Dry eye disease is a chronic ocular surface disorder of multifactorial origin, characterized by a loss of tear film homeostasis and associated with a range of ocular discomfort symptoms. Growing evidence underscores a significant bidirectional relationship between dry eye and depression: individuals with dry eye disease exhibit a higher prevalence of depressive disorders, and conversely, those diagnosed with depression demonstrate an increased susceptibility to developing dry eye. This interplay is mediated through several pathophysiological pathways, such as chronic inflammation, cerebral functional alterations, gut microbiome dysregulation, and sleep disturbances, which may collectively sustain a vicious cycle. The use of antidepressant therapy introduces further complexity, exerting heterogeneous effects on dry eye—some agents may offer symptomatic relief, whereas others can aggravate ocular surface impairment. The mechanisms responsible for these differential outcomes remain incompletely elucidated and merit further investigation. This review systematically consolidates epidemiological data on the dry eye-depression link, examines potential shared pathological mechanisms, and evaluates current therapeutic options. We propose an integrated management approach that combines conventional dry eye treatments, such as traditional Chinese medicine, electroacupuncture, physical activity and antidepressants—a multimodal strategy that may yield synergistic benefits in alleviating both ocular and affective symptoms, thereby improving overall quality of life. Moving forward, research should focus on deciphering the underlying mechanistic pathways and facilitating the translation of these insights into clinical practice to inform targeted, combined treatment regimens for patients with dry eye and depression.

Ketone body metabolism plays a significant role in the development and progression of diabetic retinopathy(DR), which closely related to the system and local metabolic disorders as a major microvascular complication of diabetes mellitus. Previous research has established a close relationship between dyslipidemia and DR progression. Ketone bodies, comprising β-hydroxybutyrate, acetoacetate, and acetone, are metabolic products generated from fat breakdown when glucose metabolism is impaired. Studies have revealed that ketone body metabolism is intricately linked to multiple pathophysiological processes in DR, including oxidative stress, inflammatory responses, and neurodegeneration within retinal cells. This article provides a review exploring the impact of ketone body metabolism on the pathogenesis of DR, and systematically reviews the latest research progress on the impact of ketone bodies on the core pathological links such as retinal vascular barrier destruction, glial cell activation and angiogenesis through metabolic reprogramming, epigenetic modification and cell signal transduction, so as to provide a theoretical basis for in-depth understanding of the metabolic driving mechanism of DR.

OBJECTIVE To explore the efficacy and influencing factors of intravitreal injection of ranibizumab in the treatment of macular edema （ME） secondary to retinal vein obstruction （RVO） with different optical coherence tomography （OCT） subtypes. METHODS A retrospective study was conducted on 150 patients with ME secondary to RVO treated at Dept. of Ocular Trauma of Tianjin Eye Hospital between January 1， 2021 and January 1， 2024. According to OCT findings， patients were classified into the diffuse retinal thickening （DRT） group （48 cases）， cystoid macular edema （CME） group （83 cases）， and serous retinal detachment （SRD） group （19 cases）. The best corrected visual acuity （BCVA） and central macular thickness （CMT） were compared before and at 1， 3 and 6 months after treatment. Clinical efficacies of 3 groups were compared based on CMT and fluorescein fundus angiography （FFA） findings before and after treatment. Adverse events and the number of additional injections of ranibizumab during treatment were compared among 3 groups. Using “ineffectiveness” in clinical outcomes at 6 months post- treatment as the dependent variable and patients’ baseline data as the independent variables， a multivariate Logistic regression analysis was conducted to identify risk factors influencing the clinical efficacy of ranibizumab. RESULTS The proportion of branch RVO was significantly higher in the CME and SRD groups than in the DRT group （P＜0.05）， while central RVO （CRVO） was more frequent in the DRT group than in the CME and SRD groups （P＜0.05）. The proportion of patients with ischemia was highest in the SRD group， followed by the CME and DRT groups （P＜0.05）， while the proportion of patients with ischemia in the CME group was significantly higher than that in the DRT group （P＜0.05）. Before treatment， the BCVA and CMT showed no significant differences among the 3 groups （P＞0.05）. After treatment， BCVA and CMT in all 3 groups were significantly reduced compared to those before treatment （P＜0.05）. At different treatment time points， patients in the CME group and SRD group consistently showed significantly higher BCVA and CMT values compared to those in the DRT group （P＜0.05）. Six months after treatment， the differences in clinical efficacy among the 3 groups were statistically significant （P＜0.05）， with the proportion of non-responders in the SRD group being significantly higher than that in the DRT group and the CME group （P＜0.05）. The number of additional injections of ranibizumab in patients from the CME group and the SRD group was significantly more than that in the DRT group （P＜0.05）. The incidence of adverse reactions did not differ significantly among 3 groups （P＞0.05）. Multivariate Logistic regression revealed that CRVO and ischemic type were common risk factors affecting the clinical efficacy of ranibizumab in all 3 groups， while longer disease duration was an independent risk factor for the clinical efficacy of ranibizumab in patients from the DRT group. CONCLUSIONS The therapeutic efficacy of ranibizumab varies among different OCT phenotypes of ME secondary to RVO. DRT patients achieve the best visual improvement， SRD patients have the highest non-response rate， and CME/SRD patients require more additional injections of ranibizumab. CRVO and ischemia are shared adverse prognostic factors for poor prognosis in various subtypes of ME secondary to RVO. Individualized treatment and follow-up strategies should be developed based on OCT patterns and risk factors.

OBJECTIVE: To study the effects and mechanisms of juglone on the proliferation and apoptosis of acute myeloid leukemia (AML) cells. METHODS: Juglone and AML targets were collected from public databases, and the intersecting target clusters were taken for functional enrichment analysis to explore the potential mechanism of juglone in the treatment of AML. Then wet experiments were performed to verify. AML cell lines including KG-1a, MV-411, THP-1 and MOLM-13 were treated with different concentrations of juglone for 24 h. MTT assay was used to detect cell viability and determine the IC₅₀, and the most sensitive cell line was screened for subsequent experiments. Flow cytometry was used to detect the apoptosis of cells treated with different concentrations of juglone. Western blot was performed to check the expression of relevant proteins. RESULTS: Eleven targets were obtained as potential targets for juglone in the treatment of AML, and the top ten significantly enriched pathways were intrinsic pathway of apoptosis, programmed cell death, cytochrome c-mediated apoptotic response, apoptosis, apoptotic factor-mediated response, regulated necrosis, cytokine signaling in immune system, signaling by interleukins, oncogene induced senescence, and signal transduction. The cell viability of KG-1a, MV-411, THP-1 and MOLM-13 was decreased with increasing juglone concentration after 24 h of juglone treatment (r =-0.992, -0.886, -0.956, -0.910). Among them, MOLM-13 was the most sensitive to juglone. The results of flow cytometry showed that the apoptosis rate of MOLM-13 tended to significantly increase with the increasing concentration of juglone (r =0.99). At the same time point, p-RIPK1/RIPK1, p-RIPK3/RIPK3, and p-MLKL/MLK were decreased in each juglone concentration group compared with control group. CONCLUSION Juglone inhibits the viability of KG-1a, MV-411, THP-1 and MOLM-13 cells, and induces apoptosis of MOLM-13 cells, the mechanism of which may be related to the inhibition of RIPK1/RIPK3/MLKL signaling pathway.

The visual cortex is an essential part of the brain for processing visual information. It exhibits structural and functional plasticity, which is crucial for adapting to complex visual environments. The quintessential manifestation of visual cortical plasticity is ocular dominance plasticity during the critical period, which involves numerous cellular and molecular events. While previous studies have emphasized the role of visual cortical neurons and their associated functional molecules in visual plasticity, recent findings have revealed that structural factors such as the extracellular matrix and glia are also involved. Investigating how these molecules interact to form a complex network that facilitates plasticity in the visual cortex is crucial to our understanding of the development of the visual system and the advancement of therapeutic strategies for visual disorders like amblyopia.

The foveal avascular zone(FAZ)is the most sensitive region of the retina, which is interconnected by the macular capillary plexus. Its morphology can indirectly reflect the alterations of macular microcirculation. With strong repeatability and reliability, optical coherence tomography angiography(OCTA)can non-invasively visualize and quantify the FAZ. The great value of OCTA makes it an important supplemental examination tool in ophthalmology and other professions. The area and perimeter of FAZ have been demonstrated to be an effective clinical diagnostic indicator in high myopia, diabetic retinopathy, glaucoma and other ocular diseases. In recent years, the geometry of FAZ has also proven to have clinical value. The parameters describing the geometry of FAZ, such as circularity index, acircularity index and axial ratio, provide a new perspective for ocular disease research. The comprehensive investigation of the morphological characteristics of the FAZ is helpful to explore the pathological mechanism of the occurrence and development of ocular diseases, predict preclinical changes, make pathological stages of the disease precise, and provide a theoretical basis for monitoring the disease's progression and assessing patients' visual prognosis.
