Retinal vein occlusion(RVO)is the second most common blinding retinal vascular disease, and its secondary macular edema(ME)is an important cause of visual function impairment in patients. Intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs serves as the first-line treatment, yet it is confronted with such issues as the need for repeated injections and non-response in some patients. Imaging and laboratory biomarkers play a crucial role in the early accurate diagnosis, prediction of disease progression, and evaluation of visual prognosis of RVO-ME. This study systematically reviews the research progress of imaging and laboratory biomarkers related to the prognosis of RVO-ME after anti-VEGF treatment in recent years, covering imaging biomarkers like central retinal thickness and ellipsoid zone integrity, as well as laboratory biomarkers such as serum APLN and aqueous humor IL-6. It summarizes the associations between different biomarkers and the prognosis of anti-VEGF therapy, aiming to provide a basis for the early accurate assessment and optimization of individualized treatment for RVO-ME patients, which holds significant clinical reference value.

Dry eye is a chronic ocular surface disease caused by multiple factors. It is caused by the instability of tear film and the imbalance of the microenvironment of ocular surface, and may be accompanied by ocular surface inflammation, damage, and abnormal nerve sensation. The instability of tear film is its core characteristic. Mucin is an important component of the tear film and plays a role in stabilizing the tear film. The reduction of its secretion and the change of its structure lead to the occurrence and development of dry eye. The intracellular Ca2+ signal is the key to controlling the secretion of water and enzymes by exocrine glands. A decrease in the Ca2+ signal can cause dry eye. Conjunctival goblet cells are the main cells that secrete mucin. By activating the intracellular PLC-IP3-Ca2+ pathway, RyRs pathway, cAMP signaling pathway, P2X receptor, BLT1 and ChemR23 receptors, cholinergic receptor, and ALX signaling pathway, the content of Ca2+ can be increased, and the replenishment of mucin granules can be accelerated, thereby relieving the symptoms of dry eye. The Ca2+ signaling pathway may be an important target for the treatment of dry eye. This article reviews the role of mucin in dry eye and the influence of the Ca2+ signal on the secretion of mucin by conjunctival goblet cells.

Objective To investigate the expression characteristics of granzyme B(GZMB)and C-X-C motif chemokine ligand 9(CXCL9)in gastric cancer(GC)tissues,explore their association with the tumor immune microenvironment(TME),and evaluate their clinical prognostic significance.Methods Bioinformatic analyses were conducted using public databases(TIMER,GEPIA,UALCAN)to validate the expression levels of GZMB and CXCL9 across various cancer types,with a focus on GC.Paired tumor and adjacent normal tissue samples were collected from 89 GC patients who underwent radical gastrectomy at Nanyang First People's Hospital between 2018 and 2019.The mRNA expression levels of GZMB and CXCL9 were measured using quantitative real-time PCR(qRT-PCR),and their associations with clinicopathological characteristics were statistically analyzed.Immune cell infiltration levels were estimated using the TIMER and GSCA databases.Diagnostic performance was evaluated through receiver operating characteristic(ROC)curve analysis,while survival outcomes were assessed using data from the Kaplan-Meier Plotter database and patient follow-up records.Results Both database analysis and qRT-PCR results demonstrated that GZMB and CXCL9 expression levels were significantly elevated in GC tissues compared to adjacent non-tumor tissues(P<0.05).Clinical correlation analysis revealed no significant associations between mRNA expression levels of GZMB and CXCL9 and clinicopathological parameters,including gender,age,pathological type,tumor differentiation,TNM stage,tumor size,or lymph node metastasis(P>0.05).Immune infiltration analysis indicated that both genes were significantly positively correlated with CD8+T cell and dendritic cell infiltration(P<0.05),while showing a negative correlation with B cell infiltration(P<0.05).ROC curve analysis showed that the combined detection of GZMB and CXCL9 yielded an AUC of 0.890(95%CI:0.843～0.936),which was higher than that of GZMB alone(AUC=0.832,95%CI:0.772～0.891)or CXCL9 alone(AUC=0.782,95%CI:0.715～0.850).Survival analysis further revealed that patients with high expression of GZMB and CXCL9 had significantly improved overall survival compared to those with low expression(P<0.05).Conclusion GZMB and CXCL9 are highly expressed in GC and are strongly associated with the infiltration of anti-tumor immune cells.These molecules represent promising diagnostic biomarkers for GC,and their elevated expression is correlated with a more favorable prognosis in patients.

Ocular trauma is a leading cause of permanent visual impairment and loss of working a-bility.Among them,orbital foreign body injuries are often accompanied by multiple injuries to the eye-ball and surrounding tissues,adversely affecting the quality of life.This paper reported a 33-year-old male patient with right orbital foreign body resulting in eyeball contusion,extraocular muscle injury,and restricted ocular movement.After surgical removal of the foreign body combined with integrated traditional Chinese and western medicine treatment,the patient's visual acuity improved from 0.4 to 0.8,and ocular motility function significantly improved.This suggests that comprehensive treatment contributes to promoting functional recovery and enhancing clinical efficacy.

Objective To analyze the epidemiological burden of age-related macular degeneration(AMD)in China and low-,middle-,and high-socio-demographic index(SDI)countries,thereby providing a theoretical foundation for the prevention and control of AMD.Methods The data published by Global Burden of Disease(GBD)from 1990 to 2021,in-cluding the number of cases,prevalence,disability-adjusted life years(DALYs),and DALYs rate,were utilized to analyze the characteristics of AMD in China and low-,middle-,and high-SDI countries and assess the burden of AMD and its corre-lation with SDI.Results In 2021,the number of patients with AMD and DALYs in China ranked first in the world.Be-sides,the age-standardized prevalence rate(ASPR)and age-standardized DALYs rate(ASDR)in China ranked 46th and 64th in the world,respectively.The number of patients with AMD and DALYs in high-SDI countries were significantly lower than those in middle-and low-SDI countries.The ASPR and ASDR in China were higher than those in high-SDI countries but lower than those in low-SDI countries,and both exceeded the global averages.The prevalence of AMD among people aged 55 years and above was significantly higher.In high-SDI countries,the highest prevalence of AMD was observed a-mong people aged 80 years or above.The prevalence of AMD in China and middle-SDI countries peaked among people aged 65-69 years;whereas that in low-SDI countries peaked among people aged 75-79 years.The AMD burden in females was significantly higher than that in males.The global number of AMD patients exhibited an increasing trend from 1990 to 2021,with the fastest increase observed in China(3.11-fold).The ASPR in China showed a wave-like increasing trend,while that in low-,middle-,and high-SDI countries showed a decreasing trend during the same period.The overall DALY showed an increasing trend,and the increase in the DALYs in China(2.84-fold)exceeded that in low-,middle-,and high-SDI countries.However,the overall ASDR declined,with the most significant decline observed in high-SDI countries.The AS-DR in China has recently rebounded after a wave-like decline from 1990 to 2021.The analysis results of the slope index of inequality(SII)and concentration index(CI)showed that the gap in the AMD burden between high-income and low-in-come countries widened progressively from 1990 to 2021,with the burden being more severe in low-SDI countries.Conclu-sion In 2021,the number of patients with AMD and DALYs in China ranked first in the world.The overall disease burden of AMD in China was between that of high-and low-SDI countries but was higher than global averages.The prevalence of AMD among people aged 55 years and above was significantly higher,and the burden was higher for females than for males.From 1990 to 2021,the number of patients with AMD and the prevalence of this disease in China exhibited an in-creasing trend,while those in low-,middle-,and high-SDI countries showed a decreasing trend.The overall DALYs in-creased,while the overall ASDR decreased.The gap in the AMD burden between high-income and low-income countries widened,and the burden was more severe in low-SDI countries.It was concluded that the burden of AMD was closely re-lated to age,gender,and SDI,and that its distribution characteristics and trends should be considered in the formulation of prevention and control strategies.

Objective To assess the global,regional,and national burdens of eye cancer between 1990 and 2021,examine its change trends with the age,sex,geographic location,and socio-demographic index(SDI)level,and provide scientific evidence for the development of eye cancer prevention and control strategies.Methods Based on the data from the Global Burden of Disease(GBD)study,the global burden of eye cancer was evaluated using the indicator system inclu-ding incidence,prevalence,mortality,and disability-adjusted life years(DALYs).The change trend of the burden of eye cancer with time was quantified with Join-point regression.Frontier analysis methods were used to evaluate the relationship between the burdens of eye cancer with SDI.Results From 1990 to 2021,the global incidence,age-standardized inci-dence rate(ASIR),prevalence and age-standardized prevalence rate(ASPR)of eye cancer showed an upward trend over time.Conversely,the mortality,age-standardized mortality rate(ASMR),DALYs,and age-standardized DALY rate(ASDR)declined during the same period.All the above indicators in males were higher than those in females.Regionally,Eastern Sub-Saharan Africa bore the highest disease burden,while Oceania had the lowest.It should be noted that East Asia experienced the most significant increase in ASIR,and Southern Sub-Saharan Africa showed the greatest rise in ASPR.Meanwhile,Southern Latin America demonstrated the most pronounced decrease in both ASIR and ASPR.East Asia also re-corded the largest reductions in ASMR and ASDR.At the national level,Malawi had the highest disease burden in 2021.To-kelau exhibited the most substantial increase while Norway showed the greatest decrease in disease burden.Age-specific analysis revealed a bimodal distribution,with children under 5 years and adults over 80 being the most affected groups.Furthermore,SDI-based analysis indicated a wave-like relationship between SDI and ASIR/ASPR,and both ASMR and AS-DR declined with the increasing SDI.Conclusion The global burden of eye cancer shows a decline trend generally.The difference in the burden of eye cancer between regional and national levels may be related to medical resource allocation and public health policies.The results of this study provide scientific evidence for the development of tailored eye cancer prevention and control strategies.It is recommended that more attention should be paid to high-burden regions,resource distribution should be optimized,early screening should be enhanced,and targeted interventions for different age and gen-der groups should be implemented.

ObjectiveTo explore the effects of different emulsion mixtures and emulsification methods on the inflammation severity in an experimental autoimmune uveitis （EAU） model in rats， and to analyze the characteristics of the current EAU model. MethodEAU was induced in Lewis rats by subcutaneous injection of interphotoreceptor retinoid-binding protein （IRBP） 1177-1191 emulsified with Freund's complete adjuvant （CFA）， with or without intraperitoneal injection of pertussis toxin （PTX）. Slit lamp examination， HE staining， and optical coherence tomography were used to evaluate factors affecting EAU modeling， including different doses of the emulsion mixture （IRBP1177-1191， PTX， and inactivated Mycobacterium tuberculosis） and four different emulsification methods. The classification， characteristics， modeling methods， advantages， and disadvantages of EAU animal models were summarized and analyzed based on the clinical diagnostic criteria and syndrome characteristics of chronic uveitis in both traditional Chinese medicine （TCM） and western medicine， to evaluate the consistency between TCM and western medical syndromes. ResultIncreasing the dose of inactivated M. tuberculosis and antigen peptide in the emulsion mixture exacerbated the anterior segment inflammation in EAU rats. Increasing the injection of PTX also exacerbated anterior segment inflammation and increased retinal thickness in EAU rats. The severity of the EAU model was closely related to the emulsification method used. All four emulsification methods successfully induced EAU in rats. Comparatively， the ultrasonic cell disruptor and T10 basic disperser achieved successful emulsification in a short time. The degree of emulsification of the mixture also influenced the severity of the EAU model in rats. The existing EAU animal model shows a high degree of consistency with western medical diagnoses and the main ocular syndromes in TCM. ConclusionIRBP1177-1191， PTX， inactivated M. tuberculosis， and emulsification methods can affect the severity of the EAU model through different pathways. The existing EAU animal models can simulate the clinical characteristics of western medicine well but lack the etiology， pathogenesis， and syndrome characteristics of TCM. Therefore， it is necessary to construct an EAU animal model that combines disease and syndrome characteristics.
