1.Discussions on the ownership and property right structure of public hospitals in China based on new institutionalism
Chinese Journal of Hospital Administration 2016;32(10):737-740
Based on the framework of new institutionalism,the paper defined the concept and history of public hospital′s attributes,dividing such hospitals into those built based on poverty alleviation and those on social identity priority.Considering the attributes of the public goods provided by public hospitals,the diversity of their investment,and attributes of their value production process,this paper probed into their property right arrangement.It is emphasized that such hospitals should enhance their key property right feature of public ownership,and on such basis their relationship with government and corporate governance establishment can be discussed.

Mangiferin, one of the active constituents of Rhizoma Belamcandae, in samples of Be-lamcanda chinensis (L.) DC. or its substitute was determined quantitatively by RP-HPLC. The 11 sam-ples collected from different localities for analysis were: 7 rhizomes of wildly grown or cultivated B. chi-nensis, 1 of its leaf and stem, and 3 substitutes (a wildly grown and another commercially available Iristectorum Maxim. and a I. dichotoma Pall. ). Results of the analysis showed that the contents of mangiferinin Rhizoma Belamcandae were significantly higher than that of its substitutes I. tectorum and I. di-chotoma. There were also certain significant differences between samples from different localities (P<0.05), but with no statistically significant difference between the rhizome or leaf and stem, neither be-tween cultivated and wildly grown samples, (P>0.05). The method was proved to be quick, simple andreproducible, and may provide a reliable basis for the quality control and evaluation of B. chinensis.

A new approach, combining microwave digestion and sensitive determination of selenium by a normal-phase high performance liquid chromatography after derivatization with 2,3-diamino-naphthalene was proposed to the measurements of trace selenium concentration in natural waters. Two digestions systems, I.e. HNO3 and H2SO4-H2O2, were evaluated and their working conditions were optimized. Under optimal conditions, this approach provides a detection limit of 7.2 pg (with HNO3) or 10.4 pg (with H2SO4-H2O2), a recovery of 99.1%~103.4%, as well as a linear range of 0~1.5 ng Se(Ⅳ). The approach was applied to determine Se concentration in 4 different types of environmental waters (sample volume: 2 mL) and the concentration levels of 0.20~0.90 μg/L were found, with recoveries of 99.1%~103.4% by standard addition.

Objective To observe the morphological damages of hyperbilirubinemia on rat central nervous system, and evaluate the therapeutic effects of different routes of basic fibroblast growth factor (bFGF) administration. Methods Totally 90 Wistar rats were inflicted to hyperbilirubinemia models and then divided randomly into 3 groups:untreated group (BG),treated-1 group (T_ 1 G), treated-2 group (T_ 2 G), and another 30 rats served as control group (CG). bFGF injection were given at 30 min, 1, 3, 5 and 7 d by abdominal cavity (T_ 1 G,) and cranial cavity (T_ 2 G). GAP-43 expression levels and the micro-morphological features were observed with immunohistochemical assay and transmission electron microscopy respectively at 2 nd, 8 st, 28 st and 60 st day. Results ①Hyperbilirubinemia rat model was verified by gross and microscopic observation, bilirubin concentrations in the plasma and brain.②Compared to CG, the expression level of GAP-43 was significantly up-regulated in BG, T_ 1 G and T_ 2 G, especially in the later 2 groups (P

Objective To prepare monoclonal antibody against Prostate Stem Cell Antigen(PSCA) and explore the inhibitory effects of Anti-PSCA mAb in treatments of human prostate cancer xenografts in mice. Methods Balb/c mice were immunized by PC-3 cell line. After fusing and screening, the anti-PSCA McAb’s characterizations were determined. Solid tumors in mice were produced by subcutaneous injection with PC-3 cells in the flanks of the mice.We picked out 10 mice bearing human prostate cancer xenografts.They were divided into a treatment group (n_1=5) and a control group (n_2=5).200 ?g Anti-PSCA mAb was injected into abdominal cavity of each mouse of the treatment group and PBS for them of the control group.Anti-PSCA mAb and PBS were administered once every three days for consecutive three times.The mice survival conditions of two groups were recorded during 5 weeks.The serum PSA, the tumor weights and dimensions of survived mice were measured.The tumor volume inhibition rate was calculated. T-test was performed to compare differences of PSA in serum,tumor weights and volumes between the treatment and control groups.Routine pathological slides of tumor tissue were observed under light microscope to evaluate the range of tumor tissues damaged by Anti-PSCA mAb. Ultrastructure was observed with transmission electron microscope. Results A marine McAb was produced, which raised against PSCA,belonged to IgG1 subclass. The average PSA serum level of the two groups were(3.28?0.55)ng/ml and(7.26?0.43)ng/ml.The weights of tumors of the two groups were(0.95?0.17)g and(3.08?0.18)g.The volumes of them were(164.59?14.08)mm3 and(548.49?19.79)mm3.There are remarkable differences between the treatment group and the control group(P
