Background: Trifluoperazine (TFP) is a typical antipsychotic primarily used to treat schizophrenia. In this study, we aimed to evaluate whether TFP can be used as a therapeutic agent against nasopharyngeal carcinoma (NPC) and identify its underlying molecular mechanisms.

Methods: We used NPC-TW01, TW03, TW04, and BM to assess the anticancer effects of TFP by using cytotoxicity, wound healing, colony formation, and cell invasion assays.

Purpose: This study aimed to evaluate the correlation between nasal resistance and oxygen desaturation to better elucidate the role of nasal obstruction in the pathophysiology of obstructive sleep apnea (OSA).

Patients And Methods: Eighty-eight OSA patients aged between 22 and 77 years were enrolled in this study. Nasal resistance was measured at pressures of 75, 150, and 300 Pa, with the patients first in the seated position than in the supine position.

Background: The study aimed to evaluate the anatomical differences between positional and non-positional OSA, and to identify the potential predictors for distinguishing between these two types of OSA.

Methods: A cross-sectional study of 230 consecutive patients with OSA undergoing DISE (Drug-induced Sleep Endoscopy) was carried out at a tertiary academic medical center. The factors correlating with positional and non-positional OSA were analyzed, including clinical characteristics, polysomnography data, and DISE findings.

Introduction: Nasopharyngeal carcinoma (NPC) is a common cancer in southern China and Taiwan, and radiation therapy combined with or without chemotherapy is its mainstay treatment. Although it is highly sensitive to radiotherapy, local recurrence and distant metastasis remain difficult unsolved problems. In recent years, graphene oxide (GO) has been found to be a promising novel anticancer drug carrier.

Purpose: This study aimed to evaluate the difference of upper airway collapse between the back-up head-elevated position (a 45° upward inclination) and supine position to better elucidate the role of back-up head-elevated position in reductions of obstructive sleep apnea (OSA) severity.

Methods: From August 2016 to May 2019, 198 patients aged between 18 and 70 years were recruited in this study prospectively. Drug-induced sleep endoscopy (DISE) findings were recorded with the patients first placed in the supine position then into the back-up head-elevated position with a 45° upward inclination.

Background/purpose: The aim of this study was to determine the value of drug-induced sleep ultrasonography (DISU) for evaluating tongue base thickness (TBT) from the awake state to drug-induced sleep, to further understand the impact of dynamic changes in TBT in obstructive sleep apnoea (OSA) patients.

Methods: From May 2017 to May 2018, thirty patients with OSA were prospectively recruited. Sleep was induced with propofol via use of a target-controlled infusion (TCI) system.

Background: This study was conducted to evaluate the relationship between nasal resistance in different posture and optimal positive airway pressure (PAP) level. Other potential factors were also assessed for possible influence on PAP pressure.

Methods: Forty- three patients diagnosed with obstructive sleep apnea (OSA) were prospectively recruited in this study.

Purpose: The study aimed to determine the efficacy of multilevel surgery (hyoid myotomy and suspension with uvulopalatopharyngoplasty) and continuous positive airway pressure (CPAP) for the treatment of moderate to severe obstructive sleep apnea syndrome (OSAS) and to clarify whether our surgical protocol could be as effective as CPAP.

Methods: We conducted a case series study comparing the effects of multilevel surgery and CPAP in the same subjects to minimize the influence of confounding factors. Fifteen subjects were enrolled with a pretreatment apnea-hypopnea index (AHI) ≥ 15.

Background Thiostrepton, a natural antibiotic, has recently been shown to be a potential anticancer drug for certain cancers, but its study in nasopharyngeal carcinoma (NPC) is still limited. The aims of this study were to investigate the anticancer effect of thiostrepton on NPC cells and to explore its underlying mechanism. Methods The effects of thiostrepton on the proliferation, migration, and invasion of NPC cells were investigated by a WST-1 assay, wound healing assay, and cell invasion assay, respectively.
