目的 富血小板血漿（platelet-rich plasma，PRP）具有刺激椎間盤細胞增殖、促進細胞外基質合成代謝及抑制纖維環(huán)細胞凋亡等作用。通過觀察自體PRP干預兔早期椎間盤退變，明確其治療效果，為臨床應用提供理論依據。 方法取健康成年新西蘭大白兔45只，體重2.5～3.0 kg，雌雄不限；隨機分為實驗組、對照組、假手術組（n=15）。取實驗組兔耳中央動脈血，采用Landesberg等方法制備PRP，同時對全血及PRP行血小板計數。實驗組及對照組采用纖維環(huán)針刺法建立L4、5及L5、6椎間盤退變模型，造模2周后于L4、5及L5、6椎間隙分別注入100 ?L自體PRP及100 ?L PBS液；假手術組僅分離暴露椎間盤，不作處理。觀察實驗動物造模后一般情況；造模2周及干預1、2周時各組取5只實驗動物行腰椎MRI、HE染色及Ⅱ型膠原免疫組織化學染色觀察，腰椎MRI退變程度分級及Ⅱ型膠原陽性積分吸光度（IA）值檢測。 結果兔PRP中血小板計數約為外周血的4.92倍。實驗動物均存活至實驗完成。造模2周時，與假手術組相比，實驗組和對照組椎間盤信號降低，髓核細胞減少，基質退變，Ⅱ型膠原表達降低。腰椎MRI退變程度分級及Ⅱ型膠原陽性IA值結果顯示，各時間點實驗組、對照組與假手術組相比差異均有統(tǒng)計學意義（P lt; 0.05），干預1、2周時，實驗組MRI退變程度分級顯著低于對照組 （P lt; 0.05），但仍與假手術組有差異（P lt; 0.05）；干預1、2周時，實驗組髓核細胞及軟骨樣基質較對照組增多，基質纖維化程度輕，Ⅱ型膠原表達明顯強于對照組（P lt; 0.05）。 結論椎間盤內注射自體PRP可終止甚至一定程度逆轉兔早期椎間盤退變，可能與PRP含有多種生長因子調控細胞功能、改善組織微環(huán)境、促進組織再生修復有關。
