Blow-up Mechanism of Classical Solutions to Quasilinear Hyperbolic Systems in the critical case

Chinese Annals of Mathematics,Series B 2006年第1期27卷 53-66页

作者： Tatsien LI Dedicated

This paper deals with the blow-up phenomenon, particularly, the geometric blow-up mechanism, of classical solutions to the Cauchy problem for quasilinear hyperbolic systems in the critical case. We prove that it is still the envelope of the same family of characteristics which yields the blowup of classical solutions to the Cauchy problem in the critical case.

Under the proposed framework,a class of existing stability criteria can be extended to determine the stability of a class of neutral type systems in a critical case,i.e.,the spectral radius of the principal neutral term（matrix D in this paper）is equal to ***,an interesting property of the extended criteria is *** examples are presented to demonstrate the effectiveness of the proposed framework.

Experience of treating severe cases of 2019 novel coronavirus pneumonia in Changde area

引用

中华危重病急救医学 2020年第1期32卷 10-12页

作者： Jin Xin Fang Yimin Huang Shaohua Luo Lin Qin Yunjian Zhou Rui Peng Yue Yang Mingshi Ai Yuhang Department of critical Medicine Xiangya Third Hospital Central South University Changsha 410000 Hunan China

Since the cluster of the 2019 novel coronavirus (2019-nCoV) pneumonia, a large number of patients gathered, the mortality of critical patients has remained high and the treatment was unclear. In this outbreak, Hunan Changde region immediately set up a hospital and intensive care unit. The patients relieved through respiratory support, hemodynamics management, nutritional support, the application of antiviral drugs, analgesic and sedation. The treatment experience in severe cases of 2019-nCov pneumonia patients were summarized as follows: in terms of respiratory support, we needed to pay attention to the advantages of high-flow nasal cannula oxygen therapy (HFNC) and the intervention of mechanical ventilation, pay attention to the ventilator parameters, and adopt prone position timely. In the aspects of fluid resuscitation and volume management, we should pay attention to the characteristics of severe patients'' volume status, perform early evaluation, and clinicians should focused on hemodynamic management beside the bed. In the aspect of nutritional support and evaluation and maintenance of intestinal function, early enteral nutrition should be adopted in time. However, the trade-off between the risk of intestinal function and nutritional support in patients with mechanical ventilation and the antiviral benefits of Kaletra needed to be reevaluated, the optimized way of analgesia and sedation was adopted, at the same time, the usage and side effects of antiviral drugs should be paid attention to. We should grasp the opportunity of transportation for severe patients. It is suggested that some warning scores should be used to facilitate early recognition of patients with severe infection and then they should be earlier transferred to the designated hospital for intensive care.
