BACKGROUND: There is a close correlation between telomere length and cell senescence, immortalization or canceration. OBJECTIVE: To explore the significance of telomere length diversifies in the chronic compartment syndrome in lumbosacral region. DESIGN, TIME AND SETTING: A comparative observation was performed at the State-Level Key Medical Genomics Laboratory, Shanghai Jiao Tong University School of Medicine from July 2007 to February 2008. PARTICIPANTS: The vertical spinal muscular tissue samples were taken from people aged 29-49 years old [mean aged (34.7?12.6) years] including 10 normal people and 15 patients with chronic compartment syndrome. According to the age, the normal were divided into the aged 30-37, and aged 38-45 groups. The abnormal were divided into aged 29-34, aged 35-43 and aged 44-49 groups, with 5 samples in each group. METHODS: DNA was extracted from samples of each group. Telomere length in vertical organizations spinal muscular skeletal muscle was measured by Southen Blotting hybrid technology. MAIN OUTCOME MEASURES: Telomerase length of erector spinal muscles in patients and normal people. RESULTS: The mean telomere length in patients with chronic compartment syndrome was obvious shorter than that of the normal people, which has significant difference (P

Objective To discuss pathogenesis of low back pain induced by chronic compartment syndrome. Method Thirty patients who had definite chronic lumboscaral compartment syndrome without other lumbal diseases were choosed respectively to test muscle force of lumbar and abdomen,intra-sacrospinal muscle pressure,blood routine,ESR,CK,CK-MM,LDH and LDHs.All patients received decompressive operation.Skeletal muscle specimens taken from sacrospinal muscle in each operation were possessed for histological and ultrastructuml observation. Result All of enzyme tests were normal.The author could observe the dissolved degeneration of part of sacrospinal muscle fibers,muscle fiber hypertrophy,and a small quantity of inflammatory cell infiltration with a light microscope.Focal solution of muscle fiber,the aggregation of mitochondria around the nucleus,the increase of lipid droplet and lysosome in cyte,and the proliferation and differentiation of muscle satellite cell could be observed with an electron microscope. Conclusion Pathogenesis of chronic lumboscaral compartment syndrome may be as followed.Intra-compartmental pressures increase,causing metabolism disturbance of the tissues under fascia compartment,damaging skeletal muscle chronically,then inflammatory factors are released,which stimulates posterior branch of spinal nerves,and finally induces low back pain.

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 clarify the actions of tranilast,an anti allergic drug,on chronic constriction mononeuropathy through an experiment using an animal model according to the method of Bennett et al. Methods 36 rats were divided into 2 groups: one was treated with tranilast(200mg/kg?d-1,p.o every experimental day),the other was controlled with solvent only. Chronological changes of heat evoked withdrawal latencies on a hot plate,nerve coducting velocitics, and histopathological changes were compared between the two groups from one to four weeks after loose ligation in the sciatic nerve. Results The changes of the withdrawal latency and nerve conducting velocities in the tranilast treatment group were significantly longer than those in the control. The rats without tranilast treatment showed inflammation in and around the constricted nerve bundles,axonal degeneration,phagocytes invasion and interstitial edematous changes at 7 days,numerous axonal sprouts and remyelination at 14 days,and regeneration in the nerve bundles at 28 days. In contrast,the rats treated with tranilast showed less inflammation or nerve fiber degeneration,and better regeneration than those of the control. Conclusion The actions of tranilast appear to have beneficial effects on prophylaxis of a chronic constriction mononeuropathy and on preservation of the nerve functions in rats.

Objective To study the methods of clinic diagnosis and treatment for chronic lumbar pain induced by lumbo-sacral compartment syndrome. Methods Thirty-three patients with chronic lumbar pain induced by lumbo-sacral compartment syndrome were diagnosed by physical, radiological examination and intra lumbo-sacral muscle compartmental pressure measurement. 33 patients consisted of 15 men and 18 women, with the mean age 42.3 years, and mean duration of chronic lumbar pain was 27 years. Lumbar erector spinae osteo-facial compartment was decompressed using mini-invasive surgery. Lumbar and abdomen muscles were rehabilitated extensively after operation. Results After operation, symptoms of low back pain were alleviated significantly, and walking distance were promoted as well. Post operative flexion and extension of lumbar spine were increased to (15??0.5?) and (7??0.7?) respectively. Intramuscular pressure in rest state, during movement and no more than 6 min after movement was (6.8?0.8), (162.3?12.35) and (7.1?0.6) mm Hg respectively [before operation was(10.4?0.9), (187.1?11.16) and (13.2?1.3) mm Hg respectively, P

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.

Objective To investigate the effects of 2 450 MHz microwave irradiation on the proliferation of cultured mouse fibroblasts in vitro, and the related gene and protein expressions. Methods Cells from mouse skin were directly radiated with microwaves of different intensities for different periods. The proliferation of fibroblasts was assayed by the MTT method, and the effects of microwave radiation on the fibroblast cell cycle were measured by flow eytometry. The mRNA expression of types Ⅰ and Ⅲ procollagen was detected by real-time RT-PCR. Anti-phosphoryl- ation extracellular-regulated kinase (ERK-1/2) antibody was introduced in immunofluorescence staining analysis to observe any changes in the phosphorylation of fibroblast protein ERK. Results ① 5 W/cm2 or 1.0 W/cm2 irradia- tion for 5 min, 15 min, or 30 min did not significantly decrease fibroblast proliferation, but irradiation at 5 W/cm2 for more than 5min caused a significant decrease in fibroblast proliferation. ②After 5 W/cm2 irradiation for 5 min, the percentage of cells in the G0/G1phase was significantly increased, and ERK was activated immediately after irradia- tion. ③The mRNA expression of type Ⅰ procollagen was down-regulated after microwave irradiation, and the magni- tude of the decreased expression correlated positively with the duration of irradiation. Thirty minutes of microwave ir- radiation at 1 W/cm2 or 5 minutes at 5 W/cm2 significantly down-regulated the mRNA expression of type Ⅰ procolla- gen and the ratio of types Ⅰ and Ⅲ. Conclusion High-intensity microwaves may inhibit the proliferation of fibro-blasts in a dose-dependent manner in vitro and down-regulate procollagen mRNA expression, which might be achieved by activating mitogen-activated protein kinase signal transduction gateways.
