Objective To analyze the cognitive impairment and its influencing factors in patients transferred from ICU. Methods The convenience sampling method was used to investigate patients in ICU of a tertiary hospital in Fujian Province from January to August 2021. A general data questionnaire，Montreal Cognitive Assessment and Richards-Campbell Sleep Questionnaire were used to collect data to clarify the occurrence of cognitive impairment in patients transferred from ICU. Logistic regression was used to analyze the influencing factors of cognitive impairment. Results The incidence of cognitive impairment was 38.18%（84/220） in 220 patients who were transferred from ICU. Logistic regression analysis showed that age，education level，frequency of delirium and RCSQ score were independent influencing factors of cognitive impairment in patients transferred from ICU（P<0.05）. Conclusion Patients transferred from ICU have a high incidence of cognitive impairment，which is affected by a variety of factors. During clinical practice，nursing staff should pay attention to high-risk patients，and actively explore effective preventive measures to reduce the incidence of cognitive impairment.

Objective To explore the effect of illness perception interventions based on Meleis’s transitions theory on the rehabilitation of patients with functional dyspepsia. Methods 120 patients with functional dyspepsia were selected by convenient sampling in the outpatient department of gastroenterology of a tertiary A hospital in Nanchong，Sichuan Province from July to October 2021. They were divided into a control group and an experimental group with 60 cases in each group by SPSS 22.0 random number table method，and 20 cases were taken as a group to establish a Wechat group respectively. On the basis of routine outpatient care，the experimental group received illness perception interventions based on Meleis’s transitions theory；the control group received routine outpatient care and received relevant health education information through WeChat group. The duration of the intervention was 8 weeks. Data were collected by the Brief Illness Perception Questionnaire，Dyspepsia Symptoms Severity，the Affect Balance Scale，Nepean Dyspepsia Index-Short Form and so on. The cognitive level of disease，dyspepsia symptom severity，emotional balance and health-related quality of life of the 2 groups were compared before and after intervention. Results In the control group，3 cases were lost to follow-up. The cognitive level of disease and health-related quality of life of intra-group comparison and post-intervention comparison between the 2 groups were higher than those before the intervention；the severity of symptoms was lower than that before the intervention；the emotional balance was better than that before the intervention. The difference was statistically significant（P<0.05）. After the intervention，the cognitive level of disease and health-related quality of life in the experimental group were higher than those in the control group；the severity of symptoms was lower than that in the control group；the emotional balance was better than that in the control group. The difference was statistically significant（P<0.001）. Conclusion The illness perception intervention based on Meleis’s transitions theory is helpful to improve the cognitive level of disease in patients with functional dyspepsia，to reduce symptoms and negative emotions，and to improve health-related quality of life.

Objective To investigate the rehabilitation effect of swelling fluid cold therapy at different temperatures on patients with lower extremity varicose veins（LEVV） under epidural anesthesia and local swelling anesthesia. Methods 101 patients undergoing epidural anesthesia and local swelling LEVV in a tertiary A hospital in Fuzhou for vascular surgery from December 2019 to March 2021 were selected as study subjects by convenient sampling method. They were randomly divided into 3 groups according to random numbers,namely test group A with 34 cases provided with 4~9 ℃ of swelling fluid,test group B with 34 cases provided with 10~15 ℃ of swelling fluid,the control group with 33 cases provided with 18~24 ℃ of swelling fluid. The rehabilitation of surgical limb pain value,ecchymosis area,the number of hematoma occurrence and complications in the 3 days of the 3 groups were observed. Results The differences of baseline data between the 3 groups were not statistically significant（P>0.05）;the pain scores of the 2 test groups were lower than those of the control group（P<0.05）. The skin ecchymosis area on the 3rd day after the surgery in the 2 test groups was lower than it in the control group with statistically significant differences（P=0.001）. There was no significant difference in the hematoma of the 3 groups on postoperative 3rd day（P=0.278） and no adverse reactions occurred in the 3 groups. Conclusion Intraoperative cold treatment with 4~9 ℃ or 10~15 ℃ swelling fluid in patients with LEVV can reduce the pain and ecchymosis area of postoperative 3 d.
