建立了3-脱氧果糖(3-DF)初步检测的高效液相色谱(HPLC)方法。先使用气相色谱―质谱联用(GC-MS)对合成的3-DF标样进行鉴定。再采用C18反相色谱柱,流动相为乙腈-水(10%∶90%~90%∶10%)梯度洗脱60min,紫外检测波长352nm,应用2,4-二硝基苯... 建立了3-脱氧果糖(3-DF)初步检测的高效液相色谱(HPLC)方法。先使用气相色谱―质谱联用(GC-MS)对合成的3-DF标样进行鉴定。再采用C18反相色谱柱,流动相为乙腈-水(10%∶90%~90%∶10%)梯度洗脱60min,紫外检测波长352nm,应用2,4-二硝基苯肼柱前衍生法,以薄层色谱―高效液相色谱联用(TLC-HPLC)对3-DF衍生物峰进行定位,并完善衍生条件,进行方法学考察。结果表明:合成样品为3-DF;衍生条件以衍生液中1∶3添加乙酸乙酯效果最佳;3-DF衍生物峰出峰时间为15.972 min,呈尖峰,分离度良好,线性范围为0.5~8 mg/mL,方法精密度RSD为2.4%,重复性RSD为4.4%,稳定性RSD为2.4%。本检测方法稳定、可靠,可初步用于3-DF定性及相对定量。 展开更多

Objective:To explore the relationship among plasma 3-deoxyglucuronide (3-DG) level, severity of sepsis and clinical prognosis, and to provide references for the assessment of sepsis patients' condition and prognosis.Methods:120 sepsis patients and 50 health particapants in our hospital from January 2018 to December 2018 were enrolled in the observation group and the control group respectively. The plasma levels of 3-DG were measured and compared between the two groups at the time of admission. According to the 28-day prognosis of the patients in the observation group, they were divided into the survival group and the death group. The plasma 3-DG changes and acute physiology and chronic health scoring system II (APACHE II) and Glasgow coma score (GCS) were compared between the two groups at the time of enrollment, on the third day of admission, on the 7th day of admission, on the 14th day after admission. The correlation between plasma 3-DG and the severity score of sepsis patients was analyzed, and the value of plasma 3-DG in predicting the mortality of sepsis patients was analyzed by ROC.Results:The plasma concentration of 3-DG in the observation groupwas (296.38±52.97)μg/L, which was higher than that in the control group (91.06±22.38)μg/L, and the difference was statistically significant. After 28 d of hospitalization, 81 patients survived and 39 died in the observation group, with a fatality rate of 32.50%. The plasma levels of 3-DG in the survival group and the death group decreased continuously at the time of admission, the 3rd day of admission, the 7th day of admission and the 14th day of admission. The plasma 3-DG levels of survival group and fatality group decreased continuously at admission, 3rd day, 7th day and 14th day. The plasma 3-DG levels of the survival group were lower than those of the fatality group at admission, 3rd day, 7th day and 14th day. The scores of APACHE II, SOFA and MODS of the survival group and the fatality group decreased continuously at admission, 3rd day, 7th day, 14th day, 展开更多
