1皮质下小血管病诊断的共识声明显示文摘血管性认知损害是用于描述一组涉及大血管和小血管的散发性和遗传性异质性疾病的诊断术语。皮质下小血管病可导致腔隙性梗死和进行性白质损害。被称为宾斯旺格病(Binswanger's disease, BD)的进行性白质损害患者构成了从单纯血管性疾病到合并神经变性病变的疾病谱。BD患者是一个相对同质性的亚组,存在缺氧缺血、腔隙性梗死和炎症,它们协同作用破坏血脑屏障和髓鞘。通过临床、脑脊液、神经心理学和影像学检查获得的多模式疾病标记物能促进该亚组患者的鉴别。本共识声明确定了一系列基于基础病理学改变的潜在生物学标记物,这将有助于诊断以及将来协作性治疗试验的患者选择。Gary A Rosenberg Anders Wallin Joanna M Wardlaw Hugh S Markus Joan Montaner Leslie Wolfson Costantino Iadecola Berislav V Zlokovic Anne Joutel Martin Dichgans Marco Duering Reinhold Schmidt Amos D Korczyn Lea T Grinberg Helena C Chui Vladimir Hachinski 王训师 张劼 陈涵丰 俞娅美 徐子奇 罗本燕 2016国际脑血管病杂志2016,24,6:18
2Radiofrequency ablation for treatment of hypersplenism: A feasible therapeutic option显示文摘We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation(RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism.Guilherme Lopes P Martins Joao Paulo G Bernardes Marcello S Rovella Raphael G Andrade Publio Cesar C Viana Paulo Herman Giovanni Guido Cerri Marcos Roberto Menezes 2015World Journal of Gastroenterology2015,21,20:17
3Comparison between endoscopic sphincterotomy vs endoscopic sphincterotomy associated with balloon dilation for removal of bile duct stones:A systematic review and meta-analysis based on randomized controlled trials显示文摘AIM To compare gallstones removal rate and incidence of bleeding, pancreatitis, use of mechanical lithotripsy, cholangitis and perforation between isolated sphincterotomy vs sphincterotomy associated with balloon dilation of papilla in choledocholithiasis through the meta-analysis of randomized clinical trials. METHODS We conducted a systematic review according to the PRISMA guidelines. Literature search was restricted to randomized controlled trials(RCTs) on Med Line, Cochrane Library, LILACS, and EMBASE database platforms in July 2017. The manual search included references of retrieved articles. We extracted data focusing on outcomes: The primary endpoint was the stones removal rate; Secondary endpoints were rates of pancreatitis, bleeding, use of mechanical lithotripsy(ML), perforation and cholangitis. RESULTS Eleven RCTs with 1824 patients were included. EST was associated with more post-endoscopic retrograde cholangiopancreatography(ERCP) bleeding [FE RD-0.02, CI(-0.03,-0.00), I2 = 33%, P = 0.05] and more need of mechanical lithotripsy in general [RE RD-0.16, CI(-0.25,-0.06), I2 = 90%, P = 0.002] and in subgroup analysis of stones greater than 15 mm [RE RD-0.20, CI(-0.38,-0.02), I2 = 82%, P = 0.003]. Incidence of pancreatitis [FE RD-0.01, CI(-0.03, 0.01), I2 = 0, P = 0.36], cholangitis [FE RD-0.00, CI(-0.01, 0.01), I2 =0, P = 0.97] and perforation [FE RD-0.01, CI(-0.01, 0.00), I2 = 0, P = 0.23] was similar between the groups as well as similar stone removal rates in general [FE RD-0.01, CI(-0.01, 0.04), I2 = 0, P = 0.23] and pooled analysis of stones greater than 15 mm [FE RD-0.02, CI(-0.02, 0.07), I2 = 11%, P = 0.31]. CONCLUSION Through meta-analysis of randomized clinical trials we found that isolated sphincterotomy was associated with more post-ERCP bleeding and more need for mechanical lithotripsy. However, there was no statistical difference in the stone removal rate between isolated sphincterotomy and sphincterotomy associated with balloon dilation in the approach to remove gallstones.Cesar Capel de Clemente Junior Wanderley Marques Bernardo Tomazo Prince Franzini Gustavo Oliveira Luz Marcos Eduardo Lera dos Santos Jonah Maxwell Cohen Diogo Turiani Hourneaux de Moura Fábio Ramalho Tavares Marinho Martin Coronel Paulo Sakai Eduardo Guimaraes Hourneaux de Moura 2018World Journal of Gastrointestinal Endoscopy2018,10,8:8

6Explaining the influence of dopant concentration and excitation power density on the luminescence and brightness of β-NaYF4:Yb^3+,Er^3+ nanoparticles:Measurements and simulations显示文摘We assessed the influence of Yb^3+ and Er34 dopant concentration on the relative spectral distribution, quantum yield (Фuc), and decay kinetics of the upconversion luminescence (UCL) and particle brightness (BUC) for similarly sized (33 nm) oleate-capped p-NaYF4:Yb3t,Er^3+ upconversion (UC) nanoparticles (UCNPs) in toluene at broadly varied excitation power densities (F). This included an Yb^3+ series where the Yb^3+ concentration was varied between 11%—21% for a constant Er^3+ concentration of 3%, and an Er^3+ series, where the Er^3+ concentration was varied between 1%-4% for a constant Yb^3+ concentration of 14%. The results were fitted with a coupled rate equation model utilizing the UCL data and decay kinetics of the green and red Er34 emission and the Yb34 luminescence at 980 nm. An increasing Yb34 concentration favors a pronounced triphotonic population of 4F9/2 at high P by an enhanced back energy transfer (BET) from the 4G11/2 level. Simultaneously, the Yb^3+-controlled UCNPs absorption cross section overcompensates for the reduction in Фuc with increasing Yb^3+ concentration at high P, resulting in an increase in Sue. Additionally, our results show that an increase in Yb34 and a decrease in Er^3+ concentration enhance the color tuning range by P. These findings will pave the road to a deeper understanding of the energy transfer processes and their contribution to efficient UCL, as well as still debated trends in green-to-red intensity ratios of UCNPs at different P.Martin Kaiser Christian Wurth Marco Kraft Tero Soukka Ute Resch-Genger 2019Nano Research2019,12,8:3
7Bile duct hamartomas-the von Meyenburg complex显示文摘ABSTRACT: Hamartomas of the bile duct (von Meyenburg complex) are benign neoplasms of the liver, constituted histologically cystic dilatations of the bile duct, encompassed by fibrous stroma. We report a 42-year-old female patient with symptomatic cholecystitis, whose gross and ultrasonic appearance suggestive of multiple liver metastases. Magnetic resonance imaging and liver biopsy are the gold standards for diagnosis of this rare hepatobiliary condition.Valdemir José Alegre Salles Alexandre Marotta Jorge Miguel Kather Netto Manlio Basílio Speranzini Marcos Roberto Martins 2007Hepatobiliary & Pancreatic Diseases International2007,6,1:3

9Erosion problem in tool steel using cold box core-making process显示文摘This paper presents the erosion results of the AISI H13 steel impinged by resin-bonded silica sand, using a testing rig that closely simulates the real blowing conditions during industrial core-making. Steel specimens were heat treated to obtain hardness of 294, 445 and 595 HV200 (29, 45 and 55 HRC). Erosion tests were carried out at impingement angles from 20° to 90° and air drag pressures of 1.38, 2.07 and 2.76 bar (20, 30 and 40 psi). The main results are summarized as follows:(i) The harder material, the lower erosion;(ii) the maximum erosion rate is at 30°;(iii) Little difference in erosion rate at impact angle of 60° and 90° for a constant pressure tested regardless of the hardness level;(iv) As the pressure increases, so does the erosion rate, being more sensitive for low impact angles. Finally, a differential form of the general erosion equation is applied on a practical core-making case to evaluate the erosion rate of the H13 steel at 30° and 90° impingement angles.Eduardo Rodríguez Alberto Pérez Rafael David Mercado-Solis Velasco-Téllez Abraham Omar Jimenez Martin Flores Marco Aurelio Gonzalez Jesus Ibarra 2019China Foundry2019,16,3:2
10计算机视觉技术与中国兵马俑的考古学分类研究显示文摘此项研究中,采用计算机视觉技术,通过普通照相机,在普通照明条件下连续拍摄秦兵马俑雕塑的局部,然后使用计算机软件生成3D模型,恢复陶俑雕塑,特别是陶俑耳朵的三维结构,并通过3D形态测量和生物特征对比,研究兵马俑雕塑中的个性化特征以及相关的雕塑方法。因为在过去学术研究中,就秦兵马俑的雕塑方法是模制,还是个性化雕刻,一直有很大的争议。本文以此为研究案例,旨在抛砖引玉,激发对于这一新研究领域的进一步讨论。Andrew Bevan 李秀珍 Marcos Martinón-Torres Susan Green 夏寅 赵昆 赵振 马生涛 曹玮 Thilo Rehren 王文化(译) 2019考古与文物2019,,4:2

14Mechanical Properties of Sustainable,Self-healing Porous Asphalt Concrete显示文摘Long lifetime sustainable porous asphalt concrete containing steel fibers was designed. The material is self healing in such a sense that some external stimulus is needed in the form of heating by induction energy. Steel wool was added to porous asphalt concrete to enhance its electrical conductivity and induction heating was applied to increase the temperature to heal the micro-cracks and repair the bonding between aggregate and binder. The main purpose of this paper is to examine the mechanical properties of this sustainable porous asphalt concrete including indirect tensile strength,work of fracture,particle loss resistance and water sensitivity. It is found that adding steel fibers to porous asphalt concrete to increase the healing performance also can improve its overall mechanical properties.LIU Q T ERIK SCHLANGEN MARTIN V D V MARCO POOT 2010武汉理工大学学报2010,32,17:2
15Murine model to study brain,behavior and immunity during hepatic encephalopathy显示文摘AIM:To propose an alternative model of hepatic encephalopathy(HE) in mice,resembling the human features of the disease.METHODS:Mice received two consecutive intraperitoneal injections of thioacetamide(TAA) at low dosage(300 mg/kg).Liver injury was assessed by serum transaminase levels(ALT) and liver histology(hematoxylin and eosin).Neutrophil infiltration was estimated by confocal liver intravital microscopy.Coagulopathy was evaluated using prolonged prothrombin and partial thromboplastin time.Hemodynamic parameters were measured through tail cuff.Ammonia levels were quantified in serum and brain samples.Electroencephalography(EEG) and psychomotor activity score were performed to show brain function.Brain edema was evaluated using magnetic resonance imaging.RESULTS:Mice submitted to the TAA regime developed massive liver injury,as shown by elevation of serum ALT levels and a high degree of liver necrosis.An intense hepatic neutrophil accumulation occurred in response to TAA-induced liver injury.This led to mice mortality and weight loss,which was associated with severe coagulopathy.Furthermore,TAA-treated mice presented with increased serum and cerebral levels of ammonia,in parallel with alterations in EEG spectrum and discrete brain edema,as shown by magnetic resonance imaging.In agreement with this,neuropsychomotor abnormalities ensued 36 h after TAA,fulfilling several HE features observed in humans.In this context of liver injury and neurological dysfunction,we observed lung inflammation and alterations in blood pressure and heart rate that were indicative of multiple organ dysfunction syndrome.CONCLUSION:In summary,we describe a new murine model of hepatic encephalopathy comprising multiple features of the disease in humans,which may provide new insights for treatment.Lindisley Ferreira Gomides Pedro Elias Marques Bruno Engler Faleiros Rafaela Vaz Pereira Sylvia Stella Amaral Thais Reis Lage Gustavo Henrique Souza Resende Patricia Alves Maia Guidine Giselle Foureaux Fabíola Mara Ribeiro Fabiana Paiva Martins Marco Antonio Peliky Fontes Anderson José Ferreira Remo Castro Russo Mauro Martins Teixeira Márcio Flávio Moraes Antonio Lúcio Teixeira Gustavo Batista Menezes 2014World Journal of Hepatology2014,6,4:2
