Objective To study the expression of SGK1 in T lymphocytes from pediatric asthma,and the effect of SGK1 on the differentiation of T cells,also to explore the function of SGK1 regulating the differen-tiation of T subset in pediatric asthma. Methods Twenty-eight children with asthma were recruited in Xi′an children′s hospital and divided into moderate group and severe group according to diagnostic guideline of asth-ma. The serum levels of IL-4,IL-13 and IL-17A were analyzed by ELISA. The CD4 +T cells from PBMC and na?ve T cells were selected using magnetic beads. Na?ve T cells were differentiated in vitro under cytokines. SGK1 expression were analyzed with Real-time PCR. The ability of Th2 and Th17 on secreting IL-4 and IL-17A were detected after SGK1 was inhibited by siRNA. In vivo,shRNA-SGK1 Na?ve T cells were transferred into the mice asthma models by intravenous injection. The airway inflammation were observed in shRNA-SGK1 Na?ve T models. Results Compared with healthy children,the serum levels of IL-4、IL-13 and IL-17A increased signifi-cantly in the children with asthma. Importantly,the levels of these three cytokines were much higher with the de-velopment of asthma. SGK1 were up-regulated remarkably in CD4 +T cells from the children with asthma and were positively correlated with IL-13 and IL-17A. Besides,SGK1 expression increased in the differentiated Th2 and Th17 in vitro,but had no change in the differentiated Th1. The levels of IL-4 and IL-17A associated with Th2 and Th17 decreased after SGK1 was inhibited by siRNA. Similarly,In vivo,the serum levels of IL-13 and IL-17A and airway inflammation were reduced in shRNA-SGK1 Na?ve T models. Conclusion The over-expres-sion of SGK1 in pediatric asthma enhances the asthma progress by promoting the differentiation of T subsets.

BACKGROUND AND OBJECTIVES: This study aims to investigate the significance of changes in the expression 11β-hydroxysteroid dehydrogenase (11β-HSD) and glucocorticoid receptor (GR) for the development of Kawasaki disease (KD). SUBJECTS AND METHODS: Real-time polymerase chain reaction was performed to determine the mRNA expression levels of GR and 11β-HSD in peripheral blood monocytes, both in the acute phase of the disease and after treatment. Western blotting was performed to determine the protein expression levels of GR and 11β-HSD. RESULTS: The expression levels of GRβ, GRβ, and 11β-HSD1 mRNA in the acute phase were significantly higher than levels at baseline (p<0.01) and after treatment (p<0.05). The 11β-HSD2 mRNA levels were lower in the acute phase than in the normal group (p<0.01), and they were significantly higher after treatment than before (p<0.01). Western blot results were consistent with the real-time PCR results. The coronary artery lesion group exhibited significantly different 11β-HSD2 expression levels from that of the group with normal coronary arteries (p<0.01). CONCLUSION: GR and 11β-HSD expression changes in the acute phase of KD are important factors for regulating inflammatory responses in KD.

Objective To investigate nurses' scientific research competency and training demand in Chinese tertiary hospital.Methods It was a multi-stage large-scale survey.A total of 27 335 nurses from 22 provinces/autonomous regions/municipalities were recruited to complete the self-designed questionnaire,including demographic data(7 items),scientific research competency(objective index of 4 items,and subjective index of 6 subscales with 40 items),and training demand evaluation(6 subscales with 16 items).Results There were 1 130(4.14％) nurses who had managed or were managing the research projects as principal investigators(PIs),2 147(7.85％)nurses who had attended or were attending research programs,1 463(5.35％) nurses had published papers,and 557(2.04％) nurses obtained patents.The self-evaluated competency score was 25.00 (12.50,37.50)(rangedfrom 0 to 100)and training demand score was 53.13(37.50,75.00)(ranged from 0 to 100).Conclusion The nurses' scientific research competency should be improved and they had strong training demands.In order to improve nurses' research competency and quality,nursing administrators should pay more attention to post-graduate training focusing on research competency.

Objective:To investigate the role of miRNA-4298/PADI4/p53 signal axis in mediating 4f-induced apoptosis of leukemia cells.Methods:The cell growth density was observed under inverted microscope and the proliferation of leukemia cells was detected by CCK-8 counting assay. The expression of PADI4 and P53 at mRNA level was detected by qRT-PCR. Cell cycle and apoptosis were measured with flow cytometry. The expression of PADI4, P53, Bcl-2, Bax, caspase-3 and caspase-9 at protein level was detected by Western blot. Differential miRNA and mRNA expression profiles was detected by next generation sequencing. Databases such as TargetScan were used to predict the potential upstream and downstream genes of PADI4. A luciferase reporter assay was used to detect the 3′UTR of PADI4 targeted by miRNA-4298. Cell transfection assay was used to detect the effect siRNA, PADI4 vector, miRNA mimics and miRNA inhibitor in interference and rescue.Results:Nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor 4f could inhibit the proliferation of THP-1, K562 and U937 cells, and induce the apoptosis of these leukemia cells. It downregulated the expression of PADI4 mainly through the binding activity of miRNA-4298 to miRNA sponges, which resulted in the proliferation inhibition and apoptosis of leukemia cells. The inhibited proliferation and apoptosis of leukemia cells by 4f were associated with the increase of P53 expression after the decrease of PADI4 expression. The PADI4-dependent upregulation of P53 led to the ratio inversion of downstream Bcl-2/Bax, which activated caspase-3 or caspase-9 to induce the apoptosis of leukemia cells.Conclusions:The apoptosis of leukemia cells induced by Nrf2 inhibitor 4f was mainly associated with the miRNA-4298/PADI4/p53 axis, suggesting that it might be a novel signaling pathway for targeted therapy.
