Chinese Journal of Rehabilitation Theory and Practice 2016;22(1):8-12
Objective To observe the effect of wheel running exercise on subventricular zone neurogenesis and the neural function in rats post cerebral ischemia. Methods 48 adult male Sprague-Dawley rats were induced cortical infarcts with left middle artery occlusion and were housed in either standard (control group, n=24) or wheel running (exercise group, n=24). They were assessed with neurological severi-ty scores (NSS), and the expression of Ki67 was determined with immunofluorescence, 3, 7, 14 and 21 days after training. Results Com-pared with the control group, the number of Ki67-labeled cells in subventricular significantly increased in the exercise group 14 and 21 days after ischemia (P<0.05), and the NSS decreased since 7 days after ischemia (P<0.05). Conclusion Wheel running may promote the neuro-genesis in subventricular of adult rats after cerebral infarction, which may associate with the recovery of neural function.

Objective To compare the effects of semi conductor laser nasal cavity irradiation with He Ne laser intravenous irradiation therapy on patients with brain lesion. Methods Ninety six cases of cerebral infarction(CI), traumatic brain injury(TBI) were randomly divided into semi conductor laser group (group A, n =50, ?=650nm , 2.4mW, 30mins/nasal cavity), He Ne laser group (group B, n =46, ?=632.8nm, 2.5mW, 40mins/ intermedia cubiti vein or basilic vein). The changes of the blood lipids, hemorheology parameters, scores with Fugl Meyer movement scale and Barthel index assessment were compared after the semi conductor laser and He Ne laser irradiation. Results After laser irradiation,The CHOL, TG, LDL, ESR and HCT were significantly reduced in both groups( P 0.05). The brain damage area was reduced in all the patients as revealed by CT examination. Conclusion The influence of the two kinds of laser irradiation therapies is similar when applied in patients with brain injury. But semi conductor laser nasal cavity irradiation is a simple, safe, inexpensive therapy for the patients.

Objective To study the effects of rehabilitative training on motor function and expression of GAP-43 and SYN in rats with local cerebral infarction. Methods A total of 76 male adult Sprague-Dawley rats were randomly divided into a rehabilitative training group(n=32),a control group(n=32),and a sham-operated group(n=1 2).All the rats were subjected to left middle cerebral artery occlusion(MCAO)with the suture occlu sion.Motor training programs including balancing,grasping,rotating and walking exercises were administered to the rats of the rehabilitative training group at 48 hours post-operation,while those of other two groups were reared in their original living status without any special training.The animals were given behavioral tests with Bederson test,balancing wood test,net screen test to assess the functional outcome,and immunohistochemistry staining was employed to evaluate the exDression of GAP-43 and SYN in peri-infarction cortex at the 3rd,7th,21 st,35th days after MACO,respectively. Results The scores of behavioral tests in the rehabilitative training group was better than those in the control group(P<0.05)at the 7th,21 st,35th day after MCAO,and the immunostaining showed that expression of GAP-43 was higher in the rehabilitative training group than that in the control group(P<0.05)and the sham operated group(P<0.01)at the 7th and 21 st days post-operation,respectively,and that the expression of SYN was higher in the rehabilitative training group than that in the control(P<0.05)and the sham operated groups(P<0.05)at the 21 st and the 35th days post-operation,respectively. Conclusion Rehabilitative training can improve func tional recovery in rats with local cerebral infarction,and the function enhancement may be partially attributed to the up-regulation of expression of GAP-43 and SYN in peri-infarction cortex.

Objective To study the effects of rehabilitation training on angiogenesis and its ultrastructure and expression of CD32 in the peri-infarction region of rats with focal cerebral infarction. Methods Sixty-six Spra-gue-Dawley rats with experimental left middle cerebral artery occlusion (MCAO) were used as subjects in this study. All the rats were randomly divided into three groups: a rehabilitation training group (n=30), which was given bar rotating, balancing and rolling exercises everyday after 48 hours post MCAO; a control group (n = 30) and a sham-operated group (n=6), which were fed in cages with no special training exercises. Then brain tissues were fixed on the 3rd d, 7th d, 14th d after MCAO, for observing the morphological alterations of microvessels in peri-infarction re-gion using transmission electron microscope, immunohistochemistry and Western blotting were used to measure the ex-pression of CD31, which acted as the marker of the neogenetic microvessels. Results (1) It showed that the capil-lary endothelial cells were less edematous in the rehabilitation training group, and there were less pinocytosis bullae in basal membrane more integral nucleus of endothelial cells in rehabilitation training group when compared with those in the control group. (2) Expression of CD31 can be observed in peri-infarction region in both groups from the 3rd d on-wards, and peaked on the 7th d, and then gradually went down after the 14th d. Comparison between the 2 groups showed that the expression of CD31 in rehabilitation training group was higher than that in the control group at every time point, but statistical difference between the 2 groups in this regard could be revealed only on the 7th d (P< 0.05), Conclusion Rehabilitation training could promote ultrastruetural recovery of microvessels and induce an-giogenesis in peri-infaretion region, and it might be one of the mechanisms of neural functional recovery in rats after MCAO.

Objective To test the reliability and validity of the brief International Classification of Functioning, Disability and Health (ICF) core sets for Chinese stroke patients using Rasch model analysis. Methods The body functions of 38 Chinese stroke patients were measured using the brief ICF core sets. The qualifiers of the 20items were measured by two raters and analyzed using FACETS statistical software. The intra-rater reliability and validity were tested by using the separation index and separation reliability and fit analysis. Results The brief ICF core sets had good internal consistency and reliability (person separation index = 6.02, person separation reliability = 0.94 ) with these Chinese patients. The raters showed significantly different strictness in rating, but their ratings had good internal self-consistency. The construct validity was good for the body functions of the ICF component ( separation index = 10.50, separation reliability = 0.80) , but misfitting and overfitting were found in items b117, b152and b755. Conclusion The body function of the brief ICF core sets has good reliability and validity for Chinese stroke patients. A many-facet Rasch measurement model can provide comprehensive information and has good application prospects for testing the reliability and validity of ICF core sets.

Objective To investigate activation patterns in the motor cortex of patients with cerebral infarction by blood oxygen level dependent-functional magnetic resonance imaging ( BOLD-fMRI) , and to explore the brain's functional reorganization mechanism. Methods Sixteen patients ( 12 men and 4 women, age 37 to 80, mean 61.0±11.3) who had suffered a subcortical infarction within the previous 3 months were studied. All the patients received fMRI scanning during passive flexion-extension movement of both the affected and unaffected wrist separately.Brain functional mapping was acquired with SPM2 software. Activation patterns in the brain were compared between the affected and unaffected hands. Results The volume and intensity of the activated areas were diverse, but showed some order. When the affected hand moved, the fMRI map showed general hyperactivation. When the unaffected hand moved, the contralateral M1 and S1 were activated. Conclusions After cerebral infarction, the brain cortex showed compensatory changes. As the main motor cortex (M1) was deactivated, the subsidiary motor areas such as the PMC, SMA, CMA, IPL, PFC and CRB were activated. The activated motor areas could shift to the area around the lesion, and the non-motor area was activated also.
