RESUMEN

Objective To explore the regulatory effect of miRNA on B-cell activating factor (BAFF) in chronic eosinophilic rhinosinusitis with nasal polyp (Eso CRSwNP).Methods Ten nasal mucosal samples were collected from Eso CRSwNP patients who were admitted and treated in our hospital between January 2012 and February 2013.Normal nasal mucosal tissues (n =10) served as control.The miRNA-targeting BAFF was predicted by bioinformatics tools.Immunohistochemistry and real time polymerase chain reaction (RT-PCR) were used to assess the protein expression of BAFF and the predicted miR-NA.The correlation between the predicted miRNA and BAFF was analyzed.Results Down-regulated expression of let-a was confirmed in Eos CRSwNP,while the BAFF protein expression was increased.Let-a was positively correlated with BAFF in nasal epithelia.Conclusions Let-a might contribute to mucosal eosinophilia in eosinophilic CRSwNP via targeting BAFF.

RESUMEN

Objective:To detect the expression of oncogene c-myc and explore its role on human aryngeal cancer.Method:The mRNA and of oncogene c-myc levels were detected in human laryngeal cancer tissues and iaryngeal normal tissues by the means of real-time PCR and immunohistochemistry,respectively.Result:Compared with normal laryngeal tissues,the mRNA and protein levels of oncogene c-myc were both upregulated in laryngeal cancer tissues of all differentiation degree(P<0.05).Moreover,the level of e-myc was inverse correlated with the differentiation degree in human laryngeal cancer tissues.Conclusion:The oncogene c-myc is overexpressed in human laryngeal cancer tissues,and c-myc may play an important role in carcinogenesis and progression of human laryngeal cancer tissues.It may provide a new target for gene therapy of human laryngeal cancer.

RESUMEN

OBJECTIVE@#To report 13 cases of ethmoid osteoma removed through an endoscopic approach and discuss the operative technique and clinical value.@*METHOD@#Thirteen cases with ethmoid osteoma were retrospectively reviewed in the study. All procedures were performed with CT image guidance-according to the site of attachment. The anterior ethmoid cell was resected, and the whitish osteoma found. A double blunt elevator was used to separate the osteoma from ethmoid cell, and to push the osteoma medially toward the nasal septum, and (or) inferiorly toward the middle meatus. This method was performed in 7 patients (8 sides), whose CT scan showed the osteoma bases were not attached to lamina papyracea, and (or) anterior skull base. The others were drilled out with a intranasal powered drill for its attached to lamina papyracea in 4 patients and to anterior skull base in 2 patients.@*RESULT@#Thirteen cases of ethmoid osteoma were removed completely through an endoscopic approach and there were no intraorbital or intracranial complication. Endoscopy showed normal epithelization at around 6 to 8 weeks after surgery.@*CONCLUSION@#Preoperative CT scans, including coronal and axial images, is very helpful to determine the sites of the osteoma attachment and plan the operation. Endoscopic removal of ethmoid osteoma is not only an ideal, less invasive surgical approach, but also no cosmetic alteration.

RESUMEN

OBJECTIVE@#To study the effects of dexamethasone and histamine on the expression of MUC5AC mRNA and protein in human nasal polyps.@*METHOD@#All samples were randomly divided into control group, histamine stimulating group and dexamethasone group. The expression of MUC5AC mRNA and MUC5AC protein in nasal polyps were respectively detected by the methods of reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical assay.@*RESULT@#The expression of MUC5AC mRNA (0.6389 +/- 0.0526) and protein (0.1934 +/- 0.0137) in histamine stimulating group were significantly higher than those of control group (0.3495 +/- 0.0357 and 0.1172 +/- 0.0173, respectively) and reduced (0.4988 +/- 0.0603 and 0.1444 +/- 0.0075, respectively) after treatment with dexamethasone.@*CONCLUSION@#Histamine upregulates MUC5AC mRNA and protein expression. Dexamethasone downregulates MUC5AC mRNA and protein expression, which may be one of the mechanisms of downregulating mucus overproduction by dexamethasone in nasal polyps.

RESUMEN

OBJECTIVE@#Whether inhalation of pulmicort into the sinus of chronic rhinosinusitis patients could improve reepithelization after endoscopic sinus surgery was assessed.@*METHOD@#Prospective study 60 patients with chronic rhinosinusitis after endoscopic sinus surgery were divided into 2 groups randomized, the one was treatment group, and the other was control group. The patients in treatment group received inhalation of pulmicort 2 ml plus 0.5% Aeuromycin solution 10 ml by oxygen driving force, once a day, persisting for 3 weeks. The patients in control group received Rhinocort. Besides the different therapies above mentioned above therapy was different, two groups received the same conventional route therapy. To observe the time of reepithelization under nasal endoscope, was observed, respectively.@*RESULT@#The average time of reepithelization in treatment group was (5.3333 +/- 0.9942) weeks. The other group was (6.6667 +/- 1.3476) weeks, the statistical difference between the two groups was very significant.@*CONCLUSION@#Inhalation of pulmicort into the sinus can promote reepithelization and shorten the time of treatment.

RESUMEN

OBJECTIVE@#To evaluate the method of the perioperative blood glucose control in chronic rhinosinusitis coexisting diabetes.@*METHOD@#Twenty-two cases of chronic rhinosinusitis coexisting diabetes were investigated retrospectively, including one case of type 1 diabetes and 21 cases of type 2 diabetes. The study cohort was divided into two groups, the one was complication group and the other was non-complication group. The patients in complication group were injected insulin to control blood glucose level, and the patients in non-complication group were prescribed oral medicine.@*RESULT@#Blood glucose levels below 9.0 mmol/L in complication group and below 7.0 mmol/L in non-complication group were both the surgical indication for the patients in this research cohort. Twenty-one cases were completely recovered and one case made progress significantly.@*CONCLUSION@#The detection of blood and urine glucose levels must be the routine item before the nasal endoscopic surgery. To control blood glucose levels in type 2 diabetes with non-complication, oral medicine is the first choice, in type 1 diabetes and type 2 diabetes with complication, insulin should be first considered.
