To evaluate effects of Aikeqing Capsule on T Lymphocyte Subsets in HIV Infectors.Methods:HIV Infectors included between Jan of 2008 and Jul of 2009 received Aikeqing Capsule and have T lymphocyte subsets detected at Month0, 1, 6, 12, 18, 24. Paired-Samples T test and one-way ANOVA were used in statistical analysis. Results:Comparing M6 with M0, CD3 increased significantly (P<0.01), while other changes were not significant: CD4 and CD8 increased, CD4/CD8 decreased (P>0.05). Decreases of CD3、CD4、CD8 between baseline and M12、M18、M24 were not different statistically(P>0.05). Changes of CD4/CD8 was significant only when using M12 as endpoint(P<0.01).Conclusion: Aikeqing Capsule can significantly increase CD3 levels in asymptomatic HIV-infectors after 3-month treatment, and stabilize CD3,CD4,CD8 levels. So Aikeqing Capsule has a definite slowing down effect for progression the infection.
