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.

Objectives To investigate the clinical and pathological characters , treatment of patients with Angioimmunoblastic T cell lymphoma(AITL). Methods From 1997 to 2004, 14 patients with AITL were reviewed retrospectively in our hospital. Results The most common symptoms at the presentation included general lymphadenopathy. 9 patients had fever. 3 patients had autoimmune hemolytic anemia.The histopathologic characteristics of AITL was generalized as:the damage of normal structure of lymphonodus,the proliferation of immunoblastic cell and arborescent supervascularization. All immunophenotyping were T cell type.14 patients were with ProMACE-CytaBOM regimen.The overall response rate was 57% and CR 3 cases, PR 5 cases. Median survival times was 25 months. 2-year survival was 60 %. Conclusions The most cases with AITL runs an aggressive course.The disease may progress rapidly and have unfavorable prognosis. Therefore further studies are repuired to improve the outcome.

CD4 +CD25 +Foxp3 +regulatory T cells(Tregs)are essential for tumor immunosuppressive mi-croenvironment and secrete some inhibitory cytokines IL -10,IL-35,TGF-β1 and FGL2 which are key media-tors of Treg immunosuppressive function .Tregs have been shown to be important contributors to the tumor escape immunosurveillance and play a critical role in the induction of suppression to CD 4 +T,CD8 +T and NK cell,and suppression of specific anti -tumor immunity .Further research of the role of Tregs in tumor immunosuppressive microenvironment is important to understand malignant tumor pathogenetic and immunological therapeutics .In ad-dition,Tregs and inhibitory cytokines become more critical for clinical applications ,prognosis evaluation and ther-apies.

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.
