Abstract:
Objective To observe the expression and relevance of human papillomavirus L1 (HPVL1)capsid protein and tumor suppressor gene p16~4A in cervical lesions.Methods The expression of HPVL1 capsid protein and p16INK4A in liquid-based cytology specimens and organization from 210 cases infected with HPV virus were detected by Max-vision immunohistochemistry method.Results In different grade of liquidbased cytology specimens,the positive rates of HPVL1 capsid protein had statistic difference (x 2 =70.50,P ＜ 0.005).The rate in LSIL couples was 68 ％ (34/50),which was the highest in all couples.The positive rates of tumor suppressor gene p16INK4A were increased gradually.In SCC couples,the positive rates was 100 ％(30/30),which was the hishest.In LISL couples,the rate of HPVL1+ p16INK4A-was 32 ％ (16/50),which was the hishest.In SCC couples,the rate of HPVL1-p16INK4A+ was 100 ％ (30/30),which was the highest.In orgnizational specimens,the positive rates of HPVL1 capsid protein in cervical intraepithelial neoplasia had statistic difference (x2 =54.37,P ＜ 0.005).The rate in CIN Ⅰ group was 60.4 ％ (32/53),which was the highest.The positive rates of tumor suppressor gene p16 were increased gradually.In cervical cancer group,the positive rate was 100 ％ (28/28),which was the highest.In CIN Ⅰ group,the rate of HPVL1+ p16INK4A-was 45.3 ％ (24/53),which was the highest.In cervical cancer couples,the rate of HPVL1 (-) p16INK4A(+) was 100 ％ (28/28),which was the highest.Conclusion Detection on the expression of HPVL1 capsid protein and tumor suppressor gene p16INK4A can diverse different levels of cervical lesions and separate cases from aggravated or self-healing,to avoid over-treatment or misdiagnose.
