简介：摘要：目的：分析阿莫西林联合奥美拉唑治疗溃疡性胃炎的效果及不良反应。方法：将选取的72例，随机分为36例一组，对照组行奥美拉唑治疗，观察组联合阿莫西林与奥美拉唑治疗，观察患者症状改善和疗效差异。结果：两组患者治疗后症状改善为观察组更好，治疗有效率更高（P<0.05）。不良反应方面对比，两组间差异无统计学意义（p>0.05）。结论：治疗溃疡性胃炎采取联合用药方式，不会增加患者的不良反应，还能尽快缓解患者不适症状，使临床疗效得到提升。

简介：【摘要】目的：分析海南省申报医疗器械注册体系核查、生产许可（含延续、变更）检查，以期提升各医疗器械企业（含注册人、生产企业）质量管理水平，切实履行好企业主体责任，保障产品安全、有效和质量可控。方法：汇总分析海南省2023年168家次医疗器械注册体系核查、生产许可检查时发现的缺陷。结论：通过汇总分析海南省医疗器械注册体系核查、生产许可检查发现的问题，发现企业在机构与人员、文件管理、设计开发等方面的缺陷占比较多，存在一定的风险隐患。因此建议对我省医疗器械企业仍需加强监管，深化风险防控，进一步督促医疗器械企业落实主体责任、强化产品质量管理和风险防范。

简介：AbstractObjective:The aim of this work was to explore the feasibility of in vivo and non-invasive monitoring of deuterium/hydrogen (2H/1H) exchange at the metabolic level upon exposure to heavy water (2H2O).Methods:The healthy female mice were randomly assigned to two groups after day 0 when both mice received standard drinking water. The treated mouse was fed with 2H2O (80%, v/v) and the control mouse fed with standard drinking water (H2O) over next 13 days. Real-time mass spectrometric analysis of volatile metabolism emitted through breathing and the skin was performed on days 1, 2, 3, 10, 12, and 13. Animal experiment was approved by the Laboratory Animal Ethics Committee of Jinan University (approval No. 20161117163322) on October 29, 2021.Results:We observed a replacement of 1H by 2H in 52 mass spectral features (60 2H/1H isotopologue pairs) for the mouse fed with 2H2O, but not for the control mouse. These included pyruvic acid and lactic acid, lysine and methyl-lysine as well as short-chain fatty acids comprising acetic acid, propionic acid, butyric acid and valeric acid.Conclusion:Secondary electrospray ionization-high resolution mass spectrometry allows monitoring in vivo2H-incorporation of metabolites in a non-invasive and real-time setup and opens new opportunities to use 2H tracing to extend current metabolic studies, especially those with a focus on anaerobic glycolysis, lysine methylation and gut microbiome via monitoring of short-chain fatty acids.
