| 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 |

| 4 | Influence of unrecorded alcohol consumption on liver cirrhosis mortality显示文摘Unrecorded alcohol includes illegally distributed alcohol as well as homemade or surrogate alcohol which is unintended for consumption by humans(e.g.,cosmetics containing alcohol).The highest unrecorded alcohol consumption occurs in Eastern Europe and some of these countries have an over proportional liver cirrhosis mortality.Compounds besides ethanol have been hypothesized as being responsible for this observation.On the other hand,chemical investigations were unable to prove that unrecorded alcohol regularly contains contaminants above toxicological thresholds.However,illegally produced spirits regularly contain higher percentages of alcohol(above 45%by volume),but for considerably less costs compared with licit beverages,potentially causing more problematic patterns of drinking.In this review,it is investigated whether patterns of drinking rather than product composition can explain the liver cirrhosis mortality rates.Statistical examination of World Health Organization country data shows that the originally detected correlation of the percentage of unrecorded alcohol consumption and liver cirrhosis mortality rates disappears when the data is adjusted for the prevalence of heavy episodic drinking.It may be concluded that there is currently a lack of data to demonstrate causality between the composition of illicit spirits(e.g.,higher levels of certain contaminants in home-produced products)and liver toxicity on a population scale.Exceptions may be cases of poisoning with antiseptic liquids containing compounds such as polyhexamethyleneguanidine,which were reported to be consumed as surrogate alcohol in Russia,leading to an outbreak of acute cholestatic liver injury,histologically different from conventional alcoholic liver disease. | Dirk W Lachenmeier Yulia B Monakhova Jürgen Rehm | 2014 | World Journal of Gastroenterology2014，20，23： | 10 |
| 5 | Palliative chemotherapy for gastroesophageal cancer in old and very old patients: A retrospective cohort study at the National Center for Tumor Diseases, Heidelberg显示文摘AIM:To investigate the outcome of palliative chemotherapy in old patients with gastroesophageal cancer at the National Center for Tumor Diseases,Heidelberg.METHODS:Using a prospectively generated database,we retrospectively analyzed 55 patients≥70years under palliative chemotherapy for advanced gastroesophageal cancer at the outpatient clinic of the National Center for Tumor Diseases Heidelberg,Germany between January 2006 and December2013.Further requirements for inclusion were(1)histologically proven diagnosis of gastroesophageal cancer;(2)advanced(metastatic or inoperable)disease;and(3)no history of radiation or radiochemotherapy.The clinical information included Eastern Cooperative Oncology Group performance status(ECOG PS),presence and site of metastases at diagnosis,date of previous surgery and perioperative chemotherapy,start and stop date of first-line treatment,toxicities and consecutive dosage reductions of first-line treatment,response to first-line therapy,date of progression,usage of second-line therapies and date and cause of death.Survival times[progression-free survival(PFS),overall survival(OS)and residual survival(RS)]were calculated.Toxicity and safety were examined.Prognostic factors including ECOG PS,age and previousperioperative treatment were analyzed.RESULTS:Median age of our cohort was 76 years.86%of patients received a combination of two cytotoxic drugs.76 percent of patients had an oxaliplatin-based first-line therapy with the oxaliplatin and 5-fluorouracil regimen being the predominantely chosen regimen(69%).Drug modifications due to toxicity were necessary in 56%of patients,and 11%of patients stopped treatment due to toxicities.Survival times of our cohort are in good accordance with the major phaseⅢtrials that included mostly younger patients:PFS and OS were 5.8 and 9.5 mo,respectively.Survival differed significantly between patient groups with low(≤1)and high(≥2)ECOG PS(12.7 mo vs 3.8 mo,P<0.001).Very old patients(≥75 years)did not show a worse outcome in terms of survival.Patients receiving secondline treatment(51%)had a significantly longer RS than patients with best supportive care(6.8 vs 1.4 mo,P=0.001).Initial ECOG PS was a strong prognostic factor for PFS,OS and RS.CONCLUSION:Old patients with non-curable gastroesophageal cancer should be offered chemotherapy,and ECOG PS is a tool for balancing benefit and harm upfront.Second-line treatment is reasonable. | Anne Katrin Berger Stefanie Zschaebitz Christine Komander Dirk Jger Georg Martin Haag | 2015 | World Journal of Gastroenterology2015，21，16： | 6 |
| 6 | Targeting cell death signaling in colorectal cancer:Current strategies and future perspectives显示文摘The evasion from controlled cell death induction has been considered as one of the hallmarks of cancer cells.Defects in cell death signaling are a fundamental phenomenon in colorectal cancer.Nearly any non-invasive cancer treatment finally aims to induce cell death.However,apoptosis resistance is the major cause for insufficient therapeutic success and disease relapse in gastrointestinal oncology.Various compounds have been developed and evaluated with the aim to meet with this obstacle by triggering cell death in cancer cells.The aim of this review is to illustrate current approaches and future directions in targeting cell death signaling in colorectal cancer.The complex signaling network of apoptosis will be demonstrated and the'druggability'of targets will be identified.In detail,proteins regulating mitochondrial cell death in colorectal cancer,such as Bcl-2 and survivin,will be discussed with respect to potential therapeutic exploitation.Death receptor signaling and targeting in colorectal cancer will be outlined.Encouraging clinical trials including cell death based targeted therapies for colorectal cancer are under way and will be demonstrated.Our conceptual understanding of cell death in cancer is rapidly emerging and new types of controlled cellular death have been identified.To meet this progress in cell death research,the implication of autophagy and necroptosis for colorectal carcinogenesis and therapeutic approaches will also be depicted.The main focus of this topic highlight will be on the revelation of the complex cell death concepts in colorectal cancer and the bridging from basic research to clinical use. | Bruno Christian Koehler Dirk Jger Henning Schulze-Bergkamen | 2014 | World Journal of Gastroenterology2014，20，8： | 4 |
| 7 | On tolerability and safety of a maintenance treatment with 6-thioguanine in azathioprineor 6-mercaptopurine intolerant IBD patients显示文摘AIM: To determine the tolerability and safety profile of a low-dose maintenance therapy with 6-TG in azathioprine (AZA) or 6-mercaptopurine (6-MP) intolerant inflammatory bowel disease (IBD) patients over a treatment period of at least 1 year.METHODS: Database analysis.RESULTS: Twenty out of ninety-five (21%) patients discontinued 6-TG (mean dose 24.6 mg; mean 6-TGN level 540 pmol/8×108 RBC) within 1 year. Reasons for discontinuation were GI complaints (31%), malaise (15%)and hepatotoxicity (15%). Hematological events occurred in three patients, one discontinued treatment. In the 6-TG-tolerant group, 9% (7/75) could be classified as hepatotoxicity. An abdominal ultrasound was performed in 54% of patients, one patient had splenomegaly.CONCLUSION: The majority of AZA or 6-MP-intolerant IBD patients (79%) is able to tolerate maintenance treatment with 6-TG (dosages between 0.3 and 0.4 mg/kg per d). 6-TG may still be considered as an escape maintenance immunosuppressant in this difficult to treat group of patients, taking into account potential toxicity and efficacy of other alternatives. The recently reported hepatotoxicity is worrisome and 6-TG should therefore be administered only in prospective trials. | Nanne KH de Boer Luc JJ Derijks Lennard PL Gilissen Daniel W Hommes Leopold GJB Engels Sybrand Y de Boer Gijsbertus den Hartog Piet M Hooymans Anja BU M(?)kelburg Barend D Westerveld Anton HJ Naber Chris JJ Mulder Dirk J de Jong | 2005 | World Journal of Gastroenterology2005，11，35： | 4 |

| 11 | Characterization of colloidal arsenic at two abandoned gold mine sites in Nova Scotia, Canada, using asymmetric flow-field flow fractionation-inductively coupled plasma mass spectrometry显示文摘Asymmetric flow-field flow fractionation-inductively-coupled plasma-mass spectrometry was used to determine whether colloidal arsenic(As) exists in soil pore water and soil extract samples at two arsenic-contaminated abandoned gold mines(Montague and Goldenville, Nova Scotia). Colloidal arsenic was found in 12 out of the 80 collected samples(= 15%), and was primarily associated with iron(Fe) in the encountered colloids. The molar Fe/As ratios indicate that the colloids in some samples appeared to be discrete iron–arsenic minerals, whereas in other samples, they were more consistent with As-rich iron(oxy)hydroxides. Up to three discrete size fractions of colloidal As were encountered in the samples, with mean colloid diameters between 6 and 14 nm. The pore water samples only contained one size fraction of As-bearing colloids(around 6 nm diameter), while larger As-bearing colloids were only encountered in soil extracts. | Kathryn J Tindale Pritesh J Patel Dirk Wallschlager | 2016 | Journal of Environmental Sciences2016，28，11： | 3 |

| 14 | Segregation-assisted spinodal and transient spinodal phase separation at grain boundaries显示文摘Segregation to grain boundaries affects their cohesion,corrosion,and embrittlement and plays a critical role in heterogeneous nucleation.In order to quantitatively study segregation and low-dimensional phase separation at grain boundaries,here,we apply a density-based phase-field model.The current model describes the grain-boundary thermodynamic properties based on available bulk thermodynamic data,while the grain-boundary-density profile is obtained using atomistic simulations.To benchmark the performance of the model,Mn grain-boundary segregation in the Fe–Mn system is studied.3D simulation results are compared against atom probe tomography measurements conducted for three alloy compositions.We show that a continuous increase in the alloy composition results in a discontinuous jump in the segregation isotherm.The jump corresponds to a spinodal phase separation at grain boundary.For alloy compositions above the jump,we reveal an interfacial transient spinodal phase separation.The transient spinodal phenomenon opens opportunities for knowledge-based microstructure design through the chemical manipulation of grain boundaries.The proposed density-based model provides a powerful tool to study thermodynamics and kinetics of segregation and phase changes at grain boundaries. | Reza Darvishi Kamachali Alisson Kwiatkowski da Silva Eunan McEniry Dirk Ponge Baptiste Gault Jörg Neugebauer Dierk Raabe | 2020 | npj Computational Materials2020，，1： | 2 |

| 18 | Linking molecular deadwood-inhabiting fungal diversity and community dynamics to ecosystem functions and processes in Central European forests显示文摘Fungi play vital roles in the decomposition of deadwood due to their secretion of various enzymes that break down plant cell-wall complexes.The compositions of woodinhabiting fungal(WIF)communities change over the course of the decomposition process as the remaining mass of wood decreases and both abiotic and biotic conditions of the wood significantly change.It is currently not resolved which substrate-related factors govern these changes in WIF communities and whether such changes influence the deadwood decomposition rate.Here we report a study on fungal richness and community structure in deadwood of Norway spruce and European beech in temperate forest ecosystems using 454 pyrosequencing.Our aims were to disentangle the factors that correspond to WIF community composition and to investigate the links between fungal richness,taxonomically-resolved fungal identity,and microbial-mediated ecosystem functions and processes by analyzing physico-chemical wood properties,lignin-modifying enzyme activities and wood decomposition rates.Unlike fungal richness,we found significant differences in community structure between deadwood of different tree species.The composition of WIF communities was related to the physico-chemical properties of the deadwood substrates.Decomposition rates and the activities of ligninmodifying enzymes were controlled by the succession of the fungal communities and competition scenarios rather than fungal OTU richness.Our results provide further insights into links between fungal community structure and microbialmediated ecosystem functions and processes. | Björn Hoppe Witoon Purahong Tesfaye Wubet Tiemo Kahl Jürgen Bauhus Tobias Arnstadt Martin Hofrichter François Buscot Dirk Krüger | 2016 | Fungal Diversity2016，，2： | 2 |
