Visualizing epidemiological models for policy: Design principles for effective communication
Communicating scientific ideas to policy actors is a longstanding challenge, especially in epidemiological modeling where evidence is inherently uncertain. Central to this communication is visualization—the graphic representation of complex epidemiological modeling concepts through figures, plots, and charts. Effective model visualizations should be clear, simple, and easy to understand. This article brings theory from vision science to equip mod…
Dopamine system as a mediator between psychological symptoms and relapse tendency: A cross-sectional study in women undergoing compulsory rehabilitation in Zhengzhou, China

Codification and Prospect of China’s Codification of Environmental Law from the Perspective of Global Environmental Governance
Global environmental governance is the fundamental way to solve the human environmental crisis. With China as the world's largest emitter of greenhouse gases, the development of China's environmental law is a key component of global environmental governance. In order to better realize the construction of an ecological civilization, the compilation of China's Environmental Code has been officially put on the work schedule of the legislature. The c…
Pictures Library of Smoking Cravings: Development and Verification of Smokers and Non-smokers
Background: The cue-induced craving by addiction related materials is commonly employed in addiction research; however, no existing standardized picture database based on the expectation model of craving has been developed. We prepared and validated a Pictures Library of Smoking Cravings (PLSC) in this study. Methods: We captured pictures 366 smoking and 406 control pictures (matched in content).

Global urbanicity is associated with brain and behaviour in young people
Urbanicity is a growing environmental challenge for mental health. Here, we investigate correlations of urbanicity with brain structure and function, neuropsychology and mental illness symptoms in young people from China and Europe (total n = 3,867). We developed a remote-sensing satellite measure (UrbanSat) to quantify population density at any point on Earth. UrbanSat estimates of urbanicity were correlated with brain volume, cortical surface a…
Shoreline Changes Along the Coast of Mainland China—Time to Pause and Reflect
Shoreline changes are of great importance for evaluating the interaction between humans and ecosystems in coastal areas. They serve as a useful metric for assessing the ecological costs of socioeconomic developmental activities along the coast. In this paper, we present an assessment of shoreline changes along the eastern coast of mainland China from ~1990 to 2019 by applying a novel method recently developed by us. This method which we call the …
Privacy and the Panopticon: Online mass surveillance’s deterrence and chilling effects
The Panopticon is a popular metaphor in discussions about mass surveillance. Drawing on deterrence theory and chilling effects, we provide two empirical tests of this analogy to examine whether perceptions of online government surveillance suppress or entirely eradicate an array of sensitive online activities. Study 1 indicates that surveillance significantly deters individuals’ intentions to engage in illegal offenses, an effect that extends to …

Online Surveillance’s Effect on Support for Other Extraordinary Measures to Prevent Terrorism
The U.S. National Security Agency argues that online mass surveillance has played a pivotal role in preventing acts of terrorism on U.S. soil since 9/11. But journalists and academics have decried the practice, arguing that the implementation of such extraordinary provisions may lead to a slippery slope. As the first study to investigate empirically the relationship between online surveillance and support for other extraordinary measures to preve…

Statistical Analysis on Detecting Recombination Sites in DNA-β Satellites Associated with Old World Geminiviruses
Although exchange of genetic information by recombination plays an important role in the evolution of viruses, it is not clear how it generates diversity. Understanding recombination events helps with the study of the evolution of new virus strains or new viruses. Geminiviruses are plant viruses which have ambisense single-stranded circular DNA genomes and are one of the most economically important plant viruses in agricultural production. Small …
Pholidota chinensis alleviates azoxymethane/dextran sulfate sodium-induced colorectal carcinogenesis through inhibition of TLR4 and COX-2
Background: Inflammatory bowel disease (IBD) always progresses to colorectal cancer (CRC) which is the second most frequent cause of death by cancer. It is about 2% of population in the lifetime worldwide who at the risk for development of CRC. Oxaliplatin is an effective anticancer drug used for the treatment of advanced CRC; however, it always causes a robust painful neuropathy. Pholidota chinensis is a Chinese folk herbal medicine which was us…

Reducing waiting time and raising outpatient satisfaction in a Chinese public tertiary general hospital-an interrupted time series study
The interventions aimed at reducing waiting time and raising patient satisfaction in Fujian Provincial Hospital are effective. A long-lasting reduction effect on waiting time for filling prescriptions was observed because of carefully designed continuous efforts, rather than a one-time campaign, and with appropriate incentives implemented by a taskforce authorized by the hospital managers. This case provides a model of carrying out continuous qua…

Global Identification of HIF-1α Target Genes in Benzene Poisoning Mouse Bone Marrow Cells
Benzene is a hematopoietic toxicant, and hematopoietic cells in bone marrow (BM) are one of the main targets for its action, especially hematopoietic stem cells (HSCs). Hypoxia-inducible factor-1α (HIF-1α) is associated with the metabolism and physiological functions of HSCs. We previously found that the mechanism of regulation of HIF-1α is involved in benzene-induced hematopoietic toxicity. In this study, chromatin immunoprecipitation sequencing…

PTP4A3, A Novel Target Gene of HIF-1alpha, Participates in Benzene-Induced Cell Proliferation Inhibition and Apoptosis through PI3K/AKT Pathway
Benzene, a commonly used chemical, has been confirmed to specifically affect the hematopoietic system as well as overall human health. PTP4A3 is overexpressed in leukemia cells and is related to cell proliferation. We previously found that HIF-1alpha was involved in benzene toxicity and PTP4A3 may be the target gene of HIF-1alpha via ChIP-seq. The aim of this study is to confirm the relationship between HIF-1alpha and PTP4A3 in benzene toxicity, …
