Effects of fresh-salt water interaction on spatial variations of soil organic carbon in reed wetland of Yellow River Estuary.

Estuarine wetlands exhibit significant interaction between fresh and salt water, with long-term carbon sequestration capability. We set up 60 sampling sites in the reed wetlands of the fresh-salt water interaction zone of the Yellow River Estuary, covering four different zones of the weak-intensity fresh-salt water interaction zone (WIZ), medium-intensity fresh-salt water interaction zone (MIZ), high-intensity interaction fresh-salt water zone (HIZ) and strong-intensity fresh-salt water interaction zone (SIZ). We investigated how fresh-salt water interaction affected the spatial variation of soil organic carbon (SOC) storage.

[Effects of Water-salt Environment on Freshwater Wetland Soil C, N, and P Ecological Stoichiometric Characteristics in the Yellow River Estuary Wetland].

Carbon (C), nitrogen (N), and phosphorus (P) are important nutrients, and their ecological stoichiometric characteristics can reflect the quality and fertility capacity of soil, which is critical to understanding the stable mechanisms of estuarine wetland ecosystems. Under global changes, the increase in salinity and flooding caused by sea level rise will lead to changes in biogeochemical processes in estuarine wetlands, which is expected to affect the ecological stoichiometric characteristics of soil C, N, and P and ultimately interfere with the stability of wetland ecosystems. However, it remains unclear how the C, N, and P ecological stoichiometric characteristics respond to the water-salt environment in estuarine wetlands.

Research Progress on The Mechanism and Treatment of Inflammatory Response in Myocardial Ischemia-Reperfusion Injury.

Acute myocardial infarction can be treated aggressively with intravenous thrombolysis, percutaneous coronary intervention, and coronary artery bypass grafting; however, recanalization can cause myocardial ischemia-reperfusion injury (MIRI). This is an important reason that restricts the treatment effect of patients. After the ischemic myocardium is restored to perfusion, an inflammatory response can occur within minutes and peak within a few days.

[Spatial Distribution and Eco-stoichiometric Characteristics of Soil Nutrient Elements Under Different Vegetation Types in the Yellow River Delta Wetland].

To clarify the distribution characteristics and the ecological stoichiometric characteristics of nutrient elements in soils under different vegetation types, four typical natural wetlands, i.e., wetland, wetland, wetland, and wetland, as well as spp.

cFLIP Alleviates Myocardial Ischemia-Reperfusion Injury by Inhibiting Endoplasmic Reticulum Stress.

Purpose: Endoplasmic reticulum stress (ERS) plays a crucial role in myocardial ischemia-reperfusion injury (MIRI). Cellular FLICE-inhibitory protein (cFLIP) is an essential regulator of apoptosis and plays a major role in regulating ERS. The present study aimed to investigate the effects of long isoform cFLIP (cFLIP) on endogenous apoptosis and the mechanism of ERS in MIRI.

Cellular FADD-like IL-1β-converting enzyme-inhibitory protein attenuates myocardial ischemia/reperfusion injury via suppressing apoptosis and autophagy simultaneously.

Background And Aims: Myocardial ischemia/reperfusion injury (MI/RI) is a result of coronary revascularization, and often increases cell apoptosis and autophagy. Downregulated cellular FADD-like-IL-1β-converting enzyme-inhibitory protein (cFLIP) was associated with development of several myocardial diseases, whether overexpression of cFLIP can attenuate MI/RI remains unclear. This study aimed to determine the effects of cFLIP on apoptosis and autophagy in MI/RI.

Efficacy and safety of genotype-guided antiplatelet therapy versus standard treatment in 4,604 patients with CAD after PCI: a meta-analysis of randomized controlled trials.

To compare the efficacy and safety of genotype-guided antiplatelet strategy and standard treatment in patient with coronary artery disease (CAD) after percutaneous coronary intervention (PCI). Relevant studies published in Medline, Embase, CoChrane Library were searched for randomized controlled trials (RCTs) until August 2020. Studies were screened by selection criteria, quality assessed using the Cochrane Collaboration's tool.

Duration of dual antiplatelet therapy after percutaneous coronary intervention with implantation of second-generation drug-eluting stent: A meta-analysis of randomized controlled trials.

: The optimal duration of dual antiplatelet therapy (DAPT) in patients after PCI with implantation of a drugeluting stent is still controversial. We conducted a meta-analysis to compare the efficacy and safety of short term DAPT (≤ 3 months) followed by P2Y12 inhibitor monotherapy and standard DAPT (12 months) after PCI. : Relevant studies published in Medline, Embase, CoChrane Library were searched for randomized controlled trials (RCTs) until November 2019.

[Predicting the potential distribution of dominant species of the coastal wetland in the Yellow River Delta, China using MaxEnt model].

Soil and vegetation community were investigated using the method of kilometer grid sampling. In addition, using the maximum entropy (MaxEnt) and the GIS spatial analysis technique, the potential distribution of dominant species in the Yellow River Delta and their major environmental variables and ecological parameters were quantitatively analyzed. The results showed that the dominant species of the coastal wetland were Tamarix chinensis, Phragmites australis and Suaeda salsa in the Yellow River Delta.

[Evolution process and related driving mechanisms of Yellow River Delta since the diversion of Yellow River].

Based on the 23 sheets of remote sensing images from 1976 to 2009, in combining with the water and sediment data from Lijin station and the annual precipitation data of Yellow River Basin from 1976 to 2008, this paper quantitatively analyzed the features of water and sediment discharge from Yellow River, and the evolution process of Yellow River Delta and related driving mechanisms. In 1976-2008, the annual runoff and the annual sediment discharge into sea changed largely and frequently, but overall, presented a decreasing trend. Since the course of the Yellow River changed its direction to Qingshui channel in 1976, the Delta coastline and area were generally in a silting-up state.
