There have been reports of potential health risks for people from hydrophobic organic pollutants,such as polycyclic aromatic hydrocarbons(PAHs),polychlorinated hydrocarbons(PCHs),and organophosphate flame retardants(OPFRs).When a contaminated site is used for residential housing or public utility and recreation areas,the soil-bound organic pollutantsmight pose a threat to human *** this study,we investigated the contamination profiles and potential risks to human health of 15 PAHs,6 PCHs,and 12 OPFRs in soils from four contaminated sites in *** used an in vitro method to determine the oral bioaccessibility of soil *** PAHswere found at concentrations ranging from26.4 ng/g to 987 ng/***(0.27-14.3 ng/g)and OPFRs(6.30-310 ng/g)were detected,but at low levels compared to earlier *** levels of PAHs,PCHs,and OPFRs released from contaminated soils into simulated gastrointestinal fluids ranged from 1.74%to 91.0%,2.51%to 39.6%,and 1.37%to 96.9%,*** on both spiked and unspiked samples,we found that the oral bioaccessibility of pollutantswas correlated with their logKow andmolecularweight,and the total organic carbon content and pH of *** in 13 out of 38 contaminated soil samples posed potential high risks to *** considering oral bioaccessibility,nine soils still posed potential risks,while the risks in the remaining soils became *** contribution of this paper is that it corrects the health risk of soil-bound organic pollutants by detecting bioaccessibility in actual soils from different contaminated sites.

Background： Neuromyelitis optica （NMO） and multiple sclerosis （MS） are demyelinating disorders of the central nervous system. Interferon regulatory factor 5 （IRF5） is a common susceptibility gene to different autoimmune disorders. However, the association of IRF5 variants with NMO and MS patients has not been well studied. Therefore, we aimed to evaluate whether IRF5 variants were associated with NMO and MS in the Southeastenl Han Chinese population. Methods： Four single nucleotide polymorphisnls （SNPs） were selected and genotyped by matrix-assisted laser desorption/ionization time of flight mass spectrometry in 111 NMO patients, 145 MS patients and 300 controls from Southeastern China. Results： None of these 4 SNPs was associated with NMO or MS patients. Conclusions： Our preliminary study indicates that genetic variants in IRI~ may affect neither NMO nor MS in the Southeastern Han Chinese population. Further studies with a large sample size and diverse ancestry populations are needed to clarify this isstie.

Background： Neuromyelitis optica （NMO） and multiple sclerosis （MS） are autoimmune demyelinating diseases of the central nerve system, lnterleukin-7 （IL-7） and interleukin-7 receptor alpha （IL-7Rα） were proved to be important in the pathogenesis of both diseases because of the roles they played in the differentiations of autoimmune lymphocytes. The variants of both genes had been identified to be associated with MS susceptibility in Caucasian, Japanese and Korean populations. However, the association of these variants with NMO and MS has not been well studied in Chinese Southeastern Han population. Here, we aimed to evaluate the association of six IL-7 variants （rsl520333, rs1545298, rs4739140, rs6993386, rs7816065, and rs2887502） and one variant of IL-7RA （rs6897932） with NMO and MS among Chinese Han population in southeastern China. Methods： Matrix-assisted laser desorption/ionization time of flight mass spectrometry （MassARRAY system） and Sanger sequencing were used to determine the variants of IL-7 and IL-7RA in 167 NMO patients, 159 MS patients and 479 healthy controls among Chinese Han population in southeastern China. Samples were excluded if the genotyping success rate 〈90%. Results： Statistical differences were observed in the genotypes of IL-7 rs1520333 in MS patients and IL-7RA rs6897932 in NMO patients, compared with healthy controls （P = 0.035 and 0.034, respectively）. There was a statistically significant difference in the genotypes of IL-7 rs2887502 between MS and NMO patients （P = 0.014）. And there were statistically significant differences in the rs6897932 genotypes （P = 0.004） and alleles （P = 0.042） between NMO-IgG positive patients and healthy controls. Conclusions： The study suggested that among Chinese Hart population in southeastern China, the variant of IL-7RA （rs6897932） was associated with NMO especially NMO-IgG positive patients while the variant of IL-7 （rs1520333） with MS patients. And the genotypic differences of IL-7 rs2887502 between M

To the Editor:With the popularity of liver transplantation(LT)and the inspiration for long-time survival,issues related to evaluating the liver allograft have increased in recent years[1-3].Although there has been renewed interest in non-invasive methods to evaluate diffuse liver disease,liver biopsy is still the golden standard in clinical practice,particularly for liver transplant recipients(LTRs).The liver biopsy has always been performed in LTRs as a part of standard procedure in cases whose liver function was normal,named as protocol liver biopsy,or to identify histological abnormalities for abnormal liver function and provide guidance for the adjustment of immunosuppressive regimen[4,5].Percutaneous liver biopsy(PLB)has been frequently conducted in LTRs;however,the clinical implementation of protocol liver biopsy by PLB in LTRs is challenging due to their suboptimal compliance,particularly in China[6].Besides,the PLB procedure has been associated with discomfort and potentially life-threatening complications in the general population,as reported in the literature[7,8].

本文以沪深两市A股制造业上市公司为研究对象,基于2012-2014年的面板数据,运用STATA 12探讨企业社会责任对应计和真实盈余管理的不同影响。对于企业社会责任的衡量,本文运用因子分析法构建了我国制造业企业社会责任评价体系,将科技创新、质量安全等纳入评价体系中,将各企业的综合得分作为社会责任的衡量指标;对于应计盈余管理的计量,本文运用修正的琼斯模型;对于真实盈余管理的计量,本文借鉴Roychowdhury的做法将异常的产品成本、经营活动净流量、酌量性费用三部分的综合指标作为真实活动盈余管理的衡量指标。研究结果发现:制造业上市公司会同时进行应计和真实盈余管理两种方式,且企业社会责任与应计盈余管理、真实盈余管理均呈显著的负相关关系,这表明企业履行社会责任是一种道德行为,履行社会责任好的企业,其信息披露更加透明,从而抑制盈余管理行为。此研究结果进一步丰富了企业社会责任与盈余管理的相关研究,对制造业的监管提供了指导性建议。

世界观不是指关于世界的根本看法或观点，而是指在关于世界的根本看法或观点基础上自发形成或自觉构建的关于世界总体的根本性总体性观念。世界观存在着真理性问题，只有那种与其对象相一致并且对自己和他者有利的世界观才是真理性世界观，也是正确的世界观。从历史演进的角度看，历史上有影响的世界观主要包括为所有人信奉的常识世界观、为宗教组织内信徒信奉的宗教世界观、为大多数人信奉的科学世界观和为部分人信奉的哲学世界观四大类型。就人们可选择的世界观而言，宗教世界观是完全不正确的世界观，科学世界观是不完全正确的世界观，只有哲学本体论才能提供正确的世界观。但哲学世界观的正确性仍然存在着很大的差异，哲学家的使命在于为人们提供具有真理性的本体论所支撑的真正正确的世界观。
