Integrated analysis of remote sensing with meteorological and health data for allergic rhinitis forecasting in Tianjin.

Long time series of vegetation monitoring can be carried out by remote sensing data, the level of urban greening is objectively described, and the spatial characteristics of plant pollen are indirectly understood. Pollen is the main allergen in patients with seasonal allergic rhinitis. Meteorological factors affect the release and diffusion of pollen.

[Source and Cause Analysis of High Concentration of Inorganic Aerosol During Two Typical Pollution Processes in Winter over Tianjin].

Inorganic aerosol is the main component of haze days in winter over Tianjin. In this study, two typical high concentrations of secondary inorganic aerosol (SIA) processes, defined as CASE1 and CASE2, were selected during polluted days in January 2020 over Tianjin, and the effects of meteorological factors, regional transport, and chemical processes were comprehensively investigated combined with observations and numerical models (WRF-NAQPMS). The average SIA concentrations in CASE1 and CASE2 were 76.

[Spatio-temporal Distribution Characteristics of Secondary Aerosol in Beijing-Tianjin-Hebei Urban Agglomeration in Winter].

The secondary component is an important factor causing PM pollution in the Beijing-Tianjin-Hebei urban agglomeration in winter. In this study, the CO tracer method was used to estimate the secondary PM concentration of the Beijing-Tianjin-Hebei urban agglomeration in the winter of 2017-2021. The temporal and spatial distribution characteristics were analyzed, and the influencing factors of regional secondary PM were discussed.

[Exploring Formation of Ozone in Typical Cities in Beijing-Tianjin-Hebei Region Using Process Analysis].

As the problem of O pollution in the Beijing-Tianjin-Hebei region becomes increasingly prominent, it is of great significance to explore and analyze the ozone variation characteristics and causes of the pollution process in the Beijing-Tianjin-Hebei region for regional air pollution prevention and control. The observations in this study showed that high O concentration in spring and summer of the Beijing-Tianjin-Hebei region was higher in the south and lower in the north. The high O concentration in Beijing, Tianjin, and Shijiazhuang was often accompanied by the influence of southern wind.

[Analysis of Change and Driving Factors of PM Mass Concentration in Tianjin from 2000 to 2020].

Based on real-time tracking data, PM mass concentration, and meteorological observations of the Tianjin Meteorological Bureau and the Ecological Environment Bureau, combined with the fine particle meteorological condition diffusion index constructed using the environmental model, the change and driving factors of the PM mass concentration in Tianjin from 2000 to 2020 were studied to analyze the impact of meteorology on the atmospheric environment. The study showed that change in PM mass concentration in Tianjin took place in three stages from 2000 to 2020; the first stage showed a continuous increase from 2000 to 2007. The rapid increase in emissions in this stage was the dominant factor, and its effect was four times that of the annual fluctuation in meteorological conditions.

Maspin inhibits MCF-7 cell invasion and proliferation by downregulating miR-21 and increasing the expression of its target genes.

Maspin has been identified as a tumor suppressor gene in breast cancer, but the underlying regulatory mechanisms remain unclear. In the present study, maspin pcDNA was transfected into MCF-7 cells. microRNA (miR) microarray and reverse transcription-quantitative polymerase chain reaction was used for analysis; the results demonstrated that maspin may inhibit miR-10b, miR-21 and miR-451 expression in MCF-7 cells.

Comprehensive assessments of long-term sleep habits in epidemiological study: Validity and reliability of sleep factors questionnaire (SFQ) among Chinese women.

Objective: Epidemiological studies suggested that poor sleep is a potentially novel risk factor for several health outcomes currently; however, there are no validated questionnaires that can systematically measure sleep parameters within these studies. We evaluated the reliability and validity of 17-item sleep factors questionnaire (SFQ), which was developed to comprehensively assess long-term sleep habits for the Jiujiang Breast Cancer Study (JBCS), Jiujiang, China.

Methods: The participants included 100 women aged 18-74years, who were randomly selected from the JBCS project, and completed a SFQ at baseline and again 1year later, and 4 quarterly 30 consecutive days (a total of 120days) sleep diaries over this same year.

[Analysis of epidemic situation and control strategy of schistosomiasis in Jiu- jiang City from 2008 to 2014].

Objective: To understand the epidemic situation of schistosomiasis in Jiujiang City, so as to provide the evidence for formulating further control strategy.

Methods: The data of schistosomiasis control were collected in Jiujiang City from 2008 to 2014. and the indicators including the annual schistosome infections of human and cattle, acute schistosome infection, outbreak of schistosomiasis endemic, schistosome infected Oncomelania hupensis snails were analyzed statistically.

An evidence-based assessment for the association between long-term exposure to outdoor air pollution and the risk of lung cancer.

Although outdoor air pollution has been identified as carcinogenic to humans, the magnitude of the relative risk (RR) and the 95% confidence interval (CI) for lung cancer in relation to outdoor air pollution remain uncertain. On a global scale, we quantified the risk of lung cancer associated with long-term exposure to outdoor air pollution using a meta-analytic approach. Relevant cohort studies from two databases (PubMed and Web of Science) through 31 May 2014 were searched, and a total of 21 cohort studies were identified in the analysis.

An evidence-based appraisal of global association between air pollution and risk of stroke.

Background: The aim of this study was to evaluate the transient effects of air pollutants on stroke morbidity and mortality using the meta-analytic approach.

Methods: Three databases were searched for case-crossover and time series studies assessing associations between daily increases in particles with diameter<2.5 μm (PM2.

Light exposure at night, sleep duration, melatonin, and breast cancer: a dose-response analysis of observational studies.

Evidence from observational studies on light at night (LAN) exposure, sleep duration, endogenous melatonin levels, and risk for breast cancer in women is conflicting. This led us to conduct a dose-response analysis of published observational data. Pertinent studies were identified by searching Medline, Web of Science, and EMBASE through April 2013.

Tea consumption and risk of type 2 diabetes: a dose-response meta-analysis of cohort studies.

Tea consumption has inconsistently been shown to be associated with the risk of type 2 diabetes (T2D). The aim of the present study was to conduct a dose-response meta-analysis of cohort studies assessing the association between consumption of tea and risk of developing T2D. Pertinent studies were identified by searching PubMed, Web of Science and EMBASE through 31 March 2013.

[Determination of trace metals in atmospheric dry deposition with a heavy matrix of PUF by inductively coupled plasma mass spectroscopy after microwave digestion].

Interest in atmospheric dry deposition results mostly from concerns about the effects of the deposited trace elements entering waterbody, soil and vegetation as well as their subsequent health effects. A microwave assisted digestion method followed by inductively coupled plasma mass spectrometric (MAD-ICP/MS) analysis was developed to determine the concentrations of a large number of trace metals in atmospheric dry deposition samples with a heavy matrix of polyurethane foam (PUF). A combination of HNO3-H2O2-HF was used for digestion.
