ABSTRACT
Objective To evaluate the clinical efficacy of Yangyin Yiqi mixture and western medicine in the treatment of oral lichen planus(OLP)and its effect on the levels of interferon -γ(IFN -γ)and interleukine -10 (IL -10)in serum and saliva.Methods Sixty patients with OLP were randomly divided into control group(n =30) and treatment group(n =30).The control group was treated with triamcinolone acetonide and lidocaine,local injec-tion.The treatment group was treated with Yangyin Yiqi mixture on the basis of the control group.The treatment lasted two months.After treatment,the clinical efficacy,objective indicators score,levels of IFN -γand IL -10 in serum and saliva,adverse reactions were compared between the two groups.Results The overall response rate of the treatment group (86.67%)was significantly higher than that of the control group (63.33%)(χ2 =11.64,P <0.01).After treatment,the two groups'objective index score significantly reduced(t =8.52,12.51,all P <0.01),and the treat-ment group's objective indicators rating was significantly lower than the control group (t =4.38,P <0.05).After treatment,the levels of IFN -γin serum and saliva were (25.39 ±1.29)pg/mL and (12.76 ±1.28)pg/mL,which were significantly increased in the treatment group (t =10.35,8.15,all P <0.01),so did the control group (P <0.05).And the levels of IL -10 in serum and saliva were (27.54 ±1.82)pg/mL and (9.92 ±0.86)pg/mL,and the levels were significantly decreased in the two groups after treatment (t =8.76,9.39,all P <0.01,t =4.65,4.94,all P <0.05).And levels of IFN -γin serum and saliva of the treatment group were significantly higher than those of the control group (t =4.68,4.32,all P <0.05),and levels of IL -10 in serum and saliva of the treatment group were significantly lower than those of the control group (t =5.41,5.25,all P <0.05).During treatment,there were no sig-nificant adverse reactions.Conclusion Yangyin Yiqi mixture combined with western medicine has definitive clinical efficacy in the treatment of OLP.It can significantly increase the level of IFN -γand reduce the level of IL -10 in serum and saliva in patients,so provide theory value for treatment of OLP.
