组织芯片技术在乳腺癌相关指标检测中的应用

目的：探讨组织芯片免疫组化方法在乳腺癌相关指标检测中的应用。方法：采用组织芯片免疫组化和传统免疫组化的方法分别检测了183例和30例乳腺癌组织中MMP-2，MMP-9，MMP-13的表达水平。结果：组织芯片免疫组化染色与传统免疫组化染色不存在统计学差异（P〉0．05）。结论：高通量组织芯片免疫组化的方法在乳腺癌相关指标检测中可一次对多个样本进行多指标检测，大大节省了人力、物力和财力，值得进一步推广使用。     

Organ Specific Tumor Markers: What’s New?

Tumor markers are molecules produced in the body in response to cancer. An ideal tumor marker should have high sensitivity and specificity, should be cheap, and should be easily detected in body fluids. Identification of novel markers is important and it is expected that with the advent of newer technologies, more reliable markers will be discovered. This review discusses the currently available tumor markers for different malignancies.     

5-Fu对人胃癌细胞金属硫蛋白表达的影响

目的:探讨5-Fu对人胃癌细胞的杀伤作用及对金属硫蛋白(MT)表达的影响.方法:利用人胃癌BGC-823细胞株在培养过程中加入5-Fu继续培养5h或10h收获,然后用HE和免疫组化染色,光镜下进行观察.结果:实验组BGC-823细胞变形,MT表达强度和位置有明显变化.结论:5-Fu作用5h对胃癌细胞有杀伤作用,对癌细胞形态和MT的表达均有明显影响.
