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.

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 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.

Hepatocellular carcinoma (HCC) expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming. Aldolase A (ALDOA) plays a prominent role in glycolysis; however, little is known about its role in HCC development. In the present study, we aim to explore how ALDOA is involved in HCC proliferation. HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout, which is consistent with ALDOA overexpression encouraging HCC proliferation. Mechanistically, ALDOA knockout partially limits the glycolytic flux in HCC cells. Meanwhile, ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase; ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function. A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun, and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells. In HCC patients, the expression level of ALDOA was correlated with the phosphorylation level of c-Jun (Thr93) and poor prognosis. Remarkably, hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models, and the knockdown of A ldoa strikingly decreased HCC development in vivo. Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription, opening additional avenues for anti-cancer therapies.

Objective : To explore whether chrysophanol(CHR) affects macrophage polarization by promoting mitochondrial biosynthesis through AMPK/PGC-1α pathway. Methods : The molecular docking and binding ability of CHR with AMPK and PGC-1α were predicted by Autodock vina software. Human monocytes(THP-1) were induced to M0 macrophages by phorbol myristate acetate(PMA), and to M1 macrophages by lipopolysaccharide(LPS) combined with interferon-γ(IFN-γ), which were set as Control group. M1 macrophages treated with CHR were set as CHR group. M1 macrophages treated with CHR combined with AMPK inhibitor(Compound C) were set as CHR+Compound C group. The mRNA expression levels of M1 macrophage markers(iNOS, CD86) and mitochondrial biosynthesis related genes(PGC-1α, NFR-1, TFAM) were detected by Quantitative real time polymerase chain reaction(qRT-PCR). The expression level of M1 macrophage marker iNOS was detected by immunofluorescence. The protein expression levels of AMPK, p-AMPK and PGC-1α were detected by Western blot. Results : The docking results showed that the binding energies of CHR with AMPK and PGC-1α were-8.4 kcal/mol and-7.4 kcal/mol, respectively. qRT-PCR results showed that the in vitro model of M1 macrophages was successfully established. Compared with the Control group, CHR treatment significantly increased the mRNA expression of mitochondrial biosynthesis-related genes PGC-1α, NFR-1, and TFAM(P<0.001). Compared with CHR treatment group, CHR combined with Compound C treatment significantly decreased the mRNA expression levels of mitochondrial biosynthesis-related genes PGC-1α, NFR-1, and TFAM(P<0.05). Immunofluorescence results showed that CHR treatment inhibited the protein expression of iNOS compared with the Control group(P<0.001). Compared with CHR treatment group,CHR combined with Compound C treatment reversed the inhibitory effect of CHR on i NOS protein expression(P<0.05). Western blot results showed that compared with the Control group,the CHR treatment group had significant increase in the protein expression levels of p-AMPK and PGC-1α(P<0.001).Compared with CHR treatment group,CHR combined with Compound C treatment significantly decreased the protein expression levels of p-AMPK and PGC-1α(P<0.05). Conclusion Chrysophanol may inhibit macrophage polarization to M1 by activating AMPK/PGC-1α signaling pathway to promote mitochondrial biosynthesis.

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 investigate the association of spleen volume with the risk of non-alcoholic fatty liver disease(NAFLD)as well as their causal relationship.Methods We included 90 NAFLD cases and 47 healthy controls who had received contrast-enhanced computed tomography(CT)scan of the abdomen at the Second Affiliated Hospital of Xi'an Jiaotong University from November 2022 to November 2023.We conducted three-dimensional reconstruction of the spleen through a deep learning network model using a two-stage coarse-to-fine segmentation approach.We compared the two groups using the two-sample t test or Mann-Whitney U test for continuous data and using the chi-square test for categorical data;evaluated the correlation between spleen volume and liver function indicators through Pearson correlation or Spearman rank correlation analyses;determined the factors influencing the development of NAFLD through multivariable Logistic regression analysis;and further assessed the casual relationship between spleen volume and NAFLD using the inverse variance-weighted two-sample Mendelian randomization(IVW-MR)method.Results Spleen volume was significantly larger in NAFLD cases than in controls(272.93±104.16 vs 204.37±81.20 cm3,P<0.001).The Spearman rank correlation analysis showed that spleen volume was positively correlated with the hepatic steatosis index(rs=0.422,P<0.001)and gamma-glutamyl transferase levels(rs=0.211,P=0.047)in patients with NAFLD.The multivariable Logistic regression analysis indicated that spleen volume was an independent risk factor for the development of NAFLD(odds ratio[OR]=1.01,95%confidence interval[CI]:1.00-1.02,P=0.049).The IVW-MR analysis detected a causal relationship between spleen volume and NAFLD(OR=1.16,95%CI:1.05-1.28,P=0.005).Conclusion Increased spleen volume may be a risk factor for the development and progression of NAFLD.Further studies are still needed to investigate the specific mechanism.

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.
