| 1 | Benign liver tumors in pediatric patients-Review with emphasis on imaging features显示文摘Benign hepatic tumors are commonly observed in adults,but rarely reported in children.The reasons for this remain speculative and the exact data concerning the incidence of these lesions are lacking.Benign hepatic tumors represent a diverse group of epithelial and mesenchymal tumors.In pediatric patients,most benign focal liver lesions are inborn and may grow like the rest of the body.Knowledge of pediatric liver diseases and their imaging appearances is essential in order to make an appropriate differential diagnosis.Selection of the appropriate imaging test is challenging,since it depends on a number of age-related factors.This paper will discuss the most frequently encountered benign liver tumors in children(infantile hepatic hemangioendothelioma,mesenchymal hamartoma,focal nodular hyperplasia,nodular regenerative hyperplasia,and hepatocellular adenoma),as well as a comparison to the current knowledge regarding such tumors in adult patients.The current emphasis is on imaging features,which are helpful not only for the initial diagnosis,but also for pre- and posttreatment evaluation and follow-up.In addition,future perspectives of contrast-enhanced ultrasound(CEUS) in pediatric patients are highlighted,with descriptions of enhancement patterns for each lesion being discussed.The role of advanced imaging tests such as CEUS and magnetic resonance imaging,which allow for non-invasive assessment of liver tumors,is of utmost importance in pediatric patients,especially when repeated imaging tests are needed and radiation exposure should be avoided. | Liliana Chiorean Xin-Wu Cui Andrea Tannapfel Doris Franke Martin Stenzel Wojciech Kosiak Dagmar Schreiber-Dietrich J?rg Jüngert Jian-Min Chang Christoph F Dietrich | 2015 | World Journal of Gastroenterology2015，21，28： | 16 |
| 2 | Ultrasonographic imaging of inflammatory bowel disease in pediatric patients显示文摘Inflammatory bowel disease(IBD) is one of the most common chronic gastrointestinal diseases in pediatric patients.Choosing the optimal imaging modality for the assessment of gastrointestinal disease in pediatric patients can be challenging.The invasiveness and patient acceptance,the radiation exposure and the quality performance of the diagnostic test need to be considered.By reviewing the literature regarding imaging in inflammatory bowel disease the value of ultrasound in the clinical management of pediatric patients is highlighted.Transabdominal ultrasound is a useful,noninvasive method for the initial diagnosis of IBD in children;it also provides guidance for therapeutic decisions and helps to characterize and predict the course of the disease in individual patients.Ultrasound techniques including color Doppler imaging and contrast-enhanced ultrasound are promising imaging tools to determine disease activity and complications.Comparative studies between different imaging methods are needed. | Liliana Chiorean Dagmar Schreiber-Dietrich Barbara Braden Xin-Wu Cui Reiner Buchhorn Jian-Min Chang Christoph F Dietrich | 2015 | World Journal of Gastroenterology2015，21，17： | 7 |
| 3 | How to perform gastrointestinal ultrasound: anatomy and normal findings显示文摘Gastrointestinal ultrasound is a practical, safe, cheap and reproducible diagnostic tool in inflammatorybowel disease gaining global prominence amongst clinicians. Understanding the embryological processes of the intestinal tract assists in the interpretation of abnormal sonographic findings. In general terms, the examination principally comprises interrogation of the colon, mesentery and small intestine using both lowfrequency and high-frequency probes. Interpretation of findings on GIUS includes assessment of bowel wall thickness, symmetry of this thickness, evidence of transmural changes, assessment of vascularity using Doppler imaging and assessment of other specific features including lymph nodes, mesentery and luminal motility. In addition to B-mode imaging, transperineal ultrasonography, elastography and contrast-enhanced ultrasonography are useful adjuncts. This supplement expands upon these features in more depth. | Nathan S S Atkinson Robert V Bryant Yi Dong Christian Maaser Torsten Kucharzik Giovanni Maconi Anil K Asthana Michael Blaivas Adrian Goudie Odd Helge Gilja Dieter Nuernberg Dagmar Schreiber-Dietrich Christoph F Dietrich | 2017 | World Journal of Gastroenterology2017，23，38： | 5 |
| 4 | Liver elastography, comments on EFSUMB elastography guidelines 2013显示文摘Recently the European Federation of Societies for Ultrasound in Medicine and Biology Guidelines and Recommendations have been published assessing the clinical use of ultrasound elastography.The document is intended to form a reference and to guide clinical users in a practical way.They give practical advice for the use and interpretation.Liver disease forms the largest section,reflecting published experience to date including evidence from meta-analyses with shear wave and strain elastography.In this review comments and illustrations on the guidelines are given. | Xin-Wu Cui Mireen Friedrich-Rust Chiara De Molo Andre Ignee Dagmar Schreiber-Dietrich Christoph F Dietrich | 2013 | World Journal of Gastroenterology2013，19，38： | 4 |

| 13 | 来源特异性颗粒物空气污染与高敏C-反应蛋白之间的相关性:局部交通和工业排放物显示文摘[背景]长期颗粒物空气污染(PM2.5和PM10)暴露和高交通负荷与全身性炎症标志物相关。流行病学调查主要集中于总PM,代表不同来源污染物的混合物。[目的]探讨来源特异的PM与高敏C-反应蛋白(hs-CRP,一种心血管疾病的独立预测因子)之间的相关性。[方法]采用Heinz Nixdorf回忆研究(Heinz Nixdorf Recall study)中第一次(2000—2003年)和第二次(2006—2008年)的检测数据。Heinz Nixdorf回忆研究是一项在德国进行的、以人群为基础的前瞻性队列研究,初始参加者为4 814人(45~75岁)。利用化学传输模型估计参加者的住宅局部交通和行业特异性细颗粒物(PM2.5)长期暴露的状况。使用线性混合模型,以参与者作为随机截距,来估计特定来源的PM与hs-CRP水平的自然对数变换值之间的关联,并设置年龄、性别、教育程度、体质指数、低和高密度脂蛋白胆固醇、吸烟变量、体力活动、季节、湿度和城市等因素的对照(总共8 204名观察对象)。[结果]总PM2.5每增加1μg/m3与血清hs-CRP浓度增加4.53%相关(95%CI:2.76%~6.33%)。交通和行业特异性的PM2.5增加1μg/m3分别与血清hs-CRP升高17.89%(95%CI:7.66%~29.09%)和7.96%(95%CI:3.45%~12.67%)相关。PM10具有相似的关联性。[结论]与总PM相比,长期局部交通特异性PM(PM2.5,PM10)暴露与全身性炎症反应的相关性更强。全身性炎症反应与局部行业特异性PM的关联比与总PM的关联稍强,但二者无显著性差异。 | Frauke Hennig Kateryna Fuks Susanne Moebus Gudrun Weinmayr Michael Memmesheimer Hermann Jakobs Martina Brocker-Preuss Dagmar Führer-Sakel Stefan Mohlenkamp Raimund Erbel Karl-Heinz Jockel Barbara Hoffmann | 2014 | 环境与职业医学2014，31，11： | 0 |
