HKU launches probe after US journal retracts medical theses

An investigation is under way after a leading US medical journal retracted two studies on liver transplant by the University of Hong Kong (HKU) medical faculty.

HKU launched the inquiry after the American Journal of Transplantation (AJT) said it found discrepancies in the theses published online in 2006, Sing Tao Daily reports.

The discrepancies involved data taken from other sources that rendered the studies invalid, according to Intellectuals, a mainland media group.

“It appears that certain aspects of the figures were duplicated from other sources, rendering them scientifically invalid,” AJT said in a written reply to Intellectuals.

It said the discrepancies could not be rebutted or explained and raise concern about “scientific misconduct”.

AJT said it will release a retraction in its October issue.

The theses were written by dozens of staff in the Li Ka Shing Faculty of Medicine.

They included associate professor Dr. Man Kwan, the lead writer, Dr. Lo Chung-mau, head of surgery, and Dr. Fan Sheung-tat, now director of the liver surgery center of Hong Kong Sanatorium and Hospital.

Sing Tao said all three did not reply to its inquiries.

Former HKU professor Dr. Ronnie Poon said the theses were mainly the work of graduate students and that Lo and Fan merely gave their opinions.

Meanwhile, Intellectuals reported that 19 other theses from the HKU medical faculty are suspected to be forgeries.
