OBJECTIVE To investigate the improvement effects and mechanism of astragaloside Ⅳ (AS- Ⅳ ) on lipopolysaccharide (LPS)-induced neuroinflammation. METHODS BV2 cells were divided into control group, LPS group, AS-Ⅳ groups at concentrations of 20 and 40 μmol/L, and dexamethasone group (2 μmol/L). Except for control group, neuroinflammation model was established with LPS (1 μg/mL) in other groups after medication. The levels of inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and nitric oxide (NO)] in cell supernatant were measured in each group. Mice were randomly divided into normal group, model group, positive control group (Aspirin enteric-coated tablet, 20 mg/kg), AS-Ⅳ low- and high-dose groups (10, 20 mg/kg), with 6 mice in each group. Mice in each group were administered the corresponding drug/normal saline via gavage/intraperitoneal injection, once a day, for 14 consecutive days. Except for normal group, other groups were intraperitoneally injected with LPS (250 μg/kg) 1 hour after daily administration of the drug/normal saline to establish neuroinflammation model. Serum levels of IL-6 and TNF-α were measured 2 h after the last medication; histopathological morphology of cerebral tissue in mice were observed; the co-localization of inducible nitric oxide synthase (iNOS)/ionized calcium binding adapter molecule 1 (Iba1) and CD206/Iba1 in the cerebral cortex region of mice was observed; the expressions of proteins related to the nuclear factor-κB (NF-κB)/mitogen-activated protein kinase (MAPK) signaling pathway in brain tissue of mice were also determined, including NF-κB p65, phosphorylated NF-κB p65(p-NF-κB p65), p38 MAPK, phosphorylated p38 MAPK (p-p38 MAPK), extracellular signal-regulated kinase (ERK), and phosphorylated ERK (p-ERK). RESULTS In the cell experiments, compared with control group, the levels of IL-6, TNF- α and NO in the cell supernatant of the LPS group were increased significantly (P<0.05); compared with LPS group, the levels of IL-6, TNF-α and NO were decreased significantly in the administration groups (P<0.05). In the animal experiments, compared with the normal group, the serum levels of IL-6 and TNF- α, the number of iNOS/Iba1 co-localization positive cells in the cerebral cortex, and the phosphorylation levels of p38 MAPK, NF- κB p65 and ERK proteins in brain tissue were all significantly increased/elevated in model group (P<0.05); the number of CD206/ Iba1 co-localization positive cells in the cerebral cortex region significantly decreased (P<0.05). The neurons in the cerebral cortex and the CA3 region of the hippocampus displayed a disordered arrangement. Compared with model group, above quantitative indexes of mice were all reversed significantly in administration groups (P<0.05); the neuronal cells in the cerebral cortex and the CA3 region of the hippocampus exhibited a relatively orderly arrangement. CONCLUSIONS AS-Ⅳ may inhibit the activation of the NF-κB/MAPK signaling pathway, promote the M2-type polarization of microglia, and thereby suppress neuroinflammatory responses.

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.

ObjectiveTo analyze the results of opportunistic screening for upper gastrointestinal cancer in rural areas of Inner Mongolia Autonomous Region, so as to provide the evidence for optimizing prevention and control strategies for upper gastrointestinal cancer.
Methods:
Data on opportunistic screening for upper gastrointestinal cancer in rural areas of Inner Mongolia Autonomous Region from 2022 to 2024 were collected through the Opportunistic Screening Information Management System for Upper Gastrointestinal Cancer, including age, sex, mucosal staining, painless endoscopy, Helicobacter pylori (HP) test, HP test results, pathological examination results, and follow-up as well as treatment information. A descriptive analysis was conducted on the pathological examination results of opportunistic screening for upper gastrointestinal cancer in rural areas of Inner Mongolia Autonomous Region. The detection rate of upper gastrointestinal lesions and the early diagnosis rate of upper gastrointestinal cancer were compared among populations with different characteristics.
Results:
A total of 42 741 individuals were screened, including 20 856 males (48.80%) and 21 885 females (51.20%). The predominant age group was 50-<60 years, with 16 188 individuals (37.87%). Biopsy and pathological examination were performed in 15 355 individuals, with a biopsy rate of 35.93%. The main pathological findings were mild to moderate inflammation, accounting for 8 846 cases (57.61%). A total of 608 upper gastrointestinal lesions were detected, with a detection rate of 1.42%. The detection rate of upper gastrointestinal lesions showed an increasing trend with age (P<0.05). Individuals who were male, underwent mucosal staining, underwent HP testing, or had a positive HP test had higher detection rates of upper gastrointestinal lesions (all P<0.05). A total of 165 cases of early upper gastrointestinal cancer were detected, with an early diagnosis rate of 27.14%. The early diagnosis rate showed a decreasing trend with age (P<0.05). Individuals who were female or underwent mucosal staining had higher early diagnosis rates of upper gastrointestinal cancer (both P<0.05).
Conclusions
The detection rate of upper gastrointestinal lesions and the early diagnosis rate of upper gastrointestinal cancer in rural areas of Inner Mongolia Autonomous Region are relatively low. Males, elderly individuals, and HP-positive individuals are the key populations for screening.

OBJECTIVES:
To explore the bioactive components in Jiawei Xiaoyao Pills (JWXYP) and their mechanisms for alleviating depression-like behaviors.
METHODS:
The active compounds, key targets, and pathways of JWXYP were identified using TCMSP and TCMIP databases. Thirty-six SD rats were randomized equally into 6 groups including a control group and 5 chronic unpredictable mild stress (CUMS)-induced depression groups. After modeling, the 5 model groups were treated with daily gavage of normal saline, 1.8 mg/kg fluoxetine hydrochloride (positive control drug), or JWXYP at 1.44, 2.88, and 4.32 g/kg. The depression-like behaviors of the rats were evaluated using behavioral tests, and pathological changes in the liver and hippocampus were examined with HE staining. The biochemical indicators in the serum and brain tissues were detected using ELISA. Serum metabolomics analysis was performed to identify the differential metabolites using OPLS-DA, and gut microbiota changes were analyzed using 16S rDNA sequencing.
RESULTS:
Network pharmacology revealed that menthone and paeonol in JWXYP were capable of penetrating the blood-brain barrier to regulate inflammatory pathways and protect the nervous system. In the rat models subjected to CUMS, treatment with JWXYP significantly improved body weight loss, sucrose preference and open field activities, reduced liver inflammation, alleviated structural changes in the hippocampal neurons, decreased serum levels of TNF‑α, IL-1β, IL-6 and LBP, and increased 5-HT and VIP concentrations in the serum and brain tissue, and these effects were the most pronounced in the high-dose group. Metabolomics analysis showed changes in such metabolites as indole-3-acetamide and acetyl-L-carnitine in JWXYP-treated rats, involving the pathways for bile acid biosynthesis and amino acid metabolism. 16S rDNA analysis demonstrated increased gut microbiota diversity and increased abundance of Lactobacillus species in JWXYP-treated rats.
CONCLUSIONS
JWXYP alleviates depression-like symptoms in rats by regulating the neurotransmitters, inhibiting inflammation and oxidation, and modulating gut microbiota.

Objective:To investigate the clinical characteristics and prognosis of follicular lymphoma (FL) patients with different primary sites using the Surveillance, Epidemiology, and End Results (SEER) database.Methods:Clinical data of 7167 patients with early-stage FL (stage I-II) from the SEER database between 2000 and 2015 were respectively analyzed. Primary sites were divided into intranodal and extranodal types. Intranodal primary sites included supradiaphragmatic lymph nodes (LN), subphrenic lymph nodes and Waldeyer's ring. Extranodal primary sites consisted of skin, gastrointestinal tract, duodenum, head and neck, other sites. Prognostic factors and overall survival (OS) in patients with different primary sites were analyzed. OS rate was evaluated using Kaplan-Meier method and survival difference between primary sites was compared with log-rank test. Inverse probability treatment weighting (IPTW) and multi-variable analysis were applied to adjust for confounding factors. Multivariate Cox regression analysis of influencing factors of OS was performed.Results:The median age was 63 years old, with the median follow-up time of 63 months. There was no difference in prognosis among the intranodal groups or between the intranodal and extranodal groups. The 10-year OS rates of the supradiaphragmatic lymph LN ( n=2146), subdiaphragmatic LN ( n=2811), and the Waldeyer's ring ( n=151) groups were 70.7%, 69.9% and 73.4%, respectively ( P=0.422 for infradiaphragmatic LN vs. supradiaphragmatic LN, P=1.000 for Waldeyer's ring vs. supradiaphragmatic LN), and 70.3% and 68.9% for intranodal ( n=5108) and extranodal ( n=2059), respectively. There was no significant difference in OS between the groups ( P=0.581) after IPTW adjustment. The most common primary sites in extranodal disease were skin, gastrointestinal tract, head and neck, and duodenum. The 10-year OS for skin, gastrointestinal tract, and cutaneous was 74.2%, 74.7%, and 87.3%, respectively, significantly higher than 55.6% for other sites (duodenum vs. others sites, gastrointestinal vs. others sites, skin vs. others sites: all P<0.001). Multivariate Cox regression analysis revealed that difference in OS was not significant among the intranodal groups or between the intranodal and extranodal groups. However, different extranodal primary site was an independent prognostic factor for OS. Conclusions:Early FL patients with supradiaphragmatic LN, subdiaphragmatic LN and Waldeyer's ring, and between the intranodal and extranodal primary sites obtain similar prognosis. However, early-stage FL patients with different extranodal primary sites have prognostic differences. The prognosis of primary skin, gastrointestinal tract and duodenum is significantly better than that of other extranodal primary sites.

Flexible conductive fibers have been widely applied in wearable flexible sensing. However, exposed wearable flexible sensors based on liquid metal (LM) are prone to abrasion and significant conductivity degradation. This study presented a high-sensitivity LM conductive fiber with integration of strain sensing, electrical heating, and thermochromic capabilities, which was fabricated by coating eutectic gallium-indium (EGaIn) onto spandex fibers modified with waterborne polyurethane (WPU), followed by thermal curing to form a protective polyurethane sheath. This fiber, designated as Spandex/WPU/EGaIn/Polyurethane (SWEP), exhibits a four-layer coaxial structure: spandex core, WPU modification layer, LM conductive layer, and polyurethane protective sheath. The SWEP fiber had a diameter of (458.3 ± 10.4) μm, linear density of (2.37 ± 0.15) g/m, and uniform EGaIn coating. The fiber had excellent conductivity with an average value of (3 716.9 ± 594.2) S/m. The strain sensing performance was particularly noteworthy. A 5 cm × 5 cm woven fabric was fabricated using polyester warp yarns and SWEP weft yarns. The fabric exhibited satisfactory moisture permeability [(536.06 ± 33.15) g/(m 2·h)] and maintained stable thermochromic performance after repeated heating cycles. This advanced conductive fiber development is expected to significantly promote LM applications in wearable electronics and smart textile systems.

Objective:
To understand the distribution characteristics of high-risk populations for chronic obstructive pulmonary disease (COPD) among residents aged ≥40 years in Inner Mongolia Autonomous Region, so as to provide a basis for comprehensive prevention and control of COPD.
Methods:
A multi-stage stratified cluster random sampling method combined with probability proportional to size sampling was used to select residents aged ≥40 years from May to December 2019 in 4 monitoring sites in Inner Mongolia Autonomous Region for a questionnaire survey. Information on demographics, current or past smoking, severe respiratory infections in childhood, exposure to occupational harmful factors, exposure to indoor polluting fuels, chronic respiratory symptoms, personal history of chronic respiratory diseases, and family history of chronic respiratory diseases was collected. The distribution characteristics of high risk populations of COPD and high-risk factors were analyzed.
Results:
A total of 2 302 people were surveyed, including 1 234 males (53.61%) and 1 068 females (46.39%). The mean age was (57.87±8.67) years. A total of 2 114 people (91.83%) were exposed to at least one high-risk factor. The exposure rate of risk factors was 87.88%. There were significant differences in the exposure rates of risk factors among residents of different genders, ages, residence, and occupations (all P<0.05). The exposure rate was higher in males than in females, higher in the 50-60 years than in the 60-<70 years, higher in rural areas than in urban areas, and higher among those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy than among national enterprise clerks, professional and technical personnel, and retirees (all P<0.05). The prevalence of chronic respiratory symptoms was 14.73%. There were significant differences in the prevalence of chronic respiratory symptoms among residents of different residence and occupations (all P<0.05). The prevalence was higher in rural areas than in urban areas, and higher among those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy than among retirees (all P<0.05). The exposure rate of personal history of chronic respiratory diseases was 10.90%. There were significant differences in the exposure rate of personal history of chronic respiratory diseases among residents of different educational levels, residence, and occupations (all P<0.05). The exposure rate was higher among those with primary education or below and junior high school education than among those with high school education or above, higher in rural areas than in urban areas, and higher among those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy than among retirees (all P<0.05). The exposure rate of family history of chronic respiratory diseases was 22.85%. The exposure rate was higher in rural areas than in urban areas (P<0.05). Among residents exposed to risk factors, the exposure rate of current or past smoking was 38.84%, the exposure rate of severe respiratory infections in childhood was 2.13%, the exposure rate of occupational harmful factors was 44.27%, and the exposure rate of indoor polluting fuels was 60.12%. The exposure rates of current or past smoking and occupational harmful factors were higher in males and rural residents (all P<0.05).
Conclusions
The proportion of high-risk populations for COPD among residents aged ≥40 years in Inner Mongolia Autonomous Region is relatively high. It is recommended to strengthen health education for male residents, rural residents, and those engaged in agriculture, forestry, animal husbandry, fishery, and water conservancy, and to adopt comprehensive prevention and control strategies to reduce the exposure level of risk factors among residents.
