Objective To explore the preoperative anxiety and health information literacy of patients undergoing percutaneous coronary intervention (PCI), and to analyze the correlation between them, so as to provide reference for promoting psychological care of patients. Methods A total of 221 PCI patients treated in our hospital were selected by convenience sampling, and the preoperative anxiety questionnaire and health information literacy questionnaire were used to investigate. Results The score of health information literacy of PCI patients was (93.38±11.11) points. The score of information morality was the highest (79.1%) and the score of information acquisition and cognition was the lowest (59.3% and 59.9%). The score of anxiety was (27.07±3.96) points before operation, among them, uncertainty score was the highest with (9.73 ± 1.47) points. The scores of all dimensions of health information literacy were negatively correlated with preoperative anxiety scores (r=-0.354~-0.133, P<0.05). Conclusions The preoperative anxiety level of PCI patients is relatively high, the higher the health information literacy level of patients, the lower the preoperative anxiety. Nurses should pay attention to improve the health information literacy of patients, reduce preoperative anxiety to improve the outcome of patients.
ABSTRACT
Objective To investigate the health information literacy (HIL) conditions of patients after percutaneous coronary intervention (PCI) operation and to discuss the influence of HIL on the nursing knowledge acquisition behavior of the patients. Methods A total of 230 postoperative PCI patients who accepted treatment in Cardiology Department of our hospital were selected. General information questionnaire, 2012 National Residents Health Literacy Supervision Investigation Questionnaire-HIL part and nursing knowledge acquisition behavior questionnaire were adopted. Results In this investigation, 230 questionnaires were recovered and 216 of them were effective. HIL level of PCI postoperative patients was 24.1％ (52/216). Differences in HIL levels of patients of different ages, residential areas and educational degrees were of statistical significance (χ2=10.577, 12.657, 37.693, P<0.05). The scores of PCI postoperative exercise method and item analysis of PCI therapy institution and nursing knowledge obtained from medical care personnel, books, Internet and speeches in patients with HIL were 3.40±0.85, 3.35 ± 0.71, 3.37 ± 0.82, 3.75 ± 0.74, 3.54 ± 0.75 and 3.71 ± 0.82. They were significantly higher than the scores of 2.38±0.71, 2.40±0.76, 2.34±0.71, 2.48±0.75, 2.45±0.72 and 2.43±0.78 in the non HIL patients (t=6.657-9.000, P<0.05). The scores of nursing knowledge in coronary heart disease symptoms, PCI postoperative complications and aetiological agent of coronary heart disease,nursing knowledge sources of newspapers, TV and radio, relatives, and nursing knowledge acquisition barriers due to low educational level, incomprehension of terminology and lack of Internet knowledge of the patients with HIL were 2.37± 0.82, 2.63 ± 0.89, 2.42 ± 0.82, 2.37 ± 0.79, 2.50 ± 0.67, 2.48 ± 0.67, 2.46 ± 0.64, 2.46 ± 0.85, 2.54 ± 0.87 and 2.63±0.69. They were significantly lower than the scores of 3.43±0.78, 3.38±0.76, 3.45±0.74, 3.49±0.77, 3.32 ± 0.81, 3.41 ± 0.77 and 3.34 ± 0.83, 3.46 ± 0.70, 3.43 ± 0.74 and 3.41 ± 0.75 in the non HIL patients (t=-5.657-4.690, P<0.05). Conclusions HIL level of PCI postoperative patients is low, and patients in different HIL levels have different nursing knowledge acquisition behaviors.
ABSTRACT
Objective To clone silent information regulator 1 (SIRT1) gene full-length cDNA,construct recombinant eukaryotic expression vector containing SIRT1 gene and its mutant T200I,E420K,so as to lay the foundation for further research of SIRT1 gene function.Methods RT-PCR amplified SIRT1 gene full-length cDNA.PCR products were cloned into the eukaryotic expression vector pcDNA3.1 (+) through double digestion and pcDNA3.1(+)-SIRT1 recombinant plasmid was obtained.Meanwhile,site-directed mutagenesis was applied to build its mutant pcDNA3.1 (+)-T200I and pcDNA3.1 (+)-E420K expression vector.Recombinant plasmid was identified by enzyme digestion and DNA sequencing and the recombinant eukaryotic expression vector of success was screened out.Results SIRT1 gene full-length cDNA was successfully cloned,and pcDNA3.1 (+)-SIRT1 eukaryotic expression vector and its mutant were also successfully constructed.Positive recombinant plasmid sequencing was compared after enzyme digestion,and it was completely consistent with the expected sequence.Transfected 293T cell line was established and HIS tagged SIRT1 protein was expressed.Conclusions We successfully constructed pcDNA3.1 (+)-SIRT1 and its mutant pcDNA3.1 (+)-T200I,pcDNA3.1 (+)-E420K eukaryotic expression vector,which may provide genetic material for biological function study of SIRT1 gene and its mutant T200I,E420K.
