Effects of different intensities of RTLI on the early apoptotic ratio of the endothelial cells. The cell early apoptotic ratio was detected by flow cytometry. (A) Comparison of differences in the early apoptotic ratio of endothelial cells between groups N and H. *P < 0.05. (B) Comparison of differences in the early apoptotic ratio of endothelial cells among groups H, S3qod and R3qod. (C) Comparison of differences in the early apoptotic ratio of endothelial cells among groups H, S3qd and R3qd. (D) Comparison of differences in the early apoptotic ratio of the endothelial cells among groups H, S6qd and R6qd. *P < 0.05 compared with group H; ΔP < 0.05 compared with group S6qd. Data are presented as the mean ± SD, n = 10, 9, 7, 7, 8, 7, 8, and 9 in groups N, H, S3qod, R3qod, S3qd, R3qd, S6qd, and R6qd, respectively
