摘　　要：[目的]通过观察夏至、冬至大鼠心肌组织心钠肽(atrial natriuretic peptide,ANP)、脑钠肽(brain natriuretic peptide,BNP)、氨基末端脑钠肽前体(N-terminal pro-B-type natriuretic peptide,NT-proBNP)分泌量的不同,探讨“心应夏”理论的生物学基础。[方法]雄性SD大鼠随机分为正常对照组、慢性心力衰竭组、松果腺摘除组、复合模型(慢性心衰+松果腺摘除)组,分别于冬至、夏至两个时间点,采用酶联免疫吸附测定(enzyme-linked immunosorbent assay,ELISA)法检测各组大鼠心肌组织中ANP、BNP、NT-proBNP含量。[结果]正常生理情况下,大鼠心肌组织ANP、BNP、NT-proBNP的分泌量均呈现夏低冬高的季节节律变化;松果腺摘除后,大鼠心肌组织ANP、BNP、NT-proBNP的季节节律差异消失,甚至出现倒置。在慢性心衰条件下,大鼠心肌组织ANP、BNP、NT-proBNP的分泌量呈现夏高冬低的节律变化,摘除松果腺后,原有节律消失。[结论]心肌组织ANP、BNP、NT-proBNP是“心应夏”的重要生物学物质基础,它们的分泌存在夏冬季节的节律变化,慢性心衰的病理状态下则呈现与正常生理状态相反的季节节律,松果腺也参与了“心应夏”的季节调节。[Objective]To investigate the biological basis of the theory of“heart corresponding to summer”by observing the differences in the secretion of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP)and amino-terminal pro-B-type natriuretic peptide(NTproBNP)in the myocardial tissues of the rats at the summer solstice and the winter solstice.[Methods]Specific pathogen free grade male SD rats were randomly divided into 4 groups,which were treated as normal control group,chronic heart failure(CHF)group,pineal gland removal group and composite model(CHF+pineal gland removal)group,and the contents of ANP,BNP and NT-proBNP were detected in myocardial tissues of the rats in each group at the winter solstice and summer solstice time points.[Results]Under normal physiological conditions,the secretion of ANP,BNP and NT-proBNP in rat myocardial tissues showed seasonal rhythmic changes of low in summer and high in winter;after the removal of the pineal gland,the seasonal rhythmic differences of ANP,BNP and NT-proBNP disappeared,and even appeared to be inverted;under the condition of CHF,the secretion of ANP,BNP and NT-proBNP in rat myocardial tissues showed seasonal rhythmic changes of high in summer and low in winter,and the original rhythm disappeared after the removal of the pineal gland.[Conclusion]Myocardial tissue ANP,BNP,NT-proBNP is the important biological material basis of the“heart corresponding to summer”,their secretion of summer and winter seasonal rhythm changes,and the pathological state of CHF show the opposite of the normal state of the seasonal rhythm.At the same time,the pineal gland is involved in the seasonal regulation of the heart corresponding to summer.
