OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction (BYHWD) and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation, as well as 30% ethanol, 50% ethanol, and 75% ethanol fractions (namely, the CC effective fraction, 30YC effective fraction, 50YC effective fraction, and 75YC effective fraction), were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum (blank serum and simvastatin-containing serum were prepared using the same protocol). Human L02 hepatocytes were divided into control group, model group, simvastatin-containing serum group, BYHWD-containing serum group, CC-containing serum group, 30YC-containing serum group, 50YC-containing serum group, and 75YC-containing serum group. Except for the control group, other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model, and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed, and the proportion of lipid droplet area was calculated; the levels of triglycerides (TG) and indicators of oxidative stress [malondialdehyde (MDA), superoxide dismutase (SOD)] as well as liver function [alanine amino- transferase (ALT), aspartate amino-transferase (AST)] in cells were detected; protein and mRNA expressions of AMP-activated protein kinase (AMPK)/sterol regulatory element-binding protein-1 (SREBP-1)/glycerol-3-phosphate acyltransferase (GPAT) signaling pathway were also measured. RESULTS Compared with the control group, cells in the model group exhibited severe cellular steatosis, with a significantly increased proportion of lipid droplet area, as well as the elevated levels of TG, ALT, AST, and MDA in cells, along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT (P<0.05). The level of SOD, mRNA expression of AMPK, as well as the protein phosphorylation level of AMPK were decreased significantly (P<0.05). Compared with the model group, cellular steatosis was alleviated in all drug-containing serum groups, and the levels of most of the aforementioned quantitative indicators were significantly reversed (P<0.05). CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway, inhibiting oxidative stress responses, and reducing lipid deposition.

Attention deficit and hyperactive disorder (ADHD) is the most common neurodevelopmental disorder of childhood. It seriously impairs academic achievement, social interaction, and vocational development, and increases the risk of accidental injury and substance abuse. In some cases, the symptoms may also exert an indirect disruptive effect on public order. Its aetiology involves interactions among genetic, perinatal environmental, and psychosocial factors that cannot be fully disentangled by single clinical studies. Therefore, a systematic evaluation of existing animal models is essential for revealing pathophysiology and developing novel therapies. Using the keywords "attention deficit and hyperactive disorder", "models, animal", "validity", and their English equivalents, we systematically searched PubMed, Web of Science, CNKI, and Wanfang for publications from 2000 to 2025 (retrieving 328 publications) and added further references by citation tracking. Eighty-six rodent ADHD models that provided detailed construction protocols, behavioural assessments, neurobiological mechanisms, or pharmacological data were included and classified into spontaneous genetic, genetically engineered, and environmentally induced paradigms. Their face, construct, and predictive validity were compared. Among spontaneous genetic models, spontaneously hypertensive rats reproduce hyperactivity, impulsivity, and stimulant responses well, yet hypertension and sex differences limit specificity. Acallosal mouse strains link corpus callosum absence to ADHD-like behaviours, but neurotransmitter studies remain scarce. Genetically engineered rodents—including dopamine transporter, neurokinin-1 receptor and mediator complex subunit 23 knockout or conditional gene knockout lines—precisely dissect dopaminergic, noradrenergic, synaptic, or epigenetic pathways, yet generally lack full phenotypic coverage, social-deficit modelling, and comorbidity representation, and are accompanied by adverse effects such as growth retardation or ocular defects. Environmentally induced models employ lead, polychlorinated biphenyls, alcohol, nicotine exposures, 6-hydroxydopamine lesions, neonatal hypoxia, early social isolation, or maternal stress to recapitulate core symptoms. However, dose-schedule standardisation is lacking. Behavioural reversibility diverges from clinical persistence, and non-specific phenotypes such as anxiety or depression are common. Overall, no single paradigm simultaneously achieves high validity across all three dimensions. Currently, ADHD models have progressed from single-factor simulations to multidimensional evaluation, yet significant gaps remain in genetic-background standardisation, sex differences, cross-species translation, and syndrome-differentiation modelling under traditional Chinese medicine. Future directions should integrate genetic, environmental, and epigenetic interactions, establish life-span validation systems, and incorporate computational neuroscience alongside integrative Chinese-Western strategies to enhance clinical relevance and translational utility, thereby providing robust evidence-based support for mechanistic elucidation, drug screening and precision intervention in ADHD.
3.Study on meal preferences of school aged children based on discrete choice experiment
Chinese Journal of School Health 2025;46(1):45-49
Objective:
To explore the relative importance of different food attributes and levels in food decision making of school aged children, and to understand their meal preferences, so as to provide the evidence for formulating precise intervention strategies for dietary behaviours of school aged children.
Methods:
From May to June 2024, a total of 854 children aged 11 to 15 years old were selected from 2 middle schools (each school in urban and rural areas) in both Hubei Province and Anhui Province by stratified cluster random sampling method to conduct a D-optimal discrete choice experiment. The mixed Logit model was used to analyze children s preference for meal attributes and different levels, and to calculate the relative importance (RI) of attributes and willingness to pay (WTP) in meal choices.
Results:
The included five food attributes had statistical significance on meal choice of school aged children ( P <0.05). The relative importance of food attributes affecting the meal choices of school aged children in descending order were dining mode ( RI =31.26%), food varieties ( RI =30.56%), cooking method( RI =23.84%), taste( RI =8.06%) and price ( RI =6.27%). Among them, school aged children preferred home cooked meals ( β =0.74) (WTP=86.3 yuan),varied foods(grain/tubers+vegetables+fish, meat, eggs and beans) ( β =0.61) (WTP=71.9 yuan), fried/roasted cooking ( β =0.51) and spicy taste ( β =0.33).Price was negatively correlated with meal choices( β =-0.01) ( P <0.05). Based on residential area and body mass index (BMI), the stratified analysis showed that dining mode was highest in the relative importance for rural children with overweight and obese children ( RI =31.28%,34.17%), both of whom preferred home cooked meals ( β =0.76, 0.91), and meals containing fish, meat, eggs and beans with grain/tubers or grain/tubers and vegetables in terms of food choice (area: β =0.53, 0.53 ; BMI: β =0.55, 0.56) ( P <0.05).
Conclusions
School aged children have different preferences for different attributes of meals. The quality of school meals should be improved,the cost of buying healthy meals should be reduced,targeted family health education should be carried out,and healthy cooking methods should be advocated.

ObjectiveTo investigate the role of 4-week high-intensity interval training (HIIT) in modulating the metabolic homeostasis of the pyruvate-lactate axis in the hippocampus of rats with chronic unpredictable mild stress (CUMS) to improve their depressive-like behavior. MethodsForty-eight SPF-grade 8-week-old male SD rats were randomly divided into 4 groups: the normal quiet group (C), the CUMS quiet group (M), the normal exercise group (HC), and the CUMS exercise group (HM). The M and HM groups received 8 weeks of CUMS modeling, while the HC and HM groups were exposed to 4 weeks of HIIT starting from the 5th week (3 min (85%-90%) Smax+1 min (50%-55%) Smax, 3-5 cycles, Smax is the maximum movement speed). A lactate analyzer was used to detect the blood lactate concentration in the quiet state of rats in the HC and HM groups at week 4 and in the 0, 2, 4, 8, 12, and 24 h after exercise, as well as in the quiet state of rats in each group at week 8. Behavioral indexes such as sucrose preference rate, number of times of uprightness and number of traversing frames in the absenteeism experiment, and other behavioral indexes were used to assess the depressive-like behavior of the rats at week 4 and week 8. The rats were anesthetized on the next day after the behavioral test in week 8, and hippocampal tissues were taken for assay. LC-MS non-targeted metabolomics, target quantification, ELISA and Western blot were used to detect the changes in metabolite content, lactate and pyruvate concentration, the content of key metabolic enzymes in the pyruvate-lactate axis, and the protein expression levels of monocarboxylate transporters (MCTs). Results4-week HIIT intervention significantly increased the sucrose preference rate, the number of uprights and the number of traversed frames in the absent field experiment in CUMS rats; non-targeted metabolomics assay found that 21 metabolites were significantly changed in group M compared to group C, and 14 and 11 differential metabolites were significantly dialed back in the HC and HM groups, respectively, after the 4-week HIIT intervention; the quantitative results of the targeting showed that, compared to group C, lactate concentration in the hippocampal tissues of M group, compared with group C, lactate concentration in hippocampal tissue was significantly reduced and pyruvate concentration was significantly increased, and 4-week HIIT intervention significantly increased the concentration of lactate and pyruvate in hippocampal tissue of HM group; the trend of changes in blood lactate concentration was consistent with the change in lactate concentration in hippocampal tissue; compared with group C, the LDHB content of group M was significantly increased, the content of PKM2 and PDH, as well as the protein expression level of MCT2 and MCT4 were significantly reduced. The 4-week HIIT intervention upregulated the PKM2 and PDH content as well as the protein expression levels of MCT2 and MCT4 in the HM group. ConclusionThe 4-week HIIT intervention upregulated blood lactate concentration and PKM2 and PDH metabolizing enzymes in hippocampal tissues of CUMS rats, and upregulated the expression of MCT2 and MCT4 transport carrier proteins to promote central lactate uptake and utilization, which regulated metabolic homeostasis of the pyruvate-lactate axis and improved depressive-like behaviors.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin (厥阴) as the closing phase" from the perspectives of time and space. In traditional Chinese medicine, jueyin governs inward, converging aspect of qi, representing the crucial turning point between the end of yin and the emergence of yang, as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly, it promotes the inward convergence and smooth descent of qi, enabling the internal retention of blood, spirit, and emotions, which nourishes the internal organs and moistens the meridian-sinews. Conversely, dysfunction of this "closing" mechanism results in a disturbance of yin and yang, a mixture of cold and heat, and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory, clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill (乌梅丸) is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation, thereby restoring its free flow, achieving yin and yang balance, and ensuring nourishment to the ocular system.

ObjectiveTo investigate the effects of foliar fertilizer of nano-calcium carbonate and calcium nitrate tetrahydrate on the agronomic traits, carbohydrate and endogenous hormone contents of Dendrobium officinale planted for 1 year under greenhouse cultivation, in order to provide scientific basis for fertilization to improve the yield and quality of D. officinale. MethodsSingle-factor experimental design was adopted. Starting from early spring, D. officinale was treated with foliar spraying according to corresponding fertilizers. Three treatment groups were established based on different fertilizers, namely, a blank group(clear water), a nano-calcium carbonate group(0.727 g·L-1 nano-calcium carbonate water-soluble fertilizer), and a calcium nitrate tetrahydrate group(1.091 g·L-1 calcium nitrate tetrahydrate water-soluble fertilizer). The frequency of spraying was three times per month, and the entire treatment process lasted for nine months. The effects of various treatments on the traits and relative chlorophyll content of D. officinale were dynamically monitored. Sampling was conducted at three specific time points:August 2, 2023, September 8, 2023, and November 1, 2023, respectively. The contents of glucose and mannose in D. officinale stems were determined by high performance liquid chromatography(HPLC), the content of soluble sugars in D. officinale stems and leaves was determined by phenol method, and enzyme-linked immunosorbent assay(ELISA) was used to detect the concentrations of cytokinin and auxin. ResultsCompared with the blank group, the treatments with nano-calcium carbonate and calcium nitrate tetrahydrate could significantly increase stem length, stem node number, leaf number, and tiller number. Among them, during the harvesting period in November, the stem length and tiller number, which are indicators related to the yield of D. officinale, increased by 60.85% and 19.23% after treatment with calcium nitrate tetrahydrate, and by 32.54% and 28.85% after treatment with nano-calcium carbonate, respectively. Compared with the blank group, treatments with nano-calcium carbonate and calcium nitrate tetrahydrate could promote the accumulation of sucrose in the stems and leaves of D. officinale to varying degrees, as well as the accumulation of polysaccharides, mannose, and glucose in the stems. In addition, nano-calcium carbonate treatment also facilitated the accumulation of fructose in the stems and leaves of D. officinale. Specifically, during the harvesting period in November, polysaccharides and mannose, which were the main active ingredients in D. officinale stems, increased by 28.48% and 29.36% after treatment with calcium nitrate tetrahydrate, and by 39.91% and 82.62% after treatment with nano-calcium carbonate, respectively. In addition, compared with the blank group, the concentrations of auxin in the stems and leaves of D. officinale were significantly increased after treatment with calcium nitrate tetrahydrate(P<0.05). Similarly, the concentrations of cytokinin and auxin in the stems of D. officinale were also elevated after treatment with nano-calcium carbonate. Correlation analysis further indicated that elongation growth and tillering of D. officinale stems after foliar spraying of nano-calcium carbonate and calcium nitrate tetrahydrate might be related to the accumulation of carbohydrates in the stems and leaves and the synergistic effect of auxin and cytokinin. ConclusionIn production practice, spraying nano-calcium carbonate and calcium nitrate tetrahydrate can promote the accumulation of cytokinin, auxin, and carbohydrate contents in the stems and leaves of D. officinale, and promote tillering and elongation growth of the stems.

Objective:
To investigate the expression and functional role of FK506 binding protein 10 (FKBP10) in oral squamous cell carcinoma (OSCC), and to provide a research basis for the estimated prognosis and targeted therapy of OSCC.
Methods:
A total of 284 OSCC samples and 19 normal samples were selected from the Cancer Genome Atlas (TCGA) database, and diagnostic analysis was performed to determine mRNA expression. Survival analysis for FKBP10 and OSCC was conducted on a gene expression profile interaction analysis website. Real-time fluorescence quantitative PCR and Western Blot were used to detect the mRNA and protein expression of FKBP10 in four OSCC cell lines and SAS and SCC9 cells transfected with siRNA. The cell proliferation ability of FKBP10-silenced cells was detected using the CCK8 method, and the cell cycle distribution and apoptosis were detected by flow cytometry. Cell migration and invasion ability were detected through wound healing and invasion experiments. The expression changes of total protein and phosphatidylinositol 3-kinase (PI3K)-serine/threonine kinase (AKT) after FKBP10 silencing were analyzed by proteomics and Western Blot.
Results:
According to the analysis of gene expression levels, the mRNA expression level of FKBP10 in OSCC was significantly higher than that in normal tissues (P < 0.001). In terms of diagnosis, the expression level of FKBP10 has unique diagnostic value for OSCC (P < 0.05). The survival analysis of FKBP10 and OSCC showed that a high expression of FKBP10 led to a decrease in patient survival and poor prognosis (P < 0.05). The expression of FKBP10 mRNA and protein in OSCC cell lines was higher than that in normal oral keratinocytes (P < 0.001). Silencing FKBP10 can reduce the proliferation, invasion, and migration ability of SAS and SCC9 (P < 0.001), and also block their cell cycle in the G0/G1 phase (P < 0.001), with a significant increase in apoptosis (P < 0.05). Protein mass spectrometry and Western blot analysis revealed that FKBP10 silencing significantly downregulated the expression of multiple proteins in the RAP1 signaling pathway, mainly RAP guanine nucleotide exchange factor 1 (RAPGEF1) (P < 0.05) and the phosphorylation of PI3K-AKT proteins (P < 0.05).
Conclusion
FKBP10 is highly expressed in OSCC, leading to poor prognosis for patients. Downregulated FKBP10 expression can inhibit the proliferation, migration, and invasion ability of OSCC cells, hinder cell cycle progression, and promote apoptosis via the RAP1-PI3K-AKT axis. FKBP10 is a potential therapeutic target and prognostic biomarker for OSCC.

Objective To assess the situation and influencing factors of occupational burnout among the staff at the Center for Disease Control and Prevention (CDC) in Sichuan Province. Methods A total of 1 038 CDC staff members in Sichuan Province were selected as the study subjects using the stratified random sampling method. Occupational burnout of the staff was assessed using the Maslach Burnout Inventory General Survey via an online questionnaire. Results The detection rate of occupational burnout was 42.3% (439/1 038). Binary logistic regression analysis result showed that, after controlling for confounding factors such as education level and alcohol consumption, CDC staffs aged at 20-<31, 31-<41, and 41-<51 years were at higher risk of occupational burnout compared with those ≥51 years (all P<0.05). CDC staffs with 5-<10 or ≥10 years of service had higher occupational burnout risk compared with those with <5 years (both P<0.05). CDC staffs with poor or fair health status, irregular diet, and poor sleep quality had higher risk of occupational burnout compared with those healthy, have regular diet, and good sleep quality (all P<0.05). The risk of occupational burnout increased with higher overtime frequency (all P<0.05). Conclusion Occupational burnout among CDC staffs in Sichuan Province is relatively high. Age, years of service, health status, diet, sleep quality, and overtime frequency are key influencing factors.

AIM: To examine how three distinct central positioning techniques for anterior capsulotomy-pupil center, limbus center, and lens apex-affect intraocular lens(IOL)placement and visual quality following femtosecond laser-assisted cataract surgery(FLACS).METHODS: A total of 36 patients(72 eyes)with age-related cataracts who underwent FLACS and ZCB00 aspherical IOL implantation at Aier Eye Hospital Medical Center, Anhui Medical University between January and December 2023 were included in this prospective study. Patients were divided into three groups based on the central positioning mode for anterior capsulotomy: pupil center, limbus center, and lens apex center groups. IOL alignment and displacement were evaluated using the Casia2 device, and the postoperative visual quality was assessed.RESULTS: At 1 d postoperatively, the IOL tilt for the pupil, limbus, and apex groups were 3.96°±1.51°, 4.63°±1.87°, and 3.90°±2.24°, respectively(F=1.07, P=0.35); IOL decentration values were 0.21±0.10 mm, 0.23±0.16 mm, and 0.21±0.12 mm, respectively(F=0.14, P=0.87); total higher-order aberrations were 0.32±0.40 μm, 0.56±0.61 μm, and 0.53±0.60 μm, respectively(F=1.38, P=0.26); and coma aberrations values were 0.13±0.10 μm, 0.16±0.15 μm, and 0.14±0.15 μm, respectively(F=0.3, P=0.74). All results obtained postoperative day 1 did not differ significantly. At 3 mo postoperatively, IOL tilt values were 5.42°±2.00°, 3.96°±1.44°, and 3.20°±1.19°, respectively(F=12.40, P<0.001); IOL decentration values were 0.33±0.07 mm, 0.23±0.11 mm, and 0.21±0.11 mm, respectively(F=4.99, P=0.008); total higher-order aberrations were 0.67±0.29 μm, 0.44±0.37 μm, and 0.42±0.19 μm, respectively(F=5.50, P=0.006); and coma aberrations values were 0.21±0.12 μm, 0.19±0.12 μm, and 0.12±0.11 μm, respectively(F=3.87, P=0.03). All results obtained 3 mo postoperatively were statistically significant.CONCLUSION: Using the lens apex as the central positioning mode for anterior capsulotomy in FLACS improves postoperative IOL stability and reduces postoperative IOL tilt and decentration. If the lens apex cannot be determined intraoperatively, the limbus center-positioning mode is recommended.

In recent years, gastrointestinal stromal tumors (GIST) have increased incidence and mortality, and most GIST is caused by the activation mutation of the c-KIT gene. Therefore, c-KIT has become a promising therapeutic target of GIST. At present, the drugs approved for the treatment of GIST including imatinib, sunitinib, regorafenib and ripretinib, are mostly prone to developing resistance and accompanied by various degrees of adverse reactions. Therefore, there is an urgent need to develop new c-KIT inhibitors to solve the problem of resistance. In this study, we investigated the anti-tumor effect of a novel c-KIT inhibitor PN17-1 on gastrointestinal stromal tumor GIST-882 cells
