Objective: To explore the effects of the school based integrated horticulture curriculum intervention on 24 hour activity behaviors among third grade primary school students, so as to provide reference for promoting children s health. Methods: In September 2023, a convenience sampling method was used to select 90 third grade primary school students from a primary school in Changsha. Participants were randomly assigned to an intervention group ( n =45) and a control group ( n =45) using a random number table. From February to May 2024, the intervention group received a 12 week integrated curriculum intervention, consisting of two 60 minute sessions per week and covering horticultural practice, home-school collaborative tasks and nutrition knowledge education. The control group continued with routine labor education courses. The triaxial accelerometer and multi sensor sleep monitoring device were used to objectively measure light intensity physical activity (LPA), moderate to vigorous physical activity (MVPA), screen based sedentary behavior (SSB) and sleep (SLP), durations in both groups. Data were analyzed using generalized estimating equations (GEE) and Mann-Whitney U tests. Results: The time, group and interaction effects of MVPA time and SLP time before and after intervention in two groups of primary school students were not statistically significant (Wald χ 2=1.54, 2.97, 0.85 ; 0.75, 1.05, 0.48), and the group effect of LPA time (Wald χ 2=1.24) and the time and group effects (Wald χ 2=3.02, 1.18 ) were not statistically significant (all P >0.05). There were statistically significant time and interaction effects for LPA time, as well as interaction effect for SSB time in two groups of primary school students before and after intervention (Wald χ 2=4.78, 3.95, 12.60, all P <0.05). After intervention, LPA time of intervention group [152.23(59.15, 245.80)min] was higher than that of control group [120.70(29.90, 201.20)min], and SSB time of intervention group [55.50(30.00, 125.50)min] was lower than that of control group [220.00(60.00, 285.00)min], with statistically significant differences ( Z =-2.46, -4.48, both P <0.05). Conclusion The school horticulture curriculum effectively enhances daily LPA and reduces SSB among third grade primary school students.

ObjectiveTo investigate the protective effect and mechanism of Wendan Ningxin granules （WNG） on susceptibility to atrial fibrillation （AF） in mice with inflammatory injury. Methods100 C57BL/6 mice were divided into a blank control group， a model group， a low-dose WNG group （2.34 g·kg^-1·d^-1）， a high-dose WNG group （4.68 g·kg^-1·d^-1）， and an amiodarone positive control group （0.091 g·kg^-1·d^-1）， with 20 mice in each group. Except for the blank control group， mice in other groups received intraperitoneal injections of lipopolysaccharide （LPS） to establish an inflammatory injury model. Treatment groups received continuous intragastric administration of their respective interventions for four weeks. During the fourth week， the treatment groups received LPS injections concurrently with their treatments. The blank control and model groups received distilled water （10 mL·kg^-1·d^-1） by gavage， with a gavage volume of 10 mL·kg^-1 for all groups， once daily. Hematoxylin-eosin （HE） staining and Sirius red staining were used to observe atrial tissue morphology and fibrosis degree. Immunohistochemistry was used to assess the expression of α-smooth muscle actin （α-SMA） in mouse atrial tissue. Electrophysiological detection was performed using a multi-channel electrophysiology mapping system to measure AF inducibility， AF duration， and atrial effective refractory period （AERP）. High-resolution optical mapping was used to measure action potential duration （APD） dispersion， conduction heterogeneity index， and calcium transient （CaT） dispersion. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of proteins related to diastolic calcium leakage in mouse atria： Ca²⁺/calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）， ryanodine receptor 2（RyR2）， sarco/endoplasmic reticulum Ca²⁺-ATPase （SERCA）， and sodium-calcium exchanger （NCX）. Western blot analysis was performed to detect the expression of CaMKII， RyR2， SERCA， and NCX proteins in myocardial tissue from each group. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of inflammatory factors interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）. ResultsPathological staining results showed that compared with the blank control group， the model group exhibited disrupted atrial tissue structure， inflammatory cell infiltration， atrial fibrosis， and diffuse infiltration of numerous brown α-SMA positive cells in the atrial interstitium （P<0.01）. AF could be induced by electrical stimulation with a longer duration. AERP was shortened， while APD dispersion， conduction heterogeneity index， and CaT dispersion were increased （P<0.01）. The expression of proteins associated with diastolic calcium leakage， including CaMKⅡ， RyR2， and NCX1， showed elevated mRNA and protein levels， whereas SERCA2a mRNA and protein expression decreased （P<0.05）. Serum levels of inflammatory factors IL-1β and TNF-α were elevated （P<0.01）. Compared with the model group， intervention with WNG alleviated cardiac structural damage， reduced inflammatory cell infiltration， improved atrial fibrosis， and reduced the diffuse infiltration of α-SMA positive cells （P<0.01）. AF inducibility and AF duration upon electrical stimulation were significantly reduced （P<0.05）， AERP was prolonged （P<0.05）， mRNA and protein expression of CaMKⅡ， RyR2， and NCX1-proteins associated with diastolic calcium leakage-were reduced， whilst mRNA and protein expression of SERCA2a increased （P<0.05）， and serum levels of IL-1β and TNF-α were decreased （P<0.01）. ConclusionBoth low‑ and high‑dose WNG can effectively reduce susceptibility to inflammation-related AF. The mechanism by which WNG reduce AF susceptibility may be related to regulating proteins involved in sarcoplasmic reticulum diastolic calcium leak， thereby improving cardiac electrical remodeling， and alleviating inflammation-induced myocardial fibrosis， thus improving cardiac structural remodeling.

Radiotherapy is a crucial treatment modality for head and neck tumors. However, while effectively killing tumor cells, it significantly disrupts the homeostasis of the oral microecology, which is closely associated with various complications such as radiation-induced oral mucositis. Literature review indicates that as radiotherapy doses accumulate and treatment durations extend, the richness and diversity of the oral microbiota show a declining trend, with the genus Streptococcus decreasing most markedly. In contrast, radiotherapy selectively promotes the proliferation of bacterial phyla such as Proteobacteria and Bacteroidetes, which are rich in opportunistic pathogens. Mechanistically, radiotherapy activates the nuclear factor-kappa B pathway, triggering chronic inflammation and oxidative stress, damaging the epithelial barrier, suppressing local immunity, and causing damage to organs such as the salivary glands. It can also induce systemic diseases via the oral-gut axis, forming a multi-level, interconnected pathogenic network. In terms of interventions, treatment strategies including probiotics and prebiotics have shown promising efficacy against side effects such as radiation-induced oral mucositis. Saliva-based oral microbiota transplantation is an emerging strategy that is expected to become widely utilized for restoring oral microecological balance. Existing interventions provide preliminary pathways for clinical practice, but this field still faces several key scientific questions. The association between oral microecology and systemic diseases remains largely correlative, lacking causal evidence. Furthermore, critical parameters for oral microbiota transplantation, such as donor screening criteria, transplantation protocols, and long-term safety, are not yet well-defined. Therefore, future research should focus on conducting large-scale clinical trials to establish standardized protocols and safety evaluation systems for oral microecological interventions, and explore combined treatment therapies such as probiotics, prebiotics, and microbiota transplantation to advance the development of personalized precision modulation. These will enable more effective management of radiotherapy-induced oral microecological dysbiosis and improve treatment outcomes and quality of life for patients with head and neck tumors.

Objective: To evaluate the diagnostic potential of fluid suppression (FS) techniques combined with amide proton transferweighted imaging (APTw) for assessment of isocitrate dehydrogenase (IDH) mutation status, glioma subtypes, and tumor proliferation. Materials and Methods: This retrospective study included 117 patients with adult-type diffuse gliomas. Conventional APTw, FSAPTw, and spillover-corrected FS-APTw (SCFS-APTw) metrics were calculated from 3T MRI data in tumor parenchyma, necrotic or cystic regions, and contralateral normal-appearing white matter. APTw signals were compared across the three techniques within each region, between IDH-mutant and IDH-wildtype gliomas, and among astrocytoma, oligodendroglioma, and glioblastoma subtypes. Diagnostic performance for distinguishing IDH mutation status and glioma subtypes was assessed using receiver operating characteristic (ROC) analysis. Correlations between APTw metrics and Ki-67 expression were also analyzed. Results: Both FS-APTw and SCFS-APTw significantly reduced signal intensity in tumor parenchyma and necrotic or cystic regions, with SCFS-APTw demonstrating a stronger suppression effect. IDH-wildtype gliomas showed significantly higher APTw metrics than IDH-mutant gliomas (all P < 0.001). Glioblastomas exhibited significantly higher metrics than oligodendrogliomas (all corrected P ≤ 0.015) and astrocytomas (all corrected P < 0.001). SCFS-APTw achieved the highest area under the ROC curve (AUC) of 0.846 for identification of IDH mutation status. For differentiation between astrocytomas and glioblastomas, the 90th percentile of APTw yielded the highest AUC (0.860), followed by SCFS-APTw (0.849). For discrimination between oligodendrogliomas and glioblastomas, the highest AUC (0.832) was obtained using the 90th percentile of SCFS-APTw. None of these metrics successfully differentiated oligodendrogliomas from astrocytomas. SCFS-APTw demonstrated the strongest correlation with Ki-67 expression (r = 0.451). Conclusion FS techniques effectively reduce elevated APTw signals originating from fluid compartments. Their combination with APTw imaging enables evaluation of IDH mutation status, glioma subtypes, and tumor proliferative activity in adulttype diffuse gliomas.

ObjectiveTo investigate the effect of SU056， an azo-podophyllotoxin derivative， on carbon tetrachloride （CCl₄）-induced liver fibrosis in mice and related mechanisms of action. MethodsA total of 12 mice were randomly divided into control group， model group （CCl₄+normal saline）， and treatment group （CCl₄+SU056）， with 4 mice in each group. Mice were given intraperitoneal injection of CCl₄ to establish a model of liver fibrosis， and during the middle stage of modeling， the mice in the treatment group were given daily intraperitoneal injection of SU056. Liver histopathological injury， collagen deposition， and liver function were assessed based on HE staining， Masson staining， Sirius Red staining， the content of hydroxyproline in liver tissue， and the serum levels of alanine aminotransferase and aspartate aminotransferase， and immunofluorescence assay was used to measure the expression levels of smooth muscle actin α （α-SMA）， collagen type Ⅰ， and Y-box binding protein 1 （YB1）. The human hepatic stellate cell （HSC） line LX-2 and primary mouse HSC were used， and CCK-8 assay was used to measure cell proliferation； Transwell assay was used to observe cell migration； quantitative reverse transcription-polymerase chain reaction and Western Blot were used to measure the expression levels of collagen type Ⅰ， collagen type Ⅲ， YB1， phosphorylated mammalian target of rapamycin （mTOR）， and phosphorylated S6K， so as to validate the function of the YB1/mTOR signaling axis. The one-way or two-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsIn the mouse model of liver fibrosis induced by CCl₄， compared with the model group， the treatment group had significant alleviation of inflammatory cell infiltration， collagen deposition， and pseudolobule formation in liver tissue and significant reductions in the serum levels of alanine aminotransferase and aspartate aminotransferase and the content of hydroxyproline in liver tissue （all P<0.01）. Immunofluorescence assay showed that SU056 significantly inhibited the abnormal high expression of α-SMA， collagen type I， and YB1 in liver tissue （all P<0.01）. In vitro experiments showed that SU056 inhibited the transforming growth factor-β1-induced proliferation of LX-2 cells （P<0.01）， the migration of LX-2 cells （P<0.05）， and the transcriptional up-regulation of collagen type Ⅰ and collagen type Ⅲ （all P<0.05） in a dose-dependent manner， and SU056 could inhibit the spontaneous activation of primary HSC in vitro. Mechanistic studies revealed that transforming growth factor-β1 simultaneously upregulated the expression levels of YB1， phosphorylated mTOR， and phosphorylated S6K in LX-2 cells， and treatment with SU056 （10 and 20 µmol/L） could downregulate the protein expression levels of collagen type I， YB1， phosphorylated mTOR， and phosphorylated S6K. Specific knockdown of YB1 or administration of the mTOR inhibitor rapamycin exerted a similar effect as SU056. SU056 also inhibited the co-upregulation of α-SMA and phosphorylated mTOR in liver tissue of model mice （P<0.01）. ConclusionSU056 can effectively inhibit HSC activation， proliferation， migration， and extracellular matrix production both in vivo and in vitro and thus delay the progression of liver fibrosis， by disrupting the YB1/mTOR positive feedback signaling axis.

Psychological factors have become significant contributors to the onset and progression of insomnia. This article explored the treatment of insomnia from the perspective of “liver governs wei qi （defensive qi）”. The concept of “liver governs wei qi （defensive qi）” is summarized in three aspects， firstly， the liver assists the spleen and stomach in transformation and transportation， governing the generation of wei qi； secondly， the liver aids lung qi diffusion and dispersion， governing the distribution of wei qi； thirdly， the liver regulates circadian rhythms， governing the circulation of wei qi. It is proposed that the clinical treatment of insomnia should focus on the following methods： for regulating the liver to harmonize the five viscera， and facilitate the circulation of wei qi， medicinals entering the liver channel include Chaihu （Bupleuri radix）， Baishao （Paeoniae Radix Alba）， Zhizi （Gardeniae Fructus）， and Suanzaoren （Ziziphi Spinosae Semen） could be commonly used； for nourishing the liver， the treatment should align with the day-night rhythm， and herbs such as Baihe （Lilium）， Hehuan （Albizia julibrissin）， and Yejiaoteng （Polygoni multiflori caulis） are commonly used； for soothing the liver and address both mental and physical health to calm wei qi， treatment should advocate verbal counseling， psychological regulation， and health education. Ultimately， this treatment approach can free liver qi to flow， soothe qi movement， restore the motion of wei qi， regulate during day and night， balance yin and yang， and resolve insomnia effectively.

The Solomon four-group design， a critical method for improving internal validity in clinical research， can reduce bias and control the interference of Hawthorne effects and pretest sensitization on research results， which offers unique advantages in evaluating complex intervention outcomes. This paper systematically outlined the core framework and key points of statistical analysis of the Solomon four-group design， summarized its applications in clinical research at home and abroad， explored its advantages and limitations， and discussed the potential value in traditional Chinese medicine （TCM） clinical trials. It is believed that the Solomon four-group design can help distinguish between testing effects and intervention effects in TCM clinical studies， and reduce the bias in the evaluation of subjective indicators. Meanwhile， given the complexity of the Solomon four-group design and the particularity of TCM clinical research， it is proposed that future TCM clinical studies should focus on using psychological scales， know-ledge， attitude， and behavior measurements， and other similat evaluations as endpoints. It also advocates strengthening interdisciplinary collaboration to provide new methodological paths for TCM clinical research.

Objective:To evaluate the efficacy of bevacizumab in reducing dyspnea, avoiding tracheostomy, and assessing the overall safety and effectiveness of the treatment in patients with juvenile-onset recurrent respiratory papillomatosis (JORRP).Methods:This study included 19 patients with JORRP treated with Bevacizumab at the Department of Otolaryngology-Head and Neck Surgery, BenQ Medical Center, from March 2022 to June 2024. The age of patients ranged from 1.0 to 27.0 years (10.47±8.45 years), with age at onset ranging from 0.5 to 15.0 years (3.66±3.70 years). The cohort included 11 males and 8 females. Bevacizumab was administered intravenously at a dose of 10 mg/kg every three weeks for three sessions. Efficacy was evaluated by comparing the standardized lesion volume pre-and post-treatment, with statistical analysis performed using R software (4.3.1).Results:Among the 19 patients, 11 presented with dyspnea before treatment. All patients experienced varying degrees of dyspnea relief within 72 hours following the initial treatment, and only one patient had mild dyspnea by the second treatment session three weeks later. The average reduction rates at 24 and 48 hours post-initia treatment were 25.75% and 47.16%, respectively. Following three treatment cycles, the average cumulative reduction rate was 67.47%, significantly higher than after the first treatment ( Z=3.38, P=0.002). Throughout the treatment period, no adverse events that of grade 2 or higher were noted. Conclusions:Bevacizumab can rapidly alleviate dyspnea symptoms and significantly reduce lesion volume in JORRP patients, exhibiting satisfactory overall safety and effectiveness. However additional large-scale prospective studies are warranted to validate its long-term safety and efficacy.
