Advances in postoperative thyroid-stimulating hormone suppression therapy in females with thyroid cancer / 中华耳鼻咽喉头颈外科杂志

Differentiated thyroid cancer is the most common malignant carcinoma in female population.Postoperative long-term thyroid-stimulating hormone(TSH) suppression therapy can reduce the risk of recurrence for differentiated thyroid cancer and control the progress of the disease, but it also induces simultaneously subclinical hypothyroidism and imposes negative effect on female. In addition to cardiovascular disease, TSH suppression therapy can lead to the alteration of sex hormone metabolism, menstrual disorder, poor influence on pregnancy and osteoporosis. This article reviews the recent studies on postoperative TSH suppression therapy in women with thyroid cancer.

Progress of dopamine in obstructive sleep apnea hypopnea syndrome / 中华耳鼻咽喉头颈外科杂志

The etiology and pathogenesis of sleep obstructive apnea hypopnea syndrome (OSAHS) is not yet definitive, evidence shows that the dysfunction of pharyngeal nerve and the atonia of the muscle innervated by these nerve could play an important role in the progress of OSAHS. Dopamine is a neurotransmitter in the central nervous system which significantly affects the sleep-awake regulation. So far mounting evidence shows that dopamine has a potential role in the modulation of hypoglossal nucleus. The progress of dopamine in obstructive sleep apnea hypopnea syndrome is reviewed in this article.

Objective:To investigate lesion size caused by channel radiofrequency volumetric reduction of por-cine tongue base in vitro using the technique of three-dimensional reconstruction. And to evaluate safety about channel radiofrequency volumetric reduction of tongue base. Method: Eighteen fresh porcine tongues were randomly separated into six groups,and each group had three ones. The tongue bases were designed six points according to description of Powell. Tongues base were acted on 10 s and 6 level by Coblation radiofrequency system and were cut into serial freezing histological sections. These segments were sectioned at 20 μm on the injury lesion and stained with H & E. Collected 2D digital imagine of order histological sections, drawn and cut apart part of the le-sion of these sections. Images were procesed IPS and were taken three-dimensional reconstruction and statistics an-alyzes with SPSS10. 0. Result: The mean value of tongue base lesion volumes among points was (359. 5± 5. 6)mm~3 ,(364. 3±7. 0)mm~3 ,(363. 7±7. 2)mm~3, (354. 1±11. 8)mm~3, (349. 4±17. 2)mm~3 ,(353. 5±7. 9)mm~3 separately. Statistic analysis by one-way ANOVA showed that there was a insignificant difference between the groups(P>0. 05). Conclusion:These results demonstrated no significant effect lesion size in channel radiofrequency volumetric reduction in the different points of the tongue base.
