SIRT5 exacerbates eosinophilic chronic rhinosinusitis by promoting polarization of M2 macrophage.

Background: Previous studies implied that local M2 polarization of macrophage promoted mucosal edema and exacerbated T2 type inflammation in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the specific pathogenic role of M2 macrophages and the intrinsic regulators in the development of CRS remains elusive.

Objective: We sought to investigate the regulatory role of SIRT5 in the polarization of M2 macrophages and its potential contribution to the development of CRSwNP.

Cisplatin attenuates taste cell homeostasis and induces inflammatory activation in the circumvallate papilla.

Gustation is important to several biological functions in mammals. However, chemotherapy drugs often harm taste perception in cancer patients, while the underlying mechanism is still unclear for most drugs and there is no effective way to restore taste function. This study investigated the effects of cisplatin on the taste cell homeostasis and gustatory function.

A Systematic Review and Meta-analysis of the Effects of Topical Tranexamic Acid Topical Vasoconstrictors on the Management of Epistaxis.

Objective: We aimed to evaluate the effectiveness of topical tranexamic acid (TXA) versus topical vasoconstrictors in the management of epistaxis via a systematic review and meta-analysis.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards were followed for the meta-analysis. We systematically searched Embase, Web of Science, Cochrane Library, CNKI, and PubMed for randomized controlled trials (from inception to August 2022; no language restrictions), comparing the effect of topical TXA and topical vasoconstrictors on the treatment of epistaxis.

Profiling of the chemical space on the phenyl group of substituted benzothiazole RIPK3 inhibitors.

Necroptosis is confirmed as a precisely programmed cell death that is activated in caspase-deficient conditions. Receptor-interacting protein kinase 1 (RIPK1), RIPK3 and mixed-lineage kinase domain-like pseudokinase (MLKL) are the key regulators involved in the signaling pathway. However, accumulating evidence suggests that RIPK1 also works in apoptosis and inflammation pathways independent of necroptosis.

Multidisciplinary Team in Severe Infectious Complications Caused by Pharyngeal Foreign Body.

Background: Pharyngeal foreign body is not only a common emergency in people's daily life, but also a common simple disease in otorhinolaryngology. However, the disease is easy to be ignored due to its common occurrence, which may lead to a series of serious complications including sepsis and local abscess.

Case Presentation: In this case, a patient with sepsis, piriform fistula, deep neck abscess, and mediastinal abscess caused by a fishbone was reported.

Associations between sleep disorders and anxiety in patients with tinnitus: A cross-sectional study.

Objective: To investigate the characteristics of sleep disorders and anxiety in patients with tinnitus, their influencing factors, and the role of sleep disorders as mediators.

Methods: The general conditions and disease characteristics of 393 patients with tinnitus presented to the Changzheng Hospital of the Naval Medical University from 2018 to 2021 were collected. All patients accepted questionnaires such as Tinnitus Handicap Inventory (THI), Pittsburgh Sleep Quality Index (PSQI) and Self-rating Anxiety Scale (SAS), and then the characteristics and the influencing factors of sleep disorders and anxiety were analyzed.

Retropharyngeal Abscess in an Adult With Pneumonia During COVID-19 Outbreak.

Background: Retropharyngeal abscesses are rarely reported in adults and occur mostly in patients with immunocompromised or as a foreign body complication. Admittedly, the treatment of retropharyngeal abscesses frequently involves surgical drainage to achieve the best results. However, when retropharyngeal abscesses occurred in a highly suspected patient with COVID-19, the managements and treatments should be caution to prevent the spread of the virus.

Association between alpha-synuclein (SNCA) rs11931074 variability and susceptibility to Parkinson's disease: an updated meta-analysis of 41,811 patients.

Background And Objectives: Parkinson's disease (PD) is one of the most common forms of neurodegenerative disorders, and its etiology remains unclear. Single nucleotide polymorphisms (SNPs) of alpha-synuclein (SNCA) have been found to be significantly associated with PD risk. In particular, the variant rs11931074 was found in one meta-analysis to appear to play a role in the occurrence of PD.

NLRP3 inflammasome activation promotes the development of allergic rhinitis via epithelium pyroptosis.

Allergic rhinitis (AR) is a worldwide highly prevalent nasal inflammatory disease with elusive mechanisms about the regulation of innate immune response. The roles and mechanisms of NLRP3, a typical inflammasome, in AR development remain unclear. Here we investigate the roles of NLRP3 inflammasome activation in the development and progression of AR and try to uncover its potential mechanisms underlying.

Construction of an irreversible allergic rhinitis-induced olfactory loss mouse model.

Clinical data show that part of patients with sinonasal diseases suffered from olfactory dysfunction, especially with allergic rhinitis (AR) and chronic rhinosinusitis (CRS). However, the mechanisms responsible for AR-induced olfactory loss are still largely unknown. Because of the difficulty to obtain human olfactory mucosa, an AR-induced olfactory loss animal model needs to be constructed to clarify the mechanism.
