Objective To explore the features of functional networks about recognizing dynamically positive expression with using magnetoencephalography (MEG) technology and the paradigm of expressional experiment, and further to examine its neurological basis. Methods Twelve depressed patients and twelve age,education-matched healthy controls participated to recognize the dynamically positive expression in the MEG scans. Results In comparison with the healthy,the abnormally activities regions in depressed patients during different time periods were separately as follow;decreased activation in the right inferior parietal lobule(t = 3.94),the right su-pramarginal gyms(t = 3.59),the bilateral posterior cingulated(t = 5. 04, t = 4. 85) ,the bilateral precuneus(t = 3.84) ,the left cuneus(t = 3.58) and increased activation in the bilateral hippocampus(t = 2. 13, t = 2.56) ,the left amygdale(t = 2.41), the bilateral uncus gyrus(t = 2.33, t = 2.44) , the right anterior cingulated (t = 2. 15) , the left fusiform gyms (t = 3. 33) (P < 0. 05, unconnected). Conclusion The results indicate, compared with healthy controls,abnormal brain activities as the weakened function of the medial temporal cortex,parietal lobe and the enhanced function of limbic system were distributed extensively in depressed patients during recognizing dynamically positive expression. These abnormalities may prompt the dynamic characteristics of the magnetic source imaging about recognizing dynamically positive expression,and further reveals the mechanisms of emotional symptoms in depression.

Objective To investigate the food intake of one meal of the hotel customers and evaluate it rationality ,then provide dietary suggestions .Methods Six hundreds hotel customers were investigated in 2 four‐star hotel and 2 five‐star hotel of Nanjing , who were selected with a stratified sampling method .Their 5 days diet were investigated and then the dietary intake ,the percentage of energy from protein ,fat and carbohydrate and the percentage of protein resource were calculated based on the food composition table .Results It was shown that the daily energy intake of one meal was appropriate among the surveyed hotel customers ,and the energy proportion from 3 major nutrients were not reasonable ,and the energy proportion from fat were higher than other 2 major nutrients ;the proportion from the source of good proteins was reasonable ,but the intake of protein was too much;the customers fell short on their daily serving of grains ,eggs ,beans and milk products and the intake of cooking oil and salt was excessive in diets . Their intake of fat ,protein ,retinol equivalent ,niacin ,vitamin E ,sodium and iron were too much .Instead ,they ate less ascorbic acid;only the intake of energy ,riboflavin and thiamine were appropriate .Conclusion The one meal dietary structure of hotel customers is not appropriate ,while nutrition collocation is not reasonable .It is necessary to promote nutrition and health education and some intervention measures must be taken .
