摘要: 目的 探讨健脾清化舒络中药对慢性萎缩性胃炎(CAG)大鼠Sonic Hedgehog信号通路的影响。方法 雄性Wistar大鼠59只,随机分为空白对照组16只、造模组43只,采用复合造模法进行病证结合CAG模型构建,期间随机抽取造模组大鼠3只验证CAG造模是否成功。造模成功后,予健脾清化舒络中药(复方胃炎合剂)进行相关干预。具体干预方案为:将空白对照组随机分为空白组、健脾清化舒络中药高剂量[61.04 g/(kg·d)]空白组,造模组随机分为CAG模型组、维酶素[0.2 g/(kg·d)]组和健脾清化舒络中药低、中、高剂量[15.26、30.52、61.04 g/(kg·d)]组,每组8只,给予相应药物连续干预4周。检测大鼠胃组织Shh、Ptch1、Smo、Gli1、Gli2、Gli3、Sufu蛋白表达水平及血清中白细胞介素-1β(IL-1β)、胃泌素(GAS)含量。结果 与空白组比较,模型组大鼠Shh、Ptch1、Smo、Gli1蛋白表达及血清GAS水平降低,Gli2、Gli3、Sufu蛋白表达及血清IL-1β水平上升,差异均有统计学意义(P<0.05、P<0.01)。与CAG模型组比较,健脾清化舒络中药低、中、高剂量组胃黏膜病变显著改善,Shh、Ptch1、Smo、Gli1蛋白表达上调,Gli2、Gli3、Sufu蛋白表达下调,血清IL-1β水平降低,差异均有统计学意义(P<0.05、P<0.01),健脾清化舒络中药中、高剂量组血清GAS水平上升(P<0.05)。结论 健脾清化舒络中药可有效改善CAG大鼠胃黏膜组织病理改变,其机制可能与调控血清IL-1β、GAS含量,重新激活下游Sonic Hedgehog信号通路的表达有关。

Abstract: Objective To explore the effect of spleen-fortifying, fire-clearing and collateral-unblocking (SFC) medicinals on Sonic Hedgehog signal pathway in rats with chronic atrophic gastritis (CAG). Methods 59 male wistar rats were randomly divided into the control group (n = 16) and model group (n = 43). The CAG model was established by comprehensive modeling method. After that, 3 rats in the model group were randomly selected for gastric pathological examination. After the model was successfully established, the compound gastritis mixture (under the guidance of the SFC method) was given as a representative drug for relevant intervention. Specifically, the control group was randomly divided into blank group, blank + high dose SFC group, while the model group was randomly divided into CAG group, Vitacoenzyme group, low dose, medium dose and high dose SFC groups (n=8). The corresponding drugs were given continuously for 4 weeks. At last, the protein expression levels of Shh, Ptch1, Smo, Gli1, Gli2, Gli3 and Sufu in gastric tissue and the concentration of IL-1 β and GAS in serum were measured. Results In the model group, the expression of Shh, Ptch1, Smo, Gli1 protein and the level of serum GAS decreased, while the expression of Gli2, Gli3, Sufu protein and the level of serum IL-1β increased (P<0.05, P<0.01). Compared with the CAG group, the pathological changes of gastric mucosa in the low, middle and high dose SFC groups were significantly improved, the expression of Shh, Ptch1, Smo and Gli1 protein increased, and the expression of Gli2, Gli3, Sufu protein and the level of serum IL-1β decreased (P<0.05, P<0.01). The level of serum GAS in middle and high dose SFC groups increased significantly (P<0.05). Conclusion SFC method could possibly improve the pathological changes of CAG in rats, and its mechanism may be related to improving the contents of serum IL-1β and GAS and reactivating the expression of Sonic Hedgehog signal pathway.
