Objective To observe the cerebral activation by functional MRI(F MRI) during the thumb movement in different motor fashion. Methods Four stroke patients with hemiplegia were involved in this study During the examination by F MRI, these patients were asked to move thumbs in passive, active and overcoming resistance fashion. Results (1) During the thumb at unaffected side moving in active fashion, functional activity was observed in the contralateral primary motor cortex In passive fashion, however, functional activity was observed in contralateral somatosensory cortex The overcoming resistance motor test was associated with activity in bilateral primary motor cortex and somatosensory cortex (2) The same motor tests were made in movement of the thumb at affected side , functional activity appeared not only in primary motor cortex, somatosensory cortex of affected side, but also in basal ganglia(affected area), frontal lobe, supplementary motor cortex, somatosensory cortex, and contralateral primary motor cortex. Conclusion These results have proved the neurorehabilitation theory such as neuroplasticity and so on

ObjectiveWe discussed the effect of TMS on the motor conduction pathway and studied the function of TMS in the motor function of patients with stroke. Methods65 patients with acute brain infarction were divided into two groups, treatment group given TMS once a day and contral group. Motor nerve center was stimulated twice or three times each day. 14 days were one period of treatment. MEP, CMCT, force and Fugl-Meyer scores were recorded on the first and the last days. Results Before treatment, there was no difference between two groups on CMCT, force and Fugl-Meyer scores. After treatment, the patients in the treatment group got much better improvement in movement ability than the patients in the control group. But there was no difference between two groups on MEP neither before nor after treatment. Conclusions TMS can help patients with stroke to regain movement ability, and improve the recovery of force and fine movement, and also reduce the CMCT distinguishably. TMS is easy to use and no evidently uncomfortable influence on patients happens.

OBJECTIVETo investigate the expression of long noncoding RNA linc00261 in hepatocellular carcinoma (HCC) and its correlation with the clinicopathological features and postoperative outcomes of the patients.

METHODSReal-time fluorescence quantitative PCR (qRT-PCR) was used to detect the expression of linc00261 in surgical specimens of HCC and adjacent tissues from 74 patients. The correlation of the expression level of linc00261 in HCC with the clinicopathological parameters of the patients was analyzed using Chi-square test. The Cox's proportional hazards regression model was used to assess the value of linc00261 in predicting the prognosis of HCC patients after operation. The expression of linc00261 was also examined in 5 HCC cell lines using qRT-PCR. The HCC cell lines MHCC-LM3 and SNU-449 were transfected with small interfering RNAs targeting linc00261 for linc00261 knockdown, and the changes in the cell proliferation, migration and invasion abilities were observed using CCK-8 assay and Transwell assay.

RESULTSThe expression level of linc00261 in HCC was significantly correlated with AFP (=0.032), tumor size (=0.007), microscopic vascular invasion (MVI; =0.01), and TNM stage (=002). The patients with lowered expressions of linc00261 in HCC tissues had a significantly shortened tumor-free survival time ( < 0.05), and a lowered expression of linc00261 was identified as an independent risk factor affecting postoperative recurrence-free survival time of the patients ( < 0.05). In HCC cell lines MHCC-LM3 and SNU-449 cells, linc00261 knockdown obviously promoted the cell migration and invasion ( < 0.01) but did not significantly affect cell proliferation ( > 0.05).

CONCLUSIONSLinc00261 may serve as a new prognostic biomarker for predicting the postoperative outcomes of the patients with HCC.
