RESUMEN
Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.
RESUMEN

This article discussed the risks of bladder cancer and frailty, the necessity of preoperative frailty assessment in patients with bladder cancer, commonly used assessment tools, and summarized the limitations of the existing evaluation tools to provide reference for further developing and improving the frailty evaluation tools and applications for bladder cancer patients research provides reference.
RESUMEN
Despite recent studies, relatively few are known about the diversity of fungal communities in the deep Atlantic Ocean. In this study, we investigated the diversity of fungal communities in 15 different deep-sea sediments from the South Atlantic Ocean with a culturedependent approach followed by phylogenetic analysis of ITS sequences. A total of 29fungal strains were isolated from the 15 deep-sea sediments. These strains belong to four fungal genera, including Aspergillus, Cladosporium, Penicillium, and Alternaria. Penicillium, accounting for 44.8% of the total fungal isolates, was a dominant genus. The antiaflatoxigenic activity of these deep-sea fungal isolates was studied. Surprisingly, most of the strains showed moderate to strong antiaflatoxigenic activity. Four isolates, belonging to species of Penicillium polonicum, Penicillium chrysogenum, Aspergillus versicolor, and Cladosporium cladosporioides, could completely inhibit not only the mycelial growth of Aspergillus parasiticus mutant strain NFRI-95, but also the aflatoxin production. To our knowledge, this is the first report to investigate the antiaflatoxigenic activity of culturable deep-sea fungi. Our results provide new insights into the community composition of fungi in the deep South Atlantic Ocean. The high proportion of strains that displayed antiaflatoxigenic activity demonstrates that deep-sea fungi from the Atlantic Ocean are valuable resources for mining bioactive compounds.

RESUMEN
Objective To investigate the expression and clinical significance of apoptotic protease activating factor 1 (Apaf-1) and bax in prostate cancer (PCa) and benign prostatic hyperplasia (BPH). Methods Immunohistochemistry was used to detect the expression of Apaf-1 and bax in the tissues from 45 PCa patients and 60 BPH patients. Results The positive rates of Apaf-1 and bax in PCa tissues were 22.22%(10/45) and 20.00 % (9/45), respectively, while those in BPH tissues were 48.33 % (29/60) and 46.67 % (28/60). There was a statistically significant difference in the expressions of Apaf-1 and bax between two groups (P0.05), but they were correlated with the pathological grade and clinical stage of PCa (P< 0.05). The expressions of Apaf-1 and bax in PCa tissues were lower than those in BPH tissues. There was a positive correlation between the expression of Apaf-1 and bax (r=0.535, P<0.01). Conclusion Apaf-1 and bax might be correlated with the carcinogenesis and development of PCa.
