摘要:

目的:探讨MMP-9和TIMP-1 mRNA在食管鳞状细胞癌和对应癌旁组织中的表达差异
及其相关性。方法:选取新鲜手术切除的食管癌标本98例,每例分别取癌组织和对应的癌旁组
织各1份,采用RT-PCR法检测MMP-9和TIMP-1 mRNA在食管鳞状细胞癌组织和对应癌旁组织中的表达,分析食管癌组织中M
MP-9和TIMP-1 mRNA表达与临床病理特征的关系;采用Pearson相关分析法分析
MMP-9与TIMP-1 mRNA在食管鳞状细胞癌组织中表达率的相关性。结果:食管癌
组织中MMP-9 mRNA阳性表达率高于癌旁组织,阳性表达率比较差异有统计学意义(χ2=22.873,P=0.000);食管癌组织中TIMP-1 mRNA阳性表达
率高于癌旁组织,阳性表达率比较差异有统计学意义(χ2=7.864,P=0.005)。
MMP-9 mRNA表达率与食管鳞状细胞癌浸润深度有关联(χ2=5.022,P=0.025),与食管
鳞状细胞癌淋巴结转移无关联(χ2=0.617,P=0.432)。TIMP-1 mRNA的表达与食管鳞状细胞
癌浸润深度有关联(χ2=4.982,P=0.026),与食管鳞状细胞癌淋巴结转移无关联(χ2=0.527,P=0.468)。MMP-9 mRNA与TIMP-1 mRNA在食管鳞状细胞癌组织中
的表达率呈正相关关系(r=2.237,P=0.028)。结论:MMP-9和TIMP-1 mRNA表达可能参与
了食管鳞状细胞癌的发生发展,但在食管鳞状细胞癌淋巴结转移方面可能不发挥关键作用。

Abstract:

Objective To explore  the differences of the  expressions of MMP-9 and
 TIMP-1 mRNA in  esophageal squamous cell carcinoma tissue and the matched adjacent normal tissue
 and their relationships. Methods 98 spicemens of surgical removed esophageal carcinoma tissue were chosen for detection,the carcinoma tis
sue and the  adjacent normal tissue  were cut and stored simultaneously from every spicemen,respectively.RT-PCR method was used to detect the expressions of MMP
-9 and TIMP-1 mRNA in  esophageal squamous cell carcinoma tissue and the  adjacent normal tissue;the relationships between the expressions of MMP-9 and
TIMP-1 mRNA in esophageal squamous cell carcinoma tissue and clinicopathological characteristics were analyzed.The relationship between the expressions of MMP
-9 and TIMP-1 mRNA in carcinoma tissue was analyzed by Pearson related analysis method.Results
The positive expression rate of MMP-9 mRNA in carcinoma tissue was higher than that  in    adjacent normal tissue
(χ2=22.873,P=0.000), and the positive expression rate of TIMP-1 mRNA in carcinoma tissue was higher than that
 in   adjacent normal tissue (χ2=7.864,P=0.005).There was  correlation  between the positive expr
ession of MMP-9 mRNA and the depth of tumor infiltration(χ2=5.022,P=0.025), but there was no correlation  between the positive expression of MMP-9 mR
NA and lymph node metastasis(χ2=0.617,P=0.432).There was  correlation  between the positiv
e expression of TIMP-1 mRNA and the depth of tumor infiltration(χ2=4.982,P=0.026), but there was  no correlation  between the positive expression o
f TIMP-1 mRNA and lymph node metastasis(χ2=0.527,P=0.468). The  positive expression of MMP-9 mRNA  in
esophageal  carcinoma tissue had positive correlation with the expression of TIMP-1 mRNA(r=2.237,P=0.028).
Conclusion The expressions of MMP-9 and TIMP-1 mRNA may play a very important role in  the development of esophageal squamous cell carcinoma,however both of them have no affection on lymph node metastasis of esophageal squamous cell carcinoma.

Key words: esophageal squamous cell carcinoma, matrix metalloproteinase-9, tissue inhibitor of metalloproteinase-1
