Objective To investigate the changes of serum adipocyte fatty acid binding protein (A-FABP) and high sensitivity C reactive protein(hs-CRP) in patients with acute ischemic stroke .Methods The total of 116 patients with acute ischemic stroke and 80 synchronously examined healthy people(controls) were collected .The levels of hs-CRP and A-FABP were detected by double-antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA) in all the subjects .Stroke severity were scored by modified Rankin Scale (mRS) .The patients with acute ischemic stroke were divided into the light (mRS≤3) and the severe group(mRS>3) .Changes of the level of hs-CRP and A-FABP were compared in two groups .Linear correlation and regression analysis were per-formed to hs-CRP and A-FABP .Results The levels of serum hs-CRP and A-FABP were significantly higher in acute ischemic stroke group than those in the control group .The severer the neurologic impairment degree was in the patients with acute ischemic stroke ,the higher the levels of serum hs-CRP and A-FABP .Linear correlation and regression analysis results showed that the level of A-FABP was significantly positively correlated with the level of hs-CRP .Conclusion The levels of serum hs-CRP and A-FABP is associated with acute ischemic stroke .The level of A-FABP is significantly positively correlated with the level of hs-CRP .The hs-CRP and A-FABP may have an action in occurrence and development of acute ischemic stroke .

Objective To study As2O3toxicity on rat liver in a retrograde isolated hepatic perfusion model. Methods In this study 104 male Sprague-Dawley rats weighing between 300 and 400 g were used. Eight male SD rats were used for preoperatively normal control and the remaining rats were randomly divided into 4 subgroups receiving As2O3at dosage of 0 mg/kg,0.75 mg/kg, 1.5 mg/kg, 3 mg/kg respectively. Modified RIHP was used in which As2O3was infused through hepatic artery. Ringer's lactate was retrogradly infused through hepatic veins and the portal vein was used as the outflow tract. Hepatic function, pathology and liver enzymes were assessed at different time points. As2O3concentration was monitered during the perfusion in rats of subgroup C. Results Serum ALT and AST rose to the peak on the first day, returning to normal after 3 or 7 days in all four subgroups. There was no difference between the peak levels of serum ALT and AST between subgroup A and B. Differences in serum ALT、AST level between subgroup A and C, A and D, B and C, B and D, C and D were all statistically significant (FALT=40.811,P<0.01;FAST= 48.212,P <0.01). On day 7, ALT and AST in subgroup D were still statistically higher when compared with that of other subgroups and normal control (FALT=13.928, P<0.01;FAST=17.942, P<0.01), and the hepatic pathology showed necrosis of the hepatocyte. The peak levels of As2O3were 13.21±0.82(μg/ ml) and 0.09±0.008 (μg/ml)in rats liver and systemic circulation in subgroup C during isolated perfuision. There were significant differences between the peak levels of concentration of As2O3in rats liver and systemic circulation (t=35.758,P<0.01). Conclusions The hepatic toxicity is reversible caused by As2O3when given at a dosage of 1.5 mg/kg of As2O3in a murine model of RIHP.

Objective To establish a high performance liquid chromatography method for the determination of matrine in Lefu oral liquid .Methods The HPLC method was performed on a Diamonsil Platisil NH2 column (4 .6 mm × 250 mm ,5μm) with the mobile phase of acetonitrile-isopropyl alcohol-3% phosphoric acid solution (84 ∶ 4 ∶ 12 ) . The flow rate was 1 .2 ml/min .The sample injection volume was 5 μl .The detective wavelength was 205 nm .Results The calibration curve of matrine showed good linear response ranged from 54 .50 to 872 .00 μg/ml with r=0 .999 1 .The average recovery of spiked samples for matrine was 99 .82% while the relative standard deviation for repetitions was 1 .12% .Conclusion The method was simple ,reliable and repeatable ,which could be used for the quantitative determination of matrine of Lefu oral liquid .
