Ultra fine silicon quantum wires with the Si/SiO2 heterointerface have been fabricated successfully by using reactive ion etching, anisotropic wet chemical etching and subsequent thermal oxidation. The cross-sectional image of scanning electron microscope shows the silicon quantum wires of high quality with the linewidth down to 20nm. The present method has many remarkable advantages, which is important to the study of low-dimension quantum physics and devices.

THE procedure of inertial confinement fusion (ICF) takes place in sub-nanosecond period. Inorder to investigate the hydrodynamic instability and asymmetry during the implosion, weneed to measure the two-dimensional distribution of plasmas temperature and density as well asits relationship with time. For this purpose, an X-ray picosecond multiframe technique hasbeen developed.

The human aspartyl beta-hydroxylase is a highly conserved enzyme that hydroxylates epidermal growth factorlike domains in transformation-associated proteins. The aspartyl beta-hydroxylase gene is upregulated in many human malignancies. The purpose of this study was to investigate the expression of aspartyl beta-hydroxylase in hepatocellular carcinoma. Aspartyl beta-hydroxylase mRNA levels were measured in 161 hepatocellular carcinomas and paired nontumorous liver tissues by conventional and real-time RT-PCR. Immunohistochemical staining of aspartyl beta-hydroxylase was performed using EnVision Plus system. The results showed that aspartyl beta-hydroxylase was overexpressed in 150 of 161 hepatocellular carcinomas (93 %), including 45 of 48 unifocal small hepatocellular carcinomas (94 % ). Aspartyl beta-hydroxylase was highly expressed in hepatocellular carcinoma cells in contrast to its low level of expression in non-neoplastic liver cells. The protein expression level of aspartyl heta-hydroxylase in the hepatocellular carcinoma was parallel with the mRNA expression level (r=0. 659 4, P< 0. 000 1). A significantly higher tumor aspartyl beta-hydroxylase overexpression level was associated with the presence of intrahepatic metastasis and the progression of histological grades.
