a efficacy and safety study of composite gel containing black raspberry extract in removing hpv from patients with cervical intraepithelial neoplasia(cin) after cervical conization

Conditions: Cervical Intraepithelial Neoplasia; HPV

Summary: to evaluate the efficacy and safety of composite gel containing black raspberry extract in removing hpv from patients with cervical intraepithelial neoplasia(cin) after cervical conization

a large number of basic research and animal experiments have confirmed that black raspberry and its active ingredients are used for chemo-prevention of tumors. in recent years, it has been reported that black raspberry extract can effectively inhibit the proliferation of human oral cancer cells and colorectal cancer cells and promote its apoptosis. at the same time, studies have found that chemically modified lactoglobulin exhibits highly potent antiviral activity against human papillomavirus (hpv) infection, including hpv6, hpv16 and hpv18, and can be used as an effective and safe antiviral drug for treatment and prevent hpv infection. this study attempts to apply black raspberry and lactoglobulin to remove hpv virus and prevent cervical cancer, in order to make breakthroughs in the prevention and control of cervical cancer.
