Objective To investigate expression of recombinant adenovirus(rAV) vector-mediated report gene in kidney, and to seek for the best passway of rAV vector-mediated gene transfer in vivo.Methods Thirty Sprague-Dawley(SD) rats were divided into 5 groups randomly. rAV-GFP(1013viral particales?L-1) was injected through different ways. 2, 7 and 14 d after injection, GFP expression in left kidney, right kidney, liver and lung was evaluated by fluorescence microscope and computer software. Results GFP gene expressed in kidey and reached peak 7 d after injection expression. Conclusion rAV vector-mediated report gene can be transducted in kidney. The rAV-mediated transgene expression in kidney is a potential strategy in the treatment of renal diseases.

Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) on the expression of glial fibrillary acidic protein (GFAP) and OX-42 in hippocampus and dentate gyrus in rats.Methods The rats were treated with 1 Hz, 100 mT TMS 10 min once a day for 14 days, and then the expression of GFAP and OX-42 in hippocampus and dentate gyrus were investigated by ABC technique of immunohistochemistry.Results Compared with the control group, there were no significant difference in the expression of GFAP and OX-42 between the two groups.Conclusion rTMS using our parameters does not cause brain injury in rats.

Objective:To investigate the association between polymorphisms of estrogen receptor ? (ER?) gene (rs3020444) and perimenopausal syndrome (PS) in patients with liver qi stagnation syndrome (LQSS). Metheds:The ER?T/C genotype in 100 patients of PS of LQSS type (PS-LQSS group),86 patients of PS of non-LSDS type (PS-non-LQSS group) and 100 healthy subjects (control) was determined by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) assay. Results:Partitions of ?2 method showed that the higher prevalence of ER?-TT genotypes was noted in PS-LQSS group (?2=8.307,P=0.004),and the higher prevalence of T alleles was noted in PS-LQSS group (?2=7.129,P=0.008). and Multinomial logistic-regression indicated that the odds ratios (OR) of the ER?-TT genotypes vs TC/CC for PS-LQSS was 2.222 (95%CI:1.172-4.744,P=0.015) after adjusting for common miscellaneous factors. Conclusions:It was suggested that ER?-TT genotypes was significantly associated with PS-LQSS,and ESR?-TT may be one of the genes that contribute to PS-LQSS.

OBJECTIVE:To provide references on how to avoid price war in Chinese drug retailing.METHODS:The status quo of Chinese drug retailing was analyzed,meanwhile the cause and effect of price war were discussed.RESULTS & CONCLUSION:The disadvantages of price war outweigh the advantages,which is sure to be replaced by services-based brand strategy.

Golgi phosphoprotein 3 (GOLPH3 )is closely related to the development and prognosis of cancer,such as non-small cell lung cancer,breast cancer,gastric cancer,esophageal cancer,colorectal cancer,etc.The mainly tumor pathogenisis related GOLPH3 includes modulating the response to DNA damage, vesicle trafficking,mTOR signaling pathway,mitochondrial functions,cytokinesis and Golgi vesicular malignant secretion,and then promoting cell proliferation,invasion and metastasis.GOLPH3 is expected to be a new tar-get for cancer therapy,which may become an important biomarker for the diagnosis,treatment and prognosis of cancer.

Objective To evaluate the training effect of Public health emergencies.Methods The testing materials from the training course on public health emergencies in longgang district of Shenzhen in 2009 were analyzed.Results Of all 162 students,98.2% considered the training course was completely important,97.3% students considered the training was very necessary,after training,80% students considered the master degree of related knowledge was improved,93.8% students considered the effect of training on the role of dealing with public health emergency training was very well or average.Conclusions Emergency response training for dealing with the public health emergencies is very effective and completely necessary.

Objective To investigate the effects of glucagon-like peptide-1(GLP-1)on the expression of apoptosis-related molecules including programmed cell death 5(PDCD-5)gene in pancreatic ? cells induced by proinflammatory cytokines.Methods Mouse islet ?-cell line NIT-1 was incubated for 24 h with cytokine mixture(Mix)in the absence or presence of GLP-1.The apoptotic cells were assayed by flow cytometry after stained with annexin V-FITC and propidium iodide(PI).The expressions of PDCD5,Fas,and caspase 3 were detected using reverse transcription-polymerase chain reaction(RT-PCR)and Western blot.Results The number of both annexin V single positive cells and annexin V/PI double positive cells significantly increased in the cells treated with 30 U/mL interleukin-1?(IL-1?)+ 100 U/mL interferon-?(IFN-?)+ 100 U/mL tumor necrosis factor-?(TNF-?).The expressions of PDCD5,Fas,and caspase 3 at both mRNA and protein levels were upregulated in the cells exposed to the cytokines.The above-mentioned effects of the cytokines were reversed by 10 nmol/L of GLP-1.Conclusion These data show that the proinflammatory cytokines cause pancreatic ? cell apoptosis via activation of PDCD5 signal pathway and that GLP-1 inhibits the upregulation of PDCD5 expression and the subsequent event of apoptosis induced by the cytokines.

Objective To study the expressions of S100B and glial fibrillary acidic protein(GFAP) in the central nervous system of Sprague-Dawley rats during postnatal development. Methods Twenty-four male SD rats were divided equally into four groups according to different postnatal times:7-day group,14-day group,21-day group and adult group.Immunohistochemistry was used to investigate the expressions of S100B protein and GFAP in the brain and the spinal cord. Results The amount and density of S100B positive astrocytes decreased significantly in frontal cortex,hippocampus,striatum,substantia nigra and spinal cord during postnatal development.It seemed that the second through the third week after birth was a critical period for these changes.The amount and density of GFAP positive AST increased gradually in the brain,but it was the opposite in the spinal cord.Double-labeled immunofluorescence of S100B and GFAP in hippocampus CA1 area showed that S100B positive stains were evenly distributed in the pyramidal,polymorphic and molecular layers from the seventh till the twenty first day after birth,but apparently decreased in each layer especially in the molecular layer in adult hippocampus while the immunoreactivities of GFAP increased.The proportion of double labeled cells also increased with the aging and more of them were found in the pyramidal and polymorphic layers.Conclusion Different patterns of the expressions of S100B and GFAP exist during postnatal development.It may reflect the different roles of these proteins on the glial cell development.And it may also indicate that the expressions of S100B and GFAP are regulated by different mechanisms during the course of development,which reflects the differentiation of subpopulations of astrocytes during ontogenesis.
