OBJECTIVEEffects of ginsenoside Rb1, Rg1 and Re on neurotrophic factor signal transduction pathway using liposome-mediated transfection of eukaryotic cells approach.
METHODThe injury model was established by treating SH-SY5Y cells with 0.6 mmol x L(-1) of corticosterone (CORT) by 24 h. SH-SY5Y cell were pretreated with CORT for 30 min followed by co-treated with 120,60 and 20 micromol x L(-1) of Rb1, 120, 80 and 40 micromol x L(-1) of Rg1 and 120, 80 and 40 micromol x L(-1) of Re for 24 h. Cells viability was determined by Cell Counting Kit (CCK) assay. CREB expressing Luciferase reporter gene was constructed and transfected with plasmid containing hRaf, hcAMP, hAkt, hCaMK gene into human embryonic kidney (HEK293) cells using liposornal transfection reagent lipofection 2000. The expression of CREB before and after it addion of Rb1, Rg1 and Re was examined by Luc assay system and Western blotting.
RESULTCompared with normal control group, CORT significantly decreased the viability of SH-SY5Y cells to 67.21% (P < 0.01). CCK results show that Rb1 (60 micromol x L(-1)), Rg1 (80 micromol x L(-1)) and Re (80 micromol x L(-1)) on SH-SY5Y cells have significant protective effect (P < 0.01). Lucassay and Western blotting results show that the gene and protein levels of CREB increased significantly through the pathway of Raf and Akt with Rb1 and Rg1 (P < 0.01), Re can increase significantly the gene and protein levels of CREB through the pathway of Raf and CaMK II.
CONCLUSIONRb1, Rg1 and Re protects SH-SY5Y cells from CORT-induced damage and the neuroprotective mechanism may be associated with the Raf-CREB, Akt-CREB and CaMK II -CREB pathways.

OBJECTIVETo observe therapeutic effect and safety of acupuncture at the five-zangshu for treatment of perimenopausal syndrome (PMS).
METHODSForty cases of PMS were randomly divided into a treatment group and a control group, 20 cases in each group. The treatment group were treated with acupuncture at the five-zangshu and the control group with oral administration of Premarin tablets. The therapeutic effects and changes of Kupperman scores, and serum estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH) levels before and after treatment were observed.
RESULTSThe total effective rate was 90. 0% in the treatment group which was better than 65.0% in the control group (P<0. 05). After treatment, serum E2 level significantly increased (P<0.01), with a significant difference between the two groups (P<0.05), and with a significant difference between the two groups in Kupperman symptom score index (MI) after treatment (P<0.05).
CONCLUSIONTherapeutic effect of acupuncture at the five-zangshu is better than that of Premarin for treatment of perimenopausal syndrome.

OBJECTIVETo observe the expression of phospholipid scramblase 1 (PLSCR1) in matrine (MAT) induced differentiation of all-trans retinoic acid (ATRA) resistant acute promyelocytic leukemia (APL) cells, and to explore its correlation to cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signal pathway.
METHODSNB4 (an APL cell line sensitive to ATRA) and NB4-R1 (a resistant strain of ATRA) were observed as subjects in this study. Effects of combined treatment of 0.1 mmol/L MAT and 1 [mol/L ATRA on the differentiation of two cell lines were detected using nitroblue tetrazolium (NBT) reduction test and flow cytometry (CD11b). Expressions of PML/RARot and PLSCR1 protein/gene were detected using Western blot and Real-time fluorescence quantitative PCR assay. Meanwhile, H89, PKA antagonist, was used to observe cell differentiation antigen and changes of aforesaid proteins and genes.
RESULTSMAT combined ATRA could significantly elevate positive rates of NBT and CD11 b in NB4-R1 cells, and significantly down-regulate the expression of PML/RARapha-fusion protein/gene (P < 0.05, P < 0.01). ATRA used alone could obviously enhance the expression of PLSCRI in NB4 cells at protein and mRNA levels (P < 0.01). But the expression of PLSCR1 was up-regulated in NB4-R1 cells, but with statistical.difference only at the protein level (P <0. 01). In combination of MAT, PLSCR1 protein expression was further elevated in the two cell lines (P < 0.01). Besides, there was statistical difference in mRNA expressions in NB4-R1 cells (P < 0.05). All these actions could be reversed by treatment of 10 micromol/L H89 (P < 0.05, P < 0.01).
CONCLUSIONMAT combined ATRA could significantly induce the differentiation of NB4-R1 cells, and inhibit the expression of PML/RARalpha fusion gene/protein, which might be associated with up-regulating PLSCR1 expression.

OBJECTIVETo compare the effect of reinforcing Shen method (RSM) and activating blood method (ABM) in treating osteoarthritis (OA) at the molecular level.
METHODSThe physical and chemical characteristics of components from respective recipes of RSM and ABM, and network features of component-target interaction network were analyzed by computer simulation methods including chemical space, molecular docking, and biological network, etc.
RESULTSThe chemical components of RSM and ABM were scarcely scattered with larger overlapping. Among established networks, the distribution of network features was partially similar in RSM and ABM. The average target number correlated with each component was 1.86 in RSM and 2.11 in ABM respectively. Each average target number was respectively correlated with 4.46 compounds and 3.93 compounds, reflecting multi-component and multi-target actions.
CONCLUSIONComputer simulation could intuitively trace out similarities and differences of two different methods and their interaction with targets, which revealed that the compatibility of RSM and ABM could have broader protein targets and potential synergism at the molecular level.
