ABSTRACT
Food processing and cooking is very practical, and requires students to master certain knowledge and operational skills of nutrition. Therefore, we introduced the experience teaching design, con-crete experiment, reflective observation, abstract generalization and application, focused on practice-appli-cation-further practice in the teaching process, readjusted and set practical objectives, contents, teaching methods, evaluation, and used questionnaire and interview method to evaluate the teaching effect, which enriched the teaching content of the course and improved the effectiveness of students'!practice learning.
ABSTRACT
Objective To investigate the malnutrition status among the elderly in age care institutions in Shanghai suburb and analyze its potential influential factors.Methods The MiniNutritional Assessment (MNA) was adopted to evaluate the nutritional status of the 190 elderly people in age care institutions.The dietary supply by the institution canteen and the quantity of residual food left by the malnourished elderly people were weighted.Results In the age care institutions,the malnutrition rate reached 23.7％,47.9％ of the elderly people were at the risk of malnutrition,and only 28.4％ of the elderly people were well nourished.Logistic regression analysis showed that the major influential factors for malnutrition in the elderly people were food intake ability,mobile capability,chewing and swallowing ability,ageing and mental Illness.The malnourished elderly people had the most residual meat and vegetables,and insufficiency of nutrient intake was the main cause for the malnutrition in the elderly people.Conclusions The elderly people in age care institutions in Shanghai suburb have the higher risk of malnutrition.The malnutrition occurs under influence of many factors,of which some are unavoidable,however,some factors like dietary factors can be changed to improve the nutritional status of the elderly people in age care institutions.
ABSTRACT
To explore the discrimination model of subhealth with statistical method of partial least squares (PLS).
ABSTRACT
OBJECTIVE: To investigate the effects of Guizhi Decoction, Chaihu Guizhi Decoction, Xiaochaihu Decoction and camostat on rat spontaneous chronic pancreatitis and the pathological relationships between formulas and syndromes. METHODS: Fifty-seven male WBN/Kob rats at age of 4 weeks were divided into five groups: untreated group (n=18), Guizhi Decoction-treated group (n=9), Chaihu Guizhi Decoction-treated group (n=9), Xiaochaihu Decoction-treated group (n=9) and camostat-treated group (n=12). The rats in each group were fed with corresponding drugs for 12 weeks. The pancreatic wet weight and histopathological changes of pancreatic tissue were observed every four weeks. Meanwhile, the expression level of pancreatitis-associated protein (PAP) in pancreas was detected by RT-PCR technique and immunohistochemical method. RESULTS: In the untreated group, the histopathological changes in pancreas were observed in rats at 12-week age, while such changes were absent in the Guizhi Decoction-treated group. The histopathological changes in pancreas were quite remarkable in rats at 16-week age in both the Xiaochaihu Decoction-treated and the camostat-treated groups. The expression level of PAP mRNA was lower in the Guizhi Decoction-treated group than those in the other groups. The PAP expressions were absent in rats at 12-week age in the Guizhi Decoction-treated and the Chaihu Guizhi Decocion-treated groups. CONCLUSION: Guizhi Decoction, Chaihu Guizhi Decoction, Xiaochaihu Decoction and camostat are all beneficial to prevention and cure of chronic pancreatitis, and Guizhi Decoction is the most effective one. It is speculated that Taiyang exterior syndrome may be the pathogenesis of basic syndrome may be the pathogenesis of basic syndrome of spontaneous chronic pancreatitis, and the expression of PAP may be its pathological basis.
