| 1 | 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 |
| 2 | Inflammation in irritable bowel syndrome:Myth or newtreatment target?显示文摘Low-grade intestinal inflammation plays a key role in the pathophysiology of irritable bowel syndrome(IBS), and this role is likely to be multifactorial. The aim of this review was to summarize the evidence on the spectrum of mucosal inflammation in IBS, highlighting the relationship of this inflammation to the pathophysiology of IBS and its connection to clinical practice. We carried out a bibliographic search in Medline and the Cochrane Library for the period of January 1966 to December 2014, focusing on publications describing an interaction between inflammation and IBS. Several evidences demonstrate microscopic and molecular abnormalities in IBS patients. Understanding the mechanisms underlying low-grade inflammation in IBS may help to design clinical trials to test the efficacy and safety of drugs that target this pathophysiologic mechanism. | Emanuele Sinagra Giancarlo Pompei Giovanni Tomasello Francesco Cappello Gaetano Cristian Morreale Georgios Amvrosiadis Francesca Rossi Attilio Ignazio Lo Monte Aroldo Gabriele Rizzo Dario Raimondo | 2016 | World Journal of Gastroenterology2016，22，7： | 16 |
| 3 | Negative capsule endoscopy in patients with obscure gastrointestinal bleeding reliable: Recurrence of bleeding on long-term follow-up显示文摘AIM: To assess the rate of recurrent bleeding of the small bowel in patients with obscure bleeding already undergone capsule endoscopy (CE) with negative results. METHODS: We reviewed the medical records related to 696 consecutive CE performed from December 2002 to January 2011, focusing our attention on patients with recurrence of obscure bleeding and negative CE. Evaluating the patient follow-up, we analyzed the recurrence rate of obscure bleeding in patient with a negative CE. Actuarial rates of rebleeding during follow-up were calculated, and factors associated with rebleeding were assessed through an univariate and multivariate analysis. A P value of less than 0.05 was regarded as statistically significant. The sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of negative CE were calculated. RESULTS: Two hundred and seven out of 696 (29.7%) CE studies resulted negative in patient with obscure/overt gastrointestinal bleeding. Overall, 489 CE (70.2%) were positive studies. The median follow-up was 24 mo (range 12-36 mo). During follow-up, recurrence of obscure bleeding was observed only in 34 out of 207 negative CE patients (16.4%); 26 out of 34 with obscure overt bleeding and 8 out of 34 with obscure occult bleeding. The younger age (< 65 years) and the onset of bleeding such as melena are independent risk factors of rebleeding after a negative CE (OR = 2.6703, 95%CI: 1.1651-6.1202, P = 0.0203; OR 4.7718, 95%CI: 1.9739-11.5350, P = 0.0005). The rebleeding rate (CE+ vs CE-) was 16.4% vs 45.1% (χ 2 test, P = 0.00001). The sensitivity, specificity, and PPV and NPV were 93.8%, 100%, 100%, 80.1%, respectively. CONCLUSION: Patients with obscure gastrointestinal bleeding and negative CE had a significantly lower rebleeding rate, and further invasive investigations can be deferred. | Maria Elena Riccioni Riccardo Urgesi Rossella Cianci Gianluca Rizzo Luca D'Angelo Riccardo Marmo Guido Costamagna | 2013 | World Journal of Gastroenterology2013，19，28： | 14 |
| 4 | Antioxidant properties of glutamine and its role in VEGF-Akt pathways in portal hypertension gastropathy显示文摘AIM: To investigate the effects of glutamine on oxidative/nitrosative stress and the vascular endothelial growth factor (VEGF)-Akt-endothelial nitric oxide synthase (eNOS) signaling pathway in an experimental model of portal hypertension induced by partial portal vein ligation (PPVL). METHODS: Portal hypertension was induced by PPVL. The PPVL model consists of a partial obstruction of the portal vein, performed using a 20 G blunt needle as a guide, which is gently removed after the procedure. PPVL model was performed for 14 d beginning treatment with glutamine on the seventh day. On the fifteenth day, the mesenteric vein pressure was checked and the stomach was removed to test immunoreactivity and oxidative stress markers. We evaluated the expression and the immunoreactivity of proteins involved in the VEGF-Akt-eNOS pathway by Western blotting and immunohistochemical analysis. Oxidative stress was measured by quantification of the cytosolic concentration of thiobarbituric acid reactive substances (TBARS) as well as the levels of total glutathione (GSH), superoxide dismutase (SOD) activity, nitric oxide (NO) production and nitrotyrosine immunoreactivity. RESULTS: All data are presented as the mean ± SE. The production of TBARS and NO was significantly increased in PPVL animals. A reduction of SOD activity was detected in PPVL + G group. In the immunohistochemical analyses of nitrotyrosine, Akt and eNOS, the PPVL group exhibited significant increases, whereas decreases were observed in the PPVL + G group, but no difference in VEGF was detected between these groups. Western blotting analysis detected increased expression of phosphatidylinositol-3-kinase (PI3K), P-Akt and eNOS in the PPVL group compared with the PPVL + G group, which was not observed for the expression of VEGF when comparing these groups. Glutamine administration markedly alleviated oxidative/nitrosative stress, normalized SOD activity, increased levels of total GSH and blocked NO overproduction as well as the formation of peroxynitrite. CONCLUSION: Glutamine treatment demonstrated to reduce oxidative damage but does not reduce angiogenesis induced by PH in gastric tissue, demonstrating a beneficial role for the PI3K-Akt-eNOS pathway. | Camila Marques Francielli Licks Ingrid Zattoni Beatriz Borges Luiz Eduardo Rizzo de Souza Claudio Augusto Marroni Norma Possa Marroni | 2013 | World Journal of Gastroenterology2013，19，28： | 9 |
| 5 | Anti-TNF alpha in the treatment of ulcerative colitis:A valid approach for organ-sparing or an expensive option to delay surgery?显示文摘Ulcerative colitis(UC)is an inflammatory bowel disease affecting large bowel with variable clinical course.The history of disease has been modified by the introduction of biologic therapy,in particular Infliximab(IFX),that has demonstrated efficacy in inducing fast symptoms remission,promoting mucosal healing and maintaining long-term remission.However,surgery is still needed for UC patients:in case of failure of medical therapy and if acute complications or a malignancy occurred.Surgical treatment is associated with a short-term postoperative mortality and morbidity respectively of 0%-4%and 30%.In this study we systematically analyzed:the role of IFX in reducing the colectomy rate,the risk of post-operative morbidity in pre-operatively IFX-treated patients and the cost-effectiveness of IFX therapy.Four of 5 analyzed randomized controlled trials demonstrated that therapy with IFX significantly reduces the colectomy rate.Moreover,pre-operative treatment with IFX doesn’t seem to increase post-operative infectious complications.By an economic point of view,the cost-effectiveness of IFX-therapy was demonstrated for UC patients suffering from moderate to severe UC in a study based on a cost estimation of the National Health Service of England and Wales.However,the argument is debated. | Gianluca Rizzo Daniela Pugliese Alessandro Armuzzi Claudio Coco | 2014 | World Journal of Gastroenterology2014，20，17： | 5 |
| 6 | Immunotherapy and immunoescape in colorectal cancer显示文摘Immunotherapy encompasses a variety of interventions and techniques with the common goal of eliciting tumor cell destructive immune responses. Colorectal carcinoma often presents as metastatic disease that impedes curative surgery. Novel strategies such as active immunization with dendritic cells (DCs), gene transfer of cytokines into tumor cells or administration of immunostimulatory monoclonal antibodies (such as anti-CD137 or anti-CTLA-4) have been assessed in preclinical studies and are at an early clinical development stage. Importantly, there is accumulating evidence that chemotherapy and immunotherapy can be combined in the treatment of some cases with colorectal cancer, with synergistic potentiation as a result of antigens cross-presented by dendritic cells and/or elimination of competitor or suppressive T lymphocyte populations (regulatory T-cells). However, genetic and epigenetic unstable carcinoma cells frequently evolve mechanisms of immunoevasion that are the result of either loss of antigen presentation, or an active expression of immunosuppressive substances. Some of these actively immunosuppressive mechanisms are inducible by cytokines that signify the arrival of an effector immune response. For example, induction of 2, 3 indoleamine dioxygenase (IDO) by IFNγ in colorectal carcinoma cells. Combinational and balanced strategies fostering antigen presentation, T-cell costimulation and interference with immune regulatory mechanisms will probably take the stage in translational research in the treatment of colorectal carcinoma. | Guillermo Mazzolini Oihana Murillo Catalina Atorrasagasti Juan Dubrot Iigo Tirapu Miguel Rizzo Ainhoa Arina Carlos Alfaro Arantza Azpilicueta Carmen Berasain José L Perez-Gracia Alvaro Gonzalez Ignacio Melero | 2007 | World Journal of Gastroenterology2007，13，44： | 4 |

| 9 | Current status of the adjuvant therapy in uterine sarcoma: A literature review显示文摘Uterine sarcomas (US) are rare mesenchymal tumours accounting approximately for 3%–7% of all uterine cancers. Histologically, US are classified into mesenchymal tumours or mixed epithelial and mesenchymal tumours. The group of mesenchymal tumours includes uterine leiomyosarcoma (uLMS, 65% of cases), endometrial stromal sarcoma (ESS, 21%)– traditionally divided into low grade (LG-ESS) and high grade–undifferentiated uterine sarcoma (5%) and other rare subtypes such as alveolar or embryonal rhabdomyosarcoma. Despite the fact that several drugs demonstrated clinical activity in advanced or metastatic settings, the role of postoperative therapy in US remains controversial. In this review, we have summarised the current state of the art, including the chief trials on adjuvant treatment modalities in US, especially focusing on uLMS, LG-ESS and other rare histotypes. | Alessandro Rizzo Maria Abbondanza Pantaleo Maristella Saponara Margherita Nannini | 2019 | World Journal of Clinical Cases2019，7，14： | 3 |
| 10 | Impact of HLA-G analysis in prevention, diagnosis and treatment of pathological conditions显示文摘Human leukocyte antigen-G(HLA-G) is a non-classical HLA class Ⅰ molecule that differs from classical HLA class Ⅰ molecules by low polymorphism and tissue distribution. HLA-G is a tolerogenic molecule with an immune-modulatory and anti-inflammatory function on both innate and adaptative immunity. This peculiar characteristic of HLA-G has led to investigations of its role in pathological conditions in order to define possible uses in diagnosis, prevention and treatment. In recent years, HLA-G has been shown to have an important implication in different inflammatory and autoimmune diseases, pregnancy complications, tumor development and aggressiveness, and susceptibility to viral infections. In fact, HLA-G molecules have been reported to alternate at both genetic and protein level in different disease situations, supporting its crucial role in pathological conditions. Specific pathologies show altered levels of soluble(s)HLA-G and different HLA-G gene polymorphisms seem to correlate with disease. This review aims to update scientific knowledge on the contribution of HLA-G in managing pathological conditions. | Daria Bortolotti Valentina Gentili Antonella Rotola Enzo Cassai Roberta Rizzo Dario Di Luca | 2014 | World Journal of Methodology2014，4，1： | 3 |

| 15 | Ventricular repolarization measures for arrhythmic risk stratification显示文摘Ventricular repolarization is a complex electrical phenomenon which represents a crucial stage in electrical cardiac activity. It is expressed on the surface electrocardiogram by the interval between the start of the QRS complex and the end of the T wave or U wave(QT). Several physiological, pathological and iatrogenic factors can influence ventricular repolarization. It has been demonstrated that small perturbations in this process can be a potential trigger of malignant arrhythmias, therefore the analysis of ventricular repolarization represents an interesting tool to implement risk stratification of arrhythmic events in different clinical settings. The aim of this review is to critically revise the traditional methods of static analysis of ventricular repolarization as well as those for dynamic evaluation, their prognostic significance and the possible application in daily clinical practice. | Francesco Monitillo Marta Leone Caterina Rizzo Andrea Passantino Massimo Iacoviello | 2016 | World Journal of Cardiology2016，8，1： | 2 |

| 17 | Potential Use of a Poultry Manure Digestate as a Biofertiliser:Evaluation of Soil Properties and Lactuca sativa Growth显示文摘Anaerobic digestion is a process that is widely used for the treatment of organic wastes. The digestate can be used as a soil amendment or crop fertiliser. The aims of our work were to evaluate 1) the physicochemical composition and pathogen content in a digestate from poultry manure, according to international regulations, and 2) the effect of its soil application on the major chemical and biological soil properties and on the growth of Lactuca sativa. The experiment consisted of two groups of pots(with and without crop). Treatments applied to each group were as follows: low and high doses of digestate and inorganic fertiliser, and no application(control)(low dose: 70 kg nitrogen(N) ha^(-1) and 21 kg phosphorus(P) ha^(-1); high dose: 210 kg N ha^(-1) and 63 kg P ha^(-1)). Soil samples were taken 7 and 34 d(harvest) after treatment applications. Heavy metal and pathogen contents in the digestate were below the upper limit values. Despite the high pH and electrical conductivity values of the digestate, both soil parameters presented acceptable values for crop growth. Although there were no initial increases in total inorganic N and available P in soil with digestate application, an increase in the fresh weight of crop was observed with the high dose application. This is probably associated with the slow nutrient release from the digestate during the development of the crop. Changes in the microbial community were temporary and occurred at the initial sampling stage of the experiment. | Natalia MóRTOLA Romina ROMANIUK Vanina COSENTINO Maximiliano EIZA Patricia CARFAGNO Pedro RIZZO Patricia BRES Nicolás RIERA Marcos ROBA Mariano BUTTI Daiana SAINZ Lucrecia BRUTTI | 2019 | Pedosphere2019，29，1： | 2 |
