摘　　要：目的:观察健康人督脉线下深部组织氧分压及其在针刺过程中的变化,探讨与督脉路线相关组织的能量代谢特点。方法:沿督脉循行线取5个测试点,测试深度为皮下1.5cm,其中3个为经上穴位(中枢、至阳、命门),2个为经上非穴位点(第4胸椎棘突下、第12胸椎棘突下);在测试点左右两侧旁开1.5～2cm处各取1个非经对照点,从而形成5个横向测试水平。观察电针前、电针腰阳关穴时及电针后各测试点的氧分压变化情况,连续记录60min。结果:电针前,沿督脉循行线上测试点深部组织的氧分压与两侧非经对照部位比较差异有统计学意义(P<0.01)。电针腰阳关穴时,督脉线上测试点的氧分压与电针前比较明显降低(P<0.05)。电针后的氧分压与电针期间比较差异无统计学意义(P>0.05),与电针前比较差异有统计学意义(P<0.01)。左右两侧非经对照点的氧分压电针前、电针时及电针后相互比较差异均无统计学意义(P>0.05)。结论:电针前督脉循行线下深部组织中的能量代谢较其两侧非经对照部位旺盛,电针可以使沿经组织的能量代谢进一步增强,提示经脉可能是与物质、能量、信息的转换和传递相关的某种通道。Objective To observe changes of the partial oxygen pressure （PO2） of deep tissues along the Governor Vessel and during acupuncture, so as to probe into the characteristics of energy metabolism in the deep tissues along the meridian track. Methods Thirty-one healthy volunteers were enrolled in the present study. PO2 values in Zhongshu （GV 7）, Zhiyang （GV 9） and Mingmen （GV 4） of the Governor Vessel, and 2 non-acupoints （below the 4^th and the 12^th vertebrae respectively） were detected by using a three-channels needle-type sensor inserted into the tissues about 1.5 cm deep under the skin. The detection was conducted continuously for 60 minutes before, during and after electroacupuncture （EA, 2 HZ, 20 min） stimulation of Yaoyangguan （GV 3）. Results At normal state （before EA）, PO2 values were （10.98 ± 5.81） kPa in Governor Vessel （GV 4, GV 7 and GV 9）, being significantly higher than those [ （5.00 ±3.88） kPa, （4.74 ±4.23） kPa] of the left and the right control points separately. During acupuncture of GV3, PO2 value [（9.36 ± 5.99） kPa] in Governor Vessel decreased significantly in comparison with that of pre-EA; while those [（5.83 ± 4.75） kPa and （5.58 ± 5.28） kPa] in the left and the right control points had no obvious changes （P〉0.05）. And after acupuncture, the reading of PO2 was （8.62 ±5. 11） kPa along the Governor Vessel being comparable to that of EA-period, and those [（5.74±4.76） kPa and （5.61 ±5.45） kPa] in the left and the right control points still had no obvious changes. Conclusion PO2 in the deep tissues along the Governor Vessel is significantly higher than those of its bilateral control points, and decreases during and after EA, displaying a more vigorous energy metabolism in the deep tissues along the Governor Vessel in normal state, and up-regulation after EA.
