ObjectivePatients with hepatic glycogen storage disease(GSD)have recurrent episodes of hypoglycemia. This study aimed to investigate and analyze blood glucose and biochemical indicators in pediatric patients with hepatic GSD, thus provide data support for hypoglycemia prevention and its clinical management. MethodsA cross-sectional field study was conducted among patients with hepatic GSD treated in the Department of Pediatrics of Guangdong Provincial People's Hospital on July 14, 2024. We collected the peripheral blood samples of the patients and their healthy family controls on site, then analyzed and compared their blood glucose and biochemical indicators. ResultsOf the 44 patients with hepatic GSD, there were 34 males and 10 females, including GSD Ib(n =14), GSD Ia(n=15), GSD Ⅲ(n=2), GSD Ⅵ(n=7)and GSD Ⅸ(n=6). The average age was 7.60(5.08-11.98)years. All patients were on uncooked cornstarch(UCCS)therapy. Of the patients, 77.3%(34/44)had hepatomegaly, 61.4%(27/44)had recurrent hypoglycemia, 61.4%(27/44)had blood glucose ≤ 3.9 mmol/L, 18.2%(8/44)had blood glucose ≤ 2.8 mmol/L, and none of the 8 cases was GSD Ib. The lowest blood glucose level was 1.19 mmol/L and no episodes of hypoglycemia occurred. Of the family control subjects, 65.9%(29/44)had blood glucose ≤ 3.9 mmol/L. There was no significant difference in hypoglycemia prevalence between hepatic GSD group and control group(P=0.658). The hepatic GSD patients had hyperlactacemia, hyperuricemia and hypercholesterolemia prevalence rates of 65.9%, 45.5% and 9.1%, respectively, as compared with 18.2%, 43.2% and 15.9%, respectively, for the family control subjects. No significant difference was found in the prevalence rates of hyperuricemia and hypercholesterolemia between the two groups(P=0.830 and P=0.334, respectively). ConclusionsAsymptomatic hypoglycemia is common in patients with hepatic GSD, especially in non-GSD-Ib patients. It is necessary to optimize the diet management of UCCS, conduct dynamic blood glucose monitoring and follow a light diet, so as to decrease hyperuricemia and hypercholesterolemia, avoid and reduce the serious adverse reactions and complications caused by severe hypoglycemia.

ObjectiveTo investigate the demyelination induced by Angiostrongylus cantonensis (AC) infection in the brain of Balb/c mice and analyze the untargeted metabolomic changes in the corpus callosum, aiming to elucidate the underlying mechanisms. MethodsBalb/c mice were randomly assigned to a control group (n=6) and an infection group (n=6). The infection group was orally administered 30 third-stage larvae of AC, while the control group received an equal volume of saline. Body weight, visual function, and behavioral scores were measured on post-infection 3, 6, 9, 12, 15, 18, and 21 days to assess neurological alterations. After 21 days, brain tissues were harvested for immunofluorescence staining, hematoxylin-eosin (HE) staining, and transmission electron microscopy to examine morphological changes in brain myelin and retina. Metabolomics analysis was performed, and differential metabolites were identified using volcano plots and heatmaps. The distribution of fold changes and bar charts were used to profile the key metabolites. These differential metabolites were then subjected to Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and regulatory network analysis. ResultsOn the 9th day after AC infection, Balb/c mice showed a decline in neurological behavioral scores (P<0.05). By day 15, visual scores decreased (P<0.05), and by day 21, significant weight loss (P<0.001) and mortality were observed. Concurrently, transmission electron microscopy and immunofluorescence staining revealed significant myelin damage in the corpus callosum and a marked reduction in oligodendrocytes (P<0.001). HE staining showed severe retinal ganglion cell damage. Metabolomic analysis revealed that glycerophospholipids were the most abundant differential metabolites, with steroids and sphingolipids being relatively less abundant. Cholesteryl ester CE (20:2) was significantly upregulated (P<0.001), while phosphatidylmethanol (18:0_18:1) was significantly downregulated (P<0.01). KEGG enrichment and regulatory network analyses demonstrated that the differential metabolites were mainly enriched in metabolic pathways like steroid biosynthesis, bile secretion, and cholesterol metabolism, and were involved in key metabolic pathways such as sphingolipid metabolism, neural signal regulation, and glycerophospholipid metabolism. ConclusionsAC infection affects the metabolic state of mice via multiple pathways, modifying the levels of metabolites crucial for myelination and myelin stability. Demyelination may be closely linked to the disruption of these key metabolic pathways, particularly the dysregulation of cholesterol and sphingolipid metabolism, potentially playing a central role in demyelination onset. Furthermore, alterations in phospholipid metabolism and abnormal nerve signaling regulation may exacerbate myelin damage.

The discussion on the connotation of children’s subjectivity is not only a response to the lack of children’s subjectivity at the current stage of health management, but also a reference for children’s medical science popularization. Based on the perspective of social critical theory, this study used empirical research methods to review the "Dream Medical College" project of Children’s Hospital of Fudan University. The current situation and influencing factors of health management experience of 1 520 children participating in the "Dream Medical College" project were analyzed. The study showed that 96.35% of 1 316 subjects had diagnosis and treatment experience in specialized hospitals, and the overall negative emotional performance was at a low level (0~12 points). There was significant correlation between diagnosis and treatment, invasive experience and children’s emotional performance (P<0.05). The study revealed that the diagnosis and treatment field is the main practice place of children’s health management, while the subjective of children with different diagnosis and experience perform significantly different. Children over 4 years old have better language anxiety than physical anxiety when receiving diagnosis and treatment. Although medical science popularization is an important practical form of children’s health management, it lacks the science popularization content of invasive diagnosis and treatment and emotional management, and creative popular science form is more suitable for children with long-term and frequent diagnosis and treatment experience.

OBJECTIVE
To explore the pharmacodynamic related substances and mechanism of Weining San(WNS) against gastric ulcer(GU) according to fingerprint and network pharmacology.
METHODS
Twelve batches of WNS fingerprints were established by HPLC, and methodological investigation was carried out. Combined with reference substances, characteristic peaks were identified, pharmacodynamic related substances were screened, and network pharmacological analysis was carried out. Using TCMIP and Swiss Target Prediction database to retrieve component targets; Using OMIM, GeneCards and Drugbank databases to retrieve GU disease targets, taking the intersection targets of components and diseases, using String database to construct protein-protein interaction network diagram, and analyzing topological parameters; Using Cytoscape 3.8.2 software to construct "component-disease-target" network diagram; GO and KEGG enrichment analysis of intersection targets were carried out by Metascape website. Then the alcoholic GU mouse model was established by intragastric administration of absolute ethanol to verify the results of network pharmacology prediction. RESUITS The precision, stability and repeatability of HPLC fingerprint method were good. By comparison and comprehensive analysis of control substances, notoginsenoside R1, ginsenoside Rg1, militarine, ginsenoside Rb1, schisandrin, schisandrol B, deoxyschizandrin and schisantherin A were identified as pharmacodynamic related substances in WNS, which may play their role by regulating core targets such as AKT1, IL-6, STAT3, TNF, IL1B and key signal pathways such as PI3K-Akt and JAK-STAT. The gastric ulcer index, ulcer inhibition rate and HE staining showed that WNS could improve gastric mucosal injury in GU mice. The results of ELISA, WST-1 and TBA showed that WNS could decrease the levels of TNF-α, IL-6, IL-1β and MDA, and increase the levels of SOD and PGE2, suggesting that the anti-GU effect of WNS was related to the inhibition of inflammatory reaction and oxidative stress mechanism, which further verified the prediction of network pharmacology.
CONCLUSION
This study combines fingerprint analysis, network pharmacology, and animal experimental validation to explore the pharmacodynamic related substances and mechanisms of WNS anti-GU efficacy, providing reference for quality control and clinical research of WNS.
