Objective:To investigate the clinical value of 18F-NaF PET/CT coronary plague imaging in evaluating the long-term prognosis of patients with coronary artery disease (CAD). Methods:A retrospective cohort study was conducted among 54 patients (37 males and 17 females, aged (57.2±9.8) years) diagnosed with CAD from a multicenter study between September 2015 and October 2022. All patients underwent 18F-NaF PET/CT and coronary angiography (CAG) within 1 week, and the PET/CT imaging was performed at the First Hospital of Shanxi Medical University. Major adverse cardiovascular events (MACE) were followed up. ROC curves were established to obtain the optimal thresholds of SUV max and accumulated SUV max of all lesions of main coronary artery branches (S-SUV max) for predicting MACE. Cox proportional risk model and Kaplan-Meier method (log-rank test) were used to analyze the predictive value of PET parameters for MACE. Differences in metabolic parameters between 2 groups were compared by Mann-Whitney U test. Results:The median follow-up time of the 54 patients was 6.0(1.8, 6.6) years, and 13(24.1%) patients developed MACE, including 7 deaths, 5 myocardial infarction and 1 severe arrhythmia. S-SUV max in MACE group was significantly higher than that in the non-MACE group (2.64(2.08, 4.49) vs 1.83(0.95, 2.90); Z=-2.04, P=0.041). ROC curve showed that the optimal threshold of S-SUV max for MACE prediction was 2.05 (AUC=0.690). Multivariate Cox analysis showed that S-SUV max was a strong predictor of MACE (hazard ratio ( HR)=2.434(95% CI: 1.547-3.828), P<0.001). ROC curve showed that the optimal threshold of SUV max to predict MACE was 0.55 (AUC=0.659), and univariate Cox analysis showed that SUV max was a factor to predict MACE ( HR=10.192 (95% CI: 2.667-38.953), P=0.001). In 25 patients with incomplete revascularization (ICR), Kaplan-Meier analysis showed that the incidence of MACE in patients with positive 18F-NaF uptake (single medium stenosis (40%-70%) with SUV max≥0.55) was significantly higher than that in patients with negative 18F-NaF uptake (5/14 vs 0/11; χ2=6.07, P=0.014). Conclusions:18F-NaF PET/CT can be used as an independent predictor of MACE in patients with CAD and can quantitatively assess the long-term progression of moderate coronary artery stenosis. In the future, it is expected to be a new non-invasive way to guide the revascularization treatment decision of multi-vessel CAD.

【Objective】 To improve the understanding and diagnosis and treatment level of ALK negative anaplastic large cell lymphoma (ALK-ALCL) by sharing the diagnosis and treatment process of a patient with ALK-ALCL treated in Hangzhou Bay Hospital of Ningbo. 【Methods】 The clinical data and diagnosis and treatment process of the patient were retrospectively analyzed, and relevant literature was reviewed. 【Results】 The patient was a young male, with recurrent gross hematuria and right low back pain as the initial symptoms.Imaging examination indicated bladder tumor.After resection, the tumor was reduced and confirmed to be ALK-ALCL.After chemotherapy and autologous hematopoietic stem cell transplantation, the patient’s condition continued to improve.During the follow-up, no recurrence was observed. 【Conclusion】 Primary ALK-ALCL in the bladder is very rare and prone to misdiagnosis and missed diagnosis in clinical practice.The successful diagnosis and treatment experience of this patient can provide clinical reference.

Objective:To investigate the association between systemic inflammation response index (SIRI) and early neurological deterioration (END) in patients with basal ganglia hemorrhage (BGH), and then set up a prediction Nomogram model for END.Methods:The retrospective cohort study was conducted. A total of 146 patients with BGH from January 2016 to December 2018 were chosen in the Affiliated Jiangyin Hospital of Southeast University Medical College. The patients were divided into the END group ( n=34) and non-END group ( n=112), according to whether END occurred or not. The normally distributed data were presented as the mean±standard deviation ( Mean± SD), and the groups were compared using the t test. The non-normally distributed data were expressed as M ( P25, P75), and this data was analysed via the Kruskal-Wallis test. Categorical variables were described as numbers of patients (%) and compared using chi-square analysis or Fisher exact test, as appropriate. Univariate analysis and multivariate logistic regression analysis were used to identify the risk factors of END occurrence, and the relationship with SIRI. Then, each factor was scored by Nomogram method to construct the prediction model. Receiver operating characteristic curve (ROC) was drawn to assess the predictive value of SIRI and Nomogram model in the occurrence of END. Results:Univariate analysis showed that the occurrence of END was associated with hematoma volume, presence of intraventricular hemorrhage, blood glucose, lymphocyte count and SIRI ( P<0.05). Multivariate logistic regression analysis showed that hematoma volume ( P<0.001), presence of intraventricular hemorrhage ( P=0.012) and SIRI ( P=0.023) are independent risk factors for END occurrence. ROC curve analysis showed that SIRI has certain predictive value for END occurrence, and the optimal cut-off value was SIRI=5.40×10 9/L. Then these risk factors were incorporated into the Nomogram. Statistically analysis showed the model had a good predictive value, and the model combining the SIRI and other prognostic factors (AUC=0.869, 95% CI: 0.804-0.935, P<0.001) showed more favorable discriminative ability than the model without the SIRI (AUC=0.811, 95% CI: 0.734-0.889, P<0.001) and the model using the SIRI only (AUC=0.716, 95% CI: 0.622-0.810, P<0.001). Conclusion:SIRI is closely correlated with the occurrence of END in patients with BGH, and the nomogram model combining the SIRI has a more accurately predictive value, which improved the early identification and screening of END, and patient outcomes.
