ObjectiveTo investigate the potential mechanism of Danggui Buxuetang (DBT) in the treatment of vascular dementia (VAD). MethodsSixty male SD rats were randomly assigned to the sham-operated group, model group, DBT low-, medium-, and high-dose groups, and the donepezil group. Except for the sham-operated group, rats in all other groups underwent bilateral common carotid artery ligation. After successful modeling, DBT was administered at doses of 9.2, 18.4, 36.8 g·kg-1 for the low-, medium-, and high-dose groups, respectively, while the donepezil group received 3 mg·kg-1 donepezil solution by gavage once daily. After 4 consecutive weeks of drug treatment, rats underwent the Morris water maze test, novel object recognition test, Nissl staining to observe hippocampal neurons, and immunofluorescence staining to detect the expression of neuronal nuclear protein (NeuN) in the hippocampus. Western blot was used to assess the expression of PTEN-induced kinase 1 (PINK1), Parkin, microtubule-associated protein 1 light chain 3Ⅱ (LC3Ⅱ), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax). Transmission electron microscopy was used to observe hippocampal neuronal ultrastructure. Real-time PCR was used to detect the expression of NADPH oxidase subunits p22phox and p47phox in hippocampal tissues. The levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and total antioxidant capacity were measured to evaluate oxidative stress levels. ResultsIn the Morris water maze test, escape latency changed significantly over time in all groups except the model group. Compared with the sham-operated group, the model group showed significantly prolonged escape latency (P<0.01). Compared with the model group, rats in the DBT groups and the donepezil group exhibited significantly shorter escape latency (P<0.05, P<0.01). The number of crossings over the original platform was significantly reduced in the model group compared with the sham-operated group (P<0.01), whereas rats in the DBT and donepezil groups showed significantly increased platform crossings compared with the model group (P<0.05, P<0.01). Compared with the sham-operated group, exploration time of new objects was significantly reduced in the model group (P<0.01). Compared with the model group, exploration time of new objects increased significantly in the medium- and high-dose DBT groups and the donepezil group (P<0.05, P<0.01), while no significant change was observed in the low-dose DBT group. Compared with the high-dose DBT group, rats in the donepezil group had significantly prolonged escape latency and reduced platform crossings and new-object exploration time (P<0.05). Nissl staining showed decreased density of healthy neurons in the CA1 and CA3 regions of the hippocampus in the model group, with loss of Nissl bodies and nuclear atrophy or disappearance. In the high-dose DBT group, neuronal density in CA1 and CA3 increased, with neurons arranged closely and displaying normal morphology. Immunofluorescence showed that compared with the sham-operated group, the hippocampal NeuN⁺ cell count in the VAD model group was significantly decreased(P<0.01), compared with the VAD model group, the hippocampal NeuN⁺ cell count in the high-dose DBT group was significantly increased(P<0.01). Compared with the sham-operated group, the expression of PINK1, Parkin, LC3Ⅱ, and Bax proteins was significantly increased(P<0.01), while the expression of Bcl-2 was significantly decreased in the VAD model group(P<0.01). Compared with the VAD model group, the high-dose DBT group showed significantly decreased expression of PINK1, Parkin, LC3Ⅱ, and Bax proteins(P<0.01)and significantly upregulated Bcl-2 expression(P<0.01). The medium-dose DBT group exhibited significantly reduced expression of Parkin, LC3Ⅱ, and Bax proteins(P<0.05,P<0.01) and significantly increased Bcl-2 expression(P<0.01), while no statistically significant differences were observed in the low-dose DBT group. Transmission electron microscopy showed mitochondrial pyknosis, thickened cristae, increased electron density, and the presence of mitochondrial autophagy in the model group. In contrast, hippocampal neurons in the high-dose DBT group contained abundant mitochondria with intact morphology, clear cristae, and uniform matrix. Compared with the sham-operated group, total antioxidant capacity, SOD activity, and GSH levels were significantly decreased, while MDA levels were significantly increased in the model group (P<0.01). Compared with the model group, total antioxidant capacity and antioxidant levels (SOD, GSH) increased significantly, and MDA decreased significantly in the medium- and high-dose DBT groups (P<0.01), while no significant changes were observed in the low-dose DBT group. Compared with the sham-operated group, mRNA expression of p22phox and p47phox was significantly increased in the model group (P<0.01). Compared with the model group, expression of p22phox and p47phox was significantly decreased in the DBT groups (P<0.05, P<0.01). ConclusionDBT may exert neuroprotective effects by regulating PINK1/Parkin-mediated mitochondrial autophagy, thereby improving learning and memory abilities and treating VAD.

ObjectiveTo explore the efficacy and mechanisms of Sini San in the treatment of depression and liver injury based on gut microbiota. MethodsThirty-two male Sprague-Dawley (SD) rats were randomly divided into a normal group, model group (M), Sini San group (MS, 2.5 g·kg-1), and fluoxetine group (MF, 2 mg·kg-1). Except for the normal group, rats in the other three groups were subjected to chronic unpredictable mild stress (CUMS). After 8 weeks, the open-field test and sucrose preference test were conducted. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum corticosterone (CORT), adrenocorticotropic hormone (ACTH), corticotropin-releasing factor (CRF), lipopolysaccharide (LPS), Zonulin, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), γ-aminobutyric acid (GABA) levels in the hippocampus and prefrontal cortex, and brain-derived neurotrophic factor (BDNF) levels in the hippocampus. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect hippocampal BDNF mRNA expression. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured using the ultraviolet lactate dehydrogenase method. The ultrastructure of the intestinal epithelium was observed by electron microscopy, and gut microbiota in rat feces were analyzed using 16S rDNA high-throughput sequencing. ResultsCompared with the normal group, the sucrose preference of rats in the model group was significantly reduced (P0.01), whereas it was significantly increased in the Sini San group compared with the model group (P0.05). Compared with the normal group, hippocampal GABA protein levels and BDNF mRNA expression in the model group were significantly decreased (P0.05), and compared with the model group, both were significantly increased in the Sini San group (P0.05, P0.01). Compared with the normal group, serum LPS and Zonulin levels in the model group were significantly increased (P0.05, P0.01), and compared with the model group, Zonulin levels in the Sini San group were significantly decreased (P0.05). No obvious changes were observed in the ultrastructure of the jejunal mucosa among groups. Compared with the normal group, widened and blurred tight junctions, sparse and shortened microvilli, and mitochondrial swelling with cristae disruption in epithelial cells were observed in the ileal and colonic mucosa of the model group, which were markedly improved in the Sini San and fluoxetine groups. The results of 16S rDNA high-throughput sequencing showed that Sini San improved CUMS-induced dysbiosis of Bacteroidetes and Proteobacteria. Correlation analysis indicated that Bacteroidetes and Proteobacteria were significantly correlated with depression-related indicators, liver function, and intestinal mucosal permeability. ConclusionSini San exerts antidepressant and hepatoprotective effects by improving Bacteroidetes and Proteobacteria and inhibiting the increase in intestinal mucosal permeability in CUMS rats.

Chinese Journal of School Health 2025;46(1):18-23
Objective:
To analyze the status of outdoor activities on weekends among children and adolescents of different educational stages in Shanghai and their impact on myopia, so as to provide a basis for formulating more specific prevention and control protocol of myopia.
Methods:
From September to October 2022, a stratified cluster random sampling method was employed to select 84 schools (27 kindergartens, 21 primary schools, 15 junior high schools and 21 high schools) across Shanghai, enrolling a total of 28 654 children and adolescents aged 4 to 18 for the study. Ophthalmic examinations were conducted to ascertain the prevalence of myopia among children and adolescents. Additionally, a questionnaire survey was administered to collect data on outdoor activity duration and associated factors. Multivariate Logistic regression analysis was utilized to investigate the associated factors of outdoor activity levels on weekends.
Results:
The overall myopia detection rate among children and adolescents was 58.4%, with a higher rate observed in girls (59.2%) compared to boys (57.6%). The myopia detection rates for children and adolescents with an average daily outdoor activity duration of ≥2 h and <2 h on weekends were 54.6% and 68.8%, and the differences were statistically significant ( χ 2=8.12,460.89, P <0.01). Multivariable Logistic regression analysis revealed that girls ( OR =0.80), those with a myopic parent ( OR =0.68), schools from urban districts ( OR =0.72), higher education stages (primary school: OR =0.65, junior high school: OR =0.24, high school: OR =0.14) and spending≥2 h/d on homework during weekends ( OR =0.57) among children and adolescents were less likely to engage in outdoor activities for ≥2 h on weekends ( P <0.01). After incorporating gender, parental myopia status, educational stage, school location, average daily duration on weekends for spending on homework, electronic product usage and outdoor activities as dependent variables in a multivariate Logistic regression analysis, the results showed that children and adolescents with an average outdoor activity duration for ≥2 h on weekends had a lower risk of myopia ( OR =0.86, P < 0.01).
Conclusions
The level of outdoor activity among children and adolescents on weekends needs to be improved. Outdoor activities on weekends is an associated factor for myopia among children and adolescents. Particularly, girls, those with myopic parents, schools from urban districts, and spending long hours on homework during weekends among children and adolescents require increased attention.

Chinese Journal of School Health 2025;46(1):24-28
Objective:
To investigate the visual acuity and correction conditions of children and adolescents in Shanghai, so as to provide a scientific basis for developing intervention measures to prevent myopia and protect vision among children and adolescents.
Methods:
From October to December 2022, a stratified cluster random sampling survey was conducted, involving 47 034 students from 16 municipal districts in Shanghai, covering kindergartens (≥5 years), primary schools, middle schools, general high schools and vocational high schools. According to the Guidelines for Screening Refractive Errors in Primary and Secondary School Students, the Standard Logarithmic Visual acuity Chart was used to examine naked vision and corrected vision of students, and general information was collected. The distribution and severity of visual impairment in different age groups were analyzed, and χ 2 tests and multivariate Logistic regression were used to explore factors associated with visual impairment.
Results:
The detection rate of visual impairment among children and adolescents was 76.2%, with a higher rate among females (78.8%) than males ( 73.8 %), higher among Han ethic students ( 76.2 %) than minority students (71.2%), and higher among urban students (76.7%) than suburban students (75.8%), all with statistically significant differences ( χ 2=162.6, 10.4, 5.5, P <0.05). The rate of visual impairment initially decreased and then increased with age, reaching its lowest at age 7 (53.8%) and peaking at age 17 (89.6%) ( χ 2 trend = 3 467.0 , P <0.05). Severe visual impairment accounted for the majority, at 56.6%, and there was a positive correlation between the severity of visual impairment and age among children and adolescents ( r =0.45, P <0.05). Multivariate Logistic regression showed that age, BMI, gender, ethnicity and urban suburban status were associated with visual impairment ( OR =1.18, 1.01, 1.38 , 0.79, 0.88, P <0.05). Among those with moderate to severe visual impairment, the rate of spectacle lens usage was 62.8%, yet only 44.8 % of those who used spectacle lens had fully corrected visual acuity. Females (64.9%) had higher spectacle lens usage rates than males (60.6%), and general high school students had the highest spectacle lens usage (83.9%), and there were statistically significant differences in gender and academic stages ( χ 2=57.7, 4 592.8, P <0.05).
Conclusions
The rate of spectacle lens usage among students with moderate to severe visual impairment is relatively low, and even after using spectacle lens, some students still do not achieve adequate corrected visual acuity. Efforts should focus on enhancing public awareness of eye health and refractive correction and improving the accessibility of related health services.

ObjectiveTo explore the possible mechanism of action of Bushen Huoxue Granules (补肾活血颗粒, BHG) in the treatment of Parkinson's disease (PD) through the Nrf2/NLRP3 inflammasome axis. MethodsA total of 84 male C57/BL 6 mice were randomly divided into blank group, model group, Madopar group, dimethyl fumarate group, and low-, medium, and high-dose BHG group, with 12 mice in each group. Except for the blank group, all groups were induced into PD models by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) at a concentration of 30 mg/ml for 7 consecutive days. The blank group received an equal volume of saline. After model establishment, the low-, medium, and high-dose BHG groups were treated with 1.5, 3, and 6 g/(kg·d) of the BHG by gavage, respectively. The Madopar group was given 0.113 g/(kg·d) of Madopar tablets by gavage, and the dimethyl fumarate group was given 50 mg/(kg·d) of dimethyl fumarate solution. The blank group and the model group were given 10 ml/(kg·d) of distilled water by gavage. Gavage was administered once daily for 14 days. Behavioral changes were evaluated using the open field test (total distance, central area distance, and average speed), rotarod test (time on the rod), and climbing pole test (climbing time). Serum levels of interleukin-1β (IL-1β), interleukin-18 (IL-18), and myeloperoxidase (MPO) were measured by ELISA. Immunohistochemistry was used to detect tyrosine hydroxylase (TH) expression in the brain substantia nigra. Immunofluorescence was used to detect α-synuclein (α-syn) expression. Western Blot was used to detect Nrf2, NLRP3, Caspase-1, and α-syn protein levels in the brain substantia nigra. RT-PCR was used to detect mRNA expression levels of Nrf2, NLRP3, and Caspase-1 in the brain substantia nigra. ResultsCompared with the blank group, the model group showed decreased total distance, central area distance, and average speed, reduced time on the rotarod, prolonged climbing time, reduced TH expression, increased α-syn expression, decreased Nrf2 protein and mRNA expression, increased NLRP3 and Caspase-1 protein and mRNA expression, and elevated serum IL-1β, IL-18, and MPO levels (P<0.05). Compared with the model group, all drug interventions significantly improved the above indicators (P<0.05). There was no significant differences in all indicators between the high-dose BHG group and the Madopar group (P>0.05). Compared with the dimethyl fumarate group, the medium and high-dose BHG groups showed increased Nrf2 mRNA expression in the brain substantia nigra (P<0.05). Compared with the high-dose BHG group, the low-dose group showed decreased total distance, central area distance, and average speed, reduced serum IL-18 levels, decreased α-syn, Nrf2, NLRP3, and Caspase-1 protein levels, and lower Nrf2 mRNA expression (P<0.05). ConclusionThe mechanism by which BHG treat PD may involve activating the Nrf2/NLRP3 inflammasome axis in the brain substantia nigra, thereby reducing neuroinflammation and α-syn aggregation. The high-dose group showed the best effects.

ObjectiveTo systematically analyze the global policy framework, standard systems and application technology models of digital rehabilitation within the framework of the World Health Organization (WHO) Global Digital Health Strategy and propose policy recommendations for the future development of digital rehabilitation. MethodsBased on the policies on digital health and rehabilitation development issued by the WHO, focusing on the Global Digital Health Strategy, Rehabilitation 2030 Initiative, Rehabilitation in Health Systems, Rehabilitation in Health Systems: A Guide for Action, and World Report on Disability, a systematic review was conducted, to explore the policy architecture and core content of digital rehabilitation, the standard system for digitalizing rehabilitation, and key technological models for the development of digital rehabilitation. ResultsIn the context of global health and digital transformation, the development of digital rehabilitation services was an essential component of the global digital health strategy. Building a comprehensive policy framework and content system for digital rehabilitation was critical for strengthening rehabilitation data governance, enhancing data utilization efficiency, and ensuring data privacy and security. Empowering rehabilitation with digital technology was vital for improving the standardization, effectiveness, coverage, quality and safety of rehabilitation services. International digital rehabilitation policies primarily involved the following areas: policy and governance, digital standard systems, data privacy, security and ethics, digital talent cultivation and capacity building, and monitoring, evaluation and continuous improvement of digitally empowered rehabilitation services. The standard system for rehabilitation digitization covered the three major reference classifications of the WHO Family of International Classifications, including International Classification of Diseases Eleventh Revision (ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI), especially ICF. It also included international data interoperability standards, data security and privacy protection standards, data quality and certification standards, and health information standards, etc. The application technology models of digital rehabilitation primarily included data-driven service models, artificial intelligence -enabled models, and remote rehabilitation models combined with virtual reality, augmented reality technologies, and Internet of Things support. ConclusionThe establishment and implementation of comprehensive policies, standards and technological models for digital rehabilitation are crucial for driving the digital transformation and development of global rehabilitation services. Under the framework of the WHO Global Digital Health Strategy, it is necessary to build adaptive digital rehabilitation policy frameworks, and enhance digital governance capabilities and levels, establishing and improving digital rehabilitation standard systems, and promoting the interoperability and integration of rehabilitation data with other health big data. Meanwhile, it is essential to actively develop data-driven technological models for rehabilitation services to comprehensively improve the accessibility, availability, quality and safety of rehabilitation services.
