Objectives:To develop modified prehospital stroke scales and to evaluate their predictive value for in-hospital acute large vessel occlusion (LVO) stroke.Methods:Patients admitted to Dongtai People's Hospital due to non-stroke-related diseases and activated the in-hospital stroke green channel due to suspected stroke symptoms during hospitalization from January 2015 to December 2022 were included retrospectively. According to the final imaging diagnosis, they were divided into LVO group and non-LVO group. The five prehospital stroke scales included Field Assessment Stroke Triage for Emergency Destination (FAST-ED), Rapid Arterial Occlusion Evaluation (RACE), Los Angeles Motor Scale (LAMS), Cincinnati Prehospital Stroke Severity Scale (CPSSS), and Prehospital Acute Stroke Severity Scale (PASS). Multivariate logistic regression analysis was used to determine independent predictive factors of LVO in patients with in-hospital stroke, and incorporating them into the prehospital stroke scale to develop modified scales. The receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of the modified scales. Results:A total of 174 patients with in-hospital stroke were enrolled, including 92 males (52.9%), aged 65.7±11.9 years. Fifty-four patients (31.0%) had LVO, and 59 (33.9%) had a surgical history within 3 days before the onset of stroke, mainly cardiopulmonary surgeries. Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio 2.940, 95% confidence interval 1.387-6.230; P=0.005) and recent history of cardiopulmonary surgery (odds ratio 6.861, 95% confidence interval 2.437-11.315; P<0.001) were the independent predictive factors of LVO in patients with in-hospital stroke. According to the β coefficient and ROC curve, they were assigned a score of 1 and included in the prehospital stroke scale. The area under the curve of the modified scale for predicting LVO (mRACE: 0.917; mFAST-ED: 0.865; mPASS: 0.859; mCPSSS: 0.853; mLAMS: 0.907) was significantly higher than the corresponding original scale (RACE: 0.888; FAST-ED: 0.820; PASS: 0.786; CPSSS: 0.810; LAMS: 0.859) (all P<0.05). Conclusion:The modified scales based on the prehospital stroke scales can significantly improve the predictive value of in-hospital acute LVO stroke compared to the original prehospital stroke scales.

Nursing skill competitions are the wind vane for clinical nursing development, and the teaching concepts, proposition forms, and evaluation systems demonstrated by competitions have a strong reference value for nursing teaching. This article introduces the knowledge selection and integration from nursing-related courses according to the problems and objectives to be solved by drawing on the STEM education concept in comprehensive nursing practical training in the context of integration of competition and education. Realistic problem scenarios can be created with clinical cases as the carrier or main line, and then the Tanner clinical judgment model is used to guide students to conduct a comprehensive analysis of cases, thereby helping students to develop clinical thinking ability and comprehensive practical skills, so as to bridge the gap between the contents learned at school and nursing work in clinical practice and help nursing students adapt to clinical practice as soon as possible.

Objective To build the early predictive model for chronic kidney disease(CKD)in hypertension and diabetes patients in the community.Methods The CKD patients were recruited from 4 health care centers in 4 urban areas in Kunming.The control group was residents without hypertension and diabetes(n = 1267).The disease group was residents with hypertension and/or diabetes(n = 566).The questionnaire survey,physical examination,laboratory testing,and 5 SNPs gene types in the PVT1 gene.The risk factors,which were filtered with logistics regression,were used to build predictive models.Four machine learning algorithms were built:support vector machine(SVM),random forest(RF),Na?ve Bayes(NB),and artificial neural network(ANN)models.Results Thirteen indicators included in the final diagnostic model:age,disease type,ethnicity,blood urea nitrogen,creatinine,eGFR from MDRD,ACR,eGFR from EPI2009,PAM13 score,sleep quality survey,staying-up late,PVT1 SNP rs11993333 and rs2720659.The accuracy,specificity,Kappa value,AUC of ROC,and PRC of ANN are greater than those of the other 3 models.The sensitivity of RF is the highest among 4 types of machine learning.Conclusions The ANN predictive model has a good ability of efficiency and classification to predict CKD with hypertension and/or diabetes patients in the community.

Objective:To discuss the effect of apolipoprotein C1(APOC1)expression on the proliferation and apoptosis of the hepatocellular carcinoma cells,and to preliminarily clarify the related molecular mechanism.Methods:The expression level of APOC1 mRNA in hepatocellular carcinoma tissue and its relationship with the prognosis of the patient were analyzed by The Cancer Genome Atlas(TCGA)Database;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of APOC1 mRNA in different hepatocellular carcinoma cells;the human liver cancer HepG2 cells with low APOC1 expression were selected as the subjects.The HepG2 cells were transfected with pcDNA3.1-APOC1 plasmid to over-express APOC1(APOC1 over-expression group),and the HepG2 cells transfected with empty vector pcDNA3.1 were regarded as control group.MTS assay and 5-ethynyl-2'-deoxyuridine(EdU)staining were used to detect the proliferative activities and proliferation rates of the cells in two groups;Transwell chamber assay was used to detect the numbers of migration cells in two groups;flow cytometry and TUNEL assay were used to detect the percentages of the cells at different cell cycles and apoptotic rates in two groups;Western blotting method was used to detect the expression levels of extracellular regulated protein kinase(ERK),phosphorylated ERK(p-ERK),protein kinase B(AKT),phosphorylated AKT(p-AKT),B-cell lymphoma-2(Bcl-2),and cleaved cysteinyl aspartate specific proteinase-3(cleaved caspase-3)proteins in the cells in two groups.Results:The TCGA Database results showed that the expression level of APOC1 mRNA in hepatocellular carcinoma tissue was lower than that in normal liver tissue(P<0.05),and the patients with low expression of APOC1 mRNA had poor prognosis.The RT-qPCR results showed that the expression level of APOC1 mRNA in the HepG2 cells was the lowest,and the HepG2 cells were chosen for the subsequent research.Compared with control group,the proliferative activity and proliferation rate of the cells in APOC1 over-expression group were decreased(P<0.05 or P<0.01),the number of migration cells was decreased(P<0.01),and the percentage of the cells at S phase and the apoptotic rate were significantly increased(P<0.01).Compared with control group,the expression levels of p-ERK,p-AKT,and Bcl-2 proteins in the cells in APOC1 over-expression group were significantly decreased(P<0.05),and the expression level of cleaved caspase-3 protein was increased(P<0.01).Conclusion:High expression of APOC1 can inhibit the proliferation of the human liver cancer HepG2 cells and induce the apoptosis,and its mechanism may be related to inhibition of the expressions of p-ERK,p-AKT,Bcl-2 proteins and promotion of the expression of cleaved caspase-3 protein.

Objective:To analyze the multiple locus variable number tandem repeat analysis (MLVA) genotype polymorphism of Bacillus (B.) anthracis and establish a MLVA genotype database of B. anthracis in China. Methods:B. anthracis strains isolated from different sources in China since 1947 were collected. Genotype identification was carried out using the MLVA15 genotyping protocol based on 15 variable number tandem repeat loci. The genotypes were uniformly numbered and named. The distribution characteristics of the MLVA genotypes of strains were analyzed. Software Bionumerics was used to construct clustering diagrams to analyze the genetic relationships. Results:The MLVA15 clustering analysis subdivided the isolates into 4 major groups and 91 genotypes, 54 of which were unique to China. The genotypes from MLVA15-CHN1 to MLVA15-CHN6 were widely distributed throughout China and in all eras, while other genotypes were restricted to certain regions or eras.Conclusions:This study established a MLVA genotype database of B. anthracis, which provides basis for the understanding of MLVA genetic polymorphisms and the control and molecular source tracing of the anthrax outbreaks in China.
