Objective: To explore the relationship between sleep quality and executive function among middle school students, so as to provide theoretical support for the promotion of adolescents physical and mental health development. Methods: From September to December 2023, 5 713 junior and senior high school students aged 13 to 18 were selected by stratified cluster random sampling method from Shanghai, Suzhou, Taiyuan, Wuyuan, Xingyi, and Urumqi. Pittsburgh Sleep Quality Index was used to conduct sleep quality survey. And conduct executive function was tested on middle school students, including inhibitory function, refresh function and conversion function tests. Spearman correlation and linear regression were used to analyze the relationship between sleep quality and executive function of middle school students. Results: The total Pittsburgh Sleep Quality Index (PSQI) score of boys was [4.0(2.0,6.0)] and that of girls was [5.0(3.0,6.0)], and the difference was statistically significant ( Z=-10.90, P < 0.01 ). The total PSQI score of boys was positively correlated with both 2-back reaction time and conversion function of executive function ( r =0.04, 0.04); the total PSQI score of girls was negatively correlated with 2-back reaction time ( r =-0.04) ( P <0.05). After controlling for variables such as mental health, physical activity and nutritional status,linear regression analyses showed that PSQI total score of middle school students was positively correlated with the inhibitory function and the conversion function response time [ B (95% CI )=1.28(0.21-2.34), 7.62(2.34-12.90), P <0.05]; the associations of total PSQI scores among middle school students with both 2-back and 1-back response time were not statistically significant [ B (95% CI )=-5.88(-16.14-4.37), 8.05( -3.39 -19.50), P >0.05]. Conclusion Positive correlations are observed on sleep quality with inhibitory and conversion functions of executive function among middle school students.

Objective To investigate T cell subtypes and their functions in liver immune microenvironments among patients with alveolar echinococcosis (AE) using single-cell RNA sequencing (scRNA-seq). Methods Four AE patients that were admitted to Qinghai Provincial People’s Hospital in 2023 for hepatic surgery for the first time were enrolled, and liver specimens were sampled 1 cm (peri-lesion, PL group) and > 5 cm from AE lesions (distal lesion, DL group) among each patient. Finally, a total of eight liver specimens were sampled from four AE patients for scRNA-seq analysis. Genome and transcriptome data of liver specimens were processed using the software Cell Ranger and R package. Differentially expressed genes (DEGs) and their biological functions were analyzed using gene ontology (GO) enrichment analysis and Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis, and the primary intercellular communication patterns and interaction mechanisms were identified among T cell subtypes in liver specimens using the CellChat package. In addition, the developmental stages of T cells were subjected to trajectory analysis with the monocle package to investigate the expression of genes associated with cell growth and tumor transformation, and to predict the developmental trajectories of T cells. Results All four AE patients were female, with a mean age of (25.00 ± 9.06) years, and there were three cases from Jiuzhi County, Golog Tibetan Autonomous Prefecture and one case from Chengduo County, Yushu Tibetan Autonomous Prefecture, Qinghai Province. The viability of single-cell samples from eight liver specimens was 90.41% to 96.33%, and a total of 81 763 cells were analyzed, with 19 cell types annotated. Of these cell types, 13 were immune cells (87.60%), and T cells (33.13%), neutrophils (15.40%), and natural killer cells (11.92%) were the three most common cell types. Re-clustering of 27 752 T cells and proliferative T cells identified 10 distinct T cell subtypes, with CD8⁺ cytotoxic T cells (23.43%), CD8⁺ naive T cells (12.80%), and CD4⁺ effector memory T cells (17.73%) as dominant cell types. The proportions of T helper 2 (Th2) cells (5.19% vs. 3.63%; χ² = 38.35, P < 0.01) and CD4⁺ effector memory T cells (21.59% vs. 13.67%; χ² = 244.70, P < 0.01) were significantly higher in liver specimens in the PL group than in the DL group, and the proportion of CD4⁺ helper T cells was significantly lower in the PL group than in the DL group (7.50% vs. 14.75%; χ² = 330.52, P < 0.01). KEGG pathway analysis revealed that Th2 cells were significantly enriched in cell apoptosis and multiple cancer-associated pathways, and CD4⁺ effector memory T cells were significantly enriched in the regulation of cytokines and chronic inflammation, while CD4⁺ helper T cells were significantly enriched in immune responses regulation. Trajectory analysis of T cells showed that CD4⁺ helper T cells were at an earlier developmental stage relative to Th2 cells and CD4⁺ effector memory T cells, and the expression of inhibitor of DNA binding 3 (ID3), thioredoxin interacting protein (TXNIP), Bcl2-associated athanogene 3 (BAG3) and heat shock protein family B (small) member 1 (HSPB1) genes appeared a tendency towards a decline over time. Conclusions CD4⁺ effector memory T cells and CD8⁺ cytotoxic T cells are primary interacting cells in the liver specimens of AE patients. Reduced expression of Th2 cells and CD4⁺ helper T cells contributes to an inhibitory immune microenvironment, which promotes immune evasion by Echinococcus multilocularis, and Th2 cells are significantly enriched in multiple cancer-associated pathways, which may be linked to the invasive growth of E. multilocularis.

The idiopathic inflammatory myopathies encompass a diverse array of autoimmune diseases,characterized by muscular inflammation and various extramuscular manifestations.These conditions have the poten-tial to impact multiple organs,including the lungs,skin,joints,gastrointestinal tract,and heart.The defining features of these conditions are muscle weakness and myalgia.Although cardiac involvement is infrequent,its clinical manifestations are subtle and easily overlooked.Cardiac damage represents a significant contributor to mortality and morbidity in patients with idiopathic inflammatory myopathy.Early and accurate identification of cardiac involve-ment may facilitate improved patient outcomes.This article provides an overview of the potential etiology,clinical presentations,risk factors,biomarkers,and imaging studies for early diagnosis of cardiac involvement in idio-pathic inflammatory myopathy.This review aims to enhance clinicians'understanding and diagnostic capabilities re-garding cardiac involvement in idiopathic inflammatory myopathy while promoting early intervention strategies for lifelong management and improved prognosis.

Based on the Delphi method, combined with the results of the previous literature study and expert interviews, 3 rounds of expert consultation were conducted to evaluate the degree of concentration of expert opinions and their importance from 3 aspects: arithmetic mean, full score ratio ( Ki), and rank sum ( Si), to construct a diagnostic scale for rheumatoid arthritis (RA) cold-dampness syndrome. In this study, 30 expert questionnaires were distributed in the 1st round, 30 questionnaires were recovered, and the expert coordination coefficient was 0.309; 30 expert questionnaires were distributed in the 2nd round, 30 questionnaires were recovered, and the expert coordination coefficient was 0.320; and 30 expert questionnaires were distributed in the 3rd round, 29 questionnaires were recovered, and the expert coordination coefficient was 0.387. The maximum value of the coefficient of variation of the experts of the 3 rounds was 0.27, and the minimum value was 0.09, suggesting that the consistency and credibility of the experts' evaluation of the importance of the entries of cold-dampness syndrome were high. In this study, the mean values and weights of 17 entries were finally obtained, of which the top 5 entries were cold pain in joints (4.793, 0.066 6); aggravated by cold (4.586, 0.063 7); white tongue coating (4.552, 0.063 2); aggravated in cloudy and rainy days (4.448, 0.061 8); and painful joints that are not warm to the touch (4.379, 0.060 8). This study completed the screening of relevant entries and conducted preliminary discussions, laying the foundation for constructing a diagnostic scale for RA cold-dampness syndrome and forming the final diagnostic criteria. The research method is scientific and reliable, which can provide reference for the diagnostic standard of RA cold-dampness syndrome, but further clinical practice research is still needed.

Background and purpose:Esophageal carcinoma(ESCA)is one of the malignant tumors with high mortality rate,and the underlying mechanism of its development is largely unknown.CDC20 plays an important role in tumorigenesis,and its dysregulated expression is closely related to tumor occurrence and development.The expression of CDC20 is increased in a variety of tumors,and knocking down CDC20 can inhibit tumor cell proliferation.NLRP3 is the main component of the inflammasome,and inflammasome is also closely related to tumor occurrence and development.Here,our study aimed to investigate whether CDC20 promotes the proliferation of ESCA cells through NLRP3 and its regulatory mechanism.Methods:The expression levels of CDC20 and NLRP3 genes in ESCA patients were analyzed using The Cancer Genome Atlas(TCGA)detabase and GTEx public database.We collected clinical and pathological data and tissues from 80 ESCA patients at the First Affiliated Hospital of Xinxiang Medical College,and detected the protein expression of NLRP3 in ESCA patients through immunohistochemistry staining.This study was approved by the Ethics Committee of the First Affiliated Hospital of Xinxiang Medical College(Number:EC-021-137).We studied the effects of knocking down CDC20 and NLRP3 gene on the proliferation ability of esophageal squamous cell carcinoma cells EC9706 and KYSE150 using short hairpin RNA(shRNA)technology.Co-immunoprecipitation(Co-IP),proteasome inhibitors and ubiquitination experiments were used to detect whether CDC20 interacts with NLRP3,and to elucidate whether CDC20 regulates NLRP3 expression through the ubiquitination pathway.This study was approved by the Ethics Committee of the First Affiliated Hospital of Xinxiang Medical College(Number:EC-021-137).Results:The TCGA database analysis showed that the expression levels of CDC20 and NLRP3 mRNA were significantly higher in the cancer tissues of ESCA patients than in the adjacent tissues.The immunohistochemistry results further showed that compared with adjacent tissues,the protein expression levels of CDC20 and NLRP3 were increased in ESCA tissues.Knocking down CDC20 and NLRP3 genes inhibited the proliferation of ESCA cells.Co-IP,proteasome inhibitors and ubiquitination experiments confirmed that CDC20 interacted with NLRP3 through its leucine-rich repeat(LRR),and CDC20 stabilized its expression by promoting NLRP3 ubiquitination.Conclusion:CDC20 and NLRP3 are upregulated in ESCA tissues,and CDC20 stabilizes their expression through ubiquitination of NLRP3,promoting ESCA cell proliferation.This suggests that CDC20 and NLRP3 may be potential diagnostic targets for ESCA.

OBJECTIVE: To investigate the clinical and genetic characteristics of a patient with STISS syndrome due to variant of PSMD12 gene. METHODS: Clinical data and result of genetic testing of a patient who was admitted to Shanghai Children's Medical Center, Shanghai Jiaotong University School of Medicine on October 4, 2020 were analyzed, together with a review of relevant literature. RESULTS: The patient was found to harbor a heterozygous c.601C>T (p.Arg201*) nonsense variant of the PSMD12 gene, which was unreported previously. Clinically, the height of the patient has differed significantly from reported in the literature. An extremely rare case of STISS syndrome due to variant of the PSMD12 gene has been diagnosed. CONCLUSION Whether the severely short stature is part of the clinical spectrum for PSMD12 gene variants needs to be further explored, and the efficacy and safety of growth hormone therapy has yet to be determined.

Objective:To investigate the risk factor of hepatocellular carcinoma (HCC) with vessels encapsulating tumor clusters (VETC) and the application value of its risk scoring model.Methods:The retrospective cross-sectional study was conducted. The clinicopathological data of 149 patients with HCC who were admitted to two medical centers, including 97 cases in the Jiangnan University Medical Center and 52 cases in the Affiliated Xingtai People′s Hospital of Hebei Medical University, from January 2017 to April 2020 were collected. There were 116 males and 33 females, aged (58±12)years. There were 74 cases with VETC and 75 cases without VETC. Observation indica-tors: (1) clinical characteristics of patients with and without VETC; (2) imaging features of patients with and without VETC; (3) multivariable analysis of HCC patients with VETC; (4) construction of VETC related risk scoring model and its performance evaluation; (5) postoperative early tumor recurrence of patients with and without VETC who were confirmed by risk scoring model and histopathological examination. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolutes, and comparison between groups was conducted using the chi-square test and continuous correction chi-square test. Variables of clinical and imaging characteristics with statistically signifi-cant were included in the multivariate analysis. Multivariate analysis was conducted using the Logistic regression model of backward stepwise selection. VETC related risk scoring model was constructed based on the results of Logistic regression model. The receiver operating characteristic (ROC) curve was drawn, and the area under curve (AUC), the sensitivity, specificity, accuracy and their 95% confidence interval ( CI) were calculated. The maximizing Youden index was the optimal cutoff value for VETC prediction. The Hosmer Lemeshow goodness of fit test was used to assess the consistency between VETC risk scoring model predicted VTEC status and the true VETC status. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-rank test was used for survival analysis. Results:(1) Clinical characteristics of patients with and without VETC. Cases with postoperative albumin <36 g/L were 57 in patients with VETC, versus 68 in patients without VETC, respectively, showing a significant difference between them ( χ2=5.13, P<0.05). (2) Imaging features of patients with and without VETC. Cases with lesion imaging presence as nonperipheral washout, cases with lesion imaging presence as mosaic architecture, cases with lesion imaging presence as intratumoral hemorrhage, cases with lesion imaging presence as corona enhancement, cases with lesion imaging presence as non-smooth tumor margin, cases with lesion imaging presence as peritumoral enhancement in arterial phase, cases with lesion imaging presence as intratumoral arteries, cases with lesion imaging presence as peritumoral hypointensity in hepatobiliary phase, cases with lesion imaging enhancement type as uniform low enhancement, uniform high enhance-ment, heterogeneous enhancement with septations and heterogeneous enhancement with irregular ring-like structures, cases with intratumoral necrosis or ischemic, cases with tumor diameter >5 cm were 73, 35, 33, 15, 39, 28, 42, 27, 4, 5, 27, 38, 45, 46 in patients with VETC, versus 64, 16, 13, 3, 19, 15, 9, 13, 9, 35, 5, 26, 10, 10 in patients without VETC, respectively, showing significant differences in the above indicators between them ( χ2=8.92, 11.15, 12.97, 9.28, 11.74, 5.77, 33.14, 6.96, 41.79, 36.05, 37.86, P<0.05). (3) Multivariable analysis of patients with VETC. Results of multivariable analysis showed that lesion imaging enhancement as heterogeneous enhancement with septations, lesion imaging enhancement as heterogeneous enhancement with irregular ring-like structures, intratumoral necrosis or ischemia and tumor diameter >5 cm were independent risk factors influen-cing patients with VETC ( odds ratio=4.18, 7.62, 4.23, 4.08, 95% CI as 1.60?11.60, 2.00?31.70, 1.71?10.90, 1.60?10.80), P<0.05). (4) Construction of VETC related risk scoring model and its performance evaluation. The VETC related risk scoring model was constructed as (heterogeneous enhancement with septations, presence: 1.0, absence: 0)+(heterogeneous enhancement with irregular ring-like structures, presence: 1.5, absence: 0)+(intratumoral necrosis or ischemia, presence: 1.0, absence: 0)+(main tumor diameter >5 cm, presence: 1.0, absence: 0). The AUC, sensitivity, specificity, and accuracy of VETC related risk scoring model were 0.86 (95% CI as 0.80?0.92), 79.7% (95% CI as 69.2%?87.3%), 80.0% (95% CI as 69.6%?87.5%) and 79.9% (95% CI as 72.7%?85.5%), respectively. Results of Hosmer-Lemeshow goodness of fit test showed a good consistency between VETC risk scoring model predicted VETC status and true VETC status ( P>0.05). (5) Postoperative early tumor recurrence of patients with and without VETC who were confirmed by risk scoring model and histopathological examination. All 149 patients were followed up for 29(range, 26?35)months. The time to tumor recurrence and 2-year cumulative tumor recurrence rate of 149 patients were 29(range, 24?33)months and 43.0%, respectively. The 2-year tumor cumulative recurrence rate of patients with and without VETC predicted by risk scoring model was 47.8% and 37.9%, respectively, showing a significant difference between ( χ2=3.90, P<0.05). The 2-year cumulative tumor recurrence rate of patients with and without VETC confirmed by postoperative histopathological examination was 47.4% and 38.1%, respectively, showing a significant difference between ( χ2=4.20, P<0.05). Conclusions:Lesion imaging enhancement as heterogeneous enhancement with septations or irregular ring-like structures, intratumoral necrosis or ischemia and tumor diameter >5 cm are independent risk factors influen-cing HCC patients with VETC. The proposed risk scoring model based on those three risk factors achieves an optimal preoperative diagnostic performance.

Objective To investigate the association of energy metabolic markers with the risk of spontaneous bacterial peritonitis (SBP) in patients with decompensated hepatitis B virus-related liver cirrhosis (HBV-LC). Methods A retrospective analysis was performed for the clinical data of the patients with decompensated HBV-LC who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from November 2017 to November 2019, and baseline clinical parameters and energy metabolic markers were compared between the patients with SBP and those without SBP within 2 weeks after admission. A multivariate logistic regression analysis was performed to investigate the risk factors for SBP. The t -test was used for comparison of normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between two groups; the Fisher's exact test was used for comparison of categorical data between two groups. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency of the newly established logistic regression model, and with the corresponding point of Youden index as the cut-off value, the DeLong test was used to compare the area under the ROC curve (AUC). Results A total of 50 patients with decompensated HBV-LC were included, among whom 23 (46%) developed SBP within 2 weeks after admission and 27 (54%) had no SBP during hospitalization. Compared with the non-SBP patients, the SBP patients had significantly lower triglyceride, prealbumin, and prothrombin time activity (PTA) and significantly higher international normalization ratio, C-reactive protein (CRP), and Model for End-Stage Liver Disease score (all P < 0.05). Comparison of baseline energy metabolic markers showed that compared with the non-SBP patients, the SBP patients had significantly lower respiratory quotient (RQ) [0.79(0.76-0.86) vs 0.85(0.79-0.91), P =0.041] and carbohydrate oxidation (CHO) rate [20.50%(15.25%-41.05%) vs 41.6%(22.25%-68.05%), P =0.041]. The multivariate logistic regression analysis showed that PTA was an independent risk factor for SBP in the patients with decompensated HBV-LC during hospitalization (odd ratio=0.004, P =0.008), and the regression model established based on the variables including PTA, CRP, RQ, and CHO had an AUC of 85.0% and a cut-off value of 0.60 at the maximum Youden index, with a specificity of 85.19% and a sensitivity of 73.91%, suggesting that this model had a better discriminatory ability than CRP (AUC=74.5%, P =0.049) and procalcitonin (AUC=56.4%, P < 0.01). Conclusion There are significant reductions in the energy metabolic markers RQ and CHO in the patients with decompensated HBV-LC who develop SBP within a short term, and their combination with PTA, CRP, and CHO/RQ ratio can help clinicians identify the patients at a high risk of SBP in the early stage and enhance nutrition support for such patients.
