    Abstract Kai-Xin-San (KXS) is a Chinese medicine formulation that is commonly used to treat depression caused by dual deficiencies in the heart and spleen. Recent studies indicated that miRNAs were involved in the pathophysiology of depression. However, there have been few studies on the mechanism underlying the miRNAs directly mediating antidepressant at clinical level, especially in nature drugs and TCM compound. In this study, we identified circulating miRNAs defferentially expressed among the depression patients (DPs), DPs who underwent 8weeks of KXS treatment and health controls (HCs). A total of 45 miRNAs (17 were up-regulated and 28 were down-regulated) were significantly differentially expressed among three groups. Subsequently, qRT-PCR was used to verify 10 differentially expressed candidate miRNAs in more serum samples, and the results showed that 6 miRNAs (miR-1281, miR-365a-3p, miR-2861, miR-16-5p, miR-1202 and miR-451a) were consistent with the results of microarray. Among them, miR-1281, was the novel dynamically altered and appeared to be specifically related to depression and antidepressant effects of KXS. MicroRNA-gene-pathway-net analysis showed that miR-1281-regulated genes are mostly key nodes in the classical signaling pathway related to depression. Additionally, our data suggest that ADCY1 and DVL1 were the targets of miR-1281. Thus, based on the discovery of miRNA expression profiles in vivo, our findings suggest a new role for miR-1281 related to depression and demonstrated in vitro that KXS may activate cAMP/PKA/ERK/CREB and Wnt/β-catenin signal transduction pathways by down-regulating miR-1281 that targets ADCY1 and DVL1 to achieve its role in neuronal cell protection.

    Abstract This study aims to conduct a meta-analysis to evaluate the effects of niacin on serum lipids and glucose in patients with type 2 diabetes mellitus (T2DM).A comprehensive literature search in Medline, Scopus, AMED, Cochrane and Clinical trial registry databases was performed to identify randomized controlled trials investigating the effect of niacin on serum HDL cholesterol (HDL-c), LDL cholesterol (LDL-c), triglycerides (TG) and fasting plasma glucose (FPG). Pooled effects were measured by weighted mean difference (WMD) using fixed-effects or random-effects models. Quality assessment, and subgroup, meta-regression and sensitivity analyses were conducted using standard methods. Inter-study heterogeneity was assessed and quantified.The estimated pooled mean changes (95% confidence interval) with niacin were 0.27 (95% CI: 0.24 to 0.30; P < 0.001) mmol/L for HDL-c, −0.250 (95% CI: −0.47 to −0.03; P < 0.05) mmol/L for LDL-c and −0.39 (95% CI: −0.43 to −0.34; P < 0.001) mmol/L for TG compared with controls. There was a significant heterogeneity for the impact of niacin on LDL-c and FPG. Subgroup analyses revealed a significant increase in FPG 0.085 (95% CI: 0.029 to 0.141; P < 0.05) mmol/L compared with controls in patients with long term treatment. Our analysis also showed the absence of publication bias and any dose-response relations between niacin and effect size.Analysis of the results showed that niacin alone or in combination significantly improved lipid abnormalities in patients with TDM, but requires monitoring of glucose in long term treatment.

    Abstract A selective liquid chromatographic–mass spectrometric method (LC–MS/MS) has been established and validated for simultaneous determination of subutinib and its active metabolite in human plasma. Plasma samples were extracted by liquid–liquid extraction with ethyl acetate and separated on a Wondasil C18 (150mm×2.1mm, 3.5μm), with methanol–0.2% formic acid solution (73:27, v/v) as mobile phase at flow rate of 0.2ml/min. The linear range was 0.25–100ng/mL for subutinib and 0.125–50.0ng/mL for its active metabolite, with lower limit of quantitation of 0.25ng/mL and 0.125ng/mL, respectively. Intra- and inter-run precision were within 7.0 and 13.1%, and the accuracies (relative errors) were<7.0 and 8.0%, with the extraction recoveries 97.0–101.2% and 93.0–98.1% for the two analytes, respectively. The validated method was successfully applied to a pharmacokinetic study of subutinib and its active metabolite in human after oral administration of subutinib maleate capsules.

    Abstract A highly sensitive and rapid liquid chromatography-tandem mass spectrometry method was developed for the determination of clinofibrate in human urine. The analyte and IS were extracted through a simple protein precipitation by the mixture of acetonitrile and 1 mol/L hydrochloric acid (95:5, v/v) and separated on an Inspire C18 (150 mm x 4.6 mm I.D., 5 μm particle size) column using isocratic elution with methanol and water containing 0.1% formic acid and 10 mM ammonium acetate (90:10, v/v). Mass spectrometric detection was performed in electrospray positive ionization MRM mode. The mass transition was m/z 486.3-->175.0 for clinofibrate and m/z 361.1-->233.1 for IS, respectively. The flow rate was 0.6 mL/min and the column oven temperature was set at 35 °C. The total run time was 6.5 min. Good linear relationships were obtained for all analytes over the concentrations ranging of 0.1002-10.02 μg/mL (r2 = 0.9991) and the limit of quantification was 0.1002 μg/mL. The extraction recovery was larger than 87.4% and intra- and inter-batch precision and accuracy with RSD were all less than 6.5%. The total amount of unchanged clinofibrate excreted in urine was less than 0.34%. This method was successfully applied to the pharmacokinetic study of clinofibrate in human urine.

    Abstract A convenient and rapid HPLC method was developed for the determination of clinofibrate in human plasma using simple protein precipitation with the mixture of acetonitrile and 1M hydrochloric acid (95:5, v/v) followed by separation using an Inspire C₁₈ column with isocratic elution. The detection wavelength was 232nm and the flow rate was 1.0ml/min. The mobile phase consisted of acetonitrile and water containing 0.4% ortho-phosphoric acid (73:27, v/v). Linear calibration curve was obtained over the concentrations ranging from 0.5μg/ml to 32μg/ml (r²=0.999) with LLOQ of 0.5μg/ml. The RSD in both the intra-run and inter-run precision study was less than 5.4% and the extraction recoveries were above 90.7%. The HPLC method is reproducible and suitable for the quantification of clinofibrate in plasma. This method was successfully applied to the pharmacokinetic studies of clinofibrate in healthy volunteers. The elimination half-lives (t₁/₂) were (20.47±3.44), (18.19±2.62) and (21.51±4.78)h after single oral administration of 200, 400 and 600mg clinofibrate, respectively. The results of WinNonlin software showed that the area under the plasma concentration versus time curve from time 0 to 72h (AUC₀–₇₂) and peak plasma concentration (Cₘₐₓ) were linearly related to dose (P>0.05).

    Abstract As a well-known traditional Chinese medicine the root bark of Aralia taibaiensis has traditionally been used as the medicine considered alleviating several disorders including diabetes mellitus (DM). Chikusetsu saponin IVa (CHS) has been defined as a major active ingredient of triterpenoid saponins extracted from Aralia taibaiensis. The scientific evidence of anti-diabetic effect for CHS remains unknown and the purpose of our study was to study its hypoglycemic and insulin secretagogue activities.In vivo studies were performed on type 2 diabetic mellitus (T2DM) rats given CHS for 28 days to test the antihyperglycemic activity. The in vitro effects and possible mechanisms of CHS on the insulin secretion in pancreatic β-cell line βTC3 were determined.Oral administration of CHS dose-dependently increased the level of serum insulin and decreased the rise in blood glucose level in an in vivo treatment. In vitro, CHS potently stimulated the release of insulin from βTC3 cells at both basal and stimulatory glucose concentrations, the effect which was changed by the removal of extracellular Ca2+. Two methods showed that CHS enhanced the intracellular calcium levels in βTC3 cells. CHS was capable of enhancing the phosphorylation of extracellular signal-regulated protein kinases C (PKC), which could be reversed by a PKC inhibitor (RO320432), and the insulin secretion induced by CHS was also inhibited by RO320432. Further study also showed that the insulinotropic effect, intracellular calcium levels and the phosphorylation of PKC were reduced by inhibiting G protein-coupled receptor 40 (GPR40) by a GPR40 inhibitor (DC126026).These observations suggest that the signaling of CHS-induced insulin secretion from βTC3 cells via GPR40 mediated calcium and PKC pathways and thus CHS might be developed into a new potential for therapeutic agent used in T2DM patients.

    Abstract Traditional Chinese medicine uses a systemic treatment approach, targeting multiple etiological factors simultaneously. Danhong injection (DHI), a very popular Chinese medicine injection, is reported to be effective for many cardiovascular conditions. The primary active ingredients of DHI, and their systemic and interrelated mechanism have not been evaluated in an established myocardial ischemia/reperfusion (MI/R) model. We identified the main active constituents in DHI, including hydroxysafflor yellow A (A), salvianolic acid B (B), and danshensu (C), by HPLC fingerprint analysis and assessed their effect on MI/R rats and cardiomyocytes. These 3 compounds and DHI all decreased the levels of IL-1, TNF-α, and MDA, increased those of IL-10 and SOD activity in vivo and in vitro, and had antiapoptotic effects, as shown by flow cytometric analysis and TUNEL assay. Moreover, these compounds increased phosphorylation of Akt and ERK1/2 in cardiomyocytes. Interestingly, we found compound A exerted a more prominent anti-inflammatory effect than B and C, by decreasing NF-κB levels; compound B had more powerful antioxidative capacity than A and C, by increasing Nrf2 expression; compound C had stronger antiapoptotic ability than A and B, by lowering caspase-3 activity. Our results elucidate the mechanisms by which DHI protects against MI/R induced injury.
