Objective To gain an in-depth understanding of the authentic experiences of impaired dignity among patients in the recovery phase of severe bums,thereby informing the development of targeted dignity intervention plans by clinical medical staff.Methods By purposive sampling,the study included 16 patients in the recovery phase of severe burns,admitted to the Burn and Plastic Surgery Rehabilitation Department of a tertiary hospital in Guangzhou between December 2023 and January 2024.Face-to-face,semi-structured in-depth interviews were conducted,and the themes were analyzed,summarized,and distilled by the Colaizzi 7-step analysis method.Results 3 themes were identified,including impairment of physical dignity(physical disfigurement,change in appearance,and limitations in autonomous activities),psychological dignity conflicts(negative emotional disturbances and positive adjustment for adaptation)and the aspiration for social dignity(desire for family understanding,social support,and the hope to return to a normal life).Conclusion Clinical nurses should value the dignity experience of patients in the recovery phase of severe burns and establish patient-dignity-centered intervention plans to facilitate their dignified and high-quality recovery to a normal life.

Autophagy is an important mechanism to maintain cellular function and metabolism,whereas ab-normal autophagy can cause the advent and worsening of various diseases.N6-Methyladenosine(m6A)RNA methylation is a reversible RNA modification,which is regulated by m6A methyltransferase,m6A demethylase and m6A-binding protein.Studies have shown that autophagy-related genes promote or attenuate autophagy level dependent on the regulation of m6A,and then participate in the process of diseases.This paper reviews the progress of m6A modification regulatory enzymes and their binding proteins in regulating cell autophagy to provide reference for future researches.

Objective:To explore the effective components and potential mechanisms of Xiefei Lishui Prescription in the treatment of heart failure.Methods:Ultra high-performance liquid chromatography tandem four stage rod time of flight mass spectrometry (UPLC-Q-TOF-MS) technology was used to analyze and identify the active components of Xiefei Lishui Prescription. Drug targets were predicted through the Swiss Target Prediction database, and disease targets were collected from Gene Cards, Dis GENET, and TTD databases. The intersection of drug targets and disease targets was screened using a STRING database for protein interaction to identify core targets. The core targets were included in the DAVID database for GO enrichment and KEGG analysis. Finally, molecular docking validation was performed between the drug components and the corresponding core targets.Results:The results identified 10 active components of Xiefei Lishui Prescription, and 8 potential active components were screened using network pharmacology for the treatment of heart failure with Xiefei Lishui Prescription, corresponding to 160 related action targets. A total of 1 305 disease-related targets were collected, and a total of 51 targets ad 17 core targets were included in the string database for protein interaction analysis. GO functional enrichment and KEGG analysis indicated that the mechanism of Xiefei Lishui Prescription in treating heart failure may be related to pathways such as protein binding, ATP binding, and negative regulation of the VEGF signaling pathway and T cell receptor pathway during apoptosis. The molecular docking results showed that baicalin exhibited good binding activity with ESR1, sorghum isoflavones with ESR1, and quercetin with AKT1, EGFR, IL2, and ABCB1.Conclusion:Xiefei Lishui Prescription may exert therapeutic effects on heart failure through multiple pathways by targeting ESR1, AKT1, EGFR, and other targets.

Myocardial infarction is the most common cause of heart failure,and myocardial remodeling can occur after infarction,thus contributing to the progression of heart failure.The occurrence of post-infarction ventricular remode-ling is closely related to m6A methylation.m6A methylation is a reversible and highly dynamic process.This process is mainly mediated by m6A methylation positive and negative regulatory enzymes and is involved in the occurrence of post-in-farction myocardial remodeling through mechanisms such as cellular autophagy.This article mainly reviews relevant litera-ture in recent years.Firstly,a brief introduction is given to m6A methylation,followed by an introduction to the role of m6A methylase in regulating myocardial remodeling.Finally,a summary analysis is conducted on the mechanism of m6A methylation in regulating myocardial remodeling from the perspectives of autophagy,inflammation,cell apoptosis,calcium ion homeostasis,extracellular matrix remodeling,and ferroptosis.The feasibility of using m6A methylation serological de-tection as a diagnostic tool for myocardial remodeling after myocardial infarction is discussed,in order to provide reference for related research.
