OBJECTIVE To explore the effect and mechanisms of baicalein on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced experimental colitis in mice.METHODS BALB/c mice were randomly placed into three groups (n=10):normal control group,TNBS group,and TNBS+baicalein (20 mg· kg-1,once per day) group.Mouse colitis was induced by intrarectal injection of TNBS.Baicalein was administered by oral gavage two days prior to TNBS treatment and until the end of the study (a total of 9 d).The colon length was measured before HE staining was performed for histological damage assessment.The remaining colon pieces were collected to measure the content of tumor necrosis factor-α(TNF-α).Lipopolysaccharide (LPS)-stimulated RAW264.7 mouse macrophage was used as a cell model to determine the content of nitric oxide (NO) in cell culture medium,the mRNA levels of TNF-α,interleukin-6(IL-6),IL-1β,inducible nitric oxide synthase(iNOS),cyclooxygenase 2(COX-2) and monocyte chemoattractant protein-1 (MCP-1),and the protein expression of phosphatidylinositol 3-kinase/protein kinase B/nuclear factor-κB (PI3K/AKT/NF-κB) pathway.RESULTS Baicalein significantly attenuated TNBS-induced colon shortening and histological injury (P＜0.05),which was correlated with the decline in the content of TNF-α in the colon.According to the jn vivo results,baicalein exposure down-regulated the secretion of NO and the mRNA expression of pro-inflammatory mediators (iNOS,COX-2,MCP-1,TNF-α,IL-1β and IL-6) in LPS-stimulated RAW264.7 cells (P＜0.05,P＜0.01).Additionally,the phosphorylation/activation of LPS-stimulated PI3K/AKT/NF-κB pathway was inhibited by baicalein treatment.CONCLUSION The beneficial effect of baicalein in TNBS-induced experimental colitis may be due to PI3K/AKT/NF-κB signaling inhibition.

Effective cost control and structure optimization of medical consumables in public hospitals can facilitate a shift from extensive cost control to scientific and refine management.On the premise of ensuring medical quality,reducing the burden of patients'diagnosis and treatment and meeting the actual needs of hospital management,this approach aims to realize valuable healthcare outcomes.This study was conducted in a tertiary hospital,which balanced both the medical and economic val-ue of medical consumables.Using an integrated approach to specialty capacity building and disease structure optimization,the hospital restructured the use of medical consumables in Transcatheter Arterial Embolization(TAE)procedures.It developed standardized pathways and usage protocols tailored to specific diseases and surgical requirements.A targeted consumable usage policy framework was introduced,comprising"one department,one policy;one surgery type,one policy;and one consumable,one policy."This included initiatives such as validating the use of drug-loaded embolic microspheres,conducting multi-depart-mental review meetings,strictly regulating indications for these microspheres,limiting personnel involvement,and negotiating re-duced pricing on imported microspheres.Following implementation,the average case-mix index(CMI)for discharged patients undergoing TAE increased from 2.23 to 2.34(P＜0.001),while the average per-case cost of consumables decreased from 19 600 to 15 600(P＜0.001).These measures offer valuable decision-making and operational reference for hospitals nation-wide,supporting efficient,quality-focused consumables management.

Objective In the context of expanding in size and improving the quality of medical consumables,the"one product,one policy"approach has brought challenges to the management of consumables in public hospitals.This study investi-gated the potential management problems in the process of centralized procurement with volume of medical consumables in a pub-lic tertiary hospital in Guangdong Province,and accordingly worked out the corresponding management countermeasures and then assessed their implementation effects.Methods The fishbone diagrams was applied to systematically analyze the potential prob-lems in the implementation process of centralized procurement with volume of medical consumables.Targeted measures were worked out from May to July 2023 in the hospital.The time series data of centralized procurement of coronary stents,pacemak-ers,tubular/end-to-end anastomoses,and spinal products from December 2022 to December 2023 were analyzed.Changes in the monthly implementation rate and contract completion volume pre-and post-intervention were measured to evaluate the effectiveness of the intervention.Results The fishbone diagrams analysis revealed that the primary factors impeding procurement implementa-tion were internal system flaws,personnel management inadequacy,supply issues,and an absence of an information system.Post-intervention,the monthly implementation rate(t=-4.19,P＜0.05)and contract completion(t=-2.38,P＜0.05)significantly improved.Conclusion The implementation of intervention management for centralized procurement with volume of medical consumables can effectively promote the related implementation effect in the department.In the context of centralized pro-curement,clinical and health management personnel need to bolster their professionalism to ensure the procurement management efficiency and quality.It is crucial to deepen policy understanding and implementation,enhance production and distribution process supervision and disciplinary mechanisms,ensure multi-departmental coordination for supply security,and improve hospi-tal information systems and procurement platforms.
