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.

Background C57BL/6andB10R Ⅲareroutinemurinespeciesusedinexperimental autoimmune uveitis (EAU).The inflammation is light for mouse after immunization whereas it is prominent for B10R Ⅲ.ObjectiveThis study was to observe the killing effect of interphotoreceptor retinoid binding protein (IRBP) 1-20-specific T cells on mouse retinal astrocyte.Th1 and Th17 cells effect in the EAU mechanism was discussed.MethodsB10RllⅢ mice and C57BL/6 mice were immunized with IRBP 161-180 and IRBP 1-20 in complete Freund adjuvant (CFA).The infiltrating cells of diseased B10R Ⅲ eyes were analyzed by flow cytometry.IRBP 1-20-specific T cells were isolated from the drainage lymph node and spleen and cultured in IL-2 or IL-23 for Th1 and Th17 cells polarization,respectively.Th1 and Th17 cells cultured for 5 days were seeded on the mouse retinal astrocyte monolayer pretreated with gamma interferon.Cell interaction was observed and the quantity of TNF-α was tested by ELISA.Every test was repeated 6 times and the mean was calculated.The maintenance of experimental animals complied with the Statement of ARVO.ResultsThere were lots of infiltrating cells in the eyes of B10Rm mice after immunization,including 9.5％ IFNγ+ cells,5.1％ IL-17+cells and 41.4％ CD45+ cells.Six days after IRBP1-20 stimulation and cultured by IL-2 and IL-23,44.0％ and 8.0％ cells were IFNγ+,and 1.0％ and 26.0％ cells were IL17+.Twentyfour hours after the interaction between Th1 or Th17 and retinal astrocyte,retinal astrocyte died and detached.The killing effect of Th17 was stronger than Th1.48 hours after co-culture of Th1 or Th17T cells with astrocytes,the concentrations of TNF-α were ( 500± 10 ) and ( 801 ±24 μg/L) μg/L,respectively,with a significant statistical difference (t =-20.36,P =0.00).ConclusionsBoth Th1 and Th17 can kill retinal astrocyte,but Th17 plays a key role in the EAU pathogenesis process.The killing effect is caused by intercellular contact and interaction under the induction of cytokines.

80 years.The 104 patients had hypertension and 63 no hypertension.Average Scr level was(104.3?14.1)?mol/L,in normal range.The correlation coefficients between Cockcroft-Gault equation and age was the best(r=0.665,P

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.

Objective To evaluate the accuracy of spectral entropy including response entropy(RE)and state entropy(SE)as a new electroencephalographic measure of depth of sedation during general anesthesia.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-55 yr undergoing elective abdominal surgery were studied.Anesthesia Was induced with intravenous propofol,fentanyl and vecuronium.After tracheal intubation anesthesia was maintained with sevoflurane inhalation and intermittent iv boluses of fentanyl and vecuronium.BP,HR,SpO2,spectral entropy(Datex-Ohmeda)and BIS(Aspect Medical)were monitored during anesthesia.Loss of eyelash reflex and unresponsiveness to verbal stimulus and mild prodding and shaking were considered to be signs of loss of consciousness(LOC).The time of regaining consciousness Was defined as the time when patients started responding to verbal commands.RE,SE and BIS were recorded before anesthesia(baseline),10 min before LOC,immediately after LOC,immediately after tracbeal intubation,1 h after skin incision,10 min before regaining consciousness immediately after consciousness was regained and 10 min after extubation.Results There were sisnificant changes in RE,SE and BIS during the transition from consciousness to LOC.The RE,SE and BIS values for LOC were 76,73 and 68 with sensitivity of 94%,95%and 92%and specificity of 92%,94%and 91%respectively.The accuracy of RE.SE and BIS in predicting LOC was 93%,95%and 94%respectively.The RE,SE and BIS values for regaining consciousness were 82,75 and 70 with sensitivity of 95%,95%and 91%and specificity of 93%,96%and 93%respectively.The accuracy in predicting regaining of consciousness was 98%,96%and 97%respectively.Conclusion Entropy index Can accurately monitor level of sedation during general anesthesia.
