In present paper,we studied three kinds of method of assay for IL-1:thymocyte proliferation assay;L_(?) cell proliferation assay and pyrogen assay.Stimultaneously we used ~(125)I-UdR in stead of ~3H-TdR.The results show that all of three kinds of method of assay for IL-1 can measure IL-1 activity of supernatants from cultured rat alveolar M? stimulated by LPS in vitro.It suggests that ~(125)I-UdR can incorporate into DNA synthesis of cell and mouse fibroblast cell line L_(?) can response to IL-1 of supernatant from cultured rat alveolar M? stimulated by LPS.

· AlM:To compare the therapeutic effects of different surgical methods in treating pterygium patients and to observe tear film stability.
· METHODS: A total of 120 pterygium patients ( 120 eyes) were divided into three groups, each 40 cases (40 eyes).Data including SchirmerⅠtest (SⅠt), tear break-up time ( BUT) , corneal fluorescein staining ( CFS) were recorded preoperatively and postoperatively to evaluate the clinical efficacy of surgery and the effects of tear function changes.
·RESULTS:There were no significant differences in BUT in group A before the operation and one month after operation.Groups B and C showed significant difference before and after operation, but differences were not statistically significant ( all P<0.05 ); One month after operation, there was significant difference in CFS among group A, B and C (P<0.05), but the difference was not satistically significant between groups B and C; After 3mo, BUT in group A was not significant difference compared with the preoperative; but there was significant difference in groups B and C (P<0.05).When
compared it between groups B and C, there showed no significant difference; Group A showed no significant difference in SⅠt compared with preoperative, SⅠt of groups B and C were significant differences compared with preoperative (P<0.05), but no significant difference between the two groups;After 3mo, CFS of preoperative group A and group B and group C had no significant difference. After 10mo follow - up, there was axsignificant difference ( P<0.05 ) in recurrence rate in group A comparing with groups B and C, there were differences between groups B and C, but no statistically significant.Surgery is more likely to relapse in summer than in winter.
·CONCLUSlON: Pterygium excision combined with self-corneal limbal stem cell transplantation and Tenon capsule closed is an ideal surgical to reduce the recurrence and improve tear film function to some extent.

Objective To establish a multivariate reference range for ECG while considering the relation between multiple variables. Methods A total of 777 female undergraduates in a university were taken as the subjects and the P-wave amplitude was taken as an example to establish a multivariate reference range for P-wave amplitude by using Mahalanobis Depth Function. Results P-wave amplitude of the female undergraduates was established as follows, for a 95% CI of multivariate reference range,Depth≥0.035 521 6. Conclusion Multivariate reference range for ECG obtained in this study allows for a comprehensive utilization of the ECG data and can help the clinical diagnosis using ECG.

Objective To obtain the optimal solid dispersion prescription of the extract of Fructus Cnidii.Methods The release rate t63.2 was used as index and uniform design was used to investigate the effect of PEG,PVP,and Poloxamer on the release of the solid dispersion of the extract of Fructus Cnidii.Results PVP,PEG can delay the release of osthole from the solid dispersion,and tween-80 can promote its release.Conclusion The optimal solid dispersion prescription consists of tween-80(10.2 %),Poloxamer(79.8 %) and the extract(10 %).

Objective To study the effect of fund support on cited times of Chinese papers on AIDS by controlling the influence of confounding factors.Methods The effect of publication time of fund-supported papers and non fund-supported papers, h-index of authors, IF of journals on accumulated cited times of each academic paper was controlled by propensity score matching.The cited times of matched fund-supported papers and non fund-supported papers were compared by paired t test.Results The balance of confounding factors which were unbalanced before matching was achieved between fund-supported papers and non fund-supported papers after matching.No significant difference was found between fund-supported papers and non fund-supported papers after matching.Conclusion Fund support does not affect the cited times of Chinese papers on AIDS, which shows that fund support can not noticeably improve the academic level and impact of Chinese papers on AIDS.

Objective To develop the security scale of college students' sense to investigate college students' subjective feeling of security.According to the characteristics of the feeling tendentiousness to analysis the subject and object factors influencing the insecurity of college students.Methods The security scale of college students' sense compiled was administrated to 500 college student randomly stratified cluster sampling from four universities in Yantai,then description and analysis were analyzed by SPSS17.0,AHP and SAS9.1 to statistical.Results Through the scale of exploratory factor analysis,the Cronbach' s of the scale was 0.629.College students in four dimensions of security and total security were in above-average levels,college students' total scorc of security is significance of difference in grade,gender and whether come from the single parent(all P＜0.05) ;Self security was significance of difference in the grade and the gender(P＜0.01 and P＜0.05) ; and interpersonal security in gender and whether come from the single parent had significance difference(P＜0.05) ;Determine control and family security in these demographic variable aspects had no significant differences.Multivariate factors analysis results showed that the decision tree model was better than the logistic model (the misclassification rate of the model was lower than the decision tree model).The main factors affecting the university students' security were gender,grade,the average income and whether they,were the only children.The misclassification rate of the decision tree model was lower than the model of logistic.College students' sense of dimensions are significant with positive correlation,the dimension of the security level may affect other security of the situation.Conclusion The security scale of college students' sense has good reliability and validity and can be used in the study of college security.The factor analysis determines it can be used multiple factors analysis.The survey shows that the overall security of the crowd' s is over the average level.The gender,grade,annual per-capita income and whether the one-child are the potential factors that affect college students' insecurity.

Objective To explore the regularity and characteristics of violence-related injury. Method Data from the injury surveillance in the Emergency Medicine department of Nan-shan hospital was used in this study. Data of all injured patients, who admitied to the emergency department between 1 January 2004 to 31 November 2005, was analysed. Results During the study period, 25376 injured patients were collected and 12280 (48.4%) were violence-related injury patients. The male to female ratio was 2.4: 1. Most of patients were aged 15～44 years old, accouting for 79.9%. The majority of the violence-related patients were wonters, accounting for 59%, most injuries were open wounds and occurred in working places, injuries occurred most during 13 pm to 18 pm. Conclusions Analysis of data from the violence injury surveillance in emergency department can be an aid for the depiction of the overall severe injury profile in area and, in this way, it will be essential for the implementation of properly preventive and controlling measures, despite some limitation. It is urgent to explore and develop an violence injury surveillance system to cope China's milieu.
