ABSTRACT

Human pathogenic coronaviruses can be divided into seven types, namely HCoV-229E, HCoV-OC43, HCoV-HKUl, HCoV-NL63, SARS-CoV, MERS-CoV and SARS-CoV-2. Among them, Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS) and Corona Virus Disease 2019 (COVID-19), which are caused by the last three coronaviruses respectively, are enormous threats that challenge human health and social and economic development. Despite the huge investment in drug development for pathogenic coronaviruses, there is no specifically effective anti-coronavirus drug approved so far. In this review we systematically summarize 146 representative anti-coronavirus active compounds reported in the past 20 years and list 26 potential target proteins involved in the process of viral infection and replication. In addition, we predict the target proteins of those active compounds with unclear antiviral activity mechanisms. We hope that the information will be useful to accelerate the development of new anti-coronavirus drugs. © 2020 Zhonghua Yixuehui Zazhishe. All rights reserved.

ABSTRACT

Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.
