高通量抗体芯片研究AILD血清炎性因子表达特征   总被引:1,自引:0,他引:1  
利用微阵列抗体芯片技术检测53例自身免疫性肝病(AILD)患者血清中20种辅助性T细胞相关炎性因子的表达水平,结合肝功能临床生化数据,分析炎性因子的表达特征和差异性.高通量抗体芯片检测结果显示:AIH-PBC OS患者血清中IL-4和TGFβ1表达量水平显著高于PBC组(P0.05),AIH-PBC OS患者血清中IL-4表达量水平显著高于健康对照组(P0.05),PBC患者血清中IL-4和TGFβ1表达量水平显著低于健康对照组(P0.05).PBC患者血清中TGFβ1表达量与ALT(r=-0.6301,P=0.0135)、AST(r=-0.7443,P=0.0030)呈显著负相关.结果表明:IL-4和TGFβ1在AIH-PBC OS患者和PBC患者血清中表达量差异(P0.05)和TGFβ1表达量与AILD患者肝功能指标间的相关性为筛选具有临床检验、诊断、治疗和预后监测意义的AILD相关细胞因子奠定了基础.  相似文献

风湿性疾病的发生多与自身免疫异常有关,所以风湿病的一大特征是患者血液中自身抗体的出现。自身抗体是易感者(易感基因)在环境因素(病毒等)诱导下对自身组织或成分的异常免疫反应,见于多种风湿性疾病,尤其在弥漫性结缔组织病中更为常见。自身抗体检测被广泛用于疾病早期诊断和分类弥漫性结缔组织病、疾病机理研究、提示疾病活动性、预后及预防。  相似文献

<正>自身免疫性肝炎(AIH)是一种重症的、进展性肝病,多见于女性,常伴有遗传因素(HLAB_8和DR_3)、高丙种球蛋白血症和组织自身抗体存在.临床特点是门脉周围(汇管区)碎屑样坏死伴明显浆细胞浸润.大多数患者对免疫抑制剂敏感,病因目前尚不清楚,据推测嗜肝病毒感染可能导致本病,但是自身免疫性肝炎伴HBV感染的病例是很少见的.  相似文献

目的探讨妊娠期母体自身免疫性甲状腺疾病(AITD)患者检测血清促甲状腺激素(TSH)、血清游离三碘甲状原氨酸(FT3)、血清游离甲状腺素(FT4)、甲状腺球蛋白抗体(TGAb)、甲状腺过氧化物酶抗体(TPOAb)、血清促甲状腺素受体抗体(TRAb)、IL-17(白细胞介素17)的意义.方法应用化学发光免疫分析法(CLIA)检测妊娠早、晚期4组孕妇血清TSH,FT3,FT4,TGAb,TPOAb,TRAb等甲状腺疾病相关指标,同时用酶联免疫吸附试验(ELISA)检测受试者IL-17的水平.结果入组的4组AITD患者TSH,FT3,FT4水平表现出差异性变化,不同诊断的患者甲状腺功能指标均有显著差别. AITD患者的甲状腺自身抗体TCAb、TPOAb、TRAb和IL-17等指标均出现阳性表达,且甲状腺自身抗体水平在不同的AITD疾病类型中出现不同变化,患者IL-17水平变化早于甲状腺自身抗体出现异常变化具有警示意义.结论妊娠期甲状腺功能相关指标、甲状腺自身抗体及IL-17水平与妊娠期母体AITD的诊断及鉴别密切相关,IL-17早于自身抗体出现异常具有提示作用,临床上可采用这些检测指标在孕期全程进行AITD的筛查及监测.  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3~4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰~ -7.8‰, PDB) and matrix dolomites (-6.6‰~ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084~0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078~0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.  相似文献

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

Quality traits in wheat (Triticum aestirum L.) were studied by quantitative trait locus (QTL) analysis in a recombinant inbred line (RIL) population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross (ChSh). Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献
