To develop a new type of non-oxidant electron acceptors for water oxidation, 3-（methyl）phenyl-（3,5- dimethyl-1H-pyrrol-2-yl）methanone modified silica（SiO2@py） was synthesized and used as host to Co4O4 cubane forming nanoparticles（SiO2@pyCo4）. In the presence of Ru（bpy）3^2＋ and under the irradiation of white LED（light emitting diode） light（10 W）, SiO2@pyCo4 can catalyze water oxidation without extra electron acceptor（e.g., Na2S2O8） Moreover, the turnover frequency（TOF） value of SiO2@pyCo4 is larger than that of Co4O4 cubane under the same conditions, and the longer lasting time of SiO2@pyCo4 indicates that SiO2@py can enhance the stability of Co4O4 in water. Our results provide an economic route to develop dioxygen evolution systems based on the assembly of organic electron acceptor modified silica with active cobalt complexes.

In distributed parallel server system, location and redundancy of repficas have great influence on availability and efficiency of the system. In order to improve availability and efficiency of the system, two phase decision algorithm of replica allocation is proposed. The algorithm which makes use of auto-regression model dynamically predicts the future count of READ and WRITE operation, and then determines location and redundancy of replicas by considering availability, CPU and bands of the network. The algorithm can not only ensure the requirement of availability, but also reduce the system resources consumed by all the operations in a great scale. Analysis and test show that communication complexity and time complexity of the algorithm satisfy O（n）, resource optimizing scale increases with the increase of READ count.

The novel cyclic trithiocarbonate was synthesized by dialkylation of trithiocarbonate anion with 2,2＇- bis（bromomethyl）biphenyl in a two-phase system using an onium salt as a phase-transfer agent. Styrene polymerization was carried out in the presence of cyclic trithiocarbonate （CTTC）. CTTC undergoes ring opening-polymerization and the incorporated trithiocarbonate moiety derived from CTTC performs as the reversible addition-fragmentation chain transfer （RAFT） agent. Through this mechanism, multiblock polys-tyrenes containing various narrow polydispersity blocks can be prepared.

Through-hole structural humidity sensor was fabricated by radio-frequency magnetron sputtering deposition of gold electrodes on two sides of anodic aluminum oxide (AAO) membranes which were prepared by two-step anodization procedure at 0―5℃ and 40 V in 0.5 mol/L oxalic acid electrolyte. The investigation on the impedance at various humid conditions showed a linear relationship between im- pedance and relative humidity over the range of 12%―97% RH. Other excellent properties such as rapid response and good reproducibility were also obtained.

THE incidence of isolated right heart infective endocarditis （IE） is far less common than that of left heart. Clinical presentation is often associated with pulmonary manifestations. The main symptoms include high fever, chest pain, and dyspnea due to septic pulmonary emboli. Degenerative valvular disease, congenital heart diseases, prosthetic valves, long-term hemodialysis, diabetes mellitus predispose patients at increased risk of IE.1 In young persons, IE may be associated with intravenous drug abuse.2 This report dealt with a young patient who had none of the risk factors mentioned above. He was diagnosed and treated for lung abscess and septemia for one and a half months. Further investigation unveiled infective vegetation on tricuspid valve. Following surgical resection of the vegetation, fever and respiratory symptoms completely remitted. The mechanism of the IE occurred on the normal native tricuspid valve is proposed.

The fatigue properties of the newly developed wheel steel used for commercial vehicles were studied using push-pull axial loading fatigue tests with stress ratio R=-1. Q235B steel, which is conventionally applied to commercial vehicle wheels, was also analyzed for comparison. Although the chemical composition and microstructure （ferrite and pearlite） of newly developed wheel steel were similar to those of Q235B, the 107 cycles fatigue limit of the new wheel steel was 260 MPa, which is 24% higher than that of Q235B （210 MPa）. The improvement of the fatigue strength of the new wheel steel can be attributed to grain refinement. In order to investigate the effect of the decrease in thickness of the wheel steel on the fatigue property of the wheel, dynamic cornering fatigue tests were conducted on full scale wheels with the model of 8.25 × 22.5. The results indicated that the newly developed wheel steel had outstanding fatigue life even if the mass loss was 10% in comparison with Q235B.

To assess the effects ofcreatine pyruvate （Cr-Pyr） on lipid and protein metabolism in broiler chickens, a total of 400 1-day-old male birds （Aconred） were randomly allocated to four groups, with each group replicating four times and each replicate involving 25 birds. The broilers were provided with a commercial diet supplemented with Cr-Pyr at 0, 1, 5, or 10% of the diet, respectively, for a period of 3 wk ad libitum （from 22 to 42 d）. In the present study, body weight （BW） and average daily gain （ADG） of broilers decreased in 10% Cr-Pyr group （P〈0.01）, whereas the relative leg and pectoral muscle weights were significantly higher than they were in the control group （P〈0.05）. 5 or 10% Cr-Pyr of diets decreased the abdominal fat rate （AFR, abdominal fat/live weight） of the broilers. The serum or hepatic triglyceride （TG） concentrations were significantly lower in the 5 and 10% groups （P〈0.01）. In contrast, Cr-Pyr caused a marked increase in the serum nonesterified fatty acid （NEFA）, high-density lipoprotein cholesterol （HDL-C） and creatine kinase （CK） concentrations （P〈0.01）. Supplementation with Cr-Pyr （5 and 10%） in the diet also increased glucagons （GLU）, insulin （INS） or leptin （LEP） contents （P〈0.01）. The expression of hepatic peroxisomal proliferators-activated receptor α （PPAR-α） and carnitine palmitoyl transferase-I （CPT-I）, muscle insulin-like growth factor I （IGF-I） were significantly elevated and myostatin mRNA level was reduced in the 5 and 10% groups （P〈0.05）. It was found that supplementation with 5% Cr-Pyr improves both lipid and protein metabolism by regulating various metabolic parameters of broilers, while not adversely affects growth performance in broiler chickens.

Objective： To explore the scientific connotation of the discrepant pharmaceutical activities between the head and tail of Angelica sinensis diels（AS）, an important herb extensively utilized in Chinese medicine, by the approach of transcriptome sequencing. Methods： Ten samples of AS were randomly collected in Min County, Gansu Province of China. Transcriptome sequencing of AS was accomplished in a commercial ILLumina Hi Seq-2000 platform. The transcriptome of each head and tail of AS were fixed in a gene chip, and detected under the procedure of Illumina Hi Seq-2000. Differentially expressed unigenes between the heads and tails of AS were selected by Shanghai Biotechnology Corporation（SBC） online analysis system, based on Gene Ontology, Kyoto Encyclopedia of Genes and Genomes and relevant bioinformatic database. Results： Totally 63,585 unigenes were obtained from AS by high-throughput sequencing platform. Among which 3359 unigenes were identified as differentially expressed unigenes between the heads and tails of AS by SBC analysis system scanning. Of which 15 differentially expressed unigenes participate in the metabolic regulation of phenylpropanoid biosynthesis（PB） pathway and ferulic acid metabolites, in response to the distinguished pharmaceutical actions of the heads and tails of AS. Conclusion： Different content of ferulic acid in the heads and tails of AS is related to the differentially expressed genes, particularly involved in the PB pathway.
