Objective To investigate the clinical significance of YMDD mutation during Lamivudine therapy on chronic hepatitis B.Methods Fluorometric analysis PCR, ELISA were used to estimate the YMDD mutation, HBVDNA quantative level and HBeAg for HBV of 72 cases with chronic hepatitis B before therapy (0 month), and after Lamivudine therapy for 9,12,18 months.Results The YMDD mutation was not observed in these cases before Lamivudine therapy. The mutation was found in 8 cases (11.1%), 17 cases (23.6%) and 28 cases (38.9%) at 9, 12, 18 month for therapy. The YMDD mutation rate rose with the therapy time lasting (P<0.05). Moreover, the YmDD mutation rate in the patients with HBVDNA quantity higher than 108 copies/ml was significantly higher than that in the patients with HBVDNA quantity lower than 108 copies/ml (P<0.005). The YMDD variation rate in patients with HBeAg positive and in patients with HBeAg negative showed no significant difference (P>0.05). The HBeAg negative conversion rate was significantly higher in non-mutation group than that in mutation group (P<0.05).Conclusion The serum virus quantity may be regard as an early estimate indication of the development of YMDD mutation during Lamivudine therapy.

In light of the IT development in hospitals, the authors point out the necessity of setting up the post of CIO and clarify the role of the CIO in the construction and management of the hospital information system. They argue that the CIO should not only be in charge of the technology support of the information network platform, but also exercise the function of managing hospital information. While hospitals ought to attach importance to the development and application of information systems and the role of the CIO, the CIO, on his part, ought to try to enhance his competence and become a versatile talent expert at various disciplines like medicine, management and the computer.

AIM: To study the effect of Lomerizine on the activity of P-glycorprotein (P-gp) in primary cultured rat brain microvessel endothelial cells (RBMECs). METHODS: Flow cytometry was used to study the efflux of rhodamine123 (Rh123) and expression of P-gp in RBMECs. RT-PCR was used to measure the expression in mRNA level of mdr1 gene in RBMECs. Transwell model was used to detect the influence of Lomerizine on the transport of Rh123 through RBMECs monolayer. RESULTS: Lomerizine inhibited the efflux of Rh123 in RBMECs. No changes of P-gp and mdr1 gene mRNA expression were detected in RBMECs after the treatment with 30 μmol·L-1 Lomerizine for 72 h. In the study of Transwell model, Lomerizine increased significantly the transport of Rh123 through RBMECs monolayer from upper compartments to lower compartments, and inhibited obviously the transport in reverse direction. CONCLUTION: The effect of Lomerizine on the activity of P-gp was mainly via its direct inhibitory effect on the function of P-gp in RBMECs and the transport of P-gp substrates in BBB may be affected by lomerizine.
