OBJECTIVE: To study the correlation between the bacterial biofilm formation and bacterial culture in chronic otitis media. METHOD: As a prospective reserch, we used scanning electron microscopy to examinate patients samples which collected from 32 cases of patients with chronic suppurative otitis media and middle ear cholesteatoma in the operations, and performed the middle ear secretions bacterial culture. According to the different types of chronic otitis media group, we analysised the relationship between chronic otitis media bacterial biofilm formation and the bacterial culture results. RESULT: Chronic suppurative otitis media (activity) and middle ear cholesteatoma bacterial biofilm formation rate were 87.5%, 81.3%, chi-square (P > 0.05). Compared bacterial biofilm results with the results of bacterial cultured in chronic otitis media, sensitivity was 70.37%, specificity was 60.00%, the misdiagnosis rate was 40.00%, the missed diagnosis was 29.63%, positive predictive value was 90. 46%, negative predictive value was 27.27%, accuracy was 68.75%. Youden index was 30. 37%, and Pearson correlation coefficient was 0.232 (P > 0.05). CONCLUSION Chronic suppurative otitis media (activity) and middle ear cholesteatoma bacteria had a higher biofilm formation rate. The routine bacterial culture results can't reflecte bacterial biofilm formation in chronic otitis media. We need to explore more reliable experimental methods to accurately reveal the infection status of chronic otitis media.

OBJECTIVE To evaluate the clinical features of tumors primarily in the pterygopalatine fossa, and the efficiency of surgical management for these lesions. METHODS The clinical data of 7 cases with tumors primarily in the pterygopalatine fossa were retrospectively studied. Three of them were primary diseases, i.e. fibrous histiocytoma, neurofibroma and cholesteatoma. The other 4 cases were secondary tumors mainly located in pterygopalatine fossa. There were 1 case with epithelial-myoepithelial carcinoma, 1 case with adenoid cystic carcinoma , 1 case with recurrent inverted nasal papilloma, 1 case with recurrent malignant fibrous histiocytoma. Approaches to tumors in pterygopalatine fossa lesions included lateral rhinotomy, and transnasal or transantrum approaches under the nasal endoscope. RESULTS The patient suffered from adenoid cystic carcinoma developed local recurrence 4 months after operation, and extended resection of the recurrent tumor with laser was performed again. No further recurrence was found after following-up for 3 years. Neither local recurrence nor regional metastasis was found in the remaining 6 cases with a follow-up period of 2 to 4 years. The main complication was oronasal fistula. CONCLUSION CT scan or MRI is the main method to the early diagnosis of pterygopalatine fossa tumors. Lateral rhinotomy, endoscopic trasnnasal or transantrum approaches are feasible procedures to resect the tumors.

Objective Dilated cardiomyopathy (DCM) is generally considered to be accompanied by both left and right ventricular dysfunction,but most studies only analyze the left ventricular function. In this study, we evaluated the effect of arotinolol on right ventricular function in patients with DCM. Methods Right ventricular ejection fraction (RVEF) and right ventricular diameter (RVD) were measured by two-dimensional echocardiography (2-DE) in 33 DCM patients; RVEF measured by first-pass radionuclide angiography (FPRA) was compared with that by 2-DE. Results The treatment with arotinolol for one year resulted in a reduction in the right ventricular diameter (baseline, 23.0 ± 8.3 mm vs after one-year treatment, 20.7 ± 5.4 mm; P=0.004 ) and an associated increase in ejection fraction (baseline, 36.9 ± 10.3% vs after one-year treatment, 45.8 ± 9.6%; P ＜ 0.001 ); there is a high correlation between the 2-DE method and radionuclide ventriculographic method. The correlation coefficient is 0.933 (P＜0.001). Conclusion Arotinolol therapy could not only improve left ventricular function, but also improve right ventricular function in DCM patients.

Objective:To analyze the serum levels of integrin-associated proteins (CD47) in patients with rheumatoid arthritis (RA), and to explore its association with disease activity and bone destruction in RA.Methods:Serum and clinical data were collected from 65 RA patients and 25 healthy subjects. RA patients were grouped into low, moderate, and high bone erosion groups according to 7-joint ultrasonography score (US7). The levels of serum CD47, thrombospondin-1 (TSP-1) and receptor activator of nuclear factor-κB ligand (RANKL) were measured by enzyme-linked immunosorbnent assay (ELISA) in patients with RA and healthy subjects. The statistical analysis was carried out with independent t-test, analysis of variance, nonparametric rank sum test, pearson or Spearman correlation and logistic regression. Results:① The Serum levels of CD47, TSP-1, and RANKL were higher in the RA group than in the healthy controls ( P<0.01). ② In RA patients, serum CD47 level was positively correlated with disease course ( r=0.301, P<0.05), C-reactionprotein (CRP)( r=0.316, P<0.05), number of tender joints (TJC) ( r=0.254, P<0.05), number of swollen joints (SJC) ( r=0.316, P<0.05), disease activity score in 28 joints (DAS28) ( r=0.255, P<0.05), RANKL ( r=0.252, P<0.05) and TSP-1 ( r=0.260, P<0.05). Serum TSP-1 level was positively correlated with CRP ( r=0.299, P<0.05), TJC ( r=0.335, P<0.01), DAS28 ( r=0.315, P<0.05), RANKL ( r=0.305, P<0.05). ③ The disease course [ OR(95% CI)=1.048(1.033, 1.017)] and TSP-1 [ OR(95% CI)=1.013(1.000, 1.026)] were independently relevant factors affecting bone destruction. Conclusion:CD47 levels is significantly higher in RA patients than in healthy controls, and is associated with disease activity and bone destruction. CD47 may be involved in the bone destruction process of RA by acting on TSP-1.
