    • 摘要: 关节软骨缺损的再生修复是现代骨科临床面临的巨大挑战之一.由于软骨组织的无血管性质,其再生或修复能力有限,因此需要适当的材料系统,在物理、机械、组织学和生物学方面重新调整天然软骨组织的功能,促进软骨再生.目前包括基因治疗在内的组织工程技术正在成为软骨治疗的关键方法之一,并且为许多软骨创伤和疾病的治疗带来了新的曙光和更好的结果.本文综述和总结了组织工程技术在治疗关节软骨缺损方面的研究进展.

    • 摘要: BACKGROUND: Particulated juvenile cartilage allograft is simple and easy to obtain, and relevant clinical studies are underway in the USA. However, how the transplanted juvenile cartilage fragments exert biological effects through biochemical mechanisms and genetic signal transduction is still unclear. There is as yet no report on this technology in China. OBJECTIVE: To explore the feasibility of articular cartilage defects repaired with particulated juvenile cartilage allograft. METHODS: The cartilage fragments were obtained from juvenile Pitman-Moore strains (provided by the Laboratory Animal Center of the Army Medical University in China) and cultured in vitro. Brdu immunofluorescence assay was performed at 1, 3, and 7 days of culture. The particulated juvenile cartilage allograft/fibrin gel composites were subcutaneously transplanted into the SCID rats (provided by the Laboratory Animal Center of the Army Medical University). The specimens were taken for hematoxylin-eosin staining, safranin O staining and immunohistochemistry after 1 month. Cartilage defects of 8 mm in diameter were made in the knee joint of 10 adult Pitman-Moore strains (Laboratory Animal Center of the Army Medical University), and were randomized into two groups, which were then transplanted with the particulated juvenile cartilage allograft/fibrin gel composites (experimental group) or nothing (control group). The specimens were taken for hematoxylin-eosin staining, safranin O fast green staining, toluidine blue and immunohistochemistry at 3 months after transplantation. RESULTS AND CONCLUSION: Little Brdu incorporation was detected in juvenile cartilage fragments at 1 day of culture, some Brdu incorporation was defected at 3 days of culture. At 7 days of culture, a progressive increase in the Brdu signal was detected in chondrocytes within the cultured cartilage fragments, which seemed to localize along the tissue edge. At 1 month after subcutaneous transplantation, the particulated juvenile cartilage allograft still survived and were surrounded by few proliferative chondrocytes. There was no obvious tissue repair in the control group at 3 months after transplantation. In the experimental group, there was obvious tissue repair, the color of the newly formed tissues was similar to the normal cartilage tissue, which integrated well with the surrounding normal cartilage tissue, and the cells distributed evenly. These results imply that particulated juvenile cartilage allograft can achieve good results in repairing articular cartilage defects.%背景:同种异体幼年软骨微粒制备简单, 获取容易, 该技术在美国已经进入临床研究阶段, 但临床上还处于"黑箱"操作阶段, 对于移植的幼年软骨微粒是如何通过生物化学机制和基因信号转导发挥生物学效应, 目前还不清楚.目前, 中国还没有相关技术的报道.目的:探索同种异体幼年软骨微粒移植修复关节软骨缺损的可行性.方法:从幼年贵州小香猪 (陆军军医大学实验动物中心提供) 膝关节获取同种异体幼年软骨微粒, 体外培养1, 3, 7 d进行Brdu免疫荧光检测.将同种异体幼年软骨微粒/纤维蛋白凝胶复合物移植于SCID大鼠 (陆军军医大学实验动物中心提供) 皮下, 1个月后取材, 进行苏木精-伊红染色、番红染色、免疫组织化学检测.在10只成年贵州小香猪 (陆军军医大学实验动物中心提供) 膝关节髌骨面制作直径8 mm的软骨缺损, 随机分2组干预, 实验组软骨缺损处移植同种异体幼年软骨微粒/纤维蛋白凝胶复合物, 空白组不移植任何材料, 3个月后取材, 对修复组织进行苏木精-伊红、番红-固绿、甲苯胺蓝、免疫组织化学检测.结果与结论: (1) 在同种异体幼年软骨微粒的体外培养中, 第1天见到极少的软骨细胞脱落与增殖;第3天可见少量的软骨细胞脱落与增殖;第7天见到有明显的细胞脱落与增殖, 且增殖的细胞分布在切缘周围; (2) 皮下移植1个月后, 移植的同种异体幼年软骨微粒仍然存活且周围有少量的软骨细胞增殖; (3) 软骨缺损修复3个月后, 空白组未见明显修复组织;实验组可见明显的修复组织, 新生的软骨组织颜色与正常软骨组织颜色相似, 且与周围正常软骨组织界面整合良好, 细胞分布较均匀; (4) 结果表明, 同种异体幼年软骨微粒修复关节软骨缺损可取得良好的效果.

    • 摘要: Objective To systematically review the efficacy of microfracture versus autologous chondrocyte implantation for treatment of cartilage defects. Methods Databases including PubMed,EMBASE,the Cochrane library (Issue 5,2017),CBM,CNKI and Wanfang data were electronically searched to collect randomized controlled trials (RCTs)about microfracture versus autologous chondrocyte implantation for treatment of cartilage defects from inception to May 2017. Two reviewers independently screened literature,extracted data and assessed the risk of bias of included studies.Then,meta-analysis was performed using RevMan 5.3 software.Results A total of 7 RCTs involing 555 patients were included.The results of meta-analysis showed that KOOS scores at final follow-up in the microfracture group is less than that of autologous chondrocyte implantation group with significant difference(MD=-4.23,95%CI -8.39~-0.06,P=0.05). There were no significant difference between both groups in Tegner scores at final follow-up(MD=-0.13,95% CI=-0.82~0.56,P=0.72),Lysholm scores at final follow-up(MD=-7.21,95% CI-20.19~5.77,P=0.28)and available scores at 2-years follow-up(SMD=-0.50,95%CI-1.05~0.05,P=0.08). Conclusion These findings demonstrate that microfracture result in same outcome with autologous chondrocyte implantation. However,whether microfracture owns a same long-term outcome with autologous chondrocyte implantation in general needs more research.%目的 系统评价微骨折术与自体软骨细胞移植术治疗膝关节软骨缺损的有效性.方法 计算机检索电子数据库PubMed、EMBASE、Cochrane图书馆(2017年第5期)、CBM、中国知网、万方数据库,搜集微骨折术与自体软骨细胞移植术治疗膝关节软骨缺损临床疗效比较的随机对照试验,检索时间均为自建库至2017年5月.由2位研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后,运用RevMan5.3软件进行Meta分析.结果 共纳入7篇随机对照试验,555例患者.Meta分析结果显示:在最终比较随访的膝关节运动评分(Tegner)(均数差-0.13, 95%可信区间-0.82~0.56,P=0.72),Lysholm评分(均数差-7.21,95%可信区间-20.19~5.77,P=0.28),膝关节损伤和骨关节炎评分(均数差-4.23,95%可信区间-8.39~-0.06,P=0.05)和2年随访的各项评分(标准化均数差-0.50, 95%可信区间-1.05~0.05,P=0.08)的对比中,自体软骨移植术仅在膝关节损伤和骨关节炎评分(KOOS)上优于微骨折术,且差异有统计学意义.结论 微骨折术与自体软骨移植术疗效相当,患者术后在关节活动、疼痛、稳定性方面无明显差异.但是否在更加长的时间跨度下仍有相同的疗效需要更多长时间随访的临床研究来支持.

    • 摘要: 背景:文献报道将低强度脉冲超声联合关节腔内注射玻璃酸钠运用于家兔关节软骨缺损修复中效果理想,能促进缺损部位愈合,但是该结论尚未得到进一步证实.目的:进一步验证低强度脉冲超声联合关节腔内注射玻璃钠在家兔关节软骨缺损中的修复效果.方法:60只家兔采用4 mL/kg浓度为20%乌拉坦溶液注射麻醉,在股骨踝部作直径为3 mm、深为3 mm的关节软骨缺损模型,根据处理方法分为模型对照组、玻璃酸钠组和观察组.模型对照组建模成功后不采取任何措施处理,玻璃酸钠组关节腔内注射玻璃酸钠修复,观察组在玻璃酸钠组基础上联合低强度脉冲超声修复.大体观察关节兔软骨缺损部位的形态;比较3组家兔修复后苏木精-伊红染色、番红O染色及Wakitani组织学评分.结果与结论:①大体观察:模型对照组修复5周后缺损直径缩小,表面不平整且低于周围组织;玻璃酸钠组修复5后缺损部位与正常软骨组织边界清晰;观察组修复5周后缺损部位完全修复;②观察组家兔修复后2,5周Wakitani组织学评分,低于玻璃酸钠组和模型对照组(P<0.05);③观察组修复5周缺损部位细胞排列整齐;玻璃酸钠组修复5周后可见少许软骨区大量软骨样细胞;模型对照组修复后2,5周可见毛细心血管分布,排列不均匀;④观察组修复5周后缺损部位形态与正常软骨相似;玻璃酸钠组修复5周后深层蛋白多糖及软骨陷窝存在明显着色;模型对照组修复2,5周后深层染色偏白;⑤结果提示:低强度脉冲超声联合关节腔内注射玻璃钠在家兔关节软骨缺损中能取得理想修复效果.%BACKGROUND: As reported, the use of low-intensity pulsed ultrasound combined with intra-articular injection of sodium hyaluronate in rabbit articular cartilage defect repair is ideal, which can promote the healing of defect site. However, the conclusion has not been further confirmed.OBJECTIVE: To investigate the effect of low-intensity pulsed ultrasound combined with intra-articular injection of sodium hyaluronate in repairing articular cartilage defects in rabbits.METHODS: Sixty rabbits were anesthetized using 20% urethane solution injection at a dose of 4mL/kg, and a model of articular cartilage defect (3 mm in diameter and 3 mm in depth) was made on the femoral ankle of each rabbit. Then, there were three groups in this study: model group with no intervention, sodium hyaluronate group with intra-articular injection of sodium hyaluronate, and observation group with intra-articular injection of sodium hyaluronate combined with low-intensity pulsed ultrasound. Gross observation, hematoxylin-eosin staining, safranin O staining and Wakitani scores were compared among groups after repair.RESULTS AND CONCLUSION: (1) At 5 weeks after repair, in the model group, the defect size was reduced with uneven surface that was lower than the surrounding tissues; in the sodium hyaluronate group, there was a clear boundary between the defect and surrounding cartilage tissues; in the observation group, the defect was completely repaired. (2) After 2 and 5 weeks, the Wakitani scores in the observation group were significantly lower than those in the other two groups (P < 0.05). (3) After 5 weeks, in the observation group, the cells around the defect site arranged regularly, and in the sodium hyaluronate group, there were a large amount of cartilage-like cells in few cartilage regions. In the model group, there were irregularly arranged capillary blood vessels after 2 and 5 weeks. (4) After 5 weeks of repair, cartilage tissues with normal structure were found in the defect site in the observation group, and deeply stained proteoglycan and cartilage lacunae were observed in the sodium hyaluronate group, while in the model group, the deep layer stained white was observed at 2 and 5 weeks after repair. To conclude, low-intensity pulsed ultrasound combined with intra-articular injection of sodium hyaluronate can achieve the ideal repair effect on rabbit articular cartilage defects.
