Background: Visual impairment is increasingly prevalent, underscoring the need for effective prevention strategies. This study investigated the association between cardiovascular health and visual impairment using three progressively developed metrics: Life’s Simple 7 (LS7), a cardiovascular health score developed by the American Heart Association based on 7 components, including physical activity, smoking status, body mass index (BMI), diet, blood glucose, blood pressure, and total cholesterol; Life’s Essential 8(LE8), which adds sleep health as an additional component; and Life’s Crucial 9 (LC9), which further incorporates mental health. We aimed to evaluate whether these expanded metrics provide additional explanatory value and to inform future public health strategies. Objective: To investigate the associations among LS7, LE8, and LC9 cardiovascular health scores and visual impairment in National Health and Nutrition Examination Survey 2013 to 2018, assess the added value of sleep and mental health components, and identify key contributing subcomponents using regression and machine learning methods. Methods: We analyzed data from 9891 participants in the 2013 to 2018 National Health and Nutrition Examination Survey. Multivariable logistic regression, restricted cubic spline modeling, and subgroup analyses were conducted to evaluate the association between cardiovascular health and visual impairment. Machine learning methods, including Random Forest and SHapley Additive exPlanations, a model interpretation approach used to assess feature importance, were applied. The Boruta algorithm, a feature selection method, was used to identify key subcomponents of cardiovascular health. Results: Participants with visual impairment were older, had lower poverty-to-income ratios, and exhibited lower cardiovascular health scores (LS7, LE8, and LC9). Higher cardiovascular health scores were negatively associated with visual impairment. Each one standard deviation increase in LS7, LE8, and LC9 was associated with approximately 8%, 2%, and 3% lower odds of visual impairment, respectively. LS7 showed the strongest negative association, whereas LE8 and LC9 emerged as the most important predictors in the machine learning models. Key subcomponents such as blood glucose, blood pressure, and BMI, as well as mental health status, were strongly associated with visual impairment. Conclusion: Higher cardiovascular health scores were negatively associated with visual impairment. LS7 demonstrated the strongest statistical association, whereas LE8 and LC9 were the most influential features in the machine learning models. Blood glucose, blood pressure, BMI, and mental health status were important correlates of visual impairment. From the perspective of the “prevention and treatment of diseases” in traditional Chinese medicine and the holistic concept, the aforementioned research findings confirm that severe visual impairment is indeed an external manifestation of overall health imbalance (such as organ dysfunction and Qi deficiency and blood stasis). The prevention strategy lies in comprehensively adjusting lifestyle, emotional factors, and metabolic indicators (corresponding to the key factors in the study) to restore the body’s internal balance and achieve prevention before disease arises.

This paper summarizes Professor Gao Jiansheng's clinical experience in treating herpes simplex keratitis （HSK） based on the theory of hidden pathogens. It is believed that the core pathogenesis of HSK involves deficiency of vital qi and the internal presence of pathogenic factors. In the early stage， the pathogenesis is characterized by lung and spleen qi deficiency and invasion of external pathogens. In the middle stage， pathogenesis worsens due to latent pathogens damaging the vital qi and spleen deficiency with dampness. In the late stage， kidney yang deficiency and lingering pathogenic toxins are the root cause of recurrent attacks. In clinical practice， it is recommended to strengthen and protect the vital qi. In the early stage， the Modified Yupingfeng Powder （玉屏风散） is used. In the middle stage， the Modified Linggui Zhugan Decoction （苓桂术甘汤） is used. In the late stage， a self-formulated Modified Bushen Tuodu Fomulation （补肾托毒方） is applied. Additionally， herbs of tonifying qi and strengthening the exterior are used throughout the treatment to reduce recurrence.

Objective:To investigate the influencing factors of adult dental fluorosis in drinking water-borne endemic fluorosis areas of Inner Mongolia Autonomous Region.Methods:A case-control study was conducted in January 2024 to select adult fluorosis patients (case group) and healthy individuals (control group) from the drinking water-borne endemic fluorosis areas in Helinger County, Hohhot City, Inner Mongolia Autonomous Region as the survey subjects. Urine samples were collected to determine urinary fluoride concentration. A questionnaire survey was conducted. SPSS 25.0 software was used for χ 2 test and multivariate logistic regression analysis. Restricted cubic spline (RCS) was used to analyze the association between urinary fluoride concentration and the risk of dental fluorosis in adults. Results:A total of 161 individuals were included in the survey, including 100 in the case group and 61 in the control group. The results of univariate analysis showed that there were statistically significant differences in the distribution of gender, smoking, and urinary fluoride concentration between the case group and the control group (χ 2 = 7.54, 5.02, 9.69, P < 0.05). The results of multivariate logistic regression analysis indicated that gender ( OR = 0.36, 95% CI: 0.18 - 0.73, P = 0.005) and urinary fluoride concentration ( OR = 3.08, 95% CI: 1.46 - 6.67, P = 0.003) were the influencing factors of adult fluorosis. RCS analysis showed a significant linear dose-response relationship between the risk of dental fluorosis and urinary fluoride concentration ( Poverall trend = 0.001, Pnonlinear = 0.071). When the urinary fluoride concentration was greater than 1.57 mg/L, the risk of dental fluorosis increased with the increase of urinary fluoride concentration. Conclusion:Gender and urinary fluoride concentration are the risk factors of dental fluorosis in adults in drinking water-borne endemic fluorosis areas of Inner Mongolia Autonomous Region.

Metastatic dissemination is the major cause of death from breast-cancer (BC). Fusobacterium nucleatum (F.n) is widely enriched in BC and has recently been identified as one of the high-risk factors for promoting BC metastasis. Here, with an experimental model, we demonstrated that intratumoral F.n induced BC aggressiveness by transcriptionally activating Epithelial-mesenchymal transition-associated genes. Therefore, the F.n may be a potential target to prevent metastasis. Given the fact that cancer-associated fibroblasts (CAFs) are abundant in BC and located near blood vessels, we report an optogenetic system that drives CAF to in situ produce human antibacterial peptide LL37, with the characteristics of biosafety and freely intercellular trafficking, for depleting intratumoral F.n, leading to a 72.1% reduction in lung metastatic nodules number without affecting the balance of the systemic flora. Notably, mild photothermal treatment was found that could normalize CAF, contributing to synergistically inhibiting BC metastasis. In addition, the system can also simultaneously encode a gene of TNF-related apoptosis-inducing ligand to suppress the primary tumor. Together, our study highlights the potential of local elimination of tumor pathogenic bacteria to prevent BC metastasis.

Objective:To construct a multimodal induction educational system suitable for standardized pediatric residency training bases, and to evaluate its effectiveness, thereby obtaining suggestions for further improvement.Methods:Twelve residents newly enrolled in the 2023 standardized residency training program who commenced their first-year training were included as study subjects. The induction educational system comprised multiple modules: department introduction, training plan and assessment requirements, departmental workflow, routine diagnosis and treatment of major diseases, specialized skills/procedures, and lifestyle guidance. Training materials and methods were tailored to the characteristics of each training module. Checklists were used for supervision and review, and a competency checklist was designed to evaluate residents' mastery of the training at two weeks of induction, which would guarantee the effectiveness of the training. A questionnaire survey, powered by wjx.cn, was used to obtain the experience and suggestions from the residents and ward instructors on induction education, and content ranking analysis was performed on the survey results.Results:The survey revealed that, before starting a new rotation, residents' top three educational needs were departmental workflow, routine diagnosis and treatment of common diseases, and specialized skills/procedures. Residents preferred face-to-face lectures and demonstrations by attending physicians or senior residents; instructors suggested improving relevant materials (such as resident physician manuals and video materials) and face-to-face lectures. The residents considered the current induction educational system to be greatly beneficial in basic theories, treatment principles, basic skills, and auxiliary examination processes.Conclusions:Through the above research, a multimodal induction educational system suitable for the standardized pediatric residency training base in the Peking University First Hospital has been preliminarily established, and suggestions for further improvement have been obtained, which is conducive to further improving the system and residents' post competency.

Objective:To study the relationship between the levels of multiple elements in urine and the risk of arsenic poisoning in populations exposed to drinking water arsenic in Inner Mongolia Autonomous Region (Inner Mongolia).Methods:From April 2023 to January 2024, a case-control study method was used to select 128 individuals with a residence time of ≥10 years in drinking water arsenic exposed areas in Inner Mongolia as study subjects. Eighty-one individuals diagnosed with arsenic poisoning were selected as the case group, and 47 healthy individuals were selected as the control group for urine sample collection and questionnaire survey. Inductively coupled plasma mass spectrometry was employed to determine the levels of 10 elements (chromium, manganese, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium and lead) in urine. The levels of each element in urine were divided into four groups ( Q1, Q2, Q3, and Q4 groups) based on quartiles. The associations between the levels of various elements in urine and the risk of arsenic poisoning were studied using binary logistic regression model and restricted cubic spline (RCS). Results:The age of the control group and the case group [ M ( Q1, Q3)] were 61 (53, 69) and 61 (56, 67) years old, respectively. There were 19 and 43 males, and 28 and 38 females, respectively. There was no statistically significant differences in age and and gender composition between the two groups ( Z = - 0.39, P = 0.700; χ 2 = 1.91, P = 0.167). The levels of urinary copper and cadmium of the case group were higher than those of the control group, and the differences were statistically significant ( Z = - 2.66, - 2.16, P < 0.05). The results of univariate logistic regression analysis showed that urinary copper was an influencing factor for arsenic poisoning ( P = 0.017). The results of multivariate logistic regression analysis revealed that after adjusting for covariates, urinary copper and arsenic were independent influencing factors of arsenic poisoning ( P < 0.05). Taking Q1 group as a reference, urinary copper in Q3 group [ OR (95% CI) = 8.23 (1.81, 37.39), P = 0.006] increased the risk of arsenic poisoning, while urinary arsenic in Q2, Q3, and Q4 groups [ OR (95% CI) = 0.24 (0.06, 0.92), 0.12 (0.03, 0.53), 0.15 (0.04, 0.63), P < 0.05] decreased the risk of arsenic poisoning. After adjusting for covariates, RCS did not show a dose-response relationship between urinary copper, urinary arsenic, and arsenic poisoning ( P > 0.05). Conclusion:Urinary arsenic and copper are associated with the risk of arsenic poisoning in the drinking water arsenic exposed areas of Inner Mongolia, copper exposure may contribute significantly to arsenic poisoning.

Objective:To construct an indicator system for entrustable professional activities (EPAs) in the general practice enhancement stage of pediatric specialist physician training.Methods:A draft indicator system for EPAs in the general practice enhancement stage of pediatric physician training was developed through core EPAs working group discussion, literature review, nominal group discussion, and expert consultation. Subsequently, the indicator system was preliminarily implemented and revised.Results:The core EPAs working group consisted of nine specialist physician trainers. In the initial brainstorming stage, a "potential list" of 30 activities was established. After literature review and collation, the draft indicator system included eight EPAs. Through nominal group discussion, the connotation of the draft was enriched, and the importance of the EPAs was ranked and modified. Finally, through expert consultation, the EPAs for the general practice enhancement stage of pediatric specialist physician training were determined. These included basic operations for the treatment of critically ill children, identification and management of critical illnesses, referral of critically ill children, perioperative management, in-hospital consultation, medical and teaching management and system improvement, doctor-patient communication and dispute handling, and response to public health events. During the preliminary implementation stage, a total of nine specialist physicians who participated in the training were evaluated. Based on the problems found in the pre-evaluation, the indicators of EPAs were revised, and a corresponding curriculum training system was developed.Conclusions:Through multiple rounds of nominal group discussion and expert consultation, the indicator system for EPAs in the general practice enhancement stage of pediatric specialist physician training was formulated. The system was preliminarily implemented and revised, and a curriculum system was constructed.

Objective:To investigate the correlations among diabetes-related distress, self-management behavior, empowerment, and glycated hemoglobin (HbA1c) levels in patients with type 2 diabetes mellitus (T2DM) .Methods:A convenience sampling method was used to recruit a total of 1 927 hospitalized patients with T2DM from the Endocrinology Departments of five tertiary general hospitals in Hainan, Jiangsu, and Henan Provinces between December 2022 and December 2023. General demographic and clinical data were collected. The Problem Areas in Diabetes 5 (PAID-5), the Summary of Diabetes Self Care Activities (SDSCA), and the Diabetes Empowerment Scale-Short Form (DES-SF) were used to evaluate patients' psychological distress, self-management behaviors, and empowerment levels. Pearson correlation analysis was performed to examine the relationships among diabetes-related distress, empowerment, self-management behaviors, and HbA1c levels.Results:Pearson correlation analysis showed that diabetes-related distress was negatively correlated with empowerment ( r=-0.119, P<0.001) and the total score of self-management behavior ( r=-0.106, P<0.001), and positively correlated with HbA1c levels ( r=0.103, P<0.001). Empowerment was positively correlated with self-management behavior ( r=0.538, P<0.001) and negatively correlated with HbA1c levels ( r=-0.170, P<0.001). Self-management behavior was negatively correlated with HbA1c levels ( r=-0.165, P<0.001) . Conclusions:Diabetes-related distress, empowerment, and self-management behavior are all associated with glycemic control. Future research and interventions should focus on enhancing patients' self-management abilities, strengthening empowerment, and providing psychological support in order to improve glycemic outcomes and offer a more comprehensive and effective management approach for patients with T2DM.

Benign essential blepharospasm(BEB)is a neurological disorder characterized by involuntary contractions of periocular muscles, which can lead to functional blindness and significantly impair patients' quality of life. This article systematically reviews the epidemiology, clinical manifestations, pathogenesis, and therapeutic advances in BEB. Epidemiological data indicate that the global prevalence of BEB is approximately 1 in 200000, with a predilection for individuals over 50 years of age and a significantly higher incidence in female than in male. The exact pathogenesis of BEB remains incompletely understood, though current evidence suggests close associations with neurotransmitter dysfunction, reduced cortical inhibition, and genetic susceptibility. Therapeutic strategies primarily focus on symptomatic management. Botulinum toxin type A(BTX-A)injection remains the first-line treatment but requires repeated administrations due to transient efficacy. Other treatments, including oral drugs, surgery, and repetitive transcranial magnetic stimulation, also have major limitations. By synthesizing recent research progress from domestic and international studies, this review aims to provide novel insights for the clinical management of BEB, ultimately improving patient outcomes.
