Classification of non-allergic rhinitis based on inflammatory characteristics.

The study aims to investigate nasal and lower airway inflammation in patients with non-allergic rhinitis (NAR), and to discuss a method of NAR classification based on inflammatory characteristics and its clinical significance. A total of 117 NAR patients admitted to our hospital from June 2010 to June 2011 were enrolled in this study, 162 healthy participants were employed as healthy controls. Nasal and lower airway inflammation were evaluated using the skin prick test, nasal and pulmonary visual analogue scale scoring, cell blood count, nasal douche, induced sputum assay, nasal provocation test, and bronchial provocation test.

The normative value of inflammatory cells in the nasal perfusate of Chinese adults: a pilot study.

Objective: To establish stable, well-accepted nasal perfusion and a normative value of classifying cells in the nasal perfusate of Chinese adults.

Methods: A total of 500 healthy adults were divided into two groups of 250 people per group (group A, 16-30 years old and group B, 31-60 years old; male-to-female ratio, 1:1). All volunteers were non-smokers; they were irrigated with saline, and multiple inflammatory cells in the perfusate were analyzed.

[The study of methodology and reference values for cellularity of nasal lavage of normality].

Objective: To study the reference values for differential cell counts in nasal lavage of normality in Nanjing.

Method: The total and differential cell counts were examined in nasal lavage from samples of a total of 300 healthy non-smoking adult volunteers.

Result: Nasal lavage succeeded in 281 subjects, the achievement ratio was 93.
