[Show abstract][Hide abstract] ABSTRACT: A conchal non-pneumatized sphenoid sinus was previously considered to be a contraindication to the endoscopic transsphenoidal route to the sella due to its small sellar floor and poor anatomical landmarks, such as the optic nerve canal, opticocarotid recess and internal carotid arteries canal. The present study aimed to investigate the methodology and characteristics of the endoscopic transsphenoidal resection of sellar tumors with a conchal sphenoid sinus. Two patients with sellar tumor patients and non-pneumatized sphenoid sinuses received endoscopic transsphenoidal surgery. The two conchal sphenoid sinuses were accessed safely, total resection was achieved and no serious complications occurred. Therefore, the presence of a conchal non-pneumatized sphenoid is not an absolute contraindication for employing the endoscopic transsphenoidal route in the resection of sellar tumors; a positive outcome may be achieved, in particular when the surgery is performed by an experienced otolaryngologist.
[Show abstract][Hide abstract] ABSTRACT: Objective:
To analyze the risk factors for allergic rhinitis and provide the scientific basis for disease control and intervention through investigation of the elementary and middle school students with allergic rhinitis in Changsha.
From January to April 2012, we randomly enrolled the elementary and middle school students aged at 10-17 years old in Changsha. We explored the risk factors for allergic rhinitis by using stratified and cluster sampling survey, questionnaire investigation, physical examination, skin pricking needling experiment and statistical analysis.
A total of 814 students were investigated in cluster sampling survey. The result of the incidence of allergic individual was 26.3% and the prevalence of allergic rhinitis was 17.2%. Analysis of Visual Analog Scale Questionnaire (VAS) showed that allergic rhinitis exerted significant effect on student's character, memory, sleep quality, etc.
The prevalence of allergic rhinitis in the elementary and middle school students aged in Changsha is 17%-20%. The incidence and development is related to environment, genetic and living habits, which affects people's character, memory and sleep quality significantly.

[Show abstract][Hide abstract] ABSTRACT: To modify the endoscopic frontal sinus surgery and improve the therapeutic effect of recurrent chronic frontal sinusitis (RCFS). Eighty-five patients with RCFS were divided into two groups. Endoscopic frontal sinus surgery through an approach of Frontomaxillary Process-Agger Nasi, a modified Draf IIb procedure, was carried out in 51 patients (Group A), and conservative medication was applied in 34 patients as control (Group B). The therapeutic effect was prospectively evaluated with statistically validated measures of sinusitis-specific quality of life, sino-nasal outcome test-20 questionnaire (SNOT-20). Compared with pre-treatment, the average total score of SNOT-20 in RCFS patients was significantly decreased at the time of 6, 12 months after modified endoscopic frontal sinus surgery and medical treatments (p < 0.05). However, the total score of SNOT20 was significantly lower in group A than group B at the same period of the follow-up after treatments (p < 0.05). The overall efficacy evaluated by patients’ self showed that the rate of “much improved” and “improved” was respectively 68.6 and 17.6 % in group A, and significantly better than group B (p < 0.001). Furthermore, the frontal sinus patency rate in group A was 85 %, and significantly higher than group B (p < 0.001). Endoscopic frontal sinus surgery through an approach of Frontomaxillary Process-Agger Nasi, a modified Draf IIb procedure, is an effective procedure to treat the RCFS.

[Show abstract][Hide abstract] ABSTRACT: Anticholinergic drugs or vidian neurectomy can alleviate the symptoms of allergic rhinitis.
To show that inhibition of the cholinergic nerve influences the balance of T-helper type 1 and 2 cells in allergic rhinitis mice.
Twenty-four mice were randomly allocated to 1 of 4 groups: control, model, model with ipratropium bromide treatment, and model with 6-hydroxydopamine treatment. Allergic model-treated mice were sensitized with ovalbumin. Evaluation of allergic symptoms was recorded according to a symptom score. Ovalbumin serum IgE was measured by enzyme-linked immunosorbent assay. Expression of interleukin-4, interferon-γ, forkhead box P3, substance P, and vasoactive intestinal peptides was detected by immunohistochemistry and imaging analysis.
Symptoms in allergic mice were significantly alleviated by ipratropium bromide. Ovalbumin serum IgE and eosinophils of nasal mucosa were significantly decreased. Interleukin-4 expression level was significantly higher in the allergic model group than in the control group and significantly decreased by ipratropium bromide (P < .05). In contrast, the expression of forkhead box P3 was lower in the allergic model group than in the control group and increased with treatment by ipratropium bromide (P < .05). Conversely, interferon-γ expression was not changed by anticholinergic treatment in the nasal mucosa of allergic mice. Expression of substance P and vasoactive intestinal peptide was significantly increased in allergic mice and decreased by ipratropium bromide. Sympathetic denervation did not change the expression of interleukin-4, interferon-γ, forkhead box P3, substance P, and vasoactive intestinal peptide.
inhibition of the cholinergic nerve not only alleviated symptoms of allergic rhinitis by inhibiting the impulse of the parasympathetic nerve but also modulated the T-helper type 2-predominant immune reaction, expression of neuropeptides, and related inflammation factors.

[Show abstract][Hide abstract] ABSTRACT: To explore the therapeutic effects of endoscopic sinus surgery on symptoms and quality of life of patients with chronic rhino-sinusitis (CRS).
A survey of symptoms and quality of life was conducted using Sino-nasal Outcome Test-20 (SNOT-20) questionnaire with 76 patients before and after endoscopic sinus surgery. The overall effect of endoscopic sinus surgery on CRS was subjectively self-evaluated by patient.
After 6 months following-up, the total SNOT-20 score of patients was significantly decreased from the baseline (P<0.001). The most important 5-items were found to be "thick nasal discharge", "need to blow nose", "dizziness", "frontal pain", and "lack of a good sleep". Other items, related to sleep and emotion, were also significantly improved: the proportion of responses of "much improved", "improved" and "no-improved" were 56.3%, 33.3%, 10.4%, respectively.
Endoscopic sinus surgery demonstrated positive effects on symptoms and quality of life of CRS patients.

[Show abstract][Hide abstract] ABSTRACT: To investigate aeroallergen spectrum and allergy positive rates of patients with child allergic rhinitis and analyze its related factors.
Skin prick test was carried out in 562 cases with child allergic rhinitis using 13 inhaled allergens, and detailed history was collected in all cases.
Four hundred and fifty-seven (81.3%) of 562 cases showed positive reaction to at least one allergen out of 13 allergens. The most common allergens found in patients was Dermatophagoides farinae and Dermatophagoides pteronyssinus, and positive reaction was 93.1% in child allergic rhinitis, followed by tropical mite, Periplaneta americana, Blattella germanica and dog hair. The pollen allergen, most common in American and European, was pretty rare in this study. The prevalence of child allergic rhinitis was significantly higher in urban than in rural (P<0.01). There was no adverse effect appeared in children with allergic rhinitis underwent skin prick test.
The major allergen of allergic rhinitis is mite for child allergic rhinitis, and relates to housing enviroment. Most of patients with child allergic rhinitis can be treated by the mite specific immunotherapy. The skin prick test is a safe technique for diagnosis of children with allergic rhinitis.
