Objective To study the effect of Licofelone,a novel non-steroid anti-inflammatory drug,on the expression of Fractalkine induced by interleukin-18(IL-18) in mesangial cells.Methods Rat mesangial cells were cultured and divided into IL-18 stimulated group,Licofelone-treated group and normal control group.The cells in IL-18 stimulated group were stimulated by 10 ?g/L IL-18 for 24 h.In Licofelone-treated group,ahead of exposure of IL-18 for 24 h,cells were treated with Licofelone in the doses of 10,50 and 100 ?mol/L for 30 min.Additionally,the mesangial cells without treatment of IL-18 and Licofelone were used as normal control group.Reverse transcription-polymerase chain reaction(RT-PCR) was used to measure the level of Fractalkine mRNA.The expressions of Fractalkine protein in every group were detected with enzyme linked immunosorbent assay (ELISA).Results In normal control group,the expression level of Fractalkine mRNA was 179.0?21.0.After exposure of IL-18 for 24 h,the level of Fractalkine mRNA was 1 220.1?185.7,which was higher than that in normal control group (t=9.646 P

OBJECTIVE: To study the expression of S100B and glial tibrillory acidic protein (GFAP) atter primary brainstem injury in rat and discuss the changes with brainstern injury time and their mechanism in the injury. METHODS: The brainstem injury animal model was established using the mechanical impacting method. The HE staining, Gless argentaffin staining and SP immunohistochemical method were applied to observe the changes of S100B and GFAP at different injury time. The immunostaining results were measured statistically with imaging analysis technology. RESULTS: A large number of S100B positive cells could be seen in 30 min. Afterward, expression increased gradually with time and peaked up in 24 h, and reversed back the normal in 72h. The GFAP positive cells showed rise continually in 30 min, and reached the peak in 48 h, then started to decrease, but still higher than that in control. CONCLUSION The expression of S100B and GFAP is correlated with post traumatic intervals after brainstem injury in rat, and may be useful in estimation post traumatic intervals and nerve regeneration.

OBJECTIVETo observe the clinical effect of Chinese medical (CM) syndrome differentiation based Chinese herbs and recombinant human tumor necrosis factor receptor II-antibody fusion protein (etanercept) for treating ankylosing spondylitis (AS) patients.

METHODSTotally 35 AS patients were treated with syndrome differentiation based Chinese herbs and etanercept. Reinforcing Shen and strengthening Du channel, activating meridians to stop pain was principle used in syndrome differentiation based treatment. Etanercept was subcutaneously injected, 25 mg each time; twice per week for the first three months and once a week for the latter three months. The clinical efficacy was evaluated after 3 and 6 months of treatment. Meanwhile, ASAS20 and ASAS50 standards arriving rates were also observed. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), visual analog score (VAS) for spine pain, VAS for night pain, patient global assessment (PGA), VAS for physician global assessment, CM syndrome score, finger-ground distance, thoracic activity, tragus-wall distance, lumbar scoliosis, cervical rotation, Schober improved test, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were observed before treatment, 3 and 6 months after treatment.

RESULTSCompared with before treatment, BASDAI, BASFI, VAS for spine pain, night pain, physician global assessment, PGA, CM syndrome score, finger-ground distance, thoracic activity, tragus-wall distance, lumbar scoliosis, Schober improved test, ESR, and CRP all decreased after 3 and 6 months of treatment, with statistical difference (P < 0.05). Cervical rotation also decreased after 6 months of treatment, with statistical difference (P < 0.05). Compared with 3 months of treatment, total effective rate of CM syndrome, ASAS20 and ASAS50 standards arriving rates increased after 6 months of treatment, with statistical difference (P < 0.05). There were statistical differences in all indices mentioned above between after 3 months of treatment and after 6 months of treatment (P < 0.05).

CONCLUSIONSyndrome differentiation based Chinese herbs combined etanercept could alleviate inflammatory reaction favorably, control the progression of active AS, and improve joint functions.

OBJECTIVE:To establish an HPLC method for the determination of the content of L-arginine in cefradine for injection.METHODS:The chromatographic analysis was carried on LiChrospher Diol column,and the mobile phase was composed of 0.01 mol?L-1 ammonium dihydrogen phosphate buffer solution(adjusted pH to 2.0?0.1 with phosphoric acid)-acetonitrile(25∶75)at a flow rate of 1.0 mL?min-1;the column temperature was 30 ℃;the detection wavelength was 206 nm,and the sample size was 20 ?L.RESULTS:The linear range of L-arginine was 51.2～307.2 ?g?mL-1(r=0.999 9).The average recovery was 100.7%(RSD=0.6%).CONCLUSION:The method is rapid,accurate and simple,and suitable for the determination of L-arginine in cefradine for injection.

OBJECTIVE:To determine serum concentrations of western medicines in patients treated with "traditional Chinese antiepileptic medicine" alone and to evaluate the curative effects.METHODS:A total of 60 epileptic patients who visited our hospital between Feb.1997 and June 2006 were subjected to plasma drug level monitoring and during which the patients were treated with "traditional Chinese antiepileptic drugs" alone.Plasma concentrations of 4 kinds of western medicin-es were determined by FPIA.RESULTS:Of the 60 cases,valproic acid,carbamazepine,phenytoin and phenobarbitone were detected in 18,40,41,and 47 cases/times,respectively.On average,more than two kinds of western medicines were detected in every patient,and the blood concentrations were mostly beyond effective plasma drug concentration.The total curative effects were unsatisfactory.CONCLUSION:The fact that western medicine ingredients detected in these traditional Chinese antiepileptic medicines is inconformity with medication principle of epilepsy.Traditional Chinese antiepileptic medicines should be used with caution in the clinic in the treatment of epileptic patients.

AIM To study the effect of ketamine on proliferation,cell cycle in the cultured rat neural stem cells. METHODS The growth inhibition of ketamine on neural stem cell was evaluated by an MTT assay. The effect of ketamine on cell cycle was measured by flow cytometry. RESULTS Ketamine inhibited the growth of cultured rat neural stem cells. Flow cytometry analysis showed that G 0/G 1 phase rate was increased but S phase rate was decreased. CONCLUSION Ketamine can inhibit proliferation of cultured rat neural stem cells,and this inhibitition is associated with cell cycle block.
