文题释义:
自体外周血干细胞:
骨髓产生大量干细胞,一部分进入到外周血中,称为外周血干细胞,正常情况下,外周血中的干/祖细胞的含量占单个核细胞的很少一部分,但是经动员由骨髓释放到外周血中的造血干细胞数量明显增加,甚至细胞数量可以达到骨髓中的水平,且具备成体干细胞的特点。
自体外周血单个核细胞:是存在于外周血中具有单个核细胞的总称,其中含有诸多干细胞(造血干细胞、血管内皮祖细胞、间充质干细胞、淋巴细胞和单核细胞等),有强大的自我增殖能力,在微环境以及特定条件下可以向心肌细胞、神经细胞、血管内皮细胞等分化的一种细胞。

 

摘要
背景:
近年来神经干细胞、脂肪间充质干细胞、肌源性干细胞、诱导多能干细胞已应用于治疗周围神经损伤,但自体外周血单个核细胞应用于外周神经损伤的治疗鲜有报道。
目的:观察自体外周血单个核细胞治疗高位桡神经离断伤的疗效。
方法:自2011年4月至2015年9月,共收治上臂中段桡神经离断伤12例,术前动员外周血单个核细胞,手术当日提取外周血单个核细胞悬液15 mL,手术探查吻合桡神经,显微镜下行端端外膜缝合法吻合神经,用浸泡5 mL自体外周血单个核细胞悬液的凝胶海绵包裹神经吻合口,剩余10 mL外周血单个核细胞悬液行局部肌肉多点注射,每点注射0.5 mL,缝合深筋膜,常规缝合伤口。术后给予抗生素预防感染48 h,上肢制动4周,指导患者康复锻炼。随访观察腕关节背伸度数、伸腕伸指肌肌力,进行疗效评价。
结果与结论:①术后患者均获随访,随访时间15-36个月,平均17个月;②综合评价:优9例,良2例,可1例,差0例,优良率为92%;③腕关节背伸均能够达到功能需要,拇指背伸、伸指基本满足功能要求;④结果提示,自体外周血单个核细胞移植治疗高位桡神经损伤效果满意。

Abstract:

BACKGROUND: In recent years, neural stem cells, adipose tissue derived mesenchymal stem cells, muscle derived stem cells and induced pluripotent stem cells have been applied in the treatment of peripheral nerve injuries. However, the treatment of peripheral nerve injury by autologous peripheral blood mononuclear cells has rarely been reported.
OBJECTIVE: To investigate the efficacy of autologous peripheral blood mononuclear cells in the treatment of high radial nerve injury. 
METHODS: From April 2011 to September 2015, 12 cases of radial nerve injury in the middle arm were treated. Preoperatively peripheral blood mononuclear cells were mobilized, and then 15 mL of mononuclear cell suspension was prepared on the operation day. Radial nerves scheduled for anastomosis were surgically explored and subjected to end-end anastomosis using outer membrane suturing under microscope. The anastomotic site of the nerve was enveloped with gelatin sponge soaked with 5 mL of autologous peripheral blood mononuclear cell suspension. The remaining 10mL of cell suspension was used for a multi-point injection into the local muscles, 0.5 mL at each point. Thereafter, the deep fascia and the incision were sutured in sequence. Postoperative antibiotics were used to prevent infection for 48 hours, and upper limb immobilization lasted for 4 weeks. Performance of rehabilitation exercise was guided. During the follow-up, wrist dorsal extension and muscle strength of extensor carpi ulnaris and extensor digitorum communis were detected to evaluate the therapeutic efficacy.
RESULTS AND CONCLUSION: All the patients were followed up for 15 to 36 months, with an average of 17 months. Efficacy was excellent in 9 cases, good in 2 cases, fair in 1 case and poor in 0 case. The excellent and good rate was 92%. The wrist dorsal extension could achieve the functional needs, and the thumb dorsal extension and finger extension basically met the functional requirements. It is suggested that autologous peripheral blood mononuclear cell transplantation can achieve good outcomes in the treatment of high radial nerve injury.
