SUMMARY OBJECTIVE: The aim of this study was to investigate the quality of life for patients with in-stent restenosis after interventional therapy of peripheral artery disease and the influencing factors. METHODS: A total of 72 in-stent restenosis patients after interventional therapy of peripheral artery disease were enrolled, whose general data were obtained. SF-12 scale was used to evaluate the quality of life. Tilburg Frailty Scale was used to assess senile debilitation. Pittsburgh Quality Index Scale was used to evaluate sleep quality. Activity of Daily Living Scale was used to evaluate the self-care ability. The general data and in-stent restenosis-related indicators were compared between patients with low and high quality of life, respectively. Multivariate regression analysis was made on the factors affecting quality of life. RESULTS: The average total quality of life score of 72 patients was 74.06±19.26 points. The gender, Fontaine stage and smoking, Activity of Daily Living Scale score, painless walking distance, senile debilitation score, sleep quality score, white blood cells, and C-reactive protein had significant differences between the two groups, respectively (p<0.05). Multivariate regression analysis showed that the female gender, low Fontaine stage (OR=0.186), low senile debilitation score (OR=0.492), and high sleep quality score (OR=0.633) were the protective factors for high quality of life (all p<0.05), and the low Activity of Daily Living score (OR=1.282) was the risk factor for high quality of life (p<0.05). CONCLUSION: Quality of life of in-stent restenosis patients after interventional therapy of peripheral artery disease is low. Gender, Fontaine stage, senile debilitation, sleep quality, and Activity of Daily Living score are the influencing factors of quality of life for in-stent restenosis patients.

Abstract To analyze the effect of AI deep learning techniques on understanding possible complications and improving clinical nursing quality of patients with coronary heart disease. The clinical data of 182 patients with coronary heart disease who received treatment were collected, among which 80 patients received routine nursing management only during hospitalization, set as the control group; AI deep learning techniques were applied to the other 102 patients During treatment and nursing, the incidence of related complications in the control group was higher than that in the observation group, and the average hospitalization time of the patients was longer than that in the observation group. In the observation group, AI deep learning techniques were applied to predict the incidence of complications of coronary heart disease in 14 patients, with an accuracy rate of 87.50% (14/16) and an error rate of 12.50% (2/16). Both the clinical nursing quality and patients’ satisfaction score of the observation group were higher than those of the control group, and the overall nursing satisfaction rate of the patients was higher. Applied in prediction of possible complications of hospitalized patients with coronary heart disease, AI deep learning techniques were of high accuracy rate.

Abstract To explore the improvement value and treatment safety of neurological rehabilitation strengthening training on upper-limb functions of cerebrovascular patients. A total of 80 patients with cerebrovascular hemiplegia were divided into two groups. The 40 patients in the regular group were instructed to carry out regular rehabilitation training for 20 min/day, lasting for 5d/week; another 40 patients in the strengthening group were instructed to carry out neurological rehabilitation strengthening training on the basis of regular training. Before the intervention, there was no significant difference in fma-ue, ARAT, MBI scores and EDV, RI, PSV of carotid and vertebral arteries between the two groups (P > 0.05); after treatment, fma-ue, ARAT, MBI, EDV, PSV of the study group were higher than those of the control group, RI was less than that of the control group, the differences were statistically significant (P<0.05), after the intervention, the number of patients with grade IV ~ VI in the study group was more than that of the control group, the difference was statistically significant (P<0.05). The application of neurological rehabilitation strengthening training might improve the upper-limb motor functions of patients with cerebrovascular hemiplegia and promote the rehabilitation of limb nerve functions.
