Stabilization of Functional System with Markovian Switching

There are many papers related to stability, some on suppression or on stabilization are one type of them. Functional differential systems are common and important in practice. They are special situations of neutral differential systems and generalization of ordinary differential systems. We discussed conditions on suppression on functional system with Markovian switching in our previous work: “Suppression of Functional System with Markovian Switching”. Based on it, by slightly modifying and adding some conditions, we get this paper. In this paper, we will study a functional system whose coefficient satisfies the local Lipschitz condition and the one-sided polynomial growth condition under Markovian switching. By introducing two appropriate intensity Brownian noise, we find the potential explosion system stabilized.

桥本氏甲状腺炎患者食物特异性IgG抗体水平关系的研究分析

目的探索桥本氏甲状腺炎患者与食物不耐受之间的关系,为临床治疗提供参考。方法观察分析2020年4月至2021年5月在深圳恒生医院诊断桥本氏甲状腺患者(153例)食物不耐受的发生情况,采用条带免疫印迹法检测桥本氏甲状腺炎患者食物特异性免疫球蛋白(immunoglobulin,Ig)G抗体(共14项)的表达情况。结果在纳入的153名桥本氏甲状腺炎患者中,食物特异性IgG抗体检测总阳性率高达64.05%(98/153),其中对鸡蛋食物不耐受的发生率高达52.29%(80/153),其次是牛奶22.22%(34/153)。分层分析发现不同年龄段的食物不耐受总体发生率差异无统计学意义(χ^(2)=0.3868,P=0.5340),相对于≤30岁组,>30岁组的患者对鸡蛋、牛奶(χ^(2)值分别为4.1727和16.0912,P值均<0.05)的食物不耐受发生率均有所下降。结论桥本氏甲状腺炎患者普遍存在食物不耐受,且食物不耐受的发生率和性别无关,但随着年龄增加,对牛奶、鸡蛋等食物的不耐受发生率明显下降。
