AIM: To investigate the alterations in corneal aberration and relative refractive power following the reduction of back optic zone diameters(BOZD)of orthokeratology lenses.METHODS: Myopic children aged 8-12 years, deemed suitable and willing to wear orthokeratology lenses, were randomly allocated to wear lenses with a 6.0 mm BOZD or a 5.0 mm BOZD. Data collection included changes in higher-order aberrations, relative refractive power and the treatment zone diameter of the two groups after wearing lenses for 1 d, 1 wk, 1, and 3 mo. The correlation of increase in corneal higher-order aberrations with refractive power was analyzed.RESULTS: The increases in total higher-order aberrations, spherical aberrations and coma aberrations varied over time following lens wear(all P<0.001), and there were no statistically significant differences in the changes of total higher-order aberrations and coma aberrations between the two groups of patients(all P>0.05). A significant difference was observed in the increment of spherical aberrations in the 5 mm range between the two groups of patients, which varied over time(Ftime=40.179, Ptime<0.001; Fgroup=11.948, Pgroup=0.001; Finteraction=3.262, Pinteraction=0.03). A significant difference was observed in the increment of spherical aberrations in the 4 mm range between the two patient groups(Ftime=34.462, Ptime<0.001; Fgroup=13.094, Pgroup<0.001; Finteraction=1.372, Pinteraction=0.25). There was no statistically significant distinction in relative refractive power between the two groups(Fgroup=0.048, Pgroup=0.83; Finteraction=1.208, Pinteraction=0.31); however, relative refractive power changed over time(Ftime=40.030, Ptime<0.001). The difference in treatment zone diameter between the two groups was statistically significant, with changes over time(Ftime=11.212, Ptime<0.001; Fgroup=74.073, Pgroup<0.001; Finteraction=0.312, Pinteraction=0.82). The total higher-order aberrations, spherical aberrations, and coma aberrations in 4, 5 and 6 mm range showed a positive correlation with relative refractive power values(all P<0.001). Statistically significant difference was observed in the axial length between the two groups after wearing lenses for 3, 6 and 12 mo(Ftime=185.398, Ptime<0.001; Fgroup=5.618, Pgroup=0.02; Finteraction=2.315, Pinteraction=0.11).CONCLUSION: Orthokeratology lenses leaded to elevated higher-order aberrations. Orthokeratology lenses with smaller BOZD produced significantly greater spherical aberrations at 4 and 5 mm range and smaller treatment zone diameters. The corneal total higher-order aberration was positively correlated with relative refractive power. Wearing orthokeratology lenses with a smaller BOZD can cause slower axial growth and better myopia control.

Iron overload is strongly associated with heart disease. Ferroptosis is a new form of regulated cell death indicated in cardiac ischemia-reperfusion (I/R) injury. However, the specific molecular mechanism of myocardial injury caused by iron overload in the heart is still unclear, and the involvement of ferroptosis in iron overload-induced myocardial injury is not fully understood. In this study, we observed that ferroptosis participated in developing of iron overload and I/R-induced cardiomyopathy. Mechanistically, we discovered that Parkin inhibited iron overload-induced ferroptosis in cardiomyocytes by promoting the ubiquitination of long-chain acyl-CoA synthetase 4 (ACSL4), a crucial protein involved in ferroptosis-related lipid metabolism pathways. Additionally, we identified p53 as a transcription factor that transcriptionally suppressed Parkin expression in iron-overloaded cardiomyocytes, thereby regulating iron overload-induced ferroptosis. In animal studies, cardiac-specific Parkin knockout mice (Myh6-CreER T2 /Parkin fl/fl ) fed a high-iron diet presented more severe myocardial damage, and the high iron levels exacerbated myocardial I/R injury. However, the ferroptosis inhibitor Fer-1 significantly suppressed iron overload-induced ferroptosis and myocardial I/R injury. Moreover, Parkin effectively protected against impaired mitochondrial function and prevented iron overload-induced mitochondrial lipid peroxidation. These findings unveil a novel regulatory pathway involving p53-Parkin-ACSL4 in heart disease by inhibiting of ferroptosis.

Objective To investigate the potential mechanism by which dihydromyricetin(DHM)ameliorates diabetic nephropathy(DN),and to screen and validate its possible key molecular targets.Methods A DN model was established using db/db mice,and 100 mg/(kg·d)DHM was administered via gavage 5 d per week for totally 10 weeks.Renal morphological changes were observed after staining to evaluate the effects of DHM.GSE161885 and GSE270526 datasets were obtained from the Gene Expression Omnibus(GEO)database and analyzed in combination with the GeneCards database to screen for DN-related differentially expressed genes(DEGs).Protein-protein interaction(PPI)network and molecular docking were employed to predict potential DHM targets.Western blotting and immunofluorescence staining were performed to detect the effects of DHM on pyroptosis-related pathways in the renal tissues of db/db mice and in high glucose(HG)-induced human renal tubular epithelial cells(HK-2).The specific NLR family pyrin domain containing protein 3(NLRP3)inhibitor MCC950 was also used to validate the predicted mechanism.Results In vivo experiments showed that DHM significantly ameliorated renal pathological damage in db/db mice,alleviated glomerular hypertrophy and mesangial expansion,and markedly reduced Paller scores(P<0.001).Immunofluorescence staining revealed significantly weakened fluorescence signals for α-smooth muscle actin(α-SMA),fibronectin,and collagen Ⅰ in renal tissues.Western blot results showed that the expression levels of collagen Ⅰ,collagen Ⅲ,α-SMA,and transforming growth factor beta 1(TGF-β1)were significantly decreased(P<0.05).A total of 16 DN-related DEGs were identified.Enrichment analysis revealed that these genes were primarily enriched in pathways such as viral protein interactions,cytokine-cytokine receptor interaction,and the AGE-RAGE signaling pathway in diabetic complications,and were primarily involved in gene functions such as the positive regulation of lymphocyte-mediated immunity,positive regulation of adaptive immune response,and chemokine activity.Molecular docking confirmed NLRP3 as a potential target of DHM.In vivo validation showed that DHM significantly down-regulated gasdermin-D(GSDMD)fluorescence signals and inhibited the expression of pyroptosis-related proteins including NLRP3,Caspase 1,Cleaved-Caspase 1,interleukin 18(IL-18),and GSDMD(P<0.05).In vitro studies further confirmed that both DHM and the specific NLRP3 inhibitor MCC950 alleviate high glucose-induced fibrosis and pyroptosis in HIC-2 cells.Conclusion DHM can ameliorate the progression of DN,and its mechanism is related to inhibiting NLRP3 inflammasome-mediated pyroptosis,thereby alleviating renal inflammation and fibrosis.
