| 1 | Portal vein thrombosis:Insight into physiopathology,diagnosis,and treatment显示文摘Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a patient's outcome. In this review, we analyze the physiopathological mechanisms of PVT development, together with the hemodynamic and functional alterations related to this condition. Moreover, we describe the principal factors most frequently involved in PVT development and the recent knowledge concerning diagnostic and therapeutic procedures. Finally, we analyze the implications of PVT in the setting of liver transplantation and its possible influence on patients' future prognoses. | Francesca R Ponziani Maria A Zocco Chiara Campanale Emanuele Rinninella Annalisa Tortora Luca Di Maurizio Giuseppe Bombardieri Raimondo De Cristofaro Anna M De Gaetano Raffaele Landolfi Antonio Gasbarrini | 2010 | World Journal of Gastroenterology2010，16，2： | 75 |
| 2 | FAIR Principles:Interpretations and Implementation Considerations显示文摘The FAIR principles have been widely cited,endorsed and adopted by a broad range of stakeholders since their publication in 2016.By intention,the 15 FAIR guiding principles do not dictate specific technological implementations,but provide guidance for improving Findability,Accessibility,Interoperability and Reusability of digital resources.This has likely contributed to the broad adoption of the FAIR principles,because individual stakeholder communities can implement their own FAIR solutions.However,it has also resulted in inconsistent interpretations that carry the risk of leading to incompatible implementations.Thus,while the FAIR principles are formulated on a high level and may be interpreted and implemented in different ways,for true interoperability we need to support convergence in implementation choices that are widely accessible and(re)-usable.We introduce the concept of FAIR implementation considerations to assist accelerated global participation and convergence towards accessible,robust,widespread and consistent FAIR implementations.Any self-identified stakeholder community may either choose to reuse solutions from existing implementations,or when they spot a gap,accept the challenge to create the needed solution,which,ideally,can be used again by other communities in the future.Here,we provide interpretations and implementation considerations(choices and challenges)for each FAIR principle. | Annika Jacobsen Ricardo de Miranda Azevedo Nick Juty Dominique Batista Simon Coles Ronald Cornet Melanie Courtot Merce Crosas Michel Dumontier Chris T.Evelo Carole Goble Giancarlo Guizzardi Karsten Kryger Hansen Ali Hasnain Kristina Hettne Jaap Heringa Rob W.W.Hooft Melanie Imming Keith G.Jeffery Rajaram Kaliyaperumal Martijn GKersloot Christine R.Kirkpatrick Tobias Kuhn Ignasi Labastida Barbara Magagna PeterMcQuilton Natalie Meyers Annalisa Montesanti Mirjam van Reisen Philippe Rocca-Serra Robert Pergl Susanna-Assunta Sansone Luiz Olavo Bonino da Silva Santos Juliane Schneider George Strawn Mark Thompson Andra Waagmeester Tobias Weigel Mark D.Wilkinson Egon L.Willighagen Peter Wittenburg Marco Roos Barend Mons Erik Schultes | 2020 | Data Intelligence2020，2，1： | 26 |
| 3 | MicroRNAs as possible biomarkers for diagnosis and prognosis of hepatitis b- and c-related-hepatocellularcarcinoma显示文摘Aim of the present review is to summarize the current knowledge about the potential relationship between mi RNAs and hepatitis B virus(HBV)-hepatitis C virus(HCV) related liver diseases. A systematic computerbased search of published articles, according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis Statement, was performed to identify relevant studies on usefulness of serum/plasma/urine mi RNAs, as noninvasive biomarkers for early detection of HBV and HCV-induced hepatocellular carcinoma(HCC) development, as well as for its prognostic evaluation. The used Medical Subject Headings terms and keywords were: 'HBV', 'HCV', 'hepatocellular carcinoma', 'micro RNAs', 'mi RNAs', 'diagnosis', 'prognosis', 'therapy', 'treatment'. Some serum/plasma mi RNAs, including mi R-21, mi R-122, mi-125a/b, mi R-199a/b, mi R-221, mi R-222, mi R-223, mi R-224 might serve as biomarkers for early diagnosis/prognosis of HCC, but, to date, not definitive results or well-defined panels of mi RNAs have been obtained. More well-designed studies, focusing on populations of different geographical areas and involving larger series of patients, should be carried out to improve our knowledge on the potential role of mi RNAs for HCC early detection and prognosis. | Sirio Fiorino Maria Letizia Bacchi-Reggiani Michela Visani Giorgia Acquaviva Adele Fornelli Michele Masetti Andrea Tura Fabio Grizzi Matteo Zanello Laura Mastrangelo Raffaele Lombardi Luca Di Tommaso Arrigo Bondi Sergio Sabbatani Andrea Domanico Carlo Fabbri Paolo Leandri Annalisa Pession Elio Jovine Dario de Biase | 2016 | World Journal of Gastroenterology2016，22，15： | 25 |
| 4 | H pylori infection and systemic antibodies to CagA and heat shock protein 60 in patients with coronary heart disease显示文摘AIM: To determine the overall prevalence of H pylori and CagA positive H pylori infection and the prevalence of other bacterial and viral causes of chronic infection in patients with coronary heart disease (CHD), and the potential role of anti-heat-shock protein 60 (Hsp60) anti- body response to these proteins in increasing the risk of CHD development. METHODS: Eighty patients with CHD and 160 controls were employed. We also compared the levels of anti- heat-shock protein 60 (Hsp60) antibodies in the two groups. The H pylori infection and the CagA status were determined serologically, using commercially available enzyme-linked immunosorbent assays (ELISA), and a Western blotting method developed in our laboratory. Systemic antibodies to Hsp60 were determined by a sandwich ELISA, using a polyclonal antibody to Hsp60 to sensitise polystyrene plates and a commercially available human Hsp60 as an antigen. RESULTS: The overall prevalence of H pylori infec- tion was 78.7% (n = 63) in patients and 76.2% (n = 122) in controls (P = 0.07). Patients infected by CagA- positive (CagA+) H pylori strains were 71.4% (n = 45) vs 52.4% of infected controls (P = 0.030, OR = 2.27). Sys-temic levels of IgG to Hsp60 were increased in H pylori- negative patients compared with uninfected controls (P < 0.001) and CagA-positive infected patients compared with CagA-positive infected controls (P = 0.007). CONCLUSION: CagA positive H pylori infection may concur to the development of CHD; high levels of anti- Hsp60 antibodies may constitute a marker and/or a con- comitant pathogenic factor of the disease. | Cristina Lenzi Alberto Palazzuoli Nicola Giordano Giuliano Alegente Catia Gonnelli Maria Stella Campagna Annalisa Santucci Michele Sozzi Panagiotis Papakostas Fabio Rollo Ranuccio Nuti Natale Figura | 2006 | World Journal of Gastroenterology2006，12，48： | 23 |
| 5 | Giant cavernous liver hemangiomas: is it the time to change the size categories?显示文摘BACKGROUND: Four different sizes(4, 5, 8 and 10 cm in diameter) can be found in the literature to categorize a liver hemangioma as giant. The present review aims to clarify the appropriateness of the size category 'giant' for liver hemangioma.DATA SOURCES: We reviewed the reports on the categorization of hemangioma published between 1970 and 2014. The number of hemangiomas, size criteria, mean and range of hemangioma sizes, and number of asymptomatic and symptomatic patients were investigated in patients aged over 18 years. Liver hemangiomas were divided into four groups: <5.0 cm, 5.0-9.9 cm, 10.0-14.9 cm and ≥15.0 cm in diameter. Inclusion criteria were noted in 34 articles involving 1972(43.0%) hemangiomas(>4.0 cm).RESULTS: The patients were divided into the following groups: 154 patients(30.0%) with hemangiomas less than 5.0 cm in diameter(small), 182(35.5%) between 5.0 cm and 9.9 cm(large), 75(14.6%) between 10.0 and 14.9 cm(giant), and 102(19.9%) more than 15.0 cm(enormous). There were 786(39.9%) asymptomatic patients and 791(40.1%) symptomatic patients. Indications for surgery related to symptoms were reported in only 75(3.8%) patients. Operations including 137 non-anatomical resection(12.9%) and 469 enucleation(44.1%) were unclearly related to size and symptoms.CONCLUSIONS: The term 'giant' seems to be justified for liver hemangiomas with a diameter of 10 cm. Hemangiomas categorized as 'giant' are not indicated for surgery. Surgery should be performed only when other symptoms are apparent. | isidoro di carlo renol koshy saif al mudares annalisa ardiri gaetano bertino adriana toro | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，1： | 22 |
| 6 | Management of small hepatocellular carcinoma in cirrhosis:Focus on portal hypertension显示文摘The incidence of hepatocellular carcinoma(HCC) is rising worldwide being currently the fifth most common cancer and third cause of cancer-related mortality.Early detection of HCC through surveillance programs have enabled the identification of small nodules with higher frequency,and nowadays account for 10%-15% of patients diagnosed in the West and almost 30% in Japan.Patients with small HCC can be candidates for potential curative treatments:liver transplantation,surgical resection and percutaneous ablation,depending on the presence of portal hypertension and co-morbidities.This review will analyze recent advancements in the clinical management of these individuals,focusing on issues related to the role of portal hypertension,the debate between resection and ablative therapies and the future impact of molecular technologies. | Virginia Hernandez-Gea Fanny Turon Annalisa Berzigotti Augusto Villanueva | 2013 | World Journal of Gastroenterology2013，19，8： | 20 |
| 7 | role of microRNAs in the main molecular pathways of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the most common primary liver malignant neoplasia. HCC is characterized by a poor prognosis. The need to find new molecular markers for its diagnosis and prognosis has led to a progressive increase in the number of scientific studies on this topic. MicroRNAs(miRNAs) are small noncoding RNA that play a role in almost all main cellular pathways. miRNAs are involved in the regulation of expression of the major tumor-related genes in carcinogenesis, acting as oncogenes or tumor suppressor genes. The aim of this review was to identify papers published in 2017 investigating the role of miRNAs in HCC tumorigenesis. miRNAs were classified according to their role in the main molecular pathways involved in HCC tumorigenesis:(1) m TOR;(2) Wnt;(3) JAK/STAT;(4) apoptosis; and(5) MAPK. The role of miRNAs in prognosis/response prediction was taken into consideration. Bearing in mind that the analysis of miRNAs in serum and other body fluids would be crucial for clinical management, the role of circulating miRNAs in HCC patients was also investigated. The most represented mi RNA-regulated pathway in HCC is m TOR, but apoptosis, Wnt, JAK/STAT or MAPK pathways are also influenced by mi RNA expression levels. These miRNAs could thus be used in clinical practice as diagnostic, prognostic or therapeutic targets for HCC treatment. | Francesco Vasuri Michela Visani Giorgia Acquaviva Thomas Brand Michelangelo Fiorentino Annalisa Pession Giovanni Tallini Antonia D’Errico Dario de Biase | 2018 | World Journal of Gastroenterology2018，24，25： | 16 |
| 8 | Chemokine and chemotactic signals in dendritic cell migration显示文摘Dendritic cells (DCs) are professional antigen-presenting cells responsible for the activation of specific T-cell responses and for thedevelopment of immune tolerance. Immature DCs reside in peripheral tissues and specialize in antigen capture, whereas matureDCs reside mostly in the secondary lymphoid organs where they act as antigen-presenting cells. The correct localization of DCs isstrictly regulated by a large variety of chemotactic and nonchemotactic signals that include bacterial products, DAMPs (dangerassociated molecular patterns), complement proteins, lipids, and chemokines. These signals function both individually and inconcert, generating a complex regulatory network. This network is regulated at multiple levels through different strategies, such assynergistic interactions, proteolytic processing, and the actions of atypical chemokine receptors. Understanding this complexscenario will help to clarify the role of DCs in different pathological conditions, such as autoimmune diseases and cancers and willuncover new molecular targets for therapeutic interventions. | Laura Tiberio Annalisa Del Prete Tiziana Schioppa Francesca Sozio Daniela Bosisio Silvano Sozzani | 2018 | Cellular & Molecular Immunology2018，15，4： | 14 |
| 9 | Role of Helicobacter pylori infection on nutrition and metabolism显示文摘Helicobacter pylori(H. pylori) is a gram-negative pathogen that is widespread all over the world, infecting more than 50% of the world's population. It is etiologically associated with non-atrophic and atrophic gastritis, peptic ulcer and shows a deep association with primary gastric B-cell lymphoma and gastric adenocarcinoma. Recently, the medical research focused on the modification of the gastric environment induced by H. pylori infection, possibly affecting the absorption of nutrients and drugs as well as the production of hormones strongly implicated in the regulation of appetite and growth. Interestingly, the absorption of iron and vitamin B12 is impaired by H. pylori infection, while infected subjects have lower basal and fasting serum levels of ghrelin and higher concentration of leptin compared to controls. Since leptin is an anorexigenic hormone, and ghrelin stimulates powerfully the release of growth hormone in humans, H. pylori infection may finally induce growth retardation if acquired very early in the childhood and in malnourished children. This review is focused on the nutritional effects of H. pylori infection, such as the reduced bioavailability or the malabsorbption of essential nutrients, and of gastrointestinal hormones, as well as on the relationship between H. pylori and the metabolic syndrome. | Francesco Franceschi Tortora Annalisa Di Rienzo Teresa D'Angelo Giovanna Gianluca Ianiro Scaldaferri Franco Gerardi Viviana Tesori Valentina Lopetuso Loris Riccardo Gasbarrini Antonio | 2014 | World Journal of Gastroenterology2014，20，36： | 11 |
| 10 | Endoscopic features of gastro-intestinal lymphomas: From diagnosis to follow-up显示文摘Many progresses have been done in the management of gastrointestinal(GI) lymphomas during last decades, especially after the discovery of Helicobacter pylori-dependent lymphoma development. The stepwise implementation of new endoscopic techniques, by means of echoendoscopy or double-balloon enteroscopy, enabled us to more precisely describe the endoscopic features of GI lymphomas with substantial contribution in patient management and in tailoring the treatment strategy with organ preserving approaches. In this review, we describe the recent progresses in GI lymphoma management from disease diagnosis to follow-up with a specific focus on the endoscopic presentation according to the involved site and the lymphoma subtype. Additionally, new or emerging endoscopic technologies that have an impact on the management of gastrointestinal lymphomas are reported. We here discuss the two most common subtypes of GI lymphomas: the mucosaassociated lymphoid tissue and the diffuse large B cell lymphoma. A general outline on the state-of-the-art of the disease and on the role of endoscopy in both diagnosis and follow-up will be performed. | Calogero Vetro Alessandra Romano Irene Amico Concetta Conticello Giovanna Motta Amalia Figuera Annalisa Chiarenza Cosimo Di Raimondo Giorgio Giulietti Giacomo Bonanno Giuseppe Alberto Palumbo Francesco Di Raimondo | 2014 | World Journal of Gastroenterology2014，20，36： | 10 |
| 11 | Chronic hepatitis C:This and the new era of treatment显示文摘Over the last years it has started a real revolution in the treatment of chronic hepatitis C. This occurred for the availability of direct-acting antiviral agents that allow to reach sustained virologic response in approximately 90% of cases. In the near future further progress will be achieved with the use of pan-genotypic drugs with high efficacy but without side effects. | Gaetano Bertino Annalisa Ardiri Maria Proiti Giuseppe Rigano Evelise Frazzetto Shirin Demma MariaIrene Ruggeri Laura Scuderi Giulia Malaguarnera Nicoletta Bertino Venerando Rapisarda Isidoro Di Carlo Adriana Toro Federico Salomone Mariano Malaguarnera Emanuele Bertino Michele Malaguarnera | 2016 | World Journal of Hepatology2016，8，2： | 10 |
| 12 | In-vitro corrosion of AZ31 magnesium alloys by using a polydopamine coating显示文摘Magnesium alloys are candidates to be used as biodegradable biomaterials for producing medical device.Their use is restricted due to the high degradation rate in physiological media.To contribute to solving this problem,a polydopamine(PDOPA)layer could be used to increase adhesion between the metallic substrate and external organic coating.In this paper,the corrosion behaviour of samples was investigated to determine their performance during the long-term exposure in simulated body fluid.Electrochemical methods including Open Circuit Potential(OCP)and Electrochemical Impedance Spectroscopy(EIS)were used to investigate the corrosion resistance of samples.The results demonstrated a decreasing of the substrate degradation rate when PDOPA was used as interlayer supposing a synergistic effect when it was used together with the organic coating. | Anna Carangelo Annalisa Acquesta Tullio Monetta | 2019 | Bioactive Materials2019，4，1： | 9 |
| 13 | Helicobacter pylori's virulence and infection persistence define pre-eclampsia complicated by fetal growth retardation显示文摘AIM: To better understand the pathogenic role of Helicobacter pylori (H. pylori) in pre-eclampsia (PE), and whether it is associated or not with fetal growth retardation (FGR). METHODS: Maternal blood samples were collected from 62 consecutive pregnant women with a diagnosis of PE and/or FGR, and from 49 women with uneventful pregnancies (controls). Serum samples were evaluated by immunoblot assay for presence of specific antibodies against H. pylori antigens [virulence: cytotoxin-associated antigen A (CagA); ureases; heat shock protein B; flagellin A; persistence: vacuolating cytotoxin A (VacA)]. Maternal complete blood count and liver enzymes levels were assessed at delivery by an automated analyzer. RESULTS: A significantly higher percentage of H. pyloriseropositive women were found among PE cases (85.7%) compared to controls (42.9%, P < 0.001). There were no differences between pregnancies complicated by FGR without maternal hypertension (46.2%) and controls. Importantly, persistent and virulent infections (VacA/ CagA seropositive patients, intermediate leukocyte blood count and aspartate aminotransferase levels) were exclusively associated with pre-eclampsia complicated by FGR, while virulent but acute infections (CagA positive/ VacA negative patients, highest leukocyte blood count and aspartate aminotransferase levels) specifically correlated with PE without FGR. CONCLUSION: Our data strongly indicate that persistent and virulent H. pylori infections cause or contribute to PE complicated by FGR, but not to PE without feto-placental compromise. | Simona Cardaropoli Alessandro Rolfo Annalisa Piazzese Antonio Ponzetto Tullia Todros | 2011 | World Journal of Gastroenterology2011，17，47： | 9 |
| 14 | MicroRNAs as controlled systems and controllers in non-alcoholic fatty liver disease显示文摘Non-alcoholic fatty liver disease(NAFLD) is a multi-faceted condition including simple steatosis alone or associated with inflammation and ballooning(non-alcoholic steatohepatitis) and eventually fibrosis.The NAFLD incidence has increased over the last twenty years becoming the most frequent chronic liver disease in industrialized countries.Obesity,visceral adiposity,insulin resistance,and many other disorders that characterize metabolic syndrome are the major predisposing risk factors for NAFLD.Furthermore,different factors,including genetic background,epigenetic mechanisms and environmental factors,such as diet and physical exercise,contribute to NAFLD development and progression.Several lines of evidence demonstrate that specific microRNAs expression profiles are strongly associated with several pathological conditions including NAFLD.In NAFLD,microRNA deregulation in response to intrinsic genetic or epigenetic factors or environmental factors contributes to metabolic dysfunction.In this review we focused on microRNAs role both as controlled and controllers molecules in NAFLD development and/or their eventual value as non-invasive biomarkers of disease. | Nadia Panera Daniela Gnani Annalisa Crudele Sara Ceccarelli Valerio Nobili Anna Alisi | 2014 | World Journal of Gastroenterology2014，20，41： | 9 |
| 15 | Outcome of nonerosive gastro-esophageal reflux disease patients with pathological acid exposure显示文摘AIM: To assess the management and outcome of nonerosive gastro-esophageal reflux disease (NERD) patients who were identified retrospectively, after a 5-year follow-up.METHODS: We included patients with gastro-esophageal reflux disease (GERD) symptoms who had a negative endoscopy result and pathological 24-h esophageal pH-monitoring while off therapy. We interviewed them after an average period of 5 years (range 3.5-7 years) by means of a structured questionnaire to assess presence of GERD symptoms, related therapy, updated en-doscopic data and other features. We assessed predictors of esophagitis development by means of univariate and multivariate statistical analysis.RESULTS: 260 patients (137 women) were included. Predominant GERD symptoms were heartburn andregurgitation in 103/260 (40%). 70% received a maintenance treatment, which was proton pump inhibitor (PPI) in 55% of cases. An average number of 1.5 symptomatic relapses per patient/year of follow-up were observed. A progression to erosive gastro-esophageal reflux disease (ERD) was found in 58/193 (30.0%) of patients undergoing repeat endoscopy; 72% of these were Los Angeles grade A-B. CONCLUSION: This study shows that progression to ERD occurs in about 5% of NERD cases per year, despite therapy. Only two factors consistently and independently influence progression: smoking and absence of PPI therapy. | Fabio Pace Stefano Pallotta Gianpiero Manes Annalisa de Leone Patrizia Zentilin Luigi Russo Vincenzo Savarino Matteo Neri Enzo Grossi Rosario Cuomo | 2009 | World Journal of Gastroenterology2009，15，45： | 8 |

| 17 | Malignant gastric outlet obstruction:Which is the best therapeutic option?显示文摘Malignant gastric outlet obstruction(MGOO)is a clinical condition characterized by the mechanical obstruction of the pylorus or the duodenum due to tumor compression/infiltration,with consequent reduction or impossibility of an adequate oral intake.MGOO is mainly secondary to advanced pancreatic or gastric cancers,and significantly impacts on patients’survival and quality of life.Patients suffering from this condition often present with intractable vomiting and severe malnutrition,which further compromise therapeutic chances.Currently,palliative strategies are based primarily on surgical gastrojejunostomy and endoscopic enteral stenting with self-expanding metal stents.Several studies have shown that surgical approach has the advantage of a more durable relief of symptoms and the need of fewer re-interventions,at the cost of higher procedure-related risks and longer hospital stay.On the other hand,enteral stenting provides rapid clinical improvement,but have the limit of higher stent dysfunction rate due to tumor ingrowth and a subsequent need of frequent reinterventions.Recently,a third way has come from interventional endoscopic ultrasound,through the development of endoscopic ultrasound-guided gastroenterostomy technique with lumen-apposing metal stent.This new technique may ideally encompass the minimal invasiveness of an endoscopic procedure and the long-lasting effect of the surgical gastrojejunostomy,and brought encouraging results so far,even if prospective comparative trial are still lacking.In this Review,we described technical aspects and clinical outcomes of the above-cited therapeutic approaches,and discussed the open questions about the current management of MGOO. | Edoardo Troncone Alessandro Fugazza Annalisa Cappello Giovanna Del Vecchio Blanco Giovanni Monteleone Alessandro Repici Anthony Yuen Bun Teoh Andrea Anderloni | 2020 | World Journal of Gastroenterology2020，26，16： | 7 |
| 18 | Role of nitric oxide in the impairment of circular muscle contractility of distended, uninflamed mid-colon in TNBS-induced acute distal colitis in rats显示文摘AIM: To evaluate the role of nitric oxide (NO) in the motor disorders of the dilated uninflamed mid-colon (DUMC)from trinitrobenzene sulfonic acid (TNBS)-induced acute distal colitis in rats.METHODS: Colitis was induced in male Sprague-Dawley rats by a single intracolonic administration of TNBS.Control rats received an enema of 0.9% saline. The rats were killed 48 h after TNBS or saline administration.Macroscopic and histologic lesions of the colon were evaluated. Myeloperoxidase (MPO) and nitric oxide synthase (NOS) activity were measured on the colonic tissue. In TNBS rats, we evaluated spontaneous and evoked contractile activity in circular muscle strips derived from DUMC in comparison to the same colonic segment of control rats, both in the presence and in the absence of a non-selective NOS isoforms inhibitor N-nitro-Larginine (L-NNA). Pharmacological characterization of electric field stimulation (EFS)-evoked contractile responses was also performed.RESULTS: In TNBS rats, the distal colon showed severe histological lesions and a high MPO activity, while the DUMC exhibited normal histology and MPO activity.Constitutive NOS activity was similar in TNBS and control rats, whereas inducible NOS activity was significantly increased only in the injured distal colon of TNBS rats.Isometrically recorded mechanical activity of circular muscle strips from DUMC of TNBS rats showed a marked reduction of the force and frequency of spontaneous contractions compared to controls, as well as of the contractile responses to a contracting stimulus. In the presence of L-NNA, the contractile activity and responses displayed a significantly greater enhancement compared to controls. The pharmacological characterization of EFS contractile responses showed that a cooperative-like interaction between cholinergic muscarinic and tachykinergic neurokinin 1 and 2 receptors mediated transmission in DUMC of TNBS rats vs a simple additive interaction in controls.CONCLUSION: The results of this study show that, during TNBS-induced acute distal colitis, circular muscle intrinsic contractile mechanisms and possible enteric neural excitatory activity are inhibited in the distended uninflamed mid-colon. Suppression of NO synthesis markedly improves spontaneous and evokes muscle contractions, in spite of any evident change in local NO activity. | Luciano Onori Annalisa Aggio Simona D'Alo' Paola Muzi Maria Grazia Cifone Gabriella Mellillo Rachele Ciccocioppo Gennaro Taddei Giuseppe Frieri Giovanni Latella | 2005 | World Journal of Gastroenterology2005，11，36： | 7 |

| 20 | H pylori status and angiogenesis factors in human gastric carcinoma显示文摘AIM: To investigate H pylori expression in gastric cancer patients in relation to primary tumor angiogenic markers, such as microvessel density (MVD), thymidine phospho- rylase (TP), vascular endothelial growth factor receptor-1 (VEGF-R1), p53 and circulating VEGF levels. METHODS: Angiogenic markers were analyzed immu- nohistochemically in 56 primary gastric cancers. H pylori cytotoxin (vacA) and the cytotoxin-associated gene (cagA) amplification were evaluated using PCR assay. Serum H pylori IgG antibodies and serum/plasma circulating VEGF levels were detected in 39 and 38 patients by ELI- SA, respectively. RESULTS: A total of 69% of patients were positive for circulating IgG antibodies against H pylori. cagA-positive H pylori strains were found in 41% of gastric patients. vacA was found in 50% of patients; s1 strains were more highly expressed among vacA-positive patients. The presence of the s1 strain was signifi cantly associ- ated with cagA (P = 0.0001). MVD was signifi cantly cor- related with both tumor VEGF expression (r = 0.361, P = 0.009) and serum VEGF levels (r = -0.347, P = 0.041).Conversely, neither VEGF-R1 expression nor MVD was related to p53 expression. However, H pylori was not related to any angiogenic markers except for the plasma VEGF level (P = 0.026). CONCLUSION: H pylori antigen is related to higher plasma VEGF levels, but not to angiogenic character- istics. It can be hypothesized that the toxic effects of H pylori on angiogenesis occurs in early preclinical dis- ease phase or in long-lasting aggressive infections, but only when high H pylori IgG levels are persistent. | Anita Mangia Annalisa Chiriatti Girolamo Ranieri Ines Abbate Maria Coviello Giovanni Simone Francesco Alfredo Zito Severino Montemurro Antonello Rucci Alfredo Di Leo Stefania Tommasi Pasquale Berloco Jian Ming Xu Angelo Paradiso | 2006 | World Journal of Gastroenterology2006，12，34： | 5 |
