| 1 | Risk of cardiovascular,cardiac and arrhythmic complications in patients with non-alcoholic fatty liver disease显示文摘Non-alcoholic fatty liver disease(NAFLD)has emerged as a public health problem of epidemic proportions worldwide.Accumulating clinical and epidemiological evidence indicates that NAFLD is not only associated with liver-related morbidity and mortality but also with an increased risk of coronary heart disease(CHD),abnormalities of cardiac function and structure(e.g.,left ventricular dysfunction and hypertrophy,and heart failure),valvular heart disease(e.g.,aortic valve sclerosis)and arrhythmias(e.g.,atrial fibrillation).Experimental evidence suggests that NAFLD itself,especially in its more severe forms,exacerbates systemic/hepatic insulin resistance,causes atherogenic dyslipidemia,and releases a variety of pro-inflammatory,pro-coagulant and pro-fibrogenic mediators that may play important roles in the pathophysiology of cardiac and arrhythmic complications.Collectively,these findings suggest that patients with NAFLD may benefit from more intensive surveillance and early treatment interventions to decrease the risk for CHD and other cardiac/arrhythmic complications.The purpose of this clinical review is to summarize the rapidly expanding body of evidence that supports a strong association between NAFLD and cardiovascular,cardiac and arrhythmic complications,to briefly examine the putative biological mechanisms underlying this association,and to discuss some of the current treatment options that may influence both NAFLD and its related cardiac and arrhythmic complications. | Stefano Ballestri Amedeo Lonardo Stefano Bonapace Christopher D Byrne Paola Loria Giovanni Targher | 2014 | World Journal of Gastroenterology2014，20，7： | 55 |
| 2 | Resection vs thermal ablation of small hepatocellular carcinoma:What's the first choice?显示文摘Nowadays,hepatocellular carcinoma(HCC) is frequently diagnosed at an early stage,opening good perspectives to radical treatment by means of liver transplantation,surgical resection,or percutaneous ablation.Liver transplantation is considered the best option,but the lack of liver donors represents a major limitation.Therefore,surgical resection,offering a 5-year-survival rate of over 50%,is considered the first-choice treatment for patients with early stage HCC,whereas percutaneous ablation is usually reserved to patients who are not candidate to surgery.However,in the recent years some trials showed that percutaneous radiofrequency ablation(RFA) can be as effective as surgical resection in terms of overall survival and recurrencefree survival rates in patients with small HCC,and a retrospective comparative study reported 1-,3-,and 5-year overall survival rates and recurrence-free survival rates significantly better in patients with central HCC measuring 2 cm or smaller treated with RFA than in those treated with surgical resection.RFA is less expensive,less invasive,with lower complication rate and shorter hospital stay than surgical resection,and on the basis of the results of these studies it should be considered the first option in the treatment of very early HCC.However,RFA is size-dependent,so at present the need to achieve an adequate safety margin around the tumor limits to about 2 cm the diameter of the nodules that can be ablated with long-term outcomes comparable to or better than surgical resection.The main goal of the next technical developments of the thermal ablation systems should be the achievement of larger ablation areas with a single needle insertion.In this regard,the recent improvements in microwave energy delivery systems seem to open interesting perspectives to percutaneous microwave ablation,which could become the ablation technique of choice in the next future. | Paola Tombesi Francesca Di Vece Sergio Sartori | 2013 | World Journal of Radiology2013，5，1： | 50 |
| 3 | Major osteoporotic fragility fractures: Risk factor updates and societal impact显示文摘Osteoporosis is a silent disease without any evidence of disease until a fracture occurs. Approximately 200 million people in the world are affected by osteoporosis and 8.9 million fractures occur each year worldwide. Fractures of the hip are a major public health burden, by means of both social cost and health condition of the elderly because these fractures are one of the main causes of morbidity, impairment, decreased quality of life and mortality in women and men. The aim of this review is to analyze the most important factors related to the enormous impact of osteoporotic fractures on population. Among the most common risk factors, low body mass index; history of fragility fracture, environmental risk, early menopause, smoking, lack of vitamin D, endocrine disorders(for example insulin-dependent diabetes mellitus), use of glucocorticoids, excessive alcohol intake, immobility and others represented the main clinical risk factors associated with augmented risk of fragility fracture. The increasing trend of osteoporosis is accompanied by an underutilization of the available preventive strategies and only a small number of patients at high fracture risk are recognized and successively referred for therapy. This report provides analytic evidences to assess the best practices in osteoporosis management and indications for the adoption of a correct healthcare strategy to significantly reduce the osteoporosis burden. Early diagnosis is the key to resize the impact of osteoporosis on healthcare system. In this context, attention must be focused on the identification of high fracture risk among osteoporotic patients. It is necessary to increase national awareness campaigns across countries in order to reduce the osteoporotic fractures incidence. | Paola Pisani Maria Daniela Renna Francesco Conversano Ernesto Casciaro Marco Di Paola Eugenio Quarta Maurizio Muratore Sergio Casciaro | 2016 | World Journal of Orthopedics2016，7，3： | 39 |
| 4 | Hepatocellular carcinoma in nonalcoholic fatty liver: Role of environmental and genetic factors显示文摘Hepatocellular carcinoma(HCC) is the fourth cause of cancer related mortality, and its incidence is rapidly increasing. Viral hepatitis, alcohol abuse, and exposure to hepatotoxins are major risk factors, but nonalcoholic fatty liver disease(NAFLD) associated with obesity, insulin resistance, and type 2 diabetes, is an increasingly recognized trigger, especially in developed countries. Older age, severity of insulin resistance and diabetes, and iron overload have been reported to predispose to HCC in this context. Remarkably, HCCs have been reported in non-cirrhotic livers in a higher proportion of cases in NAFLD patients than in other etiologies. Inherited factors have also been implicated to explain the different individual susceptibility to develop HCC, and their role seems magnified in fatty liver, where only a minority of affected subjects progresses to cancer. In particular, the common I148 M variant of the PNPLA3 gene influencing hepatic lipid metabolism influences HCC risk independently of its effect on the progression of liver fibrosis. Recently, rare loss-of-function mutations in Apolipoprotein B resulting in very low density lipoproteins hepatic retention and in Telomerase reverse transcriptase influencing cellular senescence have also been linked to HCC in NAFLD. Indeed, hepatic stellate cells senescence has been suggested to bridge tissue aging with alterations of the intestinal microbiota in the pathogenesis of obesity-related HCC. A deeper understanding of the mechanisms mediating hepatic carcinogenesis during insulin resistance, and the identification of its genetic determinants will hopefully provide new diagnostic and therapeutic tools. | Paola Dongiovanni Stefano Romeo Luca Valenti | 2014 | World Journal of Gastroenterology2014，20，36： | 38 |
| 5 | Human NK cells: surface receptors, inhibitory checkpoints, and translational applications显示文摘NK cells play important roles in innate defenses against viruses and in the control of tumor growth and metastasis.The regulation/induction of NK cell function is mediated by an array of activating or inhibitory surface receptors.In humans,major activating receptors involved in target cell killing are the natural cytotoxicity receptors(NCRs)and NKG2D.Activating receptors recognize ligands that are overexpressed or expressed de novo upon cell stress,viral infection,or tumor transformation.The HLA-class I-specific inhibitory receptors,including KIRs recognizing HLA-class I allotypic determinants and CD94/NKG2A recognizing the class-Ib HLA-E,constitute a fail-safe mechanism to avoid unwanted NK-mediated damage to healthy cells.Other receptors such as PD-1,primarily expressed by activated T lymphocytes,are important inhibitory checkpoints of immune responses that ensure T-cell tolerance.PD-1 also may be expressed by NK cells in cancer patients.Since PD-1 ligand(PD-L1)may be expressed by different tumors,PD-1/PD-L1 interactions inactivate both T and NK cells.Thus,the reliable evaluation of PD-L1 expression in tumors has become a major issue to select patients who may benefit from therapy with mAbs disrupting PD-1/PD-L1 interactions.Recently,NKG2A was revealed to be an important checkpoint controlling both NK and T-cell activation.Since most tumors express HLA-E,mAbs targeting NKG2A has been used alone or in combination with other therapeutic mAbs targeting PD-1 or tumor antigens(e.g.,EGFR),with encouraging results.The translational value of NK cells and their receptors is evidenced by the extraordinary therapeutic success of haploidentical HSCT to cure otherwise fatal high-risk leukemias. | Simona Sivori Paola Vacca Genny Del Zotto Enrico Munari Maria Cristina Mingari Lorenzo Moretta | 2019 | Cellular & Molecular Immunology2019，16，5： | 33 |
| 6 | 学前语言教育的新取向:重视儿童学业语言的发展显示文摘目前国际语言与教育的研究特别关注儿童学业语言的发展和教育。学业语言是儿童语言发展过程中所学习运用的一种特别的语言能力。学业语言是一种可以通过口头语言进行交流,但是具有书面语言特征的语言。学前阶段儿童的学业语言发展具有自身的年龄特点。幼教工作者应该认识到阅读是通向儿童学业语言成长的重要途径;应在阅读基础上或者围绕某个学习内容开展拓展性讨论;应关注说明性讲述活动,帮助学前儿童系统使用学业语言进行表达。 | 周兢 陈思 Catherine Snow Paola Uccelli | 2014 | 学前教育研究2014，，6： | 28 |
| 7 | Pediatric nonalcoholic fatty liver disease,metabolic syndrome and cardiovascular risk显示文摘Nonalcoholic fatty liver disease(NAFLD) encompasses a range of liver histology severity and outcomes in the absence of chronic alcohol use.The mildest form is simple steatosis in which triglycerides accumulate within hepatocytes.A more advanced form of NAFLD,nonalcoholic steatohepatitis,includes inflammation and liver cell injury,progressive to cryptogenic cirrhosis.NAFLD has become the most common cause of chronic liver disease in children and adolescents.The recent rise in the prevalence rates of overweight and obesity likely explains the NAFLD epidemic worldwide.NAFLD is strongly associated with abdominal obesity,type 2 diabetes,and dyslipidemia,and most patients have evidence of insulin resistance.Thus,NAFLD shares many features of the metabolic syndrome(MetS),a highly atherogenic condition,and this has stimulated interest in the possible role of NAFLD in the development of atherosclerosis.Accumulating evidence suggests thatNAFLD is associated with a significantly greater overall mortality than in the general population,as well as with increased prevalence of cardiovascular disease(CVD),independently of classical atherosclerotic risk factors.Yet,several studies including the pediatric population have reported independent associations between NAFLD and impaired flow-mediated vasodilatation and increased carotid artery intimal medial thickness-two reliable markers of subclinical atherosclerosis-after adjusting for cardiovascular risk factors and MetS.Therefore,the rising prevalence of obesity-related MetS and NAFLD in childhood may lead to a parallel increase in adverse cardiovascular outcomes.In children,the cardiovascular system remains plastic and damage-reversible if early and appropriate interventions are established effectively.Therapeutic goals for NAFLD should address nutrition,physical activity,and avoidance of smoking to prevent not only end-stage liver disease but also CVD. | Lucia Pacifico Valerio Nobili Caterina Anania Paola Verdecchia Claudio Chiesa | 2011 | World Journal of Gastroenterology2011，17，26： | 24 |
| 8 | Incidence of gallstone disease in Italy:Results from a multicenter,population-based Italian study (the MICOL project)显示文摘AIM:To evaluate gallstone incidence and risk factors in a large population-based study. METHODS: Gallstone incidence and risk factors, were evaluated by structured questionnaire and physical examination, respectively, in 9611 of 11 109 (86.5%) subjects who were gallstone-free at the cross-sectional study. RESULTS: Six centers throughout Italy enrolled 9611 subjects (5477 males, 4134 females, aged 30-79 years), 9517 of whom were included into analysis: 424 subjects (4.4%) had gallstones and 61 (0.6%) had been cholecystectomized yielding a cumulative incidence of 0.67% per year (0.66% in males, 0.81% in females). Increasing age, a high body mass index (BMI), a history of diabetes, peptic ulcer and angina, and low cholesterol and high triglyceride levels were identifi ed as risk factors in men while, in females, the only risk factors were increasing age and a high BMI.Increasing age and pain in the right hypocondrium in men and increasing age in females were identifi ed as predictors of gallstones. Pain in the epigastrium/ right hypocondrium was the only symptom related to gallstones; furthermore, some characteristics of pain (forcing to rest, not relieved by bowel movements) were significantly associated with gallstones. No correlation was found between gallstone characteristics and clinical manifestations, while increasing age in men and increasing age and BMI in females were predictors of pain. CONCLUSION:Increasing age and BMI represent true risk factors for gallstone disease (GD); pain in the right hypocondrium and/or epigastrium is confi rmed as the only symptom related to gallstones. | Davide Festi Ada Dormi Simona Capodicasa Tommaso Staniscia Adolfo F Attili Paola Loria Paolo Pazzi Giuseppe Mazzella Claudia Sama Enrico Roda Antonio Colecchia | 2008 | World Journal of Gastroenterology2008，14，34： | 23 |
| 9 | Contrast-enhanced ultrasonography in peripheral lung consolidations: What's its actual role?显示文摘AIM:To evaluate the diagnostic accuracy of contrastenhanced ultrasonography(CEUS)in the differential diagnosis between neoplastic and non-neoplastic peripheral pleuro-pulmonary lesions.METHODS:One hundred patients with pleural or peripheral pulmonary lesions underwent thoracic CEUS.An 8 microliters/mL solution of sulfur hexafluoride microbubbles stabilized by a phospholipid shell(SonoVue)was used as US contrast agent.The clips were stored and independently reviewed by two readers,who recorded the following parameters:presence/absence of arterial enhancement,time to enhancement(TE),extent of enhancement(EE),pattern of enhancement(PE),presence/absence of wash-out,time to wash-out,and extent of wash-out.After the final diagnosis(based on histopathologic findings or follow-up of at least 15 mo)was reached,sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV),positive likelihood ratio(PLR),negative likelihood ratio(NLR)of each CEUS parameter in the differential diagnosis between neoplastic and nonneoplastic lesions were calculated.Furthermore,an arbitrary score based on the ratio between the PPVs of each CEUS parameter was calculated,to evaluate if some relationship could exist between overall CEUS behaviour and neoplastic or non-neoplastic nature of the lesions. | Sergio Sartori Simona Postorivo Francesca Di Vece Fran-cesca Ermili Davide Tassinari Paola Tombesi | 2013 | World Journal of Radiology2013，5，10： | 19 |
| 10 | High circulating D-dimers are associated with ascites and hepatocellular carcinoma in liver cirrhosis显示文摘AIM: To measure plasma D-dimer levels in cirrhotic patients with and without ascites, assessing the effect of ascites resolution in D-dimer concentration. METHODS: Seventy consecutive cirrhotic patients (M = 44, F = 26, mean age 65 years, SD ± 13), observed from October 2005 to March 2006 were enrolled. Circulating D-dimer levels were measured using a latex-enhanced, immunoturbidimetric test. In patients with ascites (n = 42) the test was repeated after ascites resolution. RESULTS: Ascites was present in 42 patients (group A) and absent in 28 (group B). Group A patients had more advanced liver disease. Hepatocellular carcinoma (HCC) was diagnosed in 14 patients and was more frequent in group B. Above normal range D-dimers were found in 45/70 patients. High D-dimers were more frequent in group A than in group B (P = 0.001). High D-dimers were associated with presence of HCC (P = 0.048) only in group B. After ascites resolution, obtained in all patients, mean D-dimer values decreased in those 34 patients with high basal levels (P = 0.007), returning to normal in 17. CONCLUSION: In patients with liver cirrhosis, ascites and HCC are the main factors associated with increased fibrinolytic activity. | Aldo Spadaro Vincenza Tortorella Carmela Morace Agostino Fortiguerra Paola Composto Caterina Bonfiglio Angela Alibrandi Carmelo Luigiano Giuseppe De Caro Antonino Ajello Oscar Ferraù Maria Antonietta Freni | 2008 | World Journal of Gastroenterology2008，14，10： | 19 |
| 11 | Emerging roles for transthoracic ultrasonography in pulmonary diseases显示文摘As a result of many advantages such as the absence of radiation exposure,non-invasiveness,low cost,safety,and ready availability,transthoracic ultrasonography(TUS) represents an emerging and useful technique in the management of pleural and pulmonary diseases.In this second part of a comprehensive review that deals with the role of TUS in pleuropulmonary pathology,the normal findings,sonographic artifacts and morphology of the most important and frequent pulmonary diseases are described.In particular,the usefulness of TUS in diagnosing or raising suspicion of pneumonia,pulmonary embolism,atelectasis,diffuse parenchymal diseases,adult and newborn respiratory distress syndrome,lung cancer and lung metastases are discussed,as well as its role in guidance for diagnostic and therapeutic interventional procedures.Moreover,the preliminary data about the role of contrast enhanced ultrasonography in the study of pulmonary pleural-based lesions are also reported.Finally,the limits of TUS when compared with chest computed tomography are described,highlighting the inability of TUS to depict lesions that are not in contact with the pleura or are located under bony structures,poor visualization of the mediastinum,and the need for very experienced examiners to obtain reliable results. | Sergio Sartori Paola Tombesi | 2010 | World Journal of Radiology2010，2，6： | 18 |

| 13 | PNPLA3 I148M polymorphism and progressive liver disease显示文摘The 148 Isoleucine to Methionine protein variant(I148M)of patatin-like phospholipase domain-containing 3(PNPLA3),a protein is expressed in the liver and is involved in lipid metabolism,has recently been identified as a major determinant of liver fat content.Several studies confirmed that the I148M variant predisposes towards the full spectrum of liver damage associated with fatty liver:from simple steatosis to steatohepatitis and progressive fibrosis.Furthermore,the I148M variant represents a major determinant of progression of alcohol related steatohepatitis to cirrhosis,and to influence fibrogenesis and related clinical outcomes in chronic hepatitis C virus hepatitis,and possibly chronic hepatitis B virus hepatitis,hereditary hemochromatosis and primary sclerosing cholangitis.All in all,studies suggest that the I148M polymorphism may represent a general modifier of fibrogenesis in liver diseases.Remarkably,the effect of the I148M variant on fibrosis was independent of that on hepatic steatosis and inflammation,suggesting that it may affect both the quantity and quality of hepatic lipids and the biology of non-parenchymal liver cells besides hepatocytes,directly promoting fibrogenesis.Therefore,PNPLA3 is a key player in liver disease progression.Assessment of the I148M polymorphism will possibly inform clinical practice in the future,whereas the determination of the effect of the 148M variant will reveal mechanisms involved in hepatic fibrogenesis. | Paola Dongiovanni Benedetta Donati Roberta Fares Rosa Lombardi Rosellina Margherita Mancina Stefano Romeo Luca Valenti | 2013 | World Journal of Gastroenterology2013，19，41： | 17 |
| 14 | Enteric glial cells and their role in gastrointestinal motor abnormalities: Introducing the neuro-gliopathies显示文摘The role of enteric glial cells has somewhat changed from that of mere mechanical support elements, gluing together the various components of the enteric nervous system, to that of active participants in the complex interrelationships of the gut motor and inflammatory events. Due to their multiple functions, spanning from supporting elements in the myenteric plexuses to neurotransmitters, to neuronal homeostasis, to antigen presenting cells, this cell population has probably more intriguing abilities than previously thought. Recently, some evidence has been accumulating that shows how these cells may be involved in the pathophysiological aspects of some diseases. This review will deal with the properties of the enteric glial cells more strictly related to gastrointestinal motor function and the human pathological conditions in which these cells may play a role, suggesting the possibility of enteric neuro- gliopathies. | Gabrio Bassotti Vincenzo Villanacci Simona Fisogni Elisa Rossi Paola Baronio Carlo Clerici Christoph A Maurer Gieri Cathomas Elisabetta Antonelli | 2007 | World Journal of Gastroenterology2007，13，30： | 16 |

| 16 | Endoscopic management of esophageal stenosis in children:New and traditional treatments显示文摘Post-esophageal atresia anastomotic strictures and postcorrosive esophagitis are the most frequent types of cicatricial esophageal stricture. Congenital esophageal stenosis has been reported to be a rare but typical disease in children; other pediatric conditions are peptic, eosinophilic esophagitis and dystrophic recessive epidermolysis bullosa strictures. The conservative treatment of esophageal stenosis and strictures(ES) rather than surgery is a well-known strategy for children. Before planning esophageal dilation, the esophageal morphology should be assessed in detail for its length, aspect, number and level, and different conservative strategies should be chosen accordingly. Endoscopic dilators and techniques that involve different adjuvant treatment strategies have been reported and depend on the stricture's etiology, the availability of different tools and the operator's experience and preferences. Balloon and semirigid dilators are the most frequently used tools. No high-quality studies have reported on the differences in the efficacies and rates of complications associated with these two types of dilators. There is no consensus in the literature regarding the frequency of dilations or the diameter that should be achieved. The use of adjuvant treatments has been reported in cases of recalcitrant stenosis or strictures with evidence of dysphagic symptoms. Corticosteroids(either systemically or locally injected), the local application of mitomycin C, diathermy and laser ES sectioning have been reported. Some authors have suggested that stenting can reduce both the number of dilations and the treatment length. In many cases, this strategy is effective when either metallic or plastic stents are utilized. Treatment complications, such esophageal perforations, can be conservatively managed, considering surgery only in cases with severe pleural cavity involvement. In cases of stricture relapse,even if such relapses occur following the execution of well-conducted conservative strategies, surgical stricture resection and anastomosis or esophageal substitution are the only remaining options. | Luigi Dall rsquo Oglio Tamara Caldaro Francesca Foschia Simona Faraci Giovanni Federici di Abriola Francesca Rea Erminia Romeo Filippo Torroni Giulia Angelino Paola De Angelis | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，4： | 16 |
| 17 | Acute kidney injury and post-reperfusion syndrome in liver transplantation显示文摘In the past decades liver transplantation(LT) has become the treatment of choice for patients with end stage liver disease(ESLD). The chronic shortage of cadaveric organs for transplantation led to the utilization of a greater number of marginal donors such as older donors or donors after circulatory death(DCD). The improved survival of transplanted patients has increased the frequency of long-term complications, in particular chronic kidney disease(CKD). Acute kidney injury(AKI) post-LT has been recently recognized as an important risk factor for the occurrence of denovo CKD in the long-term outcome. The onset of AKI post-LT is multifactorial, with pre-LT risk factors involved, including higher Model for End-stage Liver Disease score, more sever ESLD and pre-existing renal dysfunction, either with intra-operative conditions, in particular ischaemia reperfusion injury responsible for post-reperfusion syndrome(PRS) that can influence recipient's morbidity and mortality. Post-reperfusion syndrome-induced AKI is an important complication post-LT that characterizes kidney involvement caused by PRS with mechanisms not clearly understood and implication on graft and patient survival. Since preLT risk factors may influence intra-operative events responsible for PRS-induced AKI, we aim to consider all the relevant aspects involved in PRS-induced AKI in the setting of LT and to identify all studies that better clarified the specific mechanisms linking PRS and AKI. A Pub Med search was conducted using the terms liver transplantation AND acute kidney injury; liver transplantation AND post-reperfusion syndrome; acute kidney injury AND post-reperfusion syndrome; acute kidney injury AND DCD AND liver transplantation. Five hundred seventy four articles were retrieved on Pub Med search. Results were limited to title/abstract of English-language articles published between 2000 and 2015. Twenty-three studies were identified that specifically evaluated incidence, risk factors and outcome for patients developing PRS-induced AKI in liver transplantation. In order to identify intra-operative risk factors/mechanisms specifically involved in PRSinduced AKI, avoiding confounding factors, we have limited our study to 'acute kidney injury AND DCD AND liver transplantation'. Accordingly, three out of five studies were selected for our purpose. | Ilaria Umbro Francesca Tinti Irene Scalera Felicity Evison Bridget Gunson Adnan Sharif James Ferguson Paolo Muiesan Anna Paola Mitterhofer | 2016 | World Journal of Gastroenterology2016，22，42： | 16 |
| 18 | Pancreatic 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 | 2017 | World Journal of Gastroenterology2017，23，2： | 16 |
| 19 | Computed tomography findings of pneumatosis and portomesenteric venous gas in acute bowel ischemia显示文摘AIM:To use more representative sample size to evaluate whether computed tomography(CT)scan evidence of the concomitant presence of pneumatosis and portomesenteric venous gas is a predictor of transmural bowel necrosis.METHODS:Data from 208 patients who were referred for a diagnosis of bowel ischemia were retrospectively reviewed.Only patients who underwent a surgical intervention following a diagnosis of bowel ischemia who also had a post-operative histological confirmation of such a diagnosis were included.Patients were split into two groups according to the presence of histological evidence of transmural bowel ischemia(case group)or partial bowel ischemia(control group).CT images were reviewed for findings of ischemia,including mural thickening,pneumatosis,bowel distension,portomesenteric venous gas and arterial or venous thrombi.RESULTS:A total of 248 subjects who underwent surgery for bowel ischemia were identified.Among the208 subjects enrolled in our study,transmural bowel necrosis was identified in 121 subjects(case group),and partial bowel necrosis was identified in 87 subjects(control group).Based on CT findings,including mural thickening,bowel distension,pneumatosis,pneumatosis plus portomesenteric venous gas and presence of thrombi or emboli,there were no significant differences between the case and control groups.The concomitant presence of pneumatosis and porto-mesenteric venous gas showed an odds ratio of 1.95(95%CI:0.491-7.775,P=0.342)for the presence of transmural necrosis.The presence of pneumatosis plus porto-mesenteric venous gas exhibited good specificity(83%)but low sensitivity(17%)in the identification of transmural bowel infarction.Accordingly,the positive and negative predictive values were 60% and 17%,respectively.CONCLUSION:Although pneumatosis plus porto-mesenteric venous gas is associated with bowel ischemia,we have demonstrated that their co-occurrence cannot be used as diagnostic signs of transmural necrosis. | Marco Milone Matteo Nicola Dario Di Minno Mario Musella Paola Maietta Vittorio Iaccarino Giovanni Barone Francesco Milone | 2013 | World Journal of Gastroenterology2013，19，39： | 15 |
| 20 | Diagnostic and therapeutic implications of the association between ferritin level and severity of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD),defined by excessive liver fat deposition related to the metabolic syndrome,is a leading cause of progressive liver disease,for which accurate non-invasive staging systems and effective treatments are still lacking.Evidence has shown that increased ferritin levels are associated with the metabolic insulin resistance syndrome,and higher hepatic iron and fat content.Hyperferritinemia and iron stores have been associated with the severity of liver damage in NAFLD,and iron depletion reduced insulin resistance and liver enzymes.Recently,Kowdley et al demonstrated in a multicenter study in 628 adult patients with NAFLD from the NAFLD-clinical research network database with central re-evaluation of liver histology and iron staining that the increased serum ferritin level is an independent predictor of liver damage in patients with NAFLD,and is useful to identify NAFLD patients at risk of non-alcoholic steatohepatitis and advanced fibrosis.These data indicate that incorporation of serum ferritin level may improve the performance of noninvasive scoring of liver damage in patients with NAFLD,and that iron depletion still represents an attractive therapeutic target to prevent the progression of liver damage in these patients. | Luca Valenti Paola Dongiovanni Silvia Fargion | 2012 | World Journal of Gastroenterology2012，18，29： | 15 |
