ObjectiveTo observe the effect of brain-computer interface (BCI) training based on motor imagery on hand function in hemiplegic patients with subacute stroke. MethodsFrom June, 2020 to December, 2021, 40 patients with hemiplegia in subacute stroke from Department of Rehabilitation Medicine, Fifth Affiliated Hospital of Zhengzhou University were divided into control group (n = 20) and experimental group (n = 20) using random number table. Both groups accepted medication and routine comprehensive rehabilitation, while the control group accepted hand rehabilitation robot training, and the experimental group accepted the robot training using motor imagery-based BCI, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index, modified Ashworth scale, and measured integrated electromyogram of the superficial finger flexors, finger extensors and short thumb extensors of the affected forearm during maximum isometric voluntary contraction with surface electromyography. ResultsTwo patients in the control group and one in the experimental group dropped off. All the indexes improved in both groups after treatment (t > 2.322, Z > 2.631, P < 0.05), and they were better in the experimental group than in the control group (t > 2.227, Z > 2.078, P < 0.05), except the FMA-UE score of wrist. ConclusionMotor imagery-based BCI training is more effective on hand function and activities of daily living in hemiplegic patients with subacute stroke.

Objective To observe the effect of iliopsoas tensile vibration training on the walking ability of stroke survivors.Methods Thirty stroke survivors were randomly divided into an observation group and a control group,each of 15.Both groups were given traditional rehabilitation treatment,while the observation group was additionally provided with iliopsoas tensile vibration training.Both groups were evaluated in terms of the root mean square (RMS) of iliopsoas,active range of motion (A-ROM) of the hip joint,the kinematic parameters of gait and Berg balance scale (BBS) scores before and after the 4-week treatment.Results Before the treatment there were no significant differences between the two groups in any of the measurements.After the treatment improvement in all of the measurements was observed in both groups,with the average RMS iliopsoas,A-ROM,step length,step velocity and BBS score of the observation group significantly better than those of the control group.Conclusions Tensile vibration training of the iliopsoas can significantly improve the muscle excitability of the affected iliopsoas in stroke survivors,and improve their balance and walking ability.

Objective: To find out the characteristics and regularity trend of influenza activity according to the analyses of influenza surveillance data in Yangzhou from 2012 to 2017, and to provide scientific supports for predicting and controlling the pandemic outbreak of influenza effectively. Methods: The influenza samples were collected from Northern Jiangsu People′s Hospital, Yangzhou First People's Hospital and Gaoyou People’s Hospital, using fluorescent RT-PCR method to detect influenza virus nucleic acid and classifying influenza virus subtypes. Finally, the surveillance data from January, 2012 to December, 2017 of influenza like illness (ILI) cases of Yangzhou were analyzed. Results: Totally 18 083 throat swabs of ILI specimens were collected from 2012—2017 in Yangzhou, 1 983 samples were positive (10.97%), the difference in positive rates of adjacent years was statistically significant (χ²=167.93, P<0.001). In Yangzhou city, influenza virus kept activative in whole year. The influenza epidemic season was winter-spring and summer, accounting for 83.61% of all positive cases, with type A influenza prevalent throughout all year and type B influenza mainly prevalent in spring and winter, each subtype showed alternating prevalence. The influenza virus infection occurred in every age group. The highest positive rate was 16.33% in the age group of 10-19 years and the lowest was 8.52% in the age group of 20-29 years among all detected age groups. Conclusions From 2012 to 2017, the epidemic of influenza in Yangzhou was obviously seasonal and all the subtypes of influenza were in prevalent status alternately. The high-risk groups of Influenza were infants and teenagers who under the age of 19 years. So a long-term influenza surveillance is much needed for the early warning and forecasting the spread of influenza.
