| 2 | Covalently closed-circular hepatitis B virus DNA reduction with entecavir or lamivudine显示文摘AIM: To investigate the reduction in hepatitis B virus(HBV) covalently closed-circular DNA(ccc DNA) with entecavir(ETV) or lamivudine(LAM). METHODS: This analysis included patients who had participated in the randomized Phase Ⅲ study ETV-022 comparing ETV vs LAM in nucleos(t)ide-naive, HBe Agpositive patients. Patients received ETV(0.5 mg daily) or LAM(100 mg daily) for a minimum of 52 wk. Patients were eligible to participate in this sub-study if they had paired biopsies at baseline and week 48 with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA. The main objective was to compare changes in hepatic HBV ccc DNA and total hepatic HBV DNA at week 48 of ETV or LAM treatment, which was a secondary endpoint of study ETV-022. Additional post hoc analyses included linear regression analyses to assess associations of baseline levels and on-treatment changes of ccc DNA with other baseline factors [sex,age, serum HBV DNA, alanine aminotransferase(ALT), Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBV genotype], or ontreatment factors(changes from baseline at week 48 in serum HBV DNA, ALT, Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBe Ag loss at week 48).RESULTS: Overall, 305 patients(ETV = 159; LAM = 146) of ETV-022 had paired baseline and week 48 liver biopsies with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA, and were included in this analysis. Baseline demographics and disease characteristics were comparable between the two arms. After 48 wk, ETV resulted in significantly greater reductions in hepatic HBV ccc DNA [-0.9 log10 copies/human genome equivalent(HGEq) vs-0.7 log10 copies/HGEq; P = 0.0033] and total hepatic DNA levels(-2.1 log10 copies/HGEq vs-1.6 log10 copies/HGEq; P < 0.0001) than LAM. Virologic, biochemical, and histologic response rates at week 48 were also greater with ETV than with LAM. Baseline HBV ccc DNA levels were positively associated with baseline levels of serum HBV DNA and total hepatic HBV DNA, and negatively associated with HBV genotype F. On-treatment changes in HBV ccc DNA levels were negatively associated with baseline levels of serum HBV DNA and baseline ALT, and were positively associated with on-treatment changes in the levels of serum HBV DNA, total hepatic HBV DNA levels, and ALT, change in Knodell necroinflammatory score, and HBe Ag loss.CONCLUSION: Forty-eight weeks of ETV resulted in greater reductions in ccc DNA and total hepatic HBV DNA than LAM, but long-term therapy may be needed for ccc DNA elimination. | Scott Bowden Stephen Locarnini Ting-Tsung Chang You-Chen Chao Kwang-Hyub Han Robert G Gish Robert A de Man Miao Yu Cyril Llamoso Hong Tang | 2015 | World Journal of Gastroenterology2015,21,15: | 11 |
| 3 | Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis. | Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels | 2010 | World Journal of Gastroenterology2010,16,6: | 11 |
| 4 | Surveillance for hepatocellular carcinoma in chronic liver disease:Evidence and controversies显示文摘Primary liver cancer is the sixth most common cancer in the world and the third cause of cancer-related death.Hepatocellular carcinoma(HCC)represents more than90%of primary liver cancers and generally occurs in patients with underlying chronic liver disease such as viral hepatitis,hemochromatosis,primary biliary cirrhosis and non-alcoholic steatohepatitis.Especially cirrhotic patients are at risk of HCC and regular surveillance could enable early detection and therapy,with potentially improved outcome.We here summarize existing evidence for surveillance including ultrasound,other radiological modalities and various serum biomarkers,and current international guideline recommendations for surveillance.Ultrasound andα-fetoprotein(alone or in combination)are most frequently used for surveillance,but their sensitivities and specificities are still far from perfect,and evidence for surveillance remains weak and controversial.Various other potential surveillance tools have been tested,including serum markers as des-carboxyprothrombin,lectin-boundα-fetoprotein,and(most recently)circulating TIE2-expressing monocytes,and radiological investigations such as computed tomographyscan or magnetic resonance imaging-scan.Although early results appear promising,these tools have generally been tested in diagnostic rather than surveillance setting,and in most cases,no detailed information is available on their cost-effectiveness.For the near future,it remains important to define those patients with highest risk of HCC and most benefit from surveillance,and to restrict surveillance to these categories. | Suzanne van Meer Robert A de Man Peter D Siersema Karel J van Erpecum | 2013 | World Journal of Gastroenterology2013,19,40: | 10 |
| 5 | Neuroanatomy of lower gastrointestinal pain disorders显示文摘Chronic abdominal pain accompanying intestinal inflammation emerges from the hyperresponsiveness of neuronal,immune and endocrine signaling pathways within the intestines,the peripheral and the central nervous system.In this article we review how the sensory nerve information from the healthy and the hypersensitive bowel is encoded and conveyed to the brain.The gut milieu is continuously monitored by intrinsic enteric afferents,and an extrinsic nervous network comprising vagal,pelvic and splanchnic afferents.The extrinsic afferents convey gut stimuli to second order neurons within the superficial spinal cord layers.These neurons cross the white commissure and ascend in the anterolateral quadrant and in the ipsilateral dorsal column of the dorsal horn to higher brain centers,mostly subserving regulatory functions.Within the supraspinal regions and the brainstem,pathways descend to modulate the sensory input.Because of this multiple level control,only a small proportion of gut signals actually reaches the level of consciousness to induce sensation or pain.In inflammatory bowel disease(IBD)and irritable bowel syndrome(IBS)patients,however,long-term neuroplastic changes have occurred in the brain-gut axis which results in chronic abdominal pain.This sensitization may be driven on the one hand by peripheral mechanisms within the intestinal wall which encompasses an interplay between immunocytes,enterochromaffin cells,resident macrophages,neurons and smooth muscles.On the other hand,neuronal synaptic changes along with increased neurotransmitter release in the spinal cord and brain leads to a state of central wind-up.Also life factors such as but not limited to inflammation and stress contribute to hypersensitivity.All together,the degree to which each of these mechanisms contribute to hypersensitivity in IBD and IBS might be diseaseand even patient-dependent.Mapping of sensitization throughout animal and human studies may significantly improve our understanding of sensitization in IBD and IBS.On the long run,this knowledge can be put forward in potential therapeutic targets for abdominal pain in these conditions. | Wim Vermeulen Joris G De Man Paul A Pelckmans Benedicte Y De Winter | 2014 | World Journal of Gastroenterology2014,20,4: | 7 |
| 6 | Murine lung eosinophil activation and chemokine production in allergic airway inflammation显示文摘Eosinophils play important roles in asthma and lung infections.Murine models are widely used for assessing the functional significance and mechanistic basis for eosinophil involvements in these diseases.However,little is known about tissue eosinophils in homeostasis.In addition,little data on eosinophil chemokine production during allergic airway inflammation are available.In this study,the properties and functions of homeostatic and activated eosinophils were compared.Eosinophils from normal tissues expressed costimulation and adhesion molecules B7-1,B7-2 and ICAM-1 for Ag presentation but little major histocompatibility complex(MHC)class II,and were found to be poor stimulators of T-cell proliferation.However,these eosinophils expressed high levels of chemokine mRNA including C10,macrophage inflammatory protein(MIP)-1a,MIP-1c,MIP-2,eotaxin and monocyte chemoattractant protein-5(MCP-5),and produced chemokine proteins.Eosinophil intracellular chemokines decreased rapidly with concomitant surface marker downregulation upon in vitro culturing consistent with piecemeal degranulation.Lung eosinophils from mice with induced allergic airway inflammation exhibited increased chemokines mRNA expression and chemokines protein production and upregulated MHC class II and CD11c expression.They were also found to be the predominant producers of the CCR1 ligands CCL6/C10 and CCL9/MIP-1c in inflamed lungs.Eosinophil production of C10 and MIP-1c correlated with the marked influx of CD11bhigh lung dendritic cells during allergic airway inflammation and the high expression of CCR1 on these dendritic cells(DCs).The study provided baseline information on tissue eosinophils,documented the upregulation of activation markers and chemokine production in activated eosinophils,and indicated that eosinophils were a key chemokine-producing cell type in allergic lung inflammation. | C Edward Rose Jr Joanne A Lannigan Paul Kim James J Lee Shu Man Fu Sun-sang J Sung | 2010 | Cellular & Molecular Immunology2010,7,5: | 6 |
| 7 | Management and outcome of hepatocellular adenoma with massive bleeding at presentation显示文摘AIM To evaluate outcome of acute management and risk of rebleeding in patients with massive hemorrhage due to hepatocellular adenoma(HCA). METHODS This retrospective cohort study included all consecutive patients who presented to our hospital with massive hemorrhage(grade Ⅱ or Ⅲ) due to ruptured HCA and were admitted for observation and/or intervention between 1999-2016. The diagnosis of HCA was based on radiological findings from contrastenhanced magnetic resonance imaging(MRI) or pathological findings from biopsy or resection of the HCA. Hemorrhage was diagnosed based on findings from computed tomography or MRI. Medical records were reviewed for demographic features, clinical presentation, tumor features, initial and subsequent management, short-and long-term complications and patient and lesion follow-up. RESULTS All patients were female(n = 23). Treatment in the acute phase consisted of embolization(n = 9, 39.1%), conservative therapy(n = 13, 56.5%), andother intervention(n = 1, 4.3%). Median hemoglobin level decreased significantly more on days 0-3 in the intervention group than in the patients initially treated conservatively(0.9 mmol/L vs 2.4 mmol/L respectively, P = 0.006). In total, 4 patients suffered severe shortterm complications, which included hypovolemic shock, acute liver failure and abscess formation. After a median follow-up of 36 mo, tumor regression in nonsurgically treated patients occurred with a median reduction of 76 mm down to 25 mm. Four patients underwent secondary(elective) treatment(i.e., tumor resection) to address HCA size of > 5 cm and/or desire for future pregnancy. One case of rebleeding was documented(4.3%). None of the patients experienced long-term complication(mean follow-up time: 36 mo). CONCLUSION With a 4.3% risk of rebleeding, secondary(elective) treatment of HCA after massive hemorrhage may only be considered in patients with persistent HCA > 5 cm. | Anne J Klompenhouwer Robert A de Man Maarten GJ Thomeer Jan NM Ijzermans | 2017 | World Journal of Gastroenterology2017,23,25: | 5 |

| 9 | National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales. | Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser | 2021 | Forest Ecosystems2021,8,1: | 2 |
| 10 | Ecological damage of submerged macrophyte Myriophyllum spicatum by cell extracts from microcystin(MC)-and non-MC-producing cyanobacteria,Microcystis显示文摘To explore how decomposed Microcystis-dominant cyanobacterial blooms affect submerged macrophytes,the submerged plant Myriophyllum spicatum was exposed to cell extracts from microcystin(MC)-and non-MC-producing Microcystis strains in a laboratory experiment.Results showed that both Mcracystis cell extracts exerted obvious damages to plant biomass,photosynthesis,primary and secondary metabolism measures,and resistance of plant antioxidant systems,with MC-producing Microcystis having stronger effects due to the presence of MCs.Cyanotoxins other than MCs responsible for the negative effects from both strains needs further identification.The Shannon diversity and Chao1 indices of epiphytic and planktonic bacteria were decreased by the cell extracts from both Microcystis strains.However,epiphytic and planktonic bacterial communities responded differently to cell extracts at the genus level.The dominant genera of planktonic bacteria including Enterobacter,Pseudomonas,and Novosphingobium from phylum Proteobacteria,Chryseobacterium from phylum Bacteroidetes,and Microbacterium from Actinobacteriota in the treatments with cell extracts were previously reported to have strains with algicidal and MC-degrading capabilities.B acterial genes associated with energy production and conversion,amino acid transport and metabolism,and inorganic ion transport and metabolism,were more abundant in both treatments than the control for planktonic bacteria,but less abundant for epiphytic bacteria.We speculate that planktonic bacterial communities have the potential to use and degrade substances derived from Microcystis cell extracts,which may be beneficial for M.spicatum to alleviate damages from Microcystis.Further research is needed to verify the structure and function dynamics of epiphytic and planktonic bacteria in the interaction between cyanobacteria and submerged macrophytes. | Yunni GAO Hui YANG Xiaofei GAO Mei LI Man ZHANG Jing DONG Jingxiao ZHANG Longfei LI Xuejun LI Michele A BURFORD | 2022 | Journal of Oceanology and Limnology2022,40,5: | 2 |
