OBJECTIVE To investigate the improvement effects and mechanism of Zhichi suanzaoren decoction （ZSD） on hippocampal oxidative stress injury in hippocampal neurons of mice with perimenopausal insomnia. METHODS The potential targets of active ingredients in ZSD were predicted using TCMSP and TCMIP databases； the targets related to insomnia were searched through GeneCards， OMIM and DisGeNET databases； protein-protein interaction network of intersecting targets of ZSD ingredients and insomnia was constructed； Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were conducted on key targets. Sixty mice were divided into sham operation group， model group， ZSD low-， medium-， and high-dose groups （11， 22， and 33 g/kg）， and eszopiclone group （positive control， 1 mg/kg）. Except for sham operation group， the perimenopausal insomnia model was constructed by ovariectomy （OVX） in the other groups. After successful modeling， mice in each group were gavaged with normal saline or the corresponding drug solution， once a day， for three consecutive weeks. The sleep status of mice was evaluated through the pentobarbital sodium sleep synergy experiment， and the pathological changes of hippocampal neurons and the expressions of related genes and proteins in mice were observed by HE staining， immunohistochemistry staining， immunofluorescence staining， transcriptome sequencing technology and Western blot. RESULTS The results of network pharmacology showed that there were 296 intersection targets between ZSD and perimenopausal insomnia. Protein kinase B1 （Akt1） was a key target for treating insomnia with ZSD. After administration of ZSD， the sleep latency of mice was shortened， the sleep duration was prolonged significantly， and the mean optical density value of neuron-specific nuclear protein in the hippocampal CA1 region was significantly increased （P＜0.01）. Additionally， hippocampal neuron damage in OVX mice was significantly alleviated. The results of transcriptome sequencing showed that ZSD significantly upregulated the transcriptional levels of Nfe2l2 gene in hippocampal tissue of OVX mice （P＜0.05）. After administration of ZSD， protein expressions of nuclear factor E2 related factor 2 （Nrf2） and heme oxygenase-1 （HO-1） in hippocampal tissue of OVX mice， as well as the phosphorylated Akt level， were increased significantly （P＜0.01）. CONCLUSIONS ZSD can ameliorate hippocampal oxidative stress injury of hippocampal neurons in perimenopausal insomnia mice by activating the Akt/Nrf2/HO-1 signaling pathway.

OBJECTIVES: To investigate the therapeutic effect of the natural compound niranthin on Crohn's disease-like colitis in mice and explore the underlying molecular mechanisms. METHODS: In a mouse model of colitis induced by 2,4,6-trinitro-benzenesulfonic acid (TNBS), the therapeutic effect of niranthin was evaluated by observing the changes in body weight, disease activity index (DAI), and colon length of the mice. The levels of inflammatory cytokines (IL-6, IL-1β, TNF-α, IL-17A and IL-10) in the intestinal mucosal tissue were detected using ELISA and quantitative real-time PCR (qRT-PCR). TUNEL staining and Western blotting were used to assess intestinal epithelial cell apoptosis and the expressions of Bcl-2 and Bax. The expression levels of tight junction proteins (ZO-1 and claudin-1) and the activation of the p38/JNK signaling pathway were investigated using Western blotting, and diprovocim intervention experiments were conducted to explore the molecular regulatory mechanism of niranthin. RESULTS: Niranthin treatment significantly increased body weight of TNBS-treated mice, lowered the DAI and histological inflammation scores, and increased colon length of the mice. The niranthin-treated mouse models showed obviously reduced protein and mRNA levels of IL-6, IL-1β, IL-17A, and TNF-α and upregulated expression of IL-10 in the colon tissue. TUNEL staining and Western blotting demonstrated that niranthin significantly inhibited intestinal epithelial cell apoptosis and activated the anti-apoptotic pathway in the mouse models. Niranthin treatment obviously upregulated the expression levels of ZO-1 and claudin-1 and downregulated the phosphorylation levels of p38 and JNK in the colon tissues of the mice. Diprovocim intervention obviously attenuated the inactivation of the p38/JNK signaling pathway induced by niranthin in the mouse models. CONCLUSIONS Niranthin ameliorates TNBS-induced Crohn's disease-like colitis in mice by inhibiting intestinal epithelial cell apoptosis and protecting the integrity of the intestinal barrier via regulating the activation of the p38/JNK signaling pathway.

Salmonellosis represents a global epidemic, and the emergence of extensively drug-resistant (XDR) Salmonella and its sustained transmission worldwide constitutes a significant public health concern. Flagellum-mediated motility serves as a crucial virulence trait of Salmonella that guides the pathogen toward the epithelial surface, enhancing gut colonization. Artemisia argyit essential oil, a traditional herb extract, demonstrates efficacy in treating inflammation-related symptoms and diseases; however, its effects on flagellum assembly and expression mechanisms in anti-Salmonella activity remain inadequately explored. This study aimed to elucidate the mechanism by which Artemisia argyit essential oil addresses Salmonella infections. Network pharmacological analysis revealed that Traditional Chinese Medicine (TCM) Artemisia argyit exhibited anti-Salmonella infection potential and inhibited flagellum-dependent motility. The application of Artemisia argyit essential oil induced notable motility defects through the downregulation of flagellar and fimbriae expression. Moreover, it significantly reduced Salmonella-infected cell damage by interfering with flagellum-mediated Salmonella colonization. In vivo studies demonstrated that Artemisia argyit essential oil administration effectively alleviated Salmonella infection symptoms by reducing bacterial loads, inhibiting interleukin-1 beta (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α) production, and diminishing pathological injury. Gas chromatography-mass spectrometry (GC-MS) analysis identified forty-three compounds in Artemisia argyit essential oil, with their corresponding targets and active ingredients predicted. Investigation of an in vivo model of Salmonella infection using the active ingredient demonstrated that alpha-cedrene ameliorated Salmonella infection. These findings suggest the potential application of Artemisia argyit essential oil in controlling Salmonella, the predominant food-borne pathogen.

Objective:To investigate the correlations between physical, psychological and social frailty in elderly patients with multimorbidity.Methods:This study utilized a mixed method. A questionnaire survey was conducted from February to June 2024, among elderly patients with multimorbidity attending 4 primary health care centers in urban Beijing selected by the convenience sampling method. The FRAIL Frailty Assessment Scale, WHO-5 Index of Well-Being Scale, and HALFT Scale were used to assess the patients′ physical, psychological, and social frailty, respectively. Spearman correlation analysis was used to analyze the correlation between different dimensions of frailty in elderly with multimorbidity. Logistic regression model was used to analyze the factors influencing physical, psychological and social frailty. The elderly with multimorbidity who were assessed to have at least 1 or more types of frailty in the quantitative study were selected for in-depth interviews in the form of online and offline combination. The topics of in-depth interview included the real experience of the different dimensions of frailty, the possible causes and the difficulties caused. The sample size was determined according to the principle of information saturation. Thematic analysis was used to summarize, code and analyze the interview data.Results:A total of 919 participants were included in the quantitative study, with a mean age of (74.09±6.03) years, 329(35.80%) were males and 590(64.20%) were females. The prevalence of physical, psychological, and social frailty was 17.85%(164/919), 21.44%(197/919), 11.21%(103/919), respectively. A total of 21 participants were included in the qualitative study, with a mean age (76.90±5.13)years, 5(23.81%) males and 16(76.19%) females. Spearman correlation analysis showed that physical and psychological frailty were moderately correlated ( r=0.311, P<0.001), psychological and social frailty were weakly correlated ( r=0.218, P<0.001), and physical and social frailty were weakly correlated ( r=0.267, P<0.001). Logistic regression analysis showed that the age, the number of multimorbidities, the psychological frailty and social frailty were the influencing factors for physical frailty (all P<0.05). The gender, number of multimorbidity, type of medication taken, physical frailty and social frailty were influencing factors of psychological frailty (all P<0.05). And age, number of multimorbidities, physical frailty and psychological frailty were influencing factors of social frailty (all P<0.05). A total of 3 themes were extracted through in-depth interviews, namely, "physical and psychological frailty are interrelated""physical and social frailty are interrelated", and "psychological and social frailty are interrelated". Conclusions:The physical, psychological, and social frailty in elderly patients with multimorbidity interacts with each other. Whereas the number of multimorbidities is a common risk factor for all three.
