Objective: To explore the mechanism of action of Zangjiangzhi capsule (ZJZC) in treating hyperlipidemia (HLP). Methods: The components of ZJZC were analyzed and identified using ultra-high performance liquid chromatography with Q-Exactive Orbitrap tandem mass spectrometry (UHPLC-Q-Exactive-Orbitrap-MS/MS). Network pharmacology analysis was used to explore the mechanism of action of ZJZC in HLP treatment. The SwissTargetPrediction database was used to predict compound targets, and GeneCards, DisGeNet, OMIM, and DRUGBANK databases were used to identify HLP-related targets. Protein–protein interaction diagrams were constructed using the STRING database. The targets were subjected to gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The “herb-ingredient-target” network was visualized using Cytoscape. Preliminary validation was performed using molecular docking and enzyme-linked immunosorbent assay. Results: Ninety compounds were identified in ZJZC, including 34 flavonoids, 12 phenols, 10 terpenoids, 10 alkaloids, 8 organic acids, 8 anthraquinones, and 9 other compounds. In total, 904 targets were identified for these compounds. Among them, 158 targets intersected with the HLP target network. Network pharmacology analysis showed that MAPK1, PPAR-α, RXRA, HSP90AA1, PIK3R1, AKT1, PIK3CA, IL6, TNF, and ESR1 are the key targets of action. KEGG enrichment analysis identified 164 pathways. Among these, the AGE-RAGE signaling pathway in diabetic complications, lipid and atherosclerosis pathways, regulation of lipids in adipocytes, and insulin resistance are related to HLP. Molecular docking showed good affinity between the key targets and ingredients. Further, ZJZC treatment in mice resulted in lower expression of MAPK1 protein and increased expression of PPAR-α protein, which have been shown to be strongly associated with HLP. Conclusions This study showed that ZJZC contains various active ingredients and can modulate multiple targets and pathways associated with HLP, providing evidence at the molecular level for its clinical application in the treatment of HLP.

Operation management is an important tool to promote the high-quality development of public hospitals in China.Since the founding of New China,based on China's economic and social development and medical and health system reform,the evolution of operation management of public hospitals in China can be divided into four stages,the system building stage(1949-1978),the liberalization and revitalization stage(1979-1996),the operation mechanism reform stage(1997-2020),and the new stage of high-quality development(2021 present).The development trend of public hospital operation management in future should deepen the public welfare-oriented public hospital operation management,explore the value-oriented medical operation management model based on high-quality development and the refined operation and management model of public hospitals,so as to promote the high-quality development of public hospitals in China.

Objective To compare the differences in the average transaction costs per-referral patients under different models of Integrated Delivery Systems(IDS).Methods Using a typical case sampling method,it selected referred patients from three IDS models:the county medical alliance in D City(Qinghai Province),the urban medical consortium in J District(Zhengzhou City,Henan Province),and the health management coalition in N County(Shandong Province).Structured questionnaires collected demographics,average transaction costs per-referral and cost perceptions.t-tests and ANOVA assessed cost differences;generalized linear regression identified influencing factors.Results Among 915 patients,the average transaction costs per-referral were 1 035.05 yuan(county alliance),195.31 yuan(urban consortium),and 700.97 yuan(health management coalition),with statistically significant differences(P＜0.05).The urban consortium exhibited lower time costs and specialized input costs.Key influencing factors included older age(county alliance),education level,employment status,and referral travel time(urban consortium),as well as urban-rural disparities(health management coalition).Patients'cost perceptions significantly differed across models(P＜0.05).Conclusion The urban medical consortium demonstrated the lowest patient the average transaction costs,highlighting its institutional advantage in minimizing financial burdens.

Objective The study aims to elucidate the inhibitory effects of curcumin on the proliferation of colon cancer RKO cells,focusing on the regulatory mechanisms of tripartite motif-containing protein 2(TRIM2)expression and the mammalian target of rapamycin(mTOR)signaling pathway.Methods Experimental concentrations of curcumin were determined by calculating the half maximal inhibitory concentration(IC50)value.Quantitative polymerase chain reaction(qPCR)was utilized to assess the level of TRIM2 expression in RKO and fetal human colon(FHC)cells.Western blotting analysis was conducted to investigate the level of TRIM2 expression and mTOR pathway-related proteins in curcumin-treated RKO cells.The impact of curcumin treatment,TRIM2-knockingdown,and mTOR signaling pathway on proliferation in RKO cells was quantified using the cell counting kit-8(CCK8)assay.Results The expression of TRIM2 was found to be elevated in RKO cells as determined by qPCR,compared to FHC cells.Curcumin suppressed the level of TRIM2 expression,and subsequent knockdown of TRIM2 resulted in decreased expression of mTOR-related proteins in RKO cells.Both curcumin and TRIM2-knockdown demonstrated significant inhibition of proliferation in RKO cells,with reversion upon activation of mTOR signaling pathway.Conclusion The study unveils the inhibitory effects of curcumin on RKO cells proliferation through modulation of TRIM2 expression and the mTOR signaling pathway.

Objective To analyze the correlation between the Patellotrochlear index at different knee flexion angles and recurrent patellar dislocation,and to find the optimal knee flexion angle and the best diagnostic cut-off value for predicting recurrent patellar dislocation.Methods A total of 35 patients clinically diagnosed with recurrent patellar dislocation(study group)were selected.The lengths of the central sagittal plane of the patellar cartilage and the corresponding femoral trochlear cartilage were measured at knee flexion angles ranging from 0° to 70°,in 10° increments.The Patellotrochlear index was calculated and compared with the MRI data from 55 healthy volunteers(control group).Results The Patellotrochlear index in the study group and the control group showed a positive correlation with the knee flexion angle(r=0.935 and 0.909,P＜0.001).Statistically significant differences were found between the two groups at knee flexion angles of 0°,10°,20°,30°,and 40°(t=7.480,5.742,5.200,3.558,4.271,P＜0.05).The predictive efficacy of the Patellotrochlear index for recurrent patellar dislocation varied at different knee flexion angles,with the area under the curve(AUC)and the best diagnostic cut-off values of 0.891,0.834,0.778,0.710,0.741 and 0.195,0.323,0.486,0.606,0.712,respectively.Conclusion There are significant differences in the Patellotrochlear index at different knee flexion angles.A knee flexion angle of 0° is the optimal knee flexion angle for the Patellotrochlear index to predict recurrent patellar dislocation,with a recommended best diagnostic cut-off value of 0.195.
