ABSTRACT

Objective To observe the clinical efficacy of modified Huanglian Qingxin Decoction for the treatment of recurrent oral ulcer. Methods Eighty recurrent oral ulcer patients were randomly divided into treatment group and control group by random number table method,40 cases in each group. The treatment group was given oral use of modified Huanglian Qingxin Decoction, and the control group was treated with Zinc Sulfate Tablets and Compound Vitamin B Tablets. Four weeks constituted one course of treatment. The scores of oral symptoms and signs of the two groups were observed before and after treatment,and the short-term effect and long-term effect of the two groups were evaluated after treatment. Results (1)After treatment for 5 days,ulcer area,ulcer pain, congestion area,exudation area,and sleep of the treatment group were much relieved (P < 0.01), and ulcer area,congestion area,and exudation area of the control group were improved (P < 0.05). The treatment group had better effect on improving ulcer area, ulcer pain, congestion area, exudation area, and sleep than the control group (P < 0.01). (2)After treatment for 5 days, the total short-term effective rate of the treatment group was 95.0%,and that of the control group was 72.5%,the difference being significant (P < 0.05).(3) Within one year after the suspension of treatment, total intermission period for ulcer attack in the two groups was prolonged (P < 0.05), and the amount of ulcer foci were much reduced (P < 0.05), the effect of the treatment group being superior to that of the control group(P < 0.05).(4)Within one year after the suspension of treatment,the total long-term effective rate of the treatment group was 70.0%,and that of the control group was 45.0%,the difference being significant (P<0.05). (5)During the treatment,the results of blood and urine routine examination,hepatic and renal function,and electrocardiography showed no abnormal changes. Conclusion Modified Huanglian Qingxin Decoction has better clinical efficacy for the treatment of recurrent oral ulcer than western medicine by relieving clinical symptoms and signs, prolonging the intermission period for ulcer attack, and reducing the total amount of ulcer foci.
