2Petawatt and exawatt class lasers worldwide显示文摘In the 2015 review paper‘Petawatt Class Lasers Worldwide’a comprehensive overview of the current status of highpower facilities of>200 TW was presented.This was largely based on facility specifications,with some description of their uses,for instance in fundamental ultra-high-intensity interactions,secondary source generation,and inertial confinement fusion(ICF).With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification(CPA),which made these lasers possible,we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed.We are now in the era of multi-petawatt facilities coming online,with 100 PW lasers being proposed and even under construction.In addition to this there is a pull towards development of industrial and multi-disciplinary applications,which demands much higher repetition rates,delivering high-average powers with higher efficiencies and the use of alternative wavelengths:mid-IR facilities.So apart from a comprehensive update of the current global status,we want to look at what technologies are to be deployed to get to these new regimes,and some of the critical issues facing their development.Colin N.Danson Constantin Haefner Jake Bromage Thomas Butcher Jean-Christophe FChanteloup Enam A.Chowdhury Almantas Galvanauskas Leonida A.Gizzi Joachim Hein David I.Hillier Nicholas W.Hopps Yoshiaki Kato Efim A.Khazanov Ryosuke Kodama Georg Korn Ruxin Li Yutong Li Jens Limpert Jingui Ma Chang Hee Nam David Neely Dimitrios Papadopoulos Rory R.Penman Liejia Qian Jorge J.Rocca andrey A.Shaykin Craig W.Siders Christopher Spindloe Sándor Szatmári Raoul M.G.M.Trines Jianqiang Zhu Ping Zhu Jonathan D.Zuegel 2019High Power Laser Science and Engineering2019,7,3:33
3Benign 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 2015World Journal of Gastroenterology2015,21,28:16
4Endoscopic 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 2015World Journal of Gastroenterology2015,21,47:8
5Ultrasonographic 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 2015World Journal of Gastroenterology2015,21,17:7
6眼前节内眼手术应用5%吡咯烷酮碘两种不同用法的前瞻性随机化比较研究显示文摘目的:确定5%吡咯烷酮碘采用两种不同的方法(结膜囊滴两滴和10ml溶液穹窿结膜冲洗)对降低结膜囊菌群的功效。方法:在这项前瞻性对照实验中。将行眼前节手术的200只眼随机分为对照组和研究组。两组病例术前均给予氧氟沙星滴眼液局部点眼和5%吡咯烷酮碘眶周区域皮肤擦洗消毒。术前对照组眼结膜囊内给予2滴5%吡咯烷酮碘溶液,研究组眼用5%吡咯烷酮碘溶液冲洗穹窿结膜。分别于术前和术后4个时间点行结膜细菌培养。结果:研究组78只眼中20只眼(26%)术前结膜细菌培养阳性:对照组94只眼中40只眼(43%)为阳性(P=0.02)。手术结束时。研究组78只眼中14只眼(18%)、对照组94只眼中30只眼(32%)结膜细菌培养阳性(PP=0.05)。结论:手术时应用5%吡咯烷酮碘溶液冲洗穹窿结膜与结膜囊仅点入两滴相比。前者显著降低了结膜细菌培养阳性率。Herminia Mino de Kaspar Robert T.

8ICC density predicts bacterial overgrowth in a rat model of post-infectious IBS显示文摘AIM:To investigate the interstitial cells of Cajal(ICC) number using a new rat model.METHODS:Sprague-Dawley rats were assigned to two groups.The first group received gavage with Campylobacter jejuni(C.jejuni) 81-176.The second group was gavaged with placebo.Three months after clearance of Campylobacter from the stool,precise segments of duodenum,jejunum,and ileum were ligated in self-contained loops of bowel that were preserved in anaerobic bags.Deep muscular plexus ICC(DMP-ICC) were quantified by two blinded readers assessing the tissue in a random,coded order.The number of ICC per villus was compared among controls,Campylobacter recovered rats without small intestinal bacterial overgrowth(SIBO),and Campylobacter recovered rats with SIBO.RESULTS:Three months after recovery,27% of rats gavaged with C.jejuni had SIBO.The rats with SIBO had a lower number of DMP-ICC than controls in the jejunum and ileum.Additionally there appeared to be a density threshold of 0.12 DMP-ICC/villus that was associated with SIBO.If ileal density of DMP-ICC was < 0.12 ICC/villus,54% of rats had SIBO compared to 9% among ileal sections with > 0.12(P<0.05).If the density of ICC was < 0.12 DMP-ICC/villus in more than one location of the bowel,88% of these had SIBO compared to 6% in those who did not(P<0.001).CONCLUSION:In this post-infectious rat model,the development of SIBO appears to be associated with a reduction in DMP-ICC.Further study of this rat model might help understand the pathophysiology of postinfectious irritable bowel syndrome.Sam-Ryong Jee Walter Morales Kimberly Low Christopher Chang Amy Zhu Venkata Pokkunuri Soumya Chatterjee Edy Soffer Jeffrey L Conklin Mark Pimentel 2010World Journal of Gastroenterology2010,16,29:3

12Intravascular large B-cell lymphoma presenting with altered mental status: A case report显示文摘BACKGROUND Intravascular large B-cell lymphoma(IVLBCL)is a rare and aggressive subtype of non-Hodgkin lymphoma with a varied presentation and no pathognomonic findings.Early diagnosis is critical to altering the disease course as early treatment with chemoimmunotherapy is required to prevent a rapidly fatal outcome.Strategies including improved awareness of this clinical entity through publication of cases with unique presentations are essential to prompt consideration of IVLBCL early in the disease workup.Here,we present a case of IVLBCL presenting with altered mental status and systemic organ dysfunction.CASE SUMMARY A 61-year-old male patient presented with flu-like symptoms and a high fever.He experienced rapid clinical deterioration with liver,kidney failure,and shock despite rapid antibiotic administration and supportive care.A broad infectious workup was negative.Intracranial imaging revealed nonspecific changes to the corpus callosum suspicious for vasculitis.Renal biopsy was non-diagnostic.After further progression of his symptoms,the family elected to withdraw care and the patient died shortly thereafter.Post-mortem analysis revealed clear multi-organ involvement by IVLBCL,prompting re-examination of the ante-mortem renal biopsy that also identified IVLBCL involvement.CONCLUSION IVLBCL is a rare disease.Communication with specialties and early biopsy is critical to establishing the diagnosis and initiating therapy.Christopher Robert D’Angelo Kimberly Ku Jessica Gulliver Julie Chang 2019World Journal of Clinical Oncology2019,10,12:2
13Comprehensive review of autoantibodies in patients with hyper-IgM syndrome显示文摘Hyper-immunoglobulin M syndrome is an X-linked primary immunodeficiency disease caused by mutations in the CD40 ligand gene.The CD40 ligand has been recently highlighted as playing a key role in the pathogenesis of primary biliary cholangitis.In the present study,we assessed an extensive set of serum autoantibodies in a series of well-defined patients with hyper-immunoglobulin M syndrome.Serum,liver-related and liver-not-related autoantibodies IgG,IgM and IgA were tested by ELISA and standard indirect immunofluorescence in HEp-2 cells in 13 Tunisian patients(8 males and 5 females,aged 1–12 years)with hyper-immunoglobulin M syndrome during 1995–2012 and,as controls,21 age-and gender-matched blood donors.The level of IgM antibody against MIT3 was significantly higher in patients than in controls(35.8 vs 10.7,P=0.002).Half of the hyperimmunoglobulin M syndrome patients were found to be anti-MIT3 IgM positive vs none of the controls(Po0.0001).Twenty-three percent of patients were found to be anti-sp100 antibody positive vs only 0.05%of controls.By immunofluorescence,92.3%of patients were MIT3 IgM positive vs none of the controls.In conclusion,the IgM class of anti-MIT3 antibodies was shown to be present by both ELISA and immunofluorescence in most of the patients with hyper-immunoglobulin M syndrome.The presence of the hallmark of primary biliary cholangitis,a disease where the CD40 ligand is a key player,in an immunodeficiency disease caused by mutations in the CD40 ligand gene is very intriguing and opens new scenarios in understanding the immune pathogenesis of primary biliary cholangitis.Mohamed-Ridha Barbouche Qubo Chen Marco Carbone Imen Ben-Mustapha Zakera Shums Mehdi Trifa Federica Malinverno Francesca Bernuzzi Haiyan Zhang Nourhen Agrebi Gary L Norman Christopher Chang M Eric Gershwin Pietro Invernizzi 2018Cellular & Molecular Immunology2018,15,6:2
