Objective To express human-mouse chimeric antibody against anthrax protective anti-gen and to analyze its biological activities. Methods A new mammalian bipromoter expression vector was constructed with dihydrofolate reduetase(DHFR) gene as the selection and complication marker. First, the light and heavy chain variable region gene of the monoclonal antibody 5E1 were cloned by RT-PCR, at the same time the human IgG1 heavy chain constant region gene and kappa type constant region gene were cloned. Next, the human-mouse chimeric antibody genes were synthesized by fusion PCR. Then, the hu-man-mouse chimeric antibody gene were inserted into MCS of pSecTag and B1 to construct pSecTag-5E1L and B1-5E1H, respectively. Finally, heavy chain expression cassette excised from the B1-5E1H with Bgl Ⅱ/BamH Ⅰ was further cloned into the Bgl Ⅱ site of the pSecTag-5E1L to construct pSecTag-5E1. Plasmid pSecTag-5E1 was transfected into CHO(dhfr) engineering cells and high production cell clones that were screened by enhancing MTX concentration. After collecting medium and purifying chimeric antibody with af-finity chromatogram, purified chimeric antibody was analyzed by SDS-PAGE, Western blot. Results A sta-ble and high production cell line was acquired at MTX concentration 5×10~(-8) mol/L. Conclusion The hu-man-mouse chimeric antibodies were successfully expressed in CHO cells.

OBJECTIVETo compare the efficacy of bicyclol tablets on patients infected with hepatitis B virus between genotype B and C.
METHODS70 patients with chronic viral hepatitis B were selected. The patients divide into two groups: HBV genotypes B (26 cases) and HBV genotypes C (other 44 cases). All patients received bicyclol tablets orally 150 mg daily (50mg, tid, po) for 24 weeks. The efficacy were observed after 12 weeks and 24 weeks.
RESULTSAfter treatment for 24 weeks, the serum aminotransferase were decreased obviously, and HBV DNA levels turn to be negative with 19.2 percent (genotype B group) and 15.9 percent (genotype C group), respectively. The difference was not statistically significant between HBV genotype B and C.
CONCLUSIONBicyclol not only has hepatoprotective activity but also inhibited virus replication in patients infected with HBV. The difference of the response to bicyclol therapy between HBV genotypes B and C was not statistically significant.

OBJECTIVETo examine the changes of expressions of orexin A, orexin receptor-1 (OX1R), prepro-orexin (Prepro-OX) mRNA, OX1R mRNA and ob-R of hypothalamus in rats with chronic renal failure (CRF).
METHODSSixty-two male Wister rats weighing 200-250 g were divided into three groups, including group 1 (normal, n = 5), group 2 (sham-operated, n = 25) and group 3 (CRF, n = 32). Hypothalamus orexin A was assayed by radioimmunoassay. Serum leptin was assayed by enzyme linked immunosorbent assay. The expression of Prepro-OX mRNA and OX1R mRNA of hypothalamus were measured by reverse transcription polymerase chain reaction, and expression of orexin A, OX1R and ob-R by immunohistochemistry. Automatic biochemical analyzer was used to measure the serum creatinine.
RESULTSHypothalamus orexin A levels were negatively correlated (r = -0.63, P < 0.001) with serum leptin levels in the rats. The expression of hypothalamus Prepro-OX mRNA in CRF rats was significantly lower than that of sham-operation at week 12 (P < 0.01). Hypothalamus Prepro-OX mRNA levels were negatively correlated (r = -0.81, P < 0.001) with the levels of serum leptin and serum creatinine (r = -0.68, P < 0.05) in the rats at week 12. The expression of hypothalamus OX1R mRNA in CRF rats was lower than that of sham-operation at week 12 (P > 0.05). Specific immunoreactivity for orexin A was present in perikeryon of the hypothalamus neuron. Specific OX1R-like immunoreactivity was observed in some nerve fibres. Specific immunoreactivity for ob-R was present in membranes of the hypothalamus neuron. Hypothalamus neurons of orexin A-like specific immunoreactivity in CRF rats were significantly fewer than those in shamoperated rats at week 8. Hypothalamus neurons of OX1R-like specific immunoreactivity in CRF rats were similar to those in sham-operated rat at week 8. Hypothalamus neurons of ob-R-like specific immunoreactivity in CRF rats were significantly more than those in sham-operated rats at week 8.
CONCLUSIONSThe lower hypothalamus orexin A levels may be induced by high serum leptin level in CRF rats. The lower expression of hypothalamus Prepro-OX mRNA in CRF rats may be one of the main causes inducing lower hypothalamus orexin A. The expression of OX1R in hypothalamus neurons is somewhat reduced and the expression of ob-R in hypothalamus neurons is somewhat raised in CRF rats. These remain to be studied further.

OBJECTIVETo study the influence of the reference values for semen analysis proposed in the 5th edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen on the indication spectrum for intrauterine insemination (IUI).
METHODSWe retrospectively analyzed the clinical data of 111 cycles of IUI by the reference values for semen analysis in the 4th edition of the WHO Laboratory Manual (group A) and 84 cycles by the 5th edition (group B). We recorded and compared the percentages of various indications for IUI between the two groups.
RESULTSThe complications for IUI in groups A and B were as follows: asthenospermia (87.4% [97/111] vs 55.9% [47/84], P < 0.05), oligospermia (0 vs 0), teratospermia (51.4% [57/111] vs 35.7% [30/84]) , abnormal liquefaction (0.9% [1/111] vs O) , sexual dysfunction and genital malformation (0 vs 3.6% [3/84] , immune infertility (0.9% [ 1/111] vs O), and unexplained infertility (3.6% [4/111] vs 2. 4% [2/84 ] ). There were no significant differences between the two groups in the percentages of all the indications except that of asthenospermia.
CONCLUSIONThe reference values for semen analysis proposed in the 5th edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen have an evident influence on the indication spectrum for IUI by largely reducing the cases of IUI for male factors, prolonging the cycles of some patients, causing excessive diagnosis and treatment for females, and increasing their mental and economic burdens.

AIMTo provide proof for Evidence-based Medicine as well quality control, our laboratory detected the thrombin activity on various body position.
METHODSBy autogenous contrast and cross matched survey, 105 volunteers divided into 3 season patches of winter, spring and summer, blood samples were drawn from the same part in both standing and lying position. Both samples and the quality control were detected to investigate the effect of the body position to thrombin activity's changing. The data were analyzed by SPSS 10.0.
RESULTSTaking the lying's data as baseline, the average changing on all those the "5" index was 7.07% and the highest changing reached 9.33%. This kind changing had great significant differences (P < 0.01). According to the t value, sequences ranged: FIB > TT > PT > INR > APTT. FIB, TT and APTT's values slowly raised, adversely PT and INR slowly went down. While sitting for 15 min after lying, these indices returned to 95.2% of the original value in sitting position in addition. Season, age and device had no relationship with body position.
CONCLUSIONChanging body position can result in obvious physiological variation of thrombin activity.
