OBJECTIVE To investigate the effects of baicalin （BC） on insulin resistance in rats with gestational diabetes mellitus （GDM） and its underlying mechanism based on the adenosine monophosphate-activated protein kinase （AMPK）/suppressor of variegation 3-9 homolog 1 （SUV39H1）/histone H3 lysine 9 trimethylation （H3K9me3） axis. METHODS A GDM rat model was established by a combination of a high-fat diet and streptozotocin injection. The successfully modeled rats were divided into the GDM group， BC low-dose group， BC high-dose group， and high-dose of BC+AMPK inhibitor （Compound C） group， with 10 rats in each group. Another 10 pregnant rats fed a normal diet served as the control group. Rats in each group were given corresponding drugs/normal saline intragastrically and/or intraperitoneally， once daily for 2 consecutive weeks. After the last administration， the levels of fasting blood glucose （FBG）， pancreatic function indexes [fasting insulin （FINS）， homeostasis model assessment of insulin resistance （HOMA-IR）， insulin sensitivity index （ISI）]， blood lipid indexes （total cholesterol， triglyceride， low-density lipoprotein cholesterol）， liver function indexes （alanine transferase， aspartate transferase， alkaline phosphatase）， inflammatory indicators （C-reactive protein， interleukin-1β， interleukin-6）， metabolic regulatory protein [complement-C1q/tumor necrosis factor-related protein 3 （CTRP3）]， insulin sensitivity related factors [glucose transporter 4 （GLUT4）， adiponectin]， and oxidative stress indicators [superoxide dismutase （SOD）， catalase （CAT）， malondialdehyde （MDA）] were measured. Pathological changes in liver tissue were observed， and the expressions of proteins related to the AMPK/SUV39H1/H3K9me3 axis in liver tissue were detected. RESULTS Compared with the GDM group， rats in the BC low- and high-dose groups showed varying degrees of improvement in pathological changes such as disordered cell arrangement， vacuolar degeneration， lipid deposition， and inflammatory cell infiltration in liver tissue. Their FBG and FINS levels， HOMA-IR， the levels of blood lipid indexes， liver function indexes， inflammatory indicators and MDA， and the expressions of SUV39H1 and H3K9me3 were significantly decreased or down-regulated， while metabolic regulatory protein， insulin sensitivity-related factors and AMPK protein phosphorylation levels were significantly increased （ P ＜0.05）. The improvement was more significant in the BC high-dose group （ P ＜0.05）. Compound C could significantly reverse the ameliorative effects of high-dose BC on the above quantitative indicators （ P ＜0.05）. CONCLUSIONS BC can significantly reduce oxidative stress and inflammatory responses， increase serum levels of CTRP3， GLUT4 and adiponectin， thereby improving insulin resistance in GDM rats. These effects may be related to the activation of AMPK and inhibition of SUV39H1-mediated H3K9me3 modification.

Objective To explore the role and potential mechanism of Astragali Radix-derived extracelluar vesicles(EVs)-like particles(AR-EVLP)in diabetic wound healing,providing a novel therapeutic drug mode and theoretical basis for traditional Chinese medicine in treating diabetic skin ulcers.Methods AR-EVLP was extracted using ultracentrifugation.Untargeted metabolomics was used to analyze the potential active components of AR-EVLP,and the main active substances in AR-EVLP were identified by comparison with the Herb database.The targets of the active components were obtained through the Swiss Target Prediction database and the TCMSP database.Targets related to diabetic wound healing were obtained from the GeneCards database.Key targets were identified by intersecting drug targets and disease targets.GO functional annotation and KEGG pathway enrichment analysis were performed using the DAVID database.Based on the pathway enrichment results,a"drug components-targets-pathways"diagram was constructed to identify core targets.Molecular docking and visualization were performed using Autodock and PyMOL software.Results Formononetin was identified as the main active component in AR-EVLP,with 66 key targets related to diabetes and wound healing,including 15 key node proteins such as SRC,CASP3 and JUN.GO functional enrichment analysis suggested that formononetin can regulate biological processes such as protein phosphorylation and gene expression.KEGG pathway enrichment analysis indicated potential involvement in multiple signaling pathways,including VEGF and TNF.Seven targets,including PIK3CA,JUN and MAPK14,were identified as core targets for formononetin.Molecular docking showed that formononetin had the strongest binding affinity with MAPK14.Conclusion AR-EVLP may be a potential effective drug mode for the treatment of diabetic wound healing.

The incidence of delayed chemotherapy-induced nausea and vomiting is relatively high among pediatric cancer patients. Nausea and vomiting symptoms can exacerbate physical and psychological burdens, potentially leading to aversion and reduced treatment adherence. This paper analyzes and summarizes delayed chemotherapy-induced nausea and vomiting in pediatric cancer patients, covering overview, influencing factors, assessment tools, and non-pharmacological interventions, aiming to provide insights for clinical prevention and intervention strategies targeting delayed chemotherapy-induced nausea and vomiting in pediatric patients.

Diabetes is a chronic disease that requires lifelong medication and long-term management. The longer the duration of the disease, the more likely it is to lead to progressive chronic complications affecting the eyes, kidneys, nervous system, and cardiovascular system. These complications may result in gradual functional decline or even organ failure, and may also trigger severe acute metabolic disorders. The cumulative financial burden on patients and their families can be substantial, giving rise to what is known as financial toxicity, which in turn may negatively affect patients' health outcomes. This review comprehensively explores the concept of financial toxicity in diabetic patients, including its assessment tools, influencing factors, and coping strategies. It also offers targeted suggestions aimed at informing the development of more scientific and effective systemic interventions, with the ultimate goal of improving treatment outcomes and quality of life for individuals living with diabetes.

Intraoperative neural monitoring (IONM) combines electrophysiology with anatomy to monitor nerve function during thyroid surgery,and has become an important auxiliary technology for neuroprotection. After more than ten years of development,the technology has been widely applied and popularized in China,promoting the development of a number of new technologies in the industry. Combined with the questionnaire survey data of the Chinese Neural Monitoring Study Group,this paper aims to summarize the clinical effect of IONM technology, the application status and existing problems at home and abroad, and propose the possible future development direction.

Objective To investigate the relationship between vertical laminar fracture(VLF)in thoracolumbar burst fractures and both neurological injury and dural tear.Methods A retrospective analysis was conducted on the clinical data and multi spiral computed tomography(MSCT)coronal images of 255 patients of thoracolumbar burst fractures.The patients were divided into three groups based on the presence of VLF[Ⅰ group(complete VLF group),Ⅱ group(partial VLF group),and Ⅲ group(normal lamina group)].Statistical analysis was performed using analysis of variance and Fisher's exact test to compare radiological parameters,inci-dence of dural tear,and neurological injury among the groups.Results The Ⅰ group showed significant differences in spinal canal sagittal diameter,pedicle distance,and spinal canal area compared with the other two groups(P<0.05).However,there was no sig-nificant difference in vertebral body compression rate between the Ⅰ group and the Ⅱ group(P>0.05).The Ⅰ group had the high-est incidence of severe neurological injury[American Spinal Injury Association(ASIA)impairment scale grades A and B]and dural tear(P<0.05).Conclusion The severity of VLF is closely related to dural tear and neurological injury.MSCT coronal images can clearly display the extent of VLF,providing an important basis for clinical evaluation and treatment plan.

Objective:To investigate the risk factors for dural tears in patients with thoracolumbar burst fracture (TLBF) and their predictive efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 135 TLBF patients admitted to Tianjin Fifth Central Hospital from March 2020 to February 2025, including 83 males and 52 females, aged 16-65 years [41(31, 50)years]. Among them, 31 patients had thoracic fracture and 104 lumbar fracture. The patients were divided into dural tear group ( n=82) and dural intact group ( n=53) based on the presence of dural tear. The following data of the two groups were collected including gender, age, underlying diseases, body mass index (BMI), bone density T-score, cause of injury, AO fracture classification, distribution of injured vertebrae, vertical laminar fracture (VLF) classification, radiological parameters (pedicle spacing, vertebral canal area, sagittal diameter of the vertebral canal, vertebral compression rate), and American Spinal Injury Association (ASIA) impairment scale. Univariate analysis and multivariate Logistic regression analysis were conducted to assess and identify the independent risk factors for dural tears in TLBF patients. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the predictive efficacy of each independent risk factor. Results:Univariate analysis showed statistically significant differences in VLF classification, pedicle spacing, vertebral canal area, sagittal diameter of the vertebral canal, vertebral compression rate, and ASIA impairment scale between the two groups ( P<0.05). Multivariate Logistic regression analysis revealed that VLF classification ( OR=4.16, 95% CI 1.03, 11.46, P<0.05), pedicle spacing ( OR=1.08, 95% CI 0.81, 1.16, P<0.05), and ASIA impairment scale ( OR=3.06, 95% CI 2.00, 8.48, P<0.01) were significantly associated with dural tears in TLBF patients. ROC curve analysis showed that VLF classification (AUC=0.86, 95% CI 0.62, 0.95), pedicle spacing (AUC=0.86, 95% CI 0.77, 1.00), and ASIA impairment scale (AUC=0.76, 95% CI 0.74, 0.97) had relatively high predictive efficacy for dural tear. The combination of VLF classification and pedicle spacing had the highest predictive efficacy (AUC=0.89, 95% CI 0.78, 1.01). Conclusions:VLF classification, pedicle spacing, and ASIA impairment scale are independent risk factors for dural tears in TLBF patients. VLF classification and pedicle spacing have relatively high independent predictive efficacy and their combination can further improve the predictive efficacy.
