大椎穴拔罐前后对健康成人左肺俞及其旁开非经穴的氧分压变化的影响

目的通过观察拔罐疗法对穴位局部组织氧分压改变的影响,探讨其对能量代谢影响的机理。方法该试验运用自制复合式氧分压传感器及智能型四通道氧分压测试仪进行动态连续实时监测,观察健康人体大椎穴拔罐前后对左肺俞及其旁开非经穴的氧分压变化的影响。结果左肺俞的氧分压从起罐5 min开始至20 min各时间点与基础5 min、拔罐5 min比较均具有统计学意义(P<0.05),旁开非经穴的氧分压在各时间点均无统计学差异(P>0.05);在基础5 min与拔罐5 min时,左肺俞的氧分压与旁开非经穴比较均有统计学差异(P<0.05)。结论拔罐大椎穴5 min后,左肺俞处组织随时间变化氧分压下降,起罐20 min时略有回升。大椎穴拔罐可能致使左肺俞处组织耗氧增多,能量代谢加快。旁开非经穴处组织,氧分压变化随时间变化无明显差异;生理状态下,左肺俞的含氧量可能高于旁开非经穴。拔罐后左肺俞处能量代谢更明显。

Effect of Cupping at Dazhui(GV14)on the Partial Pressure of Oxygen of Left Feishu(BL13)and Its Adjacent Non-acupoint in Healthy Adults

Objective To observe the effect of cupping therapy on the partial pressure of oxygen in the local tissues of acupoint,and to explore the mechanism of its effect on energy metabolism.Method The self-made complex transducer of oxygen partial pressure and intelligent four-channel oxygen partial pressure detector were adopted for successive and dynamic monitoring,to observe the effect of cupping at Dazhui(GV14) on the partial pressure of oxygen of left Feishu(BL13) and its adjacent non-acupoint in healthy human subjects.Result The oxygen partial pressure of the left Feishu at the time points from 5 min to 20 min after cupping were different from that at the initial 5 min and the 5 min of cupping;the oxygen partial pressure of the adjacent non-acupoint had no significant differences at various time points(P>0.05).During the initial 5 min and the 5 min of cupping,the oxygen partial pressure of the left Feishu was significantly different from that of the adjacent non-acupoint(P<0.05).Conclusion After 5-minute cupping at Dazhui,the oxygen partial pressure in the tissues of left Feishu decreased with time,and slightly increased 20 min after removal of the cup.Cupping at Dazhui may cause increased oxygen consumption and accelerated energy metabolism at the left Feishu.While the oxygen partial pressure at the adjacent non-acupoint did not show significant change with time.It is possible that the oxygen content of the left Feishu is higher than that of the adjacent non-acupoint.It showed significant energy metabolism at the Left Feishu after cupping.
