简介：背景：研究表明GEF-H1能激活Rho蛋白，与肿瘤发生、发展、浸润、迁移等密切相关。目的：构建人pEGFP-GEF-H1载体并稳定转染结肠癌HCT116细胞后检测GEF-H1表达。方法：在线合成引物软件设计人GEF-H1基因引物，构建重组质粒pEGFP-GEF-H1，并转染结肠癌HCT116细胞，以转染空质粒和未转染的细胞分别作为空质粒组和空白对照组。荧光显微镜下观察绿色荧光蛋白表达，RT-PCR和蛋白质印迹法分别检测GEF-H1mRNA和蛋白表达水平。结果：成功构建了人pEGFP-GEF-H1载体，测序结果表明序列正确。转染重组质粒pEGFP-GEF-H1后，荧光显微镜下可见较强的绿色荧光，GEF-H1mRNA和蛋白表达水平均较空质粒组和空白对照组明显上调。结论：体外成功构建了人pEGFP-GEF-H1载体，且转染结肠癌HCT116细胞后高表达GEF-H1，为进一步探讨结肠癌与GEF-H1的关系提供了必要的实验材料。

简介：目的研究24h食管阻抗-pH监测中,熟练配合及护理对检查成功的重要性。方法通过对637例患者行24h食管阻抗-pH监测,对患者进行充分的术前准备、熟练的术中配合及术后护理。结果637例患者通过充分的术前准备、心理护理、熟练的术中配合及术后护理,均取得监测成功。结论充分的术前准备、心理护理、熟练的术中配合及术后护理,直接关系到监测的成功与诊断的准确性。
