          摘   要  目的  探究二氢色原酮拼接多环吡咯螺环氧化吲哚类化合物3m抗皮肤鳞状细胞癌的作用及机制。方法  以人皮肤鳞状
          细胞癌 A431、Colo-16 细胞为研究对象,采用 CCK-8 法检测不同浓度(5、10、20、40、80 μmol/L)3m 作用 24、48、72 h 后对 A431、
          Colo-16 细胞增殖的影响,并计算培养 48 h 时的半数抑制浓度(IC50 )。将 A431、Colo-16 细胞分别分为对照组和 3m 低、高浓度组
         (15、30 μmol/L),加入相应药物或培养基培养48 h后,采用倒置显微镜观察细胞形态变化,检测细胞克隆形成率、迁移率、侵袭数、
          细胞周期分布和凋亡率,检测细胞中 Janus 激酶 2/信号转导及转录激活因子 3(JAK2/STAT3)信号通路相关蛋白[JAK2、STAT3、B
          细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)]磷酸化或表达水平及其mRNA的表达水平。结果  不同浓度3m作用24、48、72 h后
          均能显著抑制A431、Colo-16细胞增殖(P<0.01),48 h时的IC50分别为20.36、23.72 μmol/L。作用48 h后,与对照组比较,3m低、高
          浓度组A431、Colo-16细胞排列稀疏、连接松散;克隆形成率、迁移率、侵袭数,细胞中JAK2、STAT3、Bcl-2 mRNA表达水平,JAK2、
          STAT3蛋白磷酸化水平和Bcl-2蛋白表达水平均显著降低/减少(P<0.01);细胞周期G2期占比、凋亡率、Bax蛋白和mRNA表达水
          平均显著升高(P<0.01);上述作用均呈剂量依赖性。结论  3m可呈剂量依赖性地抑制皮肤鳞状细胞癌A431、Colo-16细胞的增
          殖、克隆形成、迁移、侵袭能力,其作用机制与抑制JAK2/STAT3信号通路活性,诱导细胞凋亡有关。

          ABSTRACT    OBJECTIVE  To  study  the  effect  and  mechanism  of  dihydrochromone-spliced  polycyclic  pyrrole-spiroepoxidole
          compound  3m  on  cutaneous  squamous  cell  carcinoma.  METHODS  Using  human  cutaneous  squamous  cell  carcinoma  A431  and
          Colo-16  cells  as  research  subjects,  CCK-8  assay  was  used  to  detect  the  effects  of  different  concentrations  of  3m (5,  10,  20,  40,
          80  μmol/L)  on  the  proliferation  of A431  and  Colo-16  cells  after  24,  48  and  72  hours;  the  median  inhibitory  concentration (IC50 )
          was  calculated  at  48  h  of  treatment.  A431  and  Colo-16  cells  were  divided  into  control  group,  3m  low-concentration  and  high-
          concentration groups (15, 30 μmol/L). After treated with relevant drugs or culture medium for 48 h, the morphological changes of
          cells in each group were observed by inverted microscope. Clone formation rate, migration rate and number of cell invasions, cell
          cycle  distribution  and  apoptosis  rate  were  detected.  The  phosphorylation,  or  expression  of  Janus  kinase  2/signal  transducer  and
          activator of transcription 3 (JAK2/STAT3) signaling pathway related proteins [JAK2, STAT3, B-cell lymphocyte-2 (Bcl-2), Bcl-2-
          associated  X  protein (Bax)],  and  their  mRNA  expression  in  cells  were  detected.  RESULTS  3m  could  significantly  inhibit  the
          proliferation  of A431  and  Colo-16  cells  after  treated  for  24,  48,  72  h (P<0.01),  and  IC50 of  them  were  20.36,  23.72  μmol/L,
                                                              respectively.  After  48  hours  of  treatment,  compared  with
