Objective: To analyze the relationship of gross motor skills and perceptual motor abilities with physical activity levels in preschool children in a Beijing kindergarten, so as to provide a reference for promoting the development of motor competence. Methods: From September 2018 to March 2021, preschoolers aged 4-5 years were selected using convenience sampling method from an urban kindergarten in Beijing. The Test of Gross Motor Development-Third Version(TGMD-3) was used to assess basic preschoolers s gross motor skills ( n =152). The Pictorial Scale of Perceived Movement Skill Competence(PMSC) was used to evaluate perceptual motor skills ( n =151). Accelerometers (Actigraph GT3X) were used to record physical activity levels ( n =52). Data were analyzed using one way analysis of variance (ANOVA) and Pearson correlation coefficients. Results: The mean scores for gross motor skills and perceptual motor abilities were (38.76±13.48) and (35.49±6.50), respectively. The moderate to vigorous physical activity(MVPA) level was(52.60±27.44) minutes per day. No statistically significant correlations were found between gross motor skills, perceptual motor abilities MVPA among boys, girls or the overall group ( r =-0.20 to 0.25, all P >0.05). However, Boys locomotor skills, overall children s locomotor skills, and boys gross motor skills were all positively correlated with MVPA( r =0.34-0.45, all P <0.05). Conclusion There is a correlation between locomotor skills and physical activity levels in 4 to 5-year-old children.

ObjectiveTo analyze the epidemiological and clinical characteristics of the 21 confirmed monkeypox cases in a district of Chengdu City, and to provide scientific guidance for the prevention and control of subsequent monkeypox epidemics. MethodsData of confirmed monkeypox cases residing in this district were collected from the Disease Control and Prevention Information System of China. A retrospective descriptive epidemiological analysis was used to analyze the demographic, distributional and behavioral characteristics of the cases. ResultsThe first confirmed case of monkeypox was reported on July 5, 2023. Up to April 30, 2025, a total of 21 confirmed cases of monkeypox have been reported. All cases were male, with a mean age of (30.9±6.2) years. The highest proportion of cases(47.62%) was in the 30‒40 years age group. The majority were men who have sex with men (MSM) population (90.48%, 19/21). The results showed that 19.05% of cases were co-infected with HIV, and 19.05% had a history of syphilis infection. Within 21 days prior to symptom onset, 19 cases (90.48%) self-reported engaging in male-to-male sexual contact, among whom 10 cases (52.63%) reported having taken protective measures, while 9 cases (47.37%) did not take safety precautions. Thirteen cases (61.90%) had no travel history to areas with reported monkeypox cases during the 21 days before symptom onset. The predominant manifestation was exanthem (100%, 21/21), followed by fever (57.14%, 12/21) and lymphadenectasis (47.62%, 10/21). Among febrile cases, 50.00% (6/12) had low-grade fever (37.3‒38.0 ℃). All cases were identified through active medical consultation. The median interval from symptom onset to the first medical visit was 3 (2, 6) days, with a maximum interval of 14 days. The median interval from symptom onset to laboratory confirmation was 7 (5, 9) days. Six cases (28.57%) had two or more visits to the hospital, with bacterial infection being the primary initial diagnosis. ConclusionMonkeypox prevention and control efforts in a district of Chengdu City should prioritize MSM population and young and middle-aged adults aged 30 to <40 years. It is recommended to establish an integrated monkeypox epidemic prevention and control network by leveraging existing HIV/AIDS prevention and control network. Concurrently, accelerating the deployment of the national intelligent infectious disease monitoring and early warning front-end software will strengthen early detection capabilities and be beneficial for the overall effectiveness of epidemic prevention and control efforts.

ObjectiveTo investigate the pharmacological basis and mechanism of Qinlian Jiangxia decoction （QLJXD） in the treatment of glucose and lipid metabolism disorders. MethodsThe Encyclopedia of Traditional Chinese Medicine （ETCM） and the GeneCards database were used to predict the active components and targets of QLJXD in the treatment of type 2 diabetes mellitus （T2DM） combined with dyslipidemia. The key components and core targets were screened following protein-protein interaction （PPI） network， Gene Ontology （GO）， and Kyoto Encyclopedia of Genes and Genomes （KEGG） analyses of the targets and then verified by molecular docking. SD rats were used to prepare the QLJXD-medicated serum， and a 3T3-L1 adipocyte model of insulin resistance （IR） was constructed with 1 μmol·L^-1 dexamethasone （DEX）. After intervention with four sera， cell glucose consumption and lipid metabolism levels were measured to screen the optimal action concentration of the medicated serum. A 3T3-L1 adipocyte model of IR with fatty acid-binding protein 4 （FABP4） overexpression was further constructed by plasmid transfection. Western blot and Real-time quantitative PCR （Real-time PCR） were employed to determine the expression of FABP4 and peroxisome proliferator-activated receptor γ （PPARG） at protein and mRNA levels， respectively， on the basis of which the regulatory effect of QLJXD on the FABP4/PPARG pathway was evaluated. ResultsNetwork pharmacology revealed that the key active components of QLJXD in treating T2DM complicated with dyslipidemia were baicalein， acacetin， and α-linolenic acid， and FABP1， FABP4， and PPARG were the core targets. Molecular docking showed good binding activity between the key components and core targets. QLJXD-medicated serum improved the glucose uptake capacity， increased insulin （INS）-stimulated glucose consumption （P<0.01）， and reduced total cholesterol （TC）， triglyceride （TG）， and free fatty acid （FFA） levels （P<0.01） in the 3T3-L1 adipocyte model of IR， with the medium-dose-medicated serum demonstrating the most potent effects. Overexpression of FABP4 impaired the glucose uptake capacity in the 3T3-L1 adipocyte model of IR and promoted intracellular accumulation of TC， TG， and FFA （P<0.05）. The medium-dose-medicated serum improved glucose uptake capacity and reduced the accumulation of TC， TG， and FFA （P<0.01）， while decreasing the protein and mRNA expression levels of FABP4 and concomitantly increasing the protein and mRNA levels of PPARG （P<0.05） in the 3T3-L1 adipocyte model of IR with FABP4 overexpression. ConclusionThe QLJXD-medicated serum has been evidenced to ameliorate glucose and lipid metabolism disorders in the 3T3-L1 adipocyte model of IR through multiple components， with the mechanism related to the FABP4/PPARG signaling pathway.

Objective: To explore the plasma metabonomic characteristics of patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome. Methods: One hundred and three patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome were enrolled from November 2023 to February 2024 in the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and 54 healthy individuals were recruited. The general data of the two groups were analyzed, and the plasma metabolite content was detected using ultra-high performance liquid chromatography-Orbitrap mass spectrometry. Construct an orthogonal partial least squares discriminant analysis model to screen metabolites with significant intergroup changes. The variable importance in projection≥ 1, |log2FC|>1, and P<0.05 were used as the criteria for the screening of differential metabolites. Annotate differential metabolites using internal databases and the human metabolome database, and perform pathway analysis using MetaboAnalyst website. Results: There was no statistically significant difference in gender and age between the two groups.Seventeen potential differential metabolites were identified. The D-4′-phosphopantothenate, 2, 6-dichloroindophenol, 4-methylphenol, hypoxanthine, 11, 12-epoxyeicosatrienoic acids, oleamide, 3-phenyllactic acid contents were higher in patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome than in healthy individuals(P<0.05); 3-anisic acid, 3-iodo-octadecanoic acid, mebendazole, β-alanine, citric acid, trans-aconitic acid, geranyl diphosphate, lysophosphatidylcholine(18∶2), phosphatidylethanolamine(18∶1), and caprolactam contents were lower in patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome than in healthy individuals(P<0.05). Ten metabolic pathways were identified, including the key metabolic pantothenate and coenzyme A biosynthesis pathways. Conclusion Metabolic differences were observed between patients with type 2 diabetes mellitus and turbid toxin accumulation syndrome and healthy individuals, and the underlying mechanism may involve the pantothenate and coenzyme A biosynthesis pathways, jointly mediated by D-4′-phosphopantothenate and β-alanine.

Background and aims:Studies indicate that the gut microbiota and its metabolites are involved in the progression of cardiovascular diseases,and enterohepatic circulation plays an important role in this progression.This study aims to identify potential probiotics for the treatment of unstable angina(UA)and elucidate their mechanisms of action.Methods:Initially,the gut microbiota from patients with UA and control was analyzed.To directly assess the effects of Bifidobacterium supplementation,10 patients with UA were enrolled and administered Bifidobacterium(630 mg per intake twice a day for 1 month).The fecal metagenome,serum trimethyl-amine N-oxide(TMAO)levels,and other laboratory parameters were evaluated before and after Bifido-bacterium supplementation.Results:After supplementing with Bifidobacterium for 1 month,there were statistically significant dif-ferences(P＜0.05)in TMAO,aspartate aminotransferase,total cholesterol,and low-density lipoprotein compared to before.Additionally,the abundance of Bifidobacterium longum increased significantly,although the overall abundance of Bifidobacterium did not reach statistical significance.The gut micro-biota,metabolites,and gut-liver axis are involved in the progression of UA,and potential mechanisms should be further studied.Conclusions:Metagenomic analysis demonstrated a reduced abundance of Bifidobacterium in patients with UA.Supplementation with Bifidobacterium restored gut dysbiosis and decreased circulating TMAO levels in patients with UA.This study provides evidence that Bifidobacterium may exert cardiovascular-protective effects through the gut-liver-heart axis.

Autoimmune disease is a kind of disease characterized by immune imbalance,abnormal activation of immune cells,massive production of inflammatory factors and immune complexes,which leads to the damage of multiple organs and systems.Autoimmune disease is easy to recur in clinical practice.The previous studies showed that there is a correlation between dampness syndrome in traditional Chinese medicine(TCM)and immune dysfunction.This paper explains the theoretical basis for the correlation between dampness syndrome of TCM and the recurrence of autoimmune diseases,and the similarities between the two in macro appearance,pathogenesis characteristics,etc.,analyzes the possible correlation about biological mechanism between dampness syndrome and autoimmune diseases,and discussed the correlation between pathogenic dampness of TCM and the recurrence of autoimmune diseases such as psoriasis,rheumatoid arthritis,ulcerative colitis,and nephrotic syndrome.It is pointed out that pathogenic dampness of TCM is an important pathogenic factor for the recurrence of autoimmune diseases,and is closely related to the recurrence of autoimmune diseases.Autoimmune diseases can be treated from the perspective of pathogenic dampness in TCM,and therapy of invigorating spleen,replenishing qi and removing dampness is frequently adopted,which is beneficial to alleviating the clinical symptoms of patients and reducing the recurrence of autoimmune disease.

Objective To explore the mechanism by which Wandai Decoction prevents and treats vulvovaginal candidiasis(VVC)of the spleen deficiency and excessive dampness type and restores the vaginal flora structure,and to identify the potential metabolic pathways involved using metagenomics and metabolomics.Methods Twenty VVC patients who met the inclusion criteria were randomly assigned to a Wandai Decoction group and a fluconazole group(n=10 in each group).Subjects in the fluconazole group were given a single oral dose of 150 mg fluconazole,while those in the Wandai Decoction group took the Wandai Decoction orally for 14 days.The vulvovaginal signs and symptoms(VSS)scores of both patient groups were evaluated before and after treatment.Vaginal secretions were collected before and after treatment.The Illumina sequencing and the liquid chromatography with tandem mass spectrometry(LC-MS/MS)platform were used to conduct metagenomic and metabolomics analyses of the vaginal secretions,respectively.Results The VSS score results showed that the VSS scores of both groups decreased after treatment compared with those before treatment(P＜0.01),and there was no statistically significant difference in the VSS scores between the two groups after treatment.Metagenomics results showed that,after treatment,the vaginal microbial communities in the Wandai Decoction group were of CST Ⅱ and Ⅴ types(predominated by Lactobacillus gasseri and Lactobacillus jensenii),while those in the fluconazole group were Lactobacillus_intestinalis and Streptococcus_sp._oral_taxon_431.KEGG functional enrichment analysis results showed that,in terms of the cell cycle and meiosis functions of Candida albicans,statistically significant differences between the Wandai Decoction and fluconazole groups were observed(P＜0.05).Metabolomic analysis identified 120 differential metabolites between the two groups after treatment.The results of KEGG metabolic pathway enrichment analysis of differential metabolites showed that the Wandai Decoction might be significantly superior to fluconazole in improving local vaginal metabolic pathways of α-linolenic acid,glycerophospholipid metabolism,pentose and glucuronic acid interconversion,and arachidonic acid.Conclusion The Wandai Decoction can improve the vaginal flora of VVC patients.It may be superior to fluconazole in the signaling pathways of the cell cycle and meiosis.The improvement of the vaginal flora by the Wandai Decoction may be associated with its effect on metabolic pathways of glycerophospholipid metabolism,pentose and glucuronic acid interconversion,and others in the vagina.

Objective To investigate the effects of curcumin on the proliferation,migration,invasion,and apoptosis of pheochromocytomacell line PC12.Methods PC12 cells were incubated with different concentrations of curcumin.Cell proliferation was assessed using the CCK-8 assay to determine the IC50.The scratch assay was used to evaluate cell migration and Transwell chambers were employed to assess cell invasiveness.Flow cytometry was used to analyze apoptosis.qPCR was conducted to measure the mRNA expression of pro-apoptotic(Bax)and anti-apoptotic(Bcl-2)genes,and Western blot was performed to detect Bax and Bcl-2 protein expressions.Results Curcumin(10-80 μmol/L)inhibited PC12 cell proliferation in a concentration-dependent manner,with an IC50 as 29 μmol/L.Curcumin also suppressed PC12 cell migration in a concentration-dependent mode;the migration rate decreased from 66％in the control group down to 51％,5％,and 0.5％in the 10,20,and 30 μmol/L curcumin groups,respectively.Curcumin at concentrations of 20-30 μmol/L significantly reduced PC12 cell invasiveness(P<0.000 1).Moreover,curcumin significantly promoted PC12 cell apoptosis;the percentage of apoptotic cells increased by 2.25％,18.53％,and 26.89％in the 10,20,and 30 μmol/L curcumin groups as compared to those of control group,respectively.Curcumin treatment resulted in a significant up-regulation of Bax mRNA and protein expression,and a significant down-regulation of Bcl-2 mRNA and protein expression(P<0.05).Conclusions Curcumin may significantly inhibit the proliferation,migration,and invasion of PC12 cells and arouse cell apopto-sis.Its pro-apoptotic effect may be associated with alterations in the expression of Bax and Bcl-2 genes.

Objective:To investigate the value of gadoxetate disodium-enhanced MRI combined with T 1 mapping in preoperative prediction of cytokeratin 19 (CK19) and glypican-3 (GPC3) positive dual-phenotype hepatocellular carcinoma (DPHCC). Methods:This case-control study included retrospectively enrolled patients with pathologically confirmed HCC from Central People′s Hospital of Zhanjiang (training set, n=85; December 2020 to July 2022) and the Second Affiliated Hospital, School of Medicine, South China University of Technology (test set, n=35; April 2023 to April 2024). Patients were categorized into CK19 and GPC3 positive DPHCC group (training set=19, test set=11) and non-DPHCC group (training set=66, test set=24) based on postoperative immunohistochemical staining. All patients received preoperative MRI scans, including gadoxetate disodium-enhanced imaging and T 1 mapping. Clinical data were collected, qualitative MRI features were evaluated, and quantitative parameters were measured, including signal intensity, T 1 values, apparent diffusion coefficient (ADC), tumor-to-liver ADC ratio (rADC), tumor-to-liver signal intensity ratio, and T 1 relaxation time reduction rate (ΔT 1%). Statistical comparisons between groups were performed using independent t-tests, Mann-Whitney U tests, or χ2 tests. Multivariate logistic regression identified independent predictors of CK19 and GPC3 positive DPHCC, and a combined model was constructed. Predictive performance was evaluated using area under the receiver operating characteristic curve (AUC), with DeLong test comparing model performance. Results:Significant intergroup differences were observed in alpha-fetoprotein (AFP), total bilirubin, direct bilirubin, DWI target sign, rADC, hepatobiliary-phase T 1 (T 1HBP), and ΔT 1% ( P<0.05). Multivariate analysis identified AFP>20 ng/ml ( OR=5.835, 95% CI 1.019-33.397, P=0.048), DWI target sign ( OR=13.408, 95% CI 2.216-81.131, P=0.005), and ΔT1%≤31% ( OR=14.429, 95% CI 2.166-96.125, P=0.006) as independent predictors of DPHCC. The AUC values of the aforementioned three independent predictors and the combined model for predicting DPHCC were 0.641 (95% CI 0.530-0.742), 0.679 (95% CI 0.569-0.777), 0.740 (95% CI 0.634-0.829), and 0.886 (95% CI 0.799-0.945) in the training set, and 0.568 (95% CI 0.390-0.743), 0.669 (95% CI 0.490-0.818), 0.689 (95% CI 0.511-0.843), and 0.824 (95% CI 0.658-0.931) in the test set, respectively. The DeLong test results showed that in the training set, the diagnostic performance of the combined model was superior to those of the three individual features ( Z=3.68, P<0.001; Z=3.15, P=0.002; Z=3.15, P=0.002). In the test cohort, the combined model demonstrated better diagnostic performance than AFP>20 ng/ml and ΔT 1%≤31% ( Z=2.15, P=0.032; Z=2.12, P=0.034), while no statistically significant difference was observed compared with the DWI target sign ( Z=1.77, P=0.076). Conclusion:The integrated model incorporating clinical data, gadoxetate disodium-enhanced MRI, and T 1 mapping parameters effectively predicts CK19 and GPC3 positive DPHCC.
