2.Association of outdoor activity level and myopia among children and adolescents in Shanghai
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.

OBJECTIVE To study the improvement effects and potential mechanisms of water extract from Chrysanthemum morifolium on skeletal muscle atrophy in rats after ischemic stroke. METHODS Sprague-Dawley rats were randomly divided into sham operation group, model group, ATP group (10 mg/kg), C. morifolium water extract high-dose and low-dose groups (1.08, 0.54 g/kg). Except for sham operation group, ischemic stroke models were induced in rats from the other groups using middle cerebral artery occlusion. Starting from the first day after surgery, rats in each group were given corresponding drug/normal saline intragastrically, once a day, for consecutive 7 days. On the 7th day post-surgery, the rats’ body weights were measured, and their motor functions were evaluated, including Longa scores, exercise distance, grip strength; the electrophysiological signals of the skeletal muscles in rats were measured; the pathological morphology of the soleus muscle in rats was observed; the levels of tumor necrosis factor-α (TNF-α) in serum and soleus muscle were measured; the expressions of proteins related to TNF-α/c-Jun N- terminal kinase (JNK)/mitogen-activated protein kinase (MAPK) signaling pathway in the soleus muscle were determined. RESULTS Compared with sham operation group, the body weight, grip strength and exercise distance of rats were decreased/ shortened significantly (P<0.01); additionally, there was a notable reduction in the interpeak value of skeletal muscle electrophysiology (P<0.05 or P<0.01). Longa score, as well as the levels of TNF-α in serum and soleus muscle, and the expression levels of TNF-α, phosphorylated JNK, phosphorylated MAPK, muscle ring-finger protein-1, and muscle atrophy Fbox- 1 protein in the soleus muscle, were all significantly elevated (P<0.01). The skeletal muscle cells of the soleus muscle in the model group showed significant atrophy, with a markedly decreased cross-sectional area (P<0.01). Compared with the model group, the levels of the aforementioned indicators were significantly reversed in C. morifolium water extract groups (P<0.05 or P< 0.01), and the skeletal muscle cells of the soleus muscle were markedly enlarged. CONCLUSIONS C. morifolium water extract can improve skeletal muscle atrophy in rats after ischemic stroke, the mechanism of which may be associated with suppressing the activation of the TNF- α/JNK/MAPK E-mail:19932015@cdutcm.edu.cn signaling pathway.

[Objective] To analyze the prognostic value of prostate cancer (PCa) pyroptosis-related genes (PRGs) using gene expression databases and to explore the regulatory mechanism of nucleotidebinding oligomerization domain-like receptor containing pyrin domain 1 (NLRP1) in the pyroptosis of PCa cells. [Methods] Fragments per kilobase of exon model per million reads mapped (FPKM) data and clinical information from PCa and adjacent tissues from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) were obtained. Differentially expressed PRGs between PCa and adjacent tissues, classified subtypes and plotted survival curves were analyzed. Univariate Cox regression analysis, least absolute shrinkage and selection operator (LASSO) regression analysis were conducted to screen prognosis-related PRGs, risk scores were calculated, and a prognostic risk model was constructed and validated. Patients were divided into high and low risk groups based on the median risk scores from the training and validation sets, and gene ontology (GO) enrichment and kyoto encyclopedia of genes and genomes (KEGG) analysis were conducted on differentially expressed PRGs. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of NLRP1 in PCa cell lines, and pyroptosis was induced in DU145 and LNCaP cells while morphological changes were observed. Western blot (WB) was performed to detect the expression of pyroptosis-related molecules. [Results] A total of 6 prognostic-related PRGs were obtained, including CHMP4C, CYCS, GPX4, GSDMB, NLRP1, and PLCG1. The risk score was positively correlated with the risk of recurrence but negatively correlated with the progression-free survival (P<0.001). The area under the receiver operating characteristic curves (AUCs) for the training set at 1, 3, and 5 years were 0.769 (95%CI: 0.652-0.878), 0.804 (95%CI: 0.736-0.882), and 0.772 (95%CI: 0.631-0.905), respectively, while those for the validation set were 0.731 (95%CI: 0.647-0.826), 0.753 (95%CI: 0.674-0.818), and 0.763 (95%CI: 0.626-0.849), respectively. Differences in expression levels of the 6 PRGs were observed between the high and low risk groups in both the training and validation sets (P<0.05). Cox regression analysis showed that T stage, prostate specific antigen (PSA), Gleason grade, and risk score were independent predictors of PCa prognosis (P<0.05). Differences in risk scores were observed among patients of different ages, T stages, and Gleason grades (P<0.05). NLRP1 was found to be lowly expressed in PCa cell lines and was involved in the regulation of pyroptosis in DU145 and LNCaP cells. [Conclusion] The prognostic risk model constructed based on PRGs has a certain predictability for the prognosis of PCa patients, and NLRP1 may be involved in the regulation of pyroptosis in PCa cells.

Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels, but their effectiveness is limited. The mechanisms underlying its onset are complex, and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression, involving multiple pathways, including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 (TLR4/NLRP3), nuclear factor-κB (NF-κB), Janus kinase/signal transducer and activator of transcription (JAK/STAT), mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK), brain-derived neurotrophic factor/tyrosine kinase receptor B (BDNF/TrkB), cyclic AMP/protein kinase A/cAMP response element-binding protein (cAMP/PKA/CREB), and others. Traditional Chinese medicine(TCM) is based on a holistic approach and the principle of treatment based on the differentiation of syndromes, regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems, involving liver Qi stagnation, heart spirit deficiency, kidney essence depletion, and spleen dysfunction. TCM compound treatments focus on soothing the liver, strengthening the spleen, calming the heart, and replenishing essence, with formulas such as Xiaoyaosan, Zishui Qinggan Yin, and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi, such as salidroside, ginsenoside Rb1, astragaloside, and muscone. External TCM treatments, primarily acupuncture, aim to open the orifices and invigorate the spirit. Acupoints such as Baihui, Shenting, and Yintang are commonly used. Additionally, massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression, aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.

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.

Journal of Prevention and Treatment for Stomatological Diseases 2025;33(1):41-49
Objective :
To explore the changes of periodontal soft and hard tissue parameters of the maxillary central incisors after the distant migration of the maxillary total dentition in adult patients with different periodontal phenotypes, so as to provide a reference for orthodontic treatment.
Methods:
The study was approved by the hospital ethics committee, and the patients signed the informed consent form. Fifty-two adult patients in the orthodontic department of Hefei Stomatological Hospital were selected and divided into thick gingival and thin gingival groups, with 26 cases in each group. The labial and palatal alveolar bone parameters and various periodontal indexes of the maxillary central incisor teeth of the two groups were collected and recorded before and after treatment. SPSS 26.0 statistical software was used to statistically analyze the intra-group and inter-group differences.
Results:
After orthodontic treatment, the differences in sella-nasion-subspinale angle (SNA), sella-nasion-supramental angle (SNB), and subspinale-nasion-supramental angle (ANB) were not statistically significant (P > 0.05). However, the inclination of the upper middle incisor teeth (U1-NA) decreased significantly (P < 0.05), and there was no significant difference in SNA, SNB, ANB, and U1-NA between the two groups after treatment (P > 0.05). The thickness of the labial alveolar bone of the maxillary central incisors in both groups increased at the labial neck 1/3 and labial middle 1/3 (P < 0.05), and decreased at the apical 1/3 (P < 0.05). The thickness of the palatal alveolar bone decreased at the labial neck 1/3 and labial middle 1/3 (P < 0.01), and increased at the apical 1/3 (P < 0.01). In both groups, the height of the lip and palate of the upper jaw decreased to different degrees, and the height of the palatal alveolar bone was lower in the thin gingival group (P < 0.05). There were no significant differences in maxillary central incisor probing depth (PD), lip keratinized tissue width (KTW), or lip gingival recession (GR) between the two groups after treatment (P > 0.05).
Conclusion
In the process of maxillary central incisor adduction, the labial-palatine alveolar bone remodeling is not uniform, and the alveolar bone of palatine side is mainly absorbed, which should be paid attention to clinically. Palatal alveolar bone height decreased more significantly in patients with thin gingiva after orthodontic treatment, and the risk of bone fenestration and bone dehiscence was greater.

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.

OBJECTIVE To study the effects of Sanchong tongluo sanjie formula on the proliferation and apoptosis of Lewis lung cancer cells. METHODS The rats were given Sanchong tongluo sanjie formula powder [0.946 g/(kg·d)], Sanchong tongluo sanjie formula decoction [2.730 g/(kg·d)], and normal saline intragastrically, and injected with Cisplatin injection (4.2 mg/kg) intra-peritoneally to prepare powder-containing serum, decoction-containing serum, positive control serum and negative control serum. Lewis lung cancer cells were divided into negative control serum group, positive control serum group, and 5%, 10%, 20% drug-containing serum groups. The cell proliferation inhibition rates at 24, 48, and 72 hours post- intervention were measured to screen the optimal intervention concentrations of powder-containing serum and decoction-containing serum. The cell invasion ability, metastasis ability and apoptotic rate were detected in the negative control serum group, positive control serum group, 20% powder-containing serum group, and 20% decoction-containing serum group. Protein expressions of vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1α (HIF-1α), prolyl hydroxylase-2 (PHD2), matrix metalloproteinase-2 (MMP-2), extracellular regulated protein kinases (ERK),c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38 MAPK) were detected. RESULTS The cell proliferation inhibition rates for both the 20% powder-containing serum group and the 20% decoction-containing serum group, when intervened for 48 hours, were not less than 50%. Compared with negative control serum group, the number of invasive Lewis lung cancer cells and migration distance were decreased significantly, while the apoptotic rate was increased significantly (P<0.05); the apoptotic rate in the 20% powder- containing serum group was significantly higher than 20% decoction-containing serum group (P<0.05). The protein expressions of PHD2 and p38 MAPK were increased significantly in the 20% powder-containing serum group (P<0.05), while the protein expression of HIF-1α was decreased significantly in the 20% decoction-containing serum group (P<0.05). CONCLUSIONS Sanchong tongluo sanjie formula can inhibit the proliferation, invasion and metastasis of Lewis lung cancer cells while promoting their apoptosis. The mechanism of action may be related to regulating the PHD2/HIF-1α signaling pathway. Furthermore, the powder demonstrates superior efficacy compared to the decoction, suggesting that they may possess different mechanisms of action.
