Objective To evaluate the diagnostic value of shear wave elastography(SWE)and Breast Ima-ging Reporting and Data System -Ultrasonograpy(BI -RADS -US)in benign and malignant breast lesions.Methods 180 patients with pathological -confirmed benign and malignant breast lesions without any treatment were underwent ultrasonography scoring with BI -RADS and the quantitative elasticity parameters was measured by shear wave elastography 1week before operation.Pathological results were regarded as the gold standard,receiver operating characteristic curve(ROC)was used to determine cutoff values of quantitative parameters and diagnostic performance of two methods.Results Maximum elastic value(Emax)and mean elastic value(Emean)of benign breast lesions were (39.17 ±11.48)kPa and (21.56 ±9.68)kPa,which were significantly lower compared with the malignant breast lesions of (121.38 ±28.97)kPa and (62.92 ±18.49)kPa,respectively(t =23.668,P =0.000;t =18.194, P =0.000).Taking 43.79kPa and 65.15 kPa as the threshold of the Emean and Emax value,the sensitivity,specificity and accuracy of SWE were 92.59%,90.78% and 94.84%,respectively.The areas under the curve(AUC)of the SWE and BI -RADS -US were 0.942 and 0.883 (P =0.042).Conclusion SWE can improve the accuracy of ultrasonography in differentiation of benign from malignant breast lesions by quantitative elasticity parameters,which has important significance for clinical treatment.

Objective To investigate the value of contrast enhanced ultrasound (CEUS) in diagnosing metastatic adrenal carcinoma. Methods Twenty two metastatic adrenal carcinoma lesions in 18 patients were examined using CEUS. The features and detected rate of gray scale and CEUS were analysed and compared. Results Fourteen lesions of metastatic adrenal carcinoma were detected by two dimensional ultrasonography(2DU), the detected rate of 2DU was 58. 3%. While 20 lesions were detected by CEUS, the detected rate was 83. 3%. There was a significant difference of detected rate between 2DU and CEUS (P<0.05). The adrenal metastatic carcinomas were enhanced rapidly with the peek intensity slightly low or same to the surrounding liver or renal parenchyma. The lesions number, size and range were clearly presented by CEUS. Conclusions CEUS can markedly improve detected rate of metastatic adrenal carcinoma compared with 2DU.

Objective To explore the developmental tendency of eco-migrant children's extroversive behavior and the relationship between extroversive behavior and personality and family environment.Methods 856 eco-migrant children(aged 6-16)participated in the present longitudinal study.At first time the Child behavior checklist(CBCL),Eysenck personality questionnaire (EPQ) and Family environment scale (FES) were used to assess their behavioral problems,personality and family environment.Participants' parents subsequently completed measures assessing behavioral problems every nine months for 27 months.Data were analyzed using hierarchical linear modeling analyses.Results The scores of extroversive behavior in eco-migrant children were(10.09±7.11) at first time,(7.66±7.56) at the second wave,(8.54±7.49)at the third wave and(8.11±7.33) at the last time.During the longitudinal period,the descending trend of eco-migrant children's extroversive behavior was significant (β=-0.51,P＜0.05).The scores of psychoticism,neuroticism,family conflict,organization,cohesion and cultural factors were differently correlated with children's extroversive behavior (β=-0.67-0.32,P＜0.05).Family conflict predicted the developmental trend of children's externalizing (β=-0.46,P＜0.05).Conclusion During the longitudinal period,the level of eco-migrant children's extroversive behavior decreased,and personality and family environment have significant influences on it.

Objective To assess the value of hysterosalpingo-contrast-sonography (HyCoSy) with the contrast agent SonoVue in the diagnosis of women infertility. Methods Thirty-six cases of infertility underwent HyCoSy using SonoVue and compared with laparoscopie hydrotubation. Resnlts Among 69 fallopian tubes,22 of them were diagnosed to be obstructive by HyCoSy. Compared with laparoscopic hydrotubation, the sensitivity and specificity of HyCoSy were 90. 5 % and 93.8 %, respectively. Conclusions HyCoSy is a convenient, non-invasive, non-radiative method,which may be regarded as an effective tool to assess the fallopian tubes in patients with infertility.

Objective To evaluate the value of contrast-enhanced ultrasound and ultrasonic elastography in the diagnosis of breast lesions with BI -RADS Ⅲ -Ⅴ.Methods 169 patients with BI -RADS Ⅲ -Ⅴ breast lesions were underwent contrast -enhanced ultrasound and ultrasonic elastography 1 week before surgery.Pathological findings were used as the gold standard to evaluate the diagnostic accuracy of contrast -enhanced ultrasound and ultrasonic elastography in diagnosis of BI -RADS Ⅲ -Ⅴ breast lesions.Results The combination of contrast -enhanced ultrasound and ultrasonic elastography in diagnosis of BI -RADS Ⅲ -Ⅴ breast lesions,with the sensitivi-ty,specificity and accuracy of 96.15%,94.34%,and 95.11%,respectively.The difference was statistical signifi-cance compared with single method(χ2 =4.659,P =0.032,χ2 =4.146,P =0.041).Conclusion The combination of contrast -enhanced ultrasound and ultrasonic elastography improves the diagnostic accuracy of Ⅲ-Ⅴ breast lesions.
