简介：AbstractBackground:Carbon monoxide (CO) poisoning remains a major cause of accidental injuries and multiple studies have indicated that CO is also associated with significantly severe or long-term toxicity to the central nervous system. Given that CO poisoning causes serious morbidity and mortality, a better understanding of epidemiological features and clinical characteristics of acute CO poisoning in China is crucial.Methods:We collected the clinical data of acute CO poisoning in patients between November 2019 and April 2020 across Shandong province, China and analyzed its characteristics focusing on the weekly amount and the severity of the confirmed cases.Results:A total number of 21,088 acute CO poisoning cases were diagnosed. The overall incidence of acute CO poisoning was approximately 0.021%. On severity rankings, 63% of confirmed cases (n = 13,378) were mild, 27% (n = 5635) were moderate, and 10% (n = 2075) were severe. Interestingly, the coastal cities had more confirmed cases than the inland/suburban areas in Shandong. Meanwhile, the number of confirmed cases was negatively correlated with the local mean daily temperature (P = 0.0167).Conclusions:Mild acute CO poisoning cases accounted for the majority of all confirmed cases during the winter of 2019. In Shandong province, which is located in east China, residents of the coastal cities are more susceptible to CO poisoning than residents of inland cities.

简介：摘要Carbon monoxide (CO) is an odorless and colorless gas with multiple sources that include engine exhaust, faulty furnaces, and other sources of incomplete combustion of carbon compounds such as house fires. The most serious complications for survivors of consequential CO exposure are persistent neurological sequelae occurring in up to 50% of patients. CO inhibits mitochondrial respiration by speci-fically binding to the heme a3 in the active site of CIV-like hydrogen sulfide, cyanide, and phosphides. Although hyperbaric oxygen remains the cornerstone for treatment, it has variable efficacy requiring new approaches to treatment. There is a paucity of cellular-based therapies in the area of CO poisoning, and there have been recent advancements that include antioxidants and a mitochondrial substrate prodrug. The succinate prodrugs derived from chemical modification of succinate are endeavored to enhance delivery of succinate to cells, increasing uptake of succinate into the mitochondria, and providing metabolic support for cells. The therapeutic intervention of succinate prodrugs is thus potentially applicable to patients with CO poisoning via metabolic support for fuel oxidation and possibly improving efficacy of HBO therapy.

简介：基于模糊控制思想，研究了新近提出的Liu混沌系统的耦合同步。为了分析比较，首先应用线性时变稳定性理论实现Liu混沌系统的线性耦合同步。然后基于T-S模糊模型重构了Liu混沌系统，并用Lyapunov理论和耦合同步的思想推导了两个重构的Liu系统耦合同步的稳定性条件。本文的模糊耦合同步方法通过LMI方法可以迅速求取可行解，同步条件更加清晰明确、约束条件少，并可以方便地得到不同衰减率α下全局渐近稳定的充分条件。此外，设计的控制器都由线性函数构成，有利于实际应用中构造控制器。良好的仿真结果验证了本文模糊同步方法的有效性，该方法适用于符合广义Lorenz范式（GLCF）的混沌系统。

简介：讨论了新混沌系统——Liu系统的混沌同步问题，基于Lyapunov函数分别提出了单变量以及多变量的线性状态反馈控制方案，采用这两种线性控制方案均可实现Liu系统的混沌同步，线性反馈控制比起非线性控制具有结构简单、易于实现的特点，数值模拟结果验证了两种方案的可行性。
