文题释义:
脐带间充质干细胞移植的优势:①
无伦理问题,来源广泛,易采集,易扩增。②具有更强的增殖能力,比骨髓间充质干细胞快数倍。③是一种更原始的间充质干细胞群。④能分泌粒细胞集落刺激因子、粒-巨噬细胞集落刺激因子等。
缺血再灌注损伤严重程度的影响因素:①缺血时间:因为所有器官都能耐受一定时间的缺血。缺血时间短,恢复血供后可无明显的再灌注损伤。②侧支循环:缺血后侧支循环容易形成者,可因缩短缺血时间和减轻缺血程度,不易发生再灌注损伤。③需氧程度:因氧易接受电子,形成氧自由基增多.因此,对氧需求高者,较易发生再灌注损伤。④再灌注压力:再灌注压力愈高造成的再灌注损伤愈严重。


摘要
背景:
异丙酚具有脑保护作用,而脐血间充质干细胞具有较高分化潜能,两者联用可能对脑缺血再灌注损伤有更好的治疗效果。
目的:评价异丙酚预处理与脐血间充质干细胞移植联用对大鼠脑缺血再灌注损伤后神经再生的影响。
方法:将63只SD大鼠随机等分为模型组、异丙酚组和联合组。所有大鼠以内栓线法建立脑缺血再灌注损伤模型。异丙酚组大鼠于损伤前1 d腹腔注射100 mg/kg异丙酚。联合组大鼠损伤前1 d注射异丙酚(100 mg/kg),并于大鼠尾部静脉静注脐血间充质干细胞(2×109 L-1) 0.5 mL。
结果与结论:①与模型组相比,异丙酚组和联合组大鼠脑组织病理损伤明显减轻,海马组织中survivn基因表达水平上升,神经功能明显改善;②联合组大鼠上述指标优于异丙酚组,同时与异丙酚组相比,联合组大鼠血清中丙二醛含量较低,而超氧化物歧化酶含量较高;③说明异丙酚预处理联合脐血间充质干细胞移植有效改善脑缺血再灌注损伤,且效果优于单纯异丙酚预处理。

Abstract:

BACKGROUND: As propofol has a neuroprotective effect, and umbilical cord blood mesenchymal stem cells have a high differentiation potential, their combination will have a better therapeutic effect on cerebral ischemia-reperfusion injury.
OBJECTIVE: To study the effect of propofol pretreatment combined with umbilical blood mesenchymal stem cell transplantation on cerebral ischemia-reperfusion injury in rats.
METHODS: Sixty-three Sprague-Dawley rats were randomized into model, propofol, and combined group (n=21 per group). Rat models of cerebral ischemia-reperfusion injury were made using ligation of the middle cerebral artery occlusion in the three groups. Rats in the combined group were given 100 mg/kg propofol injection at 1 day before injury and injection of umbilical blood mesenchymal stem cells via the tail vein (0.5 mL, 2×109/L).
RESULTS AND CONCLUSION: Compared with the model group, the neurological function was improved significantly in the propofol and combined group, especially in the latter one, presenting with a remarkable mitigation in brain injury and an increased level of survivn mRNA in the rat hippocampus. The content of serum malondialdehyde was lower but the activity of superoxide dismutase was higher in the combined group compared with the propofol group. These findings indicate that propofol pretreatment combined with umbilical blood mesenchymal stem cell transplantation has better therapeutic effects than propofol pretreamtnet alone for improving cerebral ischemia-reperfusion injury in rats.
