摘要: 目的:通过分析RIP140LCOR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45CIN Ⅱ级、32CIN Ⅲ级及51CIN Ⅱ级与CIN Ⅲ级复合形态的样本中RIP140LCOR 在细胞质和细胞核中的表达情况。结果:细胞质和细胞核中RIP140CIN 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LCORCIN 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LCORCIN 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 =4.868P=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 lesionHSIL in order to find new biomarkers for the identification of cervical intraepithelial neoplasiaCIN and CIN . 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 and CIN combined morphology. Results The expressions of RIP140 in cytoplasm and nucleus of CIN were higher than those of CIN Ⅱ, with statistical significanceP<0.05. There was no statistically significant difference in the expression of LCOR in cytoplasm between CIN and CIN Ⅲ(P>0.05), but the expression of LCOR in nucleus of CIN was higher than that of CIN Ⅲ, with statistical significanceP<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 from CIN Ⅲ, and its high expression in the cytoplasm suggests that CIN may have potential coexistence with high-grade squamous intraepithelial neoplasia.
