Methods:The decellularized scaffolds prepared by using lyolecithin,DNase and RNase to treat the canine sciatic nerves were compounded with bone marrow derived neural tissue-committed stem cells via microinjection to creat the tissue engineered nerve,and thereby bridge the mouse sciatic nerve gap.
方法:将骨髓神经组织定向干细胞(NTC-SCs)种植于犬坐骨神经脱细胞神经支架,构建组织工程化神经,桥接缺损的大鼠坐骨神经,检测所构建生物化组织工程神经中骨髓NTCSCs的增殖、分化及神经性基因表达,观察该神经移植到体内后的细胞增殖、分化及对神经缺损功能的修复。
补充资料：陈旧性会阴Ⅲ度裂伤修补术
陈旧性会阴Ⅲ度裂伤修补术
会阴Ⅲ度裂伤为会阴裂伤中最严重者，常见于难产手术损伤或胎儿过大。儿头娩出时保护会阴不力所致。即肛提肌、阴道筋膜，肛门括约肌甚至直肠下段均有损伤而撕裂，以致大便失禁及不能完全控制排气。如果修补手术不在产后立即进行者称之为陈旧性会阴Ⅲ度裂伤修补术。术前准备：术前3日少渣饮食，每天用1∶5000高锰酸钾溶液坐浴1～2次，每晚灌肠1次。术前3日口服新霉素等药物控制肠道细菌。手术前晚清洁灌肠，麻醉，骶管麻醉，手术步骤：①认真检查裂伤情况及解剖关系。用两把鼠齿钳暴露裂伤边缘，沿裂伤边缘切开阴道黏膜，见阴道壁与直肠的分界，分离阴道壁与直肠黏膜，并向两侧分离阴道壁，暴露直肠及肛门扩约肌的两侧断端处，剪去直肠裂缘瘢痕组织。②缝合直肠用000可吸收线间断及连续缝合直肠壁，一般不透过直肠黏膜，亦可穿透黏膜，把结打在肠腔内；③缝合肛门括约肌，用鼠齿钳自两侧凹陷处夹取肛门括约肌断端，并向中线靠拢，用丝线作“8”字缝合。此时，肛门周围皮肤即皱缩呈环状。④缝合肛提肌，1号铬肠线间断缝合，⑤修剪阴道黏膜后1号肠线缝合阴道黏膜。⑥缝合皮肤和皮下组织。术后处理同会阴Ⅲ度裂伤。无渣饮食控制大便5天，以利伤口愈合。
