Objective To explore the characteristics of sleep structure in chronic insomnia disorder(CID)with disharmony between heart and kidney pattern and liver qi stagnation pattern.Methods A total of 74 patients with CID who were treated in Tongde Hospital of Zhejiang Province from June 2021 to December 2022 were selected and divided into disharmony between heart and kidney group and liver qi stagnation group according to TCM syndrome differentiation types,with 37 cases in each group.Relevant parameters of both groups were collected and analyzed using polysomnography(PSG).Results The age of patients in disharmony between heart and kidney group was significantly higher than that in liver qi stagnation group(P<0.05).There were statistically significant differences in total sleep time,sleep efficiency,rapid eye movement sleep period,N1 stage and N3 stage between two groups(P<0.05).The results indicated that patients in disharmony between heart and kidney group had light sleep,low sleep efficiency and short total sleep time.Conclusion With the increase of age,most of the syndromes of CID patients are disharmony between heart and kidney pattern,and there are obvious differences between the two types of sleep structure.Patients with disharmony between heart and kidney pattern have light sleep and low efficiency,while patients with liver qi stagnation pattern have many dreams.

Objective To explore the characteristics of polysomnography(PSG)and the types of Chinese medicine symptoms in elderly patients with chronic insomnia disorder(CID),and to provide reference for the prevention and diagnosis of CID in the elderly.Methods A total of 205 patients diagnosed as CID with parallel PSG in the outpatient clinic of the Department of Neurology of Zhejiang Provincial Tongde Hospital from May 2022 to May 2023 were selected for the study,and were divided into the geriatric group(≥ 60 years old)and the non-geriatric group(＜60 years old)based on the difference in age,and statistics were collected on the distribution of Chinese medicine syndromes in the patients of the two groups,and the PSG was used to record and compare the structure and process of sleep in the patients of the two groups.parameters,and do correlation analysis.Results Total sleep time(TST),sleep efficiency TST time in bed(TIB),total duration of rapid eyes movement(REM)period,total duration of N2 period,total duration of N3 period,and REM% were lower in elderly patients than in the non-elderly group(P＜0.05).And the time to wakefulness after sleep,N1 latency,N2 latency,and N1% were statistically higher than those of the non-elderly group(P＜0.05).The TCM diagnosis of elderly patients with CID is more commonly characterized by cardiac and renal disorders.Conclusion There were differences in polysomnographic sleep testing between the elderly and non-elderly groups of patients with CID.Compared with the non-elderly group,the elderly group had shorter sleep duration,lower sleep efficiency,longer sleep latency,reduced total REM duration,and the most common clinical Chinese medicine diagnostic typology of cardiac and renal disorders.
