1Post-traumatic hepatic artery pseudoaneurysm treated with endovascular embolization and thrombin injection显示文摘Post-traumatic hepatic artery pseudoaneurysm is unc-ommon,appearing in approximately 1%of hepatic trauma cases.Most are extrahepatic(80%)and have a late onset.Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications,especially breakage.Currently the treatment of choice is endovascular embolization with coils or the exclusion of the pseudoaneurysm using other intravascular devices.Recently there have been accounts of a treatment that combines embolization with coils and image-guided percutaneous human thrombin injection.We present a case of post-traumatichepatic artery pseudoaneurysm that was successfully treated using this combined technique.Lloret Esta Francisco López Conesa Asunción Capel Alemán Antonio Robles Campos Ricardo Reus Pintado Manuel Marín Hernández Caridad 2010World Journal of Hepatology2010,2,2:9
2Porous media grain size distribution and hydrodynamic forces effects on transport and deposition of suspended particles显示文摘The effects of porous media grain size distribution on the transport and deposition of polydisperse suspended particles under different flow velocities were investigated. Selected Kaolinite particles(2–30 μm) and Fluorescein(dissolved tracer) were injected in the porous media by step input injection technique. Three sands filled columns were used: Fine sand,Coarse sand, and a third sand(Mixture) obtained by mixing the two last sands in equal weight proportion. The porous media performance on the particle removal was evaluated by analysing particles breakthrough curves, hydro-dispersive parameters determined using the analytical solution of convection–dispersion equation with a first order deposition kinetics, particles deposition profiles, and particle-size distribution of the recovered and the deposited particles. The deposition kinetics and the longitudinal hydrodynamic dispersion coefficients are controlled by the porous media grain size distribution. Mixture sand is more dispersive than Fine and Coarse sands. More the uniformity coefficient of the porous medium is large, higher is the filtration efficiency. At low velocities, porous media capture all sizes of suspended particles injected with larger ones mainly captured at the entrance.A high flow velocity carries the particles deeper into the porous media, producing more gradual changes in the deposition profile. The median diameter of the deposited particles at different depth increases with flow velocity. The large grain size distribution leads to build narrow pores enhancing the deposition of the particles by straining.Nasre-Dine Ahfir Ahmed Hammadi Abdellah Alem HuaQing Wang Gilbert Le Bras Tariq Ouahbi 2017Journal of Environmental Sciences2017,29,3:6

5Liver steatosis in hepatitis C patients显示文摘There is controversy regarding some aspects of hepatitis C virus(HCV) infection-associated liver steatosis,and their relationship with body fat stores. It has classically been found that HCV,especially genotype 3,exerts direct metabolic effects which lead to liver steatosis. This supports the existence of a so called viral steatosis and a metabolic steatosis,whichwould affect HCV patients who are also obese or diabetics. In fact,several genotypes exert metabolic effects which overlap with some of those observed in the metabolic syndrome. In this review we will analyse the pathogenic pathways involved in the development of steatosis in HCV patients. Several cytokines and adipokines also become activated and are involved in 'pure' steatosic effects,in addition to inflammation. They are probably responsible for the evolution of simple steatosis to steatohepatitis,making it difficult to explain why such alterations only affect a proportion of steatosic patients.Emilio González-Reimers Geraldine Quintero-Platt Melchor Rodríguez-Gaspar Remedios Alemán-Valls Onán Pérez-Hernández Francisco Santolaria-Fernández 2015World Journal of Hepatology2015,7,10:3

7Factors associated with early virological response to peginterferon-α-2a/ribavirin in chronic hepatitis C显示文摘AIM: To evaluate the impact of sociodemographic/clinical factors on early virological response (EVR) to pegin-terferon/ribavirin for chronic hepatitis C (CHC) in clinical practice. METHODS: We conducted a multicenter, cross-sectional, observational study in Hepatology Units of 91 Spanish hospitals. CHC patients treated with peginterferon α-2a plus ribavirin were included. EVR was defined as undetectable hepatitis C virus (HCV)-ribonucleic acid (RNA) or ≥ 2 log HCV-RNA decrease after 12 wk of treatment. A bivariate analysis of sociodemographic and clinical variables associated with EVR was carried out. Independent factors associated with an EVR were analyzed using a multiple regression analysis that included the following baseline demographic and clinical variables: age (≤ 40 years vs > 40 years), gender, race, educational level, marital status and family status, weight, alcohol and tobacco consumption, source of HCV infection, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and gamma glutamyl transpeptidase (GGT) (≤ 85 IU/mL vs > 85 IU/mL), serum ferritin, serum HCV-RNA concentration (< 400 000 vs ≥ 400 000), genotype (1/4 vs 3/4), cirrhotic status and ribavirin dose (800/1000/1200 mg/d).RESULTS: A total of 1014 patients were included in the study. Mean age of the patients was 44.3 ± 9.8 years, 70% were male, and 97% were Caucasian. The main sources of HCV infection were intravenous drug abuse (25%) and blood transfusion (23%). Seventyeight percent were infected with HCV genotype 1/4 (68% had genotype 1) and 22% with genotypes 2/3. The HCV-RNA level was > 400 000 IU/mL in 74% of patients. The mean ALT and AST levels were 88.4 ± 69.7 IU/mL and 73.9 ± 64.4 IU/mL, respectively, and mean GGT level was 82 ± 91.6 IU/mL. The mean ferritin level was 266 ± 284.8 μg/L. Only 6.2% of patients presented with cirrhosis. All patients received 180 mg of peginterferon α-2a. The most frequently used ribavirin doses were 1000 mg/d (41%) and 1200 mg/d (41%). The planned treatment duration was 48 wk for 92% of patients with genotype 2/3 and 24 wk for 97% of those with genotype 1/4 (P < 0.001). Seven percent of patients experienced at least one reduction in ribavirin or peginterferon α-2a dose, respectively. Only 2% of patients required a dose reduction of both drugs. Treatment was continued until week 12 in 99% of patients. Treatment compliance was ≥ 80% in 98% of patients. EVR was achieved in 87% of cases (96% vs 83% of patients with genotype 2/3 and 1/4, respectively; P < 0.001). The bivariate analysis showed that patients who failed to achieve EVR were older (P < 0.005), had higher ALT (P < 0.05), AST (P < 0.05), GGT (P < 0.001) and ferritin levels (P < 0.001), a diagnosis of cirrhosis (P < 0.001), and a higher baseline viral load (P < 0.05) than patients reaching an EVR. Age < 40 years [odds ratios (OR): 0.543, 95%CI: 0.373-0.790, P < 0.01], GGT < 85 IU/mL (OR: 3.301, 95%CI: 0.192-0.471, P < 0.001), low ferritin levels (OR: 0.999, 95%CI: 0.998-0.999, P < 0.01) and genotype other than 1/4 (OR: 4.716, 95%CI: 2.010-11.063, P < 0.001) were identified as independent predictors for EVR in the multivariate analysis. CONCLUSION: CHC patients treated with peginterferon-α-2a/ribavirin in clinical practice show high EVR. Older age, genotype 1/4, and high GGT were associated with lack of EVR.Javier García-Samaniego Miriam Romero Rafael Granados Remedios Alemán Miguel Jorge Juan Dolores Suárez Ramón Pérez Gregorio Castellano Carlos González-Portela 2013World Journal of Gastroenterology2013,19,12:2
8Adipokines,cytokines and body fat stores in hepatitis Cvirus liver steatosis显示文摘AIM: To identify patients with or without liver steatosis and its severity in treatment-na?ve patients affected by hepatitis C virus(HCV) infection.METHODS: We included 56 HCV infected patients, and assessed the amount of liver fat by histomorphometry, and its relationships with fat and lean mass at different parts of the body(by densitometry), hormones [insulin, homeostatic model assessment(HOMA)], adipokines(resistin, adiponectin, leptin), and cytokines(tumor necrosis factor α, interleukin-6).RESULTS: Although the intensity of liver steatosis is related to trunk fat mass and HOMA, 33% of patients showed no liver steatosis, and this finding was not related to body mass index or genotype. Besides trunkfat mass, no other factor was related to the presence or not of liver steatosis, or to the intensity of it, by multivariate analysis. Lean mass was not related to liver steatosis. Adiponectin levels were lower among patients. No differences were observed in leptin and resistin.CONCLUSION: Steatosis in HCV infection is common(67.2%), and closely related to trunk fat, and insulin resistance, but not with leg fat mass or adipokines.emilio gonzález-reimers javier lópez-prieto geraldine quintero-platt ricardo pelazas-gonzález m remedios alemán-valls onán pérez-hernández m joséde-la-vega-prieto m angeles gómez-rodríguez candelaria martín-gonzález francisco santolaria-fernández 2016World Journal of Hepatology2016,8,1:2

11S-adenosyl-methionine decreases ethanol-induced apoptosis in primary hepatocyte cultures by a c-Jun N-terminal kinase activity-independent mechanism显示文摘AIM:To determine the role of c-Jun N-terminal kinase(JNK)activity in ethanol-induced apoptosis and themodulation of this signaling cascade by S-Adenosyl-methionine(AdoMet).METHODS:Primary hepatocyte cultures werepretreated with 100 μmol/L SP600125,a selective JNKinhibitor,1 mL/L DMSO or 4 mmol/L AdoMet and thenexposed to 100 mmo/L ethanol.Hepatocyte apoptosiswas determined by the TUNEL and DNA ladder assays.JNK activity and its inhibition by SP600125 and AdoMetwere determined by Western blot analysis of c-junphosphorylation and Bid fragmentation.SP600125 andAdoMet effects on the apoptotic signaling pathway weredetermined by Western blot analysis of cytochrome crelease and pro-caspase 3 fragmentation.The AdoMeteffect on glutathione levels was measured by Ellman'smethod and reactive oxygen species(ROS)generationby cell cytometry.RESULTS:The exposure of hepatocytes to ethanolinduced JNK activation,c-jun phosphorylation,Bidfragmentation,cytochrome c release and pro-caspase 3cleavage;these effects were diminished by SP600125,and caused a significant decrease in ethanol-inducedapoptosis(P<0.05).AdoMet exerted an antioxidanteffect maintaining glutathione levels and decreasing ROSgeneration,without a significant effect on JNK activity,and prevented cytochrome c release and pro-caspase 3cleavage. CONCLUSION:The JNK signaling cascade is a keycomponent of the proapoptotic signaling pathwayinduced by ethanol.JNK activation may be independentfrom ROS generation,since AdoMet which exertedantioxidant properties did not have a significant effect onJNK activity.JNK pathway modulator agents and AdoMetmay be components of promising therapies for alcoholicliver disease(ALD)treatment.Maria del Pilar Cabrales-Romero Lucrecia Márquez-Rosado Samia FatteI-Fazenda Cristina Trejo-Solis Evelia Arce-Popoca Leticia Alemán-Lazarini Saúl Villa-Trevineo 2006World Journal of Gastroenterology2006,12,12:2
