11006 EMEA首次采用快速建议程序

欧洲药品管理局（EMEA）完成了“科学建议和资料援助新框架”，新框架将显著改变EMEA对新药研究开发提供科学建议的方式。框架主要内容有： 从申报前期到科学建议被最终采纳，内部和外部专家可更早、更系统地介入；     

当爱恨情仇遇到百年老酒《老龙口》三部曲--酒的礼赞

康熙年间，山西太谷县酿酒作坊主孟子敬因山西连年大早，无粮酿酒，便前来大清发祥地——盛京重操旧业，开起了义龙泉酒作坊。从此也开始了344年的“关东第一窖”老龙口酒文化。而与此一起开始的还有与老龙口息息相关的人们的爱恨情仇。当爱恨情仇遇到了百年的老酒，醇厚吞绵就这样开始了……

现代医学200词——138．黏附分子

所谓黏附分子是指存在于细胞表面，参与细胞间或细胞与细胞外基质的粘附的分子群的总称。广义来说，纤维连结蛋白、层粘连蛋白、透明质酸等细胞外基质的构成成分也是由细胞分泌并存在于细胞表面，也可归入黏附分子的范畴。但狭义所指的黏附分子是指贯通细胞膜的糖蛋白或构成细胞膜的糖脂质。膜贯通型糖蛋白黏附分子按其构造特征可分为若干家族。在免疫系统中的黏附分子主要分为整合素家族、免疫球蛋白超家族、选择素家族、钙粘素家族、连接蛋白家族以及唾液粘蛋白家族等。     

FasL基因表达对缺氧状态下直肠癌细胞增殖凋亡的影响

Objective To elucidate the effect of FasL gene expression on the proliferation and apoptosis of hypoxic rectal carcinoma cells. Methods The normoxic expression level of FasL in HR-8348 subtype cells (HR-8348B, HR-8348L, HR-8348F and HR-8348As) with different invasive power were verified by Western blot. Hypoxia models for HR-8348B, HR-8348L, HR-8348F and HR-8348As were constructed with chemical modeling, then the FasL levels in all groups at 12 h after hypoxia were quantitated by Western blot. Distribution of different cell life cycles was determined with flow cytometry. Cell reproductive activities were detected with MTT method, and cell apoptesis was assessed with TUNEL. Results FasL protein was pigmentized at the position of 40 000 by Western blot, and the expression level of FasL was significantly higher in HR-8348F cells than those in HR-8348B, HR-8348L and HR-8348As cells(F=361.149, P<0.01) in normoxia. At 12 h after hypoxia, the FasL level was also significantly higher in HR-8348F cells than those in other groups (F=278.766, P<0.01), but was not markedly different as compared to themselves in normoxia (t=1.762, P>0.05). The proliferation index was significantly higher in HR-8348F (60.43±3.72) than those in HR-8348B (40.01±3.30), HR-8348L (41.30±4.06) and HR-8348As cells (35.87±4.39), respectively (F=39.477, P<0.01). However, both inhibition rate of proliferation and apoptotic index were remarkably lower in HR-8348F (17.30±1.98 and 13.10±1.04) than those in HR-834B (33.70±4.33 and 21.60±1.31), HR-8348L (34.20±3.92 and 20.10±1.15), and HR-8348As (38.00±4.55 and 23.90±1.23), respectively (F=28.811 and 76.462, respectively, P<0.01). Conclusion The expression enhancement of intracellular FasL in rectal carcinoma in hypoxia can lead to accelerated proliferation and reduced apeptosis of cells, which will promote tumor cells to adapt microenvironmental hypoxia.

季节指数法在传染病预测中的应用

传染病发生的时间分布具有短期波动、季节性升高、长期变异和一定的周期性。传染病报告制度的建立提供了疫情时间序列的原始数据,为数学模型的建立、疫情的预测奠定了基础。本文试用季节指数法对传染病的未来发展提供变动趋势、变动方向、变动程度等方面的定性和定量化的估测,为传染病的管理决策提供依据。
