Description of intervention(s) / exposure
we give adefovir 10mg oral tablet, once a day to patients in treatment group.Overall duration of antivirus treatment is according to the guideline of chronic hepatitis B. The indicatons to stop antivirus treatment are as follows:1.to the patients with HBeAg(+), they should take medicine for 6-12 months after HBeAg(+) becoming HBeAg(-) and then can stop the antivirus treatment;2.to the patients with HBeAg(-), when HBV-DNA is undetectable for three times with a interval of 6 months,they can choose to stop treatment;3.to cirrhosis patients, we recommend taking antivirus treatment for whole life.

the rate of HBV reactivation after liver resection and the change of liver function. The patients will check serum HBV-DNA every 3 months(in our hospital) and liver function every month(in the local hospital). If the HBV-DNA increases 10 times or become detectable, it means virus reactivation.

Summary
Brief summary
The purpose of our study is to see whether anti-virus drugs can improve the prognosis of liver cancer and reduce the viral reactivity. We supposed that adefovir can reduce the tumor recurrence and viral reactivity, prolong the overall survival of patients.
