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 evaluate the diagnostic value of multislice CT(MSCT)in multilocular cystic real cell carcinoma(MCRCC).Methods Imaging features of 22 patients with MCRCC proved by histopathologic examinations,these patients were underwent non-enhanced and dual-phase contrast-enhanced CT scans and evaluated CT signs.Results 22 tumors all appeared as well defined multilocular cystic mass.The cystic wall presented with irregular thicking in 14 cases and regular thicking in 8 cases.The tumors with thin coarse septum in 6 cases(the transverse diameter ≤2 mm),irregular thicking septum in 11cases(2mm ＜the transverse diameter ≤ 5 mm)and septum with nodule in 5 cases(the transverse diameter ≤ 5 mm).Cystic wall and septum enhancement were detected with dual-phase contrast-enhanced CT.Cystic ares and hemorrhagic areas and calcification were no enhanced.Calcification of cystic wall were found in 2 cases and cyst in 3 cases.Conclusion MSCT imaging appearances have typical features.It has great important value in the preoperative diagnosis of MCRCC with non-enhanced and dual-phase contrast-enhanced CT scans.

Objective To investigate operation time on biliary duct stone with acute gallstone pancreatitis.Methods The clinical data of 44 patients with acute gallstone pancreatitis who were admitted to Department of General Surgery,Taicang First People's Hospital for surgical management from January 2011 to December 2013 were retrospectively analyzed.Patients were divided into early surgery group and delayed surgery group according to the timing.Early surgery group was defined as the patients whose symptoms of pancreatitis were basically disappeared after conservative treatment and surgery was performed within two weeks,while delayed surgery group was defined as the patients who underwent surgery after two weeks.Results Of the 44 acute gallstone pancreatitis cases,18 patients were males,and 26 were females,with median age of 54 years old (range 26-83 years old).Forty-two cases were mild acute pancreatitis and the other two cases were severe acute pancreatitis.Preoperative imaging indicated both cholecystolithiasis and choledocholithiasis in 5 patients,cholecystolithiasis alone in 39 patients.The 5 patients underwent cholecystectomy and choledocholithotomy with T-tube drainage.Among these 5 cases,one patient with concomitant acute suppurative cholangitis had an emergency surgery,two patients with Ranson score ≤3 had early surgery,and two patients with Ranson score ≥4 had delayed surgery,and all the patients were cured and discharged.Thirty-nine cases with cholecystolithiasis alone were treated with laparoscopic cholecystectomy.Among the 39 patients,25 patients underwent early laparoscopic cholecystectomy,and the other 14 patients underwent delayed surgery,and all the patients were cured and discharged.When compared with delayed group,the average age and Ranson score of early group were lower [(46 ± 12) yrs vs (64 ± 11) yrs and (1.0 ± 0.5) vs (1.5 ± 0.8)],and the median hospital length of stay and the cost were significantly less in the early group than those in the delayed group [(14.0 ± 2.8) d vs (18.1 ± 3.3) d and (17 899 ± 3461) Yuan vs (23 710 ± 3230) Yuan],and the difference between the two groups was statistically significant (P＜0.05).Nevertheless,there was no difference between the operation time and recovery time.There was no conversion to open surgery or post-operative complication in the two groups.Conclusions For severe acute pancreatitis,the delayed operation is recommended when the symptom of pancreatitis is completely improved after conservative management,while for mild acute pancreatitis,early surgery does not increase operation difficulty and complication,and it can decrease the length of hospital stays and costs.

Objective To compare the effect of etomidate and propofol on cardiac and renal function in perioperative elderly patients. Methods 120 perioperative elderly patients were selected and divided into two groups.60 cases in etomidate group (T group) were anesthesia induced by etomidate, and 60 cases in propofol group ( B group) were anesthesia induced by propofol.Hemodynamics, renal function and perioperative indexes were compared after operation.Results Compared with before induction, SBP, DBP and HR were lower after induction(P<0.05), and compared with T group at the same time, SBP, DBP and HR of B group were lower( P<0.05).Compared with before induction, SI, CI and EV were lower after induction (P<0.05), and compared with T group at the same time, SI, CI and EV of the B group were lower(P<0.05).Compared with B group, Cr, BUN and β2-MG of T group were lower ( P<0.05 ) .Conclusion The effects of etomidate on inhibition of cardiovascular system and damage of renal function is slighter, which has important significance for elderly cancer patients.

The article focuses on diagnostic criteria and diagnostic accuracy of the various imaging methods by lymph node metastasis in esophageal carcinoma at present, and compares accuracy of the various imaging methods. In general, the diagnostic accuracy of CT is lower, the diagnostic accuracy of uhrasmall superparamagnetic iron oxide-enhanced MR imaging is higher. Each imaging method has the lower accuracy for the diagnosis of smaller lymph node metastasis. Diagnostic accuracy of endoscopic ultrasonography is higher in the diagnosis of mediastinal lymph node metastasis. Sensitivity of PET/CT is higher for the diagnosis of distant lymph node metastasis.
