Tigliane glycosides from Euphorbia tirucalli as multidrug resistance modulators.

Chemical investigation of the twigs and leaves of Euphorbia tirucalli afforded six undescribed tigliane glycosides, tirucalosides A-F (1-6), together with 12 known diterpenoids (7-18). Compound 1 represents a rare carbon skeleton bearing a 5/7/5/4-fused ring system, while compound 6 contains an unusual seco-glucoside substitution. Their structures were determined by a combination of an extensive spectroscopic analysis and acid hydrolysis experiment.

Epitope-Optimized Influenza Hemagglutinin Nanoparticle Vaccine Provides Broad Cross-Reactive Immunity against H9N2 Influenza Virus.

The H9N2 avian influenza virus (AIV) represents a growing threat to the global poultry industry and poses an ongoing risk of human infections. Vaccination is a crucial strategy for the prevention and control of H9N2 AIVs. However, the continuous evolution of the virus consistently challenges the immune protection efficiency.

Multi-Omics Analysis Reveals Disturbances of Purine Metabolism and Glutamate Metabolism in the Hippocampus of Lipopolysaccharide-Induced Mouse Model of Depression.

Background: Depression is a global health concern characterized by high incidence, disability, and disease burden. Neuroimmunity, through the secretion of inflammatory mediators and mediation of neuroinflammation, plays a significant role in depression's pathogenesis. However, the underlying molecular mechanisms remain poorly understood.

Naturally Occurring Cleistanthane Diterpenoids and Their Biological Activities.

Cleistanthane diterpenoids, an important class of active natural products, are characterized by a 6/6/6 tricycle system and contain a variety of functional groups. Studies have shown that cleistanthane diterpenoids are widespread in various higher plants and endophytic fungi and exhibit a wide range of biological activities. This review provides extensive coverage of naturally occurring cleistanthane diterpenoids discovered from 1973 to 2024 and sheds light on the sources, structures, biological effects, and primary molecular mechanisms of them and provides a useful reference for the further study and development of these compounds.

Application of alkaline phosphatase-to-hemoglobin and lactate dehydrogenase-to-hemoglobin ratios as novel noninvasive indices for predicting severe acute pancreatitis in patients.

Preventing the progression of acute pancreatitis (AP) to severe acute pancreatitis (SAP) is crucial for AP patients. The use of clinical parameters in laboratory facilities for predicting SAP can be rapid, efficient, and cost-effective. This study aimed to investigate the predictive and prognostic value of collected clinical detection parameters, such as serum alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) levels, and their ratios, such as ALP-to-hemoglobin (Hb) and LDH-to-Hb ratios, for the prediction of SAP occurrence, complications, and mortality.

Evaluation of the Correlation Between Nasal Secretion ECP-MPO Test Papers and Immune Markers in Subcutaneous Immunotherapy of Dust Mites.

Purpose: Up to now, there is no generally accepted biomarker to indicate the clinical response of immunotherapy. This study mainly analyzed the correlation between eosinophil cationic protein-myeloperoxidase (ECP-MPO) test papers and other immunotherapy indices in subcutaneous immunotherapy of dust mites and to explore whether the test paper can be used as an auxiliary index to quickly evaluate the efficacy of immunotherapy.

Patients And Methods: This study included 53 participants who received subcutaneous immunotherapy at the allergy clinic of Renmin Hospital of Wuhan University and 28 control participants.

[Expert consensus on the diagnosis and treatment of respiratory diseases exacerbated by nonsteroidal anti-inflammatory drugs （2024, Chengdu）].

Non-steroidal anti-inflammatory drugs-exacerbated respiratory disease （N-ERD） is a chronic respiratory disease characterized by eosinophilic inflammation, featuring chronic rhinosinusitis （CRS）, asthma, and intolerance to cyclooxygenase 1 （COX-1） inhibitors. The use of these medications can lead to an acute worsening of rhinitis and asthma symptoms. This condition has not yet received sufficient attention in China, with a high rate of misdiagnosis and a lack of related research.

Chinese Expert Consensus on the Use of Biologics in Patients with Chronic Rhinosinusitis (2022, Zhuhai).

Background: Chronic rhinosinusitis (CRS) is a common inflammatory disease in otolaryngology, mainly manifested as nasal congestion, nasal discharge, facial pain/pressure, and smell disorder. CRS with nasal polyps (CRSwNP), an important phenotype of CRS, has a high recurrence rate even after receiving corticosteroids and/or functional endoscopic sinus surgery. In recent years, clinicians have focused on the application of biological agents in CRSwNP.
