ObjectiveTo elucidate the potential mechanisms by which the classic prescription Anmeidan alleviates cognitive impairment in insomnia model rats through metabolic profiling. MethodsA total of 60 SD rats were randomly divided into six groups: blank group, model group, low-, medium-, and high-dose Anmeidan groups, and the Suvorexant group, with 10 rats in each group. Except for the blank group, the insomnia model was established in all other groups via intraperitoneal injection of para-chlorophenylalanine. The Suvorexant group was administered Suvorexant solution (30 mg·kg-1·d-1) by gavage, while the low-, medium-, and high-dose Anmeidan groups received Anmeidan decoction (4.55, 9.09, 18.18 g·kg-1·d-1) by gavage. The blank group received an equivalent volume of normal saline. The open field test was used to assess spatial exploration and anxiety/depressive-like behaviors in rats. Serum levels of epidermal growth factor (EGF), brain-derived neurotrophic factor (BDNF), and vasoactive intestinal peptide (VIP) were measured using enzyme-linked immunosorbent assay (ELISA). Untargeted metabolomics was employed to identify differential metabolites in rat serum, and systematic biological methods were applied to analyze the potential targets and pathways of Anmeidan. ResultsCompared to the blank group, the model group exhibited significant reductions in total distance traveled, average speed, number of entries into the central area, time spent in the central area, and frequency of upright events (P<0.01), along with significant decreases in VIP, EGF, and BDNF levels (P<0.05,P<0.01). A total of 100 differential metabolites were identified between the model and blank groups. Compared to the model group, the low-, medium-, and high-dose Anmeidan groups showed significant increases in total distance traveled, average speed, number of entries into the central area, time spent in the central area, and frequency of upright events (P<0.05,P<0.01), as well as a significant increase in VIP levels (P<0.05,P<0.01). Anmeidan significantly reversed abnormal changes in 67 metabolites compared to the model group. A combined analysis identified 134 potential targets of Anmeidan, with network topology analysis suggesting that Caspase-3, B-cell lymphoma 2 (Bcl-2), nuclear transcription factor-κB (NF-κB), interleukin-1β (IL-1β), interleukin-2 (IL-2), matrix metalloproteinase-9 (MMP-9), and Toll-like receptor 4 (TLR4), among others, may serve as key targets of Anmeidan. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed major enriched pathways, including the cyclic adenosine monophosphate (cAMP) signaling pathway, hypoxia inducible factor-1 (HIF-1) signaling pathway, and IL-17 signaling pathway. ConclusionThis study demonstrates that Anmeidan can recalibrate abnormal metabolic profiles in insomnia model rats to mitigate cognitive impairment, with its mechanisms of action potentially involving the regulation of immune-inflammatory responses, energy metabolism, and apoptosis-related pathways.

Objective :
To investigate the effects of immunoglobulin gene superfamily 10 (IGSF10) on prolifera- tion,migration and invasion of lung adenocarcinoma cells.
Methods :
ioinformatics was applied to study the ex- pression levels of IGSF10 in tumor tissues and normal tissues. Western blot and quantitative real-time PCR ( qPCR) were used to detect the expression level of IGSF10 in lung adenocarcinoma cell lines and normal lung epi- thelial cells.Knockdown of IGSF10,the effect of knockdown of IGSF10 on proliferation,migration and invasion of lung adenocarcinoma A549 cells was examined using cell counting kit-8 ( CCK-8) ,Transwell migration and inva- sion assay,scratch assay and plate cloning assay.The effects of knockdown of IGSF10 on the expression of invasion and migration-related genes in A549 cells were examined by Western blot and qPCR assays.
Results :
IGSF10 ex- pression in lung adenocarcinoma tissues was lower than that in normal tissues (P <0. 05) .IGSF10 expression in lung adenocarcinoma cell lines was lower than that in lung epithelial cells (P<0. 05) .Knockdown of IGSF10 pro- moted the ability of lung adenocarcinoma A549 cells to proliferate ,proliferation ,migration and invasion ( P < 0. 05) .Knockdown of IGSF10 promoted the expression of regulatory epithelial-mesenchymal transition marker Neu- ral-cadherin (N-cadherin) and key transcription factors Snail family transcriptional repressor 1 (Snail) and Snail family transcriptional repressor 2 (Slug) (P<0. 05) and inhibited the expression of Epithelial-cadherin (E-cad- herin) (P<0. 05) .
Conclusion
Knockdown of IGSF10 may promote proliferation,migration and invasion of lung adenocarcinoma cells through activation of Snail,Slug / E-cadherin signaling axis,and this result may provide a po- tential new target for clinical diagnosis and treatment of lung adenocarcinoma.
