RESUMO
Objective: To summarize the preliminary experience in the treatment of esthesioneuroblastoma (ENB) and to explore the effect of age, chemotherapy, modified Kadish stage and pathological grade on the prognosis of ENB. Methods: The clinical data of 87 ENB patients from the First Affiliated Hospital of Sun Yat-sen University and Sun Yat-sen University Cancer Center between June 2002 and November 2017 were retrospectively analyzed. The modified Kadish stage was used to evaluate the extent of the lesions, and the Hyams grading system was used for pathological grading. The patients were followed up regularly to evaluate the recurrence and metastasis of the tumor. Cox proportional hazard model was used for univariate and multivariate analyses. Prognostic factors with P<0.05 in univariate analysis were included in multivariate analysis. After controlling the confounding factors, the model coefficients were used to calculate the hazard ratio (HR) and 95% confidence interval (CI). Results: The median follow-up time of ENB patients was 29 months, and the 5-year overall survival rate was 39.3%. In univariate analysis, age, chemotherapy, modified Kadish stage and pathology grade were independent predictors of overall survival, while gender, radiotherapy and surgery were not prognostic factors. Multivariate analysis showed that modified Kadish stage and pathology grade were independent predictors of overall survival rate after excluding confounding factors. Conclusions: Age, chemotherapy, modified Kadish stage and pathological grade are taking important role in the overall survival rate of patients with ENB. Modified Kadish stage and pathological grade are independent predictors of overall survival rate.

<p><b>OBJECTIVE</b>To explore the cause, urgent management, further treatment, outcome and prevention of internal carotid artery (ICA) injury during transnasal endoscopic surgery.</p><p><b>METHODS</b>Five ICA injury happened during transnasal endoscopic surgery of sphenoidal sinus and (or) sellar region, involving 1 case of traumatic optic neuropathy, 1 case of sphenoidal cyst, 1 case of fungal sphenoid sinusitis, 1 case of sellar adenoid cystic carcinoma and 1 case of pituitary tumor. These five cases were from three different hospitals in 1990 - 2009, and the clinical data were collected and retrospectively reviewed.</p><p><b>RESULTS</b>Injury of ICA was related with improper anatomic localization and operative procedures. The locations of injury were in cavernous segment in 3 cases, lacerum segment in 1 case, and clinic segment in 1 case, respectively. The types of injury included 3 cases of bleeding of laceration, 1 case of carotid cavernous fistula and 1 case of pseudoaneurysm. Salvage sphenoid sinus packing with vaseline strip and subsequent intravascular stent graft implantation (2 cases) and endovascular embolization (2 cases) effectively controlled bleeding. Four cases were successfully treated without craniocerebral or ocular complications, only 1 case died of massive blood loss. Among 4 survival cases, 1 patient abandoned further therapy, the other 3 patients were cured of primary disease by reoperation or subsequent treatment.</p><p><b>CONCLUSION</b>Preoperatively, reading carefully the imaging data, intraoperatively, identifying anatomical positions accurately, performing proper operation, and stopping bleeding decidedly, postoperatively, seeking interdisciplinary cooperation to repair vascular damages, all these procedures can effectively reduce the surgical risk of ICA injury.</p>

<p><b>OBJECTIVES</b>To explore the time regularity of nasal mucous transitional course of different sinuses after functional endoscopic sinus surgery.</p><p><b>METHODS</b>Seventy-seven chronic rhinosinusitis patients following functional endoscopic sinus surgery were prospectively collected. The endoscopic appearances of different sinuses were respectively evaluated with Lund-Kennedy scoring system in 2 weeks, 1, 2, 3, 6, 9 months, and 12 months postoperatively. Then the endoscopic scores and epithelization proportions of different sinuses in different stages were analyzed and compared.</p><p><b>RESULTS</b>Of 77 patients, 154 maxillary sinuses, 154 ethmoidal sinuses, 138 frontal sinuses, and 129 sphenoidal sinuses were scored endoscopically and analyzed statistically. In the 2 weeks after operation, the mucosa scores of sphenoidal sinus (3.5 ± 1.5), ethmoidal sinus (3.6 ± 1.4), maxillary sinus (3.7 ± 1.5), and frontal sinus (3.8 ± 1.5) showed no significant differences by no parameter tests (χ(2) = 1.674, P = 0.643). In the 2, 3, 6, and 9 months postoperatively, the assessment of four kinds of sinuses showed separate transitional tendency and the descending deflection points of scores and ascending peaks of epithelization proportions gradually emerged. In the 12 months postoperatively, by the above statistical methods, the mucosal scores (Z = -3.417, P = 0.001) and epithelization proportions (χ(2) = 4.313, P = 0.038) of sphenoidal sinus were superior to that of ethmoidal sinus, the mucosal scores (Z = -2.218, P = 0.027) and epithelization proportions (χ(2) = 4.292, P = 0.038) of ethmoidal sinus were superior to that of maxillary sinus, and the mucosal scores (Z = -2.244,P = 0.025) and epithelization proportions (χ(2) = 4.100, P = 0.043) of maxillary sinus were superior to that of frontal sinus.</p><p><b>CONCLUSIONS</b>The transitional course of different sinus mucosa after functional endoscopic sinus surgery shows significant time difference. The time sequencing to complete epithelization of sinuses is successively sphenoidal sinus, ethmoidal sinus, maxillary sinus, and frontal sinus.</p>

<p><b>OBJECTIVE</b>This study was focused on the clinical effects of topical steroid for chronic rhinosinusitis (CRS) in Chinese adults.</p><p><b>METHODS</b>The CRS patients were randomly selected in the department of otorhinolaryngology, first affiliated hospital of Sun Yat-sen university between november 2010 and December 2011. Thirty-four CRS patients with polyps (CRSwNP) or CRS without polyps (CRSsNP), no prior surgeries were included. These patients were prescribed to use budesonide nasal spay for three months. Evaluation included visual analog score (VAS), sino-nasal outcome test-20(SNOT-20), CT scan (Lund-Mackay score). SPSS 16.0 software was used to analyze the data.</p><p><b>RESULTS</b>Four patients were lost to follow up, while the other 30 patients finished the 3-months' follow up. Except for smelling disturbance which was not statistically changed (t = 0.902, P > 0.05), VAS for nasal blockage (baseline: 4.84 ± 3.15, after treatment: 2.26 ± 2.27), rhinorrhea (baseline: 6.03 ± 2.93, after treatment: 1.96 ± 2.23), headache (baseline: 1.68 ± 2.66, after treatment: 0.42 ± 0.95), facial pressure (baseline: 2.04 ± 2.97, after treatment: 0.58 ± 1.42) and general symptom (baseline: 6.00 ± 2.75, after treatment: 2.71 ± 1.90) were statistically decreased (t value was 4.386, 6.740, 2.445, 2.980, 6.989, respectively, all P < 0.05). VAS of nasal blockage, rhinorrhea and general symptom were statistically decreased after one-month's treatment (all P < 0.05), but no statistical improvements were observed between first, second and the third month (all P > 0.05). SNOT-20 was significantly decreased after treatment (t = 3.687, P < 0.01). 22.2% patients were cured on CT scan.</p><p><b>CONCLUSIONS</b>Topical steroid improves objective symptoms and quality of life in CRS patients. Some of the patients can be cured in CT scores. The symptoms improvements begin from the first month, but do not change during the latter two months.</p>

<p><b>OBJECTIVE</b>To evaluate the efficacy of endoscopic sinus surgery (ESS)-based on multidisciplinary treatment for patients with chronic rhinosinusitis (CRS) and asthma.</p><p><b>METHODS</b>The study included 25 CRS patients with asthma who received ESS from September 2006 to March 2009, besides surgery, who also used corticosteroid nasal spray, oral macrolide antibiotics and nasal irrigation perioperatively. Evaluation was performed before ESS, 1 year and 3 years post-ESS. Evaluation index included visual analogue scale (VAS) and endoscopy Lund-Kennedy assessment for CRS, and asthma control test (ACT) and pulmonary function tests for asthma.</p><p><b>RESULTS</b>Twenty-three (92%) patients were followed up for 12 months. Twelve (48%) of them were followed up for 36 months. CRS efficacy: VAS of general symptom significantly improved after ESS compared to pre-ESS (8.12 ± 0.60, x(-) ± s), after 1 year (3.20 ± 2.19) and 3 year (3.79 ± 2.32) follow up (both P = 0.000). There was no statistic difference between 1 year and 3 year follow up (P = 0.851). Endoscopy Lund-Kennedy score significantly improved in post-ESS after 1 year (4.35 ± 3.21) and 3 year (5.50 ± 2.64) follow up compared to pre-ESS (9.80 ± 2.10, both P = 0.000), and there was no difference between 1 year and 3 year follow up (P = 0.606). Asthma efficacy: ACT pre-ESS, 1 year and 3 year were 21.96 ± 2.16, 23.61 ± 1.94 and 22.33 ± 3.47, without statistic difference (F = 2.871, P = 0.065). Pulmonary function showed no significant change after surgery (Pre-ESS 74.68 ± 11.09, 1 year 73.27 ± 12.27, 3 year 73.50 ± 7.87, F = 0.076, P > 0.05).</p><p><b>CONCLUSIONS</b>ESS improves CRS with asthma significantly and persistently.

<p><b>OBJECTIVE</b>To evaluate the outcome of mometasone furoate nasal spray (MFNS) used for 3 months on non-allergic rhinitis (NAR).</p><p><b>METHODS</b>In this multicenter study, NAR patients were enrolled from eight hospitals and received MFNS 200 microgram once daily for 3 months. The patients were followed-up for three times (at baseline, month 1 and month 3) to record the symptom scores and nasal endoscopic appearances. At the same time, the adverse events frequency was recorded and analyzed.</p><p><b>RESULTS</b>A total of 188 NAR cases were enrolled in the study. The total nasal symptom score assessment descended significantly at month 1 (1.70 ± 0.75) and month 3 (0.95 ± 0.79) visits versus at baseline (2.67 ± 0.68, Z value were from -11.603 to -10.491, all P < 0.01). The individual symptoms, including nasal stuffiness, nasal discharge, nasal stuffiness-related dizziness or headache, hyposmia, sleep quality, daily life activity, work or study efficiency, mental status, and whole body fatigue, also showed less scores at month 1 and month 3 visits versus at baseline (Z value were from -11.313 to -6.802, all P < 0.01). At the same time, nasal mucosal appearances assessed by endoscopy had lower scores at month 1 (1.40 ± 0.62) and month 3 (0.75 ± 0.71) visits versus at baseline (2.27 ± 0.73, Z value were from -11.484 to -10.002, all P < 0.01). Additionally, adverse events were only observed in 5.3% cases with light rhinorrhagia and nasal dryness. No other side effect was found.</p><p><b>CONCLUSIONS</b>A 3-months administration of intranasal mometasone can effectively and safely improve NAR patients' clinical symptom and nasal mucosal appearances.</p>

<p><b>OBJECTIVE</b>The purpose of this study was to investigate the proper site for enlarging maxillary natural ostium during ESS, and to compare the draining mode of mucociliary transportation system.</p><p><b>METHODS</b>Three groups were designed to observe the differences of tracer agent transported from maxillary sinus to nasal cavity. Normal control group: 30 cases; Trial group A:30 cases, the maxillary natural ostium were radically enlarged by all sides; Trial group B: 30 cases, the maxillary natural ostium were enlarged by reservation of whole inferior edge and cut away anterior and/or posterior edge. The patients in two trial groups were after nasal endoscopic sinus surgery for more than 12 months and the maxillary ostium were well open.</p><p><b>RESULTS</b>Tracer agent was drained from maxillary sinus to nasal cavity by inferior edge (s) of natural ostium in control group. The core area was posterior part of inferior edge. In trial group A, tracer agent was drained out by inferior edge in 4 cases (13.3%), tracer agent drained out by posterior and/or superior edge(s) and then dispersed to ethmoid sinus in 17 cases (56.7%),tracer agent stacked and/or circularly flowed in the maxillary sinus, and could not be transported out in 9 cases (30.0%). In trial group B,tracer agent drained out by inferior edge to middle meatal in all subjects (30/30,100%), and there was no redirection of the mucociliary transportation.</p><p><b>CONCLUSIONS</b>The inferior edge of natural ostium is the main passage of mucociliary transportation system of maxillary sinus. If the inferior edge of maxillary natural ostium reserved, the post-operative drainage of maxillary sinus would be the same as normal ones. Radical removal of all edges of maxillary natural ostium could lead to redirection of mucociliary transportation, only few cases could drain out by inferior edge, most cases drained out by posterior and/or superior edge and then dispersed to ethmoid sinus. In some cases, tracer agent often stacked in the maxillary sinus and could not be drained out. When there was a need to enlarge the maxillary natural ostium in ESS, it should be done in the anterior and/or posterior edge of natural ostium, the inferior edge should not be damaged so as not to interfere the passage of mucociliary transportation system of the maxillary sinus.</p>

<p><b>OBJECTIVE</b>To explore the quality of life (QOL) outcome of patients with chronic rhinosinusitis (CRS) after endoscopic sinus surgery (ESS) and its influencing factors.</p><p><b>METHODS</b>prospective trial was conducted to survey the QOL status of 120 CRS patients undergoing ESS, in contrast that of 200 healthy individuals passing health examination, at the baseline and at 12-months after operation by Medical Outcomes Study Short Form-36 (SF-36) and Sino-Nasal Outcome Test-20 (SNOT-20). QOL changes and its influencing factors were analyzed statistically.</p><p><b>RESULTS</b>(1) By the assessment of SF-36, the scores of 6 domains were less than that of healthy individuals preoperatively (P < 0.01). After 6 months, the scores of these domains resumed normal level and the proportion of scores also restored normally (P > 0.05). (2) By the assessment of SNOT-20, the total scores of 20 items and 5 most important items of patients were more than that of healthy objects (P < 0.01). After 9 and 12 months, the former and latter returned to normal, respectively (P > 0.05). In 12 months setting, the proportion of scores also restored normally (P > 0.05). (3) According to the survey of SNOT-20, we concluded the following equation: convalescent time (months) = 39--(normal scores/preoperative scores) x 50, by which the time of coming back to normal QOL status can be computed. (4) By analysis of Logistic Regression, residence in city or country, course of disease, extension of diseased sinus, and coexistence of nasal polyposis or not were correlated to the preoperative QOL scores; working environments, surgical extension, and preoperative scores of QOL were correlated to the score difference between pre and post operation.</p><p><b>CONCLUSIONS</b>CRS patients undergoing ESS could obtain entirely normal QOL status at 12 months postoperatively, so we suggest that the essential follow-up period should last at least one year. The risk factors influencing patients QOL status preoperatively includes residence in country, longer course of disease, more extension of diseased sinus, and coexistence of nasal polyposis. The risk factors hindering the improvement of QOL status postoperatively includes exposure to indoor working environments, insufficient surgical extension, and lower preoperative QOL scores.</p>

<p><b>OBJECTIVE</b>To develop the Sino-Nasal Outcome Test-20 Chinese Version (SNOT-20 CV).</p><p><b>METHODS</b>By introducing, translating, pretesting, adjusting, and performance testing of SNOT-20 inventory, a Chinese draft scale came into being. On the basis of the clinical applications and feedbacks from ten domestic hospitals, the scale was further modified and was more strictly tested in sixty patients with chronic rhinosinusitis, and then its psychometric properties were compared with that of the original edition.</p><p><b>RESULTS</b>The SNOT-20 CV showed the following psychometric properties: The scale was easily accepted and answered in patients, showing a satisfactory feasibility. The split-half reliability, Cronbach' alpha and intraclass correlation coefficient were 0.95, 0.88, and 0.98, respectively. The content validity was approved by experts of working group. The criteria validity calculated between SNOT-20 and SF-36 was -0.67. Factor analysis of construct validity showed that the comparative fit index was 0.93 and the 20 items were classified into 4 domains which were accorded with the designed constructs. The category rating system was of reasonable additivity and comparability. Every domain was of sensitivity to effectively discriminate between patient population and healthy population (P < 0.01). The standardized response mean of twenty items and five important items at three months postoperatively was respectively 0.48 and 0.57, suggesting moderate responsibility to clinical change. SNOT-20 CV passed the tests of feasibility, reliability, validity, scalability, sensitivity, and responsibility, showing good properties comparable to that of the original edition.</p><p><b>CONCLUSIONS</b>SNOT-20 CV passes the psychometric and clinimetric tests and can be used for measuring rhinosinusitis-specific quality of life in China.</p>

<p><b>OBJECTIVE</b>To assess the subjective and objective outcomes of chronic rhinosinusitis (CRS) following endoscopic sinus surgery (ESS) and establish an assessment system of outcome with ease of application clinically.</p><p><b>METHODS</b>A prospective cohort study was conducted to survey and assess the outcomes of 120 consecutive CRS patients undergoing endoscopic sinus surgery at 12 months after operation. The subjective and objective measures comprised symptom by visual analog scale (VAS), health-related quality of life by medical outcome study short-form 36-items (SF-36) and sino-nasal outcome test-20 (SNOT-20) scales, endoscopic appearance, mucociliary function, and histological findings. The differences of subjective and objective assessments before and after operation were compared by t-test and Chi-Square test and the correlations between the parameters above were analyzed by Spearman correlation analysis.</p><p><b>RESULTS</b>At 12 months after operation, the patients' total scores by VAS, SF-36 and SNOT-20 scales improved significantly beyond the preoperative survey (P < 0.01); there were 85.96%, 77.19% and 83.33% patients with the scores respectively superior to that of preoperation, of which 72.28% subjects benefited simultaneously from these parameters; and a significant correlation was observed among them before and after operation (P < 0.01) where SNOT-20 showed a more compatibility than the other two. At 12 months after operation, the patients' total scores of endoscopic appearance, mucociliary function, and histological findings significantly improved beyond the preoperative evaluation (P < 0.05); there were 86.84% , 86.81% and 75.57% patients with the scores respectively superior to that of preoperation, of which 71.85% subjects benefited simultaneously from these parameters; and a significant correlation was observed among them before and after operation (P < 0.05) where endoscopic appearance showed a more compatibility than the other two. At 12 months after operation, 74.56% patients showed an accordant improving or worsening outcome evaluated by SNOT-20 and endoscopic appearance, while 25.44% ones represented inverse endings, of which patients with comorbidity of nasal polyps more easily demonstrated this tendency significantly (P < 0.05). No significant correlation existed between the scores of SNOT-20 and endoscopic appearances both in preoperation and in postoperation (P > 0.05), but the total scores of the anterior 10-item, excluding the posterior 10-item, of SNOT-20 inventory was found significantly correlated with the quantitative appearances on nasal endoscopy throughout (0.18 < or = 0.42, P < 0.05).</p><p><b>CONCLUSIONS</b>Administration of ESS can effectively improve the outcomes of CRS patients including symptom, health-related quality of life, endoscopic appearance, mucociliary function, and histological findings. A subjectively and objectively measured assessment system with tenseness, trustiness, reasonableness, and effectiveness and with ease of application clinically is established on the basis of SNOT-20 and endoscopic appearance evaluation for outcome research.</p>

<p><b>OBJECTIVE</b>To search the evidence for the presence of superantigen of Staphylococcus aureus enterotoxin (SE) in the pathogenesis of nasal polyposis.</p><p><b>METHODS</b>In a cohort of population composed of 42 cases who belonged to three groups: nasal polyposis, simple chronic rhinosinusitis (CRS), and control group without any rhinopathy, detecting the specific IgE against SE-A and B (SEA and SEB), total IgE (TIgE), eosinophilic cationic protein (ECP) of the local mucosa by means of FRAST (UniCAP system), as well as the serum TIgE, and serum anti-SEA and SEB SIgE (only in 8 cases); meanwhile the secretion culture was performed for aerobic bacteria from the middle meatus.</p><p><b>RESULTS</b>There was no evidence to support that SE played as a superantigen in all mucosa samples (42 cases) and 8 cases serum samples out of the 42 patients. The range of TIgE in mucosa was 4.59 -70.21 kIU/2 mg tissue protein, the mean was (17.85 +/- 14.31) kIU/2 mg tissue protein; in serum the total IgE was 7.44 - 344.00 kIU/L, the mean was (88.65 +/- 80.03) kIU/L The positive culture of Staphylococcus aureus was obtained from only 3 cases from secretion of middle meatus (1 from nasal polyps, 2 from CRS). There was no significance statistically among the three groups on the tissue fluorescence value of SIgE for SE, the means of tissue TIgE and ECP.</p><p><b>CONCLUSIONS</b>No evidence was found to support the role of SE acting as a superantigen among our cases who did not have persistent asthma. It is suggested that further study and investigation is required to prove the superantigen Hypothesis in the pathogenesis of NPs.</p>

<p><b>OBJECTIVE</b>To explore the health-related quality of life (QOL) status of patients with chronic rhinosinusitis and nasal polyps.</p><p><b>METHODS</b>One hundred and twenty patients with chronic rhinosinusitis and nasal polyps and two hundred individuals passing health examination were enrolled by random and their QOL scores were assessed by using QOL instruments including existing SF-36 questionnaire (Chinese version ) and SNOT-20 questionnaire translated into Chinese, of which clinimetric and psychometric properties were tested.</p><p><b>RESULTS</b>The feasibility, reliability, validity, and responsibility of Chinese version of SNOT-20 questionnaire all passed the test. By the assessment of SF-36 questionnaire, it revealed that scores of six domains such as physical functioning, role physical, bodily pain, mental health, vitality, and general health from patients with chronic rhinosinusitis and nasal polyps were lower than that of control group except social functioning and role emotional (P < 0.05). It showed by Chinese version of SNOT-20 questionnaire that patients exceeded healthy individuals in the scores of twenty items of three domains including physical problems, functional limitations, and emotional consequences, of which the most five important items affecting health status were respectively need to blow nose, thick nasal discharge, lack of a good night's sleep, dizziness, and post-nasal discharge (P < 0.05).</p><p><b>CONCLUSIONS</b>QOL instruments such as Chinese version of SF-36 and SNOT-20 questionnaires can effectively differentiate the QOL status between patients with chronic rhinosinusitis and nasal polyps and healthy individuals. The negative impact of chronic rhinosinusitis and nasal polyps on patients' QOL includes physical functioning, role physical, bodily pain, mental health, vitality, general health, and emotional consequences. The problems of nasal discharge, sleep, and dizziness should be sufficiently emphasized in clinical treatment.</p>

<p><b>OBJECTIVE</b>The purpose of this article is to establish an endoscopic score system for quantitative evaluation of the inflammation of mucous membrane in patients with chronic rhinosinusitis (CRS) , and to investigate the correlation of this system with a variety of clinical factors.</p><p><b>METHODS</b>A set of score system was constructed based on anatomic configuration, status of mucous membrane and nasal secretion to evaluate quantificationally the severity of inflammation of CRS. The clinical correlation of this system was studied prospectively in 60 CRS patients, with a variety of clinical factors which included age, duration of disease, previous recurrence and the years from recent recurrence, atopy, serum total immunoglobulin E (TIgE), serum eosinophil cationic protein (ECP), the count of blood eosinophil, the count of tissue inflammatory cell, the extension of CRS indicated by CT, smoking, concomitant chronic inflammation in lower respiratory tract. All above factors were analyzed statistically with the endoscopic score by Pearson correlation and multi-factor linear regression analysis.</p><p><b>RESULTS</b>In pearson analysis, the correlative factors with the evaluated score included age (x1, r = - 0.310, P = 0.016), the extension of disease (x2, r = 0. 810, P < 0.0005), recurrence (x3, r = 0.408, P = 0.001), eosinophil of nasal tissue (x4, r = 0.279, P = 0. 031), duration of disease (x5, r = 0.536, P < 0.0005), concurrent nasal polyps (r = 0.549, P < 0.0005), plasm cell (r = 0. 317, P = 0.014) and years from the recent recurrence (r = 0.385, P = 0.002). In multi-factor linear regression, the five independent predictive factors were recurrence, age, extension of disease, tissue eosinophils, years of disease. The regressive equation is y = 10.148 - 0.152 (x1) + 2.250 (x2) + 3.348 (x3) + 1.233 (x4) + 0.270 (x5).</p><p><b>CONCLUSIONS</b>Appropriate score system by nasal endoscopy is feasible to evaluate quantificationally the degree of inflammation of CRS; being appropriately modified, it is even able to reveal the underlying histological behavior finely.</p>

<p><b>OBJECTIVE</b>To explore the characteristics of bacteria isolated from patients with chronic sinusitis (CR) and antibiotic-resistance.</p><p><b>METHODS</b>The purulent discharges taken from the maxillary sinus and posterior ethmoid sinus of 76 patients during endoscopic sinus surgery were cultured for both bacteria and fungi, then the antimicrobial susceptibility test and beta-lactamase-producing bacteria (beta-LPB) were detected. In the control group, the discharges from the nasal cavity from 10 healthy adults were also cultured for bacteria.</p><p><b>RESULTS</b>Twenty species, including Staphylococcus epidermidis, Escherichia coli, Staphylococcus aureus, alpha-Hemolytic streptococcus and Streptococcus pneumoniae, were cultured from the testing group. The total positive rate of bacteria was 81.8%. The detectable rates of aerobe, anaerobe, gram-positive bacteria and gram-negative bacteria were 83.4%, 16.6%, 56.3% and 43.7%, respectively. The fungi was only detected in 1.4% patients. The antimicrobial susceptibility test demonstrated that Imipenem, Cefotaxime and Amoxicillin-clavulanate were good in vitro activity to aerobic pathogens and Metronidazole, Imipenem and Chloramphenicol was good to anaerobic pathogens. The beta-LPB was detected in 37.7% strains in which Staphylococcus epidermidis, Staphylococcus aureus, alpha-Hemolytic streptococcus and Branhamella catarrhalis were more frequent. Five species including Staphylococcus epidermidis and Escherichia coli etc were cultured from the control group. There was no significant difference of distribution of the same bacteria between the control group and the testing group (P > 0.05).</p><p><b>CONCLUSIONS</b>The pathogenic bacteria of CR mostly involve aerobes. The antibiotics-resistance of these pathogen is serious. The bacterial infection plays no leading role in CR, so the need of antibiotics should not be excessively emphasized. Before treatment by antibiotics, the antimicrobial susceptibility test should be performed. The broad-spectrum antibiotics containing beta-lactamase inhibitor such as Cefotaxime and Amoxicillin-clavulanate is recommended in condition that the test can not be finished.</p>
