末梢血和静脉血在血常规检验中的应用效果对比

观察分析血常规检验中采集末梢血、静脉血两种不同血液样本的应用效果。研究对象从2018年1月～2018年12月期间在高台县人民医院接受健康体检人员中随机选取48例,采集48例健康体检者末梢血、静脉血,统一进行血常规检验,对比2组血常规检验结果,分析不同时间静脉血血常规检验结果。结果:2组红细胞(RBC)、白细胞(WBC)、红细胞平均血红蛋白浓度(MCHC)、血小板(PLT)、血红蛋白(HGB)检验结果比较,差异均有统计学意义(P0.05);RBC、WBC、HGB三项指标不同时间检验结果比较,差异均无统计学意义(P0.05),PLT此项指标0h、1h、3h不同时间检验结果比较,差异均无统计学意义(P0.05),6h检验结果明显降低(P0.05)。血常规检验采集静脉血作为血液样本,其测定结果更加优异,同时具有更为满意的稳定性。     

末梢血与静脉血不同血液采集方式在血常规检验中的应用效果

探讨末梢血与静脉血不同血液采集方式在血常规检验中的应用效果。选取天水市第四人民医院接收的行血常规检验的患者118例,且每例患者均分别采集末梢血与静脉血各1份,其中将118例静脉血样本作为静脉血组,将118例末梢血样本作为末梢血组。比较2组血常规检测结果。静脉血组WBC、MCH数值较末梢血组低(P0.05),RBC、Hb、HCT、PLT、MCHC及MCV数值较末梢血组高(P0.05);分析静脉血样本不同时间段检测结果发现,3h内检测与即刻检测比较,WBC、RBC、PLT与MXD数值均无明显差异(P0.05),6h后检测与即刻检测比较,WBC、RBC差异不大(P0.05),PLT数值有所下降(P0.05),MXD数值有所升高(P0.05)。临床上使用不同血液采集方式进行血常规检测,其检测结果存在一定程度的差异。但相较于末梢血检测而言,静脉血检测结果准确率更高。因此,应采集静脉血进行血常规检测。与此同时,血常规检测结果受采集后样本放置时间影响,故为避免误差,应在3h内完成血常规检测工作。     

血液检验在贫血患者中的鉴别诊断与临床意义分析

分析血液检验在贫血患者中的鉴别诊断与临床意义。选取2018年7月—2020年1月医院收治的贫血患者150例作为研究组，将其分为缺铁性贫血组、地中海贫血组各75例，另选取同期来院体检的健康人群75例作为对照组。比较2组血液检测指标，地中海贫血组和缺铁性贫血组血液检测指标、叶酸、维生素B12、铁蛋白指标。RBC、RBC/MCV无统计学意义（P>0.05），平均红细胞血红蛋白（MCH）、平均红细胞容积（MCV）、血红蛋白（Hb）低于对照组（P<0.05）,RDW高于对照组（P<0.05）;MCV无统计学意义（P>0.05），缺铁性贫血组MCH、RDW高于地中海贫血组（P<0.05）,RBC、Hb、RBC/MCV低于地中海贫血组（P<0.05）；研究组叶酸，维生素B12，铁蛋白均低于对照组（P<0.05）。在贫血患者的鉴别诊断过程当中，血液检验具有一定的临床意义，更好地帮助医生做出准确的临床诊断，应当进一步推广应用。     

镉、豆磺隆联合胁迫下黑土质量的变化

采用盆栽试验研究了黑土Cd单一污染和Cd-豆磺隆复合污染胁迫与上壤脲酶、磷酸酶活性的关系,同时分为拔节期、开花期和成熟期三个时期研究了在有或无污染物作用下这2种酶活性的动态变化规律.结果表明,无论是在有或无豆磺隆胁迫下,随着Cd污染浓度的增加,脲酶活性呈现出明显的下降趋势,酸性磷酸酶活性变化相对于脲酶比较稳定.通过拟合方程可知,2种酶活性变化在一定程度上可以反映Cd或Cd-豆磺隆的污染状况.在小麦的整个生长期内,当Cd污染浓度为5、10、30 mg·kg-1时,2种酶活性均呈现先升高后下降的趋势;而在高浓度(50、100mg·kg-1)Cd作用下,2种酶活性始终呈现升高的趋势.     

高强度复合式训练对健美操选手体脂及组织损伤的影响研究

目的:探讨高强度训练(HIT)与高负荷训练(HVT),对健美操运动员组织损伤的影响.方法:针对健美操选手进行为期12周高强度复合式训练,并于运动前、训练中、训练后对受试者血清肌肉损伤的生化指标、体脂率等进行监测.结果:(1)高强度复合式训练能显著降低受试者体质量、体脂、甘油三酯、总胆固醇及尿素氮浓度;(2)提升血液葡萄糖、乳酸、肌酸酐浓度,增强天门冬胺酸转胺酶及肌酸激酶活性;(3)血液中的肌肉损伤指标值的提升与体脂下降率呈负相关,这暗示高强度复合式训练有利于肌肉再生,从而促使脂肪组织下降.结论:12周高强度复合式训练使健美操选手体脂明显减少、血液中肌肉损伤指标值提升,表明该训练方式可以促使肌肉再生,吸引全身含碳资源重新分配,使脂肪组织下降、肌肉组织增加,强度越高,碳资源重新分配效果越好.

分析血液常规检验在贫血鉴别诊断中的应用效果。从兰州市第三人民医院2015年2月-2017年3月收治贫血患者中抽取84例作为观察组,按贫血类型分成两组:地中海贫血组、缺铁性贫血组,并将同期体检健康者40例作为对照组,对其进行血液常规检验,统计检验结果。地中海贫血组患者的红细胞、红细胞分布宽度高于缺铁性贫血组,缺铁性贫血组患者RBC/MCV指标高于地中海贫血组和对照组,对照组血红蛋白、平均红细胞血红蛋白量、红细胞平均体积高于观察组,组间统计有意义(P0.05);地中海贫血组患者符合率为78.6%,灵敏度为92.9%,特异性为69.0%。缺铁性贫血组患者符合率为81.0%,灵敏度为95.2%,特异性为71.4%,组间统计有意义(P0.05)。贫血鉴别诊断中实施血液常规检查,不但能保证检验结果,还能为疾病诊断提供便利,值得应用。     

Markedness and its Interpretation in Language Use

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.     

Features of Women's language

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.     

An Analysis of Catherine＇s Character——Wuthering Heights

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.     

Lower Paleozoic oil relationships within Williston Basin, Canada

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.     

低渗透非均质砂岩油藏启动压力梯度研究

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。     

On Tragic Consciousness In The Works By Ernest Hemingway

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.

Achieving Unusual States of Matter Under High Pressure

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-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

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-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

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
