To analyze the disease burden of acute lymphoid leukemia(ALL) and its changing trends in China and globally from 1990 to 2021, aiming to provide a theoretical basis for disease prevention, treatment, and policy formulation.

In recent years, it has become a new direction in the field of neuroscience to explore the mode characteristics, functional significance and interaction mechanism of resting spontaneous electroencephalography (EEG) and task-evoked EEG. This paper introduced the basic characteristics of spontaneous EEG and task-evoked EEG, and summarized the core role of spontaneous EEG in shaping the adaptability of the nervous system. It focused on how the spontaneous EEG interacted with the task-evoked EEG in the process of task processing, and emphasized that the spontaneous EEG could significantly affect the performance of tasks such as perception, cognition and movement by regulating neural activities and predicting external stimuli. These studies provide an important theoretical basis for in-depth understanding of the principle and mechanism of brain information processing in resting and task states, and point out the direction for further exploring the complex relationship between them in the future.

Objective To systematically evaluate the risk prediction model for central venous catheter-related bloodstream infections and provide references for clinical practice.Methods Databases such as CNKI,Wanfang,CBM,VIP,PubMed,Web of Science,Cochrane Library,etc.were retrieved.The search period is from database establishment to June 2,2023.There are 2 researchers who independently screened and extracted the literature,and evaluated the quality of the literature using bias assessment tools of predictive model risk.Results A total of 9 articles were included,including 9 risk prediction models for catheter-related bloodstream infections.The total sample size was 80～11 901 cases;the number of outcome events was 19～403 cases;the C index of the included model was 0.81～0.93.The area under the curve of the subjects ranged from 0.73～0.90.The predictors that appear more frequently in the model mainly included the history of diabetes,albumin value,the number of days of catheterization,the location of catheterization.The evaluation results of the bias assessment tool of predictive model risk for research show that the overall applicability of the included risk prediction models is good,but the bias risk is high.The reasons are related to the improper source of research sample data,inappropriate processing of continuous variable methods,failure to process missing data,insufficient model performance evaluation,and non-standard evaluation indicators.Conclusion There are still some shortcomings in the risk prediction model for central venous catheter-related bloodstream infections.In the future,the quality of related model research should be further improved,especially in terms of predictive factor analysis,model evaluation indicators,etc.,which should be further standardized.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

Objective To explore the value of 11C-methionine(MET)PET/CT radiomics model for evaluating isocitrate dehydrogenase1(IDH1)status of glioblastoma.Methods Data of 157 patients with glioblastoma who underwent 11C-MET PET/CT examination,including 68 cases of IDH1 mutation and 89 cases of IDH1 wild-type were retrospectively analyzed.The patients were divided into training set(n=125)and validation set(n=32)at the ratio of 8:2.Based on PET/CT images,lesions ROI were delineated and radiomics features were extracted and screened to establish radiomics models with logistic regression(LR),support vector machine(SVM)and decision trees(DT),respectively.Meanwhile,the nomogram based on patients'age and radiomics features was drawn.The efficacy of radiomics models and clinical-radiomics nomogram for evaluating IDH1 status were comparatively observed.Results The area under the curve(AUC)of DT radiomics model for evaluating IDH1 status of glioblastoma in training set was 0.910,higher than that of LR(0.697)and SVM(0.698)models(both P＜0.05).In validation set,the AUC of DT model for evaluating IDH1 status of glioblastoma was 0.805,which was higher than that of LR model(0.740)and clinical-radiomics nomogram(0.704)(both P＜0.05).Conclusion 11C-MET PET/CT radiomics model based on DT was helpful for evaluating IDH1 status of glioblastoma.

Objective To explore the regulatory and functional mechanism of angiopoietin-like 4(ANGPTL4)expression in gastric epithelial cells infected with Helicobacter pylori(H.pylori).Methods H.pylori-positive gastric specimens from Department of Gastroenterology of second Affiliated Hospital of Army Medical University in November 2021 and the gastric tissues of H.pylori-infected mice were collected,and the expression locations of ANGPTL4 in these gastric tissues were detected by immunofluorescence assay.After gastric epithelial cells and gastric organoids were infected with H.pylori,the expression of ANGPTL4 was detected by real-time PCR and Western blotting.The regulatory mechanism of H.pylori-induced ANGPTL4 expression was investigated by cellular models above.Recombinant ANGPTL4 was used to stimulate gastric epithelial cells to investigate the effect of ANGPTL4 on the claudin 1(CLDN1)expression.Results H.pylori infection significantly increased the expression of ANGPTL4 in gastric epithelial cells in a CagA-dependent,bacterial concentration-dependent and infection time-dependent manner(P＜0.05).Compared to uninfected cells and CagA knockout(ΔcagA)H.pylori-induced ones,the ANGPTL4 expression was significantly increased in WT H.pylori-infected human and mouse gastric organoid(P＜0.05).Blocking NF-κB signaling pathway significantly inhibited the enhanced ANGPTL4 expression in H.pylori-infected gastric epithelial cells(P＜0.05).Recombinant ANGPTL4 activated ERK signaling pathway to down-regulate the CLDN1 expression in gastric epithelial cells(P＜0.05).Conclusion H.pylori activates NF-κB signaling pathway to up-regulate ANGPTL4 expression in gastric epithelial cells in a CagA-dependent manner,and ANGPTL4 activates ERK signaling pathway to down-regulate the CLDN1 expression in gastric epithelial cells,which may contributes to the development of gastric diseases induced by H.pylori infection.

Objective To evaluate the effectiveness,safety and economy of the clinical application of levetiracetam(LEV)concentrated solution for injection generic drug and the original drug in the national centralized volume-based procurement.Methods The information of inpatients using original LEV concentrated solution for injection in the Xuanwu Hospital of Capital Medical University(original drug group)and inpatients using generic LEV concentrated solution for injection in the First Affiliated Hospital of Wannan Medical College(generic drug group)was retrospectively analyzed after the implementation of the procurement policy(from November 2021 to March 2022).To compare the effectiveness,safety and economy of the two in the prevention and treatment of epilepsy.Results In the original drug group and the generic drug group,18 and 17 patients were enrolled in the treatment of epilepsy respectively,the effective rates were 50.00％and 58.82％,the incidence of adverse reactions were both 0％,and the median daily cost was 255.00(255.00,510.00)yuan and 131.78(131.78,131.78)yuan.After propensity score matching,both the original drug group and the generic drug group had 76 patients each received preventive medication,the effective rates were 97.37％and 100％(P＞0.05),and the incidence of adverse reactions were both 0％.The median daily fee for the original the generic drug group was 170.00(170.00,170.00)yuan and 131.78(131.78,131.78)yuan,there were significant difference(P＜0.01).Conclusion The clinical effect of generic and original LEV concentrated solution for injection in preventing epilepsy is basically the same,the clinical safety are equivalent,the generic has better economy than the original.The effective rate of the treatment of epilepsy is similar,while the sample size needs to be further expanded to verify the results.
