??OBJECTIVE To study the blood enriching effect and mechanism of Jiuweiejiao ointment on mouse model of blood deficiency syndrome.METHODS Blood deficiency syndrome model was established with cyclophosphamide(CTX) and acetylphenylhydrazine(APH). Total of 60 ICR mice were divided into normal group, model group, Siwu granule group, Jiuweiejiao ointment high-dose, medium-dose and low-dose group (15.6, 7.8, 3.9 g??kg^-1). Each group mouse were treated with the respective drug through intragastrical administration once a day for consecutive 14 d. The levels of red blood cells (RBC), leukocytes (WBC), hemoglobin (HGB) level in blood of mice were detected by blood analyzer; the histopathological changes of bone marrow were determined by HE staining; the levels of erythropoietin (EPO), interleukin-3 (IL-3), tumor necrosis factor-?? (TNF-??), granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony stimulating factor (GM-CSF) in serum were measured by enzyme linked immunosorbent assay (ELISA) method; the expression level of EPO protein in kidney tissue, G-CSF and GM-CSF protein in bone marrow tissue were detected by Western-blot method.RESULTS Compared with model group, Jiuweiejiao ointment could significantly increase the levels of RBC, WBC and HGB in blood of mice, markedly improve bone marrow hyperplasia, reduce the non-hematopoietic tissue and adipocytes, obviously repaire the hematopoietic tissue structure; significantly decrease the level of TNF-?? and increase the level of EPO, IL-3, G-CSF and GM-CSF in serum. In addition, Jiuweiejiao ointment could also obviously increase the expression of EPO protein in kidney tissue and G-CSF, GM-CSF protein in bone marrow tissue compared with that in model group.CONCLUSION Jiuweiejiao ointment has obvious blood enriching effects, which may be related with promoting the secretion of hematopoietic growth factors and reducing the inhibition of hematopoietic function by negative hematopoietic factor.

??OBJECTIVE To investigate the anti-depressant effect of schisandrin A in rats with depression caused by chronic unpredictable mild stress(CUMS)as well as the relevant mechanism. METHODS The depression-like rat model using CUMS was established. Rats were randomly divided into control, CUMS model, CUMS+fluoxetine (10 mg??kg^-1)and CUMS + schisandrin A (25, 50, 100 mg??kg^-1)groups. Drugs or vehicle were administrated after stress procedures for 21 d. Open-field test (OFT), sucrose preference tests (SPT)and forced swim test (FST)were used to evaluate the anti-depressant effects of schisandrin A. The reactive oxygen species (ROS)and prostaglandin E₂ (PGE₂) level as well as superoxide dismutase (SOD) and catalase (CAT)activities in hippocampus were determined by ELISA methods. IL-1??, TNF-??, and IL-10 expression were measured by real time qPCR and Western blot analysis. RESULTS Behavioral test indicated that crossing score and rearing score in OFT and sucrose preference index in SPT of model group were significantly lower than control group (P<0.01), while immobility time in FST was significantly increased (P<0.01). Compared with those in control group, the ROS and PGE₂ level increased significantly (P<0.01), SOD and CAT activities decreased significantly (P< 0.01),the mRNA and protein level of IL-1??, TNF-??, and IL-10 were increased significantly (P<0.05 or P<0.01)in rats of CUMS. CONCLUSION Schisandrin A and fluoxetine could ameliorate those changes induced by CUMS. Schisandrin A could improve the depression-like behaviors of rats induced by CUMS, of which the mechanism might involve the antioxidant and anti-inflammatory effects.

??OBJECTIVE To investigate the protective effect and possible mechanism of schisanhenol(Sal) in SH-SY5Y cell induced by H₂O₂. METHODS SH-SY5Y cells were treated with Sal (1,10 and 50 ??mol??L^-1) for 4 h and then exposed to H₂O₂ 100 ??mol??L^-1 for 24 h. Cell viability was measured by MTT assay. The expressions of silent information regulator 1(SIRT1), PGC-1?? and p-tau (S396) protein were detected using Western blotting. RESULTS MTT results showed that Sal significantly increased the survival rate of SH-SY5Y cell damaged by H₂O₂. Western blotting analysis showed that H₂O₂ reduced the expressions of SIRT1 and PGC-1?? in SH-SY5Y cells. However, tau protein content was increased by H₂O₂ at p-tau(S396) sites. Sal treatment significantly increased the levels of SIRT1 and PGC-1?? and decreased p-tau(S396) level induced by H₂O₂ in SH-SY5Y cells. CONCLUSION These results suggest that Sal has a protective effect on H₂O₂ damaged SH-SY5Y cells, which is related to up regulating the expressions of SIRT1 and PGC-1?? protein and decreasing the phosphorylation of tau protein.

??OBJECTIVE To establish an HPLC-TQ-MS/MS assay for simultaneous determination of berberine, plantamajoside, saikosaponin a, tetrahydropalmatine, paeoniflorin and amygdalin in rat plasma and investigate the pharmacokinetics of Jiawei Baiteng extracts in rats. METHODS The separation was achieved on an Agilent Poroshell 120 EC-C₁₈ column(3.0 mm??100 mm,2.7 ??m) at 35 ??. The mobile phase was consisted of 0.05% formic acid aqueous solution and acetonitrile containing 0.05% formic acid, eluting with a gradient procedure. Mass spectrometry was performed in the multiple reaction monitoring (MRM) mode, with programmed ionization modes witching and time segment scanning. The ion reactions for quantification were as follows: m/z 335.9??m/z 319.9(berberine, ESI⁺), m/z 639.1??m/z 160.9(plantamajoside, ESI^-),m/z 779.3??m/z 617.4(saikosaponin a, ESI^-),m/z 356.0??m/z 192.0(tetrahydropalmatine,ESI⁺),m/z 449.1??m/z 121.1(paeoniflorin, ESI^-),m/z 456.1??m/z 323.1(amygdalin, ESI^-),m/z 323.9??m/z 126.9(gliclazide, internal standard, ESI⁺) and m/z 321.9??m/z 170.1 (gliclazide, internal standard, ESI^-). Blood samples were collected in heparinized tubes via the retinal venous plexus from each rat after a single oral dose of Jiawei Baiteng extracts(3.1 g??kg^-1). The plasma samples were pretreated by methanol precipitation to remove protein components, and then analyzed by HPLC-TQ-MS/MS. The pharmacokinetic parameters of the bioactive components of Jiawei Baitengex tracts in rats were calculated by DAS (Drug and Statistics for Windows) software(Version 2.0). RESULTS The methodological test showed that the linear concentration ranges of berberine, plantamajoside, saikosaponin a, tetrahydropalmatine, paeoniflorin and amygdalin were 0.59-292.50, 0.68-168.75, 6.05-1 512.50, 0.68-337.50, 6.70-1 675.00 and 5.60-1 400.00 ng??mL^-1, respectively. The limits of quantification (LOQs) of the six analytes were 0.59,0.68,6.05,0.68,6.70 and 5.60 ng??mL^-1, respectively. The HPLC-TQ-MS/MS method was also validated with good precision, recovery and stability, which conformed to the analytical standards of biological samples. CONCLUSION The established method is proved to be sensitive, simple and reliable, which is suitable for the pharmacokinetic study of Jiawei Baiteng extracts.

??OBJECTIVE To investigate the synergetic effect of schisandrin B and liposomes on overcoming multidrug resistance(MDR). METHODS Co-delivery of doxorubicin and schisandrin B by liposome(DS-L) were prepared, and doxorubicin solution(F-DOX), schisandrin B and doxorubicin mixture(Sch B+DOX), doxorubicin liposomes(D-L), doxorubicin liposomes and schisandrin B mixture(D-L+Sch B), verapamil and doxorubicin mixture(Ver+DOX) were also prepared as the control. The MTT test were measured, and the amount of doxorubicin in the K562/DOX cells at different time were determined, and time course of uptake and efflux were drawn. RESULTS The MTT test shows that the resistance factor(RF) of group DS-L were 1.68, 14.52 and 1.42 times of group Sch B+DOX, group D-L and group D-L+Sch B respectively. The uptake test shows that amount of doxorubicin of K562/DOX cells in group DS-L was 1.30 and 1.21 times of that in group D-L and group Sch B+DOX respectively. And the efflux test shows DS-L could delay doxorubicin efflux from K562/DOX cells. CONCLUSION The co-delivery of chemotherapeutics and P-gp inhibitors schisandrin B by liposome is a promising approach to overcome MDR. And there is a synergistic effect between liposome and schisandrin B to overcome MDR.
