相关研究发现异氟醚可引起幼龄大鼠广泛的脑神经元凋亡,且近期发现异氟醚还可以介导海马神经元发生自噬。在前期试验的基础上,选取40只7日龄(P7)SD大鼠幼鼠,随机分为对照组和1.5%异氟醚麻醉2、3、4、6h组,建立实验模型。待麻醉结束后将大鼠安乐死,取脑并分离海马组织。用TUNEL染色、LC3-II免疫组化及Western blot检测等方法检测海马神经元自噬及凋亡情况。试验结果显示,随着异氟醚作用时间的增加,TUNEL染色结果显示,麻醉4h后海马阳性细胞率明显增多,而LC3-II免疫组化结果显示在3、4h时阳性率较高,6h有所下降;与对照组相比,活化的Caspase-3表达量逐渐增加;Bcl-2表达量逐渐降低。Beclin-1和LC3-II/I表达量先升高后下降,并且在异氟醚作用3h时表达量明显升高(P<0.05);此外,与异氟醚麻醉3、4h时相比,Beclin-1在麻醉6h时表达量明显下降,而Caspase-3表达量明显升高(P<0.05)。试验结果表明,异氟醚不仅可以引起幼龄SD大鼠海马神经元广泛凋亡,而且还能诱导海马神经元自噬,凋亡水平随麻醉时间延长逐渐加强,而自噬水平先升高后降低。自噬在异氟醚诱导的海马区神经元凋亡中可能发挥着保护性作用。

课题组前期研制出一种新型携带多种药物成分的内支撑物,并将其应用于试验犬的肠管吻合术中,此研究表明采用内支撑物应用于犬肠管吻合术,与传统吻合术比较,可降低手术操作的难度,缩短吻合时间,且术后无明显并发症,愈合良好。为了进一步探讨这种新吻合技术的可行性及相关机制,课题组从腹腔黏连评分、吻合口爆破压和羟脯氨酸含量等方面对2组犬的术后愈合情况进行比较研究。以健康本地犬为试验动物,分为内置支撑物组(NZ组,12只)和传统手术组(CS组,12只),分别在术后3,7,14,28d,剖腹探查,观察吻合部位愈合情况,进行腹腔黏连评分,并对吻合口爆破压、吻合口组织中羟脯氨酸含量等项目进行检测。腹腔黏连结果表明术后7,14,28d,CS组的腹腔黏连评分显著高于NZ组,结果具有统计学意义(P0.05);术后7,14d,CS组的吻合口爆破压显著低于NZ组(P0.05);2组的羟脯氨酸含量均随时间的增长而增加,而在各个时间点上2组相比无显著性差异(P>0.05)。最终试验结果表明,相对传统小动物肠管吻合术而言,使用内支撑物进行该手术能减少术后黏连,吻合部位的愈合情况更为良好。
