Objective To evaluate the association of the size of thyroid nodules and accuracy of fineneedle aspiration cytology in diagnose of thyroid nodules.Methods 691 thyroid nodules in 630 patients pathologically confirmed were retrospectively analyzed in our hospital.All imaging data of preoperative ultrasound-guided FNAC were collected in our review.Yields of FNAC were divided into six levels according to the classification criteria of the Bethesda system(level Ⅰ,insufficient material or nondiagnosed;level Ⅱ,benign ; level Ⅲ,atypical hyperplasia; level Ⅳ,follicular neoplasm ; level Ⅴ,suspicious for malignancy; level Ⅵ,malignant),＞level Ⅳ was the malignant cytologic criteria for diagnosis of thyroid nodules.According to the maximal diameter of thyroid nodules,the nodules were divided into group A(L≤0.5 cm),group B(0.5 cm＜L＜1.0 cm) and group C(L≥1.0 cm).Postoperative pathologic results were taken as the gold standard.Results Of 691 nodules,there were 176(25.47％),298(43.13％) and 217(31.40％) in group A,group B and group C respectively.Among the three groups,accuracy of ultrasound-guided FNAC in group B (90.94 ％) was higher than in group A(80.11％) and group C(83.41 ％),with statistically significant(P ＜0.05).There was not statistically different between group A and group C(P ＞0.05).The specificity,positive predictive value and negative predictive value were not statistically different among three groups(P ＞0.05).Conclusions The size of thyroid nodules was partly associated with accuracy of ultrasound-guided FNAC.

Objective To investigate the relationship between bacteria biofilm and bacterial culture in patients with chronic rhinosinusitis (CRS). Methods Ninety patients with CRS were enrolled in the study. Five patients with deviation of nasal septum and 10 healthy subjects served as controls. Mucosa of uncinate process or near the ostium of the maxillary sinus was obtained during endoscopic sinus surgery. All specimens were processed for bacterial culture and scanned by electron microscopy. Pearson test was performed to analyze the relationship between the presence of bacterial biofilm and the results of bacteria culture. Results The scanning electron microscopy showed bacterial biofilms in 64 (71.1%) out of 90patients with CRS, while the positive rate of bacteria culture in the study group was 66.7% (60/90). No bacterial biofilm and bacterium was detected in the control group and 26 culture-negative individuals in study group. Pearson correlation analysis showed a statistically association between bacterial biofilm and bacterial culture in CRS ( r = 0. 901, P = 0. 000). Conclusion Positive results of bacteria culture are highly correlated with the presence of bacterial biofilm in CRS patients.
