The effect of air pollutants on COPD-hospitalized patients in Lanzhou, China (2015-2019).

Background: Lanzhou is the largest heavy industrial city in northwest China and it is a typical geographical valley-like city. However, there are few studies on the relationship between air pollutants and COPD, and their respective sample sizes are small, resulting in inconsistent results. The aim of this study is to analyze the effects of air pollutants on COPD hospitalizations in Lanzhou, China.

Mesenchymal Stem Cell-Derived Exosomal Long Noncoding RNA MALAT1-201 Regulated the Proliferation, Apoptosis and Migration of Trophoblast Cells via Targeting miR-141.

Objective: MALAT1 has been confirmed to play a vital role in the progression of preeclampsia (PE). However, as one of the spliceosomes of MALAT1, the role and mechanism of MALAT1-201 in the progression of PE remain elusive. Mesenchymal stem cells (MSCs) correlate with angiogenesis and trophoblast formation and could maintain successful pregnancy, while the molecular mechanisms are still unclear.

Association of air pollutants and hospital admissions for respiratory diseases in Lanzhou, China, 2014-2019.

The aim of this study was to assess the effects of air pollutants on hospital admissions for respiratory disease (RD) by using distributed lag nonlinear model (DLNM) in Lanzhou during 2014-2019. In this study, the dataset of air pollutants, meteorological, and daily hospital admissions for RD in Lanzhou, from January 1st, 2014 to December 31st, 2019, were collected from three national environmental monitoring stations, China meteorological data service center, and three large general hospitals, respectively. A time-series analysis with DLNM was used to estimate the associations between air pollutants and hospital admissions for RD including the stratified analysis of age, gender, and season.
