长安福特:切莫因小失大

凭借新福克斯,福特在中国打了一个漂亮的翻身仗,继续发力中国。相比通用和大众,福特已经慢了半拍,好在我们还是看到了福特的觉醒,懂得迎合中国消费者的口味,翼虎的国产让福特终于赶上了SUV大热的末班车。但是最近长安福特的一些做法,让人不得不替他忧心,消费者     

5-氨基乙酰丙酸光动力疗法对人卵巢癌细胞的杀伤作用

目的 探讨5-氨基乙酰丙酸(5-aminolevulinic acid,5-ALA)介导的光动力疗法(photodynamic therapy,PDT)对体外培养的人卵巢癌3AO细胞的杀伤效应.方法 显微镜观察细胞形态;MTT法检测5-ALA介导的PDT(5-ALA-PDT)对3AO细胞增殖的抑制作用;PI染色及Annexin V-PI双染结合流式细胞术分析5-ALA-PDT对3AO细胞的细胞周期及死亡方式的影响.结果 5-ALA-PDT后3AO细胞出现典型的凋亡形态学改变;细胞抑制率随着5-ALA浓度及激光能量密度的升高而升高(P<0.01),当光敏剂浓度达到一定水平时,抑制率不再相应升高,该作用存在浓度饱和现象;流式细胞术显示PDT后细胞发生了G0/G1期生长停顿(P<0.05),有明显的晚期凋亡和继发性坏死(P<0.01).结论 5-ALA对卵巢癌3AO细胞有杀伤作用;凋亡是5-ALA-PDT杀伤卵巢癌细胞的一种机制.     

热休克蛋白70反义寡核苷酸联合化疗药物抑制肝癌细胞HepG2增殖的实验研究

目的研究热休克蛋白70反义寡核苷酸(HSP70ASODN)联合化疗药物对肝癌细胞的增殖抑制作用。方法采用MTT法比较转染组和未转染组联合化疗药物在肝癌细胞增殖方面的差异。结果检测HepG2细胞株对化疗药物5-氟尿嘧啶(5-Fu)的敏感性,24、48、72、96h未转染组与转染组的细胞生长抑制率分别为:0.323±0.043、0.468±0.015,0.394±0.045、0.663±0.026,0.526±0.021、0.793±0.041,0.616±0.016、0.899±0.044(P均<0.05)。检测HepG2细胞株对化疗药物ADM的敏感性,24、48、72、96h未转染组与转染组的细胞生长抑制率分别为:0.157±0.021、0.421±0.037,0.394±0.045、0.574±0.037,0.293±0.036、0.637±0.019,0.302±0.023、0.658±0.038(P均<0.05)。结论 HSP70ASODN能增强化疗药物对HepG2的增殖抑制作用;HSP70ASODN联合多药化疗优于联合单药化疗。     

Preliminary study on Salvia miltiorrhiza bung endophytic fungus

Objective To select the strains which can produce tanshinone ⅡA like its host plant Salvia miltiorrhiza bung. Methods A total of 50 strains of endophytic fungi were isolated from healthy, living and symptomless tissues of Salvia miltiorrhiza bung, among which 29 strains were obtained from the root, 14 from the stem, 3 from the leaf, 3 from the flower and 1 from the seed. Their antimicrobial activities against nine different bacteria, including both Gram-negative and Gram-positive bacteria, were measured by Oxford plate agar diffusion bioassay. Results Our data showed that all but four strains had significant antibacterial activities on at least one indicator bacterium to some extent, and five strains (DR1, DR4, DR16, DR18 and DF2) manifested quite prominent antibacterial activities against certain pathogenic bacteria. In some degree, it might indicate that this endophytic fungus isolated from the tissues of Salvia miltiorrhiza bung has a potential value as a natural antibacterial medicine as well. Thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC) were carried out to test selected strains, both inside and outside of the cell to see if any strain can produce tanshinone ⅡA. The result showed that extracts from three strains, labeled as DR12 (outside cell), DR21 (inside cell) and DF3 (inside cell), had a component with the same Rf value in TLC assay as that of authentic tanshinone ⅡA. The extract from DR12 (outside cell) and DR21 (inside cell) had a peak at retention time identical to that of authentic tanshinone ⅡA in HPLC. Conclusion The fungi appear to produce the bioactive compound tanshinone ⅡA, and they could be used to produce tanshinone ⅡA by fermentation. It provides a new way to synthesize this natural medicine.
