This text involved with a pre-enrichment medium for the simultaneous recovery of Salmonella spp.,Escherichia coli and Staphylococcus aureus.This medium is named buffered saline broth(BSB),which contains peptone 10g,beef exact 3g,disodium hydrogen phosphate 9g,potassium dihydrogen phosphate 1.5g,additive 50g,deionized water 1 000mL,pH7.2.1cfu per one milliliter of Salmonella spp.,Escherichia coli and Staphylococcus aureus in saline were stimutaneously added to 97 mL of BSB,buffered peptone water,lactose broth,nutrient broth,Escherichia coli broth,rappaport-vassiliadis enrichment broth,7.5% sodium chloride enrichment medium,respectively,and incubated for 18h at 37℃.The results showed BSB was the best enrichment medium,in which Salmonella spp.,Escherichia coli and Staphylococcus aureus multiplied at nearly same speed,and reached at 10~6 、10~6 、10~7 cfu/mL,respectively.Multiplex PCR produced specific amplicons of expected sizes,284bp for Salmonella spp.invA gene,622bp for Escherichia coli phoA gene,484bp for Staphylococcus aureus nuc gene.In contrast,the three bacteria couldn't multiply harmoniously in the other six media.So BSB might be considered as the medium,which could enrich above mentioned three bacteria.

Biodegradable nano/microparticles of poly(D, L-lactide-co-glycolide) (PLGA) is a novel non-viral gene vector, which has many advantages, such as safety, non-immunogenicity, easy of large-scale preparation and well load-capability. Therefore, more and more attentions and researches have been paid on its application. Especially, PLGA has shown enormous potential application value and space in the field of plasmid DNA (pDNA) delivery system. On the basis of the current situation of PLGA nano/microparticles for pDNA delivery, this paper focused on summarizing the current preparation approaches and surface modified methods of PLGA particle, furthermore showing its application in gene therapy and genetic vaccine delivery. These showed that PLGA nano/microparticles have extensive prospect in the development of controlled gene delivery system.

The phosphorylation is one of most common protein post-translational modifications. The protein phosphorylation plays important roles in the life through the reversible process of phosphorylation and dephosphorylation by kinases and phosphatases. Systematical analysis of the phosphorylation state of proteins would greatly help to reveal the mystery of the life. Recently, with the development of mass spectrometer, bioinformatics sortwares and enrichment methods of phosphopeptides, phosphorylation stduy of orgnism proteins by mass spectrometer has become mature gradually. Liver is one of the most important metabolic and immune organs. In-depth study of protein phosphorylation in liver is of great importance to reveal its function. And booming phosphoproteomics has been applied into the study of liver, which has deepened the knowledge of molecular mechnism of its physiology and pathology states. Here, we review the recent progress on the research and development of phosphoproteomics and their application in liver proteomics study.

Objective: To observe the effect on Tangzu Heji on diabetic foot rat with blood stasis syndrome and to investigate the mechanism in it. Methods: Combination of streptozocin injection and reduction of ambient temperature was used to duplicate diabetic foot rat with blood stasis syndrome. 60 Male SD rats were randomly divided into 6 groups as normal control group, the low temperature control group, diabetic foot group (model group), three groups of Tangzu Heji treatment with high, medium and low dose respectively. In the first three groups the rats were given normal saline, and in the latter three treatment groups the model rats were given Tangzu Heji as 60gkg, 30g/kg, 15g/kg weight, respectively. After two weeks of treatment, the changes of the weight, water intake, blood glucose, blood rheology, acral gangrene symptoms, Choroid blood vessels of the sublingual and ear, serum vascular endothelial growth factor changes were observed. Results: After two weeks of treatment with Tangzu Heji, compared with the model group, a marked increase in body weight, decrease of water intake were happened to the rats in treatment groups. Erythrocyte aggregation index in the low-dose treatment group decreased significantly (P

Objective: To explore the way of innovation and development of the pattern and means in nursing management in military hospital.Methods:Through various innovative practice from the following aspects,such as nursing service philosophy and measures for soldiers,the methods of nursing management and the elite-cultivating,nursing security management,which demonstrates the availability of innovation and development of the pattern and means in nursing management in military hospital.Results:The satisfactory rate of nursing service reached up to 99% in the examination of serving for soldiers of the whole army.The instruments which are manufactured for battle-scarred wounds and injuries use the flat of the Wound Nursing Centre,have reached the stage of clinical trial,we have completed five items of serial nursing research.The control rate of nursing quality of the whole hospital increased from 93.12% in 2003 to 98.9% in 2006,the satisfactory ratio of serious in-patient increased from 90.2% in 2003 to 96.7% in 2005.The ratio of health education achieves 100%.The satisfactory ratio of in-patient was 98.4% in September 2005,compared with 89.3% in February 2004.Conclusion:Only innovation can make nursing management develop and improve in military hospital.

Objective To investigate the relationship among the proliferation of CD4+T cells, the intracellular levels of interleukin-10 (IL-10) and transforming growth factor-?1(TGF-?1), and allergic bronchial asthma. Methods Dermatophagoides farinae antigen were prepared as allergen. Twenty-five patients with asthma and 15 healthy individuals were enrolled and divided into blank control group, allergen group and self control group, respectively, after venous blood sample collection. The proliferation of CD4+T cells and the distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 were measuredby flow cytometry (FCM). Results The distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 could hardly be detected in the peripheral blood samples of the blank controls of the patients with asthma and healthy ones. In the allergen group of the healthy individuals, the peripheral blood CD4+T cells were significantly proliferated, and the proportions of CD4+T cells andCD4+/IL-10+ cells were much higher than the self control group, while there was no significantly increase in the proportions of CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 subgroups. In the allergen group of those with asthma, the proportions of peripheral blood CD4+, CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 cells were not found significantly increased compared with those self controls. After being activated by allergen, the proportion of peripheral blood CD4+/IL-10+ cells was significantly lower in the patients with asthma than the healthy individuals(P
