RESUMO
Objective:To analyze the level of self-management and its influencing factors in patients with systemic lupus erythematosus (SLE).Methods:A cross-sectional study. From January to December 2021, patients with SLE in the Department of Rheumatology and Immunology in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine were selected as the study objects by convenience sampling method. A total of 135 questionnaires were distributed in this study, 135 were recovered, and 128 were valid. The general data of the patients were collected, and the self-management level, self-efficacy, family care and meaning in life of the patients were evaluated with the chronic disease self-management behavior scale, general self-efficacy scale (GSES), family adaption partnership growth affection resolve index (APGAR) and the meaning in life questionnaire (MLQ). Multiple linear regression analysis was applied to explore the factors affecting the self-management of SLE patients.Results:The total score of chronic disease self-management behavior scale in the 128 SLE patients was (28.77±6.58) points. Pearson correlation analysis showed strong correlation between self-efficacy, sense of life meaning and self-management ( r=0.748, 0.717, both P<0.001), there was a moderate correlation between family care and self-management ( r=0.560, P<0.001). Multiple linear regression analysis showed that educational level ( β′=0.457), disease activity ( β′=-0.211), self-efficacy ( β′=-0.372), family care ( β′=-0.510), meaning in life ( β′=-0.386) were influencing factors of self-management level in patients with SLE (all P<0.05). Conclusions:The self-management level of SLE patients needs to be improved. Disease activity, self-efficacy, meaning in life and other factors can affect the patients′ self-management level.
RESUMO
We expressed multi-epitope chimeric protein of CARDS toxin protein of Mycoplasma pneumonia (Mp) in prokaryotic cells,and purified and investigated its immunoreactivity.A recombinant multi-epitope chimeric gene including ten critical epitopes was connected by linker and cloned into prokaryotic expression vector pET-28a(+),and transformed into E.coli BL21(DE3) cells for expression under induction of IPTG.The antigenicity of expressed recombinant protein was identified with 6 × His monoclonal antibody and human positive serum by Western blot.The recombinant expression vector pET-CARDS was constructed and the about 30 kDa recombinant chimeric protein expressed in BL21(DE3) successfully.Western blot analysis showed that it can react respectively with 6 × His monoclonal antibodies and human positive serum.This study showed that the chimeric CARDS protein has an obvious immunoreactivity and a potential to be a new antigen for the diagnosis of Mp infection.
