摘要

目的：考察四君子汤含药血清（SJZ）对小肠上皮（IEC-6）细胞损伤后迁移、增殖及c-核蛋白类基因（c-Myc）mRNA和蛋白表达的影响，以探讨四君子汤促进胃肠黏膜损伤修复的作用机制。方法：采用大鼠制备四君子汤含药血清，Tips划痕法建立IEC-6细胞迁移模型，观察四君子汤药物血清对细胞迁移的影响；实时细胞分析仪（RTCA）检测四君子汤含药血清对IEC-6细胞增殖的影响；实时荧光定量PCR（Real-time PCR）法检测c-Myc mRNA表达；蛋白免疫印迹（Western blot）法检测c-Myc蛋白表达。结果：中体积浓度（10%）和高体积浓度（20%）的四君子汤含药血清可促进IEC-6细胞迁移（P<0.01）；细胞损伤后12 h，中体积浓度（10%）和高体积浓度（20%）的四君子汤含药血清可促进IEC-6细胞增殖（P<0.01）；细胞损伤后24 h和36 h，低（5%），中（10%），高（20%）体积浓度的四君子汤含药血清均可促进IEC-6细胞增殖（P<0.05，P<0.01）；进一步研究发现，中体积浓度（10%）和高体积浓度（20%）的四君子汤含药血清可提高与胃肠黏膜损伤修复密切相关的c-Myc mRNA和蛋白表达（P<0.01）。结论：四君子汤修复胃肠黏膜屏障损伤，促进溃疡愈合的作用可能与其提高c-Myc mRNA和蛋白表达，促进黏膜上皮细胞的迁移和增殖有关。

Abstract

Objective: To study the effect of Sijunzi Tang (SJZT)-containing serum on cell migration and proliferation

c-Myc mRNA and protein expression of injured intestinal epithelial (IEC-6) cell

so as to explore the mechanism of SJZT in promoting gastrointestinal mucosal injury repair. Method: Rats were selected to prepare SJZT-containing serum

and IEC-6 cell migration model was established by tips scratch method

so as to observe the effect of SJZT on cell migration. Real-time cell analyzer (RTCA) was used to determine the effect of SJZT-containing serum on IEC-6 cell proliferation

c-Myc mRNA and protein expressions were detected by Real-time PCR and Western blot analysis

respectively. Result: The 10% and 20% SJZT-containing serum stimulated IEC-6 cell migration 8 h after cell damage (P<0.01); 10% and 20% SJZT-containing serum increased IEC-6 cell proliferation 12 h after cell damage (P<0.01). 5%

10%

and 20% SJZT-containing serum enhanced IEC-6 proliferation both at 24

36 h after damage (P<0.05

P<0.01). Further studies showed that

10% and 20% SJZT-containing serum increased c-Myc mRNA and protein expressions that were closely correlated with gastrointestinal mucosal injury repair (P<0.01). Conclusion: Sijunzi Tang-containing serum can repair the injury of gastrointestinal mucosal barrier

the mechanism may be related to its effect in improving mucosal c-Myc mRNA and protein expressions and promoting IEC-6 cell migration and proliferation.
