摘 要:目的 探讨Daxx与人乳头瘤病毒(HPV) 16 E6在宫颈病变中的表达情况及其意义.方法 对2010年9月至2013年11月就诊于中国医科大学附属盛京医院妇产科门诊活检或手术切除宫颈组织标本[其中宫颈癌63例,宫颈上皮不典型增生(CIN)Ⅲ44例,Ⅰ~Ⅱ45例,正常宫颈标本42例],采用免疫组化SABC法,检测Daxx及HPV16 F6的表达情况.结果 (1)在慢性宫颈炎、CINⅠ~Ⅱ、CINⅢ和宫颈癌中Daxx的阳性表达率分别为28.57%(12/42),40.00%(18/45),65.91%(29/44),66.67% (42/63),HPV16 E6为15.38%(6/39),36.17%(17/47),46.30%(25/54),100.00%(24/24);二者在宫颈高度病变组表达高于低级别组(P<0.05).(2) HPV16 F6高表达组的Daxx表达率高于HPV16 E6低表达组(P<0.05).(3) Daxx的表达与宫颈癌的病理分级、临床分期、淋巴结转移情况及患者年龄无关(P>0.05).(4) Daxx与HPV16 E6的阳性表达呈正相关(r=0.695,P<0.05).结论 Daxx和HPV16 E6随着宫颈病变级别的升高表达增加,两者可能存在某种协同作用,可能对宫颈病变发展起促进作用.Objective To investigate the expression of death domain associated protein (Daxx) and human papillomavirus 16 E6 protein (HPV16 E6) in cervical lesions and analyze their significance.Methods Immunohistochemical SABC method was used to detect the expression of Daxx and HPV16 E6 in 194 cases of cervical tissues with different lesions.Results (1) The positive expression rate of Daxx was 28.57% (12/42),40.00% (18/45),65.91% (29/44),66.67% (42/63),respectively,in chronic cervicitis,cervical intraepithelial neoplasia Ⅰ-Ⅱ (CIN Ⅰ-Ⅱ),CIN Ⅲ and cervical squamous cell carcinoma.The positive expression rate of HPV16 E6 was 15.38% (6/39),36.17% (17/47),46.30% (25/54),100.00% (24/24) in the above four groups.The positive rates in cervical cancer group and high grade CIN group were significantly higher than these in low level of CIN group and chronic cervicitis group (P 〈0.05).(2) The expression of Daxx was stronger in HPV16 E6 high positive group than that in HPV16 E6 low positive group (P 〈 0.05).(3) There was no significant relationship between the expression of Daxx and pathological classification,clinical stage,situation of lymph node metastasis or patients' age in cervical squamous cell carcinoma (P 〉 0.05).(4) There was significant positive relationship between Daxx and HPV16 E6 expression (r =0.695,P 〈 0.05).Conclusions The expression of Daxx and HPV16 E6 gradually increases with cervical lesion degree aggravating.Here might be synergy between them,and both could promote the development of cervical lesions.
