BACKGROUND:Compared with smooth titanium, titania nanotubes cannot only induce mesenchymal stem cels osteogenic differentiation and promote bone integration, but also be used as drug nanocarriers. OBJECTIVE:To prepare dexamethasone-loaded titania nanotube system and to test its drug release characteristics. METHODS:Titania nanotubes were prepared by electrochemical anodic oxidation, and dexamethasone was dripped onto the prepared titania nanotubes. Subsequently layer by layer self-assembly technology was employed to fabricate gelatin/chitosan multilayered structure on the prepared samples. Scanning electron microscope and contact angle test were carried out during the process of building the gelatin/chitosan multilayered structure. The drug release was measured by a ultraviolet spectrophotometer. RESULTS AND CONCLUSION:Under the scanning electron microscopy, the fabricated titania nanotubes had integral structure with even tube size of about 70 nm and arranged regularly, and the nanotubes were completely covered and sealed by the gelatin/chitosan multilayered membrane. Contact angle test results showed that ever since the fifth layer, contact angles changed alternately and displayed a zigzag profile. Ultraviolet spectrophotometer test results showed that when cultured for 3 hours, the cumulative drug release was about 32.7% and demonstrated an initial burst folowed by sustained release. When cultured for 24 hours, the cumulative drug release about 52.3%. However, after cultured for 7 days, little drug release was detected. And there was about 8.0%-10.0% dexamethasone of initial loading preserved in nanotubes.

Objective:To study the influence of metformin and paclitaxel in the proliferation and apoptosis of human ovarian cancer SKOV3 cells in vitro, and to clarify the synergistic effect of metformin and paclitaxel. Methods:The ovarian cancer SKOV3 cells were divided into blank control group, different concentrations (0.01, 0.50, 1.00, 5.00, 10.00mmol·L-1) of metformin groups and combined treatment groups(metformin combined with paclitaxel with different concentrations).The inhibitory rates of proliferation of SKOV3 cells after treated with different concentrations of metformin were detected by MTT method.The apoptotic rates of SKOV3 cells after treated with different concentrations of metformin were measured by flow cytometry.The inhibitory rates of proliferation of SKOV3 cells after treated with metformin and paclitaxel were determined by MTT method.Results:The MTT results showed that the inhibitory rates of proliferation of SKOV3 cells in different concentrations of metformin groups were increased in concentration-and timedependent manner;there were significant differences compared with blank control group (P<0.05).The flow cytometry results showed that the apoptotic rates of SKOV3 cells in different concentrations of metformin groups were increased;compared with control group, with the increasing of concentrations of metformin, the apoptotic rates of SKOV3 cells in experimental groups 48 h after treatment were increased significantly (P<0.05);the percentages of SKOV3 cells in G0/G1 phase were decreased with the increasing of metformin concentrations(P<0.05) and the percentages of SKOV3 cells in G2/M phase were increased(P<0.05).The MTT results showed that the inhibitory rate of proliferation of SKOV3 cells in 1.00 mmol·L-1 metformin+paclitaxel group was higher than that in 0.50 mmol·L-1 metformin+paclitaxel group was higher than that in 0.50 mmol·L-1 metformin+paclitaxel group(P<0.05),and the inhibitory rates of proliferation of SKOV3 cells in combined treatment groups were higher than those in paclitaxel alone groups(P<0.05).Conclusion:Metformin inhibits the proliferation of ovarian cancer SKOV3 cells through the induction of apoptosis.Metformin can enhance the cell proliferation inhibition of paclitaxel on ovarian cancer SKOV3 cells.The combination of metformin and paclitaxel has a synergistic reaction on SKOV3 cells.

Objective To investigate CT image features of pleomorphic adenoma and adenolymphoma,and to improve the diagno-sis accuracy.Methods CT data of 1 3 cases of pleomorphic adenomas and 9 cases of adenolymphomas confirmed by pathology were retrospectively analyzed and compared.Results All 1 3 cases of pleomorphic adeonoma were solitary lesions,in which 1 1 cases were located in the non posterior inferior quadrant,and 1 1 cases showed persistent or delayed enhancement,with “slowly forward and slowly quit”enhancement performance.In all of the 9 cases of adenolymphoma,3 cases were multiple lesions.In total of 1 3 lesions, 9 lesions were located in the posterior inferior quadrant,and 9 lesions were significantly enhanced in the arterial phase and enhance-ment was decreased in the delayed phase,which showed “quickly forward and quickly quit”.Conclusion CT image features of pleo-morphic adenoma and adenolymphoma are different.Most of lesions can be diagnosed correctly before surgery by using image fea-tures with clinical information.
