Objective: To understand the impact of childhood trauma on psychological distress among upper grade elemetary school students, and to explore the mediating role of leisure activities in the relationship, so as to provide a basis for developing mental health intervention strategies. Methods: From August to November 2024, a combination of convenience sampling and stratified cluster random sampling was employed to recruit 1 373 fourth to sixth grade students from four primary schools in Harbin. The Childhood Trauma Questionnaire(CTQ), a self designed leisure activity scale (including active and passive leisure activities), and the Kessler Psychological Distress Scale (K10) were used to assess childhood trauma experiences, leisure activities, and levels of psychological distress. Spearman correlation analysis and linear regression analysis were conducted to explore the relationships among childhood trauma, leisure types, leisure time, and psychological distress. Based on the mediation analysis framework proposed by Hayes (Model 4), the mediating role of leisure types in the relationship between childhood trauma and psychological distress was examined. Results: Totally 19.1% of the upper elemetary school students exhibited psychological distress, while 30.2% had experienced childhood trauma. During school days, 64.6% of the students were reported of having leisure time concentrated between 1 and 5 hours per day, whereas 67.4% reported leisure time exceeding 5 hours per day on weekends. After controlling for potential demographic confounders such as gender, grade, ethnicity, household registration, being an only child, parents educational level, co residence, and whether parents are first time married,linear regression analysis showed that childhood trauma experience had positive predictive effect on psychological distress in upper primary school students( β =0.20, P <0.01). Leisure time showed no statistically significant association with psychological distress, both on school days ( β =-0.58 to -0.56) and weekends ( β =0.26- 0.98 )(all P >0.05). Active leisure activities were negatively associated with psychological distress ( β =-0.20), while passive leisure activities were positively associated with psychological distress ( β =0.29)(both P <0.01). Leisure type partially mediated the relationship between childhood trauma and psychological distress, accounting for 11.7% of the indirect effect. Conclusion Childhood trauma experiences positively predict psychological distress in upper elementary school students, and affect psychological distress through active leisure and passive leisure.

Objective: To explore the impact of sleep quality, experience of childhood maltreatment, and their interaction on depressive symptoms among middle school students, so as to provide the reference for early intervention of depressive symptoms among middle school students. Methods: From September to December 2023, a questionnaire survey was conducted among 1 231 students from two secondary schools in Harbin, Heilongjiang Province by a convenient sampling method. The survey included general demographic information, Childhood Trauma Questionnaire Short Form, Pittsburgh Sleep Quality Index and Short Version of Center for Epidemiological Studies Depression Scale. The Chi square test was used to analyze the differences in depressive symptom, sleep quality and childhood maltreatment among students with different demographic characteristics. Correlation analysis was conducted using Logistic regression, and interaction analysis was performed by both additive and multiplicative interaction models. Results: The detection rate of depressive symptoms among middle school students was 22.7%, and the rate for high school students (35.2%) was significantly higher than that for middle school students (17.0%) ( χ 2=50.35, P <0.01). The detection rates of depressive symptoms among middle school students with a history of childhood maltreatment and poor sleep quality were 45.8% and 44.0%, respectively. Multivariate Logistic regression analysis showed that compared to students without a history of childhood maltreatment, students with a history of childhood maltreatment had a higher risk of depressive symptoms ( OR =4.49，95% CI =3.31~ 6.09 , P <0.01);students with poor sleep quality had a higher risk of depressive symptoms than students with good sleep quality ( OR = 5.99，95% CI =4.37~8.22, P <0.01).The interaction results showed that the presence of childhood maltreatment and poor sleep quality had an additive interaction on the occurrence of depression in middle school students. Compared with students without childhood maltreatment and having good sleep quality, students with childhood maltreatment and poor sleep quality had a 22.49 times higher risk of developing depression ( OR =22.49，95% CI =14.22~35.59, P <0.01). Conclusion Depressive symptoms among middle school students are associated with childhood maltreatment and poor sleep quality, and there is an additive interaction between childhood maltreatment and poor sleep quality on the impact of depressive symptoms.

Objective To construct a key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury, and provide a basis for the implementation of such treatment and nursing. Methods The draft of the key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury was determined by literature review, case study, and field investigation. The indicators of the system were determined through two rounds of Delphi consultation and using the precedence chart method. According to the criteria of indicator evaluation, the reliability of expert opinions, and the opinions of the research group, the indicators were refined and evaluated.

The expert authority coefficients were both 0.945, and the Kendall’s W values were 0.347 and 0.448, respectively (P < 0.05). Following the expert consultations, 1 indicator was deleted, 12 indicators were added, and 6 indicators were modified. The key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury established in this study included 4 first-level indicators, 17 second-level indicators, and 73 third-level indicators. The means of importance assignment for all indicators were > 4.00, and the coefficients of variation were < 0.25. Conclusion The key technical indicator system for in-hospital treatment and nursing of patients with nuclear radiation injury established in this study is scientifically rigorous and practically grounded. The indicators demonstrate strong professional relevance and provide important guidance for in-hospital treatment and nursing of patients with nuclear radiation injury.

Hepatobiliary and pancreatic tumors are common types of digestive system disorders， and their complex pathogeneses have led to difficulties in early diagnosis and a high metastasis rate， with persistently high incidence and mortality rates in China， which greatly affects the quality of life and prognosis of patients. Studies have shown that heparanase （HPSE）， as a key effector molecule in matrix remodeling， plays a crucial regulatory role in tumor invasion and metastasis and microenvironment remodeling， and it is significantly associated with clinical prognosis. This article reviews the molecular mechanism of HPSE in hepatobiliary and pancreatic tumors， in order to provide a strong scientific basis for developing diagnostic markers and targeted interventions for hepatobiliary and pancreatic tumors.

Liver diseases are a group of complex clinical conditions caused by various factors and can lead to hepatocyte damage and liver dysfunction， posing a serious threat to human health.

ObjectiveTo investigate the mechanism of acupuncture in the treatment of chemotherapy-related cognitive impairment （CRCI） of breast cancer based on resting-state functional magnetic resonance imaging （rs-fMRI）. MethodTwenty-five patients with CRCI of breast cancer were included and treated with the acupuncture based on the method of regulating qi and blood， nourishing mind and benefiting intelligence； the selected acupoints included Zusanli （ST 36， bilateral）， Xuehai （SP 10， bilateral）， Tanzhong （CV 17）， Zhongwan （CV 12）， Qihai （CV 6）， Baihui （GV 20）， Fengfu （GV 16， bilateral）， Xinshu （BL 15， bilateral）， Tongli （HT 5， bilateral）， Zhaohai （KI 6， bilateral）， Yixi （BL 45， bilateral） twice a week， each time interval of 2-3 days， for 8 weeks. The scores of Montreal Cognitive Assessment （MoCA）， Mini-mental State Examination （MMSE）， European Cancer Research and Treatment Organization Quality of Life Questionnaire （EORTC QLQ-C30） were compared before and after acupuncture， and the effectiveness were evaluated by MoCA scale. The patients received rs-fMRI before and after treatment， and used low-frequency oscillation amplitude and functional connectivity （FC） analysis to extract the mean zALFF values of regions of interest such as bilateral anterior cingulate gyrus， bilateral hippocampus， bilateral amygdala， bilateral temporal pole middle temporal gyrus， and bilateral temporal pole supramarginal gyrus for comparison， and used the brain regions with statistically significant differences in the pre- and post-treatment zALFF values as the seed points for the seed-point-based FC Analysis. Correlation analyses were performed between the imaging metrics and the clinical scales. ResultsTwenty-four patients with CRCI of breast cancer completed treatment and follow-up. The zALFF values of the left hippocampus， left amygdala， and left temporal pole temporal gyrus in patients' rs-fMRI decreased after treatment （P＜0.05 or P＜0.01）， and left temporal pole temporal gyrus and right posterior cerebellar lobe FC were elevated （t = -5.169）， and MoCA scale total scores and visuospatial and executive， naming， and delayed recall cognitive scores， MMSE scale total scores， and EORTC QLQ-C30 scale mood scores were significantly higher （P＜0.05 or P＜0.01）. The total effective rate of MoCA was 58.33%. The difference in zALFF values of the left temporal pole middle temporal gyrus before and after treatment was negatively correlated with the MoCA total score （r= -0.499， P = 0.015）， as well as the difference in abstract function （r = -0.498， P = 0.016）. ConclusionThe acupuncture method of regulating qi and blood， nourishing mind and benefiting intelligence can improve the cognitive function of breast cancer patients with CRCI， and its mechanism may be related to improving the functional activities of hippocampus， amygdala and temporal lobe， as well as the functional connections of left temporal pole-temporal middle gyrus and right posterior cerebellar lobe.

OBJECTIVE To study the effects of transferrin-targeting peptide T7 （7pep） on intracellular transportation of polyethylene glycol-polycaprolactone （PEG-PCL） micelles in human cervical cancer HeLa cells. METHODS Using coumarin-6 （C6） as fluorescent indicator probe， both coumarin-6 （C6）-loaded PEG-PCL （PEG-PCL-C6） micelles and 7pep-modified PEG- PCL （7pep-PEG-PCL-C6） micelles were prepared by film-dispersion method. The particle size， polydispersity index and appearance morphology were compared between two types of micelles； the real-time uptake of two types of micelles by HeLa cells was compared， and the colocalization of two types of micelles with early endosomes （EE）， endocytic recycling compartments （ERC） and late endosomes （LE） after entry into the cells was observed. RESULTS The particle sizes of PEG-PCL-C6 and 7pep-PEG-PCL- C6 micelles were（75.0±2.3）and（82.0±1.5）nm； the polymer dispersity indexes were 0.17±0.20 and 0.17±0.32， respectively， with a regular spherical appearance. The colocalization results showed that entry speed and amount of 7pep-PEG-PCL-C6 micelles were significantly faster/more than those of PEG-PCL-C6 micelles. 7pep-PEG-PCL-C6 micelles entered EE faster than PEG-PCL-C6 micelles， while PEG-PCL-C6 micelles entered ERC at a faster rate than 7pep-PEG-PCL-C6 micelles， and both PEG-PCL-C6 micelles and 7pep-PEG-PCL-C6 micelles tended to accumulate gradually in LE； Pearson coefficient， signal overlap ratio， and colocalization ratio of 7pep-PEG-PCL-C6 micelles with LE were significantly lower 60 minutes after entering the cell than those 30 minutes after entering the cell （P＜0.05 or P＜0.01）. CONCLUSIONS Targeting 7pep modification can increase the entry speed and amount of PEG-PCL-C6 micelles， and also alter their intracellular transportation behavior.
