Objective To investigate the influence of lentivirus mediated short hairpin RNA(shRNA)target to human papilloma virus(HPV)16 E6 on invasive ability of cervical cancer Caski cells.Methods Lentivirus was produced after shRNA target to human papilloma virus(HPV)16 E6 and to nonsense was cloned to lentivirus work vector.Infection ratio was assessed by assay of EGFP positive cells of Caski.Total mRNA of E6 was determined by RT-PCR after Caski cells were infected by lentivirus.The change of E6 protein expression was analyzed by Western blot.The invasive ability of Caski cells was assayed employing Transwell.Results The optimal MOI (Multiplicity of infection)of lentivirus to Caski was 2.5.Total mRNA and protein of E6 were decreased (by 70%and 63%)in interfering group compared with control group.The invasive ability of Caski cells also reduced after infected by lentivirus.Conclusion shRNA mediated by lentivirus can inhibit expression of HPV16 E6 and invasive ability of cervical cancer cells.

Objective:To evaluate the efficacy and safety of capecitabine or S-1 combined with oxaliplatin or cisplatin in the treat-ment of advanced gastric cancer. Methods:Six databases including Cochrane Library, Pubmed, Embase, CNKI, VIP and WanFang were retrieved. Randomized controlled trials ( RCT) in the treatment of advanced gastric cancer were involved for the quality assess-ment and Meta-analysis. Results:A total of 14 RCT involving 1 051 patients were included. There were no significant differences in the total effective rate, complete remission rate and partial remission rate between the two groups(P>0. 05). In the safety evaluation, the incidence of hand-foot syndrome was higher in capecitabine-based regimens than that in S-1-based regimens[RR=2. 59,95%CI (1. 61,4. 17),P<0. 000 1], while the incidence of stomatitis was lower in capecitabine-based regimens[RR=0. 64,95%CI(0. 50, 0. 82),P=0. 000 4]. The other adverse reactions such as nausea and vomiting, diarrhea,neuropathy,dysfunction of liver and kidney, anemia, leukopenia, neutropenia and thrombocytopenia exhibited no significant differences between the two groups(P>0. 05). Con-clusion:Capecitabine combined with oxaliplatin or cisplatin has similar efficacy with S-1 combined with oxaliplatin or cisplatin in the treatment of advanced gastric cancer, and the incidence of hand-foot syndrome is higher in capecitabine-based regimens and the inci-dence of stomatitis is higher in S-1-based regimens.

BACKGROUND: A novel biodegradable Mg-Zn alloy is designed which the density and the Young's modulus are proximal to human bone. At the same time, it depletes the toxicity of aluminium and rare earth element in commercial magnesium alloys. OBJECTIVE: To observe the effect of Mg-Zn alloy (Mg-6%Zn) on the integrin βi expression of preosteoblasts MC3T3-E1. DESIGN, TIME AND SETTING: A contrast study was performed at the Central Laboratory of the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University between March and May 2008. MATERIALS: The Mg-6% Zn was prepared by School of Materials Science and Engineering of Shanghai Jiao Tong University, which the density was 1.82 g/cm~3 and the Young's modulus was nearly 44 GPa. Poly-L-lactic acid (PLLA) was used as the controls. MC3T3-E1 cells were provided by Chinese Academy of Science Type Culture Collection. METHODS: The cell attachment was observed after cultured with Mg-Zn and PLLA at 2, 24 and 48 hours under scanning electron microscope; the integrin β1 mRNA expression of MC3T3-E1 cultured with Mg-Zn and PLLA was estimated by real-time fluorescent quantitative polymerase chain reaction (real-time PCR) at days 1, 3, 6, 9,12 and 15 after culture. MAIN OUTCOME MEASURES: The MC3T3-E1 cells attachment on the material surface and the integrin β1 mRNA expression. RESULTS: MC3T3-E1 cell adhesion was better on the Mg-Zn alloy surfaces than on the PLLA surface; The integrin (31 mRNA of osteoblasts on Mg-Zn kept on expressing during experiment and increased with time (P < 0.01), but there was no significantly difference between the two groups at the same time (P > 0.05). CONCLUSION: MC3T3-E1 cell adhesion is better on the Mg-Zn alloy surfaces than on the PLLA surface, but it is not mediated by inducing the integrin p1 mRNA expression.

Objective To investigate the degradation of dicalcium phosphate dehydrate-coated Mg-Zn alloy in vivo and bone formation. Methods Left femoral condyles were drilled in 72 New Zealand rabbits, and were randomly divided into experiment group (n=24, implanted with dicalcium phosphate dehydrate-coated Mg-Zn alloy rods), Mg-Zn alloy control group (n=24, implanted with Mg-Zn alloy rods) and poly-L-lactide acid rod group (n=24, implanted with poly-L-lactide acid rods). Serum concentrations of Mg~(2+) were examined 1 d pre-operation, and 1 d, 1 week, 2 weeks, 5 weeks and 10 weeks post-operation in experiment group and Mg-Zn alloy control group. Operation sites were examined by X-rays at 3, 6, 12 and 18 weeks post-operation. After X-ray examination at each time point, 6 rabbits in each group were sacrificed, and subjected to histopathological observation of live and kidney tissues by HE staining. Tissues from condyles of femur were observed by HE staining and 2, 4, 6-trinitrophenol rosein staining, and mineral apposition rate of bone was calculated. Results There was no significant difference in the concentrations of serum Mg~(2+) at each time point between Mg-Zn alloy control group and experiment group (P>0.05). X-ray examination revealed gas emerged near the implants 3 weeks after surgery in Mg-Zn alloy control group. However, there was no obvious histological abnormality in liver and kidney tissues. The mineral apposition rate was higher and the degradation of material was lower in experiment group than those in the other two groups. Conclusion Dicalcium phosphate dehydrate-coated Mg-Zn alloy has a favourable biocompatibility, and degrades more slowly in vivo.
