Objective To assess the feasibility of real-time Bi-Plane in observing normal mitral annular areas in different gestational ages.Methods Routine two-dimensional echocardiography and real-time Bi-Plane were used to observe mitral structure and measure the mitral annular area in 159 fetuses.Pearson correlation analysis was used to evaluate the correlation of the areas with gestational age.Visualization rates and acquisition time were recorded and analyzed statistically.Resuits The mitral annular areas measured by two techniques were both correlated to the gestational age (r=0.71,0.75,both P＜0.05).There were significant differences in visualization rate (x2 =4.375,P=0.036) of mitral annular area and acquisition time (t=6.11,P＜0.05) between routine two-dimensional echocardiography and real-time Bi-Plane.Conclusion Real-time Bi-Plane technique is direct,accurate,convenient and fast in observing mitral prenatally.By using Bi-Plane technique to measure mitral annular area,abnormal morphology changes of mitral valve can be evaluated,so as to provide great application value for clinic.

The process of tumorigenesis,local invasion and distant metastasis will produce a series of molecular changes,these genetic mutation or abnormal expression of molecules play a promoting role in hypercoagulation.At the same time,hypercoagulation also increases the risk of tumor progression.It is important to understand their specific processes and the molecular role,and it can provide theoretical basis for better management of patients,and has significance for developing more effective and security new anti-clotting drugs.

The effect of OQP, a pormula of traditional Chinese medieine belonging to the category "Precription of the Reinforeing Qi and Enriching Blood for keep the Original Qi", on cell strain of human hepatic carcinoma SMMC-7721 was observed. The results showed that OQP depressed the incorporation of both ~3H-TdR and ~(14)C-UR in cells of hepatic carcinoma. This indicated that OQP inhibited the synthesis of DNA and RNA, and the growth of the cancer cell. Such effect may result from the low ratio Cu/Zn and the high content of Se in OQP. In conclusion, in this study it has been demonstrated that OQP can not only improve the general condition of patients in advanced liver cancer and lcukopenia of patients in chemotherapy and radiotherapy, but also can inhibite the growth of the cell of hepatic carcinoma directly.

Objective: To investigate the effects of bovine plasma fibronectin on the proliferation and differentiation of rat osteoblasts. Methods:Rat osteoblasts were cultured and identified. AlamarBlue were used to determine the effect of various concentration of bovine plasma fibronectin on the proliferation of the osteoblasts. ELISA method was used to determine the alkaline phosphatase activity of the cells. Results: Fibronectin stimulated the proliferation of rat osteoblasts at 40 ?g/ml (P

Objective To explore the application value of the real-time three-dimensional ultrasound Bi plane technology in evaluation of the foramen ovale blood in fetus.Methods The coronal plane of inferior vena cava entering the right atrium in 186 normal fetuses were obtained.The dimensions of foramen ovale (DFO) and inferior vena cava at the entrance of right atrium (DIVC) were measured in the coronal plane.The ratio of DFO and DIVC (DFO/DIVC) was calculated.The correlation be tween DFO/DIVC and gestational age was analyzed.Results There was no correlation between DFo/DIvc and gestational age (r=0.228,P＞0.05).There were 155 cases during second trimester (21 28 weeks),and the DFO was (4.46±0.57)mm,DIVC was (4.55±1.22)mm,DFO/DIVC was 1.03±0.22.There were 31 cases during late pregnancy (29-36 weeks),and the DFO was (5.20±0.43)mm,DIVC was (5.90±1.33)mm,DFO/DIVC was 0.92±0.17.The mean 95％ confidence interval of DFO/DIVC was (0.98,1.04),the 95％ normal reference range was (0.80,1.44).Conclusion The coronal plane of inferior vena cava entering the right atrium can be obtained with real-time three-dimensional ultrasound Bi-plane technology,the flow from the inferior vena cava enters right atrium which is divided by the upper atrial septum can be observed,which is important in evaluating the foramen ovale blood.

Objective To use the real-time shear wave elastography(SWE)to detect the elasticmodulus values of different breast lesions,and to assess its application value in differential diagnosis of benign and malignant breast lesions.Methods SWE was per-formed in 71 breast lesions from 63 pathologically confirmed patients.The maximum,minimum and mean elasticmodulus values in breast lesions were detected and the ROC curves were used to determine the optimal diagnostic cut off value.Results Among 7 1 le-sions,48 cases were benign lesions and 23 cases were malignant lesions.The diagnostic accuracy and Youden index of the ordinary ultrasound were 77.5% and 0.55 respectively.The maximum,minimum and mean elasticity values for malignant lesions were (106.7±37.9),(23.7±6.4),(44.8±6.6)kPa respectively,whereas which for benign lesions were(42.7±14.6),(17.2±6.3), (29.4±8.0)kPa respectively.The maximum,minimum and mean elastic values had statistically significant differences between be-nign and malignant lesions(P<0.05).The areas under the curve(AUC)of the maximum,minimum and mean elastic values were 0.963,0.798 and 0.914 respectively.Taking 78.1 kPa as the threshold of the maximum elasticity value,the sensitivity was 82.6%and the specificity was 95.8%.Taking 37.6 kPa as the threshold of the mean elasticity value,the sensitivity was 87.0% and the specificity was 83.3%.Conclusion SWE provides a new way for the differential diagnosis of benign and malignant breast lesions, and the maximum and mean elastic value can be used as the diagnostic evidence for differentiating benign and malignant breast le-sions.
