The protection is partially due to the reduction of neural cell apoptosis.

结果：与对照组相比，脊髓损伤后促红细胞生成素1小时，6小时实验组神经运动功能明显改善，脊髓神经细胞凋亡指数均明显下降(P 0.01)；而术后24小时组与对照组相比，脊髓神经细胞凋亡指数的下降无统计学意义结论：早期应用外源性EPO对脊髓不完全损伤后引起的神经运动功能损害具有保护作用，此种保护作用可能与EPO能够减少神经细胞凋亡有关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
