At present, the assessment of the same hospital at the same time by different means may lead to different assessment results, viz. there may be a variety (inconsistency) of assessment results. This can be chiefly attributed to the variety of assessment systems, with different assessment indexes and assessment methods, and to the variety of people making the assessments and assessing environments. Integrated measures can be taken in order to render assessment results more accurate: ① refusing to have blind faith in any particular method; ② seeing clearly assessment goals and features; ③ properly selecting index systems for the assessment; ④ correctly fixing the weights for indexes; ⑤ appropriately selecting assessment methods; ⑥ making combined use of various methods; ⑦ pooling the results from different assessment methods.

Objective To investigate the possible mechanism of recombinant human erythropoietin (rhEPO) neuroprotection by studying the effect of rhEPO on expressions of matrix metalloproteinase-9 (MMP-9) and BCL-2 following focal cerebral ischemia-reperfusion in rats. Methods A rat middle cerebral artery occlusion/reperfusion (MCAO/R) model was induced by the intraluminal filament method, and intraperitoneal injection of rhEPO was used for intervention. Histopathological changes were observed by HE staining, and the expressions of MMP-9 and BCL-2 in the cerebral cortex of ischemic side were detected with immunohisto-chemistry. Results HE staining: At all time points, the numbers of surviving nerve cells were significantly higher in the rhEPO group, and their injury degree was significantly lower. MMP-9 immunohistochemistry staining: The positive cells were observed occasionally in the normal control group and the sham-operation group; the MMP-9 positive cells at the ischemic side of brain tissue in a normal saline control group began to appear at 6 hours after reperfusion, it reached the peak at 24 hours and began to decrease at 72 hours; the change trend of MMP-9 positive cells in the rhEPO group was similar to that in the normal saline control group, but it was significantly lower than that in the normal saline control group at the same time points (t were 12. 023 6, 12. 635 0, 12. 779 6, respectively, all P <0. 01). BCL-2 immunohistochemistry staining: No positive cells were found in the normal control group and sham-operation group. The numbers of BCL-2 positive cells reached the peak at the ischemic side of brain tissue in the normal saline control group at 6 hours after reperfusion, it reached the peak at 24 hours and further decreased at 72 hours; the change trend of BCL-2 positive cells in the rhEPO group was similar to that in the normal saline control group, but it was significantly higher than that in the normal saline control group at the same time points (t were 5. 763 1,8. 110 1, and 5. 798 7, respectively, all P <0. 01). Conclusions rhEPO may inhibit cortical neuronal apop-tosis at the ischemic side by inhibiting MMP-9 expression and up-regulating BCL-2 expression so as to play a neuroprotective effect.

Objective:To develop a scale used to measure smoking-related attitudes in Chinese secondary school students. Methods:Based on literatures published in China and abroad and suggestions by relevant specialists and teachers, we developed a self-administered scale with 16-item used to measure smoking-related attitudes in Chinese secondary school students. Factor analysis was used to assess the construct validity of the scale. The differences of the scores between trying smokers and non-smoker, and males and females were tested for assessing the discriminant validity of the scale. Cronbach's alpha for the total scale and the sub-scales was calculated for evaluating the internal consistency, and the split-half reliability test analysis was also conducted. Moreover, 112 subjects were re-investigated after two weeks of the first survey, and the difference and correlation of scores between the two surveys were tested for assessing the stability of the scale. Results: Factor analysis identified two potential components that could explain 46.2% of the total variance, and the first factor including 9 items was defined as "The opinions to tobacco and smoking-related behaviors", and the second one including 7 items was defined as "The opinions to measures for preventing and controlling smoking". The mean score of the scale in non-smokers was significantly higher than that of the trying smokers, while the mean score in females was significantly higher than that in males. The Cronbach'? coefficient was 0.87 for Factor One, 0.75 for Factor Two, and 0.86 for the general scale, and the coefficient of the split-half reliability was 0.71 for Factor One, 0.59 for Factor Two, and 0.72 for the general scale. By analyzing the data of 112 students who participated in both surveys, we obtained test-retest reliability of factorⅠas 0.72, of factor Ⅱ as 0.44 and of all items as 0.67, and all the correlation coefficients were statistically significant. There were no differences for the scores of the scale between the two surveys. Conclusion: The results indicated that the smoking-related attitude scale had reasonable validity and reliability,It could provide valuable reference for future similar surveys in China.
