Objective: To analyze the influence of stress and psychological resilience on the dietary behavior of middle school students so as to privide a basis for the development of policies and interventions aimed at improving middle school students dietary behavior. Methods: A total of 8 874 middle school students in Shanghai were surveyed using stratified cluster random sampling method from November 2019 to January 2020. The questionnaire included general information, dietary behavior, Perceived Stress Scale (PSS-10) and Connor-Davidson Resilience Scale (CD-RISC-10). Factor analysis was used to analyze the dietary behavior model. Logistic regression model was used to explore the correlation between stress, psychological resilience and dietary behavior in adolescents. Besides, a structural equation model was established to analyze the mediating effect of psychological resilience on stress and dietary behavior. Results: The total score of psychological resilience among middle school students was (27.99±9.83), and the total score of stress was (25.56±7.06). Factor analysis categorized dietary behavior into two types: the high energy dietary behavior and balanced dietary behavior. High energy dietary behavior exhibited statistically significant differences across genders and schooling stage ( χ 2=41.37, 204.03), while balanced dietary behavior showed statistically significant differences across schooling stage and socioeconomic status ( χ 2=130.23, 96.53) (all P <0.01). Logistic regression analysis showed that adolescents with moderate and high stress levels had an increased risks of high energy dietary behavior ( OR=1.25, 95%CI =1.12-1.39; OR=1.58, 95% CI = 1.39-1.79) and a reduced likelihood of reduced balanced dietary behavior ( OR=0.73, 95%CI =0.65-0.81; OR=0.53, 95%CI =0.47-0.60); adolescents with high levels of psychological resilience had a decreased risk of highenergy dietary behavior ( OR= 0.73 , 95%CI =0.65-0.83), and those with moderate and high resilience levels showed improved balanced dietary behavior ( OR= 1.45 , 95%CI =1.29-1.62; OR=2.50, 95%CI =2.21-2.84) (all P <0.01). The mediating effect of psychological resilience between stress and high energy dietary behavior or balanced dietary behavior accounted for 15.61% and 56.10% of the total effects, respectively. Conclusions Stress and psychological resilience are the influencing factors of dietary behavior in middle school students. Psychological resilience have a partial mediating effect between stress and high energy dietary behavior or balanced dietary behavior.

Objective To analyze the effects of intensive treatment with insulin pump and insulin aspart+insulin glargine 3+1.Methods Fifty patients with type 2 diabetes mellitus(T2DM)in our hospital were randomly divided into insulin aspart+insulin glargine(Asp+Gla)group and insulin pump(IP)group,with 25 cases in each group.Compare the general data,biochemical indicators,serum malondialdehyde(MDA),catalase(CAT),superoxide dismutase(SOD)and adverse reactions between the two groups,and calculate the insulin resistance index(HOMA-IR)and islet β function index(HOMA-β).Results HOMA-β,HDL-C,SOD and CAT in the two groups were higher than those before treatment(P<0.05),while FPG,2 hPG,GA,HOMA-IR,TG,TC,LDL-C and MDA were lower than those before treatment(P<0.05).Compared with Asp+Gla group after treatment,HDL-C,SOD and CAT in IP group increased(P<0.05),while FPG,2 hPG,GA,HOMA-β,HOMA-IR,TG,TC,LDL-C and MDA decreased(P<0.05).Conclusions Intensive treatment with insulin pump can more effectively regulate the level of glucose and lipid metabolism,improve insulin β function and reduce oxidative stress,which is safe and effective.

Objective To investigate the role of delta/notch-like epidermal growth factor-related receptor(DNER)in gastric cancer and its regulatory mechanism.Methods The mRNA and protein levels of DNER in gastric cancer tissues and cells were detected with quantitative real time polymerase chain reaction(qRT-PCR)and Western blot.Gastric cancer cell line SGC7901 with silenced DNER expression was constructed,and cells were treated with mitochondrial dynamin-related protein 1(DRP1)inhibitor Mdivi-1.CCK-8 assay,Transwell assay,and flow cytometry were used to detect cell viability,invasion ability and apoptosis,respectively.Western blot was used to detect DNER protein levels,apoptosis-associated proteins[Cysteinyl aspartate-specific proteinase-3(Caspase-3),Bcl-2 Associated X(Bax)],autophagy associated proteins[microtubule-associated protein 1 light chain 3-Ⅱ/Ⅰ,LC3 Ⅱ/Ⅰ),p62,PTEN induced putative kinase 1(PINK1)and Parkin],and mitochondrial fission and fusion protein[DRP1,mitochondrial fission factor(MFF),mitochondrial fission protein 1(FIS1),Optic Atrophy 1(OPA1),mitofusin 1(MFN1)and MFN2]levels.Results The expression levels of DNER mRNA and protein in gastric cancer tissues were higher than those in adjacent normal tissues(t=-52.485,-46.955),while expression levels of DNER mRNA and protein in gastric cancer cells were higher than those in normal gastric epithelial cells(F=60.551,60.652),and the differences were significant(P＜0.001).Silencing DNER inhibited the proliferation and invasion of SGC7901 cells,induced apoptosis,and increased the expression of apoptosis-related proteins,with significant differences(t=8.026～25.903,all P＜0.05).Silenced DNER increased LC3 Ⅱ/Ⅰ ratio(t=18.086),decreased p62 protein level(t=6.747),promoted the aggregation of PINK1 and Parkin proteins in mitochondria(t=15.630,18.171),inhibited the expression of mitochondrial fusion proteins OPA1,MFN1 and MFN2(t=12.835,8.963,9.732),and promoted the expression of mitochondrial fission proteins DRP1,MFF and FIS1(t=16.034,16.939,15.971),with significant differences(all P＜0.05).Mdivi-1 treatment could counteract the effects of silencing DNER on mitochondrial autophagy,proliferation,invasion and apoptosis of gastric cancer cells.Conclusion DNER can reduce mitochondrial autophagy by inhibiting mitochondrial dynamic imbalance,promote cell proliferation and invasion,and inhibit cell apoptosis,thus promoting the progression of gastric cancer.

Background At present, insufficient support for enterprise health environment and career development may lead to severe depressive emotion among occupational groups. Objective To investigate current state of depressive emotion and the relationship between health literacy and depressive emotion among occupational groups in Shanghai, and to provide evidence for formulating health management measures to alleviate depressive emotion among the occupational population. Methods This cross-sectional survey, using two-stage stratified sampling, was from December 2022 to February 2023, and selected 2548 active workers from 151 enterprises in Shanghai. A total of 2489 valid questionnaires were returned, with a recovery rate of 97.68%. Health literacy, internality health locus of control, and depressive emotion were evaluated by the Health Literacy Questionnaire, the Multidimensional Health Locus of Control Scale-Internality Health Locus of Control, and the Patient Health Questionnaire Depression Scale-9 item (PHQ-9), respectively. R 4.2.2 software was used for statistical analysis, binary logistic regression model was used to analyze the association between health literacy, internality health locus of control, and the risk of depressive emotion, and multiple linear model was used to analyze the correlation between health literacy, internality health locus of control, and PHQ-9 related indicators (total score, affective score, and somatic score). Results A total of 2489 workers aged 18 years and above in Shanghai were included in the analysis, 868 of them reported depressive emotion, and the positive rate of depressive emotion was 34.9%. The total score, affective score, and somatic score of PHQ-9 in M(P₂₅, P₇₅) were 3.00 (0.00, 6.00), 1.00 (0.00, 4.00), and 1.00 (0.00, 3.00), respectively. The results of binary multiple logistic regression analysis showed that after adjusting for selected confounders, no health literacy (OR=1.32, 95%CI: 1.10, 1.60; P=0.004) and low level of internality health locus of control (OR=1.66, 95%CI: 1.35, 2.05; P < 0.001) were associated with an increased risk of reporting depressive emotion. The results of multiple linear model showed that the lack of health literacy and low internality health locus of control were positively correlated with the total score, affective score, and somatic score of PHQ-9. Conclusion Depressive emotion among the working population in Shanghai is prominent, and more than 1/3 of them report depressive emotion. Lower health literacy and internality health locus of control are related to an increased risk of depressive emotion in the study population. Improving occupational health literacy and enhancing internality health locus of control are expected to prevent depressive emotion in occupational groups.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Objective: To investigate the prevalence of adolescents dietary behavior in Shanghai, and to explore emotional influence on dietary behavior. Methods: A total of 7 456 students from 10 junior and 6 senior high schools in Shanghai were selected to participate in the questionnaire survey with the stratified random cluster sampling method. The survey included general information, eating behavior, PHQ-2 and GAD-7. Results: During the past week, the proportion of adolescents in Shanghai reported consumption of sugar sweetened beverages, sweet desserts, frequent fried food and fast food (≥4 times/week) were 13.26%, 16.90%, 6.99 % and 13.01%, respectively. The proportion of students reported consumption of fruits, vegetables, milk and breakfast every day were 56.96%, 73.00%, 65.03% and 76.11%, respectively. There were significant differences by sex and educational stages(both P <0.05). Adolescents with depression or anxiety have a higher incidence of unhealthy eating behaviors than those without depression or anxiety( P <0.01). After adjusting for gender, school, accommodation, grades, pocket money and social class, depression and anxiety increase the risk of various unhealthy eating behaviors in adolescents( P <0.05). Compared with those without anxiety, the risks of sugar sweetened beverages consumption (≥1 time/d) among adolescents with mild and moderate to severe anxiety were 1.42 times (95% CI =1.20-1.67) and 2.51 times (95% CI =2.09-3.01), the risks of insufficient fruits consumption (<1 time/d) were 1.30 times (95% CI =1.16-1.45) and 1.28 times (95% CI =1.11-1.47), the risks of insufficient vegetable consumption (<1 time/d) were 1.35 times (95% CI =1.20-1.52) and 1.41 times(95% CI =1.21-1.65), the risks of insufficient milk consumption (<1 time/d) were 1.29 times (95% CI =1.15-1.44) and 1.20 times(95% CI =1.04-1.39), and the risks of breakfast skipping were 1.75 times (95% CI =1.54-1.99) and 2.97 times (95% CI =2.55-3.46) among adolescents with mild and moderate to severe anxiety. Conclusion The proportion of unhealthy eating behaviors among adolescents in Shanghai is still high. Early education and intervention for students eating behaviors should be carried out, and attention should be paid to the occurrence of adolescents negative emotions, so as to reduce the risk of unhealthy eating behaviors among adolescents through the promotion of mental health.

Objective:To investigate the serum level of low density lipoprotein cholesterol (sdLDL-C) in elderly patients (age≥65 years) with type 2 diabetes mellitus (T2DM) and the its predictive value in evaluatingthe risk of cardiovascular and cerebrovascularevents in elderly patients with T2DM.Methods:In this retrospective study,386 elderly patients with T2DM were collected from December 2014 to December 2016, the averageage was (72.7±5.4) years old, including 269 males and 117 females; 92 of whom had cardiovascular events during follow-up, the averageage was (72.9 ± 5.2) years old, including 65 males and 27 females, and serum sdLDL-C level was detected. Meanwhile, biomarkers such as lipoprotein (a), apolipoprotein B, apolipoprotein AI and hypersensitive c-reactive protein were analyzedin all the patients.Univariate and multivariate factors were used to analyze the relationship between each variable and the occurrence of cardiovascular and cerebrovascular events. The correlation between LDL-C, sdLDL-C of all subjects with age and other lipid indexes were analyzed. ROC curve was used to determine the predictive value of sdLDL-C elevation for cardiovascular and cerebrovascular events in elderly patients with T2DM.Results:The levels of LDL-c, sdLDL-C, non-HDL-C, GLU, HbA1c and ApoB were significantly higher in theCardio-cerebral vascular event group ( t=3.26, 3.46, 2.91, 2.47, 4.03, 3.00, P<0.05). While the levels of apolipoprotein AI was significantly lower than those in theNon-cardio-cerebral vascular event group ( t=-2.39, P<0.05). Cox regression analysis showed that sdLDL-C per 10 mg/dl was independently correlated with the risk of cardiovascular and cerebrovascular events( HR 1.281, 95 %CI 1.225-16.032, P<0.01)after adjusted for age. SdLDL-C was positively correlated with TG, non-HDL-C and ApoB ( r=0.323, 0.588, 0.623, P<0.01) and was negativelycorrelated correlation with age, HDL-C and apolipoprotein AI ( r=-0.363, -0.301, P<0.01), ROC curve analysis showed that sdLDL-C had a strong ability to predict the occurrence of cardiovascular and cerebrovascular events (AUC=0.736, 95 %CI 0.554 9-0.918 2, P=0.003), while HbA1c also had a strong ability to predict the occurrence of cardiovascular and cerebrovascular events(AUC=0.725, 95 %CI 0.524 3-0.927 3, P=0.006). Combined sdLDL-C with HbA1had the strong ability to predict the occurrence of cardiovascular and cerebrovascular events (AUC=0.837, 95 %CI 0.711 4-0.973 5, P=0.001). Conclusions:The elevation of serum sdLDL-C in elderly patients with T2DM wasa significantly independentrisk factorof cardiovascular and cerebrovascular events. Serum sdLDL-C had a higher clinical value than LDL-C, which was expected to be the most effective predictor of lipid profile in riak assessment of cardiovascular and cerebrovascular events in elderly patients with T2DM.

Objective:To investigate the levels and the clinical signficance of matrix metalloproteinase 3 (MMP-3) in different activities of rheumatoid arthritis (RA).Methods:Case-control study. A total of 130 patients [24 cases of male, 106 cases of female, age (52.98±13.24)years, the median age was 51 years] with RA diagnosed in the Department of Rheumatology from the Second Affiliated Hospital of Soochow University, Suzhou Hospital of Traditional Chinese Medicine and Suzhou Ninth People′s Hospital from 2017 to 2018, and 100 healthy controls [28 cases of male, 72 cases of female, age (45.04±11.55) years, the median age was 44 years] from the physical examination center of the Suzhou Ninth People′s Hospital. The basic clinical data was used to determine the MMP-3 on groups of RA patients and healthy controls by immunoturbidimetry. The discriminating validity of MMP-3 in disease was evaluated using receiver operating characteristic (ROC) curve analysis.Results:Compared with that in healthy controls[28.0 (21.7-36.1)ng/mL], the MMP-3 in the low groups [51.8(41.8-73.1)ng/mL] increased dramatically ( Z=2.942, P<0.01). However, there was no significant difference between the MMP-3 in remission patients [28.8 (21.9-38.7)ng/mL] compared with the healthy controls ( Z=1.09, P>0.05). The area under the curve (AUC) of MMP-3 for diagnosis of RA was 0.877. the sensitivity was 73.1%, and the specificity was 93%.The AUC of MMP-3 diagnosis of low groups was 0.906, the sensitivity was 77.8%, and the specificity was 88%. In addition, the MMP-3 level was correlated with CRP and ESR ( r=0.242, r=0.243), and it was significantly correlated with DAS 28 ( r=0.361). Conclusions:It was indicated that the level of MMP-3 increased with the severity of rheumatoid arthritis. And the clinically low level of MMP-3 in RA patients could be used to indicate the remission condition. Meanwhile, the serum MMP-3 was closely related to DAS28.

Objective To analyze the efficacy and safety of CyberKnife combined with temozolomide (TMZ) in treatment of brain metastasis of non-small cell lung cancer (NSCLC). Methods From March 2013 to March 2016, 62 NSCLC patients with brain metastases in department of oncology of the 187th Hospital of PLA were divided into two groups according to the random number table method, the CyberKnife combined with TMZ group (CyberKnife + TMZ group, 31 cases) and simple CyberKnife group (CyberKnife group, 31 cases). Hypofractionated radiation of CyberKnife was given 18-36 Gy in 1-5 fractions of 5-25 Gy. CyberKnife+ TMZ group was given temozolomide 150 mg·m-2·d-1 for 5 days in first cycle, then every 28 days they received temozolomide therapy from the second to the sixth cycles: 200 mg·m-2·d-1 for 5 days. The clinical symptom remission rate after the treatment of CyberKnife in one week, the effective rate after CyberKnife in 3 months, the median intracranial progression-free survival time, overall survival, and the incidences of adverse reaction were comparatively analyzed. Results The clinical symptom remission rates of CyberKnife+TMZ group and CyberKnife group after the treatment of CyberKnife in one week were 93.6 ％ (29/31) and 96.8 ％ (30/31). There was no significant difference in the clinical symptom remission rates (χ2= 1.207, P=0.547). The effective rates of the two groups after CyberKnife in 3 months were 93.6 ％ (29/31) and 90.3 ％(28/31). There was no significant difference in the effective rates (χ2 = 0.695, P= 0.706). The median intracranial progression-free survival time in CyberKnife + TMZ group (14.0 months) was significantly higher than that in the CyberKnife group (9 months) (χ2=8.977, P=0.003), and the median overall survival time in CyberKnife + TMZ group (15.0 months) was also significantly higher than that in the CyberKnife group (12.0 months) (χ2 = 5.190, P= 0.023). There was no significant difference in the adverse reaction of the central nervous system between the two groups (χ2=0.746, P=0.689), but the adverse reactions of the digestive system (χ2 = 6.062, P= 0.014) and the hematologic system (χ2 = 6.613, P= 0.010) in CyberKnife + TMZ group were significantly higher than those in the CyberKnife group. Systemic adverse reactions of the two groups were tolerated by most patients. Conclusions CyberKnife combined with TMZ is a feasible therapeutic option for NSCLC patients with brain metastases. This therapy can improve the median survival time to cerebral progression of the disease and the median overall survival time.
