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 investigate the effect of lumbar sympathetic ganglion block (LSGB) on postoperative ileus (POI) in patients undergoing colonic surgery.Methods:Ninety patients scheduled for elective laparoscopic colonic surgery in the same treatment group at the Nanjing First Hospital from March 2022 to August 2023 were selected and randomly divided into a control group and an observation group using a random number table, with 45 patients in each group. The observation group received ultrasound-guided LSGB before anesthesia, while the control group received no intervention. Both groups received standardized anesthesia protocols and management after entering the operating room. The time to gastrointestinal motility recovery (first defecation time), first flatus time, first feeding time, number of cases requiring gastric tube decompression, postoperative hospital stay, number of cases with nausea and vomiting, intraoperative additional and titrated sufentanil dosage, remifentanil dosage, first patient-controlled intravenous analgesia (PCIA) press time, sufentanil dosage at 4, 8, 12, 16, and 24 hours postoperatively, and the number of analgesic pump presses were recorded.Results:Compared with the control group, the observation group had shorter first defecation and flatus times, earlier first feeding time, shorter postoperative hospital stay, and fewer cases of nausea (all P<0.05). The observation group also had less intraoperative sufentanil supplementation and titration, later first PCIA press time (all P<0.05), and significantly fewer sufentanil dosages and analgesic pump presses at 4, 8, 12, 16, and 24 hours postoperatively compared with the control group (all P<0.05). Conclusions:LSGB reduces the incidence of POI in colonic surgery patients, decreases opioid use, and shortens hospital stay.

Objective To explore the relationship between triglyceride-glucose(TyG)index and hypertension in patients with cerebral hemorrhage.Methods A total of 1718 patients with cere-bral hemorrhage admitted to our hospital from January,2013 to May,2023 were enrolled in this study.According to the TyG index quartile,437 cases were assigned into Q1 group(≤8.375),424 cases into Q2 group(TyG index 8.376～8.737),429 cases into Q3 group(TyG index 8.738～9.087),and 428 cases into Q4 group(≥9.088).The general clinical data were compared in the four groups.Logistic regression analysis was used to study the correlation between TyG index and hy-pertension.Results There were significant differences among the four groups in terms of age,hy-pertension,diabetes,SBP,DBP,TC,TG,HDL-C,LDL-C,FBG,glycated hemoglobin and TyG in-dex(P＜0.05,P＜0.01).Logistic regression analysis showed that when the TyG index was a con-tinuous variable,it was significantly correlated with the risk of hypertension(OR=1.999,95％CI:1.393-2.869,P=0.001).When the index was used as a categorical variable,with Q1as a ref-erence,TyG index in Q3 and Q4 was associated with an increase in OR of hypertension(OR=1.869,95％CI:1.220-2.865,P=0.004;OR=1.844,95％CI:1.125-3.020,P=0.015).After ad-justing cofounders,the association of TyG index and risk of hypertension was stronger in the fe-males(OR=2.618,95％CI:1.312-5.221,P=0.006)than the males(OR=1.783,95％CI:1.151-2.761,P=0.010),and in the patients ≥65 years old(OR=3.277,95％CI:1.600-6.741,P=0.001)than those＜65 years old(OR=1.782,95％CI:1.076-2.949,P=0.025).Conclusion TyG index is closely associated with hypertension in patients with cerebral hemorrhage,especially in women and elderly.

Acute ischemic stroke(AIS)is a common neurological disorder that still presents many challenges despite advancements in diagnostic and therapeutic techniques.Tissue kallikrein(TK),a cardiovascular and cerebrovascular protective factor,is involved in the entire process of AIS and holds significant clinical value.This review explores the mechanisms of TK in AIS,including targeting collateral circulation improvement in ischemic areas,protecting neurovascular coupling,reducing neuronal injury,and participating in remote ischemic conditioning.Additionally,plasma TK levels are negatively correlated with AIS incidence and recurrence risk,which can serve as a potential biomarker.TK therapy has been shown to improve neurological function in AIS patients,reduce recurrence rates and enhance outcomes when combined with reperfusion therapies.TK also demonstrates therapeutic benefits in AIS patients with multiple organ comorbidities.This review concludes the important roles of TK in the diagnosis,treatment,and prevention of AIS,providing new insights for future research and clinical applications.

Objective This study aims to explore the efficacy and complication rates of the transcranial approach(TCA)and extended endoscopic endonasal approach(EEEA)for the treatment of craniopharyngiomas based on the QST classification,providing a scientific reference for clinical decision-making on surgical approach.Methods A total of 151 patients who underwent craniopharyngioma surgery at our center from January 2018 to December 2023 were enrolled.The patients were categorized into Q-CP(suprasellar type),S-CP(infundibular type),and T-CP(tuberal type)according to the QST classification.Systematic collection and analysis were performed on the outcomes of TCA and EEEA treatments,respectively.The differences in effectiveness between the two approaches were evaluated based on the QST classification.Results The improvement rate of visual symptoms was overall higher in the EEEA group than in the TCA group(59.1%vs.36.5%,P=0.006),and the visual deterioration rate was lower(3.0%vs.14.1%,P=0.006).However,the incidence of cerebrospinal fluid leakage was higher in the EEEA group(15.2%vs.3.5%,χ2=4.986,P=0.026).The incidence of postoperative seizures(8.2%vs.0,P=0.019),brain contusions(10.6%vs.0,P=0.005),and subdural hematoma(9.4%vs.0%,P=0.01)was higher in the TCA group.For patients with Q-CP type,the EEEA group had a higher rate of total tumor resection(92.9%vs.65.2%,P=0.025)and a lower recurrence rate(3.6%vs.21.7%,P=0.047),with shorter hospital stays and lower postoperative costs.The TCA group had higher intraoperative blood loss in this type(300 mL vs.200 mL,Z=-2.261,P=0.024).For S-CP type patients,the EEEA group showed a higher rate of total tumor resection(91.3%vs.74.2%)and a lower recurrence rate(0 vs.12.9%,P=0.031),with lower postoperative hospital costs.In T-CP type,due to the deeper location,EEEA showed limitations in protecting hypothalamic function and the TCA group had a better postoperative hypothalamic function score(P=0.035).Conclusion Based on QST classification,EEEA has advantages in Q-CP and S-CP types and is recommended as the preferred surgical procedure;In the T-CP type,TCA surgery is more helpful in protecting hypothalamic function.

Objective To examine the association between lymphocyte subsets and renal clinicopathological characteristics as well as prognosis in patients with IgA nephropathy(IgAN).Methods The retrospective analysis included general clinical data and pathological examination results of IgAN patients diagnosed by renal biopsy at the Fourth Hospital of Hebei Medical University from January 2018 to January 2022.Correlation tests were conducted to examine the relationship between lymphocyte subsets and other significant clinicopathological parameters.The optimal cut-off value of CD4+T determined using the Youden index,and patients were grouped accordingly.Kaplan-Meier survival curves and Cox regression analyses were employed to compare the low and high CD4+T lymphocyte groups among IgAN patients,identifying factors influencing renal function progression.The endpoint event was defined as a decrease in estimated glomerular filtration rate(eGFR)of≥30%from baseline,progression to end-stage renal disease(ESRD)[eGFR<15 mL/(min·1.73 m2)or initiation of renal replacement therapy],or all-cause mortality.Results Low CD4+T lymphocytes were significantly positively correlated with blood IgA levels and the proportion of glomerular crescents in IgAN patients(all P<0.05).This study included a total of 53 IgAN patients,divided into two groups based on CD4+T lymphocyte counts:20 patients in the low CD4+T lymphocyte group and 33 patients in the high CD4+T lymphocyte group.In the low CD4+T lymphocyte group,there was a higher proportion of males and a lower proportion of glomerular crescents(P<0.05).Kaplan-Meier survival analysis revealed that patients with low CD4+lymphocytes had a significantly lower cumulative renal survival rate(Log-Rank test χ2=4.188,P=0.041).Cox regression analysis indicated that low CD4+lymphocytes were an independent risk factor for the progression of renal function decline in IgAN patients(HR=2.614,95%CI:1.006～6.788,P=0.048).Conclusions Patients with higher levels of CD4+T lymphocytes exhibit a lower risk of adverse renal outcomes.In contrast,patients with IgA nephropathy and low CD4+T lymphocyte counts tend to have poorer renal survival rates.

With the deepening of the reform of the medical and health system,the high-quality development of public hospitals has put forward higher requirements for the modern management system.This article takes a top-tier hospital in Huai'an as an example to explore the practical path and effectiveness of constructing a target management system for department directors in large public hospitals.The research achieved a comprehensive improvement in management efficiency by building a multi-di-mensional discipline evaluation system,promoting the construction of key specialties,creating a'trinity'medical quality man-agement system,strengthening the construction of quality control centers,and combining personalized target management respon-sibility agreements with the selection mechanism for outstanding department directors.Over the three years of implementation,key indicators of the hospital,such as the number of key specialties,CMI value,proportion of fourth-level surgeries,and average length of stay,have significantly improved.The research shows that this system,through the synergistic effect of goal orientation and performance incentives,effectively promotes the coordinated development of discipline construction,medical quality,and op-erational efficiency,providing a reference management paradigm for public hospitals to transition from scale expansion to connota-tion enhancement.
