Among which,one of perspectives is to analyze the biblical metaphors in the novel. A closer reading of the book shows that the Cain allusion is an unifying theme, for the author once refers Cane as Cain, and most of the characters in the novel are blacks who are believed to be descendant of Cain because of the color of their skin as well as the same suffering of isolation and alienation. Here a study of the Cain allusion in the novel is presented with focus on Karintha's story in the first part of Cane.展开更多

Methods: Based on the principal component analysis of element contents in Chinese herbs, the effects of 25 chemical elements in the 11 kinds of Chinese herbs in the caine kidney mixture have been analyzed. Results: The traditional Chinese medicines of rehmannia, astragalus, mulberry, salvia miltiorrhiza, rhubarb in the caine kidney mixture play a major role in the treatment of chronic renal failure. Conclusion: The principal component analysis is very practical in the compatibility of medicines and concentrated prescriptions.展开更多

文摘目的建立一种QuEChERS-液相色谱-串联质谱法同时测定水产品中11种卡因类麻醉剂及其3种代谢物残留量的分析方法。方法样品经乙腈提取,无水MgSO4和NaCl除水,再经100 mg N-丙基乙二胺(primary secondary amine,PSA)进行净化,后过0.22μm有机微孔滤膜,经液相色谱-串联质谱进行定性定量分析。结果11种卡因类麻醉剂及其3种代谢物在0.01~5.00μg/L质量浓度范围内呈良好的线性关系,相关系数(r)为0.99529~0.99989,11种卡因类麻醉剂及其3种代谢物的方法检出限(limit of detection,LOD)为0.05~2.00μg/kg,方法定量限(limit of quantification,LOQ)为0.15~5.00μg/kg。在南美白对虾、鲤鱼、多宝鱼3种基质中,分别进行1倍LOQ、2~2.5倍LOQ和10倍LOQ 3个水平的加标试验,11种卡因类麻醉剂及其3种代谢物在3种添加水平中的回收率分别为71.3%~114.2%、71.2%~107.0%、70.4%~104.5%,相对标准偏差分别为0.7%~11.2%、0.5%~11.5%以及0.8%~14.2%。利用该方法对市售的50批次不同品种的水产品进行检测,结果表明在4批次产品中有卡因类麻醉剂检出,其余46批产品未检出,检出率8%;检出的项目主要为三卡因、苯佐卡因、间氨基苯甲酸和对氨基苯甲酸,含量在5.68~90.80μg/kg,其余10种化合物均未被检出。结论该方法操作简单快捷,具有较高的灵敏度、准确度和精密度,且可同时测定水产品中的多种卡因类麻醉剂,适用于批量样品的测定,具有较高的实际应用意义,可为食品安全监测提供有力的技术支持。
