Experts hope an experimental drug can be as effective against the novel coronavirus in people as it has been on cells in a controlled lab environment.

The US drug, remdesivir (瑞德西韦), began clinical trials（临床试验）on patients in Wuhan, Hubei province on Thursday. Other medications, including chloroquine, arbidol and darunavir have also recently been found capable of arresting viral growth in lab cells, but like remdesivir, they require more clinical trials to confirm their safety and potency on humans.

The Phase III trials for remdesivir have been approved by China’s National Medical Products Administration and is conducted by the China-Japan Friendship Hospital in Beijing and the Chinese Academy of Medical Sciences on patients at the Wuhan Jinyintan Hospital.

“A total of 761 patients will participate in two trials-one trial to assess the drugs' potency on 308 cases with mild or moderate infection, and the other on 453 severely infected patients”, Cao Bin, head of the clinical trial and vice-president of the friendship hospital, said on Wednesday.

Cao said studies have shown remdesivir is effective in inhibiting the growth of the novel coronavirus in vitro(在生物体外), meaning the procedure was done on cells in a controlled environment outside of a living organism, typically in a petri dish or test tube.

But the drug has yet to show convincing clinical evidence that it can translate its positive in vitro results into actual human patients. So, it will require strict clinical testing, Cao said.

A 35-year-old patient from the United States infected with the virus was reported seeing noticeable improvement with no obvious side effects after taking the drug, according to the New England Journal of Medicine.

Gilead Sciences, the maker of remdesivir, said in a recent statement that it has been working with government agencies on the novel coronavirus response efforts.

However, the company stressed that remdesivir is an experimental medicine that has only been used in a handful of patients, “so we do not have an appropriately full understanding of the effect of this drug ”.

It’s March, 2050. Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news. They used to read the Times, but changed to electronic newspapers many years ago.

There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news: the US dollar has risen greatly in Shanghai, one of the world’s leading business centers. Mary tells the computer to buy 5,000 dollars, and there is a quick response that it has been done.

As they watch the screen, Mary orders one of the household robots to make coffee for them. Frank disappears into the study to join a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job: he used to be in marketing and then television.

Mary has a quick look at the shopping channels—the usual selection of electric cars, household robots and cheap travel offers—before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.

Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communications systems have made it much easier to learn at home.

Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate by computer.

According to the family doctor, Louise will live to at least 130. Her wish is to work for a few decades (十年) and then spend her time on music and painting.
