Objective To compare the two-dimensional (2D) and three-dimensional (3D) shear wave elastography (SWE) technology in the diagnosis of early stage breast cancer.Methods 84 patients (94 breast lesions) with breast disease confirmed by pathological examination were enrolled from December 2014 to December 2016.All patients underwent 2D and 3D color Doppler ultrasound and the relevant SWE examinations.The optimal maximum and mean elastic modulus of 2D and 3D SWE for diagnosing the benign and malignant breast lesions were obtained by the receiver operating characteristic curve (ROC).Based on the results of pathological examinations,the sensitivity,specificity and accuracy of 2D SWE and 3D SWE in benign and malignant breast lesions diagnosis were evaluated and compared.Results The optimal maximum and mean elastic modulus of 2D SWE for diagnosing the benign and malignant breast lesions were 98.82 kPa and 43.88 kPa respectively,while the corresponding modulus of 3D SWE were 102.54 kPa and 53.87 kPa.The sensitivity of 2D SWE and 3D SWE in breast cancer diagnosis was 89.5％ and 86.3％ respectively,and the difference was not statistically significant (P＞0.05).The specificity and the accuracy of 2D SWE in breast cancer diagnosis were 95.3％ and 92.7％ respectively,which was significant higher than 83.9％ and 85.1％ of 3D SWE,and the differences were statistically significant (all P＜O.05).Conclusions The efficiency of 2D SWE examination is significantly higher than the 3D SWE in benign and malignant breast lesions diagnosis,which can provide a reliable diagnostic basis and is worthy for clinical application.

Objective To design and prepare an RNA interfering vector for effectively inhibiting the cellular expression of zinc finger protein A20 and observe the effect of A20 gene silence on cellular inflammatory response. Methods Specific RNA interfering oligonucleotide fragments (ASRF) were designed and synthesized artificially and the A20 RNA interfering vector pSUPER-EGFP-A20 siRNA constructed. Human monocyte cell line THP1 was used to infect the pSUPER-EGFP-A20 siRNA by means of genetic transfection technique; then, silence rate of cellular A20 was analyzed by real-time polymerase chain reaction (PCR). In the meantime, the activity of nuclear transcription factor nuclear factor-κB (NF-κB) and the level of tumor necrosis factor-α (TNF-α) in culture supernatant were measured by ELISA. Results Of two specific inhibitory oligonueleotide fragments of A20, the fragment M59465-385R/F had a higher inhibition to A20 expression, with rate of A20 gene silence of 83.86%. Preliminary application showed that after A20 gene silence, the activity of NF-κB was increased by 78.13% and the level of TNF-α in cell culture supernatant was increased by 49.30%. Conclusions Vector of A20gene silence with a high efficiency is obtained successfully. Preliminary application indicates that the expression of A20 can down-regulate the degree of cellular inflammatory responses.

Objective To explore the normal range of the volume of frontal lobe in Chinese adults of the Han nationality and provide morphological data for the construction of database for Chinese Standard Brain. Methods This is a clinical multi-center study. Two hundred Chinese healthy volunteers (age range= 18 to 70) recruited from 16 hospitals were divided into 5 groups, i. e. , age range from 18 to 30, age range from 31 to 40, age range from 41 to 50, age range from 51 to 60, and age range from 61 to 70. Each group contained 20 males and 20 females. All of the volunteers were scanned by MR using T1 weighted threedimensional magnetization prepared rapid acquisition gradient echo sequence. We used the manual method to trace the region of interest and measured the left and right frontal lobe volumes separately. All the data were analyzed with SPSS (version 13.0). The sex differences in the frontal lobe volumes were analyzed by independent-samples t test, and the side differences were analyzed by paired-samples t test. Correlation and regression analysis was used between the age and the frontal lobe volumes. Results In 200 healthy Chinese Han volunteers, the total frontal lobe volumes was (563 ± 73) cm3. For male, the volumes of the left and the right frontal lobe were (288±42) cm3 and (292 ±41 ) cm3 ,respectively. The volumes of the left and right frontal lobe in 100 women were (273 ±30) cm3 and (274 ± 30) cm3 respectively. The differences of sex (t = 3. 334, P < 0. 05 ) and side ( t = - 3.09, P < 0. 05 ) in the total frontal lobe volumes reach significant. There was no significant differences in women ( t = - 1. 304, P > 0. 05 ). There were negative correlations between the frontal lobe volumes and age in men and women ( r = - 0. 586, - 0. 498, P <0. 01 ). Conclusions The total frontal lobe volume of men was larger than that of women. The volume of the right frontal lobe was larger than the left frontal lobe in men, and the asymmetries didn't exist in women.The total frontal lobe volumes were both shrinking with age in men and women, which was more rapid in men than in women.

Objective To study the value of breast imaging reporting and data system (BI-RADS)in Chinese breast cancer screening. Methods A total number of 3483 women participated in breast cancer screening with mammography in Hexi district in Tianjin from August to December 2009, which was organized by ministry of public health. BI-RADS assessment categories and recommendations were compared with histological findings. The precision, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results Among 3483 screening mammography cases, 267 were almost entirely fat breast, 1245 were scauered fibroglandular, 1890 were dense and 81 extremely dense.There were 1011 patients(29.0%) with category 1, 1741 (50.0%) with category 2, 383 (11.0%) with category 3, 59 patients(1. 7%) with category 4 and 16 (0. 5%) with category 5 according to BI-RADS assessment categories. Totally, 71 women with 77 lesions were confirmed by histological examinations. There were 29 malignant and 48 benign lesions. The diagnostic precision, sensitivity, specificity of BI-RADS were 63. 6% (49/77) , 93. 1% (27/29) and 45.8% (22/48) . The general PPV of BI-RADS was 50. 9%(27/53). The PPV of categories 0, 4, 5 were 25.0% (1/4), 36. 4% (12/33) and 87. 5% (14/16). The NPV of categories 2 and3 were90.9% (10/11), 100.0% (12/12).

OBJECTIVE To explore the characteristics of cochlear hair cell injuries in guinea pigs exposed to blast underpressure(BUP). METHODS The guinea pigs were killed 14 days after exposure to experimental BUP. Their basilar membranes were stained by silver nitrate and the hair cell injuries were quantitatively assessed using the light microscope. RESULTS The outer hair cells(OHCs) of the guinea pigs clearly appeared to be injured following exposure to the experimental BUP at a peak underpressure varying between -22.4kPa and -63.3kPa. The most obvious injury was in the second turn and OHC loss was smallest in the first row and more severe in the second and third rows. OHC loss was seen in all of three experimental groups of animals following exposure to BUP. Furthermore, the higher the peak of underpressure, the more obvious the injury of OHCs. Quantitative morphological analysis of cochlear hair cells showed that the total OHC loss rates in all the experimental groups of guinea pigs exposed to BUP were significantly higher than that of control group animals(P
