Unilateral spatial neglect is recognized as a significant disabling deficit, clinically defined as a failure to report, respond or orient to novel stimuli presented on the side opposite to a brain lesion. It is a predictor of poor functional outcome following right hemisphere lesion. Many different rehabilitation techniques or treatments have been put forward to alleviate, reduce or remediate spatial neglect. In the following review, we described, explained these Methods in terms of their underlying or motivatng mechanisms and evaluated in terms of the current evidence base for their effectiveness for clinical rehabilitation.

To understand the present situation of sport participation in community residents of Shanghai，study infecting factors to the regular sport participation rate and evaluate recognition degree of the relationship of sport and chronic disease，we carried out questionnaire survey indoors among the permanent residents,aged 35～74,in East Nanjing Road community, including survey on chronic disease and sport participation situation. The material was statistically analyzed and the related factors were proved by x2 test. The results showed that in 1457 permanent residents,470 regularly participat in sport, and were classified as sport population. The prevalence was 32.3%.The gender, age, education level, occupation and chronic disease had statistical significance (P<0.05) and they were probably infecting factors of the regular sport participation rate. Currently,the regular sport participation rate in community is relatively high and the purpose of sport participation was evident, however, the age structure of sport population was imbalance. The sport participation in residents was individualized and without proper scientific instruction.

BACKGROUND: Cervical spondylosis is a common disease in middleaged and elderly people. There are many methods of rehabilitative treatment such as traction, massage, medical gymnastics, acupuncture and local blocking, etc.OBJECTIVE: To observe the effects of rehabilitative exercise on patients with cervical spondylosis by way of quantitative generalized boxing exercise combined with local cervical medical exercise.DESIGN: Self-control study on patients with cervical spondylosis in the community for 3 monthsSETTING: Department of Rehabilitation Medicine, Huashan Hospital Affiliated to Fudan University PARTICIPANTS: The indoor questionnaire investigation about chronic diseases in community was carried out on 1 457 inhabitants with the age from 35 to 74 in a community of South Nanjing district, Shanghai in order to check out the patients with cervical spondylosis who had been diagnosed confirmatively by hospital and exclude the patients with the disease of spinal cord type. There were total 114 patients volunteering to participate in the 3-month rehabilitative treatment with an informed content, including of 12 with cervical type of the disease, 39 with nerve root type, 23 with vertebroarterial type, 5 with sympathetic nerve type, 35 with mixed type and none with spinal cord type.METHODS: 3-month rehabilitative exercise was carried out for the 114 patients with cervical spondylosis.① One or several kinds of generalized boxing exercise such as shadow boxing, eighteen-gesture training practice and joint exercise were chosen by the patients according to their own in terest and physical energy. It was required that patient exercise was done for 3 months with one time a day, and each time for no less than 30 minutes, with the intensity after each exercise arriving to the target heart rate level of 170 subtracting their age. ② Aiming to exercise the cervicalshoulder part and to relax its related functions, the local cervical medical exercise has 12 procedures including turning left and right, moving neck around, shrinking head and relaxing shoulders, stretching neck and extending back, turning head and watching the moon, waving arms, putting up arms, lifting chest and squaring elbows, and trying hard to stretch neck.It was required that each procedure be repeated 5 to 10 times at the beginning and later more times increasing gradually, and the whole set of exercise be practiced for 3 months with lor 2 times each day and each time lasted at least 10 minutes.③No other treatment was performed by the patients except for the above exercise intervention. The effects were evaluated after 3 months.MAIN OUTCOME MEASURES: ①The evaluated results of the curative effect in all patients with 3-month rehabilitative exercise.② Relationship between types of cervical spondylosis and curative effect ③ Relationship between course of disease and curative effect RESULTS: According to the intention-to-treat analysis, all the 114 patients persisting in the 3-month exercise intervention entered the result analysis. The curative effect evaluation: among the 114 patients, 44 were with the general curative effect, 40 with marked improvement, 25 with improvement, 5 with inefficacy. The percentage of the general curative and marked improved is 73.7%, and that of total improvement is 95.6% The clinical manifestations of all patients with cervical spondylosis including cervicoscapulargia, radioactive numb and pain in unilateral or bilateral upper arms, dizziness, tinnitus, headache, etc.were distinctively improved ② Relationship between the types of cervical spondylosis and curative effect: after 3-month treatment of rehabilitative exercise, the percentage of the general curative effect and marked improvement in patients with cervical type and nerve root type was higher than that in patients with verteboarterial type, sympathetic nerve type and mixed type (91.7%,97.4%, 47.8% ,20.0% ,65.7% respectively and p value below 0.01). ③ Relationship between the course of cervical spondylosis and curative effects: the percentage of the general curative effect and marked improvement in patients with the course of less than one year is 90.9% and that in patients with the course of 1 to 5 years is 88.6%, which were all higher than that in patients with a course of 5 more years (p value below 0.01).CONCLUSION: Quantitative generalized boxing exercise combined with local cervical medical exercise is helpful to improve the radiculopathy symptoms, but only combined with other treatments could patients with vertebroarterial type receive the best curative effect. In addition, there is a certain relation between the course of disease and curative effect, and patients with cervical spondylosis should be treated with rehabilitative exercise as early as possible, which suggestes that it is worthy of popularization that patients with cervical spondylosis are organized to practice quantitative boxing exercise combined with cervical medical exercise in the community.

Objective To explore the factors influencing the functional recovery of patients with spinal cord injury (SCI) at discharge. Methods A total of 105 patients with SCI admitted to the rehabilitation medicine department at Huashan Hospital between December 2004 and October 2009 were studied. Data on eleven variables were collected including the patients' medical history, physical examination results and American Spinal Injury Association (ASIA) scores at admission. Functional status was registered according to the modified Barthel index (MBI) assessed at admission and before discharge. Linear regression analysis was used to assess the influence of the variables.Results After rehabilitation, average MBI and ASIA scores were significantly higher. The multiple regression analysis revealed that injury grade, motor and pinprick sensation scores at admission were related to MBI before discharge.The duration of rehabilitation, the rehabilitation treatment course and motor scores at admission were related to MBI increases during hospitalization. Conclusions Patients with different ages, injury levels and severity can improve their functional abilities through rehabilitation treatment, especially patients with better initial motor ability, longer treatment and earlier intervention.

ObjectiveIn order to study the effect of three-month rehabilitation on motor function in hemiplegics after stroke. Methods125 patients were randomly divided into two groups, rehabilitation group (72 cases)and control group(53 cases).Patients in the rehabilitation group were given clinical treatment,electric stimulation therapy(EST) and regularly physical therapy, while those in control group were given clinical treatment and unguided self-training, and the evaluation was done in pre-treatment and post-three-month respectively. Motor function was assessed in Fugl-Meyer Assessment(FMA).ResultsMotor scores in each group had a more significant difference(P<0.001)before and after treatment, the process of scores in the rehabilitation group was obviously superior to that in the control group(P<0.001). Conclusions Rehabilitation training on hemiplegics after stroke may obviously improve motor function, depressing the disability and increasing the living quality.

Objective To assess differences in brain activation between active and passive movement of the right hand using blood oxygen level-dependent functional magnetic resonance imaging (BOLD-fMRI). Methods Nine healthy adult right handed volunteers were studied. fMRI was performed with active and passive finger-to-finger movement. Results Right hand active and passive movement produced significant activation in the contralateral sensorimotor cortex ( SMC ), the contralateral premotor cortex ( PMC ), bilaterally in the supplementary motor area (SMA) and in the ipsilateral cerebellum. The activated brain areas were centered on the contralateral SMC and PMC and located more forward during active movement than during passive movement. The contralateral SMC was the most strongly and the most frequently activated brain area. The contralateral posterior parietal cortex (PPC) was less relevant to the hand movements. Unlike active movement, passivemovement activated more areas in the posterior central gyrus than in the anterior central gyrus. Conclusions Both active and passive movement significantly activate the brain areas which are responsible for hand movement, but there are some differences in the locations of the cortex areas activated and in the incidence activation except in the contralateral SMC.

OBJECTIVE To investigate the inhibitory effect of eight lignan compounds of Fructus Schisandrae chinensis in vitro on carboxylesterase 2 (CES2) and to estimate the herb-drug interaction (HDI) risks of strong CES2 inhibitors selected from the above compounds. METHODS Fluorescein diacetate (FD) was employed as a specific fluorescent probe of CES2. The residual activity of CES2 was detected in human liver microsomes after the intervention with deoxyschizandrin, schisanhenol, schisantherin E, schisandrol A, schisandrol B, gomisin J, gomisin G, and gomisin O at 37℃ for 10 min, respectively. 1% DMSO served as control. Residual activity of CES2 was assessed with metabolite production of FD detected by fluorescent intensity, combined with IC50 values of the above compounds to predict HDI risks between lignans and CES2-metabolizing drugs. RESULTS Compared with control group, the activity of CES2 was significantly inhibited by deoxyschizandrin and schisanhenol (P<0.01), with IC50 values of 8.06 μmol · L- 1 and 8.91 μmol · L- 1, respectively. The other six lignans compounds exhibited mild inhibitory effect on CES2. HDI risk prediction of deoxyschizandrin or schisanhenol indicated that exposure of CES2-metabolizing drugs might increase 11.24 and 0.40 times, respectively. CONCLUSION Deoxyschizandrin and schisanhenol exhibit strong inhibitory effects against CES2 in vitro so that potential HDI risks should be taken into account during administration of drugs containing Fructus Schisandrae chinensis.

Objective To investigate the underlying mechanism of motor recovery of the hemiplegic lower extremity in stroke patients. Methods The brain activation pattern during sequential extension-flexion of the affect-ed knee of 7 stroke patients and 8 healthy subjects was observed by blood-oxygen- level-dependent fMRI (BOLD-fM-RI) and analyzed by microsoft SPM5. Results When executing unilateral knee flexion-extension, contralateral paracentral lobe and contralateral supplementary motor area and right temporal gyms and inferior parietal lobes of both sides were significantly activated in all the healthy subjects, while the ipsilateral parietal lobe BA7 and BA5 were sig-nificantly activated in 6 of the 7 stroke patients. Conclusions Sequential extension-flexion of the affected knee of stroke patients was probably dependent on the activation of BA7 and BA5 in the intact side. Compensatory activation of the intact hemisphere might be one of the main mechanisms for the paretic lower extremity motor recovery in stroke patients.

Objective To investigate whether physical training can activate the PI3K/Akt (phosphatidyli-nositol 3-kinase/Protein Kinase B) signal transduction pathway after focal brain isehemia, leading to the reduction ofendothelial cell apoptosis. Methods Twenty-four male adult Sprague-Dawley rats (2 ～ 3 month old, n = 24) weresubjected to 60-min right middle cerebral artery occlusion (MCAO). All rats were randomly assigned to one of thethree groups: physical training group, control group and sham operation group. 24 hours after MCAO ,physical train-ing group underwent 30 min treadmill training per day for 2 weeks. Results After two weeks, the phosphorylationlevel of PI3K/Akt in the physical training group was significantly higher when compared with that in the control group(P <0.05), while the expression level of Bax in physical training group was lower when compared with that in thecontrol group( P < 0.05 ). Conclusion Physical training can activate PI3K/Akt signal transduction pathway,which may be associated with the neurological recovery.

Objective To assess any differences in brain activation during active,passive and imaginary movement of the hands using blood oxygen level-dependent functional magnetic resonance imaging (fMRI),and to provide references for the cortical reorganization in patients with brain injuries.Methods Twenty healthy,righthanded,adult volunteers were studied,fMRI was performed during active,passive and imaginary fist clutching.Whole brain analysis and group analysis were applied to get the voxels,the volume of activation,the peak t-score and its coordinates.Results Active and passive movement both produced significant activation in the contralateral sensorimotor cortex,the contralateral supplementary motor area and the ipsilateral cerebellum.The sensorimotor cortex was the most frequently and most strongly activated brain area.Imaginary movement produced significant bilateral activation in the supplementary motor area.Conclusions Active and passive movement induce similar brain activation patterns.This indicates that passive might replace active movement when observing activation of the brain's cortex during the rehabilitation of patients with hemiplegia.
