Objective To study the inhibition of vibramycin on the expression of matrix metalloproteinase 2 (MMP 2) and the invasiveness of androgen independent prostatic carcinoma cell line PC 3 in vitro. Methods Immunohistochemistry stain and transwell chamber were used to investigate the expression of MMP 2 in different concentration of vibramycin treated PC 3 cells and the invasive ability of different concentration of vibramycin treated PC 3 cell. Results The positive rate of MMP 2 in PC 3 cells was decreased at a concentration of 5 mg/L of vibramycin and decreased dramatically at the concentration of 10 mg/L.The cells moved through the membrane was (82.0?4.6)/field in the control group,while decreased to (26.1?3.6)?(7.2?2.2) and (3.3?0.7)/field in 5?10 and 20 mg/L vibramycin treated PC 3 cell respectively. Conclusions Vibramycin can inhibit the invasiveness and metastasis of PC 3 cells, the mechanism of which is related to the inhibition of MMP 2 in PC 3 cell.

Objective To validate the gross tumor volume (GTV) delineation in head and neck cancer based on magnetic resonance imaging (MRI) or computed tomography (CT) by cross-sectional autopsy,and to provide a basis for clinical evaluation of the two imaging methods.Methods Ten New Zealand rabbits were selected for transplantation of VX2 carcinoma cells,and a head and neck cancer model was successfully established in six rabbits.Each rabbit was fixed and received MRI scan and CT scan in the same body position.Then,they were sacrificed and fixed in gelatin solution (-70℃) for 72 h; all cryopreserved rabbits underwent cross-sectional autopsy using a jig saw,with the same position and sectional thickness as in MRI scan and CT scan,and cross-sectional autopsy images were obtained using a digital single-lens reflex camera.GTVs were separately delineated based on CT,MRI,and cross-sectional autopsy images.The GTVMRI,GTVCT,GTVSA,and volume difference ratios (VDRs) were calculated;two-way classification ANOVA and paired t-test were used for difference analyses.Results The mean values of GTVMRI,GTVCT,and GTVSA were 8.20 ± 2.56,8.40 ± 2.20,and 8.11 ± 2.88 cm3,respectively,without significant differences among them (F =0.06,P =0.943).The mean values of VDRMRI-SA and VDRCT-SA were 0.180 ± 0.060 and 0.309 ± 0.091,respectively,with a significant difference between them (t =7.49,P =0.001).Conclusion The GTV delineation based on MRI is more accurate than that based on CT in head and neck cancer.

Aim To investigate the effects of Guaveno-ic acid (GA)on proliferation,insulin synthesis and secretion in INS-1 cells and their possible mechanism. Methods INS-1 βcells were cultured in vitro.Control group,medium group,model group,drug groups and positive group were set.INS-1 cells were treated with GA (0.3,1 ,3,1 0,30 nmol·L -1 )for 48 h.The cell proliferation was tested by MTT assay.Acid-alco-hol was used to extract the insulin in the cells and the amount of insulin synthesis of INS-1 cells was tested by RIA.5.6,1 6.7 mmol·L -1 glucose was used to chal-lenge INS-1 cells for 1 h to the insulin secretion model (BIS and GSIS)was tested,and the insulin secretion of INS-1 cells was tested via RIA.The mRNA expres-sion of insulin gene,PDX-1 and MafA was tested by q-PCR.Results Compared with medium group,GA could promote the proliferation of INS-1 cells signifi-cantly (P <0.01 )and promote the synthesis of insulin in INS-1 cells significantly (P <0.01 ).GA(0.3 ~30 nmol· L -1 )could promote the BIS,GSIS of INS-1 cells significantly (P <0.05 or P <0.01 ).GA (3,30 nmol·L -1 )could up-regulate the mRNA expression of insulin gene,PDX-1 ,MafA in INS-1 cells signifi-cantly (P <0.01 ).Conclusions GA could signifi-cantly improve the proliferation of INS-1 cells and pro-mote the insulin synthesis and secretion of INS-1 cells, which may be associated with up-regulation of insulin gene,PDX-1 ,MafA mRNA expression.

Thymopentin (TP5) and bursopentin (BP5) are both immunopotentiators. To explore whether the TP5-BP5 fusion peptide (TBP5) has adjuvant activity or not, we cloned the TBP5 gene and confirmed that the TBP5 gene in a recombinant prokaryotic expression plasmid was successfully expressed in Escherichia coli BL21. TBP5 significantly promoted the proliferation of thymic and splenic lymphocytes of mice. The potential adjuvant activity of the TBP5 was examined in mice by coinjecting TBP5 and H9N2 avian influenza virus (AIV) inactivated vaccine. HI antibody titers, HA antibodies and cytokines levels (IL-4 and IFN-γ) were determined. We found that TBP5 markedly elevated serum HI titers and HA antibody levels, induced the secretion of both IL-4 and IFN-γ cytokines. Furthermore, virus challenge experiments confirmed that TBP5 contributed to inhibition replication of the virus [H9N2 AIV (A/chicken/Jiangsu/NJ07/05)] from mouse lungs. Altogether, these findings suggest that TBP5 may be an effective adjuvant for avian vaccine and that this study provides a reference for further research on new vaccine adjuvants.
