Objective To evaluate the effects of percutaneous long sheath aspiration embolectomy for the treament of acute superior mesenteric artery embolism. Methods 7 cases (atrial fibrillation 4 cases; left atrium myxoma 2 cases and chronic mesenteric ischemia 1 cases) of acute measenteric artery embolism were treated with percutaneous emlolectomy using long sheath (Optimed, Germany) aspiration. Results Successful recanalizations were observed in all of the 7 cases of superior mesenteric arteries. 5 cases out of the 7 cases recovery; 1 case underwent laparotomy; 1 case died in 24 hours. Conclusions Percutaneous embolectomy using long sheath aspiration is a sample and effective method for the treatment of acute superior mesenteric artery embolism.

Objective To explore the characteristics and influencing factors of cognitive dysfunction in patients with essential tremor (ET).Methods We recruited ET patients diagnosed by the Department of Neurology of the First Affiliated Hospital of Xi`an Jiaotong University and healthy volunteers who matched the ET patients in age, gender and education level for the study.We recorded all the patients` demographic information, tremor degree, and family history based on the family tree.All the participants were tested by MMSE, MoCA, ADL, HAMD and HAMA.Results There were 88 ET patients and 63 normal subjects included in the study.According to MMSE, 31.82％ of the patients had cognitive dysfunctions, with orientation, short-term memory, calculation ability, language skills, retelling, reading comprehension, three-level command and drawing being significantly lower than those of the healthy volunteers (P<0.01);orientation was the most serious damage in cognitive function domain (K=0.624, S=0.726);three-level command was the least serious damage (K=0.274, S=0.319).According to MoCA, 86.36％ of the ET patients had cognitive dysfunction higher than normal people (P<0.05);visual space and execution, clock drawing task, naming, attention, 100-7, language skills, abstract thinking and orientation were significantly lower than normal people (P<0.01);the most serious damage in cognitive function domain was visual space and execution (K=0.651, S=0.786); the least serious damage cognitive function domain was “100-7” (K=0.406, S=0.484). Education level and age affected cognitive dysfunction (P<0.05). ADL scores showed negative correlation with cognitive function (correlation =－0.375 and －0.383, respectively; P<0.001). After the effects of anxiety and depression were excluded, onset age and tremor grading were correlated with cognitive dysfunction (P<0.05). When the above factors were put into binary Logistic regression model, education level was found to be contributed to the model (P<0.05).Conclusion Patients with ET widely suffer from cognitive impairment. Age, education level, daily life disability, age of onset, and tremor degree classification can affect cognitive dysfunction.

Objective:To explore the psychological resilience of adolescent leukemia survivors and analyze its influencing factors.Methods:From October 2018 to August 2020, convenience sampling was used to select adolescent leukemia survivors in the routine follow-up group and follow-up group for children with leukemia who stopped taking medication in Beijing Children's Hospital affiliated to Capital Medical University as the research object. The General Information Questionnaire, Resilience Scale for Chinese Adolescents, and the General Self-Efficacy Scale were used to investigate adolescent leukemia survivors. A total of 110 questionnaires were issued, and 106 valid questionnaires were returned, with the effective response rate of 96.36%.Results:Among 106 adolescent leukemia survivors, the total score of psychological resilience was (97.83±14.93) . The results of multiple linear regression analysis showed that disease risk, duration of drug withdrawal, and general self-efficacy were the influencing factors of psychological resilience in adolescent leukemia survivors, and the difference was statistically significant ( P<0.05) . Conclusions:The psychological resilience level of adolescent leukemia survivors is at an upper-middle level. Medical and nursing staff, the family and friends of adolescent leukemia survivors should pay active attention to survivors whose disease risk is medium or high risk or whose duration of drug withdrawal is less than 5 years, and provide them with a lot of support and help. At the same time, pay attention to the general self-efficacy of survivors, provide targeted self-care guidance or substantive help for the survivors to return to school and society so as to improve their psychological resilience.
