[Spatiotemporal Characterization and Driving Factors of Fine Particulate Matter and Its Chemical Components in the Huaihe River Basin].

According to the data sets of fine particulate matter （PM） and its components in 35 cities in the Huaihe River Basin from 2015 to 2021, the temporal and spatial distribution patterns of pollutants were analyzed. The influence of meteorological factors on PM concentrations was examined using a random forest model. The original series of PM, sulfate （SO）, nitrate （NO）, ammonium salt （NH）, organic matter （OM）, and black carbon （BC） were rebuilt using KZ （Kolmogorov-Zurbenko） filtering and multiple linear regression （MLR） to quantify the effects of meteorological conditions.

[Estimation of Regional Background Ozone in Henan Province from 2019 to 2021].

Clarifying the regional transmission and local generation contributions of ozone （O） is important for controlling O pollution. To quantify the regional background and spatial-temporal variations of O, a comprehensive study was conducted using multiple methods including principal component analysis （PCA） and TCEQ, with Henan Province as a case study. Based on monitoring data from 59 national sites in Henan Province during 2019-2021, four methods were employed to estimate the regional background of O.

[Spatial-temporal Variations and Driving Factors of Surface Ozone over the Qinghai-Xizang Plateau from 2015 to 2021].

Kolmogorov-Zurbenko （KZ） filtering was employed to separate the original O-8h series into components at different time scales. Then, multiple linear regression of meteorological variables was used to quantitatively isolate the effects of meteorology and emissions.

[Evaluation of Changes in PM Exposure Concentration and Health Risk for Urban Resident in Zhengzhou Based on High Spatial Resolution Grids].

In recent years, complex air pollution with the characteristic pollutant of PM has remained serious in China. Long term exposure to PM might harm residential health and can increase premature death from specific diseases. The annual average concentration of PM in Zhengzhou was much higher than the national secondary standard, which has an extremely negative impact on the health of residents.

[One-year Simulation of Air Pollution in Central China, Characteristics, Distribution, Inner Region Cross-transmission, and Pathway Research in 18 Cities].

Air pollution in Henan province is serious and is significantly impacted by pollution transmission and interactions with surrounding areas. The emission sources in 18 cities in Henan province were labeled and applied to the WRF-CMAQ traceability model for simulation in January, April, July, and October of 2017. The pollutant distribution results showed that due to the combined influence of emissions and meteorology, the concentrations of PM, NO, and SO in Henan province were the highest in winter and the lowest in summer.

[Spatiotemporal Variations in Fine Particulate Matter and the Impact of Air Quality Control in Zhengzhou].

To study the spatiotemporal variations in fine particulate matter (PM) and the impact of air quality management in autumn and winter in Zhengzhou, five sites were selected to collect PM samples from the autumn of 2017 to the winter of 2018, and the characteristics of the chemical components were analyzed. The positive matrix factorization (PMF) model was also applied to identify the sources of PM, and the effect of air quality control was evaluated to provide support for air quality control in autumn and winter in the next stage. The PM concentrations in the four seasons in Zhengzhou were ranked as winter > autumn > spring > summer.

[Health Impact Attributable to the Control of PM Pollution in China During 2013-2017].

To evaluate the health benefits brought about by air environmental treatment and determine the main drivers of health risk, we calculated the health and economic benefits attributed to PM control in Eastern and Central China from 2013 to 2017 by combining PM concentrations with a human activity enhanced exposure-response model. The relative contributions of changes in four factors related to the PM health burden were also quantified, namely total population, population aging, baseline mortality rates, and ambient exposure. The results show that the population weighted PM concentration decreased by 28.

[Evaluation of the Reduction in PM Concentration During the National Traditional Games of Ethnic Minorities in Zhengzhou].

To evaluate the effect of the implementation of emission reduction measures and the improvement in air quality during the National Traditional Games of Ethnic Minorities in Zhengzhou, a series of online instruments were used to continuously observe air pollutants and components of PM from August 5 to September 30, 2019. Three cases, including before emission reduction (August 5-24), during emission reduction (August 25 to September 18), and after emission reduction (September 19-30), were classified by the implementation of control measures. The results show that the growing concentration of PM after the cancellation of emission abatement measures (11.

[Characteristic of Surface Ozone and Meteorological Parameters Analysis in Anyang City].

This study uses the national ambient air quality station data of Anyang City from 2014 to 2017 to analyze the characteristics and variation rules of ozone (O) in different functional zones (urban, suburban, and industrial), and also studies meteorological influencing factors and potential source distributions of O pollution. The results showed that the O concentration in Anyang increased significantly between 2014 and 2017, whereby pollution started to advance from 2015 and the earliest occurrence of an O pollution episode was in April 2017. The 90 percentile and average concentrations of O in the industrial zone increased at faster rates (average annual growth of 16.

Gender impacts on the correlations between nonalcoholic fatty liver disease and hypertension in a Chinese population aged 45-60 y.

Unlabelled: No previous study has reported the association between nonalcoholic fatty liver disease (NAFLD) and the risk of hypertension in the Chinese population. Therefore, the aim of this study was to evaluate the relationship between NAFLD and hypertension in a middle-aged Chinese population. The study subject was (a group of) 1006 Chinese adults aged 45-60 y in Shandong Province who participated in the Weifang Nutrition and Health Survey (2014-2015).

Atorvastatin Treatment for Atrial Fibrillation Reduces Serum High-Sensitivity C-Reactive Protein Levels.

We investigated whether serum hs-CRP levels predict the efficacy of atrial fibrillation (AF) treated with atorvastatin. Bibliographic databases were exhaustively searched for studies relevant to the research topic. Newcastle-Ottawa Scale (NOS) criteria, combined with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS), were applied for study quality assessment.

Transforming growth factor β-interacting factor-induced malignant progression of hepatocellular carcinoma cells depends on superoxide production from Nox4.

Hepatocellular carcinoma (HCC) is one of the most deadly malignancies worldwide because of its high recurrence rate, high metastatic potential, and resistance to drugs. Elucidation of the mechanisms underlying malignancy in HCC is needed to improve diagnosis, therapy, and prognosis. Previously, we showed that transforming growth factor β-interacting factor (TGIF) antagonizes arsenic trioxide-induced apoptosis of HepG2 cells and is associated with poor prognosis and progression of urothelial carcinoma in patients after radical nephroureterectomy.

Involvement of TG-interacting factor in microglial activation during experimental traumatic brain injury.

Traumatic brain injury (TBI) is a complex injury involving several physiological alterations, potentially leading to neurological impairment. Previous mouse studies using high-density oligonucleotide array analysis have confirmed the upregulation of transforming growth-interacting factor (TGIF) mRNA in TBI. TGIF is a transcriptional corepressor of transforming growth factor beta (TGF-β) signaling which plays a protective role in TBI.

Synthesis of diastereometrically pure cubane-like photodimers from 2,4-pentanediyl-bis-2-naphthoates.

Irradiation of (2R,4R)-(-)- and (2S,4S)-(+)-2,4-pentanediyl-bis-2-naphthoates (1R and 1S, respectively) in organic solutions exclusively results in cubane-like anti(HH) photodimers in 100% yield. Asymmetric induction with 100% diastereometric excess (de) has been achieved and the absolute configuration of the yielded diastereomers has been established. Moreover, irradiation of (2R,4S)-2,4-pentanediyl-bis-2-naphthoate (1M) gives cubane-like syn(HH) photodimers in 100% yield.

Enhancement of diastereoselectivity in photodimerization of alkyl 2-naphthoates with chiral auxiliaries via inclusion within γ-cyclodextrin cavities.

Irradiations of alkyl 2-naphthoates are known to result in four isomeric "cubane-like" photodimers: anti(HH)-2, syn(HH)-2, anti(HT)-2, and syn(HT)-2 where the anti(HH)-2, anti(HT)-2, and syn(HT)-2 consist of pairs of diastereomers. Here, chiral auxiliary and chiral microreactor strategies have been combined to achieve high diastereoselectivity in photodimerizations of an enantiomeric pair of 2-naphthoates with (R)- and (S)-1-methoxycarbonylethyl esters as chiral auxiliaries (1R and 1S). Thus, irradiations of their γ-cyclodextrin (γ-CD) complexes have been conducted.

Efficient and selective photodimerization of 2-naphthalenecarbonitrile mediated by cucurbit[8]uril in an aqueous solution.

The photodimerization of 2-naphthalenecarbonitrile (2-NpCN) in a cucurbit[8]uril (CB[8]) aqueous solution was investigated. Spectroscopic analysis and product distribution reveal that the use of CB[8] as a host inverted the product selectivity from photodimers 2 and 3 in cyclohexane to photodimer 1 in a CB[8] aqueous solution with a large rate acceleration under ambient temperature and pressure.

Stepwise photochemical-chiral delivery in gamma-cyclodextrin-directed enantioselective photocyclodimerization of methyl 3-methoxyl-2-naphthoate in aqueous solution.

Irradiation of methyl 3-methoxyl-2-naphthoate (2,3-NA) with lambda > 280 nm results in photocyclodimerization to produce cubane-like photocyclodimer 1 and the [4 + 4] intermediate 2. The optically pure enantiomers of the intermediate 2 have been achieved by high-performance liquid chromatography (HPLC) resolution on a chiralcel OJ-RH column. Comparison of the enantiomeric excess (ee) values for photocyclodimer 1 and the intermediate 2 obtained in gamma-CD aqueous solution reveals the stepwise photochemical-chiral delivery for the first time, which is recognized to be a consequence of an in situ increase in the ee value from 39% for the [4 + 4] intermediate 2 to 48% for photocyclodimer 1 upon irradiation of 2,3-NA in the presence of gamma-CD.
