Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Background: The immune system plays a critical role in the development and progression of osteoporosis and fractures. However, the causal relationships between antibody immune responses, immune cells, and these bone conditions remain unclear. This study aimed to explore these relationships using Mendelian randomization (MR) analysis. Methods: We collected complete blood count data from patients with fractures and healthy individuals and analyzed their differences. Then, we conducted a 2-sample, 2-step MR analysis to investigate the causal effects of antibody immune responses on osteoporosis and fractures, using inverse-variance weighted (IVW) as the primary method. We also explored whether immune cells mediate the pathway between antibodies and osteoporosis or fractures. Finally, we analyzed the functions and expression levels of key genes involved. Results: Overall, the fracture group exhibited increased white blood cell count, absolute neutrophil count, absolute monocyte count, platelet count, and their respective proportions, while absolute lymphocyte count, absolute eosinophil count, absolute basophil count, red blood cell count, and their proportions were decreased. We identified 44 causal relationships between antibodies and osteoporosis or fractures, with 7 supported by multiple MR methods, and 5 showing odds ratios significantly deviating from 1 in the IVW analysis. Epstein-Barr virus-related antibodies had a notable impact on osteoporosis and fractures. The human leukocyte antigen (HLA) gene family, particularly HLA-DPB1, emerged as a significant risk factor. However, immune cells were not found to mediate these effects. Conclusions This study elucidated the causal relationships between antibody immune responses, immune cells, and osteoporosis or fractures. The HLA gene family plays a crucial role in the interaction between antibodies and these bone conditions, with HLA-DPB1 identified as a key risk gene. Immune cells do not serve as mediators in this process. These findings provide valuable insights for future research.

OBJECTIVE: To explore the incidence, clinical features, genetic variant characteristics and prognosis of Glutaric acidemia type I (GA1) among neonates from Henan Province. METHODS: A total of 814 625 neonates undergoing screening for inherited metabolic diseases by tandem mass spectrometry (MS/MS) at the Third Affiliated Hospital of Zhengzhou University from January 2016 to December 2022 were selected as the study subjects. A retrospective method was adopted to collect the clinical data of the patients. Whole exome sequencing was carried out to detect GCDH gene variants in individuals with positive results by GA1 newborn screening, and Sanger sequencing was used to verify the candidate variants. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the pathogenicity of candidate variants was rated. This study was approved by the Medical Ethics Committee of the Hospital (Ethics Number: 2019 Medical Ethics Review No. 67). RESULTS: Eight cases of GA1 were diagnosed among the 814 625 neonates. Blood glutaryl carnitine (C5DC) and urine glutaric acid (GA) levels of the 8 children were higher than the normal reference values. In total 12 variants were detected, all of which were missense variants. c.1064G>A (p.Arg355His) was the most common one, accounting for 21.4% (3/14). Three GCDH gene variants, including 1297G>C (p.Ala433Pro), c.467G>A (p.Gly156Asp) and c.1125T>G (p.Cys375Trp), were previously unreported. REVEL software analysis predicted that all of the three variants were harmful. 3D protein structure modeling indicated that the three variants may cause amino acid residue alterations, and c.1297G>C (p.Ala433Pro) and c.1125T>G (p.Cys375Trp) may result in increase in hydrogen bonds and affect the function of GCDH protein. By December 2023, one of the eight children had deceased, and another child had severe clinical symptoms with poor prognosis. Six children had a good prognosis, of which two had mild motor development delay and four had normal development without clinical symptoms. CONCLUSION The incidence of GA1 in newborns screened by MS/MS in Henan Province is 1/101 828, and the carrier rate of pathogenic GCDH variants is 1/160. The c.1064G>A (p.Arg355His) may be the hotspot variant of the GCDH gene among children with GA1 in Henan. Discovery of the three novel variants has enriched the mutational spectrum of the GCDH gene and provide a basis for the early diagnosis, treatment, prognosis and genetic counseling of this disease.

Objective To investigate the effects of Sini Powder on serum hypothalamic-pituitary-adrenal(HPA)axis-related hormones and inflammatory factors in liver cancer mice with comorbid depression,and to evaluate its effect on depressive behavior and tumor proliferation activity.Methods Forty-eight specific pathogen-free female C57BL/6 mice were randomly assigned to either a blank(n=8)or model group(n=40).The modeling group was subjected to chronic unpredictable mild stress(CUMS)for six weeks.Both groups underwent orthotopically transplanted liver tumor surgery at the end of the fourth week of CUMS treatment.At the end of the sixth week of CUMS treatment,color Doppler ultrasonography was used to observe tumor formation in the orthotopic transplantation liver tumors,and the tail suspension test was used to assess depressive behavior.Non-tumor-bearing and deceased mice were excluded.The remaining model group mice were stratified by tail suspension immobility time and randomly assigned to the following groups:model group(distilled water),Fluoxetine group(5.0 mg/kg),and Sini Powder low-dose,medium-dose,and high-dose groups(5.2,10.4,and 20.8 g/kg,respectively),with six mice per group.The treatments were administered once daily for 21 consecutive days.After treatment,depressive behaviors were assessed using the open field,tail suspension,and forced swimming tests.The proliferation status of the orthotopic liver transplantation tumor was evaluated by measuring the size of the tumor,observing pathological changes in the tumor tissue through hematoxylin and eosin staining,and detecting the positive cell rate of proliferating cell nuclear antigen(Ki-67)in the tumor tissue using immunohistochemistry.The levels of HPA axis-related hormones in serum,such as corticotropin-releasing hormone(CRH),adrenocorticotropic hormone(ACTH),corticosterone(CORT),as well as inflammatory factors such as tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and interleukin-6(IL-6)were measured using an enzyme-linked immunosorbent assay.Western blotting was used to assess mitogen-activated protein kinase(MAPKs)phosphorylation and the expression of nuclear factor-κB(NF-κB),NOD-like receptor family pyrin domain-containing receptor 3(NLRP3),and cysteine aspartic protease-1(Caspase-1)in orthotopic tumors.Results Compared with the blank group,the model group showed reduced total distance traveled in open field test,prolonged immobility times in the tail suspension and forced swimming tests(P<0.05,P<0.01),indicating successful establishment of the liver cancer with comorbid depression mice model.Also,the model group showed increased orthotopic tumor volume(P<0.01),and elevated serum CRH,ACTH,CORT,TNF-α,IL-1β,and IL-6 levels(P<0.01).The phosphorylation of MAPKs in tumor tissues was suppressed(P<0.01),while NF-κB,NLRP3,and Caspase-1 expression levels were downregulated(P<0.01).Compared with the model group,Sini Powder medium-and high-dose groups exhibited increased total distance traveled in the open field test(P<0.05),reduced forced swimming test and prolonged total distance traveled in open field test(P<0.01),while Sini Powder high-dose group showed reduced immobility times in the tail suspension test(P<0.05).Also,Sini Powder low-dose,medium-dose,and high-dose groups showed slower tumor growth,histological changes,including vacuolization and necrosis,decreased Ki-67 positive cell rate(P<0.01),and reduced serum CRH,ACTH,CORT,TNF-α,IL-1β,and IL-6 levels(P<0.05).Additionally,the phosphorylation of MAPKs in tumor tissues was suppressed(P<0.01),and NF-κB,NLRP3,and caspase-1 expression levels were downregulated(P<0.01).Conclusion Sini Powder may alleviate depressive behaviors and suppress tumor proliferation activity in liver cancer mice with comorbid depression by modulating MAPKs activation,inhibiting NF-κB,NLRP3,and Caspase-1 expressions,and reducing serum inflammatory factors and HPA axis-related hormones levels.

AIM:To investigate the effect of Jianpi-Huayu decoction(JPHYD)combined with gemcitabine(GEM)on ferroptosis of pancreatic cancer PANC-1 cells and its mechanism.METHODS:PANC-1 cells were cultured in vitro,and CCK8 method was used to detect the cell viability after different concentrations of JPHYD and GEM,and ap-propriate concentrations were selected for follow-up experiments.EDU assay and clonogenesis assay were used to detect cell proliferation.The apoptosis rate was detected by flow cytometry.Intracellular reactive oxygen species(ROS)were de-tected by DCFH-DA fluorescent probe and lipid peroxidation was detected by BODIPY 581/591C11 staining.The contents of glutathione(GSH),ferrous ion(Fe2+)and malondialdehyde(MDA)in the cells were detected by the kit.The mRNA levels and protein expression levels of Nrf2,HO-1,SLC7A11,GPX4,TFR1 and ACSL4 were detected by RT-qPCR and Western blot.RESULTS:Compared with the control group,the cell viability of PANC-1 treated with JPHYD and GEM was significantly decreased in a concentration-dependent manner.And the combined use of the two can significantly im-prove the cytotoxic effect of GEM and have a synergistic effect;Compared with control group,JPHYD group,GEM group and JPHYD+GEM group can significantly reduce EDU positive efficiency,colony formation numbers and promote cell apoptosis,and the combined group has the most obvious effect.After adding JPHYD+GEM into the cells,the cells be-came rounded and the cell viability decreased.The addition of ferrostatin-1(Fer-1),an inhibitor of ferroptosis,had no significant effect on cell morphology and viability,and the co-treatment with JPHYD+GEM and Fer-1 could reverse the ef-fects of JPHYD+GEM on cell morphology and viability.Compared with control group and GEM group,JPHYD+GEM group can significantly increase the levels of intracellular reactive oxygen species(ROS)and lipid peroxidation,increase the levels of Fe2+and MDA,decrease the levels of GSH,further promote lipid peroxidation and induce ferroptosis.JPHYD+GEM also significantly down-regulated the mRNA and protein expressions of Nrf2,HO-1,SLC7A11 and GPX4,and up-regulated the mRNA and protein expressions of TFR1 and ACSL4.The addition of Fer-1 significantly reversed the activation of iron death in the combined treatment group and reversed its efficacy,and the difference was statistically signif-icant.CONCLUSION:Jianpi Huayu decoction and gemcitabine may induce ferroptosis of PANC-1 cells by inhibiting Nrf2/SLC7A11/GPX4 axis in vitro,thus playing a synergistic anticancer role.

Objective:To validate the effectiveness of the leaf position data of multi-leaf collimator (MLC) recorded in the Infinity medical linear accelerator log file (LF).Methods:In this study, the establishment of the film dose calibration curve involved two steps. Initially, the pixel values obtained from scanning the film were converted into net optical density values. Subsequently, a sixth-order polynomial fit was performed on the net optical density and dose data. The picket fence (PF) tests were performed on the electronic portal imaging device (EPID) and film, and the corresponding acquired PF test images were analyzed using the relative leaf travel distance, relative leaf position, relative leaf pair full-width half -maximum (FWHM), and relative leaf pair neighbor region width analysis index, and compared with the relevant results in LF. In addition, to investigate the effect of gravity on the recorded leaf position data by the Infinity medical linear accelerator LF, the above PF tests were executed at 0°, 90°, 180°, and 270° gantry angles, respectively. Intergroup differences were assessed with the Wilcoxon rank-sum test.Results:The film dose calibration curve demonstrated high goodness-of-fit, with a correlation coefficient ( R2) of 0.9994. Across all gantry angles, the dispersion of overall leaf position data for EBT3 film, EPID, and LF followed a consistent pattern based on four analysis metrics: EBT3 film > EPID > LF. Moreover, for each analysis metric, inter-tool differences in standard deviations of results were consistently below 0.1 mm, and this pattern was invariant to gantry angle. Conclusions:The leaf position data recorded in the Infinity medical linear accelerator LF have a high degree of accuracy, and can be used as reference for the actual position of the MLC leaf. Furthermore, gravitational forces exhibit negligible impact on leaf position data acquired via LF.

Objectives:To explore the independent and combined effects of sleep duration and physical activity(PA)on the incidence of cardiovascular disease(CVD).Methods:The study subjects were derived from three sub-cohorts of the China-PAR project.Information on sleep and PA was collected from the surveys conducted in 2007-2008,and the incidence and mortality data of CVD were obtained during the follow-up survey from 2012 to 2015.Sleep duration was categorized into≤6 h/d,>6-8 h/d,and>8 h/d,and the PA level was classified according to the tertiles of PA volume(MET-h/d).The Cox proportional hazards model stratified by cohort source was applied to estimate the associations of PA and sleep duration with CVD incidence,coronary heart disease(CHD)incidence,and stroke incidence.Results:A total of 93 933 participants were included.During an average follow-up of(5.82±0.98)years,3 862 CVD events were documented.Compared with the low PA group,the hazard ratios(HRs)and 95%confidence intervals(CIs)of the CVD incidence,CHD incidence,and stroke incidence for the high PA group were 0.73(0.65-0.82),0.62(0.49-0.77)and 0.88(0.76-1.01),respectively.A U-shaped relation between sleep duration and incidence of CVD and stroke was observed.Compared with those who slept for>6-8 h/d,the risk of CVD(HR[95%CI]:1.10[1.00-1.21],P=0.04)and stroke(HR[95%CI]:1.33[1.18-1.49],P<0.01)was higher among participants slept>8 h/d.The risk of CVD,CHD and stroke tended to be higher in the≤6 h/d sleep group.Compared with the high PA combined with>6-8 h/d,the risk of stroke was highest in the high PA combined with>8h/d sleep group(HR[95%CI]:1.74[1.37-2.22],P<0.05),while the risks of CVD(HR[95%CI]:1.69[1.39-2.04],P<0.05)and CHD(HR[95%CI]:1.99[1.41-2.81],P<0.05)were highest in the low PA combined with≤6 h/d sleep group.Conclusions:Adequate physical activity and appropriate sleep duration are associated with lower risk of morbidity from CVD,CHD and stroke.
