Objective To understand intake frequency of sugar-sweetened beverages (SSBs) and the consumption habit among primary and secondary students. To explore the relationship of SSBs cognition and behavior, and to provide a basis for reducing students' intake of SSBs. Methods A multi-stage sampling process was employed to select subjects from primary and middle school in Shenzhen. Network questionnaire survey was conducted to collecting information in September and October, 2021. Spearman rank correlations was used to analyze relationships of various types of SSBs consumption frequency. Multivariable linear regression model was used to examine the relationship between SSBs cognition score and consumption frequency score. Hierarchical analysis to explore the interactions. Results A total of 16 840 primary and secondary students aged 6 to 18 years old were included. The prevalence of SSBs consumption at least 3 time/week was 58.9%, the grades 1-3, 4-6 and middle school students were 52.3%, 60.3% and 67.6%. Parents (73.3%) were the main buyers of SSBs, convenience stores (73.7%) were the main places and delicious (77.2%) was the major cause of choices. There was a positive correlation between the intake frequency of different types of SSBs (P < 0.001). The results of multivariate linear regression showed that the higher the cognition was, the lower the intake frequency of SSBs was (β = 0.179, 95%CI: 0.155-0.204). There was a multiplicative interaction between the cognitive score of SSBs and the educational level of parents (P < 0.00l). Conclusion The intake frequency of SSBs was high among primary and middle school students in Shenzhen, and the cognitive level of SSBs was related to the intake frequency and the educational level of parents.

Objective To study the interaction between snoring and hyperuricemia on metabolic syndrome (MetS) in children and adolescents, putting forward targeted countermeasures to prevent and control MetS in the specific subpopulation. Methods Demography data, snoring, anthropometric measurements, and biochemical indicators were obtained from children and adolescents aged 7 - 17 years old who participated in the evaluation and monitoring on school - based nutrition and growth in Shenzhen. Logistic regression model was conducted to evaluate the association between snoring and hyperuricemia on MetS, and an additive model to evaluate the impact of their interaction on MetS. Results The median age of 4 466 participants was 12. 16 years, and 2 454 (54. 9% ) were boys. The detection rates of MetS, snoring, and hyperuricemia accounted for 3. 2%, 29. 3%, and 33. 4% of the total population, respectively. The frequency of snoring < 1 time/week, 1-2 times/week, and ^ 3 times/week were positively correlated with MetS disease and showed a gradually increasing trend (P trend <0. 001). Snoring (OR =2.085, 95% CI- 1.462 -2.902) and hyperuricemia (OR = 4. 741, 95% CI- 3. 144 -7. 148) were both associated with MetS. In addition, there was no multiplicative interaction between snoring frequency, snoring, and high uric acid on MetS, but snoring and high uric acid had an additive interaction on MetS [ relative excess risk due to interaction = 3. 801 (0. 060 - 7. 542), attributable proportion of interaction = 0. 418 (0. 154 - 0. 683), synergy index = 1. 887 (1. 101 - 3. 234) ] . Conclusion Snoring and hyperuricemia are both risk factors for MetS. There is a synergistic effect between snoring and hyperuricemia on the risk of MetS. Therefore, it is necessary to actively control weight, maintain positive airway pressure ventilation, orthodontic treatment, limit fried foods, meat, seafood, and increase vegetable intake to improve snoring and uric acid levels in children and adolescents, in order to achieve prevention and management of MetS.

Objective: To investigate the expression of MIF on the gastric adenocarcinoma, evaluate the relation between the MIF expression and tumor differentiation, lymph node metastasis and other clinical patho-features., Methods: 120 gastric adenocarcinoma cancer tissues, 40 tissues besides cancer and 40 common mucosa tissues specimens are collected. Detect the expression of MIF with immunohistochemistry method (Streptavidin-Peroxidase)., Results: Positive rate of MIF expression in gastric cancer is 80.8% (97/120). Those in poorly differentiated, moderately differentiated and well-differentiated gastric adenocarcinoma are 97.5% (39/40), 82.5% (33/40), 62.5% (25/40), analytical factor of Spearman rank correlation r(s) is 0.458 (χ(2) = 27.046, P < 0.001). Positive rate of MIF expression in tissues besides cancer is 40% (16/40) and that in normal gastric mucosa is 7.5% (3/40). Positive rate of MIF expression in gastric adenocarcinoma without lymph node metastasis is 40% (22/55) and the rate with lymph node metastasis is 67% (44/65)., Conclusions: There is overexpression of MIF in the gastric adenocarcinoma. Expression of MIF in different differentiated cancer is different. Expression in poorly differentiated is higher than that in moderately differentiated and well-differentiated cancer. The level of expression of MIF malignancy has positive correlation with malignancy degree of gastric adenocarcinoma. MIF expression has nothing to do with age, gender, tumor sizes or location.
