Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.

Parthenolide is extract from feverfew, it's main component is sesquiterpene, it is commanly used in west country and is mainly used to therapy skin infection, rheumatic disorder, migraine. But recent research indicate that parthenolide can regulate many pathway of signal in the cell, inhibit the cyclooxygenase, TNF-α, interleukin-1 expression induced by lipopolysaccharide in macrophage, inhibit the iNOS expression in human monocyt, inhibit the activity of NF-κB in Hela cell, inhibit the growth of tumor cell and can relieve the myocardial ischemical reperfusion injury and so on. But the invention research about the effection of parthenolide on the VSMC is very rare in the world, so we do some research about the effection of inhibition of parthenpolide on the proliferation of VSMC and the signal transduction mechanism.

Can accelerate the bone marrow cell from G1 phase into S phase when we measure it's Cell cycle, it make S phase rate was increased .thus it promoted DNA synthesize and repaired. Mice irradiated at dose of 5.5 Gy gamma-irradiation showed timed-related decreases and restores in peripheral blood picture at day 1 through day 21, the counts of WBC of these group had taken drug has various degree to increase than irradiation control group in day 1. Grugs failed to protected the peripheral blood cell at lowest point, but seems promote their rescovery.9803 treated group was distinct. At 7days after mice were radiated in 3.5 Gy. we observed drug can Significantly hold back the decreased number of hematopoietic progenitors colony forming radiation induced. These findings indicated 9803 have a certain radioprotective activity against gammer irradiation in mice.
