Sepsis 3.0 is defined as a life-threatening organ dysfunction caused by the host' uncontrol response to infection, with poor prognosis, high morbidity and fatality. Sepsis is one of the main causes of death in severe patients. As lack of comprehensive recognition of its pathogenesis, there were not specific treatment on it. It is reported that the T-cell immunoglobulin and mucin-domain-containing molecule (Tim) of Tim-1 play critical role in sepsis inflammation, immune tolerance and apoptosis, which is relative specific factor in assessment of sepsis prognostic and treatment efficiency, indicating that it could be a novel target in sepsis as well as provide a novel direction. This article mainly stated the discovery, structure, distribution and immune effect of Tim-1 as well as the possible role of TIM-1in immunosuppression, lymphocyte proliferation and apoptosis, in order to provide reference for further research the treatment of sepsis.

Sepsis-induced myocardial dysfunction (SIMD) has a high morbidity and mortality, and seriously threatens human health. However, the pathogenesis of the SIMD is still unclear. The previous studies have showed that the SIMD can adversely affect cardiac function through a variety of direct or indirect mechanism, such as autonomic nervous system function damage, pro-inflammatory mediators and activated immune cells induced cardiomyopathy. There is no uniform diagnostic criteria and treatment options. A stable and reliable animal model plays important role in the study that determine the pathogenesis, pathophysiological processes and treatment of SIMD. At present, there are many animal models of cardiac dysfunction caused by sepsis, unfortunately there is no stable, reliable and specific animal model at present. Therefore, it is important to construct a stable and reliable model for studying SIMD. The unified standard of cardiac dysfunction is conducive to the integration and further research. This review focused on pathogenesis of SIMD, routine ways of animal model of SIMD, observation index and basic research to provide references for the researcher to choose the proper animal model.

The new type coronavirus disease 2019 (COVID-19) is a contagious disease of severe lung inflammation induced by 2019 novel coronavirus (2019-nCoV). The World Health Organization (WHO) nomenclature of the newly discovered coronavirus was 2019-nCoV and the disease caused by 2019-nCoV was named COVID-19 on January 12, 2020. After 2019-nCoV invasion into a human body, it can stimulate the human immune system and engender a large number of cytokines, triggering a cytokine storm, resulting in severe infection, acute lung injury, multiple organ dysfunction, etc. Therefore, theoretically, the removal of over-production of cytokines can avoid the occurrence of cytokine storm and reduce the incidence of severe critical COVID-19 and serious poor prognosis. In this review, the authors systematically reviewed the past published reports related to the occurrence of cytokine storm in sepsis resulting in deterioration of disease situation, and recently they analyzed the therapeutic effects of patients with severe critical COVID-19 using endotoxin adsorption membrane for treatment in the disease course, further providing the effective clinical evidence of applying endotoxin adsorption membrane for treatment of COVID-19.
