Non-alcoholic fatty liver disease: the problems we are facing.
OBJECTIVE
To review the current state of research in non-alcoholic fatty liver disease (NAFLD).


METHODS
Searching Medline (1994-2002) and Chinese Medical Journals Index (1998- 2002) for articles on NAFLD.


RESULTS
NAFLD is a new and challenging field with increasing recognition although its pathogenesis is poorly understood. "Two hits" hypothesis is still the leading theory guiding current research.


CONCLUSIONS
Genetic study is a promising way that might lead to breakthrough in NAFLD research. NAFLD study in China is at an initial stage and there is a long way to go.
