Cusp Bifurcation in the Evolution Model of Cirrhosis

Abstract In this work, a model of evolution of hepatitis B cirrhosis based on catastrophe theory was put forward, Witch can reveal the evolution of cirrhosis and then help develop effective treatment programs. The mechanism of interaction among antigen, antibody, and B cells was researched in the immunization model of hepatitis B virus. Based on the feature of hepatitis B cirrhosis, the model of hepatitis B virus immunization was improved, and an evolutionary model of hepatitis B cirrhosis was proposed.
