Chinese Journal of General Practitioners 2008;7(10):671-673
Objective To study the effects of aerobic exercises on platelet function in patients with phase Ⅰ essential hypertension (EH). Methods Low-intensity aerobic exercises therapy was given to 36 patients with phase Ⅰ EH for three months. Changes of their blood pressure, heart rate, platelet aggregation rate (PAGTmax), alpha-granule membrane protein (GMP-140) and mean platelet volume (MPV) werer ecorded and compared to those in 36 normal healthy controls. Results As compared to those in controls,PAGTmax, level of GMP-140 and MPV were all increased in patients with phase Ⅰ EH before exercises therapy(t=15.221, 10. 916 and 16. 401, respectively, all P < 0. 01 ). After exercises therapy, 24-hour mean blood pressure decreased in association with reduction in PAGTmax to (0. 80±0. 05)% from (0. 88±0. 08) % (t=4. 323, P < 0. 05), level of GMP-140 decreased to ( 28±20) μg/L from (57±23 ) μg/L ( t=15.049, P<0.01) and MPV decreased to (9.0±0.9)fl from (9.1±0.9)fl (t=5.518, P <0.05) before it. But, there was no significant difference in these in dicators of platelet function in controls before and after exercise therapy (P>0.05). Conclusions Aerobic exercises therapy could be effective in lowering blood pressure in patients of mild EH with increased platelet activation, as well as inhibition ontheir platelet activation.

ObjectiveTo assess how transcranial electrical stimulation (TES) concurrent with rehabilitation training influences brain plasticity and behavioral functional performance in rats following a focal ischemic infarction.MethodsAfter an acute focal ischemic infarction by transient occlusion of right middle cerebral artery (MCAO), the electric stimulation concurrent with rehabilitation group was given TES, balancing and rotating and walking exercise everyday; the rehabilitation group was given only balancing and rotating and walking exercise everyday; the control group received no treatment. Growth associated protein 43(GAP-43) was examined by immunohistochemical techniques, and density of reaction product and forelimb placing test (FPT) were measured on the 3rd, 7th, 14th and 28th day after infarction respectively.ResultsThe electrical stimulation concurrent with rehabilitation group provided marked improvement in FPT on the 7th, 14th and 28th day compared with the rehabilitation group and the control group (P<0.01~0.05). The GAP-43 demonstrated statistically significant increase on the 3rd, 7th, and 14th day in the peri-infarct region in the electrical stimulation concurrent with rehabilitation group compared with other two groups(P<<0.01~0.05).ConclusionThe efficacy of transcranial electrical stimulation combining with rehabilitation training can improve functional outcome and neuronal plasticity following ischemic cerebral damage. The mechanism may be partly due to the upregulation of the expression of GAP-43 in the peri-infarct region. Meanwhile, the efficacy is superior to rehabilitation training only.
