The clinical data of 76 children with EFE admitted from June, 1998 to December, 2009 was retrospectively analyzed. Tachypnea、 cough and cyanosis were common and all presented with heart failure. Electrocardiogram revealed sinus tachycardia 、left ventricular hyperthrophy and ST-T alterations. On chest radiograph 54 cases (54/76) had a cardiothoracic ratio ＞ 0. 65 and 33 with pneumonia.Echocardiopraphy revealed lowered left ventricular systolic function in all cases and decreased left ventricular diastolic function in 21 (21/76). 63 cases (63/76) presented with thickened and enhanced left ventricular endocardium and 11 (11/76) with thickened interventricular septals. All were treated with digitalis. 58children were improved and discharged, 10 gave up therapy and 8 died during hospitalization. 41 out of 58 improved cases were followed for 1 - 4 years, with 2. 6 years on average. Among them 28 were clinically cured, 7 deteriorated and 6 died of heart failure. Echocardiography is of diagnostic value for ERE. Systolic and diastolic function of the heart can be used to predict the outcome. Pulmonary infection is a major risk factor associated with deterioration. Long-term treatment is imperative to improve the prognosis.

Objective:To investigate the clinical value of modified acute aortic dissection risk score in the early diagnosis of acute aortic dissection (AAD).Methods:The general, clinical, and imaging data of 162 patients who complained of chest and back pain who received treatment between January 2019 and January 2021 in the Department of Emergency, The Second Hospital of Jiaxing, China were collected for this study. The included patients were divided into control (non-AAD, n = 120) and observation (AAD, n = 42) groups according to whether they were diagnosed with AAD. The indexes with statistical significance between the two groups were analyzed using multivariate logistic regression analysis. A score table was established according to the size of OR value. The modified AAD risk score was predicted using the receiver operating curve. Results:Multivariate logistic regression analysis showed that male sex, family history, sudden severe chest and back pain, bilateral blood pressure asymmetry, hypertension, abnormal ultrasound, and D-dimer level were independent risk factors for the diagnosis of AAD (statistical values = 7.84, 6.96, 7.04, 11.38, 7.12, 8.15, 15.07, 9.11, all P < 0.05). Taking the total score of 5 as the prediction standard, the specificity and sensitivity in the prediction of the occurrence of AAD were 84.94% and 95.43%, respectively. The area under the receiver operating curve regarding the modified AAD risk score was 0.909. Conclusion:The modified AAD risk score can be used to conveniently and quickly predict the occurrence of AAD and has a high predictive value. This study is highly innovative and scientific.

Objective:To understand the current status of the compliance of immunosuppressive drugs in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore the influencing factors of their compliance.Methods:This study was a cross-sectional study. Using the convenient sampling method, a total of 238 allo-HSCT patients who were followed up in the Transplant Center of Taizhou Hospital of Zhejiang Province, Zhejiang Provincial Hospital of Traditional Chinese Medicine and the First Affiliated Hospital of Wenzhou Medical University from March 2020 to February 2021 were selected as the research objects. The self-designed general information questionnaire, Basel Assessment Scale for Immunosuppressive Drug Compliance, Chinese version of Medication Belief-Specific Scale, General Self-Efficacy Scale, Perceived Social Support Scale and Family Care Index Scale were used for on-site investigation of patients. Pearson correlation analysis was used to analyze the correlation between medication compliance and medication belief, self-efficacy, social support and family care of allo-HSCT patients. Multiple linear regression analysis was used to investigate the influencing factors of immunosuppressive medication compliance in allo-HSCT patients.Results:A total of 238 questionnaires were distributed in this study, and 228 valid questionnaires were finally recovered. The medication compliance score of allo-HSCT patients was (4.80±1.18) points. And 111 patients (48.68%, 111/228) had poor medication compliance, among which the incidence of not taking medication on time was the highest, accounting for 44.30% (101/238) . Multiple linear regression analysis showed that average monthly family income, rejection, medication belief, social support and family care were the influencing factors of medication compliance ( P< 0.05) . Conclusions:The immunosuppressant medication compliance of allo-HSCT patients is at a medium and low level. Average monthly family income, rejection reaction, medication belief, social support and family care are the main factors affecting the immunosuppressant medication compliance of allo-HSCT patients. Medical staff should formulate targeted intervention measures according to the influencing factors of medication compliance to improve the immunosuppressive medication compliance of allo-HSCT patients.
