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.

To prepare recombinant human retinol binding protein 4 (RBP4) by using the baculovirus expression system and to detect its immunogenicity, the fusion DNA fragment of secretory signal peptide SS64 and human RBP4 gene was subcloned into a baculovirus transfer vector pFastBac-dual(pFBd), and the corresponding recombinant transfer plasmid was transformed into E. coli strain DH10bac, after transposition recombinant shuttle bacmid was screened out. The logarithmic phase Sf9 cells were transfected with the recombinant bacmid and then the recombinant baculovirus containing hRBP4 expression box were generated. After amplification of recombinant baculovirus, the recombinant baculovirus seeds were obtained. To express human RBP4, logarithmic phase Sf9 cells were infected with the virus seeds and SDS-PAGE and Western blotting were used to detect and identify the expression. Finally, to prepare a batch of RBP4 protein, logarithmic phase Sf9 cells in suspension culture were infected with recombinant baculovirus seeds and the supernatant was harvested after 120 hours post-infection for purification. Finally for preparation of polyclonal antibody and evaluation of immunogenicity, the recombinant hRBP4 from insect cells and from E. coli were immunized rabbits. Restriction enzyme digestion and sequencing confirmed that the recombinant baculovirus transfer plasmid was constructed correctly, and subsequently recombinant RBP4-bacmid was generated successfully. SDS-PAGE and Western blotting analysis suggested that human RBP4 protein was highly expressed in Sf9 cells with the molecular weight of approximately 23 kDa. The recombinant RBP4 protein could be secreted into the medium efficiently, and the expression level was calculated amount of 100 mg/L. Finally the rabbit antiserum was harvested after recombinant RBP4 immunization, therein the titer of antiserum against baculovirus recombinant RBP4 is 1:100 000 whereas the titer of antiserum against E. coli recombinant RBP4 is only 1:10 000. Overall, human RBP4 was high efficiently expressed successfully with good antigenicity in baculovirus system, and high affinity antiserum was obtained. A solid foundation was laid for the next step of the preparation of human serum RBP4 detection kit.

Tumor chemoprevention and treatment are two approaches aimed at improving the survival of patients with cancers. An ideal anti-tumor drug is that which not only kills tumor cells but also alleviates tumor-causing risk factors, such as precancerous lesions, and prevents tumor recurrence. Chinese herbal monomers are considered to be ideal treatment agents due to their multi-target effects. Astragaloside has been shown to possess tumor chemoprevention, direct anti-tumor, and chemotherapeutic drug sensitization effects. In this paper, we review the effects of astragaloside on tumor prevention and treatment and provide directions for further research.

ObjectiveTo explore the efficacy and mechanism of Danshen Zexie decoction in treating the rats with metabolic-associated fatty liver disease (MAFLD). MethodSixty male SD rats were randomized into control group, model group, essentiale (polyene phosphatidylcholine capsules, 0.144 g·kg-1) group, and low-, medium-, and high-dose Danshen Zexie decoction (1.16, 2.32, and 4.64 g·kg-1, respectively) groups. The rat model of MAFLD was established with high fat diet, and 8-week therapy started at the induction of MAFLD. The serum levels of total cholesterol (TC), triglyceride (TG), alanine aminotransferase (ALT), and aspartate aminotransferase (AST), as well as the liver levels of TC, TG, free fatty acid (FFA), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA), were measured. The pathological changes of liver were observed by hematoxylin-eosin (HE) staining and oil red O staining, and the steatosis score and oil red O staining area were calculated. The level of reactive oxygen species (ROS) in the liver was detected by immunofluorescence. The protein levels of adenosine monophosphate-activated protein kinase (AMPK), p-AMPK, nuclear factor E2-related factor 2 (Nrf2), glutamate-cysteine ligase catalytic subunit (GCLC), glutamate-cysteine ligase modifier subunit (GCLM), and nicotinamide adenine dinucleotide phosphate: quinine oxidoreductase (NQO1) in the liver were determined by Western blot. ResultCompared with control group, the modeling of MAFLD elevated the levels of TC, TG, ALT, and AST in the serum and TC, TG, FFA, MDA, and ROS in the liver (P<0.01), lowered the levels of SOD and GSH and down-regulated the protein levels of phosphorylation(p)-AMPK, Nrf2, GCLC, GCLM, and NQO1 in the liver (P<0.05, P<0.01). Further, a large number of lipid droplet vacuoles and balloon-like lesions appeared in the hepatocytes, and the steatosis score and oil red O staining area increased in the model group (P<0.01). Compared with model group, Danshen Zexie decoction lowered the levels of TC, TG, ALT, and AST in the serum and TC, TG, FFA, MDA, and ROS in the liver (P<0.01), increased the levels of SOD and GSH and up-regulated the protein levels of p-AMPK, Nrf2, GCLC, GCLM, and NQO1 in the liver (P<0.05, P<0.01). Moreover, the decoction alleviated the degree of liver steatosis (P<0.05, P<0.01). ConclusionDanshen Zexie decoction protects against MAFLD by activating AMPK/Nrf2 signaling pathway and suppressing oxidative stress.
