Objective Explore the differences in the tranquilizing effects between Jiannao Bushen Wan (W) and Jiannao Bushen Oral Liquid (KFY), and predict their mechanisms of action for tranquilization. Methods A mouse model of insomnia was established by intraperitoneal injection of parachlorophenylalanine (PCPA). Different doses (0.225, 0.450, and 0.900 g·kg-1) of W and KFY were administered for intervention. The spontaneous activity of mice was assessed using the open field test, while sleep latency and sleep duration were observed through the pentobarbital sodium-induced sleep test. Histopathological changes in the hippocampus were examined using hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to detect the levels of 5- hydroxytryptamine (5-HT), norepinephrine (NE), dopamine (DA), γ-aminobutyric acid (GABA), interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in the brain. Western blotting was used to measure the protein expression of 5- hydroxytryptamine receptor 1A (5-HT1A) and γ-aminobutyric acid A receptor alpha 1 (GABRA1) in the hypothalamus, aiming to investigate their pharmacodynamic activities in improving insomnia-like behaviors, neuroinflammation, and regulating sleep-related neurotransmitters, as well as to predict their mechanisms of action. The comprehensive weight coefficient method and principal component analysis were applied to comprehensively evaluate the aforementioned pharmacodynamic indicators, comparing the differences in the tranquilizing effects between W and KFY. Results The results of the animal experiment showed that both W and KFY significantly reduced the movement distance, average speed, and grid-crossing count of mice in the open field test (P<0.05 and 0.01), decreased the sleep latency and increased the sleep duration in the pentobarbital sodium-induced sleep test (P<0.05 and 0.01). Furthermore, they ameliorated the pathological morphology of hippocampal neurons, significantly upregulated the levels of 5-HT and GABA in the whole brain (P<0.05, 0.01 and 0.001) and the expression of 5-HT1A and GABRA1 in the hypothalamus (P<0.05, 0.01 and 0.001), and significantly downregulated the levels of NE, DA, IL-6, IL-1β, and TNF-α in the whole brain (P<0.05, 0.01 and 0.001). The pharmacodynamic comparison results using the Comprehensive Weight Coefficient Method and Principal Component Analysis indicated that the efficacy of both W and KFY exhibited a dose-dependent enhancement. Moreover, at the same clinically equivalent dose, KFY demonstrated superior overall pharmacodynamic efficacy. Conclusion W and KFY can exert therapeutic effects on insomnia by ameliorating insomnia-like behaviors, regulating neurotransmitters, and inhibiting neuroinflammation, with KFY demonstrating superior efficacy.
