根据现阶段环境类本科专业微生物教学的现状与存在的问题,提出环境微生物学教学实践与改革的发展方向。课堂教学应重视基础知识教育,增加课堂教学内容的新颖性和前沿性,提升学生的学习兴趣,运用多种教学方法,多方面增强教学效果。实验教学应重视基础验证性实验教学,鼓励综合性实验教学,拓展设计性实验教学,并建立合理的实验课程考核评价体系,重视学生学习过程的评价。  相似文献

明代宋诗选本现可考者约有十五家。它们虽是对时人过度轻视宋诗的反驳,但也没有超越崇唐抑宋的时代风气,在选诗标准上多持以唐存宋的态度。明代宋诗选本保留了不少珍贵的宋诗文献,成为清代宋诗选本的文献来源之一,对清代宋诗复兴起过重要作用,但作为文献又有诸多缺陷,给清代选本带来不好的影响。  相似文献

In order to comply with the requirements for a drug listed in China, the study was developed to compare the pharmacokinetics and relative bioavailability of two different enteric formulations of omeprazole (OPZ) in healthy Chinese subjects. A total of 32 volunteers participated in the study. Plasma concentrations were analyzed by nonstereospecific liquid chromatography/tandem mass spectrometric (LC-MS/MS) method. After administration of a single 40-mg dose of the two OPZ formulations, the comparative bioavailability was assessed by calculating individual AUC0−t (the area under the concentration-time curve from time zero to the last measurable concentration), AUC0−∞ (the area under the concentration-time curve extrapolated to infinity), C max (the maximum observed concentration), and T peak (the time to C max) values of OPZ, 5-hydroxyomeprazole (OH-OPZ), and omeprazole sulfone (OPZ-SFN), respectively. The 90% confidence intervals (CIs) of AUC0−t , AUC0−∞, and C max were 85.4%–99.0%/88.8%–98.6%/87.6%–99.4%, 85.5%–99.2%/89.0%–98.6%/88.5%–101.3%, and 72.3%–87.6%/79.6%–91.1%/88.4%–99.1% for OPZ/OH-OPZ/OPZ-SFN, respectively, and T peak values did not differ significantly. In this study, the test formulation of OPZ in fasting healthy Chinese male volunteers met the Chinese bioequivalance standard to the reference formulation based on AUC, C max, and T peak.  相似文献

Objective: To study the role of calpain in the mechanism of oxidative cataract through detecting the level of intracellular free Ca2 , the expression and proteolytic activity of calpain in the lens epithelial cells (LECs) of H2O2-induced cataract. Methods: Rat lenses were cultured in vitro and cataract was induced by H2O2. The level of intracellular free Ca2 was measured by fluorescence determination with fura-2/AM. The expression of m-calpain protein in LECs was detected with immunohistochemical method. The proteolytic activity in LECs was measured using a fluorogenic synthetic substrate. Results: There were significant differences of the level of intracellular free Ca2 (P=0.001, 0.000, 0.000), the expression of m-calpain (P=0.001, 0.000, 0.000) and the proteolytic activity of calpain (P=0.001, 0.000, 0.000) between H2O2-induced and control group at 6, 12 and 24 h, respectively. Conclusions: H2O2 can increase intracellular free Ca2 , then enhance the expression and proteolytic activity of calpain which may play a role in the mechanism of oxidative cataract of rat.  相似文献

This study presents a rapid, specific and sensitive liquid chromatography/tandem mass spectrometry (LC-MS/MS) assay for determination of risperidone (RIS) in human serum using paroxetine as an internal standard (IS). An Alltima-C 18separation. The analysis was performed by selected reaction monitoring (SRM) method, and the peak area of the m/z 411.3→ 191.1 transition for RIS was measured versus that of the m/z 330.1→192.1 transition for IS to generate the standard curves. The assay linearity of RIS was confirmed over the range 0.25~50.00 ng/ml and the limit of quantitation was 0.05 ng/ml. The linear range corresponds well with the serum concentrations of the analytes obtained in clinical pharmacokinetic studies. Intraday and interday relative standard deviations were 1.85%~9.09% and 1.56%~4.38%, respectively. The recovery of RIS from serum was in the range of 70.20%~84.50%. The method was successfully applied to investigate the bioequivalence between two kinds of tablets (test versus reference products) in 18 healthy male Chinese volunteers. The result suggests that two formulations are bioequivalent.  相似文献

广枣提取液对小鼠免疫功能和运动耐力的影响   总被引:11,自引:0,他引:11  
观察了广枣提取液对小鼠免疫功能、运动耐力的影响。结果表明:广枣提取液可明显增加小鼠耐缺氧时间,延长小鼠负重游泳时间,降低运动后小鼠血乳酸水平,显著提高其心肌组织中SOD活力;同时明显增加小鼠脾脏/体重、胸腺/体重比值,增强小鼠对巨噬细胞的吞噬能力.提高小鼠的细胞免疫、体液免疫功能。提示广枣提取液具有显著促进小鼠免疫功能及显著提高小鼠运动耐力的功效。  相似文献

英语一般现在时除表示现在时间以外,还可以用来表达过去与将来时间。从一般现在时的实质现联性出发,以其两个基本特征——时间上的双向联系和心理上的现联性为依托,运用转喻认知机制对英语一般现在时语法形式和语法意义之间存在的矛盾进行了阐释,从而揭示一般现在时丰富的语法表意功能背后所隐藏的认知理据。  相似文献
