    • 摘要: Objective To explore the protective effects and possible mechanisms of hesperetin against isoproterenol (ISO)-induced heart failure (HF) in rats.Methods Forty Sprague-Dawley (SD) rats were randomly divided into four groups:control group(group C),hesperetin group (group H),isoproterenol group (group Ⅰ)and H+ Ⅰ group (group T).Rats in group Ⅰ and group T were subcutaneously injected with ISO (150 mg/kg) once a day for 2 consecutive days.The model was successfully established in heart failure was determined by echocardiography after 2 weeks.Hesperetin was administered at the dosage of 100 mg/kg,po by gavage for a period of 10 days in group H and group T.Cardiac function of all rats including left ventricular end-diastolic diameter (LVEDD),left ventricular end-systolic dimension (LVESD),left ventricular ejection fractions (EF),left ventricular fractional shortening (FS) was assessed by echocardiography.Collecting serum of all rats,malondialdehyde (MDA),superoxide dismutase (SOD),total antioxidant capacity (TAOC) were detected by thiobarbiturieacid colorimetry,WST-1 method and colorimetry method respectively.Results There was not obvious changes of cardiac function in group C and group H.ISO inhibited the cardiac function of rats significantly including LVESD,EF,as well as FS,compared to group C(P <0.05).LVESD was increased while EF and FS were decreased.The level of MDA in group Ⅰ was significantly higher (P <0.05) while the levels of SOD and TAOC were significantly lower than group C (P <0.05).Hesperetin attenuated the effect of heart failure induced by ISO.Cardiac function of rats including LVESD,EF,as well as FS was improved in group T compared to group Ⅰ (P <0.05).LVESD was declined,EF and FS were ascended.The level of MDA was significantly lower,the levels of SOD,TAOC in group T were significantly higher than that in group Ⅰ (P <0.05).Conclusion Hesperetin can attenuate ISO-induced heart failure in rats.Its possible mechanisms may be associated with regulating oxidative stress.%目的 观察橙皮素对大剂量异丙基肾上腺素(ISO)诱导大鼠心衰的保护作用,并探讨其机制.方法 将SD大鼠随机分为正常(C)组、橙皮素对照(H)组、异丙基肾上腺素(Ⅰ)组和橙皮素治疗+Ⅰ(T)组,l组和T组接受皮下注射大剂量ISO(150 mg/kg),2周后行超声心动图检测.确定造模成功后,H组及T组给予橙皮素(100 mg/kg)灌胃,Ⅰ组给予等量的溶剂乙醇,连续给药10d后测定各组大鼠心脏功能包括左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)、左室射血分数(EF)、左室缩短分数(FS)变化及血清丙二醛(M DA)、超氧化物歧化酶(SOD)、总抗氧化能力(TAOC)的变化,观察各组大鼠心肌的病理变化.结果 与C组比较,I组LVEDD变化不大,LVESD值增大、EF、FS降低,氧化应激指标中MDA值升高,SOD、TAOC降低,备指标差异有统计学意义(P<0.05);与I组比较,T组大鼠LVEDD无明显变化,LVESD降低,EF、FS升高,血清MDA值降低,SOD、TAOC升高,各指标差异有统计学意义(P<0.05).H组各指标较C组无明显变化.结论 橙皮素可能通过减轻氧化应激,降低MDA,升高SOD、TAOC,从而改善心衰大鼠的心脏功能.

    • 摘要: 目的:探讨β-肾上腺素受体(β-AR)激动剂异丙基肾上腺素(ISO)2种给药模式对小鼠心脏腺苷酸活化蛋白激酶( AMPK)活性的影响,以及AMPK激动剂在这2种模式中对心脏结构和功能的不同作用。方法:采用皮下植入微渗透压泵的方法给予雄性BALB/c小鼠持续14 d输注ISO(5 mg· kg-1· d-1)以及每日皮下注射AMPK激动剂AICAR(250 mg· kg -1· d-1)。分别于植入泵14 d后和植入泵14 d并撤泵3 d后,利用超声心动图和血流动力学方法检测心脏功能并收集心脏样本。 Western blot检测AMPK的磷酸化水平。结果:持续输注ISO 14 d后心脏AMPK的磷酸化水平较对照组明显增加(P<0.05),AICAR并不进一步增加AMPK磷酸化水平,反而有减少ISO引起的心脏AMPK磷酸化水平增加的趋势。 AICAR明显抑制ISO引起的心脏重量增加。反映心脏收缩功能的左室短轴缩短率(FS)和左心室压力最大上升速率(+dp/dtmax)在ISO组显著高于对照组(P<0.05), AICAR并不进一步增加心脏收缩功能。反映心脏舒张功能的左室舒张末压( LVEDP)在各组并无明显改变。持续输注异丙基肾上腺素14 d并撤泵3 d后心脏AMPK的磷酸化水平与对照组的差异无统计学显著性。 AICAR明显抑制ISO引起的心脏重量增加。+dp/dtmax在ISO组明显低于对照组(P<0.05),提示收缩功能下降。 AICAR+ISO组与ISO组相比,有增加+dp/dtmax的趋势。反映心脏舒张功能的LVEDP在ISO组明显升高(P<0.05),提示舒张功能明显降低。而AICAR则显著改善了ISO引起的舒张功能异常(P<0.05)。给予ISO后,AMPK磷酸化水平增加和心率增加的时间曲线一致,均为5 min开始升高,30 min开始下降至基础水平。结论:β-AR持续激动使AMPK活性持续升高,而撤泵后AMPK活性则降至对照水平。观察AMPK激动对心脏功能的改善作用需避免β-AR激动引起的正性变时变力效应的干扰。%[ ABSTRACT] AIM:To investigate the cardiac AMP-activated protein kinase ( AMPK) activity and the effects of AMPK activator on cardiac structure and function in the mice with different β-adrenoceptor (β-AR) stimulation patterns . METHODS:Male BALB/c mice were subcutaneously injected with AMPK activator ( AICAR, 250 mg· kg -1 · d-1 ) or saline, and infused with β-AR agonist isoproterenol (ISO, 5 mg· kg-1· d-1) for 14 d.The cardiac functions were evalu-ated by echocardiography or hemodynamic method , and the hearts were harvested after infusion cessation immediately or 3 d later.Phosphorylated AMPK ( p-AMPK) was measured by Western blot .RESULTS:Sustained ISO infusion increased p-AMPK level.AICAR did not further increase p-AMPK but attenuated ISO-induced increase in heart weight .Sustained ISO infusion increased cardiac systolic function as indicated by left ventricular fractional shortening ( FS) and maximum rate of pressure rise (+dp/dtmax).The cardiac systolic function was not further increased by AICAR .The cardiac diastolic func-tion as indicated by left ventricular end-diastolic pressure (LVEDP) was not different in each group .In contrast, cardiac p-AMPK level was similar between the control mice and the mice with sustained ISO infusion and ceased infusion for 3 d. In this model, AICAR improved the cardiac systolic and diastolic functions , which were impaired by ISO.Moreover, the increased pattern of p-AMPK level was similar with that of heart rate upon ISO stimulation .CONCLUSION: Sustained ISO infusion increases p-AMPK.After ISO infusion cessation for 3 d, p-AMPK is decreased to the basal level .β-AR-in-duced inotropic effects should be avoided to investigate the cardioprotective role of AMPK activation in the β-AR stimulation models.

    • 摘要: Isoproterenol (ISPR) is an important catecholamine‐based drug that is widely used in the treatment of heart disease. However, overdose of this drug is very dangerous to the human body. In this study, a new sensor based on a pyrogallol red modified‐multiwalled carbon nanotube paste electrode (PGRMMWCNTPE) was prepared and used for high sensitivity determination of ISPR in aqueous solution. Electrocatalytic oxidation of ISPR at the PGRMMWCNTPE was investigated by chronoam‐perometry, cyclic voltammetry, and square‐wave voltammetry. The values of the catalytic rate con‐stant, electron transfer coefficient, and diffusion coefficient for ISPR oxidation were then calculated using voltammetric data. A linear calibration curve was constructed for ISPR concentration in the range 0.8–570μmol/L with a detection limit of 0.47μmol/L ISPR. The sensor was then applied to the determination of ISPR in urine and drug samples with satisfactory results.%异丙基肾上腺素(ISPR)是一种重要的邻苯二酚胺类药物,广泛用于治疗心脏疾病.然而,过量服用该药对人体非常危险.本文采用邻苯三酚红修饰多壁碳纳米管糊电极(PGRMMWCNTPE)制备了一种新型传感器,用于高灵敏度检测水溶液中的ISPR.采用计时电流法、循环伏安法和方波伏安法考察了PGRMMWCNTPE电极电催化氧化ISPR性能.通过伏安数据计算了ISPR氧化的催化反应速率常数、电子传递系数和扩散系数.在ISPR浓度0.8–570μmol/L范围内建立了线性标准曲线,检测限为0.47μmol/L ISPR.将该传感器用于尿液和药物样品中ISPR检测得到满意结果.

    • 摘要: Objective:To explore the effect of gingko flavonoids on the content of SOD and MDA and cardiac function in the rats with heart failure. Methods:Totally 40 male Sprague-Dawley rats were randomly divided into 5 groups by random number table meth-od, namely the blank group, the model group, low-dose gingko flavonoids group, high-dose gingko flavonoids group and metoprolol group. Except the blank group, all the other groups were subcutaneously injected 300 mg·kg-1 isopropyl adrenaline for two days to make the heart failure model. After that, metoprolol group was given metoprolol 20 mg·kg-1 ·d-1 , the ginkgo flavonoids group was given 250 or 500 mg·kg-1 ·d-1 ginkgo flavonoids extract, the other groups were given physiological saline with the same volume, and the treatment course was 8 weeks. After the treatment, cardiac function indices ( IVST, LVPWT, LVEDD, LVESD and LVEF) , SOD and MDA levels in cardiac muscle tissue and the pathological integral, and myocardial pathologic morphology characteristics were deter-mined. Results:LVEDD and LVESD of the two ginkgo flavonoids groups and metoprolol group were obviously improved compared with those of the model group, while LVEF, IVST and LVPWT were significantly decreased (P<0. 05), showing that the cardiac function was improved after the treatment. The levels of SOD were raised, while MDA and the pathological integral were decreased significantly in the two ginkgo flavonoids groups compared with those of the model group (P<0. 05), with a dose-dependant relationship. Conclu-sion:Ginkgo flavonoids have certain protective effect in heart failure rats, and the mechanism may be related to reducing the level of lipid peroxidation and improving the body antioxidant enzyme activity.%目的::探讨银杏总黄酮对心力衰竭大鼠心功能及心肌组织超氧化物歧化酶( SOD)和丙二醛( MDA)含量变化的影响。方法:SPF级雄性SD大鼠40只,随机分为5组:空白组、模型组、银杏总黄酮低剂量组、高剂量组和美托洛尔组。除空白组外其余均给予皮下注射异丙基肾上腺素300 mg·kg-1·d-1,持续2 d,造模成功后美托洛尔组给予美托洛尔20 mg·kg-1·d-1,银杏总黄酮高低剂量组分别给予500、250 mg·kg-1·d-1的银杏总黄酮,空白组和模型组灌胃给予相同体积的生理盐水,共给药8周。于给药8周后测定大鼠心功能指标包括室间隔厚度( IVST)、左心室后壁厚度( LVPWT)、左心室舒张末内径( LVEDD)、左心室收缩末内径( LVESD)和左心室射血百分数( LVEF),心肌组织SOD、MDA含量和病理积分,并取心肌组织染色观察病理形态学特征。结果:给药8周后,银杏总黄酮组高、低剂量组和美托洛尔组LVEF、IVST和LVPWT降低,LVEDD、LVESD升高,与模型组比较差异显著(P<0.05);银杏总黄酮高、低剂量组SOD水平上升,MDA含量和病理评分明显下降,与模型组比较差异有统计学意义(P<0.05),且随剂量加大有剂量依赖性趋势。结论:银杏总黄酮对心衰大鼠的心功能具有一定的保护作用,其作用机制可能与降低脂质过氧化水平,提高机体抗氧化酶活性有关。
