Objective To investigate the effect of Shugan-Yishen formula on Tamoxifen-resistant MCF-7 cell line(LCC9) through HER2-ERK/MAPK-ERα pathway. Methods Four serums were prepared with the method of serum pharmacology:the serum of Shugan-Yishen formula, Shugan-Yishen formula plus Tamoxifen(TAM), blank and TAM alone. After LCC-9 cells were affected in the above-mentioed serums in vitro, the inhibition rate and the level of mRNA as well as the protein expression of HER2, ERα, ERK/MAPK, p-ERK/MAPK were detected. Results MTT showed that TAM alone group、Shugan-Yishen formula group and the Shugan-Yishen formula plus TAM group had higher inhibition rates at 48th hour, the inhibition rates was(6.61±0.129)%, (47.43±2.24)%, (54.19±3.364)%, compared to the blank group, Shugan-Yishen formula group and the Shugan-Yishen formula plus TAM group had a stronger inhibition on LCC9 at 48th hour (P<0.05), and the combination group was better than Shugan-Yishen formula alone(P<0.05), there was no difference between TAM group compared to the blank group(P>0.05). RT-PCR result showed that compared to the blank group, the expression levels of ESR1 mRNA of group of Shugan Yishen formula plus TAM werehigher by and large at 48th hour (P<0.05), the expression of ESR1 mRNA was(2.282±0.185);and the levels of ERBB2, MAPK3 mRNAwere lower(P<0.05), which levels were(0.71±0.095), (0.336±0.058). Western blotting result showed that Shugan-Yishen Formula plus TAM group could markedly decrease the expression of HER2, p-ERK/MAPK of LCC9 at 48th hour (P<0.05), which the expressions were(0.708± 0.072), (0.228±0.034), and the expression of ER-αelevated(P<0.05). There was no significant difference on ERK/MAPK(P>0.05). Conclusions ①The combination of Shugan-Yishen formula with tamoxifen can inhibit the LCC9 cells. The inhibition effect reaches the peak at 48th hour. ②The mechanism of Shugan-Yishen formula plus TAM combination effects on human breast cancer TAM-resistant cell line LCC9 may improve the sensitivity of ERαby inhibiting the expression of HER2, ERK/MAPK.

ObjectiveTo investigate the influence of different depths and mediums on tissue stiffness measurement by virtual touch tissue quantification technology.Methods Four kinds of in vitro porcine tissue were recruited,three (fat,muscle and liver) were assigned as medium group and three (kidney,liver and muscle) as sample group.The shear wave velocity (Vs) of the samples was measured under different mediums and at different depths (2 cm,3 cm,4 cm and 5 cm),respectively.ResultsAccording to the depth of measurement,two groups of Vs were defined with one group at the depth of 2 cm and 3 cm while the other at 4 cm and 5 cm.The difference of Vs between the two groups was of statistical significance and with the increase of the depth Vs values decreased.Even at the same depth,the differences of Vs under different mediums were statistically significant.ConclusionsDepths and mediums have great influence on evaluating elasticity measurements by virtual touch tissue quantification technology.

Objective To compare and analyze the similarities and differences of the blood perfusion characteristics of the renal pelvic carcinoma displayed by contrast-enhanced ultrasonography(CEUS) and contrast-enhanced computed tomography(CECT).Methods The characteristics of CEUS and CECT were anzlyzed retrospectively in 40 confirmed renal pelvic carcinoma cases by operation and pathology.The modality and phases of enhancement,including wash-in and washout time,as well as the perfusion appearances,were observed by CEUS and CECT.Results CEUS detected the cortical phase enhancement in all renal pelvic tumors,including synchronously enhancement in 14 tumors and delayed enhancement in 26 tumors.At peak times,hypoechogenicity compared to the normal renal cortex was shown in 31 tumors,hyperechogenicity in 4 tumors and isoechogenicity in 5 tumors.Fast wash-out in medulla phase was displayed in 35 tumors,isochronously wash-out in 2 tumors and delayed wash-out in 3 tumors.The minimum diameter in 40 renal pelvic tumors was 1.5 cm.CECT showed the enhancement in 38 tumors,mostly mild to moderate homogeneous enhancement,and enhancement was lower than the surrounding renal parenchyma.The diagnostic accuracy of CEUS was 77.5% (31/40),and the diagnostic accuracy of CECT was 82.5 % (33/40).The difference was not statistically significant between CEUS and CECT ( P >0.05).Conclusions CEUS and CECT have higher diagnostic accuracy of the renal pelvic carcinoma,so the joint detection can increase the detection rate of early diagnosis of the renal pelvic carcinoma.

Objective To investigate the features of quantitative analysis and parametric imaging of contrast-enhanced ultrasound (CEUS) in renal clear cell carcinoma (ccRCC).Methods Ninety-seven pathologically confirmed ccRCCs underwent conventional ultrasound and CEUS.Both quantitative parameters and dynamic vascular pattern (DVP) reconstructure were analyzed with Sonoliver software.Four types of DVP curves were described with type Ⅰ (Unipolar +),type Ⅱ (Bipolar + /-),type Ⅲ (Bipolar -/+) and type Ⅳ (Unipolar-),while the DVP parametric images,similarly,were divided into four types,with type Ⅰ,Ⅱ,Ⅲ and Ⅳ,respectively.Results As for the parameter of CEUS,there were statistical differences in maximum intensity (IMAX),area under the curve (AUC) and mean transit time (mTT) (P <0.05) and no statistic differences in rise time (RT) and time to peak (TTP) between ccRccs and peripheral renal parenchyma.Concerning of DVP of ccRCCs,type Ⅰ,Ⅱ,Ⅲ and Ⅳ accounted for 58.8% (57/97),11.3% (11/97),10.3% (10/97) and 19.6% (19/97) respectively.As for each type in DVP parametric images,the percentages were 58.8% (57/97),11.3% (11/97),8.2% (8/97),21.7% (21/97),respectively.Conclusions Quantitative analysis and parametric imaging can depict different features of vascularity in ccRCCs and improve the diagnosis of the tumors.

Objective To investigate the enhancement features of hepatic tumors between dynamic three-dimensional contrast-enhanced ultrasonography (3D-CEUS) and two-dimensional contrast-enhanced ultrasonography (2D-CEUS).MethodsTotally,65 patients with 67 focal liver lesions were examined with 2D-CEUS and dynamic 3D-CEUS.Enhancement patterns,sharpness or three-dimensional effect in different phases,definition of blood vessel in arterial phase and spatial relationships of tumor and vascularity of different hepatic tumors on the two imaging modes were compared statistically,the value of two modes in differential diagnosis of hepatic tumors was also evaluated.ResultsDynamic 3D-CEUS was similar to 2DCEUS with respect to enhancement patterns,sharpness or three-dimensional effect of tumor in arterial and portal phases( P >0.05).And there was no significant difference between the value of dynamic 3D-CEUS and 2D-CEUS in differential diagnosis of hepatic tumors:the sensitivity,specificity,positive predictive value and negative predictive value were 98.0%,81.3 %,94.3 % and 92.9% for 3D-CEUS,and were 96.1%,81.3%,94.2% and 86.7% for 2D-CEUS,respectively.However,3D-CEUS was superior to 2D-CEUS in the display of definition of blood vessel in arterial phase,and spatial relationships of hepatic tumor and vascularity( P <0.05).ConclusionsDynamic 3D-CEUS is a useful technique in the differential diagnosis of hepatic tumors as well as 2D-CEUS,and dynamic 3D-CEUS displays the spatial relationship of hepatic tumors and vascularity more visually and effectively,which provides additional information in the diagnosis and therapy of hepatic tumors.
