Objective: To analyze the current status of clinical trial registration for childhood and adolescent obesity, so as to provide insights for the registration and implementation of related trials. Methods: ClinicalTrials.gov and the ChiCTR database were searched for obesity related clinical trial registrations up to 1 June 2025. Data included basic characteristics (registration region, date, funding source, status, sample size), trial design features, participant demographics, interventions, outcome measures, methodology, and reporting quality. Statistical and descriptive analyses were conducted. Results: A total of 1 450 registered studies were included, covering 59 regions globally. North America hosted the highest number of registrations (876, 60.41%), with the United States accounting for the largest share (771, 53.17%). The earliest registered study dated to 1985, while 2016 saw the highest annual registrations ( n =87). Funding sources predominantly originated from universities (834 studies, 57.52%). Currently, completed trials accounted for the majority (1 003 trials, 69.17%). Globally, the majority of studies employed sample sizes within the 11-50 range (331 studies, 22.83%). Interventional studies predominated in design type (1 186, 81.79%), predominantly employing randomized parallel group controlled trials. Main interventions included comprehensive lifestyle interventions, physical activity and exercise interventions, and diet and nutrition interventions. High frequency outcome indicators primarily involved body composition and anthropometric measurements, metabolic and biochemical indicators, etc. Methodology and reporting quality required improvement. Conclusions The registration of clinical trials related to childhood and adolescent obesity globally shows a positive development trend, but issues of regional imbalance and methodological limitations exist. It is necessary to strengthen clinical trial registration norms, optimize study designs, and focus on the innovation of interventions and the systematicity of outcome indicators.

Objective To explore the clinical safety of plasma exchange(PE)combined with early continuous renal replacement therapy(CRRT)and its effects on coagulation and immune functions in patients with polytrauma and hypermyoglobinemia.Methods A non-randomized controlled study was conducted on 60 patients with severe polytrauma and myoglobinemia hospitalized in our department from January 2021 to December 2024.Based on different blood purification,the patients were divided a control group(CRRT)combined with conventional basic treatment,n=30)and an observation group(PE+CRRT and conventional basic treatment,n=30).Biochemical indicators(myoglobin,Mb),inflammation-related indicators,peripheral blood lymphocyte subsets,coagulation indicators,clinical-related indicators,and scores were observed and compared between the 2 groups before and after treatment.Results After 1,2 and 3 d of treatment,the levels of Mb,creatine kinase(CK),creatine kinase-MB isoenzyme(CK-MB),lactate dehydrogenase(LDH),serum creatinine(SCr),blood urea nitrogen(BUN),K+,C-reactive protein(CRP),procalcitonin(PCT),IL-6 and D-dimer(D-D),and white blood cell(WBC)count were significantly decreased in both groups(P<0.05).Among them,the observation group obtained obviously lower levels of all above indicators than the control group at the 3 time points(P<0.05).Additionally,notably shorter average length of total hospital stay,shorter average length of trauma intensive care unit stay,and lower score of acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)was observed in the observation group than the control group(P<0.05).There were no statistical differences in coagulation function indicators or T lymphocyte subsets between the 2 groups.No complications occurred.Conclusion For patients with polytrauma and hypermyoglobinemia,early application of PE+CRRT can effectively reduce serum myoglobin level,improve serum biochemical inicators,renal function and inflammatory status,and maintain homeostasis,but shows no effect on immune or coagulation functions.This approach is worthy of promoting in clinical practice.

Objective To investigate the mechanism by which cancer-associated fibroblast(CAF)in the tumor microenvironment regulate key pathways in prostate cancer stem cells(PCSCs).Methods An in vitro co-culture system of CAF and PCSC was established to observe the effects of CAF on PCSC proliferation and sphere formation.Prostate cancer stem cells were treated with CAF conditioned medium pre-treated with Wnt inhibitor DKK-1 and SDF-1 neutralizing anti-body(MAB310).Western blot was used to detect the expression of β-catenin,CXCR4,CD133 and CD44 in PCSCs.And PCR was used to detect the expression of β-catenin,CXCR4,TCF,and LEF mRNA.TOPflash/FOPflash dual-luciferase reporter assays were conducted to detect the effects of SDF-1 on Wnt/β-catenin signaling activity in PCSCs.Results ELISA results showed that the secretion of Wnt3a and SDF-1 in CAF supernatant was significantly higher than that in WPMY-1 cells(P＜0.05).The A value of PCSCs co-cultured with CAF at a 1∶6 ratio was significantly higher than that of the PCSC-only group(P＜0.0 1),and CAF promoted sphere formation in PCSCs(P＜0.05).Western blot results showed that CAF-CM significantly increased the relative expression of β-catenin,CXCR4,CD133 and CD44 in PCSCs(P＜0.01).Compared to CAF-CM,CAFanti-Wnt-CM significantly reduced the expression of β-catenin,CD133 and CD44(P＜0.01).CAFanti-SDF-1-CM also significantly inhibited the expression of CXCR4,β-catenin,CD133 and CD44(P＜0.01).PCR results showed that CAFanti-SDF-1-CM inhibited the expression of β-catenin,CXCR4 and downstream Wnt signaling effectors TCF and LEF(P＜0.01).Dual-luciferase reporter assay results showed that luciferase activity in the CAFanti-SDF-1-CM group was significantly lower than that in the CAF-CM group(P＜0.05).Conclusion CAF reg-ulates the stemness of PCSCs through the Wnt/β-catenin and SDF-1/CXCR4 pathways.CXCR4 may enhance the mainte-nance of stemness by activating β-catenin.

AIM:This study aims to investigate the protective effect of α-lipoic acid(α-LA)against alcohol-induced damage in H9c2 rat cardiomyocytes and to explore the underlying mechanisms.METHODS:An alcohol-induced injury model of H9c2 cells was established,and the cells were divided into 4 groups:control group,alcohol group,α-LA group,and alcohol+α-LA group.Additionally,H9c2 cells overexpressing aldehyde dehydrogenase 2(ALDH2)were cre-ated and further divided into 6 groups:normal control group,normal cells treated with alcohol group,normal cells treated with alcohol+α-LA group,ALDH2 overexpression group,ALDH2-overexpressing cardiomyocytes treated with alcohol group,and ALDH2-overexpressing cardiomyocytes treated with alcohol+α-LA group.Cell proliferation was assessed using 5-ethynyl-2'-deoxyuridine(EdU)staining.Reactive oxygen species(ROS)levels in each group were measured using di-hydroethidium(DHE)staining,while the expression levels of ALDH2,silent information regulator 1(SIRT1),heme oxy-genase 1(HO1)and P53 proteins were detected by Western blot analysis.RESULTS:(1)Alcohol exposure resulted in a decrease in the proliferation of H9c2 cells and an increase in intracellular oxidative stress,evidenced by elevated ROS levels and decreased expression of related proteins(ALDH2,SIRT1 and HO1).However,α-LA treatment significantly mitigated the decline in cell proliferation and the oxidative stress induced by alcohol.(2)Alcohol may induce cellular se-nescence,as demonstrated by the up-regulation of P53 expression,which were reversed by α-LA.(3)The H9c2 cells with high ALDH2 expression markedly improved the cell proliferation in the presence of alcohol,suppressed the ROS pro-duction,prevented the down-regulation of oxidative stress-related proteins(ALDH2,SIRT1 and HO1),and reversed the enhanced expression of the senescence marker P53.CONCLUSION:Treatment with α-LA may counteract oxidative stress and attenuate cellular senescence by activating ALDH2,thereby protecting cardiomyocytes from alcohol-induced damage.

Objective:To adapt the English version of exteroceptive body awareness questionnaire (EBA-q) into Chinese, and evaluate its reliability and validity in college students.Methods:English version EBA-q was translated and culturally adapted into Chinese, and the tests were administered from October to December 2024, with valid data collected from 1 071 college students. Item analysis, exploratory factor analysis, confirmatory factor analysis, criterion-related validity analysis, and reliability analysis were conducted by SPSS 23.0 and Mplus 8.3 softwares.Results:(1) The Chinese version of EBA-q contained seventeen items across five factors: visual awareness, tactile awareness, body coordination, awareness of body changes and awareness of clothing fit. The five-factor measurement model fitted the data well ( χ2/ df=2.24, CFI=0.95, TLI=0.94, RMSEA=0.05, SRMR=0.06). (2) The EBA-q scores were positively correlated with the scores of noticing, body listening, public self-consciousness, and private self-consciousness ( r=0.46, 0.36, 0.09, 0.25, all P<0.01). (3)The Cronbach's α coefficient, split-half reliability and test-retest reliability of the Chinese version of EBA-q were 0.79, 0.85 and 0.77, respectively(all P<0.01). Conclusion:The Chinese version of the EBA-q has demonstrated good reliability in assessing external body awareness among college students, but its validity requires further verification.

Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

Acupuncture-moxibustion therapy has been known to ameliorate the symptoms of functional gastrointestinal disorders (FGIDs), although its mechanism remains unclear. The paper reviews the articles on acupuncture-moxibustion therapy for FGIDs in recent 5 years, and it is revealed that acupuncture-moxibustion therapy can alleviate FGIDs symptoms through regulating gastrointestinal motility, modulating visceral hypersensitivity, improving the impaired gastric-duodenal mucosal barrier and inflammation, balancing intestinal microbiota, and adjusting the gut-brain axis. Currently, the molecular mechanism of acupuncture-moxibustion therapy remains unknown for FGIDs, the specific disease target is not identified, and the interaction among various molecules is not elucidated adequately. The researches in the future should employ advanced technologies and methodologies to comprehensively and deeply explore and clarify the mechanism of acupuncture- moxibustion therapy for FGIDs.
