In this paper, we propose a spectral DY-type projection method for nonlinear mono- tone system of equations, which is a reasonable combination of DY conjugate gradient method, the spectral gradient method and the projection technique. Without the differen- tiability assumption on the system of equations, we establish the global convergence of the proposed method, which does not rely on any merit function. Furthermore, this method is derivative-free and so is very suitable to solve large-scale nonlinear monotone systems. The preliminary numerical results show the feasibility and effectiveness of the proposed method.

A novel cathodic–anodic-electrolysis packing（CAEP） used in the treatment of pyridine wastewater was researched, which mainly consisted of 4,4′-diamino-2,2′-disulfonic acid（DSD acid） industrial iron sludge. The physical properties and morphology of the packing were studied. The CAEP was used in a column reactor during the pretreatment of pyridine wastewater. The influence of p H, hydraulic retention time（HRT）, the air–liquid ratio（A/L）and the initial concentration of pyridine were investigated by measuring the removal of total organic carbon（TOC） and pyridine. The characterization results showed that the bulk density, grain density, water absorption percentage and specific surface area were 921 kg/m3,1086 kg/m3, 25% and 29.89 m^2/g, respectively; the removal of TOC and pyridine could reach50% and 58% at the optimal experimental conditions（p H = 3, HRT = 8 hr, A/L = 2）. Notably,the surface of the packing was renewed constantly during the running of the filter, and the handling capacity was stable after running for three months.

Myostatin or GDF-8, a member of the transforming growth factor-β （TGF-β） superfamily, has been demonstrated to be a negative regulator of skeletal muscle mass in mammals. In the present study, we obtained a 5.64 kb sequence of myostatin encoding gene and its promoter from largemouth bass （Micropterus salmoides）. The myostatin encoding gene consisted of three exons （488bp, 371 bp and 1779bp, respectively） and two introns （390bp and 855 bp, respectively）. The intron-exon boundaries were conservative in comparison with those of mammalian myostatin encoding genes, whereas the size of introns was smaller than that of mammals. Sequence analysis of 1.569 kb of the largemouth bass myostatin gene promoter region revealed that it contained two TATA boxes, one CAAT box and nine putative E-boxes. Putative muscle growth response elements for myocyte enhancer factor 2 （MEF2）, serum response factor （SRF）, activator protein 1 （AP1）, etc., and muscle-specific Mt binding site （MTBF） were also detected. Some of the transcription factor binding sites were conserved among five teleost species. This infunnation will be useful for studying the tran- scriptional regulation of myostatin in fish.

Analysis of the effect of changes in fluid properties of rocks on the compressional-wave velocity VP and shear-wave velocity Vs is very important for understanding the rock physical properties, especially in oilfield exploration and development. The fluid substitution process was analyzed by using ultrasonic measurement and theoretical calculations. The results showed that the effect of fluid substitution on the rock elastic modulus was mainly controlled by fluid properties, saturation, and confining pressure. For a rock with specific properties and porosity, the result of theoretical prediction for fluid substitution accorded with the experimental result under high confining pressure （higher than 60 MPa for our experimental data）, but failed to describe the trend of experimental result under low confining pressure and VP predicted by Gassmann＇s equation was higher than that measured by experiment. A higher porosity resulted in stronger sensitivity of the bulk modulus of saturated rocks to the change of fluid properties.

Administration of chicory polysaccharides(CP) can modify lipid metabolism, improve dyslipidemia, and reduce liver inflammation, all of which may help alleviate non-alcoholic fatty liver disease(NAFLD). However, the underlying mechanisms remain unclear. This study aimed to gain further understanding of the potential molecular mechanisms that mediate the protective effects of CP against NAFLD via transcriptomic and metabolomic analyses. Hepatic RNA-sequencing analysis demonstrated that long-term intake of CP restored expression of lipid metabolism-related genes Xbp1, Insig2, and Cth in NAFLD rats, thereby inhibiting de novo lipogenesis. Moreover, CP consumption restored expression levels of genes involved in pro-inflammatory responses, such as Irf1. In addition, metabolic data confirmed that CP treatment increased levels of L-palmitoylcarnitine and hexadecanoyl-Co A, implying that CP administration can promote hepatic fatty acid β-oxidation. The present results demonstrate the underlying mechanisms of CP in high-fat dietinduced NAFLD rats and suggest that CP treatment might provide a dietary therapeutic tool for the treatment of NAFLD in humans.
