摘　　要：目的:探讨基质金属蛋白酶(MMP)-2、MMP-7、MMP-9和基质金属蛋白酶诱导因子(EMMPRIN)在结、直肠癌中的表达以及在结、直肠癌发展过程中的作用。方法:采用免疫组织化学法检测100例结、直肠癌组织中MMP-2、MMP-7、MMP-9和EMMPRIN的表达。结果:MMP-2、MMP-7、MMP-9和EMMPRIN在结、直肠癌组织中的表达在结、直肠癌的浸润深度、Dukes分期和有无淋巴结转移间差异均有统计学意义(P<0.01);EMMPRIN分别与MMP-2、MMP-7、MMP-9蛋白在结、直肠癌组织中的表达呈正相关关系(P<0.01)。结论:MMP-2、MMP-7、MMP-9和EMMPRIN在结、直肠癌的演进过程中可能具有一定的协同作用。Objective： To investigate the expressions of matrix metalloproteinases-2,7 and 9（ MMP-2,MMP-7 and MMP-9） and extracellular matrix metalloproteinase inducer（ EMMPRIN） and their roles in the development process of colorectal carcinoma.Methods： The protein expressions of MMP-2,MMP-7,MMP-9 and EMMPRIN in 100 colorectal carcinoma tissue samples were detected by immunohistochemical method. Results： The differences of the expressions rates of MMP-2,MMP-7,MMP-9 and EMMPRIN in colorectal carcinoma tissue samples with different invasion depth,Dukes stage and lymph node metastasis were statistically significant（ P〈0. 05）. The expressions between EMMPRIN and MMP-2,MMP-7 and MMP-9 in colorectal carcinoma tissue were significant positive correlation,respectively（ P〈0. 01）. Conclusions： The expressions of MMP-2,MMP-7,MMP-9 and EMMPRIN have synergetic effects in the development of colorectal carcinoma.
