Objective To explore the effect of occupational skills relearning programme on hemiplegic arm motor function and ac-tivities of daily living(ADL)in stroke patients. Methods From February,2022 to August,2023,74 stroke patients in Guangdong Work Injury Rehabilitation Hospital were enrolled and randomly divided into control group(n=37)and experimental group(n=37).The control group received conventional rehabilitation training,and the experimental group received additional occupational skills relearning programme,for three weeks.They were assessed with Fugl-Meyer Assessment-Upper Extremi-ties(FMA-UE),Functional Test for the Hemiplegic Upper Extremity-Hong Kong(FTHUE-HK),Motor Activity Log(MAL)-amount of use(AOU)and MAL-quality of movement(QOM),modified Barthel Index(MBI),and Stroke Impact Scale(SIS)-Hand and SIS-ADL before and after treatment. Results The scores in all assessments improved significantly in both groups(|t|>3.597,P<0.05)after treatment,while the scores of FMA-UE,FTHUE-HK,MAL-AOU,MAL-QOM were higher in the experimental group than in the control group(|t|>2.352,P<0.05). Conclusion Occupational skills relearning programme could promote the recovery of hemiplegic arm motor and activity,and facilitate the use of the hemiplegic arm in daily life in stroke patients.

Objective To investigate the progress of two-dimensional echocardiographic parameters in patients with different severity of aortic stenosis.Methods A retrospective analysis was per-formed on 96 patients diagnosed with aortic stenosis with at least 2 times of transthoracic echo-cardiography(interval ≥1 year)in Department of Cardiology,Fourth Medical Center of Chinese PLA General Hospital from March 2017 to December 2023.According to aortic stenosis severity,they were divided into a mild group(72 cases),a moderate group(14 cases)and a severe group(10 cases).Peak pressure gradient(PPG)across aortic valve,Vmax,mean aortic valve pressure gradient(ΔPm),pulmonary artery systolic pressure(PASP)were collected,and the changes and annual progress of these echocardiographic parameters at baseline and before and after follow-up were analyzed.Results The values of IVST,LVPWT,Vmax,aortic valve PPG and ΔPm were sig-nificantly increased in the mild,moderate and severe stenosis groups in turn(P＜0.05,P＜0.01).The values of Vmax,PPG and ΔPm were significantly lower in the mild stenosis group than the moderate and severe stenosis groups,and the LVPWT value was obviously lower in the mild ste-nosis group than the severe stenosis group(P＜0.05).The aortic valve PPG and ΔPm values at follow-up were significantly higher than those before the follow-up in the three stenosis groups(P＜0.05,P＜0.01).After follow-up,the Vmax values in mild and moderate stenosis groups were notably higher than before(P＜0.01).The PASP value at follow-up was significantly higher than before in the severe stenosis group(P＜0.05).The annual progression rate of Vmax,PASP,LVEF were gradually increased in the mild,moderate,and severe stenosis groups(P＞0.05).The annual progression rate of ΔPm was gradually increased in the three groups in turn(2.30±1.77 mm Hg/year vs 2.40±1.18 mm Hg/year vs 6.08±1.70 mm Hg/year,P＜0.05).Conclusion As the severity of baseline aortic stenosis increases,obvious changes are observed in cardiac structure and function.Before and after follow-up,the serious the aortic stenosis severity is,the faster the annual progression rates of Vmax,PPG,LVEF and PASP are.
