ABSTRACT
@#Objective To study the coordination mechanism of brain induced by stimulating on acupoints of different meridians by means of constructing cerebral cortex functional networks reflecting actual brain functional connections. Methods A 128-lead electroencephalogram (EEG) recording and analysis system was used to collect the EEG signals of 14 healthy subjects (eight males and six females) aged 21 to 25 in resting state and magnetic stimulation on the acupuncture points of Guangming (GB37) and Neiguan (PC6) located in different meridians from October to November, 2017. Then EEG sources were localized by group independent component analysis and standard low-resolution brain electromagnetic tomography, and the statistical relationships of EEG components were calculated. Finally, alpha-wave cerebral cortex functional networks were constructed and analyzed based on complex network theory. Results The connections of brain regions associated with movement, vision increased in the stimulation of Guangming acupoint. The brain regions associated with movement, attention and working memory in the stimulation of the Neiguan acupoint were reduced in the network. Some common brain areas were activated and some changes of functional connections were similar. Conclusion The changes in the topological structure of brain networks are basically consistent with the efficacy of the acupuncture point during magnetic stimulation on Guangming and Neiguan of different meridians, however, it causes some similar changes in functional connectivity connections of some brain regions.
ABSTRACT
Objective To study the effect of functional electrical stimulation(FES) with innovative static state combined assistance pattern on lower extremity muscle status,motor function and walking function in children with spastic diplegic cerebral palsy.Methods A total of 40 children with spastic diplegic cerebral palsy were randomly divided into a observation group (20 cases) and a control group (20 cases),which were selected from the Third Affiliated Hospital of Jiamusi University from March 2016 to July 2016.The observation group included 11 males and 9 females,aged 3 to 6 years old,on the average of (4.80 ± 1.06) years;the control group including 7 males and 13 females,aged 3 to 6 years old,with mean age (4.75 ± 0.96) years.The control group was only treated with conventional rehabilitation therapy such as kinesitherapy and occupational therapy.On the basis of routine rehabilitation therapy,the observation group was treated with functional electrical stimulation with innovative static state combined with intelligent assistance patterns.All the therapies including conventional and FES treatment were conducted once per day,5 times per week,total for 8 weeks totally.The outcomes before treatment,4 weeks after treatment and 8 weeks after treatment for all the subserved objects were evaluated by modified Ashworth scale(MAS),including joint range of motion(ROM),manual muscle assessment (MMT),gross motor function scale (GMFM-88 D and E regions),gait analysis and musculoskeletal ultrasound (measured muscle thickness).All the data were collected and analyzed by SPSS 17.0 statistical software.Results After 4 weeks to 8 weeks of treatment,2 groups of children with joint range of motion of lower limbs,muscle strength,muscle tension,GMFM-88 score of D and E regions,muscle thickness and gait in 2 groups of children were improved than those before treatment (P ＜ 0.05),after 4 to 8 weeks of treatment,2 groups of children with lower limb joint activity,muscle strength,muscle tension,GMFM-88 score,D and E regions of the muscle thickness and gait in 2 groups of children were improved than those before treatment,and the differences were significant (P ＜ 0.05).The evaluation index of the observation group,Ashworth [left (1.80 ± 0.52) scores,right (3.40 ± 0.88) scores],ROM [left (19.5 ± 2.8) °,right (19.4 ± 1.5) °],muscle strength [left (1.80 ± 0.52) grade,right (2.O0 ± 0.56) grade] and muscle thickness[left gastrocnemius (32.35 ± 1.79) mm,right gastrocnemius (32.95 ± 2.63) mm,left anterior tibial muscle (30.60 ± 1.00) mm,right anterior tibial muscle (30.05 ± 1.8) mm],were all significantly better than those of the control group (all P ＜ 0.05).Step length (23.75-3.19) cm and step speed (0.45 ± 0.01) m/s compared with the control group improved significantly compared with the control group (P ＜ 0.05),the GMFM scores [D regions (31.30 ± 1.46) scores,E regions (48.95 ± 1.40) scores] was significantly higher than those of the control group (P ＜ 0.05).Conclusions The FES with innovative static state combined with intelligent assistance pattern can effectively improve the lower limb muscle state and motor function in children with spastic diplegic cerebral palsy.
ABSTRACT
Objective@#To investigate the association between D-dimer levels and clinical events in patients with mechanical heart valve replacement under oral anticoagulation therapy.@*Methods@#This prospective study included 640 consecutive patients underwent mechanical heart valve replacement in Wuhan Asia Heart Hospital between January 2013 and June 2014.Patients were assigned to abnormal D-dimer group (D-dimer level>cut off value, n=88) and normal D-dimer group (D-dimer level≤cut off value, n=552) according to D-dimer levels measured at 3 months after the initiation of oral anticoagulation therapy.All patients were followed up for 24 months or until the observation of the end points, which included thrombotic events, bleeding events and all-cause deaths.The anticoagulation therapy was monitored once per 1-2 months by the international normalized ratio (INR), and the target value was 1.8-3.0.@*Results@#During a follow-up period of 24 months, rates of total clinical events (19.30%(17/88) vs. 5.8%(32/552), P<0.01), thrombotic events (11.4%(10/88) vs. 2.3%(13/552), P<0.01), and all-cause deaths (8.0%(7/88) vs. 2.0%(11/552), P<0.01) were all significantly higher in abnormal D-dimer group than in normal D-dimer group.There were no significant difference in bleeding events between the two groups (2.3%(2/88) vs. 3.1%(17/552), P=0.77). Multivariate Cox regression analysis showed that high D-dimer level was an independent risk factor of total clinical events (HR=3.86, 95%CI 1.92-7.76, P<0.01), thrombotic events(HR=5.29, 95%CI 2.12-13.10, P<0.01), and all-cause deaths(HR=5.32, 95%CI 1.71-16.60, P<0.01), but which was not correlated with bleeding events(HR=1.36, 95%CI 0.27-6.84, P=0.71).@*Conclusion@#Elevated D-dimer levels are linked with clinical events in patients with mechanical heart valve replacement under oral anticoagulation therapy.
