RESUMEN
To assess the independent and joint associations between cardiorespiratory fitness (CRF), screen time and mental health among Chinese school-aged children, a cross-sectional study was conducted in 3 primary schools in Wuhan city, China. Children self-reported ST, and their height, weight and CRF were measured. Mental health (anxiety, depressive symptom, and self-esteem) was assessed by self-administered questionnaires. A total of 805 children aged 9.1â ±â 0.6 years participated in this study. High ST was associated with significantly increased risk for anxiety and low self-esteem, while high CRF was associated with a decreased risk of low self-esteem. In the joint model, children with low ST and high CRF showed the lowest risk for anxiety (OR: 0.42, 95%CI: 0.20-0.89) and low self-esteem (OR:0.44, 95%CI: 0.24-0.82). High ST and low CRF were negatively associated with mental health in Chinese schoolchildren. Health care and interventions on limiting ST and improving CRF level are warranted to promote the mental health in this population.

Low activity and poor product selectivity of CO2 reduction have seriously hampered its further practical application. Introducing p-block atoms to the catalyst is regarded as a promising strategy due to the versatility of p orbitals and diversity of p-block elements. Here, we systematically studied the influence of p-block atom X (X = C, N, O, S, and Se) on CO2 catalytic properties on a Sn(200) surface by first-principles calculation. Our work shows that all the p-block atoms are relative stable with Ef in the range of -5.11 to -3.59 eV. Further calculation demonstrates that the diversity of the p-block atoms results in unique CO2 electrocatalytic activity and product selectivity. Interestingly, the p-block C atom shows bi-functional activity to form two-electron products HCOOH and CO, with the corresponding energy barriers remarkably low at about 0.19 eV and 0.28 eV. In particular, the p-block S(Se) atom appears to have striking HCOOH selectivity, with the energy barrier to form HCOOH only a quarter of that to form the CO product. This unusual behavior is mainly attributed to the adsorption strength and frontier orbital interaction between the p-block atom and intermediates. These findings can effectively provide a valuable insight into the design of highly efficient CO2 electrocatalyst.
RESUMEN
The study aimed to investigate the individual and combined association of health-risk behaviors with mental health among Chinese children. A cross-sectional study was conducted in Wuhan, China, from May to June 2018. Participants self-reported the information on physical activity (PA), screen time (ST), fruit and vegetable (FV) intake, and sleep duration. Mental health, including depression, social anxiety and self-esteem, was assessed using standard questionnaires. A total of 1296 children (704 males and 592 females) aged 9.2 ± 0.4 years were included in the present study. The prevalence of low PA, high ST, low FV intake, and inadequate sleep duration was 45.6%, 18.0%, 69.7%, and 64.7%, respectively. Overall, significant associations were found between individual health-risk behavior and increased risks of mental health. Furthermore, children with three or four health-risk behaviors showed significantly increased risks of anxiety (OR: 3.18, 95%CI: 1.63-6.21), depression (OR: 4.55, 95%CI: 2.28-9.09) and low self-esteem (OR: 3.59, 95%CI: 2.20-5.88) compared with those without health-risk behavior. Results of this study revealed a high prevalence of health-risk behaviors among Chinese children. Furthermore, the clustering of health-risk behavior was associated with significantly increased risks of mental health in this population. Considering these findings, it is important to perform early interventions to reduce children's health-risk behavior and prevent mental health problems.

BACKGROUND: The CXC chemokines belong to a unique family of cytokines that participates in the progression and development of many malignant tumors. Evidence for the relationship between chemokine (C-X-C motif) receptor 2 (CXCR2) C1208T polymorphism and susceptibility to cancer remains inconsistent. METHODS: Odds ratios (ORs), 95% confidence intervals (CIs), and combined analysis were used to investigate the effect of CXCR2 variation on cancer risk. Gene Set Enrichment Analysis (GSEA) and enzyme-linked immunosorbent assay (ELISA) were also used to evaluate the expression of CXCR2 in prostate cancer (PCA). RESULTS: Across 11 case-control studies, 4,909 cases and 5,884 controls were involved in the current analysis. Individuals with a TT genotype were associated with increased risk of digestive cancer, compared to those with a TC+CC genotype (OR = 1.16, 95%CI = 1.02-1.31, P = 0.025). Individuals carrying the TT genotype had a 39% higher risk of urinary cancer than those carrying CC genotype (OR = 1.39, 95%CI = 1.04-1.87, P = 0.025). Individuals with a TT genotype showed a 56% augmented breast cancer risk, compared to those with a CC genotype (OR = 1.56, 95%CI = 1.03-2.35, P = 0.034). It was found that CXCR2 expression was downregulated in PCA. Compared with PCA subjects carrying the CC genotype, the expression of CXCR2 was decreased in patients with the TT genotype. CONCLUSIONS: The CXCR2 C1208T variation was associated with elevated risk of urinary, breast, and digestive cancer. However, the C1208T polymorphism was correlated with attenuated risk of lung cancer.

BACKGROUND: Adverse childhood experiences (ACEs) have been linked to long-term health outcomes, while the impact of such experience has not been investigated among Zambian youth. This study examined the associations of ACEs with individual and clusters of health risk behavior among college students in Zambia. METHOD: A total of 624 college students participated in this cross-sectional study. A self-administered questionnaire was used to collect information on their ACEs and health risk behaviors. RESULTS: There were 58.3% (364) reporting some forms of ACEs, with 27.6% (172), 16.3% (102), and 14.4% (90) being exposed to 1, 2, and ≥ 3 ACEs, respectively. The prevalence of health risk behaviors ranged from 6.0 to 34.2%. Overall, ACEs were associated with increased risk of smoking, binge drinking, suicide attempt, risky sexual behaviors, and illicit drug use. Logistic regression suggested that participants with ≥ 3 ACEs (OR, 3.62; 95% CI, 2.14-6.13) were more likely to engage in the unhealthy cluster, characterized by the presence of any health risk behavior, than those without ACE. CONCLUSION: ACEs were associated with individual and clustering of health risk behaviors among Zambia college students. Our study suggests that early intervention is needed to prevent long-term adverse health consequences in this population.

BACKGROUND: The correlation between superoxide dismutase 2 (SOD2) V16A variant and urological cancer susceptibility has been widely studied, however, with divergent results. RESULTS: Totally, 9,910 cancer patients and 11,239 control subjects were enrolled. V16A variant is associated with an increased susceptibility to urological cancer (A-allele vs. V-allele: OR = 1.06, 95% CI = 1.00 - 1.13, P = 0.047; AA+AV vs. VV: OR = 1.09, 95% CI = 1.02 - 1.16, P = 0.008), especially for prostate cancer (PCa). Serum SOD2 level of PCa patients with VV+VA genotypes was lower than in those with AA genotypes. SOD2 expression is downregulated in both prostate and bladder cancer, as compared to the control. Furthermore, SOD2 was found to be downregulated in more advanced PCa participants, as compared to the ones in early stages. PCa subjects with low SOD2 expression displayed a shorter disease-free survival (DFS) time compared to that of the high SOD2 expression counterparts. CONCLUSIONS: The SOD2 V16A variant may be associated with increased urological cancer susceptibility, especially for prostate cancer. METHODS: A pooled analysis utilizing odds ratios (ORs), in silico tools and ELISA was adopted to demonstrate this association. We also used immunohistochemical staining (IHS) to assess SOD2 expression.

INTRODUCTION: Evidence on the combined effect of fruit and vegetable intake and total fat intake on hypertension is scarce. This study aimed to explore the relationship among fruit and vegetable intake, fat intake, and hypertension risk among Chinese adults. METHODS: Individuals who participated in the China Health and Nutrition Survey (2004, 2006, 2009, and 2011) and were free of hypertension at baseline (n=4,368) were categorized into quartiles (Q1, lowest; Q4, highest) according to their dietary fruit and vegetable intake and fat intake. Generalized estimation equation models, adjusted for confounders, were used to explore the relationship of fat intake with hypertension and systolic and diastolic blood pressure among all adults and within quartiles of fruit and vegetable intake. Data analyses were performed in 2018. RESULTS: A total of 1,086 adults developed hypertension during follow-up. In the total population, the OR of the highest quartile of fat intake was 1.40 (95% CI=1.12, 1.75) compared with the lowest. Among individuals with low fruit and vegetable intake, the odds of hypertension for those in Q3 (OR=1.97, 95% CI=1.37, 2.83) and Q4 (OR=1.81, 95% CI=1.14, 2.90) of fat intake, compared with individuals in Q1, were even higher than for the overall sample. For each 50-gram increase in FI per day, the ORs of hypertension increased from fat intake Q1 to Q4 among all respondents and those with low fruit and vegetable intake, but not among those with high fruit and vegetable intake. Systolic blood pressure increased by 1.08 mm Hg (95% CI=0.03, 2.13) per 50-gram fat intake per day increment in the fruit and vegetable intake Q1 group, whereas the association was not significant in the fruit and vegetable intake Q2-Q4 groups. CONCLUSIONS: Fruit and vegetable intake modifies the relationship between fat intake and hypertension, whereby high fruit and vegetable intake may offset the detrimental effect of fat intake on hypertension. Increased fruit and vegetable intake and controlled fat intake are recommended to prevent hypertension in Chinese adults.

Objective: This study aimed to assess the impact of a health education intervention on health behaviors, self-efficacy, and well-being among college students. Participants: Between March and October 2016, a total of 532 undergraduates participated. Methods: A theory-based intervention was conducted at Wuhan University, China. Participants were assigned to a control or intervention group (IG). The IG attended a 7-week health education class on knowledge, attitude, and practice of health behaviors. Results: Participants in the IG, compared with those in the control group (CG), reported significantly increased prevalence of high physical activity and regular breakfast, as well as lower screen time, sugar beverage intake, and Internet addiction tendency. Furthermore, intervention students improved in health behavior scores (p = 0.040), compared with the CG, while the changes in subjective well-being and self-efficacy remained similar between the two groups. Conclusions: Health education may promote health behaviors among Chinese college students.

Penicillum citreonigrum XT20-134 (MCCC 3A00956) is a fungus with cytotoxic activity, derived from deep-sea sediment. Five new compounds, adeninylpyrenocine (1), 2-hydroxyl-3-pyrenocine-thio propanoic acid (2), ozazino-cyclo-(2,3-dihydroxyl-trp-tyr) (3), 5,5-dichloro-1-(3,5-dimethoxyphenyl)-1,4-dihydroxypentan-2-one (4), and 2,3,4-trihydroxybutyl cinnamate (5), together with 19 known compounds (6-24), were isolated from an ethyl acetate (EtOAc) extract of its fermentation. The structures of the new compounds were comprehensively characterized by high-resolution electrospray ionization-mass spectrometry (HR-ESI-MS), 1D and 2D nuclear magnetic resonance (NMR). All isolates were evaluated for their cytotoxic activities. The heteroatom-containing new compounds 2 and 4 showed potent cytotoxicity to the human hepatoma tumor cell Bel7402 with IC50 values of 7.63 ± 1.46, 13.14 ± 1.41 µM and the human fibrosarcoma tumor cell HT1080 with IC50 values of 10.22 ± 1.32, 16.53 ± 1.67 µM, respectively.

Fusarium solani H915 (MCCC3A00957), a fungus originating from mangrove sediment, showed potent inhibitory activity against tea pathogenic fungus Pestalotiopsis theae. Successive chromatographic separation on an ethyl acetate (EtOAc) extract of F. solani H915 resulted in the isolation of five new alkenoic diacid derivatives: fusarilactones A-C (1-3), and fusaridioic acids B (4) and C (5), in addition to seven known compounds (6-12). The chemical structures of these metabolites were elucidated on the basis of UV, IR, HR-ESI-MS, and NMR spectroscopic data. The antifungal activity of the isolated compounds was evaluated. Compounds with a ß-lactone ring (1, 2, and 7) exhibited potent inhibitory activities, while none of the other compounds show activity. The ED50 values of the compounds 1, 2, and 7 were 38.14 ± 1.67, 42.26 ± 1.96, and 18.35 ± 1.27 µg/mL, respectively. In addition, inhibitory activity of these compounds against 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) synthase gene expression was also detected using real-time RT-PCR. Results indicated that compounds 1, 2, and 7 may inhibit the growth of P. theae by interfering with the biosynthesis of ergosterol by down-regulating the expression of HMG-CoA synthase.

BACKGROUND: Few studies have investigated the effect of smoking on type 2 diabetes in women compared with men, even though several epidemiological studies provided a clear picture of the risk among the entire population. METHODS: We systematically searched PubMed and Embase up to August 2017 for prospective studies that were stratified by sex with measures of the relative risk (RR) for type 2 diabetes and current smoking compared with non-smoking. The sex-specific RRs and their ratios (RRRs), comparing women with man, were pooled using random-effects models. RESULTS: Seventeen articles were identified including 20 prospective cohorts with 5 077 289 participants and 223 084 incident cases of type 2 diabetes. The pooled RRR suggested a similar risk of type 2 diabetes associated with smoking in women compared with men (RRR: 0.98, 95% confidence interval [CI]: 0.96-1.01). Furthermore, no significant sex difference in the RR was found between former smokers and those who had never smoked (RRR: 0.98, 95% CI: 0.92-1.04). CONCLUSIONS: The findings of this meta-analysis indicate that female smokers had similar risk of type 2 diabetes with male smokers.

To investigate structurally novel and anti-neuroinflammatory natural compounds from marine-derived microorganisms, the secondary metabolites of Aspergillus terreus Y10, a fungus separated from the sediment of the coast in the South China Sea, were studied. Three new compounds (2â»4), with novel open-ring butenolide skeletons, were isolated from the ethyl acetate extract of the culture medium. In addition, a typical new butenolide, asperteretal F (1), was found to dose-dependently inhibit tumor necrosis factor (TNF-α) generation with an IC50 of 7.6 µg/mL. The present study shows the existence of open-ring butenolides, and suggests that butenolides such as asperteretal F (1) are a promising new anti-neuroinflammatroy candidate for neurodegenerative diseases.

BACKGROUND: The prevalence of childhood obesity is increasing and psychological disorder is a common comorbidity of obesity. We investigated the associations of physical activity (PA) and fruit and vegetable (FV) intake with well-being and depressive symptoms among obese schoolchildren. METHODS: Participants included 188 obese children aged 9.8 ± 0.7 years living in Wuhan, China. Self-administered questionnaires were used to collect the children's PA and FV intake information. PA was considered to be high if the child participated in sport and/or vigorous free play at least 3 days per week with 60 min per day, while sufficient FV intake was defined as consuming FV 5 times per day. Children's well-being and depressive symptoms were assessed by standard questionnaires. Multiple logistic regression was performed to determine the odds ratios (ORs) and 95% confidence intervals (CIs) of the relationships of PA and FV intake with well-being and depressive symptoms. RESULTS: High PA and sufficient FV intake were independently associated with significantly decreased risks for depressive symptoms (for PA, OR: 0.39, 95% CI: 0.16-0.92; for FV, OR: 0.21, 95% CI: 0.08-0.55) and poor well-being (for PA, OR: 0.35, 95% CI: 0.16-0.74), respectively. Furthermore, interactive inverse associations were observed between combined high PA and sufficient FV intake with poor well-being and depressive symptoms. Compared to their counterparts, children with high PA and sufficient FV intake had significantly reduced risk for poor well-being (OR: 0.16, 95%CI: 0.05-0.55) and depressive symptoms (OR: 0.12, 95% CI: 0.03-0.48). CONCLUSIONS: High PA and sufficient FV intake are inversely associated with the risks of poor well-being and depressive symptoms among obese Chinese schoolchildren.

PURPOSE: Fruit and vegetable intake has been inversely associated with the risk of hypertension; however, there is inconsistent evidence on the long-term association. Given this gap in the literature, it is necessary to identify evidence from large prospective studies, especially in China, where insufficient evidence exists. Thus, we examined the association of fruit and vegetable intake with incident hypertension in Chinese adults. METHODS: We conducted analyses among 5659 Chinese adults aged 18-64 years, free of cardiovascular disease, cancer, and hypertension in the 2006 wave of the China Health and Nutrition Survey. Fruit and vegetable intake was assessed using consecutive 24-h recalls. Incident hypertension was identified from the 2011 wave of the survey. RESULTS: A total of 866 participants developed incident hypertension. The relative risks (RRs) and 95% confidence intervals (CIs) of hypertension were 0.74 (0.55-0.99), 0.65 (0.48-0.88), 0.68 (0.50-0.92), and 0.73 (0.53-0.99) comparing each quintile group of fruit and vegetable intake with the lowest quintile group. These associations attenuated for the change of intake but remained significant for the fourth quintile, of which the RR (95% CI) was 0.65 (0.47-0.89). The magnitude of association was stronger among those who were younger, female, overweight and had prehypertension. When examined separately, fruit intake was more strongly and significantly associated with lowering BP than vegetable intake. Adding body mass index to the models attenuated all associations. CONCLUSIONS: Greater long-term intake and increased intake of fruit and vegetables may reduce the risk of developing hypertension in Chinese adults.

BACKGROUND: Unbalanced dietary intake and insufficient physical activity (PA) have been recognized as risk factors for metabolic syndrome (MetS). We aimed to examine the independent and combined effects of fruit and vegetables (FV) intake and PA on MetS. METHODS AND FINDINGS: A cross-sectional survey was conducted among residents of China in 2009, with fasting blood samples collected. Participants were divided into sufficient/insufficient FV intake and adequate/ inadequate PA groups according to self-reported questionnaires. MetS was defined using the NCEP-ATPIII criteria. The difference of individual MetS components was compared across different PA or FV groups. Multivariable logistic regression was used to assess association between FV/PA and the risk of MetS. A total of 7424 adults were included in the current study. MetS was prevalent in 28.7% of participants, with 24.7% and 32.9% in male and female, respectively. Compared with those with inadequate PA and insufficient FV intake, participants with the combination of adequate PA and sufficient FV intake had the lowest risk of MetS (OR = 0.69,95%CI: 0.59-0.82), following by the group with adequate PA time but insufficient FV intake (OR = 0.74, 95%CI:0.65-0.83). CONCLUSION: Findings of the current study show that the combination of sufficient FV intake and adequate PA was significantly associated with reduced MetS risk among adult residents of China.

SCOPE: Epidemiologic studies assessing the association between dietary total flavonoids intake and the risk of mortality from cardiovascular disease (CVD) and all causes have yielded inconsistent results. Therefore, we conducted a dose-response meta-analysis to investigate this association. METHOD AND RESULTS: We searched PubMed and Embase databases from January 1966 through May 2016 and examined the references of retrieved articles to identify relevant prospective cohort studies. The random-effect model was used to calculate the summary risk estimates and dose-response analysis was performed. Ten studies were included in the present meta-analysis. The relative risk (RR) of all-cause mortality for the highest versus lowest category of total flavonoids intake was 0.82 (95% confidence interval (CI): 0.72-0.92). Dose-response analysis showed that those consuming 200 mg/day of total flavonoids had the lowest risk of all-cause mortality. Furthermore, a marginally significant association was found between dietary total flavonoids consumption and risk of death from CVD (summary RR: 0.85; 95% CI: 0.70-1.03; P = 0.099) and coronary heart diseases (summary RR: 0.74; 95% CI: 0.54-1.02; P = 0.069), respectively. CONCLUSION: The meta-analysis provides strong evidence for the recommendation of consuming flavonoids-rich food to reduce risks of mortality from all causes as part of a healthy diet among general adults.
