most consistently over-expressed gene in intrahepatic cholangiocarcinoma: Detection by oligonucleotide microarray and real-time PCR analysis显示文摘AIM: To investigate the molecular pathways involved in human cholangiocarcinogenesis by gene expression profiling. METHODS: Oligonucleotide arrays (Affymetrix U133A) were used to establish a specific gene expression profile of intrahepatic CCC in comparison to corresponding non- malignant liver tissue. To validate the expression values of the most overexpressed genes, RT-PCR experiments were performed. RESULTS: Five hundred and fifty-two statistically differentially expressed genes/ESTs (221 probes significantly up-regulated, 331 probes down-regulated; P < 0.05; fold change > 2; ≥ 70%) were identified. Using these data and two-dimensional cluster analysis,a specific gene expression profile was obtained allowing fast and reproducible differentiation of CCC, which was confirmed by supervised neuronal network modelling. The most consistently overexpressed gene (median fold change 33.5, significantly overexpressed in 100%) encoded osteopontin. Furthermore, an association of various genes with the histopathological grading could be demonstrated. CONCLUSION: A highly specific gene expression profile for intrahepatic CCC was identified, allowing for its fast and reproducible discrimination against non- malignant liver tissue and other liver masses. The most overexpressed gene in intrahepatic CCC was the gene encoding osteopontin. These data may lead to a better understanding of human cholangiocarcinogenesis. | Holger G Hass Oliver Nehls Juergen Jobst Andrea Frilling Ulrich Vogel Stephan Kaiser | 2008 | World Journal of Gastroenterology2008，14，16： | 4 |

| 8 | Severe infection with multidrug-resistant Salmonella choleraesuis in a young patient with primary sclerosing cholangitis显示文摘Massive global spread of multidrug-resistant(MDR) Salmonella spp. expressing extended-spectrum beta-lactamase(ESBL) and additional resistance to fluoroquinolones has often been attributed to high international mobility as well as excessive use of oral antibiotics in livestock farming. However, MDR Salmonella spp. have not been mentioned as a widespread pathogen in clinical settings so far. We demonstrate the case of a 25-year-old male with primary sclerosing cholangitis who tested positive for MDR Salmonella enterica serotype Choleraesuis expressing ESBL and fluoroquinolone resistance. The pathogen was supposedly acquired during a trip to Thailand, causing severe fever, cholangitis andpancreatitis. To our knowledge, this is the first report of Salmonella enterica serotype Choleraesuis in Europe expressing such a multidrug resistance pattern. ESBL resistance of Salmonella enterica spp. should be considered in patients with obstructive biliary tract pathology and travel history in endemic countries. | Philip G Ferstl Claudia Reinheimer Katalin Jozsa Stefan Zeuzem Volkhard AJ Kempf Oliver Waidmann Georgios Grammatikos | 2017 | World Journal of Gastroenterology2017，23，11： | 2 |
