Objective To analysis the quality of life of patients with active ankylosing spondylitis (AS).Methods The quality of life was assessed in 52 patients with active AS using SF-36 and was compared with the general population.The correlation between the quality of life and the clinical measures of disease,in- cluding the Bath AS disease activity index(BASDAI),Bath AS functional index(BASFI),Bath AS metrology index(BASMI),patient's global assessment(PGA),spinal inflammation,total back pain,nocturnal back pain, and enthesis index(EI),were determined.Results The patients with active AS reported significant decreased scores on all dimensions of SF-36.The score of physical health components was poorer than that of mental health components.BASFI was the strongest factor correlated with the score of SF-36,followed by BASDAI and PGA.BASMI and total back pain were correlated with three dimensions only.In multivariate regression analysis,BASFI showed relative closer relationship to the qulity of life with active AS than other clinical mea- sures of disease and it accounted for 50.3%,35.2% and 47.9% of the variance in the physical health compo- nents,the mental health components and the overall score of SF-36,respectively.Conclusion The quality of life in patients with active AS is significantly declined compared with general population.The physical aspects seem to be more severely affected.Functional status of the patients with active AS are correlated with the quality of life closely.

OBJECTIVETo study the effect of total saponins of Panax ginseng (TSPG) on the expression of granulocytemacrophage colony-stimulating factor (GM-CSF) from human endothelial cells and monocytes and the relationship between TSPG and human granulocytopoiesis and monocytopoiesis modulation.

METHODSAdopting the hematopoietic progenitor cells culture in vitro, hematopoietic growth factor biological assay, immunocytochemistry and nucleic acid in situ hybridization, the GM-CSF expression in the endothelial cells and monocytes were detected.

RESULTSThe conditioned cultural media of endothelial and monocytes induced and prepared by TSPG, could significantly promote the proliferation and differentiation of human colony forming unit-granulocyte macrophage (CFU-GM), and enhance the protein and mRNA expression of GM-CSF in endothelial cells and monocytes.

CONCLUSIONTSPG could possibly through direct or indirect route, promote hematopoietic, induce endothelial cells and monocytes in the microenvironment to synthetize and secrete GM-CSF, so as to further promote the proliferation and differentiation of human CFU-GM.

A reliable method for simultaneous determinition of eleven representative components (neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, shanzhiside, geniposidic acid, genipin-1-β-D-gentiobioside, geniposide and secoxyloganin) in combination of chromatographic fingerpint analysis for Reduning injection was developed by ultra high-performance liquid chromatography (UPLC). The method was performed on an Agilent ZORBAX SB-C18 anlytical column (3. 0 mm x 100 mm, 1. 8 µm) with a guard column of Agilent UPLC Guard ZORBAX SB-C18 (3.0 mm x 5 mm) at the column temperature of 30 °C. The gradient mobile phase consisted of acetonitrile (A)-0. 1% phosphoric acid (B) with a flow rate of 0. 4 mL . min-1. The injection volumn was 2 µL. The detection wavelengths were set at 324 nm and 238 nm for quantit tive analysis and 225 nm for fingerpint chromatography. Neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, shanzhiside, geniposidic acid, genipin-1-β-D-gentiobioside, geniposide and secoxyloganin were baseline seperated with good linearity relationships (r >0. 999) between concentration and peak areas over the linear ranges. The average recoverys of the investigated compounds were 103.5%, 100. 2%, 103. 3%, 102. 8%, 101. 3%, 102. 8%, 97. 36%, 99. 62%, 98. 16%, 102. 8%, 99. 27%, respectively. Reduning injection of forty-five batches was analyzed by UPLC finge print chromatography. Thirty batches were selected to generate the reference fringerprint chromatography with fourteen common peaks. The similarity values between the reference fringerprint chromatography and the remaining fifteen batches were higher than 0. 99. The developed method was fast, accurate and sensitive. It could be used as a reference for the quality control of multiple components determination and fingerprint chromatography for Reduning injection in future.

OBJECTIVETo purify caffeic acid tetramer (CAT) with macroporous resin on the basis of its fundamental physicochemical stability research.

METHODThe changes of CAT content were compared by HPLC method before and after the purification process, or while other conditions were altered.

RESULTLK001 was the best one among 7 kinds of macroporous resin in regard of purifying ability. The optimum absorbing technology was the solution concentration at 10 g x L(-1), pH at 4.5, and the flow rate at 3 BV x h(-1). The best eluting technology was 45% ethanol as eluting agent, pH at 5.0, eluting volume at 50 mL after applying super-purified water and 20% ethanol. The yield of product was 3. 6 percent, and the active compound CAT was 58 percent in the product.

CONCLUSIONMacroporous resin LK001 is effective in enriching CAT from the crude extracts, thus this method of purification is advisable.

To describe the effects of endogenous testosterone levels on the visuospatial ability.Thevisuospatial ability,testosteronewere included as the key words,retrieving 46 papers in the database.35 relevant papers have been reviewed in the paper,as the results,we have found that the visuospatial ability of male was better than female.The performances of the visuospatial tasks in males were associated with the lev-els of endogenous testosterone,and the effects comprised two aspects:the organizational function and activa-tional function of the testosterone.The latter have received more attention from researchers.Until now,most studies of activational effects of testosterone on visuospatial ability remained on the level of behavioral re-search.The mental rotation task,navigation task and virtual reality scenes tasks were implied in these stud-ies.A nonlinear relationship has aroused a great controversy.Latest research suggests that further investiga-tion of the neural mechanisms related to visual-spatial ability is needed,using ERP and MRI techniques,to assess the relationship of endogenous testosterone levels with the relevant neural basis of visuospatial ability.

To investigate the effects of total saponins of panax ginseng (TSPG) in combination with hematopoietic growth factors (HGF) on proliferation and differentiation of CD34(+) cells ex vivo, the purified CD34(+) cells from cord blood and bone marrow were expanded by various concentrations of TSPG with combination of cytokines in liquid culture systems and the expanded cell number, CD34(+) cell number, CD33(+) cell ratio, the numbers of total CFC and hematopoietic progenitor cell number were detected. The results showed that TSPG (10 - 70 microg/ml) could raise the expanded cell number, CD34(+) cell number, and the numbers of total CFC, TSPG 50 microg/ml was identified as the most potent stimulating concentration, and increased total nucleated cells to (2470.5 +/- 79.96) x 10(3), CFC to (53.96 +/- 4.286) x 100% and CD34(+) cells to (21.86 +/- 3.094) x 100%; TSPG (10 - 50 microg/ml) could raise the colony formation rate of CFU-GM, TSPG (20 microg/ml) induced the best effect on granulocytopoietic differentiation committed of CD34(+) cells. It is concluded that the optimal concentration of TSPG can promote CD34(+) cells to proliferate and differentiate by cooperating with hematopoietic growth factors.

OBJECTIVETo observe the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) in the unstable plaque of patients with acute coronary syndrome (ACS), and the impact of leukotriene B4 (LTB4) on the EMMPRIN expression in macrophages.

METHODSThe EMMPRIN expression was detected by immunohistochemistry in 11 unstable plaques from patients with ACS. Protein expression of EMMPRIN was evaluated by Western blot on macrophages differentiated from THP-1 which were stimulated with LTB4 in the absence or presence of LTB4 antagonist U75302. There are 8 study groups: 1-THP-1, 2-8-the macrophages derived from THP-1, 2-6-macrophages were stimulated by LTB4 (0, 10(-10), 10(-9), 10(-8) and 10(-7) mol/L) for 24 h, 7-8-the macrophages were pretreated by 10(-6) mol/L or 10(-7) mol/L U75302 2 h before the LTB4 (10(-7) mol/L) stimulation.

RESULTSAbundant EMMPRIN expression was detected in macrophages and smooth muscle cells of unstable plaques from ACS patients. As to the THP-1 derived macrophages, EMMPRIN expression was significantly upregulated in a concentration-dependent manner in LTB4 stimulated groups, which was significantly higher in group 3-6 than in the THP-1 group (group 1) and macrophages group (group 2) (all P < 0.05) and pretreatment with U75302 significantly reduced the LTB4 induced upregulation of EMMPRIN in a dose-dependent manner (P < 0.05).

CONCLUSIONEMMPRIN expression is enhanced in macrophages and smooth muscle cells on unstable coronary artery plaques from ACS patients. LTB4 could stimulate EMMPRIN expression on THP-1 derived macrophages suggesting that LTB4 and EMMPRIN might be both involved in the formation and progression of unstable plaques, future studies are warranted to explore if LTB4 and EMMPRIN antagonists are effective or not for treating patients with ACS.

OBJECTIVETo investigate the effects of total saponins of panax ginseng (TSPG) on proliferation and differentiation of human embryonic neural stem cell (NSC) into dopaminergic neuron.

METHODIsolation, cultivation and identification of human embryonic NSC from cerebral cortex of 7-12 week abortus. By using flow cytometry and MTT assay, the effects of various concentration of TSPG and TSPG cooperating with cytokines( EGF, bFGF) in NSC culture media for 3 days on proliferation of human embryonic NSC has studied. By employing immunocytochemistry assay of the expression of tyrosine hydroxylase (TH), the effect of different dilution of TSPG and TSPG cooperating with IL-1 on induced differentiation of human embryonic NSC into dopaminergic neuron has researched.

RESULTTSPG can significantly promote the proliferation of NSC. When TSPG cooperating with EGF and bFGF, the proliferation of NSC is much stronger than that of only using FGF and bFGF. TSPG also induces NSC to differentiate into dopaminergic neuron, especially when TSPG is cooperating with IL-1.

CONCLUSIONTSPG can not only obviously accelerate the proliferation of NSC, but also significantly induce differentiation of NSC into dopaminergic neuron.
