Objective To investigate the quality of dissertations by analyzing the concealed evaluation results of postgraduate dissertations,and to provide a reference for improving the quality of dissertations.Methods A total of 366 postgraduate dissertations and 1 051 concealed evaluation comments were collected from a medical university,and according to the evaluation index system of postgraduate dissertations,a horizontal comparison was made based on the overall quality and discipline.Excel and SPSS 19.0 were used for statistical analysis.Results Eighty percent of the dissertations in unqualified category had poor topic selection,and the excellent and good rate was only 21％ in "Standardability".In discipline-based evaluations,the basic medicine group had a poor rate of 3.8％ in "Topic Selection" and 2.5％ in "Mastery of Basic Knowledge and Scientific Research Ability",while the military management group had a poor rate of 5.6％ in "Innovation and Value" and 1.9％ in "Standardability".Conclusion Topic selection is the key to the quality of dissertations,and the groups of basic medicine and military management should improve the scientificity of topic selection and the standardability of dissertations.

Objective To study the effects of combined plateau hypoxia and sodium cyanide on NOS activity and NO concentration.Methods Seventy-two male SD rats were randomly divided into two groups:plain(308 m) group(n=36) and plateau(4 000 m) group(n=36).After 3.6 mg/kg NaCN subcutaneous injection the activity of NOS and the concentration of NO of rat liver were determined at the time point of 0(contrd group),0.5,1,2,4 and 6 h.Results In both plain group and plateau group,NaCN administration produced the decrease of total NOS activity and the increase of iNOS activity of rats liver.The activity of iNOS in plain group increased more significantly than that in plateau group.NO concentration of plain group reached a peak value at 1 h.However,the NO concentration of plateau group increased at the time point of 30 min,and then decreased.Conclusion Plateau hypoxia combined NaCN intoxication may inhibit NO production of liver.
