目的 　研究乙酰肝素酶（HPA1）在結(jié)直腸癌中的表達(dá)，探討其與腫瘤生長(zhǎng)和預(yù)后的關(guān)系。
方法 　采用RT-PCR和免疫組織化學(xué)技術(shù)，從mRNA和蛋白水平對(duì)HPA1在結(jié)直腸癌及其周圍組織中的表達(dá)進(jìn)行定性和定位研究，初步分析其與結(jié)直腸癌臨床病理特征和臨床預(yù)后的關(guān)系。
結(jié)果 　HPA1 mRNA在結(jié)直腸癌組織中的表達(dá)明顯高于周圍正常組織，HPA1 mRNA在正常腸道組織中的表達(dá)與是否患結(jié)直腸腺瘤呈正相關(guān)（r=0.352，P=0.024）； 免疫組化結(jié)果發(fā)現(xiàn)，HPA1蛋白主要表達(dá)在結(jié)直腸癌組織、腫瘤邊緣的浸潤(rùn)組織和血管內(nèi)皮細(xì)胞； HPA1陰性患者的2年無(wú)病生存率（88.9%）高于HPA1陽(yáng)性患者（50.0%），但差異無(wú)統(tǒng)計(jì)學(xué)意義（P=0.078）。
結(jié)論 　HPA1在結(jié)直腸癌組織中呈高表達(dá)，與腫瘤的發(fā)生和預(yù)后有一定的關(guān)系。
