| 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 | Endoscopic ultrasound elastography: current status and future perspectives显示文摘Elastography is a new ultrasound modality that provides images and measurements related to tissue stiffness. Endoscopic ultrasound(EUS) has played an important role in the diagnosis and management of numerous abdominal and mediastinal diseases. Elastography by means of EUS examination can assess the elasticity of tumors in the proximity of the digestive tract that are hard to reach with conventional transcutaneous ultrasound probes, such as pancreatic masses and mediastinal or abdominal lymph nodes, thus improving the diagnostic yield of the procedure. Results from previous studies have promised benefits for EUS elastography in the differential diagnosis of lymph nodes, as well as for assessing masses with pancreatic or gastrointestinal(GI) tract locations. It is important to mention that EUS elastography is not considered a modality that can replace biopsy. However, it may be a useful adjunct, improving the accuracy of EUSfine needle aspiration biopsy(EUS-FNAB) by selecting the most suspicious area to be targeted. Even more, it may be useful for guiding further clinical management when EUS-FNAB is negative or inconclusive. In the present paper we will discuss the current knowledge of EUS elastography, including the technical aspects, along with its applications in the differential diagnosis between benign and malignant solid pancreatic masses and lymph nodes, as well as its aid in the differentiation between normal pancreatic tissues and chronic pancreatitis. Moreover, the emergent indication and future perspectives are summarized, such as the benefit of EUS elastography in EUS-guided fine needle aspiration biopsy, and its uses for characterization of lesions in liver, biliary tract, adrenal glands and GI tract. | Xin-Wu Cui Jian-Min Chang Quan-Cheng Kan Liliana Chiorean Andre Ignee Christoph F Dietrich | 2015 | World Journal of Gastroenterology2015，21，47： | 8 |
| 3 | 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 |
| 4 | Research on Benefit Distribution Mechanism of Farmers’ Specialized Cooperative Economic Organization显示文摘On the basis of conducting survey in Jiaonan City,the thesis analyzes benefit distribution mechanism of farmers’ specialized cooperative economic organizations:firstly,the benefit correlation is mainly the contract correlation;secondly,the profit distribution is mainly the dividend;thirdly,patronage refund has many connotations;fourthly,the public accumulation has not yet been quantified to individual;fifthly,the government support capital is ill-defined.Based on these,the measures are put forward in order to improve benefit distribution pattern of farmers’ specialized cooperative economic organizations:firstly,reform structure of property rights and realize farmers’ ownership;secondly,change mode of decision-making,and realize farmers’ control;thirdly,increase turnover rebate and realize farmers’ benefiting;fourthly,quantify public accumulation and government support fund. | SUN Hao-jie1,WANG Zheng-bing2,WANG Yun-hui3 1.School of Economics and Management,Chang’ an University,Xi’an 710064,China 2.College of Economics and Management,Northwest A & F University,Yangling 712100,China 3.Publicity Office of Party Committee,Xi’an Branch of the People’ Bank of China,Xi’an 710064,China | 2011 | Asian Agricultural Research2011，3，4： | 5 |
