CONCLUSION The polysomnographic (PSG) effects of nasal surgery on positional obstructive sleep apnea/hypopnea syndrome (OSAHS) patients (PPs) and non-positional OSAHS patients (NPPs) were different. OBJECTIVE We aimed to determine the PSG data changes after nasal surgery and evaluate the PSG effect of nasal surgery on PPs and NPPs, respectively. METHODS(More)
Our purpose is to simulate the airflow inside the healthy Chinese nose with normal nasal structure and function by computational fluid dynamics (CFD) method and to analyze the relationship between the airflow and physiological function. In this study, we used the software MIMICS 13.0 to construct 20 3-dimensional (3-D) models based on the computer(More)
BACKGROUND Aberrant epithelial repair has been observed in chronic rhinosinusitis (CRS) patients; however, the mechanism of epithelial cell repair regulation is unclear. Epidermal growth factor (EGF) plays an important role in regulating epithelial cell repair in lower airway and may be a critical factor in the remodeling processes of CRS. The objective of(More)
CONCLUSIONS Computational fluid dynamics (CFD) methods can provide detailed information on airflow characteristics in models of septal deviation. Different locations of septal deviation lead to variation of nasal airflow. Both the location of the septal deviation and the inferior turbinate hypertrophy in the concave side may play an important role in(More)
BACKGROUND Chronic rhinosinusitis (CRS) without nasal polyps (CRSsNP) and with nasal polyps (CRSwNP) is reported to involve different inflammatory processes in sinonasal mucosa and bone tissue, and these processes remain uncharacterized. OBJECTIVE We aimed to investigate the molecular mechanisms of osteitis in Chinese patients with CRS to better(More)
Background. Eosinophilic angiocentric fibrosis (EAF) is a rare benign condition of unknown aetiology that causes stenosis of the upper respiratory tract. It is most commonly found at the nasal septum and sinus mucosa causing mucosal thickening and nasal obstructive symptoms. The diagnosis is mainly based on characteristic histologic findings. Case Report. A(More)
UNLABELLED The modified septoplasty with three tension lines resection is an effective and well-tolerated procedure, which can improve the objective and subjective outcomes, and provide a good approach that is applicable for various septal deviations, especially caudal deviation. OBJECTIVES According to the biomechanics of the septal deviation, a modified(More)
OBJECTIVES The aim of this study is to look at the incidence of supraorbital ethmoid cells (SOEC) in normal Chinese subjects by using spiral computed tomography (CT) scanning. In addition, subjects with chronic rhinosinusitis with SOEC were reviewed for endoscopic analysis. METHODS A total of 202 normal Chinese subjects underwent spiral CT. Meanwhile, a(More)
UNLABELLED Japanese encephalitis virus (JEV) is a typical mosquito-borne flavivirus responsible for acute encephalitis and meningitis in humans. However, the molecular mechanism for JEV pathogenesis is still unclear. MicroRNAs (miRNAs) are small noncoding RNAs that act as gene regulators. They are directly or indirectly involved in many cellular functions(More)
