CONCLUSIONS
The study suggests that cancerous inhibitor of protein phosphatase 2A (CIP2A) expression and eosinophilia associate with chronic rhinosinusitis with nasal polyps with aspirin exacerbated respiratory disease (CRSwNP + AERD). Further studies with a larger sample size are needed to evaluate
The overlying inflammatory mucosa plays a crucial role in the initiation of osteitis; however, the molecular mechanism is unclear. The objective of this study was to explore the bone morphogenetic protein (BMP) pathway and to correlate the expression of key signaling molecules with the BACKGROUND
Current evidence suggests that membrane-tethered mucins could mediate corticosteroid efficacy, interacting with glucocorticoid receptor (GR) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Mucin 4 (MUC4)-tethered mucin is expressed in nasal polyp (NP) epithelial cells
BACKGROUND The aim of this study was to explore the upregulated nuclear factor kappaB (NF-kappaB)/microRNA-155 (miR-155) in regulating inflammatory responses and relapse of chronic rhinosinusitis (CRS) with nasal polyps (NP), which underlies the molecular mechanism of glucocorticoid treatment.
OBJECTIVE
To explore the pathogenesis of nasal polyposis and the expression of transforming growth factor beta (TGF-beta) in human inflammatory nasal polyps.
METHODS
TGF-beta 1-3 in nasal polyp tissues and inferior turbinate mucosa of twenty-five polyposis patients were detected with
BACKGROUND
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic inflammatory disease of the upper airways frequently associated with asthma. Bacterial infection is a feature of CRSwNP that can aggravate the disease and the response to glucocorticoid treatment.
OBJECTIVE
We examined whether
BACKGROUND
A number of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) are resistant to oral corticosteroids. Mucin 1 (MUC1) shows anti-inflammatory properties, and its cytoplasmic tail (CT) interacts with transcription factors, facilitating their nuclear translocation. Because
OBJECTIVE
To identify genes whose expression is most characteristic of chronic rhinosinusitis and aspirin-sensitive asthma through genome-wide transcriptional profiling of nasal polyp tissue.
METHODS
Prospective, controlled study conducted at a tertiary care institution.
METHODS
Thirty genome-wide
Betamethasone topical nasal drops may have systemic corticosteroid activity and cause suppression of the hypothalamo-pituitary-adrenal (HPA) axis and impairment of bone turnover. The aim of this study was to assess the effect of a standard 6-week regime of betamethasone topical nasal drops on the
OBJECTIVE
Interleukin-22 (IL-22), mainly produced by CD4+ T-helper subtypes and innate lymphoid cells at barrier surfaces, is found to involve in several diseases, including diabetes, rheumatoid arthritis, peri-implantitis and chronic rhinosinusitis with nasal polyps. The purpose of this study was
Tumor-induced osteomalacia (TIO) is a rare, paraneoplastic syndrome featured with fibroblast growth factor 23 (FGF23) secretion primarily by benign mesenchymal tumors and sometimes by malignancies. TIO diagnosis and treatment is often delayed because TIO usually has nonspecific OBJECTIVE
The pathogenesis of tympanosclerosis is unclear. The study was performed to investigate the role of nitric oxide, free oxygen radicals, and antioxidants in development of tympanosclerosis in patients with chronic otitis media.
METHODS
A prospective study in patients with nasal
alpha 1-Adrenergic (alpha 1-AR) agents stimulate NaCl(K) cotransport and phosphatidylinositol-4,5-bisphosphate [PtdIns(4,5)P2]-specific phospholipase C in human trachea and nasal polyp epithelial cells. One second messenger generated by PtdIns(4,5)P2 degradation is inositol trisphosphate. We now
Nasal inverted papilloma is a rare benign tumor of epithelial origin with aggressive evolution, bone destruction, recurrence, and malignant transformation. Msx2 is a homeobox gene implicated in organ development, bone metabolism, and tumorigenesis. Using reverse transcriptase-polymerase chain
Objective:To analyze the clinical significance of phosphatase of regenerating liver-3(PRL-3) and vascular endothelial growth factor(VEGF)expression in sinonasal squamous cell carcinomas.Method:We use immunohistochemical analysis and RT-PCR to detecte the expression of PRL-3 and VEGF protein in 62
