        • 腹腔鏡下經膽道鏡鈥激光碎石治療難治性膽管結石

          目的探討腹腔鏡下經膽道鏡鈥激光碎石治療難治性膽管結石的可行性和療效。 方法回顧性分析我院2009年6月至2014年12月期間18例腹腔鏡下經膽道鏡鈥激光碎石治療難治性膽管結石(無法在內鏡下乳頭括約肌切開取石術取出者)的臨床資料。 結果成功手術18例,手術時間60~200 min,平均130 min。一次性取凈結石16例,2例女性患者分別有四川、安徽生活居住史,術后造影在左、右肝管內再次發現絮狀結石,予熊去氧膽酸口服,隨訪至今,其中1例結石消失,另外1例仍有結石表現。術后均無膽管出血、膽瘺、膽管狹窄等并發癥發生。 結論對于難治性的膽管結石,腹腔鏡下經膽道鏡鈥激光碎石治療是一種安全、有效的方法。

        • Research of electrical impedance tomography based on multilayer artificial neural network optimized by Hadamard product for human-chest models

          Electrical impedance tomography (EIT) is a non-radiation, non-invasive visual diagnostic technique. In order to improve the imaging resolution and the removing artifacts capability of the reconstruction algorithms for electrical impedance imaging in human-chest models, the HMANN algorithm was proposed using the Hadamard product to optimize multilayer artificial neural networks (MANN). The reconstructed images of the HMANN algorithm were compared with those of the generalized vector sampled pattern matching (GVSPM) algorithm, truncated singular value decomposition (TSVD) algorithm, backpropagation (BP) neural network algorithm, and traditional MANN algorithm. The simulation results showed that the correlation coefficient of the reconstructed images obtained by the HMANN algorithm was increased by 17.30% in the circular cross-section models compared with the MANN algorithm. It was increased by 13.98% in the lung cross-section models. In the lung cross-section models, some of the correlation coefficients obtained by the HMANN algorithm would decrease. Nevertheless, the HMANN algorithm retained the image information of the MANN algorithm in all models, and the HMANN algorithm had fewer artifacts in the reconstructed images. The distinguishability between the objects and the background was better compared with the traditional MANN algorithm. The algorithm could improve the correlation coefficient of the reconstructed images, and effectively remove the artifacts, which provides a new direction to effectively improve the quality of the reconstructed images for EIT.

        • Status, problems and countermeasures of artificial intelligence application in medical education

          Human society has entered the age of artificial intelligence(AI). Medical practice and education are undergoing profound changes. The government strongly advocates the application of AI in the field of education and it has been incorporated into the national strategy. The integration of medical education and AI technology is changing the paradigm of modern medical education. This paper introduces the current application status of AI in medical education, and analyzes the existing problems and proposes corresponding resolutions, so as to lay a foundation for promoting the integration of medical education and AI.
