摘要
                
                    脑利钠肽(BNP)是利钠肽系统中的重要成员之一。BNP是一种包含了32个氨基酸的多肽,于1998年被日本学者从猪脑中发现并提取出来。它主要由心室肌细胞受压分泌,故可以反映左心室壁承受的压力大小。BNP可产生排钠利尿效应,参与调节水、电解质平衡,减少血浆容量;同时还可扩张血管,从而降低体循环血管阻力。有大量研究显示,血浆BNP水平在充血性心力衰竭中增高,因此它可作为心衰的有效监测指标之一,并且在临床上得到了广泛应用。此外,BNP还可作为早期心血管疾病的筛查高危因素。近年来BNP在诊疗心血管疾病、呼吸困难、肺栓塞、慢性阻塞性肺疾病和肺癌过程中均显示出重要作用。现就BNP在上述多学科领域中运用的新进展作一综述。
                
                BNP(Brain natriuretic peptide) is an important member of natriuretic peptide system.It is a 32-amino acid polypep-tide.It was firstly discovered and extracted in porcine brain in Japan.It is mainly from secretion in the cardiac ventricles in response to dilatation or an increase of pressure,so it can reflect the pressure of the left ventricular wall.Its biological function is a tension-decreasing effect based on natriuresis,diuresis and vasodilatation effects.A lot of experimental evidences revealed that the plasma concentration of BNP was raised in congestive heart failure,so it is an effective marker for monitoring heart failure,widely used in clinical practice.Fur-ther,BNP could be used to identify patients who are at higher risk for developing cardiovascular events.This article reviews the current state of the BNP in diagnosing and treating cardiovascular disease,dyspnea,pulmonary embolism,chronic obstructive pulmonary disease and lung cancer.
