China Journal of Chinese Materia Medica 2015;40(9):1783-1786
An HPLC method was established to simultaneously determine the five sesquiterpene lactones, carabrone, carabrol, 2-desoxy-4-epi-pulchellin, telekinand 11(13)-dehydroivaxillin in Carpesium abrotanoides. Samples were analyzed on a kromasil C18 column (4.6 mm x 250 mm, 5 µm); mobile phase: A was acetonitrile, B was water, with gradient elution; flow speed: 1.0 mL · min(-1); detection was carried out using a photodiode array detector at 211 nm; temperatureof column: 30 °C. The five sesquiterpene lactones were well separated with good linear correlations in the range of 0.270-2.700 (r = 0.999 7 ), 1.336-13.360 (r = 0.999 6), 0.258-2.580 (r = 0.999 7), 0.238-2.380 (r = 0.999 9), 0.490-4.900 µg (r = 0.999 9) for carabrone, carabrol, 2-desoxy-4-epi-pulchellin, telekin and 11 (13) -dehydroivaxillin. The average recoveries of these five sesquiterpene lactoneswere 96.78%-98.41% (RSD 1.3%-2.9%). The method was simple, repeatable and stable, which could be used for quality control of C. abrotanoide.

ObjectiveTo observe the influence of rehabilitation training on heart rate of stroke patients in the early stage.MethodsThe heart rate (HR) of 30 patients within one week after the onset of stroke was evaluated by FUKUDA DS 880A teleelectrocardiograph and the rating of perceived exertion (RPE) was collected during practicing bridging, rolling and moving the arms.ResultsThe HR of 30 patients was only increased 7.57, 6.23 and 6.57 beats per minute during practicing bridging, rolling and moving the arms. RPE of all patients was less than 11.ConclusionAppropriate rehabilitation training is safety and unable to increase the loading of heart in the early stage after the onset of stroke.

To study the chemical constituents from Zanthoxylum simulans and their anti-inflammatory activity. The constituents of Z. simulans were isolated and purified using various column chromatographies. Their chemical structures were elucidated using extensive spectroscopic methods. The compounds were assayed inhibitory activity against NO production in LPS stimulated RAW 264.7 cells. Four compounds were obtained from the ethanol extract of Z. simulans and determined to be isozanthpodocarpin B(1), kobusin (2), (+)-fargesin (3), and epieudesmin (4). Compound 1 exhibited NO production inhibitory effect with IC50 value of 14.49 µmol · L(-1). Compound 1 is a new dimeric lignan and may be serve as potential anti-inflammatory agent in the future.

italic>γ-Aminobutyric acid (GABA) is a crucial inhibitory neurotransmitter found in various cells in the human body. While the GABAergic system is typically associated with the nervous system, recent research has revealed that immune cells and tumor cells also express components of this system. In the tumor microenvironment (TME), GABA is secreted to act extracellularly on other cells. GABA is metabolized

Objective To analyze the clinical features of infantile cytomegalovirus(CMV) hepatitis with cholestasis and investigate intrahepatic cholestasis due to hepatocytic impairment caused by CMV infection.Methods Forty-seven children with CMV cholestatic he-patitis were divided into 2 groups according to the level of total bilirubin(TB):22 cases with serum TB lower than 136.8 ?mol/L(groupⅠ),and 25 cases with serum TB higher than 136.8 ?mol/L(groupⅡ).All children were treated with both gangciclovir and routine met-hods,and serum biochemistry were checked before and after treatment.SPSS 13.0 software was used to analyze the data.Results Forty-seven cases of infantile CMV cholestatic hepatitis had different degrees of jaundice,hepatosplenomegaly and abnormal liver functions.The differences of serum ALT and AST between the 2 groups had statistical significance,the levels of serum gamma glutamy transferase(GGT) and alkaline phosphatase(ALP) were lightly higher in groupⅡcompared with those in groupⅠ,but there were no statistical significance.TB,direct bilirubin(DB),ALT and AST were decreased in the 2 groups after treatment,GGT and ALP hadn′t decreased significantly after treatment.Conclusions CMV infection can injure hepatocytes and epithelials on each grade of bile duct,thus CMV hepatitis causes intrahepatic cholestasis.Cholestasis due to hepatocytic impairment deserves emphasis and intervention should be done as early as possible.Gangciclovir therapy for CMV infection manifest effective and safe in short-term.

To study the contribution of T cell subsets in the pathogenesis of Murine hepatitis virus Type3 (MHV-3) induced chronic viral hepatitis in C3H/Hej mice, ninety C3H/Hej mice were chosen to individually receive 10 plaque forming units (PFU) of MHV-3 intraperitoneally. The changes of virus titer and pathology in liver tissue were examined by standard plaque assay and by the hematoxylin/eosin (HE) staining method from 2 days post MHV-3 infection. The ratios of T cell subsets including CD3+CD4+CD8-, CD3+CD4-CD8+, CD3+CD4-CD8-, CD3+CD4+CD25+, CD3+CD4+CD25- and CD3+CD4-CD25+ T lymphocyte of total T lymphocytes in blood, spleen and liver were examined at 0, 2, 4, 6,8, 10, 12, 15, 20, 25, 30, 40 days post MHV-3 infection by flow cytosorting. We observed that the virus titer raised and showed persistent virus duplications and inflammatory changes in the livers of C3H/Hej mice from 2 days post MHV-3 infection. The double negative T cell (DN Treg cell) and CD4+CD25+ T cell ratios increased significantly from 2 days post MHV-3 infection in C3H/Hej mice, and CD3+CD4+CD8-, CD3+CD4-CD8+, CD3+CD4+CD25- and CD3+CD4-CD25+ T cell ratios decreased accordingly. In conclusion, the changes of virus titer and pathology in the livers of C3H/Hej mice post MHV-3 suggest their contribution to viral persistence. Further characterizations of DN Treg cells are that infection indicates that MHV-3 could induce the chronic inflammation in livers of C3H/Hej mice.The increase of the DN Treg cell and CD4+CD25+ T cell ratios in C3H/Hej mice post MHV-3 infection suggests that DN Treg cells and CD4+CD25+ T cells may both have important suppressive immunomodulation functions in the development of chronic viral hepatitis and have important roles in the virus persistent infection. Further characterizations of DNT cell and CD4+CD25+ T cell are under investigation.
