摘要: 目的:通过分析RIP140和LCOR在高级别鳞状上皮内病变(HSIL)细胞质和细胞核中的表达,寻找鉴别宫颈上皮内瘤变(CIN)Ⅱ级和Ⅲ级的生物标志物。方法:采用免疫组织化学法检测45例CIN Ⅱ级、32例CIN Ⅲ级及51例CIN Ⅱ级与CIN Ⅲ级复合形态的样本中RIP140和LCOR 在细胞质和细胞核中的表达情况。结果:细胞质和细胞核中RIP140在CIN Ⅲ级中的表达均高于CIN Ⅱ级,差异有统计学意义(P<0.05);细胞质中LCOR在CIN Ⅲ级和CIN Ⅱ级中的表达差异无统计学意义(P>0.05),细胞核中LCOR在CIN Ⅱ级中的表达高于CIN Ⅲ级,差异有统计学意义(P<0.05);细胞质中RIP140在复合形态样本中高表达较多,与CIN Ⅱ级比较差异有统计学意义(χ2 =4.868,P=0.027)。结论:RIP140在细胞核中的高表达对鉴别CIN Ⅱ级和CIN Ⅲ级具有辅助作用,其在细胞质中的高表达提示CIN Ⅱ级潜在合并更高级别鳞状上皮内瘤变。

Abstract: Objective: To analyze the expression levels of RIP140 and LCOR in cytoplasm and nucleus in high-grade squamous intraepithelial lesion(HSIL) in order to find new biomarkers for the identification of cervical intraepithelial neoplasia(CIN) Ⅱ and CIN Ⅲ. Methods: Immunohistochemistry was used to detect the expression of RIP140 and LCOR in cytoplasm and nucleus in 45 cases of CIN Ⅱ, 32 cases of CIN Ⅲ, 51 cases of CIN Ⅱ and CIN Ⅲ combined morphology. Results: The expressions of RIP140 in cytoplasm and nucleus of CIN Ⅲ were higher than those of CIN Ⅱ, with statistical significance(P<0.05). There was no statistically significant difference in the expression of LCOR in cytoplasm between CIN Ⅱ and CIN Ⅲ(P>0.05), but the expression of LCOR in nucleus of CIN Ⅱ was higher than that of CIN Ⅲ, with statistical significance(P<0.05). RIP140 was highly expressed in the cytoplasm of the complex morphologic samples, and the difference was statistically significant compared with CIN Ⅱ(χ2=4.868, P=0.027). Conclusion: The high expression of RIP140 in the nucleus has an auxiliary effect in distinguishing CIN Ⅱ from CIN Ⅲ, and its high expression in the cytoplasm suggests that CIN Ⅱ may have potential coexistence with high-grade squamous intraepithelial neoplasia.
