【摘要】：目的：通過(guò)對(duì)心室肌的大體解剖與組織學(xué)研究,比較心肌傳統(tǒng)概念與心肌帶理論的差異。 方法：(1)應(yīng)用大體解剖、組織切片HE染色、虛擬切片掃描方法顯示心室肌的纖維走向及空間結(jié)構(gòu)。(2)將防腐固定后的成人正常心臟順心肌纖維方向分層解剖心肌,使之展開(kāi)成帶,按照解剖的逆步驟將心肌帶應(yīng)用支架還原固定,制作出心肌帶標(biāo)本來(lái)顯示心肌的三維空間結(jié)構(gòu)。 結(jié)果：將防腐固定的成人正常心臟經(jīng)改良的解剖方法解剖,可解剖出一條完整的心肌帶,分為2個(gè)環(huán),4個(gè)段。心肌帶呈螺旋走向。 用大體解剖與組織切片HE染色、虛擬切片掃描顯示右心室肌起始于纖維三角為一條單層肌肉帶,左心室肌分為三層肌纖維起始于纖維三角與纖維環(huán),肌纖維從纖維三角與纖維環(huán)持續(xù)由外向內(nèi)轉(zhuǎn)變呈現(xiàn)為一種交錯(cuò)結(jié)構(gòu),縱行的淺層心肌纖維在心尖以90°的角返回心底方向,構(gòu)成深層心室肌形成肉柱,部分心肌纖維斜、橫行構(gòu)成中層心室肌。三者在心尖呈現(xiàn)出一種螺旋形結(jié)構(gòu),應(yīng)用虛擬切片掃描技術(shù)能完整、清楚地顯示心室肌某一切面的結(jié)構(gòu)走向。 把心肌帶按照解離時(shí)的逆步驟逐步還原,在心肌帶相應(yīng)部位之間用特制有機(jī)玻璃支架固定,顯示出立體的心肌帶螺旋標(biāo)本。 結(jié)論：心肌傳統(tǒng)理論與心肌帶理并未完全沖突,改良的解剖方法能更好顯示出心肌纖維走行及心肌帶的立體螺旋型結(jié)構(gòu)。
[Abstract]:Aim: to compare the traditional concept of myocardium with the theory of myocardial band by studying the gross anatomy and histology of ventricular muscle. Methods: (1) using gross anatomy, HE staining of tissue sections, virtual section scanning method to show the direction of fibers and spatial structure of ventricular muscle. According to the reverse steps of anatomy, the myocardial band was fixed with stent, and the myocardial band specimen was made to display the three-dimensional spatial structure of myocardium. Results: the antiseptic fixed adult normal heart was dissected by modified anatomical method and a complete myocardial band was dissected and divided into two rings and four segments. The myocardial zone is in a spiral direction. With HE staining of gross anatomy and tissue sections, virtual section scanning showed that the right ventricular muscle originated from the fiber triangle into a single-layer muscle band, and the left ventricular muscle was divided into three layers of muscle fibers starting from the fiber triangle and the fibrous ring. The muscle fibers continuously changed from the fiber triangle and the fiber loop to a staggered structure. The longitudinal superficial myocardial fibers returned to the bottom of the heart at an angle of 90 擄at the apex of the heart, forming a fleshy column of the deep ventricular muscle, and some of the myocardial fibers were oblique. Transversal constitutes the middle ventricular muscle. The three showed a spiral structure at the apex of the heart. The virtual slice scanning technique could be used to show clearly the structural direction of a certain section of the ventricular muscle. The myocardial band was gradually reduced in accordance with the inverse steps of dissociation and fixed with a special plexiglass scaffold between the corresponding parts of the myocardial band, showing a three-dimensional spiral specimen of myocardial band. Conclusion: the traditional myocardial theory does not completely conflict with the myocardial band theory. The improved anatomical method can better display the three-dimensional spiral structure of myocardial fiber and myocardial band.
