Objective To explore the influencing factors of self-perceived burden(SPB) among patients with cerebral infarction.Methods A total of 108 patients were included in the study,they were investigated by a self-designed demographic questionnaire and Self-Perceived Burden Scale(SPBS).Chisquare analysis,t test and multiple regression analysis were used to explore the influencing factors of SPB.Results The SPB of patients with cerebral infarction was (36.72±4.23) points.Self-care ability,hemiple-gia,language barriers and times of hospitslization were the influencing factors of SPB according to the mul-tiple regression analysis.Conclusions The patients with cerebral infarction have obvious SPB,which is influenced by multiple factors.Nurses should take proper measures to alleviate the patients' SPB.

Objective To evaluate the correlation between family coherence and adaptation and selfesteem among patients with cerebral infarction.Methods A total of 253 patients were included in the study,they were investigated by Rosenberg Self-Esteem Scale and Family Coherence and Adaptation Scale.Results Self-esteem was significantly positively correlated with real family coherence and real family adaptation,while significantly negatively correlated with dissatisfaction of family coherence and dissatisfaction of family adaptation.Age,family income and the course of disease were the influencing factors of family coherence and adaptation and self-esteem.Conclusions The self-esteem was conrelated with family coherence and adaptation among patients with cerebral infarction.

Objective To investigate the clinical significance of multi-tumor biomarkers combined variation in patients with idiopathic pulmonary fibrosis(IPF).Methods Multiple serum tumor biomarkers,including AFP,CEA,CA125,CA153 and CA199 were detected in 25 patients with IPF and 23 healthy controls by chemiluminescence method,and the blood gas analysis,pulmonary function parameters and other clinical data were also collected simultaneously.Results All serum biomarkers measured in this study were significantly higher in IPF group than control,AFP([2.41±0.95]μg/L vs.[1.29±0.13]μg/L,t=4.32,P＜0.05),CEA([7.12±2.68]μg/L vs.[2.14±0.57]μg/L,t=3.69,P＜0.05),CA125([118.52±31.64]kU/L vs.[23.97±8.47]kU/L,t=4.15,P＜0.05),CA153([47.58±14.57]kU/L vs.[9.24±4.21]kU/L,t=5.87,P＜0.05),and CA199([165.78±21.13]kU/L vs.[14.51±5.74]kU/L,t=4.22,P＜0.05).The serum levels of AFP,CEA,CA125,CA153,CA199 were negatively correlated with blood oxygen pressure(r=-0.15--0.55,Ps＜0.05),vital capacity(r=-0.09--0.49,Ps＜0.05),lung diffusion capacity(r=-0.17--0.61,Ps＜0.05),while no significant correlations were found between different biomarker levels and ESR and CRP(Ps＞ 0.05).In addition,the serum level of different tumor markers increased along with the progress of pulmonary fibrosis,which showed statistical significance(Ps＜0.05).After hormone medication therapy,the serum tumor marker levels decreased significantly in IPF patients[AFP[2.41±0.95]μg/L vs.[1.67±1.22]μg/L,t=5.41,P＜0.05,CEA([7.12±2.68]μg/L vs.[3.75±1.96]μg/L,t=4.63,P＜0.05,CA125([118.52±31.64]kU/L vs.[53.22±13.56]kU/L,t=3.97,P＜0.05),CA153(47.58±14.5 vs.19.35±8.74 kU/L,t=5.15,P＜0.05),CA199(165.78±21.13 vs.58.85±17.31 kU/L,t=6.34,P＜0.05)].Conclusion Multiple serum tumor biomarkers significantly increased in patients with IPF,and had a close correlation with lung function damage.The changes of these biomarkers indicated the progress of pulmonary fibrosis,which served as the predictors of poor prognosis.

Objective:To separate human kidney phosphoproteome by two-dimensional gel electrophoresis.Methods: The phosphorylated proteins from human kidney tissues were enriched with phosphate metal affinity chromatography(PMAC) resin.After being concentrated and desalted,the samples were separated by isoelectric focusing on first dimension and SDS electrophoresis on second dimension.Results: The phosphorylated proteins were successfully extracted from human kidney tissues and were separated by two-dimensional gel electrophoresis.Conclusion: Phosphoprotein enrichment technique combined with two-dimensional gel electrophoresis is an effective approach to study phosphoproteome,laying a foundation for further investigation of human kidney phosphoproteins.

Objective To study the different expressions of cancerous inhibitor of protein phosphatase 2A (CIP2A)in non-small cell lung cancer (NSCLC),investigate its clinical significance and potential prognostic value.Methods Immunohistochemical and real-time polymerase chain reaction (PCR)were used to detect the expressions of CIP2A mRNA and protein in two groups of sixty paired NSCLC specimens and adjacent non-cancer tissues.The relationship between its expression and clinical pathological data and prognostic factors were analysed. Results The expression of CIP2A mRNA in NSCLC specimens was higher than those in adjacent non-cancer tissues(P<0.01 );The expression of CIP2A protein in NSCLC tissues was significantly higher than that in the corresponding adjacent non-cancer tissues (P<0.01 ).The expression of CIP2A was closely correlated with the differentiation and lymph node metastasis of NSCLC tissues (P<0.05 ),while incorrelated with sex,age,pathematology type,tumor size and tumor node metastasis (TNM)stage.Conclusion CIP2A highly expresses in NSCLC,and the expression of CIP2A will increase with the differentiation and lymph node metastasis of NSCLC tissues.The expression of CIP2A and lymph node metastasis can be used as an independent risk factor for the prognosis of patients with NSCLC.

Currently,the overall situation of information literacy level of researchers in hospitals is generally low.This paper explores the connotation of information literacy and stresses the importance of information literacy cultivation for scientific researchers.Suggestions are also made for cultivation of information literacy.
