Problems solved by technology

[0003] At present, Western medicine has many therapies and drugs for psoriasis vulgaris, but there are still many limitations in terms of safety, effectiveness, price, and service life.

For example, photochemotherapy (UVA, UVB) is the standard treatment for psoriatic skin diseases, but requires a corresponding treatment center, and has potential photosensitivity and carcinogenicity; topical treatment is usually suitable for skin lesions <5 % of patients with psoriasis, and for patients with moderate to severe psoriasis, topical therapy alone or in combination with phototherapy may not be sufficient; It should be treated systematically, but long-term application may cause adverse reactions such as liver and kidney damage

In recent years, there are a variety of high-efficiency biological agents available for the treatment of moderate and severe psoriasis, but long-term use of TNF-α inhibitors may increase the risk of tumors
