Objective: To assess the association of family food environment with dietary and nutrition literacy among junior and senior high school students, providing a basis for nutritional health education and adolescent nutritional improvement. Methods: From January 9 to February 10, 2025, a total of 1 473 junior and senior high school students aged 12-20 were recruited by using a cluster random sampling method combined with convenient sampling from 15 provinces (municipalities and autonomous regions) across China. Data on basic demographic characteristics, home food environment, and dietary and nutrition literacy were collected by using the Food and Nutritional Literacy Questionnaire for Chinese School age Children. Multiple linear regression and Logistic regression models were employed to analyze the association of the home food environment on adolescent dietary and nutrition literacy. Results: The total score of dietary and nutrition literacy among junior and senior high school students was (65.28±9.03). The score in the cognitive domain (67.59±10.56) was higher than that in the skill domain (60.74±9.15), and the score for food preparation skills (56.60±14.28) was the lowest. Students aged 16-20, senior high school students, those for only children, non boarding students, those with urban household registration, those from wealthier families, those whose primary caregivers were parents with higher education levels, and those who previously received nutrition and health education had significantly higher dietary and nutrition literacy scores compared to their respective counterpart groups ( t/F =-8.32, -8.14, 4.76, -2.70, 7.15, 18.29, 10.68, 11.66 , all P <0.05). Multiple linear regression analysis revealed that family food environment was associated with dietary and nutrition literacy, and the model was statistically significant ( R 2=0.20, F=20.54, P <0.05). Lower availability of fruits at home in the past month and lower frequency of family communication regarding dietary and nutrition were associated with lower dietary nutrition literacy scores among junior and senior high school students ( β =-1.35, -1.67, both P <0.01). Among junior and senior high school students, lower frequency of dining out with the family, watching videos during family meals, and being urged by parents to eat more food in the past month were associated with higher scores on dietary nutrition literacy ( β =1.35, 1.13, 0.71, all P <0.01). Logistic regression model results indicated that watching videos during family meals ( OR =1.70) and family communication regarding dietary and nutrition ( OR =0.51) were significantly associated with dietary and nutrition literacy levels (both P <0.05). Conclusions The score of dietary and nutrition literacy among junior and senior high school students is relatively low, and the family food environment is a key factor. It is recommended that nutrition education and improvement initiatives for junior and senior high school students prioritize attention on children and adolescents from households with less favorable food environments.

To target the pivotal BCR/ABL oncoprotein in chronic myeloid leukemia (CML) cells, tyrosine kinase inhibitors (TKIs) are utilized as landmark achievements in CML therapy. However, TKI resistance and intolerance remain principal obstacles in the treatment of CML patients. In recent years, drug repositioning provided alternative and promising perspectives apart from the classical cancer therapies, and promoted anthelmintic mebendazole (MBZ) as an effective anti-cancer drug in various cancers. Here, we investigated the role of MBZ in CML treatment including imatinib-resistant CML cells. Our results proved that MBZ inhibited the proliferation and induced apoptosis in CML cells. We found that MBZ effectively suppressed BCR/ABL kinase activity and MEK/ERK signaling pathway by reducing p-BCR/ABL and p-ERK levels with ABL1 targeting ability. Meanwhile, MBZ directly targeted the colchicine-binding site of β-tubulin protein, hampered microtubule polymerization and induced mitosis arrest and mitotic catastrophe. In addition, MBZ increased DNA damage levels and hampered the accumulation of ataxia-telangiectasia mutated and DNA-dependent protein kinase into the nucleus. This work discovered that anthelmintic MBZ exerts remarkable anticancer effects in both imatinib-sensitive and imatinib-resistant CML cells in vitro and revealed mechanisms underlying. From the perspective of drug repositioning and multi‐target therapeutic strategy, this study provides a promising option for CML treatment, especially in TKI-resistant or intolerant individuals.

Background and purpose:Accurately locating pulmonary nodules is the key to the success of thoracoscopic surgery.This study aimed to investigate the strategy and evaluate the feasibility,safety,and clinical value of thoracoscopic surgical treatment for pulmonary nodules located beneath the interlobar pleura and close to the pulmonary hilum.Methods:The patients who underwent pulmonary nodule surgery at Liaocheng Tumor Hospital from May 2023 to November 2024 were enrolled,and the patients who did not meet the inclusion criteria were excluded.This study was approved by the Ethics Committee of Liaocheng Tumor Hospital(EC-20240112-1020)and informed consent was obtained from the patients.The research was designed as a prospective single-arm study.The patients were treated with wedge resection,which was performed following CT-guided localization,where the location needle was inserted through the interlobar pleura.The feasibility of the procedure was evaluated by analyzing the success rate of preoperative localization and perioperative complications.Results:A total of 28 patients who met the inclusion criteria were included in this study.There were 5 male and 23 female patients with an average age of(56.0±8.5)years(range 38-69 years).In all,28 patients with 28 nodules underwent thoracoscopic wedge resection,and the preoperative CT-guided localization was successfully performed in all patients,without urgent complications.The mean operation time of thoracoscopic surgery was(15.6±4.0)min,intraoperative bleeding was(20.9±14.3)mL,and postoperative drainage was(214.3±62.2)mL.No cases of postoperative air leaks or conversion to thoracotomy were observed.The average length of hospital stay was(5.4±0.9)days.The postoperative histological diagnosis revealed 3 benign lesions(pulmonary fibrosis in 2 cases,atypical adenomatous hyperplasia in 1 case)and 25 malignant lesions(adenocarcinoma in situ in 5 cases,minimally invasive adenocarcinoma in 16 cases,and invasive adenocarcinoma in 4 cases).Conclusion:Thoracoscopic wedge resection following CT-guided nodule localization through the interlobar pleura is a feasible approach for nodules located beneath the interlobar pleura and close to the pulmonary hilum.The method ensures precise tumor localization,adequate margin,and minimal loss of normal lung tissue,with a low incidence of postoperative complication,which has important guiding significance for the surgical treatment of pulmonary nodules in such special locations.

Objective:To investigate the association between blood selenium levels and sex hormones in Chinese men aged 18-79 years.Methods:Data were derived from the China National Human Biomonitoring survey conducted in 2017-2018, with a final sample size of 5 414 men. General demographic characteristics, behavioral habits, and dietary frequency were collected through questionnaires and physical examinations. Fasting blood samples were collected to measure blood lead, serum testosterone, and estradiol levels. Complex sampling linear regression models were used to analyze the associations between blood selenium levels and testosterone, estradiol, and the testosterone/estradiol ratio, adjusting for confounding factors including age, education level, marital status, smoking status, alcohol consumption, seafood intake, soy product intake, protein supplement intake, BMI, and diabetes status.Results:The mean age of the 5 414 participants was (46.85±27.91) years; 4 774 (91.65%) were of Han ethnicity and 4 505 (86.68%) were married. The median ( Q1, Q3) blood selenium concentration in men was 97.80 (80.64, 116.99) μg/L. After adjusting for confounding factors, the complex sampling linear regression model revealed negative associations between blood selenium levels and both testosterone levels and the testosterone/estradiol ratio, with a significant linear trend ( Ptrend<0.05). Compared with the Q1 group, the β (95% CI) values for testosterone in the Q2, Q3, and Q4 groups were -0.02 (-0.06 to 0.02), -0.03 (-0.08 to 0.01), and -0.06 (-0.09 to -0.02), respectively. Similarly, the β (95% CI) values for the testosterone/estradiol ratio in the Q2, Q3, and Q4 groups were -0.01 (-0.03 to 0.02), -0.01 (-0.04 to 0.04), and -0.03 (-0.06 to -0.01), respectively. Subgroup analysis indicated stronger associations between blood selenium levels and testosterone/estradiol levels in non-smoking and obese men (BMI≥28 kg/m2). Conclusion:Blood selenium levels are negatively associated with testosterone levels and the testosterone/estradiol ratio in Chinese adult males.

Objective:To explore the association of blood and urinary cadmium levels with lipid profile levels and dyslipidemia in Chinese adults aged 18 to 79 years.Methods:Based on the China National Human Biomonitoring (CNHBM) program, a cross-sectional survey was conducted from 2017 to 2018 using a multi-stage stratified random sampling method, including a total of 10 713 adults aged 18 to 79 years. Data was obtained through questionnaires, physical examinations, biological sample collection, and laboratory testing. Multiple linear mixed effect model (MLMM) and generalized linear mixed effect model (GLMM) were used to analyze the association of blood and creatinine-corrected urinary cadmium levels with lipid profile levels as well as dyslipidemia among adults.Results:The age of 10 713 participants was (47.23±0.24) years, with 5 372 males accounting for 61.3% of the national population. The weighted mean±standard error (SE) of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) was (5.21±0.03), (1.86±0.03), (2.96±0.03), and (1.43±0.01) mmol/L, respectively. The prevalence rate of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, low HDL-C, and high LDL-C was 16.0%, 21.6%, 6.6%, 13.5%, and 10.0%, respectively. MLMM showed that, after adjusting for relevant confounders, log-transformed blood cadmium levels were positively associated with increased levels of TC, TG and LDL-C ( P<0.05). When blood cadmium levels were categorized into quartiles, compared to the lowest exposure group ( Q1), participants in the highest blood cadmium exposure group ( Q4) had increases of 0.19 (95% CI: 0.06, 0.32) mmol/L in TC and 0.25 (95% CI: 0.08, 0.43) mmol/L in TG. GLMM indicated that, after adjusting for confounders, higher blood cadmium exposure levels were associated with increased risks of hypercholesterolemia, hypertriglyceridemia, mixed hyperlipidemia, and high LDL-C ( P<0.05). Further analysis by quartiles showed that, compared to the blood cadmium Q1 exposure group, the OR value (95% CI) for the Q4 group was 1.53 (1.12, 2.08) for hypercholesterolemia, 1.54 (1.09, 2.17) for hypertriglyceridemia, 2.24 (1.47, 3.40) for mixed hyperlipidemia, and 1.49 (1.07, 2.09) for high LDL-C. Conclusion:The cadmium internal exposure levels are associated with blood lipid profile levels as well as the incidence of dyslipidemia in Chinese adults aged 18 to 79.

Objective To analyze the differences in the epidemiological characteristics,susceptible popula-tions,and laboratory index of patients with common acute upper respiratory tract infections(novel coronavir-us infection,influenza A and influenza B)between plateau and plain areas.Methods Clinical data of 408 008 patients with symptoms of fever or upper respiratory tract infection in the fever clinic of the Second Affiliated Hospital of Zhejiang University and General Hospital of Xizang Military Command from January 2023 to Au-gust 2024 were collected.The epidemic characteristics,susceptible populations,and peripheral blood test data were compared and analyzed.Results The total positive rate of novel coronavirus infection,influenza A virus and influenza B virus infection in plain group(17.86％)was higher than that in plateau group(14.49％),and the difference was statistically significant(P＜0.05).The positive rates(17.98％and 17.76％)of male and female upper respiratory tract infection pathogens(novel coronavirus,influenza A virus and influenza B virus)in plain group were higher than those in plateau group(13.94％and 16.00％),and the differences were statis-tically significant(P＜0.05).The total positive rates of three kinds of upper respiratory tract infection patho-gens were 16.21％,18.27％and 14.63％in the plain group,and 14.62％,14.06％and 21.26％in the plateau group,respectively.According to the results of pathogen analysis of susceptible populations,whether it was plateau or plain,the positive rate of influenza A virus was higher in the minor group,the positive rate of influ-enza B virus was highest in the adult group,and the positive rate of novel coronavirus was highest in the elder-ly group.In terms of epidemic season,plateau and plain areas were different,and the epidemic occurred earlier in the plain area.In terms of peripheral blood test indicators,there were statistically significant differences in lymphocyte count,monocyte count,neutrophil to lymphocyte ratio and other indicators between plateau group and plain group(P＜0.05),while there were no statistically significant differences in white blood cell count between plateau group and plain group(P＞0.05).Conclusion The epidemiological characteristics of acute upper respiratory tract infection in plateau area are obviously different from those in plain area,which may be related to the natural environment and human geography environment.

Objective:To investigate the immunological characteristics, particularly the alterations in peripheral blood lymphocyte subsets, including Th17 and Treg cells, cytokine dysregulation, and their clinical significance in patients with SAPHO syndrome.Methods:Fifty-three patients with SAPHO syndrome admitted to the Second Hospital of Shanxi Medical University from January 2012 to December 2023 in the department of dermatology and venereology and rheumatology with complete data were retrospectively analyzed as the study objects. At the same time, 55 healthy subjects matched by age and sex were included as healthy control group. General clinical data such as age, sex, clinical manifestations and results of laboratory tests were collected. We employed flow cytometry to assess the absolute counts of peripheral blood lymphocyte subsets and utilized cytokines detected by the flow cytometry-based multiplex protein quantification technique (CBA) to measure serum cytokine levels. We compared the differences in peripheral blood lymphocyte subsets and cytokine levels between the two groups using the rank-sum test and Spearman correlation analysis.Results:① Patients with SAPHO syndrome exhibited significantly elevated absolute counts of total B cells [240.77(180.65, 303.87)/μl vs. 165.00(132.00, 223.00)/μl, Z=-3.25, P<0.001], CD8 + T cells[504.6(381.43, 735.36)/μl vs. 429.00(357.00, 579.00)/μl, Z=-2.71, P=0.007], and CD4 + T cells 898.47(755.61, 1 019.68) vs. 637.00(544.00, 819.00), Z=-3.94, P<0.001], along with reduced NK cells[212.59(123.02, 307.72) vs. 283.00(189.00, 406.00), Z=2.95, P=0.003]. Compared with healthy controls, both Th1 [159.56(105.01, 233.09)/μl vs. 47.18(9.73, 99.12)/μl, Z=-6.52, P<0.001] and Th17 cells[17.88(12.97, 23.69)个/μl vs. 5.38(4.06, 7.42)/μl, Z=-7.11, P<0.001] and the Th17/Treg ratio[0.59(0.38, 0.84) vs. 0.17(0.13, 0.29), Z=-6.85, P<0.001] were significantly higher in the CD4 + T subset, with statistical significant difference; however, no significant differences was observed in Th2[13.09(7.98, 20.60)/μl vs. 10.22 (5.36, 15.60)/μl, Z=-1.73, P=0.084] and Treg cell [30.08(22.14, 45.16)/μl vs. 33.58(22.15, 42.13)/μl, Z=0.07, P=0.985] levels between the two groups. ② Subgroup analyses based on the presence of peripheral joint involvement and skin manifestations revealed no significant differences in lymphocyte subsets among the groups ( P>0.05). ③ No significant correlation was found between Th17, Treg cells, Th17/Treg ratio, and clinical data (ESR, CRP, skin manifestations, joint symptoms) in patients with SAPHO syndrome patients( P>0.05). ④ The serum IL-2 level in patients with SAPHO syndrome was significantly lower than in healthy controls [1.74 (1.18, 2.36)pg/ml vs. 2.73(1.76, 3.49)pg/ml, Z=4.00, P<0.001], while levels of IL-6[5.72(4.63, 7.75)pg/ml vs. 3.17(2.67, 4.06)pg/ml, Z=-7.13, P<0.001], IL-10[3.15(2.29, 4.15) pg/ml vs. 2.02(1.68, 3.13)pg/ml, Z=-0.40, P<0.001]、IL-17[8.11(4.31, 11.2)pg/ml vs. 1.47(1.15, 2.88)pg/ml, Z=-5.51, P<0.001]、IFN-γ[3.79(2.93, 5.05)pg/ml vs. 1.50(1.31, 2.09)pg/ml, Z=-7.12, P<0.001]、TNF-α[2.14 (1.56, 3.11)pg/ml vs. 0.27(0.00,1.43)pg/ml, Z=-6.84, P<0.001] were markedly elevated. ⑤Correlation analysis revealed a positive relationship between IL-17 and Th17 cells ( r=0.49, P<0.001) as well as between Th17/Treg ( r=0.37, P=0.006). Conclusion:Patients with SAPHO syndrome exhibit an increased ratio of proinflammatory Th17 cells leading to immune imbalance and disturbances in proinflammatory and anti-inflammatory cytokine levels, which may contribute to disease development. The reduction in IL-2 levels indicates a deficiency in IL-2 and decreased inhibition of Th17 cells, resulting in Th17/Treg immune imbalance, suggesting that low-dose IL-2 therapy could be beneficial to patients with SAPHO.
