OBJECTIVE To evaluate the therapeutic effects and safety of everolimus combined with letrozole and conventional chemotherapy for metastatic or recurrent endometrial carcinoma （EC）. METHODS The clinical and follow-up data of 156 patients with metastatic or recurrent EC admitted to Nanyang Central Hospital from January 2020 to January 2024 were analyzed retrospectively. They were divided into a control group （77 cases） and an observation group （79 cases） according to different therapeutic regimens. The control group received paclitaxel+carboplatin/cisplatin regimen， and concurrently took Letrozole tablets at a dose of 2.5 mg orally once daily； the observation group took Everolimus tablets 10 mg orally， once a day， in addition to the treatment regimen given to the control group. Each treatment cycle lasted 21 days， and both groups of patients underwent continuous treatment for 6 to 8 cycles. The short-term efficacy indicators （objective response rate and disease control rate）， the levels of serum tumor markers [carbohydrate antigen 125， human epididymis protein 4， vascular endothelial growth factor and matrix metalloproteinase-9] and medium- to long-term efficacy indicators [progression-free survival （PFS） and overall survival （OS）] were compared between the two groups. Additionally， the occurrence of toxic and side effects in both groups of patients was recorded. RESULTS The objective response rate （53.16%）， disease control rate （89.87%）， median PFS （6.47 months） and median OS （10.79 months） of the observation group were significantly higher or longer than those （22.08%， 68.83%， 4.63 months， 8.84 months） of the control group （P＜0.05）. Compared with before treatment， the levels of serum tumor markers in both groups decreased significantly after 6 cycles of treatment； the above indexes of the observation group were significantly lower than those of the control group （P＜0.05）. The proportion of patients with stomatitis in the observation group was significantly higher than that of the control group （P＜0.05）， and there was no statistically significant difference in the proportions of patients experiencing other toxic and side effects， such as leukopenia， between the two groups （P＞0.05）. CONCLUSIONS The everolimus combined with letrozole and conventional chemotherapy can effectively improve the short-term efficacy and prolong the survival period in patients with metastatic or recurrent EC， but attention should be paid to the occurrence of toxic and side effects， especially stomatitis.

Establishing a three-generation family cohort enables the investigation of the effects of genetic, epigenetic, lifestyle, and parenting factors in the grandparental (F0) and parental (F1) generations on the growth, development, and disease onset and progression of the offspring (F2). It facilitates further exploration of the biological mechanisms underlying the impact of intergenerational factors on the health of the offspring (F2), providing evidence for the formulation of public health policies and measures related to child health management and infant and young child care. Currently, the development of multi-generational cohorts in China remains in a preliminary stage, with no systematic multi-generational research framework yet established. Drawing on prior evidence-based scientific research, existing cohort studies, and the practical experience of multidisciplinary experts in maternal and child health, this consensus defines the scope of three-generation family cohorts regarding their definition, significance, key technologies, and application scenarios. It provides technical recommendations for establishing relevant cohorts, aiming to support research areas such as the intergenerational transmission of childhood diseases, the maternal intrauterine environment, and the tracing of family rearing environments. This will facilitate the early prevention and control of diseases manifesting in childhood and adulthood, ultimately promoting the comprehensive and healthy development of children.

Functional dyspepsia （FD） is a prioritized disease category where traditional Chinese medicine （TCM） demonstrates distinct therapeutic advantages. The current western medicine treatment for FD is mainly based on proton pump inhibitors and prokinetic agents， with digestive enzymes， probiotics and antidepressants serving as adjuvant medication， yet such therapies still have certain limitations. TCM treatment for FD includes oral administration of Chinese herbal formulas and Chinese patent medicines， as well as external TCM therapies such as acupuncture and moxibustion， acupoint application， hot medicinal compress therapy， rubbing with ointment， medicinal iontophoresis， auricular acupoint therapy and tui na （Chinese medical massage）. The combined treatment of FD with integrated TCM and western medicine can significantly improve clinical effectiveness and reduce adverse reactions. The common mechanisms underlying the therapeutic effects of both TCM and western medicine revolve around the core pathological processes of FD， mainly focusing on restoring gastrointestinal motility， regulating the levels of brain-gut peptides， modulating intestinal microecology， and ameliorating inflammatory status. The differential mechanisms lie in the precise targeting feature of western medicine versus the holistic-regulating and multi-target characteristics of TCM， and the two approaches exert a synergistic effect to enhance efficacy. This paper proposes to leverage the advantages of TCM in holistic regulation and the strengths of western medicine in targeted treatment， so as to provide personalized and comprehensive treatment regimens for FD patients.

Objective To explore whether there is a causal relationship between intestinal flora and esophageal cancer. Methods Summary statistics of intestinal flora and esophageal cancer were obtained from the Genome-wide Association Studies (GWAS) database. Five methods, including inverse variance weighted (IVW), weighted median estimation, Mendelian randomization (MR)-Egger regression, single mode, and weighted mode, were used for analysis, with IVW as the main analysis method. Sensitivity analysis was used to evaluate the reliability of MR results. Results In the IVW method, Oxalobacteraceae [OR=1.001, 95%CI (1.000, 1.002), P=0.023], Faecalibacterium [OR=1.001, 95%CI (1.000, 1.002), P=0.028], Senegalimassilia [OR=1.002, 95%CI (1.000, 1.003), P=0.006] and Veillonella [OR=1.001, 95%CI (1.000, 1.002), P=0.018] were positively correlated with esophageal cancer, while Burkholderiales [OR=0.999, 95%CI (0.998, 1.000), P=0.002], Eubacterium oxidoreducens [OR=0.998, 95%CI (0.997, 0.999), P=0.038], Romboutsia [OR=0.999, 95%CI (0.998, 1.000), P=0.048] and Turicibacter [OR=0.998, 95%CI (0.997, 0.999), P=0.013] were negatively correlated with esophageal cancer. Sensitivity analysis showed no evidence of heterogeneity, horizontal pleiotropy and reverse causality. Conclusion Oxalobacteraceae, Faecalibacterium, Senegalimassilia and Veillonella increase the risk of esophageal cancer, while Burkholderiales, Eubacterium oxidoreducens, Romboutsia and Turicibacter decrease the risk of esophageal cancer. Further studies are needed to explore how these bacteria affect the progression of esophageal cancer.

Objective: To develop a dual-branch deep learning framework for accurate multi-label classification of fundus diseases, addressing the key limitations of insufficient complementary feature extraction and inadequate cross-modal feature fusion in existing automated diagnostic methods. Methods: The fundus multi-label classification dataset with 12 disease categories (FMLC-12) dataset was constructed by integrating complementary samples from Ocular Disease Intelligent Recognition (ODIR) and Retinal Fundus Multi-Disease Image Dataset (RFMiD), yielding 6 936 fundus images across 12 retinal pathology categories, and the framework was validated on both FMLC-12 and ODIR. Inspired by the holistic multi-regional assessment principle of the Five Wheels theory in traditional Chinese medicine (TCM) ophthalmology, the dual-branch multi-label network (DBMNet) was developed as a novel framework integrating complementary visual feature extraction with pathological correlation modeling. The architecture employed a TransNeXt backbone within a dual-branch design: one branch processed red-green-blue (RGB) images to capture color-dependent features, such as vascular patterns and lesion morphology, while the other processed grayscale-converted images to enhance subtle textural details and contrast variations. A feature interaction module (FIM) effectively integrated the multi-scale features from both branches. Comprehensive ablation studies were conducted to evaluate the contributions of the dual-branch architecture and the FIM. The performance of DBMNet was compared against four state-of-the-art methods, including EfficientNet Ensemble, transfer learning-based convolutional neural network (CNN), BFENet, and EyeDeep-Net, using mean average precision (mAP), F1-score, and Cohen's kappa coefficient. Results: The dual-branch architecture improved mAP by 15.44 percentage points over the single-branch TransNeXt baseline, increasing from 34.41% to 44.24%, and the addition of FIM further boosted mAP to 49.85%. On FMLC-12, DBMNet achieved an mAP of 49.85%, a Cohen’s kappa coefficient of 62.14%, and an F1-score of 70.21%. Compared with BFENet (mAP: 45.42%, kappa: 46.64%, F1-score: 71.34%), DBMNet outperformed it by 4.43 percentage points in mAP and 15.50 percentage points in kappa, while BFENet achieved a marginally higher F1-score. On ODIR, DBMNet achieved an F1-score of 85.50%, comparable to state-of-the-art methods. Conclusion DBMNet effectively integrates RGB and grayscale visual modalities through a dual-branch architecture, significantly improving multi-label fundus disease classification. The framework not only addresses the issue of insufficient feature fusion in existing methods but also demonstrates outstanding performance in balancing detection across both common and rare diseases, providing a promising and clinically applicable pathway for standardized, intelligent fundus disease classification.

Autoimmune hepatitis （AIH） is an immune-mediated chronic liver inflammatory disease with unknown pathogenesis， and intestinal barrier dysfunction is considered an important factor. Meanwhile， there are sex and age differences in the incidence rate of AIH， suggesting that hormone may be involved in regulation. On this basis， this article focuses on the association between estrogen， intestinal barrier， and immune homeostasis， systematically reviews the evidence that estrogen deficiency disrupts intestinal barrier homeostasis， and further summarizes the potential mechanism of estrogen in regulating the development and progression of AIH via intestinal barrier.

OBJECTIVE To explore the characteristics of the transient bilateral blindness caused by Iodixanol injection， analyze its occurrence mechanism， risk factors and treatment strategies， and provide references for the safe clinical use of Iodixanol injection. METHODS A retrospective analysis was conducted on the clinical data of a patient with bilateral vertebral artery stenosis who experienced transient bilateral blindness after receiving Iodixanol injection for interventional treatment. Based on this， combined with relevant literature from both domestic and international sources， a systematic analysis was carried out from aspects such as the correlation of adverse reactions， the mechanism of occurrence， risk factors， clinical characteristics， and treatment measures. RESULTS The patient received approximately 150 mL of Iodixanol injection during the operation. Blurred vision occurred 2 hours after the procedure， which gradually progressed to no light perception in both eyes， accompanied by headache， fever and transient renal dysfunction. According to the criteria for causality assessment of adverse drug reactions， the association between Iodixanol injection and transient bilateral blindness was assessed as “probable”. Combined with analysis of the present case and relevant literature， the underlying mechanisms were speculated to be related to blood-brain barrier disruption， immune reactions and microembolism. Risk factors included underlying cerebrovascular disease， renal insufficiency， high dose of contrast medium and atopic constitution. This adverse reaction was characterized by an acute onset， complex symptoms and obvious reversibility. After symptomatic treatments such as dehydration， anti-allergy therapy， fluid infusion and diuresis， as well as neurotrophic therapy， the patient’s vision recovered completely on the 5th day after surgery， and renal function also returned to the preoperative levels. CONCLUSIONS Transient bilateral blindness induced by Iodixanol injection is rare but clinically severe. At present， its exact pathogenesis has not been fully elucidated， and it involves a variety of risk factors. Before clinical administration， it is necessary to comprehensively evaluate the patient’s underlying diseases， renal function and allergy history； control the dosage of contrast medium during the operation； and closely monitor the patient’s condition after surgery. Once adverse reactions occur， timely intervention should be taken to improve the prognosis.

ObjectiveTo explore the effect and mechanism of Taishan Panshi powder （TSPSP） on inhibiting oxidative stress injury in human chorionic trophoblast cells （HTR-8/SVneo）， and to uelucidate the underlying mechanism of TSPSP in the treatment of spontaneous abortion （SA）. MethodsGene differential analysis of SA was performed using the Gene Expression Omnibus （GEO） database and correlated with oxidative stress. Network pharmacology was employed to screen the active components of TSPSP， and a "Chinese medicine-component-target-disease" network was constructed to predict the mechanism of action of TSPSP. For in vitro validation experiments， HTR-8/SVneo cells were divided into blank group， model group， TSPSP-containing serum 2.5%， 5%， 10% groups， and nuclear factor E₂-related factor 2 （Nrf2） inhibitor group （ML385， 30 μmol·L^-1）. Except for the blank group， other groups were stimulated with 150 μmol·L^-1 H₂O₂ for 3 h to establish a cell oxidative stress injury model. After successful modeling， the blank group and model group were given 10% blank serum， each TSPSP-containing serum group was treated with the corresponding concentration of drug-containing serum， and the Nrf2 inhibitor group was additionally given 30 μmol·L^-1 ML385 on the basis of 10% TSPSP-containing serum. All groups of cells were continuously cultured under the above conditions for 24 h， and then samples were collected for subsequent detection. Cell viability in each group was detected by CCK-8 assay. Cell migration rate was detected by scratch test. The contents of malondialdehyde （MDA）， Fe²⁺， and Glutathione （GSH） were detected by enzyme-linked immunosorbent assay （ELISA）. Intracellular reactive oxygen species （ROS） level was detected by a fluorescent probe （DCF-DA）. The protein and mRNA expression levels of Kelch-like ECH-associated protein 1 （KEAP1）， Nrf2， and forkhead box protein O3 （FoxO3） in cells were detected by immunofluorescence （IF） and real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of KEAP1， Nrf2， FoxO3， Glutathione peroxidase 4 （GPX4）， and superoxide dismutase （SOD） in cells were detected by Western blot. ResultsThe GSE76862 and GSE22490 datasets were obtained from the GEO database. Differential gene analyses showed that the KEAP1， Nrf2， and FoxO3 genes were all associated with the disease. After matching with the oxidative stress pathway， nine significantly differential pathways were identified （P<0.05）， among which three contained the target genes Nrf2 and FoxO3. A total of 246 active ingredient targets of TSPSP and 2 804 SA-related targets were obtained through network pharmacology， and 154 potential action targets were obtained after taking the intersection. Topological analysis showed that targets such as KEAP1 and Nrf2 exhibited high degree values. GO and KEGG enrichment analyses indicated that the intersection targets were mainly involved in oxidative stress response， FOXO and MAPK signaling pathways， etc. In in vitro experiments， compared with the blank group， the cell viability in the model group was significantly decreased （P<0.01）. Compared with the model group， the cell viability in each TSPSP-containing serum group was significantly increased （P<0.01）. Compared with the 10% TSPSP-containing serum group， the cell viability in the ML385 group decreased to approximately 70% （P<0.01）. Compared with the blank group， the model group showed significantly increased contents of MDA， Fe²⁺， and ROS， decreased GSH expression （P<0.01）， significantly reduced cell migration rate （P<0.01）， and increased protein and mRNA expression levels of KEAP1 and FoxO3 （P<0.01）， while decreased protein and mRNA expression levels of Nrf2， GPX4， and SOD （P<0.01）. Compared with the model group， each TSPSP-containing serum group showed significantly decreased contents of MDA， Fe²⁺， and ROS， increased GSH expression （P<0.01）， significantly increased migration rate （P<0.01）， significantly decreased protein and mRNA expression levels of KEAP1 and FoxO3 （P<0.05， P<0.01）， and significantly increased protein and mRNA expression levels of Nrf2， GPX4， and SOD （P<0.05， P<0.01）. Compared with the 10% TSPSP-containing serum group， the ML385 group showed reversed trends in all indicators （P<0.05， P<0.01）. ConclusionTSPSP can inhibit H₂O₂-induced oxidative stress injury of trophoblast cells， and its mechanism of action may be related to the drug activating the KEAP1/Nrf2/FoxO3 signaling pathway.
