Brief Summary

Psoriasis is a common chronic, inflammatory disease characterized by skin changes and joint involvement. About 50% of patients with psoriasis have damage to the nail, especially in pustular psoriasis in the continuous acromegaly dermatitis. Common damage includes pitting, uneven and tarnish of the deck, as well as the occurrence of nail ridges, furrows, turbidity, hypertrophy, free ends and nail bed stripping, and even the whole deck deformity or absence, etc., seriously affecting patients' social interaction and mental health. Pathologically, telangiectasis is associated with the superficial and middle layers of the dermis. Previous treatment of psoriasis nail is mainly topical drugs (such as glucocorticoid, etc.), but due to its long disease period, topical drugs are difficult to transdermal absorption, and the curative effect of skin lesions is poor.
Pulsed dye laser (PDL) is effective for vasodilatory diseases, especially for the superficial to middle layers of the dermis
It has been reported that PDL is effective in the treatment of psoriasis vulgis by blocking the nutrient supply vessels of the lesions, improving the surrounding microenvironment, reducing the number of cytotoxic T cells and helper T cells in the dermis, and promoting the normalization of epidermal proliferation and differentiation.
Halometasone is a potent halogen - containing topical glucocorticoid. Have stronger fight inflammation, fight allergy, contractive hemal, reduce hemal to connect the action of permeability and fight hyperplasia Vaseline belongs to a kind of mineral wax, without irritant, not easy to deteriorate, can let skin surface form a protective film when used on the skin, let the moisture of the skin be evaporated not easily, have better protect wet effect.

Outcome Measures

Primary Outcome Measures

NAPSI score [Change from Baseline to 1 year]
Nail matrix score: according to the proportion of nail matrix damage (puncture, meniscus with all white and red spots, and nail fragmentation) to the nail matrix content, 0 means no, 1 means 1/4 nail, 2 means 2/4 nail, 3 means cumulative 3/4 nail, and 4 means total nail. Nail bed score: the nail bed damage (nail dissection, puncture hemorrhage, hyperkeratosis under the nail, salmon spot) is graded according to the proportion of the nail bed. 0 means no, 1 means 1/4 nail, 2 means 2/4 nail, 3 means cumulative 3/4 nail, and 4 means total nail. Single nail score is the sum of nail matrix score and nail bed score (0-8 points), The final score is the sum of all single nail scores (0-80), and the nail score can be conducted at any time as required.

Secondary Outcome Measures

VAS Pain Assessment [Change from Baseline to 6 months]
VAS Pain Assessment，Immediately after Treatment
