Stringent approval procedure needed for medical research

REPORTS SAY THAT a team led by Professor Ren Xiaoping from Harbin Medical University successfully performed the first human head transplant on a corpse on Friday. Cjn.cn comments:

Ren and his colleague, Italian surgeon Sergio Canavero, have announced the operation was a success. However, just as Ren himself admitted in a later interview, there is no standard for the "success" of such an operation.

Besides, many doctors and medical professionals said they have only reconnected the severed blood vessels, tissues and nerves. There is no way to test whether signals or blood can pass through the re-connected channels.
