Objective: To investigate the factors influencing the co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia, so as to provide a data foundation and theoretical basis for developing targeted intervention measures. Methods: In September and October 2024, a stratified cluster random sampling method was employed to select 139 102 students from 539 schools across 12 leagues/cities and 103 banners/counties in Inner Mongolia Autonomous Region. Participants who were diagnosed with allergic rhinitis by a doctor at least once within one year and had a body mass index ≥ 28 kg/m 2 were considered to have comorbid conditions. Results: The coprevalence rate of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia was 6.4% (8 931 cases). Lasso-Logistic regression revealed that nonboarding status, higher maternal education, consuming high protein foods ≥1 time daily, occasionally or never eating breakfast, engaging in moderate to vigorous physical activity for ≥60 minutes on fewer than half of holidays, and having been exposed to second hand smoke in person within the past seven days were associated with higher odds ratios for co-prevalence of allergic rhinitis and obesity( OR = 1.23 , 1.22-1.63, 1.20, 1.19, 1.38, 1.35); being female, higher grade level, residence in flag/county/district areas, non only child status, never having consumed a full glass of alcohol, non hypertensive status, and households without pets were associated with lower co-prevalence risks ( OR =0.65, 0.67-0.77, 0.81, 0.87, 0.73, 0.41, 0.68) (all P <0.05). The ROC curve indicated an area under the curve of 0.64 for the predictive model, demonstrating satisfactory discriminatory ability. The calibration curve showed consistency between predicted and actual occurrence probabilities. Conclusions The co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia is closely associated with demographic characteristics, dietary behaviours, and lifestyle habits. Future prevention and control strategies should prioritize these factors to implement targeted interventions.

OBJECTIVE To conduct a systematic review concerning the safety of using glucagon-like peptide-1 receptor agonists （GLP-1RA） before gastrointestinal endoscopy. METHODS Chinese and English databases including CNKI， Wanfang Data， VIP， CBM， and PubMed were searched to collect systematic reviews and meta-analyses on the safety of using GLP-1RA before gastrointestinal endoscopy， with a search period from the inception to September 30， 2025. Report quality， methodological quality， risk of bias， and evidence quality were assessed using the PRISMA 2020 statement， AMSTAR 2 scale， ROBIS tool， and GRADE tool， respectively. Corrected covered area （CCA） was used to quantitatively evaluate the degree of outcome overlap， and a comprehensive quality analysis was performed on the quantitative results of systematic reviews/meta-analyses. RESULTS Ten studies were included. All 10 stu dies had some information deficiencies （15.5-19.5 points）， and were at high risk of bias； 9 studies were extremely low methodological quality， while 1 study was low. In terms of evidence quality， among 88 outcome indexes， there was 1 moderate-level index， 28 low-level indexes， and 59 extremely low-level indexes. The CCA values of the incidence of residual gastric contents， aspiration， endoscopy interruption， repeated endoscopy， inadequate bowel preparation and Boston Bowel Preparation Scale scores were 37.30%， 35.00%， 35.00%， 50.00%， 29.60% and 20.00%， respectively. Results of comprehensive quality analysis showed that compared with the control group， the incidence of residual gastric contents， endoscopy interruption and repeated endoscopy were increased significantly in the intervention group， along with a notably prolonged gastric emptying time and a significantly lower score of Boston Bowel Preparation Scale （ P ＜0.05）. However， the study results regarding the effects of GLP-1RA on the incidence of aspiration and inadequate bowel preparation were inconsistent. CONCLUSIONS The use of GLP-1RA before gastrointestinal endoscopy can increase certain safety risks， including residual gastric contents， endoscopy interruption and repeated endoscopy， prolong gastric emptying time， and reduce the quality of bowel preparation. However， the effects on aspiration and inadequate bowel preparation remain controversial. The reports included in systematic reviews/meta-analyses exhibited low quality in reporting， methodology and evidence， with high risk of bias. Therefore， conclusions should be interpreted with caution.

This study was a single-center retrospective study, to investigate the correlation between the relative level of miR-200a in exfoliated cells of peritoneal dialysis (PD) effluent and clinical indicators of peritoneal function in PD patients. Clinical data of PD patients who underwent treatment in the Department of Nephrology, the First Affiliated Hospital of Nanchang University, from January 2024 to December 2024 were collected, and the relative level of miR-200a in exfoliated cells of PD effluent was assessed. Patients were divided into three groups according to dialysis duration (Group A:≤1 year; Group B:>1 to <5 years; Group C:≥5 years), and differences in clinical data among the groups were compared. The correlation between the relative level of miR-200a and serum albumin, serum calcium, serum phosphorus, serum creatinine, hemoglobin, the neutrophil/high-density lipoprotein cholesterol ratio, the monocyte/high-density lipoprotein cholesterol ratio, the lymphocyte/high-density lipoprotein cholesterol ratio, and 24-hour urine volume in PD patients was analyzed. The results showed that there were no statistically significant differences among the three groups in gender, age, creatinine clearance rate, or Kt/V (all P>0.05). However, statistically significant differences were found among the three groups in peritoneal transport type ( χ2=13.518, P=0.001) and ultrafiltration volume ( H=6.905, P=0.032). Based on the 4-hour PD effluent creatinine/blood creatinine in the peritoneal equilibration test, patients were divided into the low transporter/low average transporter group (L group) and the high transporter/high average transporter group (H group). A statistically significant difference in the relative level of miR-200a was observed between the two groups [11.70 (1.09, 20.49) vs. 0.73 (0.46, 1.98), t=4.545, P<0.001]. The relative level of miR-200a was positively correlated with ultrafiltration volume and 24-hour urine output ( r=0.328, P=0.030; r=0.516, P<0.001), and negatively correlated with dialysis vintage ( r=-0.496, P<0.001). These results indicate that miR-200a level in PD effluent may, to some extent, reflect patients' peritoneal membrane function.

Increasing evidence shows that the early lesions of Parkinson's disease (PD) originate from gut, and correction of microbiota dysbiosis is a promising therapy for PD. FLZ is a neuroprotective agent on PD, which has been validated capable of alleviating microbiota dysbiosis in PD mice. However, the detailed mechanisms still need elucidated. Through metabolomics and 16S rRNA analysis, we identified glycoursodeoxycholic acid (GUDCA) was the most affected differential microbial metabolite by FLZ treatment, which was specially and negatively regulated by Clostridium innocuum, a differential microbiota with the strongest correlation to GUDCA production, through inhibiting bile salt hydrolase (BSH) enzyme. The protection of GUDCA on colon and brain were also clarified in PD models, showing that it could activate Nrf2 pathway, further validating that FLZ protected dopaminergic neurons through promoting GUDCA production. Our study uncovered that FLZ improved PD through microbiota-gut-brain axis, and also gave insights into modulation of microbial metabolites may serve as an important strategy for treating PD.

Although enteric glial cell (EGC) abnormal activation is reported to be involved in the pathogenesis of Parkinson's disease (PD), and inhibition of EGC gliosis alleviated gut and dopaminergic neuronal dysfunction was verified in our previous study, the potential role of gut microbiota on EGC function in PD still need to be addressed. In the present study, fecal microbiota transplantation revealed that EGC function was regulated by gut microbiota. By employing 16S rRNA and metabolomic analysis, we identified that 3-indolepropionic acid (IPA) was the most affected differential microbial metabolite that regulated EGC gliosis. The protective effects of IPA on PD were validated in rotenone-stimulated EGCs and rotenone (30 mg/kg i.g. for 4 weeks)-induced PD mice, as indicated by decreased inflammation, improved intestinal and brain barrier as well as dopaminergic neuronal function. Mechanistic study showed that IPA targeted pregnane X receptor (PXR) in EGCs, and inhibition of IL-13Rα1 involved cytokine-cytokine receptor interaction pathway, leading to inactivation of downstream JAK1-STAT6 pathway. Our data not only provided evidence that EGC gliosis was critical in spreading intestinal damage to brain, but also highlighted the potential role of microbial metabolite IPA in alleviating PD pathological damages through gut-brain axis.

Objective: To analyze the prevalence trends of different types of elevated blood pressure and their association with nutritional status among primary and secondary school students in Inner Mongolia from 2019 to 2024, providing references for targeted prevention strategies. Methods: From September 2019 to 2024, a stratified random cluster sampling method was used to select 12 primary and secondary schools from each league city in Inner Mongolia Autonomous Region. A total of 177 108, 137 758, 190 182, 180 084 , 188 056, 180 351 primary and secondary school students (excluding grades one to three of primary school) were included for physical examination. The correlation between their nutritional status and high blood pressure was analyzed based on the basic situation of 129 821 primary and secondary school students who completed a questionnaire survey at the same time in 2024. Statistical analysis was conducted using a Chi-square test and multiple Logistic regression model. Results: From 2019 to 2024, the detection rates of elevated blood pressure were 13.60%, 13.68%, 17.60%, 17.24%, 14.77% and 15.96%, respectively. The rates for isolated systolic hypertension were 4.24%, 5.83%, 7.26%, 7.19%, 6.24% and 6.93%; isolated diastolic hypertension rates were 6.38%, 4.99%, 6.23 %, 6.41%, 5.39% and 5.66%; and combined systolic and diastolic hypertension rates were 2.97%, 2.86%, 4.11%, 3.65%, 3.14 % and 3.36%. Multivariate Logistic regression analysis showed that girls, junior high school, senior high school, overweight, and obesity were positively associated with elevated blood pressure risk ( OR =1.27, 1.25, 1.32, 1.66, 3.07, all P <0.05); conversely, county residence, Mongolian ethnicity, and other ethnicities showed negative associations ( OR =0.90, 0.93, 0.90, all P <0.05). Conclusions Overweight and obesity among children and adolescents are closely related to various types of elevated blood pressure. Prevention strategies should prioritize effectively controlling weight issues among children and adolescents, thereby effectively reducing the incidence of elevated blood pressure.

Objective To evaluate the applicability and guideline concordance of the Chinese Society of Clinical Oncology(CSCO)arti-ficial intelligence(AI)system in clinical decision-making for colorectal cancer(CRC)patients,and to explore its feasibility in real-world clinical applications.Methods A total of 972 CRC patients diagnosed and treated at the Second Affiliated Hospital,Zhejiang University School of Medicine,from January 2010 to December 2021,were included.Patient data were analyzed by the CSCO AI system to gener-ate treatment decisions,and decision concordance was assessed by a blinded independent central review(BICR)panel.The applicability and guideline concordance rates of the CSCO AI system were calculated for different treatment stages,and a logistic regression model was used to analyze factors influencing the system's decision discrepancies with actual treatments.Results The overall applicability rate of the CSCO AI system was 96.2%,and the overall guideline concordance rate was 94.9%.In the adjuvant and palliative treatment stages,the system's applicability rates were 95.8%and 96.7%,respectively,and the guideline concordance rates were 95.0%and 94.9%,respective-ly.Multivariate logistic regression analysis showed that age≥65 years and high-risk stage Ⅱ treatment were significant factors affecting guideline concordance in the adjuvant treatment stage(both P<0.05).Conclusions The CSCO AI system demonstrated high applicability and guideline concordance in the adjuvant and palliative treatment stages for CRC.The system's clinical decision-making potential is sig-nificant,and it can be further optimized for specific clinical scenarios and promoted for use across various medical institutions.

Objective To explore the clinical effect of using the Brisson technique combined with a precise measurement scheme in the treatment of hidden penis.Methods The clinical data of 120 children with hidden penis treated in our hospital from January 2021 to June 2024 were retrospectively analyzed.The enrolled children were randomly divided into the study group(n=60)and the control group(n=60).The study group was treated with the Brisson technique combined with a precise measurement scheme,and the cutting of the penile skin was designed according to the data.The control group was treated with the traditional Devine technique.The surgical effects,penile lengths before and after surgery,and the incidence of postoperative complications of the children in the two groups were compared and analyzed.Results The effective rate of the study group reached 100％,which was significantly higher than that of the control group(93％,P＜0.05).Six months after surgery,the penile length of the children in the study group was longer than that in the control group,and the difference was statistically significant(P＜0.05).The incidence of surgical complications in the study group was 5％,which was significantly lower than that in the control group(17％,P＜0.05).Conclusion Using the Brisson technique combined with a precise measurement scheme to treat hidden penis has a good effect,a high effective rate,and a low incidence of complications.

AIM:Regulatory T cells(Tregs)are a specialized subset of CD4+T cells primarily involved in im-munosuppressive functions.AMP-activated protein kinase(AMPK)serves as a metabolic sensor that governs the differen-tiation,maturation,and immune functions of Tregs through metabolic reprogramming.However,the impact of AMPKα1(the catalytic subunit of AMPK)knockout specifically in Tregs on the host's immune microenvironment remains largely un-explored.METHODS:Histological changes in immune organs were assessed using HE staining.The types of immune cells and their relative population percentages in immune organs and blood were quantified through flow cytometry in both AMPKα1flox/flox(AMPKα1fl/fl)mice and Treg-specific AMPKα1 knockout mice(AMPKα1fl/flFoxp3cre mice).RESULTS:Compared to AMPKα1fl/fl mice,the percentage of eosinophils in the bone marrow of AMPKα1fl/flFoxp3cre mice was significant-ly reduced.Additionally,while the thymus of AMPKα1fl/flFoxp3cre mice exhibited normal structure,both its size and the ra-tio of thymus weight to body weight were significantly decreased.The knockout of AMPKα1 in Tregs led to a notable reduc-tion in the total percentage of immature double-negative(DN)cells.Consequently,the percentage of CD4+T cells derived from these DN cells also decreased,even though the percentages of DN1 and DN4 cells were higher in the thymus of AMPKα1fl/flFoxp3cre mice compared to AMPKα1fl/fl mice.Importantly,the proportion of Siglec-F+CD11b+eosinophils in the thymus was significantly lower in AMPKα1fl/flFoxp3cre mice.Knockout of AMPKα1 in Tregs resulted in a marked increase in the percentage of CD4+T cells in peripheral blood,alongside a decrease in the proportion of mature CD8+T cells.Similar-ly,the proportion of CD4+T cells in the spleen of AMPKα1fl/flFoxp3cre mice was elevated compared to AMPKα1fl/fl mice.In contrast,the proportion of neutrophils significantly decreased,while mononuclear cell proportions increased in the spleen of AMPKα1fl/flFoxp3cre mice.In lymph nodes,the medullary boundaries in AMPKα1fl/flFoxp3cre mice were blurred,and the lymphoid follicles were missing,a feature not observed in AMPKα1fl/fl mice.Furthermore,the knockout of AMPKα1 in Tregs reduced the CD3+T cell population,particularly the CD8+T cell population,in lymph nodes.Although the mature Treg cell population was significantly lower in AMPKα1fl/flFoxp3cre mice,the percentage of CD4+T cells was markedly in-creased.In contrast,there was no statistically significant difference in granulocyte populations between AMPKα1fl/flFoxp3cre and AMPKα1fl/fl mice.CONCLUSION:The populations of mature Tregs,CD8+T cells and eosinophils in various im-mune organs were significantly altered in mice with Treg-specific AMPKα1 knockout,suggesting a potential remodeling of the host immune microenvironment in response to inflammatory stimuli.
