【摘要】 目的 探討MMP2、MMP9及MMP14在結直腸癌患者血清中的表達水平,并分析其與結直腸癌分化程度、Dukes分期及淋巴結轉移等病理參數的關系,以更好的指導臨床工作。方法 應用ELISA(酶聯免疫吸附實驗)分別檢測200例結直腸癌患者(觀察組)、60例健康成人(對照組)血清中MMP2、MMP9和MMP14的含量。結果 觀察組血清中MMP2、MMP9及MMP14表達量顯著高于對照組(P<0.01),觀察組中不同臨床特征患者血清MMP2、MMP9和MMP14的表達與腫瘤分化程度、Dukes分期以及淋巴結轉移有關(P<0.01),經相關性分析,MMP2和MMP9、MMP9和MMP14的表達呈正相關(P均<0.05)。結論 MMP2、MMP9和MMP14在結直腸癌患者血清中高表達,三者可能在結直腸癌發生發展中起重要作用;早期聯合檢測MMP2、MMP9和MMP14可能對判斷患者的預后及指導臨床治療有重要價值。

【Abstract】 Objective To observe the expressions of MMP2,MMP9 and MMP14 in patients with colorectal carcinoma,analyze their relationship with differentiation,Dukes stage and lymph node metastasis,investigate their clinical signifance.
Methods 200 patients withcolorectal carcinoma were collected as observation group.60 normal adults were collected as control group.The expressions of MMP2,MMP9 and MMP14 were detected by ELISA.Results The expressions of MMP2,MMP9 and MMP14 in the observation group were obviously higher than that of the control group(P<0.01). The expressions of MMP2,MMP9 and MMP14 were positively correlated with differentiation,Dukes stage and lymph metastasis in the observation group(P<0.01).Con
clusion The higher expressions of MMP2,MMP9 and MMP14 are found in colorectal carcinoma. The MMP2,MMP9 and MMP14 may predict the development to colorectal carcinoma.The combined examination of MMP2,MMP9 and MMP14 may be helpful to predict the prognosis in colorectal carcinoma.

結直腸癌是近年來較為常見的惡性腫瘤之一,其死亡患者均已發生了癌的轉移,因此,結直腸癌早期浸潤的判定已成為亟待解決的問題。血清中各種細胞因子對預后及治療的指導作用逐漸引起人們的關注[1]。基質金屬蛋白酶2(MMP2)、基質金屬蛋白酶9(MMP9)和基質金屬蛋白酶14(MMP14)是基質金屬蛋白酶家族(MMPs)的重要成員,在細胞外基質的降解和再塑中有重要作用。MMP2、MMP9均屬于鋅離子依賴性內太酶家族成員,具有降解IV型膠原、破壞基質膜、促進腫瘤細胞通過血管內皮進行侵襲轉移的作用。基質金屬蛋白酶14(MMP14)為膜型金屬蛋白酶。目前有關MMP2、MMP9和MMP14在結直腸癌中作用的報道較少。本研究采用ELISA(酶聯免疫吸附實驗)檢測結直腸癌患者血清中MMP2、MMP9和MMP14的表達情況,以探討MMP2、MMP9和MMP14表達水平與結直腸癌的發生發展及淋巴結轉移的關系、為判斷其預后提供理論依據。……
