Objective To investigate the relationship between serum trimethylamine oxide(TMAO),endo-thelial cell specific molecule 1(Endocan)and cardiac function and pregnancy outcome in patients with hyper-tensive disorders of pregnancy(HDP).Methods A total of 182 patients with HDP admitted to Handan Ma-ternal and Child Health Hospital from January 2021 to June 2023(HDP group)and 98 healthy pregnant women admitted to this hospital during the same period(control group)were selected as research subjects.Serum TMAO,Endocan and left ventricular cardiac function indexes[left ventricular ejection fraction(LVEF),left ventricular end-diastolic volume(LVEDV)and left ventricular end-systolic volume(LVESV)]were compared between the two groups.According to pregnancy outcome,HDP patients were divided into poor outcome group(78 cases)and good outcome group(104 cases).Spearman correlation analysis was used to analyze the correlation between serum TMAO and Endocan and cardiac function indexes in HDP patients,and multi-factor Logistic regression was used to analyze the influencing factors of adverse pregnancy outcomes in HDP patients.The predictive value of serum TMAO and Endocan for adverse pregnancy outcomes in HDP patients was analyzed by receiver operating characteristic(ROC)curve.Results Compared with control group,serum TMAO,Endocan,LVEDV and LVESV were increased in HDP group,and LVEF was decreased(P＜0.05).Serum TMAO and Endocan in HDP patients were negatively correlated with LVEF(P＜0.05),and positively correlated with LVEDV and LVESV(P＜0.05).The incidence of adverse pregnancy outcomes in 182 HDP patients was 42.86％(78/182).Preeclampsia(PE),severe preeclampsia(SPE),24 h urine protein increase,LVEDV increase,LVESV increase,TMAO increase,Endocan increase were independent risk factors for adverse pregnancy outcomes in HDP patients,and LVEF increase was protective factor(P＜0.05).The area under the curve of serum TMAO combined with Endocan in predicting adverse pregnancy outcomes in HDP patients was 0.880,which was greater than 0.793 and 0.788 predicted by serum TMAO and Endocan a-lone.Conclusion The increase of serum TMAO and Endocan levels in HDP patients are relate to the decrease of cardiac function and adverse pregnancy outcomes,and the combined detection of the two has high predictive value for adverse pregnancy outcomes in HDP patients.

Objective To explore the relationship between serum pregnancy-specific protein 1(PSG1),stress-induced protein 2(Sestrin 2),growth arrest-specific protein 6(Gas6)and uterine artery blood flow pa-rameters and fetal growth restriction(FGR)in patients with gestational hypertension(GH).Methods A to-tal of 485 GH patients admitted to Handan Maternal and Child Health Hospital from January 2020 to October 2023 were selected as the research objects and divided into the occurrence group(81 cases)and the non-occur-rence group according to whether FGR occurred.The correlations between serum PSG1,Sestrin 2,Gas6 and uterine artery blood flow parameters[pulse index(PI),resistance index(RI),ratio of peak systolic velocity to end diastolic velocity(S/D)]was analysed,as well as the related influencing factors of FGR in GH patients.In addition,a Nomogram model based on the influencing factors was constructed to analyze the predictive value.Results The serum PSG1 level in occurrence group was significantly lower than that in non-occurrence group,and the serum Sestrin 2,Gas6 levels and PI,RI,S/D values were significantly higher than those in non-occurrence group(P＜0.05).Pearson correlation results showed that serum PSG1 was negatively correlated with the uterine artery blood flow parameters PI,RI,and S/D,and the levels of serum Sestrin 2 and Gas6 were positively correlated with the uterine artery blood flow parameters PI,RI,and S/D(P＜0.05).Gestational di-abetes mellitus,umbilical cord abnormalities,high Sestrin 2,high Gas6,high PI,high RI,and high S/D were independent risk factors for the occurrence of FGR in GH patients(P＜0.05),and increased PSG1 level was protective factor for the occurrence of FGR in GH patients(P＜0.05).Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC)of the Nomogram prediction model con-structed based on the influencing factors for predicting the occurrence of FGR in GH patients was 0.982,and the sensitivity and specificity were 0.943 and 0.938,respectively.The internal verification of the Bootstrap method shows that the Bias-corrected prediction curve basically coincides with the Ideal line,and the consis-tency index(C-index)was 0.964,indicating that the model was relatively stable.The decision curve shows that the threshold probability of this model was 0.01-1.00 and the net return rate was above 0.Conclusion Ser-um PSG1,Sestrin 2 and Gas6 in GH patients are closely related to uterine artery blood flow parameters and FGR,and the three are the influencing factors for the occurrence of FGR in GH patients.The constructed No-mogram model has a good predictive efficacy for FGR.

Objective:To investigate the clinicopathological and molecular genetic characteristics of diffuse gliomas with the features of polymorphous low-grade neuroepithelial tumor of the young (PLNTY) and their prognostic values.Methods:A retrospective analysis was performed on 14 cases of diffuse gliomas with PLNTY features diagnosed at the First Affiliated Hospital of Fujian Medical University, Fuzhou, China from June 2020 to August 2024. Their clinicopathological characteristics were examined, and their molecular genetic and epigenetic features were assessed using next-generation sequencing (NGS) and methylation analysis. Factors influencing prognosis were also analyzed.Results:Among the 14 patients, there were 8 males and 6 females, aged 3-62 years, median 29 (9, 50) years. All cases were initially diagnosed as low-grade diffuse gliomas histologically but exhibited the histological and immunohistochemical features of PLNTY. At the molecular level, all cases showed molecular abnormalities involving the mitogen-activated protein kinase pathway, including 5 cases with FGFR3-TACC3 (F3T3) fusion, 3 cases with FGFR2 fusion, 5 cases with BRAF V600E mutation, and 1 case with FGFR1 mutation. Among them, TERT promoter mutations were frequently observed in tumors with F3T3 fusion (5/5), while NCOR2 in-frame insertion mutations were prominent in tumors with non-F3T3 fusions. Clinical follow-up showed recurrence in 3 cases, all of which had F3T3 fusion and concurrent TERT promoter mutations. Prognostic analysis confirmed that F3T3 fusion with concurrent TERT promoter mutation was associated with poor prognosis.Conclusions:Diffuse gliomas with PLNTY features exhibit heterogeneity in clinicopathology and molecular genetics, with FGFR3/FGFR2 fusions and BRAF/FGFR1 mutations as the most common molecular alteration. They often have concurrent F3T3 fusion and TERT promoter mutations, which are related to poor prognosis. The possibility of molecular glioblastoma should be considered for these tumors. It is thus recommended to perform genetic testing on diffuse gliomas with PLNTY features in order to facilitate integrated diagnosis and provide molecular evidence for accurate evaluation of prognoses.

Pathological interaction between CD4 + T cells and B cells is one of the important mechanisms of systemic autoimmune diseases. Follicular helper T cells (Tfh) and peripheral helper T cells (Tph) are key cells for assisting B cells. Tph cell is a newly discovered helper T cell subset, and their phenotype is PD-1 highCXCR5 -CD4 +. Tph cell and Tfh cell have certain differences in phenotype, function, and site of action. It interacts with B cells, promoting the differentiation of B cells into plasma cells and the production of autoantibodies, as well as promoting the formation of ELS to maintain local inflammation and antibody responses. Tph cells have recently been reported in various autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, Sjogren′s syndrome, and IgG4-related diseases. This review summarizes the progress in peripheral immune response of Tph cells in different systemic autoimmune diseases, aiming to explore the new mechanism of autoantibody production and help to develop new diagnostic and therapeutic targets in the future.

Objective:To investigate the clinical manifestations, pathological features, and genetic variant characteristics of children with glycogen storage disease type Ⅸa (GSD Ⅸa).Methods:A retrospective case series analysis was conducted to collected and analyzed the medical history, biochemical markers, liver ultrasound results, liver histopathological findings, genotypes, treatment regimens, and follow-up data of 4 pediatric patients diagnosed with GSD IXa in the Department of Infectious Diseases at Xiamen Children′s Hospital from January 2018 to May 2024. All patients were confirmed by genetic testing.Results:All 4 pediatric patients diagnosed with GSD Ⅸa were male. The ages of onset were 8 months, 2 years, 3 years and 3 months, 1 year and 5 months, respectively, with initial presentations including chronic diarrhea (Case 1), incidentally detected transaminase elevation during routine examinations (Cases 2 and 3), and delayed motor development (Case 4). Diagnosis was confirmed at ages 10 months, 3 years, 3 years 4 months and 1 year 6 months, respectively.At diagnosis, anthropometric parameters and biochemical profiles revealed:Height: 68 cm (< P3), 96 cm ( P25-50), 94 cm ( P3-10), and 94 cm ( P3-10).Weight: 7 kg (< P3), 17 kg ( P90-97), 14.4 kg ( P25-50), and 10.5 kg ( P25-50).Alanine aminotransferase: 299, 500, 271, and 313 U/L (reference range 0-40 U/L).Aspartate aminotransferase: 285, 543, 337 and 357 U/L (reference range 0-40 U/L).Fasting glucose: 2.80, 3.67, 2.98, and 3.66 mmol/L (reference range 3.90-6.10 mmol/L).Lactate: 4.3, 2.1, 1.3, and 2.6 mmol/L (reference range 0.5-2.2 mmol/L).Triglycerides: 5.22, 1.38, 1.32, and 1.88 mmol/L (reference range 0.56-1.70 mmol/L).Case 1 exhibited poor adherence to uncooked cornstarch therapy during initial treatment, with no significant improvement in biochemical parameters. Follow-up imaging at age 4 revealed hepatic adenoma. Subsequent improvement in therapeutic compliance led to biochemical normalization, reduced hepatic adenoma size, and growth parameters of 113 cm ( P10-25) and 26 kg ( P90-97) at 6 years 2 months. Cases 2-4 demonstrated biochemical improvement with regular uncooked cornstarch therapy and no evidence of hepatic adenoma.Liver histopathology in Cases 1-3 confirmed glycogen accumulation consistent with GSD, without cirrhotic changes. Genetic analysis identified PHKA2 variations in all cases: 2 missense variants, 1 frameshift variant and 1 nonsense variant. The c.2839dup and c.3267G>A variants represent novel pathogenic mutations. Conclusions:GSD Ⅸa in pediatric patients is predominantly characterized by hepatomegaly, hepatic dysfunction, and hypoglycemia. While uncooked cornstarch therapy typically yields favorable prognoses, a subset of patients may develop hepatic adenomas. Notably, children with hepatic adenoma exhibited younger age of onset, significant growth retardation, and more severe metabolic disturbances, suggesting that hepatic adenoma development may be closely linked to the severity of metabolic dysregulation.

Objective To conduct a scope review of the factors that influence the occupational grief in nurses in order to provide a reference for future interventional research on the occupational grief in nurses.Methods Based on the framework of scope review report,a systematic search was conducted across multiple databases,including China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP,SinoMed,Cochrane Library,Embase,Scopus,PubMed,Web of Science and EBSCO,for relevant literature published from the inception of databases to 8th April,2025(updated after revision).The retrieved literature was screened,evaluated,analysed and summarised.Results A total of 12 articles were included in the study.The factors that influenced occupational grief of nurses were identified in seven dimensions:demographics,personal experience,psychological state,education and training,patient-related factors,career environment and supporting factors.The identified dimensions comprised a total of 27 influencing factors.Conclusion Occupational grief among nurses is common.Grief is influenced by multiple factors,including demographics,personal experience,psychological state,educational background,patient-related factors,career environment and supporting systems.Nurses and nursing administrators should attach great importance to occupational grief,identify the adverse emotions early,and provide effective intervention strategies in a timely manner.

In modern society,the diversity of risk causes,the complexity of risk trans-mission paths and the cascading effect of risk consequences make the uncertainty of the run risk of medical and health system increase sharply,and risk governance has become a rising topic in the academic circle.However,the traditional risk management system is riddled with difficulties,which has been difficult to meet the needs of modern governance,and resilient governance provides a new perspective for improving the governance capacity of the medical and health system run risk,and promotes risk management to"turn brittle into tough".How to empower the technical advantages of resilience governance to manage the run risk of the healthcare system,break the obstruction of the traditional governance mechanism,and explore its internal mechanism and driving mechanism are the key issues to realize the innovation of resilient governance and the modernization of governance capacity.
