The cortical activation pattern during bilateral arm raising movements

Neural Regeneration Research 2017年第2期12卷 317-320页

作者： Sung Ho Jang Jung Pyo Seo Seung-Hyun lee Sang-Hyun Jin Sang Seok yeo Department of Physical Medicine and Rehabilitation College of Medicine Yeungnam University Daegu Republic of Korea Robot System Research Division Daegu Gyeongbuk Institute of Science & Technology Daegu Republic of Korea Department of Physical Therapy College of Health Sciences Dankook University Cheonan-si Chungnam Republic of Korea

Bilateral arm raising movements have been used in brain rehabilitation for a long time. However, no study has been reported on the effect of these movements on the cerebral cortex. In this study, using functional near infrared spectroscopy（f NIRS）, we attempted to investigate cortical activation generated during bilateral arm raising movements. Ten normal subjects were recruited for this study. f NIRS was performed using an f NIRS system with 49 channels. Bilateral arm raising movements were performed in sitting position at the rate of 0.5 Hz. We measured values of oxyhemoglobin and total hemoglobin in five regions of interest： the primary sensorimotor cortex, premotor cortex, supplementary motor area, prefrontal cortex, and posterior parietal cortex. During performance of bilateral arm raising movements, oxyhemoglobin and total hemoglobin values in the primary sensorimotor cortex, premotor cortex, supplementary motor area, and prefrontal cortex were similar, but higher in these regions than those in the prefrontal cortex. We observed activation of the arm somatotopic areas of the primary sensorimotor cortex and premotor cortex in both hemispheres during bilateral arm raising movements. According to this result, bilateral arm raising movements appeared to induce large-scale neuronal activation and therefore arm raising movements would be good exercise for recovery of brain functions.

OBJECTIVE: To investigate the effectiveness of acupuncture in the treatment of chronic schizophrenia and co-morbid sleep ***: A 42-year-old German male outpatient,suffering from long-term schizophrenia and sleep disorders, entered the study. Acupuncture was used as a non-pharmacological intervention. In addition to his ongoing Western Medicine(pharmacological) treatment, the patient received 12 weekly(non-standardized) acupuncture treatments in the clinic. The Traditional Chinese Medicine(TCM) diagnosis, the psychological assessment and the actiwatch data were compared before and after the acupuncture ***: The TCM diagnosis revealed a Liver Fire pattern before the acupuncture treatment, which was still present, although to a lesser degree, after the treatment. The psychological assessment revealed no change in the positive symptoms, but a small decrease in the negative symptoms and the general psychopathology of the patient. This was further illustrated by the small decrease in the number of depressive symptoms. The subjective sleep disorders improved markedly after acupuncture treatment, but the daytime sleepiness did not. The actiwatch results showed that after acupuncture treatment, the patient was moving less during sleep, but no significant results were found for the other sleep ***: Acupuncture was found to be an effective non-pharmacological add-on method for treating subjective sleep disorders, and, to a lesser degree, objective sleep disorders and the negative symptoms of chronic schizophrenia. Future larger clinical trials with follow-up measurements are needed in order to replicate the present preliminary beneficial acupuncture findings and in order to determine whether the observed effects can be sustained.

Clinical usefulness of ankle brachial index and brachial-ankle pulse wave velocity in patients with ischemic stroke

引用

The Journal of Biomedical Research 2016年第4期30卷 285-291页

作者： Hyung-Suk lee Hye Lim lee Ho-seong Han Minju yeo Ji Seon Kim Sung-Hyun lee Sang-Soo lee Dong-Ick Shin Department of Neurology Yuseong Sun General Hospital Daejeon 34084 Korea Department of Neurology Chungbuk National University College of Medicine Chungbuk National University Hospital Cheongju 28644 Korea

Ankle brachial index （ABI） and brachial-ankle pulse wave velocity （baPWV） are widely used noninvasive modalities to evaluate atherosclerosis. Recently, evidence has increased supporting the use of ABI and baPWV as markers of cerebrovascular disease. This study sought to examine the relationship between ABI and baPWV with ischemic stroke. This study also aimed to determine which pathogenic mechanism, large artery disease （LAD） or small vessel disease （SVD）, is related to ABI or baPWV. Retrospectively, 121 patients with ischemic stroke and 38 subjects with no obvious ischemic stroke history were recruited. First, ABI and baPWV were compared between the groups. Then, within the stroke group, the relevance of ABI and baPWV with regard to SVD and LAD, which were classified by brain magnetic resonance image （MRI） and magnetic resonance angiography （MRA） or computed tomography angiography （CTA） findings, was assessed. The baPWV was higher in the stroke group than non-stroke group （1,944.18±416.6 cm/s vs. 1,749.76±669.6 crn/s, P 〈 0.01）. Regarding LAD, we found that mean ABI value was lower in the group with extracranial large artery stenosis （P 〈 0.01）, and there was an inverse linear correlation between ABI and the grade of extracranial large artery stenosis （P〈 0.01）. For SVD, there was a significant correlation between SVD and baPWV （2,057.6±456.57 cm/s in the SVD （＋） group vs. 1,491±271.62 cm/s in the SVD （-） group; P 〈 0.01）. However, the grade of abnormalities detected in SVD did not correlate linearly with baPWV. These findings show that baPWV is a reliable surrogate marker ofischemic stroke. Furthermore, baPWVand ABI can be used to indicate the presence of small vessel disease and large arterial disease, respectively.

BACKGROUND Recently, the American Association for the Study of Liver Disease suggested no preference between tenofovir(TDF) and entecavir(ETV) regarding potential long-term risks of renal complications. Over the years, renal safety has become a critical concern in nucleos(t)ide analog-treated patients due to the long-term use of these drugs. However, existing studies do not show significant differences in renal dysfunction between these two drugs. Further, there is a paucity of studies comparing the long-term renal effects of TDF and *** To investigate the effects of TDF and ETV on renal function, we performed systematic review and *** Two investigators independently searched the Cochrane Library, MEDLINE, and Embase databases for randomized controlled trials and nonrandomized studies(NRSs) using the keywords 'CHB', 'Tenofovir', and 'Entecavir', and additional references were obtained from the bibliographies of relevant articles published through December 2017. The quality of each study was assessed using the Newcastle-Ottawa scale and the Grading of Recommendations Assessment,Development and Evaluation criteria. The primary outcome was the change in serum creatinine level in the TDF and ETV groups at baseline, 6 mo, 12 mo and24 *** NRSs comprising 2263 participants met the inclusion criteria. Changes in creatinine levels were higher in the TDF group than in the ETV group at 6 mo[mean difference(MD) = 0.03 mg/dL;95%CI: 0.02-0.04;I2 = 0%], 12 mo(MD =0.05 mg/dL;95%CI: 0.02-0.08;I2 = 78%), and 24 mo(MD = 0.07 mg/dL;95%CI:0.01-0.13;I2 = 93%). The change in estimated glomerular filtration rate(eGFR) was significantly higher in the TDF group than in the ETV group at 6 mo[standardized mean difference(SMD),-0.22;95%Cl:-0.36--0.08;I2 = 0%], 12 mo(SMD =-0.24;95%Cl:-0.43--0.05;I2 = 50%), and 24 mo(-0.35;95%Cl:-0.61--0.09;I2= 67%).CONCLUSION TDF statistically significantly increased serum creatinine levels and decreased the eGFR in 6-24 mo compa
