ABSTRACT

Objective To study the effect of red and blue light combined with erythromycin gel in ther treatment of acne.Methods 100 acne patients were selected,they were randomly divided into two groups according to the digital table,50 cases in each group.The observation group was treated with red and blue light combined with erythromycin gel,the control group was treated with erythromycin gel alone.The improvement of the quality of life and treatment effect were compared.Results The difference of total effective rate between the observation group and the control group was statistically significant (90％ vs.70％,x2 =6.250,P =0.023).After treatment,the self-perception [(14.28 ± 1.05) points vs.(14.28 ± 1.05) points,t =6.009,P =0.007],acne distribution [(14.00 ± 2.25) points vs.(14.69 ± 2.05) points,t =6.028,P =0.006],emotional function [(13.50 ± 2.20) points vs.(13.27 ± 2.01) points,t =7.827,P =0.001],social function [(11.03 ± 1.84) points vs.(11.30 ± 1.79) points,t =5.892,P =0.012],overall cognition [(13.33 ± 1.05)points vs.(13.00 ± 1.23) points,t =5.772,P =0.015] had statistically significant differences between the two groups (all P ＜ 0.05).The incidence rate of adverse reactions between the two groups had statistically significant difference (4％ vs.24％,x2 =8.306,P =0.008).Conclusion Red and blue light combined with erythromycin gel in the treatment of acne has good effect,less complications,it can significantly improve quality of life of patients.
