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.

AIM: To evaluate the reliability of a digital multimedia system for measuring near-distance horizontal heterophoria.METHODS: This cross-sectional diagnostic study enrolled patients with refractive errors who visited Shantou Aier Eye Hospital from May 2023 to August 2025, presenting with symptoms of visual fatigue, undergoing myopia management, or receiving routine ophthalmic examinations, and who completed heterophoria testing during this period. All patients wearing full refractive correction underwent near-distance(0.4 m)horizontal heterophoria measurement in a random order using the digital multimedia system, the Von Graefe method, and the Maddox rod method. Two consecutive measurements were performed for each method. The intraclass correlation coefficient(ICC)was used to analyze the measurement repeatability of each method, and Bland-Altman analysis and Spearman correlation analysis were employed to evaluate the consistency between the digital multimedia system and the two traditional methods.RESULTS: A total of 60 patients(120 eyes)were included, comprising 27 males and 33 females, with a mean age of 21.03±7.24 y. Repeatability analysis showed that the ICC for the digital multimedia system was 0.960(95%CI: 0.934-0.976), for the Von Graefe method was 0.979(95%CI: 0.964-0.987), and for the Maddox rod method was 0.956(95%CI: 0.926-0.973), all indicating excellent repeatability. Bland-Altman analysis revealed a mean difference of 0.367△ [95% limits of agreement(LoA): -2.97△ to 3.70△] between the Von Graefe method and the digital system, and a mean difference of 0.067△(95% LoA: -3.05△ to 3.19△)between the Maddox rod method and the digital system. Both differences were within the clinically acceptable range(difference <4△). Spearman correlation analysis showed positive correlations between the digital system and the Von Graefe method(rs=0.867)and between the digital system and the Maddox rod method(rs=0.777, all P<0.001).CONCLUSION: The digital multimedia system demonstrates high repeatability and good consistency with the traditional Von Graefe and Maddox rod methods for measuring near-distance horizontal heterophoria. It shows promise as a new and effective tool for clinical near-distance horizontal heterophoria measurement.

The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Objective To explore the value of diffusion tensor imaging analysis index along the perivascular space(DTI-ALPS)for assessing age-related functional changes in glymphatic system(GS).Methods Totally 27 healthy subjects from Meizhou People's Hospital and 100 healthy subjects from neuroimaging informatics tools and resources collaborator database who underwent T1-weighted magnetization-prepared rapid gradient echo(T1-MPRAGE)and DTI scanning were retrospectively enrolled and divided into youth group(n=38),middle-aged group(n=57)and elderly group(n=32).Automated DTI-ALPS index analysis procedure was used to minimize manual errors and derive DTI-ALPS index.The general data,neuropsychological assessment results and DTI-ALPS indices were compared among groups.Spearman correlation analysis was performed to observe the relationships of DTI-ALPS index and age,gender,as well as neuropsychological scores.Results The average age in youth group,middle-aged group and elderly group was(28.5±5.8),(53.7±6.8)and(73.8±2.3)years,respectively.No significant difference of DTI-ALPS index was found between middle-aged group and elderly group(P＞0.05),which were both lower than that in youth group(both P＜0.05).DTI-ALPS index was weakly negatively correlated with age(rs=-0.340,P＜0.001),but not significantly correlated with gender nor neuropsychological assessment results(both P＞0.05).Conclusion DTI-ALPS index was negatively correlated with age in healthy individuals,hence having potential utility for assessing age-related functional changes in GS.

Pathological interaction between CD4 + T cells and B cells is one of the important mechanisms of systemic autoimmune diseases. Follicular helper T cells (Tfh) and peripheral helper T cells (Tph) are key cells for assisting B cells. Tph cell is a newly discovered helper T cell subset, and their phenotype is PD-1 highCXCR5 -CD4 +. Tph cell and Tfh cell have certain differences in phenotype, function, and site of action. It interacts with B cells, promoting the differentiation of B cells into plasma cells and the production of autoantibodies, as well as promoting the formation of ELS to maintain local inflammation and antibody responses. Tph cells have recently been reported in various autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, Sjogren′s syndrome, and IgG4-related diseases. This review summarizes the progress in peripheral immune response of Tph cells in different systemic autoimmune diseases, aiming to explore the new mechanism of autoantibody production and help to develop new diagnostic and therapeutic targets in the future.

Objective To explore the change trajectory of self-acceptance of patients with permanent urostomy,in order to provide basis for self-acceptance intervention practice of patients.Methods 168 patients with abdominal wall stoma with urinary diversion from June 2021 to June 2023 in Fudan University Cancer Hospital were selected as the survey subjects by convenience sampling.We used a general information questionnaire,SAQ,PTGI,SSRS,and COST-PROM.Baseline surveys were conducted a week after surgery(T0),and follow-up surveys were conducted at 1 month(T1),3 months(T2),and 6 months(T3)after discharge.The mixed model of latent variable growth was used to analyze the change trajectory of self-acceptance of patients with permanent urinary stoma,and the core predictors of each subtype were explored through the decision tree model.Results The number of patients who participated in the 4 surveys was 168,168,165 and 163,respectively,and the final questionnaire recovery rate was 97.02％(163/168).The self-acceptance scores of patients with permanent urostomy were(35.72±8.63)(36.81±9.23)(39.88±8.95)and(43.17±9.56)points,respectively.The 3 subgroups of self-acceptance changes were identified,including low self-acceptance slow rising group(49.08％),medium self-acceptance first falling then rising group(30.06％),and medium self-acceptance fast rising group(20.86％)(P＜0.001).The decision tree model showed that education level,age,post-traumatic growth,social support,and economic burden could all predict the change track subtype of self-acceptance of patients with permanent urostomy,and the importance of post-traumatic growth was 100％.Conclusion The self-acceptance of patients with permanent urostomy is generally on the rise,and there is a population heterogeneity development track.Posttraumatic growth is the core predictor.It is important to identify the slow increase group of low self-acceptance according to the predictive indicators,and construct an intervention program focusing on improving the post-traumatic growth of patients with permanent urinary stoma to improve their self-acceptance level.

Objective:To evaluate the early-to-mid-term efficacy of supramalleolar osteotomy (SMO) in the treatment of traumatic ankle arthritis secondary to peri-ankle fracture.Methods:A retrospective study was conducted to analyze the clinical data of 29 patients who had been treated for traumatic ankle arthritis secondary to old peri-ankle fracture by SMO from March 2018 to March 2023 at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. There were 14 males and 15 females, 39.0 (25.0, 49.0) years in age. Types of old fracture: 4 lower tibiofibular fractures, 19 ankle fractures, and 6 pilon fractures. Surgery was conducted for 16 cases and conservative treatment for the remaining 13 cases. The interval between the old fracture and the current surgery was 10.0 (2.0, 19.5) years. The clinical efficacy was evaluated using the ankle-hindfoot score of American Association of Foot and Ankle Surgery (AOFAS), foot function index (FFI), and visual analog scale (VAS) pain score. Imaging analysis was conducted and imaging comparisons were made between pre-surgery and post-surgery in terms of tibial anterior surface (TAS) angle, tibial lateral surface (TLS) angle, talar tilt (TT) angle, and changes in modified Takakura staging. Complications were recorded. Surgical satisfaction was investigated at the final follow-up.Results:The 29 patients were followed up for 17.0 (14.0, 23.5) months. The AOFAS ankle-hindfoot score [(84.2±9.6) points], FFI [7.0 (3.0, 10.9) points], VAS pain score [2.0 (1.0, 3.0) points], and TAS angle [90.84° (86.70°, 92.50°)] at the final follow-up for all patients were significantly better than the pre-surgery values [(68.0±16.7) points, 20.9 (6.1, 29.1) points, 5.0 (2.0, 8.0) points, and 78.63° (74.30°, 85.00°)] (all P<0.05). At the final follow-up, the ankle arthritis grading did not show any significant change ( P>0.05) and there were no significant differences in TT angle or TLS angle between pre-surgery and post-surgery ( P>0.05). Incision failed to heal in 1 case, incision healing was delayed in 3 cases, and ankle arthritis progressed on imaging in 6 cases. As for patient self-assessed satisfaction, 23 cases felt very satisfactory, 4 cases quite satisfactory, and 2 cases common, giving an overall satisfaction rate of 93.1% (27/29). Conclusions:SMO has led to good early-to-mid-term efficacy in the treatment of traumatic ankle arthritis secondary to peri-ankle fracture, showing obvious pain relief and functional improvement after correction of the ankle joint alignment, limited postoperative complactions and a high rate of patient satisfaction.

Human keratinocyte growth factor-1 (hKGF-1), a member of the fibroblast growth factor (FGF) family, plays crucial roles in organ development, cell proliferation, wound healing, and tissue repair, representing one of the most effective and specific growth factors for skin repair. However, obtaining recombinant hKGF-1 remains challenging due to its universally low expression efficiency in vitro. This study employs the Bombyx mori baculovirus expression system to establish a technological platform that utilizes the economically important insect Bombyx mori as a bioreactor for high-efficiency and low-cost expression and production of recombinant human keratinocyte growth factor 1 (hKGF-1) protein, ultimately achieving high-level expression of hKGF-1 in Bombyx mori ovary cell line (BmN). In this study, we optimized the hKGF-1 sequence based on the codon preference of baculovirus. By fusing hKGF-1 with polyhedrin (highly expressed in this system) and adding extra promoters and enhancers, we significantly improved the expreesion level of hKGF-1 in Bombyx mori cells. The results demonstrated that the aforementioned strategies significantly enhanced the expression level of hKGF-1 in Bombyx mori cells. SDS-PAGE and Western blotting results revealed that the highest hKGF-1 expression (accounting for 8.7% of total cellular protein) was achieved when the Polh promoter was combined in tandem with the P6.9 promoter and hKGF-1 was fused with a 15-residue polyhedrin fragment for co-expression. The optimal harvest time was determined to be 120 h post transfection. This study achieved the efficient expression of hKGF-1 in Bombyx mori cells, establishing an ideal technological platform for the industrial utilization of recombinant hKGF-1. The developed methodology not only provides valuable technical references for the production of other growth factors and complex proteins, but also demonstrates significant implications for employing silkworms as bioreactors for recombinant human protein expression.

Bombyx mori nucleopolyhedrovirus (BmNPV) is extremely harmful to the silk industry. The polyhedrin, which encodes the polyhedrin (Polh), can be expressed at ultra-high levels and form occlusion bodies in the nucleus, embedding the progeny virus within it. However, the detailed mechanism by which polyhedrin is transported into the host cell nucleus remains unknown. Clarifying the nuclear import mechanisms of viral proteins can help us develop better prevention and treatment measures against baculoviruses. This study employed molecular cloning, co-immunoprecipitation, and immunofluorescence to analyze in detail the expression pattern of the highly expressed polyhedrin in the very late stage of the virus, and further revealed that the host protein importin α participates in the nuclear import of polyhedrin through protein interactions. This study provides a reference for further elucidating the nuclear import mechanisms of the baculovirus proteins including polyhedrin that can enter the nucleus.
