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.

Objective To study the correlation between prognosis of non-small cell lung cancer ( NSCLC) patient and serum levels of HGF and IL-6. Methods Eligible 109 NSCLC patients and preoperative blood samples of each patient in our hospital from March 2013 to May 2014 were collected. Then the levels of HGF and IL-6 of serum samples were detected by using ELISA kit. All patients were followed up for 1 year. The neoplasm staging:67 cases were stagingⅠ-Ⅱ,38 cases were stagingⅢ,2 cases were staging IV. There were 79 cases with ad-enomatous carcinoma( ADC) ,26 cases with squamous carcinoma( SCC) and 4 cases with NSCLC. According to the TNM staging,there were 79 cases in pN( -) group,31 in pN( +) group,77 in pT(T1-T2) group and 28 in pT(T3-T4) group. Results The average concentration of HGF and IL-6 in serum were 860 pg/mL and 2. 7 pg/mL respectively. Analysis of survival indicated that,compared to those patient with lower serum level of HGF and IL-6,the survival rate of patient with high serum level was much lower. The difference was statistically signifi-cant (HGF,P=0. 019;IL-6,P=0. 002). The analysis of the patients with stageⅢdisease separately also indicated that survival rate of pa-tient with lower serum of HGF and IL-6 was higher than others. Conclusion The serum levels of HGF and IL-6 might be a effective indica-tors for predicting prognosis of the NSCLC paitents.

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.

Chorismic acid is a mid-metabolite that plays a central role in the metablism process distributing in the bacterium, epiphyte and plants. It is a common precursor substance of the all aromatic amino acids that can turn into phenylalanine and tyrosine catalyzed by bi-functional enzyme chorismate mutase (CM)-prephenate dehydratase (PDT) and chorismate mutase-prephenate dehydrogenase (PDH) respectively. CMp-PDT with its regulate domain Rp were called P-protein and CMt-PDH with its regulate domain Rt were called T-protein. P-protein and T-protein from E. coli. have a similar structure, both of which contained three domains: CMp, PDT, Rp in P-protein and CMt, PDH, Rt in T-protein. P-protein and T-protein are regulated by their effectors phenylalanine and tyrosine respectively through binding to their Rp and Rt domains. Rp and Rt domains were switched between P-protein and T-protein by cloning of chimeric proteins. The results showed that regulatory effects were switched along the switch of R domains and the switch of the regulatory domains lead to the switch of effectors. It means that the combination of the regulatory domain and the effector is specific and the regulating of the regulatory domain to the enzyme activity is non-specific. This property of R domains may make them possible molecular elements in the study of molecular machines.
