ObjectiveTo investigate the potential mechanisms of Zingiberis Rhizoma in treating inflammatory bowel disease (IBD) by integrating network pharmacology with in vitro and in vivo experiments. MethodsTraditional Chinese Medicine Systems Pharmacology Database And Analysis Platform (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID) Database were used to obtain the active component targets of Zingiberis Rhizoma. GeneCards was used to obtain the IBD targets. DAVID was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses on core targets. Cytoscape 3.10.2 was used to establish the "active component-disease target-signaling pathway" interaction network. Mice were randomly assigned to control, model, and Zingiberis Rhizoma (400 mg·kg-1) groups. An IBD model was induced via dextran sulfate sodium (DSS). The colonic tissue was collected post-treatment to assess histology, expression of Ly6C+ monocytes/macrophages, and mRNA levels of Toll-like receptor 4 (TLR4), and inflammatory cytokines. The effect of Zingiberis Rhizoma aqueous extract on RAW264.7 cell viability was evaluated. Furthermore, the effects of the extract at 100, 10, and 1 mg·L-1 on LPS-induced differentiation of RAW264.7 cells into Ly6Chi monocytes/macrophages, mRNA levels of TLR4 and inflammatory cytokines, and protein levels of factors in the TLR4/mitogen-activated protein kinase (MAPK) signaling pathway. ResultsA total of 241 targets were identified for Zingiberis Rhizoma and 6 787 for IBD, with 122 shared targets among Zingiberis Rhizoma, ulcerative colitis (UC), and Crohn's disease (CD). The enrichment analyses yielded 297 GO terms and 88 KEGG pathways. Associations were noted between Zingiberis Rhizoma's active component targets and IBD targets. In vivo experiments: Compared with the control group, the model group showed decreased body weight and disease activity index (DAI)(P<0.01), shortened colon length, damaged mucosal epithelium with inflammatory cell infiltration, raised pathological scores (P<0.05), increased Ly6Chi and Ly6Clo monocytes/macrophages (P<0.05), and up-regulated mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.05) and protein levels of TLR4, phosphorylated extracellular signal-regulated protein kinase 1/2 (p-ERK1/2), and phosphorylated p38 MAPK (p-p38 MAPK) (P<0.05). Zingiberis Rhizoma intervention reversed these changes and reduced Ly6Chi monocytes/macrophages (P<0.01). In vitro experiments: compared with the control, LPS increased the proportion and number of Ly6Chi monocytes/macrophages and mRNA levels of TLR4, TNF-α, IL-1β, and IL-6 (P<0.01) and enhanced the expression of TLR4, p-ERK1/2, and p-p38 MAPK (P<0.05). Zingiberis Rhizoma reduced Ly6Chi monocytes/macrophages (P<0.05), down-regulated the mRNA levels of inflammatory cytokines (P<0.05), and suppressed the TLR4/MAPK pathway (P<0.05). ConclusionZingiberis Rhizoma alleviates IBD by suppressing the TLR4/ERK/p38 MAPK signaling pathway and reducing inflammatory cytokine levels in Ly6Chi monocytes/macrophages.

Myopia is a significant global health issue,and its exact causes are still not fully understood,leaving a lack of effective and propaqable treatment options.The prevalence of myopia among children and adolescents in China remains high,posing challenges for prevention and control efforts.According to the"theory of imbalance of essence and tendon",an imbalance in the essential elements and tendons can impede the passage of eye essence and blood,resulting in delayed expansion and contraction of the eye meridians and tendons,leading to blurred vision.Modern research indicates that during the development of myopia,there are notable changes in the microstructure,activation range,and signaling of various brain regions,providing a biological basis for the"brain-eye"mechanism.Moreover,abnormal activity in the brain nucleus contributes to alterations in choroid blood flow and the impairment of eye muscle regulation,thereby accelerating the progression of myopia,this phenomenon represents the manifestation of the brain-eye imbalance.Consequently,strategies for myopia prevention and control should prioritize nourishing kidney essence,replenishing brain marrow,promoting liver and blood health,and softening the meridians.These measures aim to optimize the functioning of the brain and eyes,maintain the flexibility of eye tendons,enhance eye regulation,sustain the strength of eye tendons,and delay the advancement of eye axis growth and myopia.By enriching the scientific understanding of the appropriate application of traditional Chinese medicine techniques to prevent and control myopia through the brain,this research provides valuable insights for future explorations in this field.

Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective:To explore the mediating effect of rumination between self-perceived burden (SPB) and stigma in stroke patients, so as to provide theoretical basis for the development of targeted nursing interventions in clinical practice.Methods:In September 2022, cluster sampling was used to select 1 126 stroke patients admitted to Department of Neurology of five ClassⅢ Grade A hospitals in Henan Province as subjects. General Information Questionnaire, Self-Perceived Burden Scale (SPBS), Stroke Stigma Scale (SSS), and Chinese Version of Event Related Rumination Inventory (C-ERRI) were used to investigate stroke patients. Pearson correlation analysis was used to explore the correlation between SPB, rumination, and stigma. AMOS 28.0 software was used to establish the structural equation model, and Bootstrap method was used to test the mediating effect.Results:A total of 1 126 questionnaires were distributed, and 1 026 valid questionnaires were collected, with a valid response rate of 91.12% (1 026/1 126). SPBS score of 1 026 stroke patients was (28.68±8.32), the SSS score was (40.53±9.48) and the C-ERRI score was (25.43±12.62). Pearson correlation analysis showed that SPB in stroke patients was positively correlated with stigma and rumination ( P<0.01), and rumination was positively correlated with stigma ( P<0.01). Bootstrap mediating effect test showed that rumination partially mediated the relationship between SPB and stigma in stroke patients, accounting for 55.15% of the total effect. Conclusions:SPB of stroke patients both directly affect stigma and indirectly affect stigma through rumination. Clinical nursing workers should promptly evaluate patients' SPB, pay attention to the mediating role of rumination, develop effective psychological intervention programs, implement personalized and targeted nursing measures, relieve patients' stigma, and improve treatment and rehabilitation compliance.

Objectives:
. The annual prevalence of chronic rhinosinusitis (CRS) is increasing, and the lack of effective treatments imposes a substantial burden on both patients and society. The formation of nasal polyps in patients with CRS is closely related to tissue remodeling, which is largely driven by the epithelial-mesenchymal transition (EMT). MicroRNA (miRNA) plays a pivotal role in the pathogenesis of numerous diseases through the miRNA-mRNA regulatory network; however, the specific mechanism of the miRNAs involved in the formation of nasal polyps remains unclear.
Methods:
. The expression of EMT markers and Smad3 were detected using western blots, quantitative real-time polymerase chain reaction, and immunohistochemical and immunofluorescence staining. Differentially expressed genes in nasal polyps and normal tissues were screened through the Gene Expression Omnibus database. To predict the target genes of miR-145-5p, three different miRNA target prediction databases were used. The migratory ability of cells was evaluated using cell migration assay and wound healing assays.
Results:
. miR-145-5p was associated with the EMT process and was significantly downregulated in nasal polyp tissues. In vitro experiments revealed that the downregulation of miR-145-5p promoted EMT. Conversely, increasing miR-145-5p levels reversed the EMT induced by transforming growth factor-β1. Bioinformatics analysis suggested that miR-145-5p targets Smad3. Subsequent experiments confirmed that miR-145-5p inhibits Smad3 expression.
Conclusion
. Overall, miR-145-5p is a promising target to inhibit nasal polyp formation, and the findings of this study provide a theoretical basis for nanoparticle-mediated miR-145-5p delivery for the treatment of nasal polyps.

Objective:To investigate the metabolic profile of fatty acids in elderly frail patients, and its value as a biomarker of frailty.Methods:Forty-nine older adults were recruited, of whom 19 were non-frail while 15 were in the pre-frail or frail phase.Targeted metabolomics was used to detect the serum levels of fatty acids, concerning 38 short-, medium-and long-chain fatty acids.Results:Metabolomics indicated elevated levels of 9 long-chain fatty acids in the serum of the elderly frail patients, with a 1.056-fold increase in the risk of fatigue for every 1 unit increase in the level of HOMO-γ-linolenic acid( OR=2.056, P=0.016). No metabolic differences were found between the pre-frail and non-frail groups.Three and seven long-chain fatty acids were negatively correlated with the grip strength and gait speed, respectively.The γ-linolenic acid was positively correlated with body mass index(BMI), percent body fat, visceral fat area and other indicators reflecting adipose tissue.However, no correlation was found between skeletal muscle, laboratory indicators or fatty acids.Five metabolic pathways were correlated with frailty, namely fatty acid biosynthesis, fatty acid metabolism, fatty acid elongation in mitochondria, linoleic acid metabolism and α-linolenic acid metabolism. Conclusions:Nine unsaturated fatty acids, including HOMO-γ-linolenic acid and γ-linolenic acid, may be potential biomarkers of frailty in the elderly.However, the value of fatty acid metabolomics for identifying pre-frail elderly people needs to be further investigated.
