1、西部医学2014年8月第26卷第8期MedJWestChina,August2014,Vo1.26,No.8锁定髓内钉和接骨板治疗股骨干骨折转化生长因子的表达变化缪杰,甘霈(上海市杨浦区安图医院,上海200093)【摘要】目的比较锁定髓内钉和接骨板内固定治疗股骨干骨折术后,患者血清TGF-~3蛋白的表达变化。方法随机选择锁定髓内钉和接骨板内固定治疗股骨颈骨折的病人,在术后1、7、14、60d四个时间点采集血标本,以健康体检者血标本作为对照组,用酶联免疫吸附测定法(Enzyme—linkedimmunosorbentassay,
2、ELISA)检测血清中TGF—Bl的表达差异。结果术后1天,髓内钉组、接骨板组的血清中TGF—B蛋白含量有所增高,但与正常组的差异均不显著;术后7天,髓内钉组、接骨板组的TGF—B蛋白含量明显高于正常组;术后14天,髓内钉组、接骨板组的TGF-O蛋白含量达到最高,分别与正常组之间存在显著差异(均P<0.05)。术后6O天,髓内钉组、接骨板组的TGF-~I蛋白含量明显下降,接近正常。髓内钉组和接骨板组的血清TGF-f~蛋白含量在4个不同时间点均无显著差异(均P>0.05)。对于髓内钉组,术后14天的TGF-t3血清含量显著高于术
3、后1天(PO.05)。结论髓内钉和接骨板内固定治疗股骨干骨折,两组患者血清TGF-I~的表达无明显差异,但是均明显高于正常人,说明两种内固定治疗均与TGF—B的分泌有关。【关键词】股骨干;骨折;内固定;转化生子因子一8【中图分类号】R687.4【文献标志码】Adoi:10.3969/j.issn.1672—3511.2014.08.020TheserumTGF-p,inp
