An important factor in the emergence and progre sion of osteosarcoma(OS)is the dysregulated expression of microRNAs(miRNAs).Transcription factor 7-like 1(TCF7LI),a member of the T cell factor/lymphoid enhancer factor(TCF/LEF)transcription factor family,interacts with the Wnt signaling pathway regulator β-catenin and acts as a DNA-specific binding *** study sought to elucidate the impact of the interaction between miR 3293p and TCF7L1 *** growth and apoptosis of OS and analyze the regulatory expression relationship between miRNA and mRNA in osteosarcoma cells using a variety of ***329-3p was significantly downregulated,while TCF7L1 was considerably up-regulated in all examined OS cell ***,a clinical comparison study was performed using the TCGA ***,the regulatory relationship between miR-329-3p and TCF7L1 on the proliferation and apoptosis of OS cells was verified through in vitro and in vivo *** miR 329-3p was transfected into the OS cell line,the expression of TCF7L1 decreased,the proliferation of OS cells was inhibited,the cytoskeleton disintegrated,and the nucleus condensed to fom apoptotic *** expression of proteins that indicate apoptosis increased *** cell cycle was arrested in the G0/G1 phase,and the G1/S transition was *** introduction of miR 3293p also inhibited downstream Cyclin D1 of the Wnt *** experiments indicated that the overexpression of miR-329-3p signi ficanly inhibited the growth of OS xenografts in nude mice,and the expression of TCF7L1 and C-Myc in tumor tssues *** 329-3p was significantly reduced in OS cells and played a suppressive role in tumorigenesis and proliferation by targeting TCF7L1 both in vitro and in *** cell cycle arrest and pathway inhibition were observed upon the regulation of TCF7LI by miR *** these results,it can be inferred that miR.3293p exerts anticancer efects in osteosarcom

The fundamental characteristics and the flow mechanism of a Vibrating Flow Pump （VFP） with a jelly-fish valve, which can be applied to a novel artificial heart, were studied theoretically and experimentally. By using water as the working fluid, the measurement methodology for the typical unsteady flow for VFP was developed here. The effects of the frequency, amplitude and inner diameter of the vibrating pipe, and thickness of the silicone rubber sheet of the jelly-fish valve on the basic per- formance of VFP were systematically investigated. A high-speed observation technique and simple theoretical model analysis were also introdueed for further detailed discussion. Quantitative contributions of the individual parameters to the pumping performance were shown through the experiment, which would give us essential knowledge for establishing design criteria of VFE The theoretical model, which agreed with the experiment and the high-speed observation, elucidated the pumping mechanism with respect to the role of inertia of the inner fluid.

To the Editor： Helicohacter pylori （H. pylori） infection plays an important role in the pathogenesis of chronic gastritis and gastric adenocarcinoma Therefore, the accurate diagnosis of H. pylori infection is important. During esopbagogastroduodenoscopy （EGD）, the diagnostic tests for H. pylori infection available are the rapid urease test （RUT）, immunohistopathological examination, and culture. As all of these require gastric mucosal biopsy during EGD.

Japanese lunar explorer SELENE (KAGUyA) was equipped with 14 instruments for various measurements of the Moon. Three of these instruments took geodetic measurements of the Moon. These were two sub-satellites and a laser altimeter. The main results obtained by the instruments are: (1) precise orbit determination with an accuracy of ten meters by Doppler and same-beam VLBI; (2) the first precise gravity fields on the lunar far side by 4-way Doppler measurements; (3) the first topography in latitudes higher than 86 degrees; (4) a global map of the gravity anomaly by using the global topography and the global gravity fields; (5) a global map of the lunar crustal thickness and (6) an illumination rate map in the north and south polar regions.
