Comparative Analysis of Three Massive Medical Image Storage Technologies / 中国医疗器械杂志

Nowadays, the massive medical data have already influenced the information construction in medical institutes, so it is not enough to solely rely on traditional local storage system to solve the problems like the read/write speed, visualization, and economy brought about by the massive data. Furthermore, various medical cloud services have been developed at home and abroad that patients' medical data can be shared through all medical institutes on the cloud, which makes a higher demand on the transmission speed of the medical data. This article analyzes from multiple aspects like high availability and costs by performing a medical image transmission speed test on the three mainstream storage technologies to provide an optional storage system for future medical image big data in the access process. The experimental result shows that it can be found that in the process of accessing medical image big data, the access speed and performance of object storage system is better than those of the existing local storage systems. However, with comprehensive consideration, it is recommended that the distributed file storage system like HDFS be the first choice for the storage system of the medical images.

Contrastive analysis of timed up and go test, maximum walking speed test on evaluating stroke patients' function / 中国康复医学杂志

Objective:To explore the efficiency of timed up and go test (TUGT) and maximum walking speed test (MWST) on evaluating stroke patients' motor function.Method:Fifty stroke patients were assessed with TUGT,MWST,Berg balance scale (BBS),Barthel Index (BI) and Fugl-meyer assessment.The levels of association among five methods were examined with Pearson correlation coefficients.The predictive efficiency was analyzed by using receiver operating characteristic curve (ROC).Result:The significant negative correlation was shown between TUG and BBS,BI and FMA score (P ＜ 0.05) and the same significant negative correlation was shown between MWST and BBS,BI and FMA score (P＜0.05).The Pearson correlation coefficients of TUG was higher than the MWST's.The area under the ROC curve for the TUG was significantly higher than that of the MWST.Conclusion:The TUG is closely correlated with the balance ability,moto function and active of daily living in stroke patients.The TUG could serve as a screening tool for detection of individuals with stroke.

The timed up and go test and maximum walking speed test for evaluating the walking ability of stroke patients / 中华物理医学与康复杂志

Objective To explore the effectiveness of the timed up and go test (TUGT) and the maximum walking speed test (MWST) in evaluating stroke patients' motor function.Methods Twenty-two stroke patients were assessed using the TUGT and MWST,and the temporal-spatial parameters of their gait were also assessed.The correlations among the TUGT times,walking speed and the gait parameters were quantified using Pearson correlation coefficients.Results The TUGT time was (18.57±7.41) s,significantly correlated with step length and velocity (P＜0.05).Walking speed showed a significant positive correlation with step length,velocity and step length (P＜ 0.05).The TUGT times were negatively correlated with walking speed (r=-0.712,P=0.000).Conclusion The MWST and TUGT both can assess stroke patients' motor function effectively.
