          摘  要  目的  制备并表征姜黄素纳米胶束(简称“Cur/mPEG-PBLA胶束”),并评价其抗酒精性肝病的体外活性。方法  以聚乙二
          醇-聚天冬氨酸苄酯嵌段共聚物(mPEG-PBLA)为载体,采用透析法制备Cur/mPEG-PBLA胶束;观察其外观和显微形态,检测其粒
          径、多分散性指数、Zeta电位、包封率及载药量,并进行体外释放、pH稳定性、热稳定性、稀释稳定性、储存稳定性、血浆稳定性考察
          和溶血实验。以人肝癌细胞、正常肝细胞为对象,以 Cur 对照品溶液为参照,采用无水乙醇干预建立酒精性肝病细胞模型,评价
          Cur/mPEG-PBLA胶束对酒精性肝病的体外预防和改善作用。结果  所制Cur/mPEG-PBLA胶束显淡黄色乳光,呈圆球形且分布均
          匀,平均粒径约 140 nm,多分散性指数<0.3,Zeta 电位为(-8.15±0.05)mV;包封率及载药量分别为(73.26±3.16)%、(4.87±
          0.42)%。Cur对照品在10 h时的累积释放率接近80%;Cur/mPEG-PBLA胶束在8 h时的累积释放率仅为28.94%,在48 h时的累积
          释放率才达48.25%。Cur/mPEG-PBLA胶束的pH稳定性、热稳定性均优于Cur对照品溶液,稀释稳定性、储存稳定性、血浆稳定性
          均较好,且不会引发溶血现象。Cur对照品溶液和Cur/mPEG-PBLA胶束对2种细胞的酒精性损伤均有不同程度的体外预防和改
          善作用;且作用48 h时,Cur/mPEG-PBLA胶束的上述作用均显著优于同质量浓度的Cur对照品溶液(P<0.05)。结论  Cur/mPEG-
          PBLA胶束可提高Cur的pH稳定性、热稳定性,延缓其释放速度,同时具有更强的体外抗酒精性肝病活性。

          ABSTRACT   OBJECTIVE  To  prepare  and  characterize  curcumin  nanomicelles (hereinafter  referred  to  as  Cur/mPEG-PBLA
          micelles), and to evaluate the in vitro hepatoprotective activity against alcohol liver disease (ALD). METHODS Cur/mPEG-PBLA
          micelles  were  prepared  with  the  dialysis  method  using  methoxy-poly(ethylene  glycol)-poly(β-benzyl-L-aspartate) (mPEG-PLGA)
          as  the  carrier.  The  appearance  and  microscopic  morphology  of  Cur/mPEG-PBLA  micelles  were  observed,  and  particle  size,
          polydispersity  index,  Zeta  potential,  encapsulation  efficiency  and  drug  loading  content  were  all  detected. The  in  vitro  release,  pH
          stability,  thermal  stability,  dilution  stability,  storage  stability,  plasma  stability  tests,  and  hemolysis  experiments  were  all
          performed. The  cell  model  of ALD  was  established  with  anhydrous  ethanol  intervention  using  human  liver  cancer  cells  and  normal
          liver  cells  as  objects,  Cur  reference  solution  as  reference,  to  evaluate  in  vitro  preventive  and  ameliorative  effects  of  Cur/mPEG-
          PBLA  micelles  on ALD.  RESULTS  The  prepared  Cur/mPEG-PBLA  micelles  exhibited  a  pale-yellow  milky  light,  with  a  spherical
          shape  and  uniform  distribution.  The  average  particle  size  was  about  140  nm,  and  the  polydispersity  index  was  less  than  0.3.  Zeta
          potential  was (-8.15±0.05)  mV;  the  encapsulation  efficiency  was (73.26±3.16)%,  and  the  drug  loading  content  was (4.87±
          0.42)%. The cumulative release of Cur reference substance was close to 80% at 10 h; the cumulative release of Cur/mPEG-PBLA
          micelles  at  8  h  was  28.94%  and  only  48.25%  at  48  h.  pH  stability  and  thermal  stability  of  Cur/mPEG-PBLA  micelles  were  better
                                                             than  those  of  Cur  reference  solution;  Cur/mPEG-PBLA
