Purpose: Three kinds of embolizing agents, sodium mirrhuate, lipiodol and gelfoam were used together in treating hemangiomas of liver, pharynx, and spleen by embolizing the arteries. Materials and methods: 35 patients with hemangiomas, 30 cases in liver, 1 in spleen, and 4 in pharynx, were treated with embolizing hepatic artery, splenic artery, maxillary arterry, and face artery, respectively. Results: Tumors decreased 20%～90% in size, and none of then had continued to grow after the treatment for 3～36 months. At the same time, the suitable dose of embolizing agent according to the size of the tumor, the injection speed, the observation of the curative effect and the precaution of the embolization were also discussed, It showed that the effect of this method was better than using only one or two kinds of embolizing agents togethes resued in only slight complications. Conclusion: We think this method is safe and effective by combined with embolizing agents in treating hemaiomas of different organs and tissues.

BACKGROUND:Gait analysis enable to convert qualitative analysis and description used for a long time in orthopedic examination and rehabilitative treatment into objective and precise quantitative assessment. At the present, with the development of science and technology, three-dimensional (3D) gait analysis is more and more widely, extensively used in orthopedic surgery and rehabilitation medicine abroad, while much less in China.OBJECTIVE: To study the parameters of time-distance, kinematics, kinetic and electromyography (EMG) in healthy subjects and patients with backbone, hip, knee or ankle joint diseases.DESIGN: Comparative observation and control study.PARTICIPANTS: From December 2004 to July 2005, 40 healthy subjects and 112 patients suffering from backbone and hip, knee, ankle joint disease were selected from the Department of Rehabilitative Medicine, Sixth People's Hospital Affiliated to Shanghai Jiao Tong University and analyzed by three dimensional gait analysis system (VICON 612 system made by Britain VICON Company). 112 patients including 42 males with the mean age of (46.2 ± 2.3) years and 70 females with the mean age (41.2 ± 3.5) years were screened by skilled clinicians after surgical and rehabilitative treatment.Among them there were 21 patients with cervical vertebra, 26 patients with prolapse of lumbar intervertebral disc and lumbar spinal stenosis. The number of hip, knee, ankle joint disease was 12, 34, 19 respectively. Total hip replacement was included in hip joint disease, anterior cruciate ligament (ACL) reconstruction was included in knee joint disease, talipes equinovarus was included in ankle joint disease. Meanwhile, 40 healthy subjects who were 20-40 years old, male or female, without any clinical symptom of backbone and limbs volunteered in the study.METHODS :Gait analysis were carried out on 40 healthy volunteers and 112 operational and rehabilitative treatment patients with spinal and lower limb diseases using VICON 612 system made by Britain VICON Company.MAIN OUTCOME MEASURES: The time-distance parameters (cadence, step length, walking speed), kinematics parameters (knee flexion/extension degree, hip flexion/extension degree, ankle dorsi/plantar degree), kinetic parameters (knee force in Z axis, hip force in Z axis, normalized force in Z axis) and EMG parameters (vastus lateralis SEMG) of lower limbs were examined.RESULTS: A total of 40 healthy subjects and 112 patients were involved in the analysis of results. ① Time-distance parameter: Cadence, as well as step length and walking speed of patients with backbone disease, patients with hip joint disease, patients with knee joint disease, and patients with ankle joint disease were lower than those of healthy subjects,and the difference between two groups was significant (P ＜ 0.05-0.01). ② Kinematic and kinetic parameters of all joints in upper limbs: One year after left ACL knee reconstruction, the extension of left knee in initial contact phase was 9° less than that of right one and the stress in Z axis of left knee was much less than that of right one; One year after left THA,the flexion of left hip in initial contact phase was 8.5° less than that of right one, the extension of left hip in terminal stance phase was 3° less than that of right one, during stance phase the stress in Z axis of left hip was much less than that of right one; As to an infantile paralysis patient with talipes equinovarus, the dorsiflexion of left ankle in initial contact phase was 12° less than that of right one, the plantar flexion of left ankle in terminal stance phase was 5° less than that of right one. The stress in Z axis of left ankle during stance phase was much less than that of right one. However, the difference in range of motion and stress in Z axis was not significant between the left and right knee joint in healthy people. ③ One year after left total knee arthroplasty, the dynamic surface electromyogram signals of left vastus lateralis is much lower than that of right vastus lateralis in a gait cycle.CONCLUSION: 3D gait analysis enables tprovide objective basis for making operation scheme for orthopedic surgery and after-operation rehabilitation therapy, and assessing curative effect of rehabilitation therapy.

BACKGROUND:Evaluation plan for the neuro-musculo-skeletal system model and motor function was little.However,the three-dimensional gait analysis can transfer qualitative analysis and object description which widely used in orthopedics and rehabilitation medicine to quantitative evaluation with more objective and precise.OBJECTIVE:To evaluate gait kinematics and kinetic changes after total knee replacement based on 12 months follow up using three-dimensional gait analysis.DESIGN,TIME AND SETTING:The comparative observation and case-control study was performed in the Gait Analysis Room of the Department of Rehabilitation Medicine in the Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University from January 2007 to May 2008.PARTICIPANTS:Ten patients with knee osteoarthritis following total knee replacement were chosen as treatment group;concurrently,ten patients whose baseline data were matched with the treatment group without problems in nerve,muscle,skeletal system and equilibrium were selected as the control group.METHODS:Ten patients in the treatment group underwent rehabilitation training,then compared time-distance,kinematic,and mechanical parameters which were measured at 3,6,12 months after total knee replacement with the control group.MAIN OUTCOME MEASURES:Time-distance parameter,kinematic parameter,mechanical parameter and knee functional scores.RESULTS:Pace,step frequency,gait speed,and time of injured leg standing were notably decreased,while time of uninjured leg standing,duration of gait cycle were obvious prolonged compared with the control group(P

Objective To analyze the clinical characteristics and therapy of levofloxacin-induced prolonged Q-T interval in patients with multi-drug resistant tuberculosis ( MDR-TB) . Methods Clinical materials of 6 patients with MDR-TB who developed prolonged Q-T/QTc interval caused by levofloxacin therapy were analyzed. Those cases were collected from the Tuberculosis Prevention and Control of Wuhan City form April 2010 to August 2014. Results The proportion of patients with levofloxacin-induced prolonged Q-T interval was approximately 3.0%.The condition occurred 2-8 months after the administration. The initial value of QTc interval ranged from 397 ms to 439 ms, while the average was (410.17±14.62) ms.The value of QTc interval was extended to 470-486 ms after treatment of levofloxacin, while the average was (476.33±6.16) ms.The increase of QTc interval was 47-85 ms, while the average was ( 66 ± 11. 48 ) ms. None of them developed Tdp. Conclusion The application of high dosage and long treatment course of levofloxacin in patients with MDR-TB could result in the extension of the Q-T/QTc interval, which should arouse our serious attention. In order to detect the abnormal Q-T/QTc interval in early stage, electrolyte level examination as well as ECG examination should be considered as routine tests before initiation of treatment and during the follow-up treatment.

The study of neuronal activity with low frequency has shown an increasing interest for its greater stability and reliability recent years. One challenge in analyzing this kind of activity is to find similarities and differences between signals efficiently and effectively. The traditional analysis methods, such as short-time Fourier transform, are easily obscured by background noises and often involve a large number of parameters. Therefore, this paper introduces a novel time-frequency analysis method based on wavelet transformation and half-ellipsoid modeling to extract instantaneous frequency and instantaneous phase information. This method overcomes some shortcomings of conventional time-frequency analysis. In this method, wavelet transformation is used to provide high-level representations of raw signals, and parsimonious half-ellipsoid models are used to extract changes in time domain and frequency domain of neural recordings. The method was validated to local field potentials (LFPs) of olfactory bulb of anesthetized rats during three different odor stimuli. The results suggested that this method could detect odor-relevant features from olfactory signals with large variability. The Odors then were classified with support vector machine (SVM) algorithm and the classification accuracy reached 79.4%.
