目的 观察橙皮苷改善庆大霉素致小鼠急性肾损伤的作用,并探讨该作用与炎症与凋亡的相关性.方法 将小鼠随机分为正常组、模型组、维拉帕米组(21.43 mg/kg)及橙皮苷低、高剂量组(100、200 mg/kg),采用腹腔注射庆大霉素法建立AKI模型,随后各组给予相应药物干预14 d.给药结束后检测小鼠24 h尿蛋白、肾脏指数、肾功能指标,采用ELISA法检测血清及肾组织IL-10、IL-6、TNF-α水平,HE染色检测肾组织病理损伤,TUNEL染色检测肾组织细胞凋亡,RT-qPCR法检测肾组织caspase-3、Bcl-2、Baxm RNA表达,Western blot法检测肾组织cleaved caspase-3及PI3K/Akt信号通路相关蛋白表达.结果 与模型组比较,橙皮苷各剂量组小鼠24 h尿蛋白及肾脏指数降低(P<0.05),肾组织病理损伤有不同程度的改善,血清BUN、Scr及CysC水平降低(P<0.05),血清及肾组织IL-10水平升高(P<0.05),IL-6、TNF-α 水平降低(P<0.05),肾组织细胞凋亡率、caspase-3、Bax mRNA 表达及 cleaved caspase-3蛋白表达降低(P<0.05),Bcl-2 mRNA表达及PI3K、p-Akt蛋白表达升高(P<0.05).结论 橙皮苷对庆大霉素致小鼠急性肾损伤具有一定的改善作用,该作用与其抑制炎症及通过调控PI3K/Akt信号通路而产生的抗凋亡活性有关.
Effects of hesperidin on gentamicin-induced acute kidney injury,inflammation and apoptosis in mice
AIM To observe the ameliorative effects of hesperidin on gentamicin-induced acute kidney injury(AKI)in mice,and to explore the correlation between the effects and inflammation and apoptosis.METHODS The mice were randomly divided into the normal group,the model group,the verapamil group(21.43 mg/kg)and the low and high dose hesperidin groups(100,200 mg/kg).With the AKI model established by intraperitoneal injection of gentamicin,the mice of each group underwent 14 days corresponding drug administration.After the intervention,the mice had their levels of 24-hour urine protein,renal index and renal function indexes detected;their levels of IL-10,IL-6 and TNF-α in serum and kidney tissue detected by ELISA;their renal pathological damage detected by HE staining;their renal apoptosis detected by TUNEL staining;their renal mRNA expressions of caspase-3,Bcl-2 and Bax detected by RT-qPCR;and their renal expressions of cleved caspase-3 and PI3K/Akt signaling pathway related proteins detected by Western blot.RESULTS Compared with the model group,the hesperidin groups displayed decreased levels of 24-hour urinary protein and renal index(P<0.05);improved renal pathological damage in varying degrees;decreased levels of serum BUN,Scr and CysC(P<0.05);increased IL-10 levels of serum and renal tissue(P<0.05);decreased levels of IL-6 and TNF-α(P<0.05);decreased renal apoptosis rate,caspase-3,Bax mRNA expressions and cleaved caspase-3 protein expression(P<0.05);and increased expressions of Bcl-2 mRNA and PI3K/Akt proteins(P<0.05).CONCLUSION Hesperidin can ameliorate gentamicin-induced AKI in mice,which is related to its anti-inflammatory efficacy and anti-apoptotic activity via PI3K/Akt signaling pathway.
