Abstract: OBJECTIVE To observe the effect of combined use of catgut implantation at acupoint and traditional Chinese drugs and western drugs on the recurrent attacks chronic uveitis patients' CD3⁺， CD4⁺，CD8⁺ and CD4⁺ /CD8⁺. METHODS 20 cases chronic uveitis patients were randomly put into two even groups: the treatment group combined use catgut implantation at acupoint and traditional Chinese drugs and western drugs， and the contrast group use traditional Chinese drugs and western drugs. Then the changes of CD3⁺， CD4⁺， CD8⁺ cell and CD4⁺ /CD8⁺ of the two groups were tested. RESULTS Both the two groups have significant changes on TcellCD3⁺(P<0.01)， and the two groups have no significant differences(P>0.05). Both the two groups have significant changes on ThcellCD4⁺(P<0.01)， and the treatment group are better than the contrast group(P<0.01). Both the two groups have significant changes on TscellCD8⁺(P<0.01)， and the treatment group are better than the contrast group(P<0.01). Both the two groups have significant changes on CD4⁺ /CD8⁺(P<0.05)， and the contrast group have significant changes on CD4⁺ /CD8⁺(P<0.05). CONCLUSION Catgut implantation at acupoint can improve the chronic uveitis patients'T-lymphocyte subpopulation， and furthermore improve the function of immune system.
