          摘  要  目的  基于干细胞因子(SCF)/干细胞因子受体(c-kit)信号通路探讨三七总皂苷(PNS)对慢性萎缩性胃炎(CAG)大鼠胃
          黏膜损伤、炎症反应的影响及潜在机制。方法  取SD雄性大鼠,以N-甲基-N′-硝基-N-亚硝基胍灌胃诱导+不规律饮食的方式构建
          CAG大鼠模型,并将造模成功的大鼠随机分为模型组(Model组),阳性对照-维酶素组(Positive组,250 mg/kg),PNS低、高剂量组
         (PNS-L、PNS-H组,9、18 mg/kg),PNS高剂量+SCF/c-kit抑制剂组(PNS-H+ISCK03组,18 mg/kg+47 mg/kg),每组8只;另取健康大
          鼠8只,作为对照组(Control组)。末次给药后,检测各组大鼠血清中胃泌素(GAS)、胃动素(MTL)水平和胰多肽(PP)活性,以及
          胃黏膜组织中肿瘤坏死因子α(TNF-α)、白细胞介素10(IL-10)、IL-8水平;观察其胃黏膜组织病理变化及上皮细胞超微结构,并进
          行胃黏膜萎缩评分;检测其胃黏膜组织细胞凋亡情况及增殖细胞核抗原(PCNA)、核因子κB p65(NF-κB p65)、SCF、c-kit蛋白的表
          达情况。结果  与Control组比较,Model组大鼠胃黏膜组织炎症细胞浸润明显,大量上皮细胞脱落且超微结构受损严重;胃黏膜萎
          缩评分、胃黏膜组织中TNF-α和IL-8水平、细胞凋亡率、NF-κB p65蛋白的表达均显著升高或上调;血清中GAS、MTL水平和PP活
          性,胃黏膜组织中IL-10水平,以及PCNA、SCF蛋白的表达和c-kit蛋白的磷酸化水平均显著降低或下调(P<0.05)。与Model组比
          较,Positive、PNS-L、PNS-H组大鼠胃黏膜组织中上述病理改变均明显好转,各定量指标均显著改善,且PNS-H组的改善较PNS-L
          组更显著(P<0.05);而ISCK03可显著逆转高剂量PNS对大鼠上述指标的改善作用(P<0.05)。结论  PNS可通过减轻炎症反应、
          促进胃黏膜修复,从而改善CAG大鼠胃黏膜损伤;上述作用可能与激活SCF/c-kit信号通路有关。

          chronic atrophic gastritis

          ABSTRACT   OBJECTIVE  To  investigate  the  effects  and  potential  mechanism  of  Panax  notoginseng  saponins (PNS)  on  gastric
          mucosal  injury  and  inflammatory  response  in  rats  with  chronic  atrophic  gastritis (CAG)  via  the  stem  cell  factor(SCF)/cellular
          tyrosine  kinase  receptor(c-kit)  signaling  pathway.  METHODS  Male  SD  rats  were  used  to  establish  a  CAG  rat  model  through
          intragastric administration of N-methyl-N′-nitro-N-nitrosoguanidine combined with an irregular diet. Successfully modeled rats were
          randomly divided into a model group, positive control-vitacoenzyme group (Positive group, 250 mg/kg), PNS low- and high-dose
          groups (PNS-L  and  PNS-H  groups,  9,  18  mg/kg),  and  high-dose  PNS+SCF/c-kit  inhibitor  group (PNS-H+ISCK03  group,  18
          mg/kg+47  mg/kg),  with  8  rats  in  each  group.  Additionally,  8  healthy  rats  were  selected  as  a  control  group.  After  the  final
          administration,  the  activities  of  serum  gastrin (GAS),  motilin (MTL)  and  pancreatic  polypeptide (PP),  as  well  as  the  levels  of
          tumor  necrosis  factor-α (TNF-α),  interleukin-10 (IL-10),  and  IL-8  in  gastric  mucosal  tissues,  were  measured  in  each  group.
          Pathological changes of the gastric mucosal and ultrastructure of the epithelial cells were observed, and gastric mucosal atrophy was
          scored.  Cell  apoptosis  in  gastric  mucosal  tissues  and  the  expressions  of  proliferating  cell  nuclear  antigen (PCNA),  nuclear  factor-
          κB  p65 (NF- κB  p65),  SCF  and  c-kit  were  detected.  RESULTS  Compared  with  the  control  group,  the  model  group  showed
          significantly  increased  inflammatory  cell  infiltration  in  the  gastric  mucosal,  extensive  epithelial  cell  detachment,  severe
          ultrastructural  damage,  and  significantly  elevated  or  up-regulated  gastric  mucosal  atrophy  score, TNF-α  and  IL-8  levels  in  gastric
          mucosal,  cell  apoptosis  rate,  and  NF-κB  p65  protein  expression.  Meanwhile,  serum  levels  of  GAS  and  MTL,  PP  activity,  the
          level of IL-10 in gastric mucosal tissue, and protein expressions of PCNA and SCF, as well as the phosphorylation level of c-kit,
          were  significantly  decreased  or  down-regulated (P<0.05).  Compared  with  the  model  group,  Positive,  PNS-L  and  PNS-H  groups
                                                             exhibited  markedly  improved  pathological  changes  in  the
