2019-novel coronavirus (2019-nCov) outbreak took place in December 2019 and continues to spread around the world. By April 3, 2020, more than 1 million patients have been diagnosed with corona virus disease 2019 (COVID-19) [1]. The virus has a long incubation period, is highly contagious, and is generally susceptible to all types of people, which has a huge negative impact on people's health, economic development, and social stability [2]. However, there is still a lack of effective clinical drugs or vaccine to control the virus.
