| 1 | Sodium arsenite reduces severity of dextran sulfate sodium-induced ulcerative colitis in rats显示文摘The histopathological features and the associated clinical findings of ulcerative colitis (UC) are due to persistent inflammatory response in the colon mucosa. Interventions that suppress this response benefit UC patients. We tested whether sodium arsenite (SA) benefits rats with dextran sulfate sodium (DSS)-colitis. The DSS-colitis was induced by 5% DSS in drinking water. SA (10 mg/kg; intraperitoneally) was given 8 h before DSS treatment and then every 48 h for 3 cycles of 7, 14 or 21 d. At the end of each cycle rats were sacrificed and colon sections processed for histological examination. DSS induced diarrhea, loose stools, hemoccult positive stools, gross bleeding, loss of body weight, loss of epithelium, crypt damage, depletion of goblet cells and infiltration of inflammatory cells. The severity of these changes increased in the order of Cycles 1, 2 and 3. Treatment of rats with SA significantly reduced this severity and improved the weight gain. | Joshua J.

| 2 | Lessons from “real life experience” of rifaximin use in the management of recurrent hepatic encephalopathy显示文摘BACKGROUND Hepatic encephalopathy(HE)is a major complication of cirrhosis with independent prognostic significance.The current management of HE is mainly based on lactulose.Rifaximin has been shown to decrease the risk of HE recurrence in patients with episodic forms.HE can also be persistent.However,there is no drug support recommendation for rifaximin use in this setting.AIM To assess the effectiveness of rifaximin in the management of recurrent episodes of HE and recurrent acute exacerbations on persistent HE,in“real life conditions”.METHODS In this retrospective study,using a within-subjects design,we collected data of patients treated with rifaximin for HE in two liver diseases centers,during the six-month period before and during the six-month period after the initiation of rifaximin.The primary effectiveness endpoint was the total number of HE events involving hospitalization.RESULTS Rifaximin was introduced for prevention of recurrent HE episodes in 29 out of 62 patients with normal mental status between episodes and for prevention of recurrent acute exacerbations on persistent HE in 33 out of 62 patients.In the“prevention of recurrent HE episodes”group,fewer HE events(0.79 vs 1.78;P=0.013)were reported during the period of time when rifaximin was used.In the“prevention of recurrent acute exacerbations on persistent HE”group,there was no significant difference in the number of HE-events(1.48 vs 1.77;P=0.582).CONCLUSION In this real-life experience,the effectiveness of rifaximin was confirmed in the prevention of HE episodes recurrence but was not proved in the prevention of acute exacerbations recurrence on persistent HE. | Fiona Chautant Maeva Guillaume Marie-Angèle Robic Jean-François Cadranel Jean-Marie Peron Hortensia Lison Charlène Cool Christophe Bureau Véronique Duhalde | 2020 | World Journal of Hepatology2020，12，1： | 3 |
| 3 | Exploring the factors affecting carbon and nutrient concentrations in tree biomass components in natural forests,forest plantations and short rotation forestry显示文摘Background: Coupling biomass models with nutrient concentrations can provide sound estimations of carbon and nutrient contents, enabling the improvement of carbon and nutrient balance in forest ecosystems. Although nutrient concentrations are often assumed to be constant for some species and specific tree components, at least in mature stands,the concentrations usually vary with age, site index and even with tree density. The main objective of this study was to evaluate the sources of variation in nutrient concentrations in biomass compartments usually removed during harvesting operations, covering a range of species and management conditions: semi-natural forest, conventional forest plantations and short rotation forestry(SRF). Five species(Betula pubescens, Quercus robur, Eucalyptus globulus, Eucalyptus nitens and Populus spp.) and 14 genotypes were considered. A total of 430 trees were sampled in 61 plots to obtain 6 biomass components:leaves, twigs, thin branches, thick branches, bark and wood Aboveground leatos biomass was pooled togetto The concentrations of C, N, K P, Ca, Mg, S; Fe, Mn, Cu, Zn and B were measured and the total biomass of each sampled tree and plot were determined. The data were analysed using boosted regression trees and conventional techniques.Results: The main sources of variation in nutrient concentrations were biomass component > > genotype(species)-age >tree diameter. The concentrations of Ca, Mg and K were most strongly affeaed by genotype and age. The concentrations of P, K Ca, Mg; S and Cu in the wood component decreased with age, whereas C concentrations increased, with a trend to reach 50% in the older trees. In the SRF, interamerican poplar and P. trichocorpa genotypes were comparatively more efficient in terms of Ca and K nutrient assimilation index(NAI)(+65-85%) than eucalypts, mainly because leafless biomass can be removed. In the conventional eucalypt plantations(rotation 15 years), debarking the wood at logging(savings of225% of Ca and 254% of Mg for ￡ globulus) or the use of selected genotypes(savings of 45% of P and 35% of Ca) will provide wood at a relatively lower nutrient cost. Considering all the E globulus genotypes together, the management for pulp with removal of debarked wood shows NAI values well above(x 1.7-x 3.9) the ones found for poplar or eucalypt SRF and also higher(x 1.6-X4.0) than the ones found for oak and birch managed in medium or long rotations.The annual rates of nutrient removal were low in the native broadleaved species but the rates of available soil nutrients removed were high as compared to poplar or eucalypts. Management of native broadleaved species should consider nutrient stability through selection of the biomass compartments removed.(Continued on next page)(Continued from previous page)Conclusions: The nutrient assimilation index is higher in poplar grown under short rotation forestry management than in the other systems considered. Nutrient management of fast growing eucalyptus plantations could be improved by selecting efficient genotypes and limiting removal of wood. The values of the nutrient assimilation index are lower in the natural stands of native broadleaved species than in the other systems considered. | Roque Rodriguez-Soalleiro Cristina Eimil-Fraga Esteban Gomez-Garda Juan Daniel Garcia-Villabrille Alberto Rojo-Alboreca Fernando Munoz Nerea Oliveira Hortensia Sixto Cesar Perez-Cruzado | 2018 | Forest Ecosystems2018，5，4： | 3 |
