摘要：目的观察香砂六君子汤对脾胃虚弱型萎缩性胃炎(CAG)大鼠胃排空功能、胃蛋白酶活性、胃黏膜组织缺氧诱导因子-1α(HIF-1α)基因和蛋白表达的影响,探讨该复方防治CAG的作用机制。方法受试大鼠按随机数字表法分为空白组和造模组,采用综合法复制脾胃虚弱型CAG动物模型,成模后将模型大鼠分为模型组、阳性对照组和香砂六君子汤高、中、低剂量组。空白组和模型组大鼠每日给予10 m L/kg蒸馏水灌胃,香砂六君子汤大、中、小剂量组每日分别给予24、12、6 g/kg香砂六君子汤药液灌胃,阳性对照组每日给予0.30 g/kg维霉素药剂灌胃,连续给药120 d,检测各组大鼠胃排空功能、胃蛋白酶活性,分别采用实时荧光定量PCR和免疫组化法检测胃黏膜组织HIF-1α基因及蛋白表达。结果与空白组比较,模型组大鼠胃排空功能、胃蛋白酶活性显著降低(P<0.01),HIF-1α基因和蛋白表达水平显著升高(P<0.01);与模型组比较,香砂六君子汤各组大鼠胃排空功能、胃蛋白酶活性升高,HIF-1α基因和蛋白表达水平降低,且以香砂六君子汤高剂量组作用显著(P<0.05)。结论香砂六君子汤具有改善脾胃虚弱型CAG大鼠胃排空功能、促进胃蛋白酶活性、下调缺氧环境中HIF-1α基因和蛋白表达的作用。
Objective To study effects ofXiangsha Liujunzi Decoction (XSLJZ) on gastric emptying function, pepsin activity and expression of HIF-1α gene and protein of gastric mucosa in chronic atrophic gastritis (CAG) of rats with deficiency of spleen and stomach.Methods Rats were randomly divided into normal group and model group. The models of CAG rats with deficiency of spleen and stomach type were induced by synthetic methods. After the modeling, models rats were divided into model group, positive control group and XSLJZ high-, medium-, and low-dose groups. Normal group and model group were given 10 mL/kg distilled water every day for gavage; XSLJZ high-, medium-, and low-dose groups were given 24, 12, and 6 g/kg XSLJZ Decoction for gavage; positive control group was given 0.30 g/kg Vatacoenayme for gavage, for successive 120 d. Gastric emptying function and pepsin activity were detected, and HIF-1α gene and protein expression in gastric mucosa were detected by RT-qPCR and IHC. Results Compared with the normal group, the gastric emptying function and pepsin activity in the model group were much lower (P<0.01); expressions of HIF-1α gene and protein in gastric tissues was much higher (P<0.01). Compared with model group, XSLJZ could increase the gastric emptying function and pepsin activity significantly (P<0.05), and decrease expressions of HIF-1α gene and protein (P<0.05).Conclusion XSLJZ has functions of improving the gastric emptying function, promoting pepsin activity, and reducing expressions of HIF-1α gene and protein.
