目的探讨急性冠脉综合征(ACS)中血清可溶性生长刺激表达基因2蛋白(Soluble growth stimulator gene 2protein,s ST2)、超敏C反应蛋白(High sensitive C reaction protein,Hs CRP)、中性粒细胞和淋巴细胞计数比值(Neutrophil to lymphocyte ratio,NLR)与冠脉病变程度的相关性.方法将173例冠心病患者分为急性冠脉综合征(ACS)组(110例,实验组)和稳定型心绞痛(SA)组(64例,对照组),ACS患者中包括急性心肌梗死(AMI)组54例和不稳定性心绞痛(UA)组56例,均行s ST2、Hs CRP、血常规水平检测,比较各组间血清s ST2、Hs CRP及NLR,分析其与冠脉病变严重程度(冠脉病变支数和Gensini积分)的相关性.结果 ACS组s ST2、Hs CRP及NLR均高于SA组(P0.05); AMI组s ST2、Hs CRP及NLR均高UA组(P0.05); ACS组s ST2与Hs CRP、NLR呈正相关(P0.05); s ST2、Hs CRP及NLR与ACS患者在不同冠脉病变支数之间差异无统计学意义(P 0.05); ACS组s ST2、Hs CRP及NLR与Gensini积分之间均呈正相关(P0.05);回归分析显示:s ST2、NLR是ACS冠脉病变严重程度的预测因子.结论 s ST2、Hs CRP、NLR的水平随着ACS病情进展而逐渐升高,考虑与冠脉粥样斑块的不稳定性有关; s ST2和NLR是ACS冠脉病变程度的预测因子,但s ST2的参考价值更大.  相似文献

目的探讨中性粒细胞与淋巴细胞比值(NLR)在预测急性胰腺炎(AP)严重程度及器官衰竭中的临床价值.方法回顾性分析141例AP患者住院当天(NLR-0)和入院后24 h(NLR-1)、48 h(NLR-2)、72 h(NLR-3) NLR值;根据AP患者严重程度分为MAP组(96例)及SAP组(45例),根据是否发生器官衰竭分为器官衰竭(-)组(117例)及器官衰竭(+)组(24例),采用ROC曲线比较NLR预测能力.结果 MAP组NLR-0,NLR-1,NLR-2,NLR-3的NLR中位数均低于SAP组(P0. 05);器官衰竭(-)组NLR-0,NLR-1,NLR-2,NLR-3的NLR中位数均低于器官衰竭(+)组(P0. 05); NLR在NLR-1时预测AP患者严重程度(AUC:0. 714,最佳截断值5. 18)及器官衰竭发生率(AUC:0. 739,最佳截断值4. 81)的准确度最高.结论 NLR入院24 h预测AP严重程度及器官衰竭发生的准确性最高.  相似文献

目的:观察在治疗慢性阻塞性肺疾病急性加重期(AECOPD)时全身应用糖皮质激素对痰上清液和血清中白介素8(IL-8)和白三烯B4(LTB4)及肺功能的影响。方法:将33例AECOPD患者随机分为治疗组17例,对照组16例。两组均给予常规治疗,同时治疗组给予静脉和口服甲泼尼龙或泼尼松,观察比较两组治疗前后痰上清液和血清中IL-8和LTB4水平、肺功能及呼吸困难(VAS)改善情况。结果:治疗前,痰上清液和血清中IL-8、LTB4水平均高于治疗后,二者间有直线相关关系;且与第1秒钟用力呼气容积(FEV1)、第1秒钟用力呼气容积占预计值百分比(FEV1%)、第1秒钟用力呼气容积与用力肺活量的比值(FEV1/FVC)间有负相关(P0.05)。治疗后,痰上清液IL-8、LTB4的变化与痰中性粒细胞百分比(Neu%)、VAS的变化有显著相关性(P0.05)。与对照组相比,治疗组呼吸困难症状缓解快,痰中性粒细胞减少、痰上清液和血清中IL-8、LTB4的下降水平、FEV1、FEV1%和FEV1/FVC改善幅度均较大。结论:AECOPD患者IL-8和LTB4水平增高,这些变化与临床症状和肺功能相关。使用激素可减轻炎症反应、改善肺功能和缓解患者临床症状。  相似文献

目的探讨PM2. 5暴露对哮喘大鼠气道形态及FOXP3基因DNA启动子区甲基化的影响。方法选择50只SD大鼠,随机选择10只作为空白对照组,40只采用卵清蛋白激发、致敏构建哮喘模型,并根据PM2. 5干预剂量的不同,进一步分为单纯哮喘组、低剂量组、中剂量组、高剂量组,比较不同剂量PM2. 5对哮喘大鼠的病程进展影响。结果 1)与对照组及单纯哮喘组相比,所有PM2. 5干预组大鼠的体质量均明显较低(P 0. 05)。(2)与对照组相比,哮喘组肺泡灌洗液内细胞总数升高最显著,低、中剂量干预组也明显升高,但高剂量干预组无明显变化(P> 0. 05)。与对照组及哮喘组比较,随着PM2. 5干预剂量的升高,大鼠BALF内的嗜酸性粒细胞、中性粒细胞、淋巴细胞计数也呈逐渐上升趋势,巨噬细胞呈逐渐下降趋势,差异均具有统计学意义(P <0. 05)。(3)对照组、哮喘组、低剂量组、中剂量组、高中剂量组的FOXP3基因DNA启动子区的甲基化水平分别为(7. 24±0. 91)、(5. 04±3. 08)、(1. 87±1. 46)、(1. 57±0. 64)、(2. 04±1. 14),FOXP3 mRNA相对表达量分别为(1. 02±0. 18)、(0. 81±0. 19)、(0. 62±0. 15)、(0. 53±0. 14)、(0. 32±0. 04),随着PM2. 5干预剂量的提高,大鼠的FOXP3基因DNA启动子区的甲基化水平及FOXP3 mRNA相对表达量均逐渐降低。结论 PM 2. 5对哮喘大鼠的损伤有一定的剂量依赖性,这可能与调低FOXP3基因DNA启动子区甲基化水平及FOXP3 mRNA相对表达量有关。  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

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  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 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

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

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

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献
