Abstract: Coprinus comatus cultivated on cotton seed hull medium decomposed lignocellulose straggly and was high of absolute biological efficiency. Lignocellulose is the main carbon source for the fruiting stage of the fungus. There existed the positive correlation between the degradation rates of the cellulose and hemicellulose in the medium and the activities of extracellular CMCase (carboxymenthelcel lulase), FPase (filter paper cellulase) and HCase (hemicellu-lase), there also existed the positive correlation between the degradation rate of the lignin in the medium and the activity of extracellular laccase, but no correlation between the degradatio rate of the lignin in the medium and the activity of peroxidase. The activity of extracellular amylase was comparatively high at mycelial growth stage, and the protease activity peek was at teh time when the fruitbody matured.

Abstract: 大安国寺由玄宗的父亲睿宗舍宅而立,在开元时期(713—741)汇集了各种学派的僧侣,成为长安最为重要的皇家寺院。俄藏《开元廿九年(741)授戒牒》表明,开元二十九年二月,大安国寺僧人释道建曾经受命来沙州主持授戒仪式,并宣讲唐玄宗刚刚编纂完毕的《御注金刚经》以及《法华经》、《梵网经》。此举为长安佛教与敦煌佛教之间搭建起一座桥梁,通过两地的联系,长安新的佛典、画样、艺文等都传入敦煌,给敦煌佛教文化增添了光彩。这件文书也为我们探讨长安与敦煌的关系问题留下了更多想象的空间。

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0076799
Abstract: Background Antidepressants are effective in treating interferon-α/ribavirin (IFN-α/RBV)-associated depression during or after treatment of chronic hepatitis C (CHC). Whether antidepressant prophylaxis is necessary in this population remains under debate. Methods Comprehensive searches were performed in Medline, Embase, Cochrane Controlled Trials Register and PubMed. Reference lists were searched manually. The methodology was in accordance with the 2009 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) Statement. Results We identified six randomized, double-blind, placebo-controlled trials involving 522 CHC patients treated with pegylated (PEG)-IFN-α plus RBV. The antidepressants used were escitalopram, citalopram, and paroxetine, which are selective serotonin reuptake inhibitors (SSRIs). The rates of depression (17.9% vs. 31.0%, P = 0.0005), and rescue therapy (27.4% vs. 42.7%, P<0.0001) in the SSRI group were significantly lower than those in the placebo group. The rate of sustained virological response (SVR) (56.8% vs. 50.0%, P = 0.60) and drug discontinuation (18.7% vs. 21.1%, P = 0.63) in the SSRI group did not differ significantly to those in the placebo group. In terms of safety, the incidence of muscle and joint pain (40.8% vs. 52.4%, P = 0.03) and respiratory problems (29.3% vs. 40.1%, P = 0.03) were lower, but the incidence of dizziness was significantly higher (22.3% vs. 10.2%, P = 0.001) in the SSRI group. Conclusion Prophylactic SSRI antidepressants can significantly reduce the incidence of PEG-IFN-α/RBV-associated depression in patients with CHC, with good safety and tolerability, without reduction of SVR.

Abstract: P2X purinoceptor 7 (P2X7R), an ATP-gated ion channel, plays an important role during the innate immune response in mammals. However, relatively little is known about the role of P2X7R in the fish immune system. Here, we cloned a cDNA sequence encoding ayu (Plecoglossus altivelis) P2X7R (aP2X7R). The predicted protein was composed of 574 amino acid residues with a P2X family signature, two transmembrane domains, and a long C-terminal. aP2X7R transcripts were mainly distributed in ayu immune tissues and significantly increased in all tested tissues and in macrophages after Listonella anguillarum infection. The aP2X7R protein was upregulated significantly in macrophages upon bacterial challenge. An antibody against the ectodomain of aP2X7R (aEPAb) and an antagonist (oATP) were used to block aP2X7R. aP2X7R siRNA was also used to knockdown the receptor expression in ayu macrophages. Cell death induced by ATP was significantly inhibited in ayu macrophages after aEPAb, oATP, or siRNA treatment. Moreover, aP2X7R ablation also resulted in suppression of phagocytic activity and ATP-induced bacterial killing in ayu macrophages. Our results indicated that aP2X7R was upregulated after infection and mediated cell death, phagocytosis, and bacterial killing of ayu macrophages.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0042826
Abstract: Background and Objectives Studies investigating the association between glutathione S-transferase M1 (GSTM1) gene polymorphism and laryngeal cancer risk have reported conflicting results. The aim of the present study was to conduct a meta-analysis assessing the possible associations of GSTM1 gene polymorphism with laryngeal cancer risk. Methods The relevant studies were identified through a search of PubMed, Embase, ISI Web of Knowledge and Chinese National Knowledge Infrastructure until May 2011 and selected on the basis of the established inclusion criteria for publications, then a meta-analysis was performed to quantitatively summarize association of GSTM1 polymorphism with laryngeal cancer susceptibility. Results Seventeen studies were included in the present meta-analysis (2,180 cases and 2,868 controls). The combined results based on all studies showed that GSTM1 null genotype was associated with increased laryngeal cancer risk (OR = 1.17, 95% CI = 1.04~1.31). When stratifying for race, GSTM1 null genotype exhibited increased laryngeal cancer risk in Caucasians (OR = 1.15, 95% CI = 1.01~1.31), while no significant association was detected in Asians (OR = 1.25, 95% CI = 0.80~1.96). In the subgroup analysis based on source of controls, significant associations were observed in the population-based studies (OR = 1.15, 95% CI = 1.01~1.31) yet not in the hospital-based studies (OR = 1.25, 95% CI = 0.93~1.67). Furthermore, in the subgroup analysis based on sample size, significant associations were also found in studies with at least 50 cases and 50 controls (OR = 1.15, 95% CI = 1.02~1.30) but not in studies with fewer than 50 cases or 50 controls (OR = 1.46, 95% CI = 0.87~2.46). Conclusions This meta-analysis supported that the GSTM1 gene polymorphism was associated with laryngeal cancer, particularly in Caucasians, and these associations varied in different subgroup, which indicated that population-based study with larger sample size was more appropriate in design of future study.

Abstract: This paper presented a kind of circular algorithm,according to principles of concentric circles localization algorithm,based on analyzing several common wireless sensor nodes localization algorithm.The circular localization algorithm focuses on the use of certain rules made by the anchor nodes to drawings in order to continuously reduce the unknown node estimation area is taken until the end to get the smallest region containing the unknown nodes.Then,the centroid position in the smallest area is takero as the estimate coordinates of the unknown nodes.The compared simulation experiments between the concentric circles localization algorithm and circular localization algorithm and the improved schemes show that when the anchor nodes proportion increase to 5%,and in the 20 * 20 square meter simulation scenarios 1000 sensor nodes are deployed and the anchor node density is 5%,the error of concentric circles localization algorithm is 34.86%,and the circular localization algorithm is 26.64%.The improved scheme uses multiple methods of partitioning rings to improve positioning accuracy.The experimental results show that when the anchor node density is 5%,the localization error of the improved algorithm is reduced to 15.76%.

Abstract: In this article, the principles and methods of the dust storm monitoring with multi_channel image from the meteorological satellite are discussed. With the method, the 12 dust storm weather processes that affected a large area in the North China during the period of March to April of year of 2000 were monitored timely. With the analysis of monitoring data, it shows that the dust storm for Beijing region is mainly from the Inner Mongolia Autonomous Region and Hebei Province. They provide a valuable information for the government Department in planning for the dust storm prevention.
