Abstract

The invention discloses a composition for inhibiting HPV (human papillomavirus), a preparation and application thereof, the active ingredient in the composition is a cationic polymer, and the cationic polymer is a quaternized polysaccharide or/and a quaternized acrylamide copolymer. The composition can effectively inhibit HPV virus activity, can continuously act on a diseased region, almost has no stimulation and toxic and side effects on the diseased region, is high in activity utilization rate, obvious in treatment effect, not complex in preparation process and low in material cost, can be used in cooperation with other conventional treatment strategies, and has wide application prospects. The compound can be used for treating HPV infection and preventing cervical or other tissue lesions caused by HPV infection, and a new way is provided for clinically treating HPV infection and preventing HPV infection.

Description

technical field [0001] The present invention relates to the technical field of medicine, in particular to a composition, preparation and application for inhibiting HPV. Background technique [0002] Human papillomavirus (HPV) is a group of small non-enveloped DNA viruses belonging to the family Papillomaviridae, which can infect human skin and mucosal epithelial tissues, induce verrucous hyperplasia and even cause benign and malignant tumors. At present, more than 100 HPV virus subtypes have been isolated and identified. According to the different infection sites, HPV can be divided into two categories: dermatophilic group and mucosalophilic group. According to the difference of benign and malignant lesions induced by infection, the mucophagic group is divided into ①. High-risk HPV that induces malignant hyperplasia of epithelial tissue. High-risk HPV infection is closely related to the occurrence of cervical cancer and precancerous lesions; ②. Proliferative low-risk type, ...
