AIM: To identify the primary active components and underlying mechanisms of Yijing Decoction(YJD)in treating early diabetic retinopathy(DR)based on liquid chromatography-mass spectrometry and network pharmacology.METHODS: Active components of YJD were characterized through LC-MS. Components with optimal ADME(absorption, distribution, metabolism, excretion)properties were selected as key bioactive candidates. Network pharmacology approaches were employed to predict YJD-DR therapeutic targets. Protein-protein interaction(PPI)networks, gene ontology(GO)enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis were subsequently conducted to predict core targets and networks. Critical targets and pathways were experimentally validated through Western blot.RESULTS: Ten core therapeutic targets were identified, including TNF, Alb, EGFR, STAT3, PTGS2, ESR1, PPAR, MMP9, TLR4, and MAPK. YJD was related to cancer-related signaling, fluid shear stress and atherosclerosis, and neurodegenerative diseases, encompassing key biological processes such as inflammatory response regulation, programmed cell death activation, and enhanced cell migration. Furthermore, Western blot analysis confirmed that YJD significantly inhibited high glucose-induced phosphorylation of STAT3(P-STAT3/STAT3)and ERK(P-ERK/ERK)in rat retinal microvascular endothelial cells.CONCLUSION: This study revealed YJD's pharmacodynamical basis and its multi-component, multi-target, and multi-paths pharmacology. YJD exerts therapeutic effects on DR by coordinately regulating critical signaling pathways and alleviating intraocular inflammation, thus preserving retinal vascular endothelial cells, maintaining blood-retinal barrier integrity, and facilitating retinal neurovascular repair.

Obesity usually exacerbates the immunosuppressive tumor microenvironment (ITME), hindering CD8+ T cell infiltration and function, which further represents a significant barrier to the efficacy of immunotherapy. Herein, a multifunctional liposomal system (CR-Lip) for encapsulating celastrol (CEL) was utilized to remodel obesity-related ITME and improve cancer immunotherapy, wherein Ginsenoside Rg3 (Rg3) was detected interspersed in the phospholipid bilayer and its glycosyl exposed on the surface of the liposome. CR-Lip had a relatively uniform size (116.5 nm), facilitating favorable tumor tissue accumulation through the interaction between Rg3 and glucose transporter 1 overexpressed in obese tumor cells. Upon reaching the tumor region, CR-Lip was found to induce the immunogenic cell death (ICD) of HFD tumor cells. Notably, the level of PHD3 in HFD tumor cells was effectively boosted by CR-Lip to effectively block metabolic reprogramming and increase the availability of major free fatty acids fuel sources. In vivo, experiments studies revealed that the easy-obtained nano platform stimulated enhanced the production of various cytokines in tumor tissues, DC maturation, CD8+ T-cell infiltration, and synergistic anticancer therapeutic potency with aPD-1 (tumor inhibition rate = 82.1%) towards obesity-related melanoma. Consequently, this study presented an efficacious approach to tumor immunotherapy in obese mice by encompassing tumor eradication, inducing ICD, and reprogramming metabolism. Furthermore, it offered a unique insight into a valuable attempt at the immunotherapy of obesity-associated related tumors.

Objective It developed and tested the reliability and validity of the Hospital Culture Perception and Experi-ence Scale for medical staff to provide a scientific tool for assessing medical staff's perceptions and experiences of hospital culture.Methods The scale was constructed with reference to the Dennison model of organisational culture and refined based on policy documents,literature and expert consultation.A hospital was selected to conduct the questionnaire survey.It used item analysis,factor analysis,and Cronbach's α to test scale reliability and validity.Results The total scale contains 43 entries in 4 subscales:institutional initiatives,practitioner perception,manage-ment training and mission commitment.Item analysis results showed that the scale had good differentiation;the Cronbach's αof the total scale was 0.992,and the Spearman-Brown was 0.979,with good reliability.Exploratory factor analysis results suggested that the institutional initiative,practitioner perception,and management training sub-scales had only 1 dimension,with a variance contribution rate of 77.12%,76.33%,and 85.75%,respectively.For the mission subscale,2 male factors were extracted,with a cumulative variance contribution rate of 91.34%.The factor loadings were all greater than 0.4.The validation factor analysis results shows that the model fit is good.The AVE of each subscale and dimension is greater than 0.5,and the CR is greater than 0.7,which indicates that the convergent validity is good.Conclusion The scale has good reliability and validity,and can be used to quantitatively as-sess the medical staff's perception and sense of experience of hospital culture.

Objective It developed a hospital culture awareness and experience scale for patients and their families and its reliability and validity were verified.The scale provides a tool for investigating patients'and families'experiences of hospital culture and promoting hospital culture building.Methods A scale that meets policy requirements and practice needs was designed with reference to a theoretical framework of hospital customers satisfaction index and it was refined through expert consultation.Patients and family members of a sample hospital were selected for the survey,and the reliability and validity of the scale were tested by item analysis,factor analysis and Cronbach's α.Results The scale contains 29 items in 3 dimensions of service perception,value recognition and cultural knowledge.Item analysis results showed that the scale had good differentiation.The Cronbach's αof the total scale was 0.975,and the Spearman-Brown was 0.934,with good reliability.Exploratory factor analysis extracted three male factors,with a cumulative variance contribution rate of 76.61%,and the factor loadings of each factor were all greater than 0.4.Validation factor analysis results suggests a better model fit.The CR is greater than 0.7 and the AVE of each dimension is greater than 0.5,which proves that convergent validity is good.Conclusion The scale has good reliability and validity,and can be used to quantitatively assess patients'and their families'sense of knowing and experiencing the hospital culture.It can provide scientific tool for evaluating the status of cultural leadership in helping public hospitals to develop high quality from the patient's perspective.
