Abstract

No effective treatments have yet been developed for burn-induced neuropathic pain. Platelet-rich plasma (PRP) has been reported to ameliorate various types of inflammation pain. However, the effect of PRP on burn-induced neuropathic pain is unclear. Burn-induced neuropathic pain Sprague-Dawley rat model was confirmed using a mechanical response test 4 weeks after the burn injuries were sustained, following which PRP was injected in the scar area. The rats were divided into four groups (n = 6) as following: Group A, Sham; Group B, Sham + PRP; Group C, Burn; and Group D, Burn + PRP. Four weeks after the PRP injection, the animals were subjected to behavior tests and then sacrificed; specimens were collected for inflammation tests, Masson's trichrome stain and chromosome 10 (PTEN) in the injured skin; and PTEN, phosphorylated mammalian target of rapamycin (p-mTOR), p38, nuclear factor κB (NFκB), chemokine (CC motif) ligand 2 (CCL2), and CCL2 cognate receptor (CCR2) in spinal cord dorsal horns through immunohistochemistry and immunofluorescence staining. : PRP significantly alleviated allodynia in burn-induced neuropathic pain 4 weeks after treatment, and PTEN expression in the skin and spinal cord were significantly increased in group D compared with the group C. p-PTEN, p-mTOR, and CCL2 expression in neuron cells; p-p38 and p-NFκB expression in microglia; and p-JNK and p-NFκB activation in spinal astrocytes decreased significantly in the group D compared with the group C. : PRP is effective in treating burn-induced neuropathic pain and may be used in clinical practice.

摘要

目前尚未开发出有效治疗烧伤后神经病理性疼痛的方法。富血小板血浆(PRP)已被报道可改善各种类型的炎症疼痛。然而,PRP 对烧伤后神经病理性疼痛的影响尚不清楚。

通过在烧伤后 4 周进行机械反应测试,确认建立了烧伤后神经病理性疼痛 Sprague-Dawley 大鼠模型,随后在疤痕区域注射 PRP。将大鼠分为 4 组(n = 6):A 组,假手术;B 组,假手术+PRP;C 组,烧伤;D 组,烧伤+PRP。PRP 注射 4 周后,对动物进行行为测试,然后处死;采集标本进行炎症测试、Masson 三色染色和损伤皮肤中的第 10 号染色体(PTEN);并通过免疫组化和免疫荧光染色检测脊髓背角中的 PTEN、磷酸化哺乳动物雷帕霉素靶蛋白(p-mTOR)、p38、核因子κB(NFκB)、趋化因子(CC 基序)配体 2(CCL2)和 CCL2 同源受体(CCR2)。

结果

PRP 显著缓解烧伤后神经病理性疼痛 4 周后的痛觉过敏,与 C 组相比,D 组皮肤和脊髓中的 PTEN 表达明显增加。神经元细胞中 p-PTEN、p-mTOR 和 CCL2 的表达;小胶质细胞中 p-p38 和 p-NFκB 的表达;以及脊髓星形胶质细胞中 p-JNK 和 p-NFκB 的激活在 D 组明显低于 C 组。

结论

PRP 治疗烧伤后神经病理性疼痛有效,可能用于临床实践。
