Objective To explore the potential mechanism of Polygonum cuspidatum in alleviating silicosis using network pharmacology, molecular docking, and experimental validation. Methods i) The targets of active components of Polygonum cuspidatum and silicosis-related targets were retrieved from multiple databases. The overlapping targets were imported into Venny2.1.0 and STRING platforms. "Polygonum cuspidatum-active components-potential therapeutic targets for silicosis" network was constructed and core targets of Polygonum cuspidatum that can alleviate silicosis were identified using the Cytoscape3.10.2 software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using the DAVID database, and molecular docking was conducted with AutoDock software. ii) Human embryonic lung fibroblast MRC-5 cells were divided into three groups. Cells in the control group were cultured in high-glucose Dulbecco's modified Eagle's medium containing 10.00% (V/V)fetal bovine serum. Cells in the silica group were treated with silica suspension at a final concentration of 150 μg·cm² (equivalent to 75 mg/L) for 48 hours. Cells in the silica + β-sitosterol group were first treated with silica suspension for 24 hours, then were cultured in medium containing β-sitosterol at a mass concentration of 50 μg/L for another 24 hours. Immunofluorescence assay and Western blotting were used to detect the effects of β-sitosterol, a core component of Polygonum cuspidatum, on the expression of phosphorylated protein kinase B (p-AKT), B-cell lymphoma-2 (BCL-2), and α-smooth muscle actin (α-SMA) in cells. Results i) A total of ten main active components of Polygonum cuspidatum, 840 targets of the active components, and 231 potential therapeutic targets for silicosis were screened through retrieval. A total of 10 core therapeutic targets were further screened, including tumor protein p53, serine/threonine protein kinase B1 (AKT1), heat shock protein 90-α, interleukin (IL)-6 , tumor necrosis factor, Src tyrosine kinase, estrogen receptor 1, epidermal growth factor receptor, BCL-2, and IL-1β. KEGG enrichment analysis yielded 178 related target pathways, among which, the phosphatidylinositol 3-kinase-protein kinase B (PI3K/AKT) signaling pathway was most relevant to silicosis. Molecular docking results showed that the top five compounds of Polygonum cuspidatum with high degree centrality, including quercetin, luteolin, physovenine, rhein, and β-sitosterol, had strong binding affinities with core targets. Among them, β-sitosterol, a key component of Polygonum cuspidatum, ranked high in binding affinity to all core targets. Molecular docking visualization indicated that β-sitosterol ranked high in binding affinitiy with the core target proteins AKT1 and BCL-2. ii) Both immunofluorescence and Western blotting results showed that, the relative expression of p-AKT, BCL-2, and α-SMA proteins increased in MRC-5 cells of the silica group compared with the control group (all P<0.05), except for p-AKT detected by Western blotting. Compared with the silica group, the relative expression levels of p-AKT, BCL-2, and α-SMA proteins in the silica+β-sitosterol group decreased (all P<0.05). Conclusion β-sitosterol, the core component of Polygonum cuspidatum, may alleviate silicosis fibrosis via the PI3K/AKT signaling pathway.

Objective:To develop the Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy and evaluate its reliability and validity.Methods:Based on the theory of unpleasant symptoms, a preliminary version of the Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy was developed through literature analysis, semi-structured interviews, and the Delphi method. After revising certain items in the pre-survey, convenience sampling was used to select patients who underwent bladder instillation chemotherapy in the Department of Urology Surgery of three ClassⅢ Grade A hospitals in Yunnan Province from January to July 2024 as research subjects to test the reliability and validity of the scale.Results:A total of 168 questionnaires were distributed, and 162 valid questionnaires were collected, with a valid response rate of 96.429% (162/168). The Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy covered two areas of symptom severity and symptom distress, comprising five dimensions and 27 items. The Cronbach's α coefficient for the total scale was 0.953, and the split-half reliability coefficient was 0.806. Exploratory factor analysis revealed that the four common factors for symptom severity contributed to 73.196% of the cumulative variance, while the single common factor for symptom distress accounted for 68.285% of the cumulative variance. Confirmatory factor analysis revealed that all indicators met the fit criteria, indicating that the model possessed good goodness-of-fit. The content validity index at the scale level was 0.940, while the content validity index at the item level ranged from 0.833 to 1.000.Conclusions:The Symptom Assessment Scale for Patients Undergoing Bladder Irrigation Chemotherapy developed in this study demonstrates good reliability and validity, and is suitable for evaluating symptoms in patients undergoing bladder infusion chemotherapy.
