Objective To explore a new electrodiagnostic approach using the H reflex elicited by magnetic stimulation of the S1 nerve root and F waves to evaluate sensory nerve root function in patients with S1 radiculopathy.Methods Thirty normal subjects and 30 patients with unilateral S1 radiculopathy were recruited in this study.H reflex and M response were recorded from the bilateral soleus of all the subjects by magnetic stimulation of S1 nerve roots.F and M wave responses elicited by electrical stimulation of bilateral tibial nerves at the popliteal fossa were also recorded.The sensory root conduction time (SRCT) was calculated.Correlations of age and body height with SRCT in the healthy subjects,and between SRCT and pain in the patients with S1 radiculopathy were analyzed.Results The mean values of normal subjects were 3.10 ± 0.44 ms for SRCT,and 0.13 ± 0.19 ms for inter-side SRCT differences.In the 30 patients with S1 radiculopathy,H reflex could not be elicited from 4 patients.Among the remaining patients,the SRCT of the affected side was prolonged significantly (3.90 ±0.65 ms),and the mean value of the inter-side difference increased significantly (0.90 ±0.50 ms).A regression equation correlating SRCT with height was developed,but no significant correlation between SRCT and age in the normal subjects was revealed.There was positive correlation between SRCT and the severity of pain among the patients.Conclusion SRCT can be used as a new electrodiagnostic index in estimating sensory nerve root function in patients with S1 radiculopathy.

Objective To explore the value of a new electrodiagnostic approach for evaluating motor nerve root function in patients with S1 radiculopathy. Methods Thirty healthy subjects and 30 patients with clinical mani-festations of unilateral S1 radiculopathy were recruited. Bilateral compound muscle action potentials evoked by magnetic stimulation of the first sacral nerve root were recorded from the soleus of all the subjects. F wave and M responses to electrical stimulation of the bilateral tibial nerves at the popliteal fossa were also recorded. The peripheral motor conduction time (PMCT) and the motor root conduction time (MRCT) were calculated and compared between the two groups. In addition, needle electromyographic examination (NEE) was performed on the affected side to detect any possible EMG abnormalities. Results The norm established with the normal subjects was 3.45±0.39 ms for the MRCT, and 0.28±0.15 ms for the inter-side difference in the MRCT. In the 30 patients, the mean MRCT and PMCT values on the affected side were prolonged. Of the 23 patients who received NEE, 6 had EMG abnormalities. The agreement between the NEE and MRCT diagnoses was 82.6%. Conclusion MRCT can be used reliably for non-invasive estimation of motor nerve root function and to help diagnose the S1 radiculopathy.

Objective To observe the efficacy and safety of implantation of tissue expanders for large hyperplastic scar on scalp.Methods Between June 2011 and April 2013,a total of 23 patients with large hyperplastic scar received treatment with 31 tissue expanders.The scar size varied from 5.5 cm × 4.0 cm to 17.5 cm ×9.5 cm.The capacity was 50-400 ml for expanders,with the shape of kidney or ellipse.After tissue expansion for 6 to 8 weeks,the expander was removed and hyperplastic scars were resected,followed by the repair of defect with expanded flaps.Further more,the patients received postoperative superficial isotope irradiation after the surgery.Follow-up varied from 6 to 12 months.Results Thirty expanders,except l expander pocket that was removed ahead of time due to infection,were implanted successfully during the whole course of treatment.The main complication was expander exposure in 4 patients,which showed no significant influence on secondary surgery.Twenty patients reported relief of symptoms and achieved satisfactory outcomes,while 3 patients showed great suture tension and experienced delayed stitch removal,followed by the recurrence of hyperplastic scar after the operation.Conclusions The implantation of tissue expanders under the scalp skin is an ideal treatment option for large hyperplastic scar on scalp.Regional suture tension is a direct contributor to the recurrence of hyperplastic scar formation after surgical excision.

Objective:To provide the recommendations for the improvement of drug regulators training system. Methods:The for-eign drug regulator training mode was summarized, the domestic current training mode was analyzed, and some proposals were put for-ward. Results and Conclusion:Compared with more mature foreign training mode, the drug regulator training system in our country was fragmented. We should learn from the foreign experience, and combine with our conditions to improve the drug regulator training system through establishing incentive system, improving the network training and enriching the training mode and so on.

Objective To investigate the effects and partial mechanism of prednisone and TACI-Ig combination on MRL/Mpslac-lpr ( MRL/lpr) mice. Methods MRL/lpr mice were randomly divided into 6 groups, which includ-ed model group, prednisone (2. 5, 5. 0 mg/kg) group, TACI-Ig (15. 0 mg/kg) group, prednisone and TACI-Ig combination [(2. 5+7. 5) mg/kg, (2. 5+15. 0) mg/kg] group. BALB/c mice were set as normal group. Pred-nisone was given intragastrically everyday and TACI-Ig was given subcutaneously every two days for 13 weeks. In the meantime, the normal and model group were treated with an equal volume of normal saline. The general sign and proteinuria level were observed in the treatment period. The sections of spleen and kidney tissues for pathologi-cal analysis were stained with HE. Serum levels of auto-antibodies and BAFF were detected by ELISA kit. The per-centage of plasma cells and CD138 expression in the spleen were detected by flow cytometry analysis and immuno-histochemistry, respectively. Results The skin damage and the proteinuria level were improved and decreased by prednisone and TACI-Ig combination treatment. The spleen and kidney pathology were also improved including re-ducing germinal center formation and alleviating the glomerular fibrosis, mesangial cell hyperplasia and inflammato-ry cell infiltration, respectively. What was more, the percentage of splenic plasma cells ( CD19 -CD138 +) was re-duced significantly, which maybe resulted in the decrease in ANA. However the high level of anti-dsDNA antibody was not influenced by the combination treatment. The serum level of BAFF was also reduced by the combination treatment. Conclusion Prednisone and TACI-Ig combination treatment has a beneficial effect on murine SLE, which may be associated with the inhibition of plasma cell differentiation and the secretion of auto-antibody.
