Objective To construct DNA vaccine expressing Mycobacterium tuberculosis(Mtb) immunodominant antigen Ag85A and analyze its anti-tuberculosis T cell responses in BCG primed-mice after DNA vaccination boosting.Methods The coding gene of Ag85A mature fragment was amplified by PCR with H37Rv genomic DNA as template,and then cloned into the eukaryotic expression vector pVAX1 to construct Ag85A DNA vaccine.After purification,Ag85A DNA vaccine was injected intramuscularly twice in BCG primed-mice with BCG vaccination and DNA vaccination alone as control.Eight weeks post-vaccination,spleen lymphocytes were separated and were then used to analyze Mtb antigen specific effector T cell response and polyfuntional IFN-γ/TNF-α/IL-2 secreting CD4+ T cell frequencies and intensities,and CD8+T cell responses by IFN-γ ELISPOT assay and intracellular staining,respectively.Results Compared to BCG vaccinated-and DNA vaccinated-mice,Ag85A DNA boosting not only enhanced significantly BCG primed-mice IFN-γ+TNF-α+IL-2+,IFN-γ+ IL-2+,TNF-α+IL-2+ and IL-2+ CD4+ T cell frequencies and IL-2 secretion,but also improved significantly IFN-γ-secreting and IL-2-secreting CD8+ T cell frequencies.Condusion Ag85A DNA vaccine was constructed successfully and was demonstrated to enhance significantly BCG primed-mice Mtb antigen specific CD4+ and CD8+ T cell responses when boosting,which is beneficial to improve BCG immunogenicity and its waning immune protection against Mtb.

Objective To evaluate the possible association among serum folate,polymorphisms related reduced folate carrier gene (RFC-1) AS0G,methionine synthase reductase gene (MTRR) A66G,and cervical cancer,and to provide clues for the etiology of cervical cancer.Methods Based on a hospital-based case-control study,107 cases diagnosed as cervical cancer pathematologically and 107 controls with hysteromyoma,were selected by frequency,matched with age and habitation.Serum folate concentration was detected by RIA and polymorphism RFC-1 A80G and MTRR A66G was examed by RFLP-PCR.Results Serum folate concentration in patient group [(1.86±0.60) ng/rml] was significantly lower than that in control group [(2.30 ± 1.14) ng/ml],and risk of cervical cancer increased with the decreased serum folate levels (x2trend =12.57,P =0.001).Risks to catch cervical cancer for women with RFC-1 80 GG were 2.42 times (95 ％ CI 1.01-5.81) as much as for those with RFC-1 80 AA,and 1.65 times (95 ％ CI 0.77-3.53) for those with RFC-1 80 AA and RFC-1 80 AG,risks to catch cervical cancer for women with MTRR 66 GG were 1.35 times (95 ％ CI 0.40-4.56) as much as for those with MTRR 66 AA and 1.26 times (95 ％ CI 0.38-4.16) for those with RFC-1 80 AA and RFC-1 80 AG.Conclusion Serum folate deficiency to a certain degree can increase the risk of cervical cancer.RFC-1 A80G mutation may be a risk factor for cervical cancer and homozygous (GG) gene may increase the susceptibility of cervical cancer.MTRR A66G gene mutation may have nothing to do with cervical cancer.

Objective: To investigate the protective effect of human lipoxin A4 (LXA4) on N2a cell damage induced by β-amyloid protein 25-35 (Aβ25-35) and the underlying mechanism. Methods: Aβ25-35 was used to treat N2a cells to establish Alzheimer's disease (AD) cell injury model. Meanwhile, LXA4 was added to the experimental group at different concentrations (50, 100 and 200 nmol·L-1 ). MTT assay was used to detect the activity of N2a cells. The apoptosis was detected by Hoechst 33258-PI staining, the expression of P62 and TRAF6 mRNA was detected by RT-PCR, and the expression of P62 and TRAF6 protein was detected by Western blot. Results: Compared with that of the model group, the cell survival rate of LXA4 protective group (50,100 and 200 nmol·L-1 ) increased (P <0. 01) and the apoptosis of N2a cells induced by Aβ25-35 was reduced by LXA4 (100 and 200 nmol·L-1 ) . Compared with that of the model group, the expression of P62-mRNA and protein-P62 of N2a cells treated with Aβ25-35 increased (P <0. 05 or P <0. 01) and the expression of TRAF6-mRNA and protein-TRAF6 of N2a cells treated with Aβ25-35 were reduced (P <0. 05 or P <0. 01). Conclusion: LXA4 has protective effect on N2a cell damage induced by Aβ25-35 , and its mechanism may be related to the up-regulation of P62 gene and down-regulation of TRAF6 gene.

Objective In order to evaluate that whether Pluronic P85 coated poly(butylcyanoacrylate) nanoparti-cles was able to deliver antiepileptic drug phenytoin into the brain va bypassing mesial temporal lobe epilepsy (MTLE)-induced Pgp in a rat model of MTLE. Methods The rat model of MTLE, induced by li-pilocarpine, was divided in-to two groups (6 for nanoparticle drug group and 7 for PHT drug group). Immunohistochemistry assay was performed to detect Pgp expression at the hippocampus. Nanoparticles were prepared by interfacial polymerization method. Dialysate samples of brain were collected at 30, 60, 120, 180, 240 and 300 min after drug administration by microdialysis tech-nology. Samples were analyzed by high performance liquid chromatography (HPLC). Results The area under the curve (AUC) ratio of brain/plasma in Nanoparticle drug group was 0.370.10 which was significantly higher compared with 0.190.06 in conventional PHT drug group (P<0.05). The Pgp immunopositive area, as assessed by analysis of labeled surface area, was higher in the DG, CA3 and CA1 sector in the hippocampus of MTLE rats when compared to the normal rats. Conclusions Pluronic P85 coated PBCA nanoparticles can significantly deliver PHT into brain via bypassing MTLE-induced Pgp in a rat model of MTLE.

Objective To study the effects of erythropoietin (rhEPO) in high glucose induced proliferation and apopto?sis of human kidney proximal tubular epithelial (HK-2) cells, and the possible mechanism thereof. Methods HK-2 cells cultured in vitro were divided into several groups randomly:blank control group, high glucose group, mannitol group, rhEPO control group, different concentrations of rhEPO treatment groups (5, 10, 20 U/mL) and Rho kinase group. The reverse tran?scription polymerase chain reaction (RT-PCR) was used to evaluate the mRNA levels of RhoA and ROCK after 24 hours. Tetrazolium salt method (MTT) was used to determine the cell proliferation. Cell apoptosis was detected by flow cytometry. Results Compared with blank control group the expression levels of RhoA and ROCK1 mRNA were significantly in?creased in high glucose group (P < 0.05). RhoA, ROCK1 mRNA expressions significantly decreased in rhEPO group than those of high glucose group (P<0.05). There was a positive correlation between the expression levels of RhoA mRNA and ROCK1 mRNA in high glucose group and rhEPO group. MTT method showed that rhEPO significantly promoted the prolifer?ation of HK-2 cells (P<0.05). Flow cytometry analysis showed that high glucose induced apoptosis in HK-2 cells, which was significantly inhibited in rhEPO group and Rho kinase group as compared to that of high glucose group in a concentra?tion dependent manner (P<0.05). Conclusion rhEPO can promote HK-2 cell proliferation and inhibit apoptosis, which may be related to RhoA/ROCK signaling pathway.
