Objective To explore the correlations of diffusion-weighted imaging (DWI) types and the degree of neurologic impairment in acute ischemic stroke patients with atrial fibrillation.Methods DWI images and National Institutes of Health Stroke Scale(NIHSS) of 186 patients with acute ischemic stroke patients with atrial fibrillation were collected retrospectively.The correlation of DWI features and NIHSS was analyzed.Results On DWI,all acute ischemic stroke patients with atrial fibrillation presented high signal intensity.Single cortex-subcortical infarction mostly appeared in the anterior circulation(94,50.5%);Multi-infarction commonly occurred in the posterior circulation(18,13.0%);The neurological deficit scores of subcortical-cortex infarction in the left anterior circulation(16.75±7.10) were higher than that in the right side(13.50±5.70)(P<0.05).The neurological deficit scores of cortex-subcortical infarction in the posterior circulation (6.38±2.03) were significantly lower than that in the multi-infarction (16.77±8.90) (P<0.05).Conclusion DWI types are valuable for etiological diagnosis in ischemic stroke.Combination with NIHSS score could provide a basis for clinical individual treatment programs selection and prognostic evaluation.

Objective To explore the effect of nursing support on negative emotion and quality of life in patients with brain tumor. Methods A total of 139 cases of brain tumor in Shandong Provincial Cancer Hospital of Shandong University from September 2014 to February 2016 by convenient sampling , according to the random number table, they were divided into the control group and the intervention group. The patients in the control group were given routine discharge follow-up, while the patients in the intervention group were given emote team nursing support on the basis of the control group. We used anxiety self rating scale (SAS), depression self rating scale (SDS) and quality of life assessment scale (QLICP-BN) evaluation two groups of patients with anxiety, depression and quality of life level in the patients when they were discharged from hospital and discharged after 1 month, 3 months. Results Comparing the two groups of patients with anxiety and depression level and quality of life in the hospital, there was no statistically significant difference (t=0.187,0.174, P > 0.05);1 month after discharge, the scores of SAS and SDS respectively (62.97 ± 485), (63.83 ± 5.24) points in the intervention group, the scores of SAS and SDS respectively (64.58 ± 5.15), (65.17 ± 5.11) points in the control group, the difference is statistically significant (t=2.753, 2.321, P<0.05);3 month after discharge, the scores of SAS and SDS respectively(61.04±4.13),(62.25±3.95)points in the intervention group, the scores of SAS and SDS respectively(63.91 ± 4.73),(64.83 ± 4.29)points in the control group, the difference is statistically significant (t=4.621,5.196, P < 0.01); 1month, 3 months after discharge, the total quality of life scores respectively (65.28 ± 12.53), (68.71 ± 12.78) points in the intervention group, the total quality of life scores respectively (62.07 ± 11.27), (63.86 ± 12.13) points in the control group, the difference is statistically significant (t=2.439, 3.803, P < 0.01). The intervention effects and time effects of anxiety, depression and quality of life were statistically significant (W Mauchly's were 0.823, 0.782, 0.757, P <0.05). Conclusions Remote team nursing support can effectively reduce the negative emotions of patients with brain tumor, improve the quality of life, can be used in the department to promote the quality of clinical care.

The evaluation tools were developed based on the theory of validity,the development process and results of the Manual of Home-Based Rehabilitation Mode for Stroke Patients were evaluated by a panel of experts,and the opinions and suggestions for improvement were collected from the evaluation experts.The results showed that the average score for development process and results of the manual were ＞4 points in structural validity,content validity and surface validity,indicating that the manual was of high quality,and the development of the manual was scientific and the results were practical.The manual may provide the guidance for the home-based rehabilitation in community.At the same time,this study has enriched the reviewing tools and evaluation method of manuals,and provided reference for the peers.

MicroRNA is a class of short-chain non-coding RNA that regulates gene expression at post-transcriptional level.It can participate in the pathophysiology processes of tumor regulation,neurodegenerative disease,and cardiovascular disease.Recent studies have shown that microRNA can play a reguhtory role in ischemic brain damage through autophagy.This article reviews the effect of microRNA on autophagy after cerebral ischamia and its possible mechanisms.
