Dengue virus (DENV) is a re-emerging disease transmitted by the Aedes mosquitoes and has become a major public health problem in southern China. Currently, no antiviral drug or effective vaccine exist to control this disease. The chimeric DENV structural protein vaccine cannot elicit balanced levels of protective immunity to each of the four viral serotypes; therefore, non-structural protein components may be required to construct an effective DENV vaccine. The Dengue virus non-structural 1 (DENV NS1) protein plays a critical role in viral pathogenesis and protective immunity. Therefore, immunity to Dengue 1-4 NS1 subtypes may be crucial for the prevention of severe disease. This review attempts to provide an overview about the structure and function of DENV NS1.

Objective To analyze the hospitalization expenses of cancer patients covered with byitem payment and quota payment packages,and probe into the impacts on such expenses for the two payment packages.Methods Inpatient records of 600 cancer patients were sampled by random from the medical insurance databases of Zhengzhou and Fuzhou to learn their hospitalization expenses and impact factors.Results Under the by-item payment package,the expenses of urban workers’ medical insurance were found higher than those of urban residents' medical insurance,with a per capita expense of RMB 32747.70 ± 32035.01 and 23035.83 ± 22875.65 respectively.Under the quota payment package however,there were no significant differences between expenses of the two kinds of inpatients,with a per capita expense of RMB 66043.41±47562.09 and 66576.54±73417.29 respectively.Conclusion There are gaps of reimbursement level between the two basic insurance schemes,which may not disappear in a short time.Under the by-item payment package,the gap exists in the difference of perreimbursement amount; under the quota payment package,the gap is negligible between the two populations under different insurance schemes.It is recommended to make reasonable use of these different payment schemes to minimize the relative gaps in medical service accessibility caused by the difference in reimbursement level.

To study the influence of foreign plasmid DNA on spleen metabolism in immune-stimulated mice via the gastrointestinal tract. Mice were oral administered by pipette with 200?g of plasmid pcDNA3 and spleen were isolated at 4h and 18h after oral administration. Total RNA were extracted from spleen and spleen gene expression profile of Balb/c mice was analyzed by using Affymetrix oligonucleotide genechip after oral plasmid pcDNA3 administration. Functional cluster analysis was conducted by Genmapp and MAPPFinder software. By functional cluster analyzing the genes which were up-regulated more than twofolds, Genmapp results showed that plenty of metabolic pathway were induced in spleen after oral administration of plasmid pcDNA3. These metabolic process included purine metabolism, pyrimidine metabolism, protein synthesis, cholesterol synthesis, fatty acid synthesis, Glycolysis, TCA cycle and mitochondria oxidative phosphorylation pathway. The similar results also took place at 18h after oral administration. The result indicated that foreign plasmid DNA can modulate metabolism process in spleen of mice via the gastrointestinal tract, and may help understand the mechanism of action of foreign plasmid DNA uptaked via the gastrointestinal tract.

Objective To research the effects of bosentan in on unilateral ureteral obstruction (UUO) rats. Methods Wistar rats were randomly divided into three groups. UUO group was subjected to complete ligation of left ureter, sham operation group with sham operation was used as control. Bosenten group was subjected to complete ligation of left ureter and to stomach with bosentan suspension. Three groups were killed at 5,10,15,20 d. We examined renal pathological changes and the expressions of transforming growth factor-?1 (TGF-?1) in kidney of all rats using immunohistochemistry analisis method. The plasma and ureteral obstructive kidney urinary concentration of endothelin - 1 (ET - 1) was determined by radioimmunoassay. Results In Bos and UUO groups, the urinary concentration of ET - 1 increased substantially and the expression of TGF - ?1 were much higher than those in the S group. At the same time.tubulointerstitial fibrosis was present in the kidney of rats in Bos and UUO group. But the expression of TGF- ?1 and tubu-lointerstitial fibrosis in Bos group were lower than those of UUO group. Conclusion Bosentan can effectively amelirate tubulointerstitial fibrosis in rats with UUO by ET and TGF - ?1 machanism.
