Heart failure is known as a complex clinical syndrome. Many studies have shown that insulin resistance is closely related to heart failure and is considered to be an important factor in heart failure. The triglyceride-glucose index(TyG) has been shown to be significantly associated with insulin resistance. An increasing number of studies have confirmed the relationship between TyG and various cardiovascular diseases. Heart failure is the end stage of multiple cardiovascular diseases. This article summarizes the correlation between TyG and the occurrence, development, and prognosis of heart failure, and discusses the shortcomings of the triglyceride glucose index in research, providing new ideas and strategies for the treatment of heart failure.

Objective Aiming to develop a distance-adaptive visual function self-examination system based on tablet computers and evaluate its accuracy.Methods Utilizing ArUco technology on a tablet device equipped with the camera,a system was developed to assess visual functions by identifying QR codes within a 2-meters range for real-time ranging.This system integrates various visual function tests,including visual acuity test(conventional visual acuity test and high-pass visual acuity test with varying contrasts),accommodative amplitude test,and visual field test at the foveal(5°).A total of 22 healthy subjects(44 eyes)participated in visual function assessments,with 6 subjects undergoing visual acuity tests at varying distances(1 m,1.25 m,1.6 m,2 m)and accommodative amplitude tests under both refractive correction and simulated undercorrection of-3.00D.The program distance and actual distance were compared,the consistency of visual acuity outcomes for identical optotype at different distances were assessed,the accommodative amplitude under refractive correction and undercorrection were analyzed,the repeatability of accommodative amplitude outcomes was evaluated using Intraclass Correlation Coefficient(ICC),and the contrast threshold and efficacy of visual field test outcomes were analyzed.Results The program distance and actual distance showed good agreement.High-pass visual acuity tests with the same contrast showed no significant differences at different distances(P?>?0.05),while conventional visual acuity tests showed significant differences at distances of 0.9 to 1.1 meters compared to other distances(P?

Bow hunter′s syndrome, also known as vertebral basilar artery insufficiency, is a rare disease characterized by post-circulation blood supply insufficiency caused by mechanical or stenosis of the vertebral artery when the head and neck rotate or over-extend. To date, few cases regarding the bilateral hunter′s bow syndrome concurrent with epilepsy have been reported. A 29-year-old man was admitted to the First Hospital of Jilin University due to seizures. Results from transcranial Doppler ultrasound and carotid ultrasound showed that the patient had bilateral hunter′s bow syndrome. Further imaging examination showed that the syndrome was caused by congenital bone fusion which resulted in mechanical occlusion of C₁-C₂ vertebral artery. This case indicates that seizures are closely related to hunter′s bow syndrome.
