Blood Pressure and Cerebral Blood Flow

Systemic blood pressure has assumed an identity of its own with a rigid norm, deviation from which causes dismay to the patient and his advisers. The opportunity for hypotensive treatment has enhanced the emotional response of the profession to a raised blood pressure. There are, however, wide variations in blood pressure in any subject, and a wider justifiable range within the community. Emphasis is now more properly placed upon blood flow, and blood pressure which depends upon many factors is itself one of the factors maintaining flow. This underlies the present dynamic attitude to the understanding of the cerebrovascular disturbances, and has offered an explanation of many of the minor and transient forms which these disturbances present.     

恶性血液病血瘀证的研究

探讨恶性血液病患者血瘀证的临床意义。方法 对１１２例恶性血液病患者进行了血瘀证的临床观察和血浆血小板α颗粒蛋白（ＧＭＰ－１４０）及Ｄ－二聚体（Ｄ－Ｄ）的检测。结果 恶性血液病患者中血瘀证的检出率为６９．６４％。血瘀证组血浆ＧＭＰ－１４０及Ｄ－Ｄ检测的水平均显著高于非血瘀证组（Ｐ〈０．０１）。结论 恶性血液病血瘀证患者血小板的激活与消耗增多,并有继发性纤溶存在。血浆ＧＭＰ－１４０及Ｄ－Ｄ的水平与血瘀     

即时检验血糖仪检测指尖血及静脉全血血糖的临床分析

目的：探讨即时检验血糖仪检测指尖血及静脉全血血糖检验结果的临床可行性。方法随机选取该院2011年6月—2012年7月所接收治疗的50例糖尿病患者,采取静脉血和指尖血,采用即时检验血糖仪检测所有患者的血糖数值,同时,还在生化分析仪上进行检测血浆葡萄糖,对比分析两部位生化分析仪检测结果和血样检测结果的偏倚程度。结果即时检验血糖仪指尖血血糖为（9.38±4.28）mmol/L,静脉全血血糖为（9.17±4.05）mmol/L,生化仪测定血浆葡萄糖为（9.96±5.01）mmol/L,三者之间进行统计学分析,差异有统计学意义（P＜0.05）,两部位生化分析仪检测结果和血样检测结果的偏移程度都是负偏倚,其中,偏倚范围最高是13.8%,最低为1.4%,都没有超过20%。静脉全血血糖偏倚显著高于指尖血血糖偏倚,差异具备统计学意义（P＜0.05）。结论对于即时检验血糖仪检测指尖血及静脉全血血糖检验结果的临床可行性,不管是采用静脉采血,还是指尖采血,即时检验血糖的数值都在接受范围内,但是采取指尖血样,检测结果更加接近血浆葡萄糖。     

血荒拷问《献血法》

2011年10月1日,正当全国各省市纷纷为《中国人民共和国献血法》（下称“《献血法》”）颁布实施13周年举办各类纪念活动之际,网络上层出不穷的“血荒”消息无疑为纪念活动蒙上了一重阴影。北京、郑州、合肥、长春……多个城市血库告急。
