Objective:To analyze the pathogen distribution and prognostic risk factors of catheter-related bloodstream infection (CRBSI) in patients with maintenance hemodialysis (MHD) during non-hospitalization.Methods:A retrospective comparative study was conducted. Thirty-four patients of MHD with semi-permanent catheter admitted to the department of nephrology of Gansu Provincial Hospital from January 2020 to May 2023 due to CRBSI during non-hospitalization were enrolled. The distribution characteristics of pathogens causing CRBSI in MHD patients during non-hospital period were analyzed. All patients were actively given anti-infection treatment after admission. The general data, laboratory indicators and prognosis during hospitalization were collected through the electronic medical record system. Patients were divided into poor prognosis group (14 cases) and good prognosis group (20 cases) according to the treatment results during hospitalization. Univariate and binary Logistic regression were used to analyze the risk factors affecting the prognosis of patients, and receiver operator characteristic curve (ROC curve) was drawn to evaluate its predictive value for prognosis.Results:A total of 28 pathogenic bacteria were isolated from 34 patients, of which 25 were Gram-positive, Staphylococcus was the most common pathogen, accounting for 82.15% of the total, and 16 strains of Staphylococcus aureus (57.15%), including 6 methicillin-resistant Staphylococcus aureus (MRSA, 21.43%). There were 7 strains of Staphylococcus epidermidis (25.00%), including 3 strains of methicillin-resistant Staphylococcus epidermidis (MRSE, 10.71%). There were 3 strains of Gram-negative bacteria, 1 strain each of Pseudomonas aeruginosa, Escherichia coli and Acinetobacter baumannii. Univariate analysis showed that the fever duration of MHD patients with CRBSI in the poor prognosis group was significantly longer than that in the good prognosis group [days: 8.50 (3.75, 45.00) vs. 2.50 (1.00, 4.75), P < 0.01], serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and random blood glucose (GLU) were significantly higher than those in the good prognosis group [ESR (mm/1 h): 82.36±24.98 vs. 56.95±35.65, CRP (mg/L): 123.45±74.10 vs. 67.35±55.22, GLU (mmol/L): 8.74±3.66 vs. 6.42±1.95, all P < 0.05]. Binary Logistic regression analysis showed that serum CRP was an independent risk factor for poor prognosis in MHD patients with CRBSI [odds ratio ( OR) = 1.020, 95% confidence interval (95% CI) was 1.002-1.038, P = 0.025]. ROC curve analysis showed that the area under the curve (AUC) of serum CRP in predicting poor prognosis of MHD patients with CRBSI was 0.711; when the optimal cut-off value was 104.65 mg/L, the sensitivity was 64.3% and the specificity was 85.0%, indicating that it has good predictive value. Conclusions:Gram-positive bacteria are the main pathogens of CRBSI in MHD patients during non-hospital period. The poor prognosis is mainly related to the high level of serum CRP. Serum CRP level can effectively screen the high-risk group of MHD patients with CRBSI with poor prognosis.

Objective:To investigate the expression, prognostic value and mechanism of MCM10 in hepatocellular carcinoma (LIHC).Methods:The transcriptome and clinical data of hepatocellular carcinoma were obtained from The Cancer Genome Atlas database, and the rank sum test was used to analyze the expression level of MCM10 in tumor tissues and adjacent tissues. Cox regression analysis was used to analyze the relationship between MCM10 expression level and the survival prognosis of patients with hepatocellular carcinoma. Gene set enrichment analysis (GSEA) was utilized for pathway enrichment analysis between MCM10 high and low group gene expression profiles. The effect of MCM10 knockdown on the proliferation of HepG2 cells was determined by cell counting kit-8 (CCK-8) cell viability assay. The effect of MCM10 knockdown on the expression of G1/S-specific cyclin D1 was detected by Western blot.Results:The expression value of MCM10 in hepatocellular carcinoma was 0.709±0.595, and that in adjacent tissues was 0.077±0.094 ( P<0.0 001). Cox regression analysis showed that high expression of MCM10 was a risk factor and prognostic predictor of overall survival ( HR=1.32, 95% CI: 1.19~1.48) and disease-specific survival ( HR=1.40, 95% CI: 1.22~1.61) in LIHC. GSEA analysis showed that the differentially expressed genes were mainly enriched in cell cycle, p53 signaling pathway and positive regulation of G1-S phase transition, et al. CCK-8 assay showed that MCM10 knockdown could inhibit the proliferation of HepG2 cells. Western blot analysis further confirmed that knockdown of MCM10 expression inhibited the expression of cyclin D1 in HepG2 cells. Conclusions:MCM10 is a risk factor for the prognosis of patients with hepatocellular carcinoma, which can promote the proliferation of hepatoma cells through cyclin D1.

Public cell culture platform is an important facility in laboratory animal facilities, providing essential support for scientific research such as the development of animal tumor disease models and transgenic animals. By establishing a public cell culture experimental platform, laboratory animal centers can effectively integrate experimental animals and cell culture resources, optimizing the allocation of scientific research resources to facilitate better research outcomes. The majority of cells cultured in these platforms are used for animal experiments. Contamination or quality issues in these cells not only affect experimental results but also jeopardize the health of experimental animals, potentially leading to microbial infections and contamination of entire animal facilities. Therefore, public cell culture laboratories within experimental animal facilities impose stricter quality control measures than conventional cell culture rooms. This study takes the public cell culture platform at the Laboratory Animal Center of Shanghai Jiao Tong University as a case study to discuss management experiences, focusing on facility maintenance and management, personnel management and quality control of cell biological risk. The aim is to provide useful reference for the management of public cell culture laboratories in experimental animal facilities and other institutions.

Objective:To explore the robust relationship between insomnia and type 2 diabetes mellitus by two-sample Mendelian randomization analysis to overcome confounding factors and reverse causality in observational studies.Methods:We identified strong,independent single nucleotide polymorphisms(SNPs)of insomnia from the most up to date genome wide association studies(GWAS)within European ancestors and applied them as instrumental variable to GWAS of type 2 diabetes mellitus.After excluding SNPs that were significantly associated with smoking,physical activity,alcohol consumption,educational attainment,obesity,or type 2 diabetes mellitus,we assessed the impact of insomnia on type 2 diabetes mellitus using inverse variance weighting(IVW)method.Weighted median and MR-Egger regression analysis were also conducted to test the robustness of the association.We calculated the F statistic of the selected SNPs to test the applicability of instrumental variable and F statistic over than ten indicated that there was little possibility of bias of weak instrumental variables.We further examined the existence of pleiotropy by testing whether the intercept term in MR-Egger regression was significantly different from ze-ro.In addition,the leave-one-out method was used for sensitivity analysis to verify the stability and relia-bility of the results.Results:We selected 248 SNPs independently associated with insomnia at the genome-wide level(P＜5 ×10-8)as a preliminary candidate set of instrumental variables.After clum-ping based on the reference panel from 1000 Genome Project and removing the potential pleiotropic SNPs,a total of 167 SNPs associated with insomnia were included as final instrumental variables.The F statistic of this study was 39.74,which was in line with the relevance assumption of Mendelian randomi-zation.IVW method showed insomnia was associated with higher risk of type 2 diabetes mellitus that po-pulation with insomnia were 1.14 times more likely to develop type 2 diabetes mellitus than those without insomnia(95％CI:1.09-1.21,P＜0.001).The weighted median estimator(WME)method and MR-Egger regression showed similar causal effect of insomnia on type 2 diabetes mellitus.And MR-Egger re-gression also showed that the effect was less likely to be triggered by pleiotropy.Sensitivity analyses pro-duced directionally similar estimates.Conclusion:Insomnia is a risk factor of type 2 diabetes mellitus,which has positively effects on type 2 diabetes mellitus.Our study provides further rationale for indivi-duals at risk for diabetes to keep healthy lifestyle.

Objective To measure the abdominal muscle composition of maintenance dialysis patients using quantitative computed tomography(QCT)and to analyze its relationship with abdominal aortic calcification(AAC).Methods The abdominal CT data of 193 maintenance dialysis patients were analyzed retrospectively and their clinical data were collected.The abdominal muscle composi-tion,including muscle area and muscle fat area,was measured at the middle level of L3 vertebral by QCT.The abdominal aortic calcifica-tion scores(AACs)were calculated using the Agatston method.The groups were grouped according to the quartiles of AACs,and differences in muscle area,muscle fat area and their associated variables were compared between the four groups.The relationship between abdominal muscle composition and AAC was assessed using Spearman rank correlation analysis and partial correlation analysis.Results AACs were positively correlated with age,male,dialysis age,diabetes,hypertension,and abdominal muscle fat area(r=0.555,0.172,0.192,0.348,0.335,0.358,all P<0.05),while no significant correlation was found with abdominal muscle area.A partial correlation analysis controlling for age,sex,dialysis age,hypertension and diabetes showed that AACs were still positively correlated with abdominal muscle fat area(r=0.183,P=0.012).Conclusion Abdominal muscle fat area in maintenance dialysis patients is positively associ-ated with the degree of AAC,and high abdominal muscle fat area is a risk factor for AAC.Enhanced muscle exercise may prevent the risk of vascular calcification in dialysis patients.
