The writer of the letter was Mrs Berna-dette Giandomenico, who once suffered from APL but was cured with all-trans-retinoic acid(ATRA)(全反式维甲酸), a treatment developed by Wang and his medical team. Working at Ruijin Hospital, Wang has been devoting his life to the treatment of leukemia. He received the country’s highest honor in science and technology in 2010. Born in 1924 in Shanghai, Wang was inspired by a family friend’s experience of pursuing a career in medicine as a child. His grandmother’s death caused by typhoid further strengthened his resolve to fight against diseases and rescue patients. With outstanding academic performance, Wang became a doctor at Guangci Hospital, today’s Ruijin Hospital. In 1978, a research paper from Israeli experts gave Wang inspiration on studying how leukemia cells could become normal. His research didn’t progress as expected, though. In 1983, another research paper shed light on his study. As the paper suggested, after being treated with 13-cis-retinoic acid, white blood cells in patients with APL could become normal. Considering the difficulties and high cost of producing a drug made from 13-cis-retinoic acid, Wang’s team decided to replace that ingredient with ATRA, and they finally verified its positive effect after several months’ experiments. In 1986, the drug was first adopted in treating a five-year-old patient. It turned out successful. After eight years of research, Wang’s team eventually made the first breakthrough in the battle against APL. To make sure every APL patient could afford the medicine, Wang has not patented his research result to date. “One cannot be a real doctor if one does not have expertise in medicine,” Wang said in an interview. “However, without a kind heart, a skilled doctor may cause harm to patie
