Objective: To analyze the association of mother-child interaction and screen exposure of preschool children with psychological and behavioural problems, so as to provide guidance for promoting the psychological development of preschool children. Methods: From November to December 2024, a convenience cluster sampling method was used to survey 2 977 mothers of preschool children in Daguan and Yingjiang districts of Anqing City. The Chinese Parent-Child Interaction Scale (CPCIS) was applied to evaluate the quality of mother-child interaction, and the Conners Parent Symptom Questionnaire (PSQ) was used to assess the psychological and behavioral problems of preschool children. Binary Logistic regression was applied to analyze the association of mother-child interaction, screen exposure and their combined effect on psychological and behavioral problems among preschool children. Results: The detection rate of psychological and behavioral problems among preschool children was 13.9%. Binary Logistic regression results showed that low scores of mother-child interaction ( OR=2.31, 95%CI =1.72-3.11) and high screen exposure ( OR= 1.52 , 95%CI =1.23-1.88) were higher risks for psychological and behavioral problems in preschool children; the results of the combined effect showed that preschool children in low scores of mother-child interaction and low screen exposure group ( OR=2.18, 95%CI =1.46-3.28), low scores of mother-child interaction and high screen exposure group ( OR=3.13, 95%CI =2.10- 4.65 ) had significantly higher risks of abnormal detection in psychological and behavioral problems, compared to those in the high scores of mother-child interaction and low screen exposure group respectively (all P <0.05). Conclusions Both screen exposure and mother- child interaction are associated with psychological and behavioral problems in preschool children. High quality mother-child interaction can relieve the adverse effects of screen exposure on preschool children s psychological and behavioral development.

The density and composition of lymphocytes infiltrating colon tumors serve as predictive factors for the clinical outcome of colon cancer.Our previous studies highlighted the potent anti-cancer properties of the principal compounds found in Garcinia yunnanensis(YTE-17),attributing these effects to the regu-lation of multiple signaling pathways.However,knowledge regarding the mechanism and effect of YTE-17 in the prevention of colorectal cancer is limited.In this study,we conducted isobaric tags for relative and absolute quantification(iTRAQ)analysis on intestinal epithelial cells(IECs)exposed YTE-17,both in vitro and in vivo,revealing a significant inhibition of the Wnt family member 5a(Wnt5a)/c-Jun N-terminal kinase(JNK)signaling pathway.Subsequently,we elucidated the influence and mechanism of YTE-17 on the tumor microenvironment(TME),specifically focusing on macrophage-mediated T helper 17(Th17)cell induction in a colitis-associated cancer(CAC)model with Wnt5a deletion.Additionally,we performed the single-cell RNA sequencing(scRNA-seq)on the colonic tissue from the Wnt5a-deleted CAC model to characterize the composition,lineage,and functional status of immune mesenchymal cells during different stages of colorectal cancer(CRC)progression.Remarkably,our findings demon-strate a significant reduction in M2 macrophage polarization and Th17 cell phenotype upon treatment with YTE-17,leading to the restoration of regulatory T(Treg)/Th17 cell balance in azoxymethane(AOM)/dextran sodium sulfate(DSS)model.Furthermore,we also confirmed that YTE-17 effectively inhibited the glycolysis of Th17 cells in both direct and indirect co-culture systems with M2 macrophages.Notably,our study shed light on potential mechanisms linking the non-canonical Wnt5a/JNK signaling pathway and well-established canonical β-catenin oncogenic pathway in vivo.Specifically,we proposed that Wnt5a/JNK signaling activity in IECs promotes the development of cancer stem cells with β-catenin activity within the TME,involving macrophages and T cells.In summary,our study undergoes the po-tential of YTE-17 as a preventive strategy against CRC development by addressing the imbalance with the immune microenvironment,thereby mitigating the risk of malignancies.

Objective:To investigate whether octyl ester derivative of ginsenoside Rh2(Rh2-O)can induce immunogenic cell death of Huh-7 hepatocellular carcinoma cells and possible mechanism.Methods:Huh-7 cells were cultured in vitro,and divided into control group,Rh2-O group,positive control group(mitoxantrone treatment).Viability and apoptosis of cells were detected by CCK-8 and flow cytometry,respectively.Concentrations of high mobility family protein 1(HMGB1)and adenosine triphosphate(ATP)in supernatant were detected by ELISA and chemiluminescence assay,respectively.Membrane eversion of calreticulin(CRT)was detected by immunofluorescence assay.ROS level in cells was detected by fluorescence probe DCFH-DA,and expressions of proteins associated with endoplasmic reticulum stress signaling pathway were detected by Western blot.Results:Rh2-O treatment significantly reduced cell viability,promoted apoptosis,induced secretion of HMGB1,ATP,membrane eversion of CRT,increased accumulation of ROS in cells,and enhanced expressions of endoplasmic reticulum stress-related proteins PERK,eIF2α,p-eIF2α(all P<0.05).After addition of endoplasmic reticulum stress inhibitor 4-phenylbutyric acid(4-PBA),membrane eversion of CRT induced by Rh2-O was significantly inhibited(P<0.05).Conclusion:Rh2-O can induce immunogenic cell death in hepatocellular carcinoma cells,whose mechanism may be associated with activation of endoplasmic reticulum stress and promotion of CRT membrane eversion.

In 2022,breast cancer ranks the first in incidence among all malignant tumors worldwide,and it's high recurrence and fatality rate has posed serious threat to human life and health.Triple negative breast cancer(TNBC)is known for its poor prognosis among all types of breast cancer,and is often associated with elevated expression of epidermal growth factor receptor(EGFR).EGFR is widely expressed on the surface of various cells.The signaling pathway mediated by EGFR is mainly involved in cell growth,proliferation and differentiation.EGFR overexpression is often closely related to tumor invasion,metastasis and prognosis.Therefore,elucidating the roles of EGFR in TNBC and developing prevention and treatment strategies correspondingly are helpful to prevent and control the occurrence of breast cancer,and improve patients'quality of life.This review summarizes the research progress in the roles of EGFR,the treatment strategies and drug resistance in TNBC,in order to provide more refence for treating and improving the prognosis of breast cancer.

Objective To evaluate the optimal degree of neuromuscular blockade for inhibiting obturator nerve-muscle responses induced by transurethral resection of bladder tumor (TURBT) with general anesthesia.Methods Ninety American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes,aged 26-64 yr,weighing 50-80 kg,scheduled for elective TURBT for lateral bladder wall tumors with general anesthesia,were divided into 3 groups (n =30 each) using a random number table:low-dose mivacurium group (group L),medium-dose mivacurium group (group M) and high-dose mivacurium group (group H).After mivacurium 0.15 mg/kg was injected intravenously during anesthesia induction,mivacurium was continuously infused at a rate of 0.2,0.3 and 0.4 mg · kg-1 · h-1 in L,M and H groups,respectively,until the end of operation.Neuromuscular blockade was continuously monitored during operation.When T1％ and TOF count (TOFC) disappeared,post tetanic count (PTC) was used.ROC curve was applied to analyze the relationship between the occurrence of obturator nerve-muscle responses and degree of neuromuscular blockade.Results T1％ and TOFC were recorded in 16 patients (15 cases in group L,1 case in group M) during the resection of tumor,and the obturator nerve-muscle response was observed in all of these patients.In the other 74 patients,T1％ and TOFC disappeared,and PTC recorded was 10.0±3.1 (group L,n=15),6.0± 3.5 (group M,n=29) and 4.0±2.2 (group H,n=30).Among the 74 patients,the obturator nerve-muscle response was found in 18 patients (8 cases in group L,10 cases in group M).The area under the ROC curve of PTC value in predicting the occurrence of obturator nerve-muscle responses was 0.882 with a PTC cut-off of 9 (P＜0.05).The sensitivity and specificity were 87.3％ and 72.2％,respectively.Conclusion In order to inhibit the obturator nerve-muscle response during TURBT with general anesthesia,the optimal degree of neuromuscular blockade should be kept not more than 9 for PTC.

Gastric cancer is one of the most common malignancies worldwide; however, the molecular mechanism in tumorigenesis still needs exploration. BCL2L11 belongs to the BCL-2 family, and acts as a central regulator of the intrinsic apoptotic cascade and mediates cell apoptosis. Although miRNAs have been reported to be involved in each stage of cancer development, the role of miR-24 in GC has not been reported yet. In the present study, miR-24 was found to be up-regulated while the expression of BCL2L11 was inhibited in tumor tissues of GC. Studies from both in vitro and in vivo shown that miR-24 regulates BCL2L11 expression by directly binding with 3'UTR of mRNA, thus promoting cell growth, migration while inhibiting cell apoptosis. Therefore, miR-24 is a novel onco-miRNA that can be potential drug targets for future clinical use.
