LC／MS／MS法测定全血中马钱子碱和士的宁的含量

目的建立定量分析人全血中马钱子碱和士的宁的高效液相色谱质谱联用法。方法应用Oasis^TM MCX小柱进行固相萃取法提取，XTerra^TM RP18色谱柱分离。结果在该条件下，人血中马钱子碱和士的宁的线性范围为0．01—5．0μg／ml，最小检出限为0．2ng／ml；马钱子碱和士的宁在0．01—5．0μg／ml浓度范围内的回收率均在80％以上。结论高效液相色谱质谱联用法可定量测定血中马钱子碱和士的宁。

清末民初北京八大胡同娼妓业变化初探

清末民初是中国社会的变革时期，传统社会的各个方面受到了前所未有的挑战。这一时期，中国社会的现代化进程日益发展，社会传统价值观念渐趋改变，实利之风日益盛行，娼妓业也随之发生了重要的变化。妓女逐渐丧失了过去那种“艺妓”的性质，而上层文人对妓女品第的强调和对往昔“诗意”的想像与怀念，实质上表现了他们对往昔社会氛围的追思，这种心理也揭示出了一部分人对充斥着低级趣味的“现代性”的担忧和抗拒。

While the Chinese elements may be commonly known, it is unlikely foreign audiences are aware of the name of the paper itself. Scrolls for traditional Chinese painting are drawn on Xuan paper.     

4种终末宿主土耳其斯坦东毕吸虫cox1和nad1基因的序列分析

收集黑龙江省大庆地区牛源、绵羊源、绒山羊源和山羊源土耳其斯坦东毕吸虫,以SDS-蛋白酶K法抽提其基因组DNA,用特异性引物通过PCR扩增土耳其斯坦东毕吸虫成虫细胞色素C氧化酶亚基1基因(cox1)和烟酰胺腺嘌呤二核苷酸脱氢酶亚基1基因(nad1)并进行测序,应用Chromas和DNAStar软件分析扩增产物的变异情况.结果表明,大庆地区4种终末宿主土耳其斯坦东毕吸虫cox1基因均为1 125 bp,nad1基因均为518 bp;且其线粒体基因存在差异,cox1的同源性为99.0%～99.7%,nad1的同源性为98.3%～99.4%.
