[摘要] 目的 探讨MCM2、Rb蛋白在鼻咽癌中的表达以及临床意义。 方法 通过使用免疫组织性化学检测方法,对2010~2015年期间在我院进行诊疗的60例鼻咽癌患者作为研究对象。分析患者的鼻咽正常黏膜组织标本中的MCM2、Rb的表达水平情况如何。 结果 有远处转移组的MCM2的表达水平不同于无远处转移组。患者中的人鼻咽癌组织中的MCM2的阳性率为84.00%,相較于正常鼻咽黏膜组织,明显优于正常的鼻咽黏膜组织(69.45%),两者之间差异具有统计学意义(P<0.05)。Rb蛋白在患者的鼻咽黏膜组织中的阳性表达率为71.90%,相较于正常鼻咽黏膜组织明显优于正常情况,差异有统计学意义。 结论 MCM2、Rb蛋白能够很好的对人体中的鼻咽黏膜中癌细胞的增长状态进行反应,从而使得患者的病情能够很快的得以确认,对患者病情诊断以及后期预后诊疗存在显著的临床意义。

[Abstract] Objective To investigate the expression of MCM2 and Rb protein in nasopharyngeal carcinoma and its clinical significance. Methods 60 cases of nasopharyngeal carcinoma were detected by immunohistochemical method in our hospital from 2010 to 2015. The patients MCM2, Rb expression level of nasopharyngeal normal mucosal tissue samples were analyzed. Results The expression level of MCM2 in distant metastasis group was different from that in no distant metastasis group. The positive rate of MCM2 in nasopharyngeal carcinoma tissues was 84.00%, which was significantly higher than that in normal nasopharyngeal mucosa (69.45%). And there was significant difference between the two groups (P<0.05). The positive expression rate of Rb protein in nasopharyngeal mucosa was 71.90%, which was significantly different from that of normal nasopharyngeal mucosa. Conclusion MCM2 and Rb proteins can react well to the growth status of cancer cells in the nasopharyngeal mucosa of the human body, so that the patients condition can be confirmed quickly. There is a significant clinical diagnosis of the patients condition and late diagnosis significance.

鼻咽癌病症的病情初期阶段较为隐匿,不够典型,并且较易产生淋巴结转移,因此通过对鼻咽癌患者的早期病情进行诊断[1],从而推进患者的后期病情确诊及预后情况是其诊治的关键性因素,并且其存在的发生转移机制在当前针对该种病情的研究中仍然并不明确[2]。在该种病情的产生过程中,MCM2以及Rb蛋白在患者体内进行复制的过程以及患者的鼻咽细胞周期中起着较为明显的表达作用,因此当前有较多数的研究是针对微染色体维持蛋白,在患者的体内表达阳性的情况就是该种细胞具有明显的传递复制能力标志[3],细胞的退出增值周期则表达较不明显,由此展现细胞的组织分化感染

已经进入了GO期阶段,由此对于鼻咽癌病情的早期诊断以及病情的后期诊疗[4],提供了相对较为固定的标记性。基于此通过采用免疫组织化学对60例鼻咽癌患者,不同组织性病变标本中的MCM2、RbD蛋白的表达情况,从而探讨其在鼻咽癌早期诊断中的临床价值所在[5-6]。……
