目的探讨单一腹主动脉阻断式下无血切肝术式的效果。方法1980年以来,我们进行了一系列常温下单一腹主动脉阻断(SAAC)实验研究,其结果首次证实犬SAAC安全时限为25min。在此时限内,仅有轻度可逆性的血液动力学,酸碱平衡、血液生化,以及主... 目的探讨单一腹主动脉阻断式下无血切肝术式的效果。方法1980年以来,我们进行了一系列常温下单一腹主动脉阻断(SAAC)实验研究,其结果首次证实犬SAAC安全时限为25min。在此时限内,仅有轻度可逆性的血液动力学,酸碱平衡、血液生化,以及主要脏器的超微结构变化;超过此时限,则将会导致不可逆难以代偿的体内严重病理生理变化。我们还进行了一系列SAAC式腹部无血外科实验研究。本实验中18犬被随机分成3组(各组n=6)做下列对照研究:单一腹主动脉阻断式无血切肝术"SAAC-BH式";Pringle’s式切肝术;Heaney式无血切肝术。结果(1)3组切肝术平均时间:A组5.80min,B组5.85min,C组5.90min,3组组间比较无显著性差异(P>0.05);(2)3组术中切肝平均出血量:A组5.60mL,B组28.40mL,C组5.80mL,A、C两组与B组相比较存在显著性差异(P<0.05);(3)A组6犬术后均苏醒与进食,并能长期生存;B、C组各有1犬与2犬死于术后1周之内;余犬术后均能苏醒与进食,并能长期生存;(4)SAAC-BH组阻断后与撤钳后均发生某些生理生化与脏器超微结构变化,均在可逆性范围之内。结论在严格遵循"二叉树耐受法则"条件下,SAAC-BH式(膈下,腹腔干动脉之上水平)像Heaney式一样均能达到无血切肝之目的,且能安全施行,控制术中出血优于Pringle’s式切肝式。本文提出现代肝脏切除术发展经过4个阶段,并将SAAC-BH式与现有切肝术各式家系做了详细利弊分析。最后指出,我国腹主动脉阻断式无血外科学科在国际上已率先建立。 展开更多

Robert Lowell called him "the most important Irish poet since Yeats". This paper gives an overview on Seamus Heaney from four parts: first part gives a brief introduction of Seamus Heaney, the second part introduces Seamus Heaney's characters and contributions on poetry, the third part briefly states Heaney's postcolonial consciousness. The forth part introduces Seamus Heaney's first book The Death of Naturalist and gives a detailed analysis of Blackberry Picking. 展开更多

In the decade after 1969,Heaney reached the climax of his poetry composition,in which he published four volumes of poetry,Door into the Dark,Wintering Out,North and Field Work to explore the nature and origin of the hatred and violence in Northern Ireland.The thesis focuses on five representative bog poems written in the period to explain according to Homi K.Bhabha’s postcolonial theory how the bog bodies configurate the hybrid space and how it reflects the Third Space of Northern Ireland.Furthermore,the thesis argues that from the construction of the Third Space,Heaney achieves temporary harmony between his artistic and realistic responsibility. 展开更多
