Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2009;(20):923-925,929. doi:10.3969/j.issn.1001-1781.2009.20.004

Objective:To detect the mucin gene (MUC2,MUC5AC,MUC5B,MUC18 and MUC19)expression in the nasal polyps, allergic rhinitis (AR)and the normal nasal mucosa in human. To investigate the role and clinical significance of mucin gene in the pathogenesis of nasal polyps and AR patients .Method:We obtained samples from 35 cases of nasal polyps,18 cases of AR inferior turbinate and 18 cases of simple nasal septum deviation inferior turbinate. Specimens were analyzed with RT-PCR and Real-time FQ-RT-PCR.Result:The results of RT-PCR and FQ-RT-PCR showed that the expression of MUC5AC,MUC5B in nasal polyps and AR patients was significantly higher than that in normal mucosa(P<0.05). The expression of MUC5AC,MUC5B in nasal polyps was not significantly different from that in AR patients(P>0.05). The expression of MUC2, MUC18 in nasal polyps and AR was not significantly different from that in normal mucosa(P>0.05). And the results of RT-PCR for MUC19 expression in AR was higher than that in nasal polyps group and normal group(P<0.05 or P<0.01).Conclusion:MUC5AC and MUC5B are highly expressed in epithelium of human nasal polyps and AR, and they take part in mucus over-secretion in nasal polyps and AR.The expression of MUC19 in AR was higher than that in nasal polyps group and normal group. It indicates that the secretion of MUC19 in allergic rhinitis was on high level. There was no difference of the expression of MUC2 and MUC18 in nasal polyps group, AR group and in normal group.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2009;(23):1069-1070,1073. doi:10.3969/j.issn.1001-1781.2009.23.005

Objective:This article was a retrospective analysis on the preoperative CT scan of fungal sinusitis patients.The non-distinctive clinic feature was suggested to improve the accuracy of preoperative diagnosis.Method:A retrospective analysis was made for 176 patients with fungal sinusitis,which were confirmed by postoperative pathologic disanosis from January 2000 to January 2008.Every patient was performed both CT examination and nasalendoscopy preoperatively. All patients underwent endoscopic sinus surgery and the lesions in sinus were cleared and confirmed fungal infection by pathology.Thirty-five cases fungal infection located in sphenoid sinus,84 cases in maxillary sinus,49 cases in both maxillary and ethmoid sinus,3 cases in all sinus,5 cases in both ethmoid and sphenoid sinus.There were 179 sinuses in 176 patients were infected. Result:This group totally had 175 cases(179 sides). One hundred and seventy-three cases had unibilateral lesion,3 cases had bilateral lesion. The CT scan showed non-distinctive features including unifom dense,uneven dense in the sinus and bone resorption of the inner side bone wall. Five cases in sphenoid sinus lesion were found calcification in CT scan but 8 cases didn't show such features.Among these cases. 5 cases showed uniforra.dense and 3 cases showed uneven dense. In 84 cases maxillary sinus lesion,there were 12 cases without distinctive change,among these cases,8 cases showed uniform derise,4 cases showed uneven dense and 5 cases had boRe resorption. In 49 cases both ethmoid and maxillary sinus lesion,13 cases didn't show distinctive change,among these cases,9 cases showed uniform dense,4 cases showed uneven dense and 6 cases had bone resorption. Five cases had calcification in the both sphenoid and ethmoid sinus. Totally 81.56% of these patients had calcification feature in the CT scan.Conclusion:The calcification in the lesion of sinus is usually featured as characteristic manifestation of fungal sinusitis. But in clinic,the calcification does not exit in some patient's CT scan. When being absent of the featured sign in CT scan,the fungal sinusitis have to be diagnozed by other detecting means,even postoperative pathology.

Objective:To study the expression of MMP-9 and eosinophils in nasal polyps and its influence on the prognosis. Method:Study the expression of MMP-9 and EOS on the tissue of nasal polyps of patients who were cured or recurrent and normal nasal mucosa(NM) by immunohistochemisty and HE staining. Result:In the patients of recurrent group (Group B) , the expression of MMP-9 was much stronger than that of good prognosis group (Group A) and NM. The MMP-9 was stronger in the eosinophil nasal polyps than that of non-eosinophil groups. The percentage of EOS in Group A was 16.67% , while 62.50% in the Group B. Conclusion:The stronger expres-sion of MMP-9 on Group B and eosinophil group indicated that MMP-9 might affect the prognosis of nasal polyps through inducing the number of EOS in the mucosa. MMP-9 may be one of the risk factors for the relapse of nasal polyps.

Objective:To analyze the result of smooth pursuit test(SPT) in unilateral vestibular peripheral vertigo and investigate its influencing factors.Method:Smooth pursuit test (SPT) and spontaneous nystagmus (SN)were examined in one hundred and eighty-five patients with unilateral peripheral vertigo(case group) and 51 normal persons(control group) by Video-Nystagmography (Synapsys, France), and the gain of SPT and SN were selected as the observation parameters in order to analyze the waveform and gain of SPT and the relativity between SN and the gain of SPT.Result:Of the 185 patients, 105(56.8%),72(38.9%) and 8(4.3%) cases producedⅠ,Ⅱ and Ⅲ waveforms respectively. Of these patients, 58(31.4%) demonstrated SN and none had Ⅳ waveform. While of 51 normal persons, 38(74.5%), 13(25.5%) persons producedⅠand Ⅱwaveforms repectively and there were no Ⅲ, Ⅳ waveforms or SN. There was statistical significance between the stong and weak gain of SPT in these two groups. Weak gain was significantly different between two groups. The stong and weak gain of SPT in case group were 0.86±0.06,0.80±0.06; 0.78±0.09, 0.65±0.1; 0.68±0.13, 0.45±0.12. The relativity between SN and the gain of SPT was positive when they had same direction(r_s=-0.63,P＜0.05)and negative when opposite (r_s=0.34,P＜0.05).Conclusion:Ⅰ,Ⅱ,Ⅲ three waveforms of SPT could appear in unilateral vestibular peripheral vertigo and the corresponding gains are gradually decreasing.SN is the influencing factor of SPT.

Fang ZHANG ; Xuejun JIANG

Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2010;(1):21-24. doi:10.3969/j.issn.1001-1781.2010.01.007

Objective:To observe the anatomic characteristics of supratubal recess and the morphological change of it in the sick ear. To investigate the relation between the morphological changes of supratubal recess and otitis media.Method:Using high resolution CT to observe and measure the supratubal recess of the normal ears and the ailing ones.Result:For the normal adults, the anteroposterior diameter of the supratubal recess is(3.83±1.28)mm,the vertical diameter(3.67±1.14)mm,the height(3.76±0.36)mm;and the length of the cog is(2.84±0.38)mm.The size of the supratubal recess showed no significant difference between left and right(P＞0.05).There was no relationship between the size of the supratubal recess and pneumatization of mastoid cells (P＞0.05).There was significant differences in size of the supratubal recess between normal ears and the ears with cholesteatoma(P＜0.05),but there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells(P＞0.05)in the ears with cholesteatoma.There was no significant differences in size of the supratubal recess between normal ears and the ears with chronic otitis media(P＞0.05).In the ears with cholesteatoma,40% had osseous destruction in supratubal recess.Conclusion:For the normal adults, the size of the supratubal recess showed no significant difference between left and right, and there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells. Anterior tympanic isthmus , posterior tympanic isthmus and supratubal recess which is the supplement of the formers constitute the air way between attic and mesotympanum. The supratubal recess of the cholesteatoma is smaller than the normal, when the eustachian tube dysfunction occurs, the air way in the middle ear would herein be affected, and cholesteatoma forms eventually. There was no significant differences in size of the supratubal recess between normal ears and ears with chronic oti-tis media, as in the clinic.The effect of the supratubal recess should be taken into account when we consider the pathogeny and treatment of the middle ear cholesteatoma.
