Objective:To investigate the current situation of rehabilitation motivation of middle-aged and elderly stroke patients and analyze its influencing factors, so as to provide reference for formulating targeted rehabilitation plans and intervention strategies.Methods:A convenience sampling method was used to select middle-aged and elderly stroke patients from (the First Affiliated Hospital of Shihezi University, the People's Hospital of Shihezi, and the People's Hospital of Xinjiang Uygur Autonomous Region from November 2023 to April 2024 as the study subjects. A cross-sectional survey was conducted using a general information questionnaire, the Motivation in Stroke Patients for Rehabilitation Scale, Perceived Social Support Scale, and and Apathy Evaluation Scale-Informant Version.Results:The 328 middle-aged and elderly stroke patients were ultimately included, including 223 males and 105 females, aged (63.63 ± 12.00) years. The total score of rehabilitation motivation, perceived social support and apathy symptoms of middle-aged and elderly stroke patients was ( 86.14 ± 11.28 ), (63.23 ± 6.31), (43.66 ± 4.63) points. LASSO regression screened 8 factors. Multiple linear regression analysis showed that age, education level, stroke duration, neurological deficits, activities of daily living, perceived social support and apathy symptoms were the influencing factors of rehabilitation motivation in middle-aged and elderly stroke patients ( t values were -6.52 to 7.56, all P<0.05), accounting for 72.6% of the total variation. The importance of random forest was ranked as follows: perceived social support, Activity of Daily Living, education level, stroke course, age, apathy symptoms, and neurological deficit. Conclusions:The rehabilitation motivation of middle-aged and elderly stroke patients is at a medium level. Clinical workers should focus on the rehabilitation motivation of stroke patients with insufficient social support, poor self-care ability and low education level, and regularly evaluate the level of rehabilitation motivation and the subjective initiative of rehabilitation exercise.

Objective To identify the potential categories and influencing factors of apathy in stroke patients,providing a basis for precise typing and individualized interventions by healthcare professionals.Methods Using the convenience sampling method,stroke patients from 2 tertiary hospitals in Xinjiang Uggur Automous Region were selected from November 2023 to August 2024,and were surveyed using the General Information Questionnaire,Apathy Evaluation Scale-Informant,Perceived Autonomy Scale,and Stroke Self-Efficacy Questionnaire.The latent profile analysis was used to identify potential categories of apathy,and logistic regression analysis was used to explore the differences in the characteristics of patients in different categories.Results The apathy symptoms of 521 stroke patients could be divided into 3 potential categories:mild apathy group(23.6％),moderate apathy-low interest-low behavioral group(46.5％),and heavy apathy-low interest-low cognitive group(29.9％).Logistic regression showed that age 45～＜60 years,duration of the disease＜6 months,and high rehabilitation self-efficacy were the common protective factors of the moderate apathy-low interest-low behavioral group and the heavy apathy-low interest-low cognitive group.The dependence on activities of daily living was a risk factor for the moderate apathy-low interest-low behavioral group,and high perception of autonomy was a protective factor for the heavy apathy-low interest-low cognitive group.Conclusion Apathy symptoms in stroke patients are characterized by distinct categories,which are influenced by age,stroke duration,ADL,rehabilitation self-efficacy,and perception of autonomy.Healthcare professionals should adopt effective strategies to precisely intervene based on different potential categories of protective factors and risk factors to alleviate their apathy.

Objective To develop a novel protective ventilator circuit component and to verify its performance by water seal and anti-splash experiments.Methods A novel protective ventilator circuit component had a design scheme with the multifunctional joint,and consisted of a tee connection tube,an isolation sleeve and a stop sleeve,of which,the tee connection tube was made of polyethylene polymer material and the others were made of silicone material.The tee connection tube had a T-shaped structure with two standard connection ports,which was composed of an adapter,a sealing cap,a plug and a sealing ring;the isolation sleeve was in the shape of a cylinder with a raised bottom,which was inserted into the adapter;the stop sleeve was located in the isolation sleeve,with an inverted frustum of a cone at the bottom and a rounded hole in the middle of the inverted frustum.An open ventilator circuit tube was involved in the performance verification of the circuit component developed.In the water seal experiment,sputum aspiration was simulated and the heights of the liquid level drop in the L-shaped tubes were compared after sputum aspiration.In the anti-splash experiment,the infection rates on the surfaces of the sterile hole towels and gloves were calculated.Results Water seal experiment showed after sputum aspiration the open ventilator circuit tube had the liquid level at the L-shaped tube higher significantly than that of the circuit component;the anti-splash experiment indicated sputum aspiration resulted in the occurance of the splashing out of the secretion and 77.5%infection rate by the open ventilator circuit tube,while no splashing out and 0%infection rate by the circuit component developed.Conclusion The novel protective ventilator circuit component behaves well in sealing and anti-splashing,and thus is worthy of clinical application for sputum aspiration.[Chinese Medical Equipment Journal,2025,46(4):113-117]

Objective:To analyze the current policy design of outpatient benefit policies for patients with hypertension and diabetes(H&D)in urban and rural residents in China,and to provide references for optimizing the outpatient benefit mechanism for patients with H&D.Methods:A questionnaire survey was conducted to collect data on the basic features of General Outpatient Benefit(GOB),Outpatient Medication Guarantee Mechanisms for Hypertension and Diabetes(OMGM-H&D)and Outpatient Benefit for Patient with Chronic and Special Diseases(OB-C&S),focusing on deductibles,policy reimbursement ratios,and maximum payment limits.Descriptive statistical analysis was performed on the data.Results:A total of 334 regions were surveyed,of which 253 regions(75.34％)had implemented all three policies.Regional analysis revealed significant differences(P<0.001)in reimbursement ratios for GOB and the OMGM-H&D between the eastern,central,and western regions,with the western region having notably higher ratios than the eastern and central regions.However,no significant difference (P>0.05) was observed in the reimbursement ratios for OB-C&S across regions. Regarding deductibles,no significant regional difference (P>0.05) was found for GOB,but significant differences (P<0.05) existed for the OMGM-H&D and OB-C&S. Additionally,the annual maximum payment limits for all three policies showed significant regional variations (P<0.001). Conclusions:The outpatient benefits policy for patients with H&D have achieved full coverage nationwide among urban and rural residents in China,but regional equity in benefit levels requires improvement. It is recommended to strengthen data feedback mechanisms and promote provincial-level pooling of medical insurance.
