The essence of enterprise financial modeling is to use mathematical models to classify and sort out all kinds of enterprise information according to the main line of value creation and on this basis to complete the analysis, prediction, and value evaluation of enterprise financial situation. A reasonable financial model is also an effective means to reduce financial fraud. In this paper, a financial fraud identification model is constructed based on empirical data. In the process of model construction, the primary feature set is selected according to the financial fraud motivation theory, and then, the original feature set is obtained by Mann–Whitney test on the primary feature set, and the final fraud identification feature set is selected from the original feature set by using Relief and Boruta algorithms. Finally, based on the final fraud identification feature set, the data algorithms such as decision tree, logistic regression, support vector machine, and random forest are used to identify financial fraud. The experimental results show that the combination of financial fraud identification features constructed by the Relief algorithm and random forest model has the best recognition effect. The evaluation indexes of the G mean value and the F value were 75.86% and 78.33%, respectively. [ABSTRACT FROM AUTHOR]

Objective To compare the effect of long-term small dose of methimazole or radioiodine 131 on bone mineral density (BMD), cardiac function, and biochemical indexes in patients with recurrent hyperthyroidism. Methods Sixty-two patients with recurrent hyperthyroidism were randomly divided into two groups: drug treatment group and radioiodine treatment group. Twenty-eight patients took a long-term oral medication of methimazole, while 34 patients were given a radioiodine treatment. During the follow-up, the thyroid function, serum lipids and lipoproteins, echocardiography, and BMD were detected. Results The thyroid function of 28 patients in drug treatment group and 13 patients in radioiodine treatment group was normal, while the other 21 patients in radioiodine treatment group had hypothyroidism. The serum levels of lipids in drug treatment group were much lower than that in radioiodine treatment group, while no difference of BMD, white blood cell, liver function, and cardiac function was observed between the two groups. Conclusion Compared with radioiodine treatment, long-term small dose of methimazole treatment is safe for patients with recurrent hyperthyroidism. [ABSTRACT FROM AUTHOR]

Objective To evaluate the impact of drug therapy, radioiodine therapy, and surgical therapy in bone mineral density and biochemical bone turnover markers in patients with hyperthyroidism. Methods A total of 186 female patients with hyperthyroidism were enrolled in the study. They received drug therapy, radioiodine therapy, or surgical therapy according to the disease course and their own wish. Bone mineral density and biochemical bone turnover markers were compared at the time of enrollment and after 2-year treatment. Results Bone mineral density increased and biochemical bone turnover markers decreased significantly in all patients in 3 groups. No difference between bone mineral density and bone turnover markers were found among the 3 groups. Conclusion Drug therapy, radioiodine therapy, and surgical therapy improve bone mineral density and decrease biochemical markers of bone turnover in hyperthyroid patients. [ABSTRACT FROM AUTHOR]
