[Abstract]:Objective: To study the lymphocyte subsets, NK cell subsets and the changes of the secretory function, Th1, Th2 and Th17 subsets in the patients with chronic insomnia with yang-yang deficiency. The immune disorder status of the patients with yang-deficiency and chronic insomnia is analyzed from the angle of NK cells and T-cells, and the theoretical basis for the micro-differentiation of the chronic insomnia with yang-deficiency is provided. Methods: The study was a cross-sectional study, which was included in the patients with insomnia and the healthy physical examination of the patients with insomnia. According to the history of insomnia, the patients were divided into the chronic insomnia group and the normal control group, and the chronic insomnia group was divided into two groups of Yang-Yang, non-Yang, and Yang-Yang, respectively. The three sub-groups of the non-yang-yang mass group, the partial constitution group and the mild mass group, the general information, the physical constitution questionnaire of the traditional Chinese medicine and the Pittsburgh sleep scale were collected, and the lymphocyte subgroup detection, the NK cell killing function, the NK cell subpopulation and the particle-containing enzyme and the perforin were detected by flow cytometry. The subsets of Th1/ Th2/ Th17 cells and the level of TNF a, which were secreted by NK cells, were detected by the Elisa method. The general data, PSQI scale and the difference between the two sub-groups and the three sub-groups in the chronic insomnia group and the normal control group, the PSQI scale and the above-mentioned detection index were compared, and the correlation between the degree of yang-yang and the level of insomnia and the above-mentioned detection index was analyzed. Results:1. The lymphocyte subpopulation: the total number of lymphocytes, the number of NK cells, the total T-lymphocyte number, the inhibitory/ cytotoxic T-cell number and the total B-lymphocyte number of the chronic insomnia group (n = 59) decreased with the normal control group (n = 30). In the chronic insomnia group, the number of NK cells and the percentage of NK cells in the Yang-Yang mass group were lower than that of the non-Yang-Yang mass group, while the total number of T-lymphocytes, the percentage of total T-lymphocytes and the number of helper T-cells were higher than that of the non-Yang-Yang mass group. In the chronic insomnia group, the percentage of NK cells in the Yang-Yang mass group was lower than that in the mass group. The total number of T lymphocytes in the chronic insomnia group (r = 0.273), the total T-lymphocyte percentage (r = 0.37) was positively related to the degree of yang-yang, and the percentage of NK cells was negatively correlated with the degree of yang-yang (r =-0.273). The percentage of CD56 + CD16-NK cells in the chronic insomnia group (n = 32) was higher than that in the normal control group (n = 28). In the chronic insomnia group, the percentage of the particles of CD56 + CD16-NK cell subpopulation, the percentage of perforin and the fluorescence intensity of the granular enzyme were lower than that of the non-Yang-Yang mass group. In the chronic insomnia group, the percentage of the granular enzyme of CD56 + CD16-NK cell subpopulation of the Yang-Yang mass group was lower than that in the mass group. However, the fluorescence intensity of CD56 + CD16-NK cell subsets in the Yang-Yang mass group was lower than that of the non-yang-deficient group. The percentage of CD56 + CD16 + NK cells in the chronic insomnia group (n = 32) was lower than that in the normal control group (n = 28). In the chronic insomnia group, the percentage of CD56 + CD16 + NK cells, the percentage of granular enzyme, the percentage of perforin and the fluorescence intensity of the perforin were lower than that of the non-Yang-Yang mass group. In the chronic insomnia group, the percentage of the granular enzyme of CD56 + CD16 + NK cell subpopulation in the Yang-Yang mass group was lower than that of the non-yang-deficient group and the quality group decreased in the comparison among the three groups. The fluorescence intensity of CD56 + CD16 + NK cell subpopulation in the Yang-Yang mass group was lower than that in the mass group. CD56-CD16 + NK cells: the percentage of the particles of CD56-CD16 + NK cells in the chronic insomnia group (n = 32) was lower than that in the normal control group (n = 28), while the fluorescence intensity of the granular enzyme and the fluorescence intensity of the perforin were higher than that of the normal control group. In the chronic insomnia group, the percentage of the particles of the CD56-CD16 + NK cell subpopulation of the Yang-Yang mass group, the percentage of the perforin and the fluorescent intensity of the perforin were lower than that of the non-Yang-Yang mass group in the comparison among the two groups of the Yang-Yang mass group and the non-Yang-Yang mass group. In the chronic insomnia group, the percentage of CD56-CD16 + NK cell particles and the percentage of perforin in the Yang-Yang mass group were lower than that of the non-yang-deficient group. The fluorescence intensity of CD56-CD16 + NK cells in the Yang-Yang mass group was lower than that of the mild group. The percentage of CD56 + CD16 + NK cell subpopulation (r =-0.446), CD56 + CD16 + NK cell subpopulation particle enzyme percentage (r =-0.465), CD56 + CD16 + NK cell subpopulation particle enzyme fluorescence (r =-0.465), CD56 + CD16-NK cell subpopulation particle enzyme fluorescence (r =-0.504) were negatively correlated with the chronic insomnia group. The NK cell killing rate of the chronic insomnia group (n = 8), the TNF level of NK cell secretion, IFNy and the normal control group (n = 7) had no significant difference.4. The ratio of Th1/ Th2 and Th17 cells in chronic insomnia group (n = 58) was lower than that of normal control group (n = 22). In the chronic insomnia group, the percentage of Th1 cells, the percentage of Th2 cells and the percentage of Th17 cells in the Yang-Yang mass group were lower than that of the non-Yang-Yang mass group. in the chronic insomnia group, the percentage of the Th1 cells and the percentage of the Th2 cells in the Yang-Yang mass group were lower than that of the non-yang-deficient group, The percentage of Th17 cells in the Yang-Yang mass group was lower than that of the non-yang-deficient group. The percentage (r =-0.452), the percentage of Th2 cells (r =-0.39) and the percentage of Th17 cells (r =-0.387) in the chronic insomnia group were negatively correlated with the percentage of Th1 cells (r =-0.452), the percentage of Th2 cells (r =-0.39), and the percentage of Th17 cells (r =-0.387) (P0.05). Conclusion: The immune disorder caused by chronic insomnia is mainly characterized by the decrease of the number of NK cells and T cells and the shift of related functional subpopulations. It is suggested that chronic insomnia with yang-deficiency can be a type of immune function in chronic insomnia which is more likely to be affected by insomnia.
