目的

研究梗阻小肠组织中水通道蛋白3(AQP3)的表达并分析其意义。

方法

对25例正常小肠、25例充血水肿小肠组织和坏死小肠组织行病理切片和苏木精-伊红染色、AQP3免疫组织化学染色,观察结构变化及AQP3表达情况。

结果

正常小肠AQP3呈强阳性表达,随着小肠梗阻病程的进展,小肠充血水肿,纤维组织增生及血管扩张,AQP3的表达随之降低,差异有统计学意义(P<0.001)。进展至坏死阶段,小肠组织结构的破坏,AQP3呈零表达,AQP3表达降低的小肠梗阻患者炎性反应更严重(P<0.05)。

结论

自正常小肠至坏死小肠,AQP3的表达呈阶梯式下降,提示AQP3可能是预示梗阻小肠坏死的可靠标志物。

Objective

To study the expression of aquaporin 3 (AQP3) in obstructive small intestinal tissues and analyze its significance in clinical practice.

Methods

Pathological sections, hematoxylin eosin staining (HE), and AQP3 immunohistochemical staining were performed in 25 normal small intestine, 25 hyperemic edema and 25 necrotic small intestine, to observe the structural changes and AQP3 expression status.

Results

The expression of AQP3 was strongly positive in normal small intestine. With the progression of small intestinal obstruction, intestinal congestion and edema, fibrous tissue hyperplasia, and vascular dilatation occurred. In parallel, the expression of AQP3 was significantly decreased in hyperemic edema small intestine compared to normal small intestine (P<0.001). AQP3 showed no expression in necrotic small intestine due to the destruction of small intestine, when progressing to the necrotic stage. The small intestinal obstruction patients with decreased AQP3 expression tended to have higher systemic inflammation than those with high AQP3 expression (P<0.05).

Conclusion

As the degree of necrosis worsens, the expression of AQP3 decreases in a gradient manner, suggesting that AQP3 may be a reliable marker for predicting necrosis of the obstructed small intestine.
