ABSTRACT
OBJECTIVE To investigate the relationship between the distribution of eosinophils(Eos) of nasal secretion and serum specific IgE(sIgE) titer in patients with allergic rhinitis, and to evaluate the diagnostic value of Eos in nasal secretion for allergic rhinitis. METHODS A total of 60 allergic rhinitis patients from Department of Otolaryngology, Beijing Shunyi Hospital of Traditional Chinese Medicine during Jan.2016 to June 2017 were selected as treatment group, and another 60 cases of non-allergic rhinitis and 30 normal persons in the corresponding time period were chosen as control group. Eos in nasal secretions and serum sIgE were measured in all the subjects and the relationship between Eos distribution and serum sIgE level was analyzed. RESULTS The Eos distribution and serum level of sIgE was consistent(κ=0.264, P=0.000) and statistical significance was found. The area of ROC of the Eos in nasal secretion was 0.881, the standard deviation was 0.025 and 95％ confidence interval was 0.841 to 0.924. The Udden index of ROC reached the maximum when the Eos in nasal secretion smear was graded as level 3, the sensitivity was 88.5％ and specificity was 99.4％. CONCLUSION Eos cytological examination of nasal secretions has some auxiliary value in the diagnosis of allergic rhinitis. It is a cheap, simple and rapid method, which can be used as an effective reference index for diagnosing allergic rhinitis in primary hospital.
ABSTRACT
OBJECTIVE:To investigate the bacteriological characteristics of nasal secretions of chronic rhinosinusitis(CRS)in our hospital,and conduct drug sensitivity test in order to provide theoretic reference for clinical treatment. METHODS:87 CRS patients underwent nasal endoscopic surgery were selected and the nasal secretions of patients were taken for bacterial culture. Automatic microbial analyzer was used to identify the bacteriological characteristics,and disk diffusion test was adopted for drug sensitivity test. RESULTS:Of 87 patients,bacterial strains were detected from 77 cases of nasal secretions,with positive rate of 88.5%. 112 strains were detected,including 81 strains of aerobic bacterium and 31 strains of anaerobic bacterium,and the most common bacterium were Staphylococcus aureus (20.54%). Antibiotics with the highest sensitivity was moxifloxacin (89.29%), followed by ciprofloxacin(87.50%),vancomycin(87.50%). CONCLUSIONS:The bacterial in nasal secretions of CRS patients has high positive detection rate and mainly are aerobic bacterium. Antibiotics should be used rationally according to the results of drug sensitivity test.
ABSTRACT
Objective To discuss the expression and significance of eotaxin in the nasal secretions of the patients with nasal pol-yps .Methods The nasal secretion samples were collected from 40 patients including 15 cases of nasal polyps ,15 cases of chronic si-nusitis and 10 cases of nasal septum deviation .The enzyme-linked immunosorbent assay(ELISA) was adopted to detect the concen-tration of eotaxin .Results The average concentration of eotaxin was (468 .82 ± 440 .64)pg/mL in nasal polyps ,(443 .85 ± 334 .68) pg/mL in chronic sinusitis and (149 .23 ± 49 .01)pg/mL in nasal septum deviation .The eotaxin concentrations in the nasal polyps group and the chronic sinusitis group were higher than those in the nasal septum deviation group ,the difference was statistically significant(P<0 .05) .Conclusion The eotaxin concentration in the nasal secretions of the patients with nasal polyps is significantly increaseed ,which might be concluded that eotaxin may play an important role in the occurrence and development process of nasal polyps .
