Distribution characteristics of subtypes of HPV cervical infection / 国际检验医学杂志

ABSTRACT

Objective To investigate the female infection situation of human papilloma virus (HPV) and the distribution charac-teristics of HPV gene subtypes in the hospital ,so as to provide a theoretical basis for clinical prevention and treatment of HPV cer-vical infection and the study for developing the preventive HPV vaccine suitable for this hospital .Methods The PCR-reverse dot blot hybridization (PCR-RDB) was adopted to check the genotypes of HPV on the cervical samples in 625 gynecologic outpatients and inpatients .Results Among 625 cases ,210 cases were infected by HPV with the total HPV infection rate of 33 .6% .The single subtype infection was in 152 cases ,accounting for 72 .38% ,the mixed infection by more than or equal to 2 kinds of subtype was in 58 cases ,accounting for 27 .62% .The subtypes with the higher infection rate from high to low were HPV 58(7 .52% ) ,HPV16 (6 .72% ) ,HPV6(5 .76% ) ,HPV43(4 .80% ) ,HPV11(4 .64% ) ,HPV35(3 .36% ) ,HPV56(2 .56% ) ,HPV18(2 .40% ) ,HPV52 (2 .40% ) and HPV68(2 .40% ) .Conclusion The HPV infection rate in the gynecologic outpatients and inpatients in the hospital is high ,the subtype distribution is wider and is dominated by the high risk HPV infection .The most common subtype is HPV58 and multiple HPV infection rate is high .
