Relationship between serum IL-1β and insomnia and liver depression in patients with perimenopausal non-organic sleep disorder

The aim of the study was to detect the expression of interleukin-1β (IL-1β) in serum of patients with perimenopausal non-organic sleep disorder (PNSD) and to study the relationship between IL-1β and the severity of insomnia and liver depression, so as to benefit the prevention of PNSD. A total of 268 cases of perimenopausal patients from the Department of Traditional Chinese Medicine of Fujian Provincial Hospital and the Department of Traditional Chinese Medicine of Jinshan Branch of Fujian Provincial Hospital were selected from March 2014 to June 2017. Among them, 182 patients developed non-organic insomnia (observation group). The remaining 86 patients were included in the control group. Serum levels of IL-1β were measured by enzyme-linked immunosorbent assay (ELISA). Scores of liver depression were determined and graded. Pittsburgh Sleep Quality Index (PSQI) was used to assess the severity of insomnia. Spearman's correlation analysis was used to analyze the correlation between PSQI, IL-1β and liver depression grade. Scores of liver depression in the observation group were significantly higher than those in control group (p<0.05). In the observation group, and PSQI scores in patients with different grades of liver depression are significantly different (p<0.05). Average level of IL-1β in the observation group was significantly higher than that in control group (p<0.05). With the increase of liver depression grade, the expression level of IL-1β was also increased (p<0.05). Spearman's correlation analysis showed that PSQI was positively correlated with liver depression score, and the level of IL-1β was positively correlated with the liver depression grade in patients with PNSD. (r=0.724, p=0.012; r=0.765, p=0.008). Expression of IL-1β in women with PNSD is significantly upregulated, and different degrees of liver depression also exist. Higher expression level of IL-1β is accompanied by more serious liver depression and higher degree of insomnia.
