OBJECTIVES: The 24-hour movement behaviors, comprising physical activity, sedentary behavior, and sleep, are crucial factors affecting children's mental health. This study aims to explore the longitudinal association between 24-hour movement behaviors and psychological well-being in overweight and obese children, providing empirical evidence for mental health promotion in this population. METHODS: A total of 445 overweight and obese children were recruited via stratified cluster random sampling from a provincial capital city in China and followed up for one year. Measures included objectively assessed physical activity and sleep duration using triaxial accelerometers (ActiGraph GT3X+), parent-reported sedentary screen-based time (SST), and self-reported psychological well-being. RESULTS: After one year, the proportion of children meeting all 3 movement guidelines increased from 10.11% to 11.68%, while those meeting none increased from 11.24% to 15.06%. After adjusting for relevant covariates, children who met individual guidelines for moderate-to-vigorous physical activity (MVPA) (β=0.377, 95% CI 0.209 to 0.545), sleep (β=0.187, 95% CI 0.042 to 0.332), or guideline combinations of MVPA+SST (β=0.545, 95% CI 0.377 to 0.713) and MVPA+sleep (β=0.602, 95% CI 0.449 to 0.755) showed significant improvements in psychological well-being after one year. Additionally, an increase in the number of guidelines met was significantly associated with improved well-being (β=0.113, 95% CI 0.011 to 0.214). CONCLUSIONS Adherence to any single movement guideline, especially MVPA or sleep, and combinations such as MVPA+SST or MVPA+sleep is significantly associated with enhanced psychological well-being in overweight and obese children. Integrated behaviors may be an effective strategy to improve mental well-being in this population.

Objective:To analyze the relationship between the expression level of calumenin(CALU)and the prognosis of hepatocellular carcinoma(HCC)patients by bioinformatics tools and establish the prognostic prediction nomogram,and to clarify its possible mechanism.Methods:The data of 374 HCC tissue samples were downloaded from The Cancer Genome Atlas(TCGA)database and the data of 160 normal tissue samples were down loaded from Genotype-Tissue Expression(GTEx)database.Paired sample t-test was used to analyze the difference in CALU expression between the HCC tissue samples and the paired adjacent normal tissue samples.Human Protein Atlas(HPA)database was used to verify the results.DESeq2 package was used to screen the differentially expressed genes(DEGs)between CALU low expression group and CALU high expression group in the HCC tissue samples.R package pROC was used to analyze the receiver operating characteristic(ROC)curve.Univariate and multivariate Cox regression analyses were used to confirm the prognosis value of CALU in the HCC patients with different clinicopathological characteristics,and ggplot2 package was used to construct the forest plot.R packages rms and survival were used to construct the nomogram and its calibration curve,and the diagnostic value of CALU in distinguishing HCC tissue from normal tissue was analyzed.The data from Kaplan-Meier Plotter database were used to further verify the relationship between CALU and the prognosis of HCC patients.The gene transcriptional expression data of 216 HCC samples obtained from GSE14520 dataset were used to verify the prediction accuracy of the nomogram.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were used to determine the function and enrichment pathways of the DEGs,and Gene Set Enrichment Analysis(GSEA)was used to obtain the significantly enriched gene sets of the DEGs.Single-cell sequencing data of 10 HCC tissue samples and 8 adjacent normal tissue samples obtained from GSE149614 dataset were used to verify the relationship between CALU and the prognosis of HCC patients and its mechanism.Results:Compared with normal tissue,the expression level of CALU mRNA in HCC tissue was significantly increased(P＜0.001),and the expression level of CALU protein in HCC samples was also increased.A total of 928 DEGs were identified between CALU low expression group and CALU high expression group in the HCC samples,including 784 upregulated DEGs and 144 downregulated DEGs.The ROC analysis results indicated that CALU showed high diagnostic value in distinguishing cancer tissue from adjacent non-cancer tissue with an area under curve(AUC)of 0.839.Kaplan-Meier survival analysis showed that the survival rate of HCC patients in CALU high expression group was significantly lower than that in CALU group low expression(P＜0.001).Univariate and multivariate Cox regression analyses results demonstrated that high expression of CALU was an independent risk factor of the prognosis in HCC patients,and a prognosis prediction nomogram was constructed.The applicability of nomogram on the prognosis of HCC was verified by GSE14520 dataset.The GO enrichment analysis results showed that DEGs were mainly enriched in pathways related to the oxidative stress,ferroptosis and cuproptosis(P＜0.05).The KEGG enrichment analysis results showed that DEGs were mainly enriched in the pathways related to extracellular matrix(ECM)receptor interaction,linoleic acid metabolism and neuroactive ligand receptor interaction(P＜0.05).The GSEA results showed that high expression of CALU may promote the G1-S phase transition of the cell cycle,ubiquitination protein polymerization and HCC progression,while low expression of CALU may activate oxidative stress,ferroptosis and cuproptosis in HCC cells.Single-cell sequencing analysis results showed that the expression level of CALU mRNA was significantly increased in HCC cells with advanced tumor stages.HCC_CALU_High cell subset was mainly related to ubiquitination,p53 and cell cycle(P＜0.01),and HCC_CALU_Low cell subset was mainly related to oxidative stress,ferroptosis,and histone binding(P＜0.01).Conclusion:The high expression of CALU may be related to the poor prognosis of HCC patients.The constructed nomogram of HCC prognosis shows favourable effect in predicting the survival rate of the HCC patients.The up-regulation of CALU may promote HCC progression by regulating the G1-S phase of the cell cycle and ubiquitination of protein,while down-regulation of CALU may inhibit HCC progression by inducing oxidative stress,ferroptosis and cuproptosis in cells.

Objective Through the analysis of the clinical characteristics of post-interventional complications of ventilator-associ-ated pneumonia(VAP)in patients with hypertension and acute large vessel occlusive cerebral infarction(AIS-LVO),we aim to develop and validate a risk prediction model.Methods We conducted a retrospective analysis of clinical data from 107 patients hospitalized for hypertension with AIS-LVO at Dongguan Hospital of Guangzhou University of Traditional Chinese Medicine between July 2020 and Au-gust 2023.Patients were categorized into two groups based on their hospitalization:the VAP group,consisting of 64 patients who devel-oped VAP,and the non-VAP group,comprising 43 patients who did not experience VAP.Least absolute shrinkage and selection opera-tor regression(LASSO)analysis was employed to identify potential predictors.Subsequently,a nomogram model was constructed using multifactorial Logistic regression analysis.The model's discriminative ability,calibration,and clinical utility were assessed using the area(AUC)under the receiver operating characteristic(ROC)curve,calibration curves,and decision curve analysis(DCA).Results In 107 patients with hypertension and AIS-LVO who underwent interventional surgery,the incidence of VAP was 59.8％.The results revealed statistically significant differences between the two groups in terms of age,presence of atrial fibrillation,admission national institutes of health stroke scale(NIHSS)score,admission glasgow coma scale(GCS)score,impaired consciousness,swallowing dysfunction,opera-tive time,postoperative 24-hour systemic inflammatory response index(SIRI),duration of mechanical ventilation,length of ICU stay,and the presence of an indwelling gastrostomy tube(P＜0.05).Additionally,the incidence of poor functional outcomes was 57.8％in the VAP group compared to 14.0％in the non-VAP group,indicating a worse prognosis for patients in the VAP group.The variables i-dentified through LASSO regression screening were included in a multifactorial Logistic regression analysis.This analysis revealed that the SIRI and the duration of mechanical ventilation were independent risk factors for the development of VAP following intervention in patients with hypertension and AIS-LVO(P＜0.05).Conversely,the admission GCS score was identified as a protective factor(P＜0.05).These three indicators were utilized to construct a prognostic nomogram model.The model's internal validity was assessed using the Boot-strap method with 1000 resamples,and the calibration curves were found to be in close agreement with the ideal fitted line,exhibiting a mean absolute error of 0.029,indicating good curve accuracy.The Logistic regression model's goodness of fit was evaluated using the Hos-mer and Lemeshow test,which yielded a x2 value of 5.38 and a P-value of 0.716,suggesting a good fit.The AUC of the model was 0.812(95％confidence interval 0.730-0.894),and the DCA indicated that the model has favorable clinical applicability.Conclusion A prediction model based on admission GCS score,postoperative 24-hour SIRI,and duration of mechanical ventilation demonstrates a robust predictive value for the incidence of VAP following intervention in patients with hypertension and acute ischemic stroke with AIS-LVO.

Objective: To identify the social ecological factors of individual, family, and physical environments for affecting the development of fundamental motor skills (FMS) among overweight and obese children, so as to provide a basis for the future intervention design and policy making. Methods: From March to April 2022, one public primary school was recruited from each of the 4 main urban areas in Shijiazhuang, and a total of 425 children in schools were recruited for data collection including individual, family, physical environmental factors, by using a stratified cluster random sampling approach. Test of Gross Motor Development-Third Edition (TGMD-3) was used to evaluate children s FMS. Hierarchical linear regression model was employed to analysis the associations between the 18 factors for individual, family, and physical environments, and the FMS of overweight and obese children. Results: Individual level including the child s age, gender and sleep duration, and family level including high family economic level, parental support for physical activity, and the physical activity environment surrounding the family and community were consistent predictors of movement skills ( B =0.422, -1.972, 0.014, 0.045, 1.042, 0.827, 1.898), ball skills ( B =0.858, 3.953, 0.013, 0.092, 2.141, 1.173, 1.954), and composite skills ( B =1.305, 1.915, 0.028, 0.142, 3.091, 1.962, 3.879) among overweight and obese children ( P <0.05). Furthermore, child s body mass index (BMI), moderate to vigorous physical activity, perceived motor competence, pleasure of exercise,as well as BMI and physical activity levels of their primary caregiver, were associated with different types of FMS ( P <0.05). Individual, family, and physical environmental factors had moderate to high predictive explanatory power for FMS among overweight and obese children ( 2=0.69, 0.75, 0.93, P <0.01). Conclusions The factors influencing the development of FMS in overweight and obese children are multifaceted, with individual, family, and physical environment factors all playing significant roles.Corresponding measures should be actively taken to improve FMS in overweight and obese children.

Objective:To investigate the effects of mesenchymal stem cells-derived exosomes (MSC-Exos) secreted by mesenchymal stem cells (MSCs) induced by astragaloside IV (AS-IV) on the biological function and pyroptosis of human umbilical vein endothelial cells (HUVECs) injured by high glucose.Methods:After human umbilical cord blood mesenchymal stem cells (hUCBMSCs) were intervened with 400 mg/L of AS-IV, exosomes were extracted, and then the morphology and specific markers of exosomes were identified. Human umbilical vein endothelial cells (HUVECs) were cultured in a medium with a glucose concentration of 30 mmol/L to prepare a high glucose-impaired HUVECs model. High glucose-impaired HUVECs were randomly divided into experimental and model groups, with the experimental group intervened with 100 μg/ml of MSC-Exos and the model group intervened with an equal volume of PBS solution, while a blank control group was also set up. Cell counting Kit-8 (CCK-8) cell proliferation assay, adhesion assay, matrigel tube formation assay and scratch assay were used to detect the effects of AS-IV-mediated MSC-Exos on the proliferation, adhesion, tube formation and migrationability of HUVECs; Western blot and real time fluorescence quantitative polymerase chain reaction (qRT-PCR) were used to detect the protein and mRNA expression of scorch death-related molecules, such as Caspase-1, GSDMD (Gasdermin D) and NLRP3 in each group.Results:The proliferation, adhesion number, tube number and migration width of HUVECs cells were significantly lower than those in the blank group ( P<0.05); The expression of Caspase-1, GSDMD, NLRP3 protein and their mRNA increased significantly ( P<0.001); Under the intervention of MSC-Exos mediated by AS-IV, the cell proliferation, adhesion number, tube number and migration width of HUVECs were significantly higher than those in the model group ( P<0.05); The expression of Caspase-1, GSDMD, NLRP3 protein and their mRNA decreased, with statistically significant difference ( P<0.05). Conclusions:AS-IV mediated MSC-Exos can significantly improve the biological function of high glucose-impaired endothelial cells, and its mechanism may be related to anti-pyroptosis.

Objective To observe the differential expression of high mobility group box - 1 protein (HMGB1) in renal tissues of heat stroke mice models, and to explore its role in the pathogenesis of heat stroke associated acute kidney injury(HS-associated AKI). Methods According to random number table, 20 healthy male C57BL/6J mice were randomly divided into 2 groups, including normal control (n=10) and heat stroke group (n=10). The mice in heat stroke group were given with a 2-hour-exposure in biological simulation chamber (temperature 41℃, humidity 70％). Heat stroke was defined as anal temperature lasting more than 40 degrees Celsius. A 18F - deoxyglucose nuclide labeled vivo imaging was conducted with micro - positron emission tomography(PET)/computer tomography (CT). Serum creatinine was examined with blood example. In order to evaluate the pathological changes, HE stain was conducted with kidney tissue, and mitochondrial morphological changes in kidney tissue were observed by transmission electron microscopy. The expressions of HMGB1 and apoptosis inducing factor mitochondria associated 2 (Aifm2) were examined by immunohistochemical method, and the levels of HMGB1 and RAGE were examined by Western blotting. The cell apoptosis of renal tissue was detected by terminal deoxynucleotidyl transferase -mediated dUTP - biotin nick end labeling assay (TUNEL). The metabolomics of kidney tissue in mice were detected by liquid chromatography - mass spectrometry (LC - MS), and the pathway enrichment analysis was carried out by KEEG database. Results (1) The body temperature of the mice in heat shock group was significantly higher than that in normal control group 45 min after model establishment (P＜0.05). The level of serum creatinine in heat shock group was significantly higher than that in normal control group (P＜0.05), and the levels of 18F - deoxyglucose increased in skeletal muscle and visceral tissue of the mice in heat - shock group. (2) HE staining showed hemorrhage in collecting duct and tubular endothelial cell swelling, and mitochondrial swelling and deformation were observed by transmission electron microscopy in kidney tissue of the heat shock group. (3) Immunohistochemical method showed that the levels of Aifm2 and HMGB1 in heat shock group were higher (P＜0.05). (4) Western blotting showed that the levels of HMGB1 and RAGE in heat shock group were higher than those in normal control group (P＜0.05). (5) TUNEL showed that the number of cells with positive stain in kidney tissue of the heat shock group was higher than that in normal control group (P＜0.05). (6) Between normal control group and heat shock group, 136 differential metabolites were detected in kidney tissues. After analysis by KEGG database, pathway abnormalities such as unsaturated fatty acid metabolism disorder may be associated with HS - associated AKI, and many differential metabolites such as adrenic acid may be important regulatory points in the pathogenesis. Conclusion Acute kidney injury is a common complication of heat shock. It may be related to the dysfunction of renal mitochondria and activation of apoptotic pathway caused by systemic hypercatabolism, which may be related to the disorder of unsaturated fatty acid metabolism and activation of HMGB1. Some differential metabolites may be of high value in HS- associated AKI studies.

Objective Retrospective study and report on cases of "symptomatic facet of residual bone mass" caused by percutaneous transforaminal endoscopic discectomy (PTED),to analysis of its causes and revision strategies.Methods Seven cases of "symptomatic facet of residual bone mass" after PTED were found in six medical centers from July 2015 to November 2017.Weintroduced the course of diagnosis and treatment,to analysis of the causes,clinical features and revision strategies of the rare complication.Results Seven patients came from different medical centers (2 cases in Ningbo No.6 Hospital and 1 case in each of the other medical centers).The average age of the subject is 67.29±9.64 years (range from 57-83 years).Among them there were 1 male and 6 female.PTED was performed for all cases with lumbar disc herniation or stenosis.The operative segments were 1 of L2,3,2 of L3,4,3 of L4,5,1 of L5S1.Symptoms occurred immediately after surgery in all cases except one after a week of operation and another one month later.Two cases were appeared symptom of contralateral irritation,and the rest were aggravated by the original symptoms.Two cerebrospinal fluid leakage caused by bone mass piercing the dural sac.The bone mass compressed the nerve root and caused 1 case of lower limb muscle weakness.Foraminoplasty was performed during PTED in all patients.After CT scan,5 cases of bone mass were found on the same side of operation,and 2 cases were in the contralateral side.The shortest time for revision was 2 days and the longest 3 months.After conservative treatment,the symptoms were relieved in only one case.Revision surgeries were performed for all the other 6 cases,2 with microendoscopic discectomy (MED),1 mobile microendoscopic discectomy (MMED),1 small incision operation,1 PTED and 1 with minimal invasive surgery of transforaminal lumbar intervertebral fusion (MIS-TLIF).The VAS scores of low back pain and leg pain was significantly relieved from 8.67±0.52 to 1.50±0.55.Conclusion FTED may lead to residual bone mass in lumbar foraminoplasty.The penetration of the bone mass block into the spinal canal can cause the compression symptoms of the corresponding segment.The patients showed the corresponding spinal canal stenosis and nerve root irritation symptoms.A revision operation is required to remove the oppressed bone mass to relieve the symptoms as soon as possible if the conservative treatment not effective.

Objective To observe the efficacy of oropharyngeal muscle exercise for relieving obstructive sleep apnea (OSAS) among stroke survivors.Methods Fifty stroke survivors with moderate OSAS were randomly divided into an observation group and a control group,each of 25.Both groups were given routine drugs and rehabilitation,while the observation group was additionally provided with oropharyngeal muscle exercises during the daytime for 20 minutes twice a day for6 weeks.The control group received deep breathing therapy.Before and after the 6 weeks of treatment,both groups were evaluated using polysomnography.Their sleep quality and daytime sleepiness were measured using the Pittsburgh sleep quality index and the Stanford sleepiness scale.Any changes in the patients' pharyngeal morphology after exercise were evaluated using MRI.Results After the oropharyngeal muscle exercises,the apnea hypoventilation index and minimum SaO2 ％,the snore index and sleep quality improved significantly.Daytime sleepiness was significantly relieved.Some structural remodeling of the pharyngeal airvay was observed by MRI,including significantly larger retropalatal distance and shorter length of the soft palate.The retropalatal distance was positively and correlated with the duration of exercise while the length of soft palate correlated negatively.Conclusion Exercising the oropharyngeal muscles is a promising alternative treatment for stroke survivors with moderate OSAS.It improves the morphology of the oropharynx to relieve obstruction during sleeping.

Objective To investigate the correlation between tumor-associated macrophages (TAMs) and the development of high risk human papilloma virus (hr-HPV)-related cervical cancer. Methods A total of 112 cases of cervical tissue were collected, including 16 normal cervical tissues, 55 cervical intraepithelial neoplasia (CIN) tissues and 41 squamous cervical cancer (SCC) tissues. The expression of CD163+ macrophages in the cervical tissues was detected by immunohistochemical method, and the results were analyzed in relation with the clinical data of the patients. Results Immunohistochemical analysis showed that the cell density of CD163+macrophages increased progressively with the increase in the tissue malignancy, in the order of normal cervical tissue, CIN I, CIN II-III, and SCC. Correlation analysis revealed a positive relationship between CD163 + macrophage density and tissue malignancy (P=0.000). The density of CD163 + macrophages was significantly upregulated in HR-HPV-positive SCC tissue (P<0.05). CD163+ macrophages were positively correlated with cervical lymph node metastasis (P=0.005) and FIGO stage (P=0.004) of SCC. Conclusion The expression of CD163+macrophages is positively correlated with malignant transformation of cervical tissues, and hr-HPV infection is significantly correlated with CD163 expression level in the macrophages. CD163+ macrophages can be used as predictors of the occurrence and progression of cervical cancer caused by hr-HPV infection.
