Clinical application value of Huanglian Jiedu Pills in improving syndrome of excess heat and fire toxin based on phase Ⅱ clinical trial study on plasma ATP, 4-HNE, and ACTH levels / 中国中药杂志

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

C: Consensus Cancer Driver Gene Caller / 基因组蛋白质组与生物信息学报·英文版

Next-generation sequencing has allowed identification of millions of somatic mutations in human cancer cells. A key challenge in interpreting cancer genomes is to distinguish drivers of cancer development among available genetic mutations. To address this issue, we present the first web-based application, consensus cancer driver gene caller (C), to identify the consensus driver genes using six different complementary strategies, i.e., frequency-based, machine learning-based, functional bias-based, clustering-based, statistics model-based, and network-based strategies. This application allows users to specify customized operations when calling driver genes, and provides solid statistical evaluations and interpretable visualizations on the integration results. C is implemented in Python and is freely available for public use at http://drivergene.rwebox.com/c3.

Study on the relationship between serum high density lipoprotein and Pi-deficiency syndrome in patients with coronary heart disease / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the relationship of Pi-deficiency syndrome in TCM with the change of serum high density lipoprotein (HDL) in blood lipid metabolic disorder.</p><p><b>METHODS</b>Sixty-eight patients with confirmed coronary heart disease (CHD) were selected for TCM syndrome typing into Pi-deficiency (PD) group and non-Pi-deficiency (NPD) group. Routine blood lipids and serum lipoprotein electrophoretogram (SLPG) were determined in all patients to analyze the total content of HDL and its relative contents of sub-components HDL(1-5), as well as their relation with PD syndrome. Besides, a healthy control group (62 cases) was set up.</p><p><b>RESULTS</b>The level of serum HDL-C was lowered, SLPG abnormality rate increased in the patients with CHD, with total HDL and the relative contents of subcomponent HDL(1) and HDL(3) significantly lower than those in the healthy control group (P<0.01). The total HDL, HDL(1) and HDL(3) in the PD group were also lower than those in the NPD group (P<0.05, P<0.01).</p><p><b>CONCLUSION</b>Serum HDL and its sub-components showed a definite relation with TCM PD syndrome type, therefore, further exploring the granular specificity of HDL and its sub-components as well as their influence on reverse cholesterol transport (RCT) may hopefully provide clues for developing RCT regulatory Chinese new drugs and for CHD prevention and treatment.</p>

Atorvastatin Inhibits The Development of Macrophages to Foam Cells / 中华高血压杂志

Objective To investigate effects of atorvastatin on the development from macrophages (HMDM) to foam cells.Methods Monocytes were isolated from human peripheral blood by Ficoll-Hypaque density gradient centrifugation and plastic adsorptive process.The isolated cells were stimulated by phorbol 12-myristate 13-acetate (PMA) (50 nmol/L) for 48 h and transformed to macrophages.Macrophages were co-incubated with 80 mg/L ox- idized low density lipoprotein (ox-LDL) and atorvastatin (0-100 ?mol/L),respectively for 0,6,12 and 24 h. Total cholesterol (TC),free cholesterol (FC) and protein (Pro) in cultured cells were quantitatively analyzed by high performance chromatography (HPLC) analysis and modified Lowry protein assay.Results When macropha- ges were incubated with 80 mg/L ox-LDL,the ratio of TC/Pro was greater than 20,and large amount of lipid drop- lets were displayed indicating the formation of foam cells.Atorvastatin decreased TC/Pro ratio in foam cells in a concentration and time dependent manner (0-100 ?mol/L)(P
