【摘 要】 目的 檢驗(yàn)陽(yáng)離子脂質(zhì)體包封萬(wàn)古霉素復(fù)合納米羥基磷灰石/ 殼聚糖/ 魔芋葡甘聚糖（nanohydroxyapatite/
chitosan/konjac glucomannan，n-HA/CS/KGM）支架體內(nèi)抗感染及骨修復(fù)活性。 方法 取6 月齡健康新
西蘭大白兔51 只，體重1.5 ～ 3.0 kg，用金黃色葡萄球菌制備慢性感染性雙側(cè)脛骨骨缺損模型。將造模后4 周存活的48
只兔隨機(jī)分為4 組，每組12 只。根據(jù)以下分組方法，分別于雙側(cè)骨缺損處植入相應(yīng)支架。A 組：清創(chuàng)后不作任何處理；B
組：n-HA/CS/KGM 空白支架組；C 組：萬(wàn)古霉素復(fù)合n-HA/CS/KGM 支架組；D 組：萬(wàn)古霉素陽(yáng)離子脂質(zhì)體復(fù)合n-HA/
CS/KGM 支架組。治療后8 周行大體、骨缺損修復(fù)、組織學(xué)觀察以及X 線片、細(xì)菌學(xué)檢查。 結(jié)果 實(shí)驗(yàn)動(dòng)物造模后4 周
X 線片顯示明顯骨質(zhì)缺損、低密度影及軟組織腫脹影，Norden 評(píng)分均 gt; 3 分，為（3.83 ± 0.52）分。治療后8 周大體觀察：C、D 組竇道已愈合，A、B 組仍有竇道；大體觀察病理評(píng)分C、D 組明顯優(yōu)于A、B 組（P  lt; 0.05）。骨缺損修復(fù)觀察：D 組骨缺損已修復(fù)，骨缺損最長(zhǎng)徑顯著優(yōu)于A、B、C 組（P  lt; 0.05）。X 線片檢查：C、D 組可見(jiàn)新骨形成，A、B 組可見(jiàn)骨膜反應(yīng)及髓腔低密度影；Norden 評(píng)分D 組明顯小于A、B、C 組（P  lt; 0.05）。組織學(xué)觀察：HE 染色示C、D 組可見(jiàn)大量骨小梁形成，
纖維增生，未見(jiàn)明顯感染跡象，A、B 組仍可見(jiàn)中性粒細(xì)胞積聚；Smeltzer 評(píng)分C、D 組明顯優(yōu)于A、B 組（P  lt; 0.05）。細(xì)菌
學(xué)檢查：C、D 組陰性率明顯高于A、B 組（P  lt; 0.05）。 結(jié)論 萬(wàn)古霉素陽(yáng)離子脂質(zhì)體復(fù)合n-HA/CS/KGM 支架可很好治
療兔慢性感染性脛骨骨缺損，為臨床上治療慢性感染性骨缺損提供了新思路。
