BACKGROUNDNeuropathic pain results from a lesion or disease affecting the somatosensory system at either the peripheral or central level. The transmission of nociception within the central nervous system is subject to modulation by release and reuptake of neurotransmitters, which maintain a dynamic balance through the assembly and disassembly of the SNARE complex as well as a series of neurotransmitter transporters (inhibitory GABA transporters GAT and excitatory glutamate transporters GT). Neuronal hyper-excitability or defected inhibition involved in neuropathic pain is one of the outcomes caused by imbalanced neurotransmission. SNAP-25, which is one of the SNARE complexes, can modulate the release of neurotransmitters. Glia glutamate transporter (GLT) is one of the two glutamate transporters which account for most synaptic glutamate uptake in the CNS. The role of SNAP-25 and GLT as well as GAT is not clearly understood.

METHODSWe used the rat chronic constriction injury (CCI) model for research, and degraded SNAP-25 by a single intrathecal administration of BoNT/A. The mechanical (MWT) and thermal withdrawal latency (TWL) were tested. The level of SNAP-25, GLT, and GAT-1 were assayed using RT-PCR and Western blotting.

RESULTSSNAP-25 was suppressed by a single intrathecal administration of 0.01U BoNT/A and the reduction of SNAP- 25 was correlated with the relief of nociceptive responses in CCI rats. MWT and TWL returned to normal from the 5th to 14th day (P < 0.05) after the administration. On the 14th day after surgery, compared to the sham group, the upregulation of SNAP-25 in CCI rats was reversed after BoNT/A treatment (P < 0.05). The decreased GLT was reversed after BoNT/A treatment but increased GAT-1 was not influenced by BoNT/A treatment.

CONCLUSIONSSNAP-25 and GLT play important roles in the development of neuropathic pain, and the mechanism may involve the imbalance of neurotransmission after peripheral nerve injury. Intrathecal administration of BoNT/A reversed the upregulation of SNAP-25 and downregulation of GLT after CCI, but had no significant effect on the expression of GAT-1.

OBJECTIVETo obtain the monoclonal antibody against hexon protein of human adenovirus.

METHODSBALB/c mice were immunized with purified recombinant hexon protein, and the spleen cells of the mice were isolated and fused with myloma cells. Four hybridoma cell strains were screened by indirect ELISA and cultured, and the sensitivity, specificity and virus neutralizing activity were analyzed with ELISA, Western blotting and neutralizing test.

RESULTSThe mouse ascites produced by these hybridoma cells contained specific monoclonal antibodies against hexon protein of human adenovirus as identified by ELISA and Western blot, and the antibody generated by 4C6 strain showed human adenovirus type 3-neutralizing activity.

CONCLUSIONThe monoclonal antibodies against hexon protein with high specificity have been successfully obtained, and these antibodies can be useful in developing assays for early diagnosis of HAdV3 infection and also in study of therapeutic drugs of the infection.

OBJECTIVETo investigate the feasibility and safety of the treatment for thoracolumbar fractures with transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach.

METHODSFrom June 2007 to December 2008, 19 cases of thoracolumbar fractures were treated with transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach. There were 7 female and 12 male, ranging from 21 to 57 years of age (mean 40.8 years) at surgery. The time from injury to surgery varied from 1 d to 5 d (mean 2.9 d). Nineteen patients all suffered from single thoracolumbar fracture with the distribution of injury level being T(11) in 1, T(12) in 5, L(1) in 9, and L(2) in 4. According to Denis fracture classification, there were 5 compression fractures and 14 burst fractures. The mean preoperative ratio of the anterior height of the body was 57.2%, kyphosis angle was 17.6° and occupation of spinal canal was 27.7%. The mean preoperative load-sharing classification of spine fractures was 5.2. Based on the ASIA neurologic grading system, preoperative neurological function was grade B in 2 cases, C in 9 and D in 8.

RESULTSMedian operating time was 83.8 min (range 60-95 min) and median blood loss was 133 ml (range 90 - 200 ml). Infection did not occur in any of the patients and the operative incisions were healing well. Average follow-up time was 19.2 months (range 12 - 36 months). At the latest follow-up, the height of the anterior border was corrected to 88.4%, the kyphosis angle was 6.1°, and the occupation of spinal canal was 8.2% on average. The postoperative neurologic function of all 19 patients was improved with grade D in 2 cases and E in 17. There were no instances of instrumentation failure and no patient had persistent postoperative back pain.

CONCLUSIONSTranspedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach could provide reliable neurologic improvement in patients with incomplete neurologic deficit, and could prevent the development of kyphosis.Furthermore, it has the obvious advantages of less invasive and blood loss, and decreases the risks of postoperative lumbodorsal pain.

OBJECTIVETo compare the actions of local thermotherapy with rabdosia liquid and repeated perfusion of mitomycin C for the postoperative prophylaxis of superficial urinary bladder carcinoma.

METHODSIn the prospective non-randomized contemporary controlled study, 123 patients were divided into 2 groups. The patients in group A received local thermotherapy with rabdosia liquid starting from 1-2 months after operation, once tri-monthly for one year. Those in group B received intravesical perfusion of mitomycin C, starting from 2 weeks after operation, once weekly, six times in total, thereafter once monthly for one year. The recurrence rate, disease free interval, and adverse reaction after operation were observed.

RESULTSThe follow-up lasted for 10-45 months with the average of 28.6 +/- 5.8 months. The recurrence rates in group A and B were 5.0% and 14.3%, respectively. Significant difference was shown when compared by Kaplan-Meier analysis of disease free interval and the recurrence rate between the two groups (P < 0.05). The occurrence rates of cystitis, hematuria, vesical contracture, urethral stricture were 28.3%, 5.0%, 1.7%, 1.7%, respectively in group A, 25.4%, 4.8%, 0%, 0%, respectively in group B, showing no significant difference between the two groups (P > 0.05).

CONCLUSIONThe effect of local thermotherapy with rabdosia liquid is reliable in preventing the recurrence of superficial urinary bladder transitional cell carcinoma.

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.

OBJECTIVE: To observe the effect of intrathecal injection of ketamine and clonidine for chronic constriction injury (CCI) in rats. METHODS: Thirty-two SD male rats weighing 220-280 g were anesthetized with intraperitoneal chloral hydrate 300 mg/kg. A catheter was implanted in the subarachnoid space at the lumbal region and CCI rat models were made successfully. On the 4th day after the surgery, the rats were randomly divided into 4 group: a control group,injecting 0.9%NS 20 microL intrathecally; a ketamine group, injecting ketamine 1 mg/kg(20 microL) intrathecally; a clonidine group (CL), injecting clonidine 20 microg/kg (20 microL) intrathecally; a combined ketamine and clonidine group, injecting ketamine 0.5mg/kg and clonidine 10 g/kg (20 microL) intrathecally, once a day for 1 week. BME-410A Plantar Analgesia Tester was used to measured pain threshold before the administration and 30 min after the administration. The rats were killed after the test was finished. And then we detected the nitric oxide synthase (NOS) activity and the NO production in the spinal cord. RESULTS: The combined injection of ketamine (0.5mg/kg)and clonidine(10 g/kg) produced significantly more potent analgesia than the injection of ketamine (1 mg/ kg) or clonidine (20 microg/ kg)alone. The NOS activity and the production of NO in the combined injection group were significantly lower than those of the single injection group (P<0.05). The weight of rats post-administration increased obviously in the 4 groups (P<0.05). CONCLUSION The combined injection of ketamine and clonidine can produce synergistic ab-irritation without obvious side effects.
