          摘  要  目的  探究骨碎补总黄酮(TFRD)调控Notch1/发状分裂相关增强子1(Hes1)信号轴对脂多糖(LPS)诱导的软骨细胞自噬
          及凋亡的影响。方法  采用5 μg/mL LPS处理人软骨细胞系C28/I2细胞构建体外炎症损伤模型,将细胞分为正常对照组、模型组、
          TFRD 组(200 μg/mL)、TFRD+过氧化物氧化还原酶 1(Prdx1)小干扰 RNA(si-Prdx1)组和 TFRD+si-Prdx1 阴性对照(si-NC)组,每
          组设6个复孔。细胞以si-Prdx1或si-NC转染24 h、TFRD预处理2 h,再以LPS处理,总计培养48 h。检测细胞凋亡率、凋亡细胞占
          比、单丹磺酰尸胺(MDC)荧光强度和基质金属蛋白酶 13(MMP-13)、含Ⅰ型血小板结合蛋白基序的解聚蛋白样金属蛋白酶 5
         (ADAMTS5)、软骨寡聚基质蛋白(COMP)含量以及X连锁凋亡抑制蛋白(XIAP)、多腺苷二磷酸核糖聚合1(PARP1)、Beclin-1、微
          管相关蛋白 1 轻链 3Ⅱ/Ⅰ(LC3-Ⅱ/Ⅰ)、PTEN 诱导激酶 1(PINK1)、Notch1、Hes1、Prdx1 蛋白表达情况。结果  与模型组比较,
          TFRD组细胞凋亡率、凋亡细胞占比和MMP-13、ADAMTS5含量以及PARP1蛋白表达水平均显著降低,MDC荧光强度、COMP含
          量和 XIAP、Beclin-1、LC3-Ⅱ/Ⅰ、PINK1、Notch1、Hes1、Prdx1 蛋白表达水平均升高(P<0.05)。与 TFRD+si-NC 组比较,TFRD+si-
          Prdx1组细胞中除Notch1、Hes1以外上述指标的变化均被显著逆转(P<0.05)。结论  TFRD可能通过激活Notch1/Hes1信号轴上
          调下游靶分子Prdx1的表达,进而抑制LPS诱导的软骨细胞凋亡、促进其保护性自噬,从而改善软骨代谢稳态。

          Regulation  of  Notch1/Hes1  signaling  axis  by  total  flavonoids  of  Drynariae  Rhizoma  for  promoting

          ABSTRACT   OBJECTIVE  To  investigate  the  effects  of  total  flavonoids  of  Drynariae  Rhizoma (TFRD)  on  autophagy  and
          apoptosis in LPS-induced chondrocytes via the regulation of the Notch1/hairy and enhancer of split 1 (Notch1/Hes1) signaling axis.
          METHODS  Human  chondrocyte  cell  line  C28/I2  cells  were  cultured  with  5  μg/mL  LPS  to  establish  in  vitro  inflammatory  injury
          model.  The  cells  were  separated  into  normal  control  group,  model  group,  TFRD  group (200  μg/mL),  TFRD+peroxiredoxin  1
         (Prdx1)  small  interfering  RNA (si-Prdx1)  group  and  TFRD+si-Prdx1  negative  control (si-NC)  group,  with  6  replicate  wells  in
          each  group.  Cells  were  transfected  with  si-Prdx1  or  si-NC  for  24  hours,  pretreated  with  TFRD  for  2  hours,  and  then  exposed  to
          LPS,  with  a  total  culture  duration  of  48  hours. Apoptotic  rate,  the  proportion  of  apoptotic  cells,  monodansylcadaverine (MDC)
          fluorescence intensity,  as  well  as  the  contents  of  matrix metalloproteinase-13 (MMP-13),  a  disintegrin and  metalloproteinase  with
          thrombospondin motifs 5 (ADAMTS5), and cartilage oligomeric matrix protein (COMP) were measured. Additionally, the protein
          expression  levels  of  X-linked  inhibitor  of  apoptosis  protein (XIAP),  poly(ADP-ribose)  polymerase  1 (PARP1),  Beclin-1,
          microtubule-associated protein 1 light chain 3 Ⅱ/Ⅰ (LC3-Ⅱ/Ⅰ), PTEN-induced putative kinase 1 (PINK1), Notch1, Hes1, and
          Prdx1 were assessed. RESULTS Compared with model group, the apoptotic rate, the proportion of apoptotic cells, the contents of
                                                             MMP-13  and  ADAMTS5  as  well  as  protein  expressions  of
