摘要:

背景:同种异体骨是临床常用的骨移植材料,但缺乏诱导成骨能力是最大的问题。
目的:评价良性骨肿瘤及瘤样病变刮除或切除后应用同种异体骨复合自体骨髓干细胞修复骨缺损的效果。
方法:65例良性骨肿瘤(包括瘤样病变)患者,根据植骨情况分为2组。复合骨髓干细胞植骨组35例患者根据预计植骨量从每位患者两侧的髂前上棘或髂后上棘抽取红骨髓20-40 mL,经体外分离、纯化、培养扩增骨髓基质干细胞备用,在植骨前将同种异体骨颗粒与骨髓基质干细胞充分混匀。肿瘤刮除或切除后,将混匀的骨髓基质干细胞与同种异体骨颗粒,植入骨缺损区内。单纯植骨组将用生理盐水浸泡半小时的同种异体骨植入骨缺损区内。分别于治疗后1,3,6,12个月进行植骨区X射线检查,比较两组病例同种异体骨颗粒界限模糊、消失的时间,同时观察术后并发症发生情况。
结果与结论:62例患者均获得12个月以上随访。复合骨髓干细胞植骨组移植骨界限模糊时间和消失时间均短于单纯植骨组(P < 0.05)。复合骨髓干细胞植骨组1例出现排异反应,使用免疫抑制剂治疗2周后痊愈,两组病例均未出现感染。结果表明同种异体骨复合自体骨髓干细胞植骨能明显促进骨融合和骨缺损的愈合。

Abstract:

BACKGROUND: Allogenic bone is a clinical commonly used bone graft material, but the osteoinductive capacity is the biggest problem.
OBJECTIVE: To evaluate the effect of allogeneic bone combined with autologous bone marrow stem cells on the repair of bone defects after scraping or resection of benign bone tumors and tumor-like lesions.
METHODS: Sixty-five cases of benign bone tumors (including patients with tumor-like lesions) were divided into two groups according to bone graft. There were 35 cases in the composite bone marrow stem cells for bone graft group, and 20-40 mL red bone marrow were extracted from anterosuperior iliac spine or iliac spine on both sides according to the expected amount of bone graft, then the bone marrow stem cells were isolated, purified, cultured and amplified for standby, and the bone marrow stromal stem cells and allogeneic bone particles were fully blended before bong graft. After tumor scraping or resection, the blended bone marrow stromal stem cells and allogeneic bone particles were implanted into the bone defect region. In the bone graft group, the bone defect was implanted with allogeneic bone soaked with saline for half an hour. X-ray examination was performed at 1, 3, 6 and 12 months after treatment to compare the fuzzy boundary and the time for disappear, and the postoperative complications were observed.  
RESULTS AND CONCLUSION: All the 62 patients were followed-up for more than 12 months. The fuzzy boundary time and disappear time in the composite bone marrow stem cells for bone graft group were shorter than those in the bone graft group (P < 0.05). In the composite bone marrow stem cells for bone graft group, one case appeared rejection and healed after treated with immunosuppressive agents for 2 weeks, and no complication observed in two groups. The results indicate that allogeneic bone composite autologous bone marrow stem cells for bone graft can promote bone fusion and bone defect healing.
