Abstract:
ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）， network pharmacology and pharmacodynamics， to investigate the pharmacodynamic material basis and mechanism of Hei Xiaoyaosan in improving learning and memory ability of insomnia rats. MethodUPLC-Q-TOF-MS was used to characterize the chemical constituents of Hei Xiaoyaosan. Network pharmacology was applied to construct the network of active ingredients-intersecting targets-pathways， and molecular docking was performed on key ingredients and core targets. Sixty 8-week-old male SD rats were selected and randomly divided into blank group， model group， Hei Xiaoyaosan low， medium， and high dose groups（3.82， 7.65， 15.30 g·kg-1）， and zolpidem tartrate group（0.5 mg·kg-1）， with 10 rats in each group. Except for the blank group， the insomnia model was induced by intraperitoneal injection of p-chlorophenylalanine（PCPA） for 4 consecutive days. Rats in each dosing group were administered the corresponding dose by gavage， once a day for 14 consecutive days. Morris water maze test was utilized to assess the learning and memory ability of rats， transmission electron microscopy was employed to examine the ultrastructure of hippocampal synapses， enzyme-linked immunosorbent assay（ELISA） was conducted to analyze the levels of 5-hydroxytryptamine（5-HT）， interleukin-6（IL-6）， and tumor necrosis factor-α（TNF-α） in hippocampal tissues， and Western blot was performed to detect the expression levels of tumor suppressor protein p53（TP53）， rat sarcoma virus（RAS）， epidermal growth factor receptor（EGFR）， cyclic adenosine monophosphate（cAMP）-response element binding protein（CREB） binding protein（CREBBP）， glycogen synthase kinase-3β（GSK-3β）， protein kinase B1（Akt1）， nitric oxide synthase 1（NOS1）， phosphorylated（p）-Akt1， and p-GSK-3β in hippocampal tissues. Additionally， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was used to assess the mRNA expression levels of TP53， RAS， EGFR， CREBBP， GSK-3β， Akt1 and NOS1. ResultA total of 176 components were identified in Hei Xiaoyaosan， mainly flavonoids， triterpene saponins， phenylpropanoids and other compounds. Network pharmacological analysis revealed that TP53， V-Ha-Ras Harvey Rat sarcoma viral oncogene homolog（HRAS）， neuroblastoma sarcoma viral oncogene homolog（NRAS）， EGFR， CREBBP， GSK-3β， Akt1 and NOS1 were the key targets of Hei Xiaoyaosan in treating insomnia. The core targets were predominantly associated with cAMP， RAS， Ras-associated protein 1（Rap1）， advanced glycation end products（AGE）/receptor for AGE（RAGE）， and EGFR signaling pathways， and the key active ingredients of Hei Xiaoyaosan in treating insomnia were 8-shogaol， ligustilide F， 6-gingerol， levistilide A and senkyunolide E. Animal experiment results demonstrated that Hei Xiaoyaosan medium and high dose groups significantly increased body weight， shortened sleep latency and prolonged sleep duration in insomnia rats（P<0.01）， significantly decreased escape latency and increased platform crossing frequency（P<0.01）， and improved the pathological changes of hippocampal synaptic ultrastructure. Meanwhile， the two groups could significantly elevate 5-HT level， Akt1 mRNA expression， Akt1 and p-Akt1 protein expression（P<0.01）， reduce inflammatory factor levels（P<0.01）， and down-regulate protein expression levels of TP53， RAS， NOS1， EGFR， CREBBP， GSK-3β and p-GSK-3β（P<0.01）， as well as mRNA expression levels of TP53， RAS， NOS1， EGFR， CREBBP and GSK-3β in hippocampal tissues（P<0.01）. ConclusionThis study determined that the five key active ingredients（8-shogaol， ligustilide F， 6-gingerol， levistilide A and senkyunolide E） in Hei Xiaoyaosan may improve the learning and memory ability of insomnia rats by regulating signaling pathways such as cAMP， RAS， and EGFR， providing an important reference for its mechanism research and clinical application.
