AIM To study the anti-inflammatory effects and mechanisms of pristimerin. METHODS Several inflammatory models were established, such as ear edema induced by croton oil, hind paw swelling by carrageenan, elevation of capillary permeability by acetic acid in mice and a-cute peritonitis induced by carrageenan in rats. Protein content was measured by Coomassie brilliant blue method, nitric oxide (NO) content by Griess reaction assay, N-acetyl-?-D-glucosamini-dase (NAG) activity by colorimetry, superoxide dismutase (SOD) activity by hydroxylamine method, catalase (CAT) activity by ultraviolet spectro-photometry, and malondialdehyde (MDA) content by fluorescence method in peritoneal exudate in rats. RESULTS Pristimerin ip 0. 156 - 0. 625 mg ? kg-1 or im 1-4 mg - kg-1 inhibited ear edema, hind paw swelling, and elevation of capillary permeability in mice. In the rat peritonitis induced by carrageenan, pristimerin im 1 - 2 mg ?kg-1 reduced neutrophil counts, lessened protein and NO content, inhibited the production of MDA and decreased NAG activity, while augmented the SOD and CAT activity in exudate. CONCLUSION Pristimerin has a significant anti-inflammatory effect which may be related to the inhibition of NO production, scavenging oxygen free radicals, anti-lipoperoxidation and stabilizing lysosome membrane.

Objective To investigate in evaluation of various capacity requirement of probationer nurs-ing students by nurses in operation room in order to improve clinical teaching work. Methods A self-de-signed questionnaire was applied, 191 qualified teaching nurses from nine grade three A general hospitals in Beijing were invited to fdl the questionaires. The results underwent subsequent analysis. Results The teach-ers had high expectations for various capacity of the probationer nursing students. Conclusions Clinical teachers should establish feasible teaching scheme according to the existing teaching syllabus in order to in-crease teaching quality, make students gain new insights through reviewing old materials, so that they can mas-ter various technique in operation room in short time.

Objective To evaluate the role of several traditional laboratory examinations in identifying the cause of WBC count increase,which might be the adverse reaction of glucocorticoid or infection.Methods 74 patients treated in the hospital from Jan. 2011 to Dec.2012 were recruited in the study.Glucocorticoid without Infection(n =15 ),Infection without Glucocorticoid(n =29) and Infection with Glucocorticoid(n=30)Group were devided according to the type of disease and therapies.After being treated for 0,3,7 d,respectively venous blood samples of patients were collected to determine the concentration of CRP,WBC count,leukocyte classification and NAP score.CRP was used as the Judgment index for the degree of infection,the changes of other indexes were compared.Results Compared with the Infection without Glucocorticoid Group,the CRP concentration of the Infection with Glu-cocorcoid Group was becoming lower(P >0.05).The Non-infection with Glucocorticoid Group applied glucocorticoid for 3 days and 7 days respectively,the count of neutrophilic granulocyte and NAP score increased significantly compared with that before glucocor-ticoid application(P <0.01)while the count of lymphocyte reduced(P <0.05)and no significant change in the count of eosnophils (P >0.05).Conclusion The increase of WBC after glucocorticoid can not be identified whether it is the adverse reaction of glu-cocorticoid or aggravated infection by using classification of leukocyte,the increasing amount of WBC and NAP score.
