Effect of compound Danshen dripping pills combined with atorvastatin on restenosis after angioplasty in rabbits / 南方医科大学学报

<p><b>OBJECTIVE</b>To study the effect of compound Danshen dripping pills and atorvastatin on restenosis after abdominal aorta angioplasty in rabbits.</p><p><b>METHODS</b>Rabbit models of abdominal aorta restenosis after angioplasty were established and treated with saline (group A), compound Danshen dripping pills (group B), atorvastatin (group C), or compound Danshen dripping pills plus atorvastatin (group D). HE staining was used to determine the thickness of arterial intimal hyperplasia and assess the morphological changes of the narrowed artery. Immunohistochemistry was employed to detect the expression of nuclear factor-κB (NF-κB) and monocyte chemoattractant protein-1 (MCP-1).</p><p><b>RESULTS</b>Compared with group A, the 3 treatment groups showed significant increased vascular cavity area and reduced intimal area and percentage of intimal hyperplasia (P<0.05). The vascular cavity area, intimal area and percentage of intimal hyperplasia levels differed significantly between group D and groups B and C (P<0.05). Immunohistochemistry showed a significant reduction of the expression rate of NF-κB and MCP-1 in the 3 treatment groups compared with group A (P<0.05), and the reduction was especially obvious in group D (P<0.05).</p><p><b>CONCLUTIONS</b>Compound danshen dripping pills combined with atorvastatin produces better effects than the drugs used alone in inhibiting vascular smooth muscle cell proliferation in rabbits after abdominal aorta angioplasty possibly due to a decreased expression of MCP-1 as a result of NF-κB inhibition.</p>

The clinical practice of the sickbed management system for student nurses / 现代临床护理

Objective To probe into the clinical effect of the sickbed management system for student nurses.Methods The student nurses at the first department of gynecology from June 2010 to April 2012 were set as the experiment group,in which the sickbed management system was used so that they completed their nursing work at fixed shifts and sickbeds under the nursing teacher’s instructions.The student nurses at the second department of gynecology during the same period were set as the control group,in which the student nurses took different tasks for unfixed sickbeds at different shifts every day.The two groups were compared in terms of the student nurses’knowledge about the patients’diseases and the degree of patients’satisfaction with their nursing work.Result The experiment group was significantly better than the control one in terms of student nurses’knowledge about the patients’diseases and the degree of patients’satisfaction with their nursing work(both P<0.05).Conclusion The sickbed management system for the student nurses may not only enhance nurses’sense of responsibility for their work,but also improve the quality of nursing teaching and patients’ satisfaction with the nursing service.
