Abstract

The invention discloses microemulsion gel of an anti-human papillomavirus(HPV) plant extract and a preparation method and application of the microemulsion gel. The microemulsion gel comprises a plant extract and auxiliary materials, and the plant extract includes one or more of a rhizoma curcuma extract, a folium eucalypti extract, a radix sophorae flavescentis extract, a fructus cnidii extract, a radix stemonae extract and a cortex phellodendri extract. According to the invention, the natural plant extract not only can serve as a component of a carrier but also can serve as an active ingredient to enhance the medicine efficacy; by taking carbomer as a matrix, a local topical preparation with antibacterial, anti-inflammatory and antiviral functions is prepared; and the microemulsion gel used for HPV infection and prevention, bacterial and fungal vaginitis, cervical erosion, and daily care of women's private parts especially can reduce mRNA expression levels of key oncogenes E6 and E7 in Hela cells. The microemulsion gel prepared by the invention has high safety, high stability, convenience in administration and high patient compliance; and the processing technology is simple, cost is low and large-scale production is facilitated.

Description

technical field

[0001] The invention belongs to the technical field of medicine, and in particular relates to a microemulsion gel of anti-HPV plant extracts, a preparation method thereof and an anti-HPV application. Background technique

[0002] HPV, that is, human papillomavirus, has obvious characteristics of tropism for human skin and mucosal epithelial cells. The pathogenic mechanism of HPV is mainly related to immune escape: the virus integrates into granule molecules in epithelial cells, so that the virus cannot be detected by cells throughout its life cycle. The state of endolytic enzyme dissolution, thereby reducing the immune response of the body; after the HPV virus infects the body, it will also integrate its own genes into the host genes, further evading the monitoring of the immune system. HPV is divided into several subtypes, among which the mucotropic high-risk type is mainly HPV16 / 18, and the expression of related proteins is mainly regulated by E6 and E7 gen...
