Upper airway cough syndrome in 103 children.

Background: In China, upper airway cough syndrome (UACS) is only less frequent than cough-variant asthma and accounts for 24.71% of chronic cough. This study aimed to determine the pathogenetic constituents and factors affecting UACS in children of different age groups, and to identify clinical clues for diagnosing UACS and a method for curative effect evaluation.

A Preliminary Study on Sinus Fungus Ball with MicroCT and X-Ray Fluorescence Technique.

Background: Sinus fungus ball, an accumulation of fungal dense concretions, is a common disease in practice, and might cause fatal complications or lead to death once converted into invasive type. Early preoperative diagnosis of this disease can lead to appropriate treatment for patients and prevent multiple surgical procedures. Up to now, the diagnostic criteria of sinus fungus ball have been defined and computed tomography (CT) scan was considered as a valuable preoperative diagnostic tool.

[Micro-CT imaging research of acoustic capsule in mice].

Objective: To get the three-Dimensional imaging model of internal ear and middle ear using the Micro-CT equipment, and research the nondestructive imaging of mice acoustic capsule, and investigate the application of Micro-CT inmorphology of acoustic capsule.

Methods: The mice were executed to harvest the acoustic capsules. The acoustic capsules were fixed in trinitrophenol before scanning by Micro-CT .

[Clinical analyses of polysomnogram in snoring children].

Objective: To analyze the characteristics of sleep structure, heart rate and arousal index (ArI) in children with primary snoring (PS) and mild, moderate or severe obstructive sleep apnea hypopnea syndrome (OSAHS).

Methods: A total of 113 children with sleep disorders were enrolled from January 2010 to March 2012 at Affiliated Children's Hospital, Capital Institute of Pediatrics. All of them underwent polysomnogram (PSG) and the data were analyzed statistically by SPSS 19.

[Micro-CT imaging of guinea pig cochlear].

Objective: To employ micro-CT equipment for nondestructive three-dimensional (3D) imaging of internal ear.

Methods: The guinea pigs were anesthetized by napental and bilateral cochleas harvested. Cochlea was fixed in glutaraldehyde before scanning of micro-CT.

[Clinical analysis of abnormal acoustic admittance in preschool children with nasal and nasopharyngeal disorders].

Objective: To investigate the risk factors of related disorders, which could lead to potential otitis media by observing the abnormal configuration of drum and abnormal acoustic immittance without symptoms in preschool children.

Methods: Eighty-one cases (162 ears) received flexible pharyngorhinoscopy, skin prick test, CT examination of sinus, and were diagnosed as allergic rhinitis, chronic sinusitis, adenoid hypertrophy. They had no complaints of ear related symptoms, but were observed to have abnormality in ear drum by physical examined.

[Clinical analysis of normal subjects and dizzy patients with postural sway test].

Objective: To study the characteristics of the normal subjects with postural sway test and discuss the value of postural sway test in the diagnosis of dizzy patients.

Methods: Totally 112 normal subjects, 72 patients with peripheral vertigo, and 30 patients with central vertigo were examined using a stabilometer (EAB-100, Anima Co., Japan).

[Expressions of c-Fos and NADPH-d in the related brainstem during vestibular compensation].

Objective: To study the mechanism of vestibular compensation and to observe the changes of c-Fos and NADPH-d expressions in the brainstem of the vestibular deafferentation rats in static status or following angular acceleration stimulation.

Methods: Totally 60 SD rats were randomly divided into control group (labyrinthine intact), complete unilateral vestibular deafferentation (UVD) group, simultaneous complete bilateral vestibular deafferentation (BVD) group (n = 20 in each group). Subgroups (n = 10 in each subgroup) were set for static status or following angular acceleration stimulation in each group.

Objective: To evaluate the application of Ni-Ti shape memory alloy stent for treating tracheal stricture, including its indications and complications.

Methods: Forty-three patients clinical data were analyzed, among them, 15 suffered from tumor; 7 trauma; 4 granulation; 1 Wegener's granuloma, 2 rhinoscleroma, 1 without clear diagnosis; 7 were relapsing polychondritis; 1 were respiratory amyloidosis; 4 were tracheobronchial tuberculosis, 5 were tracheobronchomalacia. The stricture degree: Level I: 15 patients, Level II:24 patients, Level III:4 patients.

[Adjuvant treatment of anisodamine to acute serous otitis media].

Objective: To evaluate the adjuvant treatment of anisodamine to acute serous otitis media.

Method: Sixty-one acute otitis media patients were divided randomly into two groups. Group A with 30 patients were treated with 1% ephedrine nosedrop, antibiotic and antihistamine.

[Effect of nitric oxide in vestibular compensation].

Objective: To study the effect of nitric oxide (NO) in vestibular compensation after unilateral vestibular deafferentation.

Methods: Eighteen animals were divided into two groups, 6 of group a as control, 12 of group b received gentamicin intratympanic injection in the left ear. Half of the animals were killed respectively after 5 days and 10 days.
