Objective To investigate the immune response of mucosal immunization of new chitosan(CS) nanoparticles coating DNA vaccine. Methods The chitosan nanoparticles containing plasmid DNA encoding H. pylori lipoprotein Lpp20 gene were prepared using a complex coacervation method and then its speciality were analyzed. We then administered the naked plasmid DNA and chitosan-DNA nanoparticles to 6-week-old female BALB/c mice by intranasal or oral mucosal routes to observe the humoral and cellular immune responses. Results Naked plasmid pcDNA3.1 ( + )/Lpp20 and chitosan-pcDNA3. 1 ( + )/Lpp20 nanoparticles both induced effective immune response in mice through mucosal vaccination. Specific IgG and sIgA antibodies of chitosan-pcDNA3. 1 ( + )/Lpp20 nanoparticles groups were higher than that of naked pcDNA3.1 ( + )/Lpp20 group. The concentration of cytokines IFN-γ and IL-4 in cultural supernatant of T lymphocytes from chitosan-pcDNA3. 1 ( + )/Lpp20 nanoparticles immunized mice increased greatly than that of control groups. After stimulated by corresponding antigen, the stimulation index of intranasal or oral delivery of chitosan-pcDNA3. 1 ( + )/Lpp20 nanoparticles group was significantly higher than that of pcDNA3.1( + )/Lpp20 group, CS group and PBS control group. Moreover, systemic and mucosal immune responses in mice induced by intranasal immunization were stronger than that of oral immunization. Conclusion Chitosan nanoparticles enhanced the immune response of pcDNA3.1 ( + )/Lpp20 DNA vaccine by intranasal or oral administration in BALB/c mice. Compared to oral administration, intranasal delivery of chitosan-pcDNA3.1 ( + )/Lpp20 DNA nanoparticles could induce stronger cellular and humoral immune responses in BALB/c mice.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Objective To investigate whether the release of fibroblast growth factor-1 ( FGF-1 ) was changed after inhibition of S100A13 gene (small hairpin RNA, shRNA)and serum-deprivation in human thyroid cancer cells (TT cells ). Methods The S100A13-shRNA pENTRTM/U6 entry vector was transfected into TT cells. The expression of S100A13 mRNA and protein was detected by immunoflurescence, real-time RT-PCR, and Western blot. Then TT cells were treated with S100A13 gene inhibition and serum-deprivation. The changes in release of FGF-1 were detected by indirect immunoflurescence, RT-PCR, and ELISA. Results S100A13 shRNA transfected TT cells (S100A13 RNAi cells)had a reduction of S100A13 gene and protein expression by 80%.Indirect immunofluorescence indicated FGF-1 was mostly localized in the cytoplasm and nucleus of TT cells in primary culture. When serum-deprivation stress was given to TT cells, FGF-1 in cytoplasm almost disappeared in the cells at 6 h. RT-PCR indicated that when serum-deprivation stress was given to TT cells the mRNA of FGF-1 was reduced. ELISA showed that with inhibition of S100A13, the release of FGF-1 was reduced (P＜0.05).Conclusion S100A13-shRNA pENTRTM/U6 entry vector transfected TT cells may inhibit the expression of S100A13 and reduce the release of FGF-1.

Acidithiobacillus ferrooxidans are able to synthesize intra-cellular electron-dense magnetite,which makes possible that the bio-nano-magnetic particles could be obtained by cultivating Acidithiobacillus ferrooxidans. In order to isolate the strain which has the capacity to produce more magnetic particles, the solid-plate magnetophoresis method was firstly created. After isolation using the method, the rate of the cells which contain intra-cellular magnetic particles was increased from 30% to more than 90%, in addition, after isolation each cell possessed 2~5 magnetic particles which disperse in cells. The isolated cells are able to orient and migrate to the magnet in artificial magnetic field but could not orient swimming only under the geomagnetic field. Magnetosomes produced by Acidithiobacillus ferrooxidans were range from 40nm to 90 nm according to the results of TEM. Energy dispersive X-ray analysis indicated that extracted magnetic particles consisted of oxygen and iron. The results show that some Acidithiobacillus ferrooxidans cells have weak magnetotaxis and they could be able to be separated by solid-plate magnetophoresis method from others. With the development of this new isolation method, it is possible to do deeper research to generate a comprehensive description of the mechanism that how Acidithiobacillus ferrooxidans synthesize the magnetic particles.
