Objective:To study the effect of diammonium glycyrrhizinate (DG) on left ventricular function impairment during myocardial ischemia-reperfusion in rats. Methods:The left ventricular was cannulated through right common carotid artery on the myocardial ischemia-reperfusion injury model. The left ventricler function was assessed before and 10 minutes after the administration of DG, immediate and 20 minutes after initiation of ischemia, immediate and 30, 60 minutes after reperfusion, by measuring the left ventricular systolic pressure (LVSP), left ventricular end diastolic pressure (LVEDP), +dp*dtmax and -dp*dtmax. Results:Compared with the baseline, all measurements of LVSP, +dp*dtmax and -dp*dtmax decreased (P<0.05,P<0.01), while LVEDP increased (P<0.01) after administration of DG. As the time of ischemia-reperfusion lasting, LVSP, dp*dtmax and -dp*dtmax generally decreased progressively, while LVEDP generally increased progressively. 20 minutes after the initiation of ischemia and immediate, 30 and 60 minutes following reperfusion, LVSP, +dp*dtmax and -dp*dtmax in the DG group were significantly higher than those in IR group (P<0.01), LVEDP significantly lower than that in IR group (P<0.01) at the same time. Conclusion:DG can protect left ventricular function against myocardial ischemia-reperfusion injury in rats.

Objective To observe the effects of diammonium glycyrrhizinate (DG) on arrhythmia induced by acute myocardial ischemia-reperfusion injury.Methods Electrocardiogram of lead Ⅱwas examined on the myocardial ischemia-reperfusion model,which was induced by the 10 min of ligation of left descending coronary artery and then 30 min of reperfusion in rats.Myocardial malondialdehyde (MDA) content,superoxide dismutase (SOD) activity and adenosine triphosphatase (ATPase),and serum lactate dehydrogenase (LDH) and creatine phosphokinase (CK) levels were measured.Results As compared with the model,DG significantly reduced the incidence of ventricular arrhythmia and its score (P

Aim To investigate the effects of anisodamine on the pressure of portal vein of experimental liver fibrosis and its mechanisms of action. Methods The experimental liver fibrosis model was produced by CCl_4. The preventive group was treated ten weeks with anisodamine 7.0 mg?kg~(-1) ip once everyday. All therapeutic groups were treated six weeks with anisodamine 7.0 mg?kg~(-1) or 14.0mg?kg~(-1) ip once everyday. After CCl_4 injection for ten weeks, the pressure of portal vein,the content of NO in livers, and liver iNOS and eNOS mRNA expressions were detected with different methods.Results The pressure of portal vein was significantly reduced in anisodamine preventive group and anisodamine therapeutic groups. The liver content of NO and the expression of iNOS and eNOS were all inhibited by the treatment of anisodamine.Conclusion Anisodamine reduced the expressions of iNOS and eNOS to synthesis of NO in liver. As a result, the pressure of portal vein of fibrosis rats decreased. So Portal hypertension of liver fibrosis may be improved by anisodamine in patients.

Objective:To examine the effects of bilobalide on ischemia reperfusion injury (IRI) of skeletal muscle cells in rats.Methods:IRI of skeletal muscle cells in L6 rats was stimulated by culturing skeletal muscle cells in a hypoxia incubator for 4 hours, which were further cultured in a conventional incubator for 4 hours. The induced rat myoblasts were randomly divided into control group, ischemia reperfusion group and bilobalide group. Rat myoblasts in control group were cultured in the conventional incubator, and cells in ischemia reperfusion group were cultured in hypoxia incubator and conventional incubator alternatively to simulate IRI of skeletal muscle cells. After 4 hours of incubation in hypoxic incubator, L6 rat myoblasts in bilobalide group were replaced with medium containing 20 μmol/L bilobalide, and then put into conventional incubator for further culture. CCK-8 assay was used to test cell viability 48 hours later. Related test kits were used to examine the levels of lactate dehydrogenase (LDH), superoxide dismutase (SOD), xanthine oxidase (XOD), malondialdehyde (MDA) and intracellular calcium.Results:Compared with ischemia reperfusion group [(62.2±6.8)%], the viability of myoblasts was increased in bilobalide group [(86.5±5.6)%] ( P<0.05). Compared with ischemia reperfusion group [(265.3±35.2)U/mg], the level of LDH in myoblasts was decreased in bilobalide group [(125.4±16.9)U/mg] ( P<0.05). Compared with ischemia reperfusion group [(68.6±10.7)U/mg], the level of SOD in myoblasts was increased in bilobalide group [(98.5±8.4)U/mg] ( P<0.05). Compared with ischemia reperfusion group [(224.7±65.8)U/mg], the level of XOD in myoblasts was decreased in bilobalide group [(105.9±58.9)U/mg] ( P<0.05). Compared with ischemia reperfusion group [(198.2±35.7)U/mg], the level of MDA in myoblasts was decreased in bilobalide group [(100.4±25.3)U/mg] ( P<0.05). Compared with ischemia reperfusion group (2.5±0.3), the intracellular Ca 2+ concentration in cell supernatant was decreased in bilobalide group (1.6±0.3) ( P<0.05). But all the indexes tested above did not return to the level in control group ( P<0.05). Conclusion:Bilobalide can protect skeletal muscle cells from IRI by inhibiting oxidative stress reaction and calcium overload.

Based on the traditional medical theory,the theory of"ear-brain-liver-spleen correlation"was proposed by linking the ear with the brain,liver and spleen.Then,by combining the Chinese medical etiology of Functional Dyspepsia(FD)and the corresponding modern medical mechanism,we realized that the close connection between the ear,brain,liver and spleen is the theoretical basis for treating FD from the ear.In recent years,a new type of vagus nerve stimulation therapy,auricular concha eletro-acupuncture(ACEA),has been developed to treat FD by regulating the liver and spleen through the regulation of the brain,relieving liver depression and strengthening spleen and qi,thus treating FD.In terms of modern medicine,this is related to its ability to reduce anxiety and depression,reduce pain perception,enhance gastrointestinal motility and reduce central and peripheral inflammation by regulating the activity of the corresponding brain functional areas.By exploring the application of auricular concha eletro-acupuncture in FD on the basis of the"ear-brain-liver-spleen correlation",we will better understand the unique role of auricular stimulation in regulating the brain and the blood of the liver and spleen,and promote the inheritance,innovation and development of TCM theory.
