MTT colorimetry was used to examine the effect of PGL3-DF3-DTA on the growth of human breast cancer cells.

构建重组表达载体PGL3-DF3-DTA，并用其转染DF3阳性和阴性的乳腺癌细胞MCF-7和MDA-MB-231。

Resistance ratio of common Gram-negative bacilli to CAZ is high and tend to increase further.

结论常见革兰阴性杆菌对CAZ的耐药率有逐渐上升的趋势，要严格限制该药的不合理应用。

RESULTS:（1）Three KDR-siRNA expression vectors were digested by Nde Ⅰ and Sma Ⅰ and produced two fragments of 713 bp, 5 480 bp and 2 403 bp, 3 790 bp, respectively, which were congruous with expectation.

KDR-小干扰RNA对A549细胞中KDRmRNA水平的影响：与阳性对照组、阴性对照组、空白对照组和正常对照组的A549细胞相比，KDR-siRNA1，2，3表达载体转染后的A549细胞KDR基因表达水平均明显受到抑制，抑制率分别为64%、81%和72%，其中以KDR-siRNA2抑制作用最为明显。

The most common bacteria isolated from the conjunctiva are small numbers of coagulase-negative staphylococcus and diphtheroids.

从结膜最常分离的细菌包括少量的凝固酶阴性葡萄球菌和类白喉菌属。

CEA, CA242 and CA19-9 were examined conjunctively, which positive findings were 85. 0% and its sensitivity、specificity、 positive predictive value and negative predictive value were 85.0%、 80.0%、 89.5% and 72.2%respectively.

CEA，CA242和CA19-9组合检测，阳性率可达85.0%，其诊断的灵敏度、特异度、阳性预测值、阴性预测值分别为85.0%、80.0%、89.5%、72.2%。

Two different murine models (IFN γ or IL 4 gene knockout C57BL/6 mice,15 mice each strain) were contagiously infected with P.carinii by cohousing with P.carinii positive mice for 3,5,7 weeks as well as 15 gene un knockout C57BL/6 mice for infection control group.

分别用IFN γ或IL 4基因敲除的C5 7BL 6小鼠(各 15只作为动物模型)与未经基因敲除的C5 7BL 6小鼠(15只作感染对照组)，以密切接触的方式，使小鼠自然感染卡氏肺孢子虫；同时设非感染组 15只小鼠作阴性对照。
