Objective To discuss the barriers influencing the application of evidence-based nursing. Methods Nine hundred nurses from August 2013 to February 2014 were selected from five polyclinics in Shenzhen by randomly cluster sampling according to different departments and wards. We carried out the survey with the Chinese version of cognitive of impairment of nursing scientific research scale. Results The sores of 4 dimesions of scientific application of evidence-based nursing from high to low were effectiveness and system of research, resource to evidence-based nursing, quality of research and attitude and ability of nursing staff. The main barriers in applying scientific research payoffs by the nursing staff included the deficient resource and equipment provided by hospitals (68.09%), the jumbled medical development information confused the nurses in selecting related reference (66.75%), failing to put the scientific achievements into practice (66.01%),insufficient time to actualize new ideas (64.15%), and difficulty in obtaining the reference of scientific research (64.04%). Conclusion The barriers to scientrfic application of evidence-based nursing were the deficient resource and time and difficulties to find evidence. The nursing policy makers should adopt efficient measures aimed at the difficulties the nursing staff in applying their research results, thereby popularize the application of research achievements in hospitals.

Objective To investigate the changes and clinical significance of cerebrospinal fluid (CSF) non-protein-bound iron and malondialdehyde(MDA) in preterm infants with severe intraventricular hemorrhage (IVH) after serial lumbar punctures.Methods Non-protein-bound iron and MDA of CSF in twenty severe IVH preterm infants with first and end lumbar puncture were examined respectively.The control samples were determined for once from first to second week after birth.Results Both Non-protein-bound iron and MDA levels of the first CSF sample in twenty severe IVH preterm infants were higher than that in control[(0.66±0.38)μmol/L vs (0.24±0.12)μmol/L(P<0.01);(1.21±0.41)μmol/L vs (0.89±0.35)μmol/L(P<0.05)].Non-protein-bound iron levels of first and end CSF sample in severe IVH with posthemorrhagic ventricular dilatation (PHVD) were both higher than those without PHVD [(0.75±0.34)μmol/L vs (0.54±0.31)μmol/L;(0.57±0.21)μmol/L vs (0.35±0.18)μmol/L](P<0.05).However,there was no significant difference in MDA levels between both groups.The levels of non-protein-bound iron of end CSF in severe IVH with and without PHVD were significantly lower than those of the first CSF samples (P<0.05),while,there was no significant difference in MDA levels between the end and first CSF samples.Conclusion The non-protein-bound iron and MDA of CSF in severe IVH preterm infants were both significantly increased,non-protein-bound iron and oxygen free radicals may be involved in the preterm brain injury.Serial lumbar punctures can lower the levels of non-protein-bound iron in CSF.

Proteome is defined as all proteins expressed in a cell, a tissue or an organism. Proteomics, a science of understanding the life activity law at the whole protein level, takes proteome as a research object; it is also a scientific method for quantitative detection of one or more protein populations or proteomes in a cell or tissue. Cerebral ischemic preconditioning has been one of the research hotspots in the field of neuroscience for decades. Its neuroprotec-five mechanism is associated with the changes of protein expression levels after cerebral ischemia, Therefore, proteomics has become more and more important in its mechanism study. This article mainly presents the major techniques of proteomics and their application in the studies of cerebral ischemic preconditioning.
