摘要
目的:探究黄芪对2型糖尿病大鼠碱性磷酸酶、细菌内毒素和血清中炎症因子的影响。方法:采用高糖高脂饮食+链脲佐菌素腹腔注射建立2型糖尿病模型,连续给予大鼠灌胃黄芪水溶液(0.25、0.5 g/kg),测定大鼠体质量及血糖变化、粪便中肠道碱性磷酸酶(IAP)的活力及细菌内毒素(LPS)的浓度变化并用MSD多因子方法检测血清中炎症因子(白介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、γ干扰素(IFN-γ)、白细胞介素-1(IL-1β)、白介素-4(IL-4)、白介素-5(IL-5)、白介素-10(IL-10)、白介素-13(IL-13)、生长调节致癌基因α(KC/GRO))浓度变化的分析。结果:与模型组相比,黄芪剂量组空腹血糖浓度显著降低(P<0.05),IAP活力显著增加(P<0.05),LPS浓度显著降低(P<0.05),且血清中促炎因子IL-6、TNF-α、IFN-γ、IL-1β的浓度显著减少(P<0.05),而抗炎因子IL-4、IL-5、IL-10、IL-13的浓度显著增加(P<0.05),趋化因子KC/GRO的浓度显著下降(P<0.05)。结论:黄芪可以促进肠碱性磷酸酶活性,并能够有效调节T2DM小鼠血糖及炎症反应。
Objective:To explore the effects of Astragalus on alkaline phosphatase,bacterial endotoxin and serum inflammatory factors in type 2 diabetes rats.Methods:A high-sugar and high-fat diet+intraperitoneal injection of streptozotocin was used to establish a type 2 diabetes model.The rats were continuously administered Astragalus aqueous solution(0.25,0.5 g/kg)and measureed the changes in body mass,blood sugar,the activity of intestinal alkaline phosphatase(IAP)in feces and the changes in bacterial endotoxin(LPS)concentration.MSD multi-factor method was used to detect serum inflammatory factors(Interleukin-6(IL-6),Tumor necrosis factor-α(TNF-α),Interferon-γ(IFN-γ),Interleukin-1(IL-1β),Interleukin-4(IL-4),Interleukin-5(IL-5),Interleukin-10(IL-10),interleukin-13(IL-13)growth regulatory oncogeneα(KC/GRO))concentration changes.Results:Compared with the model group,the fasting blood glucose concentration in the Astragalus dose group was significantly reduced(P<0.05),the IAP activity was significantly increased(P<0.05),the LPS concentration was significantly reduced(P<0.05),and the concentration of serum proinflammatory factors IL-6,TNF-α,IFN-γand IL-1βwere significantly reduced(P<0.05),while the concentration of antiinflammatory factors IL-4,IL-5,IL-10,and IL-13 increased significantly(P<0.05),the concentration of chemokine KC/GRO decreased significantly(P<0.05).Conclusion:Astragalus could promote the activity of intestinal alkaline phosphatase and effectively regulate blood sugar and inflammation in T2 DM mice.
