Clinical Observation on External Application of Liangxue Chushi Zhiyang Powder in Treating Facial Dermatitis
Objective To observe the clinical efficacy of external application of Liangxue Chushi Zhiyang Powder(composed of Isatidis Folium,Chrysanthemi Flos,Sophorae Flavescentis Radix,Schizonepetae Spica,and Zanthoxyli Pericarpium,etc.)in the treatment of facial dermatitis,and to analyze its effect on skin barrier function of the patients.Methods Seventy-two patients with facial dermatitis were randomly divided into the control group and the observation group,with 36 cases in each group.The control group was treated with Butyl Flufenamic Ointment for external use and Ebastine Tablets orally,while the observation group was given cold and wet compress of Liangxue Chushi Zhiyang Powder on the basis of treatment for the control group.The course of treatment of both groups covered three weeks.Before and after the treatment,the changes of subjective and objective symptom scores as well as skin barrier function indicators of the two groups were observed.After treatment,the clinical efficacy and incidence of adverse reactions of the two groups were assessed.Results(1)After three weeks of treatment,the total effective rate of the observation group was 75.00%(27/36),and that of the control group was 47.22%(17/36);the intergroup comparison showed that the therapeutic efficacy of the observation group was significantly superior to that of the control group(χ2=5.844,P＜0.05).(2)After treatment,the scores of objective symptoms such as erythema,inflammatory papules,desquamation,swelling,and lesion area in the two groups were significantly decreased when compared with those before treatment(P＜0.05),and the decrease of the scores of erythema,inflammatory papules and lesion area in the observation group was significantly superior to that in the control group(P＜0.05).The differences in the scores of desquamation and swelling between the two groups were not statistically significant(P＞0.05).(3)After treatment,the scores of subjective symptoms such as itching,burning,stabbing pain,dryness/tightness of the skin in the two groups were significantly decreased when compared with those before treatment(P＜0.05),and the decrease of the scores of each subjective symptom in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the skin barrier function indicators such as trans-epidermal water loss(TEWL)and skin pH value of the two groups were significantly lowered(P＜0.05),and stratum corneum hydration(SCH)and sebum(SEB)content were significantly increased when compared with those before treatment(P＜0.05).The decrease of TEWL and pH value as well as the increase of SCH and SEB content in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment,no serious adverse reactions occurred in the two groups of patients.The incidence of adverse reactions in the observation group was 8.33%(3/36),and that in the control group was 5.66%(2/36),and the difference was not statistically significant(χ2=0.215,P＞0.05).Conclusion The cold and wet compress of Liangxue Chushi Zhiyang Powder exerts certain efficacy in the treatment of facial dermatitis,which is effective on markedly relieving the subjective and objective symptoms of the patients,and improving the skin barrier function,with few and mild adverse reaction.
