Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

With the widespread useof immune checkpoint inhibitors(ICIs)in the treatment of various solid tumors,immune-related adverse events have attracted increasing clinical attention.Although ICI-associated myocarditis is rare,it typically has an insidious onset,progresses rapidly,and carries a high mortality rate,making it one of the most severe complications of ICI therapy.Early recognition and management remain challenging due to the absence of standardized diagnostic and therapeutic guidelines.ICI-associated myocarditis is characterized by the following features,with symptom onset commonly occurring within weeks of initiating ICI therapy.Its clinical manifestations are often non-specific and can be misdiagnosed as coronary artery disease or viral myocarditis.Prompt administration of high-dose corticosteroids combined with immunosuppressants,cardiac rhythm and functional support,is crucial for effective management.Although numerous stud-ies highlight the importance of early detection and multidisciplinary collaboration,there is still no consensus on standardized treatment pro-tocols.This report describes a case of acute ICI-associated myocarditis with ovarian cancer who developed symptoms after receiving com-bined apalutamide and toripalimab therapy.The patient responded well to corticosteroid pulse therapy,second-line immunosuppressants,and intensive care support.Due to recurrent ventricular arrhythmias,an implantable cardioverter defibrillator was placed,and cardiac func-tion remained stable during follow-up.Through this case and a review of the relevant literature,we discuss the clinical features,compre-hensive treatment strategies,and long-term management approaches for ICI-associated myocarditis,aiming to raise clinical awareness,pro-mote standardized multidisciplinary team collaboration,and ultimately improve patient outcomes.

OBJECTIVE To investigate the diagnosis and treatment of small cell neuroendocrine carcinoma(SNEC)of nasal cavity and paranasal sinuses.METHODS The clinical data of 5 patients with SNEC diagnosed at Tianjin People's Hospital and Medical University General Hospital from December 2016 to August 2022 were retrospectively analyzed.There were 4 male patients and 1 female patient.The age range was 40-70 years,with an average age of 55 years.Among them,there were 4 stage ⅣA and 1 stage ⅣC.Two patients underwent surgery plus radiotherapy and chemotherapy,one patient underwent radiotherapy followed by chemotherapy,one patient underwent concurrent radiotherapy and chemotherapy,and one patient refused treatment.The follow-up period was 4-60 months.RESULTS By the end of the follow-up,2 patients died,2 patients relapsed,and 1 patient had no recurrence.CONCLUSION Nasal cavity and paranasal sinus neuroendocrine tumors are rare,and small cell neuroendocrine carcinoma is even rarer.The clinical symptoms are not typical,and it is usually discovered at an advanced stage.The malignancy is high,and it is generally treated with a comprehensive approach that includes radiotherapy and chemotherapy.The treatment effect is poor.

Objective To investigate the correlation between the anterior ethmoidal artery(AEA)and anatomical variations of the anterior cranial base,and to analyze the predictive factors for AEA suspension.Methods Sinus CT imaging data of 159 patients undergoing endoscopic sinus sur-gery(ESS)were retrospectively analyzed.Mimics 21.0 software was utilized for three-dimensional reconstruction,measuring parameters of AEA and anterior cranial base anatomy and performing classi-fication.Pearson and Spearman correlation analyses were used to evaluate the correlations among vari-ous anatomical parameters and their classifications.Multivariate binary logistic regression analysis was performed to screen for independentpredictive factors of AEA suspension.Results The rates of AEA suspension differed significantly across different Keros classifications(P＜0.001),with an increase rate as the Keros classification level increased(P＜0.001).The transverse diameter,height and vol-ume of supraorbital ethmoid cells(SOEC),olfactory fossa depth,lateral lamella of the cribriform plate(LLCP)length and frontal sinus pneumatization classification grade were positively correlated with the distance from AEA to the cranial base(P＜0.05).Multivariate binary Logistic regression analysis showed that the presence of SOEC(OR=4.178,95％CI,2.517 to 6.935,P＜0.001),in-creased olfactory fossa depth(OR=1.433,95％CI,1.197 to 1.715,P＜0.001),and higher frontal sinus pneumatization classification grade(OR=1.621,95％CI,1.121 to 2.345,P=0.01)were independent predictive factors for AEA suspension.Conclusion Detailed preoperative CT imaging assessment,especially the analysis of SOEC,olfactory fossa depth and frontal sinus pneumatization classification,aids in accurately assessing the anatomical position of AEA,thereby effectively reduc-ing the risk of AEA injury,and improving the safety and success rate of surgery.

The global distribution of medical resources is uneven and organ shortages are becoming increasingly serious. ASEAN countries have been working hard to explore and promote local organ transplantation in order to alleviate the serious imbalance between organ donation and organ transplantation needs. However, the development of cadaveric organ donation varies among ASEAN countries, and the cadaveric organ donation rate in most countries is generally low. Since 1991, China and ASEAN have evolved from dialogue to strategic cooperation, then to a community with a shared future, and further to a comprehensive strategic partnership, all demonstrating broad prospects for cooperation. This article analyzes the current situation and challenges of organ donation and transplantation in ASEAN countries, combining field visits and its own experience, and proposes strategies for strengthening international cooperation, optimizing policy environment, enhancing technical capabilities, and increasing public awareness in the field of organ donation and transplantation under the China-ASEAN development strategy framework. The aim is to build a more equitable, efficient, and sustainable organ donation and transplantation system, contributing to the realization of global public health security and a community of common health for mankind.

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. Surgical resection remains the preferred treatment modality, offering the potential for cure. However, over half of HCC patients present as intermediate to advanced stages at diagnosis, with multiple factors precluding surgical resection. Conversion therapy represents an important treatment strategy by enabling tumor downstaging, offering future resectability for patients with intermediate-to-advanced HCC who are initially unresectable. This article reviews the relevant concepts and research progress in conversion therapy for HCC.

Objective:To investigate the molecular mechanism of miR-886-5p targeting BCL-2-associated X protein (BAX) to inhibit the proliferation, migration, and invasion of liver cancer cells.Methods:mRNA expression data of HCC patients were obtained from the Starbase database, including 370 liver cancer samples and 50 normal liver tissue samples adjacent to the cancer. Analyze the expression of miR-886-5p in the previously obtained data and investigate the relationship between miR-886-5p and BAX in liver cancer samples. After transfection of the corresponding plasmids into Huh7 and HepG2 cells, the following groups were established. Analyze the interaction between miR-886-5p and BAX in vitro, detect the protein expression by Western blotting, and verify the targeting relationship between the two by dual luciferase reporter gene assay.Results:Starbase database analysis found that the standardized expression level of miR-886-5p in 370 liver cancer samples was lower than that in normal liver tissue samples (0.12±0.07 vs. 0.73±0.27, t=-15.71, P<0.001), and the expression level of miR-886-5p was positively correlated with the expression level of BAX ( r=0.152, P=0.003). qRT-PCR analysis showed that the expression level of miR-886-5p in HL-7702 cells was higher than that in Huh7 (4.57±0.06 vs. 1.61±0.40, t=32.48) and HepG2 (4.57±0.06 vs. 1.03±0.13, t=143.9), and the expression level of BAX in HL-7702 cells was higher than that in Huh7 (4.01±0.12 vs. 1.28±0.09, t=82.20) and HepG2 (4.01±0.12 vs. 1.30±0.11, t=80.76), the differences were statistically significant (all P<0.001). The proliferation, migration, and invasion abilities of Huh7 and HepG2 cells decreased after transfection with miR-886-5p mimics, while the expression levels of BAX at the mRNA and protein levels increased. However, after inhibiting the expression of miR-886-5p, the above indicators of cells were the opposite, and the dif-ferences were statistically significant (all P<0.05). The viability, EdU positivity rate, cell migration rate, and number of transmembrane cells in the miR-886-5p+ BAX group were lower than those in the BAX group, and the relative expression levels of miR-886-5p, BAX mRNA, and BAX protein were higher than those in the BAX group. However, the above indicators in the Sponge+ BAX group showed opposite trends, and all differences were statistically significant (all P<0.05). There was a targeted binding site between miR-886-5p and BAX. Conclusion:Both miR-886-5p and BAX are downregulated in liver cancer, and miR-886-5p inhibits the proliferation, migration, and invasion of liver cancer cells by targeting BAX.

Tripterygium wilfordii multiglucoside,the primary active constituent of the Chinese materia medica of Tripterygium wilfordii,has anti-inflammatory and immune-regulation properties and is widely used to treat kidney and rheumatic and immunological diseases.However,the potential adverse effects of Tripterygium wilfordii multiglucoside on pediatric gonadal development have limited its clinical application in pediatrics.According to the traditional Chinese medicine theory,the reproductive toxicity of Tripterygium wilfordii is closely associated with deficiency in kidney essence and tian gui disorder.Based on the"kidney essence-tian gui"theory,this study elucidates the transformation of"kidney essence to tian gui"through the qi transformation of"original noumenon to supreme ultimate,"which is synergistically regulated by the accumulation of kidney qi,consolidation of spleen qi,and conveyance and dispersion of liver qi.It is channeled through the interconnected pathways of the thoroughfare channel,conception channel,and governor channel.The physiological process of"kidney essence to tian gui"is damaged by the bitter,cold,and toxicity of Tripterygium wilfordii,leading to kidney asthenia,spleen deficiency,liver depression,and meridian stagnation,causing tian gui dysregulation.Therefore,this study offers traditional Chinese medicine prevention and treatment strategies for pediatric medication safety,including nourishing the kidney essence to replenish the tian gui source,enhancing the middle jiao to strengthen the tian gui guard,regulating liver qi to promote the operation of tian gui,and unblocking the thoroughfare channel,conception channel,and governor channel to ensure the unobstructed pathway of tian gui.

Objective:To investigate the incidence of shoulder work-related musculoskeletal disorders (WMSDs) among occupational population in China, and to explore their intrinsic association with personal and work-related factors.Methods:In April 2024, 73497 valid questionnaires of the Chinese version of the Musculoskeletal Disorders Electronic Questionnaire were retrospectively analyzed from June 2018 to December 2023 in 22 provinces and 29 key industries in China, and the general information, occurrence of WMSDs and related risk factors of key occupational populations in different regions in China were collected. By using Chi-square test and confirmatory factor analysis, the relationship between shoulder fatigue and pain in key occupational groups and individual factors, work type, work posture and work organization was discussed, and the internal relationship was analyzed based on structural equation model.Results:Higher incidence of shoulder fatigue and pain were associated with female, lack of physical exercise, uncomfortable working posture and neck leaning forward ( P<0.05). Structural equation model analysis showed that work type, work posture and work organization were strongly correlated ( r=0.58, 0.55). Work organization and work type were strongly correlated with shoulder fatigue ( r=0.65) and moderately correlated with shoulder fatigue ( r=0.21). Shoulder fatigue was moderately associated with shoulder pain ( r=0.40). Individual factors, work type, work posture and shoulder fatigue could directly affect shoulder pain ( OR=0.07, -0.09, 0.17 and 0.40), and work type and work posture could also indirectly affect shoulder pain through shoulder fatigue ( OR=0.08, 0.03). Work organization only indirectly affected shoulder pain through shoulder fatigue ( OR=0.26) . Conclusion:The main influencing factor of shoulder pain is shoulder fatigue, followed by work posture and individual factors. Structural equation model can better reflect the complex relationship between work type, work posture and work organization and shoulder WMSDs. Improving work posture and work organization may be an effective way to control the influence of shoulder fatigue on shoulder pain.

Objective:To explore the structural equation model to explore the levels of work-related musculoskeletal disorders (WMSDs) and various risk factors in the feet and ankle of China's occupational population, providing scientific basis for for preventing WMSDs in feet and ankles.Methods:Data of 73497 national occupational epidemiological cases were selected from June 2018 to December 2023 used the Chinese version of the Electronic Questionnaire on Musculoskeletal Disorders. The adverse ergonomic factors and their source classification standard and confirmatory factor analysis were used to investigate foot and ankle WMSDs and their related risk factors (including individual factors, work organization, work posture, work type, fatigue, etc.) in key occupational groups in China, and structural equation model hypothesis, fitting, verification, and path and intermediary effect analysis were carried out. The model fit evaluation indexes included Chi-square specific degrees of freedom ( χ2/ df), gauge fit index (NFI), Tucker Lewis index (TLI), goodness of Fit index (GFI), adjusted Goodness of Fit index (AGFI) and approximate root mean square error (RMSEA) . Results:A total of 73497 occupational workers were surveyed, with local muscle fatigue and WMSDs incidence rates in the feet and ankles being 17.17% and 12.06%, respectively. The fitting index of the adjusted structural equation model basically meets the standard (GFI=1, AGFI=1, RMESA=0.042, NFI=0.716, TLI=0.663). The top three factors affecting feet and ankle WMSDs are feet and ankle muscle fatigue, work type, and work organization, with standardized path coefficients of 0.221, 0.105, and 0.095, respectively. The top two factors affecting feet and ankle muscle fatigue are work organization and work type, with standardized path coefficients of 0.548 and 0.383, respectively. Feet and ankle muscle fatigue, work type, work organization, and work posture have a direct effect on feet and ankle WMSDs, with effect values of 0.221, 0.105, 0.095, and 0.077, respectively. The organization and type of work can also have indirect effects through feet and ankle muscle fatigue, with effect values of 0.121 and 0.084, respectively.Conclusion:Feet and ankle muscle fatigue has a direct impact on WMSDs, and plays a mediating role between ankle and ankle WMSDs caused by work organization and work type. Feet and ankle muscle fatigue is an important pathway leading to feet and ankle WMSDs. It is recommended that employers and managers detect job fatigue early and take corresponding prevention and intervention measures, which can play a key role in preventing feet and ankle WMSDs.
