Objective:
To explore the screen related sedentary behavior among senior primary school students in Beijing and to analyze the influence of psychosocial determinants and nutrition related knowledge on the behavior.
Methods:
In January 2020, a total of 1 316 students in grade 4-6 from two primary schools in Beijing were selected. Information on video viewing (watching TV or playing video games), self efficacy, habit strength, nutrition related knowledge, outcome expectation and the capacity to persist toward goal attainment were collected through questionnaires. Disordered multi classification Logistic regression and random forest algorithm were used to analyze the influencing factors.
Results:
The frequency of screen related sedentary was 5.0 (3.0, 10.5) times/week, and the duration was 37.5(9.6, 97.5) min/d in senior elementary school children. The results of disordered multi classification Logistic regression showed that the capacity to persist toward goal attainment, nutrition related knowledge, habit strength, self efficacy and gender positively correlated with the frequency of screen related sedentary ( OR =1.6, 1.7, 4.9, 4.2, 1.5 ), while the nutrition related knowledge, habit strength, self efficacy, outcome expectations, grade and gender positively correlated with screen time ( OR =1.7, 5.6, 5.7, 1.6, 1.6, 1.7)( P <0.05). Random forest regression tree model showed that the top four influencing factors on screen related sedentary frequency were self efficacy, the capacity to persist toward goal attainment, habit strength and nutrition related knowledge and the top four influencing factors on screen time were self efficacy, outcome expectation, nutrition related knowledge, habit strength.
Conclusion
Screen related sedentary behavior is prevalent among senior primary school students in Beijing. Health education should be strengthened regarding influencing factors of screen related sedentary behavior.

Objective:
The association of self efficacy, habit strength, goal intention and outcome expectation with the consumption of snack in senior primary school students were investigated, providing evidence for the application of psychosocial determinants based on Social Cognitive Theory in children s nutrition education.
Methods:
A total of 1 353 students, 10-12 years old, participated in this study. Participants completed questionnaires for assessing self efficacy, habit strength, goal intention, outcome expectation and snack consumption in January 2020.
Results:
Average times of snack consumption among primary school students were 5.0 (3.0, 8.5) times per week, and the snack intake were 4.0(0.9, 22.9)g/d. The outcome expectation score was -1.0(-2.0, -1.0 ) points, while the score of children s snack related selfefficacy was (4.3±0.9) points, habit strength score 1.0(1.0, 3.0) points, and the goal intention (4.2±1.2) points. Students with higher snack intake showed lower scores in outcome expectation, self efficacy and goal intention( t=-9.0, 6.8, 5.2, P <0.01). Logistic regression showed negative association between outcome expectation and self efficacy factors with snacking behavior( OR =0.7, 0.8, respectively), as well as positive association between habit strength and snacking behaviors( OR=1.3, P <0.05).
Conclusion
The evidence indicated that self efficacy, habit strength, goal intention and outcome expectation are associated with child s snack consumption, and can be used as theoretical foundation for child snack consumption education.

OBJECTIVETo investigate the characteristics and dynamic changes of serum neutralizing antibody response in patients with primary infection of dengue virus type 1 (DENV-1).
METHODSSerum samples were obtained from the same patients with primary infection of DENV-1 within 2 weeks after symptom onset in 2006 and in 2010. A group-specific DENV NS1 capture ELISA-based micro-neutralizing test (ELISA-MNT) capable of detecting neutralizing antibodies against all the 4 serotypes of DENV was used to test the neutralizing antibody titers against DENV in the serum samples. The neutralizing antibody titers against a standard strain and 2 clinically isolated strains of DENV-1 were detected in serum samples collected in 2010.
RESULTSCross-reactive neutralizing antibody response against all the 4 serotypes of DENV was found in both of the serum samples collected in 2006 and 2010, but the samples collected in 2006 showed stronger cross-reactive neutralizing antibody responses. The neutralizing antibody against DENV-2, rather than the anticipated DENV-1 antibody, had the highest titer in the samples collected in 2006, whereas the antibody against homologous DENV-1 had the highest titer in the samples obtained in 2010. The neutralizing antibody titers against the homologous DENV-1 was significantly higher in samples collected in 2010 (U=86.500, P=0.000), which also demonstrated significantly different neutralizing antibody titers against the 3 different strains of DENV-1 (Χ(2)=12.123, P=0.002).
CONCLUSIONThe production of cross-reactive neutralizing antibodies between the 4 serotypes of DENV is a characteristic of DENV infection, particularly during early infection, but only the homologous neutralizing antibody increases obviously over time. The titers of the neutralizing antibodies against different strains, even of the same serotype, may differ distinctly.

Objective:To evaluate the effect of definitive radiotherapy with different doses on overall survival (OS) and identify the prognostic factors of patients with non-metastatic esophageal squamous cell carcinoma (ESCC).Methods:Clinical data of 2 344 ESCC patients treated with definitive radiotherapy (RT) alone or chemoradiotherapy from 2002 to 2016 in 10 hospitals were collected and analyzed retrospectively. After the propensity score matching (PSM)(1 to 2 ratio), all patients were divided into the low-dose group (equivalent dose in 2 Gy fractions, EQD 2Gy<60 Gy; n=303) and high-dose group (EQD 2Gy≥60 Gy; n=606) based on the dose of radiation. Survival analysis was conducted by Kaplan- Meier method. Multivariate prognostic analysis was performed by Cox′s regression model. Results:The median follow-up time was 59.6 months. After the PSM, the 1-, 3- and 5-year overall survival (OS) rate was 66.5%, 34.7%, 27.2% in the low-dose group, 72.9%, 41.7% and 34.7% in the high-dose group, respectively ( P=0.018). The 1-, 3-and 5-year progression-free survival rate was 52.2%, 27.2%, 23.1% in the low-dose group, 58.3%, 38.1% and 33.9% in the high-dose group, respectively ( P=0.001). The outcomes of univariate analysis indicated that cervical/upper esophagus location, early (stage Ⅱ) AJCC clinical stage, node negative status, tumor length ≤5 cm, receiving intensity-modulated radiation therapy (IMRT), receiving concurrent chemotherapy and EQD 2Gy≥60 Gy were closely associated with better OS (all P<0.05). Multivariable analysis demonstrated that tumor location, regional lymph node metastasis, concurrent chemotherapy and EQD 2Gy were the independent prognostic factors for OS (all P<0.05). Conclusion:Three-dimensional conformal or IMRT with EQD 2Gy≥60 Gy yields favorable survival outcomes for patients with locally advanced ESCC.

Objective To investigate the effects of formononetin (FMN) on cognitive behavior and inflammation in aging rats with chronic unpredictable mild stress (CUMS). Methods SD rats aged about 70 weeks were divided into healthy control group, CUMS model group, CUMS combined with 10 mg/kg FMN group, CUMS combined with 20 mg/kg FMN group and CUMS combined with 1.8 mg/kg fluoxetine hydrochloride (Flu) group. Except for healthy control group, other groups were stimulated with CUMS and administered drugs for 28 days. Sugar water preference, forced swimming experiment and open field experiment were used to observe the emotional behavior of rats in each group. HE staining was used to observe the pathological injury degree of brain equine area. The contents of 5-hydroxytryptamine (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) were detected by the kit. The apoptosis was tested by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) in the brain tissue. The levels of tumor necrosis factor α (TNF-α), inducible nitric oxide synthase (iNOS) and interleukin 6 (IL-6) in peripheral blood were measured by ELISA. Western blot analysis was used to detect Bcl2, Bcl2 associated X protein (BAX), cleaved caspase-9, cleaved caspase-3, Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and phosphorylated nuclear factor κB p65 (p-NF-κB p65) in brain tissues. Results Compared with CUMS model group, sugar water consumption, open field activity time, open field travel distance and swimming activity time significantly increased in the CUMS combined with 20 mg/kg FMN group and the CUMS combined with 1.8 mg/kg Flu group. The number of new outarm entry increased significantly, while the number of initial arm entry and other arm entry decreased significantly. The pathological damage of brain equine area was alleviated, and the contents of 5-HT and 5-HIAA were significantly increased. The ratio of BAX/Bcl2 and the expression of cleaved caspase-9 and cleaved caspase-3 protein as well as the number of apoptotic cells were significantly decreased. The contents of TNF-α, iNOS and IL-6 were significantly decreased. The protein levels of TLR4, MyD88 and p-NF-κB p65 were significantly decreased. Conclusion FMN can inhibit the release of inflammatory factors by blocking NF-κB pathway and improve cognitive and behavioral ability of CUMS aged rats.
