Abstract Background The exosomal miRNAs have been emerged as biomarkers and therapeutic targets for various diseases, however, the function of exosomal miRNAs in stroke remains largely unknown. Methods The blood samples from acute ischemic stroke (AIS) patients and normal controls were collected. The exosomes were isolated from the blood samples, which were confirmed by electron microscopy and western blot with the specific exosomes biomarker CD9, CD63 and Tsg101. Results RT-qPCR analysis showed that exosomal miR-134 was significantly increased in AIS patients within 24 h after stroke onset compared with that of control group. Highly expressed exosomal miR-134 was correlated with the National Institutes of Health Stroke Scale (NIHSS) scores, infarct volume and positively associated with the worse prognosis of the stroke patients. Additionally, the exosomal miR-134 was strong positively correlated with the expression of serum interleukin 6 (IL-6) and plasma high-sensitivity C relative protein (hs-CRP). The receiver operating characteristic (ROC) curve suggested that miR-134 might be a potential factor to discriminate AIS patients from non-stroke controls. Conclusions The exosomal miR-134 as a possible novel biomarker for the diagnosis and prognosis of stroke.

Purpose: To investigate the use and applications of Internet cloud technology to construct a network management model for statin therapy in Alzheimer's disease in Hainan Province. Method: Randomized controlled trials (RCTs) investigating the prevention and treatment of Alzheimer's disease (AD) with statins were employed in this study. Computerized searches were conducted using PubMed, EM-BASE, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), WANFANG Data, and Curriculum-Based Measurement (CBM) retrieval systems, with a retrieval timeframe of April 2012. After literature screening, data extraction, and quality evaluation, Meta-analysis was performed using Review Manager 5.1.0 software. Results: A total of 827 publications were obtained, and 3 RCTs were included after the full texts were studied. While there was no significant advantage of statin use at 3 and 6 months after intervention, the study group exhibited higher Mini-Mental State Examination (MMSE) scores than the control group one year later (p < 0.05). Also, statin use did not have a significant effect on Activities of Daily Living (ADL) scores one year after intervention (p < 0.05). The occurrence of adverse reactions in the two groups was not statistically significant (p > 0.05). Conclusion: The use of Internet cloud technology for building an Alzheimer's disease network management system simplifies the process of Alzheimer's disease diagnosis and treatment, and reduces the cost of Alzheimer's disease services.
