Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Objective To analyze the disability level and long-term care needs assessment policies issued by 49 pilot cities in China's long-term care insurance system,providing insights for further improvement of the system.Methods Policy documents related to long-term care insurance,published between June 2016 and December 2024 on official platforms of local governments,the Ministry of Human Resources and Social Security,the National Healthcare Security Administration,and the National Public Service Platform for Standards Information,were retrieved.A comparative analysis was used to summarize and compare the content of these policy texts.Results Currently,there are 49 pilot cities implementing the long-term care insurance system in China.47 cities have issued disability level assessment standards,with 38 cities adopting the trial standards issued by the National Healthcare Security Administration.In 42 pilot cities,the disability level assessment includes indicators such as activities of daily living,cognitive function,and sensory and communication abilities.22 cities have issued policies related to care needs assessment.In most cities,the care needs assessment partially or fully includes indicators from the disability level assessment.Conclusion There is no national uniformity in disability level assessment standards,and the care needs assessment framework needs further improvement.It is recommended to standardize disability level assessment criteria,clearly delineate the boundaries and content of disability level and care needs assessments,and enhance the development of the care needs assessment system.

As an independent first-level discipline,an appropriate classification of nursing science is significant.In China,each nursing degree-granting institution has developed its own secondary-level discipline directions based on its research characteristics and strengths,with varying names and research scopes.Furthermore,there is no unified global classification system.This paper,based on the characteristics of nursing as a discipline and combined with China's discipline classification principles,used literature analysis,comprehensive classification,philosophical reflection,logical reasoning,and expert consultation methods to explore the connotation of nursing,its unique research objects and scope,and to construct a secondary-level discipline classification system for nursing science that is suitable for China's national conditions.The paper also discussed the challenges faced by the nursing discipline and its future development directions,providing theoretical and practical guidance for the development of the nursing discipline.

Microplastics(MPs)and nanoplastics(NPs)have become hazardous materials due to the massive amount of plastic waste and disposable masks,but their specific health effects remain uncertain.In this study,fluorescence-labeled polystyrene NPs(PS-NPs)were injected into the circulatory systems of mice to determine the distribution and potential toxic effects of NPs in vivo.Interestingly,whole-body imaging found that PS-NPs accumulated in the testes of mice.Therefore,the toxic effects of PS-NPs on the reproduction systems and the spermatocytes cell line of male mice,and their mechanisms,were investigated.After oral exposure to PS-NPs,their spermatogenesis was affected and the spermatogenic cells were damaged.The spermatocyte cell line GC-2 was exposed to PS-NPs and analyzed using RNA sequencing(RNA-seq)to determine the toxic mechanisms;a ferroptosis pathway was found after PS-NP exposure.The phenomena and indicators of ferroptosis were then determined and verified by ferroptosis inhibitor ferrostatin-1(Fer-1),and it was also found that nuclear factor erythroid 2-related factor 2(Nrf2)played an important role in spermatogenic cell ferroptosis induced by PS-NPs.Finally,it was confirmed in vivo that this mechanism of Nrf2 played a protective role in PS-NPs-induced male reproductive toxicity.This study demonstrated that PS-NPs induce male reproductive dysfunction in mice by causing spermatogenic cell ferroptosis dependent on Nrf2.

OBJECTIVE To investigate the efficacy and safety of domestic Paliperidone extended-release tablets as a substitute for original Paliperidone extended-release tablets in the treatment of stable schizophrenia. METHODS A total of 65 patients with schizophrenia， who were treated with single original Paliperidone extended-release release tablets for 2 months or more in the outpatient or inpatient department of Shandong Daizhuang Hospital from June 2021 to June 2022， were collected and randomly divided into the domestic group （33 cases） and the original group （32 cases）. The domestic group was treated with the same dose of domestic Paliperidone extended-release tablets instead for 2 months， and the original group continued to use the previous dose of the original drug for 2 months. Positive and negative syndrome scale （PANSS） and treatment emergent symptom scale （TESS） were used to evaluate the two groups at the time of enrollment and the end of 1 week， 1 month and 2 months after enrollment. The incidence of ADR was calculated at the end of 2 months after enrollment. The fasting blood glucose， blood lipid indicators （triglyceride， total cholesterol， low-density lipoprotein， high-density lipoprotein， very-low-density lipoprotein）， serum prolactin levels， and paliperidone blood concentration were determined after the intravenous blood sample was collected. The ratio of paliperidone blood concentration to dose （C/D value） was calculated， and an electrocardiogram was performed. RESULTS There were 31 and 30 patients in the domestic group and the original group who completed the trial， respectively. There were no statistical significances in PANSS score， TESS score or C/D value at the time of enrollment and the end of 1 week， 1 month and 2 months after enrollment； there were no statistical significances in the levels of fasting blood glucose， blood lipid or serum prolactin at the time of enrollment and at the end of 2 months after enrollment （P＞0.05）. PANSS scores of both groups significantly decreased at the end of 1 month and 2 months after enrollment （P＜0.01）. The incidences of ADR were 25.81% in the domestic group and 30.00% in the original group， without significant difference （P＞0.05）， and there were no significant abnormalities in the electrocardiograms of the two groups. CONCLUSIONS Domestic Paliperidone extended-release tablets can directly replace the original tablets in the treatment of stable schizophrenia， and their clinical efficacy and safety are comparable.
