experiment,  the  primary  nucleus  pulposus  cells  were  isolated  and  cultured  from  rats,  and  cellular  degeneration  was  induced  using
          50  ng/mL TNF-α. The cells were  divided into blank control group (10%  blank control serum), TNF-α  group (10%  blank control
          serum),  YC-1  group (10%  blank  control  serum+0.2  mmol/L  YC-1),  and  5%,  10%,  15%  drug-containing  serum  group (5%,
          10%, 15% drug-containing serum). After 24 hours of intervention, the nucleus pulposus cells were co-cultured with HUVEC. The
          expressions  of  Collagen  Ⅱ,  matrix  metalloproteinase-3 (MMP-3)  in  nucleus  pulposus  cells  were  detected.  HUVEC  proliferation,
          migration and tube forming ability were detected, and the expression levels of the HIF-1α/VEGF/Ang signal axis and angiogenesis-
          related  proteins (add  MMP-2,  MMP-9)  in  HUVEC  were  detected.  RESULTS  Animal  experiments  had  shown  that  compared  with
          model group, the positive expression of CD31 in the intervertebral disc tissues of rats in each drug group was down-regulated (P<
          0.05),  the  levels  of  inflammatory  factors  and  angiogenesis-related  proteins  were  decreased  significantly (P<0.05),  and  the
          pathological  changes  in  the  intervertebral  disc  were  alleviated.  Cell  experiments  had  shown  that  compared  with TNF-α  group,  the
          expression of Collagen Ⅱ in nucleus pulposus cells of all drug groups was significantly up-regulated (P<0.05), and the expression
          of  MMP-3  was  significantly  down-regulated (P<0.05);  the  proliferation,  migration  and  tubulogenesis  of  HUVEC  were
          significantly  weakened (P<0.05).  The  mRNA  and  protein  expressions  of  HIF-1α,  VEGF,  Ang  2  as  well  as  the  expression  of
          angiogenesis-related  proteins (except  for  the  expression  of  Ang  2  mRNA  and  HIF-1α,  VEGFR2,  Ang  2  protein  in  5%  drug-
          containing  serum  group)  were  significantly  down-regulated (P<0.05).  CONCLUSIONS  ZQGCD  may  inhibit  the  HIF-1α/VEGF/
          Ang  signal  axis  to  weaken  the  angiogenic  ability  of  vascular  endothelial  cells,  improve  pathological  angiogenesis  in  the
          intervertebral disc, and delay the degeneration of the intervertebral disc.
