原发性失眠中医证候与多导睡眠图相关性研究

Correlated Study in Chinese Medicine Syndromes of Primary Insomnia and Polysonmography

目的：总结阴虚火旺和肝郁化火两型失眠的睡眠图特点。方法：观测阴虚火旺型、肝郁化火型失眠患者及健康者的多导睡眠图，总结各证型的睡眠图特点。结果：阴虚火旺和肝郁化火患者睡眠效率低，在睡眠各期的时间均比正常时间短（P〈0．05），两组患者的慢波睡眠减少，睡眠表浅，阴虚火旺组S1期所占比例较肝郁化火组高，而s2期比例则较肝郁化火组低（P〈0．05）。结论：阴虚火旺组临床表现以入睡困难为主，肝郁化火组以睡眠表浅、易醒为主要，进而利于临床辨证及治疗。

Objective： To summarize the hypnogram characteristics of two types of insomnia, fire excess from yin deficiency and pathogenic fire de rived from stagnation of liverqi. Methods： Polysomnography of insomnia patients and healthy subjects within two types of insomnia were observed, and each syndrome type of hypnogram characteristics was summarized. Results： Patients with fire excess from yin deficiency and pathogenic fire de rived from stagnation of liverqi were of low sleep efficiency, time of each sleeping stage was shorter than normal time （P〈0.05）, slow wave sleep of two groups decreased with shallow sleep, phase S1 proportion of fire excess from yin deficiency was higher than that of pathogenic fire derived from stagnation of liverqi, while phaseS2 proportion was lower （P〈0.05）. Conclusion： Clinical feature of fire excess from yin deficiency is mainly diffi culty in falling asleep, and pathogenic fire derived from stagnation of liverqi is chiefly shallow and festless sleep, which is helpful for clinical differ entiation of syndrome and treatment.
