| 1 | Helicobacter pylori eradication therapy for functional dyspepsia: Systematic review and meta-analysis显示文摘AIM: To evaluate whether Helicobacter pylori(H. pylori) eradication therapy benefits patients with functional dyspepsia(FD).METHODS: Randomized controlled trials(RCTs) investigating the efficacy and safety of H. pylori eradication therapy for patients with functional dyspepsia published in English(up to May 2015) were identified by searching Pub Med, EMBASE, and The Cochrane Library. Pooled estimates were measured using the fixed or random effect model. Overall effect was expressed as a pooled risk ratio(RR) or a standard mean difference(SMD). All data were analyzed with Review Manager 5.3 and Stata 12.0.RESULTS: This systematic review included 25 RCTs with a total of 5555 patients with FD. Twenty-three of these studies were used to evaluate the benefits of H. pylori eradication therapy for symptom improvement; the pooled RR was 1.23(95%CI: 1.12-1.36, P < 0.0001). H. pylori eradication therapy demonstrated symptom improvement during long-term follow-up at ≥ 1 year(RR = 1.24; 95%CI: 1.12-1.37, P < 0.0001) but not during short-term follow-up at < 1 year(RR = 1.26; 95%CI: 0.83-1.92, P = 0.27). Seven studies showed no benefit of H. pylori eradication therapy on quality of life with an SMD of-0.01(95%CI:-0.11 to 0.08, P = 0.80). Six studies demonstrated that H. pylori eradication therapy reduced the development of peptic ulcer disease compared to no eradication therapy(RR = 0.35; 95%CI: 0.18-0.68, P = 0.002). Eight studies showed that H. pylori eradication therapy increased the likelihood of treatment-related side effects compared to no eradication therapy(RR = 2.02; 95%CI: 1.12-3.65, P = 0.02). Ten studies demonstrated that patients who received H. pylori eradication therapy were more likely to obtain histologic resolution of chronic gastritis compared to those who did not receive eradication therapy(RR = 7.13; 95%CI: 3.68-13.81, P < 0.00001).CONCLUSION: The decision to eradicate H. pylori in patients with functional dyspepsia requires individual assessment. | Li-Jun Du Bin-Rui Chen John J Kim Sarah Kim Jin-Hua Shen Ning Dai | 2016 | World Journal of Gastroenterology2016，22，12： | 30 |
| 2 | Outcomes of furazolidone-and amoxicillin-based quadruple therapy for Helicobacter pylori infection and predictors of failed eradication显示文摘AIM To evaluate the outcomes of furazolidone-and amoxicillin-based quadruple therapy for treatment of Helicobacter pylori(H. pylori) infection and identify predictors of failed eradication.METHODS Patients with H. pylori infection treated with furazolidone, amoxicillin, bismuth, and proton pump inhibitor therapy(January 2015 to December 2015) who received the ^(13)C-urea breath test > 4 wk after treatment were evaluated. Demographic and clinical data including prior H. pylori treatment attempts, medication adherence, alcohol and cigarette consumption during therapy, and treatment-related adverse events were recorded by reviewing medical records and telephone surveys. H. pylori eradication rates for overall and subgroups were evaluated. Multivariate analysis was performed to identify independent predictors of failed H. pylori eradication.RESULTS Of the 992 patients treated and retested for H. pylori infection, the overall eradication rate was 94.5% [95% confidence interval(CI): 94.1%-95.9%]. H. pylori eradication rate of primary therapy was 95.0%(95%CI: 93.5%-96.5%), while that of rescue therapy was 91.3%(95%CI: 86.8%-95.8%). Among the 859 patients who completed the study protocol, 144(17%) reported treatment-related adverse events including 24(3%) leading to premature discontinuation. On multivariate analysis, poor medication adherence [adjusted odds ratio(AOR) = 6.7, 95%CI: 2.8-15.8], two or more previous H. pylori treatments(AOR = 7.4, 95%CI: 2.2-24.9), alcohol consumption during therapy(AOR = 4.4, 95%CI: 1.5-12.3), and possibly smoking during therapy(AOR = 1.9, 95%CI: 0.9-4.3) were associated with failed H. pylori eradication. CONCLUSION Furazolidone-and amoxicillin-based quadruple therapy for H. pylori infection in an area with a high prevalence of clarithromycin resistance demonstrated high eradication rates as primary and rescue therapies with a favorable safety profile. Patient education targeting abstinence from alcohol during therapy and strict medication adherence may further optimize H. pylori eradication. | Ya-Wen Zhang Wei-Ling Hu Yuan Cai Wen-Fang Zheng Qin Du John J Kim John Y Kao Ning Dai Jian-Min Si | 2018 | World Journal of Gastroenterology2018，24，40： | 18 |
| 3 | Fructo-oligosaccharide intensifies visceral hypersensitivity and intestinal inflammation in a stress-induced irritable bowel syndrome mouse model显示文摘AIM To determine whether fructo-oligosaccharide(FOS) affects visceral sensitivity, inflammation, and production of intestinal short-chain fatty acids(SCFA) in an irritable bowel syndrome(IBS) mouse model.METHODS Mice were randomly assigned to daily oral gavage of saline solution with or without FOS(8 g/kg body weight) for 14 d. Mice were further assigned to receive either daily one-hour water avoidance stress(WAS) or sham-WAS for the first 10 d. After 2 wk, visceral sensitivity was measured by abdominal withdrawal reflex in response to colorectal distension and mucosal inflammation was evaluated. Gas chromatography, real-time reverse transcription PCR, and immunohistochemistry assays were used to quantify cecal concentrations of SCFA, intestinal cytokine expression, and number of intestinal mast cells per high-power field(HPF), respectively.RESULTS Mice subjected to WAS exhibited visceral hypersensitivity and low-grade inflammation. Among mice subjected to WAS, FOS increased visceral hypersensitivity and led to higher cecal concentrations of acetic acid(2.49 ± 0.63 mmol/L vs 1.49 ± 0.72 mmol/L, P < 0.05), propionic acid(0.48 ± 0.09 mmol/L vs 0.36 ± 0.05 mmol/L, P < 0.01), butyric acid(0.28 ± 0.09 mmol/L vs 0.19 ± 0.003 mmol/L, P < 0.05), as well as total SCFA(3.62 ± 0.87 mmol/L vs 2.27 ± 0.75 mmol/L, P < 0.01) compared to saline administration. FOS also increased ileal interleukin(IL)-23 mR NA(4.71 ± 4.16 vs 1.00 ± 0.99, P < 0.05) and colonic IL-1β mR NA(2.15 ± 1.68 vs 0.88 ± 0.53, P < 0.05) expressions as well as increased mean mast cell counts in the ileum(12.3 ± 2.6 per HPF vs 8.3 ± 3.6 per HPF, P < 0.05) and colon(6.3 ± 3.2 per HPF vs 3.4 ± 1.2 per HPF, P < 0.05) compared to saline administration in mice subjected to WAS. No difference in visceral sensitivity, intestinal inflammation, or cecal SCFA levels was detected with or without FOS administration in mice subjected to sham-WAS.CONCLUSION FOS administration intensifies visceral hypersensitivity and gut inflammation in stress-induced IBS mice, but not in the control mice, and is also associated with increased intestinal SCFA production. | Bin-Rui Chen Li-Jun Du Hui-Qin He John J Kim Yan Zhao Ya-Wen Zhang Liang Luo Ning Dai | 2017 | World Journal of Gastroenterology2017，23，47： | 4 |
| 4 | 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 |
| 5 | Effect of Laminar Cooling on Phase Transformation Evolution in Hot Rolling Process显示文摘The effect of temperature variation owing to the cooling pattern(CP)on the microstructural evolution was investigated by establishing a thermomechanical coupled FE(finite element)model.A set of constitutive equations of phase transformation was implanted into the commercial FE solver MARC through the user defined subroutine CRPLAW,and the temperature field was calculated by another user defined subroutine FILM.The results show that the final microstructure is completely bainite phase for CP one,98% of bainite phase and 2% of ferrite phase for CP two,and 55% of bainite phase,35% of pearlite phase and 10% of ferrite phase for CP three. | NING Lin-xin YANG Dai-jun J Lin T A Dean | 2010 | Journal of Iron and Steel Research(International)2010，17，10： | 2 |

| 7 | Recent progress in thick-film organic photovoltaic devices:Materials,devices,and processing显示文摘A successful transfer of organic photovoltaic technologies from lab to fab has to overcome a range of critical challenges such as developing high-mobility light-harvesting materials,minimizing the upscaling losses,designing advanced solar modules,controlling film quality,decreasing overall cost,and extending long-operation lifetime.To realize large-area devices toward practical applications,much effort has been devoted to understanding the fundamental mechanism of how molecular structures,device architectures,interfacial engineering,and light management and carrier dynamics affect photovoltaic performance.Such studies addressed various fundamental issues of charge carrier behavior in organic heterojunctions primarily in terms of exciton generation dependence upon light incidence,charge transportation dependence on built-in electric field,and charge extraction versus recombination.In consideration of high-throughput roll-to-roll process for large-scale fabrication of organic photovoltaic devices,it is highly appreciable to realize high power conversion efficiencies that are highly tolerable to the film thickness.Herein we summarize the recent progress in developing thick-film organic photovoltaic devices from the perspective of efficiency-loss mechanisms,material design,and device optimization strategies,proposing guidelines for designing high-efficiency thickness-insensitive devices toward mass production. | Difei Zhang Baobing Fan Lei Ying Ning Li Christoph J Brabec Fei Huang Yong Cao | 2021 | SusMat2021，1，1： | 2 |
