ObjectiveTo systematically analyze the differences in therapeutic efficacy between intensity-modulated radiotherapy （IMRT） and stereotactic body radiotherapy （SBRT） for locally advanced pancreatic cancer （LAPC）， and to provide a basis for treatment decision-making. MethodsPubMed， Embase， the Cochrane Library， CNKI， Wanfang Data， and VIP databases were searched for prospective or retrospective cohort studies on IMRT versus SBRT for the treatment of LAPC published up to July 31， 2025. The Newcastle-Ottawa Scale was used to assess the quality of studies， and Review Manager 5.4 was used to perform the Meta-analysis. ResultsA total of 23 studies involving 2 505 patients were included. In terms of local control rate， an analysis of 13 studies with 847 patients showed that the SBRT group had a significantly higher 1-year local control rate than the IMRT group （84.5% vs 66.7%， relative risk ［RR］=1.27， 95% confidence interval ［CI］： 1.03 — 1.56， I²=28%， P=0.026）. In terms of acute toxicity， an analysis of 15 studies showed that the SBRT group had a significantly lower incidence rate of grade≥3 acute toxicity than the IMRT group （3.5% vs 11.0%， RR=0.32， 95%CI： 0.19 — 0.53， I²=18%， P<0.001）. There was no significant difference in overall survival between the SBRT group and the IMRT group （16.8 months vs 16.3 months）. The subgroup analysis of local control rate showed that in the 9 high-quality studies， the SBRT group had a significantly higher local control rate than the IMRT group （RR=1.25， P<0.001）， and a similar result was observed in the 4 moderate-quality studies （RR=1.31， P=0.021）； the stratified analysis based on technique platforms showed that the MR-guided technique group showed the largest effect size （RR=1.40， I²=10%）. The sensitivity analysis showed that the RR value ranged from 1.21 to 1.28， with stable results. The Egger regression analysis showed no significant publication bias （P>0.05）. ConclusionSBRT is superior to IMRT in terms of local control rate and acute toxicity and is a preferred treatment option for LAPC， with the MR-guided techniques showing the best performance.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

BACKGROUND: Most Chinese migrants have been faced with obstacles to getting access to local public health services. Young migrants among internal migrants make a major contribution to the economy. However, the establishment of their health records has been ignored. This research was aimed at exploring the status and associated factors of the establishment of health records among young Chinese migrants. METHODS: Data were obtained from the 2017 China Migrants Dynamic Survey (CMDS). Chi-square test and binary logistic regression were performed to investigate the associated factors of the establishment of health records among young Chinese migrants. RESULTS: Approximately 30.2% of young migrants had their health records established in inflow communities. Urban residence, medical insurance (insured), and lower average monthly household income were attributed to the establishment of more health records. Young migrants who were in northeast China and across provinces and immigrated for working or engaging in trade were less likely to have health records established. Young migrants who participated in social activities and public affairs activities and took type of people in touch as natives in the inflow area showed a higher possibility of establishing health records. Meanwhile, receiving health education and hearing about national basic public health services (BPHSs) were beneficial for establishing the health records of more young migrants. CONCLUSION This study showed that the health records of young migrants had a relatively low establishment rate. Sociodemographic and migration characteristics, health status, public health services, and social integration factors were all related to the health record establishment of young Chinese migrants.

BACKGROUND: Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality. METHODS: A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data. RESULTS: The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P < 0.001) and negative coping style (B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality (B = -0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles. CONCLUSIONS Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

Objective: This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress. Methods: Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis. Results: The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029). Conclusion The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365
