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.

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 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.

BACKGROUND:The gut microbiota in our intestine performs numerous useful functions and has a major impact on the host’s health. Recently some studies have revealed that the gut microbiota cannot only control intestinal activity but also affect bone metabolism by regulating the immune system. OBJECTIVE:To review the new research development in the effects of gut microbiota on bone metabolism. METHODS: We retrieved the PubMed database using “gut microbiota, immune system, bone metabolism, osteoporosis” as keywords. A total of 46 articles were included which were related to gut microbiota, immune system and bone metabolism. For the articles in the same field, those published recently or in authorized journals were selected. RESULTS AND CONCLUSION:Gut microbiota-osteoporosis research wil bridge the gaps between bone physiology, gastroenterology, immunology, and microbiology.In vivo experiments in the germ-free mice and human body have found that the gut microbiota has important effects on bone metabolism, and the intervention of antibiotics, probiotics and prebiotics has further confirmed the effects of gut microbiota on bone mass. The gut microbiota has more obvious effects on bone mass in the adolescent and post-menopause periods.

Objective To observe the incidence,clinical types,and prognosis of pulmonary involvement in children with systemic lupus erythematosus(SLE),and to probe the relationship between the relative factors.Methods The clinical data of 61 children with SLE,who treated in Children's Hospital of Shanghai from Jan.2006 to Dec.2011 were analyzed retrospectively.The lung manifestations of the patients were classified according to their clinical symptoms and signs,and lung imaging examination (chest X-ray and CT).Other data of the SLE patients with lung injury or without lung injury were collected,including the course of the disease,activity index [SLE disease activity index (SLEDAI) scoring 0-4 was divided into no activity,5-9 was divided into low activity,10-14 was divided into moderate activity,and more than 15 as severe activity],blood sedimentation,the values of serum complement and the positive rate of dsDNA in autoantibody,and a comparison was made and statistical analysis was performed.Results Pulmonary injury occurred in 17 cases with an incidence rate of 27.9％ (17/61 cases),and the average course of the disease was (8.76 ± 6.96) months.The clinical manifestations of 17 cases included fever,cough,dyspnea,hypoxemia,chest pain,lower breath sound,and lung rale,which were not non-specificity.According to imageological examination,in 17 cases there were 2 cases with pulmonary hypertension (the incidence rate was 11.8％),4 cases with acute lupus pneumonitis (the incidence rate was 23.5％),6 cases with interstitial pneumonia (the incidence rate was 35.3％),7 cases with lesion of pleura (the incidence rate was 41.2％),10 cases with pulmonary infection (the incidence rate was 58.8％).There were no statistical differences between patients with and without lung injury(infectious and non-infectious)in the course,the values of serumn complement,the positive rate of dsDNA and activity index.Lung lesions of the 17 patients recovered quickly after early diagnosis and active treatment.Conclusions Pulmonary manifestation in children with SLE is not uncommon,and it can happen at any stage of the disease,not just on the stage of lupus activity,but it usually indicates disease was not controlled.Pulmonary manifestation of SLE in children involve many parts of lung,including pulmonary parenchyma,interstitial,blood vessels,pleura,etc.Early diagnosis and active treatment can improve the short-term prognosis of lung injury with lupus,and long-term outcome remains to be observed.
