5.Clinical study of the relationship between the serum high mobility group protein B1 and the acute organophosphorus pesticide poisoning
Chinese Journal of Postgraduates of Medicine 2011;34(7):31-33
Objective To study the correlation between the serum high mobility group protein B1 (HMGB1)and the acute organophosphorus pesticide poisoning(AOPP). Methods The serum HMGB1 levels of the 116 patients with AOPP(AOPP group)and 40 healthy adults(control group)were detected by immunoblotting method. According to illness severity, AOPP group was divided into mild group(40 cases),moderate group(39 cases)and severe group(37 cases), and severe group was divided into multiorgan dysfunction syndrome(MODS)group(20 cases)and no MODS group(17 cases). The serum levels of CHE,HMGB1 were compared. Results The absorbance of HMGB1 in severe group(2.91±0.12)was significantly higher than that in moderate group(2.15±0.17), mild group(1.16 ± 0.29)and control group (0.84±0.30)(P<0.01).The absorbance of HMGB1 in moderate group was significantly higher than that in mild group and control group(P<0.01). The absorbance of HMGB1 in mild group was significantly higher than that in control group(P<0.05). The absorbance of HMGB1 in MODS group was significantly higher than that in no MODS group(P<0.01),but the absorbance of CHE had no significant difference between two groups(P>0.05). Conclusions The degree of AOPP has notable correlation with the level of serum HMGB1. The level of serum HMGB1 is an useful index for evaluating the degree of AOPP.
6.Study of probe substrate specificity for human cytochrome P450 isoenzymes
Chinese Pharmacological Bulletin 2003;0(07):-
Analysis of metabolic activities of cytochrome P450 isoenzyme is a crucial index to study drug/toxicant metabolism, drug-drug interaction, polymorphism and et al. Due to this practice, it is important to use the proper probe substrate and to conduct the experiment under optimal conditions. The validation information in literatures on the most common and newest in vitro probe substrates have been reviewed.
7.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.
8.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.
9.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.
