In order to improve the expression level of segment of GABAA receptor a1 subunit in E. coli, growth conditions of the recombatant, which influence the final yield of protein expression, including growth medium, inoculation ratio, temperature, pH, rotation speed, inducing time and concentration of IPTG and so on, were studied in shaking flasks. The results indicated that, with 3% inoculation ratio, cultured 3.5 hours at 37℃, and then induced 5 hours by IPTG at 32℃, the yield of GABAA receptor protein was 95mg/L and the biomass was 3.25 g/ L. In contrast, using a 16 L stirred fermentor instead of shaking flasks, the highest level of the protein expression, 136mg/L with 4.95g/L of biomass, was achieved after fermenting 5.5 hours.

Abstract Objective: To study the relationshiop between the HBV pre-c mutant and the clinical the, the host immunity. Methods: Mu-tation specific PCR(msPCR) was employed for detecting pre-c mutant in 92 cases with HBV-DNA positive;T subpopulations were determinedby APAAP immune-bridge assay; the cytokines (TNF?、 sIL-2R ) levels by ELISA. Results: 57 cases had Pre-c mutant, the rate was ahaut 62 %;pre-c mutant existed popularly in different e systems status, mainly in anti-HBe(+) serum. The reat increased with the deterioration of liverfunction, and was highest in fulminant hepatitis, the percentage of CD4 T lymphocyte and the ratio of CD4/CD8 were aignificantly lower in mu-tational group than in wild group,but CD8 T lymphocyte was obviously higher, the quantity of sera TNF? and sIL-2R in mutational group wereobviously higher than in wild group, both groups were obviously higher than control group. Conclusion:PreC 1896 mutant existed popularly inpatients with HBV infection. There were more serious disturbance in host immunity in mutant group. The mutant may be associated with the pre-ssare of host immune system.The mutant type virus could provoke host immunity resulting in severe liver damage.

The specific ScFv gene against botulinum neurotoxin A (BoNTa)was cloned into pPIC9k. Positive integrators were screened by increasing the dose of G418 in culture and expressed in Pichia pastoris GS115. As a result, engineered recombinant clone were obtained. 26 kD product of interest was seen easily in SDS-PAGE. Expression of human ScFv got the highest level 15% of total secreted proteins during 72~84 h after 1% methanol inducing. Purification of ScFv was finished by two steps: gel filter and ion exchange. Competing ELISA showed that recombinant ScFv could compete with antiserum to specific bind BoNTa.

Objective To investigate the relapse risk assessment for patients with acute promyelocytic leukemia(APL)through testing PML-RAR? fusion gene by real-time quantitative polymerase chain reaction(RQ-PCR).Methods Relative copies of PML-RAR? fusion gene were measured in 25 patients with APL in phases of first diagnosis,complete remission(CR)and relapse.The minimal residual disease(MRD)situations were also monitored in 6 of the 25 patients.Results Different PML-RAR? fusion gene expression levels were observed in patient groups of different phases of the disease.(P
