Objective:To determine drug dose and usage of timolol maleate eye drops in the treatment of superficial infantile hemangioma.Methods:A total of 250 superficial hemangioma infants were recruited and assigned into 5 groups (n=50 for each group):an external application group and 4 exterior coating groups (2,4,6,8 times per day).We evaluated the therapeutic effect of different methods for drug application (external application or exterior coating) and the frequency for drug administration on superficial infantile hemangioma.Results:The external application group (twice a day and 0.5 hour per time) showed better effect than that in the exterior coating group with twice a day (P＜0.001).The difference in therapeutic effect between the exterior coating group with 6 times a day and exterior coating group with twice a day or with 3 times a day was significant (P＜0.001).The differences in drug efficacy were not found among the exterior coating group with 6 times a day,the exterior coating group with 8 times a day,or the external application group with twice a day (All P＞0.05).Conclusion:Drug dose may affect the therapeutic effect oftimolol maleate eye drops in superficial hemangioma infants,and exterior coating with 6 times a day may achieve the best curative effect.

To explore the proportion for facial aesthetics that may be recognized by the potential group who will do plastic surgery in the future. 
 Methods: We measured the celebrity photos, who were born before 1980 recognizable by the people over 40 years old or by high school students. The proportions for facial aesthetics recognizable by these two generations were obtained and compared. 
 Results: Compared the new generation of male celebrities with the older generation of male celebrities, the difference was statistically significant by the independent samples t test (t=-2.502, P<0.05), while other ratios were not statistically significant (P>0.05). Compared the new generation of female celebrities with the older generation of female celebrities, the difference was statistically significant by the independent samples t test. The ratios between inter-canthic diameter and eyeslit breadth, mouth breadth and eyeslit breadth, stirnhohe and 1/3 of the physiognomic facial height, nasal height and 1/3 of the physiognomic facial height were significantly different (P<0.05), while other ratios were not significantly different (P>0.05).
 Conclusion: The young new generation loves more larger eyeslit breadth for men, while a larger eyeslit breadth, smaller bizygomatic breadth and sharper chin for women.

Objective: To study the effect of combining bcr-abl Aspo and c-myb Aspo on K562 cells. Methods: Cellswere exposed to oligomers. Cell inhibitory rate was determined by typan blue dye exclusion. CFU-K562 cells were culturedin 0.8% methyleellulose. P210 was measured by flow cytometry. Cellular bcr-abl mRNA was detected by RT-PCR semiquantitative analysis. Cell apoptosis was measured by flow cytometry and observed by electron microscope. Results: When the concentration of both bcr-abl Aspo and c-myb Aspo was 5 μmol/L, K562 cells were still growth in clone state. The growth inhibitory rate was 61.7% at 120 h. P210 was depressed at 24 h and went up to 25.7% at 120 h. The apoptosis rate was 22.5%. While K562 cells were dealt with 10 μmol/L bcr-abl Aspo and 10 μmol/L c-myb Aspo, the cells were growth in dispersal. The cell growth inhibitory rate reached to 92.2% and 64.3% of K562 cells were induced to apoptosisat 120 h. P210 was complelely depressed untill 120 h. The decrease of bcr-abl mRNA was from 69.2% to 85.3% after incubation 48 h with 5 μmol/L Aspo and 10 mol/L. Conclusion: It emerges coordination to combine bcr-abl Aspo and c-myb Aspo on K562 cells, and enhances the anti-leukemia effect.

Objective: To study the effect of combining bcr abl Aspo and c myb Aspo on K562 cells. Methods: Cells were exposed to oligomers. Cell inhibitory rate was determined by typan blue dye exclusion. CFU K562 cells were cultured in 0.8% methylcellulose. P210 was measured by flow cytometry. Cellular bcr abl mRNA was detected by RT PCR semiquantitative analysis. Cell apoptosis was measured by flow cytometry and observed by electron microscope. Results: When the concentration of both bcr abl Aspo and c myb Aspo was 5 ?mol/L, K562 cells were still growth in clone state. The growth inhibitory rate was 61 7% at 120 h. P210 was depressed at 24 h and went up to 25.7% at 120 h. The apoptosis rate was 22.5%.

AIM:To study the effect of bcr - abl gene antisense phosphorothioate oligonucleotides(Aspo) on K562 cell line and explore its significance in chronic myelogencous leukemia (CML) gene therapy. METHODS: Cells were exposed to oligomers, observed by inverted microscope. Cells inhibitory rate were determined by 0.4% trypan blue exclusion. CFU - K562 were cultured in 0.8% methylcellulose. P210 was measured by flow cytometry. RESULTS:K562 cells were treated with Aspo, they still grew in clone state and show antisense sequence specific and dose dependent. When the concentration of Aspo was more than 5?mol/L, the growth of cells was inhibited and P210 was down regulated or completely suppressed, and the greatest growth inhibition was at 120h. There was significant inhibition of cell proliferation in a rang of cells number from 1 ? 10-4/mL to 5 ? 10-4/mL after treatment with 10?mol/L Aspo. b2a2 Aspo was also effect on K562 cells which expressing b3a2 mRNA. CONCLUSION: bcr - abl Aspo has a specific growth inhibition effect on K562 cells, and worths further study in CML gene therapy.
