| 2 | A silybin-phospholipids complex counteracts rat fatty liver degeneration and mitochondrial oxidative changes显示文摘AIM:To investigate the effectiveness of antioxidant compounds in modulating mitochondrial oxidative alterations and lipids accumulation in fatty hepatocytes.METHODS:Silybin-phospholipid complex containing vitamin E(Realsil) was daily administered by gavage(one pouch diluted in 3 mL of water and containing 15 mg vitamin E and 47 mg silybin complexed with phospholipids) to rats fed a choline-deprived(CD) or a high fat diet [20% fat,containing 71% total calories as fat,11% as carbohydrate,and 18% as protein,high fat diet(HFD)] for 30 d and 60 d,respectively.The control group was fed a normal semi-purified diet containing adequate levels of choline(35% total calories as fat,47% as carbohydrate,and 18% as protein).Circulating and hepatic redox active and nitrogen regulating molecules(thioredoxin,glutathione,glutathione peroxidase),NO metabolites(nitrosothiols,nitrotyrosine),lipid peroxides [malondialdehyde-thiobarbituric(MDA-TBA)],and pro-inflammatory keratins(K-18) were measured on days 0,7,14,30,and 60.Mitochondrial respiratory chain proteins and the extent of hepatic fatty infiltration were evaluated.RESULTS:Both diet regimens produced liver steatosis(50% and 25% of liver slices with CD and HFD,respectively) with no signs of necro-inflammation:fat infiltration ranged from large droplets at day 14 to disseminated and confluent vacuoles resulting in microvesicular steatosis at day 30(CD) and day 60(HFD).In plasma,thioredoxin and nitrosothiols were not significantly changed,while MDA-TBA,nitrotyrosine(from 6 ± 1 nmol/L to 14 ± 3 nmol/L day 30 CD,P < 0.001,and 12 ± 2 nmol/L day 60 HFD,P < 0.001),and K-18(from 198 ± 20 to 289 ± 21 U/L day 30 CD,P < 0.001,and 242 ± 23 U/L day 60 HFD,P < 0.001) levels increased significantly with ongoing steatosis.In the liver,glutathione was decreased(from 34.0 ± 1.3 to 25.3 ± 1.2 nmol/mg prot day 30 CD,P < 0.001,and 22.4 ± 2.4 nmol/mg prot day 60 HFD,P < 0.001),while thioredoxin and glutathione peroxidase were initially increased and then decreased.Nitrosothiols were constantly increased.MDA-TBA levels were five-fold increased from 9.1 ± 1.2 nmol/g to 75.6 ± 5.4 nmol/g on day 30,P < 0.001(CD) and doubled with HFD on day 60.Realsil administration significantly lowered the extent of fat infiltration,maintained liver glutathione levels during the first half period,and halved its decrease during the second half.Also,Realsil modulated thioredoxin changes and the production of NO derivatives and significantly lowered MDA-TBA levels both in liver(from 73.6 ± 5.4 to 57.2 ± 6.3 nmol/g day 30 CD,P < 0.01 and from 27.3 ± 2.1 nmol/g to 20.5 ± 2.2 nmol/g day 60 HFD,P < 0.01) and in plasma.Changes in mitochondrial respiratory complexes were also attenuated by Realsil in HFD rats with a major protective effect on Complex Ⅱ subunit CII-30.CONCLUSION:Realsil administration effectively contrasts hepatocyte fat deposition,NO derivatives formation,and mitochondrial alterations,allowing the liver to maintain a better glutathione and thioredoxin antioxidant activity. | Ignazio Grattagliano Catia V Diogo Maria Mastrodonato Ornella de Bari Michele Persichella David QH Wang Adriana Liquori Domenico Ferri Maria Rosaria Carratù Paulo J Oliveira Piero Portincasa | 2013 | World Journal of Gastroenterology2013，19，20： | 6 |
| 3 | Acute alcoholic hepatitis, end stage alcoholic liver disease and liver transplantation: An Italian position statement显示文摘Alcoholic liver disease encompasses a broad spectrum of diseases ranging from steatosis steatohepatitis,fibrosis,and cirrhosis to hepatocellular carcinoma.Forty-four per cent of all deaths from cirrhosis are attributed to alcohol.Alcoholic liver disease is the second most common diagnosis among patients undergoing liver transplantation(LT).The vast majority of transplant programmes(85%)require 6 mo of abstinence prior to transplantation;commonly referred to as the'6-mo rule'.Both in the case of progressive end-stage liver disease(ESLD)and in the case of severe acute alcoholic hepatitis(AAH),not responding to medical therapy,there is a lack of evidence to support a 6-mo sobriety period.It is necessary to identify other risk factors that could be associated with the resumption of alcohol drinking.The'Group of Italian Regions'suggests that:in a case of ESLD with model for end-stage liver disease<19 a 6-mo abstinence period is required;in a case of ESLD,a 3-mo sober period before LT may be more ideal than a 6-mo period,in selected patients;and in a case of severe AAH,not respond-ing to medical therapies(up to 70%of patients die within 6 mo),LT is mandatory,even without achieving abstinence.The multidisciplinary transplant team must include an addiction specialist/hepato-alcohologist.Patients have to participate in self-help groups. | Gianni Testino Patrizia Burra Ferruccio Bonino Francesco Piani Alessandro Sumberaz Roberto Peressutti Andrea Giannelli Castiglione Valentino Patussi Tiziana Fanucchi Ornella Ancarani Giovanna De Cerce Anna Teresa Iannini Giovanni Greco Antonio Mosti Marilena Durante Paola Babocci Mariano Quartini Davide Mioni Sarino Aricò Aniello Baselice Silvia Leone Fabiola Lozer Emanuele Scafato Paolo Borro | 2014 | World Journal of Gastroenterology2014，20，40： | 5 |
| 4 | Cognitive behavioural therapy for auditory hallucinations in schizophrenia:A review显示文摘AIM To provide an updated of recent findings about efficacy of cognitive-behavior therapy(CBT) in reduction of command hallucinations.METHODS Pub Med/MEDLINE,Cochrane Library,the Cumulative Index to Nursing and Allied Health Literature,PsycI NFO,Clinical Trial.gov searches were performed using the keywords 'hallucinations','behavioural therapy' and ' cognitive therapy' in order to identify relevant articles published during the years of 2011 to 2016.No language limits were used.Studies conducted within control group,reviews,editorials,were excluded.Data on efficacy,acceptability and tolerability were extracted by three authors independently.Disagreements were resolved in a consensus meeting or by another reviewer.RESULTS A total of eight articles were eligible for inclusion.Two are randomized clinical trials(RCTs) and six are observational studies.The two RCTs included showed a greater efficacy of CBT compared to standard care on auditory hallucinations(AHs).Nevertheless,they considered different CBT models,particularly Treatment of Resistant Command Hallucinations and Cognitive Therapy for Command Hallucinations.As regards non RCT-studies,all papers included showed reduction on frequency and severity of AHs and distress related to them.However,the lack of content details within non-RCTs studies decreased their comparability.In terms of predictive variables,our findings show that negative symptoms at baseline appeared to be the strongest predictor of the treatment efficacy.Indeed,negative symptoms showed a significant negative correlation on outcome.CONCLUSION Although more conclusive studies are still needed,we found some preliminary evidence for the efficacy of CBT in the treatment of command hallucinations. | Maria Pontillo Franco De Crescenzo Stefano Vicari Maria Laura Pucciarini Roberto Averna Ornella Santonastaso Marco Armando | 2016 | World Journal of Psychiatry2016，6，3： | 4 |

| 9 | Successful multidisciplinary clinical approach and molecular characterization by whole transcriptome sequencing of a cardiac myxofibrosarcoma: A case report显示文摘BACKGROUND Cardiac tumors are rare and complex entities.Surgery represents the cornerstone of therapy,while the role of adjuvant treatment remains unclear and,in case of relapse or metastatic disease,the prognosis is very poor.Lack of prospective,randomized clinical trials hinders the generation of high level evidence for the optimal diagnostic workup and multimodal treatment of cardiac sarcomas.Herein,we describe the multidisciplinary clinical management and molecular characterization of a rare case of cardiac myxofibrosarcoma in an elderly woman.CASE SUMMARY A 73-year-old woman presented signs and symptoms of acute left-sided heart failure.Imaging examination revealed a large,left atrial mass.With suspicion of a myxoma,she underwent surgery,and symptoms were promptly relieved.Histology showed a cardiac myxofibrosarcoma,a rare histotype of cardiac sarcoma.Eight months later,disease unfortunately relapsed,and after a multidisciplinary discussion,a chemotherapy with doxorubicin and then gemcitabine was started,achieving partial radiologic and complete metabolic response,which was maintained up to 2 years and is still present.This report is focused on the entire clinical path of our patient from diagnosis to follow-up,through surgery and strategies adopted at relapse.Moreover,due to their rarity,very little is known about the molecular landscape of myxofibrosarcomas.Thus,we also performed and described preliminary genome analysis of the tumor tissue to get further insight on mechanisms involved in tumor growth,and to possibly unveil new clinically actionable targets.CONCLUSION We report a case of cardiac myxofibrosarcoma that achieved a very good prognosis due to an integrated surgical,cardiac and oncologic treatment strategy. | Maristella Saponara Valentina Indio Carmine Pizzi Elena-Daniela Serban Milena Urbini Annalisa Astolfi Pasquale Paolisso Sofia Martin Suarez Margherita Nannini Davide Pacini Valentina Agostini Ornella Leone Valentina Ambrosini Giuseppe Tarantino Stefano Fanti Fabio Niro Francesco Buia Domenico Attinà Maria Abbondanza Pantaleo | 2019 | World Journal of Clinical Cases2019，7，19： | 2 |
| 10 | Modern surgical strategies for perianal Crohn's disease显示文摘One of the most challenging phenotypes of Crohn’s disease is perianal fistulizing disease(PFCD).It occurs in up to 50%of the patients who also have symptoms in other parts of the gastrointestinal tract,and in 5%of the cases it occurs as the first manifestation.It is associated with severe symptoms,such as pain,fecal incontinence,and a significant reduction in quality of life.The presence of perianal disease in conjunction with Crohn’s disease portends a significantly worse disease course.These patients require close monitoring to identify those at risk of worsening disease,suboptimal biological drug levels,and signs of developing neoplasm.The last 2 decades have seen significant advancements in the management of PFCD.More recently,newer biologics,cell-based therapies,and novel surgical techniques have been introduced in the hope of improved outcomes.However,in refractory cases,many patients face the decision of having a stoma made and/or a proctectomy performed.In this review,we describe modern surgical management and the most recent advances in the management of complex PFCD,which will likely impact clinical practice. | Gilmara Pandolfo Zabot Ornella Cassol Rogerio Saad-Hossne Willem Bemelman | 2020 | World Journal of Gastroenterology2020，26，42： | 2 |
