AIM To explore the effects and mechanism of cobra venom serum on the proliferation in HL60 cells. METHODS Established the HL60 cells as a target to study the growth feature by the action of cobra venom serum.The agarose gel electrophoresis and flow cytometry analysis were used to demonstrate apoptosis. RESULTS Compared with the control group, the cells were inhibited significantly by the action of cobra venom serum.A characteristic DNA "ladder" was detected by using agarose gel electrophoresis. By flow cytometry analysis,it was proved that most apoptosis of HL60 cells occurred when cultured with cobra venom serum. CONCLUSION Cobra venom serum inhibited the HL60 cells in vitro , which was related to apoptosis. This may introduce a new way to the treatment of leukemia.

Objective To up-regulate the expression of Glil gene in periodontal ligament stem cells ( PDLSCs) and to explore the effect of Glil gene on PDLSCs proliferation and osteogenesis differentiation by establishing Glil gene adenovirus vectors. Methods Subcloned Glil to viral backbone vector Adtrack-CMV and transfered the established vector to 293T cells, which was to acquire the virus particles. Trans-fected aim cells,namely PDLSCs,with these virus. Detected its effect on PDLSCs proliferation with CCK-8 assay, and detected the expression of Glil and the bone-related markers ALP and Runx2 through Western blot. Results An adenovirus vector, which were over expressed Glil gene, was successfully constructed and transfected to PDLSCs. Compared with the empty vector group and normal group, the over expressed one had a much slower proliferation rate in CCK-8 assay (P=0. 003). Western blot showed that ALP and Runx2 can be overexpressing os-teogenic differentiated after PDLSCs successfully transfected with the Glil gene. Conclusion Over expressing Glil gene would lead to a much slower proliferation rate in the PDLSCs and an increase of the bone-related markers. It is concluded that Glil can enhance the osteogenic dif-ferentiation capacity in PDLSCs.

Objective To explore the bioeffects of canine myocardium under microbubble destruction via diversity of ultrasonic intension, in order to optimize ultrasonic intension for experiments. Methods Nine mongrel dogs were randomly divided into 3 groups. Ultrasound (1 MHz) in diversity of different intension (0.5 W/cm~2, 1.0 W/cm~2, 2.0 W/cm~2) was applied to expose canine myocardium after intravenous injection microbubbles of 2.0 ml. All the dogs were killed after being exposed for 5 min. The myocardium was harvested for HE staining and observed with transmission electron microscope for the tissue microstructures. Results The myocardium of hyperemia, disfiguration and necrosis wer observed in all groups. Myocardial edema but not hemorrhage appeared with 0.5 W/cm~2 , mild myocardial hemorrhage and slight inflammatory cell infiltration happened with 1.0 W/cm~2, whereas obvious hemorrhage and certain degree of inflammatory cell infiltration occurred with intension of 2.0 W/cm~2. With the augmentation of ultrasonic intension, myocardium trend to aggravate. Conclusion Ultrasound of diversity intension can induce different bioeffects of canine myocardium. Ultrasound mediated microbubble destruction with the intensity of 1.0-2.0 W/cm~2 can provoke a certain degree of inflammatory reaction with mild myocardial damage.

In this study, nattokinase gene was amplified by PCR using bacillus subtilis chromosomal DNA as template and cloned into expressed vector pBV220. After transforming recombinant plasmid into E.coli HB101, the recombinant strain was yielded. It was proved that expression products was secretive and expression protein was 12% of total cell protein by SDS-PAGE. Optimum culture time and inducing time was determined as 6h and 5h respectively. The plasmid stability studies showed that recombinant plasmid has excellent segregational stability but the structural stability was not good in the host cell.
