| 1 | Resin infiltration of deproteinised natural occlusal subsurface lesions improves initial quality of fissure sealing显示文摘The aim of this ex vivo study was to evaluate the infiltration capability and rate of microleakage of a low-viscous resin infiltrant combined with a flowable composite resin(RI/CR) when used with deproteinised and etched occlusal subsurface lesions(International Caries Detection and Assessment System code 2). This combined treatment procedure was compared with the exclusive use of flowable composite resin(CR) for fissure sealing. Twenty premolars and 20 molars revealing non-cavitated occlusal carious lesions were randomly divided into two groups and were meticulously cleaned and deproteinised using Na OCl(2%). After etching with HCl(15%), 10 premolar and 10 molar lesions were infiltrated(Icon/DMG; rhodamine B isothiocyanate(RITC)-labelled) followed by fissure sealing(G-?nial Flo/GC; experimental group, RI/CR). In the control group(CR), the carious fissures were only sealed. Specimens were cut perpendicular to the occlusal surface and through the area of the highest demineralisation(DIAGNOdent pen, Ka Vo). Using confocal laser-scanning microscopy, the specimens were assessed with regard to the percentage of caries infiltration, marginal adaption and internal integrity. Within the CR group, the carious lesions were not infiltrated. Both premolar(57.9% ± 23.1%) and molar lesions(35.3% ± 22.1%) of the RI/CR group were uniformly infiltrated to a substantial extent, albeit with significant differences(P = 0.034). Moreover, microleakage(n = 1) and the occurrence of voids(n = 2) were reduced in the RI/CR group compared with the CR group(5 and 17 specimens,respectively). The RI/CR approach increases the initial quality of fissure sealing and is recommended for the clinical control of occlusal caries. | Andrej M Kielbassa Ina Ulrich Rita Schmidl Christoph Schuller Wilhelm Frank Vanessa D Werth | 2017 | International Journal of Oral Science2017，9，2： | 4 |
| 2 | Impact of mobile health and medical applications on clinical practice in gastroenterology显示文摘Mobile health apps (MHAs) and medical apps (MAs) are becoming increasinglypopular as digital interventions in a wide range of health-related applications inalmost all sectors of healthcare. The surge in demand for digital medical solutionshas been accelerated by the need for new diagnostic and therapeutic methods inthe current coronavirus disease 2019 pandemic. This also applies to clinicalpractice in gastroenterology, which has, in many respects, undergone a recentdigital transformation with numerous consequences that will impact patients andhealth care professionals in the near future. MHAs and MAs are considered tohave great potential, especially for chronic diseases, as they can support the selfmanagementof patients in many ways. Despite the great potential associated withthe application of MHAs and MAs in gastroenterology and health care in general,there are numerous challenges to be met in the future, including both the ethicaland legal aspects of applying this technology. The aim of this article is to providean overview of the current status of MHA and MA use in the field ofgastroenterology, describe the future perspectives in this field and point out someof the challenges that need to be addressed. | Sven Kernebeck Theresa S Busse Maximilian D Bottcher Jurgen Weitz Jan Ehlers Ulrich Bork Didactics Educational Research in Health | 2020 | World Journal of Gastroenterology2020，26，29： | 2 |
| 3 | Bifunctional chimeric SuperCD suicide gene -YCD: YUPRT fusion is highly effective in a rat hepatoma model显示文摘AIM: To investigate the effects of catalytically superior gene-directed enzyme prodrug therapy systems on a rat hepatoma model.METHODS: To increase hepatoma cell chemosensitivity for the prodrug 5-fluorocytosine (5-FC), we generated a chimeric bifunctional SuperCD suicide gene, a fusion of the yeast cytosine deaminase (YCD) and the yeast uracil phosphoribosyltransferase (YUPRT) gene.RESULTS: In vitro stably transduced Morris rat hepatoma cells (MH) expressing the bifunctional SuperCD suicide gene (MH SuperCD) showed a clearly marked enhancement in cell killing when incubated with 5-FC as compared with MH ceils stably expressing YCD solely (MH YCD) or the cytosine deaminase gene of bacterial origin(MH BCD), respectively. In vivo, MH SuperCD tumors implanted both subcutaneously as well as orthotopically into the livers of syngeneic ACI rats demonstrated significant tumor regressions (P<0.01) under both high dose as well as low dose systemic 5-FC application,whereas MH tumors without transgene expression (MH naive) showed rapid progression. For the first time, an order of in vivo suicide gene effectiveness (SuperCD>>YCD > > BCD > > > negative control) was defi ned as a result of a directin vivo comparison of all three suicide genes.CONCLUSION: Bifunctional SuperCD suicide gene expression is highly effective in a rat hepatoma model,thereby significantly improving both the therapeutic index and the efficacy of hepatocellular carcinoma killing by fluorocytosine. | Florian Graepler Marie-Luise Lemken Wolfgang A Wybranietz Ulrike Schmidt Irina Smirnow Christine D GroB Martin Spiegel Andrea Schenk Schenk Hansj(o|¨)rg Graf Ulrike A Lauer Reinhard Vonthein Michael Gregor Sorin Armeanu Michael Bitzer Ulrich M.Lauer | 2005 | World Journal of Gastroenterology2005，11，44： | 2 |

| 5 | Interferon-γ inhibits ghrelin expression and secretion via a somatostatin-mediated mechanism显示文摘AIM:To investigate if and how the proinflammatory cytokine interferon γ(IFNγ) affects ghrelin expression in mice.METHODS:The plasma concentration of ghrelin,andgastric ghrelin and somatostatin expression,were examined in wild-type mice and mice infected with Helicobacter pylori(H.pylori).Furthermore,ghrelin expression was examined in two achlorhydric mouse models with varying degrees of gastritis due to bacterial overgrowth.To study the effect of IFNγ alone,mice were given a subcutaneous infusion of IFNγ for 7 d.Finally,the influence of IFNγ and somatostatin on the ghrelin promoter was characterized.RESULTS:H.pylori infection was associated with a 50% reduction in ghrelin expression and plasma concentration.Suppression of ghrelin expression was inversely correlated with gastric inflammation in achlorhdyric mouse models.Subcutaneous infusion of IFNγ suppressed fundic ghrelin mRNA expression and plasma ghrelin concentrations.Finally,we showed that the ghrelin promoter operates under the control of somatostatin but not under that of IFNγ.CONCLUSION:Gastric infection and inflammation is associated with increased IFNγ expression and reduced ghrelin expression.IFNγ does not directly control ghrelin expression but inhibits it indirectly via somatostatin. | Jesper AB Strickertsson Kristina BV DΦssing Anna JM Aabakke Hans-Olof Nilsson Thomas VO Hansen Ulrich Knigge Andreas Kjr Torkel Wadstrm Lennart Friis-Hansen | 2011 | World Journal of Gastroenterology2011，17，26： | 2 |
