Objective To investigate residents'willingness to use"internet+nursing services"of a community in Xiamen City and provide reference for the code of practice to promote the service.Methods A total of 350 community residents in Xiamen City were investigated by convenience sampling from January to December 2023.The questionnaire was self-designed with regard to their willingness to use"internet+nursing services".Results 336 questionnaires were effectively collected.The total score of willingness to use"internet+nursing services"of community residents in Xiamen City was(68.80±8.73)points,but only 19.6％of residents knew about"internet+nursing services".There were statistically significant differences in willingness to use among community residents with different ages,medical payment type,whether they knew"internet+nursing services"or not,and the number of service items needed(P＜0.05).Among them,age,whether they knew"internet+nursing services"or not and the number of service items needed were the main influencing factors of willingness to use(P＜0.05).Conclusion Community residents in Xiamen City show above the middle level of willingness to use"internet+nursing services".However,the popularity of"internet+nursing services"has a large room for improvement.The publicity to the residents should be strengthened,and the care needs of residents with different demographic characteristics should be considered.The supporting application functions of such platforms should be designed to meet the health needs of community residents,especially elderly patients with great demand for services.

Objective To investigate the effects of B lymphocyte-induced maturation protein-1 ( Blimp-1) on the number and function of splenic lymphocytes.Methods The mice with defective Blimp-1 in T cells were generated by cross-breeding B6.Blimp-1flox/flox mice with B6.Lck-Cre mice.The mononuclear lymphocytes isolated from spleen of T cell conditional Blimp-1 knockout (Blimp-1CKO) mice and wild type ( WT) C57/B6 mice were comparatively analyzed.Alterations of CD4+T and CD8+T cell subsets, the secre-tion of cytokines as well as the expression of C-C chemokine receptor type 7 ( CCR7 ) and Sphingosine-1-phosphate receptor 1 (S1P1) in mice from the two groups were analyzed by flow cytometry.The changes of CD19+B cell subsets were also detected.Results Compared with WT mice, the total numbers of mononu-clear cells, T and B lymphocytes were all significantly increased in Blimp-1CKO mice ( P<0.05) .The ab-solute numbers of CD4+T, CD8+T and CD19+CD5+CD1d+B cells in mice form Blimp-1CKO group were higher than those of the control group (P<0.05), however, no significant differences with the percentages of these cell populations were observed between two groups.Higher numbers and percentages of CD19+CD5+B cells were detected in mice from Blimp-1CKO group (P<0.01).The Blimp-1CKO mice showed increased secretion of IFN-γ, TNF-α, IL-17 and IL-2, but decreased expression of CCR7 on CD8+T cells as com-pared with WT mice (P<0.05).No significant differences with the changes of S1P1 were found between the two groups.Conclusion Blimp-1 played an important role in the maintenance of number, phenotype and function of T cells.Furthermore, not only T cells but also B cell subsets in mice were affected by the dele-tion of Blimp-1 in T cells.
