摘　　要：目的探讨Bex1和NF-kBp65在舌鳞状细胞癌组织中的表达及意义。方法免疫组化法检测60例舌鳞状细胞癌组织及相应癌旁正常组织中Bex1和NF-kBp65的表达情况,分析其与患者临床病理特征及预后的关系。结果舌鳞状细胞癌组织中Bex1阳性表达率为48.3%(29/60),低于癌旁正常组织的88.3%(53/60),差异有统计学意义(χ~2=22.18,P<0.01),其阳性表达率与TNM分期呈负相关(P <0.05);舌鳞状细胞癌组织中NF-kBp65阳性表达率63.3%(38/60),高于癌旁正常组织的20%(12/60),差异有统计学意义(χ~2=23.18,P<0.01),其阳性表达率与肿瘤TNM分期呈正相关(P <0.05)。Pearson相关性分析显示,Bex1和NF-kBp65的表达呈负相关(r=-0.302,P=0.019)。Kaplan-Meier生存曲线显示,Bex1阳性表达患者的生存率明显高于阴性表达患者。结论舌鳞状细胞癌组织中,Bex1阳性表达率低和NF-kBp65阳性表达率高可能对肿瘤的侵袭和转移起促进作用,且Bex1阴性表达可能与患者不良预后有关。Objective To investigate the expression of brain expressed X-linked gene 1(Bex1) and nuclear factorkBp65(NF-kBp65) in tongue squamous cell carcinoma, and its significance. Methods Immunohistochemistry was used to detect the expression of Bex1 and NF-kBp65 in 60 tongue squamous cell carcinoma(TSCC) tissues and adjacent normal tissues, and the relationships between Bex1,NF-kBp65 and the clinicopathological features and prognosis of patients were analyzed. Results The positive expression rate of Bex1 in TSCC was 48.3%(29/60), which was significantly lower than that in adjacent normal tissues 88.3%(53/60)(χ^(2)=22.18, P < 0.01). The positive rate of Bex1 was negatively correlated with TNM stage, and the difference was statistically significant(P < 0.05). The positive rate of 63.3%(38/60) in TSCC was significantly higher than 20%(12/60) in adjacent normal tissues(χ^(2)=23.18, P < 0.01), the positive rate of NF-kBp65 was positively correlated with TNM stage, and the difference was statistically significant(P <0.05). According to the Pearson correlation analysis results, the expression of Bex1 and NF-kBp65 in TSCC tissues was negatively correlated(r=-0.302, P=0.019). Kaplan-Meier survival curves showed that the survival rate of Bex1 positive patients was significantly higher than that of Bex1 negative patients. Conclusion In TSCC tissues, the low positive expression rate of Bex1 and the high positive expression rate of NF-kBp65 may promote tumor invasion and metastasis, and the negative expression of Bex1 may be related to the poor prognosis of patients.
