With better awareness and understanding of shift nurses' sleep behaviours, effective interventions can be employed to improve shift nurses' sleep patterns and sleep quality to promote better emotional and health outcomes.

Fasting is known to have many health benefits such as prolonging lifespan and suppression of tumorigenesis. [1][2][3] In the present study, we systematically evaluated the effects of water-only fasting on metabolic-syndrome and age-related risk markers in 45 normal-weight individuals.As shown, a 4.59 kg reduction in body weight, 9.85 cm reduction in waist circumference, and 1.64 kg/m 2 reduction in body mass index (BMI) were observed during a 5-day water-only fast (Figures 1A-1C). After refeeding for 1 month (day 38), body weight, waist circumference, and BMI were still lower than the baseline level . Blood pressure (BP) significantly declined during water-only fasting with diastolic BP declining more than systolic BP and gradually both increased to the baseline level by 98 d (Figures 1D and 1E). Considering many fasting studies showed diastolic BP reduction did not exceed systolic BP reduction, future studies are needed on water-only fasting and BP reduction. Insulin dropped approximately 2.8-fold lower than the baseline level during water-only fasting (Figure 1F). Insulin-like growth factor 1 (IGF-1) decreased by a total of 26% during water-only fasting and decreased more in females than males (Figure 1G and Table S1). Future studies will address the sexual disparity of IGF-1 reduction during water-only fasting. The number of pan T cells, CD4+T cells, CD8+T cells, and B cells decreased during water-only fasting . In contrast, the frequency of Treg cells significantly increased during fasting and still exceeded the baseline level 3 months after refeeding (Figures 1L and 1M). This is an important benefit, since Treg cells have anti-inflammation effects. 4 With regard to thyroid hormones, T4 increased rapidly during fasting, whereas T3 and TSH decreased (Figures 1N-1P). The decreased level of T3 during water-only fasting is of particularly importance since a low T3 level, without impairing thyroid function, is strongly associated with longevity. 5,6 The present studyThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Acute respiratory distress syndrome (ARDS) is a common clinical disorder characterized by pulmonary edema leading to acute lung damage and arterial hypoxemia. Pulmonary fibrosis is a progressive, fibrotic lung disorder, whose pathogenesis in ARDS remains speculative. LincRNA-p21 was a novel regulator of cell proliferation, apoptosis and DNA damage response. This study aims to investigate the effects and mechanism of lincRNA-p21 on pulmonary fibrosis in ARDS. Purified 10 mg/kg LPS was dropped into airways of C57BL/6 mice. Expression levels of lincRNA-p21 and Thy-1 were measured by real-time PCR or western blotting. Proliferation of lung fibroblasts was analyzed by BrdU incorporation assay. Lung and BAL collagen contents were estimated using colorimetric Sircol assay. LincRNA-p21 expression was time-dependently increased and Thy-1 expression was time-dependently reduced in a mouse model of ARDS and in LPS-treated lung fibroblasts. Meanwhile, lung fibroblast proliferation was also time-dependently elevated in LPS-treated lung fibroblasts. In addition, lung fibroblast proliferation could be promoted by lincRNA-p21 overexpression and LPS treatment, however, the elevated lung fibroblast proliferation was further abrogated by Thy-1 overexpression or lincRNA-p21 interference. And Thy-1 interference could elevate cell viability of lung fibroblasts and rescue the reduction of lung fibroblast proliferation induced by lincRNA-p21 interference. Moreover, lincRNA-p21 overexpression dramatically inhibited acetylation of H3 and H4 at the Thy-1 promoter and Thy-1 expression levels in HLF1 cells. Finally, lincRNA-p21 interference rescued LPS-induced increase of lung and BAL collagen contents. LincRNA-p21 could lead to pulmonary fibrosis in ARDS by inhibition of the expression of Thy-1.

Objectives The aim of this systematic reviews was to synthesize the current studies for the effectiveness of intradialytic resistance exercises with usual care on HD people. Design Meta‐analysis of randomized controlled studies. Methods A systematic search of seven electronic databases, including PubMed, EMBASE, the Cochrane Library, Web of Science, WanFang, China National Knowledge Infrastructure (CNKI) and SINOMED, was systematically searched up to May 2018. The reference lists of previously reported systematic review were also checked. Pooled analysis was used to determine effection of intradialytic resistance exercises for haemodialysis people. Physical performance, nutrient intake and quality of life were explored, by comparing the association between effect sizes. Results Fourteen studies of 594 people were included. Compared with control groups, intradialytic resistance exercises significantly improve physical performance included 6‐min walk test, sit‐to‐stand 30 and grip strength. However, no significant improvements were found in nutrient intakes such as dietary protein intake and quality of life.

Mucosal-associated invariant T (MAIT) cells are a subset of innate-like T cells that regulate the immune response via rapidly releasing inflammatory factors, including during progression of some tumors. However, the immunological role of MAIT cells is still unclear in lung cancer. We measured percentage, partial function, and clinical correlation of circulating MAIT cells from lung cancer patients through flow cytometry. Lung cancer patients displayed a high concentration of CD4 + , CD8 + , and activated CD38 + CD8 + MAIT cells, and a decrease of PD1 + double negative (DN) MAIT cells in peripheral blood. Meanwhile, increased levels of interferon-γ, interleukin (IL)-6, and 8 were examined in the serum of lung cancer patients. Importantly, we discovered a statistically positive association between accumulation of CD38 + CD8 + MAIT cells and reduced progression-free survival of lung cancer patients. While preliminary, the altering frequency of MAIT cells might be involved in dysfunctional immune response in lung cancer.
