长期以来,脑出血被公认为是死亡率和致残率很高的急性脑血管疾病,传统治疗手段及理论研究相对滞后,治疗效果也不尽人意[1],早期手术治疗仍然存在较大争议[2]。近年来,重组人活性凝血因子VII(rFVIIa)治疗急性期脑出血成为一个新的研究热点,各国学者围绕rFVIIa开展了一系列临床试验,以期望在传统的脑出血治疗上取得突破,试验结果令人鼓舞。rFVIIa的概述人凝血因子VII(FVII)是由肝脏合成的一种维生素K依赖的单链糖蛋白酶原,在体内作为外源性凝血途径的启动因子,发挥着重要的作用。正常人血浆中FVII的浓度很低。血管发生病变后,组织… 相似文献

Nocturnal blood pressure patterns are expressed as a consequence of both intrinsic circadian rhythms and the quantity and quality of sleep. A range of neurohumoral factors have been either inferred or definitively proven to influence the circadian blood pressure pattern. In this regard, changes in atrial natriuretic peptide, plasma renin activity and plasma aldosterone have been evaluated as to the influence each might have in determining diurnal blood pressure patterns. As an example, a clear pattern of nocturnal increase in plasma renin activity has been observed; however, the relationship between this change and nocturnal blood pressure remains vague. In contrast, change in sympathetic nervous system activity has most commonly been associated with the conversion of a pattern of nocturnal dips in blood pressure to one of non-dipping. Increasingly, dietary intake patterns, characterized by high sodium or low potassium content, or both, are recognized as modifiers of the normal decrease in nocturnal blood pressure, again in favor of producing a non-dipping pattern. The impact of these nutritional patterns on nocturnal blood pressure change is recognized to be most prominent in salt-sensitive individuals. Modifications of dietary sodium intake, such that it is decreased or potassium intake is increased, or both, are now recognized as means by which a nocturnal non-dipping pattern can be converted to a dipping pattern. Additional studies of an integrative nature will be necessary to obtain more complete definition of the dynamic interplay between nutrition and various neurohumoral axes in determining how nocturnal blood pressure patterns are expressed. 相似文献
