2challenges of advanced hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is an aggressive malignancy,resulting as the third cause of death by cancer each year. The management of patients with HCC is complex,as both the tumour stage and any underlying liver disease must be considered conjointly. Although surveillance by imaging,clinical and biochemical parameters is routinely performed,a lot of patients suffering from cirrhosis have an advanced stage HCC at the first diagnosis. Advanced stage HCC includes heterogeneous groups of patients with different clinical condition and radiological features and sorafenib is the only approved treatment according to Barcelona Clinic Liver Cancer. Since the introduction of sorafenib in clinical practice,several phase Ⅲ clinical trials have failed to demonstrate any superiority over sorafenib in the frontline setting. Locoregional therapies have also been tested as first line treatment,but their role in advanced HCC is still matter of debate. No single agent or combination therapies have been shown to impact outcomes after sorafenib failure. Therefore this review will focus on the range of experimental therapeutics for patients with advanced HCC and highlights the successes and failures of these treatments as well as areas for future development. Specifics such as dose limiting toxicity and safety profile in patients with liver dysfunction related to the underlying chronic liver disease should be considered when developing therapies in HCC. Finally,robust validated and reproducible surrogate end-points as well as predictive biomarkers should be defined in future randomized trials.Stefano Colagrande Andrea L Inghilesi Sami Aburas Gian G Taliani Cosimo Nardi Fabio Marra 2016World Journal of Gastroenterology2016,22,34:19
3Holocene climate change in the Central Tibetan Plateau inferred by lacustrine sediment geochemical records显示文摘Multi-proxies of lacustrine sediments, such as total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC), total nitrogen (TN), total sulfur (TS), hydrogen index (HI), oxygen index (OI) and stable carbon isotopic composition of organic matter (δ 13Corg), were analyzed using a 7.3 m core from Zigê Tangco. The source of the organic matter in the sediment was mainly from autochthonous phytoplankton, therefore the significances of proxies can be interpreted as that high TOC, TOC/TS, HI and δ13Corg values, low TC, TIC values corresponded to warm and wet climatic condition, and vice versa. The process of climatic development in the Zigê Tangco region was hence recovered. During the early and Mid-Holocene, the climate was warm and wet and intensive cold events occurred during the periods of 8600 to 8400 cal a BP and 7400 to 7000 cal a BP. In the second half of Holocene, the climate became cold and dry gradually. The palaeoclimatic process during Holocene in Zigê Tangco region matched well with that in Co Ngoin region which is ca 40 km to the south-east. Therefore this palaeoclimatic process represents the Holocene climatic feature in the Central Tibetan Plateau which has the same pattern in the Northern Tibetan Plateau, but the time and duration of some climatic events might be different. We can conclude that in Holocene solar insolation controlled the climatic pattern on the central Tibetan Plateau.Andreas LüCKE Bernd WüNNEMANN 2007Science China Earth Sciences2007,50,10:16
4Ten years of sorafenib in hepatocellular carcinoma: Are there any predictive and/or prognostic markers?显示文摘Sorafenib has been considered the standard of care for patients with advanced unresectable hepatocellular carcinoma(HCC) since 2007 and numerous studieshave investigated the role of markers involved in the angiogenesis process at both the expression and genetic level and clinical aspect. What results have ten years of research produced? Several clinical and biological markers are associated with prognosis. The most interesting clinical parameters are adverse events, Barcelona Clinic Liver Cancer stage, and macroscopic vascular invasion, while several single nucleotide polymorphisms and plasma angiopoietin-2 levels represent the most promising biological biomarkers. A recent pooled analysis of two phase III randomized trials showed that the neutrophil-to-lymphocyte ratio, etiology and extra-hepatic spread are predictive factors of response to sorafenib, but did not identify any predictive biological markers. After 10 years of research into sorafenib there are still no validated prognostic or predictive factors of response to the drug in HCC. The aim of the present review was to summarize 10 years of research into sorafenib, looking in particular at the potential of associated clinical and biological markers to predict its efficacy in patients with advanced HCC.Giorgia Marisi Alessandro Cucchetti Paola Ulivi Matteo Canale Giuseppe Cabibbo Leonardo Solaini Francesco G Foschi Serena De Matteis Giorgio Ercolani Martina Valgiusti Giovanni L Frassineti Mario Scartozzi Andrea Casadei Gardini 2018World Journal of Gastroenterology2018,24,36:14
5Helicobacter pylori and autoimmune disease:Cause or bystander显示文摘Helicobacter pylori(H.pylori)is the main cause of chronic gastritis and a major risk factor for gastric cancer.This pathogen has also been considered a potential trigger of gastric autoimmunity,and in particular of autoimmune gastritis.However,a considerable number of reports have attempted to link H.pylori infection with the development of extra-gastrointestinal autoimmune disorders,affecting organs not immediately relevant to the stomach.This review discusses the current evidence in support or against the role of H.pylori as a potential trigger of autoimmune rheumatic and skin diseases,as well as organ specific autoimmune diseases.We discuss epidemiological,serological,immunological and experimental evidence associating this pathogen with autoimmune diseases.Although over one hundred autoimmune diseases have been investigated in relation to H.pylori,we discuss a select number of papers with a larger literature base,and include Sj grens syndrome,rheumatoid arthritis,systemic lupus erythematosus,vasculitides,autoimmune skin conditions,idiopathic thrombocytopenic purpura,autoimmune thyroid disease,multiple sclerosis,neuromyelitis optica and autoimmune liver diseases.Specific mention is given to those studies reporting an association of anti-H.pylori antibodies with the presence of autoimmune disease-specific clinical parameters,as well as those failing to find such associations.We also provide helpful hints for future research.Daniel S Smyk Andreas L Koutsoumpas Maria G Myt-ilinaiou Eirini I Rigopoulou Lazaros I Sakkas Dimitrios P Bogdanos 2014World Journal of Gastroenterology2014,20,3:12
6An integrated approach for increasing breeding efficiency in apple and peach in Europe显示文摘Despite the availability of whole genome sequences of apple and peach,there has been a considerable gap between genomics and breeding.To bridge the gap,the European Union funded the FruitBreedomics project(March 2011 to August 2015)involving 28 research institutes and private companies.Three complementary approaches were pursued:(i)tool and software development,(ii)deciphering genetic control of main horticultural traits taking into account allelic diversity and(iii)developing plant materials,tools and methodologies for breeders.Decisive breakthroughs were made including the making available of ready-to-go DNA diagnostic tests for Marker Assisted Breeding,development of new,dense SNP arrays in apple and peach,new phenotypic methods for some complex traits,software for gene/QTL discovery on breeding germplasm via Pedigree Based Analysis(PBA).This resulted in the discovery of highly predictive molecular markers for traits of horticultural interest via PBA and via Genome Wide Association Studies(GWAS)on several European genebank collections.FruitBreedomics also developed pre-breeding plant materials in which multiple sources of resistance were pyramided and software that can support breeders in their selection activities.Through FruitBreedomics,significant progresses were made in the field of apple and peach breeding,genetics,genomics and bioinformatics of which advantage will be made by breeders,germplasm curators and scientists.A major part of the data collected during the project has been stored in the FruitBreedomics database and has been made available to the public.This review covers the scientific discoveries made in this major endeavour,and perspective in the apple and peach breeding and genomics in Europe and beyond.Francois Laurens Maria JoséAranzana Pere Arus Daniele Bassi Marco Bink Joan Bonany Andrea Caprera Luca Corelli-Grappadelli Evelyne Costes Charles-Eric Durel Jehan-Baptiste Mauroux Hélène Muranty Nelson Nazzicari Thierry Pascal Andrea Patocchi Andreas Peil Bénédicte Quilot-Turion Laura Rossini Alessandra Stella Michela Troggio Riccardo Velasco Eric van de Weg 2018Horticulture Research2018,5,1:10

8Matched-pair analysis of postoperative morbidity and mortality for pancreaticogastrostomy and pancreaticojejunostomy using mattress sutures in soft pancreatic tissue remnants显示文摘BACKGROUND:After pancreaticoduodenectomy,the incidence of postoperative pancreatic fistula remains high,especially in patients with 'soft' pancreatic tissue remnants.No 'gold standard' surgical technique for pancreaticoenteric anastomosis has been established.This study aimed to compare the postoperative morbidity and mortality of pancreaticogastrostomy and pancreaticojejunostomy for 'soft' pancreatic tissue remnants using modified mattress sutures.METHODS:Seventy-five patients who had undergone pancreaticogastrostomy and 75 who had undergone pancreaticojejunostomy after pancreaticoduodenectomy between 2002 and 2008 were retrospectively compared using matched-pair analysis.A modified mattress suture technique was used for the pancreaticoenteric anastomosis.Patients with an underlying 'hard' pancreatic tissue remnant,as in chronic pancreatitis,were excluded.Both groups were homogeneous for age,gender,and underlying disease.Postoperative morbidity,mortality,and preoperative and operative data were analyzed.RESULTS:There were no significant differences between the groups for the incidence of postoperative pancreatic fistula (10.7% in both).Postoperative morbidity and mortality,median operation time,median length of hospital stay,intraoperative blood loss,and the amount of intraoperatively transfused erythrocyte concentrates also did not significantly differ between the groups.Patient age >65 years (P=0.017),operation time >350minutes (P=0.001),and intraoperative transfusion of erythrocyte concentrates (P=0.038) were identified as risk factors for postoperative morbidity.CONCLUSIONS:Our results showed no significant differences between the groups in the pancreaticogastrostomy and pancreaticojejunostomy anastomosis techniques using mattress sutures for 'soft' pancreatic tissue remnants.In our experience,the mattress sutures are safe and simple to use,and pancreaticogastrostomy in particular is feasible and easy to learn,with good endoscopic accessibility to the anastomosis region.However,the location of the anastomosis and the surgical technique need to be individually evaluated to further reduce the incidence of postoperative pancreatic fistula.Fritz Klein Marcus Bahra Matthias Glanemann Wladimir Faber Peter Warnick Andreas Andreou Safak Gül Dietmar Jacob 2012Hepatobiliary & Pancreatic Diseases International2012,11,1:9

10Subclinical carotid atherosclerosis predicts all-cause mortality and cardiovascular events in obese patients with negative exercise echocardiography显示文摘BACKGROUND Obesity is a major health problem due to its high prevalence. The relationship between obesity and cardiovascular disease is unclear. Some studies agree that certain conditions associated with obesity, such as physical inactivity or cardiovascular risk factors, are responsible for cardiovascular risk excess among obese people. Carotid intima-media thickness and carotid plaques(CP) have been associated with cardiovascular adverse events in healthy populations, and recent data suggest a higher prevalence of subclinical carotid atherosclerosis in obese and metabolically unhealthy patients. However, there are no studies correlating subclinical atherosclerosis and adverse events(AE) in obese subjects.AIM To determine the association between carotid disease and AE in obese patients with negative exercise echocardiography(EE).METHODS From January 1, 2006 to December 31, 2010, 2000 consecutive patients with a suspicion of coronary artery disease were submitted for EE and carotid ultrasonography. Exclusion criteria included previous vascular disease, left ventricular ejection fraction < 50%, positive EE, significant valvular heart disease and inferior to submaximal EE. An AE was defined as all-cause mortality,myocardial infarction and cerebrovascular accident. Subclinical atherosclerosis was defined as CP presence according to Manheim and the American Society of Echocardiography Consensus.RESULTS Of the 652 patients who fulfilled the inclusion criteria, 226(34.7%) had body mass indexes ≥ 30 kg/m2, and 76 of them(33.6%) had CP. During a mean follow-up time of 8.2(2.1) years, 27 AE were found(11.9%). Mean event-free survival at 1, 5 and 10 years was 99.1%(0.6), 95.1%(1.4) and 86.5%(2.7), respectively. In univariate analysis, CP predicted AE [hazard ratio(HR) 2.52, 95% confidence interval(CI) 1.17-5.46; P = 0.019]. In multivariable analysis, the presence of CP remained a predictor of AE(HR 2.26, 95%CI 1.04-4.95, P = 0.041). Other predictors identified were glomerular filtration rate(HR 0.98, 95%CI 0.96-0.99; P= 0.023), peak metabolic equivalents(HR 0.83, 95%CI 0.70–0.99, P = 0.034) and moderate mitral regurgitation(HR 5.02, 95%CI 1.42–17.75, P = 0.012).CONCLUSION Subclinical atherosclerosis defined by CP predicts AE in obese patients with negative EE. These patients could benefit from aggressive prevention measures.Rafael Vidal-Perez Raúl Franco-Gutiérrez Alberto J Pérez-Pérez Virginia Franco-Gutiérrez Alberto Gascón-Vázquez Andrea López-López Ana María Testa-Fernández Carlos González-Juanatey 2019World Journal of Cardiology2019,11,1:7
11Prospective evaluation of small bowel preparation with bisacodyl and sodium phosphate for capsule endoscopy显示文摘AIM: To determine the effect of Prepacol?, a com- bination of sodium phosphate and bisacodyl, on transit and quality of capsule endoscopy (CE). METHODS: Fivety two consecutive patients were included in this prospective study. CE was performed following a 12 h fasting period. Twenty six patients were randomized for additional preparation with Prepacol?. The quality of CE was assessed separately for the proximal and the distal small bowel by 3 experienced endoscopists on the basis of a graduation which was initially developed with 20 previous CE. RESULTS: Preparation with Prepacol? accelerated small bowel transit time (262 ± 55 min vs 287 ± 97 min), but had no effect on the quality of CE. Visibility was significantly reduced in the distal compared to the proximal small bowel. CONCLUSION: The significantly reduced visibility of CE in the distal small bowel allocates the need for a good preparation. Since Prepacol? has no beneficial effect on CE the modality of preparation and the ideal time of application remains unclear. Further standardized examinations are necessary to identify sufficient preparation procedures and to determine the impact of the volume of the preparation solution.Andreas Franke Frank Hummel Phillip Knebel Christoph Antoni Ulrich Bcker Manfred V Singer Matthias Lhr 2008World Journal of Gastroenterology2008,14,13:5
12Effect of aerobic and anaerobic exercises on glycemic control in type 1 diabetic youths显示文摘AIM:To evaluate the long-term effect of aerobic and/or anaerobic exercise on glycemic control in youths with type 1 diabetes.METHODS:Literature review was performed in spring and summer 2014 using Pub Med/MEDLINE,Google Scholar,Scopus,and Science Direct with the following terms:aerobic,anaerobic,high-intensity,resistance,exercise/training,combined with glycemic/metabolic control,glycated haemoglobin A1c(Hb A1c) and type 1diabetes.Only peer-reviewed articles in English were included published in the last 15 years.It was selected from 1999 to 2014.Glycemic control was measured with Hb A1 c.Studies with an intervention lasting at least 12 wk were included if the Hb A1 c was measured before and after the intervention.RESULTS:A total of nine articles were found,and they were published between the years of 2002-2011.The sample size was 401 diabetic youths(166 males and 235 females) with an age range of 10-19 years except one study,in which the age range was 13-30 years.Study participants were from Australia,Tunisia,Lithuania,Taiwan,Turkey,Brazilia,Belgium,Egypt and France.Four studies were aerobic-based,four were combined aerobic and anaerobic programs,and one compared aerobic exercise to anaerobic one.Available studies had insufficient evidence that any type of exercise or combined training would clearly improve the glycemic control in type 1 diabetic youth.Only three(two aerobic-based and one combined) studies could provide a significant positive change in glycemic control.CONCLUSION:The regular physical exercise has several other valuable physiological and health benefits that justify the inclusion of exercise in pediatric diabetes treatment and care.Andrea Lukács László Barkai 2015World Journal of Diabetes2015,6,3:5

16High prevalence of vitamin A deficiency in Crohn's disease patients according to serum retinol levels and the relative dose-response test显示文摘AIM:To assess the vitamin A status of patients with Crohn's disease(CD) by evaluating serum retinol levels and the relative dose response(RDR) test(liver retinol stores).METHODS:Vitamin A nutritional status was measured by serum retinol obtained by high performance liquid chromatography and the RDR test for evaluation of the hepatic stores.Body composition was performed by densitometry by dual-energy X-ray absorptiometry.Vitamin A dietary intake was assessed from a semiquantitative food frequency questionnaire.RESULTS:This study included 38 CD patients and 33 controls.Low serum retinol concentrations were detected in 29% of CD patients vs 15% in controls(P < 0.005).The RDR test was positive in 37% of CD patients vs 12% in controls,which indicated inadequate hepatic vitamin A stores(P < 0.005).Individuals with hypovitaminosis A had lower BMI and body fat compared with those without this deficiency.There was no association between vitamin A deficiency and its dietary intake,ileal location,presence of disease activity and prior bowel resections.CONCLUSION:Patients with CD have higher prevalence of vitamin A deficiency,as assessed by two independent methods.Márcia Soares-Mota Tianny A Silva Luanda M Gomes Marco AS Pinto Laura MC Mendon?a Maria Lúcia F Farias Tiago Nunes Andrea Ramalho Cyrla Zaltman 2015World Journal of Gastroenterology2015,21,5:4
17Radiological response and inflammation scores predict tumour recurrence in patients treated with transarterial chemoembolization before liver transplantation显示文摘AIM To investigate the prognostic value of the radiological response after transarterial chemoembolization(TACE)and inflammatory markers in patients affected by hepatocellular carcinoma(HCC)awaiting liver transplantation(LT).METHODS We retrospectively evaluated the preoperative pre dictors of HCC recurrence in 70 patients treated with conventional(n=16)or doxorubicin-eluting bead TACE(n=54)before LT.The patient and tumour characteristics,including the static and dynamic alpha-fetoprotein,neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio( LR)measurements,were recorded.Treatment response was classified according to the modified Response Evaluation Criteria in Solid Tumours(m RECIST)and the European Association for the Study of the Liver(EASL)criteria as complete response(CR),partial response( R),stable disease o progressive disease.After examination of the explanted livers,histological necrosis was classified as complete(100%of the cumulative tumour area),partia(50%-99%)or minimal(<50%)and was correlated with the preoperative radiological findings.RESULTS According to the pre-TACE radiological evaluation,22/70(31.4%)and 12/70(17.1%)patients were beyond Milan and University of San Francisco(UCSF)criteria,respectively.After TACE procedures,the objective response(CR+ R)rates were 71.4%and 70.0%according to m RECIST and EASL criteria,respectively.The agreement between the two guidelines in defining the radiological response was rated as very good both for the overall and target lesion response(weighted k-value:0.98 and 0.93,respectively).Complete and partial histological necrosis were achieved in 14/70(20.0%)and 28/70(40.0%)patients,respectively.Using histopathology as the reference standard,m RECIST criteria correctly classified necrosis in 72.9%(51/70)of patients and EASL criteria in 68.6%(48/70)of cases.The m RECIST non-response to TACE[Exp(b)=9.2, =0.012],exceeding UCSF criteria before TACE[Exp(b)=4.7, =0.033]and a preoperative LR>150[Exp(b)=5.9, =0.046]were independent predictors of tumour recurrence.CONCLUSION The radiological response and inflammatory markers are predictive of tumour recurrence and allow the proper selection of TACE-treated candidates for LT.Daniele Nicolini Andrea Agostini Roberto Montalti Federico Mocchegiani Cinzia Mincarelli Alessandra Mandolesi Nicola L Robertson Roberto Candelari Andrea Giovagnoni Marco Vivarelli 2017World Journal of Gastroenterology2017,23,20:4

19Genomic prediction of fruit texture and training population optimization towards the application of genomic selection in apple显示文摘Texture is a complex trait and a major component of fruit quality in apple.While the major effect of MdPG1,a gene controlling firmness,has already been exploited in elite cultivars,the genetic basis of crispness remains poorly understood.To further improve fruit texture,harnessing loci with minor effects via genomic selection is therefore necessary.In this study,we measured acoustic and mechanical features in 537 genotypes to dissect the firmness and crispness components of fruit texture.Predictions of across-year phenotypic values for these components were calculated using a model calibrated with 8,294 SNP markers.The best prediction accuracies following cross-validations within the training set of 259 genotypes were obtained for the acoustic linear distance(0.64).Predictions for biparental families using the entire training set varied from low to high accuracy,depending on the family considered.While adding siblings or half-siblings into the training set did not clearly improve predictions,we performed an optimization of the training set size and composition for each validation set.This allowed us to increase prediction accuracies by 0.17 on average,with a maximal accuracy of 0.81 when predicting firmness in the‘Gala’בPink Lady’family.Our results therefore identified key genetic parameters to consider when deploying genomic selection for texture in apple.In particular,we advise to rely on a large training population,with high phenotypic variability from which a‘tailored training population’can be extracted using a priori information on genetic relatedness,in order to predict a specific target population.Morgane Roth Hélène Muranty Mario Di Guardo Walter Guerra Andrea Patocchi Fabrizio Costa 2020Horticulture Research2020,7,1:4
20Detection and characterization of murine colitis and carcinogenesis by molecularly targeted contrast-enhanced ultrasound显示文摘AIM To study mucosal addressin cellular adhesion molecule-1(MAd CAM-1) and vascular endothelial growth factor(VEGF)-targeted contrast enhanced ultrasound(CEUS) for the assessment of murine colitis and carcinogenesis. METHODS C57BL/6 mice were challenged with 3% dextran sodium-sulfate(DSS) for three, six or nine days to study the development of acute colitis. Ultrasound was performed with and without the addition of unspecific contrast agents. MAd CAM-1-targeted contrast agent was used to detect and quantify MAd CAM-1 expression. Inflammatory driven colorectal azoxymethane(AOM)/DSS-induced carcinogenesis was examined on day 42 and 84 using VEGF-targeted contrast agent. Highly specific tissue echogenicity was quantified using specialized software. Sonographic findings were correlated to tissue staining, western blot analysis and immunohistochemistry to quantify the degree of inflammation and stage of carcinogenesis. RESULTS Native ultrasound detected increased general bowel wall thickening that correlated with more progressed and more severe DSS-colitis(healthy mice: 0.3 mm ± 0.03 vs six days DSS: 0.5 mm ± 0.2 vs nine days DSS: 0.6 mm ± 0.2, P < 0.05). Moreover, these sonographic findings correlated well with clinical parameters such as weight loss(r2 = 0.74) and histological damage(r2 = 0.86)(P < 0.01). In acute DSS-induced murine colitis, CEUS targeted against MAd CAM-1 detected and differentiated stages of mild, moderate and severe colitis via calculation of mean pixel contrast intensity in decibel(9.6 d B ± 1.6 vs 12.9 d B ± 1.4 vs 18 d B ± 3.33, P < 0.05). Employing the AOM/DSSinduced carcinogenesis model, tumor development was monitored by CEUS targeted against VEGF and detected a significantly increased echogenicity in tumors as compared to adjacent healthy mucosa(healthy mucosa, 1.6 d B ± 1.4 vs 42 d, 18.2 d B ± 3.3 vs 84 d, 18.6 d B ± 4.9, P < 0.01). Tissue echogenicity strongly correlated with histological analysis and immunohistochemistry findings(VEGF-positive cells in 10 high power fields of healthy mucosa: 1 ± 1.2 vs 42 d after DSS start: 2.4 ± 1.6 vs 84 d after DSS start: 3.5 ± 1.3, P < 0.01). CONCLUSION Molecularly targeted CEUS is a highly specific and noninvasive imaging modality, which characterizes murine intestinal inflammation and carcinogenesis in vivo.Markus Brückner Jan Heidemann Tobias M Nowacki Friederike Cordes Jorg Stypmann Philipp Lenz Faekah Gohar Andreas Lügering Dominik Bettenworth 2017World Journal of Gastroenterology2017,23,16:4
