Teaching of medical ethics is a very important issue in medical education. In previous two year, we have successfully taught medical ethics in the fourth-year medical student with problem-based learning. The students also responded that its advisable if the course be extended into their premedical curriculum. Their excellent reports for the SARS-related events inspiring us that this might be a good topic for discussion.

教导医学伦理在医学教育中是极为重要的一环，我们曾尝试以「问题为导向学习」之教学方式，进行医学伦理学之教授，学生之反应甚佳，但也建议应在刚入大学未上基础医学时先行传授基本概念。

Cinnamomea, antrocamphin A was purified from previous ethanol extraction using bioactivity-guided fractionation. As results, the antrocamphin A could significantly inhibit NO and PGE2 autacoids production in LPS-induced RAW 264.7 macrophage cells. Meanwhile, the mRNA and protein expression levels of iNOS and COX-2 were inhibited by antrocamphin A in a dose-dependent manner. Antrocamphin A also reduced the translocation of NF-κB induced by LPS, which was associated with the prevention of the degradation of I-κB, and subsequently decreased p65/p50 proteins level in the nucleus. This is the first report demostrating the A.

接著并以活性为导向的分离策略，从樟芝子实体乙醇抽出物中分离出具抗发炎活性成分antrocamphin A，续利用LPS诱导小鼠巨噬细胞（RAW 264.7）产生发炎的模式，解析antrocamphin A之抗发炎机制，结果证实antrocamphin A确可有效抑制一氧化氮自由基和前列腺素的生成，透过蛋白质表现分析得知，antrocamphin A之抗发炎活性是经由抑制一氧化氮生成酵素和第二型环氧酵素的mRNA表现，进而抑制了一氧化氮生成酵素、第二型环氧酵素和核转录因子-κB等酵素之表现。
