[Objective] To study the aeroallergens in the patients with allergic rhinitis in Guangzhou.[Methods] Using the German screen allergens quantitative detection system to determinate serum aeroallergen specific IgE and total IgE levels of 625 cases with allergic rhinitis diagnosed in The Third Hospital of SUN Yat-sen University.The samples were stratified on two age groups:the juvenile and the adult.Difference of serum aeroallergen specific IgE of the two groups was investigated.[Results]Aeroallergen specific IgE antibody in the serum of 625 patients with allergic rhinitis were positive.Total IgE in serum was positive in 413 cases,accounting for 66.1%.The positive rate of total IgE was less than that of aeroallergen specific IgE.The positive rate of aeroallergen specific IgE in order were mite mixture (84.32%),cockroach (19.04%),cypress (15.20%),cat-dog epithelia (13.12%),tree mixture (7.20%),ragweed (5.12%),humulus lupulus (1.76%),mugwort (1.76%),mould mixture (1.44%).In the two groups,the positive rate of aeroallergen specific IgE in order were similar.There were significantly higher sensitivity and positive rate of mite mixture in the juvenile group than the adult group (P ＜ 0.01).[Conclusion] The most important aeroallergens are mite mixture,cockroach,cypress,cat-dog epithelia,which could be referenced as Guangzhou patients .The juvenile is more sensitive to mite than the adult.

ABSTRACT]OBJECTIVETo study the compliance to sublingual immunotherapy(SLIT) in patients with allergic rhinitis(AR) in Guangzhou city.METHODSFrom January 2014 to May 2014, 202 patients with AR received SLIT were followed up by telephone. According to age, the patients were divided into group A(age<14 years) and group B(age≥14 years). The compliance to SLIT was analyzed and the reasons of poor compliance were investigated.RESULTSAmong 202 patients, only 93 cases(46.04%) were successfully followed up by telephone, 109 cases(53.96%) were lost to visit. Among the 93 cases of successful follow-up, the good compliance rate was 29.03%(n=27), the poor compliance rate was 70.97%(n=66). compliance to SLIT was not affected by age and gender(P>0.05). Main reasons for poor compliance included poor efficacy (48.48%), insufficient education about SLIT (16.67%), inconvenience (15.15%), and adverse reactions(10.61%).CONCLUSION In Guangzhou city, lost follow-up rate in AR patients receiving SLIT is high. Compliance to SLIT is relatively low and improvements shall be made.

Objective:To evaluate the correlation between the polysomnographic findings and the degree of obstruction caused by adenoid and tonsillar hypertrophy in children with clinical history of apnea. Method: Retrospectively studied the children who were diagnozed clinically of, obstructive sleep apnea hypopnea syndrome(OSAHS) and underwented polysomnograph and endoscopy. Patients were divided nto OSAHS and non-OSAHS group according to polysomnographic findings. Result: Ninty-four children were involved in the study population, and 63 children of them were male. The mean age of the children at the time of inclusion in the study was 6.7 years. 36 children(38.3%) diagnosed OSAHS clinically had normal polysomnographic findings. No differences were found between children with PSG-documented OSAHS and others. Tonsillar and/or adenoid hypertrophy were not correlated to more severe apnea among enrolled children. Conclusion-There was no significant correlation between polysomnographic and clinical findings in children with OSAHS.

Objective To investigate the expression of MUC5AC in human sinus mucosa and compare the expression of MUC5AC mRNAs in normal and chronic sinus mucosa. Methods Thirty two chronic ethmoid sinusitis mucosa samples and 7 normal ethmoid sinus mucosa samples were used. The protein expression of MUC5AC was examined by using immunohistochemical method. RNAs were extracted from sinus mucosa, and fluorescent quantitative nested RT-PCR was performed for MUC5AC. Results The mean gray scale of MUC5AC protein expression was 159. 72 ± 14. 14 in chronic ethmoid sinusitis mucosa and 115.80 ±31.58 in normal ethmoid sinus mucosa. There was significantly different between two groups (t =3.57, P ＜0.01). The levels of MUC5AC mRNAs in chronic rhinosinusitis [(35.80 ± 19. 74) × 105copies/μg] were higher than those in normal sinus mucosa [(4. 66 ± 2. 47) × 105 copies/μg] . M UC5 AC mRN A expression had significant difference between chronic ethmoid sinusitis mucosa and normal sinus mucosa(t =4. 12, P ＜0.01). Conlusion This result suggested that up-regulation of MUCSAC in chronic rhinosinusitis might play an important role in the pathogenesis of sinus hyperesecretion in chronic rhinosinusitis.

OBJECTIVE To obtain and compare the clinical characteristics in patients with allergic rhinitis(AR) and nonallergic rhinitis(NAR) and investigate the trends in the proportion of AR and NAR in recent 10 years in Guangzhou. METHODS 5486 patients with nasal hyper-reactivity symptoms were divided into the AR group and NAR group. Clinical data including gender, age distribution and seasonality were analyzed. RESULTS The trends in the proportion of AR and NAR during the past decade did not change significantly. Male made up the majority of AR patients and NAR patients and AR patients were significantly younger than NAR patients. Male AR patients were significantly younger than females, while there were no significant difference in the age distribution among the male NAR patients and female ones. As the age increasing, the proportion of AR and NAR patients in overall study population present opposite tendency. The main onset season in AR was summer and in NAR was winter in Guangzhou city. CONCLUSION There were significant differences between AR and NAR in age, gender and seasonality. However, the trends in the proportion of AR and NAR in recent 10 years did not change significantly in Guangzhou.

OBJECTIVE To drew the map of distribution of concealed sites in epistaxis and optimize the mode of diagnosis and treatment. METHODS We have searched 117 references on intractable/refractory/latent epistaxis treated under nasal endoscopy in the last decade, including 11 708 cases with epistaxis. There were total 11 860 cases in this study plus 152 cases in our hospital. We summed up the experiences of the optimized treatment mode performed on concealed epistaxis, which was searching the accurate bleeding areas by nasal endoscopy and performing minimally invasive radiofrequency treatment without nasal packing. RESULTS We had found that the offending arteries about epistaxis are mainly sphenopalatine artery and anterior or posterior ethmoid artery. The frequency of bleeding areas came as follows: the vault of inferior nasal meatus in 3783 cases(31.90%), the olfactory sulcus of middle turbinate in 3522 cases(29.70%), the posterior regions of middle meatus in 1349 cases(11.37%), the regions of deviation of nasal septum in 1065 cases(8.98%), the foremost regions of nasal cavity in 738 cases(6.22%), and the others or uncertain in 1403 cases(11.83%). Finally, we drew a concise map of distribution about epistaxis on the basis of the concealed bleeding areas and offending vessels. 151 of 152 patients(99.34%) could find out the bleeding sites accurately and stop the bleeding through minimally invasive radiofrequency ablation. CONCLUSION We drew a map of distribution about epistaxis in concealed areas so that it is convenient for us to seek out the bleeding sites. Rational use of nasal endoscopy to explore the sites of intractable epistaxis and minimally invasive radiofrequency are optimized mode of treatment.

Objective]In order to study the impact of adenoid hypertrophy(AH)with allergic rhinitis(AR)in the otitis media with effusion(OME)in children,as well as to discuss the risk factors on the inducement of OME in patients with AH.[Methods]The clinical materials were collected and analyzed from 205 children with AH who admitted for surgical treatment between 2013 and 2015, including medical history and signs,acoustic immittance measurement,allergy screen as well as blood routine,and to evaluate the situation of OME and AR in patients with AH. All the data were analyzed by SPSS 20.0.[Results]Among the 205 AH children,66 cases(32.20%)were accompanying with OME. The AH patients aged 3-5 years had the highest incidence of OME,which decreased with age(P=0.018). It is significant on the prevalence of the OME in patients with AH between the two groups with and without AR (P = 0.010). In the logistic model investigating the risk factors of inducing OME among patients with AH,the third-degree AH, Type-three and the accompanying with AR were significant. The third-degree and third-type AH children were 2.729 and 6.390-folds higher than others respectively (P = 0.047,P = 0.001). The incidence of OME appeared to be 1.212-folds higher among patients with AR(P = 0.010).[Conclusion]Mechanical obstruction and AR played a superimposed role in the inducement of OME among patients with AH,which was effected by multiple factors. We should pay attention to the“lateral respiratory”allergic diseases on eustachian tube and middle ear.

OBJECTIVE To detect the expression of the Glucocorticoid receptor-?(GR-?)mRNA in nasal polyp and normal nasal mucosa and investigate the route of nasal drug administration in patients of nasal polyp. METHODS The expression of GR-?mRNA in 101 samples of nasal polyps and 31samples of normal nasal mucosa was examined by using Fluorescent quantitative PCR .RESULTS The level of GR-?mRNA in normal nasal mucosa(135.4? 5.25)?104 copy /?g were significantly higher than that in nasal polyps(23.5?12.1)?104 copy/?g . CONCLUSION Because of the low expression of GR-?mRNA in nasal polyps,the route of nasal drug administration in patients with nasal polyps may be in the part of normal mucosa,not in the mucosa of nasal polyps of the nasal cavity.

OBJECTIVE: To determine the ideal treatment for the pediatric patients with chronic rhinosinusitis. METHOD: Eighty-eight patients (aged 5-14 years) were divided into group A, B, C. In group A, 30 cases (60 sides) who had chronic rhinosinusitis without nasal polyps were treated systemically with medicine. In group B, 31 cases (62 sides) were chronic rhinosinusitis without nasal polyps and accompanied by adenoid vegetation and/or chronic tonsillitis,and were systemically treated with a combined therapy of medicine and adenoidectomy and/or tonsillectomy. In group C, 27 cases (54 sides) were chronic rhinosinusitis with nasal polyps,and were treated systemically with medicine and endoscopic sinus surgery. RESULT: All patients were followed up for 12-18 months, with an average of 16 months. In group A, 48 sides were cured, 8 sides improved and 4 sides showed no effect. In group B, 46 sides were cured, 10 sides improved and 6 sides showed no effect. In group C, 40 sides were cured, 8 sides improved and 6 sides showed no effect. There were no significant differences in the efficacy among the three groups (P > 0.05). CONCLUSION Systemic medical treatment should be the first choice for chronic rhinosinusitis in children. Children with adenoid vegetation and/or chronic tonsillitis are basically treated with systemic medicine combined with adenoidectomy and/or tonsillectomy. Administration of medicine before and after the endoscopic surgery is more efficient for chronic rhinosinusitis with nasal polyps in children.
