Objective:To investigate the antitumor efficiency of the special cytotoxic T lymphocytes(CTLs) activated by dendritic cells(DCs) pulsed with K-ras (12-Val) antigen.Methods:DCs was generated from PBMC in the presence of granuloceyte/macrophage-colony stimulating factor(GM-CSF),interleukin-4(IL-4)in vitro.DCs were differently sensitized with K-ras mutant pancreatic cancer cell line,K-ras(12-Val) mutant peptide,K-ras(12-Val) mutant peptide with the surface of cationic nanoparticle.Cell surface markers on DCs was measured by flow cytometry.The activation of CTL induced by DCs was detected by ~3H- thymidine incorporation test.The killing effects of CTL to pancreatic cancer was detected by ~(125)I-UdR release test. Production of IL-12 and IFN-γ by DCs and PBMC was detected by ELISA.Results:Compared with DCs pulsed with K-ras(12-Val) mutant peptide and K-ras (12-Val) mutant peptide with the surface of cationic nanoparticle,DCs pulsed with whole tumor antigen could better induce CTLs killing activity(P＜0.05).The DCs with K-ras(12-Val) mutant peptide and K-ras mutant peptide with the surface of cationic nanoparticle could produce specific CTL killing activity aganist pancreatic cancer cell line Patu8988(K-ras+)(P＜0.05),but not SW1990(K-ras-)(P＞0.05). K-ras (12-Val) mutant peptide with the surface of cationic nanoparticle at lower concentrations can be effectively presenting on the surface of DCs than only K-ras (12-Val) mutant peptide.Conclusion:K-ras (12-Val) mutant peptide with cationic carrier can be effectively presenting and expression of DCs and induce CTL specific killing activity aganist pancreatic cancer cell lines with K-ras (12-Val) mutant peptide.

Objective:To investigate the immunogenicity of pORF5 plasmid protein,and further to screen and identify its im-munodominant domian.Methods: 10 different fragments of pORF5 gene including full length were amplified from the DNA of Chlamydia trachomatis serovar D by PCR and cloned into appropriate site of pGEX-6p vector to construct recombinant vectors after digested with BamHⅠand NotⅠrestriction endonucleases.After identification by PCR and sequencing,the recombinant plasmids were transformed into XL1 Blue E.coli to express the GST fusion proteins.ELISA and Western blot were carried out to identify the immunogenicity and immunoreaction of pORF5 plasmid protein.10 different fragments were reacted with sera from patients urogenitally infected with Chlamydia trachomatis, mouse polyclonal antibodies and mouse monoclonal antibodies of pORF5 plasmid protein with ELISA method.Results: pORF5 plasmid protein displayed strong immunogenicity and could induce a strong antibody response in human.The reactivity of human antibodies almost completely disappeared,when the native structure of pORF5 plasmid protein was de-stroyed.F6 that only lacked the N-terminal 66 amino acids was recognized by antibodies in ELISA as strongly as the whole pORF5 plasmid protein was.However,no other fragments were significantly recognized although there was a minimal reactivity of F2 and F3 with antibodies.Conclusion:pORF5 plasmid protein was an immunodominant antigen containing conformation-dependent epitope,and the C-terminal three quarters of pORF5 amino acid sequence was required for maintaining its immune dominance and conformation.The significance of the above findings lay a foundation for the further study on pORF5 protein function and vaccine development.

Objective To apply robotic surgery of early ovarian malignancy tumors clinically and evaluate its feasibility in management for early ovarian cancer. Methods Using the da Vinci robotic surgical system, seven patients with early ovarian malignancy tumors (stage Ⅰ) underwent robotic surgery from April 2012 to September 2013. The average age was 45.7 years. Robotic surgeries approaches contained salpingo-oophorectomy,para-aortic lymphadenectomy, pelvic lymphadenectomy, omentectomy and appendectomy. Perioperative and follow-up clinical data were recorded. Results All robotic surgeries were successfully completed without the conversion to laparotomy. The mean operative time was 225 minutes (100-330 minutes). The average estimated blood loss was 171 ml (20-600 ml). No patients received blood transfusions. No intraoperative and postoperative complications were observed. The average number of pelvic lymph node dissected were 18.3 (11-34). The average number of para-aortic lymph node dissected were 3.7 (3-4). The mean follow-up time was 26.0 months after surgery (20-36 months). Currently, all patients had no tumor recurrence and survived. Conclusion Robotic surgery is feasible as a novel alternative approach in the treatment of early ovarian malignancy tumors.

Objective To explore the efficacy and safety of fondaparinux combined with tirofiban in patients with high risk unstable angina (UA) undergoing complex percutaneous coronary intervention (PCI).Methods A total of 389 patients were enrolled and randomized into two groups receiving either fondaparinux with tirofiban or enoxaparin with tirofiban.Bleeding,thrombosis and main adverse cardiovascular events (MACE) were compared between the two groups during hospitalization,at week 2 and week 4 after discharge.Results No severe bleeding was observed during hospitalization in the both groups,while lower rate of mild and minor bleeding was shown in the fondaparinux group (0 vs 1.5％ and 18.2％ vs 34.5％,P =0.04 and P ＜0.001 respectively).No difference was found between the two groups in the rate of MACE during hospitalization,at week 2 and week 4 weeks after discharge.The rates of death,recurrent myocardial infarction,refractory myocardial ischemia and target vessel revascularization were 0.5％ vs 1.0％,0.5％ vs 1.0％,1.6％ vs 1.0％ and 2.1％ vs 1.5％ during hospitalization;0 vs0,1.0％ vs 0.5％,1.0％ vs 1.5％,0.5％ vs 1.0％ at week2 after discharge; 0.5％ vs0.5％,0.5％ vs0.5％,2.6％ vs 2.0％,0 vs 0.5％ at week 4 after discharge (all P values ＞ 0.05).Conclusion The combination therapy of fondaparinux and tirofiban is of good safety and efficacy in high risk UA patients undergoing complex PCI.

Objective To evaluate inhibitory effect of Chlamydia trachomatis plasmid-encoded protein pORF5 on HeLa cell apoptosis induced by tumor necrosis factor-alpha(TNF-α). Methods The recombinant lentiviral expression vector containing pORF5 gene and helper plasmids were co-transfected into 293T cells to prepare the recombinant lentivirus. Then, the lentivirus particles were collected and concentrated, and used to infect HeLa cells. Flow cytometric screening identified stable pORF5-expressing HeLa (pORF5-HeLa) cells. Meanwhile, the empty plasmid was transfected into HeLa cells to prepare control HeLa cells. The two cell lines were both divided into two subgroups to be treated with 20μg/L TNF-αand fresh culture medium respectively for 6 hours. Then, Hoechst 33258 staining was performed to observe morphological changes of apoptotic cells, flow cytometry to detect cell apoptosis, real-time PCR to measure the mRNA expression of Caspase3, Bax and Bcl-2, and Western blot analysis to determine the protein expression of Bax and Bcl-2. Results After 6-hour treatment with TNF-α, Hoechst 33258 staining showed variable degrees of karyopyknosis and karyorrhexis, and highly-refractive blue apoptotic bodies in the pORF5-HeLa cells and control HeLa cells. The pORF5-HeLa cells and control HeLa cells both showed significantly higher apoptosis rate in the treated subgroup than in the untreated subgroup (pORF5-HeLa cells:35.5%± 4.5%vs. 9.5%± 1.5%, t=13.53, P<0.01;control HeLa cells:63.6%± 5.8%vs. 7.9%± 0.9%, t=32.36, P<0.01). Compared with treated control HeLa cells, treated pORF5-HeLa cells showed significant decreases in mRNA expression of Bax(72.8%)and Caspase 3(84.5%)(t = 35.29, 42.25, respectively, both P < 0.01), as well as in Bax protein expression(t = 17.58,P < 0.01), but significant increases in Bcl-2 mRNA and protein(6.8 times)expression(t = 87.12, 18.93, respectively, both P <0.01). Conclusion pORF5 plasmid protein can inhibit TNF-α-induced HeLa cell apoptosis likely by increasing the expression of anti-apoptotic protein bcl-2 and decreasing the expression of pro-apoptotic proteins Caspase-3 and Bax.
