盐酸青藤碱对家兔脊柱压缩性骨折愈合的影响

摘要

目的 研究盐酸青藤碱夹脊穴注射治疗去势家兔L1-L5节段脊柱压缩性骨折(Compression fracture of spine,VCF)的机制.方法 家兔48只,采用随机数字表编号后随机分为空白对照组、模型组和青藤碱组(SIN组),除空白对照组外,其它2组均建立去势后L1-L5节段VCF模型.成模后SIN组于L1-L5节段脊柱两侧“夹脊穴”注射盐酸青藤碱,模型组和空白对照组注射等体积生理盐对照,3组均治疗4周.家兔骨折椎体骨生长分化因子2 (Growth differentiation factor2,GDF2)、血管内皮生长因子(Vascular endothelial growth factor,VEGF)及VEGF-mRNA表达采用免疫组化染色法测定;一氧化氮(Nitric oxide,NO)、超氧化物歧化酶(Superoxide dismutase,SOD)活性和骨保护素(OPG)采用ELISA法检测;免疫荧光法测定脊柱椎间盘二聚糖、图像分析法测L1-L5节段脊柱骨密度;ELISA法检测脊柱椎间盘炎性因子白细胞介素1β(IL-1β)、IL-6β、IL-17β.结果 与模型组比,SIN组L1-L5节段脊柱GDF2、VEGF和VEGFmRNA均高表达、且脊柱骨密度增强(P＜0.05);椎间盘二聚糖增多,IL-1β、IL-6β、IL-17β降低(P＜0.05);静脉血NO降低、OPG、SOD升高(P＜0.05),差异均有统计学意义.结论 盐酸青藤碱“夹脊穴”注射可促进家兔L1-L5节段VCF愈合.%To study the mechanism of injection of sinomenine (Sinomenine,SIN)into Jiaji point in the treatment of L1-L5 segment Compression of fracture spine (VCF) in rabbits.Methods:54 rabbits were randomly divided into blank control group,model group and sinomenine group (group SIN)by the random number table.All the 2 groups established L1-L5 segment VCF model except the blank control group.After molding,the SIN group was injected SIN at both sides of the L1-L5 section of the vertebral column,the model group and the blank control group were injected the same volume of physiological saline as comparison.The 3 groups were treated for 4 weeks.Fracture of vertebral bone growth differentiation factor 2 (Growth differentiation,FACTOR2,GDF2),vascular endothelial growth factor (Vascular endothelial,growth factor,VEGF) and the expression of VEGF-mRNA were determined by immunohistochemical staining method;in venous blood,activities of nitric oxide (Nitric oxide NO),super oxide dissuade (Super oxide dims,unties,SOD) and bone protection Su (OPG) were detected by ELISA;immunofluorescence was used to measure two chitosan,image analysis method was used to detect spinal bone density in L1-L5 segment,the ELISA was used to detect inflammatory factor interleukin 1 beta (IL-1 beta),IL-6 beta,beta IL-17 in the spinal disc.Results:compared with the model group,in the SIN group,VEGF,VEGFmRNA and GDF2 in L1-L5 segment of spine were highly expressed,and the bone density increased (P＜0.05);two chitosan in intervertebral disc increased,IL-1beta,IL-6 beta,IL-17 beta,(P＜ 0.05);NO in venous blood decreased OPG,SOD increased (P＜0.05),the differences were statistically significant.Conclusion:injection of SIN into Jiaji can promote the healing of VCF in L1-L5 segment in rabbits.
