A series of poly（aryleneethynylene）s containing dibenzosilole unit has been synthesized by palladium-catalyzed Sonogashira cross-coupling reactions with 2,7-diethynyl-9,9-dihexyl-3,6-dimethoxy-9H-dibenzosilole （4） as the key monomer. Their photophysical properties in solution were investigated. All of the polymers showed intense fluorescence with high quantum efficiencies.

The plane-wave pseudopotential function method, based on density-functional theory, has been used to calculate the adsorption, electronic band structures, orbitals and optical absorption spectrum of [Fe（CN）6]^4- on TiOz anatase（101） surface. Our calculations reveal that the surface-modified anatase system has large adsorption energy and a much narrower band gap. [Fe（CN）6]^4- adsorption on the （101） surface could lead to a large red shift of the anatase optical absorption threshold, which extends into a visible region significantly. The calculated results are in agreement with the experiment and other theoretical studies reasonably. It is very important for the understanding and further development ofphotovoltaic materials that are active under visible light.

Fruiting bodies(500 g per site) of Tricholoma matsutake and the surface layer of soils collected from 20 spatially distant areas with pristine backgrounds across China were analyzed for potassium,magnesium,calcium,zinc,iron,copper,manganese and cadmium using inductively coupled plasma optical emission *** terms of the bioconcentration and bioexclusion concept,K,Mg,Zn,and Cu were highly bioconcentrated,and their bioconcentration factor values varied between 75-615,2-107,38-603 and 7-76,respectively,across the 20 ***,Mn and Cd were moderately bioconcentrated and their bioconcentration factors(BCFs) varied between 0.6-34.0,0.4-37.0 and 0.9-7.0 ***,Ca was excluded(BCF<1).*** is a species that is harvested in the wild as a valuable food and can contain a wide spectrum of both essential and hazardous mineral compounds that accumulate at elevated concentrations even if grown in pristine *** estimated intake rate of Cd in the fruiting bodies indicates cause for concern associated with this metal resulting from the daily consumption of between 200 and 400 g of fruiting bodies on a frequent basis during the mushrooming season.

AIM： To investigate the expression and distribution of HBV in the ovaries and ova. METHODS： The immunohistochemistry method was used to detect the HBsAg and HBcAg in the ovaries of patients with chronic hepatitis B. RESULTS： Expression of HBsAg in the ova, granular and interstitial cells of the ovaries was located in the cytomembrane and cytoplasm. Expression of HBcAg in the ova, granular, interstitial and endothelial cells of interstitial blood vessels of the ovaries was found in the cytomembrane, cytoplasm, and nuclei. CONCLUSION： HBV can infect the ova at different stages of development and replicate in it. 2005 The W3G Press and Elsevier Inc. All rights reserved.

Direct formic acid fuel cells are a promising portable power-generating device, and the development of efficient anodic catalysts is essential for such a fuel cell. In this work Pt-Bi nanoparticles supported on micro-fabri- cated gold wire array substrate were synthesized using an electrochemical deposition method for formic acid oxida- tion in fuel cells. The surface morphology and element components of the Pt-Bi/Au nanoparticles were character- ized, and the catalytic activities of the three Pt-Bi/Au nanoparticle electrodes with different Pt/Bi ratios for formic acid oxidation were evaluated. It was found that Pt4Bi96/Au had a much higher catalytic activity than Pt11Bis89/Au and Pt13Bis87/Au, and Pt4Bi96/Au exhibited a current density of ***^-2, which was 27-times greater than that of Pt/Au. The electro-catalytic activity of the Pt-Bi/Au electrode for formic acid oxidation increased with the increasing Bi content, suggesting that it would be possible to achieve an efficient formic acid oxidation on the low Pt-loading. Therefore, the Pt-Bi/Au electrode offers a promising catalyst with a high activity for direct oxidation of formic acid in fuel cells.

OBJECTIVE Mesenchymal hamartoma of the liver (MHL) is a rare disease that makes up about 5%-8% of primitive hepatic tumors in children. The etiology of MHL has been the subject of considerable discussion. The possibility of malignant transformation of MHL is inclusive. To enhance the recognition of MHL in children, we have review the procedures in diagnosis and treatment and present 4 of our own cases. METHODS The clinical characteristics of MHL in 4 children including history, physical examination, lab examination, imaging data and pathology were analyzed and discussed and related to reports from the literature. RESULTS All the cases were diagnosed with B-ultrasonography and CT preoperatively, and were confirmed intra-operatively and histologically. Satisfactory results were reached postoperatively. CONCLUSION MHL is an uncommon benign lesion in children. The main presentation is abdominal painless mass. Diagnosis is aided with B-ultrasonography and CT preoperatively. Complete tumor removal is the best choice for MHL treatment resulting in a good outcome.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
