Objective To describe the effect of four-handed technique on the prevention of cross infection in department of stomatology. Methods Patients (300 cases) in department of stomatology were collected and randomized into the observation group (using four-handed technique) and the control group (not using four-handed technique) with 150 cases in each group from May 2003 to October 2004. One patient was served by one doctor and one nurse in the treatment process. Sterilization isolation system was strictly implemented in order to prevent cross infection. The control group received routine treatment. The incidence rate of infection was compared in the two groups. Results Ten patients (6.7%) were infected in the control group. Only 3 patients (2.0%) were infected in the observation group, which was lower than that of the control group (P<0.05). Conclusions Four-handed technique played an important role in the prevention of cross infection by blocking the iatrogenic infection propagation.

Primary hepatic carcinoma (HCC) is a common malignant tumor in China,which has the second mortality of all the malignant tumors.Establishing standard for high-risk population,selecting effective method for screening and formulating corrct regulation of screening play a vital role in discovering,diagnosing and treatment for hepatic carcinoma in earlier period,which helps to reduce the morality and save resource.At present,Oramatlc improvement ot biology and unageology,renovation of imaging equipments,economic devel-opment and people'S concerning about health provide strong insurance for screening of HCC,which makes itfeasible.
