The celiotomy was performed in group A, vagotomy in group B, vagotomy adding pyloroplasty in group C, proximal subtotal gastrectomy in group D, and the electrodes were embedded at the gastric corpus and antrum in all groups.

A组单纯开腹，于胃体和胃窦置入电极，B组行迷走神经切断术，C组行迷走神经切断加幽门成形术，D组行近端胃大部分切除术。

The gastric motility is mainly controlled by CNS ( central nervous system) at the level of brainstem, through para-sympathetic and sympathetic ways. The pre-parasympathetic fibers concerned with gastrointestinal functions are mostly originated from DMV ( dorsal motor nucleus of the vagus).

脑干是调节胃运动的基本中枢，迷走神经背核（dorsal motor nucleus of the vagus，DMV）是支配胃肠道副交感神经的主要中枢核团，经迷走神经传出，对胃肠活动进行调节。

The glucose sensitiveness of the LHA neurons which responded to the gastric vagal nerve stimulation in model group decreased ( P < 0.01) but increased in VMN neurons ( P < 0.01).

模型大鼠中对胃迷走神经刺激有反应的LHA神经元的血糖敏感率降低，而那些对胃迷走神经刺激有反应的VMN神经元的血糖敏感率增加（P<0.01）。
