Abstract:

Abstract:Objective To investigate the expression and significance of aquaporin-3(AQP-3) in oral squamous cell carcinoma(OSCC). Methods A immunohistochemistry method,Envosion,was employed to test the manifesting levels of AQP-3 in pathological slices of 60 OSCC cases and 10 normal cases,and the results were treated with comparison and statistical analysis. Results In 60 OSCC cases,AQP-3 mainly manifested in membrane,and a little in cytoplasm. The positive manifesting rate of AQP-3 in the samples was 81.7%,which was significantly higher than the manifesting rate of 20.0% in normal oral mucous membrane(P < 0.05). In OSCC tissues,the manifestation of AQP-3 was not correlated with the age(χ2 = 0.032,P > 0.05),gender(χ2 = 0.045,P > 0.05),or location(χ2 = 1.313,P > 0.05). However, the manifestation of AQP-3 was correlated with the different pathological grades(χ2 = 8.626,P < 0.05),clinical phases(χ2 = 21.59,P < 0.05) and lymph node metastasis(χ2 = 3.90,P < 0.05). Conclusion The abnormal manifestation of AQP-3 is closely related with the occurrence and development of OSCC. Therefore,it can be used assubsidiary index for OSCC treatment and prognosis.

摘要:

目的 探讨水通道蛋白-3(AQP-3)在口腔鳞状细胞癌(OSCC)组织中的表达及其意义。方法 应用免疫组化Envosion法,检测山西省人民医院病理科2009年9月至2013年7月存档的60例OSCC病理组织石蜡标本和10例正常口腔黏膜上皮组织中AQP-3蛋白的表达水平并进行比较分析。结果 在60例OSCC的病理标本中AQP-3主要表达在细胞的胞膜上,也有少量表达在胞浆中。AQP-3在OSCC标本中的阳性表达率(81.7%)明显高于在正常口腔黏膜组织中的阳性表达率(20.0%),差异有统计学意义(P < 0.05)。OSCC组织中AQP-3的表达在不同年龄(χ2 = 0.032)、性别(χ2 = 0.045)、病变部位(χ2 = 1.313)方面的差异均无统计学意义(均P > 0.05),在不同组织分化程度(χ2 = 8.626 )、临床分期(χ2 = 21.59 )以及是否有颈淋巴结转移(χ2 = 3.90)方面的差异有统计学意义(均P < 0.05)。结论 AQP-3的异常表达与OSCC的发生、发展有密切关系,可作为OSCC治疗和预后的辅助性指标。
