BACKGROUND:Metabolic syndrome greatly harms the human body, and is affected by many factors. Through constructing diet-induced animal models, we can better analyze the relationship between nutritional factor and metabolic syndrome, and provide reliable references for the clinical treatment of this disorder. OBJECTIVE:To construct obese mouse models with high-fat diet feeding and discuss the relationship between nutritional factor and metabolic syndrome. METHODS:Thirty mice were selected and randomly divided into model group (n=20) and control group (n=10), and were fed with high-fat and normal animal feeds for 10 consecutive weeks. RESULTS AND CONCLUSION:Compared with the control group, after 1 week of feeding with high-fat animal feeds, body weight of mice in the model group raised, and differences gradualy increased with the feeding time increased. After 8 weeks of feeding, body mass index of mice in the model group significantly raised (P < 0.05). After 4 weeks of feeding, fasting venous blood glucose level of mice in the model group significantly raised, and showed a gradual rise trend with feeding time. After 5 weeks of feeding, fasting insulin level of mice in the model group also began to rise. The oral glucose tolerance test showed that mice in the model group showed a gradual downward trend of glucose tolerance with feeding time. After 8 weeks of feeding, serum levels of total cholesterol and high density lipoprotein cholesterol in the model group significantly raised (P < 0.05). After 10 weeks of feeding, serum levels of triacylglycerol, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol in the model group raised (P< 0.05). The results demonstrate that obese mouse models were successfuly constructed with high-fat diet feeding, which can simulate the natural progression of metabolic syndrome in human, moreover, the nutritional factor is closely related to metabolic syndrome.

Objective To evaluate the effects of clinical pathway combined with transitional care implemented by specialty nurses on patients with coronary heart disease after PCI (percutaneous coronary intervention) therapy. Methods Totally 124 patients after PCI were divided into the experimental group and the control group with random digit table. Patients in the control group received routine education and follow- up during hospitalization and discharge period. The experimental group received clinical pathway combined with transitional care implemented by specialty nurses based on routine education. The level of patients′knowledge, attitude, practice and risk factors were compared between the two groups 6 and 12 months after discharge. Results There were 55 patients in each group completed the research ultimately. The Coronary Heart Disease Knowledge Questionnaire in the experimental group scored (57.61 ±8.77), (81.27±6.88) and (88.47±6.10),while the control group scored (59.71±7.32),(68.61±7.12) and (76.85±7.70), after repeated measurement analysis of variance, F=74.71, 14.52, P<0.01. The scores of General Self- Efficacy Scale (GSES) and Coronary Artery Disease Self- Efficacy Scale (CSMS) between two groups at three time points showed statistical significance, F=5.40, 14.52, P<0.05 or 0.01. The risk factors of coronary heart disease such as total cholesterol, triacylglycerol, hemoglobin A1c, body mass index, systolic pressure and diastolic pressure were statistically different between two groups except for high density lipoprotein cholesterol and low density lipoprotein cholesterol, F=5.82, 20.32, 4.14, 4.15, 4.99, 7.15, P<0.05 or 0.01. Conclusions Clinical pathway combined with transitional care implemented by specialty nurses can improve the knowledge-attitude- practice level of patients, help to control the risk factors of coronary heart disease. It is an effective heart rehabilitation model for patients after PCI.

Objective To analyze the expression level of HSP72 and HSP73,the subtypes of HSP70, in peripheral blood lymphocytes from lung carcinoma patients on both basic and heat injury conditions,and to explore the significance of HSP70 in the development of lung cancer.Methods Lung cancer patients were selected'as experimental group,and the health people with similar age,gender,vocational history and inhabi- tation to the experimental group were chosen as control group.The blood lymphocytes from both groups were isolated,cultured and treated with heat injury at either 37℃or 42℃.The expressions of HSP72 and HSP73 in the isolated lymphocytes were determined by Flow Cytometry.Results There were much higher expressions of HSP72 and HSP73 in control group(21.97?2.40 vs 12.77?0.66)than which in experimental group(HSP72 19.0?2.12 vs HSP73 11.74?0.68,P
