OBJECTIVESBased on the immunologic character of Pichia pastoris yeast, a new therapeutic vaccine, whole recombinant yeast, was used to explore a new way to activate cell-mediated anti-viral immunity.

METHODSThe recombinant plasmids, pPIC9K/S and PIC9K/hsp(1-370)-S, were constructed by inserting the gene encoding HBsAg, HSP70 (1-370) -HBsAg into vector pPIC9K and then the recombinants were transfected into Pichia pastoris yeast,GS115, respectively. Then that recombinant yeast immunized BALB/C mice were detected for humoral and cellular immunity to HBsAg.

RESULTSRecombinant yeast successfully activated the humoral immunity to HBsAg in mice, but failed to activate the cellular immunity.

CONCLUSIONThe whole recombinant yeast can be used as vaccine, but need further study for optimal way of immunization.

OBJECTIVETo evaluate the academic level and the popularity of the Chinese Journal of Hepatology in China in 2005.

METHODSWe used bibliometrics to analyze statistically the original articles of the Chinese Journal of Hepatology cited by Chinese periodicals included in the Wanfang Data in 2005.

RESULTS(1) 699 published papers in the journal in 2005 were cited 1673 times and 44 of them were cited 720 times in total. (2) The papers published in the Chinese Journal of Hepatology were cited by journals in China starting from 1993 through 2005. Of all the cited articles, 1.49% of them were cited in the same year as they were published. (3) Non-specific rate of the Chinese Journal of Hepatology was 96.17%, and self-cite rate was 3.83%. (4) Papers published in the Chinese Journal of Hepatology were cited by 400 Chinese periodicals, 99 of them are journals included in the Chinese Science Citation Database, and 110 of them are Chinese core periodicals.

CONCLUSIONThe Chinese Journal of Hepatology is one of the high level academic Chinese periodicals. This journal reflects the progress in research on liver diseases in China.

OBJECTIVETo investigate the feasibility of detecting cyclin D1 protein expression and t(11;14) chromosomal translocation in paraffin-embedded tissues and its diagnostic and differential diagnostic significance for mantle cell lymphoma (MCL).

METHODSParaffin-embedded samples of 36 cases of MCL and a control group of 71 cases of small B-cell lymphomas were retrieved from archive materials. Immunohistochemical staining for cyclin D1 and semi-nested PCR for t(11;14) were detected in all samples. House-keeping gene beta-actin was used to detect the quality of DNA.

RESULTS(1) Cyclin D1 was expressed in 26 of the 36 MCL (72.2%). There was no cyclin D1 expression in the control group. (2) beta-actin DNA was detected in 101 of the 107 tumor cases (94.4%). t(11;14) was detected in 22 of the 36 MCL. Translocation was not found in control group. The positive rate for t(11;14) was 64.7% in MCL after exclusion of 2 cases which were negative for both t(11;14) and beta-actin. (3) 29 cases were positive for cyclin D1 and/or t(11;14), the positive rate reached 80.5%.

CONCLUSIONThe combined detection of cyclin D1 and t(11;14) in paraffin-embedded tissues is found to be a specific and feasible method for diagnosis and differential diagnosis of mantle cell lymphoma.

OBJECTIVETo evaluate the efficacy and safety of five-year trail of entecavir for chronic hepatitis B patients failed with lamivudine therapy in the Chongqing area.

METHODS32 patients failed with lamivudine therapy were enrolled in this study. In the double-blind phase, patients were randomly divided into entecavir 1.0 mg/d group (n = 28) and placebo group(n = 4) for 12 weeks. In the open-lable phase, patients received ETV 1.0 mg/d for 240 weeks. HBV DNA level, liver function, HBV serology were observed.

RESULTSThe mean reduction in HBV DNA level at week 12 was 4.05 log10 copies/ml in ETV group, and 0.08 log10 copies/ml in placebo group (P less than 0.05). The mean of HBV DNA level after 240 weeks of ETV treatment was decreased to 2.58 log10 copies/ml. The proportion of patients with HBV DNA less than 3 log10 copies/ml was 0, 6.25%, 15.6% , 50%, and 57.14% at 0, 8, 24, 96 and 240 weeks respectivfely. There were 2 patients with HBsAg seroconversion and 4 patients with HBeAg seroconversion at the end of the study. The ALT level returned to normal at week 12 and remained normal throughout the following 240 weeks. One patient had a severe adverse event during the trail.

CONCLUSIONEntecavir is effective and safe for the chronic hepatitis B patients failed with lamivudine therapy.
