Objective To explore the functional expression and temporality of MDR1 gene in bone marrow of rabbits after autologous bone marrow transplantation with MDR1 transferred bone marrow mononuclear cells. Methods The supernatant of the amphotropic virus producer cell line PA317-HaMDR1/A was collected and concentrated to cocultivate with the bone marrow mononuclear cells of the rabbits. After large dose of chemotherapy with cyclophosphamide,the transferred cells were autotransplanted into the bone marrow. The integration,transfection rate and physiological function of MDR1 gene were tested by PCR,SP immunohistochemical method and daunorubicin (DNR) extrusion test respectively. Results After autologous bone marrow transplantation had been executed for 1-4 months,the integration of MDR1 gene in genome of bone marrow mononuclear cells was detected by PCR,and the expression rates of P-gp in cells tested by SP immunohistochemical method were 9.5%,8.5%,6.0% and 3.5% respectively. The physiological function of MDR1 gene in bone marrow cells was proved by DNR extrusion test. Conclusion After the autotransplantation with bone marrow mononuclear cells transferred by MDR1 gene,the MDR1 gene can implant into the bone marrow of rabbits and has expressed functionally for 4 months,which has provided a basis for further research on chemoprotection experiment of the MDR1 gene transferred into the bone marrow cells.

The clinical thoughts of interns have some features such as insufficiency of initiative and enthusiasm and the absence of systemic. It is necessary to develop their good habits of active and diligent thinking as well as comprehensive thinking ability. Clinical teaching rounds, small lectures,discussion of complicated cases and interactive teaching are the specific measures for our medical interns to improve their ability of clinical thoughts effectifally.

Objective To construct a recombinant adenovirus encoding ?-galactosidase gene(?-gal),which may be used to treat the lactose intolerance caused by lactase deficiency,with modified AdEasy system.Methods The sequence fragment of ?-gal was cloned into the shuttle plasmid pAdTrack-CMV,and the homo-logous recombination was completated with backbone plasmid pAdEasy1 in the E.coli BJ5183 to construct the recombinant adenoviral plasmid.The adenoviruses were packaged and amplified in the HEK293 cells mediated by liposome.The viral titre was measured by limiting dilution assay and the transfection efficiency was observed by X-gal histochemical staining.Results The recombinant adenovirus with ?-gal was constructed successfully and the viral titre was(2.5~4.0)?1011EFU/ml.More than 70% HEK293 cells were transfected when the MOI was 10.Moreover,more than 65% cells were blue after X-gal histochemical staining.Conclusion Recombinant adenovirus carrying ?-gal with high titre and efficient transfection is constructed successfully by AdEasy system,which supplies valuable experimental basis for the gene therapy to the lactose intolerance caused by lactase deficiency.
