Application value of central venous-arterial carbon dioxide partial pressure difference in postoperative cognitive dysfunction in patients with acute aortic dissection.

Objective: This study aims to investigate the clinical application value of the central venous-arterial carbon dioxide partial pressure difference (Pv-aCO2) in postoperative cognitive dysfunction(POCD) in patients with acute aortic dissection.

Methods: A retrospective analysis was conducted on the general data of 236 patients. Blood gas samples were collected from the arterial and venous lines at various time points during the surgery, including before and after the initiation of cardiopulmonary bypass (CPB), immediately after CPB initiation, before and after deep hypothermic circulatory arrest, 30 min after rewarming, and 5 min before weaning from CPB.

Intraoperative central venous pressure during cardiopulmonary bypass is an alternative indicator for early prediction of acute kidney injury in adult cardiac surgery.

Background: The relationship between venous congestion in cardiopulmonary bypass (CPB) and acute kidney injury (AKI) in cardiac surgery has not utterly substantiated. This study aimed at investigate the relationship between CVP in CPB and the occurrence of AKI.

Methods: We retrospectively reviewed 2048 consecutive patients with cardiovascular disease undergoing cardiac procedure with CPB from January 2018 to December 2022.

Nuclear Factor Erythroid 2-Related Factor 2 is Essential for Low-Normobaric Oxygen Treatment-Mediated Blood-Brain Barrier Protection Following Ischemic Stroke.

Cerebral ischemia/reperfusion (I/R) injury increases blood-brain barrier (BBB) permeability, leading to hemorrhagic transformation and brain edema. Normobaric oxygen (NBO) is a routine clinical treatment strategy for this condition. However, its neuroprotective effects remain controversial.

Effect of a group-based acceptance and commitment therapy (ACT) intervention on self-esteem and psychological flexibility in patients with schizophrenia in remission.

The present study explored whether acceptance and commitment therapy (ACT), a cognitive behavioral therapy approach, could improve the symptoms of schizophrenia spectrum disorders among patients with schizophrenia in remission. A pre- and post-treatment design with two evaluation time points was employed. Sixty outpatients with schizophrenia in remission were randomly divided into two groups: the ACT plus treatment as usual (ACT+TAU) and treatment as usual (TAU) groups.

Thalassiosira weissflogii grown in various Zn levels shows different ecophysiological responses to seawater acidification.

The heterogeneity of Ni bioavailability and toxicity of Prorocentrum donghaiense influenced by DOM fractions incubated in urea was investigated in this study. On the occasion, chlorophyll (Chl a) concentration, growth rate, and photosynthesis parameters were monitored to track changes occurring in the test organism.

Facile Synthesis of Monodispersed Titanium Nitride Quantum Dots for Harmonic Mode-Locking Generation in an Ultrafast Fiber Laser.

As a member of the transition metal nitride material family, titanium nitride (TiN) quantum dots (QDs) have attracted great attention in optical and electronic fields because of their excellent optoelectronic properties and favorable stability. Herein, TiN QDs were synthesized and served as a saturable absorber (SA) for an ultrafast fiber laser. Due to the strong nonlinear optical absorption characteristics with a modulation depth of ~33%, the typical fundamental mode-locked pulses and harmonics mode-locked pulses can be easily obtained in an ultrafast erbium-doped fiber laser with a TiN-QD SA.

A study of soil seed banks across one complete chronosequence of secondary succession in a karst landscape.

Anthropogenic disturbance and distinctive geochemistry have resulted in rocky desertification in many karst regions of the world. Seed banks are crucial to vegetation regeneration in degraded karst ecosystems characterized by a discontinuous distribution of soil and seasonal drought stress. However, the dynamics of seed banks across one complete series of secondary succession and the underlying mechanisms remain unclear.

Characteristics and surgical invervention of ovarian torsion in pregnant compared with nonpregnant women.

The aim of our study was to compare the clinical and surgical characteristics of pregnant and nonpregnant women with surgically verified ovarian torsion, as well as the differences among 3 trimesters during pregnancy.We conducted a retrospective study of patients diagnosed with surgically proven ovarian torsion in our hospital from January 2012 to June 2018. The clinical characteristics, surgical procedure, pathologic outcomes, and trimesters of pregnancy were analyzed.

Dynamics of nitrogen, phosphorus, and organic pollutant losses from a small watershed in the drinking-water source protection area in Guiyang City of Southern China.

Nutrients in runoff degrade water quality. The development of schemes to mitigate such degradation requires a characterization of the underlying dynamic processes of nutrient loss. The drinking-water source protection area in the Lake Hongfeng watershed of Guiyang City, the capital of Guizhou Province, China, has been delimited for effective conservation.

Effects of root exudates of woody species on the soil anti-erodibility in the rhizosphere in a karst region, China.

Introduction: Rhizospheres, the most active interfaces between plants and soils, play a central role in the long-term maintenance of the biosphere. The anti-erodibility of soils (AES) regulated by the root exudates is crucial to the soil stability in the rhizospheres. However, scientists still debate (1) the key organic matter of the root exudates affecting the AES and (2) the interspecific variation of these root exudates.

[Accumulation and Biotransformation in Typical Freshwater Algae Species Influenced by Titanium Dioxide Nanoparticles Under Long-term Exposure].

In the present study, the accumulation and biotransformation of arsenate in typical freshwater algae species were examined under long-term influence of titanium dioxide nanoparticles (nano-TiO).

Sinonasal intravascular papillary endothelial hyperplasia successfully treated by endoscopic excision: a case report and review of the literature.

Background: Intravascular papillary endothelial hyperplasia (IPEH) is an abundant, usually intravascular, benign endothelial proliferation that may mimic angiosarcoma clinically and histopathologically. Its occurrence in the sinonasal cavity is extremely rare. To the best of our knowledge, we present the first case with the most extensive IPEH ever found within the sinonasal cavity.

[Dynamic principle of ecosystem restoration based on plant diversity].

The dynamics of ecosystem restoration is an important issue in ecology. Based on the theories of island biogeography, plant community succession, biodiversity sustaining mechanism and ecosystem function, a dynamic model of ecosystem restoration was deduced, and verified by the observation data on semi-humid evergreen broadleaved forest at its secondary succession phase. The dynamic principle was discussed based on the analysis of the nature of the dynamic model.
