Individualized PEEP titration by lung compliance during one-lung ventilation: a meta-analysis.

Background: Despite the physiological advantages of positive end-expiratory pressure (PEEP), its optimal utilization during one-lung ventilation (OLV) remains uncertain. We aimed to investigate whether individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV.

Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials until April 1, 2024, to identify published randomized controlled trials that compared individualized PEEP titration by lung compliance with fixed PEEP during OLV.

Image Captioning Based on Semantic Scenes.

With the development of artificial intelligence and deep learning technologies, image captioning has become an important research direction at the intersection of computer vision and natural language processing. The purpose of image captioning is to generate corresponding natural language descriptions by understanding the content of images. This technology has broad application prospects in fields such as image retrieval, autonomous driving, and visual question answering.

Association between driving pressure-guided ventilation and postoperative pulmonary complications in surgical patients: a meta-analysis with trial sequential analysis.

Background: Prior studies have reported inconsistent results regarding the association between driving pressure-guided ventilation and postoperative pulmonary complications (PPCs). We aimed to investigate whether driving pressure-guided ventilation is associated with a lower risk of PPCs.

Methods: We systematically searched electronic databases for RCTs comparing driving pressure-guided ventilation with conventional protective ventilation in adult surgical patients.

Cannabinoid receptor 2 alleviates sepsis-associated acute lung injury by modulating maturation of dendritic cells.

Background: Dendritic cells (DCs) play a key role in a variety of inflammatory lung diseases, but their role in sepsis-associated acute lung injury (SA-ALI) is currently not been illuminated. Cannabinoid receptor 2 (CNR2) has been reported to regulate the DCs maturation. However, whether the CNR2 in DCs contributes to therapeutic therapy for SA-ALI remain unclear.

Exosomal miR-127-5p from BMSCs alleviated sepsis-related acute lung injury by inhibiting neutrophil extracellular trap formation.

Neutrophil extracellular traps (NETs) play an important role in sepsis-related acute lung injury (ALI). Bone marrow mesenchymal stem cells (BMSCs)-derived exosomes and miRNA are becoming promising agents for the treatment of ALI. The current study aimed to elucidate the mechanism by BMSCs-derived exosomes carrying miR-127-5p inhibiting to the formation of NETs in sepsis-related ALI.

Pre-intensive care unit use of selective serotonin reuptake inhibitors and mortality in critically ill adults with mental disorders: analysis from the MIMIC-IV database.

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed drugs for mental disorders in critically ill patients. We performed a retrospective cohort study to investigate the association between pre-ICU use of SSRIs and mortality in critically ill adults with mental disorders. We identified critically ill adults with mental disorders based on the Medical Information Mart in Intensive Care-IV database.

TFAM-Mediated mitochondrial transfer of MSCs improved the permeability barrier in sepsis-associated acute lung injury.

Vascular endothelial cell barrier disruption is a hallmark of sepsis-induced acute lung injury (ALI). Mesenchymal stem cells (MSCs)-based therapy has been regarded as a promising treatment for repairing injured lungs, and mitochondrial transfer was shown to be important for the therapeutic effects of MSCs. Here we investigated the ability of MSCs to modulate endothelial barrier integrity through mitochondrial transfer in sepsis-induced ALI.

Bone mesenchymal stem cell-derived extracellular vesicles inhibit DAPK1-mediated inflammation by delivering miR-191 to macrophages.

Alveolar macrophage activation and apoptosis are vital contributors to sepsis-associated acute lung injury (ALI). However, the mechanisms of alveolar macrophage activation are yet to be clarified. Death-associated protein kinase 1 (DAPK1) is one of the potential candidates that play crucial roles in regulating alveolar macrophage inflammation.

Using Restricted Cubic Splines to Study the Trajectory of Systolic Blood Pressure in the Prognosis of Acute Myocardial Infarction.

Acute myocardial infarction (AMI) is still the most serious manifestation of coronary artery disease. Systolic blood pressure (SBP) is the best predictor of blood pressure in AMI. Thus, its influence on AMI is necessary to be explored.

[Mining and discovery for active components of "Coptidis Rhizome-Magnoliae Officinalis Cortex" based on network pharmacology].

To mine and discover the active components of " Coptidis Rhizome-Magnoliae Officinalis Cortex( C&M) " based on the network pharmacology,integrate and analyze the potential targets and mechanisms. The TCMSP database was used to screen active ingredients. TTD and Drug Bank databases were used to predict the potential targets by referring to relevant literature,and the pathway annotation technology was used to enrich and analyze the active ingredients and potential targets of " C&M".

Clinicopathological characteristics of patients with non-small-cell lung cancer who harbor EML4-ALK fusion gene: a meta-analysis.

Background: A novel fusion gene of echinoderm microtubule-associated protein-like 4 (EML4) and anaplastic lymphoma kinase (ALK) has been recently identified in non-small-cell lung cancers (NSCLCs). Patients with the EML4-ALK fusion gene demonstrate unique clinicopathological and physiological characteristics. Here we present a meta-analysis of large-scale studies to evaluate the clinicopathological characteristics of NSCLC patients harboring the EML4-ALK fusion gene.

[An experiment study of protection and treatment of Kudan granule on rats of pulmonary fibrosis induced by pinyangmycin].

Objective: To explore the protection and treatment effects of Kudan granule on rats of pulmonary fibrosis induced by pinyangmycin.

Method: In asepsis condition, rat was anaesthetized by 3.5% chloral hydrate, inserted the needle above the bifurcation of trachea and injecting 5 mg x kg(-1) pinyangmycin normal saline solution.

[Effect and mechanism of bishudiwan(BSDW) against allergy].

Objective: To investigate the effect and mechanism of BSDW on the model of allergic rhinitis and the model of guinea pigs by histamine shocking in guinea pigs.

Method: Using the model of allergic rhinitis in guinea pigs caused by 10% TDI, we observed the effect of BSDW on physiological and pathological symptoms of allergic rhinitis in guinea pigs, the effect of the levels of serum IgE and serum and nasal histamine. Using the model of guinea pigs by histamine shocking, we observed the effect of BSDW on physiological symptoms in guinea pigs.

Effects of san qi on gastric secretion and protective factors of gastric mucosa in the rat with precancerous lesion of stomach.

In the model rat with precancerous lesion of stomach induced by the combined method of insertion of a spring into the pylorus and high salt hot paste, effects of San Qi ([symbol: see text] Radix Notoginseng) on gastric secretion and protective factors of stomach were investigated. The results indicated that gastric secretion, gastric mucosal blood flow (GMBF) and aminohexose content lowered significantly, and malondialdehyde (MDA) increased significantly (P < 0.01) in the model group as compared with the normal group; after treatment with San Qi Powder for 12 weeks, both gastric secresion and GMBF increased, and MDA content decreased as compared with the negative control group (P < 0.
