There are four steps in the interaction between intestinal microbes and mucosal inflammation in genetically predisposed individuals from the viewpoints of basic and clinical aspects of inflammatory bowel disease （IBD）. The first step is an interaction between intestinal microbes or their components and intestinal epithelial cells via receptors, the second step an interaction between macrophages and dendritic cells and mucosal lymphocytes, the third step an interaction between lymphocytes and vascular endothelial cells, and the fourth step an interaction between lymphocytes and granulocytes producing proinflammatory cytokines or free radicals and mucosal damage and repair. Recent therapeutic approaches for IBD aim to block these four steps in the intestinal inflammation of patients with IBD.

The rolling of AM60 sheets for 50%reduction was analyzed with DEFORM to investigate the hot deformation process. The simulated results show that the sheet velocities at the entrance(21 mm/s) and at the exit(37 mm/s) are less and larger than roll velocity,*** the entrance to the neutral point,the velocity at the sheet surface is greater than that at the middle point of sheet in thickness,while that from the neutral point to the exit shows the opposite *** effective strain of the sheet increases from the entrance to the exit due to the continuous reduction in *** addition,the effective strain at the sheet surface reaches to 1.0 and is larger than that of 0.8 at the middle point of *** difference of effective strain in thickness direction has a much stronger effect on the recrystallized fraction than on the recrystallized grain *** minimum temperature of 347℃is obtained at the surface contacting directly with roll and the maximum temperature 388℃at the middle point of sheet in thickness.
