1Pancreatic neuroendocrine neoplasms: Magnetic resonance imaging features according to grade and stage显示文摘AIM To describe magnetic resonance(MR) imaging features of pancreatic neuroendocrine neoplasms(Pan NENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and todetermine the accuracy of MR imaging features in predicting their biological behavior.METHODS This study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 Pan NEN patients(29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis.RESULTS Ill defined margins were more common in G2-3 and stage Ⅲ-Ⅳ PanN ENs than in G1 and low-stage tumors(P < 0.001); this feature had high specificity in the identification of G2-3 and stage Ⅲ-Ⅳ tumors(90.3% and 96%, 95%CI: 73.1-97.5 and 77.7-99.8). The mean apparent diffusion coefficient value was significantly lower in G2-3 and stage Ⅲ-Ⅳ lesions compared to well differentiated and low-stage tumors(1.09 × 10-3 mm2/s vs 1.45 × 10-3 mm2/s and 1.10 × 10-3 mm2/s vs 1.53 × 10-3 mm2/s, P = 0.003 and 0.001). Receiving operator characteristic analysis determined optimal cutoffs of 1.21 and 1.28 × 10-3 mm2/s for the identification of G2-3 and stage Ⅲ-Ⅳ tumors, with sensitivity and specificity values of 70.8/80.7% and 64.5/64%(95%CI: 48.7-86.6/60-92.7 and 45.4-80.2/42.6-81.3).CONCLUSION MR features of PanN ENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.Riccardo De Robertis Sara Cingarlini Paolo Tinazzi Martini Silvia Ortolani Giovanni Butturini Luca Landoni Paolo Regi Roberto Girelli Paola Capelli Stefano Gobbo Giampaolo Tortora Aldo Scarpa Paolo Pederzoli Mirko D'Onofrio 2017World Journal of Gastroenterology2017,23,2:16
2Helicobacter pylori-negative Russell body gastritis:Case report显示文摘Russell body gastritis is an unusual form of chronic gastritis characterized by the permeation of lamina propria by numerous plasma cells with eosinophilic cytoplasmic inclusions.Very few cases have been reported in the literature;the majority of which have shown Helicobacter Pylori(H.pylori)infection,thus suggesting a correlation between plasma cell presence and antigenic stimulation by H.pylori.We present a case of Russell body gastritis in a 78-year-old woman who was undergoing esophagogastroduodenoscopy for epigastric pain.Gastric biopsy of the gastroesophageal junction showed the presence of cells with periodic acid-Schiff-positive hyaline pink bodies.Giemsa staining for H.pylori infection was nega-tive,as well as immunohistochemical detection.The cells with eosinophilic inclusions stained positive for CD138,CD79a,andκand lambda light chains,which confirmed plasma cell origin.In particular,κand lambda light chains showed a polyclonal origin and the patient was negative for immunological dyscrasia.The histological observations were confirmed by ultrastructural examination.The cases reported in the literature associated with H.pylori infection have shown regression of plasma cells after eradication of H.pylori.Nothing is known about the progression of H.pylori-negative cases.The unusual morphological appearance of this type of chronic gastritis should not be misinterpreted during routine examination,and it should be distinguished from other common forms of chronic gastritis.It is mandatory to exclude neoplastic diseases such as gastric carcinoma, lymphoma and plasmocytoma by immunohistochemistry and electron microscopy,which can help with differential diagnosis.The long-term effects of plasma cells hyperactivation are still unknown,because cases of gastric tumor that originated in patients affected by Russell body gastritis have not been described in the literature.We are of the opinion that these patients should be scheduled for endoscopic surveillance.Alessandro Del Gobbo Luca Elli Paola Braidotti Franca Di Nuovo Silvano Bosari Solange Romagnoli 2011World Journal of Gastroenterology2011,17,9:3
3Seismic Performance Assessment of a Conventional Multi-storey Building显示文摘Recent earthquakes have revealed that conventional seismic design philosophy allows for large levels of nonstructural damage. Nonstructural earthquake damage results in extensive repair costs and lengthy functional disruptions, as nonstructural systems comprise the majority of building investment and are essential to building operations. A better understanding of the expected overall seismic performance of code-compliant buildings is needed. This study investigates the seismic performance of a conventional building. A 16-storey steel office building was designed using a modern seismic structural code(Eurocode 8). This study is the first to assess in detail the substantial earthquake repair costs expected in a modern Eurocode concentric braced frame structure, considering nonstructural systems with the FEMA P-58 procedure. The breakdown of total repair costs by engineering demand parameter and by fragility group is novel. The seismic performance assessment indicated that substantial earthquake repair costs are expected. Limitations of the Eurocode nonstructural damage methodology were revealed in a novel manner using FEMA P-58, as the prescribed drift limits did not minimize nonstructural repair costs. These findings demonstrate the need for design procedures that improve nonstructural seismic performance. The study results provide a benchmark on which to evaluate retrofit alternatives for existing buildings and design options for new structures.Giuseppe Marcantonio Del Gobbo Martin S.Williams Anthony Blakeborough 2017International Journal of Disaster Risk Science2017,8,3:2

5Imaging response predictors following drug eluting beads chemoembolization in the neoadjuvant liver transplant treatment of hepatocellular carcinoma显示文摘BACKGROUND Drug-eluting bead transarterial chemoembolization(DEB-TACE)is an endovascular treatment to release chemotherapeutic agents within a target lesion,minimizing systemic exposure and adverse effects to chemotherapeutics.Therefore,identifying which patient characteristics may predict imaging response to DEB-TACE can improve treatment results while selecting the best candidates.Predictors of the response after DEB-TACE still have not been fully elucidated.This is the first prospective study performed with standardized DEBTACE technique that aim to identify predictors of radiological response,assessing patients clinical and laboratory characteristics,diagnostic imaging and intraprocedure data of the hepatocellular carcinoma treated in the neoadjuvant context for liver transplantation.AIM To identify pre-and intraoperative clinical and imaging predictors of the radiological response of drug-eluting bead transarterial chemoembolization(DEB-TACE)for the neoadjuvant treatment of hepatocellular carcinoma(HCC).METHODS This is prospective,cohort study,performed in a single transplant center,from 2011 to 2014.Consecutive patients with HCC considered for liver transplant who underwent DEB-TACE in the first session for downstaging or bridging purposes were recruited.Pre and post-chemoembolization imaging studies were performed by computed tomography or magnetic resonance.The radiological response of each individual HCC was evaluated by objective response using mRECIST and the percentage of necrosis.RESULTS Two hundred patients with 380 HCCs were examined.Analysis of the objective response(nodule-based analysis)demonstrated that HCC with pseudocapsules had a 2.01 times greater chance of being responders than those without pseudocapsules(P=0.01),and the addition of every 1mg of chemoembolic agent increased the chance of therapeutic response in 4%(P<0.001).Analysis of the percentage of necrosis through multiple linear regression revealed that the addition of each 1mg of the chemoembolic agent caused an average increase of 0.65%(P<0.001)in necrosis in the treated lesion,whereas the hepatocellular carcinoma with pseudocapsules presented 18.27%(P<0.001)increased necrosis compared to those without pseudocapsules.CONCLUSION The presence of a pseudocapsule and the addition of the amount of chemoembolic agent increases the chance of an objective response in hepatocellular carcinoma and increases the percentage of tumor necrosis following drug-eluting bead chemoembolization in the neoadjuvant treatment,prior to liver transplantation.Francisco Leonardo Galastri Felipe Nasser Breno Boueri Affonso Leonardo Guedes Moreira Valle Bruno Calazans Odísio Joaquim Mauricio Motta-Leal Filho Paolo Rogério Salvalaggio Rodrigo Gobbo Garcia Márcio Dias de Almeida Ronaldo Hueb Baroni Nelson Wolosker 2020World Journal of Hepatology2020,12,1:2
6神经生长因子增强小胶质细胞的神经保护作用显示文摘小胶质细胞是脑组织内的防御细胞,但在病理和生理条件下,调控小胶质细胞活化的因子并不十分清楚。本研究发现,神经生长因子(NGF)可以增强小胶质细胞的神经保护和抗炎功能。在体内和体外研究中都发现,小胶质细胞表达NGF受体。原代培养小胶质细胞,给予NGF处理,转录本分析结果显示,NGF对小胶质细胞的运动、吞噬和降解吞噬物的能力均产生影响。对功能的研究显示,NGF可增加小胶质细胞的膜运动能力和胞饮作用;在体研究显示,NGF可激活小胶质细胞释放向外整流电流,调节周围谷氨酸能神经元的神经传递。既往研究提示,小胶质细胞有清除脑内Aβ肽的功能,本研究观察了NGF对小胶质细胞吞噬能力的影响。结果显示,NGF可促进小胶质细胞通过Trk A途径清除Aβ,并加速其降解。此外,NGF还可减轻由Aβ导致的炎症激活。特异性激活小胶质细胞还可以减轻由Aβ导致的神经元树突损伤和长时程增强抑制。在对离体脑片的研究中,我们也发现NGF可以促进小胶质细胞吞噬Aβ。综上所述,本研究证实NGF可以促进小胶质细胞活化,活化的小胶质细胞通过抗炎作用减轻Aβ聚集,发挥神经保护作用。唐颖馨 Rizzi C Tiberi A Giustizieri M Marrone MC Gobbo F Carucci NM Meli G Arisi I D'Onofrio M Marinelli S Capsoni S Cattaneo A 2018神经损伤与功能重建2018,13,2:2
