Objective:To investigate the relationship between hypercoagulable state and the activation of the NF- kappa B pathway,inflammatory/suppression cytokines in patients with osteoarthritis. Methods:56 patients with OA were divided into two groups according to random number table:XFC group ( 28 cases ) and glucosamine ( GS ) group ( 28 cases ) . Two groups were treated for 3 months. Nine healthy people are healthy control group ( NC) . Determining the expression levels of the index of the NF-κB signaling pathway (p50,p65,TAK1,IκBα) and TNF-α,IL-1,IL-10,platelet activating factor(PAF) in serum by enzyme-linked immunosorbent assay. Detected the level of the indicators and laboratory indexes related with coagulation,observed the changes between the two group, used OA symptoms integral scale, LequesneMG, SF-36 and vas to assess efficacy;and made a correlation analysis. Results: After treatment,FIB,D-D, PAF, PLT, p50, p65, TAK1, IL-1, TNF-α, hs-CRP, ESR, IgG, LequesneMG, symptom integral meter, and VAS integral were significantly higher,APTT,PT,PAF-AH,IL-10 and each dimension integral of SF-36 significantly decreased in 2 groups (P<0. 05). XFC group was better than the GS group in reducing the level of PLT,FIB,TNF-α,p65,TAK1,hs-CRP,ESR,symptom integral meter,and VAS integral and increasing PT,each dimension integral of SF-36, etc (P<0. 05,P<0. 01). The results of Pearson correlation analysis show that PLT,FIB,D-D,PAF had positive correlation with p50,p65,TAK1,IL-1,TNF-α,hs-CRP,ESR,IgG,Le-quesneMG,symptom integral meter,and VAS integral,and negative correlation with IL-10 and each dimension integral of SF-36 ( P<0. 05,P<0. 01). PT had positive correlation with IL-10,GH and PF,and negative correlation with p50,p65,TAK1,IL-1,TNF-α,hs-CRP,ESR,IgG,symptom integral meter,and VAS integral (P<0. 05,P<0. 01). Conclusion: XFC could inhibit the NF-κB signaling pathway, raise the level of IL-10, reduce the expression of IL-1, TNF-α, P50, p65, TAK1 and so on, and reduce the abnormal inflammatory immune response. So as to achieve the purpose of delaying and inhibiting the production of hypercoagulable state,reduce joint disease,relieve the symptoms of joint pain and stiffness,eventually improve the patient’s quality of life.

Objective To investigate the effect of rocuronium on spectral entropy during induction of general anesthesia in patients of Uygur nstionality. Methods Forty ASA Ⅰ or Ⅱ patients (Uygur nationality) of both sexes, aged 20-50 yr, weighing 45-70 kg, undergoing elective surgery under general anesthesia, were divided into 2 groups ( n = 20 each): normal saline (NS) group and rocuronium group (group R). Anesthesia was induced with target-controlled infusion of propofol. The initial target plasma concentration wan net at 2 μg/ml. The concentration wan then increased by 0.5 μg/ml every 4 min until response entropy (RE) was decreased to 45 and maintained for 4 min. When the plasma concentration was equal to the effect-site concentration, iv rocuronium 0.6 mg/kg was injected in group R, while group NS received the equal volume of NS instead. Fentanyl 3 μg/kg was injected intravenously at 3 min after recuronium administration. The patients were tracheal intubated and mechanically ventilated. State entropy (SE) and RE were recorded immediately before induction (baseline, To), before rocuronium administration (T1), 2 main after rocuronium administration (T2) and at 0, 1, 2 and 3 min after intubation (T3-6). The difference between RE and SE wan calculated. Results The RE value at T3 and T4 and the difference between RE and SE at T2.5 were significantly lower in group R than in group NS ( P < 0.05). Conclusion Rocuronium can decrease the RE value and degree of increase in the difference between RE and SE during induction of general anesthesia in patients of Uygur nationality, which may affect the accuracy of spectral entropy in monitoring the depth of anesthesia.

Objective To analyze the influence of adenovirus latent infection on gamma-glutamylcysteine systhetase(γ-GCS) in rat alveolar epithelial cells. Methods The rat alveolar epithelial cells were stably transfected with the plasmid pE1Aneo and control plasmid. Glutathione(GSH) contents, the activity of γ-GCS were detected in oxidant stress. Then the leuel of protein expression, mRNA expression, and promoter transcriptional activity of glutamate-cysteine ligase catalytic subunit(GCLC) were further detected. Results GSH contents decreased because of adenovirus E1A expression in oxidant stress. E1A repressed the expression and activity of γ-GCS, messenger RNA expression, and promoter transcriptional activity of GCLC. Conclusion Adenovirus E1A decreased the activity of γ-GCS probably by repressed promoter transcriptional activity of GCLC. As a result, GSH contents were downregulated in oxidant stress. Thus Adenovirus latent infection amplified the oxidant/antioxidant imbalance in rat alveolar epithelial cells in oxidants stress, which may be an important mechanism of COPD.
