In the present study, we developed and validated a simple and sensitive gradient elution liquid chromatography tandem mass spectrometry （LC-MS/MS） method for quantification of doxorubicin in rabbit plasma. Daunorubicin was used as an internal standard （IS）. The doxorubicin and IS were extracted with ethyl acetate from plasma samples. The chromatographic separations were achieved on a C18 column （2.1 mm×50 mm, 2.5μm） configured with a C18 guard column （2.1 mm×10 mm, 2.5 μm）. The mobile phase of 0.1% formic acid-water solution and acetonitrile was delivered using a gradient elution program at a flow rate of 0.4 mL/min. The temperature for column was maintained at 40 ℃. The electrospray ionization （ESI） source was operated in the positive ion mode, and the quantification was conducted using multiple reaction monitoring （MRM） of the transitions m/z 544.07→396.96 and m/z 528.06→321.05 for doxorubicin and IS, respectively. The calibration curve of doxorubicin was linear （r 〉 0.999） within the range of 2-600 ng/mL. The lower limit of quantification was 2 ng/mL. The relative errors of intra-day and inter-day accuracies ranged from -2.48% to 0.18% and from -3.78% to 1.94%, respectively. The relative standard deviations of intra-day and inter-day precisions were less than 8.65% and 6.41%, respectively. The method exhibited satisfactory results in terms of specificity, sensitivity, matrix effect, recovery and stability. The newly developed LC-MS/MS method was reliable to monitor doxorubicin concentrations in rabbit plasma.

冷诱导RNA结合蛋白(cold inducible RNA-binding protein,CIRP)是一种RNA结合蛋白,属于冷休克蛋白家族,广泛表达于各种组织细胞中,且在冷应激、缺氧、紫外线照射等过程中过量表达[1]。CIRP在细胞内外的定位不同,则其作用不同。细胞内CIRP(intracellular CIRP,iCIRP)是在细胞质内合成的,然后再回到细胞核并作为RNA伴侣与mRNA非特异性结合,在细胞核内起到稳定RNA,防止RNA降解并调节RNA转录的作用;细胞质内iCIRP则调节mRNA的翻译重编程;而iCIRP被释放到细胞外,即细胞外CIRP(extracellular CIRP,eCIRP),则发挥着炎症介质的作用[1-2]。近年来研究发现CIRP在感染性/非感染性炎症疾病和缺血-再灌注损伤中发挥着重要作用[3]。

以Bi(NO3)3·5H2O为原料,乙醇为介质,KBr和/或十六烷基三甲基溴化铵(CTAB)为溴源,采用溶剂热法合成了不同结构和性能的Bi OBr微纳米材料,通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)、红外光谱仪(FTIR)、紫外-可见漫反射光谱(UV-Vis DRS)及比表面积和孔隙度分析仪对产物进行了表征.结果表明,溴源(KBr,CTAB)对Bi OBr的结晶特性和形貌有重要影响,其中采用双溴源且KBr与CTAB摩尔比为3∶7时制得的Bi OBr(K∶C=3∶7)光催化剂在模拟太阳光下具有最优的光催化性能,光照20 min后对废水中卡马西平的降解速率常数是以KBr为溴源制备的Bi OBr(K)的4.10倍和以CTAB为溴源制备的Bi OBr(C)的2.14倍.Bi OBr(K∶C=3∶7)优异的光催化活性可归因于其高暴露的(110)晶面、表面羟基、疏松的片层状形貌及较大的比表面积和孔体积.活性物种淬灭实验结果表明,Bi OBr(K∶C=3∶7)的光催化活性主要源于光生空穴、羟基自由基和电子.
