Figure 2. — Comparison of T lymphocyte subsets at different time-points between the two groups. (A) T lymphocyte subsets including CD3⁺, CD4⁺ and CD8⁺ cells were analyzed by flow cytometry. Percentages of CD3⁺ and CD4⁺ cells, and the CD4⁺/CD8⁺ ratios significantly decreased at T_1–4 in the two groups compared with the baseline value at T₀ and significantly increased at T_1–4 in the dexmedetomidine group compared with the control group. *P<0.05 vs. T0, ^#P<0.05 vs. group C. (B) Representative flow cytometry contour plots of CD3⁺ T cells in CD45⁺ cells of group C and group D at T_0–4. D, dexmedetomidine; C, control; T₀, 30 min before induction; T₁, 1 h after induction; T₂, end of the operation; T₃, 24 h after operation; T₄, 48 h after operation.
