ABSTRACT
Objectives Objectives To investigate how the imbalance of innate lymphoid cells (ILCs)in the peripheral blood of patients with lung adenocarcinoma affects the balance of downstream mononuclear macrophages and T helper (Th) cells, and to identify the impact of the imbalance of ILCs on the immune status and prognosis of lung adenocarcinoma. Methods The peripheral blood of 20 patients with lung adenocarcinoma and normal controls were collected. The percentage of ILCs, mononuclear macrophages and T lymphocyte in peripheral blood were analyzed by flow cytometry. The characteristic cytokine secretion levels of various types of immune cells in peripheral blood were detected by real-time fluorescence quantitative PCR. Results Compared with the normal controls, the proportion of M2 mononuclear macrophages, ILC1 and ILC2 in patients with lung adenocarcinoma was up-regulated, while the proportion of M1 mononuclear macrophages, CD4+ T and CD8+ T was down-regulated. The mRNA expression of related cytokines of M1 mononuclear macrophages and ILC1 were decreased; while the mRNA expression of related cytokines of M2 mononuclear macrophages and ILC2 were increased. Along with the decreased CD4+T cells-associated cytokine T-bet mRNA expression, and the increased GATA3 mRNA expression. Moreover, the expression of PD-1 in CD8+ T cells was also up-regulated. Conclusion The imbalance of ILCs in peripheral blood of patients with lung adenocarcinoma promotes the imbalance of mononuclear macrophages and Th cells, which altogether maintains the immunosuppression in patients with lung adenocarcinoma, and promotes the development of lung adenocarcinoma.

Objective To explore the impact of authentic leadership on silence behavior of nurses and test the mediating effect of organizational support. Methods The 354 valid questionnaires were collected using the a cross-sectional survey with Authentic Leadership Questionnaire, Perceived Organizational Support Scale and Silence Behavior Scale between September to November in 2015, using the multiple line hierarchical regression analysis to test the relationship between variables. Results Authentic leadership could significantly promote the perceived organizational support of subordinate nurses (β= 0.543, P<0.01), which in turn, significantly restrain silence behavior of subordinate nurses (β=-0.323, P<0.01), the perceived organizational support completely mediate the relationship between authentic leadership and silence behavior (β=0.175, P<0.01). Conclusions By constructing the supporting work environment, authentic leadership can eliminates nurses′ voice worry, motivates the voice motivation and efficiency, in turn to break the silence. This article propose the action mechanisms from three perspectives.
ABSTRACT
According to the related requirements of medical technology clinical application management, the specific implementation approaches of surgery physicians surgery permission management were made, including establishing surgery classification project directory library, developing surgery classification management system and the surgery permission declared, and audit program, and investigating to determine the steps of surgery permission owned by surgery physicians currently, and finding problems and solution measures in implementation surgery permission management. To prevent surgical risk, improve the quality of operation, and evaluate surgical doctors scientifically, it provides management experience and references.
