Medical researcher endured pain to help others

Co-workers of renowned scientist Wang Yiping, who died in the spring after a long battle with Crohn's disease, are hailing his dedication in helping heart disease patients across the country while battling his own illness.

In 2005, a team led by the researcher produced his first new drug, which went on to benefit 15 million coronary heart disease and angina patients in China.

Wang, who aspired to invent drugs that are the first choice for doctors around the world, was found dead on April 11 at age 55 at his office beside his lab at the Shanghai Institute of Materia Medica, Chinese Academy of Sciences.
