Truman - I'm not a doctor, but I've been to them (like that qualifies me to talk about anything...).
But I think talking to someone in medical research would be your best bet for the possibility of getting the word out. Maybe an organization like the National Institute of Health? I know you're in China...
They have contact information here:

There's also the World Health Organization, but they look pretty difficult to contact. You might want to start with a more localized group. Even a medical university might prove helpful -- I see (thanks, Google
that China is a strong participant in medical research.
A doctor or doctors may not be able to do anything with the information. It's far more likely that you'll get somewhere with researchers.
At any rate, it's really awesome that you've discovered an unknown cure, and I hope that you can get the word out about it!
ETA: Just had a thought -- you've probably discovered a natural cure, and not a drug, yes? If that's the case, you may want to contact holistic/naturopathic health organizations - two of them are the American Holistic Medical Association (
www.holisticmedicine.org) and the British Holistic Medical Association (
www.bhma.org). Also, whatever you do... don't contact Kevin Trudeau.
