目的研究表面含硅微弧氧化（micro-arc oxidation，MAO）涂層鎂合金ZK60體外與成骨細胞的生物相容性。方法掃描電鏡觀察表面含硅MAO涂層鎂合金ZK60的表面形貌，并用能譜分析儀檢測涂層元素組成。實驗分為表面含硅MAO涂層鎂合金ZK60組（A組）、無涂層鎂合金ZK60組（B組）、醫用鈦合金組（C組）及空白對照組（D組）。取A、B、C組對應材料按照ISO 10993-12標準（試樣表面積/浸體介質= 1.25 cm2/mL）分別制備材料浸提液并培養小鼠前成骨細胞MC3T3-El，D組采用含10%FBS的α-MEM培養基進行培養。倒置相差顯微鏡觀察細胞形態，MTT法檢測細胞增殖活力，并檢測成骨細胞ALP表達活性。掃描電鏡觀察A、B、C組材料表面細胞黏附形態，檢測涂層表面的蛋白吸附能力，采用DAPI觀察細胞早期黏附情況，鈣黃綠素/乙錠均二聚物1（calcein-AM/ethidium homodimer 1，calcein- AM/ EthD- 1）雙重染色觀察細胞生長狀態。結果掃描電鏡下見表面含硅MAO涂層鎂合金ZK60呈粗糙、多孔表面形態，涂層的主要組成元素為Mg、O和Si。材料浸提液培養后各組細胞輪廓清晰、形態良好，其中A組細胞伸展性更好。培養5 d時，MTT檢測示A組細胞增殖活力明顯高于其他組（P lt; 0.05）。掃描電鏡觀察見A、C組材料表面細胞伸展性良好，優于B組，且A組細胞與材料表面黏附更緊密。A組材料表面蛋白吸附量為（152.7 ± 6.3）μg/mL，明顯高于B、C組的（96.3 ± 3.9）、（96.1 ± 8.7） μg/ mL（P lt; 0.05）；各時間點A組細胞黏附數量均明顯高于B、C組（P lt; 0.05）。calcein-AM/EthD-1雙染觀察見A、C組材料表面細胞生長狀態優于B組。 A、B組ALP表達分別為15.55 ± 0.29和13.75 ± 0.44，明顯高于C、D組的10.43 ± 0.79和10.73 ± 0.47（P lt; 0.05），且A組高于B組（P lt; 0.05）。結論表面含硅MAO涂層鎂合金ZK60可促進成骨細胞增殖、黏附及分化，具有良好生物相容性，是一種較理想的鎂合金表面改性方法。
