The main purpose of this paper is to study the persistence of the general multispecies competition predator-pray system with Holling Ⅲ type functional response. In this system, the competition among predator species and among prey species are simultaneously considered. By using the comparison theory and qualitative analysis, the sufficient conditions for uniform strong persistence are obtained.

The （G＇/G, 1/G）-expansion method for finding exact travelling wave solutions of nonlinear evolution equations, which can be thought of as an extension of the （G＇/G）-expansion method proposed recently, is presented. By using this method abundant travelling wave so- lutions with arbitrary parameters of the Zakharov equations are successfully obtained. When the parameters are replaced by special values, the well-known solitary wave solutions of the equations are rediscovered from the travelling waves.

A novel application of horseradish peroxidase （HRP） in the oxidation of alcohol ethoxylate to alkylether carboxylic acid in the present of H2O2 was reported in this paper. We propose the mechanism for the catalytic oxidation reaction is that the hydrogen transfers from the substrate to the ferryl oxygen to form the α-hydroxy carbon radical intermediate. The reaction offers a new approach for further research structure and catalytic mechanism of HRP and production of alkylether carboxylic acid.

Objective To investigate the effect of H2S on lower limb ischemia-reperfusion （liR） induced lung injury and explore the underlying mechanism. Methods Wistar rats were randomly divided into control group, IR group, IR＋ Sodium Hydrosulphide （NariS） group and IR＋ DL-propargylglycine （PPG） group. IR group as lung injury model induced by liR were given 4 h reperfusion following 4 h ischemia of bilateral hindlimbs with rubber bands. NariS （0.78 mg/kg） as exogenous H2S donor and PPG （60 mg/kg） which can suppress endogenous H2S production were administrated before liR, respectively. The lungs were removed for histologic analysis, the determination of wet-to-dry weight ratios and the measurement of mRNA and protein levels of aquaporin-1 （AQP1）, aquaporin-5 （AQP5） as indexes of water transport abnormality, and mRNA and protein levels of Toll-like receptor 4 （TLR4）, myeloid differentiation primary-response gene 88 （MyD88） and p-NF-KB as indexes of inflammation. Results liR induced lung injury was accompanied with upregulation of TLR4-Myd88-NF-κB pathway and downregulation of AQP1/AQP5. NariS pre-treatment reduced lung injury with increasing AQP1/AQP5 expression and inhibition of TLR4-Myd88-NF-KB pathway, but PPG adjusted *** and TLR4 pathway to the opposite side and exacerbated lung injury. Conclusion Endogenous H2S, TLR4-Myd88-NF-κB pathway and AQP1/AQP5 were involved in liR induced lung injury. Increased H2S would alleviate lung injury and the effect is at least partially depend on the adjustment of TLR4-Myd88-NF-κB pathway and AQP1/AQP5 expression to reduce inflammatory reaction and lessen pulmonary edema.

The method described in this work provides a sensitive and fast technique for investigating the primary structure of peptides with molecular weight up to 3340 amu. Usually, the metastable ion kinetic energy spectra (MIKES) and collisional activated decomposition (CAD) spectra provide complementary information for the FAB mass spectra, the MIKES and CAD spectra generally contain high-mass sequence ions.

To solve soil shortage in reclaiming subsided land of coal mines, the principal chemical properties of artificial soil formed by mixing organic furfural residue and inorganic fly ash were examined. The results indicated that the artificial soil was suitable for agriculture use after irrigation and desalination, the available nutrients in the artificial soil could satisfy the growth demand of plants, and the pH tended to the neutrality.

Ion cyclotron resonance heating experiments using antenna in the high field side(HFS)have been carried out on HT-7 in different target *** a standard-mode conversion heating scheme with dominant electron heating,anomalous ion heating and DD neutron fluxes higher than those estimated from thermal ions were observed in the present experiments with the ion-ion hybrid resonant layer near the center of *** features of ion cyclotron range frequency(ICRF)antenna in HFS and experiments suggest that this is most probably due to the nonlinear 3/2 harmonic deuterium heating by the mode-converted ion Bernstein wave,which could produce a high energy tail on ion energy distribution.
