ABSTRACT
OBJECTIVE@#To compare the clinical therapeutic effect of fire needling stripping after local anesthesia, simple fire needling and liquid nitrogen cryotherapy on verruca vulgaris.@*METHODS@#A total of 900 patients with verruca vulgaris were randomized into a fire needling stripping group (300 cases, 2 cases dropped off), a fire needling group (300 cases, 4 cases dropped off) and a liquid nitrogen cryotherapy group (300 cases, 5 cases dropped off). After local anesthesia of compound lidocaine cream, fire needling therapy was adopted, and the necrotic tissue of verruca was stripped in the fire needling stripping group. Simple fire needling therapy was adopted in the fire needling group, without local anesthesia and stripping. Liquid nitrogen cryotherapy was adopted in the liquid nitrogen cryotherapy group. The treatment was given once a week, and totally 3 weeks were required in the 3 groups. The skin lesion scores of number, area, thickness, color, pruritus, isomorphism and the level of T lymphocyte (CD@*RESULTS@#Compared before treatment, the skin lesion scores were decreased (@*CONCLUSION@#Fire needling stripping after local anesthesia can effectively treat the verruca vulgaris, improve the skin lesion and immunity, its therapeutic effect is superior to simple fire needling and liquid nitrogen cryotherapy.

Objective To evaluate the clinical efficacy and safety about carbon dioxide fractional laser combined with liquid nitrogen cryotherapy for flat warts.Methods Eighty-three patients with flat warts were divided into 2 groups according to the treatment method,42 patients in treatment group were treated by carbon dioxide fractional laser combined with liquid nitrogen cryotherapy,41 patients in control group were treated by liquid nitrogen cryotherapy alone.As a period for 10 days,2 groups were given 2 periods of treatment.The therapeutic effect,recurrence rate and adverse reaction were compared between 2 groups.Results The cure rates of 1-period and 2-period in treatment group were significantly higher than those in control group [73.81％(31/42) vs.46.34％(19/41) and 97.62％(41/42) vs.75.61％(31/41)],the recurrence rate and incidence of adverse reaction in treatment group were significantly lower than those in control group [2.44％(1/41) vs.19.35％(6/31) and 9.52％(4/42) vs.31.71％(13/41)],there were statistical differences (P ＜ 0.05 or ＜ 0.01).Conclusion Carbon dioxide fractional laser combined with liquid nitrogen cryotherapy for fiat warts is a safe and effective treatment with low recurrence rate.
