OBJECTIVE:To investigate the protective effect of the compatibilities of ginsenosides Rg1 and aconitine on myocar-dial cell of in vitro cultured heart failure model. METHODS:The myocardial cells of neonate rat were grouped into normal control group,model group,positive control group(Deslanoside injection,1×10-7 mol/L),ginsenosides Rg1 group(1×10-8 mol/L),acon-itine group (1 × 10-9 mol/L) or their compatibilities groups (1∶1,2∶1,1∶2,V/V). Except for normal control group,other groups were given 0.8%pentobarbital sodium to induce heart failure model of myocardial cells. After modeling,each group was given rele-vant medicine for 1 h,and then the activities of T-ATPase,Ca2+-Mg2+-ATPase,Na+-K+-ATPase in cells were all detected. The activi-ties of acyl carrier protein(ACP)and lactate dehydrogenase(LDH),and the contents of brain natriuretic party(BNP),TNF-α and total glycogen were measured in cell culture fluid. RESULTS:Compared with normal control group, T-ATPase and Ca2+-Mg2+-ATPase activities were decreased significantly in model group;meanwhile,Na+-K+-ATPase activity was increased signifi-cantly,and ACP,LDH activities and BNP content in cell culture fluid were increased significantly(P<0.05). Compared with mod-el group,the activities of T-ATPase in treatment groups were increased significantly,while the activity of LDH in cell culture fluid was decreased significantly;when the volume ratio of ginsenoside Rg1 to aconitine was 2∶1,protective effect was the strongest;the activities of Na+-K+-ATPase in aconitine group and compatibility groups were all decreased significantly,with statistical signifi-cance(P<0.05). The activities of ACP and BNP in cell culture fluid were all decreased in treatment groups,but the content of to-tal glycogen in cells and the TNF-α content of in cell culture fluid had no change (P>0.05). CONCLUSIONS:Compatibility of ginsenosides Rg1 and aconitine can improve ATPase activities and membranous permeability,regulate BNP secretion and protect myocardial cell of heart failure model,especially the compatibility of ginsenosides Rg1 to aconitine of 2∶1 ratio.

Objective To comparative analysis the rabbit VX2 tumors angiogenesis in fatty liver and normal liver,and investigate the correlation of contrast-enhanced ultrasound (CEUS) parameters and their angiogenesis.Methods Rabbit models of fatty liver and normal liver with implanted VX2 tumors were established.Two groups of hepatic backgrounds and VX2 tumors were analyzed by QontraXt quantitative software of CEUS.The expression level of tumor microvascular density (MVD) and vascular endothelial growth factor (VEGF) were detected with immunohistochemical techniques and real-time fluorescence quantitative PCR (FQ-PCR).Results ①No significant difference was found in MVD,VEGF protein and gene expression between VX2 tumors in normal liver and fatty liver.The expression of VEGF gene in fatty liver parenchyma were lower than normal liver parenchyma (P ＜0.05).②There was positive correlation between MVD and peak intensity (r =0.494,P ＜0.05; r =0.591,P ＜0.01) both in fatty liver and normal liver VX2 tumors.The expression of VEGF protein were not correlated with TIC parameters (all P ＞ 0.05).③The MVD had positive correlation with expression of VEGF protein in fatty liver and normal liver VX2 tumors (r =0.508,P ＜0.05; r =0.570,P ＜0.01).Conclusions The expression of MVD and VEGF had no significant difference between fatty liver and normal liver VX2 tumors.The peak intensity of VX2 tumors CEUS had positive correlation with MVD both in fatty liver and normal liver,which can indirectly reflect MVD expression level and help to evaluate tumor angiogenesis.
