Analysis of pathogenetic process of fungal rhinosinusitis: Report of two cases.

Background: Fungal rhinosinusitis is an infectious and/or allergic disease caused by fungi in the sinus and nasal cavity. Due to the warm and humid climate in Guangxi Zhuang Autonomous Region, the incidence of fungal rhinosinusitis is higher than that in other provinces. However, its physiological mechanism is not yet clear.

[The effect of intranasal steroid on nasal mucosa in rat model of allergic rhinitis].

Objective: To investigate the effects of intranasal steroid on nasal mucosa in rat model of allergic rhinitis (AR).

Method: Thirty-six SD rats were randomly divided into three groups (each included 12 rats): the intranasal steroid group(group A),the allergic rhinitis group(group B) and the normal control group(group C). AR model was reproduced by ovalbumin in group A and B.

Plasmonic rainbow rings induced by white radial polarization.

This Letter presents a scheme to embed both angular/spectral surface plasmon resonance (SPR) in a unique far-field rainbow feature by tightly focusing (effective NA=1.45) a polychromatic radially polarized beam on an Au (20 nm)/SiO2 (500 nm)/Au (20 nm) sandwich structure. Without the need for angular or spectral scanning, the virtual spectral probe snapshots a wide operation range (n=1-1.

[Clinical application of incomplete tympanectomy for secretory otitis media in nasopharyngeal carcinoma after radiotherapy].

Background & Objective: Efficacy of previous treatments on secretory otitis media ears with severely damaged eustachian tube function after radiotherapy is limited. Tympan perforation can avoid relapse of secretory otitis media. This study was to explore clinical value of incomplete tympanectomy for secretory otitis media in patients with nasopharyngeal carcinoma (NPC) after radiotherapy.

[Application of floating tube in dilation of eustachian tube under nasal endoscopy to treat post-irradiation secretory otitis media].

Objective: To analyse the function of eustachian tube in post-irradiation secretory otitis media and investigate the curative effect of dilating eustachian tube with Swan-Gans thermodilution catheter for treating post-irradiation secretory otitis media in NPC patients.

Method: Twenty-one (37 ears) post-irradiation secretory otitis media patients with NPC were selected in this study, by using eustachian tube function synthetic inspection facility (JK-04A model), the eustachian tube function was examined, and the obstructive eustachian tube was dilated with Swan-Gans thermodilution catheter under nasal endoscopy.

Result: The eustachian tube function in 37 ears with post-irradiation secretory otitis media reveals normal, obstructive, insufficiency and opening model was 2, 21, 8, and 6 respectively.
