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.

Repurchase of B share is the key of study and discussion.The author thinkthat securities repurchase has been an convention of international capitalmarket and that B share public enterprises should be allowed to repurchasetheir shares according to the adjustment of their capital requirement in order touphold share price and the image of enterprises.The sixth chapter,thedemerger of A Share and B Share,proposes the demerger of the equity of anenterprise which has issued both B share and A share under special conditions,in the situation that the phenomena of different prices for the same equity isdeteriorating,and the tentative plan to set up one pure B-share publicenterprise and one A-share enterprise.In the end,this chapter demonstratesthe feasibility from the view of law and finance.
