Objective To investigate the value of transvaginal contrast-enhanced ultrasonography (CEUS)in the diagnosis of adnexal masses.Methods Thirty patients with adnexal mass were examined by conventional 2D imaging and contrast tuned imaging(CnTI)technology.The results were compared with pathological results and the CEUS features wet concluded.Results There were 21 cases of benign adnexal masses and 9 cases of ovarian malignancies among 30 patients.The CnTI technology can distinguish between solid and cystic parts in masses.CEUS showed that malignant tumor had the high microvessel density and these vessels were irregular in shape.Partial malignant masses had the characteristic in-out phases in CnTI imagine.Conclusions Transvaginal CEUS is benefit to improve the accuracy of diagnosis of pelvic adnexal masses.

Objective To explore the Csx/Nkx 2.5 gene expression in the heart during the embryonic period and its mutation in subjects with congenital heart disease(CHD). Methods Immunohistochemistry was used to reveal the Csx/Nkx 2.5 gene expression, and PCR-SSCP-silver staining and DNA sequencing for mutation. Sixty-three embryos or fetus, 126 children with congenital heart diseases and 30 normal controls were included in the study. Results Elevated expression of Csx/Nkx 2.5 gene was found in atrium and trabecular of ventricle. After 16 weeks of gestation, the expression in atrium was stable, while slightly reduced in the trabecular. The expression in the ventricle was lower than that in the atrium in early embryonic stage followed by continuous increase which was most remarkable in 13~16 weeks and kept stable after 16 weeks. No expression of Csx/Nkx 2.5 was detected in epicardium. Three different kinds of gene polymorphisms in the third base of the 21st amino acid codon were found in all subjects:A,G,A/G. Conclusions Gene Csx/Nkx 2.5 plays an important role during the fetal heart development and its expression varies in different parts of the heart during different period in fetal development. Neither the sporadic nor the CHD cases showed any mutations in this study.

PurposeTo evaluate and describe fetal cardiac development and hemodynamics high risk pregnancy by using ultrasound technique. Methods Two-hundred and thirty-three pregnancies were prospectively studied by using the detailed fetal echocardiographic procedure( fetus gestational age from 19 weeks to 39 weeks). Cardiac chamber size, internal diameter of great arteries were documented together with the presence of inflow and outflow wave patterns. In utero diagnoses of variety of congenital heart defects were also conducted. ResultsCardiac chamber size and internal diameter of great arteries showed a positive correlation with the increasing of gestational age. Left and right ventricles were demonstrated the same size during whole fetal observational period. Blood flow through mitral valve and tricuspid valve were typically 'M' type. By comparing 'e' wave and 'a' wave, this inflow blood velocity pattern was dominant by 'a' wave, though the ratio of a/e gradually decreased during the fetal development period. Blood velocity in aorta and pulmonary artery remained steady along with the gestational age. The detection rate of verity types of congenital heart diseases in this sample population was 5.7% (13 cases) ,the major problem was the complex heart malformation. The occurrence of fetal cardiac arrhythmia was 14 cases (16 % ), with the majority of atrial premature beat. Conclusions Fetal echocardiography can be used to evaluate and monitor the change of cardiac anatomy, structure and hemodymanics during the different gestational age. This has provided a new approach to the further understanding of fetal cardiac development, and is importantto the screening of congenital heart disease during pregnancy.

Objective To screen the optimized Buyang Huanwu Decoction (BYHWD);To verify it. Methods H2O2 was used to induce PC12 cell oxidative stress models. MTT method was used to determine the prevention effects of BYHWD at different concentrations (0.1, 0.2, 0.5, 1.0, 2.0, 3.5 mg/mL) on in vitro oxidative stress cell models to define the optimized concentration. Orthogonal design was used to divide BYHWD single medicine into decomposed BYHWD groups, control group (only with DMEM), normal group (without H2O2 and medicine processing), and model group, to investigate the protective effects on PC12 cells. Optimized BYHWD was screened to decide the compatibility ratio of each medicine. MTT was used to detect the cell survival rate in each group. Middle cerebral artery occlusion was used to replicate MACO rat models. SD rats were randomly divided into sham-operation group, model group, BYHWD group and optimized BYHWD high-, medium-and low-dose groups. Each medication group was given relevant medicine for gavage. The screened results were verified. Results Compared with other decomposed BYHWD groups, the protective effects of the compatibility of Astragali Radix+Chuanxiong Rhizoma+Pheretima on PC12 cells was the best (P<0.05), which was nearly equaled to BYHWD. Compared with the model group, BYHWD and the optimized one could evidently reduce cerebral cortex infarction area and improve the impaired brain edema (P<0.05), and the medium-dose group was the best. Conclusion The optimized BYHWD ratio is:Astragali Radix:Chuanxiong Rhizoma:Pheretima=10:3:1.

Objective To study the expressions of erythmpoietin(EPO)and its receptors(EPOR)in the injured brain tissue ofthe rats with traumatic brain injury(TBI).Methods A total of78 SD rats were randomly divided into three groups including control group(six rats),sham group(36rats) and fluid percussion injury group(36 rats).The rats were sacrificed at 6,24 hours,3,5,7 and 14days after TBI in the sham group and the fluid percussion injury group(six rats at each time point).Then,the injured brain tissues were removed for observation of the mRNA and protein expressions of EPO and EPOR by meaDiB of real-time PCR and Western blot. Results The expression of EPO was increased at 24 hours and reached the peak at day 3 after TBI.The hish expression level of EPO could maintain for two days or so.began to decrease at day 7 and recovered to normal at day 14 after Till.While the expression of EPOR reached the peak at 24 hours after TBI and maintained hish level at day14. Conclusions The expressions of EPO and EPOR show increase within 24 hours after TBI.In fact,the expressions of both factors are not in consistency,with more transient expression of EPO.

Objective To observe the effects of hyperoxia on Notch 1 receptor of alveolar epithelial type Ⅱ cells (AEC Ⅱ), in a hetcrocellular culture of alveolar epithelial type Ⅱ cells and lung flbroblasts(LF), in order to explore Notch signaling in hyperoxic induced lung injury and thus make theoretical basis for prevention and treatment of a acute/chronie neonatal lung injury. Method Twelve Spragne Dawkey female rats with 200～220 g and 3 Spragne Dawkey male rats with 220～250 g were offered from experimental animal centre of Tongji Medical Colleege, Huazhong University of Science and Technology. The AEC Ⅱ/ LF co-culture system was established successfully. AEC H s from premature rats were randomly assigned to 2 groups: air control group and hyperoxia group. Air control group was kept in room air 50% ml/L CO2 enviromnent at 37°C, while hyperoxia group was exposed to 950 ml/L O2 + 250 ml/L CO2. Immuno-histochemistry was taken to detect Notch 1. Fluorescent quantitafive PCR was used to quantify the Notch 1 mRNA. MTT method was taken to assess cen proliferation viability.Flow eytometry double label method was used to detect cell percentages. Results In hyperoxia group:Notch 1 activation was inhibited, and Notch 1 mRNA decreased to 0.43,0.29,0.11,0.03 fold of control (95% confidence limit). AEC Ⅱ percentage descended predominantly[ 24 h hyperoxia group vs. control group: (68.92±6.88)%vs. (90.35±4.01)%, P =0.006;48 h hyperoxia group vs. control group: (38.03±3.27) vs. (61.47±4.81)%, P =0.000;72 h hyperoxia group vs. control group:(20.13±4.45)% vs. (52.05±3.35)%, P =0.000;96 h hyperoxia group vs. control group:(8.17±1.99)% vs. (52.59±2.93)%, P =0.0001 while that d AECI rised[24 h hyperoxia group vs. contrd group:(0.11±0.03)% vs. (0.01±0.01)%, P=0.006;48h hyperoxia group vs. control gnmp:(49.73±3.45)% vs. (16.13±2.13)%, P =0.000;72 h hyperoxia group vs. control group: (52.43±3.14) % vs. (5.98±0.95) %, P = 0.000;96h hyperorxia group vs. control group:(19.85±3.26)% vs. (29.03±3.16)%, P =0.007]. Comclusions Hyperoxia may inhibit Notch signaling pathway, which can weaken proliferation and disdifferentiation of AEC Ⅱ s. Investigations on how to control Notch signaling will provide fresh thoughts for alveolar epithelium repairing.
