Problem gambling poses serious harm to individuals and societies worldwide. This study aims to investigate the relationship between stressful life events and problem gambling, and further explore the mediating role of coping strategies and magical thinking. Currently, the research on problem gambling is widely conducted worldwide. However, due to the unique characteristics of China's gambling industry, research on problem gambling conducted in the Chinese mainland has always been an underrepresented area in international gambling research. This study recruited participants from a province in central China, and data from 483 of them were ultimately analyzed. The data analysis results indicate that task-oriented coping, emotion-oriented coping, avoidance-oriented coping, and magical thinking all serve as mediators in the relationship between stressful life events and problem gambling. Emotion-oriented coping and magical thinking, avoidance-oriented coping and magical thinking, all serve as serial mediators in the relationship between stressful life events and problem gambling. Task-oriented coping and magical thinking did not act as serial mediators in this relationship. This study demonstrates that helping problem gamblers develop effective coping strategies and reduce their level of magical thinking is crucial for treating their problem gambling.

Digital literacy has been increasingly important among workers in the labour market, and it also has been viewed as a micro reflection of the growing of China's digital economy. Internet use is an integral part of workers' digital literacy, which has a significant influence on entrepreneurial decision-making. This paper aims to explore the direct impact of Internet use on entrepreneurship, analyzing the mechanism and group differences of Internet use. It has a practical meaning to China's policies of promoting employment. Based on the data of China Labour Dynamics Survey (CLDS), the paper uses Probit model and 2SLS regression analysis to examine the direct impact of Internet use on entrepreneurship, and to analyze its mechanism by adopting the mediation effect model. The study indicates that Internet use has significantly increased the probability of starting a business, the impact has been stronger on the new generation, rural residents and the groups with work experience. Further analysis shows that Internet use not only increases venture capital, social capital and income, but also helps to shape individual workers' learning ability, which has an indirect effect on promoting entrepreneurship. The above results show the way of promoting workers' willingness of entrepreneurship, which are expanding Internet access, promoting policies of improving workers' Internet skills, focusing on cultivating comprehensive cognitive abilities including risk awareness and learning abilities.

In the rapid development of sponge city construction in China, porous asphalt pavement has been widely used. The high-viscosity modified asphalt used for porous asphalt pavements is utilised in a complex aging environment. In this study, infrared spectroscopy was used to test the changes in the functional groups of high-viscosity modified asphalt under the influence of ultraviolet radiation intensity, high temperature, and water corrosion conditions. The research results showed that under the influence of several environmental factors, the high-viscosity modified asphalt has no chemical reaction but does undergo physical changes. From the perspective of the functional group index, the carbonyl index is more suitable for evaluating the degree of ultraviolet aging, and the sulfoxide group index is more suitable for evaluating the effect of temperature on aging. The high-viscosity modified asphalt aging kinetic models, established with different functional group indexes as indicators, have different activation energies. The aging kinetic model established with the carbonyl index is more suitable for simulating traditional thermal-oxidative aging. This study provides a better plan to reveal the influence of different environmental factors on the aging performance of high-viscosity modified asphalt under complex environmental conditions.

• Mulching farmlands contain higher level of microplastics in soils than non-mulching farmlands. • The particle size of microplastics is lower in the irrigation water than in the soils • Fragments rather than films or fibers dominated microplastic shapes in the cropped soils • No correlation was found between the microplastics abundance in soils and irrigation waters Microplastic contamination in agroecosystems raises great concerns. Here, we investigated the impacts of mulching and irrigation on microplastic accumulation in cropped soils. Sixty soil samples covering mulching and no-mulching farmlands, and forty-five irrigation water samples were collected for analysis. Microplastics were obtained from the soils using continuous air flotation followed by density separation. Stereomicroscopy and micro-Fourier transform infrared spectroscopy (μ-FTIR) were used for identification. Mulching soils contained larger amounts of microplastics than non-mulching soils, with 571 pieces kg−1 and 263 pieces kg−1, respectively, on average. The abundances of films and fibers were significantly (p < 0.05) higher in the mulching soils. Microplastics in the soils and waters were dominated by fragments and fibers, respectively. The particle size of the microplastics in soils mostly ranged from 1 to 3 mm, and primarily from 90 μm to 1 mm in waters. Multiple polymers, e.g. polyethylene, polypropylene, polyester, rayon, acrylic and polyamide, and shapes found in the soil microplastics indicate contributions from irrigation and plastic waste residues other than plastic mulching. Future studies might include the long-term accumulation of microplastics in agroecosystems from multiple sources under intensively managed cropping systems. [ABSTRACT FROM AUTHOR]

To evaluate the national prevalence depression of Chinese cancer patients and clarify its potential associated factors. Twelve databases were searched from database inception through October 31, 2022 for relevant studies published in English (PubMed MEDLINE, Ovid MEDLINE, Embase, Scopus, PsycINFO, and Cochrane and Web of Science) and Chinese (China National Knowledge Infrastructure, Wanfang, Weipu, Chinese Biomedical Literature Service System, Duxiu) that estimated point or period prevalence of depression, depressive disorder, or suicidal ideation as assessed by self-report scale or structured interview. 201 studies were eligible for inclusion in our meta-analyses. We found the national pooled prevalence rates of depression and suicidal ideation were 44.63 % (95 % CI 42.24 %–47.01 %) and 24.95 % (95 % CI 10.96 %–38.95 %), respectively. The pooled prevalence of depression was associated with study location, cancer type, comorbid chronic disease, and female sex (all P < 0.05). The distribution of the depression prevalence among cancer patients in mainland China was characterized by significant geographical variation and clustering. The highest pooled prevalence of depression was among gynecologic oncology patients. We recommend that more attention and resources be given to mental health problems such as depression and suicidal ideation among Chinese cancer patients, and that prevention programs be developed, especially in areas with a high prevalence of depression. • The pooled prevalence of depression among Chinese cancer patients was estimated. • This meta-analysis included 201 studies covering 27 provinces in mainland China. • Factors affecting the prevalence of depression in cancer patients were analyzed. • ArcGIS software was used to analyze the geographic distribution of depression.

• The coupled heat-light-water aging device has been proposed and developed. • The aging performance of HVA in complex environmental conditions was investigated. • The significance of different aging factors on road performance of HVA were demonstrated. • The microstructural morphologies revealed the aging mechanisms. During the rapid development of sponge city construction in China, the porous asphalt pavement has been widely applied. The high viscosity modified asphalt that is used for producing porous asphalt experiences complex aging circumstances. In this study, the aging performance of high viscosity modified asphalt was evaluated based on the simulated heat-light-water coupled conditions, in which different aging effects and degrees were considered. The complex aging simulation method was innovated that mainly composed of an UV radiator and an environmental cabinet. The dynamic shear properties, high and low-temperature performance, and microstructural morphology of aged high viscosity modified asphalt binders were evaluated through the DSR (temperature-frequency sweep scan, LAS, MSCR), BBR, and ESEM tests, respectively. The results of DSR and BBR test demonstrated that the coupled aging effects should be considered during the service period, since acid rain solution and UV light also led to significant influences on the viscoelastic properties, high and low-temperature performance, and fatigue performance as similar as high temperature. The observation of the microstructures illustrated the aging mechanisms of different environmental factors and their combined effects. This study could provide a better protocol for aging performance examination of high viscosity modified asphalt binder used for porous asphalt pavement considering complicated environmental conditions.

Purpose: Edaravone is a free-radical scavenger. Edaravone 30mg IV has been approved for use in the treatment of acute ischemic stroke in Japan and China, and for amyotrophic lateral sclerosis in Japan and the United States. Considering the inconvenience of IV infusion in clinical practice, an oral tablet formulation of edaravone was developed but failed in 2011 due to poor bioavailability. More recently, a sublingual (SL) tablet formulation of edaravone 30mg was developed by a Good Manufacturing Practices-compliant manufacturer in China. This study explored the bioavailability of the SL tablet of edaravone and aimed to provide evidence to support decision making in future clinical development., Methods: This 2-way crossover study was conducted in 10 healthy male volunteers. Eligible subjects were randomized, in a 1:1 ratio, to 1 of 2 dosing sequences: (1) SL edaravone 30mg, followed by edaravone 30mg IV infusion given over 30 minutes; or (2) edaravone 30mg IV infusion given over 30 minutes, followed by SL edaravone 30mg. The washout period between the 2 dosing periods was at least 24hours. Serial blood samples were collected in each dosing period. The bioavailability of the SL tablet was assessed using bioavailability analysis. Tolerability was evaluated throughout the study., Findings: The plasma concentration-time profile of the SL tablet was similar to that with the IV infusion. Amean (SD) C max of 2030.2 (517.2) ng/mL was reached within a median T max of 0.875hour, which was statistically significantly longer than the median T max with IV administration (0.5 hour). The C max with SL administration corresponded to 83.92% (90% CI, 73.22%-96.18%) of the C max with the start of IV infusion (2354.0 [336.6] ng/mL). The mean AUC 0-t with SL dosing was 5420.07 (1429.75) h · ng/mL, which corresponded to 91.94% (90% CI, 86.81%-97.39%) of the AUC 0-t with IV administration (5824.42 [1338.48] h · ng/mL). Two cases of adverse events were reported during the study; both were considered by the investigator to have been possibly not related to the study treatment., Implications: The bioavailability of the SL tablet of edaravone was 91.94%. Compared with IV administration, C max with SL administration was ∼17% lower and T max was statistically significantly longer. The exposure differences can be addressed by modifying the strength of the SL tablet, and then conducting a second study to demonstrate the pharmacokinetic bioavailability of the sublingually administered new strength versus IV infusion of edaravone., (Copyright © 2018 Elsevier Inc.
