不同门奇断流术式对门静脉高压症犬食管下段血管再生的影响

Objective To explore the effect on blood vessel regeneration of distal esophagus in ca-nines of portal hypertension with liver cirrhosis after different procedures with paraesophagastrie devascular-ization. Methods Portal hypertension models were produced in canines by subcutaneous injection of 60% CC14 combined with food restriction. Forty eight model canines were randomly divided into 4 groups: group A, traditional paraesophagastrie devascularization;group B, selective paraesophagastric devascularization;group C, paraesophagastric devascularization plus distal esophageal transaction and reanastomosis with sta-pler;group D,control group. Every group had 12 canines which were randomly divided into A1 ,B1 ,C1 ,D1, A2,B2,C2 and D2 groups after the operation. Canines in groups A1 ,B1 ,C1 and D1 were executed at first month after the operation,and those in groups A2, B2, C2 and D2 were executed at the 6th month after the operation. The distal esophagus was segmented when the canines were executed. The upside and downside of the stoma in group C were distinguished and signed as Ca and Cb. Immunohistochemieal methods were used to detect VEGF,CD34 and FVⅧ-Rag,blood vessel-related factors,in lower esophagus. Results The expres-sion levels of VEGF and CD34 MVD,FⅧ-Rag MVD in groups A1 ,B1 and C1 were lower than those in group D1 one month after the operation (P <0.05). All the indices in group B1 were lower than those in groups A1 and Clb,but higher than those in group Cla (P <0.05). The indices in group Cla were lower than those in group C1b (P < 0.05 ). The indices in groups A2 and B2 were higher than those in groups A1 and B1, re-spectively at the 6th month after the operation (P <0.05). They were higer in outer membrane in group C1a than in group C2a (P <0.05). The indices in group C2b were higher than those in group Clb (P<0.05). Conclusion At the first month after operation, the expression of blood vessel-related factors was declined in three different procedures of paraesophagastric devascularization,which indicated that all three different pro-cedures could diminish the vessels in distal esophagus. The effect in group C was most obvious among all groups. At the 6th month after traditional paraesophagastrie devascularization and selective paraesophagastrie devascularization, the expression of blood vessel-related factors in distal esophagus was declined. But there were no significant changes in the expression of blood vessel-related factors in distal esophagus after parae-sophagastric devascularization plus distal esophageal transaction and reanastomosis with stapler. It indicated that the blood vessel regeneration in paraesophagastric devascularization pins distal esophageal transaction and reanastomosis with stapler was inferior to that in other procedures.

目的 检测再生障碍性贫血患者血清中血管内皮生长因子(VEGF)与表皮生长因子(EGF)的浓度,探讨VEGF和EGF在再生障碍性贫血患者血液中的表达及二者之间的关系和意义.方法 应用酶联免疫技术(ELISA法)检测20例再障患者及40名健康人血清中VEGF和EGF浓度.结果 20例再生障碍性贫血患者血清VEGF的含量为50.5±34.8pg/ml,对照组血清VEGF的含量为108.5±50.6 pg/ml,两组比较有统计学意义(P＜0.05).20例再生障碍性贫血患者血清EGF含量为0.15±0.11 μg/L,40例正常对照组血清EGF含量为0.76±0.80 μg/L.结论 再生障碍性贫血患者血清VEGF、EGF浓度显著低于健康对照组,且二者呈显著正相关.     

21例心内直视术后急性心包填塞的临床分析

目的:分析21例心内直视术后急性心包填塞的临床特点,探讨其发生原因、预防、救治及其二次开胸的早期指征。方法:对1991年1月-2005年12月心内直视术(共1096例)后21例急性心包填塞二次开胸(发生率1．92％)病例进行总结分析。结果:急性心包填塞患者经二次剖胸解除心包填塞后17例痊愈出院,4例死亡,二次剖胸手术死亡率为19．05％。二次剖胸手术者所患疾病包括先天性心脏病6例,瓣膜病13例,大血管手术1例,心脏移植1例。结论:减少心内直视术后出血、渗血是避免术后发生急性心包填塞的关键,早期诊断并尽早行二次剖胸手术可明显降低围手术期死亡率。
