Objective To investigate the plasma levels of signal peptide-CUB epidermal growth fac-tor domain inclusion protein-1(SCUBE-1),asymmetric dimethylarginine(ADMA)and insulin-like growth factor binding protein-2(IGFBP-2)in elderly patients with acute pulmonary embol-ism(PE)and their relationship with risk stratification and poor prognosis.Methods A total of 117 elderly patients with acute PE admitted to our hospital from January 2022 to December 2023 were retrospectively enrolled in this study.With risk stratification,there were 41 patients of high-risk,46 of medium-risk and 30 of low-risk.According to their clinical outcomes,they were divided into good prognosis group(85 cases)and bad prognosis group(32 cases).The plasma levels of SCUBE-1,ADMA,and IGFBP-2 were measured using ELISA.Multivariate logistic regression analysis was applied to identify the risk factors for poor prognosis,and ROC curves were drawn to analyze the predictive value of plasma levels of SCUBE-1,ADM A and IGFBP-2 for poor prognosis of these patients.Results The levels of cTnI,BNP,D-dimer,SCUBE-1,ADMA and IGFBP-2 were significantly higher in the poor prognosis group than the good prognosis group(0.95±0.28μg/L vs 0.30±0.08 μg/L,2017.62±308.15 μg/L vs 538.14±102.73 μg/L,5.24±1.13 μg/L vs 1.63±0.27 μg/L,22.50±10.14 μg/L vs 9.25±4.36 μg/L,2.01±0.72 μmol/L vs 0.61±0.17μmol/L,468.16±90.51 μg/L vs 155.27±30.74 μg/L,P＜0.01).The high-risk patients had high-er plasma levels of SCUBE-1,ADMA and IGFBP-2 than the medium-and low-risk patients in or-der(all P＜0.01).Multivariate logistic regression analysis showed that elevated levels of cTnI,BNP,D-dimer,SCUBE-1,ADMA and IGFBP-2 were risk factors for death in acute PE patients(P＜0.05).ROC curve analysis indicated that the AUC value of SCUBE-1,ADMA and IGFBP-2 combined together in predicting death for acute PE patients was the highest(0.927,95％CI:0.864-0.993),with an accuracy of 93.1％.The plasma levels of SCUBE-1,ADMA and IGFBP-2 were positively correlated with the levels of cTnI,BNP and D-dimer in the elderly patients(P＜0.01).Conclusion For the elderly patients with acute PE,elevated plasma levels of SCUBE-1,ADMA and IGFBP-2 are associated with risk stratification and poor prognosis.Combination of these three indicators has certain predictive value for poor prognosis in the patients.

BackgroundPsychological capital has a significant impact on individual post-traumatic growth and well-being. However， there is limited research on the psychological capital and its related factors among parents of children with leukemia. ObjectiveTo explore the psychological capital status of parents of children with leukemia and analyze its influencing factors， in order to provide references for formulating intervention strategies to improve the psychological capital among these parents. MethodsFrom March 2021 to April 2022， 143 parents of children diagnosed with leukemia from the Department of Pediatrics at the First Affiliated Hospital of Xinjiang Medical University was selected. The general demographic information questionnaire， Positive Psychological Capital Questionnaire （PPQ）， Chinese-Posttraumatic Growth Inventory （C-PTGI） and Index of Well-being Scale （IWB） were used to investigate the participants. Multiple linear regression analysis was used to analyze the influencing factors of psychological capital. ResultsThe PPQ total score for parents of children with leukemia was （113.48±15.80）. The PPQ total score showed positive correlations with the scores of C-PTGI and IWB （r=0.727， 0.598， P<0.01）. The course of children's illness （β=0.136， P=0.017）， parental education level （β=0.139， P=0.012） and C-PTGI score （β=0.622， P<0.01） were influencing factors of psychological capital among these parents， collectively explaining 57.6% of the total variability. ConclusionThe level of positive psychological capital among parents of children with leukemia warrants improvement. Factors including course of the children's illness， parental education level and post-traumatic growth significantly impacted their psychological capital.［Funded by Innovation and Entrepreneurship Project for Graduate Students of Xinjiang Medical University （number， CXCY2022047）］

Abstract Alzheimer's disease (AD) is a neurodegenerative disease characterized by deposition of β-amyloid (Aβ). Liver X receptors (LXRs), a member of the nuclear receptor transcription factor superfamily, are widely expressed in brain, which may be involved in the development and progression of AD. Based on the international and national publications pertaining to the association between LXRs and AD from 2010 to 2022, this review summarizes the advances on the involvement of LXRs in the regulation of cholesterol metabolism, inflammatory response and synapse formation in the pathogenesis of AD was reviewed, so as to provide insights into the prevention and treatment of AD.

【Objective:】 To explore the disease communication between cancer children and their parents from the perspective of their parents. 【Methods:】 Using qualitative description method and semi-structured interview, 16 parents from the pediatric oncology department of a tertiary A hospital were collected. Colaizzi 7-step method was used to analyze the interview data and summarize the theme. 【Results:】 Four themes were summarized, including perception of the psychological changes of children after illness, changes in the future planning of children, different attitude towards informing children’s diseases, different opinions on children’s participation in medical decision-making. 【Conclusions:】 The awareness of disease communication and medical decision-making in cancer families is insufficient. It is difficult for parents to communicate actively and effectively with their cancer children, and the children’s families are unable to make clear plans for the children’s future. Therefore, it is necessary to construct a theoretical system of disease communication and medical shared decision-making from the perspective of Chinese familism, and strengthen the promotion of scientific communication methods.

Objective:To evaluate the static symmetry in patients with early facial paralysis after masseteric-to-facial nerve transfer combined with fascia lata graft.Methods:Clinical data of paralyzed patients who treated with masseteric-to-facial nerve transfer combined with fascia lata graft in Shanghai Jiao Tong University School of Medicine Affiliated Ninth People’s Hospital from January 2016 to December 2018 were retrospectively analyzed. Patients were divided into two groups according to the degree of preoperative oral commissure dropping: slight asymmetry (Scale Ⅱ, Group A) and severe asymmetry (Scale Ⅲ, Group B). Facial muscle contraction was evaluated by Terzis Facial Grading System to evaluate smile function, which was divided into Score Ⅰ, Ⅱ, Ⅲ, Ⅳ and Ⅴ. The higher the score, the better the facial muscle contraction and the better the dynamic symmetry during preoperatively and one year postoperatively. The static symmetry of oral commissure was evaluated by Symmetry Scale of Oral Commissure to evaluate symmetry at rest, which was divided into Scale Ⅰ, Ⅱ, Ⅲ and Ⅳ, the higher the scale, the worse the static symmetry. Face-gram software was adopted to measure bilateral vertical differences(D 1) or horizontal differences(D 2) in the oral commissure position of the patients with facial paralysis for evaluating the postoperative static symmetry objectively. Statistical analyses were performed with SPSS version 26.0. Numeration data were analyzed by chi-square test. Intragroup quantitative data was analyzed by paired t-test and intergroup quantitative data was analyzed by two-sample t-test. The significance level was set at 0.05. Results:A total of 58 patients were included, including 30 patients in group A [male 12, female 18, age (43.5 ±8.1) years], and 28 patients in group B[male 12, female 16, age (40.6 ±9.6) years]. There was no significant difference in sex, age at surgery, paralyzed side and denervation time between groups ( P>0.05). The patients were scored Ⅰ on Terzis’ smile functional evaluation scale preoperatively. The score of smile function in postoperative percentage in all patients was improved to Score Ⅲ (Group A, 9/30, 30.0%; Group B, 10/28, 35.7%) or Score Ⅳ (Group A, 21/30, 70.0%; Group B, 18/28, 64.3%), according to the Terzis Facial Grading System. There was no significant difference in the improvement of smile function between groups ( P>0.05). In Group A, 73.3% patients had postoperative improvement in static symmetry (Scale Ⅱ to Scale Ⅰ, 22/30) and 26.7% patients were still Scale Ⅱ according to Symmetry Scale of Oral Commissure to evaluate symmetry at rest. In Group B, 39.3% of patients achieved static symmetry effect (Scale Ⅲ to Scale Ⅰ, 11/28), 42.9% patients had postoperative improvement (Scale Ⅲ to Scale Ⅱ, 12/28) and 17.8%(5/28) of them were still Scale Ⅲ. The proportion of achieving static symmetry effect (Scale Ⅰ) in Group A was higher than that in Group B ( P<0.01). D 1 values of one-year postoperation were smaller than that of preoperation [Group A: (5.27 ±0.74) mm vs. (2.24 ±0.57) mm; Group B: (8.22 ±1.37) mm vs. (4.42 ±0.95) mm, P<0.01]. Similarly, D 2 values of one-year postoperation were smaller than that of preoperation [Group A: (6.11 ±1.18) mm vs. (2.98±1.13) mm; Group B: (8.84 ±2.16) mm vs. (5.24 ±1.85) mm, P<0.01]. There were significant differences between groups in preoperative comparison and one-year postoperative comparison( P<0.01). Conclusions:Masseteric-to-facial nerve transfer combined with fascia lata graft achieved dynamic and static symmetry in patients with different levels of asymmetry. The postoperative static symmetry effect at rest may be influenced by the different levels of oral commissure asymmetry preoperatively.

There were significant differences between groups in preoperative comparison and one-year postoperative comparison( P<0.01). Conclusions:Masseteric-to-facial nerve transfer combined with fascia lata graft achieved dynamic and static symmetry in patients with different levels of asymmetry. The postoperative static symmetry effect at rest may be influenced by the different levels of oral commissure asymmetry preoperatively.

Objective:To investigate the level of nurses' turnover intention in ClassⅢ Grade A hospitals, and explore the correlation and interaction between nurses' psychological capital, social support, and turnover intention.Methods:Totally 2 600 nurses from 3 ClassⅢ Grade A hospitals in Urumqi were selected for questionnaire survey with the general demographic information questionnaire, Psychological Capital Questionnaire (PCQ) , Social Support Scale (SSS) , and Turnover Intention Scale (TIS) between January and August 2018. Totally 2 345 valid questionnaires were recovered. The structural equation model was used to analyze the mediating effect of nurses' psychological capital in the path of social support and turnover intention.Results:The total scores of 2 345 nurses' psychological capital, social support, and turnover intention were (86.30±8.99) , (41.17±7.68) , and (14.39±3.63) , respectively. The correlation analysis showed that nurses' social support and psychological capital scores were negatively correlated with their turnover intention score ( P<0.05) . The structural equation model analysis revealed that psychological capital had a mediating effect between social support and turnover intention, and the mediating effect accounted for 38.2% of the total effect. Conclusions:Nurses in Class Ⅲ Grade A hospitals have a high level of turnover intention. Nursing managers may reduce nurses' turnover intention by improving their social support and psychological capital.

Objective: This study was to investigate the effects of MEHP on isolated rat heart and explore its mechanism. Methods: The experiments were performed with Langendorff-perfused rat heart with a Langendorff apparatus. 35 SD rats were used in the experiment and there were 5 rats per group. MEHP at doses of 3.125, 6.250, 12.500 and 25.000 μmol/L were given to the hearts for 25 minutes. Effects of NAC at concentration of 5 mmol/L were evaluated by co-treatment with 12.500 or 25.000 μmol/L MEHP. Data was collected per 5 minutes for 25 minutes. The heart rate, LVDP, LVEDP, dp/dtmax, and dp/dtmin were measured and analyzed using a PL3508 Data Acquisition and Analysis System. 200 waves at least were required each time. LDH contents in heart lavage fluid were determined by photometric assays using the automated biochemical analyzer. A section of the heart tissue was used for histopathological examination. DCFH-DA method was used to detect the levels of reactive oxygen species in different groups of heart tissues. Results: There was a concentration dependent decrease of heart rate (P<0.05) . At concentrations of 6.250, 12.500 and 25.000 μmol/L, MEHP significantly decreased the LVDP, dp/dtmax and dp/dtmin (P<0.05) , and this decrease is more pronounced with perfusion time. As the MEHP was given up to 6.250, 12.500 and 25.000 μmol/L, a statistical significance was found in the increase of LVEDP (P<0.05) . For dp/dtmin, a significant increase was observed at the concentration of 3.125 μmol/L when perfused with 10 and 15 min (P<0.05) , but this increase disappeared over time. LDH in cardiac perfusate increased as the MEHP given a higher concentration (P<0.05) . Compared with the control group, Histopathological analysis showed edema of myocardial tissue and cells, and inflammatory cells infiltration and myocardial cells necrosis were obvious in the MEHP perfusion groups. Myocardial ROS levels of the four MEHP treatment groups were all significantly higher than that of control group (P<0.05) . These heart damage induced by MEHP could be attenuated by NAC in different degrees. Conclusion MEHP can induce damage to myocardial tissue of isolated rat heart and one possible mechanism is the oxidative stress
