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.     

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。

光学干涉断层成像在冠心病介入诊断与治疗中的应用

光学干涉断层成像（OCT）成像特点与血管内超声（IVUS）相似，但是具有更高的分辨率和对比度，其分辨率可达10μm。有报道显示，血管内OCT可以得到高质量的图像，能够清楚地显示血管的解剖结构。体外试验显示通过OCT检查判断斑块特点，与组织学检查结果高度一致。猪冠状动脉血管成形术后行OCT检查可以发现微小的夹层。人体试验中显示OCT能够显示不同种类斑块的不同影像特征。本研究的目的为评价OCT在冠状动脉介入诊断与治疗中的可行性与有效性。     

顺铂分次给药在肺癌化疗中的临床观察

顺铂(DDP)是肺癌化疗中最常用的抗肿瘤药物之一,它引起的胃肠道反应、肾功能损害及骨髓抑制常使化疗难以顺利完成,顺铂的疗效和不良反应与其剂量呈正相关,但在相同剂量下其不良反应是否与用药方法有关尚无明确依据,我科从2002年1月～2004年7月将62例接受大剂量顺铂联合化疗的肺癌患者随机分为两组,在总剂量相同情况下比较顺铂一日用药与三日用药两种方法的疗效和不良反应。现报道如下:1临床资料1.1观察对象:62例均经病理或细胞学确诊为肺癌。KPS评分>70分,患者随机分为A、B两组。其中A组30例,男18例,女12例,中位年龄55.2岁,鳞癌12例,腺…
