RESUMO
Objective To investigate the clinical efficacy of contralateral acupuncture in treating motor dysfunction in patients with acute ischemic stroke.Methods Sixty patients with acute ischemic stroke were randomized to treatment and control groups, 30 cases each. Both group received electroacupuncture in addition to conventional rehabilitation training. Besides, the treatment group received electroacupuncture at points on the healthy side in the morning and on the affected side in the afternoon and the control group, electroacupuncture at points on the affected side in both the morning and afternoon. Motor function was assessed using the Fugl-Meyer Assessment (FMA), the modified Barthel Index (MBI), integrated electromyography (iEMG) and median frequency (MF) in the two groups of patients before and after treatment.Results There were statistically significant pre-/post-treatment differences in the FMA score, the MBI score, iEMG and MF in the two groups (P<0.01). There were statistically significant post-treatment differences in the FMA score, the MBI score and iEMG between the treatment and control groups (P<0.01,P<0.05).ConclusionContralateral and healthy side acupuncture can markedly improve motor function in acute stroke patients.
RESUMO
[ Objective ] To observe the effect of kaolin and propranolol on paraquat ( PQ ) concentration in the lungs of poisoned mice. [ Methods] A group of 144 ICR mice were randomly divided into 3 groups:PQ, treatment, and control.Then 100 mg/kg PQ were intragastrically administrated ( ig) in PQ group and treatment group, while only the same volume normal saline was given in control group.And then 48 g/kg kaolin combined with 3.2 mg/kg propranolol were administered in treatment group immediately after poisoning while only the same volume of normal saline was given in the other two groups. Pathological examination was done and PQ concentration in lungs of the mice detected 0.5 h, 1 h, 2 h, 4 h, 6 h, 8 h, 12 h, 24 h after poisoning. [ Results] In the lungs of the mice in PQ group occurred alveolar capillary expansion, endothelial cell swelling, small or large sheet-shaped inflammation cell infiltration and mainly neutrophils while in treatment group the above lesions were apparently alleviated.In PQ and treatment groups, PQ concentration in lungs of both groups rose significantly 0.5 h after poisoning and up to peak at 4 h.But PQ concentration in lungs decreased significantly in treatment group from 4 h to 24 h after poisoning ( P<0.05) , as compared with that in PQ group. [ Conclusion] PQ concentration in lungs of the poisoned mice was decreased and the injury alleviated when they were treated with kaolin combined with propranolol.It is held that further research is worth doing in clinical practice.
