Objective: To study the efficacy of bedside treatment by laser photocoagulation for retinopathy of prematurity (ROP) in preterm infants hospitalized in the Neonatal Intensive Care Unit (NICU).
Methods: The clinical data of 30 cases of ROP who underwent peripheral laser ablation on bedside in the NICU from March to August 2009 were studied retrospectively.
Results: A total of 59 eyes from 30 patients received the laser therapy, with a total cure rate of 95%. According to the International Classification of ROP, 26 eyes of 13 infants had zone 1 disease, and 33 eyes of 17 infants had zone 2 disease. The birth gestational age and birth weight as well as corrected gestational age and corrected weight at operation in the zone 1 disease group were significantly lower than those in the zone 2 disease group. The number of laser spots in the zone 1 disease group was significantly higher than that in the zone 2 disease group. The cure rate in the zone 2 disease group (100%) was significantly higher than that in the zone 1 disease group (88%).
Conclusions: Laser retinal photocoagulation on bedside in the NICU is effective for both zone 1 and zone 2 ROP. As compared with the infants with zone 2 disease, the infants with zone 1 disease may have a poor outcome.

Abdominal aortic aneurysm (AAA) is the most prevalent dilated arterial aneurysm that poses a significant threat to older adults, but the molecular mechanisms linking senescence to AAA progression remain poorly understood. This study aims to identify cellular senescence-related genes (SRGs) implicated in AAA development and assess their potential as therapeutic targets. Four hundred and twenty-nine differentially expressed genes (DEGs) were identified from the GSE57691 training set, and 867 SRGs were obtained.

Background: Seasonality in the incidence of congenital hypothyroidism (CH) has been identified in several countries and different conclusions have been drawn. The objective of this study was to examine whether this seasonality is also observable in China and how it manifests across different temperate zones.
Methods: Data on CH cases and screened neonates between January 1, 2014, and September 30, 2022, by year and season, were sourced from the Chinese Newborn Screening Information System.

Diabetic cardiomyopathy (DCM) is a medical condition characterized by cardiac remodeling and dysfunction in individuals with diabetes mellitus. Sarcoplasmic reticulum (SR) and mitochondrial Ca overload in cardiomyocytes have been recognized as biological hallmarks in DCM; however, the specific factors underlying these abnormalities remain largely unknown. In this study, we aimed to investigate the role of a cardiac-specific long noncoding RNA, D830005E20Rik (Trdn-as), in DCM.

Purpose: To determine how Hardy-Rand-Rittler (HRR) colour vision testing correlates with visual functional and structural assessments in Cone and Cone-Rod Dystrophy.
Methods: Thirty-four Cone and 69 Cone-Rod Dystrophy patients diagnosed by electroretinography (ERG) at the Save Sight Institute in Sydney were included in a retrospective analysis. Each patient's HRR colour vision test scores were compared with markers of cone and rod system function including visual acuity (VA), ERG responses, changes on Spectral Domain Optical Coherence Tomography (OCT) and Fundus Autofluorescence.
