| 1 | Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand?显示文摘Diffusion-weighted imaging (DWI) is one of the magnetic resonance imaging (MRI) sequences providing qualitative as well as quantitative information at a cellular level. It has been widely used for various applications in the central nervous system. Over the past decade, various extracranial applications of DWI have been increasingly explored, as it may detect changes even before signal alterations or morphological abnormalities become apparent on other pulse sequences. Initial results from abdominal MRI applications are promising, particularly in oncological settings and for the detection of abscesses. The purpose of this article is to describe the clinically relevant basic concepts of DWI, techniques to perform abdominal DWI, its analysis and applications in abdominal visceral MR imaging, in addition to a brief overview of whole body DWI MRI. | Ajaykumar C Morani Khaled M Elsayes Peter S Liu William J Weadock Janio Szklaruk Jonathan Russell Dillman Asra Khan Thomas L Chenevert Hero K Hussain | 2013 | World Journal of Radiology2013，5，3： | 12 |
| 2 | Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732). | Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco | 2012 | World Journal of Gastroenterology2012，18，26： | 6 |
| 3 | High-density SNP-based genetic maps for the parents of an outcrossed and a selfed tetraploid garden rose cross, inferred from admixed progeny using the 68k rose SNP array显示文摘Dense genetic maps create a base for QTL analysis of important traits and future implementation of marker-assisted breeding.In tetraploid rose,the existing linkage maps include<300 markers to cover 28 linkage groups(4 homologous sets of 7 chromosomes).Here we used the 68k WagRhSNP Axiom single-nucleotide polymorphism(SNP)array for rose,in combination with SNP dosage calling at the tetraploid level,to genotype offspring from the garden rose cultivar‘Red New Dawn’.The offspring proved to be not from a single bi-parental cross.In rose breeding,crosses with unintended parents occur regularly.We developed a strategy to separate progeny into putative populations,even while one of the parents was unknown,using principle component analysis on pairwise genetic distances based on sets of selected SNP markers that were homozygous,and therefore uninformative for one parent.One of the inferred populations was consistent with self-fertilization of‘Red New Dawn’.Subsequently,linkage maps were generated for a bi-parental and a self-pollinated population with‘Red New Dawn’as the common maternal parent.The densest map,for the selfed parent,had 1929 SNP markers on 25 linkage groups,covering 1765.5 cM at an average marker distance of 0.9 cM.Synteny with the strawberry(Fragaria vesca)genome was extensive.Rose ICM1 corresponded to F.vesca pseudochromosome 7(Fv7),ICM4 to Fv4,ICM5 to Fv3,ICM6 to Fv2 and ICM7 to Fv5.Rose ICM2 corresponded to parts of F.vesca pseudochromosomes 1 and 6,whereas ICM3 is syntenic to the remainder of Fv6. | Mirjana Vukosavljev Paul Arens Roeland E Voorrips Wendy P C van't Westende G D Esselink Peter M Bourke Peter Cox W Eric van de Weg Richard G F Visser Chris Maliepaard Marinus J M Smulders | 2016 | Horticulture Research2016，3，1： | 6 |
| 4 | Endoscopic closure of a gastrocolic fistula using the over-the-scope-clip-system显示文摘Gastrointestinal (GI) defects such as fistulas and leaks can be potentially closed endoscopically using hemo-clips and loops. However, hemoclips may not allow for closure of large defects and they do not exert enough tensile force to keep fibrotic defects larger than 5 mm approximated. Herein we present a case of successful endoscopic closure of a gastrocolic fistula in a severely malnourished patient with complex post-surgical upper GI anatomy. We strongly believe that this device is a major breakthrough for the management of various types of discontinuity defects or fistulas. In addition, we show the usefulness of placing a direct jejunostomy using the double balloon enteroscopy (DBE) technique during the same procedure. The concept of providing direct jejunal feedings while allowing for upper gas-trointestinal bowel rest to promote the healing of the minimally invasive endoscopic operation is novel. Thus, our case is unique and exemplifies the utility of mini-mally invasive endoscopic endoluminal surgery. | Klaus Mnkemüller Shajan Peter Basem Alkurdi Jayapal Ramesh Daniel Popa C Mel Wilcox | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，8： | 5 |
| 5 | Model combining pre-transplant tumor biomarkers and tumor size shows more utility in predicting hepatocellular carcinoma recurrence and survival than the BALAD models显示文摘AIM To assess the performance of BALAD, BALAD-2 and their component biomarkers in predicting outcome of hepatocellular carcinoma(HCC) patients after liver transplant.METHODS BALAD score and BALAD-2 class are derived from bilirubin, albumin, alpha-fetoprotein(AFP), Lens culinaris agglutinin-reactive AFP(AFP-L3), and des-gammacarboxyprothrombin(DCP). Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios(HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker-based to predictive models. RESULTS During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42(1.18-5.00), 1.86(0.98-3.52), and 2.83(1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48(1.15-1.91) and 1.59(1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45(1.06-1.98) and 1.38(1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65,0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant(S-LAD) demonstrated the highest predictive capability with c-statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION BALAD and BALAD-2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter(S-LAD). | Nicha Wongjarupong Gabriela M Negron-Ocasio Roongruedee Chaiteerakij Benyam D Addissie Essa A Mohamed Kristin C Mara William S Harmsen J Paul Theobald Brian E Peters Joseph G Balsanek Melissa M Ward Nasra H Giama Sudhakar K Venkatesh Denise M Harnois Michael R Charlton Hiroyuki Yamada Alicia Algeciras-Schimnich Melissa R Snyder Terry M Therneau Lewis R Roberts | 2018 | World Journal of Gastroenterology2018，24，12： | 5 |
| 6 | Argo floats revealing bimodality of large-scale mid-depth circulation in the North Atlantic显示文摘Analysis of Argo float trajectories at 1 000 m and temperature at 950 m in the North Atlantic between November 2003 and January 2005 demonstrates the existence of two different circulation modes with fast transition between them. Each mode has a pair of cyclonic-anticyclonic gyres. The difference is the location of the cyclonic gyre. The cyclonic gyre stretches from southeast to northwest in the first mode and from the southwest to the northeast in the second mode. The observed modes strongly affect the heat and salt transport in the North Atlantic. In particular, the second mode slows down the westward transport of the warm and saline water from the Mediterranean Sea. | CHU Peter C IVANOV Leonid M MELNICHENKO Oleg V LI Rongfeng | 2008 | Acta Oceanologica Sinica2008，27，2： | 4 |

| 9 | Coexpression of receptor-tyrosine-kinases in gastric adenocarcinoma-a rationale for a molecular targeting strategy?显示文摘AIM: To define the (co-)expression pattern of target receptor-tyrosine-kinases (RTK) in human gastric adenocarcinoma. METHODS: The (co-)expression pattern of VEGFR1-3,PDGFRα/b and EGFR1 was analyzed by RT-PCR in 51 human gastric adenocarcinomas. In addition,IHC staining was applied for confirmation of expression and analysis of RTK localisation. RESULTS: The majority of samples revealed a VEGFR1 (98%),VEGFR2 (80%),VEGFR3 (67%),PDGFRα (82%) and PDGFRβ(82%) expression,whereas only 62% exhibited an EGFR1 expression. 78% of cancers expressed at least four out of six RTKs. While VEGFR1-3 and PDGFRα revealed a predominantly cytoplasmatic staining in tumor cells,accompanied by an additional nuclear staining for VEGFR3 ,EGFR1 was almost exclusively detected on the membrane of tumor cells. PDGFRβ was restricted to stromal pericytes,which also depicted a PDGFRα expression.receptor-tyrosine-kinases coexpression in gastric adenocarcinoma and might therefore encourage an application of multiple-target RTK-inhibitors within a combination therapy. | Daniel Drescher Markus Moehler Ines Gockel Kirsten Frerichs Annett Müller Friedrich Dünschede Thomas Borschitz Stefan Biesterfeld Martin Holtmann Thomas Wehler Andreas Teufel Kerstin Herzer Thomas Fischer Martin R Berger Theodor Junginger Peter R Galle Carl C Schimanski | 2007 | World Journal of Gastroenterology2007，13，26： | 4 |
| 10 | 人体-座椅接触面测量参数的研究初探显示文摘文中介绍了一种集力、温度和湿度传感器信息的座椅舒适度检测系统。传感器的布放采用已发表文章中所介绍的布放方式:温度和湿度传感器分别放置在左、右腿和尾臀骨下方;4个力传感器分别放在左、右腿和左、右坐骨结节的下方。在进行人体实验前,对力、温度和湿度传感器的输出一致性进行了测试。测量数据显示:温度传感器标准方差为±0.2℃;湿度传感器标准方差为±0.3%,压力传感器标准方差为±0.09 V(其中加载负荷5 kg~15 kg,力传感器输出电压的变化为3.67~4.31 V),这表明所有的传感器具有一致的输出特性。在三天内,共有10人/次利用该检测系统对3种坐垫(泡沫、木质和压模坐垫)的舒适度进行了评估。为了避免次序效应对测量结果的影响,整个实验采用了拉丁方设计方法。通过将坐姿调整时间、最大温度和平均相对湿度与舒适度主观评测问卷进行对比分析,结果表明传感器的原始数据和相关参数的变化与人对座椅舒适度的主观评价之间存在一定的联系。 | 刘卓夫 罗中明 Vincenzo Cascioli Louise Mazzeo Andrewl Heusch Peter W M^c Carthy | 2011 | 仪表技术与传感器2011，，1： | 3 |
| 11 | Complementary roles of interventional radiology and therapeutic endoscopy in gastroenterology显示文摘Acute upper and lower gastrointestinal bleeding, enteral feeding, cecostomy tubes and luminal strictures are some of the common reasons for gastroenterology service. While surgery was initially considered the main treatment modality, the advent of both therapeutic endoscopy and interventional radiology have resulted in the paradigm shift in the management of these conditions. In this paper, we discuss the patient's work up, indications, and complementary roles of endoscopic and angiographic management in the settings of gastrointestinal bleeding, enteral feeding, cecostomy tube placement and luminal strictures. These conditions often require multidisciplinary approaches involving a team of interventional radiologists, gastroenterologists and surgeons. Further, the authors also aim to describe how the fields of interventional radiology and gastrointestinal endoscopy are overlapping and complementary in the management of these complex conditions. | David M Ray Indu Srinivasan Shou-jiang Tang Andreas S Vilmann Peter Vilmann Timothy C McCowan Akash M Patel | 2017 | World Journal of Radiology2017，9，3： | 2 |

| 14 | A next-generation marker genotyping platform(AmpSeq)in heterozygous crops:a case study for marker-assisted selection in grapevine显示文摘Marker-assisted selection(MAS)is often employed in crop breeding programs to accelerate and enhance cultivar development,via selection during the juvenile phase and parental selection prior to crossing.Next-generation sequencing and its derivative technologies have been used for genome-wide molecular marker discovery.To bridge the gap between marker development and MAS implementation,this study developed a novel practical strategy with a semi-automated pipeline that incorporates trait-associated single nucleotide polymorphism marker discovery,low-cost genotyping through amplicon sequencing(AmpSeq)and decision making.The results document the development of a MAS package derived from genotyping-by-sequencing using three traits(flower sex,disease resistance and acylated anthocyanins)in grapevine breeding.The vast majority of sequence reads(⩾99%)were from the targeted regions.Across 380 individuals and up to 31 amplicons sequenced in each lane of MiSeq data,most amplicons(83 to 87%)had<10%missing data,and read depth had a median of 220–244×.Several strengths of the AmpSeq platform that make this approach of broad interest in diverse crop species include accuracy,flexibility,speed,high-throughput,low-cost and easily automated analysis. | Shanshan Yang Jonathan Fresnedo-Ramíre Minghui Wang Linda Cote Peter Schweitzer Paola Barba Elizabeth M Takacs Matthew Clark James Luby David C Manns Gavin Sacks Anna Katharine Mansfield Jason Londo Anne Fennell David Gadoury Bruce Reisch Lance Cadle-Davidson Qi Sun | 2016 | Horticulture Research2016，3，1： | 2 |
