针刺孔

After placement in a stereotaxic apparatus, A microdialysis probe was implanted in the left hippocampal CA1 region (2 mm to the left and 3.6 mm posterior to the bregma and 2 mm below the cortical surface).

切开头皮，用微型颅钻分别在左右海马CA1区(前囟3.6mm和中线左、右旁开3mm)打开一直径约2mm的圆孔，将微透析探针刺入左侧海马CA1区2mm，用乳酸钠林格氏液以2.5μl/min的速度持续灌注，稳定60min待脑电图波形稳定后收集脑组织透析液，间隔时间为10min，直至再灌注后2h。

Results the safe angle range for needling yamen (gv 15) were: 16.27±7.68～29.46±7.23 degrees for males and 18.46±4.81—33.61±7.83 degrees for females; the danger angle of upward oblique insertion was negatively correlated with the extension of bowing and raising the head, that is, the larger the angle of backward raising the head, the smaller the range of danger angle of needling into the great occipited foramen.

结果：得出哑门穴安全针刺角度，男性为16.27±7.68～29.46±7.32度，女性18.46±4.81～33.61±7.83度。且向上斜刺的危险角度范围与头颅俯仰程度呈负相关，即头颅后仰角度越大，刺入枕骨大孔的危险角度范围越小。
