具有主動免疫與藥物治療控制乙肝病毒傳播的動力學(xué)模型
[Abstract]:Hepatitis B is an infectious disease caused by hepatitis B virus. Usually people take active immunization (vaccination) to prevent hepatitis B virus infection, take drug treatment to inhibit virus replication in the body of hepatitis B virus infection, so as to control the spread of hepatitis B. The main work of this paper is as follows: considering the need of clinical treatment, a pharmacokinetic model was established to analyze the drug regimen. The relationship between plasma concentration and time of different drug doses was given. The results of the model were applied to the apnea treatment of premature infants. The feasibility of drug administration was analyzed based on the criteria of safety, no waste and the ability to maintain stable efficacy. And for the treatment of children with severe illness, a personalized drug delivery scheme was designed. Considering that hepatitis B virus infection mainly comes from newborns and immune failure, a SEICR model with active immunity to control the transmission of hepatitis B virus is established. By using the theory of differential equations, sufficient conditions for the existence and global asymptotic stability of disease-free and endemic equilibrium points are given. The rationality of the results is verified by numerical simulation. The proportion of vaccinated vaccine will change the vertical infection rate and the effective contact rate between the susceptible person and the virus infected person. Then the effect of inoculation proportion vertical infection rate and effective contact rate on HBV carriers is simulated by MATLAB numerical simulation. Numerical simulation results show that active immunization can effectively control the spread of hepatitis B virus. Considering the effect of drug therapy on the control of hepatitis B virus infection, a dynamic model of hepatitis B virus transmission with drug therapy was given, in which the proportion of drug treatment was regarded as a function of time. On this basis, the objective function of the proportion of hepatitis B virus infection and drug therapy was established in order to reduce the number of hepatitis B virus infected persons. The existence of optimal treatment proportion is proved by using the sufficient condition of optimal control. Based on the principle of Pontryagin Maxima, the optimal proportion expression of drug therapy was found. The feasibility of the results was verified by numerical simulation. It was found that when the optimal proportion of drug treatment was selected, the hepatitis B virus infection rate decreased to 1 in 20 years.
