摘要:

背景:临床上对于股骨头坏死病理机制尚不完全知晓,大剂量使用糖皮质激素容易引起股骨头坏死。
目的:观察骨髓间充质干细胞联合茶黄素在大鼠激素性股骨头坏死中的临床治疗效果。
方法:体外分离培养大鼠骨髓间充质干细胞,将其复合在明胶海绵上。实验分4组,骨髓间充质干细胞联合茶黄素组采用液氮冷冻法建立激素性股骨头坏死鼠模型,并移植复合了骨髓间充质干细胞的明胶海绵,每天进行250 mg茶黄素灌服,设模型对照组,单纯减压组和细胞移植组作对照。
结果与结论:造模后4周,4组大鼠股骨头标本外形表现为圆形,关节软骨呈现为苍白色,关节软骨开始出现剥脱现象。造模后4周,模型对照组关节软骨剥脱加重,部分股骨头标本出现塌陷;骨髓间充质干细胞联合茶黄素组股骨头标本呈现出圆形,且为苍白色。造模后8周,模型对照组坏死区增加;单纯减压组出现成骨细胞,且存在纤维性骨痂形成;细胞移植组能够见到少量空骨陷窝,髓腔形态不规则;骨髓间充质干细胞联合茶黄素组出现大量新生骨形成,且髓内脂肪细胞规则。骨髓间充质干细胞联合茶黄素组造模后4,8周空骨陷窝阳性数显著少于其他3组(P < 0.05)。结果证实,激素性股骨头坏死采用骨髓间充质干细胞基础上联合茶黄素治疗效果理想。

Abstract:

BACKGROUND: Pathological mechanism of femoral head necrosis is not fully known, and high-dose corticosteroids are prone to induce femoral head necrosis.

OBJECTIVE: To investigate the clinical effect of bone marrow mesenchymal stem cells combined with theaflavin on steroid-induced avascular necrosis of femoral head in rats.

METHODS: Rat bone marrow mesenchymal stem cells were isolated and cultured in vitro and compounded onto gelatin sponge, and then, divided into four groups: model group, decompression group, cell transplantation group and combined group. Models of steroid-induced avascular necrosis of femoral head were established using liquid nitrogen method. In the combined group, gelatin sponge carrying bone marrow mesenchymal stem cells was transplanted and 250 mg theaflavin was given daily after modeling.

RESULTS AND CONCLUSION: At 4 weeks after modeling, the femoral head samples in the four groups were round with exfoliation of articular cartilage that was pale in color. Then, the exfoliation of articular cartilage was aggravated in the model group, and some specimens appeared to collapse; the femoral head specimens in the combined group were round and pale. Until the 8th week after modeling, bone necrosis was increased in the model group; osteoblasts were found in the decompression group with fibrous callus formation; a few of empty bone lacunae appeared with irregular medullary cavity in the cell transplantation group; a large amount of new bone tissues formed in the combined group, and intramedullary adiocytes were in regular array. At 4 and 8 weeks after modeling, the number of empty bone lacunae was significantly lower in the combined group than the other groups (P < 0.05). These findings indicate that bone marrow mesenchymal stem cells combined with theaflavin is an ideal therapy for steroid-induced avascular necrosis of femoral head.
