Objective:To analyze the immune response in mice after immunization with vaccine of rAd5F35-SIVenvT in combination with rMVA-SIVenvT to evaluate the efficacy of different immunization strategies.Methods:Two recombinant viruses were identified in vitro by PCR and Western blot. The BALB/c mice were immunized with homologous and heterologous immune strategies. The numbers of splenic lymphocytes secreting IFN-γ were measured by ELISPOT assay, meanwhile SIV gp120 antibody titer were measured by ELISA assay. Results:SIVenvT protein was expressed effectively by rAd5F35-SIVenvT and rMVA-SIVenvT in HEK293 cells. The specific immune response reached its peak at 4-week post first immunization, then decreased. SIV Env specific cellular immune response and SIV gp120 specific antibody could be detected at 4-16 weeks post first immunization. The specific cellular response was significant stronger in heterologous immunization group than homologous group at 4 week and 16 week. Furthermore, heterologous immunization induced significant higher titer of SIV gp120 antibody at 4 week than homologous group.Conclusions:Specific immune response induced by rAd5F35-SIVenvT in combination with rMVA-SIVenvT was stronger than homologous vector immunization. The results provided references for further study in nonhuman primates.

Objective: To observe the curative effect of compound carraghenates cream(Titanoreine) combined with vitamin B₆ in the treatment of hand-foot syndrome caused by capecitabine(Xeloda). Methods: From December 2015 to December 2017, 97 cases of middle and advanced colorectal cancer in the First People's Hospital of Yongkang were selected.All patients were treated by chemotherapy regimens of capecitabine as priority after operation, but later hand-foot syndrome appeared and they were randomly divided into treatment group (48 cases) and control group (49 cases) according to the digital table.In control group, only vitamin B₆ 30 mg was taken orally, three times daily; while in treatment group, vitamin B₆(30 mg) combined with compound carraghenate cream (1g) were taken orally, three times daily after hand-foot syndrome occurred.The improvement, total efficiency, pain score during the treatment process (the first, fifth, ninth day after treatment), adverse reactions were observed before and after treatment in two groups. Results: After treatment, the hand-foot syndrome in the treatment group and the control group was improved, the difference was statistically significant (treatment group: Z=6.477, P=0.000; control group: Z=4.700, P=0.000). The total effective rate of the treatment group was 87.5%(42/48), which was significantly higher than 65.3%(32/49) of the control group (χ²=6.603, P=0.010). The pain score on the ist day after treatment had no statistically significant differences between the two group[treatment group: (2.88±1.82)points, control group: (3.14±1.74)points, t=0.741, P=0.461] The pain scores on 5th and 9th day after treatment in the treatment group were (2.29±1.52)points, (1.23±1.80)points, respectively, which were lower than those in the control group [(2.94±1.38)points, (2.14±1.90)points](t=2.200, 2.430, P=0.030, 0.017). There were no statistically significant differences between the two groups in general conditions and the incidence of adverse reactions after drugs uses(all P<0.05). Conclusion Compound carraghenate cream combined with vitamin B₆ has significant effect in the treatment of hand-foot syndrome caused by capecitabine, which can improve hand-foot syndrome better and help tumor patients to finish the chemotherapy successfully.

Objective: To assess the association of single nucleotide polymorphisms (SNPs) in SLCO1B3 gene with prognosis of breast cancer (BC) patients treated with neoadjuvant chemotherapy of TA regimen (taxane and antharcycline drugs). Methods: 439 female BC patients were recruited and treated with neoadjuvant chemotherapy of TA regimen. A blood sample (2 ml) of peripheral blood was collected from each patient before chemotherapy. Tagging SNPs (tag-SNPs) were selected. We investigated the association of tag-SNPs with prognosis, by Sequenom Mass ARRAY system platform, characterizing tag-SNPs. The hazard ratio (HR) and 95% confidence interval (CI) for progression or death were calculated by multivariable-adjusted Cox regression model. Results: Seven tag-SNPs (rs11045689, rs200104106, rs3764006, rs3834935, rs4149117, rs7305323 and rs73241801) were selected for study. Compared with individuals carrying the rs11045689 GG genotype, individuals carrying rs11045689 AA genotype performed worse PFS and OS, with the HR (95% CI) for progression being 1.39 (1.11~1.75) and the HR (95% CI) for death being 1.38 (1.04~1.83). Compared with individuals carrying the rs73241801 CC genotype, individuals carrying rs73241801 TT genotype performed better OS (P=0.041), with the HR (95% CI) for death being 0.65 (0.44~0.94). The number of risk allele was significantly associated with PFS (P=0.012) and OS (P=0.017) of BC patients by accumulation analysis. Compared with individuals carrying one or less than one risk allele, individuals carrying four risk alleles performed worse PFS and OS, with the HR (95% CI) for progression being 1.37 (1.09~1.72) and the HR (95% CI) for death being 1.36 (1.02~1.81). Conclusion The variations of rs11045689 and rs73241801 in SLCO1B3 gene were significantly associated with prognosis of BC patients treated with neoadjuvant chemotherapy of TA regimen, which might serve as biomarkers for predicting prognosis of BC patients treated with neoadjuvant chemotherapy.

Therapeutic HIV vaccine was considered as a hopeful curative method for AIDS patients. However, there is still no suitable HIV animal model for vaccine study since the difference in the immune system between human and animals. To evaluate the therapeutic effect of combined immunization strategy with multiple vector vaccines in macaque models. Plasmid DNA, recombinant Ad5 and MVA vaccines which expressing SIV gag and env genes were constructed. Sequential and repeated immune strategy were applied to immunize mice with these three vaccines. Cellular immune responses in mice immunized with these three vaccines were measured by ELISPOT test in vitro and CTL assay in vivo. The results were analyzed and compared with different antigen combination, order of vaccines and intervals to choose a suitable immunization strategy for macaque immunization in future. It indicated that strong SIV-Gag/Env-specific cellular immune responses were induced by these three vector vaccines. It laid a foundation for evaluating the therapeutic effect of combined immunization strategy with multiple vector vaccines in SIV infected macaque models.
