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.

ObjectiveTo observe the long-term survival outcomes and complications of liver cirrhosis patients with spontaneous portosystemic shunt and type 1 isolated gastric varices （IGV-1） bleeding after secondary endoscopic preventive therapy， and to investigate the independent influencing factors for long-term prognosis. MethodsA total of 70 liver cirrhosis patients with spontaneous portosystemic shunt and IGV-1 bleeding who were admitted to Beijing Ditan Hospital， Capital Medical University， from January 5， 2015 to November 29， 2019 were enrolled as subjects， and related baseline data were collected， including age， sex， etiology， routine blood test results， liver function parameters， renal function parameters， coagulation parameters， Child-Pugh score， and the presence or absence of comorbidities such as cholestasis， hepatocellular carcinoma， thrombosis， ascites， and hepatic encephalopathy. All patients underwent secondary endoscopic preventive therapy for rebleeding and were followed up for 5 years. The primary endpoints were ectopic embolism rate and all-cause mortality rate， and the secondary endpoints were liver-related mortality and liver-related complications. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between groups， and the chi-square test was used for comparison of categorical data between groups. The Cox regression analysis was used to investigate the prognostic factors for 1-， 3-， and 5-year survival time， and the Logistic regression analysis was used to identify the independent risk factors for liver disease-related complications. ResultsThe incidence rate of ectopic embolism was 0% within 5 years of follow-up. The 1-， 3-， and 5-year all-cause mortality rates were 5.7%， 24.3%， and 32.9%， respectively. There were 2 cases of liver-related death in year 1， 8 cases in year 3， and 12 cases in year 5， resulting in a liver disease-related mortality rate of 17.14% （12/70）. Compared with the survival group， the death group had significantly higher incidence rates of hepatocellular carcinoma （0.00% vs 17.39%， χ²=8.669， P=0.003） and ascites （38.30% vs 52.17%， χ²=7.272， P=0.026）， and compared with the death group， the survival group had significantly lower 5-year incidence rates of rebleeding （10.64% vs 100.00%， χ²=51.383， P<0.001）， ascites （8.51% vs 52.17%， χ²=21.574， P<0.001）， and hepatic encephalopathy （0.00% vs 21.74%， χ²=12.029， P=0.002）. The multivariate Cox regression analysis showed that during the 1-year follow-up， comorbidity with hepatocellular carcinoma before surgery （hazard ratio ［HR］=14.601， 95% confidence interval ［CI］： 2.049 — 104.098， P=0.007） and PT （HR=1.662， 95%CI： 1.090 — 2.535， P=0.018） were independent risk factors for survival， and HGB level （HR=0.863， 95%CI： 0.747 — 0.998， P=0.046） was a protective factor for prolonged survival； during the long-term follow-up for 3 or 5 years， preoperative comorbidities with hepatocellular carcinoma （3 years： HR=40.174， 95%CI： 8.939 — 180.559， P<0.001； 5 years： HR=26.739， 95%CI： 6.993 — 102.243， P<0.001） and ascites （3 years： HR=3.638， 95%CI： 1.751 — 7.575， P=0.001； 5 years： HR=2.555， 95%CI： 1.419 — 4.598， P=0.002） were independent risk factors for mortality. The Logistic regression analysis showed that during the follow-up for 3 years， comorbidity with ascites before surgery （odds ratio ［OR］=0.255， 95%CI： 0.102 — 0.636， P=0.003） was associated with a lower risk of rebleeding， while comorbidity with hepatocellular carcinoma before surgery （OR=16.231， 95%CI： 1.298 — 202.878， P=0.031） was an independent risk factor for rebleeding； prothrombin time was a protective factor against hepatic encephalopathy （OR=0.790， 95%CI： 0.648 — 0.964， P=0.020）； during the follow-up for 5 years， aggravation of ascites after surgery （OR=5.578， 95%CI： 1.474 — 21.103， P=0.011） was an independent risk factor for rebleeding， and aggravation of ascites after surgery （OR=175.046， 95%CI： 14.306 — 2 141.909， P<0.001） were independent risk factors for the development of ascites in the future. ConclusionComorbidity with hepatocellular carcinoma before surgery and prothrombin time are independent risk factors for 1-year survival， whereas a high HGB level is a protective factor for increasing 1-year survival. Preoperative comorbidities with hepatocellular carcinoma and ascites are independent risk factors for the long-term prognosis of patients with spontaneous portosystemic shunt and IGV-1 bleeding and can significantly shorten survival time. Preoperative comorbidity with ascites can reduce the occurrence of rebleeding， while postoperative hepatocellular carcinoma and aggravation of ascites after surgery are independent risk factors for rebleeding； aggravation of ascites after surgery is an independent risk factor for the development of ascites in the future.

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: To analyze the regulatory effect of Atractylodes macrocephala Koidz. extract on the immune function of mice, so as to provide a reference for the study of the mechanism of Atractylodes macrocephala Koidz. regulating immune function. Methods: Forty-eight SPF healthy male ICR mice were randomly divided into control group and low (0.5 g/kg), medium (2.0 g/kg), and high (4.0 g/kg) dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day. The delayed allergy test was performed for 28 consecutive days. Sixty SPF healthy male ICR mice were randomly divided into a control group, polyinosinic acid injection group (model group), and low, medium, and high dose groups, with 12 mice in each group. The mice in control group were given the pure water by gavage once a day, while the mice in each dose group were given the corresponding dose of Atractylodes macrocephala Koidz. extract by gavage once a day for 14 consecutive days. On days 13 and 14 of administration, the mice in the model group and each dose group were intraperitoneally injected with sterile polyinosinic acid solution to perform the immunosuppressive experiment induced by polyinosinic acid. The mouse ear pieces were weighed, and the thymus and spleen of the mice were weighed and stained with HE to calculate the pathological scores. Peripheral blood was collected for blood cell detection and T cell classification. Results: Mice in each group had normal feeding, activity, and growth status, and no abnormality was observed. In the delayed allergy test, compared with the control group, the degree and rate of ear swelling in the low, medium and high dose groups were higher, the white blood cell count in the medium dose group was higher, and the absolute values of lymphocytes in the low and medium dose groups were higher (all P<0.05). Compared with the control group, the pathological scores of the thymus and spleen in the model group were higher (both P<0.05). In the immunosuppressive experiments in mice induced by polyinosinic acid, compared with the model group, the pathological score of the thymus in the high dose group was lower (P<0.05), and the boundary between the thymus cortex and medulla was improved. Conclusions Atractylodes macrocephala Koidz. extract can increase the degree of ear swelling and peripheral blood white blood cell count in mice. High dose of Atractylodes macrocephala Koidz. extract can improve the thymus injury induced by polyinosinic acid, and has an immunomodulatory effect.

Objective: To investigate the trend in disease burden of injuries among children and adolescents in China from 1990 to 2021, so as to provide a basis for formulating prevention and control strategies and reducing this disease burden. Methods: Data on mortality, disability-adjusted life years (DALY) rate, incidence, and prevalence of injuries among children and adolescents aged <20 years in China from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. All rates were standardized using the GBD 2021 world standard population. The trend in incidence of disease burden of injuries among children and adolescents across differents genders and ages from 1990 to 2021 was evaluated using average annual percent change (AAPC). Results: From 1990 to 2021, the standardized mortality (AAPC=-5.435%), standardized DALY rate (AAPC=-5.311%), standardized incidence (AAPC=-0.466%), and standardized prevalence (AAPC=-0.810%) of injuries among children and adolescents in China showed downward trends (all P<0.05). Among these, the standardized mortality of animal contact (AAPC=-9.138%) and the standardized DALY rate of medical side effects (AAPC=-8.389%) decreased at a relatively fast pace, while the standardized incidence of falls (AAPC=0.083%) and the standardized prevalence of exposure to natural forces (AAPC=2.656%) showed upward trends (all P<0.05). The standardized mortality, standardized DALY rate, standardized incidence and standardized prevalence of injuries were higher in males than in females. The trend in males showed a downward trend (all P<0.05), consistent with the total population. The crude incidence of injuries in the group aged 15-<20 years showed an upward trend (AAPC=0.391%, P<0.05), while the trend in the group aged 10-<15 years was not statistically significant (P>0.05). The crude incidence of injuries in the groups aged 5-<10 years and <5 years showed downward trends (AAPC=-0.488% and -2.275%, both P<0.05). In 2021, the <5 years age group had the highest crude mortality and crude DALY rate of injuries, at 13.94/100 000 and 1 257.26/100 000, respectively. The 15-<20 years age group exhibited the highest crude incidence and crude prevalence, at 4 874.05/100 000and 4 050.35/100 000, respectively. Drowning and falls were major components of the disease burden across all age groups. Conclusions From 1990 to 2021, the disease burden of injuries among children and adolescents in China showed an overall downward trend. The disease burden was consistently higher in males than in females. Children aged <5 years face a high risk of fatality and disability, while adolescents aged 15-<20 years experience a high incidence and frequency of injuries. Drowning and falls were key priorities for prevention and control.

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.

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 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.
