Strategies for the sustainable development of China in the post-epidemic era

Countries around the world are facing enormous challenges in their economic and social development as COVID-19 continues to spread, resulting in slower economic recovery in the post-pandemic era. Considering the impact of economic growth on future sustainable development in this new era, green economic recovery (GER) can achieve a win-win situation between economic recovery and environmental improvement and bring forth environmentally sustainable economic growth. This research first lists related COVID-19 literature surveys and GER policies in the post-pandemic era in China. Based on a comparative study of the international experience of GER policy practices, this paper then analyzes the opportunities and challenges China faces for GER and puts forward countermeasures and suggestions on how to promote its sustainable development in the post-epidemic era. We believe our research presents useful enlightenments for sustainable economic and social development in the post-epidemic era. © 2022 ERP Environment and John Wiley & Sons Ltd.

mTOR-Mediated Cell Death and Infection

The battle between pathogens and hosts is an ongoing phenomenon that has been studied for centuries. Although multicellular organisms have developed sophisticated immune systems to defend against pathogens, pathogens are often able to successfully infect their hosts. To enhance their chance of survival, pathogens can hijack the host's metabolism, which serves as a critical control point that can potentially impact infections. Mammalian target of rapamycin (mTOR) is the nutrient sensor and central regulator of metabolism in innate and adaptive immune cells. Rapamycin, a drug targeting the mTOR pathway, has been widely used in clinical practice for decades and is relatively safe. However, some unexpected infections occur after long-term administration of rapamycin, indicating the presence of a close relationship between mTOR signaling and the infection process. In this manuscript, we briefly review the mTOR pathway and the current clinical use of rapamycin;we also summarize the role of the mTOR pathway in immune cell death, including apoptosis, necroptosis, pyroptosis, and ferroptosis, and its impact on anti-infection immunity. Finally, potential application of mTOR inhibitor in coronavirus disease 2019 clinical therapy is discussed.

Design and engineering application of medical oxygen supply system in novel coronavirus pneumonia treatment hospital

Respiratory supporting, as an important medical treatment for new coronavirus pneumonia patients, must be effectively guaranteed by medical oxygen supply. However, the medical oxygen system designed and configured by the existing hospitals according to the current specifications cannot meet the oxygen needs for patients with new coronavirus pneumonia. This paper aimed to study the design of medical oxygen system in new coronavirus pneumonia emergency hospital. By investigating the oxygen treatment plan for the novel coronavirus pneumonia patients in the health emergency hospital, the oxygen treatment characteristics of different patients were studied. The oxygen characteristics of different respiratory support terminals were explored to study the oxygen demands of new coronavirus pneumonia emergency hospitals. Through calculating flow rates of medical gas system air source referring to 'technical code for medical gases engineering', the proportion coefficient of severe patients converted into respiratory distress patients was introduced, and the model of calculating flow rates of medical oxygen system air source in emergency hospital was proposed. The cases were verified in a typical health emergency hospital that the developed calculation flow model of medical oxygen source met the demands of hospital oxygen. The outcomes provide a reference for the design and construction of medical oxygen in such health emergency hospitals.

The comovement between epidemics and atmospheric quality in emerging countries

This research examines the short- or long-term relationship between epidemics and atmospheric quality via panel data of 69 countries over the period 1990-2019. By employing the panel univariate LM unit root test, panel cointegration tests with multiple structural breaks, and FMOLS estimations as well as the panel vector error correction model (VECM), we find that a bi-directional relationship among variables exists in the full sample. More importantly, from a long-term perspective we also note that the impact of epidemics on atmospheric quality is negative. Therefore, we hypothesize that this may be related to the retaliatory emissions of companies after epidemics and poor government supervision. For a more in-depth investigation, we take CO2 emissions of the industrial and transportation sectors as the proxy variables and see that the more developed an economy is, the greater is the cointegration between epidemics and atmospheric quality. Our research offers implications for policy makers, such that improving atmospheric quality is an important way to prevent epidemics, and in order to alleviate and eliminate the spread of epidemics governments should pay more attention to environmental control.
