| Items | Time After Injection | |||
| 0 h | 3 h | 8 h | 24 h | |
| Control group | 1 | 1.345 | 1.573 | 1.245 |
| Methylprednisolone group | 0.996 | 0.991 | 1.2 | 1.13 |
Abbreviations: Grb2, growth factor receptor-bound protein 2; iTRAQ, Isobaric tags for relative and absolute quantitation .
Note: iTRAQ have no specific values of expression of Grb2 in this study, so we assume C - 0 = 1.
