The publication and citation of academic papers are important indexes to evaluate science research level of colleges and institutes and also important index to evaluate researchers. In this paper we calculated and analyzed the number of publications, cited number, and cited frequency of SCI papers in three military medical universities and one military medical research institution from 1997 to 2006, and put forward some opinions and suggestions.

Objective To study the clinical methods and effects of root cause analysis on the application of the Swiss cheese model in the psychiatric nursing adverse events. Methods Safety management groups were established to train nurses, use Swiss cheese model to analysis the root cause,formulate the corrective measures. The annual rates of incidence and reporting rate of adverse events were compared. Results One year after the root cause analysis on the application of the Swiss cheese model,the annual number of patients increased from 3 420 to 3 730,the cases of nursing adverse events reduced from 141 to 120,and the rate of nursing adverse events dropped from 4.12 percents to 3.21 percents (X2=4.16,P<0.05). The reporting cases of nursing adverse events increased from 65 to 102,and the reporting rate of nursing adverse events enhanced from 46.10 percents to 85.00 percents ( X2=42.57,P<0.01). Conclusions The use of root cause analysis on the application of the Swiss cheese model is the effective management model to analyze the nursing adverse events and to improve the nursing safety.

Objective To investigate the molecular mechanism of CCl_(4) inducing fibrosis in hepatic stellate cells.Methods The expression of Transforming growth factor-?1(TGF-?1) at mRNA and protein level were detected by RT-PCR method and Western blot analysis.The proliferation and cell cycle distribution were detected with MTT method and flow cytometry.Results After treatment by(10 mmol/L) CCL_(4) for 24 hours,the mRNA and protein expression of TGF-?1 in CCl_(4) group sharply increased.In the meantime,the proliferation of CCl_(4) group cells was markedly increased.There were less G_(0)/G_(1) phase_() cells and more G_(2)/M phase cells in CCl_(4) group than those in control group.Conclusion Suitable CCl_(4) may increase the expression of TGF-?1 and the proliferation of hepatic stellate cells,which is one of mechanisms leading to hepatic fibrosis.

[Objective]To measure the contents of rhychophyline in uncaria,and its regularity of variety with decoction time.[Methods]RP-HPLC method was used.The chromatographic conditions were listed below:Hypersil-BDS C18 column(150mm?4.6mm.5?m),amobine phase composed of metranol-water(70∶30),a flow rate of 1ml /min and wave lengths was 254nm,column temperature was 25 ℃.[Results]In the range of 0.19?g ~0.95?g,the linear was very well between the content of rhychophyline and peak area.[Conclusion]The contents of rhychophyline in decoction reached the peak at 11.4min after uncaria was added in boiling water.

Objective To determinate the weights coefficient of the comprehensive evaluation indexes in medical waste management objectively and scientifically.Methods The analytic hierarchy process was used to define the weight coefficients in 9 synthetic evaluation indexes.Results The biggest weight coefficient(0.311 7)was handling medical waste standardly,the consistent ratio(CR)being 0.005 5

Objective To investigate the prevalence and the associated risk factors of fatty liver disease in railway employees.Methods 3 520 railway employees aged 21～60 were observed,1 299 cases of fatty liver who were diagnosed by uhrasonography and 2 221 normal controls.Plasma triglycerides(TG),total cholesterol(TC)and fasting blood glucose(FBG) were determined.Results The prevalence rate of fatty liver was 36.9%(1 299/3 520).It increased with age.The prevalence rate of fatty liver in the groups with different age was significantly different(x~2=14.82,P
