| 1 | Response evaluation of chemotherapy in metastatic colorectal cancer by contrast enhanced ultrasound显示文摘AIM:To evaluate whether contrast enhanced ultrasound(CEUS) might also be used for response prediction and early response evaluation in patients receiving bevacizumab based chemotherapy for metastasized colorectal cancer.METHODS:Thirty consecutive patients with non primary resectable liver metastases from colorectal cancer underwent CEUS before treatment(CEUS date 1) and before the second(CEUS date 2) and fourth(CEUS date 3) cycle of bevacizumab based chemotherapy.Three parameters [PEAK,Time to peak(TTP) and RISE RATE]were correlated with radiological response.RESULTS:For neoadjuvant purpose a reduction of tumour mass was required to assume clinical response.Based on these response criteria there was a significant(P < 0.001) correlation in TTP between metastases of responders(9.08 s) and non-responders(14.76 s) archived on CEUS date 1.By calculating a standardized quotient(metastases divided by normal liver tissue) we were able to define a cut off,predicting response with a sensitivity of 92.3 % and a specificity of 100 %.To reflect a palliative intention only those patients with progressive disease were classified as non-responders.In this stetting TTP was also significantly(P < 0.01) different between responders and non-responders.In contrast,Peak and Rise rate did not show any significant difference between responder and non-responder.CONCLUSION:CEUS might serve as a surrogate marker to predict treatment response in patients with metastasized colorectal cancer who receive antiangiogenic therapy. | Ramin Schirin-Sokhan Ron Winograd Christoph Roderburg Jhenee Bubenzer Nicole Cabral do ó Dorothee Guggenberger Hartmut Hecker Christian Trautwein Jens J W Tischendorf | 2012 | World Journal of Gastroenterology2012，18，6： | 16 |
| 2 | Transforming growth factor-β1 induces intestinal myofibroblast differentiation and modulates their migration显示文摘AIM:To investigate the effects of transforming growth factorβ1(TGF-β1)on the differentiation of colonic lamina propria fibroblasts(CLPF)into myofibroblasts in vitro. METHODS:Primary CLPF cultures were incubated with TGF-β1 and analyzed for production ofα-smooth muscle actin(α-SMA),fibronectin(FN)and FN isoforms.Migration assays were performed in a modified 48-well Boyden chamber.Levels of total and phosphorylated focal adhesion kinase(FAK)in CLPF were analyzed after induction of migration.RESULTS:Incubation of CLPF with TGF-β1 for 2 d did not changeα-SMA levels,while TGF-β1 treatment for 6 d significantly increasedα-SMA production. Short term incubation(6 h)with TGF-β1 enhanced CLPF migration,while long term treatment(6 d)of CLPF with TGF-β1 reduced migration to 15%-37% compared to untreated cells.FN and FN isoform mRNA expression were increased after short term incubation with TGF-β1(2 d)in contrast to long term incubation with TGF-β1 for 6 d.After induction of migration, TGF-β1-preincubated CLPF showed higher amounts of FN and its isoforms and lower levels of total and phosphorylated FAK than untreated cells. CONCLUSION:Long term incubation of CLPF with TGF-β1 induced differentiation into myofibroblasts with enhancedα-SMA,reduced migratory potential and FAK phosphorylation,and increased FN production.In contrast,short term contact(6 h)of fibroblasts with TGF-β1 induced a dose-dependent increase of cell migration and FAK phosphorylation without induction ofα-SMA production. | Julia Brenmoehl Sandra Nicole Miller Claudia Hofmann Daniela Vogl Werner Falk Jrgen Schlmerich Gerhard Rogler | 2009 | World Journal of Gastroenterology2009，15，12： | 12 |

| 4 | Calcitriol analog ZK191784 ameliorates acute and chronic dextran sodium sulfate-induced colitis by modulation of intestinal dendritic cell numbers and phenotype显示文摘AIM: To investigate the effects of ZK1916784, a low calcemic analog of calcitriol on intestinal inflammation. METHODS: Acute and chronic colitis was induced by dextran sodium sulfate (DSS) according to standard procedures. Mice were treated intraperitoneally with ZK1916784 or placebo and colonic inflammation was evaluated. Cytokine production by mesenterial lymph node (MLN) cells was measured by ELISA. Immunohistochemistry was performed to detect intestinal dendritic cells (DCs) within the colonic tissue, and the effect of the calcitriol analog on DCs was investigated. RESULTS: Treatment with ZK191784 resulted in significant amelioration of disease with a reduced histological score in acute and chronic intestinal inflammation. In animals with acute DSS colitis, down- regulation of colonic inflammation was associated with a dramatic reduction in the secretion of the proinflammatory cytokine interferon (IFN)-γ and a significant increase in intereleukin (IL)-10 by MLN cells. Similarly, in chronic colitis, IL-10 expression in colonic tissue increased 1.4-fold when mice were treated with ZK191784, whereas expression of the Th1-specific transcription factor T-beta decreased by 81.6%. Lower numbers of infiltrating activated CD11c+ DCs were found in the colon in ZK191784-treated mice with acute DSScolitis, and secretion of proinflammatory cytokines by primary mucosal DCs was inhibited in the presence of the calcitriol analog. CONCLUSION: The calcitriol analog ZK191784 demonstrated significant anti-inflammatory properties in experimental colitis that were at least partially mediated by the immunosuppressive effects of the derivate on mucosal DCs. | Ulrike G Strauch Florian Obermeier Nicole Grunwald Nadja Dunger Heiko C Rath Jürgen Schlmerich A Steinmeyer U Zügel HH Herfarth | 2007 | World Journal of Gastroenterology2007，13，48： | 4 |
| 5 | Definition of colorectal anastomotic leakage: A consensus survey among Dutch and Chinese colorectal surgeons显示文摘AIM To determine the level of consensus on the definition of colorectal anastomotic leakage(CAL) among Dutch and Chinese colorectal surgeons.METHODS Dutch and Chinese colorectal surgeons were asked to partake in an online questionnaire. Consensus in the online questionnaire was defined as > 80% agreement between respondents on various statements regarding a general definition of CAL,and regarding clinical and radiological diagnosis of the complication.RESULTS Fifty-nine Dutch and 202 Chinese dedicated colorectal surgeons participated in the online survey. Consensus was found on only one of the proposed elements of a general definition of CAL in both countries: ‘extravasation of contrast medium after rectal enema on a CT scan'. Another two were found relevant according to Dutch surgeons: ‘necrosis of the anastomosis found during reoperation',and ‘a radiological collection treated with percutaneous drainage'. No consensus was found for all other proposed elements that may be included in a general definition.CONCLUSION There is no universally accepted definition of CAL in the Netherlands and China. Diagnosis of CAL based on clinical manifestations remains a point of discussion in both countries. Dutch surgeons are more likely to report ‘subclinical' leaks as CAL,which partly explains the higher reported Dutch CAL rates. | Stefanus J van Rooijen Audrey CHM Jongen Zhou-qiao Wu Jia-fu Ji Gerrit D Slooter Rudi MH Roumen Nicole D Bouvy | 2017 | World Journal of Gastroenterology2017，23，33： | 4 |
| 6 | Towards integrated surveillance-response systems for the prevention of future pandemics显示文摘Most human pathogens originate from non-human hosts and certain pathogens persist in animal reservoirs.The transmission of such pathogens to humans may lead to self-sustaining chains of transmission.These pathogens represent the highest risk for future pandemics.For their prevention,the transmission over the species barrier—although rare—should,by all means,be avoided.In the current COVID-19 pandemic,surprisingly though,most of the current research concentrates on the control by drugs and vaccines,while comparatively little scientific inquiry focuses on future prevention.Already in 2012,the World Bank recommended to engage in a systemic One Health approach for zoonoses control,considering integrated surveillance-response and control of human and animal diseases for primarily economic reasons.First examples,like integrated West Nile virus surveillance in mosquitos,wild birds,horses and humans in Italy show evidence of financial savings from a closer cooperation of human and animal health sectors.Provided a zoonotic origin can be ascertained for the COVID-19 pandemic,integrated wildlife,domestic animal and humans disease surveillance-response may contribute to prevent future outbreaks.In conclusion,the earlier a zoonotic pathogen can be detected in the environment,in wildlife or in domestic animals;and the better human,animal and environmental surveillance communicate with each other to prevent an outbreak,the lower are the cumulative costs. | Jakob Zinsstag Jürg Utzinger Nicole Probst-Hensch Lv Shan Xiao-Nong Zhou | 2020 | Infectious Diseases of Poverty2020，9，5： | 3 |
| 7 | Four new polyhydroxylated steroids from the South Sea sponge Plakortis sp.显示文摘Four new polyhydroxylated steroids plaksterols A–D(1–4), together with two known related steroids ergost-7,9(11),22-trien-3β,5α,6α-triol(5) and ergosta-6β-methoxy-7,22-diene-3β,5α-diol(6), were isolated from methanol extract of the South China Sea marine sponge Plakortis sp. Their structures were identified by spectroscopic analysis, including NMR, MS, and IR. The cytotoxicity of the polyhydroxylated steroids were evaluated, and compound 6 showed moderate inhibitory activities against K562, HL-60 and BEL-7402 cells. | WANG Kun-Ya LI Ping-Lin SUN Jing-Fan de Voogd Nicole J TANG Xu-Li LI Guo-Qiang | 2020 | Chinese Journal of Natural Medicines2020，18，11： | 3 |
| 8 | Consensus on the definition of colorectal anastomotic leakage: A modified Delphi study显示文摘BACKGROUND Despite the emerging knowledge about colorectal anastomotic leakage(CAL)through the increasing number of clinical and experimental studies, there is no generally accepted definition of CAL. Because of the wide variety of definitions used in literature, comparison of study outcomes and quality of care is complicated.AIM To reach consensus on the definition of CAL using a modified Delphi method.METHODS The RAND/UCLA appropriateness method was used. The expert panel consisted of international colorectal surgeons and researchers who had published three or more articles about CAL. The consensus process consisted of two online distributed questionnaires and a third round with a recommendation. In the questionnaires participants were asked to rate the appropriateness of statements using a 1-9 Likert scale. Consensus was defined as a panel median between 1-3 or 7-9 without disagreement. In the final round a recommendation was formed regarding the definition of CAL and the expert panel was asked if they agreed or disagreed.RESULTSTwenty-three authors participated in the first round and twenty-one finished the second round. After two rounds consensus was reached on 37 items(80%) in nine different categories. The International Study Group of Rectal Cancer definition is the most frequently advised general definition by our panel. Consensus was reached regarding the clinical symptoms of CAL, which serum markers contributes to the suspicion of CAL, which radiological and perioperative findings should be considered as CAL, which grading system is appropriate and if there should be a range of postoperative days in the definition. Eventually, 19 experts completed all three rounds of which 16(84%) agreed with our final recommendations for the definition of CAL.CONCLUSION A consensus-based recommendation for the definition of CAL was formed using our modified Delphi method that can be widely incorporated in the field. | Claire PM van Helsdingen Audrey CHM Jongen Wouter J de Jonge Nicole D Bouvy Joep PM Derikx | 2020 | World Journal of Gastroenterology2020，26，23： | 3 |
