Policy background and stakeholder theory were elaborated.It could be concluded that the key stakeholders of the policy were residents,training hospitals,healthcare administrators,primary healthcare institutions and patients of such institutions.Through analysis of these stakeholders,effects on the interests of all parties were investigated and strategies to improve feasibility of the policy were put forward.Two key points were suggested for such policy goals.First,top-level policies should be designed and be effectively implemented.Second,conversion of the residents from permanent hospital employees to “contractors”or“ freelancers”.

Objective To analyze the feasibility of the policy that “Residents service or employment at primary care institutions after standardized training”.Methods Analyzing the feasibility of this policy by using questionnaire survey and in-depth interview.Results Constituent ratios of overall feasibility were 58.3％ (532/912)and 66.1％(603/912)for specialist and general practitioner respectively; percentage of feasibility of in-depth interview was 46.7％ (7/15).Conclusion The policy has feasibility,if government formulates and implements perfect complement policies effectively,and makes this policy to be impassable stage to resident.

Objective To stuay the serum levels of sCD40L,hsCRP,ICAM-1 and VCAM-1,and the expression of CD40L of the CD4+T cells in patients withacute coronary syndrome(ACS),and to explore the relationship between CD40L and inflammatory factors and the effects of CD40/CD40L on ACS.Method Thirty-two coronary heart disease patients without history of other discernible systemic disease and medicine of steroids or immunosuppressants taken were divided into acute myocardial infarction group(AMI,n=11),unstable angina pectoris group(USP,n=14)and stable angina pectoris group(SAP,n=7).The control group was composed of eight healthy volunteers(CON group).Theexpression of CD40L Was determined by flow cytometry(FCM).Serum sCD40L.ICAM-1 and VCAM-1 were determined by using ELISA.The serum hsCRP was assayed by using immunoturbidimetry.Data were analyzed with SPSS 11.0 software for windows.Results The expression percentage(%)of CD40L of the CD4+T cells,and the serum levels of sCD40L,hsCRP,ICAM-1 and VCAM-1were sifnificantly higher in patients of AMI group than those in patients of other groups(P＜0.05 or P＜0.01).Similarly,those biomarkers in patients of UAP group were usually higher than those in patients of CON or SAP groups(P＜0.05).There Was a positive correlation between the expression of CD40L and the serum level of VCAM-1 in paients of AMI group(P＜0.05),and likewise,a positive correlation also existed between the serum level of sCD40L and other factors,hsCRP,ICAM-1 as well as VCAM-1,in patients of AMI group(P＜0.05).Conclusions The enhanced expression of CD40L of the CD4+T cells and high serum level of sCD40L are present in patients with acute coronary syndrome.The hsCRP,ICAM-1 and VCAM-1 play roles in the pathogenesis of ACS,and they have correlation with enhanced expression of CD40L and high serum level of sCD40L.Therefore,CD40L and sCD40L may be used as indicators of risk in coronary heart disease.

Based on improving experimental operating skills of students and considering the features of microbiology experimental technology and methods,we developed a new examination ways of microbiology experiment — "multimedia papers of microbiology experiments" to use among 2005 and 2006 students of sophomore(entering campus in 2005 and 2006) of biotechnology and bio-science for microbiology experiment examination.Analysis of the results of experiment examination and theoretical examination for the 2005 and 2006 students showed that the disharmony and miscorrelation between experiment examination results and theoretical examination results were overcome,and students got more interested in experimental classes,while their experimental operation is more conscious and accurate.

The purpose of this study was to prepare tetramethylpyrazine hydrochloride transdermal gel and to study its permeation ability in vitro. The skin permeation ability was evaluated by Valian-Chien permeation cells with isolated rat skin. The concentration of tetramethylpyrazine in samples was determined by HPLC. The optimal formulation was composed with 5% azone, 5% peppermint oil, 8% sodium carboxymethylcellulose and 8% tetramethylpyrazine hydrochloride. The accumulative permeation amount of the gel was (6 731.87 +/- 102.31) microg x cm(-2) in 12 h,and the permeation rate was (535.02 +/- 33.89) microg x cm(-2) x h(-1). The release profile in vitro was in line with zero-order formulation. Tetramethylpyrazine hydrochloride gel prepared in the study would be developed as a novel transdermal preparation.

We examined the effects of conjugated linoleic acid (CLA) on growth, fatty acid composition and enzyme activity of fatty acid oxidation in the liver of large yellow croaker. We divided 1600 fish (average initial weight 150 g) into 4 groups and reared them in 8 cages. Four dietary treatments were formulated to contain 0%, 1%, 2% and 4% (w/w) CLA, respectively. The fish were fed for 10 weeks ad libitum twice daily. We found that the dietary CLA had no effect on growth, biometric parameters and whole body proximate (P>0.05), but showed some significant effects on the fatty acid composition in both muscle and the liver. The activities of lipogenic enzymes were slightly depressed in fish fed with increasing levels of CLA when compared with control (P>0.05). Dietary CLA supplementation had no effects on liver lipid content, but significantly increased the contents of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) (P<0.05) and decreased monounsaturated fatty acid (MUFA) content in both muscle and the liver. Dietary CLA inclusion resulted in significant increases of the biologically active cis-9, trans-11 and trans-10, cis-12 isomers in both tissues (P<0.05). The total accumulation of CLA was higher in the liver (3.83%, w/w) than in muscle (3.77%, w/w) when fed with 4% (w/w) CLA. This study demonstrates that large yellow croakers are capable of absorbing and depositing CLA and long-chain n-3 PUFA in the liver and muscle, showing that this species fed with CLA could be an important human food source for these healthful fatty acids.

We investigated the effects of fish protein hydrolysate (FPH) on growth performance and humoral immune response of the large yellow croaker (Pseudosciaena crocea R.). One thousand and two hundred large yellow croakers [initial average weight: (162.75+/-23.85) g] were divided into four groups and reared in floating sea cages (3 m x 3 m x 3 m). The animals were fed with 4 diets: basal diet only (control) or diets supplemented with 5%, 10% and 15% (w/w) FPH. The results show that dietary FPH levels significantly influenced the growth and immunity of the large yellow croaker. Compared with the control group, total weight gain (TWG) in all treatment groups, relative weight gain (RWG) and specific growth rate (SGR) in fish fed with diets supplemented with 10% and 15% FPH were significantly increased (P<0.05). Similar results were observed in immune parameters [lysozyme activity, serum complements, immunoglobulin M (IgM)]. Lysozyme activity, complement C4 and IgM were also significantly increased (P<0.05) in fish fed with diets supplemented with 10% and 15% FPH, while complement C3 level was significantly increased (P<0.05) in all treatment groups. In general, with the supplementation of FPH, particularly at dose of 10%, the growth performance and immunity of the large yellow croaker can be improved effectively.

OBJECTIVE: RNA interference technology (siRNA) was used to inhibit the expression of DJ-1 gene in lung squamous cell carcinoma SK-MES-1 cells, and the cell biological behaviors were investigated to explore the function of DJ-1 gene. METHODS: A targeted DJ-1 siRNA lentiviral vector with a green fluorescent protein (GFP) as a reporter was constructed. The constructed DJ-1 siRNA and control-siRNA vectors were infected into SK-MES-1 cells as experimental (DJ-1 siRNA) and control (Control siRNA) groups, respectively. The DJ-1 protein expression was determined by Western blot. The cell proliferation capability was measured with methyl thiazolyl tetrazolium (MTT). The cell cycle was analyzed by flow cytometry. The capability of cell migration was determined by Transwell method. RESULTS: Compared with control-siRNA and blank-control groups, the protein expression of DJ-1 gene was down-regulated, the capability of cell proliferation was obviously inhibited (P<0.01), the cell cycle was arrested with increased number of G1- and G2-phase cells and reduced number of S-phase cells, and the capability of cell migration was significantly decreased (P<0.01) in the DJ-1 siRNA-infected cells. CONCLUSION DJ-1 gene might play a role in promoting cell proliferation and cell migration capability in vitro in lung cancer SK-MES-1 cells.
