ObjectiveTo analyze the epidemiological characteristics of latent tuberculosis infection (LTBI) among newly detained populations in eastern China, to identify high-risk groups, and to provide a scientific basis for formulating tuberculosis prevention and control strategies in the prison system. MethodsA cross-sectional study was conducted among the newly admitted detainees in two prisons in eastern China in 2022. Data on demographic characteristics, behavioral risk factors and previous disease history of the research subjects were collected through a structured questionnaire survey. The LTBI status of the detainees was determined using the QuantiFERON-TB Gold In-Tube (QFT-GIT) method. Lasso regression was used to screen variables, followed by multivariate logistic regression analysis to investigate the influencing factors of LTBI. ResultsA total of 305 detainees were included in the study. The median age of detainees was 35 (31, 43) years. The study population was predominantly male (67.21%), of Han ethnicity (95.41%), had a junior or senior high school education (59.34%), and was unemployed (31.80%). A history of smoking was reported by 52.79% of participants, while 57.70% reported no alcohol consumption. The majority had no history of hypertension (85.90%), diabetes mellitus (93.77%), human immunodeficiency virus (HIV) infection (97.38%), familial genetic diseases (95.08%), surgery or trauma (73.77%), drug use (92.79%), or hepatitis (93.77%). The LTBI rate was 14.75%. After comparing the demographic characteristics of LTBI and non-infected groups, it was found that smoking history (χ²=7.40, P=0.025), drug use history (χ²=5.49, P=0.019), and HIV infection (χ²=8.12, P=0.004) were statistically correlated with LTBI infection. The results of multivariate logistic regression analyses showed that smoking [adjusted odds ratio (aOR)=4.08, 95%CI: 1.60‒10.42, P=0.003], HIV infection (aOR=11.57, 95%CI: 2.50‒53.51, P=0.002) and drug use (aOR=3.04, 95%CI: 1.02‒9.09, P=0.046) were risk factors for LTBI. ConclusionThe LTBI rate among newly detainees in two prisons in eastern China is slightly lower than that among long-term detainees. Early screening and intervention should be implemented for newly detainees, with particular attention focused on high-risk groups such as those with a history of smoking, HIV infection, or drug use.

With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Objective To evaluate the efficacy and safety of a combination therapy regimen comprising stereotactic body radiation therapy (SBRT) combined with liposomal irinotecan, camrelizumab, and anti-angiogenic therapy (CAP) in patients with advanced bone and soft tissue sarcomas. Methods This study is a prospective subgroup analysis of the multicenter, open-label, single-arm phase Ⅱ CAP trial (NCT04569916), which enrolled 60 patients with advanced solid tumors who had progressed after standard therapy between November 2020 and February 2023, including 11 patients with advanced bone and soft tissue sarcomas. All patients received sequential liposomal irinotecan within 48 hours after stereotactic body radiotherapy (SBRT), followed by maintenance therapy with camrelizumab and an anti-angiogenic agent until disease progression or intolerable toxicity. The primary efficacy endpoint was objective response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results In the bone and soft tissue sarcoma subgroup (n=11), three patients achieved partial response (PR), five had stable disease (SD), and three experienced disease progression (PD). ORR was 27.3%, and DCR was 72.7%. mPFS was 5.8 months (95%CI: 2.2-10.3), and mOS not reached. Regarding safety, adverse reactions primarily included bone marrow suppression, fatigue, and gastrointestinal reactions, indicating overall manageable toxicity. Conclusion As a subgroup analysis of the CAP study, this research suggests that radiotherapy combined with liposomal irinotecan, camrelizumab, and anti-angiogenic therapy demonstrates certain efficacy in advanced bone and soft tissue sarcomas that have failed multiple lines of treatment, with overall manageable adverse reactions. Future studies should expand the sample size.

Objective: To analyze near work illuminance patterns on school days and weekends among third and fourth grade primary school students by using objectively monitored data, and to examine the associations of the duration of near work under different illuminance levels and time weighted average near work illuminance with screening myopia. Methods: From April to June 2024, students from grades 3 and 4 in two primary schools in Jiading District, Shanghai were selected as study subjects by using stratified random cluster sampling method. Continuous objective monitoring of near work behavior was conducted for 7 days while information from uncorrected visual acuity and refractive assessment was collected, and an online questionnaire survey was administered to their parents. Valid samples comprised 372 students on school days and 292 on weekends. Welch s t test was used to compare differences in the duration of near work under different illuminance levels between the screening myopia and non-myopia groups. Multivariable binary Logistic regression analysis was employed to assess the association between the duration of near work under different illuminance levels and screening myopia. Restricted cubic spline (RCS) model was used to explore the nonlinear association between time weighted average near work illuminance with 60 cm and screening myopia, and the critical thresholds identified by the RCS model were used to categorize illuminance levels for subsequent Logistic regression analyses. Results: Objective monitoring of near work behavior showed that the duration of near work in the low illuminance range of [0,125)lx was significantly longer on weekends[(4.12±2.21)h] than on school days [(2.42±1.22)h]. Multivariate Logistic regression analysis revealed that only on school days, each additional hour of near work duration in the [0,125)lx ( OR =1.56, 95% CI =1.23-1.98) and ≥1 000 lx range ( OR =5.92, 95% CI =1.48-23.73) were significantly associated with higher odds of screening myopia(both P < 0.05). RCS plot showed that on school days, time weighted average near work illuminance with 60 cm had a non-linear association with screening myopia ( P non-linear <0.05). On weekends, no significant association was found between near work illuminance indicators and screening myopia (all P >0.05). Conclusions Primary school students engage in near work for considerable durations in insufficient lighting environments on both school days and weekends. Increased duration of near work in overly dim or bright environments on school days may increase the risk of screening myopia.

Objective On the basis of the theory of the tumor metastatic state, this work aims to explore the metastasis trajectories and peripheral immune response patterns in patients with non-small cell lung cancer (NSCLC) receiving vital qi-strengthening and toxin-eliminating therapy (Fuzheng Juandu) and reveal the value of peripheral immunity in assessing vital qi deficiency during metastasis. Methods A retrospective study design was adopted. Patients with NSCLC admitted from January 1, 2018, to October 31, 2025 were enrolled. Data on metastasis status and peripheral immune indices were collected at the follow-up time points of one, two, three, and five years. Group-based trajectory modeling was used to fit metastasis trajectories, and the independent predictors of trajectory grouping were analyzed through multifactor and multiclassification logistic regression. Results A total of 184 patients with NSCLC were included, and three different groups of metastasis trajectories were identified, namely, the low-risk stable (46.74%, n=86), low-risk rising (13.59%, n=25), and high-risk stable (39.67%, n=73) groups. Univariate analysis revealed substantial differences in peripheral immune indices among the three trajectory groups. Multivariate analysis showed that TNM stage, absolute neutrophil count, lymphocyte count, absolute monocyte count, platelet volume, SAA:CRP ratio, and NLR were independent predictors of the low-risk rising group, whereas TNM stage, absolute monocyte count, basophil count, SII, and NLR were independent predictors of the high-risk stable group. Conclusion Under Fuzheng Juandu therapy, patients with NSCLC exhibit three distinct metastasis trajectories, each corresponding to a specific peripheral immune response pattern. Elucidating these peripheral immune response patterns may facilitate the objective quantification of the degree of vital qi deficiency, prediction of future metastasis risk, and providing an important reference for the individualized clinical implementation of Fuzheng Juandu therapy.

OBJECTIVE To evaluate the cost-effectiveness of brivaracetam （BRV） versus perampanel （PER） as add-on therapy for drug-resistant focal epilepsy in adults from the perspective of the Chinese healthcare system.METHODS A Markov model was established to simulate the progression of drug-resistant focal epilepsy in adults， with a simulation cycle of 5 months， a time horizon of 44 years， and a discount rate of 4.5%. Clinical data required for the model were derived from the phase Ⅲ clinical trial of BRV and a post hoc analysis of PER； cost data and utility data were obtained from Yaozh and related literature. The willingness-to-pay （WTP） threshold was set at twice China’s 2025 per capita gross domestic product （GDP） [199 330 yuan per quality-adjusted life year （QALY）]， and a cost-effectiveness analysis was adopted to compare the cost-effectiveness of the regimens. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to confirm the stability of the base-case analysis conclusions.RESULTS The incremental cost-effectiveness ratio （ICER） of BRV 50 mg/d as an add-on therapy versus PER 8 mg/d was 44 823.08 yuan/QALY， which was below the WTP threshold； the ICER of BRV 200 mg/d versus PER 12 mg/d was 238 783.00 yuan/QALY， which was above the WTP threshold. In the one-way sensitivity analysis， the direct medical cost of seizures ≥53 times/year and the health utility value of a seizure-free state per year had a relatively large impact on the two ICER results mentioned above， respectively. Probabilistic sensitivity analysis indicated that the above results were robust.CONCLUSIONS For the selection of add-on therapy for drug-resistant focal epilepsy in adults in China， when twice China’s per capita GDP is used as the WTP threshold， BRV 50 mg/d has a cost-effectiveness advantage over PER 8 mg/d， whereas BRV 200 mg/d not have a cost-effectiveness advantage over PER 12 mg/d.

Based on the theory of "combined bi （痹） syndrome of the body and zang （脏）organs"， this paper elucidates the pathogenic transmission and treatment principles of systemic sclerosis-associated interstitial lung disease （SSc-ILD）. For the pattern in which the disease transmits from the body to the zang organs， the underlying pathogenesis is blood deficiency and liver constraint with cold congealing in the collaterals. The treatment principle is to nourish the blood and warm the channels， diffuse the lung and defend against pathogenic factors， so as to interrupt the inward transmission of the disease. For the pattern in which the disease transmits from the zang organs to the body， the pathogenesis may involve lung deficiency with insecurity of the exterior， liver fire attacking the lung and scorching the collaterals， or latent pathogens of phlegm and blood stasis permeating outward. The treatment principle is to tonify the lung and secure the exterior， clear the liver and purge the lung， and resolve blood stasis and unblock the collaterals， so that when the zang organs are restored， the body can be nourished. For the pattern in which the body and zang organs are simultaneously affected， the pathogenesis lies in violent toxin pathogens spreading throughout the three jiao （焦） and damaging both the body and zang organs. The treatment principle is to cool the blood and resolve toxins， resolve blood stasis and unblock the collaterals， thereby eliminating pathogenic factors from both the interior and exterior. Emphasis is placed on simultaneous treatment of the body and zang organs and dynamic syndrome differentiation and treatment， providing a new approach to understanding the pathogenesis of SSc-ILD in traditional Chinese medicine and to its stratified treatment.

Objective To explore the current situation of medication safety behavior of elderly cancer patients and the path relationship of various influencing factors for improving medication safety behavior.Methods A total of 340 elderly cancer patients were investigated by a demographic questionnaire,the Medication Safety Behavior Scale,the Medication Literacy Scale,the Family Care Index Questionnaire,and the Chinese version of the Empowerment Scale for Cancer Patients from August to December 2024.The multiple linear regression analysis was applied to analyze influencing factors,and data were analyzed using SmartPLS 4.0 to construct a partial least squares structural equation model with path analysis.Results A total of 307 valid questionnaires were collected.The mean medication safety behavior score was 31.89±5.38.Residential area,drug literacy,family care,and health empowerment are factors that affect medication safety in elderly cancer patients,accounting for 37.3％of the total variation.The path analysis results indicated that health empowerment(β=0.480),medication literacy(β=0.154),and family care(β=0.227)positively correlate with medication safety behavior.Health empowerment played a partial mediating role between family care and medication safety behavior,as well as between medication literacy and medication safety behavior.The mediating effects are 0.125 and 0.332(P＜0.001),accounting for 35.51％and 68.31％of the total effect,respectively.Conclusion Medication safety behaviors among elderly cancer patients are at a median level and influenced by multiple factors.By improving their levels of health empowerment,healthcare professionals can motivate patients to take an active role in medication safety management.Further,promoting education on medication knowledge and teaching relevant medical skills,and together with guiding patients to perceive family care and support,can collectively improve their overall medication safety behaviors.

Objective:To analyze the effects of fluorine exposure on calcium ion metabolism and the expression of related calcium-regulating proteins in the kidneys of rats.Methods:Forty-five 5-week-old specific pathogen-free male Wistar rats (weighed 90 - 120 g) were selected and divided into three groups according to the randomized numeric table: 0 (control), 50, and 100 mg/L fluorine exposure groups, with 15 rats in each group. The control group was given deionized water, while the 50 and 100 mg/L fluorine exposure groups were given sodium fluoride solutions containing 50 and 100 mg/L fluorine ions, respectively. After 12 weeks, urine samples were collected, and kidneys and blood were harvested. Urinary fluorine levels were measured using a fluoride ion-selective electrode method. Calcium ion levels in the urine, kidneys, and serum were determinated using the methylthymol blue microplate method. The protein expression levels of transient receptor potential vanilloid receptor 5 (TRPV5), calbindin-D28K (CB-D28K), sodium-calcium exchanger-1 (NCX1), Klotho and plasma membrane calcium ATPase 1b (PMCA1b) in the kidneys were detected by Western blotting and immunohistochemistry.Results:The urinary fluorine levels in the control group and the 50 and 100 mg/L fluorine exposure groups were (0.48 ± 0.09), (20.01 ± 1.68), (37.45 ± 2.45) mg/L, respectively, with statistically significant differences between the groups ( F = 929.58, P < 0.001). Significant differences in calcium ion levels in urine, kidneys, and serum were observed among the three groups ( F = 14.66, 11.09, 10.31, P < 0.05). Compared with the control group, the 100 mg/L fluorine exposure group exhibited higher levels of calcium ion in the urine and kidneys, and lower serum calcium ion levels ( P < 0.05). The results of Western blotting analysis revealed that the protein expression levels of TRPV5 and CB-D28K in the kidneys increased with the increase of fluorine exposure level ( Z = 2.11, 2.11, P = 0.035). The protein expression level of NCX1 in the kidneys showed a decreasing trend with increasing fluorine exposure level ( Z = - 2.11, P = 0.035). Significant differences were also observed in the protein expression levels of Klotho and PMCA1b among the three groups ( F = 8.93, 7.08, P < 0.05). Compared with the control group, the 100 mg/L fluorine exposure group showed higher level of Klotho protein expression and lower level of PMCA1b protein expression in the kidneys ( P < 0.05). Immunohistochemical results indicated significant differences in the protein expression levels of TRPV5, CB-D28K, NCX1, and Klotho in the kidneys of the three groups ( F = 27.56, 24.94, 16.05, 32.72, P < 0.05). Compared with the control group, the protein expression levels of TRPV5, CB-D28K, and Klotho in kidneys of 50 and 100 mg/L fluorine exposure groups were higher, while the protein expression levels of NCX1 were lower ( P < 0.05). Conclusion:Fluorine exposure may cause calcium ion metabolism disorders by regulating the expression levels of Klotho and other calcium-regulating proteins in the kidneys.

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.
