Objective: To evaluate the intervention effect of school based salt reduction health education, so as to provide a scientific basis for constructing a more effective and sustainable salt reduction intervention model for children. Methods: According to a randomized controlled trial design, in June 2022, probability proportional to size sampling was used to select 501 second grade students (248 in the control group and 253 in the intervention group) from 10 primary schools in Zhenjiang (intervention group) and 10 primary schools in Yangzhou (control group), Jiangsu Province. An one year school based salt reduction health education intervention was implemented. This included 20 online and 8 offline health education sessions, monitoring of salt consumption in the canteen, and the establishment of a salt reduction environment on campus. The control group received no additional salt reduction interventions. A questionnaire survey and 24 hour urinary sodium test were conducted before and after the intervention. The difference in differences method was used to evaluate the intervention effect. Results: After the intervention, the intervention group showed significant net intervention effects in knowledge aspects, including knowing that primary school students consume less salt than adults ( OR=3.55,95%CI =1.69-7.47), daily salt intake of primary school students ( OR=6.64,95%CI =3.71-11.87), long term high salt intake leading to hypertension ( OR=6.83,95%CI =3.93-11.91), low salt intake not causing hair graying ( OR= 1.66 ,95%CI =1.00-2.75), salt content in food labels ( OR=4.56,95%CI =2.63-7.91), and common high salt foods ( OR=3.39,95%CI =1.87-6.14) (all P <0.05). In terms of attitude, the net intervention effect for having a positive attitude toward using less salt in home cooking was significantly increased ( OR=1.88,95%CI =1.13-3.12, P <0.05). There were no statistically significant net intervention effects for salt reduction related behaviors (all P >0.05). There was no statistically significant difference in the changes of 24 hour urinary sodium between the intervention group and the control group before and after intervention ( P >0.05). Conclusions School based salt reduction health education effectively improves students salt reduction knowledge and attitudes but has a limited effect on behavior change. The home-school collaboration should be strengthened, and the dietary environment should be optimized simultaneously.

Objective To explore the impact of irregular shape of head CT hematomas on postoperative re-bleeding and prognosis of patients with spontaneous intracerebral hemorrhage(ICH)who undergo craniotomy for hematoma evacuation.Methods We retrospectively enrolled consecutive patients with ICH who underwent craniotomy for hematoma evacuation in the Department of Neurosurgery of the Second People's Hospital of Guiyang Affiliated to Guizhou Medical University from January 2019 to June 2024.Baseline and clinical data were collected form the patients,including age,gender,smoking history,drinking history,hypertension,diabetes,history of anticoagulant use,admission systolic and diastolic blood pressure,admission National Institutes of Health stroke scale(NIHSS)score,Glasgow coma scale(GCS)score,time from onset to the first head CT,neutrophil-to-lymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).Admission head CT scans were used to assess hematoma shape(regular or irregular),hematoma location(basal ganglia,lobar,multifocal),hematoma volume,perihematomal edema volume,the presence of midline shift,and intraventricular extension.Volume of the hematoma was assessed 2 days after surgery.Postoperative re-bleeding is defined as an increase in the volume of the hematoma by 12.5 ml compared to the previous postoperative CT scan within 2 weeks after surgery,or the reappearance of high-density areas in the focal area of the head CT scan during follow-up after complete hematoma clearance.Conduct patients follow-ups via telephone at 6 months postoperatively to assess their modified Rankin scale(mRS)scores.The sliding dichotomy method was applied to define prognosis based on the patients' baseline characteristics and disease severity.The prognostic score was calculated using formula:10 × admission GCS score-age-0.64 × admission hematoma volume.A prognostic score＞27.672 was considered potentially favorable,while a score ≤ 27.672 was considered potentially unfavorable.For patients with a potentially favorable prognosis,an mRS score of 0-2 was defined as a good outcome,and a score of 3-6 as a poor outcome.For those with a potentially unfavorable prognosis,an mRS score of 0-3 was defined as a good outcome,and a score of 4-6 as a poor outcome.In the comparison of baseline and clinical data between patients with regular and irregular hematoma shapes,factors with P＜0.05 were included in propensity score matching(PSM)to adjust for confounding variables.A 1∶1 matching was performed using the nearest neighbor method with a caliper value set to 0.25.Variables with statistically significant differences between groups after PSM matching were included in the multivariate Logistic regression analysis to identify influencing factors for postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy hematoma evacuation.The predictive value of irregular hematoma shape for postoperative rebleeding and poor prognosis in ICH patients was analyzed using receiver operating characteristic(ROC)curve analysis.Results(1)A total of 440 ICH patients were enrolled,including 342 males and 98 females,aged from 20 to 84 years with a mean age of(56±12)years.Statistically significant differences were observed in baseline and clinical data between patients with regular and irregular hematoma shapes before PSM,including age,admission GCS score,NIHSS score,NLR,proportion of patients with hematoma rupture into ventricles,preoperative hematoma volume,proportion of patients with midline shift,preoperative volume of hematoma surrounding edema,proportion of patients with hematoma located in multiple sites,and postoperative 2-day hematoma volume(all P＜0.05).After propensity score matching of these factors,298 ICH patients were included in the statistical analysis,comprising 228 males and 70 females,with an age range of 20 to 84 years and a mean age of(57±12)years.Following PSM,no statistically significant differences were observed in the baseline and clinical characteristics between patients with irregular and regular hematoma shapes(all P＞0.05).(2)After propensity score matching,28 patients experienced postoperative re-bleeding while 270 did not.Significant differences were observed between the two groups in the following factors:proportion of patients with a history of anticoagulant use,admission PLR,NLR,irregular hematoma shape,and hematoma volume at 2 days after operation(all P＜0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P＞0.05).Using postoperative re-bleeding as the dependent variable and incorporating factors with P＜0.05 from the univariate analysis as independent variables,multivariate Logistic regression analysis identified irregular hematoma shape(OR,2.821,95％CI 1.142-6.968,P=0.025)and larger hematoma volume at 2 days post-operation(OR,1.062,95％CI 1.026-1.099,P＜0.01)as independent risk factors for re-bleeding following intracranial hematoma evacuation in ICH patients.ROC curve analysis demonstrated that irregular hematoma shape predicted postoperative re-bleeding with an area under the curve(AUC)of 0.62,showing a sensitivity of 71.4％and a specificity of 52.2％.(3)After propensity score matching,174 patients had poor prognosis while 124 had good prognosis.Significant intergroup differences were observed in age,admission GCS score,NIHSS score,irregular hematoma shape,proportion of patients with hematomas located in the basal ganglia and cerebral lobes,and hematoma volume at 2 days post-operation(all P＜0.05).No statistically significant differences were found in the remaining baseline and clinical characteristics(all P＞0.05).Using poor prognosis as the dependent variable and incorporating factors with P＜0.05 from univariate analysis as independent variables,multivariate Logistic regression analysis revealed that advanced age(OR,1.039,95％CI 1.015-1.064,P=0.002),high admission NIHSS score(OR,1.068,95％CI 1.025-1.113,P=0.002),irregular hematoma shape(OR,2.675,95％CI 1.582-4.524,P＜0.01),and larger hematoma volume at 2 days post-operation(OR,1.033,95％CI 1.002-1.064,P=0.038)were independent risk factors for poor prognosis.Conversely,lobar hematoma location(OR,0.192,95％CI 0.073-0.504,P＜0.01)was identified as a protective factor.ROC curve analysis showed that irregular hematoma shape predicted poor prognosis after intracranial hematoma evacuation with an AUC of 0.61,demonstrating a sensitivity of 59.2％and specificity of 62.9％.Conclusion Irregular hematoma shape on head CT is an independent risk factor for both postoperative re-bleeding and poor prognosis in ICH patients undergoing craniotomy for hematoma evacuation.

Objective:To investigate the correlation between remnant cholesterol/high-density lipoprotein cholesterol ratio (RC/HDL-C) and metabolic dysfunction-associated fatty liver disease (MAFLD) in health check-up population.Methods:It was a cross-sectional study. A total of 5 299 subjects who received physical examination in the Health Management Center of Renmin Hospital of Wuhan University from January to December in 2023 and met the admission criteria were selected as the research subjects. The subjects were examined by demography, anthropometry, laboratory tests and liver instantaneous elastography. The Chi-square test, t-test, one-way analysis of variance, Mann-Whitney U test and Kruskal-Wallis H test were used to compare the indexes between the subjects with and without MAFLD. The subjects were divided into 4 groups (Q1-Q4 groups) according to the RC/HDL-C ratio quartiles by quartile method, and the indexes in each group were compared. The receiver operating characteristic (ROC) curves were drawn using MedCalc software and compared to assess the diagnostic efficacy of the RC/HDL-C ratio for MAFLD. Results:With the increase of RC/HDL-C ratio, the detection rate of MAFLD (12.56% vs 43.48%), male proportion (55.68% vs 85.60%), total cholesterol (TC) [(4.63±0.82) vs (5.10±1.06) mmol/L], triglyceride (TG) [0.90(0.71, 1.15) vs 2.58(1.96, 3.50) mmol/L], alanine aminotransferase (ALT) [17.00(13.00, 24.00) vs 26.00(19.00, 38.00) U/L], aspartate aminotransferase (AST) [20.00(17.00, 24.00) vs 23.00(19.00, 29.00) U/L], and controlled attenuation parameter (CAP) [(239.32±40.52) vs (274.60±44.98) dB/m] increased gradually, while high-density lipoprotein cholesterol (HDL-C) [1.40(1.20, 1.64) vs 0.93(0.84, 1.04) μmol/L] decreased gradually (all P<0.05). ROC curves showed that the AUC value of RC/HDL-C ratio was significantly higher in identifying MAFLD when compared with TC, HDL-C, LDL-C, non-HDL-C and RC (AUC=0.676, P<0.05). Conclusions:The RC/HDL-C ratio is positively correlated with the risk of morbidity of MAFLD in health check-up population.

Objective:To investigated the safety and efficacy of donor-derived CD19+ or sequential CD19+ CD22+ chimeric antigen receptor T-cell (CAR-T) therapy in patients with B-cell acute lymphoblastic leukemia (B-ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The data of 22 patients with B-ALL who relapsed after allo-HSCT and who underwent donor-derived CAR-T therapy at the Zhujiang Hospital of Southern Medical University and the 920th Hospital of Joint Logistics Support Force of the People’s Liberation Army of China from September 2015 to December 2022 were retrospectively analyzed. The primary endpoint was overall survival (OS), and the secondary endpoints were event-free survival (EFS), complete remission (CR) rate, and Grade 3-4 adverse events.Results:A total of 81.82% ( n=18) of the 22 patients achieved minimal residual disease-negative CR after CAR-T infusion. The median follow-up time was 1037 (95% CI 546–1509) days, and the median OS and EFS were 287 (95% CI 132-441) days and 212 (95% CI 120-303) days, respectively. The 6-month OS and EFS rates were 67.90% (95% CI 48.30%-84.50%) and 58.70% (95% CI 37.92%-79.48%), respectively, and the 1-year OS and EFS rates were 41.10% (95% CI 19.15%-63.05%) and 34.30% (95% CI 13.92%-54.68%), respectively. Grade 1-2 cytokine release syndrome occurred in 36.36% ( n=8) of the patients, and grade 3-4 occurred in 13.64% of the patients ( n=3). Grade 2 and 4 graft-versus-host disease occurred in two patients. Conclusion:Donor-derived CAR-T therapy is safe and effective in patients with relapsed B-ALL after allo-HSCT.

Objective:To analyze the differentially expressed genes (DEGs) in visceral adipose tissue of patients with type 2 diabetes mellitus (T2DM) based on bioinformatics.Methods:The microarray dataset GSE78721 was downloaded from the Gene Expression Omnibus (GEO) database, including visceral fat samples data from 19 T2DM patients and 16 non-diabetic subjects. The analysis of transcriptomic profiling results from tissue samples was conducted, and a comparison between different groups of samples based on gender was performed. The online Xintao Academic Database was utilized for the analysis, employing the "limma" package in R language to filter DEGs. Subsequently, the DEGs were visualized, and Gene Ontology (GO) functional annotation along with Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were carried out and visualized. Based on the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database, a protein-protein interaction network (PPI) of DEGs was constructed and key differentially expressed genes were identified and visualized using Cytoscape software.Results:Analysis of visceral adipose tissue gene expression profiles revealed 168 DEGs (|log 2FC|≥1, P<0.05). In females, 42 mRNAs were up-regulated, 3 were down-regulated; in males, 105 were up-regulated, 37 were down-regulated, 19 genes were shared by the two groups. GO analysis linked DEGs to insulin-like growth factor receptor signaling and regulation, nutrient response, and leukocyte migration. KEGG analysis implicated extracellular matrix receptor interactions and leukocyte transendothelial migration. The PPI network unveiled 10 key genes, including COL1A1, COL1A2, TGFB3, PCOLCE, TIMP1, COL6A2, COMP, COL14A1, VCAM1 and THY1. Conclusion:Bioinformatics technology can effectively analyze and screen DEGs in visceral adipose tissue of T2DM patients, providing useful clues for further exploring its molecular mechanism and finding therapeutic targets.

Objective To investigate the effect of malignant cerebellar hemorrhage on 3-month prognosis of small spontaneous cerebellar hemorrhage.Methods Clinical data of 380 consecutive patients with spontaneous cerebellar hemorrhage admitted in Emergency Department of the Affil-iated Hospital of Guizhou Medical University,Neurosurgery Department of Jinyang Hospital Af-filiated to Guizhou Medical University,and Neurosurgery Department of the Second Affiliated Hospital of Guizhou Medical University from April 2014 to March 2023 were collected and retro-spectively analyzed,and finally,70 patients who met the requirements of small amount of sponta-neous cerebellar hemorrhage were enrolled in this study.They were assigned into benign cerebel-lar hemorrhage group(43 cases)and malignant cerebellar hemorrhage group(27 cases).Accord-ing to their clinical outcomes in 3 months after onset,they were divided into a good prognosis group(51 cases)and a poor prognosis group(19 cases).General clinical data,imaging data,com-plications,inflammatory indicators and prognosis were collected.After collinear diagnosis was used to exclude factors with collinear influence,the independent correlation between good progno-sis and poor prognosis was analyzed by binary logistic regression model.Finally,ROC curve was plotted to analyze the significant data.Results The maximum diameter of hematoma was signifi-cantly larger in the malignant cerebellar hemorrhage group than the benign group(P=0.021).The patients of the poor prognosis group had larger proportion of malignant cerebellar hemor-rhage,and higher neutrophil percentage,WBC count and NLR than those of the good prognosis group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that malignant cere-bellar hemorrhage was an independent predictor of poor prognosis in 3 months(OR=6.218,95％CI:1.140-17.623,P=0.013).The sensitivity,specificity,positive predictive value,negative pre-dictive value and Youden index of malignant cerebellar hemorrhage in predicting the 3-month prognosis of patients were 63.2％,70.6％,44.4％,83.7％and 0.338,respectively,and the AUC value was 0.669.Conclusion Malignant cerebellar hemorrhage is an independent predictor of 3-month prognosis in patients with small spontaneous cerebellar hemorrhage.The patients with malignant cerebellar hemorrhage have poor prognosis than those with benign cerebellar hemorrhage.
