Objective: To identify research priorities on physical and mental comorbidity among children and adolescents in Zhejiang Province, so as to provide a theoretical base for improving their physical and mental health. Methods: In May 2025, 77 experts in the fields of health and education from 11 cities in Zhejiang Province were selected by convenient sampling method to participate in the first round of expert consultation. In June, 2025, snowball sampling was used to expand to 194 experts for the second round of consultation, and it was convenient to select 21 students from primary schools to high schools in Zhejiang Province and 29 parents to empower the evaluation criteria. It applied the Child Health and Nutrition Research Initiative (CHNRI) method in a structured process, which encompassed the definition of the research field, generation of research ideas, scoring, and quantitative ranking of priorities. Research ideas were evaluated against 6 predefined criteria: effectiveness, safety, answerability, feasibility, sustainability, and scientific significance. Results: After 2 rounds of structured consultations, 81 research ideas on physical and mental comorbidity among children and adolescents were established and classified into 7 subthemes: epidemiological characteristics and influencing factors, optimization of primary service systems and policies, comprehensive intervention strategies for physical and mental comorbidity, biological mechanisms and clinical research, the impact of education and environment on physical and mental health, special populations and social support, and digital and technology driven disease prevention and intervention. The top 10 research priorities primarily centered on the subdomain of "epidemiological characteristics and influencing factors" (5 items). The top 3 research priorities were "the association between outdoor activity duration and the incidence of common diseases (including mental disorders) among children and adolescents" "the impact of outdoor activity duration on the physical and mental health of adolescents" "comprehensive intervention strategies for myopia, obesity, and their comorbidities among children and adolescents". Conclusion The framework of priority issues in the field of psychosomatic comorbidity of children and adolescents in Zhejiang Province based on CHNRI method provides a reference for optimizing the allocation of provincial research resources.

To investigate the effect of mesenchymal stromal cells (MSCs) on the fibrosis progression and endometrial regeneration in mouse models of endometrial injury, a mouse endometrial injury model was established by physical scraping combined with lipopolysaccharide (LPS) chemical induction, and the endometrium morphology and collagen deposition were evaluated by HE and Masson staining after unilateral administration of MSCs. RT-qPCR and immunofluorescence were used to detect the expression of epithelial markers Epcam and collagen I (Col1). Primary endometrial epithelial cells were isolated to assess p21 expression. Fibrosis-related genes and signaling pathways were validated using transcriptome sequencing and RT-qPCR. The experimental results showed that MSCs increased endometrial thickness and number of glands (P<0.05), up-regulated the expression of Epcam (P<0.01), while significantly reducing uterine collagen fiber deposition (P<0.05) and the expression of p21 in primary epithelial cells (P<0.0001). Transcriptomic analysis revealed that MSCs attenuated collagen deposition by modulating genes involved in the TGF-β signaling pathway. This study elucidates that MSCs facilitate uterine repair by reversing endometrial fibrosis and promoting epithelial regeneration, and their role is related to the regulation of the TGF-β/SMAD pathway and suppression of aberrant collagen accumulation.

Objective: To summarize strategies for improving childhood hypertension, so as to provide evidencebased recommendations for poliymaking and practice childhood hypertension management in China. Methods: From March to April 2024, child health stakeholders from five districts in Hangzhou were selected using a combination of stratified and convenience sampling methods. Data were analyzed using a groundedtheory approach. During the indepth interview phase, six policymakers were interviewed. Focus group discussions were conducted with school administrators, healthcare providers, and parents, comprising a total of 62 participants. Results: Through threelevel coding, 116 initial categories were identified(e.g., "trend of younger age" "difficulty in behavior change"), 35 main categories (e.g., "higher incidence compared to the past" "caused by comprehensive influencing factors"), and 12 core categories (e.g., "epidemic status" "influencing factors"). Finally, the cognitive status, problem analysis, and management strategies of children hypertension were constructed. Conclusion Effective prevention and control of childhood hypertension requires coordinated efforts among governments, schools, families, and society to establish a comprehensive management system, with dynamic monitoring and evaluation to optimize policy implementation.

Abstract Childhood hypertension is becoming a substantial public health challenge with profound implications for children s quality of life and long term health. The study analyzes the global prevalence of childhood hypertension and the relationship between macroecological factors, meso environmental factors, and micro individual factors based on the perspective of life course and childhood hypertension. And it further summarizes existing prevention and control strategies: systematic prevention and control based on policy and social support, health promotion based on behavioral science theory, and dynamic monitoring and management based on individualized prevention and control, to provide a reference for promoting the advancement of childhood hypertension prevention and control strategies.

Objective This study applies Roy adaptation theory to deeply explore the experience of food avoid-ance behavior in patients with inflammatory bowel disease(IBD),offering insights for developing dietary management strategies.Methods A descriptive qualitative research method was employed.By purposive sampling,24 IBD pa-tients hospitalized in the gastroenterology department of a tertiary hospital in Nanjing from July 2022 to December 2024 were selected for semi-structured interviews.Data were analyzed using a directed content analysis approach.Results This study identified 4 main themes and 11 sub-themes,encompassing overattribution leading to inappro-priate avoidance(recurrent symptoms triggering overattribution,disease staging triggering inappropriate avoidance),negative self-perception leading management struggles(illness fear diminishing self-efficacy,disease trauma eroding self-identity,knowledge deficiency constraining self-determination),functional impairment intensifying role challenges(role internalization undermining social function,social roles relinquishing dietary management),and external con-straints amplifying practical difficulties(family and friend oversight heightening dietary stress,healthcare gaps foster-ing practical helplessness,traditional beliefs restricting dietary exploration,economic hardship limiting balanced nu-trition).Conclusion The interplay of overattribution,negative self-perception,functional impairment,and external constraints in IBD patients hinders their ability to adapt to disease fluctuations,ensnaring them in the adaptive predicament of food avoidance behavior.Healthcare professionals should comprehensively address these factors by fostering accurate perceptions,enhancing psychological support,guiding effective coping strategies,and optimizing ex-ternal resources,thereby improving patients' overall adaptive capacity and promoting their recovery.

Objective To observe changes in voltage-dependent anion channel 3(VDAC3)in a mouse model of sepsis-induced myocardial injury and to explore its potential mechanism.Methods Twenty male C57BL/6J mice were divided randomly into a Sham group and Sepsis group,respectively(n=10 mice per group).Sepsis was induced by the cecal ligation and puncture(CLP).Serum levels of interleukin(IL)-6,tumor necrosis factor(TNF)-α,creatine kinase MB(CK-MB),and cardiac troponin T(cTnT)were detected by enzyme-linked immunosorbent assay.Pathological changes in heart tissue were observed by hematoxylin and eosin staining.Structural and functional changes in the heart were evaluated by echocardiography.Changes in total glutathione,reduced glutathione(GSH),oxidized glutathione,and malondialdehyde(MDA)in heart tissue were detected by spectrophotometry.The morphological structure of mitochondria in mouse cardiomyocytes was observed by transmission electron microscopy.Expression levels of IL-6,IL-1β,VDAC3,glutathione peroxidase 4(GPX4),solute carrier family 7 member 11(SLC7A11),lipocalin-2(LCN2),and prostaglandin-endoperoxide synthase 2(PTGS2)mRNA were detected by real-time quantitative polymerase chain reaction and the localization and expression of VDAC3 and GPX4 proteins in mouse heart tissue were detected by immunofluorescence staining.The correlations between VDAC3 mRNA and GPX4,SLC7A11,PTGS2,LCN2,IL-6,and IL-1β mRNA were analyzed.Expression levels of VDAC3,GPX4,and SLC7A11 proteins were detected by Western blot.Results IL-6,TNF-α,CK-MB,and cTnT levels were significantly higher in the Sepsis group compared with the Sham group(P＜0.05).In the Sepsis group,myocardial fibers were torn,the ventricular wall was thickened and edematous,the mitochondrial membrane was ruptured,and mitochondrial cristae were broken or absent.GSH levels were significantly reduced in the Sepsis group(P＜0.05)and the lipid peroxide MDA was increased in the Sepsis group(P＜0.05)compared with the Sham group.VDAC3,GPX4 and SLC7A11 mRNA and protein levels were all lower in the Sepsis group compared with the Sham group(P＜0.05),while expression levels of IL-6,IL-1β,LCN2,and PTGS2 mRNA were increased(P＜0.05).VDAC3 mRNA was positively correlated with GPX4 and SLC7A11 mRNA levels,and negatively correlated with LCN2,PTGS2,IL-6,and IL-1β.Conclusions VDAC3 expression decreases in myocardial injury,and it may participate in the occurrence of sepsis-induced myocardial injury by regulating ferroptosis.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

OBJECTIVE To explore the efficacy of low temperature plasma(LTP)in treatment of the rats with Pseudomonas aeruginosa(PA)wound infection.METHODS Totally 20 SD rats were assigned to establish the PA wound infection models and were randomly divided into the LTP group with 10 rats and the air control group with 10 rats.The wound healing dynamics,bacterial loading capacity,histopathology,levels of cytokines and microen-vironment features were observed during the healing process.RESULTS LTP accelerates the healing of PA infec-tion wound,the wound area reduced after the treatment for 3 days,and the inflammatory reactions alleviated;the infection symptoms subsided after the treatment for 7 days,and the wounds became dry and scabbed;the wounds reduced in size by day 15,showing favorable healing trends.Repeated measurement analysis of variance(ANOVA)indicated that there was significant difference in the impact of LTP on the covering rate of wounds(Ftime=10.230,P＜0.001;Fbetween-group=11.340,P=0.001;Finteraction=2.890,P=0.042).The result of quantitative bacterial loads analysis showed that the bacterial loads of the LTP group were lower than those of the control group after the treatment for 3,7 and 15 days(P＜0.05).The result of histopathology indicated that the infiltra-ted wound inflammatory cells of the LTP group reduced,the collagen fibers were well-aligned,and the neovascu-larization and formation of granulation tissues were evident.In addition,the pH value of wound tissues and reac-tive oxygen species(ROS)level were improved after the treatment with LTP,which was matched with the process of wound healing.The result of cytokines test showed that LTP could upregulate the levels of VEGF and TGF-β1,downregulate the levels of IL-1β and TNF-α,and promote the wound healing,with statistically signifi-cant differences observed(P＜0.05).CONCLUSION LTP may facilitate the control of infections by reducing the bacterial colony counts,establish the effective microenvironment for tissue healing,and accelerate the healing of wounds with PA infection by regulating the release of healing-related cytokines.

Objective:To develop a scientific and practical questionnaire for general practice residents, and to conduct multidimensional and comprehensive evaluation of the quality of general practice teaching clinics.Methods:A preliminary draft of the questionnaire items was formulated based on a literature review and in-depth interviews. The Delphi method was employed to conduct two rounds of consultation with 14 experts. Following revisions, a convenience sampling method was used to invite general practice residents from three standardized residency training bases to test the reliability and validity of the questionnaire.Results:The questionnaire consisted of 23 items, covering the three dimensions of preparation, implementation process, and comprehensive evaluation of the teaching clinics. The response rates for the two rounds of the expert consultation were both 100.00%, with expert authority coefficients of 0.89 and 0.90, respectively. The overall Cronbach's α coefficient of the questionnaire was 0.93, and the correlation coefficients between each item score and the total score were all >0.30. Structural validity analysis revealed that three common factors were extracted from the questionnaire, with a cumulative variance contribution rate of 77.89%. Conclusions:The General Practice Teaching Clinic Quality Evaluation Questionnaire for Residents developed in this study demonstrates high reliability and validity. The questionnaire provides a scientific basis for the standardized assessment of teaching quality in general practice clinics. By incorporating resident feedback on the teaching process, the questionnaire promotes the development of a teaching clinic quality improvement mechanism focused on residents and plays a significant role in enhancing the teaching capabilities of supervising physicians in clinics.
