Contribution of nebulized budesonide before bronchoscopy, a prospective clinical study.

Purpose: This study evaluated the efficacy of adding budesonide to nebulized lidocaine in patients undergoing flexible bronchoscopy (FB) under topical anaesthesia.

Study Design: Patients aged ≥18 years, scheduled for FB under topical anaesthesia were randomized into two groups: the combination group received a pre-treatment of 2 ml 1 mg budesonide with 5 ml 2% lidocaine, whilst the lidocaine group received 5 ml 2% lidocaine with 2 ml saline solution, both administered via nebulization. Blood pressure (BP), heart rate, and percutaneous oxygen saturation were recorded before, during, and 10 min after FB.

Fluid volume status detection model for patients with heart failure based on machine learning methods.

Backgroud: Fluid volume abnormalities are a major cause of exacerbations in heart failure patients. However, there is few efficient, rapid, or cost-effective clinical approach for determining volume status, resulting in inadequate or unsatisfactory treatment. The aim was to develop an early fluid volume detection model for heart failure patients utilizing a machine learning stratification.

The gut-brain axis underlying hepatic encephalopathy in liver cirrhosis.

Up to 50-70% of patients with liver cirrhosis develop hepatic encephalopathy (HE), which is closely related to gut microbiota dysbiosis, with an unclear mechanism. Here, by constructing gut-brain modules to assess bacterial neurotoxins from metagenomic datasets, we found that phenylalanine decarboxylase (PDC) genes, mainly from Ruminococcus gnavus, increased approximately tenfold in patients with cirrhosis and higher in patients with HE. Cirrhotic, not healthy, mice colonized with R.

Secretory breast carcinoma: a multicenter clinicopathologic study of 80 cases with emphasis on prognostic analysis and chemotherapy benefit.

Purpose: To investigate clinicopathologic characteristics and prognosis in secretory breast carcinoma (SBC) and to determine chemotherapy benefits stratified by different subgroups.

Methods: SBCs and triple-negative invasive ductal carcinoma patients (TN-IDCs) were enrolled from three cancer centers between January 2011 and December 2020. SBCs were further divided into two subgroups: those with triple negativity (TN-SBCs) and those without (non-TN-SBCs).

derived exosome-like nanovesicles alleviate restenosis after vascular injury through the Keap1/Nrf2 pathway.

Despite the significant alleviation of clinical cardiovascular diseases through appropriate interventional treatments, the recurrence of vascular restenosis necessitating reoperation remains a substantial challenge impacting patient prognosis. Plant-derived exosome-like nanovesicles (PELNs) are integral to interspecies cellular communication, with their functions and potential applications garnering significant attention from the research community. This study extracted -derived exosome-like nanovesicles (SL-ELNs) and demonstrated their inhibition of PDGF-BB-induced proliferation, migration, and phenotypic transformation of vascular smooth muscle cells (VSMCs).

Unlocking lung regeneration: insights into progenitor cell dynamics and metabolic control.

Regenerative responses are particularly important in the lungs, which are critical for gas exchange and frequently challenged by environmental insults. The lung progenitor cells play a central role in the lung regeneration response, and their dysfunction is associated with various lung diseases. Understanding the mechanisms regulating lung progenitor cell function is essential for developing new therapeutic approaches to promote lung regeneration.

Bile acid derivatives from gut microbiota promote GBPs-mediated activation of caspase-4/11 by LPS through .

Lipopolysaccharide (LPS) mediated caspases-4 (humans) and caspase-11 (rodent) (caspase-4/11) signaling can cause maturation of inflammatory cytokine IL-1β and cellular pyroptosis in the macrophages through guanylate-binding proteins (GBPs). However, how caspase-4/11s bind with GBPs together to activate caspase-4/11 by LPS remains elusive. We here found that BA derivatives from gut microbiota can regulate sensitivity of macrophages to LPS and Gram-negative bacteria through .

Modified CD15/CD16-CLL1 inhibitory CAR-T cells for mitigating granulocytopenia toxicities in the treatment of acute myeloid leukemia.

CLL1 Chimeric antigen receptor T-cell (CAR-T) therapy, as a promising immunotherapeutic approach, has demonstrated its potential to enhance the prognosis of patients diagnosed with acute myeloid leukemia (AML). However, due to the overexpression of CLL1 on neutrophils, CAR-T cells not only eliminated tumor cells but also eradicated neutrophils simultaneously, resulting in severe granulocytopenia and subsequent infections. Considering the distinct expression levels of CD15/CD16 on neutrophils and AML blasts, we have devised novel modified CD15 /CD16-CLL1 iCAR structures incorporating diverse inhibitory elements.

Knockdown of RUVBL2 improves hnRNPA2/B1-stress granules dynamics to inhibit perioperative neurocognitive disorders in aged mild cognitive impairment rats.

Perioperative neurocognitive disorders (PND) is common in aged mild cognitive impairment (MCI) patients and can accelerate the progression to dementia. This process involves heterogeneous nuclear ribonucleoprotein A2/B1 (hnRNPA2/B1)-mediated aggregates of stress granules (SGs), while RUVBL2 influences the dynamics of these SGs. Our research explored a new target for modulating hnRNAPA2/B1-SGs dynamics to accelerate their disassembly and potentially delay MCI progression due to PND.
