BACKGROUND Preoperative supplementation with immunonutrients, including arginine and n-3 fatty acids, has been shown in a number of systematic reviews to reduce infectious complications in patients who have undergone gastrointestinal surgery. Limited information, however, is available on the benefits of nutritional supplementation enriched with arginine and n-3 fatty acids in patients undergoing liver resection.AIM To evaluate the effects of preoperative nutritional supplementation enriched with arginine and n-3 fatty acids on inflammatory and immunologic markers and clinical outcome in patients undergoing liver resection.METHODS Thirty-four patients undergoing liver resection were randomized to either five days of preoperative Impact? [1020 kcal/d, immunonutrition(IMN) group], or standard care [no supplementation, standard care(STD) group]. Nutritional status was measured at study entry by subjective global assessment(SGA).Functional assessments(grip strength, fatigue and performance status) were carried out at study entry, on the day prior to surgery, and on postoperative day(POD) 7 and 30. Inflammatory and immune markers were measured at study entry, on the day prior to surgery, and POD 1, 3, 5, 7, 10 and 30. Postoperative complications were recorded prospectively until POD30.RESULTS A total of 32 patients(17 IMN and 15 STD) were analysed. All except four patients were SGA class A. The plasma ratio of(eicosapentaenoic acid plus docosahexaenoic acid) to arachidonic acid was higher in IMN patients on the day prior to surgery and POD 1, 3, 5 and 7(P < 0.05). Plasma interleukin(IL)-6 concentrations were elevated in the IMN group(P = 0.017 for POD7). No treatment effect was detected for functional measures, immune response(white cell count and total lymphocytes) or markers of inflammation(C-reactive protein,tumour necrosis factor-α, IL-8, IL-10). There were 10 patients with infectious complications in the IMN group and 4 in the STD group(P = 0.087). Median hospital stay was 9(range 4–49) d in the IMN group and 8(3-34) d in the STD group(P = 0.476).CONCLUSION In well-nourished patients undergoing elective liver resection, this study failed to show any benefit of preoperative immunonutrition. 展开更多

The factors that determine fibrosis progression or normal tissue repair are largely unknown.We previously demonstrated that autophagy inhibition-mediated epithelial-mesenchymal transition(EMT)in human alveolar epithelial type Il(ATIl)cells augments local myofibroblast differentiation in pulmonary fibrosis by paracrine signaling.Here,we report that liver kinase B1(LKB1)inactivation in ATIl cells inhibits autophagy and induces EMT as a conse-quence.In IPF lungs,this is caused by the down-regulation of CAB39L,a key subunit within the LKB1 complex.3D co-cultures of ATIl cells and MRC5 lung fibroblasts coupled with RNA sequencing(RNA-seq)confirmed that paracrine signaling between LKB1-depleted ATIl cells and fibroblasts augmented myofibroblast differentiation.Together,these data suggest that reduced autophagy caused by LKB1 inhibition can induce EMT in ATIl cells and contribute to fibrosis via aberrant epithelial-fibroblast crosstalk. 展开更多

Progressive lung fibrosis is characterized by dysregulated extracellular matrix(ECM)homeostasis.Understand-ing of disease pathogenesis remains limited and has prevented the development of effective treatments.While an abnormal wound-healing response is strongly implicated in lung fibrosis initiation,factors that determine why fi-brosis progresses rather than regular tissue repair occur are not fully explained.Within human lung fibrosis,there is evidence of altered epithelial and mesenchymal populations as well as cells undergoing epithelial-mesenchymal transition(EMT),a dynamic and reversible biological process by which epithelial cells lose their cell polarity and down-regulate cadherin-mediated cell-cell adhesion to gain migratory properties.This review will focus on the role of EMT and dysregulated epithelial-mesenchymal crosstalk in progressive lung fibrosis. 展开更多

背景最近一项系统性综述表明,迄今仍缺乏观察低维生素D浓度与多种疾病关系的随机对照研究。即使是既往研究维生素D相关骨代谢和肌肉功能结局的研究,结论亦不一致。实际上,关于血清25-羟维生素D的最佳浓度,一直存在争议。
