Objective To discuss the video-urodynamic characteristics and management in infra-sacral cord injured patients. Methods The video-urodynamic finding and managements in 169 patients was reviewed. They were followed up for 2 years. Results Detrusor areflexia was found in 76.33% (129/169) patients, among them there were 27.22% (46/169) patients appeared hyper-compliance, and 7.10% (12/169) patients appeared reflux. The video-urodynamic characteristics showed over activity and low-compliance in 12.43% (21/169) patients, including reflux in 5 cases. Different management was chosen according to the video-urodynamic examination. No special complication was observed after 2 years follow-up. Conclusion The majority patients with infra-sacral cord injury appeared detrusor areflexia and hyper-compliance. Special management according to the video-urodynamic characteristics is important for protecting upper urinary tract and preventing urinary system infection.

Objective To explore a simple and effective way of establishing a mice orthotopic tracheal transplantation model in studying bronchiolitis obliterans to reduce operation time. Methods Tracheas from C57BL/6 mice (n=30) were im?planted into Balb/c mice (n=30). Grafts and hosts were matched according to body weight.Orotracheal intubation and endo-stentwas used for trachea anastomose and animal model was establish. Operating time was also noted. Grafts were harvest?ed on Days 15, 30 and 60 after transplantation, using HE staining to observe pathological changes of allograft. Trachea block?ing rate was also calculated. Results Until survival of trachea transplantation, the operative time of donor′s and the recipi?ent′tracheas resection were (7.0±1.0) min and (7.0±1.0) min respectively.Orotracheal intubation the endo-stentestablish?ment cost(1 ± 0.5)min. Trachea anastomose took(20.0 ± 4.0)min and the operation time last(43.0 ± 10.0)min. Conclusion The improvement of orthotopic tracheas transplantation usingOrotracheal intubation the endo-stenfor trachea anastomose is esay-operated and did required complicate skills and instruments with high successful rate. So it is an ideal and stable model in studying bronchiolitis obliterans.

Objective To evaluate the diagnostic and differentiable value of video-electroencephalogram(VEEG)in sleeping-related seizure disorder.Method Sixty-five cases with sleeping-related seizure disorders(35 suspected epilepsy and 30 suspected non-epileptic seizure)enrolled in our clinics from Jan.2005 to Jun.2006 were examined by VEEG and EEG.Results Among 35 children suspected to have the possibility of epilepsy,the epileptic discharge rate examined with VEEG was 62.86%(22/35),which were significantly higher than that by EEG was 17.14%(6/35)(P

OBJECTIVE: To study the objectivity and reliability of needle electromyography and nerve conduction for detection of musculus extensor digitorum brevis strength, which may provide a basis for establishing a quantitative detection of muscle strength in forensic clinical study. METHODS: Forty-four healthy people were enrolled as the subjects, and during toe dorsiflexion, the following items including needle electromyography indexes, motor unit potential (MUP) amplitude, MUP count, recruitment reaction type, and nerve conduction detection indexes, compound muscle action potential (CMAP) amplitude, CMAP latent period and motor nerve conduction velocity (MNCV), were simultaneously detected under the cooperation and disguise condition. RESULTS: Under the cooperation condition, regardless of the same operator or different operators, there were good test-retest reliabilities in MUP amplitude, CMAP amplitude, CMAP latent period and MNCV, while there were normal test-retest reliabilities in MUP count and recruitment reaction type and the repeatability of the same operator was slightly better than the repeatability between different operators. Under the disguise condition, test-retest reliabilities of MUP amplitude, CMAP amplitude, CMAP latent period and MNCV were relatively high, while test-retest reliabilities of MUP count and recruitment reaction type were relatively low. CONCLUSION There are good test-retest reliabilities in MUP amplitude, CMAP amplitude, CMAP latent period and MNCV, which can be conducive to comparison between different operators and results at various times; MUP count and recruitment reaction type, which can be easily affected by subjectivity of operators and examinees, can be used to differentiate whether an examinee disguises or not. The indexes used to objectively judge muscle strength remain to be further investigated.

Objective To explore the levels of neuron-specific enolase(NSE) and tumor necrosis factor-?(TNF-?)concentrations of serum and cerebrospinal fluid(CSF) in children with epilepsy,and evaluate its relationships with neuronal damage.Methods Sixty-two epilepsy children were divided into 2 groups:severe group including 28 cases of frenquent seizures ≥3 vices or time of master single test seizures≥15 min,mild group including 34 cases of infrenquent seizures

ObjectiveTo observe the effect of progesterone on progesterone receptor in brain tissue with hypoxia-ischemia brain da-mage(HIBD) in neonatal rats,and discuss the protective mechanism of progesterone on HIBD of neonatal rats.MethodsTwenty-four 7-day-old neonatal rats were randomly divided into 3 groups:sham-operated group,hypoxia-ischemia group and pretreatment group.Rats in hypoxia-ischemia group and pretreatment group were subjected to left common carotid artery ligation,then were exposed to 80 mL/L oxygen and 920 mL/L nitrogen gas in 37 ℃ closed container for up to 2.5 h to establish hypoxia-ischemia encephalopathy(HIE) model.Progestero-ne was injected intraperitoneally into pretreatment group rats respectively at 30 minutes before hypoxia,solution was injected into the first 2 groups.All rats were killed at the 24 hour after operation,immunohistochemistry staining was used to examine the expression of progesterone receptor in brain.ResultsTotally 24 neonatal rats entered the result analysis without loss.Progesterone receptor was expressed in both endochylema and nucleus in every group rat.The amount of the positive cell of progesterone receptor in hypoxia-ischemia group significantly decreased compared with that in sham-operated group(P

Objective To find methods to isolate and purify plasminogen activator (Pla) from artificial culture of Yersinia pestis. Methods Ultrasonication and urea extracting combined by ammonium sulfate salting-out were tried to extract Pla. High performance liquid chromatography(HPLC) was used to purify Pla. The first step was ion exchange and the second was gel filtration, Preparative electrophoresis was used to purify Pla, too. The enzyme activity of the isolated or purificated Pla was detected. Results Both 50% - 60% saturated ammonium sulfate deposition of supernatant of plague bacilli ultrasonication and 0 - 10% saturated ammonium sulfate deposition of supernatant of plague bacilli powder soaked by urea had three bands(Mr about 31×103, 35×103 and 37×103) and lysis rings were 6.5 and 7.2 mm in diameter respectively when the enzyme activity was detected. Pla purified by HPLC was mainly composed of three bands(Mr about 31×103, 35×103 and 37×103), occupying more than 80% of total protein weight and lysis ring was 5.0 mm in diameter. Pla purified by preparative electrophoresis mainly consisted of three bands(Mr about 31×103, 35×103 and 37×103) with other proteins of low concentration nearby, no lysis ring was detected. Conclusions Pla is collected by the methods of ultrasonication and urea extracting. Priliminary purification of Pla can be achieved by HPLC and preparative electrophoresis.
