目的:研究复方蜥蜴散不同微粒组合剂对胃癌前病变大鼠Stat3通路Stat3、Bcl-2、Bcl-xL蛋白表达的影响,探讨复方蜥蜴散不同微粒组合剂对胃癌前病变抗凋亡蛋白的调控机制.
方法:将120只SD雄性大鼠随机分成空白对照组、复方蜥蜴散不同微粒组合剂80目治疗组、100目治疗组、80目和100目等量混合治疗组、胃癌前病变模型对照组、维酶素治疗组,除空白对照组外,均用N-甲基-N ′-硝基-N-亚硝基胍、饥饱失常及情绪刺激综合因素8周制备胃癌前病变大鼠模型.分别用复方蜥蜴散不同微粒组合剂80目、100目、80目100目等量混合糊剂混悬液、生理盐水、维酶素治疗,观察大鼠胃黏膜病理组织学变化及应用免疫组化法检测胃体组织Stat3、Bcl-2、Bcl-xL蛋白表达情况.
结果:通过Image-Pro Plus 6.0图像分析系统对免疫组化图像进行光密度的测算,复方蜥蜴散不同微粒组合剂80目治疗组、100目治疗组、80目和100目等量混合治疗组Stat3、Bcl-2、Bcl-xL蛋白阳性表达率低于维霉素治疗组(P<0.05),其中以复方蜥蜴散80目100目等量混合治疗组差异最显著(P<0.01).
结论;复方蜥蜴散不同微粒组合剂能部分逆转胃黏膜病理变化,降低Stat3、Bcl-2、Bcl-xL蛋白的表达,促进细胞凋亡,抑制细胞过度增殖,恢复细胞增殖与凋亡的平衡,揭示了复方蜥蜴散不同微粒组合剂可能是通过对抗凋亡蛋白的调控实现治疗胃癌前病变的作用机制的.

胃食管反流病是临床常见病,中医药治疗本病在降低复发率、改善预后、减少对于抑酸药物的依赖和副作用等方面具有一定优势和特色.现对近十年来中医药辩证治疗胃食管反流病的临床研究,指出本病的病位在食管和胃,与肝胆脾肺关系密切,本病正虚为本,以脾胃虚损为主,邪实为标,以气郁、食滞、痰凝为主。现代医家根据本病的发病部位、相关脏腑以及病机演变过程,将本病的临床常见证型概括为肝胃不和证、肝胃郁热证、痰气郁阻证、脾胃
