International Eye Science 2026;26(3):523-527
AIM:To investigate the predictive value of central corneal thickness(CCT)and coefficient of variation(CV)of endothelial cell area for secondary glaucoma in patients with uveitis.METHODS: A retrospective study was conducted on uveitis patients admitted to our hospital from July 2023 to April 2025. Based on the occurrence of secondary glaucoma, patients were divided into an occurrence group and a non-occurrence group, and the clinical data of the two groups were compared. Univariate and multivariate Logistic regression analyses were performed to screen for factors affecting poor prognosis. The predictive value of CCT and CV for secondary glaucoma in patients with uveitis was analyzed using receiver operating characteristic(ROC)curves.RESULTS: A total of 100 uveitis patients(100 eyes)were included and categorized into an occurrence group(16 cases, 16 eyes)and a non-occurrence group(84 cases, 84 eyes), there were 9 males and 7 females in the occurrence group, with a mean age of 45.25±10.32 years, and there were 40 males and 44 females in the non-occurence group, with a mean age of 43.89±12.47 years. The CCT in the occurrence group was significantly lower than that in the non-occurrence group, while the CV was significantly higher than that in the non-occurrence group(both P<0.001). Multivariate Logistic regression analysis showed that CCT was a protective factor, and CV was a risk factor for secondary glaucoma in patients with uveitis(both P<0.01). The areas under the ROC curve(AUC)for CCT and CV in predicting secondary glaucoma were 0.794 and 0.792, respectively. The combined predictive model yielded an AUC of 0.888, with a sensitivity of 98.15% and a specificity of 67.74%, demonstrating good predictive efficacy.CONCLUSION: CCT and CV have certain clinical value in predicting secondary glaucoma in uveitis patients. The combined diagnostic approach demonstrates higher efficacy and serves as an auxiliary indicator for assessing the risk of secondary glaucoma in patients with uveitis, allowing for targeted clinical prevention and treatment measures.

ObjectiveTo investigate the mechanism of Guizhi Fulingwan (GFW) against hepatic fibrosis, focusing on elucidating the regulatory effect of GFW on the mitochondrial DNA (mtDNA)/NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate-specific proteinase-1 (Caspase-1)/gasdermin D (GSDMD) signaling pathway. MethodsForty-two male Sprague-Dawley (SD) rats were randomly allocated into six groups (n=7): control, model, low/medium/high-dose (0.14, 0.28, 0.56 g·kg-1·d-1) GFW (GFW-L, GFW-M, GFW-H), and Dahuang Zhechong pills (DZW, 1.8 g·kg-1·d-1). The rat model of hepatic fibrosis was induced by intraperitoneal injection of carbon tetrachloride. General conditions of the rats were observed. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured. Liver histopathology and collagen deposition were observed through hematoxylin and eosin (HE) staining and Masson's trichrome staining. Transmission electron microscopy (TEM) was employed to observe structural alterations and damage of cellular ultrastructures including mitochondria. Mitochondrial membrane potential (MMP, ΔΨm) was detected by flow cytometry. Serum levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) were measured by enzyme-linked immunosorbent assay (ELISA). The mRNA levels of mtDNA and NLRP3 in the liver tissue were quantified by Real-time polymerase chain reaction (Real-time PCR). The protein levels of key molecules in the NLRP3/Caspase-1/GSDMD signaling pathway in the liver tissue were determined by Western blot. ResultsCompared with the control group, the model group exhibited a decrease in body weight (P<0.01), an increase in liver index (P<0.01), elevations in serum ALT and AST levels (P<0.01), and typical fibrotic features such as disorganized hepatocytes, inflammatory infiltration, and increased collagen deposition in the liver tissue. TEM revealed significant karyotheca degeneration, mitochondrial swelling, endoplasmic reticulum expansion, and organelle efflux in the model group. In addition, the model group showed decreased ΔΨm (P<0.01), up-regulated mRNA levels of mtDNA and NLRP3 (P<0.01) and protein levels of NLRP3, Caspase-1, and GSDMD (P<0.01) in the liver tissue, and increased serum levels of IL-1β and IL-18 (P<0.01). Compared with that in the model group, the body weight increased in GFW-L, GFW-M, and DZW groups (P<0.05) and markedly increased in the GFW-H group (P<0.01). The liver index decreased in the GFW groups and DZW group (P<0.01). The serum ALT level declined in the GFW-L group (P<0.05), and the serum ALT and AST levels decreased in the GFW-M, GFW-H, and DZW groups (P<0.01). Histopathological damage and fibrosis were alleviated to varying degrees, and TEM revealed mitigated ultrastructural injuries including mitophagy, mitochondrial swelling, and endoplasmic reticulum expansion in the drug intervention groups. The ΔΨm increased in GFW groups without statistical significance. The mRNA level of mtDNA in the liver tissue was down-regulated in the GFW-M (P<0.05), GFW-H (P<0.01), and DZW (P<0.01) groups. The mRNA level of NLRP3 was down-regulated in GFW-M, GFW-H, and DZW groups (P<0.01). Western blot analysis showed significantly down-regulated protein level of NLRP3 in all the GFW groups and the DZW group (P<0.01). The protein level of GSDMD-N was down-regulated in GFW-H and DZW groups (P<0.01). The protein level of cleaved Caspase-1 was down-regulated in GFW-M (P<0.05), GFW-H (P<0.01), and DZW (P<0.01) groups. In addition, the serum levels of IL-1β and IL-18 declined in GFW-H and DZW groups (P<0.01). ConclusionGFW can suppress pyroptosis to ameliorate CCl4-induced hepatic fibrosis, potentially through mitigating mitochondrial damage, inhibiting inflammasome assembly and activation, and blocking pro-inflammatory cytokine release.

High-altitude retinopathy(HAR)is a retinal vascular disorder induced by exposure to high-altitude environments. With the increasing popularity of high-altitude travel, mountaineering, and special occupational activities, worldwide, the incidence of HAR has risen, particularly among individuals with rapid or short-term exposure to elevated altitudes. Most cases of HAR are self-limiting and gradually resolve with descent to lower altitudes. However, severe cases may result in permanent visual function impairment if not recognized and managed promptly. This review systematically summarizes the epidemiology, diagnostic progress, pathogenesis, and prevention and treatment strategies of HAR, with particular emphasis on hypoxia-associated molecular pathways involved in retinal damage, and evaluates current evidence for clinical interventions. Deepened understanding of its pathological mechanisms and clinical management strategies facilitates early identification, targeted intervention, and ocular health protection for populations exposed to high altitudes.

Chronic heart failure (CHF) is the final stage of cardiovascular diseases. It is a complex syndrome, with dyspnea and edema as the main clinical manifestations, and it is characterized by complex disease conditions, difficult cure, and high mortality. Ferroptosis, a new type of programmed cell death, is different from other types of programmed cell death. Ferroptosis is iron-dependent, accompanied by lipid peroxide accumulation and mitochondrial shrinkage, becoming a hot research topic. Studies have confirmed that ferroptosis plays a key role in the occurrence and development of CHF. The regulation of ferroptosis may become a potential target for the treatment of CHF in the future. The theory of Qi deficiency and stagnation refers to the pathological state of original Qi deficiency and abnormal transportation and distribution of Qi, blood, and body fluid, which has guiding significance for revealing the pathogenesis evolution of some chronic diseases. We believe that Qi deficiency and stagnation is a summary of the pathogenesis of ferroptosis in CHF. Deficiency of Qi (heart Qi) is the root cause of CHF, and stagnation (phlegm turbidity and blood stasis) is the branch of this disease. The two influence each other in a vicious circle to promote the development of this disease. Traditional Chinese medicine (TCM) plays an important role in the treatment of CHF, improving the prognosis and quality of life of CHF patients. This paper explores the correlation between the theory of Qi deficiency and stagnation and the mechanism of ferroptosis in CHF. Furthermore, this paper reviews the mechanism of Chinese medicines and compound prescriptions in preventing and treating CHF by regulating ferroptosis according to the principles of replenishing Qi and dredging to remove stagnation, aiming to provide new ideas and methods for the treatment of CHF with TCM.

The high comorbidity and heterogeneity of obsessive-compulsive disorder (OCD) underscore the importance of better understanding its transdiagnostic features. Intolerance of uncertainty (IU), a transdiagnostic negative psychological trait, has been consistently linked to a variety of psychiatric disorders, including OCD. IU is hierarchically structured, comprising general IU, inhibitory IU and prospective IU, each of them potentially relating differently to OCD symptom dimensions. For example, inhibitory IU has shown specific associations with procrastination behaviors. Neuroimaging studies indicate that OCD patients demonstrate abnormal neural activity within the fronto-limbic circuit and salience network, including anterior insula, amygdala and ventromedial prefrontal cortex, during IU-related psychological processes. This review synthesizes findings across three key areas: symptom presentation, neurobiological mechanisms and intervention strategies, aiming to clarify the role of IU in OCD. Furthermore, the potential of targeting IU therapeutically to complement first-line treatment is discussed, ultimately enhancing clinical intervention outcomes.
