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:探讨不同胆汁引流方式对梗阻性黄疸兔血清内毒素与免疫功能的影响。方法:将36只新西兰白兔随机均分为假手术组、外引流组、内引流组。外引流组与内引流组先建立可逆型梗阻性黄疸模型,7 d后解除梗阻,分别行胆汁外引流与内引流;假手术组按相同时间间隔行2次假手术。各组分别于造模前、造模后7 d、引流术后7 d采血,检测肝功能指标、血清内毒素水平、血中CD4+CD25+调节性T细胞的比例。结果:假手术组各时间点各项指标均无明显变化(均P0.05);造模后7 d,外引流组与内引流组血清胆红素、转氨酶、内毒素水平均较造模前明显升高,血CD4+CD25+调节性T细胞比例较造模前明显降低(均P0.05);行引流术7 d后,外引流组与内引流组肝功能指标、内毒素水平、CD4+CD25+调节性T细胞比例均较造模后7 d明显恢复,但内引流组后两项指标的恢复程度均明显优于外引流组(均P0.05)。结论:胆汁内引流较胆汁外引流更有利于梗阻性黄疸内毒素清除与机体免疫功能快速恢复。
