Figure 3. The serum lymphocyte and lymphocyte subsets in the two groups. (A) The serum lymphocyte was detected before the treatment and 3 mo after treatment both in the treatment group and the control group. Compared with before treatment, all p > 0.05 by the Student's T test. (B) The serum lymphocyte subsets, such as the serum T lymphocyte, B lymphocyte, CD4⁺ T lymphocyte and CD8⁺ T lymphocyte were detected by flow cytometry before and after treatment. Compared with before treatment, *p < 0.05, ** p < 0.01 by the Student's T test or the Wilcoxon test. (C) The serum CD4⁺/CD8⁺ in the two groups, compared with before treatment, **p < 0.01 by the Student's T test or the Wilcoxon test.
