2Tumor suppressor and hepatocellular carcinoma显示文摘A few signaling pathways are driving the growth of hepatocellular carcinoma.Each of these pathways possesses negative regulators.These enzymes,which normally suppress unchecked cell proliferation,are circumvented in the oncogenic process,either the overactivity of oncogenes is sufficient to annihilate the activity of tumor suppressors or tumor suppressors have been rendered ineffective.The loss of several key tumor suppressors has been described in hepatocellular carcinoma.Here,we systematically review the evidence implicating tumor suppressors in the development of hepatocellular carcinoma.Juliette Martin Jean-Franois Dufour 2008World Journal of Gastroenterology2008,14,11:10

6Medical management of metabolic and cardiovascular complications after liver transplantation显示文摘Liver transplantation represents the only curative option for patients with endstage liver disease,fulminant hepatitis and advanced hepatocellular carcinoma.Even though major advances in transplantation in the last decades have achieved excellent survival rates in the early post-transplantation period,long-term survival is hampered by the lack of improvement in survival in the late post transplantation period(over 5 years after transplantation).The main etiologies for late mortality are malignancies and cardiovascular complications.The latter are increasingly prevalent in liver transplant recipients due to the development or worsening of metabolic syndrome and all its components(arterial hypertension,dyslipidemia,obesity,renal injury,etc.).These comorbidities result from a combination of pre-liver transplant features,immunosuppressive agent side-effects,changes in metabolism and hemodynamics after liver transplantation and the adoption of a sedentary lifestyle.In this review we describe the most prevalent metabolic and cardiovascular complications present after liver transplantation,as well as proposing management strategies.Chiara Becchetti Melisa Dirchwolf Vanessa Banz Jean-Francois Dufour 2020World Journal of Gastroenterology2020,26,18:4

13Hepatocellular carcinoma in a non-cirrhotic patient with Wilson's disease显示文摘We report the exceptional case of hepatocellular carcinoma in a non-cirrhotic patient, whose Wilson's disease was diagnosed at the unusual age of 58 years. The liver histology revealed macrovesicular steatosis with fibrosis, but no cirrhosis. The disease was treated with D-penicillamine for 3 years until acute discomfort in the right upper quadrant led to detection of multifocal hepatocellular carcinoma, which was successfully resected. The histological examination confirmed the malignant nature of the 4 lesions, which were classified according to Edmondson and Steiner as poorly differentiated hepatocellular carcinoma grade 3. The non-tumoral parenchyma showed 80% steatosis with ballooned cells, lobular inflammation, septal fibrosis but no cirrhosis. Hepatocellular carcinoma is rare in Wilson's disease, especially in the absence of cirrhosis. The literature's 28 published cases are reviewed and the contributory role of copper in the hepatocarcinogenic process is discussed.Raphael Thattil Jean-Franois Dufour 2013World Journal of Gastroenterology2013,19,13:2
14The impact of the COVID-19 pandemic on the mental health of young people:A comparison between China and the United Kingdom显示文摘Purpose:As COVID-19 spreads globally and affects people's health,there are concerns that the pandemic and control policies may have psychological effects on young people(age from 17 to 35 years).This psychological impact might vary in different countries,and thus we compared the prevalence of self-reported psychological distress,loneliness and posttraumatic stress symptoms(PTSS)among young people in the United Kingdom(UK)and China at the beginning of the COVID-19 pandemic.Methods:Data of this study came from two sources.One source was the first wave of COVID-19 study in Understanding Society,a special wave of the UK household longitudinal study,which provided the high-quality,national-wide representative panel data.The sample comprised 1054 young people.The other source was an online survey on the mental health of 1003 young people from Shanghai,a highly developed area in China.The questionnaire included questions on the prevalence of common mental disorders(cut-off score≥4),loneliness and potential PTSS(cut-off≥33).Univariable analyses were conducted to test the differences in the self-reported prevalence of psychological distress and loneliness between the two groups.Multivariable logistic regression analyses were run to explore the predictors of psychological distress and loneliness among all the young people from England and Shanghai.Results:Among the samples with self-reported psychological distress,the UK sample accounted for 34.4%(n=1054)and the Chinese sample accounted for 14.1%(n=1003).The difference between the two groups was statistically significant(p<0.001).Additionally,57.1%of people in the UK and 46.7%in China reported that they sometimes or often felt lonely,of which the difference is statistically significant(p<0.001).Regression analysis of the entire samples showed that nationality,gender,psychotherapy and loneliness were significant predictors of 12-item General Health Questionnaire scores,while the variables of age and living alone were not.Significant predictors of self-reported loneliness were the nationality,gender,age,living alone and psychotherapy.In China,123(12.3%)young people,49 men(11.3%)and 74 women(13.0%),met the criteria of PTSS symptoms(cut-off scores≥33).These scores were only collected in China.Conclusion:This evidence suggests that mental health and loneliness reported by young people were lower in China than that in the UK during the studied period.More research is needed to understand these differences.If the differential negative psychological impacts are confirmed,country-specific measures of prevention and intervention should be adopted to improve the mental health of young people under the ongoing impact of the pandemic.Ming-Bo Liu Geraldine Dufour Zhuo-Er Sun Julieta Galante Chen-Qi Xing Jing-Ye Zhan Li-Li Wu 2021Chinese Journal of Traumatology2021,24,4:2
