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.

Objective We observed the level of education of elderly patients with acute myocardial infarction (ami) influenced the level of awareness in the disease.Methods we used the questionnaire designed by ourselves to investigate the cognitive level of 80 cases with acute myocardial infarction.According to the education level of the patients,we divided them into different groups,including junior high group,secondary technical group,junior college group,and compared the different awareness levels of the three groups of patients with each other.Results The rate that the junior college group patients with AMI did not understand the risk factors were:diet70%,body weight 50%,smoking 70%,exercise40%,lipids 50%,blood pressure80%,blood sugar 50%,significantly lower than that of the secondary technical group of 38%,33%,47%,38%,42%,71%,42% and of the junior high school group,of 22%,18%,48%,16%,14%,45%,18% ( all P ＜ 0.05 ),The awareness of the disease in the junior college group of AMI was significantly higher than the secondary technical group and the junior high school group( all P ＜ 0.05 ).Conclusion The level of education and awareness of the disease in elderly patients with AMI was significantly related.

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.

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.

Objective To discuss the influence of blood exchange transfusions on hemato- microenvironment of neonates with hyperbilirubinemian.Methods Blood exchange transfusion was performed in 35 neonates.Mean transfusion volume was (136.9±27.4) ml/kg.The speed of blood exchange transfusion was 92 ml/(kg·h).Blood bilirubin,blood electrolyte,blood routine and blood sugar levels were measured before,during and after the transfusion.Results Serum total bilirubin (TB) decreased by 53.78% after blood exchange,but there was no change in Na~+,Cl~-,and blood sugar (P＞0.05),and K~+ was remarkably decreased from (4.45±2.40)mmol/L to (3.87±0.52)mmol/L (t=21.979,P＜0.05).TB,Hb,PLT,WBC,Ca~(2+) were decreased[TB from(511.52±80.21) μmol/L to (236.41±66.54) μmol/L;Hb from (145.20±11.70) g/L to (128.66±2.54) g/L;PLT from (207.84±70.67)×10~9/L to (134.86±48.61)×10~9/L;WBC from (16.90±10.56)×10~9/L to (8.94±7.44)×10~9/L,and Ca~(2+) from (1.26±0.32) mmol/L to (0.99±0.22) mmol/L,P＜0.05 or ＜0.01].Conclusions Blood exchange transfusion can not influence Na~+,Cl~-,and blood sugar,but has remarkable effect on total bilirubin,Ca~(2+),Hb,K~+,PLT,and WBC.
