This is an academic presentation about how to treat hepatitis B patients based on their lab work. The presentation does not contain any commercial or marketing information, and I do not think it would have violated any web.wenxuecity.com rules.
Unfortunately, the web link no longer works. Below are the presentation title and the presenter:
Treatment of HBV Infection
Emmet B. Keeffe, M.D.
Professor of Medicine
Chief of Hepatology
Stanford University Medical Center
You may be able to find the PPT or PDF file of his presentation with google search. Alternatively, you could contact your friends at Stanford University, and they may be able to get the presentation file directly from Dr. Keeffe.
Good luck.
