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.

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.

Objective To study the role of CXC chemokine receptor 5 (CXCR5) in the pathogenesis of bullous pemphigoid (BP) by detecting the expression of CXCR5 on follicular helper T (Tfh) cells in skin lesions of BP.Methods An immunohistochemical procedure was used to detect CXCR5 expression in biopsy specimens from skin lesions of 16 patients with BP and normal skin of 10 healthy individuals.Results CXCR5 was mainly expressed in the cytoplasm and membrane of Tfh cells in the basal cell layer of normal skin as well as in both basal cell layer and prickle cell layer of BP lesions.The number of CXCR5-positive ceils per high power field (× 400) was 11.16 ± 4.47 in normal skin specimens,significantly lower than that in lesional skin specimens (35.70 ± 12.20,t =6.07,P ＜ 0.01).Conclusion CXCR5 may be involved in the pathogenesis of BP.

ObjectiveTo investigate the clinical significance of determination of 20S proteasomal activities changes in circulating white blood cells (WBC) in patients with advanced gastric carcinoma.MethodsThe 20S proteasomal activities in circulating WBC separated from 80 patients with advanced gastric carcinoma were determined by 20S proteasome assay kit; the concentrations of interleukin-6(IL-6) in plasma were determined by radioimmunoassay method.The result was compared with that of 11 healthy volunteers.ResultsThe proteasomal activities in circulating WBC[(38.26 ±9.23),(101.85 ±27.63)pmol AMC/ ( s *mg pro) ] and concentrations of IL-6 [ (23.89 ± 6.76),(72.52 ± 20.71 ) ng/L ] of healthy volunteers and the patients with advanced gastric carcinoma had statistical significance (P ＜ 0.01 ).The proteasomal activities and the concentration of IL-6 were correlated with age,pathological type,weight changes,Karnofsky score and disease severe degree(P ＜ 0.01 );while they had no relationship with sex(P ＞ 0.05).Cox's proportional hazard regression model demonstrated that pathological type,Karnofsky score and proteasomal activities were the independent risk factors affecting the survival of patients with advanced gastric carcinoma (P ＜0.01 or ＜0.05).20S proteasomal activities and the concentration of IL-6 had positive correlation (r =0.691,P =0.000).ConclusionsThe proteasomal activites in circulating WBC and the concentration of IL-6 in plasma increase and are correlated with age,pathological type,weight changes,Karnofsky score and disease severe degree.Proteasomal activities in circulating WBC can be used as the prognostic reference factor of advanced gastric carcinoma.20S proteasomal activities and the concentration of IL-6 have positive correlation.

Objective To evaluate the clinical value of Gli1 expression in breast cancer.Methods Immunohistochemistry was used to analyze the protein expression of Glil in breast cancer tissues,adjacent cancer tissues and metastatic lymph node.Results ①Breast cancer tissues expressed high levels of Gli1 compared to paracancerous tissues.Gli1 overexpression was found in 93.3％ of breast cancer tissues with recurrence and metastasis and 81.2％ in breast cancer tissues without metastasis.Gli1 expression could be detected either in interstitial tissues of cancer or in cancer tissues,or in both.The rate of Gli1 overexpression was 89.3％ in the inter stitial tissues of the primary cancer with recurrence and metastasis and 13.4％ in interstitial tissues of breast cancer tissues without metastasis.The difference had statistical significance(P ＜ 0.001).②High expression of Gli1 in breast cancer tissues was closely related to early recurrence and metastasis of breast cancer.Gli1 expression displayed a significant correlation with relapse-free survival (RFS) (P =0.046).The recurrence rate was 17.8％ in the high expression group in breast cancer tissue,whereas it was only 6.2％ in the low expression group(P =0.046),while the recurrence rate was 31.2％ in the high expression group in interstitial tissues,whereas it was only 11.1％ in the low expression group(P ＜ 0.001).Conclusion The high expression of Gli1 in breast primary cancer tissues,metastasis tissues and interstitial tissues is associated with recurrence and metastasis of breast cancer.
