Neonatal diabetes mellitus （NDM） is a rare monogenic disorder primarily caused by insufficient insulin secretion resulting from mutations in the KCNJ11 and ABCC8 genes. Sulfonylureas， represented by glibenclamide， have become the standard therapy for this type of NDM by precisely closing the mutated ATP-sensitive potassium channels in pancreatic β cells， thereby restoring insulin secretion. Clinical studies confirm that sulfonylureas enable over 90% of patients to successfully transition from insulin to oral treatment， achieving long-term stable glycemic control and improving neurological outcomes to a certain extent. In terms of safety， severe hypoglycemia induced by sulfonylureas is relatively rare and gastrointestinal reactions are mild； moreover， sulfonylureas show good long-term tolerability， and have no adverse effects on child growth and development. In the future， by further refining the full-chain management pathway of “rapid genetic diagnosis-early intervention-specialized dosage forms-long-term follow-up”， the clinical application of sulfonylureas is expected to provide NDM patients with an optimized treatment regimen and maximize their health benefits.

ObjectiveTo investigate the mechanisms by which Huanglian Jiedutang （HLJDT） modulates microglial （MG） phenotypes through the sialic acid-binding Ig-like lectin 2 （SIGLEC2/CD22）/Src-homology-2-domain-containing protein tyrosine phosphatase-1 （SHP-1）/phosphorylated protein kinase B （p-Akt） signaling pathway， thereby promoting myelin repair and alleviating agitation-like behaviors in vascular dementia （VAD）. MethodsSixty C57BL/6J mice were randomly assigned to a sham （normal） group， model group， HLJDT low-， medium-， and high-dose groups （2.5， 5， and 10 g·kg^-1·d^-1）， and a risperidone group （2 mg·kg^-1·d^-1）， with 10 mice per group. VAD was induced by bilateral common carotid artery stenosis （BCAS）. From day 42， mice received drug interventions for 2 weeks. Agitation-like behaviors were assessed using the resident-intruder test. After behavioral testing， ventrolateral part of the ventromedial hypothalamus （VMHvl） tissues were collected. Western blot was used to measure protein levels of myelin oligodendrocyte glycoprotein （MOG）， myelin basic protein （MBP）， proteolipid protein （PLP）， inducible nitric oxide synthase （iNOS）， arginase-1 （Arg1）， CD86， CD206， and CD22， SHP-1， and p-Akt. Immunofluorescence was used to evaluate myelin-associated glycoprotein （MAG） intensity and the proportion of iNOS⁺/ionized calcium-binding adapter molecule 1 （Iba1）⁺ cells. ELISA was used to detect tumor necrosis factor-α （TNF-α）， interleukin （IL）-6， and IL-1β. ResultsCompared with the normal group， the model group exhibited markedly increased biting and aggressive behaviors and shortened attack latency （P<0.01）. MOG， MBP， and PLP protein levels and MAG fluorescence intensity were significantly reduced （P<0.05， P<0.01）. INOS and CD86 expression and TNF-α， IL-6， and IL-1β levels were significantly elevated （P<0.01）. CD22 and SHP-1 expression increased significantly （P<0.01）， whereas p-Akt expression decreased （P<0.01）. Compared with the model group， the medium- and high-dose HLJDT groups and the risperidone group showed markedly reduced biting and aggression （P<0.05， P<0.01） and prolonged attack latency （P<0.01）. MOG， MBP， and PLP levels and MAG fluorescence intensity were significantly increased （P<0.05， P<0.01）. INOS， CD86， TNF-α， IL-6， and IL-1β levels decreased significantly （P<0.05， P<0.01）. CD22 and SHP-1 expression decreased， while p-Akt expression increased significantly （P<0.05， P<0.01）. ConclusionHLJDT may modulate CD22/SHP-1/p-Akt signaling in the VMHvl， promote the shift of MG toward an anti-inflammatory and phagocytic phenotype， enhance myelin repair， and improve agitation-like behaviors in VAD mice.

Objective To establish the HPLC fingerprints for the different extracts from Coptidis Rhizoma，and investigate the spectrum-effect relationship between HPLC fingerprints and anti-Staphylococcus aureus activity in vitro to analyze the pharmacodynamic material basis. Methods Nine kinds of Coptidis Rhizoma extracts were prepared, and establish the HPLC fingerprints for them. The antibacterial rate of each extract was determined by the broth microdilution method with Staphylococcus aureus as the test bacteria. The grey relational analysis （GRA） method was used to analyze the correlation between the fingerprint data and the in vitro antibacterial test data. Results The HPLC fingerprints of nine kinds of Coptidis Rhizoma extracts were established, nine common characteristic fingerprint peaks were calibrated, and 5 peaks were identified by the reference substance comparison method. GRA analysis experiments showed that the correlation between nine peaks and antibacterial effect was 0.559 1~0.803 3; and the peak 3, peak 8 （palmatine hydrochloride）, peak 9 （berberine hydrochloride） were positively correlated with the inhibition of Staphylococcus aureus,while the peak 9 （berberine hydrochloride） had the strongest effect, and its correlation degree was 0.803 3. Conclusion The effective substance of antibacterial was preliminarily determined through the study of spectrum-effect relationship for Coptidis Rhizoma extracts,which may be the alkaloids, mostly containing hydrochloride, which provided a reference for further research on the pharmacodynamic material basis of Coptidis Rhizoma.

BackgroundNon-suicidal self-injury （NSSI） behavior among adolescents has become a global public health concern. Anxiety and depression are considered key factors influencing NSSI behavior， while social support may play a protective role in alleviating emotional and behavioral issues. However， existing research has primarily focused on the direct impact of individual factors on NSSI behavior， with insufficient exploration of the combined effects of anxiety， depression and social support. ObjectiveTo investigate the direct effect of anxiety on NSSI， the mediating role of depression and the moderating role of social support in relationship between anxiety and NSSI behavior， thus to provide references for the prevention and intervention of NSSI behavior among adolescents. MethodsIn February 2022， a total of 40 820 students in grades 7 to 12 across 10 middle schools in a district of Chengdu were selected as participants， and they were assessed using Generalized Anxiety Disorder Scale-7 item （GAD-7）， Patient's Health Questionnaire Depression Scale-9 item （PHQ-9）， Social Support Scale for Urban Students （SSSUS） and Adolescent Self-Harm Scale （ASHS）. Pearson correlation analysis was conducted to examine the correlations between scale scores among adolescents with NSSI behaviors. Mediation and moderation analyses were performed using Process 3.5 in SPSS， and the significance was tested with bootstrapping. The interaction was visualized by using simple slope analysis. ResultsAmong 34 534 （84.60%） valid respondents， 542 adolescents （1.57%） reported engaging in NSSI behavior. Significant differences in gender， GAD-7 scores， PHQ-9 scores， and SSSUS scores were observed between NSSI behavior group and non-NSSI group （χ²/t=62.889， 71.120， 94.365， -41.464， P<0.01）.Adolesents with NSSI showed positive correlations between GAD-7 scores and both ASHS and PHQ-9 scores （r=0.158， 0.166， P<0.01）. PHQ-9 scores were positively correlated with ASHS scores （r=0.364， P<0.01）， but negatively correlated with SSSUS scores （r=-0.290， P<0.01）. SSSUS scores were negatively correlated with ASHS scores （r=-0.247， P<0.01）. Depression partially mediated the relationship between anxiety and NSSI behavior， with an effect size of 0.544 （95% CI： 0.162~0.944）， accounting for 35.79% of the total effect. Social support moderated the relationship between depression and NSSI bahavior， with an effect value of -0.082 （95% CI： -0.135~-0.029）. ConclusionAnxiety not only directly influences NSSI bahavior among adolescents， also indirectly exacerbates it through depression， while social support mitigates the impact of depression on NSSI behavior. ［Funded by Youth Project of National Natural Science Foundation of China （number， 82401812）； Project of Health Commission of Sichuan Province （number， 24LCYJPT18）］

The cooccurrence of NPM1, FLT3-ITD, and DNMT3A mutations (i.e., triple mutation) is related to dismal prognosis in patients with acute myeloid leukemia (AML) receiving chemotherapy alone. In this multicenter retrospective cohort study, we aimed to identify whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut AML across four transplant centers in China. Fifty-three patients with triple-mutated AML receiving allo-HSCT in complete remission were enrolled. The 1.5-year probabilities of relapse, leukemia-free survival, and overall survival after allo-HSCT were 11.9%, 80.3%, and 81.8%, respectively. Multivariate analysis revealed that more than one course of induction chemotherapy and allo-HSCT beyond CR1 were associated with poor survival. To our knowledge, this work is the largest study to explore the up-to-date undefined role of allo-HSCT in patients with triple-mutated AML. Our real-world data suggest that allo-HSCT could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut in AML.

OBJECTIVE To investigate the mechanism of baicalin in alleviating the intestinal mucosal barrier injury in rats with intraperitoneal infection-induced sepsis through the vitamin D receptor(VDR)/nuclear factor E2-relat-ed factor 2(Nrf2)/haemoglobin oxygenase-1(HO-1)signalling pathway.METHODS Twenty-four SD rats were randomly divided into a sham-surgery group,a model group,an ulinastatin group and a baicalin group,with six rats in each group.Sepsis models were established via cecal ligation and puncture(CLP)in rats in each groups ex-cept for the sham surgery group.Six hours after modeling,the sham-surgery and the model groups received intra-peritoneal saline,while the ulinastatin and baicalin groups were administered ulinastatin at 20,000 U/kg and ba-icalin at 100 mg/kg,respectively,via intraperitoneal injection once daily for 5 consecutive days.The histopatho-logical changes in the ileum tissue of rats in each group were observed,and the levels of oxidative stress,inflam-matory factors,and the expression of related mRNA and proteins in the VDR/Nrf2/HO-1 signalling pathway were compared.RESULTS Compared with the sham-surgery group,the model group showed disordered villus ar-rangement,severe intestinal mucosal atrophy and inflammatory cell infiltration,with necrotic epithelial cell shed-ding.Additionally,in the model group,the total antioxidant capacity(T-AOC),superoxide dismutase(SOD),and glutathione peroxidase(GSH-PX)levels reduced,while the levels of tumor necrosis factor-α(TNF-α),inter-leukin(IL)-6,and IL-1βsignificantly increased,and the expression of VDR mRNA,Nrf2 mRNA,HO-1 mR-NA,and VDR,Nrf2,and HO-1 proteins were downregulated(P<0.05).Compared with the model group,the ulinastatin group and the baicalin group showed that villus arrangement,intestinal mucosal atrophy and inflamma-tory cell infiltration got improved,the levels of T-AOC,SOD,and GSH-PX elevated,the levels of TNF-α,IL-6,and IL-1βdecreased,and expressions of VDR mRNA,Nrf2 mRNA,HO-1 mRNA,and VDR,Nrf2,and HO-1 proteins were upregulated.Moreover,all indicators in the baicalin group were superior to those in the ulinastatin group(P<0.05).CONCLUSION Baicalin can inhibit the expression of inflammatory factors and regulate the bal-ance of oxidative stress in vivo by up-regulating the VDR/Nrf2/HO-1 signaling pathway,thereby alleviate the in-testinal mucosal barrier dysfunction caused by intraperitoneal infection-induced sepsis.

Objective To explore the impact of nursing intervention based on the information-motivation-behavioral skill(IMB)model on the acceptance of disability in stroke patients.Methods A total of 92 patients with first-onset stroke who were hospitalized at the Affiliated Hospital of Hangzhou Normal University from July 2022 to December 2023 were selected and divided into experimental group(47 cases)and control group(45 cases)according to the random number table method.The control group received routine care,while the experimental group received nursing intervention based on the IMB model in addition to routine care.The acceptance of disability and depression levels of two groups were compared.Results After the intervention,the acceptance of disability in experimental group was significantly higher than that in control group and increased over time(P＜0.05).The degree of depression in experimental group was significantly lower than that in control group and decreased over time(P＜0.05).Conclusion Nursing intervention based on the IMB model can enhance the acceptance of disability among stroke patients,reduce the degree of depression,and improve disease prognosis,demonstrating good clinical practical value.

The paper presents a case of 69-year-old male with marginal zone lymphoma (MZL) manifesting as acute kidney injury (AKI) requiring emergency hemodialysis. The patient presented with fever, fatigue and rapidly progressive renal dysfunction, and serum creatinine was 1 105 μmol/L. Emergency central venous catheterization and hemodialysis were performed. Serum immunofixation electrophoresis revealed monoclonal IgM and λ light chain positivity. Autoantibody testing showed positivity for both anti-SSA and anti-SSB antibodies. Renal biopsy demonstrated interstitial infiltration by atypical B lymphocytes with λ light chain restriction. The diagnosis of MZL was confirmed by bone marrow biopsy. Following hemodialysis and chemotherapy with bendamustine plus rituximab, renal function significantly improved and remained stable during follow-up. This case highlights that AKI may serve as the initial manifestation of lymphoma, underscoring the importance of considering hematologic malignancies in the differential diagnosis of unexplained renal failure.
