1Loss of interstitial cells of Cajal network in severe idiopathic gastroparesis显示文摘AIM: To report a case of severe idiopathic gastroparesis in complete absence of Kit-positive gastric interstitial cells of Cajal (ICC). METHODS: Gastric tissue from a patient with severe idiopathic gastroparesis unresponsive to medical treatment and requiring surgery was analyzed by conventional histology and immunohistochemistry. RESULTS: Gastric pacemaker cells expressing Kit receptor had completely disappeared while the local level of stem cell factor, the essential ligand for its development and maintenance, was increased. No signs of cell death were observed in the pacemaker region. CONCLUSION: These results are consistent with the hypothesis that a lack of Kit expression may lead to impaired functioning of ICC. Total gastrectomy proves to be curative.Edda Battaglia Gabrio Bassotti Graziella Bellone Luca Dughera Anna Maria Serra Luigi Chiusa Alessandro Repici Pierroberto Mioli Giorgio Emanuelli 2006World Journal of Gastroenterology2006,12,38:20
2Progress of Solar Wind Magnetosphere Ionosphere Link Explorer(SMILE) Mission显示文摘SMILE(Solar wind Magnetosphere Ionosphere Link Explorer) mission is a joint ESA-CAS space science project. The working orbit is a 19 Re 5000 km HEO with 4 scientific instruments: Soft X-ray Imager(SXI), Ultra-Violet Imager(UVI), Magnetometer(MAG) and Light Ion Analyzer(LIA). SMILE aims to understand the interaction between the solar wind and the Earth's magnetosphere through the images of SXI and UVI and in-situ measurement from LIA and MAG. After the kick-off in 2016, the SMILE project went to Phase A study. The mission adoption is scheduled for November 2018, with a target launch date in 2022–2023.In this paper, the background of the mission, scientific objectives, the design and characteristics of scientific instruments and the mission outline will be introduced in details.WANG Chi BRANDUARDI-RAYMOND Graziella 2018空间科学学报2018,38,5:14
3Crohn's disease and growth deficiency in children and adolescents显示文摘Nutritional concerns, linear growth deficiency, and delayed puberty are currently detected in up to 85% of patients with Crohn's disease(CD) diagnosed at childhood. To provide advice on how to assess and manage nutritional concerns in these patients, a Medline search was conducted using 'pediatric inflammatory bowel disease', 'pediatric Crohn's disease', 'linear growth','pubertal growth', 'bone health', and 'vitamin D' as key words. Clinical trials, systematic reviews, and metaanalyses published between 2008 and 2013 were selected to produce this narrative review. Studies referring to earlier periods were also considered if the data was relevant to our review. Although current treatment strategies for CD that include anti-tumor necrosis factor-αtherapy have been shown to improve patients' growth rate, linear growth deficiencies are still common. In pediatric CD patients, prolonged diagnostic delay, high initial activity index, and stricturing/penetrating typeof behavior may cause growth deficiencies(in weight and height) and delayed puberty, with several studies reporting that these patients may not reach an optimal bone mass. Glucocorticoids and inflammation inhibit bone formation, though their impact on skeletal modeling remains unclear. Long-term control of active inflammation and an adequate intake of nutrients are both fundamental in promoting normal puberty. Recent evidence suggests that recombinant growth factor therapy is effective in improving short-term linear growth in selected patients, but is of limited benefit for ameliorating mucosal disease and reducing clinical disease activity. The authors conclude that an intense initial treatment(taking a 'top-down' approach, with the early introduction of immunomodulatory treatment) may be justified to induce and maintain remission so that the growth of children with CD can catch up, ideally before puberty. Exclusive enteral nutrition has a key role in inducing remission and improving patients' nutritional status.Marco Gasparetto Graziella Guariso 2014World Journal of Gastroenterology2014,20,37:8
4胃的癌症的多模式的治疗显示文摘 Gastric cancer is the second leading cause of death from malignant disease worldwide.Although complete surgical resection remains the only curative modality for early stage gastric cancer,surgery alone only provides long-term survival in 20%of patients with advancedstage disease.To improve current results,it is necessary to consider multimodality treatment,including chemotherapy,radiotherapy and surgery.Recent clinical trials have shown survival benefit of combining different neoadjuvant or adjuvant protocols compared with surgery with curative intent.Furthermore,the implementation of chemotherapy with novel targeted agents could play an important role in the multimodal management of advanced gastric cancer.In this paper,we focus on a multidisciplinary approach in the treatment of gastric cancer and discuss future strategies to improve the outcome for these patients.Ilaria Proserpio Stefano Rausei Sabrina Barzaghi Francesco Frattini Federica Galli Domenico Iovino Francesca Rovera Luigi Boni Gianlorenzo Dionigi Graziella Pinotti 2014World Journal of Gastrointestinal Surgery2014,6,4:8
5Italian survey on non-steroidal anti-inflammatory drugsand gastrointestinal bleeding in children显示文摘AIM: To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug(NSAIDs) use in children.METHODS: A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber(physician or selfmedication) were examined. RESULTS: Fifty-one patients, including 34 males, were enrolled(median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients(68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients(56.9%)]. Seven patients had positive family history of Helicobacter pylori(H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four(47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom(33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51(62%) patients, duodenal lesions in 17(33%) and esophageal lesions in 8(15%). In 10/51(19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight(94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51(6%) patients, an endoscopic hemostasis was needed.CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common inSabrina Cardile Massimo Martinelli Arrigo Barabino Paolo Gandullia Salvatore Oliva Giovanni Di Nardo Luigi Dall'Oglio Francesca Rea Gian Luigi de'Angelis Barbara Bizzarri Graziella Guariso Enzo Masci Annamaria Staiano Erasmo Miele Claudio Romano 2016World Journal of Gastroenterology2016,22,5:7
6A Lunar-based Soft X-ray Imager(LSXI)for the Earth's magnetosphere显示文摘We propose to use the Moon as a platform to obtain a global view of Earth's magnetosphere by a Lunar-based Soft X-ray Imager(LSXI).LSXI is a wide field-of-view Soft X-ray telescope,which can obtain X-ray images of Earth's magnetosphere based on the solar wind charge exchange(SWCX)X-ray emission.Global perspective is crucial to understand the overall interaction of the solar wind with magnetosphere.LSXI is capable of continuously monitoring the evolution of geospace conditions under the impact of the solar wind by simultaneous observation of the bow shock,magnetosheath,magnetopause and cusps for the first time.This proposal is answering the call for the Chinese Lunar Exploration Program Phase IV.Yihong GUO Chi WANG Fei WEI Tianran SUN Xizheng YU Songwu PENG Graziella BRANDUARDI-RAYMONT Steven SEMBAY 2021Science China Earth Sciences2021,64,7:5
7Treating children with inflammatory bowel disease: Current and new perspectives显示文摘Inflammatory bowel disease(IBD) is a chronic inflammatory condition of the gut characterised by alternating periods of remission and relapse. Whilst the mechanism underlying this disease is yet to be fully understood, old and newer generation treatments can only target selected pathways of this complex inflammatory process. This narrative review aims to provide an update on the most recent advances in treatment of paediatric IBD. A MEDLINE search was conducted using 'paediatric inflammatory bowel disease', 'paediatric Crohn's disease', 'paediatric ulcerative colitis', 'treatment', 'therapy', 'immunosuppressant', 'biologic', 'monitoring' and 'biomarkers' as key words. Clinical trials, systematic reviews, and meta-analyses published between 2014 and 2016 were selected. Studies referring to earlier periods were also considered in case the data was relevant to our scope. Major advances have been achieved in monitoring the individual metabolism, toxicity and response to relevant medications in IBD including thiopurines and biologics. New biologics acting on novel mechanisms such as selective interference with lymphocyte trafficking are emerging treatment options. Current research is investing in the development of reliable prognostic biomarkers, aiming to move towards personalised treatments targeted to individual patients.Graziella Guariso Marco Gasparetto 2017World Journal of Gastroenterology2017,23,30:5

9Serum chromogranin-A in hepatocellular carcinoma: Diagnostic utility and limits显示文摘AIM: The utility of serum alpha-fetoprotein (α-FP) for the detection of hepatocellular carcinoma (HCC) is questionable.High serum levels of chromogranin-A (CgA) have recently been reported in HCC. Impaired hepatic, renal, and heart functions influence circulating CgA. The aim of this study was to assess sensitivity and specificity of serum CgA as a marker of HCC in patients with liver cirrhosis (LC).METHODS: Serum CgA levels were measured by RIA in 339 patients of which 54 HCC, 132 LC, 45 chronic hepatitis (CH), 27 chronic heart failure (CHF), 36 chronic renal failure (CRF), 45 chronic inflammatory bowel disease (IBD)as disease controls and in 75 healthy controls. Patients with liver disease or IBD and concomitant renal and/or heart failure were excluded. Pearson correlation, nonparametric combination test and confidence interval analysis were used for statistical analysis.RESULTS: Serum CgA above normal values (100 ng/mL)were found in 83% of HCC patients, in 48% of LC patients,in 20% of CH patients, in 33% of IBD patients, in 92% of CRF patients, in 100% of CHF patients, and in none of the healthy controls. The mean CgA values in HCC (769±1 046), in LC (249±369), in CH (87±94), in CRF (1 390±1 401), in CHF (577±539), in IBD (146±287) were significantly higher than those in healthy controls (48±18).HCC patients had higher CgA values (P<0.01) than LC,CH, and IBD patients but did not differ from those with CRF or CHF. The 95% CI for the mean (250-1 289 ng/mL)in HCC patients was selected as a CgA range and the lower value of such range was assumed as cut-off.Sensitivity and specificity of CgA, calculated in relation to the cut-off in patients with cirrhosis and HCC, were respectively 61% (CI 48-73%) and 82% (CI 75-88%).Serum α-FP values were >200 ng/mL in 21% of the HCC patients and in none of the LC patients. No significant correlation was found between α-FP and CgA in patients with HCC and in patients with cirrhosis.CONCLUSION: When HCC is suspected and α-FP is normal or <200 ng/mL, CgA serum values represent a complementary diagnostic tool, unless kidney or heart failure is present.Aldo Spadaro Antonino Ajello Carmela Morace Agata Zirilli Graziella D'arrigo Carmelo Luigiano Francesco Martino Anna Bene Domenico Migliorato Santi Turiano Oscar Ferraù Maria Antonietta Freni 2005World Journal of Gastroenterology2005,11,13:4

12ALD growth of ultra-thin Co layers on the topological insulator Sb2Te3显示文摘Taking the full advantage of the conformal growth characterizing atomic layer deposition(ALD),the possibility to grow Co thin films,with thickness from several tens down to few nanometers on top of a granular topological insulator(TI)Sb2Tes film,exhibiting a quite high surface roughness(2-5 nm),was demonstrated.To study the Co growth on the Sb2Tes substrate,we performed simultaneous Co depositions also on sputtered Pt substrates for comparison.We conducted a thorough chemical-structural characterization of the Co/Sb2Tes and Co/Pt heterostructures,confirming for both cases,not only an excellent conformality,but also the structural continuity of the Co layers.X-ray diffraction(XRD)and high-resolution transmission electron microscope(HRTEM)analyses evidenced that Co on Sb2Te3 grows preferentially oriented along the[0oe]direction,following the underlying rhombohedric substrate.Differently,Co crystallizes in a cubic phase oriented along the[111]direction when deposited on Pt.This work shows that,in case of deposition of crystalline materials,the ALD surface selectivity and conformality can be extended to the definition of local epitaxy,where in-plane ordering of the crystal structure and mosaicity of the developed crystallized grains are dictated by the underlying substrate.Moreover,a highly sharp and chemically-pure Co/Sb2Tes interface was evidenced,which is promising for the application of this growth process for spintronics.Emanuele Longo Roberto Mantovan Raimondo Cecchini Michael D.Overbeek Massimo Longo Giovanna Trevisi Laura Lazzarini Graziella Tallarida Marco Fanciulli Charles H.Winter Claudia Wiemer 2020Nano Research2020,13,2:2
