RESUMEN
It was discussed about the way of teaching base construction and teachers training for the rehabilitation therapy, including the self-training, domestic and international studies, cooperation with Taiwan Chung Shan Medical University and the first-level hospitals in Guangdong. It resulted in the improvement of the levels of education and academic title of the teathers, and development of teaching bases.
RESUMEN
Objective To investigate the effects of functional electrical stimulation (FES) on motor function and the expression of bromodeoxyuridine (Brdu) + and glial fibrillary acid protein (GFAP) + in the subventricular zone (SVZ) of rats with acute cerebral infarction,and to explore it's mechanism. Methods A rat model of cerebral infarction was established using Longa's technique for middle cerebral artery occlusion (MCAO) with an intraluminal filament.The rats were randomly divided into a FES group,a placebo stimulation group and a control group.In each group,rats were randomly allocated into 1 d,3 d,7 d and 14 d subgroups (6 rats/subgroup).Superficial electrodes were pasted on the paralyzed forelimbs of rats in the FES group for connecting with the FES instrument,and FES treatment was carried out with a current of 4-5 mA for 15 min on the third day after the MCAO operation to produce extension of the wrist and the digits of the paralyzed forelimb.The rats in the placebo stimulation group were pasted with electrodes,but no FES was administered and they received no other treatment.Neurological deficits were evaluated using the modified neurological severity score (mNSS) before treatment and on the 1 st,3rd,7th,and 14th day after treatment. BrdU and GFAP positive cells in the SVZ were detected by immunofluorescence techniques.Results After 7 or 14 days the motor function of rats in the FES group had improved significantly compared with the placebo stimulation and control groups.Compared with the other two groups,the expression levels of BrdU+ and GFAP+ cells in the ischemic SVZ in the FES group were significantly higher at the 3rd,7th and 14th day.Conclusion FES can improve motor function after acute cerebral infarction and also promote the proliferation and differentiation of neural stem cells in the SVZ.
RESUMEN
Objective To study the effects of functional electric stimulation(FES) on neural function recovery and expression of nestin around cerebral infract area of rats with acute stroke.Methods The model of middle cerebral artery occlusion(MCAO) of male adult SD rats was established with the method of modified intraluminal filament occlusion.Sixty successfully established model rats were randomly allocated into FES group, placebo group and control group(20/group).Three days after MCAO' s surgery, rats in FES group were treated with FES device while the ones in placebo stimulation group were treated with the same FES device but without electrical output.Rats in control group had no treatment.All groups were randomly assigned into 4 subgroups according to treatment time:1 d,3 d ,7 d and 14 d (5/subgroup).The modified neurological severity score(mNSS) was adopted to evaluate neural function recovery before and after treatment in 4 time points as mentioned above.Meanwhile,the nestin expression in various time points was detected by immunohistochemistry stain in distant area of ipsilateral cortex of infarction.Results The mNSS sours in FES group is lower than that in placebo simulation group and control group at the 7 thd and 14thd (P < 0.05 ) ;The expression of nestin-positive cells in distant area of ipsilateral cortex of infarction of rats in FES group is higher than that in placebo stimulation group and control group ( P < 0.05 ).Conclusions FES may improve the recovery of neural function in the earlier stage of cerebral infarction.FES treatment could improve the expression of nesitin around cerebral infarct area and it could be one of the mechanisms of FES' s effect.
