To address the constrains imposed by insufficient hydrogen peroxide (H2O2) and high glutathione (GSH) expression in tumor cells on the efficacy of chemodynamic therapy (CDT), zeolitic imidazolate framework-8 (ZIF-8) loaded with disulfiram (DSF) and 3-amino-1,2,4-triazole (3-AT) was synthesized via a one-pot approach. Subsequently, hyaluronic acid (HA)-modified cupric peroxide (CuO2) was in-situ grown on its surface through biomineralization to construct a multifunctional copper-based nanozyme ADZCH (3-AT/DSF@ZIF-8@CuO2-HA). This nanoplatform disrupts the intratumoral H2O2 homeostasis, depletes GSH, and synchronously delivers DSF and Cu2+ via cascade catalysis, thereby enhancing CDT and sensitizing tumors to DSF-based chemotherapy. The results of physicochemical characterization indicated that ADZCH presented a uniform core-shell structure with favorable dispersibility. Its particle size and Zeta potential were 196.5 nm and −19.5 mV, respectively. It possessed a microporous structure with a specific surface area of 81.8600 m2/g, and demonstrated efficient loading capacity for DSF and 3-AT, achieving drug loading efficiencies of 5.91% and 45.07%, respectively. Moreover, ADZCH can continuously and slowly release drugs in an acidic environment and maintain good stability under diverse physiological conditions. In vitro functional assays verified that ADZCH catalytically generated H2O2 and hydroxyl radicals while concurrently depleting GSH in a concentration- and incubation time-dependent manner. Cellular uptake experiments showed that HA modification significantly improved the uptake of nanoparticles by 4T1 cells. Cytotoxicity tests showed that 80 μg/mL ADZCH had a significant cytotoxic effect on 4T1 cells but no significant toxicity on L929 cells. DCFH-DA probe detection indicated that ADZCH could significantly induce intracellular reactive oxygen species (ROS) generation, thereby enhancing CDT efficacy. Live/dead staining experiments showed that ADZCH efficiently induced apoptosis, with the proportion of dead cells reaching 94.74%, demonstrating its promising potential for anti-tumor applications.This study provides new research ideas and experimental basis for overcoming the tumor microenvironment barrier and enhancing the anti-tumor effect of CDT combined with chemotherapy.

ObjectiveTo identify and validate the optimal compatibility dosage of astragaloside Ⅰ (ASⅠ) and calycosin (CY) in the treatment of cholestatic liver fibrosis. MethodsA 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet was used to establish a mouse model of liver fibrosis, and the uniform design method was used to identify the optimal combination ratio of the saponin component ASⅠ and the flavonoid component CY in Astragalus membranaceus. In the uniform design experiment, 80 male C57/BL6J mice were divided into normal group, model group, total astragalosides (TAS) group, groups A — F with a uniform design, and obeticholic acid (OCA) group using a random number table, with 8 mice in each group. The multiple regression analysis was used to establish the optimal regression equation and obtain the potential optimal combination ratio. The in vivo efficacy of the empirically optimal combination identified in the uniform design and the optimal dose combination predicted by the regression equation were compared for validation. A one-way analysis of variance was used for comparison of continuous data between multiple groups; the Levene test was used to determine the homogeneity of variance, and the least significant difference t-test was used for comparison of data with homogeneity of variance between two groups, while the Dunnett T3 test was used for comparison of data with heterogeneity of variance. ResultsIn the uniform design regimen, the JYB combination (3.125 mg/kg ASI+50 mg/kg CY) significantly reduced the serum levels of alanine aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bile acid (TBA), total bilirubin (TBil), and indirect bilirubin (IBil) in mice with DDC-induced cholestatic liver fibrosis (all P<0.05), and it also reduced hepatic Hyp content (P<0.01), semi-quantified collagen deposition area (P<0.001), and the mRNA expression levels of Acta2, Col1a1, Ck7, Ck19, Adgre1, TLR4, TNF-α, and CCL5 in liver tissue (all P<0.05). The regression equation showed that 50 mg/kg ASⅠ+50 mg/kg CY was the potential optimal combination, which was named as P1 combination. However, subsequent validation experiments showed that P1 combination only significantly improved the serum levels of AST and IBil and hepatic Hyp content in DDC mice (all P<0.05), with no significant impact on hepatic collagen deposition and the mRNA expression levels of Acta2, Ck7, Ck19, Adgre1, and CCL5 (all P>0.05). In contrast, the JYB combination significantly improved the serum levels of ALP, ALT, AST, TBA, TBil, and IBil, hepatic collagen deposition, hepatic Hyp content, and the mRNA expression levels of Acta2, Col1a1, Ck7, Ck19, Adgre1, TLR4, TNF-α, and CCL5 (all P<0.05). ConclusionThis study shows that the JYB combination (3.125 mg/kg ASⅠ+50 mg/kg CY) can significantly alleviate DDC-induced liver fibrosis, with comparable efficacy to total saponins from Astragalus membranaceus, and compared with ASⅠ or CY administered alone, the JYB combination has a significantly better regulatory effect on the serum levels of ALP and TBA.

Temporomandibular disorders (TMD) encompass a prevalent group of conditions affecting the masticatory muscles, temporomandibular joint, and associated structures. Currently, it is widely recognized by scholars both domestically and internationally that TMD has a complex etiology and pathogenesis. Most patients present clinically with pain, yet effective treatment options remain limited. In recent years, the role of ion channels in the pathological mechanisms and therapeutic approaches for TMD has garnered increasing attention. This review systematically summarizes the function of ion channels in the management of temporomandibular joint diseases. First, the multifaceted roles of ion channels in treating TMD are examined, including their regulatory effects on TMJ muscle dysfunction, joint structural abnormalities, and TMJ-related pain. Finally, the potential value of ion channel research in TMD therapy is discussed. With advancing research in this field, ion channel-targeted therapies for temporomandibular disorders are expected to achieve new breakthroughs, thereby providing an important theoretical foundation and practical guidance for developing novel clinical treatment strategies.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics ( 2026 edition ) in response to the challenges faced by such clinics in China, including uneven development, large discrepancies in service specifications, insufficient patient awareness, and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association, the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association, and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association, a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research, current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections: definition and connotation of pharmacist-managed clinics, establishment requirements, implementation and management, post competency, and practical research. Firstly, the definition and connotation included three operational forms of pharmacist-managed clinics (independent mode, physician-pharmacist joint mode, and online pharmacist-managed clinic mode) and classified service modes (specialty-specific, drug-specific, and disease-specific pharmacist-managed clinics). The establishment requirements were further refined, covering system construction (pharmaceutical service management system, quality control and assessment mechanism), personnel qualifications (professional credentials, continuing education and professional training, etc), service recipients, as well as service venues and facilities. Subsequently, the implementation and management of pharmacist-managed clinics were proposed, involving service procedures, intervention measures, documentation and records, patient education and follow-up, humanistic care, as well as risk management and quality control. Finally, post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics, as well as the suggestions on teaching methods; practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment, management, teaching, and research, fill the guideline gap in this field, and can promote the high-quality development of pharmacist-managed clinics.

Objective To investigate the sleep status in children with autism spectrum disorder (ASD) and its relationship with executive function and neurodevelopment. Methods The medical records of 346 children with ASD in the hospital from April 2023 to January 2025 were retrospectively collected. The sleep status of children was investigated by Children’ s Sleep Habits Questionnaire (CSHQ). According to the score, the children were divided into good sleep group (CSHQ score<41 points, 189 cases) and sleep disorder group (CSHQ score≥41 points, 157 cases). The general data were compared between groups of children. Chinese version of Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) and developmental behavior assessment scale of children aged 0-6 years (Children's psychological scale-II) were used to analyze the relationship between sleep status and executive function and neurodevelopment in children with ASD. Results The CSHQ score of 346 children was (39.08±3.24) points, including 157 cases with CSHQ score≥41 points and 189 cases with CSHQ score<41 points. The proportion of severe previous medical history and executive function score in sleep disorder group were significantly higher than those in good sleep group, and the evaluation result of developmental quotient was lower than that in good sleep group (P<0.05). Logistic regression analysis showed that executive ability and neurodevelopment were closely related to sleep status in children with ASD (P<0.05). Spearman correlation analysis showed that sleep status in children with ASD was negatively correlated with executive function (r=-0.456, P<0.05), and was positively correlated with the developmental quotient (r=0.547, P<0.05). Conclusion The incidence rate of sleep disorder is high in children with ASD, and sleep status is closely related to executive function and neurodevelopment. Clinically, it is necessary to pay attention to the sleep problems in children with ASD, and take effective intervention measures to improve the sleep quality of children and promote the training of executive function and neurodevelopment.

Chinese Journal of School Health 2026;47(2):168-172
Objective:
To evaluate the current situation of thermal environment in primary and secondary school classrooms during winter, and to analyze students thermal comfort needs, so as to provide a basis for improving classroom thermal environment.
Methods:
From December 16 to 26, 2024, a stratified cluster random sampling method was used to select 90 classrooms from 15 primary and secondary schools in centralized/air conditioned heating areas(Liaoning Province, Tianjin City, Shanghai City) and naturally ventilated areas(Anhui Province and Jiangxi Province)for on site environmental measurement. A questionnaire survey was conducted among 743 students. The differences between groups using the χ 2 test were compared. Based on actual measurement data, a predicted mean vote prepared percentage of dissatisfied (PMV-PPD) model for centralized/air conditioned classrooms and an adaptive model for naturally ventilated classrooms were established, and the thermal neutral temperature and comfort interval were calculated.
Results:
The average outdoor temperature during on site measurement was 4.00(0.20,7.00)℃. In classrooms with centralized or air conditioned heating systems, the measured average temperature was (19.33±2.59)℃, with a thermal comfort range of 20.35-25.35 ℃ and a thermal neutral temperature of 22.85 ℃. And 13.92% of students reported feeling cold, while 80.80% felt comfortable. In classrooms with natural ventilation, the measured average temperature was (12.26±1.83)℃, with a thermal neutral temperature of 19.67 ℃ and a thermal comfort range of 16.17-23.17 ℃. About 48.33% of students reported feeling cold, and 49.81 % felt comfortable.The results of univariate analysis showed that there were statistically significant differences in shoe thickness, temperature sensation, relative humidity sensation and wind speed sensation between centralized/air conditioned heating areas ( χ 2= 7.01 , 31.47, 13.57, 13.80,all P <0.05). There were also statistically significant differences in school stage for primary and secondary school students, body mass index, classroom location for seat, temperature sensation, relative humidity sensation and wind speed sensation between naturally ventilated areas ( χ 2=42.13, 11.13, 11.04, 60.39, 29.27, 38.46,all P <0.05).
Conclusions
There are differences in thermal environment and students subjective thermal comfort in primary and secondary schools under different ventilation modes in winter. The temperature standards for heated classrooms should be revised, and differentiated environmental regulation strategies should be adopted based on different ventilation methods to improve students health and comfort levels.

Objective:
To investigate the prevalence of depressive symptoms and their associated factors among students in Zhejiang Province, so as to provide evidence for targeted prevention strategies.
Methods:
A stratified cluster random sampling method was used to select 23 829 college students and primary and secondary school students aged 11-22 years in Zhejiang Province from December 2019 to February 2020. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Three machine learning algorithms, including Logistic regression, random forest, and eXtreme Gradient Boosting (XGBoost), were applied to construct predictive models, and key associated factors were identified by comparing model performance.
Results:
The detection rate of depressive symptoms among students in Zhejiang Province was 19.92%; the rates were 17.20% in boys and 22.87% in girls( χ 2=164.89, P <0.05). The CES-D total score was 9.00(4.00,13.00). Multiple Logistic regression analysis revealed that loneliness had the strongest association with depressive symptoms ( AOR =9.58, 95% CI =8.90-10.30), while bullying exposure ( AOR =4.39, 95% CI =4.02-4.80), female students( AOR =1.81, 95% CI =1.68-1.94),never eating breakfast ( AOR = 2.34,95% CI =2.00-2.67) and overweight/obesity( AOR =1.10,95% CI =1.08-1.12) were significant associated factors of depressive symptoms among students (all P <0.05). Analysis based on the XGBoost model produced highly consistent results, identifying the above 5 factors as the core features with the highest correlation strength (all P <0.05).
Conclusions
Female, loneliness, bullying exposure, frequency of weekly breakfast and BMI are strongly associated with depressive symptoms among students. Mental health education for high risk groups should be strengthened, and coordinated prevention efforts between families and schools are recommended.

ObjectiveTo construct a scale for the diagnosis of chronic atrophic gastritis (CAG) with turbid toxin accumulating in the stomach. MethodsFirst, a research group was established to construct the scale framework. Relevant literature of CAG with syndrome of turbid toxin accumulating in the stomach was searched in CNKI, Wanfang Database (WF), and VIP Database (CQVIP) from April 1, 2003 to April 1, 2023, and items were preliminarily selected after standardization of terms. Through clinical investigation, the discrete trend method, correlation coefficient method, Cronbach's coefficient method, and factor analysis method were used to screen symptom items, and the frequency method was used to screen signs, tongue coating, and pulse conditions. Three rounds of Delphi expert consultation were conducted to determine the items of the scale. The weight of each item was obtained by the analytic hierarchy process. ResultsA total of 49 articles were included, and 45 items were obtained after primary screening, including 28 symptoms, 2 signs, 10 tongue coatings, and 5 pulse conditions. After clinical investigation, 15 symptoms were retained, and 8 signs and pulse conditions of tongue coating were retained. The positive coefficients of experts in three rounds of Delphi expert consultation were 100%, 96.67%, and 100%, respectively. The expert authority coefficients were 0.86, 0.87, and 0.87, respectively, and the coordination coefficients were 0.18, 0.25, and 0.30. After core group discussion, Delphi method investigation, and AHP weight assignment, the diagnostic scale items of CAG with turbid toxin accumulating in stomach syndrome were finally established, namely, dark red or purplish tongue proper with yellow greasy (or dry) coating (30 points), epigastric stuffiness and fullness or pain (15 points), sticky and unsmooth defecation (10 points), taste disturbance (sticky mouth, fetid breath, bitter taste, 7 points), heartburn or acid regurgitation (6 points), dizziness and clouding (5 points), general heaviness and fatigue (5 points), slippery, string‑slippery, or slippery‑rapid pulse (5 points), dysuria (or yellow or deep yellow urine, 4 points), poor appetite (4 points), dull complexion (3 points), sticky, greasy, and fetid secretions (3 points), and poor sleep (3 points). ConclusionBased on the establishment, screening, confirmation, and weighting of an item pool, combined with subjective and objective approaches as well as qualitative and quantitative methods, a diagnostic scale for CAG with the syndrome of turbid toxin accumulating in the stomach was successfully constructed.

ObjectiveTo explore the visual attention distribution across different lateral facial profiles and analyze the influence of observer gender and professional background on aesthetic evaluation, providing an aesthetic basis for the design of clinical orthodontic treatment. MethodsEye-tracking technology was employed to record the gaze paths of 136 subjects (orthodontists, non-orthodontic dentists, and non-medical professionals) when evaluating three types of male and female lateral profiles (convex, straight, and concave). A questionnaire survey was conducted using a visual analog scale (VAS). Data differences and the consistency between eye-tracking and questionnaire results were analyzed through t-tests, analysis of variance (ANOVA), and Kappa coefficient analysis. ResultsThe questionnaire scores for straight profiles were significantly higher than those for convex and concave profiles (P<0.05). Eye-tracking revealed that subjects primarily focused on the eye and nasal regions (P<0.001), followed by the mouth. However, orthodontists showed no significant difference in attention between the mouth and eye-nasal areas (P>0.05). Additionally, gender differences were notable. Female observers prioritized the mouth (P<0.05), while male observers paid later attention to the oral-buccal region. The forehead and chin rapidly attracted attention during the initial evaluation phase, particularly in female concave profiles (P<0.05). Eye-tracking data demonstrated high consistency with questionnaire results (κ=0.868). ConclusionThis study, utilizing eye-tracking technology, finds that the eye and nasal regions are the core focus areas for aesthetic evaluation of lateral profiles. Gender differences result in distinct gaze preferences (males emphasize the nose, while females emphasize the eyes), whereas orthodontists focus more on the lips and forehead. As aesthetic baselines, the forehead and chin, with their profile characteristics, should be prioritized in treatment. This research provides a basis for developing personalized orthodontic plans and establishing aesthetic consensus between clinicians and patients.

ObjectiveTo investigate the effects of atorvastatin (ATV) on the proliferation and differentiation of rat bone marrow mesenchymal stem cells (BMSCs), periodontal ligament stem cells (PDLSCs), and dental pulp stem cells (DPSCs) in vitro, and to validate the regulatory effect of ATV on periodontal bone formation and tooth movement using a rat orthodontic tooth movement (OTM) model. MethodsThe effects of ATV on the proliferation and osteogenic/odontogenic differentiation of rat BMSCs, PDLSCs, and DPSCs were assessed in vitro. CCK-8 assay was used to detect the proliferation of the three types of cells. Alkaline phosphatase (ALP) staining and Alizarin Red staining were employed to evaluate osteogenic differentiation capacity. Western blot was used to detect the expression of osteogenesis-related proteins [collagen type I (COL-I), Runt-related transcription factor 2 (Runx2), bone morphogenetic protein-2 (BMP-2), osteocalcin (OCN)] and the odontogenesis-related protein dentin sialophosphoprotein (DSPP) in BMSCs, PDLSCs and DPSCs. An OTM rat model was established, with rats randomly assigned to an ATV gavage group and a control group. The ATV gavage group received daily oral administration of ATV at a dose of 20 mg/kg, while the control group received an equal volume of solvent by gavage. Tooth movement distance was measured via Micro-CT on days 7, 14, and 21. Histomorphology of periodontal tissues was observed using Hematoxylin and Eosin (HE) staining and Masson staining. The gene and protein expression levels of osteogenic markers (BMP-2, Runx2, OCN) on the tension side of the first molar were detected by qRT-PCR and immunohistochemistry, respectively. ResultsATV at concentrations of 1×10⁻⁶ mol/L and 1×10⁻⁷ mol/L significantly promoted the proliferation and osteogenic/odontogenic differentiation of BMSCs, PDLSCs, and DPSCs, manifested as enhanced ALP activity, increased mineralized nodule formation, and up-regulated expression of osteogenic/odontogenic proteins COL-I, Runx2, BMP-2, OCN, and DSPP (P<0.001). In the OTM model, compared with the control group, the ATV gavage group showed a significant reduction in tooth movement distance (P<0.05), enhanced osteogenic activity in periodontal tissues, and significantly increased gene (P<0.001) and protein (P<0.05) expression of BMP-2, Runx2, and OCN on the tension side of the first molar. ConclusionATV enhances periodontal osteogenesis by promoting osteogenic/dentinogenic differentiation, thus inhibiting tooth movement.
