Ten Years’ Chinese-Canadian Collaboration in Undergraduate Education in Fujian Agriculture and Forestry University of China: Curriculum Development     

Songliang Wang  Claude Caldwell  Liqing Wei  Haiyan Su 《Frontiers of Education in China》2015,10(3):427-438

The Fujian Agriculture and Forestry University-Nova Scotia Agricultural College (FAFU-NSAC) 2 + 2 undergraduate program initiated in 2003 is a model for creative collaboration between China and Canada in undergraduate education. This paper addresses the achievements of the program development and highlights the process for successful curriculum development in the joint program. The authors also discuss some issues and challenges related to the Chinese-Canadian experience in undergraduate education, and propose some recommendations for further collaborations including: enlarging the scale of qualified programs; proposing a systematic baseline to control the program at a macro-level; simplifying coordination procedures with foreign partners; and adjusting the emphasis of courses introduced by the cooperative partner from quantity to quality.  相似文献

Chlorogenic acid prevents acetaminophen-induced liver injury: the involvement of CYP450 metabolic enzymes and some antioxidant signals     

Chun Pang  Yu-chen Sheng  Ping Jiang  Hai Wei  Li-li Ji 《Journal of Zhejiang University. Science. B》2015,16(7):602-610

Chlorogenic acid (CGA), a polyphenolic compound, is abundant in fruits, dietary vegetables, and some medicinal herbs. This study investigated the prevention of CGA against acetaminophen (AP)-induced hepatotoxicity and its engaged mechanisms. CGA reversed the decreased cell viability induced by AP in L-02 cells in vitro. In addition, CGA reduced the AP-induced increased serum levels of alanine/aspartate aminotransferase (ALT/AST) in vivo. The effect of CGA on cytochrome P450 (CYP) enzymatic (CYP2E1, CYP1A2, and CYP3A4) activities showed that CGA caused very little inhibition on CYP2E1 and CYP1A2 enzymatic activities, but not CYP3A4. The measurement of liver malondialdehyde (MDA), reactive oxygen species (ROS), and glutathione (GSH) levels showed that CGA prevented AP-induced liver oxidative stress injury. Further, CGA increased the AP-induced decreased mRNA expression of peroxiredoxin (Prx) 1, 2, 3, 5, 6, epoxide hydrolase (Ephx) 2, and polymerase (RNA) II (DNA directed) polypeptide K (Polr2k), and nuclear factor erythroid-2-related factor 2 (Nrf2). In summary, CGA ameliorates the AP-induced liver injury probably by slightly inhibiting CYP2E1 and CYP1A2 enzymatic properties. In addition, cellular important antioxidant signals such as Prx1, 2, 3, 5, 6, Ephx2, Polr2k, and Nrf2 also contributed to the protection of CGA against AP-induced oxidative stress injury.  相似文献   

匹伐他汀钙对高胆固醇血症患者动脉粥样硬化的影响（英文）     

Jing ZHAO  Hui-min YAN  Ya LI  Jia WANG  Lu HAN  Zhi-hao WANG  Meng-xiong TANG  Wei ZHANG  Yun ZHANG  Ming ZHONG 《Journal of Zhejiang University. Science. B》2015,16(5):380-387

目的:观察匹伐他汀钙对高胆固醇血症患者外周血管的影响。创新点:首次在国内发现匹伐他汀钙能够改善高胆固醇血症患者肱动脉和颈动脉血管内皮功能而且延缓其动脉粥样硬化发展,并首次证实改善内皮功能是匹伐他汀钙延缓其动脉粥样硬化发展的重要原因。方法:按照入选排除标准,选取本院高胆固醇血症患者(HC),完成超声心动图检查的40例。根据剂量不同,分为两个剂量组:1 mg剂量组20例(男性5例,女性15例,平均年龄(55.20±8.35)岁),2 mg剂量组20例(男性9例,女性11例,平均年龄(57.56±6.09)岁)。访视结束后完成超声心动图检查的HC组36例,两个剂量组分别有2人失访。治疗后1 mg剂量组18例(男性3例,女性15例,平均年龄(56.00±7.85)岁),2 mg剂量组18例(男性7例,女性11例,平均年龄(57.79±6.46)岁)。选择本院同期体检中心30例正常人作为对照(年龄和性别均与病例组匹配,男性14例,女性16例,平均年龄(54.94±6.90)岁)。所有研究对象,均经隔夜禁食12~14小时,次日清晨抽取空腹肘静脉血,测定临床生化指标。采用Sequia512彩色多普勒超声诊断仪,应用高分辩率外周血管超声技术,检测HC治疗前后肱动脉血流介导性舒张功能(FMD)、颈动脉结构和功能。结论:经匹伐他汀钙治疗8周后,高胆固醇血症患者血管功能明显改善,表现为FMD升高,僵硬度减小;颈动脉僵硬度和内中膜厚度(IMT)延缓进展与其内皮功能改善密切相关。  相似文献   

Microcalorimetry studies of the antimicrobial actions of Aconitum alkaloids     

Yan-bin Shi  Lian Liu  Wei Shao  Ting Wei  Gui-mei Lin 《Journal of Zhejiang University. Science. B》2015,16(8):690-695

The metabolic activity of organisms can be measured by recording the heat output using microcalorimetry. In this paper, the total alkaloids in the traditional Chinese medicine Radix Aconiti Lateralis were extracted and applied to Escherichia coli and Staphylococcus aureus. The effect of alkaloids on bacteria growth was studied by microcalorimetry. The power-time curves were plotted with a thermal activity monitor (TAM) air isothermal microcalorimeter and parameters such as growth rate constant (μ), peak-time (T_m), inhibitory ratio (I), and enhancement ratio (E) were calculated. The relationships between the concentration of Aconitum alkaloids and μ of E. coli or S. aureus were discussed. The results showed that Aconitum alkaloids had little effect on E. coli and had a potentially inhibitory effect on the growth of S. aureus.  相似文献

周薇 《中国轻工教育》2015,(2):21-23

国内外学者翻译和用外语编写的中医书籍日益增多,外国留学生和国外医学界对中医兴趣亦十分浓厚,但中医术语翻译重译、错译、误译严重。本文将西方翻译理论中的重要研究成果翻译伦理与中医术语翻译相结合。提出译者应区分不同的翻译任务,将中医术语分类,选择遵从再现伦理、交际伦理、服务伦理、规范伦理中的一种翻译伦理,统一翻译思路,从而避免中医术语翻译中所产生的问题。  相似文献
