探究不同采血部位对血常规检验准确性的影响。将在甘肃省定西市中医院进行血常规检验的180例患者按照检验先后顺序分为静脉血组和末梢血组，各90例。其中静脉血组采集肘静脉血进行检验，末梢血组采集指尖血检验。对比2组患者血常规各项指标[白细胞（WBC）、红细胞（RBC）、红细胞比容（Hct）、血红蛋白（Hb）、血小板计数（PLT）、平均红细胞血红蛋白浓度（MCHC）、平均红细胞体积（MCV）]水平，血液标本合格率、准确率。静脉血组患者WBC水平明显低于末梢血组（P<0.05）,RBC、Hct、Hb、PLT、MCHC、MCV、NRUT、BASON、EOS、LYMPHN、MONON水平明显高于末梢血组（P<0.05）。静脉血组检验准确率、合格率分别为97.78%、97.78%均明显高于末梢血组87.79%、80.00%(P<0.05)。对患者进行血常规检验时，取肘静脉血进行检验能够明显提高检验准确率、合格率，应用价值较高。     

不同采血方法对Wistar大鼠血常规的影响

摘要:目的　探讨不同采血方法对Wistar大鼠血常规测定结果的影响。 方法　40只SPF级Wistar大鼠顺序进行断尾采血、眼内眦采血和腹主动脉采血,用光电血细胞分析仪进行检测,3种采血方法的检测结果两两比较,进行配对t 检验。 结果　断尾采血白细胞计数最高,其次为眼内眦采血,腹主动脉采血白细胞最低,约为断尾采血的1/3,3种采血途径相互之间差异都极显著(P 0.05),而雌性大鼠断尾采血和眼内眦采血间差异极显著(P0.05)。血小板计数方面,末梢血(断尾、眼内眦采血)极显著低于腹主动脉(P0.05)。 结论　不同采血方法血常规检测结果具有较大统计学差异,应建立各自的背景数据以进行统一比较。     

不同采血方法用于血常规检验中的临床价值

探究不同采血方法用于血常规检验中的临床价值。选取甘肃省泾川县高平中心卫生院进行常规体检的健康体检者264人作为研究对象,随机编号并分为两组,对照组和观察组各132人。所有研究对象均于采血前12h禁止饮食,对照组进行静脉采血,观察组进行末梢采血,于采血后1个小时内将血液样品送至实验室进行检查,对比两组血液样本血常规检查结果。两组血常规结果相比较,观察组各项均明显低于对照组,差异有统计学意义(P0.05)。静脉采血与末梢采血均能用于临床血常规检验中,其中静脉采血各项结果较末梢采血更高,稳定性更强,然而婴幼儿由于采血时配合度较低,且静脉采血量较大,因此静脉采血较困难,多采用末梢采血,方便快捷。临床进行采血时应综合考虑各项因素进行采血。     

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。

探讨自体输血技术与少白细胞异体输血对择期手术患者免疫功能及凝血功能的影响。选取手术患者124例作为研究对象,按照随机数字表法将其分为对照组与观察组各62例,对照组于术中进行少白细胞异体血液回输(血液来源为中心血站),观察组在术前2周内采集自体血,于术中进行自体血回输,观察两组患者手术前后免疫功能、凝血功能及血清炎性因子水平变化情况。(1)术后观察组T淋巴细胞亚群CD3+、CD4+、CD4+/CD8+、自然杀伤细胞(NK)数量明显高于对照组(P0.05),CD8+数量显著低于对照组(P0.05)。(2)术后观察组凝血酶原时间(PT)、凝血酶时间(TT)、纤维蛋白原(FIB)、活化部分凝血活酶时间(APTT)指标均显著优于对照组(P0.05)。(3)两组术后白细胞介素(IL)-6水平无显差异(P0.05),观察组白细胞介素(IL)-2,前列腺素E2(PGE2)及肿瘤坏死因子(TNF-a)水平明显低于对照组(P0.05)。自体输血技术避免了少白细胞异体输血给手术患者带来的免疫细胞抑制,且对机体凝血功能无显著影响,是一种安全有效的输血方式。     

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.     

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.     

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.     

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

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.

橡胶颗粒沥青混合料低温抗裂性试验研究

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.     

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.     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

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.
