Objective:To evaluate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of solid intraductal papilloma (sIDP) of breast by comparing with fibronenoma of breast (FA).Methods:The CEUS data of 62 cases of sIDP patients and 94 cases of FA patients that confirmed by pathology in the First Affiliated Hospital of Soochow University from October 2016 to January 2021 were retrospectively analyzed. The patients were divided into sIDP group and FA group according to the pathological results. The enhancement speed, enhancement degree, enhancement uniformity, whether the edge after enhancement was polished, whether the enhancement range was enlarged, whether there was a ring unenhanced area in the inner edge of the lesion and whether the inner edge of the unenhanced area was polished were observed in the two groups. SonoLiver software was used to perform offline analysis of the dynamic process of CEUS in the two groups respectively, the enhancement sequence diagram of the lesions was obtained. The pathological result was taken as the gold standard, univariate analysis was applied, and the parameters with statistical significance between the two groups were included in multivariate Logistic regression analysis to establish a differential diagnosis model. The diagnostic efficiency of sIDP was analyzed by ROC curve and diagnostic model.Results:Compared with the FA group, CEUS in the sIDP group mostly showed fast forward, high enhancement, and the enhancement sequence was mostly centrifugal. After CEUS, the lesion edges in the sIDP group were mostly accompanied by unenhanced areas and the inner edges of the unenhanced areas were not intact, and the differences between the two groups were statistically significant (all P<0.05). Binary Logistic regression showed that age, enhancement degree and enhancement order were independent risk factors for sIDP diagnosis. The ROC curve showed that the area under the ROC curve of age, enhancement degree and enhancement sequence combined for the diagnosis of sIDP was 0.874 (95% CI=0.812-0.922), the accuracy was 76.9%, the sensitivity was 67.7%, the specificity was 83.0%, the positive predictive value was 72.4%, and the negative predictive value was 79.6%. Conclusions:There are significant differences in age, enhancement degree and enhancement sequence between sIDP and FA patients. The three-parameter combination can improve the diagnostic efficiency of sIDP.

Patients with gastric cancer are at high risk for venous thromboembolism(VTE)and bleeding,and patients who develop VTE are often associated with poor outcomes,making it clinically challenging to identify and manage the risk of thrombosis in patients with gastric cancer.Risk factors for VTE in gastric cancer patients include age,obesity,surgery,chemotherapy,etc.It is essential to identify high-risk patients and adopt aggressive prevention strategies.The main strategy to prevent and treat VTE is the use of anticoagulant drugs.This article discusses guidelines and recent studies for the prevention and treatment of VTE in patients with gastric cancer to help clinicians make individualized decisions for their patients and maximize clinical outcomes for their patients.

Patients with primary membranous nephropathy(PMN)tend to develop thrombosis,especially in the early phase of the disease.The pathogenesis of thrombosis is multifactorial,with hypoalbuminemia being widely regarded as an inde-pendent risk factor.Other factors include proteinuria,M-type phospholipase A2 receptor antibody,and D-dimer.Although prophy-lactic anticoagulation therapy is frequently used in clinical practice to prevent thrombosis in PMN patients,there are still many un-resolved issues regarding the optimal prevention of thrombosis in this condition.The timing of prophylactic anticoagulation,the threshold of serum albumin level,and the choice of treatment regimen are still lacking consensus.This article reviewed the relevant literature on these topics,aiming to establish a standard for thrombosis prevention and treatment for this population in the future and provide guidance for clinical practice.

OBJECTIVE: To analyze the blood free carnitine (C0) level and SLC22A5 gene variants in 17 neonates with Primary carnitine deficiency (PCD) and to determine its incidence in local area and explore the correlation between C0 level and genotype. METHODS: 148 043 newborns born in 9 counties (cities and districts) of Ningde city from September 2016 to June 2021 were selected as study subjects. Blood free carnitine and acyl carnitine of 148 043 neonates were analyzed. Variants of the SLC22A5 gene were screened in those with blood C0 < 10 µmol/L, or C0 between 10 ∼ 15 µmol/L. Correlation between the free carnitine level and genetic variants was analyzed. RESULTS: In total 17 neonates were diagnosed with PCD, which yielded a prevalence of 1/8 707 in the region. Twelve variants of the SLC22A5 gene were identified, with the common ones including c.760C>T, c.1400C>G and c.51C>G. Compared with those carrying other variants of the gene, children carrying the c.760C>T variant had significantly lower C0 values (P < 0.01). CONCLUSION The prevalence of PCD is relatively high in Ningde area, and intervention measures should be taken to prevent and control the disease. The c. 760C>T variant is associated with lower level of C0, which can provide a clue for the diagnosis.
