Sarcomatoid carcinoma is a rare disease, while larynx sarcomatoid carcinoma is a rarer type of cancer characterized by high malignancy and rapid growth. This type of cancer is prone to misdiagnosis and recurrence. The present case study aimed to provide a detailed report on the diagnosis and treatment of a male patient who underwent three tumor resections in the same location of the vocal cords within a short time.

We need to try to replace it with more non-invasive and effective treatments. The 2014 guidelines of the American Academy of Otolaryngology-Head and Neck Surgery recommend the use of cognitive behavioral therapy (CBT) to treat tinnitus.

After exposure, Cd accumulates in the inner ear and induces spiral ganglion neuron (SGN) degeneration; however, the underlying mechanisms are poorly understood. Dysfunctional autophagy has been implicated in many neurodegenerative diseases, including Cd-induced neurotoxicity.

To investigate the relationship between Helicobacter pylori(H.pylori) infection and laryngeal lesions. 204 patients with laryngeal lesions were arranged into laryngeal lesions group, and 150 healthy persons who were willing to accept the electronic fiber gastroscopy examination in the same period were selected as control group.

Nasopharyngeal carcinoma (NPC) is a common cancer in southern China and Southeast Asia. Nowadays, radiotherapy is the therapy of choice for NPC patients, and chemotherapy has been found as an alternative treatment for advanced NPC patients. However, finding novel drugs and pharmacologically therapeutic targets for NPC patients is still urgent and beneficial.

However, in numerous families with hearing loss, the specific gene mutation remains to be identified. In the present study, the clinical characteristics and gene mutations were analyzed in a Chinese pedigree with hereditary hearing loss.

The possible relationship between age-related hearing loss and G9a expression in the auditory cortex has not been fully explored. This study aimed to understand the expression patterns of G9a-mediated histone methylations in the auditory cortex during aging.

Methods: This multicenter cross-sectional survey began at the different institutions ranged from July to October 2017, and the duration was 12 months. A total of 90,440 eligible patients were finally enrolled from 72 medical institutions in China.
Conclusion: Scopolamine, a tropane alkaloid drug that mainly acts as an antagonist of muscarinic acetylcholine receptors, was found to reduce the local field potentials (LFP) of auditory cortex (AC) evoked by tone and gap-offsets whose effects may compensate the cortical hyperexcitability related to tinnitus.
Objective: To study the effects of scopolamine on the AC and the inferior colliculus (IC) of awake rats in order to understand scopolamine's effect on tinnitus and gap detection.
Method: Silent gaps (duration varied from 2-100 ms) embedded in otherwise continuous noise were used to elicit AC and IC response.

Objective: To investigate the histological changes in the vestibular endorgans of Smad4 gene conditional knockout mice and to explore the influence of the Smad4 gene on vestibular development.
Methods: Histological changes of periphery vestibular organs in inner ear of Smad4 conditional knockout mice were investigated by frozen sections, immunofluorescence, confocal microscopy, scanning electron microscopy and transmission electron microscopy.
Results: There was no Smad4 expression in the inner ear cartilage capsule of Smad4-/- mice.
Hyperacusis, a marked intolerance to normal environmental sound, is a common symptom in patients with tinnitus, Williams syndrome, autism, and other neurologic diseases. It has been suggested that an imbalance of excitation and inhibition in the central auditory system (CAS) may play an important role in hyperacusis. Recent studies found that noise exposure, one of the most common causes of hearing loss and tinnitus, can increase the auditory cortex (AC) response, presumably by increasing the gain of the AC.

This retrospective study included 177 cases with benign space-occupying lesions of the orbital and sinus resected between 2001 and 2009. Locations of lesions were assigned to 3 anatomic categories.

We reported previously that small mothers against decapentaplegic homolog-4 (Smad4) is required for inner ear cochlear development and normal auditory function in mammals; however, the distribution and functional mechanisms of Smad4 at various stages of vestibular development remained unclear. To investigate the relationship between the Smad4 gene and vestibular organ development, we measured changes in the expression of BMP4 and Smad4 during vestibular development in C57BL/6 mice.

However, whether sensorineural hearing loss would affect central auditory processing is not clear. Recent studies found that salicylate not only affects outer hair cell motility in the cochlea, but also blocks GABAergic neuron activities in central nervous systems.

Objective: To explore the distributing and changes of nitric oxide (NO) and calcitonin gene-related peptide (CGRP) in obstructive sleep apnea and hypopnea syndrome (OSAHS).
Methods: This study investigated the content of NO and CGRP in plasma and in pharyngeal tissues of OSAHS subjects. Moreover, the distribution of NOS and CGRP in pharyngeal tissues was researched using method of immunohistochemistry.
