| Group | n | 12 h | 1 day | 2 days | 3 days | 7 days |
| Normal control | 8 | 1.03±1.32 | - | - | - | - |
| Surgical control | 8 | 1.01±0.90 | - | - | - | - |
| Mild injury | 15 | 1.21±1.21 | 1.13±0.27 | 8.19±2.13 | 12.18±1.96 | 7.56±2.74 |
| Moderate injury | 13 | 1.97±0.88 | 6.21±2.37 | 12.15±2.19 | 18.44±3.97a | 8.93±2.51 |
| Severe injury | 10 | 1.13±1.12 | 8.23±1.81 | 15.35±3.11 | 27.18±5.05b | 9.12±3.04 |
Significant differences (P<0.05) were identified in the cell apoptosis index at 3 days subsequent to trauma between athe moderate injury group and the mild injury group (P=0.035) and bthe severe injury group and the moderate injury group (P=0.042).
