Objective To study the changes in the polyol pathway of glucose metabolism and oxidative stress responses induced by general thoracic surgery by measuring erythrocyte aldose reductase (AR), phosphofructokinase (PFK) and glucose-6 phospate dehydrogenase (G-6PD) activities and plasma MDA and GSH levels before and after surgery performed under different anesthetic techniques. Methods Thirty-two ASA Ⅰ-Ⅱ patients aged 45-71 yrs weighing 55-70 kg were randomly allocated to one of two groups with 16 patients in each group : group Ⅰ received isoflurane inhalation for maintenance of anesthesia and group Ⅱ isoflurane inhalation combined with epidural block. Patients with endocrine and glucose metabolism-related diseases were excluded. The patients were premedicated with intramuscular phenobarbital 0.1 g and atropine 0.5 mg. Anesthesia was induced with intravenous midazolam 0.1 mg?kg-1 , propofol 1.0-1.5 mg?kg-1 , fentanyl 0.1-0.15 mg, droperidol 1-2 mg and vecuronium 0.1 mg?kg-1 in both groups. The patients were mechanically ventilated (VT 8-10 ml?kg-1, RR 10-12 bpm) after tracheal intubation. Anesthesia was maintained with isoflurane inhalation at 1.2-1.6 MAC in group Ⅰ or isoflurane inhalation (0.6-0.8 MAC) combined with epidural block (T9-10) with 1 % lidocaine in group Ⅱ supplemented with fentanyl 5-10 ?g?kg-1 and droperidol 0.1-0.2 mg?kg-1 in divided doses and vecuronium infusion at 1-2 ?g? kg?min-1 . Venous blood samples were obtained before anesthesia (baseline, T0), 90 min after skin incision (T1), 60 min after surgery (T2 ) and on the 1 st and 2nd postoperative days (T3 , T4 ) for determination of erythrocyte AR, PFK and G-6PD activities and plasma glucose, MDA and GSH levels. Results In group Ⅰ plasma MDA level and AR and G-6PD activities in erythrocyte were significantly increased, while plasma GSH level and PFK activity in erythrocyte were significantly decreased on the 1st postoperative day compared to the baseline values before anesthesia (T0) (P 0.05). Conclusion Isoflurane inhalation combined with epidural block can effectively attenuate the effects of surgical trauma on glucose metabolism in theerythrocyte and the oxidative stress responses of the body.

Objective To investigate and compare the effects of pretreatment with different concentrations of trarnadol and morphine on the differentiation of hunan helper T cells (Th) in vitro. Methods Fifteen ASA Ⅰ patients of both sexes (8 males, 7 females) aged 23-59 yrs scheduled for minor day-care surgery were enrolled in this study. The patients had never taken morphine and tramadol before. Blood samples were taken from peripheral vein. Whole blood and mononuclear cells isolated from peripheral blood (PBMCs) were incubated with morphine 10, 100 or 1000 ng?ml-1(group M1 , M2 , M3) or tramadol 50, 500, 5000 ng?ml-1(group Q1, Q2, Q3) for 24 h. Then irrntants was added and incubated for another 5 or 24 h. In the whole blood the level of IL-2 and IFN-?(as markers of Th1 cells) and IL-4 and IL-10 (as markers of Th2 cells) were determined using three-color flow cytometry. In PBMCs the expression of CD4+ and CCR5+ (as markers of Thl cells) and CD4+ and CCR3+ (as markers of Th2 cells) were determined. The Th1/Th2 ratio was calculated. Results Pretreatment with morphine or tramadol significantly increased the number of Th2 cells while the number of Thl cells significantly decreased both in a dose-dependent manner leading to a significant decrease in Th1/Th2 ratio. Conclusion Tramadol and morphine can inhabit in vitro the cellular immune function in dose-dependent manner. The immunosuppressive effect of tramadol is less than that of morphine.

Objective:To establish the quality standard for infantile bronchitis traditional Chinese medicine lotion. Methods:TLC was used for the qualitative identification of Ephedra herba, Paeonia lactiflora Pall. , Poria cocos, Fructus aurantii and Epimedium brev-icornu Maxim. . HPLC was used for the content determination of ephedrine hydrochloride, pseudoephedrine hydrochloride and paeoni-florin. The chromatography conditions for ephedrine hydrochloride and pseudoephedrine hydrochloride were as follows: an AElichrom Pdar-Phenyl Polyphenyl ether-bonded phenyl-bonded silica column (250 mm × 4. 6 mm, 5μm) was used, the mobile phase was aceto-nitrile-0. 2% phosphoric acid solution (1 :99), the flow rate was 1. 0ml·min-1, the detection wavelength was 210 nm, the column temperature was 30℃ and the injection volume was 10 μl. The chromatography conditions for paeoniflorin were as follows:an Inertsil ODS-3 C18 column (250 mm × 4. 6 mm, 5 μm) was used, the mobile phase was acetonitrile-0. 1% phosphoric acid solution (15:85), the flow rate was 1. 0 ml·min-1, the detection wavelength was 230 nm, the column temperature was 30℃ and the injection vol-ume was 10 μl. Results:The TLC results of Ephedra herba, Paeonia lactiflora Pall. , Poria cocos, Fructus aurantii and Epimedium brevicornu Maxim. showed clear spots with good resolution. Ephedrine hydrochloride, pseudoephedrine hydrochloride and paeoniflorin had a good linear relationship within the range of 10.11-101.10 μg·ml-1(r=0.9996), 10.08-100.80 μg·ml-1(r=0.9991) and 20.50-102.5 μg·ml-1(r =0.9996), respectively. The average recovery was 98.80% (RSD =1.87%, n =6), 98.77%(RSD=1. 72%, n=6) and 99. 57% (RSD=1. 56%, n=6), respectively. Conclusion: The established quality standard can be used for the quality control of infantile bronchitis traditional Chinese medicine lotion.

[Objective]To observe the effect of opposing needling accompanying continual static stretch(CSS) on high-spasticity poststroke.[Methods]80 patients with high spasticity poststroke were randomly divided into four groups.A group:treated with opposing needling accompanying CSS;B group:treated with opposing needling;C group:treated with CSS;D group:acupoints selected from anti-spasm muscle.The therapeutic effect of the four methods was evaluated on proving spasm degree and motor function.[Results]Four methods had effect on high muscle tension in patients poststroke.The marks of Ashworth scale and Fugl-Meyer scale of the four groups had remarkable difference(P

Objective: To investigate the effects of preconditioning with lithium on the expressions of HSP70 in gerbil after global ischemia. Methods: The transient ischemia model of gerbil global was established by clamping the bilateral common carotid arteries for 5 min.36 gerbils were randomly divided into group lithium(n=18) and group control(n=18).Gerbils in group lithium were injected with lithium intraperitoneally,5 mmol/kg,once a day for 5 consecutive days.Normal saline was used instead of lithium in group control as vehicle control.Both group lithium and control underwent ischemia after preconditioning,and were then further divided into three subgroups(n=6,in each subgroup).The garbles in lithium 1 or control 1 subgroup were sacrificed 1 day after ischemi;lithium 3 or control 3 sacrificed in 3 days;and lithium 7 or control 7 were sacrificed in 7 days.The brains were made into paraffin sections and were used for immunohistochemistry against HSP70. Results: Compared with the vehicle control,the HSP70 expression in subgroup lithium1 was inhibited in the hippocampus CA1(P

Objective: To investigate the effect of morphine dependence and withdrawal on the levels of neurosteroids in hippocampus of male rat.Methods: Rats were given (ip) increasing doses of morphine to form morphine physical dependence, withdrawal syndromes were precipitated by naloxone. The conditioned place preference (CPP) was used to establish morphine psychological dependence. The concentrations of dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), pregnenolone (PREG), pregnenolone sulfate (PREGS), and allopregnanolone (AP) in rat hippocampus and plasma were quantified by liquid chromatography-mass spectrometry. Results:The rat model of morphine physical and psychological dependence were successfully established by ip increasing doses of morphine for 7 days and 5mg?kg~ -1 morphine for 10 days respectively. Compared with saline control group, morphine physical dependence increased DHEA and PREG contents in rat hippocampus (0.88?0.19/0.67?0.17,t=2.52,10.94?2.02/7.53?2.64,t=3.24,P
