28 mmol/g of bonded amount, and the theoretical plate number of EGSP column was about 24 707 N/m. The EGSP appeared to be a kind of excellent reversed-phase stationary phase with suitable hydrophobicity and various synergistic sites. The eugenol ligand bonded on silica gel could first provide π-π interaction sites for different analytes because of its benzene ring and alkenyl. In addition, the methoxy groups of eugenol were responsible for dipole-dipole and hydrogen-bonding interactions between the ligand and solutes in the effective separation process. Comparing with traditional C18 column and phenyl column, EGSP has an advantage in the fast separation of polar compounds under simple experimental conditions.A C6-silica hybrid monolithic column was prepared by click reaction with capillary silica monolith. Firstly, an azide-functionalized silica monolithic column was synthesized via sol-gel reaction with tetramethoxysilane (TMOS) and 3-azidopropyltrimethoxysilane (N3PTMS). Then 1-hexyne was covalently immobilized on the capillary monolith by the "azide-alkyne" click reaction to form C6-silica hybrid monolithic column. As an extraction media of polycyclic aromatic hydrocarbons (PAHs), the conditions for the preparation and modification of the monolith were carefully investigated according to the extraction efficiency. https://www.selleckchem.com/products/unc3866.html The enrichment factors for typical PAHs naphthalene, phenanthrene, pyrene and benzo a pyrene finally reached 95.9, 14.2, 103.2 and 57.8, respectively. The relative standard deviations (RSDs) for the extraction were lower than 5.5% (intra-day, t = 8) and 7.3% (inter-day, n = 10). Based on the in-tube solid phase microextraction (in-tube SPME), a new determination method for 16 PAHs was developed with high performance liquid chromatography (HPLC). The limits of detection (LODs, SN = 3) were 0.08-3.72 µg/L and the limits of quantification (LOQs, S/N = 10) were 0.26-12.40 µg/L for the PAHs. The spiked recoveries for the PAHs in soil samples were between 82.4% and 110.6% with the RSDs (n = 3) of 2.6%-7.9%. Comparison with the method of United States Environmental Protection Agency (U. S. EPA) for the PAIs determination in soil samples, the results showed good accuracy and high consistency. And the high extraction efficiency with high sensitivity and convenience was also demonstrated in the applications of the new approach.Mesoporous magnetic nanoparticles of Fe3O4 @ mSiO2 @ Cu2+ were synthesized by two methods of hydrothermal synthesis and room temperature synthesis. The synthesized mesoporous Fe3O4 @ mSiO2 @ Cu2+ nanoparticles presented uniform sizes, good magnetic properties and specific selectivity. In this work, a novel magnetic solid-phase extraction (MSPE) method based on mesoporous Fe3O4 @ mSiO2 @ Cu2+ nanoparticles (NPs) coupled with high performance liquid chromatography (HPLC) was developed for the simultaneous extraction of trace amount of microcystin-LR (MC-LR) in water samples. The MSPE extraction conditions and HPLC conditions were optimized. The results showed that good linear relationship (r = 0.999 4) was obtained between peak area and mass concentration of MC-LR in the range of 0.1-15 µg/L. The limit of detection was 0.025 µg/L, and the limit of quantification was 0.082 µg/L. Furthermore, this method was used for the analysis of algal toxins in water samples with the recovery of 78%. The results indicated that Fe3O4 @ mSiO2 @ Cu2+ magnetic nanoparticles were good pretreatment alternatives for the concentration of microcystin-LR in water samples.
To investigate the effect of peroxisiome proliferator activated receptor-α (PPAR-α) on the regulation of cardiomyocyte hypertrophy and the relationship between the effect of PPAR-α with PI3K/Akt//mTOR signal pathway.

Cardiomyocyte hypertrophy was induced by isoproterenol (ISO). The cell surface area was measured by image analysis system (Leica). The expressions of atrial natriuretic peptide (ANP), β-myosin heavy chain (β-MHC) and PPAR-α mRNA were detected by qRT-PCR. The protein expressions of Akt, mTOR and P70S6K were detected by Western blot. The expression of PPAR-α was suppressed by RNAi.

(1) The expression of PPAR-α was significantly reduced in cardiomyocyte hypertrophy. PPAR-α activator Fenofibrate (Feno) increased the expression of PPAR-α and suppressed cardiomyocyte hypertrophy. The inhibitory effect of Feno on cardiomyocyte hypertrophy was reversed by PPAR-α RNAi. (2) Feno significantly inhibited the increase of the protein expressions of p-Akt, p-mTOR and p-p70S6K in ISO induced cardiomyocyte hypertrophy, which could be blocked by PPAR-α RNAi. (3) PI3K antagonist LY294002 (LY) or mTOR antagonist rapamycin (RAPA) markedly-inhibited cardiomyocyte hypertrophy. The inhibitory effects of LY or RAPA on cardiomyocyte hypertrophy were reversed by PPAR-α RNAi.

PPAR-α can negatively regulate cardiomyocyte hypertrophy. The effect might be associated with PPAR-α inhiting PI3K/ Akt/mTOR signal pathway.

To comparatively study the effects of Rhubarbs from different regions on blood lipid and antioxi dation of hyperlipidemia rats.

Male rats were randomly divided into 9 groups ( n = 8) and fed with high-fat diet to replicate the hyperlipidemia model. Meanwhile, Rheum tanguticum was administrated intragastrically at two doses (3.0 g/kg and 1.0 g/kg), once a day for continuous 28 days. The effects of Rheum tanguticum planted in Gannan (RT-GN), Rheum tanguticum planted in Xinin (RT-XN) and Rheum plmatum planted in Lixian (RP-LX) were evaluated through detecting the parameters of blood lipids, blood viscosity and antioxidant system.

T-GN, RT-XN and RP-LX in the range of 1.0-3.0 g/kg could decrease the blood levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and malonaldehyde (MDA) in blood. Besides, they could reduce blood viscosity, increase high density lipoprotein (HDL) level and upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Interestingly, their effects on blood viscosity was obviously in a dose dependent manner. In addition, the effects of RT-GN on LDL, MDA and blood viscosity were not significantly different from those of RT-XN and better than those of RP-LX.

The RT has better hypolipidemic effects than the RP, but RT-GN and RT-XN are not different from the above effects.

To investigate the difference of liver enzyme levels and its correlation with serum ACE/ACE2 among yak and cattle on Qinghai-Tibetan plateau, and to further explore the biochemical mechanism of their liver of altitude adaptation.

The serum samples of yak were collected at 3,000 m, 3,500 m, 4,000 m and 4,300 m respectively, meanwhile the serum samples of migrated cattle on plateau (2,500 m) and lowland cattle (1,300 m) were also collected. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), cholinesterase (CHE), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), serum lipase (LPS), angiotensin converting enzyme(ACE), angiotensin converting enzyme-2 (ACE2) in serum were measured by using fully automatic blood biochemcal analyzer. We analysed the differences of the above enzymes and its correlation with ACE/ACE2. We used one way analysis of variance (ANOVA).

The levels of ALT in 4,000 m group and 4,300 m group of yak increased significantly compared with other groups,of liver enzymes' activities in mountainous yaks but not in cattle. However, all above these changes weren't actually correlated to the ratio of ACE/ACE2.
To investigate the effects of Shadu Cao Mixture (SDCM, traditional Chinese medicine) on immune functions of immunosuppression mice.

Fifty BALB/C mice were randomly divided into blank control group, model group, SDCM low-dose, middle-dose and high-dose group. Except the blank control group, other groups were intraperitoneal injected with cyclophosphamide (40 mg/kg) to establish immunosuppression mice model. The blank control group and model group received gavage administration with nonnal saline, while the other groups received gavage administration with different doses of SDCM (10, 20, 40 m/kg for 15 days) respectively. The number of leukocytes and serum levels of interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in peripheral blood, spleen index, and the function of NK cells were measured.

Compared with the model group , SDCM increased the number of leukocytes and serum concentrations of IL-2, TNF-α and IFN-γ in peripheral blood and improved the spleen index and the function of NK cells significantly (P < 0.05-0.01).

SDCM could remarkably enhance the immune functions of immunosuppression mice induced by cyclophosphamide.

To detect the levels of miR-499 and relative proteins in hearts of mice after exercise training, and investigate the mechanism of exercise-regulative apoptosis.

Male C57BL/6 mice were randomly divided into 3 groups( n = 14) sedentary (SE), exercise training 1 (ET1) and exercise training 2 (ET2) group. SE did not do any exercise. ET1 performed swimming training for 8 weeks. ET2 performed the same work as ET1 until the 5th week. Then, mice trained twice a day until the end of training. TUNEL assay was applied to test myocardial apoptosis, RT-PCR and Western blot were used to detect miR-499 and proteins levels respectively.

Compared with SE, stress in ET1 failed to affect apoptotic index (AI) and miR-499-CaN-Drp-1 pathway (P > 0.05). In contrast, exercise load in ET2 increased miR-499 level, decreased Drp-1 level and AI with statistical significance respectively (P < 0.05), but neither CaN expression nor CaN activity was changed significantly (P > 0.05).

Swimming training can inhibit myocardial apoptosis, and the decrease in Drp-l may be responsible for the reduced myocardial apoptosis. CaN, the upstream protein, does not participate in exercise-regulative apoptosis.

To investigate the effect of p65 gene inhibited by siRNA on neuronic differentiation in the marrow mesenchymal stem cells (MSCs).

The MSCs were transfected with Rn-p65-siRNA. Fasudil hydrochloride induced MSCs differentiating into neurons. The non-transfected group and negative control group (transfected with negative control siRNA marked by Cy3) were used as controls. The fluorescence expressed by transfected MSCs were observed under inverted fluorescence microscope at 24 h,48 h and 72 h after transfected with negative control siRNA. The viability of MSCs was detected by MTT at 24 h, 48 h and 72 h after transfected with Rn-p65-siRNA. The expressions of p65 mRNA and protein in MSCs were detected by RT-PCR and Western blot respectively. The expressions of p65 protein, NSE, MAP-2 and glial fibrillary acidic protein (GFAP) were detected by immunocytochemical method after transfection for 6 h.

The fluorescence of MSCs was mostly displayed after transfection of 72 hours and the efficiency of transfection was up to 83.
