| 1 | Effects of resveratrol in experimental and clinical non-alcoholic fatty liver disease显示文摘The prevalence of obesity and related conditions like non-alcoholic fatty liver disease(NAFLD) is increasing worldwide and therapeutic options are limited.Alternative treatment options are therefore intensively sought after.An interesting candidate is the natural polyphenol resveratrol(RSV) that activates adenosinmonophosphate-activated protein kinase(AMPK) and silent information regulation-2 homolog 1(SIRT1).In addition,RSV has known anti-oxidant and anti-inflammatory effects.Here,we review the current evidence for RSVmediated effects on NAFLD and address the different aspects of NAFLD and non-alcoholic steatohepatitis(NASH) pathogenesis with respect to free fatty acid(FFA) flux from adipose tissue,hepatic de novo lipogenesis,inadequate FFA β-oxidation and additional intra- and extrahepatic inflammatory and oxidant hits.We review the in vivo evidence from animal studies and clinical trials.The abundance of animal studies reports a decrease in hepatic triglyceride accumulation,liver weight and a general improvement in histological fatty liver changes,along with a reduction in circulating insulin,glucose and lipid levels.Some studies document AMPK or SIRT1 activation,and modulation of relevant markers of hepatic lipogenesis,inflammation and oxidation status.However,AMPK/SIRT1-independent actions are also likely.Clinical trials are scarce and have primarily been performed with a focus on overweight/obese participants without a focus on NAFLD/NASH and histological liver changes.Future clinical studies with appropriate design are needed to clarify the true impact of RSV treatment in NAFLD/NASH patients. | Sara Heebll Karen Louise Thomsen Steen B Pedersen Hendrik Vilstrup Jacob George Henning Grnbk | 2014 | World Journal of Hepatology2014，6，4： | 11 |
| 2 | Bariatric surgery in patients with non-alcoholic fatty liver disease-from pathophysiology to clinical effects显示文摘Non-alcoholic fatty liver disease(NAFLD) is increasingly recognized as a significant liver disease,and it covers the disease spectrum from simple steatosis with a risk of development of non-alcoholic steatohepatitis(NASH) to fibrosis,subsequent cirrhosis,end-stage liver failure,and liver cancer with a potential need for liver transplantation.NAFLD and NASH are closely related to obesity,metabolic syndrome,and type 2 diabetes(T2 D).The role of gut hormones,especially glucagon-like peptide 1(GLP-1),is important in NAFLD.Bariatric surgery has the potential for inducing great weight loss and may improve the symptoms of metabolic syndrome and T2 D.Recent data demonstrated significant effects of bariatric surgery on GLP-1 and other gut hormones and important lipid metabolic and inflammatory abnormalities in the pathophysiology of NAFLD.Therefore,bariatric surgery may reverse the pathological liver changes in NAFLD and NASH patients.In the present review,we describe NAFLD and NASH pathophysiology and the primary effects of bariatric surgery on metabolic pathways.We performed a systematic review of the beneficial and harmful effects and focused on changes in liver disease severity in NAFLD and NASH patients.The specific focus was liver histopathology as assessed by the invasive liver biopsy.Additionally,we reviewed several non-invasive methods used for the assessment of liver disease severity following bariatric surgery. | Tea L Laursen Christoffer A Hagemann Chunshan Wei Konstantin Kazankov Karen L Thomsen Filip K Knop Henning Grønbæk | 2019 | World Journal of Hepatology2019，11，2： | 11 |
| 3 | Molecular mechanism and functional consequences of lansoprazole-mediated heme oxygenase-1 induction显示文摘AIM:To investigate the molecular mechanism and functional consequences of heme oxygenase-1(HO-1) activation by lansoprazole in endothelial cells and macrophages. METHODS:Expression of HO-1 mRNA was analyzed by Northern blotting.Western blotting was used to determine the HO-1 and ferritin protein levels. NADPH-dependent reactive oxygen species(ROS) formation was measured with lucigenin-enhanced chemiluminescence.HO-1 promoter activity in mouse fibroblasts,stably transfected with a 15-kb HO-1 gene that drives expression of the reporter gene luciferase, was assessed using in vivo bioluminescence imaging. RESULTS:Lansoprazole increased HO-1 mRNA levels in endothelial cells and HO-1 protein levelsin macrophages.In addition,lansoprazole-induced ferritin protein levels in both cell systems.Moreover, induction of the antioxidant proteins HO-1 and ferritin by lansoprazole was followed by a decrease in NADPH- mediated ROS formation.The radical scavenging properties of lansoprazole were diminished in the presence of the HO inhibitor,chromium mesoporphyrin IX.Induction of HO-1 gene expression by lansoprazole was not related to oxidative stress or to the activation of the mitogen-activated protein kinase pathway. However,the phosphatidylinositol 3-kinase inhibitor LY294002 showed a concentration-dependent inhibition of HO-1 mRNA and promoter activity. CONCLUSION:Activation of HO-1 and ferritin may account for the gastric protection of lansoprazole and is dependent on a pathway blocked by LY294002. | Stephanie Schulz-Geske Kati Erdmann Ronald J Wong David K Stevenson Henning Schrder Nina Grosser | 2009 | World Journal of Gastroenterology2009，15，35： | 7 |
| 4 | Trefoil factors in inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD),which comprises ulcerative colitis and Crohn’s disease,is characterized by inflammation of the gastrointestinal tract.The trefoil factors 1,2,and 3(TFF1-3)are a family of peptides that play important roles in the protection and repair of epithelial surfaces,including the gastrointestinal tract.TFFs may be involved in IBD pathogenesis and are a potential treatment option.In the present review,we describe the TFF family and their potential role in IBD by summarizing the current knowledge of their expression,possible function and pharmacological role in IBD. | Luise Aamann Else Marie Vestergaard Henning Grφnbk | 2014 | World Journal of Gastroenterology2014，20，12： | 6 |
| 5 | New tight junction protein 2 variant causing progressive familial intrahepatic cholestasis type 4 in adults: A case report显示文摘BACKGROUND Progressive familial intrahepatic cholestasis(PFIC)encompasses a group of autosomal recessive disorders with high morbidity and mortality.Variants in the gene encoding tight junction protein-2(TJP2)have been linked to PFIC type 4(PFIC4),which predominantly presents in childhood.However,there are only limited data from adults with TJP2-related PFIC4.We report a family with an autosomal recessive disorder with a novel variant in the TJP2 gene in adults with very variable expression of PFIC4.CASE SUMMARY The index patient presented at 19 years old with liver cirrhosis and variceal bleeding and was treated with endoscopic banding and beta-blockers.In 2018,he developed primary liver cancer that was treated with radiofrequency ablation followed by liver transplantation in 2019.Genetic testing revealed a novel homozygous TJP2 variant causing PFIC4(TJP2([NM_004817.3]:c.[3334C>T];[3334C>T])).The consanguineous family consists of the father and mother(both heterozygous)and their 12 children,of which five carry the variant in a homozygous state;however,these five siblings have highly variable expression of PFIC4.Two homozygous brothers had cirrhosis and portal hypertension at diagnosis at the ages of 19 and 36.Two other homozygous brothers,age 23 and 19,and the homozygous sister,age 21,have elevated liver enzymes but presently no cirrhosis,which may suggest an age-dependent penetrance.In addition,five sisters had severe and mild intrahepatic cholestasis of pregnancy and carry the TJP2 variant in a homozygous and heterozygous state,respectively.CONCLUSION This novel TJP2 variant is associated with PFIC4 causing severe liver disease with cirrhosis and primary liver cancer in adolescents/adults. | Chun-Shan Wei Naja Becher Jenny Blechingberg Friis Peter Ott Ida Vogel Henning Grønbæk | 2020 | World Journal of Gastroenterology2020，26，5： | 6 |
| 6 | Treatment of Budd-Chiari syndrome with a focus on transjugular intrahepatic portosystemic shunt显示文摘AIM:To evaluate long-term complications and survival in patients with Budd-Chiari syndrome (BCS) referred to a Danish transjugular intrahepatic portosystemic shunt (TIPS) centre.METHODS:Twenty-one consecutive patients from 1997-2008 were retrospectively included [15 women and 6 men,median age 40 years (range 17-66 years)].Eighteen Danish patients came from the 1.8 million catchment population of Aarhus University Hospital and three patients were referred from Scandinavian hospitals.Management consisted of tests for underlying haematological,endocrinological,or hypercoagulative disorders parallel to initiation of specific treatment of BCS.RESULTS:BCS was mainly caused by thrombophilic (33%) or myeloproliferative (19%) disorders.Fortythree percents had symptoms for less than one week with ascites as the most prevalent finding.Fourteen (67%) were treated with TIPS and 7 (33%) were manageable with treatment of the underlying condition and diuretics.The median follow-up time for the TIPS-treated patients was 50 mo (range 15-117 mo),and none required subsequent liver transplantation.Ascites control was achieved in all TIPS patients with a marked reduction in the dose of diuretics.A total of 14 TIPS revisions were needed,mostly of uncovered stents.Two died during follow-up:One non-TIPS patient worsened after 6 mo and died in relation to transplantation,and one TIPS patient died 4 years after the TIPS-procedure,unrelated to BCS.CONCLUSION:In our BCS cohort TIPS-treated patients have near-complete survival,reduced need for diuretics and compared to historical data a reduced need for liver transplantation. | Anders Bay Neumann Stine Degn Andersen Dennis Tφnner Nielsen Peter Holland-Fischer Hendrik Vilstrup Henning Grφnbk | 2013 | World Journal of Hepatology2013，5，1： | 5 |
| 7 | Body composition changes after transjugular intrahepatic portosystemic shunt in patients with cirrhosis显示文摘AIM:To investigate the effect of transjugular intra-hepatic porto-systemic shunt (TIPS) on malnutrition in portal hypertensive cirrhotic patients.METHODS: Twenty-one patients with liver cirrhosis and clinical indications for TIPS insertion were investigated before and 1, 4, 12, 52 wk after TIPS. For each patient we assayed body composition parameters [dry lean mass, fat mass, total body water (TBW)], routine liver and kidney function tests, and free fatty acids (FFA). Glucose and insulin were measured for the calculation of the homeostasis model assessment insulin resistance (HOMA-IR); liver function was measured by the galactose elimination capacity (GEC); the severity of liver disease was graded by model for end-stage liver disease (MELD).RESULTS: Porto-systemic gradient decreased after TIPS (6.0±2.1 mmHg vs 15.8±4.8 mmHg, P<0.001). Patients were divided in two groups according to initial body mass index. After TIPS, normal weight patients had an increase in dry lean mass (from 10.9±5.9 kg to 12.7±5.6 kg, P=0.031) and TBW (from 34.5±7.6 L to 40.2±10.8 L,P=0.007), as well as insulin (from 88.9±49.2 pmol/L to 164.7±107.0 pmol/L,P=0.009) and HOMA-IR (from 3.36%±2.18% to 6.18%±4.82%,P=0.023). In overweight patients only FFA increased significantly (from 0.59±0.24 mmol/L to 0.93±0.34 mmol/L, P=0.023).CONCLUSION: TIPS procedure is effective in lowering portal pressure in patients with portal hypertension and improves body composition without significant changes in metabolic parameters. | Jonathan Montomoli Peter Holland-Fischer Giampaolo Bianchi Henning GrФnbk Hendrik Vilstrup Giulio Marchesini Marco Zoli | 2010 | World Journal of Gastroenterology2010，16，3： | 3 |
| 8 | Utility of endoscopic ultrasound in pancreatitis:A review显示文摘The close proximity of the endoscopic ultrasound probe to the pancreas results in superior spatial resolution compared to CT scan and MRI. In addition, endoscopic ultrasound (EUS) is a minimally invasive procedure that does not share the relatively high complication rate of ERCP. Due to these advantages, EUS has evolved into an important technique to assess pancreatobiliary disease. This review will discuss the role of EUS in patients with pancreatitis. The indications can be divided into acute pancreatitis and chronic pancreatitis. In acute pancreatitis, EUS is used to determine the etiology; in suspected chronic pancreatitis it is helpful to establish the diagnosis. Lastly, this review will discuss biliary pancreatitis with suspicion for persistent choledocholithiasis. | Maged K Rizk Henning Gerke | 2007 | World Journal of Gastroenterology2007，13，47： | 2 |
