| 7 | Liver-specific gene expression in mesenchymal stem cells is induced by liver cells显示文摘AIM: The origin of putative liver cells from distinct bone marrow stem cells, e.g. hematopoietic stem cells or multipotent adult progenitor cells was found in recent in vitro studies. Cell culture experiments revealed a key role of growth factors for the induction of liver-specific genes in stem cell cultures. We investigated the potential of rat mesenchymal stem cells (MSC) from bone marrow to differentiate into hepatocytic cells in vitro. Furthermore,we assessed the influence of cocultured liver cells on induction of liver-specific gene expression.METHODS: Mesenchymal stem cells were marked with green fluorescent protein (GFP) by retroviral gene transduction. Clonal marked MSC were either cultured under liver stimulating conditions using fibronectin-coated culture dishes and medium supplemented with SCF, HGF,EGF, and FGF-4 alone, or in presence of freshly isolated rat liver cells. Cells in cocultures were harvested and GFP+ or GFP- cells were separated using fluorescence activated cell sorting. RT-PCR analysis for the stem cell marker Thy1 and the hepatocytic markers CK-18, albumin, CK-19,and AFP was performed in the different cell populations.RESULTS: Under the specified culture conditions, rat MSC cocultured with liver cells expressed albumin-, CK-18,CK-19, and AFP-RNA over 3 weeks, whereas MSC cultured alone did not show liver specific gene expression.CONCLUSION: The results indicate that (1) rat MSC from bone marrow can differentiate towards hepatocytic lineage in vitro, and (2) that the microenvironment plays a decisive role for the induction of hepatic differentiation of rMSC. | Claudia Lange Philipp Bassler Michael V.

| 13 | Contrast-enhanced ultrasound of histologically proven hepatic epithelioid hemangioendothelioma显示文摘AIM: To analyze contrast-enhanced ultrasound(CEUS) features of histologically proven hepatic epithelioid hemangioendothelioma(HEHE) in comparison to other multilocular benign focal liver lesions(FLL).METHODS: Twenty-five patients with histologically proven HEHE and 45 patients with histologically proven multilocular benign FLL were retrospectively reviewed. Four radiologists assessed the CEUS enhancement pattern in consensus.RESULTS: HEHE manifested as a single(n = 3) or multinodular(n = 22) FLL. On CEUS, HEHE showed rim-like(18/25, 72%) or heterogeneous hyperenhancement(7/25, 28%) in the arterial phase and hypoenhancement(25/25, 100%) in the portal venous and late phases(PVLP), a sign of malignancy. Eighteen patients showed central unenhanced areas(18/25, 72%); in seven patients(7/25, 28%), more lesions were detected in the PVLP. In contrast, all patients with hemangioma and focal nodular hyperplasia showed hyperenhancement as the most distinctive feature(P < 0.01).CONCLUSION: CEUS allows for characterization of unequivocal FLL. By analyzing the hypoenhancement in the PVLP, CEUS can determine the malignant nature of HEHE. | Yi Dong Wen-Ping Wang Vito Cantisani Mirko D'Onofrio Andre Ignee Lorenzo Mulazzani Adrian Saftoiu Zeno Sparchez Ioan Sporea Christoph F Dietrich | 2016 | World Journal of Gastroenterology2016,22,19: | 21 |
| 14 | Artificial intelligence in medical imaging of the liver显示文摘Artificial intelligence(AI), particularly deep learning algorithms, is gaining extensive attention for its excellent performance in image-recognition tasks. They can automatically make a quantitative assessment of complex medical image characteristics and achieve an increased accuracy for diagnosis with higher efficiency. AI is widely used and getting increasingly popular in the medical imaging of the liver, including radiology, ultrasound, and nuclear medicine. AI can assist physicians to make more accurate and reproductive imaging diagnosis and also reduce the physicians' workload. This article illustrates basic technical knowledge about AI, including traditional machine learning and deep learning algorithms, especially convolutional neural networks, and their clinical application in the medical imaging of liver diseases, such as detecting and evaluating focal liver lesions, facilitating treatment, and predicting liver treatment response. We conclude that machine-assisted medical services will be a promising solution for future liver medical care. Lastly, we discuss the challenges and future directions of clinical application of deep learning techniques. | Li-Qiang Zhou Jia-Yu Wang Song-Yuan Yu Ge-Ge Wu Qi Wei You-Bin Deng Xing-Long Wu Xin-Wu Cui Christoph F Dietrich | 2019 | World Journal of Gastroenterology2019,25,6: | 21 |
| 15 | 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 |
| 16 | 藏毛窦发病率和远期复发率现况及其影响因素分析显示文摘目的调查德国部队中藏毛窦的发病率和术后远期复发率的现状及其发展变化趋势,分析不同手术治疗方法、体格状况和吸烟量等因素对藏毛窦的发病率和术后远期复发率的影响。方法对德国三家部队医院1980至1996年收治的所有藏毛窦患者的资料进行统计,随机抽取其中500例患者进行随访。结果德国部队中藏毛窦的发病率由1985年的0.3/1000上升到2007年的2.4/1000。随机抽取的500例患者中2例死亡,498例接受了随访。其术后复发率从1981年的33%,到1986年的23%,再到1996年的12%,呈明显下降趋势(P=0.01)。藏毛窦切除后行开放愈合的复发率为16.8%,显著低于行一期缝合的复发率31.0%(P〈0.01)。部队中人均体质量每十年增加1kg,德国国民人均体质量每十年增加1.9kg,但是体质量的增加与藏毛窦复发率之间无显著相关性(P=0.72)。每天吸烟20支以上者藏毛窦的复发率比吸烟≤20支者显著升高(P=0.015)。结论在藏毛窦的术后复发率下降,特别是切除后开放愈合的术后复发率下降的同时,藏毛窦的发病率上升了近十倍。 | Theo Evers Dietrich Doll Edouard Matevossian Sebastian Noe Konrad Neumann 李挥力 Norbert Huser Rainer Ludde Sebastian Hoffmann Bjorn Dirk Krapohl | 2011 | 中华外科杂志2011,49,9: | 14 |
| 17 | Commercially available probiotic drinks containing Lactobacillus casei DN-114001 reduce antibiotic-associated diarrhea显示文摘AIM:To investigate the effect of Lactobacillus-containing commercially available probiotic formulations in Germany during antibiotic treatment with an analysis of cost-efficiency.METHODS:In an observational study,we analyzed the frequency of bowel movements from 258 patients with infections in a primary care hospital in western Germany;107 of the patients were offered a probiotic drink containing at least 10 billion cultures of Lactobacillus casei DN 114001 b.i.d.The economic analysis was based on the costs of patient isolation vs preventive intake of probiotics.In a second pilot study,two commercially available probiotic drinks with different Lactobacillus casei strains were directly compared in 60patients in a randomized controlled fashion.RESULTS:In the first study,the incidence of antibioticassociated diarrhea(AAD)was significantly reducedin the intervention group(6.5%vs 28.4%),and the duration of AAD in days was significantly shorter(1.7±1.1 vs 3.1±2.1).Higher age and creatinine and lower albumin were identified as risk factors for AAD.Ampicillin was the antibiotic with the highest rate of AAD(50%)and with the greatest AAD reduction in the probiotic group(4.2%,relative risk reduction 92%).The economic analysis showed a cost advantage of nearly60000€/year in a department of this size.The second study confirmed the preventive effect of the drink with Lactobacillus casei DN114001;however,there were no advantages found for the other tested probiotic drink containing Lactobacillus casei Shirota.CONCLUSION:In contrast to a drink containing Lactobacillus casei Shirota,a commercially available probiotic drink containing Lactobacillus casei DN 114001 costefficiently reduces the prevalence of AAD during antibiotic treatment. | Christoph G Dietrich Tanja Kottmann Manuela Alavi | 2014 | World Journal of Gastroenterology2014,20,42: | 14 |
| 18 | Artificial intelligence in breast ultrasound显示文摘Artificial intelligence(AI) is gaining extensive attention for its excellent performance in image-recognition tasks and increasingly applied in breast ultrasound. AI can conduct a quantitative assessment by recognizing imaging information automatically and make more accurate and reproductive imaging diagnosis. Breast cancer is the most commonly diagnosed cancer in women,severely threatening women's health, the early screening of which is closely related to the prognosis of patients. Therefore, utilization of AI in breast cancer screening and detection is of great significance, which can not only save time for radiologists, but also make up for experience and skill deficiency on some beginners. This article illustrates the basic technical knowledge regarding AI in breast ultrasound, including early machine learning algorithms and deep learning algorithms, and their application in the differential diagnosis of benign and malignant masses. At last, we talk about the future perspectives of AI in breast ultrasound. | Ge-Ge Wu Li-Qiang Zhou Jian-Wei Xu Jia-Yu Wang Qi Wei You-Bin Deng Xin-Wu Cui Christoph F Dietrich | 2019 | World Journal of Radiology2019,11,2: | 12 |
| 19 | Endoscopic ultrasonography-guided endoscopic treatment of pancreatic pseudocysts and walled-off necrosis:New technical developments显示文摘In the last decades,the treatment of pancreatic pseudocysts and necrosis occurring in the clinical context of acute and chronic pancreatitis has shifted towards minimally invasive endoscopic interventions.Surgical procedures can be avoided in many cases by using endoscopically placed,Endoscopic ultrasonography-guided techniques and drainages.Endoscopic ultrasound enables the placement of transmural plastic and metal stents or nasocystic tubes for the drainage of peripancreatic fluid collections.The development of selfexpanding metal stents and exchange free delivering systems have simplified the drainage of pancreatic fluid collections.This review will discuss available therapeutic techniques and new developments. | Barbara Braden Christoph F Dietrich | 2014 | World Journal of Gastroenterology2014,20,43: | 12 |
| 20 | Contrast enhanced ultrasound of renal masses显示文摘Contrast enhanced ultrasound(CEUS) has gained clinical importance over the last years for the characterization of hepatic masses.Its role in extrahepatic indications has been investigated repeatedly but has been less comprehensively studied.Currently more than 50% of renal masses are incidentally diagnosed,mostly by B-mode ultrasound.The method of choice for characterization of renal lesions is contrast enhanced computed tomography(CECT).In the case of cystic lesions CECT refers to the Bosniak classification for cystic lesions to assess the risk of malignant behavior.The majority of masses are renal cell carcinoma,but the exact proportion is controversial.Disadvantages of CECT are a significant risk for patients with impaired renal function,allergic reactions and hyperthyroidism due to iodinated contrast agents.Several studies concerning CEUS for the characterization of both solid and cystic renal lesions have been published,but prospective multicenter studies are missing,the presented data being mainly descriptive.The aim of the this manuscript is to review the current literature for CEUS in renal masses,to summarize the available data and focus on possible concepts for studies in the future. | Andre Ignee Bad Mergentheim Gudrun Schuessler Christoph Frank Dietrich | 2010 | World Journal of Radiology2010,2,1: | 11 |
