Myocardial ischemia–reperfusion injury (MIRI) was often observed after surgeries, causing a lot of suffering to patients. Inflammation and apoptosis were critical determinants during MIRI. We conveyed experiments to reveal the regulatory functions of circHECTD1 in MIRI development. The Rat MIRI model was established and determined by 2,3,5‐triphenyl tetrazolium chloride (TTC) staining. We analyzed cell apoptosis using TUNEL and flow cytometry. Proteins expression was evaluated by western blot. The RNA level was determined by qRT‐PCR. Secreted inflammatory factors were analyzed by ELISA assay. To predict the interaction sequences on circHECTD1, miR‐138‐5p, and ROCK2, bioinformatics analysis was performed. Dual‐luciferase assay was used to confirm these interaction sequences. CircHECTD1 and ROCK2 were upregulated in the rat MIRI model, while miR‐138‐5p was decreased. CircHECTD1 knockdown alleviated H/R‐induced inflammation in H9c2 cells. Direct interaction and regulation of circHECTD1/miR‐138‐5p and miR‐138‐5p/ROCK2 were confirmed by dual‐luciferase assay. CircHECTD1 promoted H/R‐induced inflammation and cell apoptosis by inhibiting miR‐138‐5p. miR‐138‐5p alleviated H/R‐induced inflammation, while ectopic ROCK2 antagonized such effect of miR‐138‐5p. Our research suggested that the circHECTD1‐modulated miR‐138‐5p suppressing is responsible for ROCK2 activation during H/R‐induced inflammatory response, providing a novel insight into MIRI‐associated inflammation.

Aims The study aims to evaluate the quality of life ( QOL) and health of children with unclassified developmental delays and the impacts this had on the family. Methods In total, 60 parents of pre-school children with unclassified developmental delays and 56 parents of age and gender-matched children with typical development were recruited. We administered the Pediatric Quality of Life Inventory ( PedsQL)- Generic Core Scale and Pediatric Outcomes Data Collection Instrument to parents to evaluate the QOL and health status of their children. Parents were evaluated by World Health Organization- Quality of Life- Brief Version, PedsQL- Family Impact Module, Hospital Anxiety and Depression Scale, and PedsQL- Health satisfaction to assess the impacts of this situation on the family. Variables related to QOL and functions of children with unclassified developmental delays were analysed by stepwise regression analysis. Results Comparing children with typical development, children with unclassified developmental delays had a significantly lower QOL (including both psychosocial and physical components) and health status. Their parents had a significantly lower QOL, family function and health satisfaction, and higher psychological distress than parents of children with typical development. Gross-motor delay impacts on QOL of these children (regression coefficient: −9.59, P < 0.05), global functioning is related to cognition delay (regression coefficient: −20.22, P < 0.01) and physical health of their parents (regression coefficient: 0.87, P < 0.01). Conclusions Children with unclassified developmental delays had lower QOL and health status, and their condition had greater impacts on the family than children with typical development. Gross motor and cognition development related to the QOL and global functioning in these children. [ABSTRACT FROM AUTHOR]
