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.

Objective:To analyze the incidence and risk factors of non-acute symptomatic portal vein thrombosis (PVT) after endoscopic gastric variceal injection (GVI) in the treatment of liver cirrhosis with gastric variceal bleeding (GVB).Methods:66 patients with GVB who were treated with GVI for the first time from July 2017 to October 2019 in Minhang Hospital Affiliated to Fudan University were retrospectively analyzed. The data of gender, age, preoperative Child-Pugh grade, preoperative platelet count, preoperative plasma D-dimer concentration, preoperative splenic length, preoperative portal vein velocity, preoperative splenic vein velocity, preoperative portal vein diameter, preoperative splenic vein diameter, treatment times, total number of injection points, total dose of sclerosing agent and tissue adhesive agent were collected. The patients were divided into PVT group and non-PVT group according to the occurrence of non-acute symptomatic PVT within one year after GVI. Univariate analysis was performed first, and then the factors with P<0.2 were included in the binary logistic regression model to screen the risk factors of PVT after GVI. Results:There were 25 cases (37.88%) in PVT group and 41 cases (62.12%) in non-PVT group. There were significant differences in D-dimer concentration, spleen length, Child-Pugh grade and total dose of sclerosing agent between the two groups ( P<0.05). The D-dimer concentration ( OR=2.319, 95% CI:1.359-3.956), spleen length ( OR=1.044, 95% CI:1.007-1.081) and total dose of sclerosing agent ( OR=1.075, 95% CI:1.004-1.152) were independent risk factors for PVT ( P<0.05). Conclusions:Preoperative D-dimer concentration, spleen length and total dose of sclerosing agent can predict the risk of PVT after GVI. In order to reduce the risk of PVT after GVI, the dose of sclerosing agent should be reduced as much as possible.

Objective The aim of the study was to explore the influencing factors of exercise tolerance in patients with myocardial infarction (MI) after percutaneous coronary intervention (PCI) revascularization in acute state. Methods A total of 112 patients with first MI undergoing PCI revascularization in acute state and completing cardiopulmonary exercise testing (CPET) were enrolled. Exercise capacity was evaluated by peak oxygen consumption percentage (VO2 peak%) in CPET. Patients were divided into normal exercise capacity (NEC) group (n=40) and abnormal (AEC) group (n=72) according to VO2 peak% value. Clinical manifestations, histories of hypertension and diabetes, medications, coronary arterial angiography and echocardiography findings of patients were compared. The onsets of diabetes and blood glucose levels during the period of CPET were evaluated in the MI patients with diabetes. The patients were followed up for major adverse cardiovascular events (MACE) (admission due to chest pain, re?revascularization, re?infarction and all?cause death) within 24 months after PCI. Multivariate logistic regression analyses were conducted to examine influencing factors for exercise tolerance. Results The ratio of diabetes, type C lesions in the AEC group were higher than those in the NEC group (diabetes: 37.5% vs. 17.5%; type C lesions: 69.4% vs. 42.5%, respectively, all P<0.05). The left ventricular ejection fraction (LVEF) in patients in the AEC group was lower than that in the NEC group [(60.6±10.0) % vs. (65.0±8.2) %, P=0.019]. Multivariate logistic regression analyses showed that history of diabetes and history of type C lesions were the independent risk factors for the declined exercise capacity in the MI patients after PCI revascularization ( OR=3.14, 95%CI 1.167-8.362, P=0.023; OR=3.32, 95%CI 1.444-7.621, P<0.01). Among the MI patients with diabetes, the duration of diabetes in the AEC group was significantly longer than that in the NEC group[ (7.7 ± 3.6)years vs. (5.0 ± 2.4)years] and the proportions of subjects reaching target levels of fasting plasma glucose (40.7% vs. 57.1%) and glycosylated hemoglobin A1c(HbA1c) (55.6% vs. 71.4%) in this group were significantly lower than those in the NEC group (all P<0.05). A multivariate logistic regression analysis showed that reaching HbA1c target was an independent predictor of improved exercise tolerance in MI patients with diabetes who received PCI ( OR=2.518, 95%CI 1.395-7.022, P=0.021). No significant differences were observed in incidence of admission due to chest pain, re?revascularization and re?infarction between the two groups within 24 months after PCI between the groups. Conclusions Diabetes and type C lesions are independent risk factors of declined exercise capacity in patients with first myocardial infarction who received revascularization in acute state. Reaching target HbA1c is independent factor of improved exercise capacity in patients with myocardial infarction and diabetes.
