Warts is a common sexual contact spread disease, and the incidence is very high, usually due to unclean sex, so should pay attention to the traditional treatment is to use freezing, laser or microwave invasive treatment methods, but the recurrence rate is high, the pain is big, the treatment cycle is long. With the improvement of scientific level and medical progress, photodynamic treatment of warts has become the ideal choice for most patients, and its effect is obvious, no scars, short treatment cycle, less painful, recurrence rate is greatly reduced, and tighten the skin and other advantages more and more become its “core competitiveness”. Photodynamic is a non-invasive treatment of Hpv latent virus method, is currently the most advanced and the best method of international standards. That is, without damaging the surface of the skin, cytological removal of latent virus a way. First of all, use Ayla to compress on the suspicious area, Ayla is a photosensitive drug, retain the sealing package for three hours, three hours Ayla to recognize the latent Hpv virus, after three hours, the HPV latent virus becomes luminescent. Then, the wrap is removed and the package is illuminated with a large red light on all four sides, usually 635 nanometer red light, for twenty minutes on each side. The cervix uses a light column, and the urethra and anus use fiber optics. After the photo, the tissue cells undergo a subtle change known as apoptosis, which produces a single line of oxygen that kills the latent HPV virus cells. Generally, Ella Photodynamic is done once in 7 to 10 days, three times for a course of treatment. In one course of treatment, for low-risk latent Hpv clearance rate of 90% or more, high-risk latent Hpv clearance rate of 50% to 70% or more. Topical interferon and imiquimod and traditional Chinese medicine are used to consolidate and maintain the treatment, which usually lasts for three to six months. Three latent Hpv virus tests are conducted in the first, third and sixth month after the end of photodynamic therapy, and if both tests are negative within six months, the patient can be judged to be cured. The actual light power can be used to cure the warts.
