3TSR对胰腺癌的抑制作用及机制探讨

目的研究血管形成抑制剂3TSR在体内外对胰腺癌的抑制作用,并初步探讨其机制。方法分别在体外培养条件下比较对照组、3TSR、键择(Gem)和3TSR Gem组对胰腺癌MIAPaCa-2细胞增殖及凋亡的影响,以及对裸鼠原位移植瘤肿瘤体积、细胞增殖指数及凋亡的影响。结果体外培养时3TSR对胰腺癌细胞无增殖抑制及诱导凋亡的作用,而Gem对胰腺癌细胞具有明显的抑制增殖及诱导凋亡的作用,但3TSR与Gem在体外无协同作用。体内实验时3TSR组、Gem组和3TSR Gem组肿瘤体积较对照组分别缩小70.1%,79.3%和84.9%;3TSR组、Gem组和3TSR Gem组胰腺癌细胞增殖指数分别为(19.7±3.1)%,(8.1±1.9)%和(13.2±4.2)%,其中3TSR组增殖指数与对照组比较差异无统计学意义,而Gem组和3TSR Gem组细胞增殖指数明显小于对照组和3TSR组(P<0.05);3TSR组、Gem组和3TSR Gem组胰腺癌细胞凋亡率分别为(5.0±2.2)%,(21.1±4.2)%和(22.8±4.2)%,其中3TSR组胰腺癌细胞凋亡率与对照组比较差异无统计学意义(P<0.05),而Gem组和3TSR Gem组细胞凋亡率显著大于对照组和3TSR组(P<0.05);3TSR组及3TSR Gem组血管内皮细胞凋亡率又高于对照组和Gem组(P<0.05)。结论3TSR体内外对胰腺癌细胞无直接增殖抑制及诱导凋亡作用,但能显著减少肿瘤体积,其机制可能与诱导内皮细胞凋亡有关;3TSR与化疗药物Gem合用未明显提高胰腺癌的治疗效果。

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.
