Objective:In order to ascertain the lateral operation and medial maxillectomy affect on nasal airway.Method:Report 16 cases of nasal cavity or nasal sinus neoplasm who were therapied by lateral rhinotomy and medial maxillectomy.They were observed by acoustic rhinometer (AR) and CT examination in 1～2.5 years after the surgery. Result:The feeling of nasal obstruct were disappeared in 3 months after the surgery. The nasal airway resistance(NAR) of the ill nasal cavity was markedly decreased after the surgery, and the total NAR were decreasing unmarkably. The mucous proliferation was notable only in the first year after surgery, and especially on remains of the inferior turbinate or extra wall of nasal cavity.Conclusion:Lateral rhinotomy operation and medial maxillectomy have less impact on nasal airway and the functions.

Objective To explore the exercise induced immunity changes during incremental load training from the view of the expression of helper T cells (Th) mRNA. Methods Using the technique of real-time quantified PCR to observe T-helper-special cytokine mRNA of peripheral blood mononuclear cell dynamically in healthy young male who have been trained with incremental exercise for five weeks. Results There was no obvious change in IL-2 mRNA during five weeks training. Meanwhile IL-4 mRNA increased greatly in the second, third and fourth week. IFN-? mRNA as well as IFN-? mRNA/IL-4 mRNA increased remarkably in the third, fourth and fifth week . Conclusion The expression of T-helper1/ T-helper2 cytokine mRNA were up-regulated after five weeks and the subjects were gradually adapt to the increased load which indicated the enhancement of immunity function .

AIM: To study the allergic disease in recurrent tonsillitis. METHODS: Immunohistochemical technique was used to investigate interleukin-4(IL-4) production in tonsil. RESULTS:The result showed that: a higher incidence of IL-4 producing cells were found in the tonsils of all ages, and a high density of IL-4 was found in the reticular crypt epithelium and extrafollicular, but low density in germinalcenter. IL-4 has been shown play a crucial role in the pathogensis of allergic disease. CONCLUSION:Allergic disease is an important reason of recurrent tonsillitis. The conclusion will give a new way to cure recurrent tonsillitis.
