Correlation Study of Aortic Velocity Propagation, Abdominal Aortic Intima-Media Thickness, and Epicardial Adipose Tissue Thickness in Subclinical Hypothyroidism Patients

Objective:To explore the correlation between epicardial fat thickness(EFT),aortic velocity propagation(AVP),and abdominal aortic intima-media thickness(AA-IMT)in patients with subclinical hypothyroidism(SH).Additionally,to compare these indicators between SH patients and healthy individuals,providing a new theoretical basis for the clinical prevention and treatment of cardiovascular diseases.Method:Clinical data from 50 SH patients(23 males and 27 females)and 50 healthy outpatient examinees(22 males and 28 females)were analyzed.The participants were selected from January 2022 to December 2023 at Loudi Central Hospital.EFT,AVP,and AA-IMT were measured,and their correlations were analyzed.Results:SH patients had significantly higher EFT and AA-IMT levels than the control group,while their AVP was significantly lower,with these differences being statistically significant(P<0.05).Correlation analysis revealed a significant negative correlation between EFT and AVP(P<0.001),a significant positive correlation between EFT and AAO-IMT(P<0.001),and a significant negative correlation between AVP and AAO-IMT(P<0.001).Multivariate binary logistic regression analysis identified increased EFT,decreased AVP,and increased AAO-IMT as independent risk factors for SH patients.Conclusion:In SH patients,EFT and AAO-IMT are elevated,whereas AVP is reduced.EFT and AVP are significantly correlated with AAO-IMT.EFT and AAO-IMT can serve as reliable indicators for evaluating subclinical atherosclerosis in SH patients,providing a diagnostic basis for clinical practice.

Challenges and Teaching Reform Strategies in Vocational College Engineering Training Courses

With the rapid development of vocational education,engineering training has become a crucial course for cultivating highly skilled technical professionals,highlighting its importance.However,vocational college engineering training courses still face numerous challenges during the actual teaching process,which affect the effectiveness of course teaching and the enhancement of students’engineering competence.This article thoroughly analyzes the main problems existing in current engineering training course teaching,focusing on four aspects:students’cognitive differences,inadequate course development,poor course adaptability,and limited teaching resources.Based on this analysis and previous research findings,targeted strategies are proposed,including enhancing students’course cognition,clarifying course positioning,improving course adaptability,and optimizing the allocation of teaching resources.Furthermore,this article preliminarily verifies the effectiveness of some reform strategies through a small-scale teaching experiment.This study aims to provide theoretical guidance and practical reference for enhancing the teaching quality of vocational college engineering training courses.
