| 1 | 冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。 | Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi | 2019 | 中华心血管病杂志2019，47，1： | 17 |
| 2 | Cytoprotective role of heme oxygenase-1 and heme degradation derived end products in liver injury显示文摘The activation of heme oxygenase-1(HO-1) appears to be an endogenous defensive mechanism used by cells to reduce inflammation and tissue damage in a number of injury models. HO-1, a stress-responsive enzyme that catabolizes heme into carbon monoxide(CO), biliverdin and iron, has previously been shown to protect grafts from ischemia/reperfusion and rejection.In addition, the products of the HO-catalyzed reaction, particularly CO and biliverdin/bilirubin, have been shown to exert protective effects in the liver against a number of stimuli, as in chronic hepatitis C and in transplanted liver grafts. Furthermore, the induction of HO-1 expression can protect the liver against damage caused by a number of chemical compounds. More specifically, the CO derived from HO-1-mediated heme catabolism has been shown to be involved in the regulation of inflammation; furthermore, administration of low concentrations of exogenous CO has a protective effect against inflammation. Both murine and human HO-1 deficiencies have systemic manifestations associated with iron metabolism, such as hepatic overload(with signs of a chronic hepatitis) and iron deficiency anemia(with paradoxical increased levels of ferritin).Hypoxia induces HO-1 expression in multiple rodent,bovine and monkey cell lines, but interestingly, hypoxia represses expression of the human HO-1 gene in a variety of human cell types(endothelial cells, epithelial cells, T cells). These data suggest that HO-1 and CO are promising novel therapeutic molecules for patients with inflammatory diseases. In this review, we present what is currently known regarding the role of HO-1 in liver injuries and in particular, we focus on the implications of targeted induction of HO-1 as a potential therapeutic strategy to protect the liver against chemically induced injury. | Clarice Silvia Taemi Origassa Niels Olsen Saraiva Cmara | 2013 | World Journal of Hepatology2013，5，10： | 17 |
| 3 | Intestinal barrier: A gentlemen's agreement between microbiota and immunity显示文摘Our body is colonized by more than a hundred trillion commensals, represented by viruses, bacteria and fungi. This complex interaction has shown that the microbiome system contributes to the host's adaptation to its environment, providing genes and functionality that give flexibility of diet and modulate the immune system in order not to reject these symbionts. In the intestine,specifically, the microbiota helps developing organ structures, participates of the metabolism of nutrients and induces immunity. Certain components of the microbiota have been shown to trigger inflammatory responses, whereas others, anti-inflammatory responses.The diversity and the composition of the microbiota,thus, play a key role in the maintenance of intestinal homeostasis and explain partially the link between intestinal microbiota changes and gut-related disorders in humans. Tight junction proteins are key molecules for determination of the paracellular permeability. In the context of intestinal inflammatory diseases, the intestinal barrier is compromised, and decreased expression and differential distribution of tight junction proteins is observed. It is still unclear what is the nature of the luminal or mucosal factors that affect the tight junctionproteins function, but the modulation of the immune cells found in the intestinal lamina propria is hypothesized as having a role in this modulation. In this review,we provide an overview of the current understanding of the interaction of the gut microbiota with the immune system in the development and maintenance of the intestinal barrier. | Andrea Moro Caricilli Angela Castoldi Niels Olsen Saraiva Cmara | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，1： | 11 |
| 4 | INT-767 improves histopathological features in a dietinduced ob/ob mouse model of biopsy-confirmed nonalcoholic steatohepatitis显示文摘AIM To characterize the efficacy of the dual FXR/TGR5 receptor agonist INT-767 upon histological endpoints in a rodent model of diet-induced and biopsy-confirmed non-alcoholic steatohepatitis(NASH).METHODS The effects of INT-767 on histological features of NASH were assessed in two studies using Lep^(ob/ob)(ob/ob) NASH mice fed the AMLN diet(high fat with transfat, cholesterol and fructose). In a proof-of-conceptstudy, Lep^(ob/ob)(ob/ob) NASH mice were first dosed with INT-767(3 or 10 mg/kg for 8 wk). A second ob/ob NASH study compared INT-767(3 and 10 mg/kg) to obeticholic acid(OCA)(10 or 30 mg/kg; 16 wk). Primary histological endpoints included qualitative and quantitative assessments of NASH. Other metabolic and plasma endpoints were also assessed. A comparative assessment of INT-767 and OCA effects on drug distribution and hepatic gene expression was performed in C57 Bl/6 mice on standard chow. C57 Bl/6 mice were orally dosed with INT-767 or OCA(1-30 mg/kg) for 2 wk, and expression levels of candidate genes were assessed by RNA sequencing and tissue drug levels were measured by liquid chromatography tandem-mass spectrometry.RESULTS INT-767 dose-dependently(3 and 10 mg/kg, PO, QD, 8 wk) improved qualitative morphometric scores on steatohepatitis severity, inflammatory infiltrates and fibrosis stage. Quantitative morphometric analyses revealed that INT-767 reduced parenchymal collagen area, collagen fiber density, inflammation(assessed by Galectin-3 immunohistochemistry) and hepatocyte lipid droplet area following INT-767 treatment. In a comparative study(16 wk), the FXR agonists OCA(10 and 30 mg/kg) and INT-767(3 and 10 mg/kg) both improved NASH histopathology, with INT-767 exerting greater therapeutic potency and efficacy than OCA. Mechanistic studies suggest that both drugs accumulate similarly within the liver and ileum, however, the effects of INT-767 may be driven by enhanced hepatic, but not ileal, FXR function. CONCLUSION These findings confirm the potential utility of FXR and dual FXR/TGR5 activation as disease intervention strategies in NASH. | Jonathan D Roth Michael Feigh Sanne S Veidal Louise KD Fensholdt Kristoffer T Rigbolt Henrik H Hansen Li C Chen Mathieu Petitjean Weslyn Friley Niels Vrang Jacob Jelsing Mark Young | 2018 | World Journal of Gastroenterology2018，24，2： | 7 |

| 6 | Comparative transcriptomics of Central Asian Vitis vinifera accessions reveals distinct defense strategies against powdery mildew显示文摘Grape powdery mildew(PM),caused by the biotrophic ascomycete Erysiphe necator,is a devastating fungal disease that affects most Vitis vinifera cultivars.We have previously identified a panel of V.vinifera accessions from Central Asia with partial resistance to PM that possess a Ren1-like local haplotype.In this study,we show that in addition to the typical Ren1-associated late post-penetration resistance,these accessions display a range of different levels of disease development suggesting that alternative alleles or additional genes contribute to determining the outcome of the interaction with the pathogen.To identify potential Ren1-dependent transcriptional responses and functions associated with the different levels of resistance,we sequenced and analyzed the transcriptomes of these Central Asian accessions at two time points of PM infection.Transcriptomes were compared to identify constitutive differences and PM-inducible responses that may underlie their disease resistant phenotype.Responses to E.necator in all resistant accessions were characterized by an early up-regulation of 13 genes,most encoding putative defense functions,and a late down-regulation of 32 genes,enriched in transcriptional regulators and protein kinases.Potential Ren1-dependent responses included a hotspot of co-regulated genes on chromosome 18.We also identified 81 genes whose expression levels and dynamics correlated with the phenotypic differences between the most resistant accessions‘Karadzhandahal’,DVIT3351.27,and O34-16 and the other genotypes.This study provides a first exploration of the functions associated with varying levels of partial resistance to PM in V.vinifera accessions that can be exploited as sources of genetic resistance in grape breeding programs. | Katherine C H Amrine Barbara Blanco-Ulate Summaira Riaz Dániel Pap Laura Jones Rosa Figueroa-Balderas M Andrew Walker Dario Cantu | 2015 | Horticulture Research2015，2，1： | 3 |
| 7 | Parameters of a severe disease course in ulcerative colitis显示文摘AIM:To detect high risk patients with a progressive disease course of ulcerative colitis(UC) requiring immunosuppressive therapy(IT).METHODS:A retrospective,multicenter analysis of 262 UC patients from eight German tertiary inflammatory bowel disease centres was performed.Patients were divided into two groups depending on the patients need to initiate immunosuppressive therapy in the disease course.A comparison between the two groups was made with regard to demographics,clinical and laboratory parameters obtained within three months after UC diagnosis and the response to first medical therapy.Using this data,a prognostic model was established to predict the individual patients probability of requiring an immunosuppressive therapy.RESULTS:In 104(39.7%) out of 262 patients,UC therapy required an immunosuppressive treatment.Patients in this group were significantly younger at time of diagnosis(HR = 0.981 ± 0.014 per year,P = 0.009),and required significantly more often a hospitalisation(HR = 2.5 ± 1.0,P < 0.001) and a systemic corticosteroid therapy at disease onset(HR = 2.4 ± 0.8,P < 0.001),respectively.Response to steroid treatment was significantly different between the two groups of patients(HR = 5.2 ± 3.9 to 50.8 ± 35.6 compared to no steroids,P = 0.016 to P < 0.001).Furthermore,in the IT group an extended disease(HR = 3.5 ± 2.4 to 6.1 ± 4.0 compared to proctitis,P = 0.007 to P = 0.001),anemia(HR = 2.2 ± 0.8,P < 0.001),thrombocytosis(HR = 1.9 ± 1.8,P = 0.009),elevated C-reactive protein(CRP)(HR = 2.1 ± 0.9,P < 0.001),and extraintestinal manifestations in the course of disease(HR = 2.6 ± 1.1,P = 0.004) were observed.Six simple clinical items were used to establish a prognostic model to predict the individual risk requiring an IT.This probability ranges from less than 2% up to 100% after 5 years.Using this,the necessity of an immunosuppressive therapy can be predicted in 60% of patients.Our model can determine the need for an immunosuppressive drug therapy or if a 'watch and wait' approach is reasonable already early in the treatment course of UC.CONCLUSION:Using six simple clinical parameters,we can estimate the patients individual risk of developing a progressive disease course. | Andreas Stallmach Luisa Nickel Thomas Lehmann Bernd Bokemeyer Martin Bürger Dietrich Hüppe Wolfgang Kruis Susanna Nikolaus Jan C Preiss Andreas Sturm Niels Teich Carsten Schmidt | 2014 | World Journal of Gastroenterology2014，20，35： | 2 |
