| 1 | Multiphase computed tomography radiomics of pancreatic intraductal papillary mucinous neoplasms to predict malignancy显示文摘BACKGROUND Intraductal papillary mucinous neoplasms(IPMNs)are non-invasive pancreatic precursor lesions that can potentially develop into invasive pancreatic ductal adenocarcinoma.Currently,the International Consensus Guidelines(ICG)for IPMNs provides the basis for evaluating suspected IPMNs on computed tomography(CT)imaging.Despite using the ICG,it remains challenging to accurately predict whether IPMNs harbor high grade or invasive disease which would warrant surgical resection.A supplementary quantitative radiological tool,radiomics,may improve diagnostic accuracy of radiological evaluation of IPMNs.We hypothesized that using CT whole lesion radiomics features in conjunction with the ICG could improve the diagnostic accuracy of predicting IPMN histology.AIM To evaluate whole lesion CT radiomic analysis of IPMNs for predicting malignant histology compared to International Consensus Guidelines.METHODS Fifty-one subjects who had pancreatic surgical resection at our institution with histology demonstrating IPMN and available preoperative CT imaging were included in this retrospective cohort.Whole lesion semi-automated segmentation was performed on each preoperative CT using Healthmyne software(Healthmyne,Madison,WI).Thirty-nine relevant radiomic features were extracted from each lesion on each available contrast phase.Univariate analysis of the 39 radiomics features was performed for each contrast phase and values were compared between malignant and benign IPMN groups using logistic regression.Conventional quantitative and qualitative CT measurements were also compared between groups,viaχ2(categorical)and Mann Whitney U(continuous)variables.RESULTS Twenty-nine subjects(15 males,age 71±9 years)with high grade or invasive tumor histology comprised the'malignant'cohort,while 22 subjects(11 males,age 70±7 years)with low grade tumor histology were included in the'benign'cohort.Radiomic analysis showed 18/39 precontrast,19/39 arterial phase,and 21/39 venous phase features differentiated malignant from benign IPMNs(P<0.05).Multivariate analysis including only ICG criteria yielded two significant variables:thickened and enhancing cyst wall and enhancing mural nodule<5 mm with an AUC(95%CI)of 0.817(0.709-0.926).Multivariable post contrast radiomics achieved an AUC(95%CI)of 0.87(0.767-0.974)for a model including arterial phase radiomics features and 0.834(0.716-0.953)for a model including venous phase radiomics features.Combined multivariable model including conventional variables and arterial phase radiomics features achieved an AUC(95%CI)of 0.93(0.85-1.0)with a 5-fold cross validation AUC of 0.90.CONCLUSION Multi-phase CT radiomics evaluation could play a role in improving predictive capability in diagnosing malignancy in IPMNs.Future larger studies may help determine the clinical significance of our findings. | Stuart L Polk Jung W Choi Melissa J McGettigan Trevor Rose Abraham Ahmed Jongphil Kim Kun Jiang Yoganand Balagurunathan Jin Qi Paola T Farah Alisha Rathi Jennifer B Permuth Daniel Jeong | 2020 | World Journal of Gastroenterology2020，26，24： | 5 |
| 2 | Ron receptor-dependent gene regulation in a mouse model of endotoxin-induced acute liver failure显示文摘BACKGROUND:Prior experimentation has shown that loss of the tyrosine kinase(TK) signaling domain of the Ron receptor leads to marked hepatocyte protection in a model of lipopolysaccharideinduced acute liver failure(ALF) in D-galactosamine(GalN)sensitized mice.The aim of this study was to identify the role of Ron in the regulation of hepatic gene expression.METHODS:Microarray analyses were performed on liver RNA isolated sequentially from wild-type(WT) and TK-/mice during the progression of ALF.Gene array data were validated using Western and immunohistochemistry analyses as well as with ex vivo culture systems.RESULTS:At baseline,101 genes were differentially expressed between WT and TK-/-livers,which regulate processes involved in hypoxia,proliferation,apoptosis and metabolism.One hour after ALF induction,WT livers exhibited increased cytokine expression compared to TK-/-livers,and after 4 hours,an induction of suppressor of cytokine signaling(SOCS) genes as well as JAK-STAT pathway activation were prominent in TK-/livers compared to controls.CONCLUSION:Our studies suggest a novel hepato-protective mechanism in Ron TK-/-mice wherein increased and sustained SOCS production and JAK-STAT activation in the hepatocyte may inhibit the destructive proinflammatory milieu and promote survival factors which blunt hepatic death and the ensuing development of ALF. | Rishikesh M Kulkarni Louis W Kutcher William D Stuart Daniel J Carson Mike A Leonis Susan E Waltz | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，4： | 3 |
| 3 | Current endoscopic approach to indeterminate biliary strictures显示文摘Biliary strictures are considered indeterminate when basic work-up, including transabdominal imaging and endoscopic retrograde cholangiopancreatography with routine cytologic brushing, are non-diagnostic. Indeterminate biliary strictures can easily be mischaracterized which may dramatically affect patient's outcome. Early and accurate diagnosis of malignancy impacts not only a patient's candidacy for surgery, but also potential timely targeted chemotherapies. A significant portion of patients with indeterminate biliary strictures have benign disease and accurate diagnosis is, thus, paramount to avoid unnecessary surgery. Current sampling strategies have suboptimal accuracy for the diagnosis of malignancy. Emerging data on other diagnostic modalities, such as ancillary cytology techniques, single operator cholangioscopy, and endoscopic ultrasonography-guided fine needle aspiration, revealed promising results with much improved sensitivity. | David W Victor Stuart Sherman Tarkan Karakan Mouen A Khashab | 2012 | World Journal of Gastroenterology2012，18，43： | 3 |

| 5 | Hepatocellular carcinoma locoregional therapies:Outcomes and future horizons显示文摘Hepatocellular carcinoma(HCC)is the most common primary cancer of the liver and has an overall five-year survival rate of less than twenty percent.For patients with unresectable disease,evolving liver-directed locoregional therapies provide efficacious treatment across the spectrum of disease stages and via a variety of catheter-directed and percutaneous techniques.Goals of locoregional therapies in HCC may include curative intent in early-stage disease,bridging or downstaging to surgical resection or transplantation for early or intermediate-stage disease,and local disease control and palliation in advanced-stage disease.This review explores the outcomes of chemoembolization,bland embolization,radioembolization,and percutaneous ablative therapies.Attention is also given to prognostic factors related to each of the respective techniques,as well as future directions of locoregional therapies for HCC. | Mina S Makary Stuart Ramsell Eric Miller Eliza W Beal Joshua D Dowell | 2021 | World Journal of Gastroenterology2021，27，43： | 2 |
| 6 | Genetic and environmental control of fruit maturation,dry matter and firmness in apple(Malus×domestica Borkh.)显示文摘For any given genotype,the environment in which an apple is grown can influence the properties of the fruit considerably.While there has been extensive research on the mechanism of the genetic control of fruit quality traits,less effort has been made to investigate the way that these genetic mechanisms interact with the environment.To address this issue,we employed a large‘Royal Gala’בBraeburn’population of 572 seedlings replicated over sites in three climatically diverse apple-growing regions in New Zealand.Phenotyping for traits including fruit maturation timing,firmness and dry matter content was performed at each of these three sites for a single growing season(2011),and at two sites(Motueka and Hawke’s Bay)for two seasons(2009 and 2010).The phenotype data collected over 2 years at two sites enabled the detection of 190 quantitative trait loci(QTL)that controlled these traits regardless of year or growing location,as well as some chromosomal loci that influenced the traits in a single given environment or year.For those loci that were environmentally stable over three sites,there was an interdependency of fruit maturation date,dry matter content and storage potential within this population,with two regions on Linkage Groups(LGs)10 and 16 strongly contributing.If these loci were used in a marker-assisted selection programme to select for progeny bearing firmer fruit,this would have the unintentional consequence of selecting,high dry matter content,later maturing apples.In addition,a further 113 new QTLs with a smaller effect were identified,some of which were exhibited only in a single growing environment,demonstrating the underlying complexity of control of traits determining fruit quality,in addition to the need for being aware of environmental effects when developing new apple varieties. | David Chagne Daya Dayatilake Robert Diack Murray Oliver Hilary Ireland Amy Watson Susan E Gardiner Jason W Johnston Robert J Schaffer Stuart Tustin | 2014 | Horticulture Research2014，1，1： | 2 |
