RESUMEN
Objective To observe the clinical efficacy of modified Shehuang Ointment(mainly composed of Cnidii Fructus,Phellodendri Chinensis Cortex,and Zanthoxyli Pericarpium)for the treatment of facial seborrheic dermatitis(SD).Methods Seventy-two patients with facial SD were randomly divided into observation group and control group,with 36 patients in each group.Both groups of patients were given oral use of Acrivastine Capsules and Vitamin B6 Tablets,and additionally,the observation group was given topical application of modified Shehuang Ointment and the control group was given topical application of 2%Ketoconazole cream.The course of treatment covered 4 weeks.The changes of clinical symptom scores and dermatology life quality index(DLQI)scores in the two groups were observed before and after treatment,and the clinical efficacy and safety of the two groups were also evaluated.Results(1)After 4 weeks of treatment,the total effective rate of the observation group was 88.89%(32/36),and that of the control group was 72.22%(26/36).The intergroup comparison showed that the efficacy of the observation group was significantly superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the clinical symptom scores of erythema,scales,grease,rash area,itchiness and other clinical symptoms of the patients in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the clinical symptom scores of the observation group were significantly lower than those of the control group,the differences being statistically significant(P＜0.05).(3)After treatment,the DLQI scores of patients in the two groups were significantly lower than those before treatment(P＜0.05),and the DLQI scores in the observation group were significantly lower than those in the control group after treatment,the difference being statistically significant(P＜0.05).(4)During the treatment period,no significant adverse reactions occurred in the two groups of patients,with high safety.Conclusion The conventional western medicine treatment combined with topical application of modified Shehuang Ointment exerts certain effect in the treatment of facial SD,which can effectively relieve the clinical symptoms and improve the quality of life of patients.
