Objective To investigate the diagnostic value of hyperenhancement sign on ultrasound,CT and their combination in diagnosis of thyroid benign and malignant nodules.Methods The contrast-enhanced ultrasound and enhanced CT datas of 172 thyroid nodules in 144 cases confirmed by operation and pathology were retrospectively analyzed,including 97 benign nodules and 75 malignant nodules.According to the degree of enhancement,these nodules were divided into iso-or low-enhancement and hyperenhancement.The distributions of ultrasound hyperenhancement,CT hyperenhancement and both of them in thyroid benign and malignant nodules,adenomatoid lesions and nodular goiters were analyzed,followed byx2 test for statistical analysis.Results In 172 thyroid nodules,the proportions of ultrasound hyperenhancement,CT hyperenhancement and both of them in thyroid benign and malignant nodules were 53.6％(52/97) and 20.0％(15/75)(x2＝20.090,P＜0.05),34.0％ (33/97) and 4.0％ (3/75) (x2＝23.033,P＜0.05),31.0％ (30/97) and 0％ (0/75) (x2＝28.096,P＜0.05),respectively.Their sensitivity and specificity of diagnosing benign nodules were 53.6％ (52/97) and 80.0％ (60/75),34.0％ (33/97) and 96％ (72/75),30.9％ (30/97) and 100％ (75/75),respectively.The proportions of ultrasound hyperenhancement,CT hyperenhancement and both of them in adenomatoid lesions and nodular goiters were 96.9％(31/32) and 32.3％(21/65)0x2＝35.946,P＜0.05),65.6％(21/32) and 18.5％(12/65)(x2＝21.250,P＜0.05),65.6％(21/32) and 13.8％ (9/65)(x2＝26.912,P＜0.05).Their sensitivity and specificity of diagnosing adenomatoid lesions were 96.9％(31/32) and 67.7％(44/65),65.6％(21/32) and 81.5％(53/65),65.6％(21/32) and 87.2％(56/65).Conclusions Ultrasound hyperenhancement,CT hyperenhancement for diagnosing thyroid benign nodules are of significant value.Especially for adenomatoid nodules,ultrasound hyperenhancement has a higher sensitivity,while CT hyperenhancement has a higher specificity.Their combination can further improve the diagnostic specificity,thus reducing the unnecessary surgical trauma.

Background:Helicobacter pylori( Hp)is listed as Group 1 human carcinogen. Transcription factor FOX family plays important role in the development of tumor,and FOXA1 is a key target transcription factor of some microRNAs( miRNAs). Aims:To investigate the relationship of Hp infection with expression of FOXA1 in gastric mucosal tissues. Methods:Eighty patients undergone gastroscopy from Jan. 2014 Sept. 2014 were enrolled. Hp infection was detected by 14 C-urease breath test( 14 C-UBT),modified Giemsa staining and bacterial culture. Expression of FOXA1 in gastric mucosal tissues was determined by immunohistochemical SP method. Results:FOXA1 expression in Hp positive tissues was significantly higher than that in Hp negative tissues(73. 8% vs. 47. 4%;χ2 =4. 81,P<0. 05). Conclusions:High expression of FOXA1 in gastric mucosal tissues suggests that miRNAs pathway may be one of the molecular mechanisms of Hp infection leading to gastric intraepithelial neoplasia even gastric cancer.
