Objective To investigate the effect of G9a histone methyltransferase inhibitor BIX01294 on the proliferation of vascular smooth muscle cell(VSMC)and its underlying mechanism.Methods Twelve SD rats were divided into the control group and the treatment group,with 6 rats in each group.The rats were anesthetized by intraperitoneal injection with sodium pentobarbital,then exposed the common carotid artery and the internal and external carotid artery after disinfection and skin preparation,ligated the distal end of the internal and external jugular veins,clamped the proximal end of the common carotid artery,cut the external carotid artery,inserted the balloon catheter,blocked the blood flow by compression,and ligated the proximal end of the external carotid artery after withdrawing the balloon.The common carotid artery clamping state of rats in the treatment group was maintained after withdrawing the balloon,then restored the blood flow after perfusion with 100 μmol/L BIX01294 solution for 30 seconds;rats in the control group were restored the blood flow after perfusion with PBS for 30 seconds.VSMC were divided into the normal group and the BIX01294 groups.Cells in the normal group were cultured in low glucose medium containing 2%fetal bovine serum,and cells in the BIX01294 groups were co-treated with 2.5,5.0,7.5 and 10.0 μmol/L BIX01294 on the basis of the normal group,respectively.CCK-8 assay and EDU assay were used to detect the cell activity and proliferative ability respectively,to screen appropriate concentration of BIX01294.The cell apoptosis was detected by TUNEL assay between the normal group and the BIX01294 group,and the control group and the treatment group.Western blot was used to detect the expression levels of autophagy-and apoptosis-related proteins in the normal group and BIX01294 group.Results Compared with 0 μmol/L,the activity and proliferative ability of VSMC decreased in a concentration-dependent manner after treatment with BIX01294 at different concentrations(P<0.05).Compared with the normal group,the apoptosis level of VSMC in the BIX01294 group was increased(P<0.05),the expression of VSMC autophagy-and apoptosis-related proteins of LC3Ⅰ/Ⅱ and Bax were up-regulated(P<0.05),and the expression of Bcl-2 and p62 proteins were down-regulated(P<0.05).In vivo test results showed that BIX01294 local perfusion aggravated the apoptosis of carotid VSMC.Conclusion BIX01294 activates VSMC autophagy and apoptosis and inhibits its proliferation.

Objective To develop a continuous care program for patients with cardiac implantable electronic devices(CIED)utilizing the Omaha system,and to assess its effectiveness.This study aims to provide a reference for the continuous care of patients with CIED.Methods Using the Omaha system as the theoretical framework,based on literature search and semi-structured interviews,a continuity of care program for CIED patients based on the Omaha system was constructed through 2 rounds of expert inquiry.Convenience sampling method was used to select CIED implant patients from the cardiovascular department of a tertiary hospital in Wuhan as the research subjects.61 patients admitted from April to June 2024 were assigned as an experimental group with a continuity of care program based on the Omaha system;61 patients admitted from December 2023 to March 2024 were designated as a control group and received routine nursing measures.The Omaha performance indicators and quality of life at 3 months after discharge were compared between 2 groups upon admission and 1 month after discharge.Results The final 2 groups each included 59 patients.A month after discharge,the Omaha efficacy index in the experimental group was higher than that in the control group,and 3 months after discharge,the quality of life in the experimental group was higher than that in the control group(P＜0.001).Conclusion The CIED patient continuity of care program based on the Omaha system could improve patients'cognitive level,promote healthy behavior,enhance their self-efficacy,and improve their quality of life.

With the rapid development of generative artificial intelligence(GAI)technologies,their widespread application in academic research and writing is continuously expanding the boundaries of sci-entific inquiry.However,this trend has also raised a series of ethical and regulatory challenges,inclu-ding issues related to authorship,content authenticity,citation accuracy,and accountability.In light of the growing involvement of AI in generating academic content,establishing an open,controllable,and trustworthy ethical governance framework has become a key task for safeguarding research integrity and maintaining trust within the academic community.This expert consensus outlines ethical requirements across key stages of AI-assisted academic writing-including topic selection,data management,citation practices,and authorship attribution.It aims to clarify the boundaries and ethical obligations surrounding AI use in academic writing,ensuring that technological tools enhance efficiency without compromising in-tegrity.The goal is to provide guidance and institutional support for building a responsible and sustainable research ecosystem.

The Animal Molecular Biology course is a crucial and foundational course for both Animal Medicine and Animal Science majors.Apart from teaching fundamental principles of molecular biology,the course provides updated applications of these principles in the field of animal science research.Im-portantly,it plays a fundamental role in cultivating students'research capabilities.With the rise of over-whelming information and their optimal utilization,the demand for integrating digital education with tradi-tional teaching methods is increasing.Based on the five years of teaching practice,this paper summarizes four highlights of the course:the construction of teaching resource,the restructuring of teaching syllabus,the adjustment of classroom teaching hours,and the improvement of assessment methodology.It focuses on Electronic-Learning"E(E-Learning)",offline classroom intensive teaching"C(Classroom)",and post-class extension to construct a blended teaching model that integrates Electronic-Learning and Class-room teaching,namely the"E+C"blended teaching model.Offline classroom teaching emphasizes the combination of theory and knowledge systems,while online Electronic-Learning mainly focuses on popular science and interesting aspects to stimulate students' interests and enthusiasm in learning.Over five years of practice,the"E+C"blended model has been proven to exert a good teaching effect.Students have reported significant gains from the course,with tightly connected and strongly complementary class-room teaching and E-Learning,which greatly aids in mastering professional knowledge.It also cultivates intrinsic motivation for learning and enhances the sense of accomplishment in acquiring knowledge,sig-nificantly improving teaching effectiveness.
