Shenling Baizhu Powder alleviates chronic inflammation to prevent type 2 diabetes of ZDF rats via intestinal flora / 中国中药杂志

This study explored the mechanism of Shenling Baizhu Powder(SLBZP) in the prevention and treatment of type 2 diabetes from the perspective of flora disorder and chronic inflammation. Fifty rats were randomly divided into normal control group, model control group, low-dose SLBZP group, medium-dose SLBZP group, and high-dose SLBZP group, with 10 rats in each group. The rats of 5 weeks old were administrated by gavage with ultrapure water and different doses of SLBZP decoction. The basic indicators such as body weight and blood glucose were monitored every week, and stool and intestinal contents were collected from the rats of 9 weeks old for 16 S rRNA sequencing and metabolomic analysis. An automatic biochemical analyzer was used to measure the serum biochemical indicators, ELISA to measure serum insulin, and chipsets to measure leptin and inflammatory cytokines. The results showed that SLBZP reduced the body weight as well as blood glucose, glycosylated hemoglobin, and lipid levels. In the rats of 9 weeks, the relative abundance of Anaerostipes, Turicibacter, Bilophila, Ochrobactrum, Acinetobacter, and Prevotella decreased significantly in the model control group, which can be increased in the high-dose SLBZP group; the relative abundance of Psychrobacter, Lactobacillus, Roseburia and Staphylococcus significantly increased in the model control group, which can be down-regulated in the high-dose SLBZP group. The differential metabolites of intestinal flora included 4-hydroxyphenylpyruvic acid, phenylpyruvic acid, octanoic acid, 3-indolepropionic acid, oxoglutaric acid, malonic acid, 3-methyl-2-oxovaleric acid, and methylmalonic acid. Moreover, SLBZP significantly lowered the levels of free insulin, insulin resistance and leptin resistance in rats. The variations in the serum levels of interleukin 1β(IL-1β) and monocyte chemoattractant protein-1(MCP-1) showed that SLBZP could alleviate chronic inflammation in rats. In conclusion, SLBZP can regulate intestinal flora and metabolites and relieve chronic inflammation to control obesity and prevent type 2 diabetes.

Comparing the effects of depression, anxiety, and comorbidity on quality-of-life, adverse outcomes, and medical expenditure in Chinese patients with acute coronary syndrome / 中华医学杂志(英文版)

Background:@#Depression and anxiety have been correlated with elevated risks for quality-of-life (QOL), adverse outcomes, and medical expenditure in patients with acute coronary syndrome (ACS). However, the relevant data are lacking for Chinese ACS populations, especially regarding different effects of major depression, anxiety, and comorbidity. The objective of this study was to evaluate the dynamic changes of depression and/or anxiety over 12 months and examine the effects of depression, anxiety, and comorbidity on QOL, adverse outcomes, and medical expenditure in Chinese patients with ACS.@*Methods:@#For this prospective longitudinal study, a total of 647 patients with ACS were recruited from North China between January 2013 and June 2015. Among them, 531 patients (82.1%) completed 12-month follow-ups. Logistic regression model was utilized for analyzing the association of baseline major depression, anxiety, and comorbidity with 12-month all-cause mortality, cardiovascular events, QOL, and health expenditure.@*Results:@#During a follow-up period of 12 months, 7.3% experienced non-fatal myocardial infarction (MI) and 35.8% cardiac rehospitalization. Baseline comorbidity, rather than major depression/anxiety, strongly predicted poor 12-month QOL as measured by short-form health survey-12 (odds ratio [OR]: 1.77, 95% confidence interval [CI]: 1.22–2.52, P = 0.003). Regarding 12-month non-fatal MI and cardiac re-hospitalization, baseline anxiety (OR: 2.83, 95% CI: 1.33–5.89, P < 0.01; OR: 4.47, 95% CI: 1.50–13.00, P < 0.01), major depression (OR: 2.58, 95% CI: 1.02–6.15, P < 0.05; OR: 5.22, 95% CI: 1.42–17.57, P < 0.03), and comorbidity (OR: 6.33, 95% CI: 2.96–13.79, P < 0.0001, OR: 14.08, 95% CI: 4.99–41.66, P < 0.0001) were all independent predictors, and comorbidity had the highest predictive value. Number of re-hospitalization stay, admission frequency within 12 months and medical expenditure within 2 months were the highest in patients with ACS with comorbidity.@*Conclusions:@#Major depression and anxiety may predict 12-month non-fatal MI and cardiac re-hospitalization. However, comorbidity has the highest predictive value with greater medical expenditure and worse QOL in Chinese patients with ACS. And depression with comorbid anxiety may be a new target of mood status in patients with ACS.

PPARγ non-agonist ligand:the structure optimization based on PPARγ partial agonist / 药学学报

Recent studies indicate that insulin-sensitizing activity of TZDs occurs through the inhibition of PPARγ Ser273 phosphorylation mediated by cyclin-dependent kinase 5(Cdk5), which is resulted from the binding activity for PPARγ. While, the side effects of TZDs may be related to the agonistic potency for PPARγ. In this article, 15 target compounds were designed and synthesized based on the structure of PPAR γ partial agonist INT131, with the aim of maintaining the insulin-sensitizing activity and reducing the side effects of INT131. The structures of these compounds were confirmed by 1H NMR and ESI-MS, and their binding activities and agonistic potencies for PPARγ were measured. The binding activity of compound 15 is 88.47% of rosiglitazone, which is similar to INT131 (98.55%), but the agonistic potency of compound 15 is 1.41% of rosiglitazone, obviously lower than INT131 (15.18%).

The anti-tumor activity and molecular mechanisms of an Aurora kinase inhibitor ZLJ213 in suppressing colon cancer growth / 药学学报

The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.

The biological function of miR-214 in colon cancer HCT116 cells / 肿瘤

Objective: To investigate the expression of miR-214 (microRNA-214) in different colon cancer cell lines and its effect on the proliferation and apoptosis of HCT116 cells. Methods: The expressions of miR-214 and PIM1 mRNA in different colon cancer cell lines were detected by real-time fluorogenic quantitative-PCR, and the relationship between miR-214 and PIM1 mRNA expression was evaluated. The miR-214 mimics was transfected into HCT116 cells by LipofectAMINE 2000, then the expressions of miR-214 and PIM1 mRNA levels were detected by real-time fluorogenic quantitative-PCR. The change of proliferation ablility of HCT116 cells was detected by MTT method and colony-formation assay. The flow cytometry was used to examine the changes of apoptosis and cell cycle distribution. Results: The expression of miR-214 was down-regulated in HCT116 cells. The expression of miR-214 was negatively correlated with the expression of PIM1 mRNA in colon cancer cells (r = -0.943, P = 0.016). After transfection with miR-214 mimics, the expression level of miR-214 was up-regulated as compared with no transfection. The high expression level of miR-214 increased in miR-214 mimics group compared with that in the negative control group (P < 0.01). The high expression level of miR-214 could significantly inhibit the expression of PIM1 mRNA. After transfection with miR-214 mimics, the number of colonies was decreased (P = 0.026 9), the cell growth was inhibited (P < 0.000 1), the apoptosis rate was increased (P = 0.010 4), and the proportion of G1-stage cells was decreased as well as the proportion of S-stage cells was increased. Conclusion: MiR-214 can inhibit the proliferation and promote the apoptosis of colon cancer HCT116 cells. MiR-214 may act as a tumor suppressor in colorectal cancer by inhibiting PIM1.

Reference values of brachial-ankle pulse wave velocity for Northern Chinese / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Brachial-ankle pulse wave velocity (baPWV) is a reliable method for measuring arterial elasticity, but the absence of reference value for baPWV has limited its wide use. We conducted an epidemical study in north China to investigate the reference value of baPWV for Chinese people and its influential factors.</p><p><b>METHODS</b>A total of 974 identified healthy subjects were recruited in this study. The values of baPWV were evaluated noninvasively with an automatic device.</p><p><b>RESULTS</b>For healthy population, the mean value of baPWV was higher for male (P < 0.001). Multiple regression analysis demonstrated that both age and systolic blood pressure were positively associated with baPWV for male and female (P < 0.001). BaPWV value was higher in male than in female in younger group (< 50 years) but not in older group (P <or= 0.001). The upper limits of baPWV were 1394/1264 cm/s, 1435/1361 cm/s, 1552/1433 cm/s, 1597/1609 cm/s and 1798/1915 cm/s for healthy male/female at 10 years interval (age range 20 - 70 years).</p><p><b>CONCLUSIONS</b>Aging is the most important reason of arterial stiffness, but the effect of age on baPWV augmentation is greater for healthy female than their male counterpart. The reference values of baPWV by sex and age are very useful for clinical and preventive medicine.</p>

Effects of dietary supplementation with clostridium butyricum on the growth performance and humoral immune response in Miichthys miiuy / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

The effects of dietary supplementation with Clostridium butyricum on growth performance and humoral immune response in Miichthys miiuy were evaluated. One hundred and fifty Miichthys miiuy weighing approximately 200-260 g were divided into five groups and reared in 15 tanks with closed circuiting culture system. The animals were fed 5 diets: basal diet only (control) or supplemented of the basal diet with C. butyricum at doses of 10(3) (CB1), 10(5) (CB2), 10(7) (CB3) or 10(9) (CB4) CFU/g. Compared with the control, the serum phenoloxidase activity was significantly increased by the supplementation (P<0.05), acid phosphatases activity was increased significantly (P<0.05) at the doses of 10(9) CFU/g. Serum lysozyme activity peaked at dose of 10(7) CFU/g and in the skin mucus at dose of 10(9) CFU/g. Immunoglobulin M level in the serum and skin mucus was increased except at dose of 10(3) CFU/g (P<0.05). The growth at the dose of 10(9) CFU/g was higher than that of the control (P<0.05). It is concluded that supplementation of C. butyricum can mediate the humoral immune responses and improve the growth performance in Miichthys miiuy.
