Objective: Chinese college students' level of health literacy is low, so, we explored the effect of knowledge contests on health literacy (HL) among Chinese college students. Participants: Students from universities in Jiangsu, China. Methods: Two repeated cross-sectional studies were used to compare the effects of the college students' contests. Chi-square tests and variance analysis were used to compare the HL levels and scores, respectively; logistic regression was used for multivariate analysis. Results: The levels of HL after each contest were significantly higher than those in the baseline survey (p < 0.05). There were statistically significant score differences (p = 0.023 and p = 0.001) after the contests in the two studies. Multivariable analysis of HL contest showed that school, grade, profession, completion time, and contest history were statistically significant. Conclusions: HL among Chinese college students was low and it is helpful to regularly hold health knowledge contests to improve these levels, especially for most non-medical students.

Background There are currently no studies synthesizing the screening rate and influential factors of low-dose computed tomography (LDCT)-screened lung cancer in Asian population. Methods A systematic review was conducted, using both English and Chinese language databases on March, 2019. The pooled screening rate and estimated odds ratios (ORs) of influential factors were analyzed using random effects models. Subgroup and meta-regression analyses were also employed to explore the heterogeneity. Results The pooled LDCT lung cancer screening rate was 1.12% (95% confidence interval (CI): 0.94%, 1.32%), and increased with age. Adenocarcinoma and stage I lung cancer had higher screening rates. Analysis of influential factors in the general population showed that female and elder age (≥50 years) were significantly influencing LDCT lung cancer screening rate (for female, OR = 1.32, 95% CI: 1.15–1.52; for adults ≥ 50 years, OR = 1.94, 95% CI: 1.52–2.49). Meta-regression analysis indicated that the heterogeneity maybe significantly correlated with the sample size, risk population and source of population. Conclusions Unlike European and American populations, female and adults > 50 years rather than smoking adults were positively associated with screening rate in Asian populations. It is important to further study the benefits of lung cancer screening with LDCT in Asian populations. [ABSTRACT FROM AUTHOR]

Considering that basic bismuth nitrate Bi6O5(OH)3(NO3)5·3H2O (BBN) with a wide band gap energy (Eg = ~ 3.40 eV) could only respond to UV light, herein, BiOI-coupled BBN (BBN/BiOI) heterojunction at the size of several microns was synthesized by a grinding-assistant ion-exchange strategy. BiOI nanoparticles with relatively uniform diameters in the range of 0.22–0.71 μm attached on the surface of BBN at the size of around 10 μm. BBN/BiOI exhibited significantly enhanced visible-light photocatalytic activity for malachite green (MG, 20 mg/L) degradation at the premium BiOI content with initial I−/Bi3+ molar ratio of 0.8, and the degradation efficiency was increased to 90% from 4% of bare BBN and 44% of BiOI. Especially, the as-prepared BBN/BiOI possessed higher photocatalytic activity than that obtained by solution reaction, which should result from more intimate contact between BiOI and BBN due to mechanical force from grinding, as well as electrostatic attraction between positively charged surface of BBN and oxygen-terminated surface of BiOI. All these are beneficial to transfer and separation of photogenerated carriers, thus improving photo-quantum efficiency. Dissolution behavior of BBN in several dyes’ solution was clarified.

Background: This review aimed to provide constructive suggestions for the control and management of avian influenza through quantitative and qualitative evaluation of the impact of different live poultry market (LPM) interventions.Methods: Both English and Chinese language databases were searched for articles that were published on or before 9 November 2018. After extraction and assessment of the included literature, Stata14.0 was applied to perform a meta-analysis to explore the impacts of LPM interventions.Results: A total of 19 studies were identified. In total, 224 human, 3550 poultry, and 13 773 environment samples were collected before the intervention; 181 people, 4519 poultry, and 9562 environments were sampled after LPM interventions. Avian influenza virus (AIV) detection rates in the LPM environment (odds ratio [OR], 0.393; 95% confidence interval [CI], 0.262-0.589) and the incidence of AIV infection (OR, 0.045; 95% CI, 0.025-0.079) were significantly lower after LPM interventions, while interventions were not significantly effective in reducing AIV detection in poultry samples (OR, 0.803; 95% CI, 0.403-1.597).Conclusions: LPM interventions can reduce AIV human infections and the detection rate of AIV in market environments.

Two kinds of triphenylamine-derived solid-state emissive carbon dots (CDs) with orange and yellow color are facilely synthesized through solvothermal treatment, taking advantage of the nonplanar structure and good carrier mobility of triphenylamine unit. Theoretical calculations show that the triphenylamine structure could greatly inhibit the direct π-π stacking of aromatic skeletons and enhance the fluorescence properties of CDs in aggregation state. By adopting the CDs as single emissive layer, high-performance orange-color and green-color electroluminescent light-emitting diodes (LEDs) are successfully fabricated, with maximum brightness of 9450/4236 cd m -2 , high current efficiency of 1.57/2.34 cd A -1 and low turn-on voltage of 3.1/3.6 eV are respectively achieved. Significantly, white-color LED device is further prepared. This work provides a universal platform for the construction of novel solid-state emissive CDs with significant applications in photoelectric device., (© 2023 Wiley-VCH GmbH.)
