RESUMO
To observe therapeutic effect of continuous rehabilitation exercise combined low‐frequency e‐lectrical stimulation on patients with low extremity dysfunction after ischemic stroke and its influence on patients＇lower extremity muscle strength and neurological motor function .Methods : A total of 94 patients with lower ex‐tremity dysfunction after ischemic stroke were randomly and equally divided into electrical stimulation group (re‐ceived low frequency electrical stimulation ) and combined treatment group (received continuous rehabilitation exer‐cise based on electrical stimulation group ).Therapeutic effect after three‐month treatment , lower extremity muscle strength and neurological motor function before and after treatment were evaluated , compared and analyzed be‐tween two groups .Results : After treatment , total effective rate of combined treatment group was significantly higher than that of electrical stimulation group (87. 23% vs.68.09%, P＝0.026).Compared with electrical stimu‐lation group after treatment , there was significant reduction in lower extremity muscle strength score [ (1.96 ± 0.45) scores vs .(1. 43 ± 0. 41) scores] , significant rise in scores of Fugl‐Meyer movement scale [FMMS , (24. 54 ± 3.76) scores vs.(29. 98 ± 3. 82) scores] , Barthel index of activities of daily living (ADL ) [BI , (69. 02 ± 6.29 ) scores vs .(79. 46 ± 6. 35 ) scores] , Berg balance scale [BBS , (44.56 ± 5.71 ) scores vs .(52.14 ± 5.79 ) scores] , Holden walking function [ (3.92 ± 0. 46) scores vs .(4.61 ± 0.49) scores] and Tinetti gait analysis [ (6. 57 ± 1.13) scores vs .(8. 06 ± 1. 24) scores] in combined treatment group , P＝0.001 all.Conclusion : Continuous rehabilitation exercise combined low frequency electrical stimulation can significantly enhance lower extremity muscle strength , improve neurological motor function , improve ADL in patients with lower extremity dysfunction after ischemic stroke , which is worth extending .
RESUMO
Fourteen psychrotrophic bacteria were isolated from swamp soil collected in Ruoergai plateau wetland,and their generation time and degrading ability of livestock wastewater CODcr was determined.The results showed that the generation time was within 4.9 h to 11.6 h.Based on the generation time,9 psychro-trophic strains(NLJ1,NLJ6,NLJ7,NLJ9,NLJ10,NLJ11,NLJ12,NLJ13 and NLJ14),whose generation time was within 4.9 h to 5.6 h,were chosen to treat livestock wastewater.The results suggested that these 9 strains had different CODcr disposal ability when treating livestock wastewater singly at 6?C for 6 h,and strains NLJ6,NLJ7,NLJ9,NLJ10,NLJ11 and NLJ13 had good ability to degrade livestock wastewater,the CODcr degrading rate was about 60%~70%,hence,they were used as high efficient strains;However,the CODcr degrading rate of the other strains was less than 50%.After inoculating mixture culture of these six strains into the distilled livestock wastewater,after 6 h's treating,the CODcr degrading rate reached to 85.42%.Furthermore,activated sludge collected from Yaan,Dujiangyan and Chengdu were inoculated by the mixture culture of those six strains,and used to treat livestock wastewater for 6 h.The results showed that the average CODcr degrading rate was 81.67%,76.32% and 70.56%,respectively;Variance analysis showed that there was no significant differentiation between each treatment,which revealed that those six psychrotrophic strains had good adaptability to different source of activated sludge.
