Effect of early olfactory training on olfactory recovery after nasal endoscopy in patients with chronic rhinosinusitis and olfactory impairment.

Objective: To analyze the effect of early comprehensive olfactory rehabilitation training on olfactory recovery after nasal endoscopy in patients with chronic rhinosinusitis and olfactory impairment.

Methods: A retrospective study was conducted on 67 patients with chronic rhinosinusitis combined with olfactory impairment in our hospital from July 2018 to August 2020. Patients were divided into control group and observation group according to the time of implementing comprehensive olfactory rehabilitation training.

Long non-coding RNA HOXA11 antisense RNA upregulates spermatogenesis-associated serine-rich 2-like to enhance cisplatin resistance in laryngeal squamous cell carcinoma by suppressing microRNA-518a.

Long noncoding RNAs (LncRNAs) are closely associated with the chemoresistance of laryngeal squamous cell carcinoma (LSCC). Previous studies indicated that HOXA11-AS could function as a vital regulator in human cancers. However, the regulatory mechanisms of HOXA11-AS in the chemoresistance of LSCC remain unclear.

[Difference of upper airway variety with respiration in the sufferer of OSAHS and normal adult].

Objective: To inquiry the variety difference of upper airway caliber OSAHS sufferer and normal person in quiet respiration.

Method: Twenty OSAHS sufferer who were viewed by PSG and 16 normal adults who hagve no chief complaint of sleeping disease were selected. The curves of the subjects in a respiratory cycle were recorded by respiratory monitoring system in PSG, while the morphological changes in the pharynx of all subjects were observed by fiberscope in a calm respiratory cycle, and then both of the two processes simultaneously were recorded on the same computer.
