【摘要】：目的檢測細胞外基質金屬蛋白酶誘導因子(EMMPRIN)在大鼠腎間質纖維化模型中的表達變化。方法 64只Sprague-Dawley大鼠隨機分為假手術組(Sham組)和模型組(UUO組),每組16只。假手術組,僅游離輸尿管不結扎,模型組,行單側輸尿管結扎術,分別于術后3、7、14 d處死大鼠并留取腎臟組織。腎臟標本行HE、Masson染色方法檢測間質纖維化損傷的程度。應用免疫組織化學方法檢測腎組織中EMMPRIN,α-SMA,E-cadherin的表達。結果 HE染色顯示:UUO術后腎間質腎小管萎縮、擴張,胞外基質沉積,炎細胞浸潤增加。Masson染色顯示:UUO術后大鼠腎組織膠原纖維組織增生,出現(xiàn)明顯的間質纖維化改變。免疫組織化學結果顯示:與假手術組相比,UUO模型3 d組的EMMPRIN表達顯著增高,同時有α-SMA表達升高和E-cadherin表達顯著下降(P0.05);隨著梗阻時間的延長,模型7 d組EMMPRIN的表達逐漸減弱(P0.05)。結論EMMPRIN可能參與了UUO大鼠腎間質纖維化的早期上皮間質轉分化過程,而隨著纖維化程度加重,后期表達逐漸減少。
[Abstract]:Objective to investigate the expression of extracellular matrix metalloproteinase-inducible factor (EMMPRIN) in rat renal interstitial fibrosis model. Methods Sixty-four Sprague-Dawley rats were randomly divided into sham-operated group (Sham group) and model group (UUO group, 16 rats in each group). The model group was treated with unilateral ureteral ligation. The rats were killed on the 14th day after operation, and the renal tissue was taken. The degree of interstitial fibrosis was detected by HEMA Masson staining. The expression of EMMPRIN, 偽 -SMA-E-cadherin in renal tissue was detected by immunohistochemical method. The results showed that the expression of EMMPRIN, 偽 -SMA-E-cadherin in renal tissue was detected by HE staining. It shows that the renal tubules atrophy in the renal interstitium after the operation of the UUO, Dilatation, deposition of extracellular matrix, increased infiltration of inflammatory cells. Masson staining showed the proliferation of collagen fibers in renal tissue of rats after WUO. The results of immunohistochemistry showed that the expression of EMMPRIN was significantly increased, and the expression of 偽 -SMA and E-cadherin decreased significantly in the 3-day group compared with the sham-operated group, and the expression of E-cadherin decreased significantly with the prolongation of the time of obstruction, and the expression of 偽 -SMA and E-cadherin decreased significantly with the prolongation of the time of obstruction. Conclusion EMMPRIN may be involved in the process of early epithelial stromal transdifferentiation of renal interstitial fibrosis in UUO rats, but the expression decreases gradually with the severity of fibrosis.
