Considering that ensemble learning is an effective method of reducing the classifmation error of the classifier, this paper proposes a double-layer Bayesian classifier ensembles （DLBCE） algorithm based on frequent itemsets. DLBCE constructs a double-layer Bayesian classifier （DLBC） for each frequent itemset the new instance contained and finally ensembles all the classifiers by assigning different weight to different classifier according to the conditional mutual information. The experimental results show that the proposed algorithm outperforms other outstanding algorithms.展开更多

IL is characterized by dilated lymphatic vessles in the intestinal wall and small bowel mesentery which induceloss of protein and lymphocytes into bowel lumen. We here report a case of IL in a young male patient who was admitted for complaint of recurrent diarrhea for ten years and aggravation of the illness one year ago. He was diagnosed by endoscopy and confirmed by pathology as a primary IL and treated by parenteral nutrition support and Chinese herbs.展开更多

Methods: 90 patients with primary liver cancer who received interventional therapy from January 2021 to June 2022 in the First Affiliated Hospital of Nanjing Medical University were selected and divided into two groups. The control group received routine nursing, while the observation group received continuous nursing and nutritional support. The differences of each index between the two groups were compared. Results: the changes of serum total protein, albumin and quality of life scores in the observation group were higher than those in the control group (P<0.05);The satisfaction of the observation group was higher than that of the control group (P<0.05). Conclusion: the combination of continuous nursing and nutritional support has a good application effect, which can improve the total protein and albumin levels of patients and can be popularized.展开更多
