Currently, the anti-viral therapy has been extensively utilised to reduce the viral burden and switch off certain infectious sources for hepatitis B virus (HBV) infected patients in clinical treatment. Several pieces of existing evidence have demonstrated that large-scale coverage with anti-viral therapy has obtained a certain great contribution in hygiene and disease control. In this study, an anti-HBV mathematical model is considered and its control strategy of the drug treatment is designed. Based on the Lyapunov theory, this study derives three main theorems to propose three different control strategies, respectively, for drug treatments [inline-formula removed] and [inline-formula removed], such that all states of the anti-HBV model can finally converge to the infection-free equilibrium point [inline-formula removed] asymptotically. Especially, the designed drug treatment [inline-formula removed] or [inline-formula removed] is not a fixed value, but it is time-varying and dependent on states. In Theorem 1, the single drug treatment [inline-formula removed] without [inline-formula removed] is synthesised. Theorem 2 considers the single drug treatment [inline-formula removed] without [inline-formula removed]. In Theorem 3, the combination therapy of [inline-formula removed] and [inline-formula removed] is designed. Finally, there are several simulations to show that the proposed combination therapy is much more effective to cure HBV infected patients than the drug treatment with solely single [inline-formula removed] or single [inline-formula removed].

抗HBV数学模型的控制策略设计。

目前,在临床治疗中,抗病毒疗法已被广泛用于减少乙型肝炎病毒(HBV)感染患者的病毒负担和切断某些传染源。现有的几项证据表明,抗病毒治疗的大规模覆盖在卫生和疾病控制方面取得了一定的巨大贡献。在本研究中,考虑了一种抗HBV数学模型,并设计了其药物治疗的控制策略。本研究基于李雅普诺夫理论,推导出三个主要定理,提出三种不同的控制策略,分别用于药物治疗[去除内联公式]和[去除内联公式],使得抗HBV模型的所有状态最终都可以渐近地收敛到无感染平衡点[删除内联公式]。特别是,设计的药物治疗[inline-formula removed]或[inline-formula removed]不是一个固定值,而是随时间变化的,并且依赖于状态。在定理 1 中,合成了没有 [inline-formula removed] 的单一药物治疗 [inline-formula removed]。定理 2 考虑了没有 [inline-formula removed] 的单一药物治疗 [inline-formula removed]。在定理3中,设计了[去除内联公式]和[去除内联公式]的联合治疗。最后,有几个模拟表明,所提出的联合治疗比单独使用单一[去除内联配方]或单一[去除内联配方]的药物治疗更有效地治愈 HBV 感染患者。但它是时变的并且取决于状态。在定理 1 中,合成了没有 [inline-formula removed] 的单一药物治疗 [inline-formula removed]。定理 2 考虑了没有 [inline-formula removed] 的单一药物治疗 [inline-formula removed]。在定理3中,设计了[去除内联公式]和[去除内联公式]的联合治疗。最后,有几个模拟表明,所提出的联合治疗比单独使用单一[去除内联配方]或单一[去除内联配方]的药物治疗更有效地治愈 HBV 感染患者。但它是时变的并且取决于状态。在定理 1 中,合成了没有 [inline-formula removed] 的单一药物治疗 [inline-formula removed]。定理 2 考虑了没有 [inline-formula removed] 的单一药物治疗 [inline-formula removed]。在定理3中,设计了[去除内联公式]和[去除内联公式]的联合治疗。最后,有几个模拟表明,所提出的联合治疗比单独使用单一[去除内联配方]或单一[去除内联配方]的药物治疗更有效地治愈 HBV 感染患者。在定理3中,设计了[去除内联公式]和[去除内联公式]的联合治疗。最后,有几个模拟表明,所提出的联合治疗比单独使用单一[去除内联配方]或单一[去除内联配方]的药物治疗更有效地治愈 HBV 感染患者。在定理3中,设计了[去除内联公式]和[去除内联公式]的联合治疗。最后,有几个模拟表明,所提出的联合治疗比单独使用单一[去除内联配方]或单一[去除内联配方]的药物治疗更有效地治愈 HBV 感染患者。
