OBJECTIVE:To determine serum concentrations of phenbarbital(PB),phenytoin sodium(PHT),carbamazepine(CBZ)by micellar electrokinetic capillary chromatograph(MEKC).METHODS:The determination was performed on elastic quartz column(37 cm?50 ?m)with barbital as internal standard.The buffer solution consisted of 10 mmol?L-1 phosphate sodium buffer-30 mmol?L-1 SDS sodium(micellar phase)-15% methanol at a constant voltage of 18 kV.The detection wavelength was set at 210 nm.RESULTS:The linear concentration ranges of PB and PHT were 2.5～80 ?g?mL-1,with detective concentration of 0.1 ?g?mL-1;the linear range and detective concentration of CBZ were 1～32 ?g?mL-1 and 0.2 ?g?mL-1,respectively.The average recoveries of the PB,PHT,and CBZ were 99.90%,99.91%,and 99.42%,respectively.CONCLUSION:The method is rapid,simple,accurate,sensitive and reproducible,and suitable for clinical monitoring of drug level and pharmaceutical study.

AIM: To investigate the adsorption mechanism of pueraria on the molecular imprinting polywer(MIP) and Scatchard analysis was carried out. METHODS: Pueraria MIP was synthesized using pueraria as the template,acrylamide as the functional monomer and ethylene glycol dimethaerylate(EDMA) as the crosslinker. RESULTS: The result showed that at least two classes of binding sites were formed in the imprinted polymer.Extracting compounds from Radix Pueraria was separated by MIP. CONCLUSION: The component of the products is analyzed by HPLC.The result shows that the final products contain pueraria and the other two kinds of isoflavone.

OBJECTIVE: To establish a method for the determination of the content of thiomersal in hepatitis B vaccine. METHODS: The content of thiomersal in hepatitis B vaccine was determined by flow injection-hydride generation atomic absorption spectrometry. The samples were treated by reflux digestion method with 4% sulphuric acid as medium,0.5% potassium borohydride as reducing agent,and 0.5% sulphuric acid as supporting liquid. RESULTS: The linear range of thiomersal was 5.0～100 ?g?L-1,with an average recovery rate of 100.6%(RSD=0.89%) and the lowest detection limit of 1.00 ?g?L-1. CONCLUSION: The method is simple,rapid and sensitive,and suitable for the determination of the content of thiomersal in hepatitis B vaccine.

ve To increase the analytical efficacy and the sensitivity of determination of trace chloroform and tetrachloro-methane in water. Methods Headspace solid phase microextraction (HSSPME) analysis was applied to replace the traditional headspace method in determination of trace chloroform and tetrachloro-methane in water. Results The lowest detection limits were 0.05?g/L for chloroform and 0.005?g/L for tetrachloro-methane respec-tively. The precisions and accuracies all accorded with the requirements of determination. Conclusion The method of HSSPME was easy and rapid to operate, revealed reliable and accurate results and good practicability. It also showed higher sensitivity without any organic solvent, compared with that of traditional headspace method.

OBJECTIVE:To prepare folic acid(FA)-loaded vincristine(VCR)nano liposome(VCR-nLip-FA)and to study its effects on human liver and lung cancer cells. METHODS:VCR-nLip-FA was prepared by ammonium sulfate gradient method,and particle size,Zeta-potential,encapsulation rate and release rate were investigated. Taking human liver cancer HepG2 cells and lung cancer A549 cells as example,uptake rate and inhibitory effect in vitro (5-80 μg/ml) were compared between VCR-nLip-FA and VCR-nLip. RESULTS:The particle size distribution,average particle size,average Zeta-potential,average encapsulation rate and 24 h accumulative release rate of VCR-nLip-FA were 98.1-159.0 nm,132.2 nm,-40.1 mV,(86.6±3.5)%(n=4)and(42.2± 2.6)%. Compared with VCR-nLip,there was no statistical significance in uptake rate of A549 cells to VCR-nLip-FA and inhibitory effect of VCR-nLip-FA on A549 cell viability (P>0.05);uptake rate of HepG2 cells to VCR-nLip-FA and inhibitory effect of VCR-nLip-FA on HepG2 cell viability increased significantly (P<0.01),in dose-dependent manner. CONCLUSIONS:Prepared VCR-nLip-FA can target anti-tumor drug to HepG2 cells efficiently,and highly inhibit the growth of HepG2 cells. But it has no higher effects on A549 cells.

BACKGROUND:Central nerve damage and peripheral nerve injury are common clinical problems that have no ideal treatment. Nerve growth factor has an important role in neuronal repairing and growth. But its local injections may have shorts of inactivation and loss. OBJECTIVE:To construct human nerve growth factor beta recombinant plasmids, which are transfected into bone marrow mesenchymal stem cells from the rabbit mandible by lentiviral vectors, and to investigate the bioactivity of human nerve growth factor beta. METHODS:pDC316-hNGFβ-mCMV-EGFP plasmids were constructed via lentiviral vectors using Hind III+Not I digestion. Bone marrow mesenchymal stem cells from the rabbit mandible were isolated and cultured, and then transfected by recombinant plasmids. The expression of human nerve growth factor beta in transfected cells was detected by ELISA method. RESULTS AND CONCLUSION:pDC316-hNGFβ-mCMV-EGFP plasmids were proved to be constructed successful y by gene sequencing and enzyme identification. The transfected cells under a fluorescence microscope emitted green fluorescence, and the fluorescence intensity had no change with incubation time. The expression of human nerve growth factor beta was maintained at a level of 25μg/L at 7 days after celltransfection, and the bioacitivty was increased significnalty.
