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 detection rate of CTX/CRO-R-KPN in neonates was the highest（57.1%），which was significantly higher than that in children，adults and the elderly（ χ2=46.141，38.843 and 32.093， P<0.001），and the detection rate in the elderly was higher than that in children and adults（ χ2=13.604 and 13.471， P<0.001）. The detection rates of MRSA and MRCNS were the highest in children（42.8% and 77.8%，respectively），which were higher than those in adults（ χ2=21.766 and 10.704， P<0.001）. Except MRSA and vancomycin-resistant Enterococcus faecium and faecalis，the detection rates of major drug-resistant bacteria in tertiary hospitals were higher than those in secondary hospitals（ P<0.05 or <0.01）. Conclusion:In 2023，the situation of antimicrobial resistance in Anhui province was serious，especially in northern and central Anhui，and targeted drug resistance control measures should be taken according to the monitoring results. At the same time，it is necessary to pay attention to the bacterial resistance in the elderly，newborns and children，and strengthen the rational use of antibiotics by clinicians to curb the spread of drug-resistant bacteria.

Aim To investigate the effect of CDR132L(miR-132 antisense oligonucleotide)on vascular remode-ling and function in mice with hypertension and hyperlipidemia,and explore its possible mechanism.Methods A total of 30 8-week-old male C57BL/6 mice were randomly divided into three groups:control group,model group and CDR132L group,with 10 mice in each group.The control group received with a standard diet while the model group and CDR132L group received N-nitro-L-arginine methyl ester(L-NAME)and high-fat diet to induce hypertension and hyperlip-idemia.The CDR132L group was administered with intraperitoneal injection of CDR132L at a dose of 20 mg/kg once weekly for six consecutive weeks,whereas the control group and the model group were given intraperitoneal injection of an equivalent volume of normal saline.The tail-cuff method was utilized for blood pressure measurement,blood lipid and glucose levels were assayed by an automatic biochemical analyzer,the thoracic aorta structure was observed by HE staining,endothelium-dependent relaxation of the thoracic aorta was evaluated by the vascular ring test,the expression level of miR-132 in the thoracic aorta was measured by qPCR,the protein expression levels of Gab1 and endothelial nitric oxide synthase(eNOS)in the thoracic aorta were determined by Western blot.Results Compared with the control group,the model group demonstrated notable rises in systolic and diastolic blood pressure,serum triglyceride,total cholesterol lev-els,and body weight.Moreover,the intima of thoracic aorta and the thickness of vascular wall was uneven,the smooth muscle cells of the tunica media were arranged irregularly,with a large amount of fat deposition in the vascular wall,and the endothelium-dependent relaxation response of thoracic aorta was decreased(P＜0.05).The expression level of miR-132 in the thoracic aorta was significantly increased(P＜0.05),while the expression level of Gabl and eNOS protein was markedly decreased(P＜0.05).Compared with the model group,the CDR132L group showed no significant differences in systolic and diastolic blood pressure,serum triglyceride and total cholesterol levels,as well as body weight(P＞0.05).However,the CDR132L group exhibited a complete and smooth intima of the thoracic aorta with minimal intravascular lipid deposition,the thickness of the vascular wall was uniform,the smooth muscle cells of the tunica media were arranged order-ly,accompanied by enhanced endothelium-dependent relaxation response of the thoracic aorta(P＜0.05).The expression level of miR-132 in the thoracic aorta was significantly decreased(P＜0.05),while the expression levels of Gab1 and eNOS protein were significantly increased(P＜0.05).Conclusion CDR132L can improve vascular remodeling and endothelium-dependent relaxation in hypertensive and hyperlipidemia mice,which may be related to the decrease of miR-132 expression level and the up-regulation of Gab1 and eNOS protein expression levels in the thoracic aorta.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To investigate the effect of quercetin on the aging model of bone marrow mesenchymal stem cells established under microgravity. Methods Using 3D gyroscope, a aging model of bone marrow mesenchymal stem cells was constructed, and after receiving quercetin and microgravity treatment, the anti-aging effect of the quercetin was evaluated by detecting related proteins and oxidation indexes. Results Compared to the control group, the expressions of age-related proteins p21, pi6, p53 and RB in the microgravity group significantly increased, while the expressions of cyclin D1 and lamin B1 significantly decreased, with statistical significance (P<0.05). In the microgravity group, mitochondrial membrane potential significantly decreased (P<0.05), ROS accumulation significantly increased (P <0.05), SOD content significantly decreased and MDA content significantly increased (P<0.05). Compared to the microgravity group, the expressions of age-related proteins p21, pi6, p53 and RB in the quercetin group significantly decreased, while the expressions of cyclin D1 and lamin B1 significantly increased, with statistical significance (P<0.05). In the quercetin group, mitochondrial membrane potential significantly increased (P<0.05), ROS accumulation significantly decreased (P<0.05), SOD content significantly increased and MDA content significantly decreased (P<0.05). Conclusions Quercetin can resist oxidation, protect mitochondrial function and normal cell cycle, thus delaying the aging of bone marrow mesenchymal stem cells induced by microgravity.

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.
