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.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by amyloid-β (Aβ) plaque deposition, neurofibrillary tangle (NFT) formation, and chronic neuroinflammation. Its global incidence and mortality continue to rise, yet effective curative therapies remain unavailable. In recent years, dysregulated cholesterol metabolism and immune-inflammatory responses have been increasingly recognized as key drivers of AD pathological progression. Both clinical and experimental studies have shown that patients with AD exhibit disrupted cholesterol homeostasis and aberrant T-cell function, with a significant correlation between these alterations, suggesting that cholesterol metabolic disturbances may participate in and amplify neuroinflammatory responses by modulating T-cell differentiation and activation states. This review systematically delineates the coupling relationship among cholesterol homeostasis imbalance, T-cell abnormalities, AD neuroinflammation, and related pathological injury. Specifically, we summarize the immunometabolic pathological links spanning the peripheral and central compartments, ranging from the effects of peripheral cholesterol metabolic disturbances on T-cell activation, differentiation, and blood-brain barrier permeability to the regulatory role of impaired brain cholesterol homeostasis in infiltrating T-cell inflammatory responses, glial activation, and neural microenvironment remodeling. We further highlight how abnormalities in cholesterol synthesis, transport, efflux, and oxidative product accumulation promote Th17/Treg imbalance, enhanced CD8+ T-cell effector activity, increased inflammatory cytokine release, as well as Aβ deposition, blood-brain barrier disruption, glial activation, and neuronal injury. In addition, we review recent progress in natural herbal formulas and bioactive phytochemicals that alleviate T-cell abnormalities and neuroinflammation through restoration of cholesterol homeostasis. Taken together, current evidence suggests that cholesterol homeostasis imbalance is not only a fundamental metabolic abnormality in AD, but may also construct and amplify AD neuroinflammation and related pathological injury by reshaping T-cell immunophenotypes. Therefore, immunometabolic intervention strategies aimed at restoring cholesterol homeostasis may provide a new theoretical basis for mechanistic studies and multi-target prevention and treatment of AD.

ObjectiveTo investigate the effect of schisanlactone E in ameliorating neuroinflammation and synaptic injury in APP/PS1 mice and to elucidate whether its mechanism is related to the regulation of helper T cell 17 (Th17)/regulatory T cell (Treg) immune balance. MethodsAPP/PS1 transgenic mice were assigned into model, low- and high-dose (2 mg·kg-1·d-1 and 4 mg·kg-1·d-1, respectively) schisanlactone E, and donepezil (1 mg·kg-1·d-1) groups. C57BL/6J mice were used as the control group. Each group received the corresponding drug by gavage for 30 days. Learning and memory abilities were assessed by the Morris water maze and novel object recognition tests. The percentages of Th17 and Treg cells in the peripheral blood were analyzed by flow cytometry. The mRNA levels of retinoid-related orphan receptor γt (RORγt), interleukin (IL)-17A, forkhead box protein 3 (FoxP3), and IL-4 in the hippocampus were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The synaptic ultrastructure in the hippocampus was observed by transmission electron microscopy. The protein levels of synapsin Ⅰ and postsynaptic density protein 95 (PSD95) in the hippocampus were measured by Western blot. Aβ aggregation and microglial activation in the hippocampus were observed by immunofluorescence staining. The mRNA levels of tumor necrosis factor (TNF)-α, IL-6, and IL-1β in the hippocampus were determined by Real-time PCR. ResultsCompared with the control group, the model group showed prolonged escape latency (P<0.05), decreased time spent in the target quadrant, platform crossings, novel object exploration time, and percentage of novel object contact frequency (P<0.05, P<0.01), increased Aβ aggregation in the hippocampal tissue (P<0.01), an increased proportion of Th17 cells (P<0.05), a decreased proportion of Treg cells (P<0.05), and an increased Th17/Treg ratio (P<0.01) in the peripheral blood. Furthermore, the hippocampal tissue in the model group exhibited upregulated mRNA levels of RORγt and IL-17A (P<0.05, P<0.01), downregulated mRNA levels of FoxP3 and IL-4 (P<0.01), decreased synapses (P<0.05), decreased PSD density, synaptic interface curvature, and active zone length (P<0.05, P<0.01), and increased synaptic cleft width (P<0.05), downregulated protein levels of Synapsin Ⅰ and PSD95 (P<0.01), increased microglial activation (P<0.01), and upregulated mRNA levels of TNF-α, IL-6, and IL-1β (P<0.05). Compared with the model group, the high-dose schisanlactone E group and the donepezil group exhibited shortened escape latency and increased time in the target quadrant and platform crossings (P<0.05, P<0.01). The schisanlactone E groups and the donepezil group showed increased novel object exploration time (P<0.05, P<0.01) and percentage of novel object contact frequency (P<0.05, P<0.01), and reduced hippocampal Aβ aggregation (P<0.05, P<0.01). The schisanlactone E groups showed a decreased proportion of Th17 cells (P<0.05) and an increased proportion of Treg cells (P<0.05) in the peripheral blood, and all treatment groups showed a decreased Th17/Treg ratio (P<0.05, P<0.01). The high-dose schisanlactone E group showed a downregulated mRNA level of RORγt in the hippocampal tissue (P<0.05), and all treatment groups showed a downregulated mRNA level of IL-17A (P<0.05, P<0.01), and upregulated mRNA levels of FoxP3 and IL-4 (P<0.05, P<0.01). The schisanlactone E groups and the donepezil group showed increased synapses, active zone length, synaptic interface curvature, and PSD density, decreased synaptic cleft width (P<0.05, P<0.01), and upregulated protein levels of synapsin Ⅰ and PSD95 (P<0.05, P<0.01). The high-dose schisanlactone E group and the donepezil group showed decreased microglial activation in the hippocampus (P<0.01). The schisanlactone E groups and the donepezil group showed downregulated mRNA levels of TNF-α, IL-6, and IL-1β in the hippocampal tissue (P<0.05, P<0.01). ConclusionSchisanlactone E significantly improves the cognitive function in APP/PS1 mice by regulating the Th17/Treg immune balance, inhibiting neuroinflammation, and ameliorating synaptic injury.

ObjectiveTo observe the effect of aspirin curcumin ester (CA) on the activation and glucose metabolism reprogramming of the mouse microglia (BV2) model of inflammation induced by high glucose/β-amyloid (Aβ)1-42, and to explore the potential mechanism of CA in reducing neuroinflammatory response in the brain. MethodsThe BV2 activation model was constructed by high glucose combined with Aβ1-42 oligomers. BV2 cells were treated with Aβ1-42 oligomers (10 μmol·L-1) in a high glucose (50 mmol·L-1) environment and allocated into normal, high glucose, Aβ, and high glucose + Aβ groups. The cell morphology of each group was observed under a bright field. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was adopted to assess the mRNA levels of inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) as well as glycolysis-related glucose transporter type 1 (GLUT1), hexokinase 2 (HK2), phospofructokinase-2/fructose-2,6-bisphosphatase 3 (PFKFB3), and pyruvate kinase M2 (PKM2). To reveal the effects of CA on inflammatory response and glucose metabolism in BV2 cells exposed to high glucose/Aβ1-42, this study established the BV2 cell model of inflammatory activation by high glucose and Aβ1-42 oligomer intervention. The cells were allocated into normal, model (50 mmol·L-1 glucose + 10 μmol·L-1 Aβ1-42), CA (10 μmol·L-1), 2DG (0.2 mmol·L-1), and DADA (1 mmol·L-1) groups. Cell counting kit-8 (CCK-8) was used to detect cell survival rate. The cell morphology of each group was observed under a bright field. The expression of inflammatory factors TNF-α, IL-6, and IL-1β and glycolysis-related key enzymes GLUT1, HK2, PFKFB3, and PKM2 at the mRNA level in each group was measured by real-time PCR. The protein levels of GLUT1, HK2, PFKFB3, and PKM2 were determined by Western blot. The glycolysis rate in each group was measured by seahorse. LC-MS was employed to identify the glucose metabolism intermediates. The morphology of mitochondria in cells was observed by electron microscopy. ResultsConstruction of the BV2 cell model: Compared with the normal group, the Aβ group and the high glucose + Aβ group showed more amoeboid-shaped cells and cell aggregation. The high glucose + Aβ group exhibited increased the mRNA levels of TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01), as well as those of key glycolytic enzymes GLUT1, HK2, PFKFB3, and PKM2 (P<0.01). The Aβ group also showed significantly increased mRNA levels of PKM2 and PFKFB3 (P<0.01). Effects of CA on the inflammatory response and glucose metabolism in BV2 cells exposed to high glucose/Aβ1-42: Compared with the normal group, the model group exhibited amoeboid-shaped cells and cell aggregation, upregulated mRNA levels of TNF-α, IL-1β, IL-6, iNOS, GLUT1, HK2, PFKFB3, and PKM2 (P<0.01) and protein levels of GLUT1, HK2, and PFKFB3 (P<0.05, P<0.01), an increased basal glycolysis rate (P<0.01), a decreased compensatory glycolysis rate (P<0.01), increased glycolytic intermediates and reduced TCA cycle intermediates. In addition, the mitochondria in the model group exhibited a decreased number (P<0.05), impaired crista integrity (P<0.01), an increased proportion of vacuolization (P<0.01), and abnormal mitochondrial morphology. Compared with those in the model group, the number of amoeboid-shaped BV2 cells reduced in the CA and 2DG groups, while most BV2 cells in the DADA group became elongated spindle-shaped. All the three treatment groups showed downregulated mRNA levels of TNF-α, IL-1β, IL-6, GLUT1, HK2, PFKFB3, and PKM2 (P<0.05, P<0.01), downregulated protein levels of GLUT1, HK2, and PFKFB3 (P<0.05, P<0.01), and slow compensatory glycolysis and basal glycolysis (P<0.05, P<0.01). Glycolytic intermediates were decreased and TCA cycle intermediates were increased in the CA and 2DG groups. Mitochondrial morphology largely returned to the normal level in all the three treatment groups, with an increase in mitochondrial number (P<0.05), improved crista integrity (P<0.05, P<0.01), and a decreased proportion of vacuolization (P<0.05). ConclusionAβ1-42 oligomers can activate BV2 cells and enhance glycolytic activity in the high glucose environment. CA can reduce the expression of inflammatory factors and inhibit the activation of BV2 cells by regulating the glucose metabolism reprogramming in BV2 cells.

ObjectiveTo investigate the effects of paeoniflorin (PF) on neuroinflammation and cognitive impairment in the rat model of Alzheimer's disease (AD) and to clarify whether its mechanism is associated with regulation of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. MethodsGlycosides related to AD-associated neuroinflammation were screened through bibliometric analysis, and the potential targets of PF were predicted through network pharmacology and molecular docking. A rat model of AD was established by intraperitoneal injection of D-galactose (100 mg·kg-1·d-1). Rats were assigned into a control group, a model group, a PF (200 mg·kg-1) group, and a donepezil (0.5 mg·kg-1·d-1) group, and drugs were administered by gavage for 21 days. The learning and memory abilities were evaluated by the Morris water maze (MWM). Hematoxylin-eosin (HE) staining and Nissl staining were performed to observe hippocampal neuronal morphology. The mRNA levels of inflammatory factors were determined by Real-time quantitative polymerase chain reaction (Real-time PCR), and the protein levels of molecules in the JAK2/STAT3 signaling pathway were determined by Western blot. ResultsCompared with the control group, the model group showed prolonged escape latency and decreased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), accompanied by increased expression of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α), as well as elevated ratios of phosphorylated (p)-JAK2/JAK2 and p-STAT3/STAT3 (P<0.01). Compared with the model group, the PF group and donepezil group exhibited shortened escape latency and increased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), decreased expression levels of IL-1β and TNF-α, upregulated mRNA levels of interleukin-4 (IL-4) and interleukin-10 (IL-10), and reduced ratios of p-JAK2/JAK2 and p-STAT3/STAT3 (P<0.05, P<0.01). ConclusionPaeoniflorin can alleviate cognitive impairment and neuroinflammation in the rat model of AD by inhibiting the JAK2/STAT3 signaling pathway.

ObjectiveTo explore the mechanism by which Buyang Huanwutang regulates the glutathione peroxidase 4 (GPX4)-acyl-CoA synthetase long-chain family member 4 (ACSL4) axis to inhibit ferroptosis and promote neurological functional recovery after spinal cord injury (SCI). MethodsNinety rats were randomly divided into five groups: sham operation group, model group, low-dose Buyang Huanwutang group (12.5 g·kg-1), high-dose Buyang Huanwutang group (25 g·kg-1), and Buyang Huanwutang + inhibitor group (25 g·kg-1 + 5 g·kg-1 RSL3). The SCI model was established by using the allen method. Tissue was collected on the 7th and 28th days after operation. Motor function was assessed by using the Basso-Beattie-Bresnahan (BBB) scale. Hematoxylin-eosin (HE), Nissl, and Luxol fast blue (LFB) staining were performed to observe spinal cord histopathology. Transmission electron microscopy was used to examine mitochondrial ultrastructure. Immunofluorescence staining was used to detect the number of NeuN-positive cells and the fluorescence intensity of myelin basic protein (MBP), GPX4, and ACSL4. Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) was used to analyze the mRNA expression of GPX4 and ACSL4. Enzyme linked immunosorbent assay (ELISA) was performed to measure the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD). Colorimetric assays were used to determine the iron content in spinal cord tissue. ResultsCompared to the sham operation group, the model group exhibited significantly reduced BBB scores (P<0.01), severe pathological damage in spinal cord tissue, and marked mitochondrial ultrastructural disruption. In addition, the model group showed a decrease in the number of NeuN-positive cells (P<0.01), reduced fluorescence intensity of MBP and GPX4 (P<0.01), lower levels of GSH and SOD (P<0.01), and downregulated mRNA expression of GPX4 (P<0.01). Moreover, compared to the sham operation group, the model group had elevated levels of ROS, MDA, and tissue iron content (P<0.01), along with increased fluorescence intensity and mRNA expression of ACSL4 (P<0.01). Compared with the model group and Buyang Huanwutang + inhibitor group, the Buyang Huanwutang group showed significantly improved BBB scores (P<0.05, P<0.01) and exhibited less severe spinal cord tissue damage, reduced edema and inflammatory cell infiltration, increased neuronal survival, and more intact myelin structures. Additionally, mitochondrial ultrastructure was significantly improved in the Buyang Huanwutang group. Compared to the model group and Buyang Huanwutang + inhibitor group, the Buyang Huanwutang group significantly increased the number of NeuN-positive cells and the fluorescence intensity of MBP (P<0.05, P<0.01). Furthermore, Buyang Huanwutang significantly increased the fluorescence intensity and mRNA expression of GPX4 (P<0.01) and decreased the fluorescence intensity and mRNA expression of ACSL4 (P<0.01) compared to the model group and Buyang Huanwutang + inhibitor group. Finally, the Buyang Huanwutang group significantly decreased ROS, MDA, and tissue iron content (P<0.01) and significantly increased GSH and SOD levels (P<0.01) compared to the model group and Buyang Huanwutang + inhibitor group. ConclusionBuyang Huanwutang inhibits ferroptosis through the GPX4/ACSL4 axis, reduces secondary neuronal and myelin injury and oxidative stress, and ultimately promotes the recovery of neurological function.

In recent years, there has been a significant surge in the prevalence of myopia at younger ages in China. Numerous studies have investigated methods for preventing and controlling myopia, including orthokeratology, low-concentration atropine eye drops, light therapy, posterior scleral reinforcement, and traditional Chinese medicine. These approaches can modulate choroidal thickness, blood flow, and target various molecular mechanisms. Orthokeratology and low-concentration atropine demonstrate a thickening effect on the choroid and regulate choroidal blood flow; the use of multi-point defocus control lenses also shows promise in thickening the choroid; the influence of light and light feeding therapy on myopia prevention and control is also reflected in the choroidal thickness and blood flow; and the traditional Chinese medicine has shown good prospect in influencing the microstructure of the choroid for myopia prevention and control. However, the long-term effects of various prevention and control measures on the choroid still need to be explored with a large sample size. This article provides an overview of various methods used to regulate the choroid and prevent myopia. The mechanisms by which these interventions act on the choroid are described to provide new insights and identity novel clinical strategies for myopia management.

Objective:To analyze the evaluation value of contrast-enhanced ultrasound (CEUS) combined with automatic volumetric ultrasound in the efficacy of neoadjuvant chemotherapy (NAC) for breast cancer.Methods:A retrospective study was conducted on 98 female patients with breast cancer admitted to Shaanxi Provincial Cancer Hospital from January to December 2022. All patients received 4 cycles of NAC, and underwent conventional ultrasound, automatic volumetric ultrasound, CEUS, and histopathological examination before and after treatment. Based on the post-treatment histopathological efficacy, patients were divided into the effective group ( n=67) and the ineffective group ( n=31). The CEUS and automatic volumetric ultrasound parameters before and after treatment, as well as the evaluation efficacy of these two types of parameters for NAC efficacy in breast cancer, were compared. The value of CEUS combined with automatic volumetric ultrasound in evaluating NAC efficacy for breast cancer was analyzed. Results:After NAC treatment, the CEUS parameters [time to peak (TTP) and arrival time (AT) of contrast agent] were longer than those before treatment, while the peak intensity (PI) was lower than that before treatment (all P<0.05); the automatic volumetric ultrasound parameters (tumor volume, area, thickness, length, and width) after NAC treatment were all smaller than those before treatment (all P<0.05). After treatment, the PI, volume, area, thickness, length, and width in the effective group were significantly smaller than those in the ineffective group, while the TTP and AT were significantly longer than those in the ineffective group (all P<0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of CEUS parameters and automatic volumetric ultrasound parameters for predicting effective NAC efficacy in breast cancer was 0.837(0.749-0.904) and 0.864(0.780-0.925), respectively, with no statistically significant difference between the two ( P=0.674). The AUC of the combined parameters for predicting effective NAC efficacy was 0.942(0.875-0.979), which was significantly higher than that of CEUS parameters or automatic volumetric ultrasound parameters alone ( Z=2.947, 2.135, P=0.003, 0.033). Conclusions:The combination of CEUS and automatic volumetric ultrasound parameters has high value in the efficacy evaluation of NAC for breast cancer and can be used as a clinical reference.
