The validation information in literatures on the most common and newest in vitro probe substrates have been reviewed.
4.Establishment of precision-cut fibrotic liver slice technique
Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(08):-
AIM: To establish the technique of precision-cut fibrotic liver slice (PCLS) and grope the optimal cultural conditions for researching the liver xenobiotic metabolism in vitro and the drug interaction. METHODS: Complex factors (higher fat diet, alcohol and CCl 4) were used to make the animal model of liver fibrosis. Fibrotic liver slices were prepared and cultivation system was established. Lactate dehydrogenase (LDH) leakage, glutathione S-transferase (GST) activity and 3[4,5-Dimethythiazole-2-yl]-2,5- diphenyltetrazolium bromide (MTT) reduction were chosen as indexes to assess the viability of the slice in different thickness, medium pH and cultural time. RESULTS: Rats were in earlier hepatic fibrosis after administration for 3 weeks. When the thickness of slices was 300 ?m and medium pH was 7.0, the LDH leakage, GST activity and MTT reduction could maintain on a steady level in 6 h. CONCLUSION: A 300 ?m of thickness, 7.0 of medium pH and 6 h of cultural time are the optimal slicing and culturing conditions for fibrotic liver slice.
5.Preparation and release and pharmacokinetics of sustained-release isoniazid
Chinese Pharmaceutical Journal 1998;(2):95-
To prepare and study the pharmacokinetics and release bioavailability in olunteers and concentrations in plasma in patients. METHODS: Ethylcellulose was used matrix in phase separation-coacervation for preparation of microencapsulation. The release experiments were performed in a rotating shaker. The isoniazid concentration in plasma was determined by spectrophotometrical method following a single oral dose of sustained-release cupsule and ordinary tablet respectively given to 10 volunteers in a open randomized cross-over test. MCP86 was used to process main pharmacokinetic parameters. RESULTS: The sustained-release of capsule and ordinary teblet in vitro, T50 was 1 h and 0.032 h respectively. The drug in sustained-release capsule was sustained release over 10 h. The main parameters in body: ordinary tablets: cmax=11.12 μgml-1, tmax=1.41 h, K=0.201 h-1; sustained release capsule: cmax=4.99 μgml-1, tmax=1.80 h, K=0.03 h-1. The concentration of blood at 36 h was (0±0)μgml-1 and 1.63 μgml-1 respectively. Except tmax, there was significant difference between the two fomulations (P<0.01). The concentration of blood in patient at 1.5 h and 36 h. ordinary tablet and sustained-release capsule respectively were (8.24±2.60)μgml-1, (0±0)μgml-1and (3.69±0.86)μgml-1, (2.09±0.56)μgml-1. CONCLUSION: The sustained-release capsule will play an important part in prevention and treatment of tuberculosis as the result of its reasonable formulation and simple technology.

Journal of Medical Postgraduates 2003;0(11):-
Objective:To investigate the consistency of two methods in the measurement of bone mineral density in the lateral lumbar vertebra.Methods:The bone mineral densities of the 2nd,3rd and 4th lumbar vertebras in 18 female patients,at a preset side lying position,were measured respectively by two methods(lateral spine analysis,LS and lateral vertebral analysis,LVA) provided by the dual-energy(X-ray) absorptiometry(GE Lunar,Prodigy).The results were recorded and analyzed by SPSS(Version(10.0).) The values of bone mineral density were displayed by boxplot,paired and analyzed by(Wilcoxon's) signed rank test and(Pearson's) correlation analysis.Statistical significance was considered when P(0.05),) and were clearly correlated(P
7.Chemoresistance of multi-drug resistance malignant glioma cells mediated by DNA-PKcs and its molecular mechanism
Journal of Jilin University(Medicine Edition) 2016;42(5):877-881
Objective:To obesrve the influence of DNA-PKcs in the chemoresistance of multi-drug resistance malignant glioma cells,and to explore its molecuIar mechanism in chemoresistance.Methods:siRNA was used to construct the DNA-PKcs knockdown human glioma U251 cell line;Western blotting method was used to detect the expressions of DNA-PKcs in U251 cells (U251 cells), doxorubicin (ADM)resistant U251 cells (U251/ADM cells),DNA-PKcs knockdown and ADM resistant U251 cells (U251/ADM/siDNA-PKcs cells).CCK8 method was used to detect the cell proliferation activity in three groups;Western blotting method was used to detect the expressions of MDR1, pNF-κB/p6, total Akt, pAkt/T308 and pAKT/S473 in the cells in three groups. Results:The expression level of DNA-PKcs in U251/ADM cells was significantly higher than those in U251 cells and U251/ADM/siDNA-PKcs cells (P < 0.01 ).The IC50 values of doxorubicin (ADM),paclitaxel (PTX), gemcitabine (GEM)in U251/ADM/siDNA-PKcs cells were significantly lower than that in U251/ADM cells (P <0.05);the expression levels of pAKT/S473,pNF-κB/p65,and MDR1 in U251/ADM/siDNA-PKcs cells were significantly lower than those in U251/ADM cells (P <0.01),but the total Akt and pAkt/T308 had no significant differences between two groups (P >0.05).Conclusion:DNA-PKcs can significantly enhance the chemoresistance of multi-drug resistance malignant glioma cells,the underlying mechanism is related to up-regulation of pAKT/S473,pNF-κB/p65 and MDR1 expressions.
