This paper introduces a class of insulin-glucose-glucocorticoid impulsive systems in the treatment of patients with diabetes to consider the effect of glucocorticoids. The existence and uniqueness of the positive periodic solution of the impulsive model at double fixed time is confirmed for type 1 diabetes mellitus (T1DM) using the [Formula: see text] function. Further, the global asymptotic stability of the positive periodic solution is achieved following Floquet multiplier theory and comparison principle. Additionally, the permanence of the system is confirmed in type 2 diabetes mellitus (T2DM) via the comparison theorem. Numerical analysis verifies the results of theoretical calculations and indicates that combining therapeutic strategies under hormonal interactions with the dose of exogenous insulin and glucocorticoid medicines within organisms provides more reasonable clinical strategies.
本文介绍了一类胰岛素 - 葡萄糖 - 糖皮质激素脉冲系统,用于治疗糖尿病患者时考虑糖皮质激素的作用。利用[公式:见原文]函数,证实了1型糖尿病(T1DM)在双固定时间的脉冲模型正周期解的存在性和唯一性。此外,根据Floquet乘数理论和比较原理,实现了正周期解的全局渐近稳定性。另外,通过比较定理证实了2型糖尿病(T2DM)中系统的持久性。数值分析验证了理论计算结果,并表明在生物体内激素相互作用下结合治疗策略与外源性胰岛素和糖皮质激素药物剂量可提供更合理的临床策略。
