The dominant eye is the eye that plays a significant role in visual perception.It plays an essential role in binocular vision and fusion functions with a complex formation mechanism.According to the principle of the dominant eye examination method, ocular dominance can be classified into sighting, motor, and sensory dominance.Changes in visual acuity or visual function due to the unbalanced progression of binocular disease may lead to the switch in the dominant eye, affecting the balance of binocular vision and the therapeutic effect.Therefore, misjudging or neglecting of the dominant eye will change the long-term visual balance between the eyes, which may affect people's visual quality and quality of life.These aspects are mainly represented in the process of refractive error correction, refractive surgery, strabismus correction surgery, amblyopia training methods and cataract intraocular lens measurement.The formulation of medical plans based on the strategy of the dominant eye can remarkably improve the reconstruction good binocular vision and the quality of life of patients.However, the role of the dominant eye in binocular vision is not fully understood, and clinicians are not sufficiently aware of its importance.Therefore, this study will review the latest research progress on the mechanism of dominant eye formation, examination methods, and clinical significance of dominant eye switching.

Background:
SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood.
Methods:
We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival.
Results:
Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity.
Conclusions
The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

The dried rattan stem of the Fibraurea Recisa Pierre plant contains the active ingredient known as fibrauretine (FN). Although it greatly affects Alzheimer's disease (AD), the mechanism of their effects still remains unclear. Proteomics and transcriptomics analysis methods were used in this study to determine the mechanism of FN in the treatment of AD. AD model is used through bilateral hippocampal injection of Aβ1-40. After successful modeling, FN was given for 30 days. The results showed that FN could improve the cognitive dysfunction of AD model rats, reduce the expression of Aβ and P-Tau, increase the content of acetylcholine and reduce the activity of acetylcholinesterase. The Kyoto Encyclopedia of Genes and Genomes enriched differentially expressed genes and proteins are involved in signaling pathways including metabolic pathway, AD, pathway in cancer, PI3K-AKT signaling pathway, and cAMP signaling pathway. Transcriptomics and proteomics sequencing resulted in 19 differentially expressed genes and proteins. Finally, in contrast to the model group, after FN treatment, the protein expressions and genes associated with the PI3K-AKT pathway were significantly improved in RT-qPCR and Western blot and assays. This is consistent with the findings of transcriptomic and proteomic analyses. Our study found that, FN may improve some symptoms of AD model rats through PI3K-AKT signaling pathway.

Postoperative endophthalmitis (POE) is a serious vision-threatening complication of cataract surgery, with an incidence rate of 0.033%-0.11% in China.In recent years, numerous retrospective studies and data analyses have reported that intracameral injection of antibiotics can effectively reduce the incidence of bacterial endophthalmitis, which commonly include cefuroxime, vancomycin and moxifloxacin.Globally, due to factors such as the availability, cost-effectiveness, and types of pathogens of POE, the drug choice varies to a large extent.Adverse events caused by antibiotics in the intracameral injection often occur, including macular edema, retinal vascular leakage, and uveitis caused by overdose of cefuroxime, and complications such as hemorrhagic retinal vasculitis obliterans due to vancomycin.Moxifloxacin, as a fourth-generation fluoroquinolone, has a significant effect on the prevention of bacterial endophthalmitis.Studies in the past five years related to moxifloxacin, and the significant advantages of moxifloxacin in the prevention of bacterial endophthalmitis, drug safety, duration of intracameral drug, and cost-effectiveness were summarized in this article.

The progression of hyperuricemia disease is often accompanied by damage to renal function. However, there are few studies on hyperuricemia nephropathy, especially its association with intestinal flora. This study combines metabolomics and gut microbiota diversity analysis to explore metabolic changes using a rat model as well as the changes in intestinal flora composition. The results showed that amino acid metabolism was disturbed with serine, glutamate and glutamine being downregulated whilst glycine, hydroxyproline and alanine being upregulated. The combined glycine, serine and glutamate could predict hyperuricemia nephropathy with an area under the curve of 1.00. Imbalanced intestinal flora was also observed. , , , , and other conditional pathogens increased significantly in the model group, while and , the short-chain fatty acid producing bacteria, declined greatly. At phylum, family and genus levels, disordered nitrogen circulation in gut microbiota was detected. In the model group, the uric acid decomposition pathway was enhanced with reinforced urea liver-intestine circulation. The results implied that the intestinal flora play a vital role in the pathogenesis of hyperuricemia nephropathy. Hence, modulation of gut microbiota or targeting at metabolic enzymes, , urease, could assist the treatment and prevention of this disease.

Objective:
To identify and verify differentially expressed proteins in lens of nuclear cataract eyes with different axial lengths.
Methods:
Forty-eight nuclear cataract patients with the hardness grade Ⅲ to Ⅳ were enrolled from January 2016 to December 2017 in the east area of Xining city.The lens nucleus was obtained during extracapsular cataract extraction (ECCE) surgery.The samples were divided into six groups according to age and axial length, with 8 samples in each group.Seven normal transparent human lens nuclei were obtained from donors during corneal transplantation surgery and served as normal control.Water-soluble, water-insoluble and water-insoluble-urea-soluble protein fractions were extracted separately and merged to analyze by using 8-plex isobaric tags for relative and absolute quantitation (iTRAQ) labeling combined with 2D-LC/MS/MS.The data were processed with ProteinPilot software.Two technical replicates of iTRAQ analyses were carried out.Up-regulated and down-regulated proteins were selected in two replicates as candidate biomarkers.Twenty lens nuclei from 20 nulear cataract patients were divided into long axis young age group, normal axis young age group, long axis old age group and normal axis old age group.Western blot was used to confirm the most different proteins.This study protocol was approved by the Ethics Committee of TangDu Hospital of Air Force Medical University (TDLL2015046). Written consent was obtained from each participant.
Results:
Eighty proteins were identified.Six proteins were selected as differentially-expressed proteins.Sorbitol dehydrogenase (SDH) was elevated whereas beta-crystallin B2 (CRYBB2) was decreased in the long axis groups.The relative expression of SDH protein in the long axis low age group was 1.204±0.142, which was significantly higher than 0.711±0.072 in the normal axis low age group, the relative expression level of SDH in the long axis old age group was 1.092±0.334, which was significantly higher than 0.617±0.089 in the normal axis old age group, the difference was statistically significant (all at
