针刺合谷穴对心脾两虚型不寐患者自主神功能的影响
Effect of Acupuncture at Hegu(LI4) on Autonomic Nerve Function in Patients with Insomnia Due to Heart-Spleen Deficiency

目的：通过针刺受试者左侧合谷穴，记录针刺不同时间节点的ANS功能指标，观察针刺左侧合谷穴对ANS功能的影响。方法：60例受试者随机分为合谷穴组和非经非穴组，每组各30例。观察两组在针刺前、针刺时、留针时、出针时、出针后5个时间点ANS功能指标变化。结果：两组针刺各时间点HRV、卧立位心率变化(30/15 ratio)、卧立位血压差等指标和针刺前相比，差异有统计学意义(P < 0.05)。合谷穴组针刺时间点HRV、卧立位心率变化(30/15 ratio)指标高于非经非穴组，卧立位血压差低于非经非穴组。结论：针刺心脾两虚型不寐患者左侧合谷穴可调节ANS张力，提升HRV指数，抑制SNS张力过高，增强PSNS张力，从而调整ANS均衡性，且有一定遗留效应。
Objective: By acupunculating the left Hegu point of the subjects, the ANS function indexes at different time points of acupuncture were recorded, and the influence of acupuncture on the ANS function was observed. Method: Sixty subjects were randomly divided into Hegu acupoint group and non-jingfei acupoint group, with 30 cases in each group. The changes of ANS function indexes were observed at 5 time points before acupuncture, during acupuncture, during needle retention, during needle withdrawal and after needle withdrawal. Result: HRV, heart rate change in lying position (30/15 ratio), blood pressure difference in lying position and other indexes at each time point of acupuncture between the two groups had statistical significance compared with before acupuncture (P < 0.05). HRV and heart rate change (30/15 ratio) at acupuncture time in Hegu point group were higher than those in non-Jingfei point group, and the difference of blood pressure in supine position was lower than that in non-Jingfei point group. Conclusion: Acupuncture at left Hegu point can adjust ANS tension, increase HRV index, inhibit excessive SNS tension, enhance PSNS tension, and thus adjust ANS balance, with certain residual effects.
