Objective To investigated the analgesic effect of processed Aconiti tuber(PAT) in rats with a sciatic nerve chronic constriction injury(CCI) .Methods The study was conducted in two parts. CCI model was developed with four ligatures placed around the right sciatic nerve and tied without obstructing the blood supply of the nerve. In part Ⅰ, forty rats were randomly divided into five groups(n = 8) . In group Ⅰ normal saline 1 ml , In group Ⅱ-Ⅴ PAT 0.5 ,1, 2 ,or 4 g/kg was administered orally 14 days after CCI respectively. In part Ⅱ , thirty-two rats were randomly divided into four groups (n = 8) . In group Ⅰ oral normal saline 1 ml, in group Ⅱ oral PAT 2 g/kg, in group Ⅲ oral PAT 2 g/kg + intraperitoneal nor-binaltorphimine (nor-BNI) 2 mg/kg, in group Ⅳ oral PAT 2 g/kg + intrathecal nor-BNI 100 ?g was administered 14 days after CCI. As indicators of mechanical and heat hyperalgesia, the paw withdrawal pressure threshold (PWPT) in response to a graded pressure stimulus with a filament and the paw withdrawal latency (PWL) in response to radiant heat were measured in both hind paws before and after drugs administration.Results In part Ⅰ, in group Ⅲ-Ⅴ PWL was prolonged significantly and in group Ⅳ - Ⅴ PWPT were significantly increased compared with those in group I . There was no significant difference in PWL and PWPT between group Ⅰ and group Ⅱ . In part Ⅱ , in group Ⅲ, Ⅳ PWPT and PWL were significantly lower than those in group Ⅱ . There was no significantly difference in PWL and PWPT between group Ⅰ and group Ⅲ, Ⅳ . Conclusion In rat with neuropathic pain processed Aconiti tuber exerts analgesic effect via the spinal ?-opioid receptor activation.

Objective To investigate the pharmacodynamics and pharmacokinetics of ropivacaine for epidural anesthesia in renal transplantion. Methods Eight patients undergoing renal transplantation (group R) and eight patients with normal renal function (group C) were included in this study. Nine patients were male and seven female. Age ranged from 27-52 years and body weight from 46-89 kg. Radial artery was cannulated under local anesthesia for blood pressure monitoring and blood sampling. An epidural catheter was placed at L1-2. An epidural bolus of 0.75% ropivacaine 16 ml was given. The level of sensory block was tested every 3 min within 30min after epidural ropivacaine and then every 15 min.The degree of motor block was assessed using Bromage score every minute (0 = the patient can move his/her lower limb freely, 3 = the patient can not flex his/her hip, knee and ankle) . Arterial blood samples were taken before, during and after surgery for determination of plasma concentration of Alphal acid glycoprotein (?1-AGP) using an ultrafiltration technique. Results Demographic data including gender, age and body weight were comparable between the two groups. The onset time of sensory block in group R (20.00?4.63)min was significantly shorter than that in group C (32.14?8.09) min, while duration of sensory block in group R (60.00?27.69) min was significantly tonger than that in group C (43.13 ? 27.64) min. Plasma concentration of ?1-AGP in group R was significantly higher than that in group C ( P

BACKGROUND:Preliminary studies have showed that vacuum sealing drainage based on wound surface dressing biomaterials is a good method to cover the wound as succedaneous peau when the soft tissuedefects along with open fracture cannot be completely repaired during the first operation. OBJECTIVE:To explore the efficacy of vacuum sealing drainage based on wound surface dressing biomaterials in repair of soft tissue defects of foot and ankle. METHODS:Fourteen patients with soft tissue defects of foot and ankle were treated using free skin graft combined with vacuum sealing drainage technique. Meanwhile, the traditional skin graft after wound dressing changes was applied in another 11 patients. The clinical outcomes were compared between two groups. RESULTS AND CONCLUSION:The transplanted skin in 10 cases of the vacuum sealing drainage group survived. The total survival rate was 71%, and surgical dressing change was applied in the left four patients to finaly cover the wound. By comparison, the transplanted skin in four cases of the traditional group survived. The total survival rate was 54%. To finish the wound, three of the left patients were turned to surgical dressing change and two of them stil needed skin graft operation once more. The total survival rate between the two groups has no statistical significance(P > 0.05). The therapeutic procedure noted that the time waiting for the secondary surgical visit, times for dressing change before the second intervention and the time for final union between the two groups were statisticaly different (P < 0.05). So the vacuum sealing drainage based on wound surface dressing biomaterials may accelerate the repair of soft tissue defects of foot and ankle when using the free skin graft operation.

The medical students, Shanghai Jiaotong University School of medical from 5- year,7-year, 8-year to general of academic, received evidence-based medicine (EBM) education. The students' background and attitudes about EBM were different. Teaching EBM should pay attention to the relationship of EBM and basic courses, especially for deferent students. Teaching EBM should transform from imparting basic knowledge to learning skills on their own initiative.

ObjectiveTo investigate the effects of caffeine citrate (CC) on the neuronal proliferation and apoptosis and long-term learning ability in neonatal rats with hypoxia-ischemic brain damage (HIBD).MethodsForty-eight 7-day-old Sprague-Dawley neonatal rats were randomly divided into 3 groups: sham operation group (n=16), HIBD group (n=16), HIBD + caffeine citrate group (CC group,n=16). Rats in HIBD and CC groups received ligation of left common carotid artery followed by 2 hours of hypoxia to establish HIBD model. Rats in CC group were injected intraperitoneally with CC (20 mg/kg) before and at 0 min, 24 h, 48 h, and 72 h after hypoxia-ischemic (HI), and rats in the other two groups were injected intraperitoneally with an equal volume of normal saline at the corresponding time. Meanwhile, from postnatal day 10, each rat was injected intraperitoneally with 5-bromo-2’-de-oxyuridine (BrdU) (50 mg/kg) for 5 consecutive times, once every 12 h. On postnatal day 12, BrdU in the hippocampal dentate gyrus and cleaved caspase-3 in the hippocampal CA1 area were detected by immunohistochemistry, and neuronal apoptosis in hippocampal CA1 area were detected by TUNEL staining. On postnatal day 28, long-term learning and memory ability of rats was tested by Y maze.ResultsThere was signiifcant difference in the number of BrdU-positive cells in brain tissues of rats among three groups (F=101.38,P<0.01). The BrdU-positive cells in HIBD group and CC group were signiifcantly more than those in sham operation group (P<0.05). There was signiifcant difference in the number of cleaved caspase-3-positive cells in hippocampal CA1 area among three groups (F=379.77,P<0.01). The cleaved caspase-3-positive cells in CC group were signiif-cantly fewer than those in HIBD group but signiifcantly more than those in sham operation group (P<0.05). The TUNEL-pos-itive cells in hippocampal CA1 area were signiifcantly different among three groups (F=505.92,P<0.01) which was most in HIBD group and fewest in sham operation group and signiifcant difference was found through multiple comparison (P<0.05). The total learning number of avoiding electric shock tested by Y maze was signiifcantly different among three groups (F=32.05, P<0.01) which was most in HIBD group. Correct response rate was significantly different among three groups (F=24.99, P<0.01) which was lowest in HIBD group.ConclusionsCaffeine citrate can improve the ability of long-term learning and memory in neonatal rats with hypoxia-ischemic brain damage, the mechanism of which may be related to reducing the neuronal apoptosis after hypoxia ischemia.
