Intravitreal anti-vascular endothelial growth factor(anti-VEGF)therapy has been widely used, but the variability in its therapeutic efficacy limits individualized treatment. In recent years, the application of artificial intelligence(AI)has opened up new avenues for personalized treatment response prediction, and its core branches include machine learning(ML)and deep learning(DL). This review systematically retrieved and analyzed 41 relevant studies published up to April 2025. Comprehensive analysis reveals that AI predictive models are evolving from forecasting single endpoints(such as visual acuity or central retinal thickness)to integrating multi-dimensional endpoints(encompassing anatomical, functional, and treatment demand parameters)and generating predictive imaging outputs. In terms of technical approaches, DL models(28 studies, accounting for 68.3%)dominate this field due to their robust image interpretation capabilities, while ML models(10 studies, 24.4%)retain significant value in the analysis of structured clinical data. Cross-disease comparisons indicate that research efforts are most concentrated on age-related macular degeneration(ARMD)and diabetic macular edema(DME), with shared conceptual frameworks for model construction, yet distinct anatomical and functional indicators are prioritized for each disease. Currently, the field confronts several key challenges, including insufficient prospective clinical validation, limited model interpretability(the “black box problem”), and a scarcity of high-quality multi-center datasets. Moving forward, it is imperative to advance real-world validation and develop explainable AI techniques to expedite the clinical translation of these predictive models.

OBJECTIVES: The aim of this study is to determine the effect of cannabinoid receptor (CB) 2 inhibitor on desmoglein 3 (DSG3) expression in HaCaT cells co-cultured with pemphigus serum. METHODS: Immunohistochemical staining was used to compare CB expression in pemphigus patients and normal individuals. Enzyme-linked immunosorbent assay (ELISA) was employed to quantify the concentration of CB2 in the serum of pemphigus patients and normal individuals. A correlation analysis was performed to examine the relationship between the serum CB2 and DSG of pemphigus patients. The CCK-8 assay was used to evaluate the inhibitory effect of AM630 on HaCaT cells, and the half-maximal inhibitory concentration (IC₅₀) value was utilized to determine the experimental concentration. Serum from normal individuals (negative control group) and pemphigus patients (pemphigus group) was co-cultured with HaCaT cells at a 1∶1 ratio. HaCaT cells cultured in complete medium were used as the control group. HaCaT cells in the pemphigus group treated with AM630 were employed as the AM630 group. Real-time polymerase chain reaction (PCR) and Western blot were conducted to assess the expression levels of CB2, DSG3, and β-catenin. Cell dissociation experiments were conducted to evaluate the effect of AM630 on the adhesion of HaCaT cells. RESULTS: Immunohistochemistry revealed significant differences in CB2 expression between pemphigus and normal mucosa (P<0.000 1), but no difference was found in CB1 expression. ELISA analysis revealed a statistically significant difference in the expression levels of CB2 in the serum between normal individuals and pemphigus patients (P<0.001). The expression of CB2 in the serum of pemphigus patients exhibited a significant positive correlation with that of DSG3 (r=0.831, P=0.003). The CCK-8 assay indicated that the IC₅₀ of AM630 on HaCaT cells was 0.55 μmol/L. Real-time PCR and Western blot showed that the expression levels of CB2 and DSG3 increased in the pemphigus group, while the expression level of β-catenin decreased compared with that in the AM630 groups (P<0.05). CONCLUSIONS CB2 is highly expressed in oral mucosal pemphigus. AM630 inhibits overexpression of CB2 and DSG3 and underexpression of β-catenin levels, which can provide new therapeutic targets for pemphigus.

The prevalence of summer endogenous fever is closely related to the climate of summer.Based on Li Dongyuan's yin-fire theory,this article proposed that summer-heat,irregular diet,excessive consumption of cold foods,poor living habits,and summer damp-heat internal invasion damaging the spleen can all lead to the generation of yin-fire,thereby causing endogenous fever.The core pathogenesis of summer endogenous fever lies in spleen deficiency with yang collapse,which results into the blockage of qi movement and the production of yin-fire.The yin-fire persists throughout the entire course of the disease.Treatment of summer endogenous fever should focus on eliminating yin-fire,primarily by addressing the spleen via boosting qi and raising yang to restore the spleen's ascending and stomach's descending functions,thereby dispersing yin-fire.Clearing heat and resolving dampness can purge yin-fire and then the spleen qi's circulation is restored.By analyzing the pathological changes of dampness accumulation into phlegm,fire-heat damaging yin and liver stagnation with kidney deficiency,the disease progression can be predicted.Correspondingly,comprehensive therapy of resolving phlegm,nourishing yin,soothing liver,and tonifying kidney can be employed to prevent further deterioration.Based on Li Dongyuan's yin-fire theory,Shengyang Yiwei Decoction(mainly composed of Astragali Radix,Pinelliae Rhizoma,Ginseng Radix et Rhizoma,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Angelicae Pubescentis Radix,Saposhnikoviae Radix,Paeoniae Radix Alba,Notopterygii Rhizoma et Radix,Citri Reticulatae Pericarpium,Poria,Bupleuri Radix,Alismatis Rhizoma,Atractylodis Macrocephalae Rhizoma,and Coptidis Rhizoma)can be used as a fundamental prescription to treat summer endogenous fever caused by yin-fire,with modifications tailored to specific clinical presentations.This theoretical exploration may provide a reference for the clinical management of summer endogenous fever.

Objective To systematically search,evaluate,and summarize the evidence for risk management of breast and ovarian cancers in carriers of breast cancer susceptibility gene 1/2(BRCA1/2)mutations.Methods A systematic search was conducted in BMJ Best Practice,UpTo-Date,the National Guideline Clearinghouse(NGC),the National Institute for Health and Care Ex-cellence(NICE),the Scottish Intercollegiate Guidelines Network(SIGN),the Guidelines Interna-tional Network(GIN),the New Zealand Guidelines Group(NZGG),the Canadian Medical Associa-tion Infobase(CMA InfoBase),the Registered Nurses' Association of Ontario(RNAO),the National Comprehensive Cancer Network(NCCN),Cancer Care Ontario(CCO),the Medlive website,the American Society of Clinical Oncology(ASCO),the European Society for Medical Oncology(ESMO),the American Cancer Society(ACS),the American College of Obstetricians and Gynecologists(ACOG),the Joanna Briggs Institute(JBI),the Cochrane Library,PubMed,Web of Science,Em-base,CINAHL,ProQuest,ClinicalTrials.gov,China National Knowledge Infrastructure,Wanfang Data,VIP Database,and SinoMed for evidence related to risk management of breast and ovarian canc-ers in BRCA1/2 mutation carriers,including clinical decisions,guidelines,systematic reviews,expert consensus,and evidence summaries.The search period was from the inception of each database to September 20,2024.Results A total of 14 articles were included,comprising 1 clinical decision,8 guidelines,and 5 expert consensus documents.Based on five themes-risk assessment,risk moni-toring,risk-reducing surgery,pharmacologic prevention,and health guidance,a total of 24 pieces of evidence were summarized.Conclusion The evidence summarization process in this study is standardized,and the summarized evidence is relatively comprehensive.Healthcare professionals should comprehensively consider patients' individual characteristics,family history,personal prefer-ences,and the accessibility of healthcare resources to achieve effective prevention and control of he-reditary tumor risks.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

Objective To investigate the association of triglyceride-glucose index(TyG)with non-alcoholic fatty liver disease(NAFLD)and its diagnostic value for NAFLD in non-obese individuals.Methods We retrospectively collected the data of non-obese individuals(BMI<25 kg/m2)undergoing routine health examination at Second Affiliated Hospital of Xi'an Jiaotong University between May,2020 and December,2023,who all received abdominal ultrasound examination for NAFLD screening.The nonlinear relationship between TyG and non-obese NAFLD was explored using restricted cubic splines(RCS),and LASSO regression was used for variable screening;the correlation between TyG and NAFLD risk was analyzed using multivariate logistic regression.The diagnostic value of TyG for non-obese NAFLD was assessed using receiver-operating characteristic(ROC)curves and sensitivity analysis.Results A total of 3723 non-obese subjects were enrolled in this study,including 432(11.6%)patients with NAFLD.Compared with the healthy individuals,the patients with NAFLD had significant elevations of systolic and diastolic blood pressures,total cholesterol,triglycerides,LDL-C,blood uric acid,fasting blood glucose,and TyG index and a decreased HDL-C level(P<0.05).Multivariate logistic regression revealed that for each one-unit increase of TyG,the risk of non-obese NAFLD increased by 2.2 folds(OR=3.22,95%CI:2.53-4.12,P<0.001).Compared with a TyG index in the lowest quartile Q1,a TyG index in the Q2,Q3 and Q4 quartiles was associated with an increased risk of NAFLD by 1.52 folds(OR=2.52,95%CI:1.20-5.95),3.56 folds(OR=4.56,95%CI:2.28-10.46),and 8.66-folds(OR=9.66,95%CI:4.83-22.18),respectively.The RCS curve demonstrated a significant linear correlation between TyG index and non-obese NALFD risk(P for nonlinear=0.019).For diagnosing non-obese NALFD,TyG index had an area under ROC curve of 0.819 with a sensitivity of 78.0%and a specificity of 71.2%.Conclusion An increase of TyG index is correlated with increased risks of NAFLD in non-obese individuals and can serve as an indicator for screening early NAFLD in healthy individuals.

Objective To investigate the relationship between the expression levels of serum microRNA-181a(miR-181a)and sphingosine 1-phosphate receptor 1(S1PR1)messenger RNA(mRNA)and the occur-rence of acute exacerbation in patients with bronchial asthma.Methods From January 2021 to May 2023,a to-tal of 132 patients with bronchial asthma in acute exacerbation stage from Shijiazhuang Emergency Center were selected as the acute stage group,89 patients with bronchial asthma in remission stage were selected as the remission stage group and 90 healthy personnel for physical examination were selected as the control group.The acute stage group was divided into mild group(50 cases),moderate group(45 cases)and severe group(37 cases).Clinical data were collected and pulmonary function[ratio of forced expiratory volume to forced vital capacity in the first second(FEV1/FVC)and percentage of peak expiratory flow rate to expected value(PEF％pred)]was examined.Real-time fluorescence quantitative PCR was used to detect the serum miR-181a and S1PR1 mRNA expression.Pearson method was used to analyze the correlation between serum miR-181a and S1PR1 mRNA and lung function indicators in patients with acute exacerbation of bronchial asthma.Multivariate Logistic regression analysis was used to identify factors affecting the occurrence of acute exacerbation in patients with bronchial asthma.Receiver operating characteristic(ROC)curve was used to e-valuate the value of serum miR-181a and S1PR1 mRNA in predicting the occurrence of acute exacerbation in patients with bronchial asthma.Results The FEV1/FVC,PEF％pred and relative expression level of serum miR-181a in control group,remission stage group and acute stage group were decreased successively,while the relative expression level of S1PR1 mRNA were increased successively(P＜0.05).The relative expression lev-el of serum miR-181a in mild group,moderate group and severe group was decreased successively,and the rel-ative expression level of S1PR1 mRNA was increased successively(P＜0.05).In patients with acute exacer-bation of bronchial asthma,serum miR-181a and S1PR1 mRNA were negatively correlated(P＜0.05),serum miR-181a was positively correlated with FEV1/FVC,PEF％pred(P＜0.05),and serum S1PR1 mRNA was negatively correlated with FEV1/FVC,PEF％pred(P＜0.05).Low level of FEV1/FVC,low level of PEF％pred,low relative expression level of miR-181a and high relative expression level of S1PR1 mRNA were inde-pendent risk factors affecting the occurrence of acute exacerbation in patients with bronchial asthma(P＜0.05).The area under the curve(AUC)of the combination of serum miR-181a and S1PR1 mRNA for predic-ting the acute exacerbation in patients with bronchial asthma was 0.890,which was higher than the AUC of the two predicted alone(P＜0.05).Conclusion The serum miR-181a in patients with bronchial asthma is lowly expressed,while S1PR1 mRNA is highly expressed.Both are related to the occurrence and severity of acute exacerba-tion as well as lung function,and have high predictive efficacy for the occurrence of acute exacerbation.
