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。

环氧丙烷是一种重要的有机化工原料，它不仅可以生产聚醚多元醇，进而生产聚醚酯等，它还可以生产非离子型表面活性剂、油田破乳剂、阻燃剂、农药乳化剂和润湿剂等。

Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

为大幅度提高其承载能力、传动效率和可靠性诸指标，我们创新研究出来的多种结构双曲柄环板式针摆行星传动，其特点是不仅保留着原摆线针轮行星减速器同时啮合齿数多，总法向力与总圆周力间夹角小，摆线轮与针轮齿均为硬齿面等本质上的优点；而且又具有环板式传动省去输出机构且输出轴刚性好，转臂轴承移至行星轮外，从而传递的转矩可以成倍提高的优点。

Sizing is clearly headed in the direction of neutral, and neutral divides in two directions: one is self-retention of neutral, such as the AKD, ASA cationtype Rosin, neutrase ployster and the other is a non-self-fixed neutral, such as the anion dispersed oil Rosin, anion, neutral polyester resin, and the latest research interest is the preparation, to meet the many self-retention and Rosin Sizing the performance of the Department of sizing agent, such as neutrase ployster, epoxidized Rosin, etc.

造纸施胶正朝着中性施胶方向迅猛发展，而中性施胶剂又分为两个方向，一是自身留着型中性施胶剂，如AKD、ASA、阳离子分散松香胶、中性聚酯，另一类是非自定型中性施胶剂，如阴离子中性分散松香、阴离子石油树脂、中性聚酯等，而最新型研究方向则是将二者统一起来，制备成兼具自身留着和松香系施胶性能的施胶剂，如中性聚酯，环氧化松香等。
