Objective To investigate the effects of resveratrol on epileptic seizure and cognitive impairment and the role of CREB in rats with temporal lobe epilepsy (TLE). Methods TLE rat model was established by LiCl?pilocarpine injection and resveratrol was administrated at a dose of 15 mg/(kg · d) for 7 days. The rat behavior was evaluated by Racine scale and the CREB expression and phosphorylation in temporal cortex were detected with western blot. The Morris water maze was used to assess the learning and memory. Results Resveratrol administra?tion significantly reduced the Racine scales of TLE rats. The CREB phosphorylation in TLE group was increased compared with that in control group, which was remarkably inhibited by resveratrol. The escape latency of TLE group was increased at 4th, 5th and 6th day after training, and time in target quadrant was reduced compared with that in control group. Resveratrol significantly decreased latency time and increased target quadrant time of TLE rats. Conclusion In TLE rats, resveratrol administration suppresses epileptic seizure and improves cognitive function, which might be mediated by inhibition of CREB phosphorylation.

Objective To study the effect of volatile chemicals in the air of newly decorated rooms on O6-methylguanine-DNA methyltransferase (MGMT) expression in the lung, liver, kidney and testicle tissues of mice. Methods Forty Kunming mice were randomly divided into four groups and the imitate pollutants mixture of volatile chemicals in the air of newly decorated rooms was used as the exposed toxicants: low-dose exposure group (7.5 mg/m3), moderate-dose exposure group (15 mg/m3), high-dose exposure group (30 mg/m3), the control group (no exposure ). The mice were exposed 4 hours each day, for nine weeks. Streptavidin and biotechnology-peroxidase (SABC) immunohistochemical method was used to determine the MGMT expression in the lung, liver, testicle and kidney tissues. Results The expression of MGMT in the liver, lung, testicle tissues in the high, moderate and low-dose groups reduced significantly compared with the control group (P0.05). Conclusion The higher exposure of volatile chemicals from the air of newly decorated rooms may inhibit the MGMT expression in the liver, lung and testicle tissues of mice.

Objective To assess the epidemiological relatedness on an outbreak of Enterococcus facium sepsis between humans and pigs based on genomic analysis. Methods Two bacterial isolates recovered randomly from the blood of one patient and one pig were analyzed for homogeneities by comparison with 16S rRNA gene sequences in the GeneBank. Moreover, The extracted genomic DNA was digested with the 20 U SamI enzyme respectively, then their interrelationship was performed according to the pulsed field gel electrophoresis. Results Sequences determined from both human and pig isolates were 100% identical and most closely related to E. facium , diverging from the prototype sequence by one nucleotide (99.9% similarity) and displayed indistinguishable pulsed field gel electrophoresis patterns. Conclusions These data demonstrate epidemiological relatedness of the bacterial isolates, and suggest spread of an E. facium -related sepsis outbreak from pigs to humans.

Objective To evaluate influence of patient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia (PCEA) on expressions of serum inflammatory cytokines in elderly patients with hemi or whole hip replacement using cemented artificial joint. Methods Elderly patients undergoing hip replacement were selected and were divided into PCIA group and PCEA group. VAS scores were calculated at 12 h postoperatively. Patients whose VAS scores were not more than 2 at postoperative 12h were included. 30 cases in each group were finally included. Fifteen cases were randomly chosen in each group and underwent sample blood drawing for assays. Expressions of serum inflammatory cytokines were detected by ELISA , RT-PCR and Western-blot. Results Gene and protein expressions of TNF-a as well as IL-6 in group PCEA were lower and expression of IL-10 was higher than that in group PCIA. Serum level of TGb-β was higher in group PCEA detected by ELISA. There was no significant difference in expression of IL-8 between groups. Conclusions PCEA may better promote expressions of anti-inflammatory cytokines and inhibit expressions of proinflammatory cytokines. PCEA is superior in maintenance of inflammatory cytokine balance.

BACKGROUND: Functional magnetic stimulation (FMS) is characterizedby safe, unwounded and non-side effect. At present, it has been used incentral nervous conduction, recovery from nervous exhaustion, bone healing, treatment of neural disorder, research of brain function, and so on;meanwhile, it also can improve urination dysfunction.OBJECTIVE: To pursue investigating the effect of FMS on the treatment of neurogenic bladder.DESIGN: Self controlled study pre- and post-treatment.SETTING: Department of Rehabilitation Medicine, Tongji Hospital,Tongji Medical College, Huazhong University of Science and Technique.PARTICIPANTS: Twenty patients with neurogenic bladder were recruited in the Department of Rehabilitation Medicine, Tong ji Hospital, Tongji Medical College, Huazhong University of Science and Technique from June 2003 to June 2004. Of them, 12 patients with neurogenic bladder were caused by spinal cord injury and 8 by other reasons under urinary dynamic examinations.METHODS: Twenty patients with neurogenic bladder underwent S3 never root and bladder FMS by MagLite magnetic stimulation system (Dantec Company, Denmark), for 20 successive times, twice a day, five days a week and 4-6 weeks as a course. The interval was 2 seconds and the frequency was 5 minutes for once. Parameters were designed as the following: intensity: 70％-80％maximal magnetic intensity; frequency: 5 Hz; impulse length: 1 ms.MAIN OUTCOME MEASURES: Parameters were observed pretreatment, post-treatment immediately and at 1 and 3 months: ① Urine frequency: the mean voided volume and the maximal voided volume; ②Scores of quality of life (QOL): Scores ranged from 0 to 6 points. The higher the scores were, the poorer the QOL was. ③ International lower urinary tract symptoms (LUTS) scores: There were 7 questions with the scores of 0-35. The higher the scores were, the severer the symptoms were.RESULTS: All 20 patients were involved in the final analysis. ① Effect of urination on QOL scores: Scores were decreased post-treatment as compared with those pretreatment (3.17±1.53, 4.58±1.00, P ＜ 0.01), and scores were increased within 1 and 3 months post treatment but were still lower than those pretreatment (P ＜ 0.01). ② LUTS scores: Scores were decreased post-treatment as compared with those pretreatment (21.42±5.00,28.08±1.51, ,P ＜ 0.01), and scores were increased within 1 and 3 months post-treatment but were still lower than those pretreatment (P ＜ 0.01). ③Times of urination were decreased, but the mean voided volume and themaximal voided volume were increased (P ＜ 0.05); in 1 month post-treatment, each parameter was decreased but was still superior to that pretreatment (P ＜ 0.05); at 3 months post-treatment, each parameter was still decreased, but there was no significant difference of mean voided volume from that pretreatment (P ＞ 0.05), and other parameters were superior to those pretreatment (P ＜ 0.05); there was no significant difference at eachtime point post-treatment (P ＞ 0.05).CONCLUSION: FMS can partly improve the symptoms of voiding dys-function and improve the quality of life.

AIM: To investigate the molecular mechanism of microRNA-21 (miR-21) in the regulation of Schwann cell proliferation following nerve injury.METHODS:The expression of miR-2l was detected by real-time PCR. Synthetic miR-21 mimic and its control were transfected into rat Schwann cells.CCK-8 assay was performed to evaluate the influence of miR-21 on the proliferation of Schwann cells.The cell cycle distribution was determined by flow cytometry. The expression of transforming growth factorβ-induced protein ( TGFBI) and cyclin D1 were detected by Western blotting. RESULTS:The expression of miR-21 in model group was 7.87 ±0.75 and 7.75 ±0.80 times higher than that in sham operation group and blank group respectively.After transfected with miR-21 mimic, the expression of miR-21 in experimen-tal group was 2.21 ±0.14 and 2.29 ±0.21 times higher than that in negative control group and blank group respectively. Moreover, the A450 value of CCK-8 assay in experimental group at 48 h was higher than that in negative control group and blank group.The proliferation index in experimental group was higher than that in negative control group and blank group. At the same time, the expression of TGFBI obviously decreased and the cyclin D1 increased in the Schwann cells 48 h after transfection with miR-21.CONCLUSION:miR-21 promotes the proliferation activity of Schwann cells by down-regulating TGFBI expression.
