Objective:To investigate the clinical efficacy of recombinant human interferon alpha -2b combined with Loop electro-sugical excision procedure( LEEP)in the treatment of cervical ectopic columnar epithelium with chronic cervicitis. Methods:The med-ical records of 68 cases of cervical ectopic columnar epithelium with chronic cervicitis in our hospital from April 2012 to April 2014 treated with LEEP were analyzed retrospectively. The control group(30 cases)was treated with LEEP combined with 5-day postopera-tive oral administration of antibiotics to prevent infection,and the treatment group(38 cases)was given recombinant human interferon alpha -2b through vagina additionally,every other day for 20 days every month after menstrua. After 6 courses of treatment,the clinical efficacy,vaginal bleeding time,vaginal discharge duration,wound healing time and HPV persistent infection were compared between the two groups. Results:The cure rate of the control group was 66. 67%,while that of the treatment group was 92. 11%,and the difference was significant(P<0. 05). Totally 19 cases in the control group were with wound healing(accounted for 63. 33%),while that in the treatment group was 32 cases(accounted for 84. 21%),the difference was significant(P<0. 05). And the vaginal bleeding time,vaginal discharge duration,and wound healing time of the treatment group were all significantly shorter than those of the control group(P<0. 05). After the treatment,the HPV persistent infection rate in the control group was 16. 67%,while that in the treatment group was 0%,and the difference was statistically significant(P<0. 05). The two groups during the treatment process had no obvious adverse reactions,indicating high drug safety. Conclusion:Recombinant human interferon alpha-2b combined with LEEP in the treat-ment of cervical ectopic columnar epithelium is safe and effective,which can effectively shorten the wound healing time,vaginal bleed-ing time and vaginal discharge duration,and is worthy of promotion in clinics.
