Correlation analysis of gene polymorphisms and β-lactam allergy

A total of 64 patients with β-lactam allergy and 30 control subjects were enrolled in a case-control study. This study is aimed to analyze the relationship between β-lactam allergy and 10 single nucleotide polymorphisms (SNPs) in interleukin-10 (IL-10), IL-13, IL-4Rα, high-affinity immunoglobulin E-receptor β chain (FcεRIβ), interferon γ receptor 2 (IFNGR2), and CYP3A4, and within the Han Chinese population of Northwest China. Genotyping for the SNPs was conducted using the Sequenom MassARRAY®platform. SPSS 17.0 was employed to analyze the statistical data and SHEsis was used to perform the haplotype reconstruction and analyze linkage disequilibrium of SNPs of IL-10 and IL-13. The results showed that the genotype distribution of CYP3A4 rs2242480/CT differed significantly between case and control groups of males (P=0.022; odds ratio (OR)=0.167, 95% confidence interval (CI): 0.032–0.867). Further analysis showed that CCA, CCG, and TAA haplotypes of IL-10 had no significant correlation in patients with β-lactam allergy. The correlation between CCT and CAC haplotypes of IL-13 and β-lactam allergy needs to be further studied. The analysis did not reveal any differences in the distribution of others gene polymorphisms between cases and controls.     

Leaf and root glucosinolate profiles of Chinese cabbage (Brassica rapa ssp. pekinensis) as a systemic response to methyl jasmonate and salicylic acid elicitation

Glucosinolates (GSs) are an important group of defensive phytochemicals mainly found in Brassicaceae. Plant hormones jasmonic acid (JA) and salicylic acid (SA) are major regulators of plant response to pathogen attack. However, there is little information about the interactive effect of both elicitors on inducing GS biosynthesis in Chinese cabbage (Brassica rapa ssp. pekinensis). In this study, we applied different concentrations of methyl jasmonate (MeJA) and/or SA onto the leaf and root of Chinese cabbage to investigate the time-course interactive profiles of GSs. Regardless of the site of the elicitation and the concentrations of the elicitors, the roots accumulated much more GSs and were more sensitive and more rapidly responsive to the elicitors than leaves. Irrespective of the elicitation site, MeJA had a greater inducing and longer lasting effect on GS accumulation than SA. All three components of indole GS (IGS) were detected along with aliphatic and aromatic GSs. However, IGS was a major component of total GSs that accumulated rapidly in both root and leaf tissues in response to MeJA and SA elicitation. Neoglucobrassicin (neoGBC) did not respond to SA but to MeJA in leaf tissue, while it responded to both SA and MeJA in root tissue. Conversion of glucobrassicin (GBC) to neoGBC occurred at a steady rate over 3 d of elicitation. Increased accumulation of 4-methoxy glucobrassicin (4-MGBC) occurred only in the root irrespective of the type of elicitors and the site of elicitation. Thus, accumulation of IGS is a major metabolic hallmark of SA- and MeJA-mediated systemic response systems. SA exerted an antagonistic effect on the MeJA-induced root GSs irrespective of the site of elicitation. However, SA showed synergistic and antagonistic effects on the MeJA-induced leaf GSs when roots and leaves are elicitated for 3 d, respectively.

论英语新闻语篇中显性与隐性评价的动态关系

新闻体裁的客观性、真实性准则决定了新闻话语在不同程度上限制显性评价的呈现,而其中的隐性评价则需要读者通过对描述性话语的正确解读进行合理推断。因此我们将显性、隐性评价与及物结构之间构建联系并探索其中规律,同时结合动态语境进行研究,力图达到对新闻语篇评价色彩整体、准确的把握。     

研发投入、融资约束与出口绿色技术含量

本文基于异质企业的视角,通过修正新古典投资模型分析了企业研发投入、融资约束影响出口绿色技术含量的机理,并构建了企业层面的出口绿色技术含量指标,利用8万多组企业数据对此机理进行验证。得到的结论有:1.企业研发投入对出口绿色技术含量具有显著的正向影响,但私有企业的研发投入的效果要明显好于公有企业、非污染密集型企业的研发投入效果明显好于污染密集型企业。2.融资约束在企业研发影响出口绿色技术含量中具有调节作用,融资约束的这种调节作用在私有控股企业和非污染密集企业中较显著,但该调节作用在公有控股企业和污染密集性企业中不显著。     

出口学习、研发效应与企业生产率提升——来自中国制造业企业的经验证据

基于异质性企业理论的相关国内文献,大多集中在检验中国企业是否存在"出口学习效应",对如何产生"出口学习效应"的具体机理较少涉及。本文认为,产生"出口学习效应"的主要原因来自企业出口后的研发概率与绩效更高,在出口过程中企业会更有可能选择研发投入,且带来的生产率提升更为显著;本文以2004-2007年中国工业企业数据库为样本,基于多达100万个样本点的大数据进行实证检验,结论认为:中国制造业企业出口后选择研发投入的可能性会增加21.63%,而研发投入的选择,给这类企业带来了每年约7.3%的生产率提升。中国企业的出口不仅可以发挥比较优势,解决劳动力就业问题,同时也是为中国制造业企业更加自主选择研发投入,并在中长期提升生产率,获得动态优势的重要途径。
