EZH2 suppresses ferroptosis in hepatocellular carcinoma and reduces sorafenib sensitivity through epigenetic regulation of TFR2.

Enhancing sensitivity to sorafenib can significantly extend the duration of resistance to it, offering substantial benefits for treating patients with hepatocellular carcinoma (HCC). However, the role of ferroptosis in influencing sorafenib sensitivity within HCC remains pivotal. The enhancer of zeste homolog 2 (EZH2) plays a significant role in promoting malignant progression in HCC, yet the relationship between ferroptosis, sorafenib sensitivity, and EZH2 is not entirely clear.

[Establishment of High-Resolution Emissions Inventory in Wuhai and Its Application in Exploring the Causes of Ozone Pollution].

Wuhai is a typical coking industrial base including three industrial parks within its jurisdiction. The emission amount of air pollutants is considerable here, and O pollution has become serious in recent years. Clarifying the air pollutant emission characteristics and exploring the formation mechanism of O are the basis for objectively understanding the O pollution and formulating scientific prevention and control measures.

[Exploring Characteristics and Causes of Summer Ozone Pollution Based on Process Analysis in Wuhai].

In recent years, summer O pollution has become more severe in Wuhai, where the terrain is complex and industrial parks are densely distributed. However, the characteristics and formation mechanisms of this pollution have not yet been investigated and remain unclear. Analyzing the variation and formation mechanisms of O is crucial to the prevention and control of air pollution in this region.

[Establishment of a High-resolution Anthropogenic Emission Inventory and Its Evaluation Using the WRF-Chem Model for Lanzhou].

City-scale high-resolution anthropogenic emission inventories are an important tool for ambient air quality forecasting and early warning, the analysis of underlying causes, and policy making. At present, city-scale anthropogenic emissions inventories for use in air quality models are scarce for West China. By studying the literature on emission inventories, this paper establishes a city-scale anthropogenic emission inventory for Lanzhou (HEI-LZ16) as the basis for an air quality model.

[Nonlinear Response Characteristics and Control Scheme for Ozone and Its Precursors Based on Orthogonal Experimental Methods].

There is a highly nonlinear relationship between ozone concentrations and its precursor emissions in different regions and at different times, which makes developing effective prevention and control measures difficult. An orthogonal experimental method was introduced to assess the influence of ozone precursors and their interactions on ozone formation, clarify the sensitivity of ozone generation, and propose an optimal control scheme. Based on the WRF-Chem air quality model and an emission inventory of air pollutants in Wuhai City in 2018, this study used an ozone pollution event in the Haibowan urban area (August 17 to 20 2018) to investigate the nonlinear response of ozone formation to its precursors.

Effect of aldehyde dehydrogenase 2 gene polymorphism on hemodynamics after nitroglycerin intervention in Northern Chinese Han population.

Background: Nitroglycerin (NTG) is one of the few immediate treatments for acute angina. Aldehyde dehydrogenase 2 (ALDH2) is a key enzyme in the human body that facilitates the biological metabolism of NTG. The biological mechanism of NTG serves an important function in NTG efficacy.

[Some thoughts of the comparison of risk based soil environmental standards between different countries].

Risk-based soil environmental standard is one of the important aspects in contaminated soil management which have already been widely used in many countries. However, because of diversity in geographical, biological, social-cultural, regulatory and scientific aspects among each country, there are great distinctions on both titles and values of these soil environmental standards between different countries. Risk-based soil environmental standards and derivation process were introduced and compared in detail.

[Characterizing the plant uptake factor of As, Cd and Pb for rice and wheat cereal].

The statistical characteristics of plant uptake factor (PUF) of As, Cd and Pb for rice/wheat cereal were analyzed and summarized based on collected data in China. The data were selected and distinguished between field investigation and glasshouse experiment in which metal salts were added to clean soils as grown media. Results showed that the PUF median and range of As, Cd and Pb for rice cereal were 0.

[Development of lead benchmarks for soil based on human blood lead level in China].

Lead benchmarks for soil are mainly established based on blood lead concentration of children. This is because lead plays a dramatically negative role in children's cognitive development and intellectual performance and thus soil lead has been concerned as main lead exposure source for children. Based on the extensively collection of domestic available data, lead levels in air, drinking water are 0.
