Evidence suggests that some systemic and local factors, including cytokines and growth factors in patients with traumatic brain injury (TBI), can play an essential role in accelerating fracture healing. The purpose of this study was to evaluate serum levels of some inflammatory cytokines and growth factors in patients with fracture and TBI as well as healthy subjects. In this study, a total number of 30 patients with a femoral fracture, 30 cases with TBI, 30 patients with TBI and a femoral fracture (fracture + TBI group), and 30 healthy subjects were recruited. The Glasgow Coma Scale (GCS) scores were also determined upon their admission. Then, the serum levels of fibroblast growth factor 2 (FGF-2), transforming growth factor-beta (TGF-β), platelet-derived growth factor (PDGF), bone morphogenetic protein 2 (BMP-2), insulin-like growth factor 1 (IGF-1), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6) were measured via enzyme-linked immunosorbent assay (ELISA) technique, 12 h and 4 weeks after injury and hospital admission. The study results demonstrated that the serum levels of BMP-2, FGF-2, IL-1β, and PDGF in the femoral fracture + TBI group increased significantly over 12 h and after 4 weeks compared with other groups, but the serum levels of IGF-I, IL-6, and TGF-β in this group increased in a significant manner at 12 h compared with other studied groups. The findings also showed that the time to union of a femoral fracture was shorter in the fracture + TBI group than in cases with a femoral fracture alone (p = 0.03). Accordingly, it seems that elevated serum levels of BMP-2, PDGF, FGF-2, and IL-1β may be associated with healing acceleration in fracture + TBI patients. However, further studies are needed to confirm this claim.

外伤性脑损伤与加速骨折愈合之间的关联:生长因子和细胞因子影响的研究。

有证据表明,一些全身和局部因素,包括创伤性脑损伤 (TBI) 患者的细胞因子和生长因子,可以在加速骨折愈合方面发挥重要作用。本研究的目的是评估骨折和 TBI 患者以及健康受试者的某些炎性细胞因子和生长因子的血清水平。本研究共招募股骨骨折患者30例,TBI患者30例,TBI合并股骨骨折患者30例(骨折+TBI组),健康受试者30例。格拉斯哥昏迷量表 (GCS) 分数也在他们入院时确定。然后,血清成纤维细胞生长因子2(FGF-2)、转化生长因子-β(TGF-β)、血小板衍生生长因子(PDGF)、骨形态发生蛋白2(BMP-2)、胰岛素样生长因子 1 (IGF-1)、白细胞介素 1 β (IL-1β) 和白细胞介素 6 (IL-6) 通过酶联免疫吸附试验 (ELISA) 技术,12 小时和 4 周后测量受伤和入院。研究结果表明,与其他组相比,股骨骨折+TBI组12 h及4周后血清BMP-2、FGF-2、IL-1β、PDGF水平显着升高,但IGF血清水平显着升高。与其他研究组相比,该组中的 -I、IL-6 和 TGF-β 在 12 小时时显着增加。研究结果还表明,骨折 + TBI 组股骨骨折愈合的时间比单独股骨骨折的病例短。受伤入院后 12 小时和 4 周。研究结果表明,与其他组相比,股骨骨折+TBI组12 h及4周后血清BMP-2、FGF-2、IL-1β、PDGF水平显着升高,但IGF血清水平显着升高。与其他研究组相比,该组中的 -I、IL-6 和 TGF-β 在 12 小时时显着增加。研究结果还表明,骨折 + TBI 组股骨骨折愈合的时间比单独股骨骨折的病例短。受伤入院后 12 小时和 4 周。研究结果表明,与其他组相比,股骨骨折+TBI组12 h及4周后血清BMP-2、FGF-2、IL-1β、PDGF水平显着升高,但IGF血清水平显着升高。与其他研究组相比,该组中的 -I、IL-6 和 TGF-β 在 12 小时时显着增加。研究结果还表明,骨折 + TBI 组股骨骨折愈合的时间比单独股骨骨折的病例短。与其他研究组相比,该组的 TGF-β 在 12 小时时显着增加。研究结果还表明,骨折 + TBI 组股骨骨折愈合的时间比单独股骨骨折的病例短。与其他研究组相比,该组的 TGF-β 在 12 小时时显着增加。研究结果还表明,骨折 + TBI 组股骨骨折愈合的时间比单独股骨骨折的病例短。p  = 0.03)。因此,似乎 BMP-2、PDGF、FGF-2 和 IL-1β 的血清水平升高可能与骨折 + TBI 患者的愈合加速有关。然而,需要进一步的研究来证实这一说法。
