OBJECTIVE To discuss the management methods of sputum sample retained clinically based on the praxiology,and aim at improving the quality of the sputum retained. METHODS Through investigating the quality of sputum sample retained routinely from the department of internal medicine in a general hospital at the duration from Sep 2004 to Feb 2005,the intervention effect was evaluated by carrying out the measure of praxiology intervention. RESULTS The qualification rate was 23.7% for the sputum sample retained routinely from the hospital at the duration from Sep 2004 to Feb 2005,after carrying out the measure of praxiology intervention,the qualification rate was 30.1% at the duration from Apr 2005 to Aug 2005.Statistic data showed that there was no significant difference. CONCLUSIONS The quality of the sputum sample retained routinely is poor,and the measure of praxiology intervention failed to improve the quality of the sputum sample.Microscopy is the most important measure to ensure the quality of the sputum sample for the cytology test before cultivating the sample,and should be a routine test in hospital.The study on praxiology intervention will be further carried out in the future.

Objective: To investigate the lunch supply in primary and middle school dining rooms in Ningbo City, so as to provide the scientific evidence for guiding rational dietary supply and improving student health. Methods: A primary school and a junior high school were randomly sampled from each of 10 counties (districts) in Ningbo City. Food receipt and balance, dinner supply and number of students with meals were collected from school dining rooms with questionnaires formulated by Zhejiang Provincial Center for Disease Control and Prevention, and all foods in school dining rooms provided by enterprises were sorted and recorded. Daily mean lunch food, energy and nutrient supply was calculated per student, and evaluated with the Student Electronic Nutritionist platform, the 2013 revision of Chinese Dietary Reference Intakes and the national criteria of Nutrition Guidelines of Student Meals (WS/T 554-2017). Results: Six urban primary schools, six urban junior high schools, four rural primary schools and four rural junior high schools were enrolled, and there were two schools with meals provided by enterprises and eighteen schools with meals provided by their dining rooms. Appropriate supply of cereals and potatoes, excessive supply of livestock and poultry meat, vegetable oil and salt, and low supply of fruits, eggs, milk and soybean and nuts were found in primary and junior high school, and notably, milk and fruits were not provided by any rural junior high schools. Excessive energy supply was found in primary schools (excessive energy supply in rural primary schools and appropriate in urban primary schools), and appropriate energy supply was seen in junior high schools. High energy ratios of protein and fat, low energy ratio of carbohydrate, low supply of diatery fiber, vitamin A and calcium, appropriate supply of vitamin B1, B2 and C, and sufficient supply of iron and zinc were found in primary and junior high school. Conclusion Unreasonable dietary structure, excessive energy supply and nutrient imbalance are found in lunch supply by primary and junior high schools in Ningbo City.
