ABSTRACT
Omalizumab,as a biological agent targeting IgE,is a recombinant humanized monoclonal antibody and the first targeted drug approved for treating moderate-to-severe bronchial asthma.By reviewing one case of aspirin-induced asthma complicated with nasosinusitis and otitis media,we discussed the value of omalizumab in the treatment of asthma and its complications,aiming to provide a reference for clinical practice.

Objective To explore the correlation between ostiomeatal complex(OMC)variation, nasal septum deviation and nasosinusitis with CT imaging.Methods The clinical and imaging data of 256 patients undergoing nasal and paranasal CT examination from June 1, 2015 to May 30, 2016 were retrospectively analyzed. Patients with paranasal sinus fractures, tumors and artifacts were not included in this study.Taking the image of standard coronal MPR built with thin axial sections at the level of middle of semilunar fissure as observing image,and the direction,location and extent of OMC variations were observed and recorded. The patients were divided into two groups according to the presence or absence of nasal septum deviation.OMC mutation,the incidence of unilateral mutation,incidence of paranasal sinusitis and the incidence of unilateral bilateral nasal sinusitis between the two groups was analyzed by χ2test with two independent samples. Then according to the presence or absence of OMC mutation, the patients were divided into two groups.The incidence of paranasal sinusitis and bilateral paranasal sinusitis were compared between the two groups. Results Two hundred and fifty six cases of CT imging of parannasal sinus were included in the study,96 cases were with nasal septum deviation, 160 were with non-deviation of nasal septum. The incidence rate of OMC variation between the two groups showed significant difference(χ2=38.40,P<0.05).The incidence rate of unilateral and bilateral OMC variation showed significant difference(χ2=13.70,P<0.05),among which 54 were unilateral variations,50(92.6%)variations were located at the same side of nasal deviation(side of the nasal cavity widened).The incidence rate of sinusitis between the two groups showed non-significant difference(χ2=0.50,P>0.05).The incidence rate between unilateral and bilateral nasosinusitis showed non-significant difference(χ2=2.25,P>0.05).Of the 256 cases,128 were with OMC variations,and 128 were with non-OMC variation.The incidence rate of nasosinusitis between the two groups showed non-significant difference(χ2=0.56,P>0.05). The incidence rate between unilateral and bilateral nasosinusitis showed non-significant difference(χ2=3.57,P>0.05). Conclusion Ipsilateral OMC variation occurred in nasal septum deviation might be a compensation to nasal cavity widening while not a obstructive factor in causing nasosinusitis.
ABSTRACT
Histone deacetylases (HDAC) are pivotal enzymes in many physiological processes widely expressed in almost all tissues including chromatin remodeling,regulation of protein transcription,cell cycle,aging,oxidative stress,inflammation and expression of immune genes.Recent studies indicated that the equilibrium state of histone acetylation and deacetylation is closely related to respiratory tract inflammation,and the unbalanced expression of HDAC could induce the expression of genes related to the inflammatory cytokines and oxidative stress.Now the structure and classification of HDAC and the updated results on HDAC in the inflammatory respiratory diseases are herewith reviewed in present paper.
ABSTRACT
Objective:This paper aims to demonstrate the maxillary mucosa restoration after operation to the nasal fungal sinusitis. Methods Observation by microscopic, transmission electron microscopic and scanning electron microscopic was done to the same parts in the maxillary mucosa 3-4 months before and after the endoscopic sinus surgery in the 24 cases of the nasal fungal sinusitis during 2003-2005. Result: Before the operation, all the cases demonstrated epithelia shedding, proliferation, squamous metaplasia, glandular and fibrous tissue proliferation and lymphocytes infiltration. The microtubule was abnormal and mitochondria diminished,3-4 months after operation, the cavity was clear and smooth and the epithelia complete. The cilia average increased and the cilia lined in the same direction. The structure of microtubules was clear. The mitochondria was elongated and dense. Conclusion: There was no significant difference in the damage on ultramicrostructure of the maxillary mucosa between the chronic nasal sinusitis and chronic nasal fungal sinusitis. It is crucial in the successful recovery that the operation gives a thorough clean to the fungal clot and sinus aeration, and that good cleaning and sinus aeration are maintained after the operation. The ultramicrostructure restoration and the function recovery of mucosa will be achieved after careful cleaning for 3-4 months after operation.
ABSTRACT
Objective Clinical studies of Chronic Nasosinusitis by endoscopic intranasal sinus surgery under head mirror.Methods 43 cases were operatived by endoscopic intranasal sinus surgery under head mirror.Results 29 cases were cured and 14 cases effectived, Efficiency 100.00%. 17 uncinate process residue, There were no severe complications.Conclusion Endoscopic intranasal sinus surgery under head mirror for chron icsinu sit is and nasal polyps can solveo stiom eatalcomplex anom alism more effectively and raise the cure rates of sinusitis (type Ⅰ、Ⅱ) than conventional technique in surgery.This choice will reduce the cost of the patients than Endoscopic sinus surgery, but must be provided with the knowledge in nasal and paranasal sinus, grapple the gist of endoscopic intranasal sinus, strict Surgical indication at the same time.
ABSTRACT
Objective To evaluate the outcomes of endoscopic sinus surgery (ESS) for children with chronic rhinosinusitis, who had no response to medication. Methods A total of 112 children (aged 12 to 17 years) with chronic rhinosinusitis caused by abnormal anatomy of the nose cavity were treated by ESS in our hospital. Septorhinoplasty was performed on the patients under an endoscope. Conchoplasty, adenoidectomy, or nasal polypectomy was performed simultaneously if necessary. Results The patients were followed up for 6-23 months (mean 13 months). The symptoms of rhinosinusitis disappeared in 110 patients (98.2%); whereas the other 2 patients showed no obvious improvement after the operation. Conclusions By using microinvasive ESS combined with conchoplasty, children with rhinosinusitis caused by abnormal anatomy that does not respond to medication could be cured.
