          摘   要  目的  探讨胡黄连苷Ⅱ对非小细胞肺癌(NSCLC)恶性进展的影响及机制。方法  将A549细胞分组为对照组,胡黄连苷
          Ⅱ低、中、高浓度组,K6PC-5[鞘氨醇激酶1(SPHK1)激活剂]组,胡黄连苷Ⅱ高剂量+K6PC-5组,检测细胞增殖、迁移、侵袭情况,以
          及细胞中增殖细胞核抗原(PCNA)、基质金属蛋白酶2(MMP-2)、MMP-9、SPHK1、1-磷酸鞘氨醇受体3(S1PR3)及胞外信号调节激
          酶1/2(ERK1/2)蛋白的表达情况。以BALB/c裸鼠为对象,通过皮下接种A549细胞悬液建立NSCLC裸鼠移植瘤模型,并将其分
          为裸鼠-对照组,裸鼠-胡黄连苷Ⅱ低、中、高剂量组,裸鼠-K6PC-5组,裸鼠-胡黄连苷Ⅱ高剂量+K6PC-5组(每组5只),考察胡黄连
          苷Ⅱ对其瘤体质量及体积的影响。结果  与对照组比较,胡黄连苷Ⅱ低、中、高浓度组的细胞OD450值、EdU阳性细胞率、划痕愈合
          率、细胞侵袭数及PCNA、MMP-2、MMP-9、SPHK1、S1PR3、ERK1/2蛋白的相对表达量均显著降低;与裸鼠-对照组比较,裸鼠-胡黄
          连苷Ⅱ低、中、高剂量组裸鼠体内的瘤体质量及体积均显著降低或缩小,上述指标均呈浓度/剂量依赖性变化(P<0.05);K6PC-5组
          细胞和裸鼠-K6PC-5组裸鼠对应指标的变化趋势则相反(P<0.05)。与胡黄连苷Ⅱ高浓度组或裸鼠-胡黄连苷Ⅱ高剂量组比较,胡
          黄连苷Ⅱ高浓度+K6PC-5组细胞和裸鼠-胡黄连苷Ⅱ高剂量+K6PC-5组裸鼠的上述定量指标均显著升高或增大(P<0.05)。结论
          胡黄连苷Ⅱ可能通过抑制SPHK1/1-磷酸鞘氨醇/S1PR3信号通路来抑制NSCLC的恶性进展。

          ABSTRACT    OBJECTIVE  To  investigate  the  effect  and  mechanism  of  picroside  Ⅱ  on  the  malignant  progression  of  non-small
          cell  lung  cancer (NSCLC).  METHODS  A549  cells  were  divided  into  the  control  group,  picroside  Ⅱ  low-,  medium-  and  high-
          concentration  groups,  K6PC-5  [sphingosine  kinase  1 (SPHK1)  activator]  group,  and  picroside  Ⅱ  high-dose+K6PC-5  group.  Cell
          proliferation,  migration  and  invasion  were  detected.  Besides,  the  expression  of  proliferating  cell  nuclear  antigen (PCNA),  matrix
          metalloproteinase-2 (MMP-2),  MMP-9,  SPHK1,  sphingosine-1-phosphate  receptor  3 (S1PR3)  and  extracellular  signal-regulated
          kinase  1/2 (ERK1/2)  protein  in  the  cells  were  also  observed.  BALB/c  nude  mice  were  subcutaneously  inoculated  with A549  cell
          suspension to establish NSCLC xenograft models. Then they were assigned to the nude mouse-control group, nude mouse-picroside
          Ⅱ  low- ,  medium-  and  high-dose  groups,  nude  mouse-K6PC-5  group,  and  nude  mouse-picroside  Ⅱ  high-dose+K6PC-5  group
         (with  5  mice  in  each  group)  to  investigate  the  effect  of  picroside  Ⅱ  on  their  tumor  mass  and  volume.  RESULTS  Compared  with
          the  control  group,  the  OD450  values,  EdU-positive  cell  rates,  scratch  healing  rates,  cell  invasion  number,  and  the  relative
          expression levels of PCNA, MMP-2, MMP-9, SPHK1, S1PR3 and ERK1/2 protein in the low-, medium- and high-concentration
          groups  of  picroside  Ⅱ  were  significantly decreased.  Compared  with  the  nude  mouse-control  group,  the  tumor  mass  and  volume  in
          the nude mouse-low-, medium- and high-dose groups of picroside Ⅱ were significantly decreased or shrunk. The changes of above
                                                              indicators  were  concentration/dose-dependent (P<0.05).  The
