摘要: 目的:观察基质金属蛋白酶-9(MMP-9)及其mRNA在胃癌中的表达特点,探讨其与Ⅳ型胶原的破坏程度之间的关系。 方法:74例胃癌标本,经免疫组织化学染色、原位杂交及形态定量分析方法,对同一肿瘤组织进行MMP-9、MMP-9mRNA、Ⅳ型胶原的检测,并结合临床病理参数进行综合分析。 结果:MMP-9及其mRNA的表达均与癌组织的浸润深度、分化程度、淋巴结转移有关;随着Ⅳ型胶原连续性的降低,MMP-9阳性病例数不断增高,但各组间差异尚无统计学意义。 结论:胃癌细胞自身具有产生与分泌MMP-9的能力,其对肿瘤的浸润、转移具有促进作用;MMP-9的产生、分泌及发挥降解功效是在机体内环境的严格监视控制之下进行的。

Abstract: Objective To investigate the expressions of MMP-9 and MMP-9 mRNA in gastric carcinoma and their correlations with the degradation of type Ⅳ collagen. Methods The expressions of MMP-9,MMP-9 mRNA and type Ⅳ were observed by immunohistochemistry,in situ hybridization and morphometric analysis in 74 cases of gastric carcinoma.The relationships between the expressions and the clinical parameters were analysed. Results The expressions of MMP-9 and its mRNA were closely related to the invasion, differentiation and lymph nodes status of the gastric carcinoma.With the degradation of type Ⅳ collagen,the MMP-9 positive cases were increased.However,the difference among the groups had no statistical significance. Conclusion Gastric carcinoma cells have the ability to produce and secret MMP-9 which can promote the invasion and metastasis of the neoplasm. The production,secretion and function of MMP-9 were extremely controlled by the regulation of internal environment.

Key words: gelatinase B, type Ⅳ collagen
