国内外大量的基础实验及临床研究都证实远端负极电流的直流电场及脉冲电场等均有促进周围神经再生的作用，认为其可加速Schwann细胞的游走、爬行及生长发育，诱导神经纤维的生长；电刺激还能促使神经外膜毛细血管数量增多，扩张血管，改善神经损伤段缺血状态，并加速Wallerian变性及崩解组织的清除，为Schwann细胞发育和髓鞘化过程提供充足的能量与物质，同时为神经轴突的再生提供良好的内环境；在神经断端出现瘢痕或神经瘤时，电刺激可增加神经纤维穿越瘢痕的能力。

NRP2-1和NRP2-2在发情期二花脸卵巢、子宫、输卵管中的表达量均大于杜洛克相应组织的表达量，推测NRP2表达水平高可能有利于提高产仔数，但两品种间表达差异不明显，推测NRP2影响产仔数的关键阶段可能不是猪的发情期；另外，NRP2 是神经轴突介导因子的受体，这些神经轴突转导的信号往往有级联放大的功能，虽然NRP2-1和NRP2-2在二花脸和杜洛克卵巢、子宫、输卵管中的表达差异不大，但二花脸有可能通过神经系统转导信号的级联放大最终引起一些效应激素或蛋白的急剧增加，从而提高排卵率或产仔数。
