Comparison of clinical data between hepatocellular adenoma group and focal nodular hyperplasia group
Source publication
BACKGROUND
Focal nodular hyperplasia (FNH) has very low potential risk, and a tendency to spontaneously resolve. Hepatocellular adenoma (HCA) has a certain malignant tendency, and its prognosis is significantly different from FNH. Accurate identification of HCA and FNH is critical for clinical treatment.
AIM
To analyze the value of multi-parameter...

Background
Hepatocellular adenoma (HCA) subtypes are considered as risk factors for malignant transformation; thus, an accurate diagnosis is important. We report a case of resected HCA previously diagnosed as unclassified HCA using immunohistochemistry, subsequently discovered to harbor a mutation in exon 3 of the beta (β)-catenin gene using deoxyr...
Hepatocellular adenomas are uncommon benign epithelial tumors of the liver that are associated with several risk factors such as anabolic androgens and oral contraceptive pills. They may present as incidental findings, with abdominal pain or hemorrhage. This case report details the presentation and management of a life-threatening hepatocellular ad...
Liver tumors in children can be benign or malignant. Although several clinical factors are important in the evaluation of these lesions, MRI is particularly important for lesion characterization and tumor staging. In children, use of a hepatobiliary contrast agent is recommended to evaluate a known or suspected liver lesion. In this review, we disc...
Hepatoblastoma (HB) is a rare tumor, but it is the most common primary liver malignancy in children and comprised of approximately 1% of all pediatric malignancies. Mostly, this tumor is sporadic in nature but can show a syndrome association. Upregulation in Wnt/β-catenin pathway can be there in 70–80% cases of HB. Most often present as abdominal m...
The patient was an 18-year-old man with a high γ-GTP level and a huge tumor found in the lateral segment of the liver on abdominal US. He was admitted to our hospital. Dynamic CT showed a tumor of 18 cm in diameter in the left lateral segment. The tumor was strongly enhanced in the arterial phase and showed prolonged enhancement in the delayed phas...

Objective:
To investigate the clinical application values of electrocardiogram (ECG) combined with ultrasound cardiogram (UCG) in the differential diagnosis of cardiomyopathy.
Methods:
A total of 120 patients with cardiomyopathy who were admitted to our hospital were randomly divided into the dilated cardiomyopathy (DCM) group (60 cases) and the ischemic cardiomyopathy (ICM) group (60 cases). Both groups were examined using ECG combined with UCG. The ultrasonic values (aorta, LADI, LVDd, LVESD, RVID, SV, LVEF, LVET, EPSS, E/A, RV6, RV6/RMAX), morphological changes (thin and round left ventricular apex, spherical left ventricle, arch-shaped left ventricle, segmental wall-motion abnormalities (SWMAs), diffuse wall motion abnormalities (DWMAs), paradoxical ventricular wall motion) and heart valve regurgitation (aortic valve, mitral valve, tricuspid valve, pulmonary valve) were compared and analyzed.
Results:
The degree of chamber enlargement in the DCM group was remarkably higher than that in the ICM group, but the degree of LVEF and aortic enlargement were significantly lower than those in the ICM group (P<0.05). The detection rates of spherical left ventricle and DWMAs in the DCM group were 60.00% and 100.00% respectively, which was significantly higher than those (6.66% and 40.00%) of the ICM group (P<0.05), but the detection rates of thin and round left ventricular apex, arch-shaped left ventricle, SWMAs, and paradoxical ventricular wall motion were 53.33%, 66.66%, 46.66% and 20.00% respectively in the ICM group, which were markedly higher than those in the DCM group. The incidence rates of aortic valve, mitral valve, tricuspid valve and pulmonary valve in the DCM group were 66.66%, 100.00%, 46.66% and 76.66%, which were notably higher than those (36.66%, 93.33%, 26.66% and 40.00%) in the ICM group (P<0.05).
Conclusion:
ECG combined with UCG examination can effectively improve the judgment rate and diagnosis accuracy of cardiomyopathy. Due to its high safety, ECG combined with UCG examination is worthy of clinical promotion and application.
... As a multivariate analysis method, the logistic regression model is used to identify factors (x) that have a significant impact on a dependent variable (y) and predict the category of the dependent variable [15,16]. It was successfully applied in disease prevention [17,18], geology and meteorology [19,20], and social problem research [21,22]. ...
In order to realize the stability and inheritance of image characteristics in the development process of a series of products, we comprehensively analyzed the cognitive differences among users, designers, and engineers and propose a multicriteria decision system for an intelligent design method of product forms based on a logistic regression model, relative entropy theory, and preference mapping (PREFMAP). First, from the perspective of the role characteristics of the design subjects, an equilibrium evaluation model was constructed using the logistic regression model and relative entropy theory. Second, combining the multidimensional perception space and the characteristics measurement of the product form, the fitness function of the image form was constructed based on PREFMAP. Third, a genetic algorithm was applied to establish the intelligent image-style-oriented design method, which could guide the image form development of a product series through innovative design. Lastly, the method was verified by taking Audi A4L series headlights as an example. And the image evaluation of the two new schemes was greater than that of the previous seven generations of headlights. The results verify the effectiveness and feasibility of the method. In this paper, we structured a relatively preliminary model to explain the fusion of cognitive information. More subjective and objective factors, algorithms, and image recognition technology need to be further studied to improve the model in our future work.
