| 1 | 亚太地区炎症性肠病处理共识意见(一)显示文摘虽然目前亚太地区尚无炎症性肠病(IBD)的大规模流行病学资料,但一系列研究显示其发病率和患病率呈上升趋势,与西方国家相比仍呈滞后现象,溃疡性结肠炎(UC)的发病率仍较克罗恩病(CD)高。除地域差异外,在一些多民族国家中,IBD尚可见种族差异。亚太地区IBD的遗传背景有异于西方国家,如据报道该地区CD患者未检出NOD2/CARD15变异。一般而言,该地区IBD患者的临床过程似不如西方国家严重。亚太地区IBD的诊断存在一些特殊问题。如缺乏IBD诊断金标准,存在多种小肠结肠炎,与IBD临床表现相似,使鉴别诊断特别困难。迄今为止,亚太地区IBD的诊断标准多采用西方国家的诊断标准。诊断必须逐步排除非IBD的小肠结肠炎,确诊应有典型的组织学表现,某些患者需借助随访和诊断性治疗才能确诊。进一步研究IBD发病机制将有助于开发更好的诊断标记物。亚太地区IBD的治疗亦存在特殊问题。由于诊断困难,IBD患者常未能及时接受适当的药物治疗,但该地区仍广泛采用药物治疗方案。结合西方指南和本地经验可制定类似的处理原则,以利诱导缓解和维持缓解。提倡逐级使用基于病变范围、活动性和严重度的阶梯式治疗方案,对不同病例采用综合性、个体化的方法。随着对IBD发病机制和亚太地区IBD独特性的深入理解,合理、实用的药物治疗指南和应用生物制剂治疗将改善该地区IBD的治疗前景。 | 欧阳钦 Rakesh Tandon KL Goh 潘国宗 KM Fock Claudio Fiocchi SK Lam 萧树东 张虎 梁红亮 王玉芳 | 2006 | 胃肠病学2006,11,4: | 123 |
| 2 | Etiopathogenesis of inflammatory bowel diseases显示文摘理论解释煽动性的肠疾病(IBD ) 的发病机理自从 Crohn 的疾病(CD ) 和 ulcerative (UC ) 被建议了作为疾病的二种主要形式被认出。尽管在 CD 和 UC 的织物损坏的准确原因和机制还得完全被理解,足够的进步发生了作为有效接受下列假设:IBD 是在环境因素,微生物引起的因素,和肠的免疫系统之中作为一个复杂相互作用的结果发生在遗传上易受影响的个人的不恰当的有免疫力的回答。在环境因素的一张几乎无穷的表之中,吸烟为 UC 为 CD 和一个保护的因素作为一个风险因素被识别了。在微生物引起的因素之中,没有有说服力的证据显示古典传染代理人引起 IBD,当作为具有中央重要性对正常伤寒植物群装证据点到反常有免疫力的回答时。内脏发炎被天生以及适应的免疫系统的房间调停,与非有免疫力的房间的另外的贡献,例如上皮,间充质并且 endothelial,和血小板。 | Silvio Danese Claudio Fiocchi | 2006 | World Journal of Gastroenterology2006,12,30: | 61 |
| 3 | Acute pancreatitis at the beginning of the 21st century: The state of the art显示文摘Acute pancreatitis is an acute inflammatory disease of the pancreas which can lead to a systemic inflammatory response syndrome with significant morbidity and mortality in 20% of patients. Gallstones and alcohol consumption are the most frequent causes of pancreatitis in adults. The treatment of mild acute pancreatitis is conservative and supportive; however severe episodes characterized by necrosis of the pancreatic tissue may require surgical intervention. Advanced understanding of the pathology, and increased interest in assessment of disease severity are the cornerstones of future management strategies of this complex and heterogeneous disease in the 21st century. | Alfredo F Tonsi Matilde Bacchion Stefano Crippa Giuseppe Malleo Claudio Bassi | 2009 | World Journal of Gastroenterology2009,15,24: | 54 |

| 5 | Aggressive behaviour of solid-pseudopapillary tumor of the pancreas in adults:A case report and review of the literature显示文摘Solid-pseudopapillary tumor (SPT) is a rare neoplasm of the pancreas that usually occurs in young females. It is generally considered a low-grade malignant tumor that can remain asymptomatic for several years. The occurrence of infiltrating varieties of SPT is around 10%-15%. Between 1986 and 2006, 282 cystic tumors of the pancreas were observed. Among them a SPT was diagnosed in 8 patients (2.8%) with only one infiltrating variety. This was diagnosed in a 49-year-old female 13 years after the sonographic evidence of a small pancreatic cystic lesion interpreted as a pseudocyst. The tumor invaded a long segment of the portal- mesenteric vein confluence, and was removed with a total pancreatectomy, resection of the portal vein and reconstruction with the internal jugular vein. Histological examination confirmed the R-0 resection of the primary SPT, although a vascular invasion was demonstrated. The postoperative course was uneventful, but 32 mo after surgery the patient experienced diffuse liver metastases. Chemotherapy with different drugs was started. The patient is alive and symptom-free, with stable disease, 75 mo after surgery. Twenty-five patients with invasion of the portal vein and/or of mesenteric vessels were retrieved from the literature, 16 recent patients with tumor relapse after potentially curative resection were also retrieved. The best treatment remains a radical resection whenever possible, even in locally advanced or metastatic disease. The role of chemotherapy, and/or radiotherapy, is still to be defined. | Cosimo Sperti Mattia Berselli Claudio Pasquali Davide Pastorelli Sergio Pedrazzoli | 2008 | World Journal of Gastroenterology2008,14,6: | 44 |
| 6 | Assessing the quality of studies in meta-analyses: Advantages and limitations of the Newcastle Ottawa Scale显示文摘One of the most important points in the meta-analyses is certainly represented by the assessment of the quality of the studies included in such research. The meta-analyses are considered the highest level of evidence in science. Also for this reason, the quality of the studies included should be accurately evaluated by standardized tools. The overall results of the metaanalysis depend indeed also on a rigorous evaluation of the studies quality. Among all the possible tools for this complex evaluation, the Newcastle Ottawa Scale(NOS) is one of the most used worldwide, above all for observational studies. In this review, we will discuss the strengths and limitation of the NOS, also on the basis of the branch of science in which it has been applied. | Claudio Luchini Brendon Stubbs Marco Solmi Nicola Veronese | 2017 | World Journal of Meta-Analysis2017,5,4: | 35 |
| 7 | Intestinal inflammation and colorectal cancer:A doubleedged sword?显示文摘Chronic inflammation is thought to be the leading cause of many human cancers including colorectal cancer(CRC).Accordingly,epidemiologic and clinical studies indicate that patients affected by ulcerative colitis and Crohn's disease,the two major forms of inflammatory bowel disease,have an increased risk of developing CRC.In recent years,the role of immune cells and their products have been shown to be pivotal in initiation and progression of colitis-associated CRC.On the other hand,activation of the immune system has been shown to cause dysplastic cell elimination and cancer suppression in other settings.Clinical and experimental data herein reviewed,while confirming chronic inflammation as a risk factor for colon carcinogenesis,do not completely rule out the possibility that under certain conditions the chronic activation of the mucosal immune system might protect from colonic dysplasia. | Angelamaria Rizzo Francesco Pallone Giovanni Monteleone Massimo Claudio Fantini | 2011 | World Journal of Gastroenterology2011,17,26: | 25 |
| 8 | 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 |
| 9 | Diet and microbiota in inflammatory bowel disease: The gut in disharmony显示文摘Bacterial colonization of the gut shapes both the local and the systemic immune response and is implicated in the modulation of immunity in both healthy and disease states. Recently, quantitative and qualitative changes in the composition of the gut microbiota have been detected in Crohn's disease and ulcerative colitis, reinforcing the hypothesis of dysbiosis as a relevant mechanism underlying inflammatory bowel disease(IBD) pathogenesis. Humans and microbes have coexisted and co-evolved for a long time in a mutually beneficial symbiotic association essential for maintaining homeostasis. However, the microbiome is dynamic, changing with age and in response to environmental modifications. Among such environmental factors, food and alimentary habits, progressively altered in modern societies, appear to be critical modulators of the microbiota, contributing to or co-participating in dysbiosis. In addition, food constituents such as micronutrients are important regulators of mucosal immunity, with direct or indirect effects on the gut microbiota. Moreover, food constituents have recently been shown to modulate epigenetic mechanisms, which can result in increased risk for the development and progression of IBD. Therefore, it is likely that a better understanding of the role of different food components in intestinal homeostasis and the resident microbiota will be essential for unravelling the complex molecular basis of the epigenetic, genetic and environment interactions underlying IBD pathogenesis as well as for offering dietary interventions with minimal side effects. | Davy CM Rapozo Claudio Bernardazzi Heitor Siffert Pereira de Souza | 2017 | World Journal of Gastroenterology2017,23,12: | 24 |
| 10 | Correlation between expression of cyclooxygenase-2 and the presence of inflammatory cells in human primary hepatocellular carcinoma: Possible role in tumor promotion and angiogenesis显示文摘AIM: To investigate the association of cyclooxygenase-2(COX-2) expression with angiogenesis and the number and type of inflammatory cells (macrophages/Kupffer cells;mast cells) within primary hepatocellular carcinoma (HCC)tissues and adjacent non-tumorous (MT) tissues.METHODS: Immunohistochemistry for COX-2, CD34,CD68 and mast cell tryptase (MCT) was performed on 14 well-characterized series of liver-cirrhosis-associated HCC patients. COX-2 expression and the number of inflammatory cells in tumor lesions and surrounding liver tissues of each specimen were compared. Moreover,COX-2, CD34 staining and the number of inflammatory cells in areas with different histological degrees within each tumor sample were comparatively analyzed.RESULTS: The percentage of COX-2 positive cells was significantly higher in NT tissues than in tumors. COX-2 expression was higher in well-differentiated HCC than in poorly-differentiated tissues. Few mast cells were observed within the tumor mass, whereas a higher number was observed in the surrounding tissue, especially in peri-portal spaces of NT tissues. Abundant macrophages/Kupffer cells were observed in NT tissues, whereas the number of cells was significantly lower in the tumor mass.However, a higher cell number was observed in the well-differentiated tumor and progressively decreased in relation to the differentiation grade. Within the tumor, a positive correlation was found between COX-2 expression and the number of macrophages/Kupffer cells and mast cells. Moreover, there was a positive correlation between CD34 and COX-2 expression in tumor tissues. Comparison between well- and poorly-differentiated HCC showed that the number of CD34-positive cells decreased with dedifferentiation. However, COX-2 was the only independent variable showing a positive correlation with CD34 in a multivariate analysis.CONCLUSION: The presence of inflammatory cells and COX-2 expression in liver tumor suggests a possible relationship with tumor angiogenesis. COX-2 expressing cells and the number of macrophages/Kupffer cells and mast cells decrease with progression of the disease. | Melchiorre Cervello Daniela Foderà Ada Maria Florena Maurizio Soresi Claudio Tripodo Natale D'Alessandro Giuseppe Montalto | 2005 | World Journal of Gastroenterology2005,11,30: | 21 |
| 11 | Circulating adhesion molecules in patients with virus-related chronic diseases of the liver显示文摘AIM: In the inflammatory state, intercellular adhesion molecule-1 (ICAM-1) and vascular cellular adhesion molecule-1 (VCAM-1) play a key role in promoting migration of immunological cells from the circulation to target site.Aim of our study was to investigate soluble forms of these molecules in patients with virus-related chronic liver diseases, to assess their behavior in different pathologies and correlation with severity of liver damage.METHODS: Circulating ICAM-1 and VCAM-1 were assayed by EIA commercial kits (R&D System Co.,Abington, UK) in 23 patients with chronic active hepatitis (CH), 50 subjects affected by liver cirrhosis (LC) and 15 healthy controls comparable for sex and age. In patients, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also detected by autoanalyzer.RESULTS: LC patients had significantly higher ICAM-1 values than CH patients (38.56±7.4 ng/mL vs 20.89±6.42 ng/mL; P<0.001) and these ones had significantly higher values than controls (12.92±1.08 ng/mL; P<0.001). In CH group, ICAM-1 levels were significantly related to inflammatory activity (P= 0.041) and ALT values (r= 0.77;P<0.05). VCAM-1 values were significantly increased only in LC patients (P<0.001) and related to severity of liver impairment.CONCLUSION: These findings suggest that the determination of serum ICAM-1 can be considered as an additional useful marker of hepatocellular necrosis and inflammatory activity in chronic hepatitis, while serum VCAM-1 is an indicator of liver fibrogenesis and severity of disease in cirrhosis. | Cosimo Marcello Bruno Claudio Sciacca Danila Cilio Gaetano Bertino Anna Elisa Marchese Gaetana Politi Lucia Chinnici | 2005 | World Journal of Gastroenterology2005,11,29: | 19 |
| 12 | Mediterranean diet and nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is emerging as the most common chronic liver disease, and is characterized by a wide spectrum of fat-liver disorders that can result in severe liver disease and cirrhosis. Inflammation and oxidative stress are the major risk factors involved in the pathogenesis of NAFLD. Currently, there is no consensus concerning the pharmacological treatment of NAFLD. However, lifestyle interventions based on exercise and a balanced diet for quality and quantity, are considered the cornerstone of NAFLD management. Mediterranean diet(MD), rich in polyunsaturated fats, polyphenols, vitamins and carotenoids, with their anti-inflammatory and antioxidant effects, has been suggested to be effective in preventing cardiovascular risk factors. In adults, MD has also been demonstrated to be efficacious in reducing the risk of metabolic syndrome. However, few studies are available on the effects of the MD in both adult and pediatric subjects with NAFLD. Thus, the aims of the present narrative review are to analyze the current clinical evidence on the impact of MD in patients with NAFLD, and to summarize the main mechanisms of action of MD components on this condition. | Caterina Anania Francesco Massimo Perla Francesca Olivero Lucia Pacifico Claudio Chiesa | 2018 | World Journal of Gastroenterology2018,24,19: | 19 |
| 13 | 儿童急性呼吸窘迫综合征的治疗进展(英文)显示文摘急性呼吸窘迫综合征(ARDS)是一种具有复杂病理和发病机制的异质性综合征,目前仍没有一个明确和有效的治疗对策。根据低氧血症程度,ARDS分成三类:轻度(200mmHg〈氧合指数≤300mmHg)、中度(100mmHg〈氧合指数≤200mmHg)、严重(氧合指数≤100mmHg)。治疗ARDS的基础是正确的重症监护治疗。早期管理可以改善预后,避免副作用和并发症,并提高存活率。治疗诱因(如败血症、肺炎),最大限度地减少多器官功能衰竭(MOF)、功能障碍和呼吸机相关性肺损伤(VILI)的风险在治疗过程中是至关重要的。 | Giuseppe A.

| 14 | Significance of hepatitis virus infection in the oncogenicinitiation of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is one of the most common causes of cancer-related death worldwide. Chronic infection of hepatitis B virus(HBV) and/or hepatitis C virus(HCV) is a major risk factor in the development of the HCC, independently from excessive alcohol abuse and metabolic disease. Since the biology of HBV and HCV is different, their oncogenic effect may go through different mechanisms, direct and/or indirect. Viral hepatitis infection is associated with cellular inflammation, oxidative stress, DNA damage, that may lead to subsequent hepatic injuries such as chronic hepatitis, fibrosis, cirrhosis, and finally HCC. Direct oncogenic properties of these viruses are related with their genotypic characteristics and the ability of viral proteins to interact with host proteins, thus altering the molecular pathways balance of the cells. In addition, the integration of HBV DNA, especially the gene S and X, in a particular site of the host genome can disrupt chromosomal stability and may activate various oncogenic mechanisms, including those in hematopoietic cells. Recently, several studies also had demonstrated that viral hepatitis could trigger the population of hepatic cancer stem cells. This review summarize available pre-clinical and clinical data in literature regarding oncogenic properties of HBV and HCV in the early initiation of HCC. | Caecilia HC Sukowati Korri E El-Khobar Susan I Ie Beatrice Anfuso David H Muljono Claudio Tiribelli | 2016 | World Journal of Gastroenterology2016,22,4: | 18 |
| 15 | Helicobacter pylori infection and extragastric disorders in children: A critical update显示文摘Helicobacter pylori(H. pylori) is a highly prevalent, serious and chronic infection that has been associated causally with a diverse spectrum of extragastric disorders including iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, growth retardation, and diabetes mellitus. The inverse relation of H. pylori prevalence and the increase in allergies, as reported from epidemiological studies, has stimulated research for elucidating potential underlying pathophysiological mechanisms. Although H. pylori is most frequently acquired during childhood in both developed and developing countries, clinicians are less familiar with the pediatric literature in the field. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae. A further clinical challenge is whether the progressive decrease of H. pylori in thelast decades, abetted by modern clinical practices, may have other health consequences. | Lucia Pacifico John F Osborn Valeria Tromba Sara Romaggioli Stefano Bascetta Claudio Chiesa | 2014 | World Journal of Gastroenterology2014,20,6: | 18 |
| 16 | Exocrine pancreatic insufficiency in adults:A shared position statement of the Italian association for the study of the pancreas显示文摘This is a medical position statement developed by the Exocrine Pancreatic Insufficiency collaborative group which is a part of the Italian Association for the Study of the Pancreas(AISP).We covered the main diseases associated with exocrine pancreatic insufficiency(EPI)which are of common interest to internists/gastroenterologists,oncologists and surgeons,fully aware that EPI may also occur together with many other diseases,but less frequently.A preliminary manuscript based on an extended literature search(Medline/PubMed,Cochrane Library and Google Scholar)of published reports was prepared,and key recommendations were proposed.The evidence was discussed at a dedicated meeting in Bologna during the National Meeting of the Association in October 2012.Each of the proposed recommendations and algorithms was discussed and an initial consensus was reached.The final draft of the manuscript was then sent to the AISP Council for approval and/or modification.All concerned parties approved the final version of the manuscript in June 2013. | Raffaele Pezzilli Angelo Andriulli Claudio Bassi Gianpaolo Balzano Maurizio Cantore Gianfranco Delle Fave Massimo Falconi Luca Frulloni the Exocrine Pancreatic Insufficiency collaborative(EPIc) Group | 2013 | World Journal of Gastroenterology2013,19,44: | 16 |
| 17 | Comparison of magnetic resonance spectroscopy, proton density fat fraction and histological analysis in the quantification of liver steatosis in children and adolescents显示文摘AIM To establish a threshold value for liver fat content between healthy children and those with nonalcoholic fatty liver disease(NAFLD) by using magnetic resonance imaging(MRI), with liver biopsy serving as a reference standard. METHODS The study was approved by the local ethics committee, and written informed consent was obtained from all participants and their legal guardians before the study began. Twenty-seven children with NAFLD underwent liver biopsy to assess the presence of nonalcoholic steatohepatitis. The assessment of liver fat fraction was performed using MRI, with a high field magnet and 2D gradient-echo and multiple-echo T1-weighted sequence with low flip angle and single-voxel pointresolved 1H MR-Spectroscopy(1H-MRS), corrected for T1 and T2* decays. Receiver operating characteristic curve analysis was used to determine the best cutoff value. Lin coefficient test was used to evaluate thecorrelation between histology, MRS and MRI-PDFF. A Mann-Whitney U-test and multivariate analysis were performed to analyze the continuous variables. RESULTS According to MRS, the threshold value between healthy children and those with NAFLD is 6%; using MRI-PDFF, a cut-off value of 3.5% is suggested. The Lin analysis revealed a good fit between the histology and MRS as well as MRI-PDFF.CONCLUSION MRS is an accurate and precise method for detecting NAFLD in children. | Michele Di Martino Lucia Pacifico Mario Bezzi Rossella Di Miscio Beatrice Sacconi Claudio Chiesa Carlo Catalano | 2016 | World Journal of Gastroenterology2016,22,39: | 16 |
| 18 | Hepatic cancer stem cells and drug resistance: Relevance in targeted therapies for hepatocellular carcinoma显示文摘Hepatocellular carcinoma (HCC) is one of most common malignancies in the world. Systemic treatments for HCC, particularly for advanced stages, are limited by the drug resistance phenomenon which ultimately leads to therapy failure. Recent studies have indicated an association between drug resistance and the existence of the cancer stem cells (CSCs) as tumor initiating cells. The CSCs are resistant to conventional chemotherapies and might be related to the mechanisms of the ATP Binding Cassette (ABC) transporters and alterations in the CSCs signaling pathways. Therefore, to contribute to the development of new HCC treatments, further information on the characterization of CSCs, the modulation of the ABC transporters expression and function and the signaling pathway involved in the self renewal, initiation and maintenance of the cancer are required. The combination of transporters modulators/inhibitors with molecular targeted therapies may be a potent strategy to block the tumoral progression. This review summarizes the association of CSCs, drug resistance, ABC transporters activities and changes in signaling pathways as a guide for future molecular therapy for HCC. | Caecilia HC Sukowati Natalia Rosso Lory S Crocè Claudio Tiribelli | 2010 | World Journal of Hepatology2010,2,3: | 16 |
| 19 | Pneumatosis cystoides intestinalis显示文摘Pneumatosis cystoides intestinalis(PCI) is a rare condition that may be associated with a variety of diseases.The presenting clinical picture may be very heterogeneous and represent a challenge for the clinician.In the present paper we describe both a common and an uncommon clinical presentation of PCI and review the pertaining literature.Our cases confirm that,apart from asymptomatic cases,the clinical presentation of PCI may be widely different and suggest that a new onset of stipsis might be the presenting symptom.Diagnosis might be suggested by a simple X-ray of the digestive tract showing a change in the characteristics of the intestinal wall in two-thirds of these patients.However,one third of the patients do not have a suggestive X-ray and require a computed tomography(CT) scan/nuclear magnetic resonance that may reveal a thickened bowel wall containing gas to confirm the diagnosis and distinguish PCI from intraluminal air or submucosal fat.CT also allows the detection of additional findings that may suggest an underlying,potentially worrisome cause of PCI such as bowel wall thickening,altered contrast mucosal enhancement,dilated bowel,soft tissue stranding,ascites and the presence of portal air.Our results also point out that clinicians and endoscopists should be aware of the possible presentations of PCI in order to correctly manage the patients affected with this disease and avoid unnecessary surgeries.The increasing number of colonoscopies performed for colon cancer screening makes PCI more frequently casually encountered and/or provoked,therefore the possible endoscopic appearances of this disease should be well known by endoscopists. | Francesco Azzaroli Laura Turco Liza Ceroni Stefania Sartoni Galloni Federica Buonfiglioli Claudio Calvanese Giuseppe Mazzella | 2011 | World Journal of Gastroenterology2011,17,44: | 16 |
