1中国劳动力市场上工资收入的户籍歧视显示文摘20世纪80年代以来中国城镇劳动力市场上的农民工数量剧增,然而农民工却长期遭受着方方面面的歧视。其中一个突出表现是农民工和城镇职工之间明显的收入差距。但是,收入差距在多大程度上来源于歧视,学者们的观点并不一致。本文以2007年CHIPs(中国居民家庭收入调查)数据为基础,使用4种方法分解农民工和城镇职工的工资差异,考察劳动力市场上的歧视程度,重点突出指数基准问题对分解结果的影响。本文的实证分析结果显示2007年中国劳动力市场上依然存在对农民工明显的工资待遇歧视,农民工和城镇职工工资差异中的36%无法用禀赋差异解释。本文还强调工资收入歧视并不是检验户籍歧视的唯一指标,准确判断户籍歧视需要更广阔的视角。章莉 李实 William A.Darity Jr. Rhonda Vonshay Sharpe 2014管理世界2014,30,11:111
2中国劳动力市场就业机会的户籍歧视及其变化趋势显示文摘文章首先厘清了劳动力市场分割理论与歧视经济学的区别和联系,并将中国劳动力市场上就业机会的户籍不平等现象界定为以农民工平等就业权利受侵害为本质的经济歧视。其次,使用中国家庭收入调查(CHIP)2002年和2007年数据,运用多元logit模型考察了中国劳动力市场上就业机会的户籍歧视状况和变化趋势。实证分析结果显示:(1)与城镇职工相比,农民工在职业获得、行业进入和所有制部门进入三个维度上都遭受了明显的户籍歧视;(2)与2002年相比,2007年就业机会的户籍歧视呈现恶化趋势,显示了经济发展过程中就业机会分配的'负滴漏效应';(3)农民工人力资本的就业机会回报显著低于城镇职工,这对农民工的人力资本投资决策可能会产生负向激励并导致'前市场歧视'的发生。最后,在理论和实证分析的基础上,文章提出了缓解就业机会户籍歧视的相关政策建议。章莉 李实 William A.Darity Jr. Rhonda Vonshay Sharpe 2016财经研究2016,42,1:57
3Dietary and metabolomic determinants of relapse in ulcerative colitis patients: A pilot prospective cohort study显示文摘AIM To identify demographic, clinical, metabolomic, and lifestyle related predictors of relapse in adult ulcerative colitis(UC) patients.METHODS In this prospective pilot study, UC patients in clinical remission were recruited and followed-up at 12 mo to assess a clinical relapse, or not. At baseline information on demographic and clinical parameters was collected. Serum and urine samples were collected for analysis of metabolomic assays using a combined direct infusion/liquid chromatography tandem mass spectrometry and nuclear magnetic resolution spectroscopy. Stool samples were also collected to measure fecal calprotectin(FCP). Dietary assessment was performed using a validated self-administered food frequency questionnaire. RESULTS Twenty patients were included(mean age: 42.7 ± 14.8 years, females: 55%). Seven patients(35%) experienced a clinical relapse during the follow-up period. While 6 patients(66.7%) with normal body weight developed a clinical relapse, 1 UC patient(9.1%) who was overweight/obese relapsed during the follow-up(P = 0.02). At baseline, poultry intake was significantly higher in patients who were still in remission during follow-up(0.9 oz vs 0.2 oz, P = 0.002). Five patients(71.4%) with FCP > 150 μg/g and 2 patients(15.4%) with normal FCP(≤ 150 μg/g) at baseline relapsed during the follow-up(P = 0.02). Interestingly, baseline urinary and serum metabolomic profiling of UC patients with or without clinical relapse within 12 mo showed a significant difference. The most important metabolites that were responsible for this discrimination were trans-aconitate, cystine and acetamide in urine, and 3-hydroxybutyrate, acetoacetate and acetone in serum. CONCLUSION A combination of baseline dietary intake, fecal calprotectin, and metabolomic factors are associated with risk of UC clinical relapse within 12 mo.Ammar Hassanzadeh Keshtel iFloris F van den Brand Karen L Madsen Rupasri Mandal Rosica ValchevaKaren I Kroeker Beomsoo Han Rhonda C Bell Janis Cole Thomas Hoevers David S Wishart Richard N Fedorak Levinus A Dieleman 2017World Journal of Gastroenterology2017,23,21:9

6Intestinal M cells:The fallible sentinels?显示文摘The gastrointestinal tract represents the largest mucosal membrane surface in the human body. The immune system in the gut is the first line of host defense against mucosal microbial pathogens and it plays a crucial role in maintaining mucosal homeostasis. Membranous or microfold cells, commonly referred to as microfold cells, are specialized epithelial cells of the gut-associated lymphoid tissues (GALT) and they play a sentinel role for the intestinal immune system by delivering luminal antigens through the follicle-associated epithelium to the underlying immune cells. M cells sample and uptake antigens at their apical membrane, encase them in vesicles to transport them to the basolateral membrane of M cells, and from there deliver antigens to the nearby lymphocytes. On the flip side, some intestinal pathogens exploit M cells as their portal of entry to invade the host and cause infections. In this article, we briefly review our current knowledge on the morphology, development, and function of M cells, with an emphasis on their dual role in the pathogenesis of gut infection and in the development of host mucosal immunity.Harvey Miller Rhonda KuoLee Girishchandra B Patel 2007World Journal of Gastroenterology2007,13,10:6

9中美环境辐射监测系统比较显示文摘目的旨在通过对中美环境放射性监测系统的比较,以期对各自的发展或类似系统的发展起到一定的参考作用。方法通过对中国国家放射性污染监测系统(NRCMS)和美国环境辐射监测系统(ERAMS)、环境测量研究所(EML)全球放射性监测网在样品采集、放射性核素分析以及数据发布等方面的比较,给出各系统的异同点。结果NRCMS和ERAMS在职责、目的、监测对象等方面有很大的相似性,差异主要存在于监测的规模和大小上。EML全球监测网在地表空气放射性核素监测方面是全球最大、最全面和最有成效的。结论与EML全球监测网相比较,NRCMS和ERAMS存在更大的相似性,差异较小。任天山 Rhonda Sears John Griggs 徐翠华 尚兵 朱昌寿 H.N.Lee Anthony Wolbarst 2007中华放射医学与防护杂志2007,27,1:3
10Siglec genes confer resistance to systemic lupus erythematosus in humans and mice显示文摘A recent meta-analysis revealed the contribution of the SIGLEC6 locus to the risk of developing systemic lupus erythematosus(SLE).However,no specific Siglec(sialic acid-binding immunoglobulin-like lectin)genes(Siglecs)have been implicated in the pathogenesis of SLE.Here,we performed in silico analysis of the function of three major protective alleles in the locus and found that these alleles were expression quantitative trait loci that enhanced expression of the adjacent SIGLEC12 gene.These data suggest that SIGLEC12 may protect against the development of SLE in Asian populations.Consistent with human genetic data,we identified two missense mutations in lupus-prone B6.NZMSle1/Sle2/Sle3(Sle1–3)mice in Siglece,which is the murine Siglec with the greatest homology to human SIGLEC12.Since the mutations resulted in reduced binding of Siglec E to splenic cells,we evaluated whether Siglece−/−mice had SLE phenotypes.We found that Siglece−/−mice showed increased autoantibody production,glomerular immune complex deposition and severe renal pathology reminiscent of human SLE nephropathy.Our data demonstrate that the Siglec genes confer resistance to SLE in mice and humans.Rhonda Flores Peng Zhang Wei Wu Xu Wang Peiying Ye Pan Zheng Yang Liu 2019Cellular & Molecular Immunology2019,16,2:3

12Collision tumor of the kidney composed of clear cell carcinoma and collecting duct carcinoma: report of a case with unusual morphology and clinical follow-up显示文摘We report the case of a 67-year-old female who presented with a large renal mass. Gross examination of the nephrectomy specimen demonstrated a 6-cm renal mass that invaded into the renal sinus and perinephric fat. Histologic examination revealed two distinct tumor types. The first type was a conventional(clear cell) renal cell carcinoma that was of low nuclear grade and comprised the minority of the overall tumor. The second type was a high-grade collecting duct carcinoma with glandular/tubular differentiation and composed the majority of the tumor. Immunohistochemical studies demonstrated distinctive patterns of the two tumor types, thus confirming two distinct lineages. Five months postoperatively, the patient developed metastasis to the lungs and right hilar lymph node region. A fine needle aspiration of a lung nodule demonstrated a metastatic, poorly differentiated carcinoma, similar to the collecting duct carcinoma component in the kidney. Collision tumors of the kidney are rare with fewer than 10 cases reported in the literature. Our report further expands the spectrum of this rare phenomenon.Rhonda Burch-Smith Nizar M Tannir Erika Resetkova Pheroze Tamboli Priya Rao 2014Chinese Journal of Cancer2014,33,7:3

14Gastrointestinal B-cell lymphomas:From understanding B-cell physiology to classification and molecular pathology显示文摘The gut is the most common extranodal site where lymphomas arise. Although all histological lymphoma types may develop in the gut, small and large B-cell lymphomas predominate. The sometimes unexpected finding of a lymphoid lesion in an endoscopic biopsy of the gut may challenge both the clinician (who is not always familiar with lymphoma pathogenesis) and the pathologist (who will often be hampered in his/her diagnostic skill by the limited amount of available tissue). Moreover, the past 2 decades have spawned an avalanche of new data that encompasses both the function of the reactive B-cell as well as the pathogenic pathways that lead to its neoplastic counterpart, the B-cell lymphoma. Therefore, this review aims to offer clinicians an overview of B-cell lymphomas in the gut, and their pertinent molecular features that have led to new insights regarding lymphomagenesis. It addresses the question as how to incorporate all presently available information on normal and neoplastic B-cell differentiation, and how this knowledge can be applied in daily clinical practice (e.g., diagnostic tools, prognostic biomarkers or therapeutic targets) to optimalise the managment of this heterogeneous group of neoplasms.Xavier Sagaert Thomas Tousseyn Rhonda K Yantiss 2012World Journal of Gastrointestinal Oncology2012,4,12:2
