Chinese Journal of School Health 2025;46(2):244-248
Objective:
To analyze the relationship between 24 h movement behaviors and cognitive function in children and adolescents, as well as the isotemporal substitution benefits, in order to provide a basis for developing cognitive development intervention strategies among children and adolescents.
Methods:
Relevant studies were searched in the Web of Science, PubMed, Embase, EBSCO, and China National Knowledge Infrastructure databases from their inception to November 30, 2024. Systematic evaluation was performed after document screening, data extraction and quality assessment.
Results:
A total of 24 highquality studies were included, comprising 35 295 children and adolescents aged 3-18 years. Adhering to the 24 h activity guidelines was associated with better cognitive performance (19 studies). Additionally, substituting 5-30 minutes per day of moderate to vigorous physical activity (MVPA) or sleep (SLP) for sedentary behavior (SB) or light physical activity (LPA) were associated with improvements in cognitive function (7 studies). There were inconsistencies in the effects of different types of SB (learning or entertainment) on cognitive function.
Conclusions
Adherence to the 24 h activity guidelines supports cognitive development in children and adolescents, with MVPA and SLP as key intervention targets. Increasing the proportion of MVPA, ensuring adequate SLP, and limiting recreational SB and screen time might be helpful to enhance the combined benefits of these three behaviors.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

ObjectiveThis study aims to investigate the therapeutic effects of Wenweishu granule (WWSG) on functional dyspepsia (FD) with spleen-stomach deficiency cold syndrome in rats by integrating network pharmacology, molecular docking, and animal experiments. MethodsActive components and corresponding targets of WWSG were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM). Disease-related targets for FD with spleen-stomach deficiency cold syndrome were screened using GeneCards and the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP). Core therapeutic targets were identified via Cytoscape and validated by molecular docking. A rat model of FD with spleen-stomach deficiency cold syndrome was established using vinegar gavage combined with tail-clamping. The rats were randomly divided into a model group, low-, medium-, and high-dose WWSG groups (2.0, 4.0, 8.0 g·kg-1), a domperidone group (3.0 mg·kg-1), a Fuzi Lizhong pillwan (0.8 g·kg-1), and a normal control group (n=10 per group). Drugs were administered once daily by gavage for 14 consecutive days. After treatment, body weight, symptom scores, and gastrointestinal motility indices were recorded. Gastric and duodenal pathologies changes were observed via hematoxylin-eosin (HE) staining. Brain-gut peptides were measured in serum and tissue using enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry and Western blot were performed to assess stem cell factor (SCF) and receptor tyrosine kinase (c-Kit) protein expression in gastric tissues. ResultsA total of 305 drug targets, 1 140 disease targets, and 116 overlapping targets were identified. Cytoscape analysis revealed 104 core targets. Enrichment analysis indicated that the SCF/c-Kit signaling pathway was the key mechanism. Molecular docking confirmed a strong binding affinity between active components of WWSG and SCF/c-Kit proteins (binding energy<-5.1 kcal·mol-1). Compared with the normal group, model rats exhibited slower weight gain (P<0.05), reduced gastric emptying and intestinal propulsion (P<0.01), mild gastric mucosal shedding, duodenal inflammatory cell infiltration, decreased levels of gastrin (GAS), 5-hydroxytryptamine (5-HT), and vasoactive intestinal peptide (VIP) (P<0.05, P<0.01), and elevated somatostatin (SS) expression (P<0.05, P<0.01). WWSG treatment ameliorated weight gain, symptom scores, and low-grade inflammation in gastric/duodenal tissues. High-dose WWSG significantly improved gastric emptying and intestinal propulsion, upregulated GAS, 5-HT, and VIP, and downregulated SS expression in serum and tissues (P<0.05, P<0.01). Immunohistochemistry and Western blot demonstrated that SCF and c-Kit protein expression was decreased in the model group (P<0.05, P<0.01), which was reversed by WWSG intervention (P<0.05). ConclusionWWSG exerts therapeutic effects on FD with spleen-stomach deficiency cold syndrome in rats, potentially by regulating the SCF/c-Kit signaling pathway to enhance gastrointestinal motility.

The statement of"qi transformation leading to the removal of pathogenic dampness"was recorded in Wen Bing Tiao Bian(Analysis on Epidemic Febrile Diseases)written by the Qing Dynasty physician WU Ju-Tong.Dampness in the triple energizer is caused by the dysfunction of qi transformation,and the treatment of dampness must be based on the activation of qi movement and focused on the promotion of qi movement and the restoration of the qi transformation in the triple energizer.For the treatment of dampness attack in the upper energizer,therapies of dispersing lung to smooth qi and resolving dampness to relieve the obstruction are recommended.For the treatment of dampness obstruction in the middle energizer,therapy of activating spleen qi by strengthening spleen and moving qi is stressed for helping the removal of dampness and for the eradication of the source of dampness.For the treatment of dampness stagnation in the lower energizer,therapy of draining dampness with sweet-light medicines and activating yang can be used according to the illness status.The three methods of treating dampness,namely dispersing the upper energizer,activating the middle energizer and draining the lower energizer,all embody the mechanism of"qi transformation leading to the removal of pathogenic dampness",and the therapies of dispersing lung with light medicines,inducing perspiration by opening striated layer,eliminating dampness with aromatics and draining dampness with sweet-light medicines should be used in accordance with the syndromes.The elucidation of the academic thoughts of"qi transformation leading to the removal of pathogenic dampness"can provide theoretical reference for the fundamental research of dampness syndrome and clinical application of therapies for resolving dampness in Chinese medicine.

OBJECTIVE To create a highly effective algorithm for automatically generating easily confused drug catalogs (ECDC), as well as to develop a management system for ECDC based on this algorithm, in order to improve the management efficiency of ECDC. METHODS This study, based on Levenshtein distance algorithm, delved deeply into the automatic identification mechanism of easily confused drugs and the screening method for determining similarity thresholds, ultimately leading to the development of an algorithm for automatically generating ECDC. Besides a management system was designed and developed, using SQL Server 2008 R2 Express as the data storage platform and Visual Basic.NET as the programming language. RESULTS The similarity threshold δ played a crucial role in the algorithm for automatically generating ECDC. As the value of δ gradually increased, the total count of easily confused drugs decreased gradually, while the count of drug groups exhibited a pattern of initially increasing and then decreasing. Practically, ECDC could be created using either the generic or varietal names of drugs, with corresponding similarity thresholds of 0.75 and 0.83. Furthermore, ECDC management system had significantly reduced the time required to establish a catalog from about one week to less than one hour, resulting in a substantial enhancement in work efficiency. CONCLUSIONS The algorithm used to automatically generate ECDC is highly efficient and rapid, offering robust technical assistance for the management of easily confused drugs. Implementing the ECDC system can greatly reduce the time cost related to building and maintaining the catalogs, thus significantly improving the efficiency of managing ECDC.

ObjectiveTo investigate the effect of Rehmanniae Radix Praeparata on neurological function injury in ischemic stroke rats and explore its mechanism. MethodMale SD rats were randomized into sham operation, model, low- and high -dose (3.5 g·kg-1 and 7 g·kg-1) Rehmannia Radix Praeparata, and nimodipine (0.01 g·kg-1) groups. The rat model of middle cerebral artery occlusion (MCAO) was established with the modified suture occlusion method. Zea-Longa 5-point scoring was employed to evaluate the neurological function of rats. The cerebral infarction volume was detected by 2,3,5-triphenyltetrazolium chloride (TTC) staining. Hematoxylin-eosin staining and Nissl staining were employed to observe the morphology and damage of the brain tissue. Meanwhile, the serum levels of lactate dehydrogenase (LDH), oxidative stress-related indicators superoxide dismutase (SOD), glutathione peroxidase 4 (GPX4), and malondialdehyde (MDA), and the iron (Fe) content in the brain tissue were determined. To explore the mechanism of Rehmanniae Radix Preparata in mitigating the neurological damage in ischemic stroke rats, Western blotting was employed to determine the expression levels of proteins in the ischemic brain tissue. The autophagy-associated proteins included autophagy effector (beclin-1), microtubule-associated protein light chain 3 (LC3B), and ubiquitin-binding protein p62 (p62). The ferroptosis-associated proteins included transferrin (TF), transferrin receptor 1 (TFR1), ferritin heavy chain 1 (FTH1), and ferropotin (FPN1). The neurological function injury-associated proteins included brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB). ResultCompared with the sham operation group, the model group showed increased neurological function score, cerebral infarction volume, and appearance of nuclear pyknosis and vacuole of cells in the cerebral cortex. In addition, the model group presented elevated levels of LDH, MDA, and Fe (P<0.01) and lowered levels of SOD and GPX4 (P<0.01). Compared with the model group, Rehmanniae Radix Praeparata decreased the content of LDH, MDA, and Fe (P<0.05, P<0.01) and elevated the levels of SOD and GPX4 (P<0.05, P<0.01). Compared with the sham operation group, the modeling promoted the expression of beclin-1,LC3B Ⅱ/Ⅰ, TF, and TFR1 and inhibited the expression of p62, FTH1, FPN1, BDNF, and TrkB (P<0.01). The expression levels of these proteins were recovered after the treatment with Rehmanniae Radix Praeparata. ConclusionRehmanniae Radix Praeparata may inhibit ferroptosis and improve the neurological function in ischemic stroke rats by down-regulating the autophagy level in the brain tissue.

Objective:To understand the current antiviral treatment status and various clinical types of treatment plans in Xiamen City so as to explore ways to improve and optimize the diagnosis and treatment standards for chronic hepatitis B.Methods:A cross-sectional survey method was used to study the antiviral treatment status and treatment plans for chronic hepatitis B patients who visited and were diagnosed in the Department of Infectious Diseases and Hepatology of all tertiary hospitals in Xiamen City at 0:00~23:59 on May 25, 2022.Results:A total of 665 cases were surveyed in this study, with an antiviral treatment rate of 81.2%(540/665). The antiviral treatment rate of patients who accorded with the current guidelines for antiviral treatment indications was 85.8%(507/591). The antiviral treatment rate for 362 outpatients was 72.9%(264/362). Among them, the antiviral treatment rates were 80.1%, 89.3%, and 25.0%(226/282, 25/28, 13/52), respectively, for patients diagnosed with chronic hepatitis B, hepatitis B cirrhosis, and hepatitis B surface antigen-carrying status. The treatment plan for all outpatient patients was mainly oral nucleos(t)ide analogues, accounting for 59.1%(214/362). The antiviral treatment rate for 303 inpatients was 91.1%(276/303). The various clinical types of antiviral therapy rates among all patients were 70%~95%. The antiviral treatment plan for inpatients was mainly based on pegylated interferon alpha treatment, accounting for 72.6%(220/303).Conclusion:Antiviral treatment for chronic hepatitis B in Xiamen City can still be strengthened to meet the current demand for expanding antiviral treatment indications. Antiviral treatment rates and various types of treatment plans differ between outpatients and inpatients; thus, further awareness and acceptance of the goal of improving antiviral therapy, especially in outpatients, and the possibility for a clinical cure based on pegylated interferon alpha treatment are needed to maximize the benefit to more patients.
