     BEIJING-Pharmacologist Tu Youyou has become the first scientist on the mainland to win America's

respected Lasker Award for her discovery of a new approach to malaria (疟疾) treatment.

     The 81yearold was presented with the medical prize by the Albert and Mary Lasker Foundation on

September 23, 2011 in New York.

     Tu, a scientist at the China Academy of Chinese Medical Sciences in Beijing, was praised by the jury (评判委员会) for her "drug therapy (治疗) for malaria that has saved millions of lives across the globe,

especially in the developing world," according to a statement on the foundation's website.

     In early 1969, Tu was appointed head of a government project that aimed to eradicate(消灭) malaria, and it was then that she began applying modern techniques with Chinese traditional medicine to find drug

therapy for malaria.

     After detecting (检测) 380 extracts (提取物) made from 2,000 candidate recipes, Tu and her

colleagues obtained a pure substance called "Qinghaosu", which became known as artemisinin in 1972.

An artemisininbased drug combination is now the standard regimen (养生法) for malaria, and the World

Health Organization lists artemisinin and related agents in its catalog of "Essential Medicines", said a

statement from the foundation.

     The Lasker Awards are given annually to people who have made major advances in the understanding, diagnosis, treatment, cure and prevention of human diseases since 1945.
