文题释义:
慢性阻塞性肺疾病:
是一种常见的以持续气流受限为特征的可以预防和治疗的疾病,气流受限进行性发展,与气道和肺脏对有毒颗粒或气体的慢性炎性反应增强有关。
间充质干细胞减轻肺部炎症反应:大量研究证实间充质干细胞可以分化成肺上皮细胞,并诱导其表达气道和/或肺泡上皮细胞的标记,可表达HLA Ⅰ,HLA Ⅱ以及其他共刺激分子,使得间充质干细胞可以成功逃避机体免疫监测。此外,它可以在损伤组织局部分泌一些生长因子和细胞因子,提高自由基清除酶的活性,增强机体的抗氧化能力,减轻脂质过氧化引起的损伤。另有研究表明到达损伤肺组织中的间充质干细胞能在下调促炎因子表达的同时上调抗炎细胞因子的表达,从而起到减少甚至是中止炎症的作用。

 

摘要
背景:
慢性阻塞性肺疾病是一种具有气流受限特征的以炎症为核心的慢性呼吸系统疾病。
目的:探讨脂肪间充质干细胞对慢性阻塞性肺疾病大鼠的治疗作用。
方法:健康雄性SD大鼠60只随机分成3组(n=20),治疗组和模型组大鼠通过烟熏及气管内注入脂多糖的方法建立慢性阻塞性肺疾病模型,对照组大鼠不进行任何处理。造模后治疗组大鼠经尾静脉注射CM-Dil 标记的脂肪间充质干细胞,模型组及对照组给予等量生理盐水,移植后14 d,检测大鼠肺通气功能、炎症因子水平和肺组织病理学变化。
结果与结论:①与对照组比较,模型组和治疗组肺功能明显下降,治疗组肺功能较模型组明显改善(P < 0.05);②治疗组肺泡灌洗液中白细胞总数、巨噬细胞数及中性粒细胞数均显著低于模型组(P < 0.05);③治疗组肺泡灌洗液中白细胞介素8、肿瘤坏死因子α、C-反应蛋白水平低于模型组(P < 0.05);④与模型组相比,治疗组血清中超氧化物歧化酶活性显著增高、丙二醛水平显著降低(P < 0.05);⑤治疗组较模型组肺气肿样改变减轻;⑥CM-Dil 标记的脂肪间充质干细胞能够归巢到慢性阻塞性肺疾病大鼠肺组织并存活;⑦结果表明,脂肪间充质干细胞移植能改善慢性阻塞性肺疾病大鼠肺功能,减轻炎症反应,具有一定治疗作用。

Abstract:

BACKGROUND: Chronic obstructive pulmonary disease is progressive respiratory disease characterized by airflow limitation.
OBJECTIVE: To investigate the therapeutic effect of adipose-derived mesenchymal stem cell transplantation in rats with chronic obstructive pulmonary disease.
METHODS: Sixty healthy male Sprague-Dawley rats were randomly divided into control, model and treatment groups (n=20 per group). Rat models of chronic obstructive pulmonary disease were made in the model and treatment group, while no treatment was done in the control group. After modeling, rats in the treatment group were given tail vein injection of CM-Dil-labeled adipose-derived mesenchymal stem cells, and rats in the model and control groups given the same amount of normal saline. Rat pulmonary ventilation function, inflammatory factor level and pathological changes of the lung were detected at 14 days after cell transplantation.
RESULTS AND CONCLUSION: After modeling, reduced lung function was found in rats with chronic obstructive pulmonary disease, but the cell transplantation significantly improved this reduction (P < 0.05). Compared with the model group, significantly reduced indexes were visible in the treatment group (P < 0.05), including the total number of white blood cells, the number of macrophages and neutrophils, levels of interleukin-8, tumor necrosis factor α and C-reactive protein in the bronchoalveolar lavage fluid as well as serum level of malondialdehyde, while serum superoxide dismutase activity was increased significantly in the treatment group (P < 0.05). In the treatment group, emphysema-like changes were mitigated and CM-Dil-labeled adipose-derived mesenchymal stem cells were capable of homing to the lung tissue of rats with chronic obstructive pulmonary disease and survived. All these findings show that adipose-derived mesenchymal stem cell transplantation can improve lung function of rats with chronic obstructive pulmonary disease, and reduce inflammatory response, which has for certain some therapeutic effects.
