Objective To understand and explore the lived study feeling and experience of nursing undergraduate students during high- fidelity simulation training so as to provide the evidence of reforming teaching methods and performing the teaching practice of nursing educators. Methods Phenomenological study of qualitative research was used. In- depth interviews were conducted among 4 focus groups. 28 nursing undergraduate students were interviewed to understand their lived study feeling. Results 5 themes were emerged using Colaizzi's phenomenologic method, including cooperating explicitly, integrating theory with practice closely, promoting disease observation ability and nursing decision making, enhancing self-confidence. Conclusions High- fidelity simulation training was beneficial to integrate theory with practice, cultivate students' comprehensive ability and increase clinical practical opportunities.

When the fever was induced by leukocytic pyrogen(LP)on rabbits, we observed the effects of acupuncture on the main point of "Du Channel". At the same time measured the changes of cAMP and cGMP levels in CSF of the animals.It was found that cAMP levels increased (cAMP levels of normal group 18.60?1.56 pmol/ml and experimental group 25.30?1.14pmol/ml,P

Objective To explore the role of sphingosine-1-phosphate receptor (S1PR2) in human coronary artery endothelial cell proliferation in vitro. Methods MTT assay was used to detect cell proliferation in human coronary artery endothelial after treatment of S1P and S1PR2 antagonist JTE-013. Phosphor-ERK and total- ERK level were measured by western blot in endothelial after treatment of S1P and JTE-013. Results 1 μmol/L S1P significantly increased endothelial cells proliferation. S1PR2 antagonist JTE-013 inhibited S1P-induced endothelial cell proliferation in dose-dependent manner. S1PR2 antagonist JTE-013 significantly inhibited S1P-induced phosphor-ERK level in endothelial cells. Conclusion S1PR2 may involve in S1P-induced endothelial cell proliferation through activation of ERK pathway.

AIM:To observe the effects of Sini decoction against pulmonary injury induced by ex vivo ischemia-reperfusion in rats. METHODS: The model of ischemia-reperfusion was established. Twenty-four Sprague-Dawley rats were randomly divided into Sham, I/R, and SND groups. Wet to dry lung weight ratio (W/D), mean pulmonary artery pressure (MPAP), SOD activity and MDA contents in pulmonary perfusate and tissue, NOS activity and NO contents in pulmonary tissue were detected. The pathologic changes in pulmonary tissue were also observed by light microscope. RESULTS: The morphological changes of pulmonary injury were alleviated in SND group. Wet/dry ratio, MPAP and MDA contents in pulmonary perfusate and tissue were significantly lower in SND group after ischemic/reperfusion. SOD activity in pulmonary perfusate and tissue, and NO contents in pulmonary tissue were significantly higher in SND group than those in I/R group. No significant difference in NOS activity in pulmonary tissue among three groups was observed. CONCLUSION: These results indicate that SND may have a protective effect on ischemia-reperfusion injured lung by its antioxidant activity and by adjusting NO level.

Chronic obstructive pulmonary (COPD) has significant extra pulmonary effects, which could induce atrophy of peripheral skeletal muscle and respiratory muscles, and significantly influence the respiratory function and quality of life. Muscle nuclear factor (NF)-κB activation plays a key role in the skeletal muscle atrophy. This article discussed the potential mechanisms on how NF-κB signaling pathway increasing protein breakdown and reducing muscle regeneration. On this basis, we explored the role of NF-κB in skeletal muscle at-rophy in patients with COPD during exercise.

BACKGROUND:Tai Chi exercise can relieve the decreasing lung function and increase exercise tolerance in patients with chronic obstructive pulmonary disease, but some studies found that Tai Chi exercise did not achieve the desired improvement effect in patients. OBJECTIVE:To objectively evaluate the rehabilitation effects in lung function and exercise endurance of Tai Chi exercise on old patients with stable chronic obstructive pulmonary disease. METHODS:A computer-based online retrieval of PubMed, EMBASE, Web of Science, The Cochrane Library, CNKI, VIP and WanFang databases between January 1980 and July 2014 were searched. Randomized control ed trials of Tai Chi intervening in old patients with chronic obstructive pulmonary disease were col ected, including Tai Chi exercise intervention group and drug or physical education control group. RESULTS AND CONCLUSION:A total of 6 randomized control ed trials were included, with 406 patients. The results of Meta-analyses showed that, compared with the control group, Tai Chi exercise obviously improved the percentage of forced expiratory volume in one second/forced vital capacity (MD=4.62, 95%CI:0.73-8.51, P=0.02), the percentage of forced expiratory volume in one second to the prediction value (MD=4.95, 95%CI:0.33-9.57, P=0.04) and 6-minutes walking distance (MD=33.81, 95%CI:6.00-61.62, P=0.02) in patients with chronic obstructive pulmonary disease. Forced expiratory volume in one second showed no significant difference between Tai Chi exercise intervention group and control group (MD=0.02, 95%CI:-0.10, 0.14, P=0.76). Tai Chi exercise could improve the lung function and exercise endurance in old patients with stable chronic obstructive pulmonary disease, and has positive rehabilitation effects.

Objective: The purpose of this tudy was to dynamicly observe the weight and the bone mineral density (BMD) of the unsexed rabbits with a few self-made standardized phantoms. Methods:The eighteen healthy adult female rabbits were measured for their weight and BMD in preunsexed and postunsexed 5 months, 10 months with quantitative CT(QCT). Results:There were 61.1% of rabbits whose weight and BMD decreased after 5 months of the postunsexed and 100% of rabbits whose weight and BMD decreased after 10 months of the operation. Conclusion:QCT can be used to dynamicly observe curative effect of drugs in various periods as well,and it is a good method to study osteoporosis.

Objective To observe the effects of genistein(GEN)on oleic acid(OA)induced lipid accumulationin in H4 ⅡE cells and to discuss the possible mechanism of GEN in the pointof AMPK.Methods H4ⅡE cells were cultured in vitro.The control group(NOR),OA treatment group(MOD group)and GEN treatment group were established according to the experimental requirements.The effects of GEN on the proliferation of H4 Ⅱ E cells were measured with MTT assay.The intraeellular TG mass was quantified spectrophotometrically using TG test kit.Cell protein was determined by DCTM Protein Assay kit.The intracellular TG concentration which was used to evaluate lipid accumulation was corrected using protein content as an internal standard.Western blotting was applied to determine the expression of AMPK and P-AMPK (Thr172).Accordingly the phosphorylation levels of AMPK was by means of P-AMPK(Thr172)/AMPK.Results OA treatment can induce lipid accumulation in H4 Ⅱ E cells while GEN treatment can decrease the intracellular TG concentration through up-regulate the phosphorylation levels of AMPK,though the effect was blocked by Compound C that is the inhibitor of AMPK.Conclusion GEN has anti-accumulation of lipid effect in H4ⅡE cell.The mechanism of GEN protective effect is partially due to AMPK.
