摘要:

目的 观察运脾调脂方通过腺苷酸活化蛋白激酶(AMPK)-过氧化物酶体增殖物激活受体(PPAR)α-固醇调节元件结合蛋白(SREBP)轴及相关靶点对高脂血症大鼠血脂水平、肝脏脂质沉积及肝肾功能和血糖(Glu)的影响,评价其有效性及安全性。方法 将SPF级SD大鼠60只随机分为空白组,模型组,运脾调脂方低、中、高剂量(0.4、0.8、1.6 g/kg)组及阿托伐他汀组,每组10只。除空白组外,其余组均以高脂饲料联合腹腔注射维生素D3(VitD3)造模6周,后各组分别给予相应药物灌胃6周。于干预前及末次给药后检测血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、尿素氮(BUN)、血肌酐(Scr)、尿酸(UA)及Glu;对各组进行肝组织病理学观察,并进行非酒精性脂肪性肝病(NAFLD)活动度评分(NAS);Western blot 检测肝组织脂质代谢关键蛋白。结果 治疗前,与空白组比较,模型组及各干预组TC、TG、HDL-C、LDL-C水平均升高(P<0.01)。治疗后,与模型组比较,运脾调脂方各剂量组TC、LDL-C、ALT、Scr、SREBP-1c表达水平均下降,p-AMPK/AMPK及PPARα表达水平均升高(P<0.05),AST、UA和Glu比较差异无统计学意义;高剂量组TG、脂肪变性评分、气球样变评分、小叶炎症评分、NAS总分、BUN下降,阿托伐他汀组Glu水平升高(P<0.05)。各组ALT、BUN、Scr及UA水平均处于正常范围。结论 运脾调脂方可通过调控AMPK-PPARα-SREBP轴改善高脂血症大鼠脂质代谢,减轻肝脂肪变性,且对肝肾功能及Glu无不良影响。

Abstract:

Objective To investigate the effects of the Yunpitiaozhi formula on the lipid levels, liver lipid deposition, liver and kidney functions and blood glucose (Glu) through the adenylate activated protein kinase (AMPK)?peroxisome proliferator-activated receptor (PPAR) α -sterol regulatory element binding protein (SREBP) axis and related targets in hyperlipidemic rats, and to evaluate its efficacy and safety. Methods Sixty SPF-grade SD rats were randomly divided into the blank group, the model group, the low, medium and high-dose groups of the Yunpitiaozhi formula (0.4, 0.8 and 1.6 g/kg), and the atorvastatin group. Each group consisted of 10 rats. Except for the blank group, all groups were induced with high-fat diet combined with intraperitoneal injection of vitamin D3 for 6 weeks. Then, each group was given the corresponding drug by gavage for 6 weeks. Serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) and Glu were detected before and after the intervention. Liver tissue pathological observation was conducted for each group, and the non-alcoholic fatty liver disease (NAFLD) activity score (NAS) was evaluated. Western blot assay was used to detect key proteins of lipid metabolism in liver tissue. Results Before treatment, compared with the blank group, the TC, TG, HDL-C and LDL-C levels were increased in the model group and all intervention groups (P<0.01). After treatment, compared with the model group, the expression levels of TC, LDL-C, ALT, Scr and SREBP-1c decreased in each dose group of the Yunpitiaozhi formula, and the p-AMPK/AMPK ratio and PPARα expression level increased (P<0.05). There were no statistically significant differences in AST, UA and blood glucose between the groups. In the high-dose group, TG, steatosis score, ballooning score, lobular inflammation score, NAS total score and BUN decreased, and the Glu level increased in the atorvastatin group (P < 0.05). The ALT, BUN, Scr and UA levels were within the normal range in each group. Conclusion Yunpitiaozhi formula can improve lipid metabolism in hyperlipidemic rats by regulating the AMPK-PPARα-SREBP axis, alleviate liver steatosis, and has no adverse effects on liver and kidney functions and blood glucose.
