AIM: To develop a rat model of insulin resistance and observe the effect of puerarin injection on expression of GSK-3 in insulin resistance rats.METHEDS: 30 Wistar rats were divided into three groups randomly: control group,model group and puerarin group.The model group and puerarin group were given high fat diet(20% surcose,10% ard,(2.5)% chlesterol,1% cholic acid) for 4 weeks.Then the puerarin group was given abdominal injection puerarin 100(mg?kg~(-1)?d~(-1)) for six weeks.At the end of this experiment,we detect GSK-3 protein by western-blot analysis.Then computer image pattern analysis system was used to analyze the expression of GSK-3 in the hepatacyte.RESULTS: Tthe model group showed a hyperglycemia,hyperinsulinism,the ISI decreased and HOMA-IR increased.GSK-3 expression enhanced in the model group,but the expression of GSK-3 in puerarin group decreased compared to the model group.CONCLUSION: Puerarin injection can significantly decreased the expression of GSK-3 and improve insulin resistance.

Objective To dynamic monitoring the changes of serum cortisol,adrenocorticotropic hormone (ACTH) in children with sepsis and servere sepsis,and to assess it's relationship with clinical features.Methods Thirty children with sepsis were enrolled in this study from Sep 2010 to Jan 2011 in our hospital,and were divided into severe sepsis group (n =10) and sepsis group (n =20).The serum cortisol and ACTH were analysed in acute and recovery period respectively in both two groups,and compared with 10 non-sepsis children as control group.Results In the acute period,the level of serum cortisol in severe sepsis group [ (33.97 ±6.83) μg/ml ] was significantly higher than those in sepsis group [ (26.30 ± 10.43) μg/ml]and control group [ ( 19.06 ± 6.91 ) μg/ml ] ( P ＜ 0.01 ) ; the level of serum ACTH in severe sepsis group [ (25.47 ± 9.41 ) pg/ml ] was significantly higher than those in sepsis group [ ( 15.52 ± 5.85 ) pg/ml ] and control group [ (9.16 ± 3.02 ) pg/ml ] ( P ＜ 0.01 ).Conclusion Stress response exists in the early period of sepsis,and the levels of serum cortisol and ACTH are increased significantly.The levels of serum cortisol and ACTH are positive correlation with the severity of diseases,and they could be used as serious index and a marker for evaluating prognosis in children with sepsis.

0.05).Furthermore,logistic regressive equations of prediction probability and RE,SE,BIS were calculated as ln [Pk/(1-Pk)]=-19.825+0.243x,ln [Pk/(1-Pk)]=-18.012+0.236x and ln [Pk/(1-Pk)]=-21.780+0.316x,respectively.From the perspective of sensitivity/specificity,RE,SE and BIS had threshold values for regaining consciousness of 83,76 and 71 with sensitivity/specificity of 0.90/0.85,0.89/0.80 and 0.88/0.78,respectively.RE was 30s earlier than BIS in predicting regaining consciousness.Conclusion Compared with BIS,entropy index seems to be a more accurate and sensitive electroencephalographic measure,and is promising in clinical application.

20 normal males were examined by BIODEX isokinetic test and rehabilitation system,and data collected were used to observe the influence of angle and time on the isokinetic concentric constriction of knee joint. It was found that angle and time, especially angle factor obviously affected the testing results.

Aim To investigate the toxicity of isopsor-alen in HepG2 cells and its effects on bile acid, bile acid synthesis and transport. Methods Cell viability was evaluated by MTT assay and bile acid was deter-mined inside HepG2 cells, with exposure to various isopsoralen for 24h. The mRNA transcription of BSEP, MRP2, MRP3, NTCP, OATP2, OSTα, CYP7A1, CYP27 A1 , FXR and PXR were assessed by real-time PCR. Results The cell viability was decreased dose-dependently with isopsoralen in HepG2 cells, and IC50 was 118. 1μmol·L-1 exposure to isopsoralen for 24h. Bile acid inside cells significantly increased with 100 and 400 μmol · L-1 isopsoralen. Isopsoralen caused the down-regulation of MRP2 , MRP3 , CYP7 A1 mRNA at 25 μmol · L-1 . Beside these, the up-regulation of OATP2,OSTα,CYP27A1,FXR,PXR with 100 μmol· L-1 isopsoralen, but there was no significant change of BSEP and NTCP. Conclusion The results show that isopsoralen induces bile acid accumulation and cytotox-icity which may be associated with the down-regulation of MRP2, MRP3 in HepG2 cells.
