The combined effects of polystyrene of different sizes and cadmium in mouse kidney tissues.

Environmental accumulation of nano- and microplastics pose serious risks to human health. Polystyrene (PS) is a polymer commonly used in the production of plastics. However, PS can adsorb cadmium (Cd), thereby influencing bioavailability and toxicity in vivo.

Detection of microplastics in domestic and fetal pigs' lung tissue in natural environment: A preliminary study.

Microplastics (MPs) are ubiquitous in the environment. However, it is unclear whether MPs are present in mammalian lungs through inhalation, and if so, could be possibly found in fetal tissues. In this study, we aim to determine the presence and characteristics of particles in domestic and fetal pig lung tissue in the natural environment.

Exposure to microplastics in the upper respiratory tract of indoor and outdoor workers.

The aim of this study was to determine the presence of microplastics (MPs) in the upper respiratory tract of indoor and outdoor workers, to assess the type and the extent of contamination. Sputum and nasal lavage fluid were collected, and plastic particles were quantitatively analyzed by polarizing microscopy and a laser direct infrared chemical imaging system. The polarized light microscopy results showed that suspicious MPs were found in the nasal lavage and sputum of both couriers and office staff, and the abundance of MPs in the nasal lavage of office staff was significantly higher than in couriers (P < 0.

Blood uptake and urine excretion of nano- and micro-plastics after a single exposure.

Nano- and micro-plastic (NMP) pollution has emerged as a global issue; however, uptake in the blood is controversial. Also, there is no evidence that NMPs are excreted via urine. This study was designed to clarify the time course of NMPs absorption in blood and the excretion in urine.

Incremental significance and sex discrepancies of neck circumference on the odds of ischaemic stroke: a multistage, population-based, cross-sectional study from Northeast China.

Objectives: Accumulated evidence suggests that neck circumference (NC) is associated with cardiometabolic risk factors. However, limited studies are available regarding the association between NC or height normalised NC (neck-to-height ratio (NHR)) and risk of ischaemic stroke (IS) in the Chinese population. Therefore, we aimed at examining the associations between NC or NHR and odds of IS and exploring the discrepancies between men and women.

Etiological and epidemiological features of acute meningitis or encephalitis in China: a nationwide active surveillance study.

Background: Acute meningitis or encephalitis (AME) results from a neurological infection causing high case fatality and severe sequelae. AME lacked comprehensive surveillance in China.

Methods: Nation-wide surveillance of all-age patients with AME syndromes was conducted in 144 sentinel hospitals of 29 provinces in China.

Etiological, epidemiological, and clinical features of acute diarrhea in China.

National-based prospective surveillance of all-age patients with acute diarrhea was conducted in China between 2009‒2018. Here we report the etiological, epidemiological, and clinical features of the 152,792 eligible patients enrolled in this analysis. Rotavirus A and norovirus are the two leading viral pathogens detected in the patients, followed by adenovirus and astrovirus.

Status and disparities of diabetes among urban and rural residents aged 40 years and older: insight from a population-based study in northeast China, 2017-2019.

Objectives: To evaluate the up-to-date epidemiology of diabetes in northeast China.

Methods: The cross-sectional study was conducted between September 2017 and March 2019 using a multistage, stratified and cluster random sampling method. 18 796 participants (28.

Epidemiology of dyslipidemia and associated cardiovascular risk factors in northeast China: A cross-sectional study.

Background And Aims: Management of dyslipidemia remains the cornerstone for prevention of cardiovascular diseases. We aimed to evaluate the epidemiology of dyslipidemia in northeast China.

Methods And Results: This cross-sectional survey was administered on 18,796 participants aged ≥40 years from September 2017 to March 2019 through a multistage, stratified, and cluster random sampling method.

Current heterosexual marriage is associated with significantly decreased levels of anxiety symptoms among Chinese men who have sex with men.

Background: The high heterosexual marriage rate could be a 'double-edge' sword for the emotional health of Chinese men who have sex with men (MSM). The aim of this study was to determine if current marriage and breakdown of marriage (divorce) have different effects on the mental health of Chinese MSM.

Methods: Eight hundred seven MSM were recruited using respondent-driven sampling from four cities in northeastern China.

Direct detection from clinical sputum samples to differentiate live and dead Mycobacterium Tuberculosis.

Background: In this study, we aimed to optimize the condition of propidium monoazide (PMA) treatment for direct detection of Mycobacterium tuberculosis (MTB) from clinical specimens.

Methods: The light exposure time, dark incubation time, bacterial load, and PMA concentration were varied to determine the optimal condition of PMA treatment.

Results: Overall, the maximum ΔCq value was observed in the group receiving a light exposure time of 20 minutes, which was significantly higher than the others (P < 0.

Analysis of Requirements for Developing an mHealth-Based Health Management Platform.

Background: Studies have consistently shown that mobile and Web-based apps have positive impacts on people's daily lifestyles, health management, and disease treatment. As the development of medical and health informatization in China has evolved, different kinds of mobile-based apps for individuals and hospitals have been developed by software vendors. However, doubts and challenges posed by the media have prevented these apps from having a stable and substantial user base.
