ABSTRACT
OBJECTIVE: To study the polar chemical constituents from Prunella vulgaris L. METHODS: Silica gel, reverse-phase octadecylsilyl(ODS), Sephadex LH-20 chromatographic methods, MCI and HPLC were applied to isolate and purify compounds. MS and NMR methods were used to determine the structures of the compounds. Furthermore, the cytotoxicity of these chemical components for MCF-7, MDA-MB-231 and MCF-10A cell lines was measured by MTT method. RESULTS: A total of 12 compounds were isolated from the fruits of P. vulgaris and their structures were identified as methyl 3,4,α-trihydroxypropionate(1), danshensu(2), methyl rosmarinate(3),3,4-dihydroxybenzoic acid(4), quercetin-3-O-glycopyranoside(5), hyperoside(6), 2α,3α,19α,24-tetrahydroxylurs-12-en-28-oic acid(7), 2α, 3α, 24-trihydroxyolean-12-en-28-oic acid(8), cytidine(9), daucosterol(10), (3S,5R,10S)-7-oxo-12-methoxyabieta-8,11,13-triene-3,11,14-triol(11), and 2α,3α,24-trihydroxyolean-12,20(30)-dien-28-oic acid(12). The results of antitumor assay indicated that compound 2,3,5 and 6 significantly inhibited the activity of MCF-7, compound 3 could inhibit the activity of MDA-MB-231, but all of them also significantly inhibited the activity of normal cell lines MCF-10A. CONCLUSION: Compounds 9 and 11 are isolated from the genus of Prunella L. for the first time. Some chemical constituents form Prunella L. show certain anti-breast cancer activity.
ABSTRACT
OBJECTIVE: To evaluate the effect of Polygonatum odoratum polysaccharide(POP) on hyperthyroidism Yin-deficiency rats based on GC-MS metabolomics and explore its mechanism. METHODS: SD rats were randomly divided into control, model and POP groups. The hyperthyroidism Yin-deficiency rats were treated by intraperitoneal injection of T3 for a week. The content of T3, T4 in serum and cAMP, cGMP in plasma was determined. A GC-MS based metabolic profiling method was employed to analyze the distinctive metabolic patterns of serum in control, model and POP. Multivariate statistical analysis was applied for multivariate analysis to find potential biomarkers of Yin-deficiency by SIMCA-P 12.0 software. RESULTS: Compared with the model group, polygonatum polysaccharide can significantly reduce the content of T3, T4, cAMP, the ratio of cAMP/cGMP and increase the content of cGMP, indicating it has certain Yin-nourishing action. The PCA score plot showed metabolic profiling of control, model and POP had significant differences. Nine potential biomarkers were identified by PLS-DA and variable importance for project values(VIP) based on the metabolomics. CONCLUSION: The endogenous metabolites were changed by POP intervention significantly in Yin-deficiency rats, and the preventive role may be related to the synergism of glucose and lipid metabolism, amino acid metabolism, energy metabolism with the multi-targets, which provides a basis for further study of the mechanism of POP treatment of Yin-deficiency.
ABSTRACT
<p><b>OBJECTIVE</b>To construct and evaluate the criteria of injury based on the theoretical model that 'Injury' is the combination of 'Hurt' and 'Harm', in order to provide theoretical basis for scientific and rational research on injury in future epidemiological survey.</p><p><b>METHODS</b>The criteria of epidemiological injury was consected by analyzing documents and consulting experts, then Delphi method was used to evaluate its rationality.</p><p><b>RESULTS</b>The epidemiological definition for 'Injury'is the combination of 'Hurt' and 'Harm'. 'Hurt' means the wound in clinical medicine, while 'Harm' means the damage from the views of public health. The active coefficients of two rounds Delphi Method were both 100%. The authority coefficients of two rounds were 0.88 and 0.87, respectively. The coordination coefficients were 0.44 and 0.62 (P<0.05), respectively. After two rounds consulting, all scores of rationality for definition of 'Hurt', definition of 'Harm', 'Injury' being the combination of 'hurt' and 'harm', 'Injury' should be graded, Graded based on the 'Injured' time were above 3, and all values of CV for those index were below 0.25 except Graded based on the 'Injured' time.</p><p><b>CONCLUSION</b>The rationality of Definition of 'Hurt', Definition of 'Harm', 'Injury' being the combination of 'hurt' and 'harm', 'Injury' should be graded and Graded based on the 'Injured' time is good. There is still a certain degree of divergence about Graded based on the 'Injured' time.</p>

To establish the fingerprints of Xiasangju granules (with sugar and non-sugar forms) by HPLC, and provide reference for their identification and effective quality control. High performance liquid chromatography (HPLC) method was used to collect the fingerprints of 20 batches of non-sugar Xiasangju granules and 34 batches of sugar type Xiasangju granules. Their main different components were classified and screened by mode identification methods (principal component analysis, PCA, and orthogonal partial least squares discriminate analysis, OPLS-DA). The principal components were identified by comparing with reference standards. The fingerprints of Xiasangju granules (sugar type and non-sugar type) were established. PCA could not fully classify the two types of granules, while OPLS-DA could obviously classify these two different types of Xiasangju granules. Six components showed greatest difference between two types of granules, including salviaflaside, luteoloside and linarin. The developed mode identification method is helpful to control the overall quality of Xiasangju granules, and it provides an effective approach to quality evaluation.
