文题释义:
骨肿瘤:
是发生于骨骼或其附属组织的肿瘤。有良性,恶性之分,良性骨肿瘤易根治,预后良好,恶性骨肿瘤发展迅速,预后不佳,死亡率高。恶性骨肿瘤分为原发性和继发性。从体内其他组织或器官的恶性肿瘤经血液循环、淋巴系统转移至骨骼为继发性恶性骨肿瘤。还有一类病损称瘤样病变,肿瘤样病变的组织不具有肿瘤细胞形态的特点,但其生态和行为都具有肿瘤的破坏性,一般较局限,易根治。
骨髓基质细胞:成体骨髓中的一类多能干细胞。具有分化成骨细胞、软骨细胞、脂肪细胞和其他几种结缔组织细胞(如腱细胞)的潜能,亦可转分化成心肌细胞、骨骼肌细胞。

 

摘要
背景:
骨髓基质干细胞具有较强的成骨潜能,属于当前组织工程中最为理想的种子细胞。但是,临床上未见将骨髓基质干细胞植入良性骨肿瘤和瘤样病变的研究。
目的:探讨体内灌注诱导骨髓基质干细胞方法,研究骨髓基质干细胞在良性骨肿瘤和瘤样病变患者中的临床治疗效果。
方法:将65例良性骨肿瘤和瘤样病变患者根据治疗措施不同分为单纯植骨组(n=30)和骨髓基质干细胞组(n=35)。单纯植骨组采用生理盐水混合同种异体骨进行30 min浸泡,并植入骨缺损部位。骨髓基质干细胞组根据植骨量从每一位患者身上抽取20-40 mL骨髓,分化、纯化,培养获得骨髓基质干细胞,经过体内灌注方法诱导工程骨,并植入骨缺损部位。
结果与结论:①在倒置相差显微镜下,灌注的骨髓细胞悬液中细胞为圆球形,但是细胞大小不一。细胞灌注最初培养皿造血细胞较多。随着培养时间的延长,可见分布在贴壁梭形细胞及悬浮红细胞,细胞多为圆形、三角形;②两组患者治疗后均进行1-12个月随访,患者术后均为甲级愈合。骨髓基质干细胞组患者感染率、愈合时间显著低于单纯植骨组;③结果提示体内灌注诱导骨髓基质干细胞构建组织工程骨效果理想,能促进血供的重建,将骨髓基质干细胞构建组织工程骨运用于良性骨肿瘤和瘤样病变中能够促进骨融合和骨缺损愈合,具有较高的临床应用价值。

Abstract:

BACKGROUND: Bone marrow stromal stem cells have a strong osteogenic potential, which are currently the most ideal seed cells for tissue engineering. However, there is no clinical report on the treatment of benign bone tumors and tumor-like lesions using bone marrow stromal stem cell transplantation.
OBJECTIVE: To investigate the in vivo perfusion method of inducing bone marrow stromal stem cells, and the clinical effects of bone marrow stromal stem cells on benign bone tumors and tumor-like lesions.
METHODS: Sixty-five cases of benign bone tumors and tumor-like lesions were divided into three groups according to the different treatments: bone graft group (n=30) and bone marrow stromal stem cells group (n=35). In the bone graft group, allogeneic bone was soaked in normal saline for 30 minutes, and then implanted into the bone defect site. In the bone marrow stromal stem cells group, 20-40 mL of bone marrow from each patient was extracted to isolate, purify and culture bone marrow stromal stem cells that were then perfused into the bone defect site.
RESULTS AND CONCLUSION: Under the inverted phase contrast microscope, the perfused cells appeared as a spherical shape, with different sizes. Initially, there were more hematopoietic cells in the perfusion cell culture. With the extension of the culture time, adherent spindle cells and suspended red blood cells appeared, which were mostly round and triangular. All the patients were followed up for 1-12 months and healed well after surgery. Compared with the bone graft group, infection rate and healing time were both lower in the bone marrow stromal cell group. To conclude, in vivo perfusion of bone marrow stromal stem cells used for construction of tissue-engineered bone promotes blood supply reconstruction and bone healing in patients with benign bone tumors and tumor-like lesions, which is of high clinical values.
