RESUMO
Objective:To explore the application effect of magnetic service concept in clinical nursing for patients with acute gastroenteritis.Methods:A total of 101 patients with acute gastroenteritis undergoing magnetic service concept intervention in gastroenterology department of Lishui Central Hospital were selected as study group from January 2019 to January 2020, other 97 patients with acute gastroenteritis undergoing routine nursing intervention were enrolled as control group from January to December 2018. The scores of Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), self-care ability and quality of life before and after intervention were observed and compared between the two groups. The scores of nursing satisfaction were recorded and compared between the two groups.Results:After nursing, HAMA and HAMD scores in study group were (13.39 ± 4.56) and (17.89 ± 6.63) points, which were significantly lower than those in control group (18.60 ± 6.79) and (21.51 ± 6.03) ( t values were 6.36 and 4.11, P<0.05). After nursing, scores of self-concept, self-responsibility, self-care skills and health awareness in study group were (79.12 ± 4.98), (79.85 ± 5.47), (80.22 ± 3.89) and (76.25 ± 5.98) points, which were higher than those in control group (52.08 ± 3.63), (58.88 ± 7.25), (57.65 ± 3.62), (54.12 ± 5.06) points (t values were 23.06-43.41, P<0.05). After nursing, scores of physiology, mentality, emotion and social contact in study group were (69.14 ± 4.21), (82.13 ± 6.12), (71.25 ± 5.28) and (82.95 ± 7.22) points, which were higher than those in control group (60.41 ± 3.26), (69.57 ± 4.26), (57.13 ± 3.21), (68.07 ± 5.14) points (t values were 16.27-33.63, P<0.05). The scores of satisfaction with life care, regular wards inspections, bell calling, service attitudes and health education in study group were (90.40 ± 6.80), (91.38 ± 6.82), (90.22 ± 4.96), (90.88 ± 5.56) and (92.46 ± 6.38) points, which were higher than those in control group (81.22 ± 5.83), (80.44 ± 4.25), (82.12 ± 4.65), (83.24 ± 4.56), (82.06 ± 3.55) points (t values were 10.18-14.09, P<0.05). Conclusions:The magnetic service concept can improve psychological status and quality of life in patients with acute gastroenteritis, enhance self-care ability and nursing satisfaction.
RESUMO
<p><b>OBJECTIVE</b>To study pathological and therapeutical problems concerning myocardial cell mitochondria changes during myocardial cell hypertrophy by culturing rat primary myocardial cells.</p><p><b>METHOD</b>Primary myocardial cells were seperated and cultured together with angiotensin II (Ang II) for 72 or 96 hours. The total protein content with the BCA method and the photography and measurement of cell diameter with inverted microscope reflected myocardial cell proliferation. The mitochondrial membrane potential (Delta Psi m) with fluorescence microscope, the mitochondrial single amine oxidase (MAO) activity with spectrophotometer, the mitochondrial cytochrome oxidase (COX) activity and the injury percentage of mitochondrial outer membrane with microplate reader and the contents of ATP, ADP, AMP with high performance liquid chromatography reflected the injury and energy metabolism of myocardial cell mitochondrial structure and function when being cultured together with Ang II. On that basis, cells were treated with Astragali Radix injection and valsartan for observing pharmacological effects on mitochondrial structure and function in restructured myocardial cells.</p><p><b>RESULT</b>In 72 h and 96 h, compare with the control group, the model group showed significantly increased total protein content and enlarged myocardial cell diameter. During the course of proliferation, the myocardial cell MAO activity and the injury percentage of mitochondrial outer membrane were significantly increased, with significant decrease in mitochondrial COX activity, mitochondrial Delta Psi m and the content of ATP, ADP and rise in the content of AMP. Astragali Radix injection and valsartan reduced myocardial cell total protein content and cell diameter caused by Ang II, decreased myocardial cell MAO activity, significantly increased mitochondrial COX activity and the content of ATP and ADP, and decreased the content of AMP.</p><p><b>CONCLUSION</b>During the process of myocardial hypertrophy, the injury of mitochondrial structure and function and the changes in myocardial cell energy metabolism injury occurred after the injury of mitochondria. Astragali Radix injection and valsartan can reverse myocardial cell mitochondrial structure and function during myocardial cell hypertrophy caused by Ang II. Reversion of myocardial cell hypertrophy and restructuring of myocardial cells helps improve energy metabolism of the myocardial cells.</p>
