BACKGROUND Patients with chronic rhinosinusitis (CRS) often remain symptomatic after technically proficient functional endoscopic sinus surgery. Current hypothesis indicates biofilms may contribute to the persistence of infection. However, few studies showed biofilms in postoperative patients. This study was designed to identify bacterial biofilms on(More)
MicroRNAs (miRNAs) are small non-coding RNAs that play important roles in regulating the host immune response. Here we found that miR-22 is induced in glial cells upon stimulation with poly(I:C). Overexpression of miR-22 in the cultured cells resulted in decreased activity of interferon regulatory factor-3 and nuclear factor-kappa B, which in turn led to(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)
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)
OBJECTIVE To study the inhibitory effect of resveratrol on growth of human laryngeal cancer cell line, Hep-2. METHOD Count cell number under microscope, MTT assay was used to determine the cell growth inhibitory rate. Soft agar colony forming experiment was performed to observe the proliferation ability, before or after resveratrol treatment. RESULT(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)
CONCLUSIONS CT and MRI are helpful to detect the precise site of the fistula, which is crucial for carrying out the repair, and transnasal endoscopic surgery is an effective treatment for recurrent cerebrospinal fluid (CSF) rhinorrhea. OBJECTIVE To discuss the cause and treatment of recurrent CSF rhinorrhea. METHODS A retrospective study was undertaken(More)
OBJECTIVE Esthesioneuroblastoma (ENB) is an uncommon malignant tumor. During the past decade, endoscopic approaches have been gradually applied in treating skull base tumors. However, the experience in using this approach to treat ENB is still limited. Kadish staging and Dulguerov staging are common methods used for ENB staging, but it remains unclear as to(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)
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)
