It is proved that Uhlenbeck’s factorization is energy decreasing. And a method of estimating the energy of a uniton by the uniton number is given.展开更多

This process involves complex changes in a variety of immune molecules and cells,such as cytokines,complements,lymphocytes,and leukocytes. With the gradual deepening of studies on the development and progression of SAP,the role of immune dysregulation in the pathogenesis of SAP has attracted more and more attention. In this article,we review the advances in research on the immune dysregulation in SAP and the immunotherapy of this disease through exploring the formation of excessive immune response and immune suppression as well as their mutual transformation.展开更多
