After lentiviral transfection, MGC cells were divided into the THBS1 overexpression group and the control group. Proteins were extracted from both groups for 4D label-free quantitative proteomic analysis. Functional annotation of differentially expressed proteins (DEPs) and their regulated signaling pathways was performed via Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Real-time quantitative polymerase chain reaction (RT-qPCR) and Western blotting were used to validate the mRNA and protein expression levels of the top 5 DEPs. <b>Results:</b> Following successful THBS1 gene overexpression in MGC cells, 666 proteins were screened based on the criteria of |log₂(fold change)|>1.5 and <i>P<</i>0.05. GO analysis showed that DEPs were mainly localized in the cytosolic matrix and exosomes (cellular component), involved in RNA binding and cadherin binding (molecular function), and associated with translation and intracellular protein transport (biological process). KEGG pathway analysis indicated significant enrichment in DNA replication and cell cycle pathways. RT-qPCR results showed mRNA expression levels of asparagine-linked glycosylation 1 homolog (ALG1), AP2-associated protein kinase 1 (AAK1), Aladin WD repeat nucleoporin (AAAS), SUMO-specific peptidase 3 (SENP3), and Serrate RNA effector molecule homolog (SRRT) in the THBS1 overexpression group were 0.48±0.05, 0.83±0.04, 0.90±0.01, 0.73±0.06, and 0.92±0.02, respectively, significantly lower than those in the control group (1.00±0.03, 1.00±0.01, 1.00±0.03, 1.00±0.03, and 1.00±0.02; all <i>P<</i>0.05).

With explant culture for 1, 3, and 5 days, the expressions of GFAP (0.74±0.01, 0.70±0.04, 0.68±0.02), Vimentin (0.67±0.02, 1.91±0.09, 1.25±0.05), Iba1 (0.87±0.10, 2.36±0.13, 1.64±0.11), Bax (2.48±0.10, 0.37±0.02, 1.69±0.11), and C-caspase 3 (0.77±0.03, 2.49±0.09, 1.65±0.08) in the polydatin group were lower than those in the model group [GFAP (1.23±0.01, 1.17±0.01, 1.77±0.04), Vimentin (1.21±0.02, 2.67±0.06, 1.42±0.03), Iba1 (1.13±0.02, 3.51±0.07, 2.16±0.08), Bax (3.53±0.12, 1.27±0.06, 3.24±0.15), and C-caspase 3 (1.54±0.08, 3.38±0.17, 2.18±0.08)]. The expression of B-lymphocytoma-2 in the polydatin group (2.41±0.09, 1.67±0.07, 6.84±0.20) was higher than that in the model group (1.73±0.08, 0.96±0.07, 2.36±0.33). The differences were statistically significant (all <i>P<</i>0.05). In addition, the mRNA transcription levels of TNF-α (0.47±0.13, 12.07±0.56, 18.06±2.58) and IL-6 (0.55±0.12, 7.48±1.02, 41.35±7.08) in the polydatin group were lower than those in the model group [TNF-α (4.67±0.52, 26.62±2.62, 42.43±4.97) and IL-6 (1.21±0.06, 15.66±0.62, 67.46±3.78)]. The level of IL-10 (0.52±0.07, 2.98±0.24, 5.61±1.23) in the polydatin group was higher than that in the model group (0.06±0.03, 0.12±0.03, 2.64±0.74).

Databases including PubMed, Web of Science, Cochrane Library, Embase, and CNKI (from the establishment of the database to August 2023) were searched, and case-control studies comparing≥2 IOL formulas were included. The literature involves 12 intraocular lens (IOL) power calculation formulas, including Barrett Universal Ⅱ, EVO, Haigis, Hill RBF, Hoffer Q, Holladay 1, Kane, Olsen, PEARL DGS, SRK/T, T2, and VRF. The primary outcome measures were cases with prediction errors within the ranges of±0.25 D,±0.50 D, and ±1.00 D.Two researchers independently screened the literature, extracted data, and evaluated the risk of bias (using the QUADAS-2 tool). Traditional meta-analysis (fixed/random-effect model) was performed using RevMan 5.3, and network meta-analysis was carried out using Stata 14. The proportion of predictive errors within the ranges of ±0.50 D and ±1.00 D were the main indicators. The odds ratio (<i>OR</i>) and its 95% confidence interval (<i>CI</i>) were used to compare and evaluate the predictive error situations of different formulas. <b>Results:</b> A total of 8 studies (785 eyes) were included. Traditional meta-analysis showed that within the ±1.00 D range, Hoffer Q (93.4%; 648/694) and Kane (95.7%; 426/445) were significantly better than SRK/T (<i>OR=</i>1.50, 95%<i>CI</i>: 1.01-2.25, <i>P</i>=0.020; <i>OR</i>=2.00, 1.73-3.43, <i>P=</i>0.007). Kane was signifficantly better than T2 (<i>OR</i>=2.09, 1.15-3.80, <i>P</i>=0.020); within the ±0.50 D range, PEARL-DGS was better than SRK/T (<i>OR</i>=1.34, 1.00-1.80, <i>P</i>=0.050); within the ±0.25 D range, EVO (46.1%; 94/204) had the highest proportion and was significantly better than Hoffer Q (<i>OR</i>=0.62, 0.41-0.91, <i>P</i>=0.020). Network meta-analysis (ranked by the area under the cumulative ranking curve) indicated that EVO (ranked first within ±0.50 D) and Kane (ranked first within ±1.00 D) had the best overall performance, and SRK/T was the worst in all ranges <i>(P</i><0.05). <b>Conclusion:</b> Among the traditional optical refraction formulas, Haigis and Hoffer Q have good accuracy, and SRK/T is not recommended; the new-generation formulas (EVO, Kane) have better prediction accuracy in patients with short axial length and are recommended for clinical priority selection.</p>","PeriodicalId":39688,"journal":{"name":"中华眼科杂志","volume":"61 4","pages":"287-297"},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
