Objective To explore the effect of valproate(VPA) on body mass index(BMI),leptin and serum lipids in children with epilepsy.Methods (Twenty-)four cases with epilepsy were selected.BMI and serum levels of leptin,total cholesterol(TC),(triacylgly)-cerol(TG),high density lipoprotein-cholesterin(HDL-C),low density hipoprotein-cholesterin(LDL-C) after treated with VPA for 3 months and 6 months were determined.Results The levels of BMI,leptin,TC,TG,LDL-C after treated 3 months were all significantly higher than those of initial(all P0.05).Those in treated 6 months were same as levels of treated 3 months.Only LDL-C level was lower than that of 3 months and same as level of before treatment.Conclusion VPA do have efficacy to cause obesity in children with epilepsy,and most of the cases occur in the first 3 months after VPA treatment.

Objective To study whether sulphur fumigation can cause changes to the content of imperatorin in Angelicae Dahuricae Radix (Baizhi).Methods The fresh samples of Angelicae Dahuricae Radix were collected from some cultivation bases. Half of each batch root was fumigated with sulfur according to the conventional method, and another half was cut into slices and dried naturally (i.e. without sulfur fumigation). The content of imperatorin was determined by HPLC on C18 column (4.6 mm×250 mm, 5μm) with a gradient mobile phase of acetonitrile-water solution system at the follow rate of 1.0 mL/min, 35℃ of the column temperature, and the max plot in 210-800 nm of the detective wavelength.ResultsTotally 29 batches of fresh roots ofAngelica dahurica were collected. The average contents of imperatorin were 0.202% in the Angelicae Dahuricae Radix with sulfur fumigation and 0.120% in the Angelicae Dahuricae Radix without sulfur fumigation. Compared with the corresponding samples without sulfur fumigation, the content of imperatorin in every Angelicae Dahuricae Radix with sulfur fumigation decreased by 6.77%-77.56% with an average decrease of 39.86%.Conclusion The content of imperatorin decreased significantly in every batch of Angelicae Dahuricae Radix with sulphur fumigation. It shows that the sulphur fumigation method was not suitable for producing and processing Angelicae Dahuricae Radix from fresh roots ofA. dahurica.

The contents of coumarins in the sulfur fumigated Angelicae Dahuricae Radix (Baizhi, ADR) were reduced significantly. To achieve the quality control of ADR, the qualitative identification of sulfur fumigated ADR and quantitative model of imperatorin content should be established. The near-infrared (NIR) spectrograms of non-sulfur and sulfur fumigated ADR were collected by NIR diffuse reflectance spectroscopy technology and pretreated by the method of first derivative derivation and vector normalization. The Ward's Algorithm method was used for the cluster analysis. The non-sulfur and sulfur fumigated ADR can be quickly identified in the range of 8,806. 0-3 811.0 cm(-1) based on the cluster analysis. The NIR quantitative model of imperatorin was established by the contents of imperatorin determined by HPLC in combination with partial least squares regression analysis. According to the calibration model established in this study, correlation coefficients (R2), the root-mean-square error of cross-validation (RMSECV), and the root-mean-square error of prediction (RMSEP) for imperatorin were 0.982 8, 0.006 8, 0.011 8, respectively. The quantitative model of imperatorin can be applied to determine the content of imperatorin in ADR accurately.

OBJECTIVE:To establish an approach to determination of ketoconazole and desamethasone acetate in novel ketoconazole spraying film.METHODS:Chromatography was performed using a Waters Symmetry C 18 .The mobile phase consisted of methyl-monopotassium phosphate(4∶1).Detection wave was at239nm.The flowing rate was0.6ml/min.RESUL_ TS:Excellent linear correlations were showed when the concentrations of ketoconazole and desamethasone acetate were in the ranges of0.2～2mg/ml and0.02～0.2mg/ml respectively.The mean recoveries of ketoconazole and desamethasone acetate were98.41%(RSD=2.29%,n=6)and97.84%(RSD=2.60%,n=6)respectively.CONCLUSION:The established approach is precise,reliable and therefore applicable to the quality control of novel ketoconazole spraying film.

Objective To investigate the inhibitory effects and mechanisms of a nature product derivate oridonin on in?vasion of human lung cancer. Methods Human lung cancer A549 and PC-9 cell lines were treated with oridonin. MTS as?say was used to determine cell proliferation. Transwell assay was used to determine the cell invasion, and adhesion assay to determine the cell adhesion. Flow cytometry was used to determine cell cycle. Western blotting and realtime-PCR were used to detect expression levels of CDK1, mTOR, p53, p21, E-cadherin, CD44,β-catenin, uPA, MMP-2/9, p-AKT and p-Src. The luciferase reporter assay was used to detect the NF-κB promoter activity. Results In vitro proliferation, invasion and adhesion of A549 and PC-9 cells were significantly inhibited by oridonin. The cell cycle was halted by G2/M phase, and ex?pressions of E-cadherin, p53 and p21 were promoted, while expressions of CDK1, mTOR, CD44,β-catenin, uPA, MMP-2/9, p-AKT and p-Src and promoter activity of NF-κB were down-regulated. Conclusion Oridonin is able to inhibit the in vitro invasion of human lung cancer A549 and PC-9 cell lines, which might be correlated with its abilities to regulate the ty?rosine kinase activity.

Objective To investigate an optimum extracting technology for total glycosides from dried barks of Ilex rotunda Thunb. Methods The yields of pedunculoside and syringin by high performance liquid chromatography (HPLC) determination were taken as the indexes. Some parameters of the extraction technology were evaluated with an L9(3)4 orthogonal design. The optimum extraction parameters were used to extract total glycosides in laboratory. The feasibility was checked by determining the chemical constituents by means of HPLC method. Results The optimum extracting conditions were 12 times volumes of 50% ethanol as the solvent and refluxing 90 min each time for 3 times. An extract yield of total glycosides was 19.5% from barks of Ilex rotunda. Pedunculoside (292 mg/g), syringin (59.5 mg/g), sinapaldehyde glucoside, syringaresinol 4'-O-β-D-glucopyranoside, and syringaresinol 4',4'-di-O-β-D-glucopyranoside were detected in the extract. Conclusion Some glycosides were found in the extract with the optimum extraction technology in laboratory. The extraction technology is practicable and valid.

Objective Preparation of a stable and reliable atrioventricular blockage ( AVB) animal model is of great im-portance to anti-arrhythmic drugs and biological engineering research .The aim of the article was to establish a rat model of AVB in-duced by chemical ablation, providing an effective animal model for the development of new drugs . Methods 60 adult SD rats were randomly divided into 4 groups(n=15): normal saline (NS) group, Verapmil (Ver) group, chemical ablation group 1 and chemical ablation group 2.0.9%NaCl (5 mg/kg) was injected into caudal vein of each rat in NS group .Verapmil (5 mg/kg) was injected into the caudal vein in Ver group.Anhydrous ethanol(50μL)was injected into atrioventricular groove area in chemical abla-tion group 1.Anhydrous ethanol(50μL) was injected into atrioventricular node area in chemical ablation group 2.The electrocardio-grams of the rats were examined by electrophysiological recorder.HE staining and Connexin 43 (CX43) immunohistochemical tech-nique were applied to atrioventricular junctions of the rats . Results A rat model of AVB was successfully established .Compared with NS group([45 ±2.24]per field of view), there was a significant decrease in the CX43 expressions of chemical ablation group 1 and group 2 ([15.20 ±2.23]per field of view, [22.10 ±4.70]per field of view)(P<0.05).Concerning NS group and Ver group, myocyte tissues of the atrioventricular nodal region were detected to remain in order without obvious changes and the expres-sion of CX43 immunoreactive protein was obvious under light microscope.As to chemical ablation group 1 and group 2, myocyte tissues were in degenerative necrosis and the expression of CX43 im-munoreactive protein was in lighter staining.Compared with Ver group, the incidence rate(73.3%, 60.6%) and the mortality rate (33.3%, 26.7%)of third-degree AVB decreased remarkably(P<0.05). Conclusion Chemical ablation can be induced to estab-lish a stable and reliable rat model of AVB , providing an effective
animal model for the research and development of new anti-arrhythmic drugs.
