RESUMEN
Nursing students in junior college have less class time and weaker foundation com-pared with nursing undergraduates, therefore it is more difficult for them to learn pathphysiology. In order to improve the teaching effect, we adopt the following strategies in pathophysiology teaching:①Guiding clinical nursing practice combining with specific situation in order to give students a deep understanding of pathophysiology knowledge and its significance. ②Urging students to review relevant basic knowledge before class and teacher to briefly introduce the basic knowledge before initiating class in order to reinforce the knowledge. ③Examples of daily life should be combined to make the abstract theory knowledge vivid. Teaching should revolve around the main line and key points should be highlighted. ④Dividing pathophysiology course into three units, and summary must be executed at the end of each unit.
RESUMEN
Most content of pathophysiology is built by black-box method.Pathophysiology learning is a process from black-box to grey box and white-box.Therefore,black-box teaching method is a good way to train students efficiently and rapidly.It fits pathophysiology education wel1.During teaching of pathophysilogical theory and experimental classes,we should carefully design various black-boxes,and introduce students try to resolve the black-box problems,so as to interest students in pathophysiology and train them the capability to analyse and resolve problems.
RESUMEN
Objective To investigate the changes of the cytokines on the aortas of atherosclerosis (AS) rats. Methods Zymosan-liquid medical paraffin suspension (contain Zymosan 20 mg/kg) was injected intra- peritoneally once a week for 10 times and given intraperitoneal injections of ovalbumin, 2.5 mg/kg, once a week for 7 times after initial subcutaneous sensitization. All animals were fed cholesterol-rich diet to induce AS. Electron microscopy was used to observe the foam cells, and RayBio Rat Cytokine Antibody Array 1.1 was employed to detect the cytokines in the aorta wall. Results Electron microscopy showed all models had monocytes migration from lumen to subendothelium in the aorta and formed to foam cell for phagocytosis lipid, indicating typical characteristic of AS in the rats. Most pro-inflammatory cytokines were increased except Fractalkine and IL-6, but anti-inflammatory cytokines were all slightly decreased. Conclusion Inflammation and immune can induce the formation of foam cells. The balance of pro-inflammatory cytokines and anti-inflammatory cytokines is broken is the important reasons of atherogenesis。
