OBJECTIVE:To prepare silybin liposomes(SLBL)coated by N-trimethyl chitosan(TMC)(TMC60-SLBL),and to optimize the formula. METHODS:The effects of 3 kinds of preparation methods on encapsulation efficiency of SLBL were com-pared,including film dispersion method,multiple emulsion method and reverse evaporation method. The formula of TMC60-SLBL was optimized by orthogonal test using encapsulation efficiency as index with the concentration of phospholipid,ratio of phospholip-id to cholesterol,ratio of silybin to lipids,hydration temperature as factors. The stability of TMC60-SLBL by optimal formula at 4 and 25℃within 30 d,the particle size and Zeta potential of TMC60-SLBL and SLBL were all compared. RESULTS:The encapsu-lation efficiency of TMC60-SLBL prepared by the film dispersion method was the highest,without statistical significance in encap-sulation efficiency before and after cutting (P>0.05). The optimal formula was with the concentration of phospholipid 6 mg/ml;the ratio of phospholipid to cholesterol 40∶1;the ratio of silybin to lipids 1∶30;the temperature of hydration medium 45 ℃;the encapsulation efficiency were(82.08±2.6)%,RSD=3.17%(n=3). The preparation was stable at 4℃;the mean diameter of SL-BL and TMC60-SLBL were(131.9±1.9)nm and(161.2±2.0)nm,and Zeta potential respectively were(-23.18±1.14)mV and (36.73 ± 2.84) mV. CONCLUSIONS:TMC60-SLBL is prepared successfully,and its formula is simple and practicable with high encapsulation efficiency.

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.

Objective To investigate the features of immune response of human immunodeficiency virus type-1 (HIV-1) antigen specific T lymphocytes in HIV-1 monoinfected or HIV 1/hepatitis C virus (HCV) coinfected individuals.Methods Twenty-six HIV-1 monoinfected and 23 HIV-1/HCV coinfected individuals were enrolled.Immunomagnetic microbeads were used to isolate T lymphocyte subpopulation CD4+ T cells and CD8+ T cells from human peripheral blood mononuclear cells (PBMC).Frequencies of interferon-γ (IFN-γ) secreting cells of CD4+,CD8+ T lymphocytes and PBMC stimulated by a peptide pool containing 12 overlapping peptides in HIV-1 P24 from 49 patients were assessed by enzyme-linked immunospot (ELISPOT) assay.HIV-1 RNA levels of these patients were also detected by real-time fluorescence quantitative polymerase chain reaction.The data were compared by one-way ANOVA and Mann-Whitney U test,and Spearman test was used for correlation analysis.Results Frequencies of HIV-1 antigen specific CD4+ T lymphocytes [median =25 spot-forming cells (SFC)/106 cells] were significantly lower than those of CD8+T lymphocytes (median=38SFC/106 cells,F=4.592,P=0.037) and PBMC (median=53 SFC/106 cells,F=5.436,P=0.025) in HIV-1 monoinfected group.Frequencies of HIV-1 antigen specific CD4+ T lymphocytes (median=5 SFC/106 cells,Z=-2.432,P=0.015),CD8+T lymphocytes (median=5 SFC/106 cells,Z=-1.996,P=0.046) and PBMC (median=10 SFC/106 cells,Z=-2.306,P=0.021) in HIV-1/HCV coinfected group were significantly lower than those in HIV-1 monoinfected group.Conclusions In HIV-1 infection,antigen specific immune response of CD4+ T cells can be activated,but weaker than that of CD8+ T cells.Co-infection with HCV might down-regulate the responses of HIV-1 antigen specific T lymphocytes in HIV-1 infected individuals.
