This study aims to explore whether Guzheng playing training has a positive impact on the brain functional state of children with Autism Spectrum Disorder (ASD) based on power spectral and sample entropy analyses. Eight ASD participants were selected to undergo four months of Guzheng playing training, with one month as a training cycle. Electroencephalogram (EEG) signals and behavioral data were collected for comparative analysis. The results showed that after Guzheng playing training, the relative power of the alpha band in the occipital lobe of ASD children increased, and the relative power of the theta band in the parietal lobe decreased. The differences compared with typically developing (TD) children were narrowed. Moreover, some channels exhibited a gradual increase or decrease in power with the extended training period. Meanwhile, the sample entropy parameter also showed a similar upward trend, which was consistent with the behavioral data representation. The study shows that Guzheng training can enhance the brain function of ASD patients, with better effects from longer training. Guzheng playing training could be used as a daily intervention for autism.

Objective To explore the predictive value of thromboelastography(TEG)combined with ser-um D-dimer(D-D)and total bilirubin(TBIL)in the risk of postoperative deep vein thrombosis(DVT)in pa-tients with hip fracture.Methods A total of 120 patients with hip fracture who underwent surgical treatment in this hospital from January 2022 to January 2024 were retrospectively selected.According to the occurrence of postoperative DVT,the patients were divided into DVT group(n=34)and non-DVT group(n=86).The TEG parameters[coagulation reaction time(R),blood clot formation time(K),α angle and maximum ampli-tude of thrombus(MA)],D-D and TBIL levels were compared between the two groups before operation.Mul-tivariate Logistic regression was used to analyze the influencing factors of postoperative DVT in patients with hip fracture.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of TBIL,D-D and TEG parameters for postoperative DVT in patients with hip fracture.Results Compared with the non-DVT group,the TBIL level,R value and K value in the DVT group were significantly decreased,while the D-D level,α angle and MA value were significantly increased(P＜0.05).Multivariate Logistic regression anal-ysis showed that TBIL,D-D and TEG parameters were the influencing factors of postoperative DVT in pa-tients with hip fracture(P＜0.05).ROC curve results showed that the area under the curve of TBIL,D-D,TEG parameters combined to predict postoperative DVT in patients with hip fracture was 0.940,the sensitivi-ty was 82.4％,and the specificity was 93.0％.Conclusion TEG combined with D-D and TBIL levels have a high predictive value in postoperative DVT in patients with hip fracture,which can be used in the early evalua-tion of postoperative DVT in patients with hip fracture,and help to improve the prognosis of patients.

Objective To investigate lymphocyte interstitial infiltration condition and the changes of immune checkpoint gene expression in different stages of early esophageal cancer.Methods A ret-rospective analysis was conducted on the clinical data of 90 patients with early esophageal cancer.Based on the pathological depth of infiltration,they were divided into three types:T1a-M1,T1a-M2,and T1a-M3,with 30 cases in each type.Additionally,30 cases of paired normal mucosa tissues adja-cent to the cancer were selected.Hematoxylin-eosin(HE)staining was used to observe tissue morpholo-gy.Immunohistochemistry was employed to detect the expression of CD3,CD4,CD8,and CD20.Real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)was applied to measure the mRNA expression levels of immune checkpoint genes[programmed death ligand-1(PD-L1),cytotoxic T-lym-phocyte-associated protein 4(CTLA4),T-cell immunoglobulin and mucin domain-3(TIM-3),lympho-cyte activation gene 3(LAG3),programmed death receptor-1(PD-1),programmed death ligand-2(PD-L2),and T-cell immunoreceptor with Ig and ITIM domains protein(TIGIT)].Results As the stage of early esophageal cancer progressed,the ratio of tumor cells to lymphocytes increased.The number of CD3+T cells was greater than that of CD20+B cells,and the proportion of CD4+T cells among total T cells was higher than that of CD8+T cells(P＜0.001).The mRNA expression levels of gene in immune checkpoints in patients were elevated(P＜0.05).Compared with normal adja-cent tissues,the expression levels of PD-L1 mRNA,CTLA4 mRNA,TIM-3 mRNA,PD-1 mRNA,and TIGIT mRNA were elevated in patients with T1a-M1,T1a-M2,and T1a-M3 types(P＜0.05).Compared with normal adjacent tissues,the expression levels of LAG3 mRNA and PD-L2 mRNA were increased in patients with T1a-M2 and T1a-M3 types(P＜0.05).Conclusion The progres-sion of early esophageal cancer staging is correlated with increased immune checkpoint gene expres-sion and a decreased lymphocyte ratio,suggesting that changes in the immune microenvironment may be involved in tumor progression.

Objective To explore the risk factors of cardiomyopathy in patients with diabetes and their correlations with the levels of serum fork head box protein O1(FOXO1),growth differentiation factor 11(GDF11),and matrix metalloproteinase-3(MMP3).Methods 200 patients with diabetes complicated with cardiomyopathy and 200 patients with simple diabetes admitted to the People's Hospital of Xinjiang Uygur Autonomous Region from September 2023 to April 2025 were selected to detect serum FOXO1,GDF11 and MMP3 levels,analyze their correlation with cardiac function parameters,screen risk factors through multifactor logistic regression,construct a nomogram model and a receiver operating characteristic(ROC)curve,and evaluate the diagnostic value.Results The duration of diabetes cardiomyopathy group≥10 years,the expression rate of reactive oxygen species(ROS)≥90%,the insulin resistance index and the levels of FOXO1 and MMP3 were significantly higher than those in the simple diabetes group(P<0.05),and the level of GDF11 was lower than that in the simple diabetes group(P<0.05).FOXO1 and MMP3 were positively correlated with E/e'and negatively correlated with LVEF and E/A;GDF11 was negatively correlated with E/e'and positively correlated with LVEF and E/A(P<0.05).The nomogram model showed that the weights of the influencing factors were GDF11,FOXO1,insulin resistance index,MMP3,ROS expression rate,and the course of diabetes.The model calibration was good(χ2=7.336,P=0.719).The combined diagnostic AUC of FOXO1,GDF11,and MMP3 was 0.950,which was better than that of a single indicator(P<0.05).Conclusion GDF11,FOXO1,Insulin resistance index,MMP3,ROS expression rate and the course of diabetes are risk factors for diabetes cardiomyopathy,and the combination of the three is of high diagnostic value.

Objective To analyze the verification results of national laboratories involved in urinary sodium and potassium monitoring. Methods A total of 416 blinded verification samples from 32 monitoring laboratories, which participated in the national 24-hour urinary sodium and potassium detection verification comparison program in 2023 and 2024, were included as the study subjects. These samples were reanalyzed by both the monitoring laboratories and a reference laboratory using the ion-selective electrode method. Results The overall qualification rates for the 32 laboratories were 84.3% (182/216) in 2023 and 82.0% (164/200) in 2024, with 62.5% (20/32) achieving qualified results for two consecutive years. In 2023, centers for disease control and prevention (CDC) laboratories had higher qualification rates than the third-party laboratories for both 24-hour urinary sodium and potassium (95.2% vs 78.8%, 95.2% vs 75.8%, both P<0.05). This difference was not significant in 2024 (87.8% vs 78.0%, 90.2% vs 76.3%, both P>0.05). There was no significant difference in median absolute relative deviation of urinary sodium results from monitoring laboratories between 2023 and 2024 (2.7% vs 2.1%, P>0.05), whereas the median absolute relative deviation of urinary potassium results in 2024 was lower than that in 2023 (3.4% vs 8.4%, P<0.01). Conclusion The detection accuracy of national laboratories for urinary sodium and potassium monitoring shows an overall improving trend, with the accuracy of potassium measurement showing particular enhancement. There is no significant difference in the detection qualification rates between laboratories of the CDC and the third-party laboratories, suggesting that a sustained verification feedback mechanism is key to driving quality improvement.

Objective:To develop a prediction model using machine learning to identify anxiety and depression in elderly individuals.Methods:This study collected data from 15079 elderly individuals in Shanxi Province, including their social demographic factors and disease status.Anxiety and depression were evaluated using GAD-7 and PHQ-9 scales to understand the characteristics of mental illness in the elderly.The evaluation indexes included accuracy, recall, precision, F1 score, Receiver Operating Characteristic Curve(ROC), and area under the curve(AUC), which were derived from the confusion matrix and several models.Results:The output of our study clearly demonstrates that the full feature prediction based on LightGBM is highly accurate, with an AUC of 0.805[95% CI: 0.794-0.811]. This outperforms the Random Forest model, which achieved an AUC of 0.730[95% CI: 0.702-0.741], and the XGboost model, which achieved an AUC of 0.802[95% CI: 0.780-0.807]. Therefore, LightGBM algorithm proves to be a strong prediction model.Our simplified model, based on eight selected features, also achieves a respectable AUC of approximately 0.75. Conclusions:The new prediction model for anxiety and depression specifically designed for the elderly can be effectively utilized in grassroots health surveys or for self-examinations to efficiently predict anxiety and depression levels among the elderly population in the community.
