Objective To investigate the association of inducible nitric oxide synthetase (iNOS) expression with the expression of mutation type p53 (mt p53) in prostatic carcinoma (PCa). Methods The expression levels of iNOS and mt p53 were in 28 PCa specimens and 10 cases of benign prostatic hyperplasia (BPH) were detected by immunohistochemical method. Results The expression levels of both iNOS and mt p53 in PCa were higher than those in BPH. The expression of iNOS was related to the expression of p53 protein. Conclusion iNOS and mt p53 may play a role in the pathogenesis of PCa.

OBJECTIVE: Identifying Atrial Ventricular Hypertrophy Electrocardiogram (AVH ECG)and diagnosing the classification of theirs automatically. METHODS: The ECG data used in this experiment was collected from the First Affiliated Hospital of China Medical University. CNN are combined with conventional methods and a 10 layers of one dimensional CNN are created in this experiment to extract the features of ECG signals automatically and achieve the function of classifying. ROC, sensitivity and F1-score are used here to evaluate the effects of the model. RESULTS: In the experiment of identifying AVH ECG, the AUC of test dataset is 0.991, while in the experiment of classifying AVH ECG, the maximal F1-score can reach 0.992. CONCLUSIONS The CNN model created in this experiment can achieve the auxiliary diagnosis of AVH ECG.
