Organ donation by minors has long been a highly controversial topic in both legal and ethical discussions worldwide. In the United States, case law has established a case-by-case review mechanism, allowing limited room for the practice of living organ donation by minors under specific conditions. Germany, with a strong emphasis on the protection of personal dignity, adopts a more cautious stance. In China, the law clearly stipulates that living organ donors must possess full civil capacity. However, some scholars argue that under strict conditions and with adequate safeguards, minors should be allowed to donate organs in emergency medical situations. Given the limited domestic experience in this area, China should develop a protective pathway that balances scientific validity, legal compliance, and humanistic concern, in line with its national conditions, legal traditions and cultural background, all under the guidance of the principle of caution. Based on a review of China’s current organ donation system, this article examines legislative philosophies, procedural designs and ethical review mechanisms in the U.S. and Germany. From a comparative law perspective, it extracts institutional elements that could serve as references, with the aim of improving China’s legal framework for organ donation by minors.

ObjectiveTo optimize the extraction method for polysaccharides from turnip（Brassica rapa）， and analyze and evaluate the primary structure of the isolated and purified turnip polysaccharide fraction（BP-1） and its hypoglycemic effects in diabetic zebrafish. MethodsTaking polysaccharide yield as the evaluation index， a semi-bionic extraction method was employed. Single-factor experiments and Box-Behnken response surface methodology were used to investigate three factors of solid-to-liquid ratio， extraction time and extraction temperature， in order to optimize the extraction process. BP-1 was isolated and purified using the Sevage method and DEAE-52 cellulose column chromatography. Structural characterization of the turnip polysaccharides was performed using ultraviolet-visible spectrophotometry（UV）， gas chromatography-mass spectrometry（GC-MS）， Congo red assay， and Fourier-transform infrared spectroscopy（FT-IR） to determine purity， monosaccharide composition， triple-helix structure， and functional groups. The microstructure of the polysaccharides was observed using scanning electron microscopy（SEM） and atomic force microscopy（AFM）. Zebrafish were divided into the blank group（adding E3 medium）， and BP-1-1， BP-1-10， BP-1-50， BP-1-200， BP-1-1 000 groups（adding BP-1 solutions at concentrations of 1， 10， 50， 200， 1 000 mg·L^-1， respectively）， and zebrafish embryos were subjected to a 96-hour exposure experiment. The maximum tolerated concentration of BP-1 in zebrafish was determined by evaluating its effects on phenotype， survival rate， malformation rate， and heart rate. Experimental animals were randomly divided into the blank group， model group， BP-1-10 group（10 mg·L^-1）， BP-1-50 group（50 mg·L^-1）， and BP-1-200 group（200 mg·L^-1）. The blank group was cultured in E3 medium， the model and treatment groups were induced to establish a diabetic model in 4 day-post-fertilization（dpf） zebrafish embryos using 10 g·L^-1 of glucose combined with 500 µmol·L^-1 of alloxan. The treatment groups received corresponding doses of BP-1 solution， while the blank and model groups received an equal volume of saline. Glucose and insulin（INS） levels were measured using enzyme-linked immunosorbent assay（ELISA） kits， the effects on the liver were observed by hematoxylin-eosin（HE） histopathological sections. The mRNA expression levels of glucagon（Glucagon）， insulin（Insa）， and phosphoenolpyruvate carboxykinase 1（PCK1） were detected with real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）. ResultsThe optimized extraction conditions were determined as follows：solid-to-liquid ratio of 1∶40（g·mL^-1）， extraction time of 66 min， and extraction temperature of 79 ℃. Under these conditions， the yield of turnip polysaccharides was （10.34±0.96）%. UV analysis indicated that BP-1 contained no proteins or nucleic acids， GC-MS analysis revealed that BP-1 consisted of six monosaccharides（arabinose， rhamnose， ribose， mannose， galactose and glucose）. Congo red assay indicated that the molecular conformation did not exhibit a triple-helix structure， FT-IR analysis showed the presence of α-glycosidic bonds and uronic acids， SEM analysis revealed an irregular flaky structure with a flat and smooth surface， AFM analysis suggested that the aggregated structure might be formed by the entanglement of molecular chains and intramolecular hydrogen bonding. The maximum tolerated concentration of BP-1 in zebrafish over 96 h was determined to be 200 mg·L^-1. Pharmacodynamic results showed that， compared with the blank group， the model group exhibited significantly increased glucose levels and significantly decreased INS levels（P<0.01）. Compared with the model group， the BP-1-50 group significantly reduced glucose levels and increased INS levels（P<0.05）. Histopathological examination of liver tissue revealed that various doses of BP-1 had a certain reparative effect on damaged liver tissue. The liver tissue structure in the BP-1-200 group was nearly normal， with hepatocytes appearing plump. Real-time PCR results showed that， compared with the blank group， the model group exhibited significantly upregulated mRNA expressions of Glucagon and PCK1， and significantly downregulated mRNA expression of Insa（P<0.01）. Compared with the model group， the BP-1-50 and BP-1-200 groups showed significantly downregulated mRNA expressions of Glucagon and PCK1， and significantly upregulated mRNA expression of Insa（P<0.01）. ConclusionThe semi-bionic extraction method for turnip polysaccharides yields a high extraction rate， is simple to operate， has low costs， making it suitable for large-scale industrial production. BP-1 consists of six monosaccharides， contains α-glycosidic bonds and uronic acids， exhibits hypoglycemic activity， and provides a certain protective effect on the liver of alloxan-induced diabetic model zebrafish.

Background As one of the primary operational methods in the power grid industry, the insulated glove working method imposes significant physical demands due to the constraints of insulating equipment and specific required postures, resulting in substantial occupational health hazards among workers in this sector, which have garnered widespread social attention. Objective To investigate the prevalence and influencing factors of work-related musculoskeletal disorders (WMSDs) in the neck, shoulder, and lumbar regions among workers wearing insulated gloves, and to provide targeted measures to reduce occupational hazards. Methods Using stratified cluster sampling, 1079 frontline workers were randomly selected from power supply enterprises across 3 provinces in China. The revised Chinese version of the Musculoskeletal Disorders Questionnaire was used to investigate the 1-year prevalence of WMSDs in the neck, shoulder, and lumbar regions among workers wearing insulated gloves, and to collect factors associated with multi-site WMSDs (defined as involvement of ≥2 sites among the neck, shoulder, and lumbar). Results The 1-year prevalence of WMSDs in the neck, shoulder, and lumbar regions was 39.9%, 30.0%, and 25.3%, respectively, with a multi-site WMSDs prevalence of 32.0%. Multiple logistic regression analysis showed that, compared to workers with technical secondary school education or senior high school education and below, workers with junior college education or bachelor’s degrees and above had a higher risk of multi-site WMSDs (OR=2.12, 95%CI: 1.47, 3.06). Compared to workers with <10 years of work experience, those with 10-<20 years of work experience had a higher risk of multi-site WMSDs (OR=1.96, 95%CI: 1.45, 2.67). Working in uncomfortable postures "sometimes" (OR=1.64, 95%CI: 1.14, 2.36), "frequently" (OR=2.75, 95%CI: 1.76, 4.29), and "very frequently" (OR=3.55, 95%CI: 2.04, 6.19) were significantly associated with an increased risk of multi-site WMSDs compared to never working in such postures. Frequent repetitive movements of the low back (OR=2.05, 95%CI: 1.48, 2.84) increased the risk of multi-site WMSDs, while sufficient rest time decreased the risk (OR=0.45, 95%CI: 0.34, 0.61). Conclusion The prevalences of single-site and multi-site WMSDs in the neck, shoulder, lumbar regions are relatively high among workers wearing insulated gloves. Factors associated with multi-site WMSDs include 10-<20 years of work experience, junior college education or bachelor’s degrees and above, uncomfortable working postures, frequent repetitive low-back movements, and lack of sufficient rest time.

Background In recent years, the detection rate of thyroid nodules in China's occupational population has shown an upward trend. The prevalence of this disease needs to be taken seriously and targeted measures should be taken to address its influencing factors. Objective To analyze the detection and influencing factors of thyroid nodules among adult male workers in coal mining enterprises in Shanxi Province, and provide a theoretical basis for the prevention of thyroid nodules. Methods A total of 5195 adult male workers from coal mining enterprises who ordered physical examination provided by the Xishan Coal Electricity (Group) Corporation Occupational Disease Prevention and Control Institute in Taiyuan City, Shanxi Province from May 2023 to December 2023 were selected as research subjects. A questionnaire survey, physical examination, ultrasound examination, and biological sample collection and testing were conducted. Thyroid nodules were diagnosed based on ultrasound results, classified and evaluated according to the Chinese-Thyroid Imaging Reporting and Data System (C-TIRADS), and the crude detection rate and standardized detection rate of thyroid nodules in adult male coal mine workers in Shanxi Province wereestimated. Occupational history and occupational exposure information were retrieved from their annual occupational health examination reports provided by the employer. Logistic regression modeling was used to analyze the influencing factors of thyroid nodule. Results A total of 1688 cases of thyroid nodules were detected, with a crude detection rate of 32.49% and an age-standardized detection rate of 31.17%. The cases (constitution ratio) of thyroid nodules by category in the detected cases was as follows: 358 cases (21.21%) were classified as category 2, 1261 cases (74.70%) as category 3, 67 cases (3.97%) as category 4a, and 2 cases (0.12%) as category 4b. The results of logistic regression showed that the duration of exposure to occupational hazards for 11-20 years, 21-30 years, ≥31 years, average monthly working>26 days, and shift work were positively correlated with the detection of thyroid nodules (P<0.05), and the associated ORs (95%CIs) were 1.29 (1.01, 1.65), 1.55 (1.20, 1.99), 1.68 (1.26, 2.55), 1.19 (1.00, 1.40), and 1.15 (1.02, 1.29), respectively. Conclusion The duration of exposure to occupational hazards, average monthly working days, and shift work are influencing factors of thyroid nodules. Intervention measures should be developed based on these influencing factors to prevent the occurrence of thyroid nodules.

Objective To investigate the role of transcription factor EB(TFEB)in endotoxin-tolerant macrophages.Methods The RAW264.7 cells were divided into blank group(DMEM medium),LPS 5 group(5 ng/mL LPS treatment for 4 h),LPS 100 group(100 ng/mL LPS treatment for 4 h),and tolerance group(5 ng/mL LPS for 12 h followed by 100 ng/mL LPS for 4 h).The releases of inflammatory factors TNF-α and IL-6 were measured using ELISA.Western blotting and immunofluorescence assay were used to evaluate the distribution of autophagy-related proteins LC3 and P62,as well as TFEB in the cytoplasm and nucleus.Lentiviral overexpression of TFEB or siRNA-mediated knockdown of TFEB were performed to observe the changes in autophagy levels and bacterial clearance ability in the tolerant cells.Results The cells in the tolerance group had significantly lower contents of TNF-α and IL-6,as well as reduced bacterial clearance ability(P<0.01),down-regulated LC3 expression while up-regulated P62 level,and decreased expression of TFEB in both the cytoplasm and nucleus(P<0.01)when compared with the cells of the LPS 100 group.Overexpression of TFEB significantly increased LC3 level,reduced P62 level,and enhanced bacterial clearance ability in the endotoxin-tolerant cells(P<0.01).In contrast,siRNA-mediated knockdown of TFEB had no significant impacts on LC3 and P62 expression levels or bacterial clearance ability.Conclusion Overexpression of TFEB can restore the autophagy of endotoxin-tolerant cells and enhance their bacterial clearance capacity,thereby alleviating the immunosuppressive state of sepsis.These findings suggest that TFEB holds promise as a potential therapeutic target for the prevention and treatment of sepsis.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.
