【摘 要】 目的 總結(jié)臍帶間充質(zhì)干細(xì)胞(umbilical cord mesenchymal stem cells,UCMSCs)移植治療骨折外露性
難愈創(chuàng)面的效果。 方法 2008 年9 月收治1 例45 歲機器軋燙傷致左橈骨遠(yuǎn)1/3 處骨折、伴骨折淺面伸指肌群和皮膚
全層毀損創(chuàng)面患者,給予腹部帶蒂皮瓣修復(fù)。術(shù)后骨折端出現(xiàn)感染并破潰形成竇道,經(jīng)長時間封閉式負(fù)壓吸引、外用生長
因子類藥物加強換藥,創(chuàng)面及骨折仍不愈合。于傷后6 個月,采用注射1 × 106 個/mL UCMSCs 細(xì)胞懸液1 mL 至竇道并
填滿創(chuàng)腔治療,每隔2 ~ 3 d 治療1 次,至創(chuàng)面愈合。 結(jié)果 治療4 次后創(chuàng)面肉芽組織迅速增生填滿竇道并上皮化,12 d
創(chuàng)面愈合。X 線片隨訪示治療后骨折端骨痂開始大量生長、骨折線漸模糊。傷后1 年患者入院行皮瓣修薄術(shù),見局部皮膚
穩(wěn)定無潰破,骨折愈合并重塑。 結(jié)論 UCMSCs 移植改變了骨折外露創(chuàng)面遷延不愈的修復(fù)進程,促進了創(chuàng)面和骨折愈
合,但其有效性及安全性尚需大樣本隨訪觀察。
