In recent years, neuro-electrophysiological techniques, as objective evaluation methods, have been gradually used in func-tional evaluation, guiding clinical rehabilitation programs and judging prognosis after stroke. They were proved to judge the integrity of cen-tral nervous system and conduction function and evaluate neuromuscular function. Nerve conduction, needle electromyography, H reflex, F wave, sympathetic skin response, motor-evoked potentials, somatosensory-evoked potentials, brain stem auditory-evoked potentials and sur-face electromyography were reviewed in this article.

Objective To investigate the effects of ulinastatin(UTI)on the nerve regeneration of mice experimental allergic encephalomyelitis and the expression of related factors and protein.Methods Forty mice were randomly divided into four groups:ulinastatin group(U),atorvastatin group(A), empty control group(C)and normal control group(N).The experimental autoimmune encephalomyelitis(EAE)in mice was constructed by Freund's complete adjuvant and MOG35-55 polypeptide.Histopathological changes were observed by HE,LFB and Bielschowsky stained at the 3rd week and 4th week after immunized of each group.The expressions of CD4 +T cells were estimated by immunohistochemical method.The expression of myelin basic protein (MBP),brain-derived neurotrophic factor(BDNF),growth associated protein-43(GAP-43),2',3'-cyclic nucleotide-3'-phosphodiesterase(CNP)were detected by Western-blot.Results The largest neurological score of group U was lower than group C,and the difference was statistically significant(P<0.05 ).Pathological features showed that the inflammatory cells,demyelination of spinal cord and axonal injury of group U were lighter than group C.With the duration of treatment,nerve injury decreased.After UTI treatment,the expression of MBP,BDNF,GAP-43,CNP increased.They were statistically significant difference when compared with group C(P<0.05).There was no significant difference between ulinastatin and atorvastatin in the treatment of EAE.Conclusion Ulinastatin could reduce the extent of nerve damage effectively and promote its regeneration which provide a theoretical basis for the clinical treatment of MS.

Objective To explore the changes in secondary lesions to motor neurons caudal to a damage site on the spinal cord of rats.MethodsForty female adult Sprague-Dawley rats were given incomplete spinal cord injuries (SCIs) at the T10 level using a modification of Allen's method. Locomotor function was evaluated using an inclined plane test, modified Tarlov scores and the Basso-Beattie-Bresnahan (BBB) scale before the operation and 1,2, 3,4 and 5 weeks post surgery. Histomorphological changes at T10 and L5 were observed under a light microscope.Results①Morphology of the distal spinal cord: 1 week after SCI, neurites and Nissl bodies of the motor neurons had decreased. By the 2nd week the decrease had become more obvious. At the 3rd week after SCI, neurites and Nissl bodies had not decreased further, but neuron atrophy and apoptosis were found. At the 4th to the 5th week after SCI, neurites and Nissl bodies had increased significantly. ②Morphology of the damage site: At the 1 st week after SCI, hemorrhage and inflammation as well as nerve fiber necrosis were observed. By the 2nd week astrocytes had-increased and a few nerve fibers had grown at the damage site. At the 3rd week, regeneration of nerve fibers and astrocytes were found. At the 4th to the 5th week after SCI astrocytes and nerve fibers had not increased further. ③Locomotion function: The angles of the inclined plane test, Tarlov scores and BBB scores had decreased significantly at the 1st, 2nd, 3rd, 4th and 5th week post injury compared with those before the SCI. The values at the 2nd, 3rd, 4th and 5th week were all significantly better than those at the 1st week after SCI. There was an increasing trend in scores from the 3rd week to the 5th week, but without significant differences compared with the 2nd week after the operation.ConclusionsSecondary degeneration and damage, including decreases in neurites and Nissl bodies, neuron atrophy and apoptosis may occur in the motor neurons distal to the damage site in the early stage after SCI. This correlates with changes in the pathology of local damage.

Objective To investigate the clinical efficacy and safety of recombinant tissue type plasminogen activator(rr-PA) and urokinase(UK) in the treatment of acute myocardial infarction (AMI).Methods According to the digital table,128 patients with AMI were randomly divided into two groups,64 cases in each group.The control group adopted UK intravenous thrombolytic therapy,while the observation group adopted rr-PA intravenous thrombolytic therapy.The recanalization condition at different time after thrombolytic therapy,the incidence rate of cardiovascular events and death rate were compared between the two groups.Results The recanalization rate at 30min,60min and 120min after thrombolysis of the observation group were 29.69 ％,59.38 ％ and 93.75 ％,respectively,which were significantly higher than 14.06％,35.94％ and 68.75％ of the control group(x2 =6.34,7.01,7.45,all P ＜ 0.05) ;The incidence rate of cardiovascular events and mortality rate of the observation group after thrombolytic therapy were 17.19％ and 4.64％,respectively,which were significantly lower than 40.63％ and 12.50％ of the control group (x2 =7.83,7.62,all P ＜ 0.05).Conclusion Recombinant tissue type plasminogen activator intravenous thrombolytic therapy has significant effect in the treatment of acute myocardial infarction after thrombolysis,which can reduce the incidence of cardiovascular events and mortality,with good clinical application value.

Objective To develop a HPLC-MS/MS methodfor determination of cyclosporin A(CSA)and AM1 in bone marrow transplant patient,and explore the relationship of CSA and its main metabolite AM1 within individual and between individuals,and provide reliable basis for clinical rational use of monitoring in CSA blood drug concentration.Methods CSD was used as internal standard,and whole blood samples were treated with internal standard methanol precipitated protein.The column was Ultimate XB-C18 with a column temperature of 65 ℃ and the mobile phase was eluted with 0.1％ of formic acid and 2 mmol/L ammonium acetate in water and methanol containing 0.1％ formic acid.The mass spectrometry was detected by electrospray ion trap positive ion mode,MRM scanning,monitoring CSA 1219.9 to 1203.1 m/z,AM1 1236.1 to 1219.1 m/z,CSD 1234.0 to 1217.0 m/z.Results The concentration of CSA was linear in the range of 16 to 1600 ng/mL,Y=0.0143X+0.0213(r=0.9976).The concentration of AM1 was linear in the range of 10～1000 ng/mL,Y=0.00363X-0.00528(r=0.9973).The ratio of CSA to AM1 (AM1/CSA) between individual ranged from 32％ to 356％.The ratio of CSA to AM1 within indiviolual(AM1/CSA) ranged from 27 ％ to 147 ％.Conclusion HPLC-MS/MS method for the simultaneous detection of CSA and AM1 was established.The variation of CSA exists in the bone marrow transplant patient between individuals and within individual;the HPLC-MS/MS method can be used for monitoring of whole blood concentration of CSA in bone marrow transplant patients.
