| 1 | Lower Bifidobacteria counts in both duodenal mucosa-associated and fecal microbiota in irritable bowel syndrome patients显示文摘AIM: To determine the composition of both fecal and duodenal mucosa-associated microbiota in irritable bowel syndrome (IBS) patients and healthy subjects using molecular-based techniques. METHODS: Fecal and duodenal mucosa brush samples were obtained from 41 IBS patients and 26 healthy subjects. Fecal samples were analyzed for the composition of the total microbiota using fluorescent in situ hybridization (FISH) and both fecal and duodenal brush samples were analyzed for the composition of bif idobacteria using real-time polymerase chain reaction. RESULTS: The FISH analysis of fecal samples revealed a 2-fold decrease in the level of bifidobacteria (4.2 ± 1.3 vs 8.3 ± 1.9, P < 0.01) in IBS patients compared to healthy subjects, whereas no major differences in other bacterial groups were observed. At the species level, Bifidobacterium catenulatum levels were significantly lower (6 ± 0.6 vs 19 ± 2.5, P < 0.001) in the IBS patients in both fecal and duodenal brush samples than in healthy subjects.CONCLUSION: Decreased bifidobacteria levels in both fecal and duodenal brush samples of IBS patients compared to healthy subjects indicate a role for microbiotic composition in IBS pathophysiology. | Angèle PM Kerckhoffs Melvin Samsom Michel E van der Rest Joris de Vogel Jan Knol Kaouther Ben-Amor Louis MA Akkermans | 2009 | World Journal of Gastroenterology2009,15,23: | 33 |

| 3 | 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 |
| 4 | 三江源和祁连山国家公园雪豹种群的遗传结构分析显示文摘掌握遗传信息对濒危物种的保护和管理具有重要意义。本研究在我国雪豹重要分布区祁连山和三江源国家公园分别采集粪便样品,利用mtDNA的cyt b基因、微卫星多态性位点进行了雪豹的物种鉴定、个体识别和种群遗传结构评估。在采集286份疑似雪豹粪便样品中,成功的对86份雪豹样品进行了扩增鉴定,利用微卫星位点进行个体识别获得41只雪豹个体,其中祁连山国家公园26只,三江源国家公园15只。通过等位基因数、有效等位基因数、观测杂合度、期望杂合度、多态信息含量等指标进行种群遗传多样性评估,认为雪豹种群遗传多样性相对较低,但祁连山国家公园雪豹种群遗传多样性相对较高。STRUCTURE进行群体遗传结构分析表明,4个种群可以划分为3个遗传类群,祁连山国家公园的种群(YCW和QLS)与三江源国家公园种群(DC和SJ)的遗传差异,可能与种群间的地理隔离存在明显的相似性。 | 张于光 Charlotte Hacker 张宇 薛亚东 乌力吉 代云川 罗平 谢然尼玛 Jan E Janecka 李迪强 | 2019 | 兽类学报2019,39,4: | 8 |
| 5 | Circulating inflammatory factors associated with worse long-term prognosis in colorectal cancer显示文摘AIM To investigate association of circulating inflammatory factors at the time of colorectal cancer(CRC) surgery with survival.METHODS Plasma levels from 174 CRC patients(69 females and 105 men), with median age 70 years(range 29-90), localized in the colon(n = 105) or rectum(n = 69), with stage Ⅰ(n = 24), stage Ⅱ(n = 54), stage Ⅲ(n = 67) and stage Ⅳ(n = 29) were measured using commercially available Bio-Plex Pro? Human Chemokine Panel 40-Plex, including 40 different chemokines, cytokines and interleukins. The prognostic association of each inflammatory factor was analysed as CRC-specific and total mortality.RESULTS Out of 174 patients, 66 died during the follow-up, 40 because of CRC specific mortality. High tertile levels of 8 factors were significantly associated with increased CRC-specific mortality, of which CCL1, CCL20, CCL24, CX3CL1, IL-4 and TNF-α remained significant in a multivariate Cox regression analysis. High tertile levels of 14 factors were associated with increased total mortality, of which CCL1, CCL15, CCL20, CX3CL1, CXCL13, IFN-γ, IL-2, IL-4 and IL-10 remained significant after adjustment for clinical covariates. For most of the inflammatory factors the association between higher tertile levels and an increased mortality in general appeared two years after surgery. High tertile levels of TNF-α and CCL24 were exclusively associated with CRC-specific mortality. The distribution of these factors were not associated with TNM stage with exception for CCL20.CONCLUSION High plasma levels of inflammatory factors are associated with increased risk of mortality among CRC patients and could be potential biomarkers for revealing prognosis. | Renate S Olsen Johnny Nijm Roland E Andersson Jan Dimberg Dick Wagsater | 2017 | World Journal of Gastroenterology2017,23,34: | 8 |

| 7 | Effects of cereal fiber on bowel function: A systematic review of intervention trials显示文摘AIM: To comprehensively review and quantitatively summarize results from intervention studies that examined the effects of intact cereal dietary fiber on parameters of bowel function. METHODS: A systematic literature search was conducted using Pub Med and EMBASE. Supplementary literature searches included screening reference lists from relevant studies and reviews. Eligible outcomes were stool wet and dry weight, percentage water in stools, stool frequency and consistency, and total transit time. Weighted regression analyses generated mean change(± SD) in these measures per g/d of dietary fiber. RESULTS: Sixty-five intervention studies among generally healthy populations were identified. A quantitative examination of the effects of non-wheat sources of intact cereal dietary fibers was not possible due to an insufficient number of studies. Weighted regression analyses demonstrated that each extra g/d of wheat fiber increased total stool weight by 3.7 ± 0.09 g/d(P < 0.0001; 95%CI: 3.50-3.84), dry stool weight by 0.75 ± 0.03 g/d(P < 0.0001; 95%CI: 0.69-0.82), and stool frequency by 0.004 ± 0.002 times/d(P = 0.0346; 95%CI: 0.0003-0.0078). Transittime decreased by 0.78 ± 0.13 h per additional g/d(P < 0.0001; 95%CI: 0.53-1.04) of wheat fiber among those with an initial transit time greater than 48 h.CONCLUSION: Wheat dietary fiber, and predominately wheat bran dietary fiber, improves measures of bowel function. | Jan de Vries Paige E Miller Kristin Verbeke | 2015 | World Journal of Gastroenterology2015,21,29: | 5 |

| 9 | A post-classical theory of enamel biomineralization… and why we need one显示文摘Enamel crystals are unique in shape,orientation and organization.They are hundreds of thousands times longer than they are wide,run parallel to each other,are oriented with respect to the ameloblast membrane at the mineralization front and are organized into rod or interrod enamel.The classical theory of amelogenesis postulates that extracellular matrix proteins shape crystallites by specifically inhibiting ion deposition on the crystal sides,orient them by binding multiple crystallites and establish higher levels of crystal organization.Elements of the classical theory are supported in principle by in vitro studies;however,the classical theory does not explain how enamel forms in vivo.In this review,we describe how amelogenesis is highly integrated with ameloblast cell activities and how the shape,orientation and organization of enamel mineral ribbons are established by a mineralization front apparatus along the secretory surface of the ameloblast cell membrane. | James P Simmer Amelia S Richardson Yuan-Yuan Hu Charles E Smith Jan Ching-Chun Hu | 2012 | International Journal of Oral Science2012,4,3: | 4 |

| 13 | Introduction of laparoscopic gastrectomy for gastric cancer in a Western tertiary referral centre:A prospective cost analysis during the learning curve显示文摘AIM To evaluate the costs of the introduction of a laparoscopic surgery program for gastric cancer in a Western community training hospital and tertiary referral centre for gastric cancer surgery. METHODS All patients who underwent surgery for gastric cancer with curative intent in 2013 and 2014 were prospectively included. Primary outcomes were costs regarding surgery and hospital stay. RESULTS Laparoscopic gastrectomy was used in 52 patients [mean age 68 years(± 9, range 50 to 87) years] and open gastrectomy was used in 25 patients [mean age 70 years(± 10, range 46 to 85)]. Mean costs(in euro's) of surgical instrumentation were significantly higher for laparo-scopic surgery: 2270 ± 670 vs 1181 ± 680 in the open approach(P < 0.001). Costs of theatre use were higher in the laparoscopic group: mean 3818 ± 865 vs 2545± 1268 in the open surgery(P < 0.001). Total costs of hospitalization(i.e., costs of surgery and admission)were not different between laparoscopic and open surgery, 8187 ± 4864 and 6152 ± 2680 respectively(P= 0.729). Mean length of hospital stay was 9 ± 12 d in the laparoscopic group vs 14 ± 14 d in the open group(P= 0.044). CONCLUSION The introduction of laparoscopic gastrectomy for gastric cancer coincided with higher costs for theatre use and surgical instrumentation compared to the open technique. Total costs were not significantly different due to shorter length of stay and less intensive care unit(ICU) admissions and shorter ICU stay in the laparoscopic group. | Juul J Tegels Charlotte E Silvius Frederique E Spauwen Karel W Hulsewé Anton G Hoofwijk Jan H Stoot | 2017 | World Journal of Gastrointestinal Oncology2017,9,5: | 2 |

| 15 | Association of gene and protein expression and genetic polymorphism of CC chemokine ligand 4 in colorectal cancer显示文摘BACKGROUND Leukocytes,such as T cells and macrophages,play an important role in tumorigenesis.CC chemokine ligand(CCL)4,which is produced by lymphocytes and macrophages,has been found to be expressed in the mucosa of the gastrointestinal tract and is a potent chemoattractant for various leukocytes.AIM To examine CCL4 expression and its genetic polymorphism rs10491121 in patients with colorectal cancer(CRC)and evaluate their prognostic significance.METHODS Luminex technology was used to determine CCL4 Levels in CRC tissue(n=98),compared with paired normal tissue,and in plasma from patients with CRC(n=103),compared with healthy controls(n=97).Included patients had undergone surgical resection for primary colorectal adenocarcinomas between 1996 and 2019 at the Department of Surgery,Ryhov County Hospital,Jönköping,Sweden.Reverse transcription quantitative PCR was used to investigate the CCL4 gene expression in CRC tissue(n=101).Paired normal tissue and TaqMan single nucleotide polymorphism assays were used for the CCL4 rs10491121 polymorphism in 610 CRC patients and 409 healthy controls.RESULTS The CCL4 protein and messenger RNA expression levels were higher in CRC tissue than in normal paired tissue(90%,P<0.001 and 45%,P<0.05,respectively).CRC tissue from patients with localized disease had 2.8-fold higher protein expression levels than that from patients with disseminated disease.Low CCL4 protein expression levels in CRC tissue were associated with a 30%lower cancer-specific survival rate in patients(P<0.01).The level of plasma CCL4 was 11%higher in CRC patients than in healthy controls(P<0.05)and was positively correlated(r=0.56,P<0.01)with the CCL4 protein level in CRC tissue.The analysis of CCL4 gene polymorphism rs10491121 showed a difference(P<0.05)between localized disease and disseminated disease in the right colon,with a dominance of allele A in localized disease.Moreover,the rate of the A allele was higher among CRC patients with mucinous cancer than among those with nonmucinous cancer.CONCLUSION The present study indicates that the CRC tissue levels of CCL4 and CCL4 gene polymorphism rs10491121,particularly in the right colon,are associated with clinical outcome in CRC patients. | Levar Shamoun Kalle Landerholm Amanda Balboa Ramilo Roland E Andersson Jan Dimberg Dick Wågsäter | 2021 | World Journal of Gastroenterology2021,27,30: | 2 |
