ABSTRACT
This paper present a microcontroller system for target controlled infusion according to pharmacodynamic parameters of intravenous anesthetics. It can control the depth of anesthesia by adjusting the level of plasma concentrations. The system has the advantages of high precision, extended function and easy operation. It has been now used in the clinical anesthesia.

Objective To summarize the regularity and and characteristics of response to interferon treatment for patients with chronic hepatitis B(CHB).Methods 150 cases of CHB were randomly divided into two groups:interferon therapy (observation group,n=90)and routine protecting liver(control group,n=60)By prospective researching programme,HBV markers,including liver function test were continous periodically detected simultaneously,HBV-DNA quantitative blot hybridization,HBV-DNA quantitative PCR determination were performed.Results The typical responsiveness curve of transaminase decreased rapidly,was accompanied with the use of interferon. HBV DNA turns negative earlier than HBeAg doses. In those patients who was response to interferon completely after interferon administration,the HBV DNA and HBeAg turning negative average time was 1 9 and 3 4 months respectively. The level of HBV DNA was continuons decreased in all patients treated with interferon. HBV DNA quantitative PCR provide more accuracy of viral copies in patient's peripheral blood than that in dot hybridization in interferon therapy.conclusions Interferon the treatment for patients with CHB is effectiveness.
