Objective: To observe the effect of Liuwei Dihuang decoction on brain development of intrauterine growth retardation rats,and to demonstrate the relationship between brain and kidney in TCM.Methods: Animals were divided into 4 groups at random: normal group,model group,Huangqi(HQ) and Liuwei Dihuang(LD) treated groups.The IUGR model was established by passive smoking.On the 19th day of pregnancy,all rats were killed;the total numbers of embryos,the lively,dead and absorbed embryos were counted.The body and brain weight of lively embryos were scaled respectively,then microstructure and apoptosis in brain were observed.Results: Passive smoking can result in the number of dead and absorbed embryos increases.Compared with normal group,the number of apoptotic cells of model group increased.Compared with model group,in Huangqi and Liuwei Dihuang treated groups,the number of dead and absorbed embryos decreased apparently,body and brain weight increased obviously,the number of apoptotic cells reduced significantly(P

To evaluate the regulating effect of Buyang Huanwu decoction and its simple prescription (Naojian tablet) on CDK4/Cyclin D1 expression in hippocampus tissues of rats with cerebral ischemia, SD rats were divided into the sham-operation group, the model group, the Buyang Huanwu decoction group (ig, 3.15 g · kg⁻¹) and the simple prescription group (ig, 2.41 g · kg⁻¹). Each group was further divided into five subgroups based on time points after the administration, i. e. 1 d, 3 d, 7 d, 14 d and 28 d, respectively. CDK4/Cyclin D1 expressions of the group at different time points were examined by using immunohistochemistry and real-time qPCR. According to the results, the cerebral ischemia model group showed higher CDK4/Cyclin D1 expression than the sham-operation groups (P < 0.05), suggesting that the cell cycle signal pathway would be activated by the cerebral ischemic injury. Both Buyang Huanwu decoction and simple prescription groups showed significantly lower cyclin expression than the model group at 3 d, 7 d, 14 d, 28 d (P < 0.05), indicating both Buyang Huanwu decoction and its simple prescription could play the neuroprotective effect through the cell cycle signal pathway.

Their anti-tumor activities in vitro were measured by MTT colorimetric assay. Results Eight compounds were isolated from the roots of this plant. Conclusion The major type of chemical constituents of in Yunnan is furocoumarin. These separated compounds showed weak anti-tumor activity in vitro.

The study aims to explore the effects and mechanisms of water extract of Potentilla anserina (PA) on myelosuppression mice induced by cyclophosphamide based on metabonomics. The myelosuppressive mouse model was established by injected with cyclophosphamide and treated with water extract of PA. Thymus and spleen indexes, peripheral hemogram and bone marrow nucleated cells of each group was detected. Bone marrow pathology analysis was performed by hematoxylin-eosin staining. The levels of interleukin 3 (IL-3), interleukin 6 (IL-6), erythropoietin (EPO), granulocyte colony stimulating factor (GM-CSF), malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in serum were measured. The changes of biomarkers and related metabolic pathways were analyzed by UPLC-Q-TOF/MS-based metabonomics. Animal experiments were approved by the Animal Ethics Committee of Southwest Minzu University. The high doses of PA could significantly improve the decrease of white blood cell (WBC), red blood cell (RBC) counts and hemoglobin (HGB) levels of mice induced by cyclophosphamide (P < 0.05), and significantly increase the number of nucleated cells and the area of hematopoietic tissue in femoral bone marrow. The medium and high doses of PA could significantly improve the serum levels of SOD, CAT, MDA, IL-6 and GM-CSF (P < 0.05), and have no significant effect on the expression of IL-3 and EPO (P > 0.05). Serum metabolomics analysis showed that the aqueous extracts of PA could alleviate myrosuppression by regulating the aminoacyl-tRNA, valine, leucine and isoleucine biosynthesis mediated by 13 different metabolites such as valine, leucine, asparagine and hydroxyisohexic acid. PA improve the inhibition of hematopoietic function in myelosuppression mouse, and its mechanisms may be related to anti-oxidation and promoting the expression of hematopoietic-related cytokines and regulating the related metabolic pathways.

OBJECTIVETo study the anticancer effect in vitro and in vivo and mechanism of DHA compound.

METHODSCervical cancer cell line HeLa cells, glioma cell line U251 cells and mouse hepatoma H(22) tumor were used in this study. Transmission electron microscopy and fluorescence microscopy were used to observe the morphological changes of cell apoptosis. Western blot was used to detect the expression of caspase-3. RT-PCR was used to determine the effect on Bcl-2 and Bax mRNA transcription in U251.

RESULTSAntitumor effect was observed in vivo and in vitro. Typical morphological changes were seen in cancer cells. The level of caspase-3 was significantly increased and the content of Bcl-2 mRNA was decreased significantly, while the content of Bax mRNA was significantly increased in the U251 cells after treatment with DHA compound.

CONCLUSIONDHA compound can inhibit the growth of some types of tumors and the increase of caspase-3 and Bax mRNA and decrease of Bcl-2 mRNA may be involved in its mechanism of action.

OBJECTIVETo study the acting mechanism of Cordyceps mycelia extract (CME) for antagonizing hepatic sinusoidal capillarization (HSC) in rats with dimethylnitrosamine (DMN) induced liver cirrhosis.

METHODSRat liver cirrhosis model was established by peritoneal injection of DMN 10 mg/kg 3 times a week for 4 weeks. To rats in the CME-prevented group CME were administrated at a dose of 10 mL/kg, once a day, for 4 weeks. The observation time points were scheduled on the 3rd day (d3), and at the end of the 2nd (W2) and 4th week (W4) after modeling, and the following items were observed: hepatic ultrastructure was observed under electron microscope; expressions of CD44, von Willebrand factor (vWF) and type IV collagen (Col lV) in the liver sinusoidal walls by immunohistochemistry; matrix metalloproteinase-2 and-9 (MMP-2, MMP-9) activity under zymogram method; and serum hyaluronic acid (HA) content by radioimmunoassay.

RESULTSObservation at d3 showed MMP-2 and MMP-9 activity significantly increased, Col IV deposition and CD44 positive staining decreased, vWF positive staining increased in the liver sinusoidal walls, the fenestrae in the sinusoidal endothelial cells (SECs) decreased, and serum HA content increased (P<0.05); at W4, SECs defenestration and sub-SECs basal membrane formation were shown. In the CME-prevented group MMP-2 and MMP-9 activity significantly decreased (P<0.05); defenestration and basal membrane formation alleviated in the early stage (d3, W4); and at W2 and W4 decreases of HA content and vWF positive staining were shown, with increase of CD44 positive staining (P<0.05), more SECs fenestrae, and alleviated basal membrane formation.

CONCLUSIONSThe elevation of MMP-2 and MMP-9 activity in the early stage, which degrades the Col IV normally distributed under the sinusoidal endothelium, is an important factor for HSC formation. CME could inhibit the initiation of HSC by decreasing MMP-2 and MMP-9 activity in the early stage, and prevent its formation by decreasing SECs injury and phenotypic changes.

The fine structure of enoxaparin sodium samples with different degree of 1,6-anhydro derivatives were analyzed with polyacrylamide gel electrophoresis, high performance liquid chromatography, ultraviolet spectroscopy, infrared spectroscopy and nuclear magnetic resonance spectroscopy. A further study of anticoagulation activity of enoxaparins was performed, including those on their inhibition activities of coagulation factor Xa (FXa) and thrombin (FIIa). The results showed that the anti-FXa and -FIIa activities of enoxaparins with different degree of 1,6-anhydro derivatives (20.0%-39.7%) with similar structure characteristics, had decreasing tendency when the degree of 1,6-anhydro derivatives increased. Especially, the anti-FXa activity was sensitive to the change of the degree of 1,6-anhydro derivatives.

OBJECTIVETo study the effects of Rhaponticum uniforum polysaccharide on immune function in normal mice and the underlying mechanism.

METHODSRBC and ovalbumin were employed as antigens to be injected to mice, respectively. Three doses of R. uniforum polysaccharide (50, 100, 200 mg x kg(-1) x d(-1)) were given orally for seven days. After the secondary immunization, the level of corresponding antibody and the concentration of serum IL-2, IFN-gamma were determined.
