Chinese Journal of Physical Medicine and Rehabilitation.2010;32(10):777-780. doi:10.3760/cma.j.issn.0254-1424.2010.10.016

Objective To compare the effect of treating chronic colonitis diarrhea (CCD) using He-Ne laser irradiation of acupoints with routine drug treatment. Methods Two hundred patients with CCD were randomly divided into a laser irradiation group (laser group) and a routine drug treatment group (control group) with 100 patients in each group. The laser group patients were treated with a He-Ne laser ( power density 478 mW/cm2 )through coupling fiberoptic cable radiating onto the Shenque (REN8) , bilateral Tianshu (ST25) and Dachangshu (BL25) acupoints, each for 10 min daily for 10 days. Control group patients were treated with routine drugs such as antibiotics, astringents, antidiarrheals, antispasmodic analgesics, vitamins and Chinese herbal enemas. Three months after treatment the patients were examined by fibercoloscope to evaluate the therapeutic efficacy in the two groups. Results In the laser group 66 cases (66%) experienced a short-term cure, 27 cases (27%) improved and7 cases (7%) showed no effect. In the control group 33 cases (33%) were short-term cures, 43 cases (43%) improved and 24 cases (24%) had no effect. These differences were statistically significant. In both groups the effects for patients with short histories was better than for those with longer histories. In the laser group the pathological changes in the distal colon were significantly better than in the proximal colon, but this difference wasn't significant in the control group. The average days of total treatment to achieve short-term cure and improvement in the laser group were significantly less than in the control group. In the laser group the average days to the disappearance of abdominal pain and diarrhea in the short-term cure patients of was significantly fewer than in the control group. Conclusions Laser irradiation was more effective than routine drug treatment, especially for stopping diarrhea, spasmolysis and analgia.

Chinese Journal of Physical Medicine and Rehabilitation.2010;32(10):740-743. doi:10.3760/cma.j.issn.0254-1424.2010.10.006

Objective To investigate the effect of cold atmospheric plasma (CAP) on the healing of skin ulcers using Balb/c mice. Methods Wounds with a diameter 6 mm were created on each side of the backs of BalB/c mice ( n = 150) using a punch bioptome. The mice were assigned randomly into a control group ( wounds healed naturally), a laser group (wounds treated with a He-Ne laser for 10 min daily) and a CAP group (wounds treated with CAP for 10 min daily). Wound healing was evaluated on postoperative days (PODs) 4, 7, 10 and 14 in terms of percent wound closure. Ten mice per group were sacrificed on each of the evaluation days. Both wounds were removed and a histological examination was conducted. A scoring system was used to evaluate the wounds. The expression of vascular endothelial growth factors (VEGFs) in the wounded tissue was detected by using immunohistochemical methods on POD 7. The results were quantified using an HPIAS-1000 system. Results Compared with the control group, the average percentage of wound healing was significantly greater in the CAP group on PODs 7 and 10. The average scores on the histological examination were significantly higher in the CAP group on PODs 7, 10 and 14. Compared with the other two groups, the expression of VEGF was up-regulated significantly in the CAP group.Conclusions CAP can positively affect the wound healing process. This might be related to the up-regulation of VEGF in the wounded tissues.

Chinese Journal of Physical Medicine and Rehabilitation.2010;32(10):735-739. doi:10.3760/cma.j.issn.0254-1424.2010.10.004

Objective To study the effect of magnetic stimulation on the expression of B cell lymphoma/leukemia gene 2 ( Bcl-2 ) and caspase-3 genes, and the apoptosis of neurons in rats with spinal cord injury (SCI).Methods Sixty rats were randomly divided into a magnetic stimulation group, a model group and a sham-operation group. An SCI model was established in the magnetic stimulation and model groups. The magnetic stimulation was applied at the 6th, 12th, 24th and 72nd hour after the operation to the rats in the magnetic stimulation group, and sham magnetic stimulation was given to the model group and sham-operation group rats at the same time points. Two hours after treatment, 5 rats of each group were sacrificed and their injured spinal cords were sectioned. The gene expressions were detected using immunohistochemical techniques, and apoptosis of neurons was observed by the TUNEL method. Results Few apoptotic cells were found in the sham-operation group, but more were found in the model group. Apoptotic cells in the magnetic stimulation group were significantly fewer than in the model group. The expression of both Bcl-2 and caspase-3 in the magnetic stimulation and model groups was significantly higher than in the sham-operation group at the different time points. Expression of Bcl-2 in the magnetic stimulation group was significantly higher than in the model group, but expression of caspase-3 in the magnetic stimulation group was significantly lower than in the model group. Conclusions Magnetic stimulation up-regulates the expression of Bcl-2 genes and down-regulates the expression of caspase-3 in injured neurons. Magnetic stimulation might have protective and rehabilitative effects after human SCI.

Chinese Journal of Physical Medicine and Rehabilitation.2010;32(10):730-734. doi:10.3760/cma.j.issn.0254-1424.2010.10.003

Objectiye To study the mechanism by which transcranial magnetic stimulation (rTMS) affects cognitive dysfunction in vascular dementia (VD). Methods Thirty-six male Wistar rats were randomly divided into a control group, a VD group, a low frequency rTMS group and a high frequency rTMS group. Two-vessel occlusion was employed to induce VD models. Low frequency rTMS group rats were given 0.5 Hz rTMS for six weeks. High frequency rTMS group rats were given 5 Hz rTMS for six weeks. Morris' water maze test was used to measure their spatial learning ability and memory. The ultrastructures of the synapses in the four groups were detected with transmission electron microscopy. The expression of synaptophysin (SYN), brain derived neurotrophic factor (BDNF) and Nmethyl-D-aspartate receptor 1 ( NMDAR1 ) mRNA and protein in the hippocampus were determined by real-time PCR and Western blotting. Results The behavior and morphology of the rats treated with rTMS improved. The average expression of SYN, BDNF and NMDAR1 mRNA and protein in the low frequency rTMS group and the high frequency rTMS group were significantly higher than in the VD group. Conclusion rTMS can provide a rehabilitative effect for VD. The mechanism might be associated with enhancing the expression of SYN, BDNF and NMDAR1 in the hippocampus.

Chinese Journal of Physical Medicine and Rehabilitation.2010;32(10):721-724. doi:10.3760/cma.j.issn.0254-1424.2010.10.001

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 observe the influence of exercise intensity on cardiorespiratory function in the elderly with coronary heart disease using simplified 24-action Taijiquan and jogging. Methods A total of 115 sedentary elderly patients with heart disease were randomly divided into a control group ( no exercise), a low-intensity exercise group, a medium-intensity exercise group (whose exercise was simplified 24-action Taijiquan at 40-60% of their individual maximum oxygen consumption (VO2max) for 90 to 200 minutes per week) and a high-intensity exercise group ( whose exercise was jogging on a treadmill at ＞ 70% of their maximum oxygen consumption for 200 minutes per week). The regime was maintained for 6 months. All patients accepted a treadmill exercise test before and after the 6 months of exercise to evaluate the changes in VO2max, maximum heart rate ( HRmax), VO2max/HRmax and exercise time (t). Results ( 1 ) After 6 months of exercise, VO2max, HRmax, VO2/HRmax and t had increased sisnificantly in all three exercise groups. Work capacity had increased 18.6% , 33% and 34.4% and HRmax had increased 9.3% , 13.8%, 19.1%. There was no difference between before and after in the control group. (2) Compared with the control group the average VO2max, HRmax and t of all three exercise groups had increased significantly. VO2 max was 9.4% , 26% and 23. 1% better; HRmax was 6.7% , 8.8% and 12% better; t was 3.5,4 and 4.9 minutes longer. (3) Compared with the low-intensity exercise group, VO2max, HRmax and t in the medium- and high-intensity groups increased significantly more. VO2max increased 16.6% and 13.7% more; HRmax increased 2.1% and 3.2% more and average t was 0.5 and 1.4 minutes longer. (4) There was no significant difference between the medium- and high-intensity exercise groups in terms of VO2max. (5) The incidence of self-reported adverse responses to exercise such as dizziness, chest stuffiness and fatigue in the high-intensity exercise group increased significantly compared with the other 3 groups. Conclusions Exercise can gradually improve cardiorespiratory function in the sedentary elderly with heart disease. The effects of medium-intensity exercise are similar to those of high-intensity exercise, but medium intensity is safer.

Objective To study the kinematic characteristics of normal subjects and hemiplegic patients in activities of daily living (ADL) by three-dimensional (3D) kinematic analysis. Methods A Vicon motion capture system was used to record 3D kinematic data on 15 normal subjects ( the healthy group) and 10 hemiparetic patients (the hemiplegic group) performing 5 ADL tasks: reaching up, combing, drinking, touching the opposite shoulder and touching the back pocket. The movement times and the 3D motion angles of the sternoclavicular joint,the acromioclavicular joint, the shoulder joint, the elbow joint and the wrist joint were recorded. Three-dimensional joint angles and movement times were compared between the normal group and the hemiplegic group. Results Compared with the normal group, the hemiplegic group had significantly more lateral rotation and abduction of the sternoclavicular joint, medial rotation and extension of the acromioclavicular joint and flexion of the elbow joint.The hemiplegics used significantly less medial rotation of the sternoclavicular joint and adduction/abduction, flexion/extension and lateraL/medial rotation of the shoulder joint. Additionally, the hemiplegic group showed significantly longer movement times. Conclusion Hemiplegics use different joint motor patterns from healthy subjects in completing ADL actions.

Chinese Journal of Physical Medicine and Rehabilitation.2010;32(11):816-820. doi:10.3760/cma.j.issn.0254-1424.2010.11.004

Objective To investigate the expression of JAM-1 after microwave irradiation and its correlation with blood-brain barrier integrity. Methods A total of 160 male Wistar rats were divided into a sham radiation group and a radiation group. The radiation group was subdivided into three sub-groups treated with micrewaves at average power densities of 10, 30 and 100 mW/cm2. Rats in each group were sacrificed and their brain tissue sampled at 6 hours and 1, 3, 7 and 14 days after the irradiation. Evans blue ( EB ) dye, laser confocal microscopy,Western blotting, RT-PCR and image analysis were used to test the permeability of the blood-brain barrier and the expression of JAM-1 in protein and at the gene level in the rats' hippocampus and cortex. Results There was an increase of EB in the hippocampus 3 to 14 days after 10 and 100 mW/cm2 microwave irradiation. The EB level increased progressively in the 10 and 30 mW/cm2 groups within 7 d after irradiation but recovered by the 14th day. It also increased progressively in the 100 mW/cm2 group within 14 d after irradiation. In the hippocampus, EB was observed only in the lumens of the blood vessels in the sham group, but EB had diffused out of the blood vessels in the irradiated groups by the 3rd day after irradiation. After 10 or 30 mW/cm2 microwave irradiation, JAM-1 protein in the hippocampus and cortex decreased significantly within 7 d after irradiation but recovered by the 14th day. It decreased progressively in the 100 mW/cm2 group within 14 d after irradiation. The expression of JAM-1 mRNA in the hippocampus decreased significantly at 6 h after irradiation at all power levels, but it recovered within 7 days in the 10 and 30 mW/cm2 groups. Conclusions Microwave radiation can decrease the expression of JAM-1 in the hippocampus and cortex. The degree of decrease is positively correlated with the microwave radiation power. The change might involve increasing the permeability of the blood-brain barrier.

Chinese Journal of Physical Medicine and Rehabilitation.2010;32(11):801-804. doi:10.3760/cma.j.issn.0254-1424.2010.11.001

Objective To investigate the effects of pulsed electromagnetic fields (PEMFs) of different intensities on bone metabolism in ovariectomized rata. Methods Sixty 10-month-old female Sprague-Dawley rats were randomly divided into a normal group, an ovariectomized control group, a 0. 14 mT group, a 0. 16 mT group, a 0.18 mT group and an estrogen group. All rats except those in the normal group were subjected to bilateral ovariectomy. Beginning one week after the operation, the rats in the 0. 14 mT, 0. 16 mT and 0.18 mT groups were treated with PEMFs at 50 Hz, 60 min daily for 90 days, while those in the estrogen group received estrogen instead. During the experiment, the bone mineral density (BMD) of the whole body was observed dynamically, and local BMDs and biochemical indexes were measured after 3 months of treatment. Results Alkaline phosphatase (ALP) activity in the normal group was significantly lower than in the other groups. Tartrate-resistant acidic phosphatase 5b (TRAP5b)activity was elevated significantly, in the control and 0.14 mT groups compared with the normal group. After 2 months of treatment, whole body BMD was reduced significantly in the 0.14 mT group compared to the normal group. After 3 months of treatment, whole body BMD in the ovariectomized controls and the 0.14 mT group was reduced significantly compared to the normal group, but significantly elevated in the 0. 16 mT, 0.18 mT and estrogen groups when compared to the ovariectomized control group. At the end of 3 months of treatment, the trends in lumbar vertebral BMD were similar to those of the whole body BMD, with the femoral BMD in the ovariectomized group and the 0.14 mT group significantly lower than in the normal group, though the differences among the other groups were not statistically significant. Conclusions PEMF treatment at 50 Hz and 0.16 mT or 0.18 mT can promote bone formation. PEMFs at 50 Hz and 0.14 mT might stimulate bone resorption. An intensity-window effect exists in the action of PEMFs on bone metabolism in ovariectomized rats.

Objective To establish an early cognitive disorder model in rats and investigate the early cognitive functioning after ischemic hypoxic brain injury during the neonatal period. Methods Forty-six newborn Sprague-Dawley rats were randomized into a 21-d-old group and a 31-d-old group. These 2 groups were then subdivided into model and sham-operated subgroups (M21, n=12; SH21, n=11; M31, n=12; SH31, n=11). A model of neonatal early cognitive disorder was established in the rats of the M21 and M31 groups using a modification of Rice's method. Rats in the SH21 and SH31 groups received skin incisions and common carotid artery separation without ligation or hypoxia. Each group was tested with a Morris water maze. The rats were sacrificed after testing, and brain tissue was examined under the electron microscope. Nissl staining allowed Nissl body quantification and neurocyte acin the M21 group was significantly longer than in the SH21 group. The 31-d-old subgroups had shorter average escaping latencies than the corresponding 21-d-old subgroups. (b) Spatial memory: The average platform times, Ⅰ region times and Ⅰ region distances showed no significant differences among groups. ②Brain pathology (a) Gross appearance: Obvious ischemic hemisphere atrophy was observed in the M group, and no abnormality was observed in the SH group. (b) Electron microscopic observation: In the SH group cell ultrastructures in the ischemic hippocampus were normal. Karyopyknosis and dilated endoplasmic reticulums were found in the M group. More mitochondria were found in the presynaptic membranes of the ischemic hippocampus in the M group than that in the SH group. (c) Nissl body quantification and neurocyte activity analysis: Significantly less activity in the ischemic cortex was found in the M21 group compared to the SH21 group. More activity was observed in the 31-d-old subgroups than in the corresponding 21-d-old subgroups. Conclusions ①The neonatal rats with ischemic hypoxic brain injury had prolonged average escaping latency and depressed neuronal activity. ②The 31-d-old rats had better spatial localization learning ability than the 21-d-old rats.
