摘要:

目的:研究舌鳞状细胞癌(TSCC)组织中Livin和细胞色素C(Cyt-C)的表达,
观察其表达水平与TSCC临床病理特征的关系,并探讨TSCC组织中Livin和Cyt-C蛋白表达的相
关性。方法:采用免疫组织化学SP法检测48例TSCC和10例正常舌黏膜组织中Livin和Cyt-C蛋
白的表达,并分析其与患者的性别、年龄、组织学类型和淋巴结转移等临床病理特征的相关性。结果:Livin主要表达在细胞浆中,TSCC和正常舌黏膜组织中Livin蛋白阳性表达率分别为66.67%和0%,二者比较差异有统计学意义(P<0.01);Livin的高表达与TSCC组织
学分化程度有关联(P<0.05),并与颈淋巴结转移有关联(P<0.05)。Cyt-C主要表达在细胞
浆中,TSCC和正常舌黏膜中Cyt-C蛋白阳性表达率分别为70.83%和10.00%,二者比较差异有统计学意
义(P<0.01);Cyt-C蛋白阳性表达率与组织学分化程度有关联(P<0.05)。Spearman等级相关分
析,TSCC组织中Livin和Cyt-C蛋白表达呈正相关关系(r=0.553,P<0.001)。结论:TSCC组织中L
ivin和Cyt-C蛋白表达呈正相关关系,二者的联合检测有助于临床判断TSCC恶性程度和评估
预后。

Abstract:

Objective To investigate the expressions of Livin and cytochrome C( Cyt-C) in tongue squamous cell carcinoma (TSCC) tissue and to
 explore the correlation between their expression levels and  the   clinicaopathological characteristics of TSCC and the correlation between expressions of Livin an
d Cyt-C protein in TSCC tissue. Methods The expressions of Livin and Cyt-C protein were examined by immunohistochemistry SP method in 48 cases of TSCC and 10 casesof normal tongue tissue,and  the relationship between the expressions of Livin,Cyt-C protein and the   clinicopathological characteristics,such as gender,age,histological type and lymph node metastasis were analyzed. Results Livin mainly expressed   in the cytoplasm. The pos
itive expression rates of  Livin protein in TSCC and normal tongue tissue were 66.67% and 0%,respectively,and there was significant difference  (P<0.01).The  high
 
expression of Livin was correlated to the histological differentiation degree of TSCC (P<0.05),and also closely correlated to the cervical lymph node metastasis (P<0.05). Cyt-C  mainly expressed   in the cytoplasm. The positive expression rates of Cyt-C protein in TSCC and normal tongue tissue were 70.83% and 10.00%,respectively,and there was  significant difference (P<0.01).The  expression of Cyt-C was correlated to the histological differentiation of TSCC (P<0.05).The Spearman analysis results showed that  there was a positive correlation between the expressions of Livin and Cyt-C protein  in TSCC tissue(r=0.553,P<0.001). Conclusion There is a positive correlation between the expressions of Livin and Cyt-C protein in TSCC tissue. Combined detection of livin and Cyt-C will help to judge the  malignant degre
e of TSCC and evaluate the  prognosis.
