A randomized controlled study was conducted to determine the effects of vaginal estrogen and human interferon alpha 2b vaginal effervescent capsules on vaginal microecology in perimenopausal and postmenopausal women. To determine whether there is a synergistic effect between the two in the treatment of HPV infection in perimenopausal and postmenopausal women. To observe the effects of two drugs alone and combined on the vaginal immune environment of patients.

After pre-enrollment screening, patients who met the inclusion criteria signed informed consent and were divided into interferon group, promestriene group and interferon + promestriene combination group according to the randomized controlled number table.

① Interferon group: human interferon alpha 2b vaginal effervescent capsules were given vaginal medication, one capsule a day for 10 days, for a course of treatment, a total of 3 courses of treatment. ② Promestriene group: Promestriene cream vaginal medication, once a day, 0.1g each time, 10 days, for a course of treatment, a total of 3 courses of treatment. ③Interferon + promestriene combination group: interferon 1 grain + promestriene cream 0.1g, vaginal medication, once a day, continuous use for 10 days, for a course of treatment, continuous use of 3 courses of treatment. Vaginal secretions were collected before treatment and one week after treatment to detect vaginal microecology. Flow cytometry was used to detect the proportion of immune cells in vaginal secretion. ELISA was used to detect immune-related cytokines (IFN-γ, TNF-α, IL-2, IL-4, IL-6, IL-10) in vaginal secretions.

HPV was reviewed at 1 month and 1 year after drug cessation.

Inclusion Criteria:

• The age of 45-65 years (inclusive);

  • HPV test indicates positive cervical and vaginal high-risk HPV;

    • Cervical HSIL was excluded according to the 2015 US Transitional Clinical Guidelines for Cervical Cancer Screening.

      • Patients with high-grade cervical intraepithelial lesions, who have undergone cervical conotomy or have undergone total or subtotal hysterectomy in the past, and HPV tests indicate high-risk cervical and vaginal HPV infection;

        • If the combination of clear vaginal inflammation, symptomatic treatment is needed, then the group test;

          • If the patients were complicated with abnormal uterine bleeding or postmenstrual bleeding, the reproductive system tumor should be excluded and cured, and then the patients were re-enrolled.
