This study aims to describe the population and regional distribution characteristics of smoking behavior among adult twins in the China Twin Registry (CNTR), as well as the concordance rates for smoking behavior in monozygotic and dizygotic twins, and estimate the heritability. The study population included adult twins in CNTR who had smoking questionnaire data. A random-effects regression model was used to describe the distribution of smoking behavior among different subgroups based on various characteristics. The concordance of smoking behavior between different zygosity groups was calculated, and heritability was estimated. A total of 28 444 twin pairs were included in this study, with an average age of (36.6±12.0) years. Among male twins, 41.2% were current smokers, while only 1.2% of females smoked. Higher smoking rates were observed among male smokers in the 50-59 age group ( z=23.0, P<0.001), northern regions ( z=2.9, P<0.01), rural areas ( z=-5.2, P<0.001), those who were divorced/widowed ( z=3.8, P<0.001), and first-born twins ( z=-4.3, P<0.001), while lower smoking rates were found in those with higher education ( z=-16.1, P<0.001) and unmarried individuals ( z=-16.0, P<0.001). The smoking concordance rate for male monozygotic twins was 69.6%, significantly higher than the 57.3% concordance rate for dizygotic twins ( χ 2=105.0, P<0.05). The heritability of smoking behavior in male twins was estimated at 28.9% (95% CI: 24.3%-33.4%). Stratified analyses showed differences in heritability across regions and age groups: the heritability in northern regions was 32.6% (95% CI: 27.3%-38.0%), higher than the 21.0% (95% CI: 12.4%-29.5%) observed in southern regions; the highest heritability of 35.1% (95% CI: 26.3%-43.9%) was found in the 18-29 age group, with heritability decreasing with age. In conclusion, the smoking rate and influencing factors in the twin population are similar to those in the general population, with unique characteristics, such as higher smoking rates in first-born twins. Genetic factors have a significant impact on smoking behavior.

Background and purpose:Melanoma is a highly invasive malignant tumor originating from melanocytes,which poses a great threat to human life and health around the world,and its morbidity and mortality have been rising continuously in recent years.Telomerase and autophagy play crucial roles in cell proliferation,survival and stress response.Telomerase maintains the replication ability of cells by prolonging telomeres at the ends of chromosomes,and autophagy,as a self-degradation mechanism of cells,can not only help cells remove damaged components to promote survival,but also induce cell death under certain conditions.In the tumor environment,they are often abnormally activated or out of balance,and participate in the occurrence and development of many cancers,including melanoma.This study investigated the roles of telomerase and autophagy in melanoma progression and evaluated the potential synergistic therapeutic effects of combined application of telomerase inhibitor BIBR1532 and autophagy inhibitor chloroquine(CQ)in melanoma treatment.Methods:Malignant melanoma cells A375 were treated with telomerase inhibitor BIBR1532.The cell viability was assessed using the cell counting kit-8(CCK-8)assay,and the cell apoptosis was detected using the Annexin Ⅴ/propidium iodide(PI)double staining method.Additionally,the expressions of autophagy-related proteins LC3-Ⅱand p62 were detected by Western blot,and the changes in autophagy flux were observed using dual-tagged adenovirus transfection technology.Based on these studies,BIBR1532 and the autophagy inhibitor CQ were further applied in combination to analyze cell proliferation,apoptotic rate,changes in mitochondrial membrane potential,and cell cycle distribution,and the cloning formation experiment was used to verify the cell's proliferative capacity,thereby comprehensively evaluating the efficacy of this combined treatment strategy.Results:Telomerase inhibitor BIBR1532 at a concentration of 50 μmol/L significantly inhibited the growth of malignant melanoma cells A375 and induced apoptosis.At the same concentration,BIBR1532 upregulated the expression of the autophagy-related protein LC3-Ⅱ in A375 cells,while downregulating the expression of p62 protein.By transducing A375 cells with a dual-tagged adenovirus,it was observed that autophagy flux was significantly enhanced after treatment with BIBR1532.Furthermore,the combined application of BIBR1532(50 μmol/L)and the autophagy inhibitor CQ(20 μmol/L)significantly promoted the death of A375 cells,induced apoptosis and destruction of mitochondrial membrane potential,caused cell cycle arrest at the G2/M phase,and significantly inhibited the cell's clonogenic ability.Conclusion:Telomerase inhibitor BIBR1532 not only inhibits the proliferation of malignant melanoma cells but also activates the autophagy process in these cells,and inhibition of the autophagy response by autophagy inhibitor CQ can enhance the sensitivity of malignant melanoma cells to telomerase inhibitor BIBR1532.

The adverse effects of fine particulate matter (PM 2.5) on human health have become a major global public health concern. Pregnant women and fetuses, as susceptible populations, are more vulnerable to the threat of PM 2.5 pollution. Increasing studies indicate that PM 2.5 exposure is an important risk factor of fetal growth restriction (FGR), and oxidative stress, inflammatory response, endocrine disorders, epigenetic modifications, autophagic abnormalities, and gut microbiota dysbiosis may be the biological mechanisms underlying PM 2.5-induced FGR. This study offers insights for the development of targeted preventive and therapeutic methods for FGR caused by PM 2.5.

Objective:To investigate the diagnostic and surgical strategies in managing patients with coexisting thyroid carcinoma and cervical vagal schwannoma.Methods:We retrospectively analyzed three cases treated at Guangzhou First People’s Hospital between Jun. 2019 and Dec. 2024.Results:All patients presented with neck masses or thyroid nodules. Ultrasonography identified suspicious malignant thyroid nodules and lateral neck lesions—interpreted as metastatic lymphadenopathy in two cases and as a possible nerve sheath tumor in one. Fine-needle aspiration cytology (FNAC) of thyroid nodules yielded Bethesda VI results in all cases. FNAC of the lateral neck lesions revealed no evidence of malignancy in all cases; in one case, a core needle biopsy confirmed a vagal schwannoma. Two patients underwent MRI, which supported the diagnosis of vagal schwannoma. Surgical management included single-stage resection in two patients and staged surgery in one. Postoperative histopathology confirmed papillary thyroid carcinoma and schwannoma in all cases. Transient postoperative hoarseness occurred in two patients, with recovery within 3-6 months.Conclusions:When thyroid carcinoma is complicated by cervical vagal schwannoma, the schwannoma may be misdiagnosed as metastatic cervical lymph nodes, potentially leading to iatrogenic vagus nerve injury during neck dissection. Although cervical vagal schwannoma can be diagnosed preoperatively, simultaneous surgical treatment of both conditions may increase the risk of vocal cord paralysis, and in severe cases, result in airway compromise. Therefore, comprehensive preoperative evaluation is important. It is recommended to classify cases based on the anatomical locations of the thyroid carcinoma and vagal schwannoma to guide surgical planning, and to use intraoperative nerve monitoring to enhance surgical safety and avoid serious complications.

In recent years, generative artificial intelligence (AI) technologies have achieved remarkable progress in the early screening, risk prediction, disease progression assessment, and clinical trial design of glaucoma.Using advanced algorithms, such as generative adversarial networks, variational autoencoders, and diffusion models, researchers have synthesized high-quality structural images of the optic disc, macular region, and retinal nerve fiber layer, which effectively alleviates the limitations of scarce clinical imaging data and label imbalance.These methods have substantially improved the accuracy and generalization of deep learning models in visual field defect prediction, structure-function mapping, and longitudinal disease progression simulation.Meanwhile, multimodal generative approaches that integrate imaging data, visual field tests, and clinical features have facilitated individualized prediction of glaucoma progression.In addition, large language models have shown preliminary potential in ophthalmic image interpretation, clinical text information extraction, and decision support, providing new insights into intelligent ophthalmic diagnosis and treatment.However, the clinical implementation of generative AI in glaucoma faces challenges.The pathological authenticity and cross-device consistency of generated images require further validation, which may affect the reliability of early glaucoma detection.The heterogeneous characteristics of different glaucoma subtypes, such as open-angle and angle-closure glaucoma, also limit the generalization of synthetic data.Moreover, issues related to model interpretability (" black-box" nature), artifact generation, data privacy, and ethical governance remain key barriers to clinical translation.In the future, it is expected that establishing large-scale training frameworks that incorporate multicenter, multimodal, and multiethnic datasets will enhance model robustness and clinical applicability.Furthermore, generative AI may contribute to remote ophthalmic care and personalized precision therapy by enhancing low-quality image, reconstructing missing data, and simulating dynamic disease courses.This article reviews the current applications, core technologies, and challenges of generative AI in glaucoma diagnosis and management, and discusses its future directions and translational potential in clinical ophthalmology.
