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。     

卡维地洛与络德治疗原发性高血压病的临床疗效分析

卡维地洛(carvedilol)是第3代非选择性β受体阻滞剂,它还具有钙拮抗剂作用,对氧自由基引起的心肌坏死、心律失常和细胞损伤等有保护作用.临床上用于治疗高血压病、冠心病和心律失常等.本研究采用随机、双盲,对照方法比较观察国产卡维地洛与络德(中外合资企业,成分为进口卡维地洛)治疗原发性高血压病的疗效及安全性.     

乙二胺四乙酸铁钠强化酱油可接受性的调查研究

为了解乙二胺四乙酸铁钠 (NaFeEDTA)强化酱油的接受程度 ,了解人们对铁营养知识和铁缺乏危害的认识情况 ,在贵州省对参加铁强化酱油干预试验的部分受试人群以家庭为单位进行问卷调查。共收回有效调查表 187份 ,基本上覆盖了试验点的各年龄组人群 ,具有较高的代表性。调查结果显示 :被调查者中 6 9 5 %认为铁强化酱油比未强化酱油有营养 ,2 8 9%认为铁强化酱油一般 ,只有 1 6 %中认为铁强化酱油差。 97 9%认为铁强化酱油可预防缺铁性贫血。 5 8 8%表示会选用铁强化酱油 ,另有 4 0 1%的人对是否选用拿不定主意。调查表明NaFeEDTA强化酱油有很高的可接受性 ,可接受度达 84 1% ,应用前景较好。     

乙二胺四乙酸铁钠强化酱油改善贫血效果观察

本研究比较了NaFeEDTA强化酱油、硫酸亚铁 (FeSO4)强化酱油对IDA改善效果。将 30 0名IDA学生分为对照组、NaFeEDTA强化酱油组Fe 5mg (人·日 )、FeSO4强化酱油组Fe5mg (人·日 ) ,比较新型铁强化剂 (NaFeEDTA)与传统铁剂 (FeSO4)对缺铁性贫血的改善作用。结果表明 ,对照组各项检验指标干预前后没有显著差异。其它各试验组呈现出较为一致的变化 ,表现为血红蛋白、血清铁、血清铁蛋白含量的显著性增加和原卟啉、总铁结合力、转铁蛋白的显著性下降。试验结果提示 ,乙二胺四乙酸铁钠与传统铁剂 (硫酸盐铁 )强化酱油均有改善学生贫血的作用 ,并且NaFeEDTA组的贫血改善率和Hb恢复水平优于FeSO4组。
