Objective: To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school. Methods: From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later. Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention. Results: After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%, χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%, χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%, χ 2=16.05, P <0.05). In addition, after intervention, the total surplus rate of primary school students meals decreased (7.4%, 4.4%, χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%, χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%, χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%, χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%, χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68, P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08, P >0.05). Conclusion The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.

Objective To enhance the standardization of surgical operations,shorten the learning curve,and reduce surgical complications by summarizing common errors and proposing solutions for beginners during pre-study of cavity construction in non-inflatable axillary approach laparoscopic thyroid surgery.Methods A retrospective analysis was made on 210 patients who underwent noninflatable axillary approach luminal thyroid surgery at the Department of Head and Neck Surgery,Zhejiang Provincial People's Hospital,between January 2022 and June 2023.Among them,150 patients were luminalized by the practitioners in the practice group,while 60 patients were luminalized by the practitioners in the skilled group.The occurrence of nine common errors during cavity construction,such as supraclavicular nerve injury and scapulohumeral muscle injury,was assessed and compared between the two groups.Results There was no statistically significant difference in age,gender,tumor diameter,tumor location or pathology type between the two groups(P＞0.05).The staff in the practice group had a significant difference in supraclavicular cutaneous nerve injury(19.33％vs.3.33％),scapulohumeral muscle injury or disarticulation(16.00％vs.0),anterior cervical band of free excess(24.00％vs.3.33％),pectoralis major muscle and supraclavicular fascia injury(16.00％vs.5.00％),external jugular vein and genuine branch injury(8.00％vs.0),excessive freeing of the sternoclavicular joint(7.33％vs.0),and incorrect entry of the sternocleidomastoid muscle gap(8.67％vs.0)were significantly higher in incidence than the employees in the skilled group(P＜0.05).There was no statistically significant difference between employees in the practice group and those in the skilled group in terms of injury to the internal jugular vein and its geniculate branches(4.00％vs.0),and incorrect entry of the anterior cervical strap muscles into the hierarchy(2.00％vs.0)(P＞0.05).Conclusion The incidence of damage to the surrounding tissue was significantly higher in the novice group than in the expert group during endoscopic thyroid surgery for space construction.A solid anatomical foundation and proficient endoscopic surgical technique serve as fundamental prerequisites for achieving a successful space system construction.By summarizing common challenges and providing corresponding solutions encountered during endoscopic thyroid surgery,this study further enhances and refines the learning system for total endoscopic thyroid procedures.

Objective To establish a differential model of phlegm and blood stasis pattern and qi deficiency and blood stasis pattern in stable angina pectoris using radiomics.Methods A total of 91 patients with stable angina pectoris who underwent coronary artery CT angiography in Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from January 2021 to January 2022 were collected,including 47 cases of phlegm and blood stasis pattern and 44 cases of qi deficiency and blood stasis pattern.The patients were divided into train set(64 cases)and test set(27 cases)according to the ratio of 7∶3 by stratified random sampling method.3D-slicer software was used to extract the radiomics features of pericoronary adipose tissue(PCAT)images.Principal component analysis was used to visualize the distribution of radiomics features of pattern of phlegm and blood stasis and pattern of qi deficiency and blood stasis.The least absolute shrinkage and selection operator regression analysis and support vector machine decreasing feature elimination were used for feature selection.The multinomial logistics regression was used for model construction.The receiver operating characteristic(ROC)curve was used to verify the model in the train set and the test set to evaluate the effectiveness of the radiomics features in differentiating phlegm and blood stasis pattern and qi deficiency and blood stasis pattern.Finally,Spearman coefficient was used to analyze the correlation between the differential features and clinical physicochemical data.Results A total of 837 radiomics features were extracted from PCAT images by 3D-slicer software.In the principal component analysis,PC1 and PC2 explained 77.9%and 8.1%of the total variance,respectively,and there was a relatively obvious separation trend between the two pattern groups.After feature screening,7 radiomics features were used to construct the differential model of phlegm and blood stasis pattern and qi deficiency and blood stasis pattern.The area under the ROC curve(AUC)of the differential model was 0.844 in the train set and 0.834 in the test set.Spearman correlation analysis showed that the differential features were significantly correlated with cTnI,neutrophil,triglyceride,total cholesterol,and leukocyte.Conclusion The CT radiomics model based on PCAT has a high discrimination efficiency for stable angina pectoris with phlegm and blood stasis pattern and qi deficiency and blood stasis pattern.
